Edgar Filing: NATIONAL GRID PLC

People

If we are to achieve our strategic goals, we need to make sure our employees have the right skills and capabilities.

During 2013/14 we have focused particularly on the areas that we believe can generate the most value for the Company through our people – both now and in the future.

This has involved a focus on future leaders, operational leaders, engineers and stakeholder relationship managers. In addition to increasing our capability across these groups we also need to make sure we have enough people in each group. We will also be developing plans to improve our succession planning for our operational leader, engineer and stakeholder relationship manager roles.

Building skills and expertise

As we continue working under RIIO in the UK and become increasingly focused on driving performance on both sides of the Atlantic, we have identified three main business capabilities we need to develop among our workforce to support us in achieving our strategic objectives: performance excellence; customer and stakeholder management; and contract management.

We believe that by focusing on these capabilities we will make sure we meet our customers’ and stakeholders’ expectations while building a systematic approach to improving performance.

To help us do this, we have brought all our learning and development resources together under our Academy.

To date, 110 of our senior leaders in the UK have attended our performance excellence senior leadership programme through our Academy and similar programmes have started in the US.

Attracting the best people

We are involved in a number of initiatives to help attract new talent into our organisation and industry. In the UK, these include:

— working with the energy sector towards delivering 11,000 new

   apprenticeships and traineeships over the next three years through

   the Energy & Efficiency Industrial Partnership;

— developing our own people through Advanced Apprenticeships

   and engineer training;

— supporting power systems undergraduate bursaries through the

   Power Academy; and

— making sure our graduates continue their development throughout

   their career with us.

Initiatives in the US include:

— energy utility technology certificate programmes – partnerships

   with seven local community colleges to develop and prepare

   students to become future electric line workers;

— ‘Troops to Energy Jobs’ – a programme designed to help veterans

   determine how their military skills and experience translate into the

   skills we are looking for;

— real work experience and leadership training for qualified

   graduates in engineering and business disciplines; and

— summer internships – providing six to eight week opportunities

   for college students to gain work experience with us.

Safeguarding the future

In the UK, around 89,000 people are needed annually to meet demand in the UK’s engineering sector over the next decade, yet only around 51,000 are joining the profession each year.

To address this shortage, we are running or are involved with a number of programmes and initiatives aimed at encouraging young people to study STEM subjects. These include:

— ‘School Power’, which provides classroom resources,

   including a dedicated website, to support the teaching of STEM

   subjects;

— work experience, offering year 10 students a week-long

   residential course at our Eakring Academy (totalling 100 each

   year); and

— open house visits to our sites to give students and teachers an

   insight into gas and electricity systems, as well as future energy

   challenges.

We are leading a consortium of businesses to create an exhibition called ‘That Could Be Me’ at the Science Museum in London, which will provide insight into engineering as a career. It is due to launch in December 2014.

A further initiative, called ‘Careers Lab’, aims to help establish a coordinated approach towards businesses taking responsibility for the skills agenda. The pilot scheme, which began in January 2014, involves businesses and schools in the Midlands working together to progress careers advice programmes for young people.

In the US, overall engineering employment is expected to grow by 11% through to 2018, varying by specialty. By 2018, STEM occupations will account for about 1.1 million new jobs and 1.3 million replacement positions due to STEM workers leaving the workforce.

We are working with high schools and community colleges to build a curriculum that meets future workforce needs – and supporting STEM education at K-12 levels. An example of this is the National Grid Engineering Pipeline Program – a six year developmental journey designed to inspire young people to pursue an education and career in engineering. To date 164 young people have entered into the programme.

We also work closely with the National Centre for Energy Workforce Development on its ‘energy industry fundamentals’ curriculum and competency models.

02 National Grid Annual Report and Accounts 2013/14

Chairman’s

statement

It has been an important and challenging year for National Grid – and the energy sector in general – on both sides of the Atlantic.

Although we did not experience any major storm-related outages in our service areas during 2013/14, severe winter weather conditions – the polar vortex in the US and serious flooding in the UK – continued to test the resilience of our networks. I am pleased to report these have performed well as a result of prudent investments in past years, as well as the commitment of our people.

Energy policies in both the UK and US strive to find an acceptable balance between affordability to the ultimate consumers, security of supply and sustainability considerations. Particularly since last September, the focus of UK media and political attention has been moving between each of these three factors, with no enduring consensus of what constitutes the optimum position.

In the UK, the eight year RIIO settlement we accepted in February 2013 incentivises us to be as efficient as possible while ensuring that savings we achieve can be shared with consumers. Through these incentives we can maximise our efforts to help hard-pressed consumers and deliver good returns to our shareholders.

Transparency

In our continuing efforts to be fair, balanced and understandable in our reporting we are including additional information this year and explaining some technical matters in greater detail, so that we are as transparent as we can be.

In particular, I draw your attention to one aspect of our results. There have always been differences between IFRS reported results and underlying economic performance; however, one of the benefits of the RIIO price control regime is that it provides greater transparency of regulatory adjustments to

revenue in our principal UK businesses. The commentary on ‘timing differences and regulated revenue adjustments’ contained in the Financial review on page 08 aims to help understanding of this matter.

The Board has recommended an increase in the final dividend to 27.54p per ordinary share ($2.3107 per American Depositary Share). If approved, this will bring the full-year dividend to 42.03p per ordinary share ($3.4801 per American Depositary Share), an increase of 2.9% over the 40.85p per ordinary share in respect of the financial year ending 31 March 2013.

Effective governance

We have developed a new remuneration policy to align more closely with RIIO, the continued evolution of our US business and shareholder value creation. The policy will be subject to shareholder approval at the AGM in July – a requirement of recent legislation. You can read our full Remuneration Report, introduced by Jonathan Dawson, our new Remuneration Committee Chairman, on page 58.

As we describe on page 07, the high level of take-up of the scrip dividend in the last couple of years led to concerns about the potential dilutive effect of this option. This meant that we decided not to offer the scrip element for the 2013/14 interim dividend paid in January this year, as our forecast capital investment programme was already fully funded. I do appreciate, from the letters sent to me, that this caused some dissatisfaction. We have now identified a way of offering the scrip option for both the full-year and interim dividend, which balances shareholders’ appetite for the scrip dividend option with our cash requirements. At the AGM we are seeking approval for the allotment and buy-back authorities we need to do this. The scrip dividend option has been offered for the 2013/14 final dividend subject to shareholder approval of the relevant resolutions at the AGM.

The Board is proposing
a recommended final
dividend of

27.54p

(2012/13: 26.36p)

He will continue with his roles as President of the European Network of Transmission System Operators for Electricity (ENTSO-E) and as Chairman of National Grid Electricity Transmission (NGET) and National Grid Gas (NGG) through to July 2015 before leaving the Company. After July 2015, the role of President of ENTSO-E will no longer be undertaken within the Company, and arrangements for a smooth handover of Nick’s other responsibilities will be announced in due course.

This year we have welcomed Therese Esperdy and John Pettigrew to our Board and we will be saying goodbye to Maria Richter following the AGM.

During Maria’s 10 years with the Company she has made a significant contribution to the Board and Finance Committee in particular and I would like to thank her for her commitment and wish her all the best in her future endeavours.

Therese, who will be taking over as chairman of the Finance Committee from Maria, brings a wealth of corporate finance and debt market experience to our Board. We have also appointed a new Executive Director, John Pettigrew. John joined National Grid as a graduate entrant in 1991 and has been a member of the Executive Committee for nearly two years.

The appointments of Therese and John have been part of a significant transition of the Board over the last three years through which we have secured a broad range of skills, experience, perspectives and challenge. Together with strong teamwork, I believe these qualities are contributing towards an effective Board, which will continue to set the right tone from the top, helping to meet the challenges ahead.

contributed £1.4 billion in taxes in the UK alone. Additionally, we estimate we support more than 28,500 jobs in the first tier of our supply chain – companies that are our suppliers across the globe.

We aim to develop and operate our business with an inclusive and diverse culture. You can read more about our approach to diversity on page 41, as well as our Board diversity policy on page 56.

Looking ahead

Over the next 12 months the UK and US will see a dynamic political environment. In the UK, the Scottish independence referendum later this year and the general election in 2015 are likely to increase the focus on issues such as the affordability and security of energy supply, as will the proposed review of the energy industry by the Competition and Markets Authority.

In the US, the mid-term US Congressional elections are on the horizon, together with the gubernatorial elections (election of the state governor) in New York, Rhode Island and Massachusetts. We expect debate to continue on essential infrastructure, resilience and sustainability, including our Connect21 dialogue with stakeholders. You can read more about Connect21 on page 35.

Our people have a crucial role to play in meeting the opportunities ahead. I would like to thank our employees for their hard work and dedication over the past year. Rising to the challenges brought by severe weather and changes within the industry, they have continued to make National Grid a company we can be proud of.

Being a responsible business

Our vision statement ‘Connecting you to your energy today, trusted to help you meet your energy needs tomorrow’ emphasises the importance of trust, which we earn not just by meeting our commitments, but by making sure that we do so in the right way. That is why how we work is as important as what we do, and why doing the right thing is at the core of everything we do.

During 2013/14 we spent time reinforcing the standards we expect of our employees in terms of ethical behaviour. As part of this, we have sent our employees a refreshed copy of ‘Doing the Right Thing’, which is our guide to ethical business conduct.

We contribute to the communities in which we operate directly and indirectly in many ways. We maintain and operate the critical infrastructure needed to keep the lights on and the heating working across the UK and northeastern US; we employ more than 23,000 people; and in 2013/14

It has been a year of solid performance for National Grid against a backdrop of intense public focus on energy prices, as well as new regulatory frameworks in both the UK and US.

Safety is, as always, at the heart of the way we operate. In the UK we achieved an employee lost time injury frequency rate (IFR) of below 0.1. This is a world-class performance and I am incredibly proud of our teams who have worked so hard to get us to this significant milestone. You can read more about this achievement on page 10. The challenge now is to replicate this performance in the US, where we have more work to do. We will never let up on our relentless focus on safety.

Despite the freezing and protracted winter in the US and the wettest winter on record in the UK, we achieved one of our best years in terms of reliability, keeping the lights on and the gas flowing. The investment we made in bolstering our flood defences in the UK protected potentially vulnerable assets such as substations, even though in some cases the surrounding areas suffered considerable flooding.

In the US, our reliability performance was excellent as a result of continued targeted resiliency investment and management of our networks.

The introduction of RIIO in the UK has been an appropriate development for our industry. If we can outperform against the incentives it offers and find ways to reduce our costs, the benefits are shared with our customers. Getting ready for RIIO has been a significant challenge for the UK business, but I am delighted to say that we have made a good start.

There have also been significant Government and regulatory policy changes affecting our business in the UK, including the introduction of Electricity Market Reform (EMR) and the evolution of the system operator role in the long-term planning of the network.

We have adapted our ways of working so we can meet the needs of our customers and stakeholders and deliver value under RIIO. For example, we used innovative techniques to protect a section of the pipeline that carries gas from the liquefied natural gas (LNG) importation terminal in west Wales, prior to the construction of a new road. This meant we were able to meet the timescales of the local authority building the road without disrupting gas supply to consumers.

In the US, it has been the first year of working under the new upstate New York and Rhode Island regulatory contracts and I am pleased that we have performed well in both cases. You can read more about developments in our US rate filings and regulatory environment on page 164.

We have introduced Connect21, our thinking on advancing the USA’s natural gas and electricity infrastructure beyond its 20th century limitations (see page 35). Another priority in the US was the transition of the operation and maintenance of the Long Island Power Authority’s (LIPA) electric transmission and distribution system on Long Island to Public Service Electric and Gas Company – Long Island (PSEG-LI). We successfully handed over the contract on 31 December 2013 and have entered into a transition services agreement with LIPA/PSEG-LI.

US enterprise resource planning system stabilisation continued, remedying the errors of poor implementation from the prior year. Over the course of the year, the US business made significant progress in the activities required to upgrade the system, with implementation expected in mid-2014. The focus is now on reducing the ongoing costs associated with the complex manual processes that are required to compensate for identified weaknesses in internal controls over financial reporting in the US. While these control weaknesses have not reduced the quality of financial statements

produced, they have necessitated significant additional cost.

Overall, the business remains on track to successfully conclude the programme during 2014, with expected costs unchanged from the guidance provided last year.

We have focused on improving our end-to-end operating processes throughout the year. This has involved using hard facts and data to identify and prioritise areas for improvement, as well as harnessing ideas to help find more efficient ways of working to meet our stakeholders’ needs.

An area we know we can improve is customer service. We saw some good results such as reduced complaints in the UK and our scores for UK Gas Transmission, as well as increases in three out of our four US customer satisfaction scores. However, we know that we are not fully meeting our customers’ expectations for our gas connections process in the UK and US. We will stay focused on getting this right.

In the US, we supply gas and electricity to customers who have chosen us as their supplier. Our regulatory agreements allow us to recover the costs we incur when we buy gas and electricity. During 2013/14 we saw an increase in complaints about higher energy bills – a consequence of the colder weather affecting commodity costs during the winter.

Energy prices have been the subject of a continued high-profile debate in the UK. At National Grid, we believe transparency is crucial, explaining to customers the breakdown of the bill they receive. In the UK, we are investing significantly in our UK networks, but the impact of network costs on bills will remain flat in real terms over the RIIO period (2013/14 – 2020/21), based on the forecast revenues derived from Ofgem’s Final Proposals for RIIO.

In terms of our UK network upgrade plans, we are pleased with progress on the London Power Tunnels project and have now started site works on the HVDC link connecting Scotland and England. This joint venture with SP Transmission will support the export of low carbon Scottish generation.

In the US, our Brooklyn/Queens Interconnect project will connect our existing natural gas distribution systems in Brooklyn and Queens, which will ensure greater reliability and safety, provide additional capacity and meet future energy needs for customers. This is the first new gas pipeline to be installed in the area in 50 years.

We are determined to embed sustainability by seeking to combine innovation, engagement and efficiency – an example of which was a trial in the UK, working with manufacturers, construction partners and our procurement teams to re-manufacture aluminium overhead line conductors.

People

I was really pleased to see that the results of our 2014 employee opinion survey, completed by 78% of our employees, included an engagement score of 71% – an increase of eight percentage points over the previous survey and our highest engagement score since we started conducting Group-wide employee opinion surveys.

I was also pleased to attend a series of celebrations to mark 40 years’ service for more than 300 of our employees in both the UK and US. I am delighted that so many of our people have forged productive and committed careers at National Grid that have spanned such a long time. Yet at the same time, it serves as a reminder about the scale of the challenge we have in our industry to make sure we have enough people with the skills and experience we need in the future.

It is a significant challenge on both sides of the Atlantic. In the UK, for example, around 89,000 people are needed annually to meet demand in the UK’s engineering sector over the next decade. Yet only around 51,000 are joining the profession each year. In the US, by 2018, STEM occupations will account for about 1.1 million new jobs and 1.3 million replacement positions due to STEM workers leaving the workforce.

To help address this shortage, National Grid is running, or is involved with, a number of programmes and initiatives in the UK and US aimed at encouraging young people to study STEM subjects – you can read more about these initiatives on page 40.

Our priorities for next year

• Safety – build on our strong UK performance and focus our efforts on delivering consistent world-class safety performance across the organisation;

• Customer-focused execution – in the UK, continue our strong start to RIIO; underpin energy security through our interconnector and infrastructure investment strategy. In the US, complete stabilisation of our enterprise resource system; perform strongly against our current regulatory rate plans while shaping the future; and

• Stakeholders – continue to engage with our stakeholders in the US, UK and EU to understand their changing energy needs and to shape energy policy.

Financial

review

We have delivered another year of solid

financial performance with a good start

under RIIO in the UK and consolidation

of underlying improvements in the US.

Our financial KPIs

Adjusted earnings per share

Adjusted operating profit

Our adjusted operating profit has increased by £25 million (1%) to £3,664 million. Across our three UK businesses operating under the new RIIO framework, adjusted operating profit was up £34 million. Allowed revenues increased in Electricity Transmission and Gas Distribution and fell in Gas Transmission. The resultant increase in revenue was offset by higher controllable costs, higher depreciation as a result of continued investment and adverse movements in timing year on year.

Our US Regulated business was £129 million lower, reflecting a weaker dollar, the end of Niagara Mohawk deferral recoveries at March 2013, higher controllable costs due to inflation, and increased insurance costs following major storms last year. These were partially offset by the non-recurrence of the major storm costs incurred last year.

Other activities adjusted operating profit was £120 million higher, driven by higher profits in the French interconnector, non-recurrence of Superstorm Sandy costs in our insurance captive, and improved performance in our Metering business. These were partially offset by increased spend on the stabilisation of new US information systems.

Adjusted earnings

Our adjusted net interest charge was slightly lower than 2012/13 at £1,108 million, reflecting the weaker dollar.

Our adjusted tax charge was £38 million lower at £581 million. This was mainly due to a 1% decrease in the UK statutory corporation tax rate in the year, a change in the UK/US profit mix and changes in tax provisions in respect of prior years. As a result of this, our effective tax rate for 2013/14 was 22.5% (2012/13: 24.4%).

The earnings performance described above has translated into adjusted EPS growth in 2013/14 of 2.6p (5%) (2012/13: 5.4p, 12%).

Group return on equity (RoE) We measure our performance in generating value for our shareholders by dividing our annual return by our equity base. Group RoE has increased during the year to 11.4%, due to the impact of major storms in the prior year. Excluding major storms, Group RoE has decreased by 30bps reflecting the end of Niagara Mohawk deferral recoveries, together with higher controllable costs and system costs in the US. These negative impacts were partially offset by French interconnector performance and the lower UK tax rate. Group return on equity %

Additional Information

We have changed the way we present our financial information in the Strategic Report to remove duplication. As a result, the analysis here focuses on our KPIs and other performance measures we use to monitor our business performance. Analysis of our financial performance and position at 31 March 2014, including the performance of our principal operations, has been relocated to the financial statements, however this analysis still forms part of our Strategic Report financial review. See page 75 for further information. See pages 183 to 185 for commentary on our financial performance and position for the year ended 31 March 2013 compared with 2012.

Regulated asset growth

Our regulated assets have increased by 3% (£1 billion) to £34.7 billion, reflecting the continued high levels of investment in our networks in both the UK and US. Maintaining efficient growth in our regulated assets ensures we are well positioned to continue providing consistently high levels of service to our customers and increases our revenue allowances in future years.

The UK regulatory asset value (RAV) increased by £1.1 billion, reflecting inflation and significant capital expenditure in our UK Electricity Transmission business in particular. The US rate base decreased by £0.1 billion. Foreign exchange movements decreased the rate base reported in sterling by £0.9 billion. Offsetting this, investment in the networks and working capital movements increased rate base by £0.8 billion.

The Board is confident that growth in assets, earnings and cash flows, supported by improving cash efficiency and an exposure to attractive regulatory markets, should help the Group to maintain strong, stable credit ratings and a consistent prudent level of gearing, while delivering attractive returns for shareholders.

Other performance measures

Dividend growth

During the year we generated £1.3 billion of sustainable business net cash flow after our capital expenditure programmes. This has enabled the growth of the dividend in line with RPI, being 2.9%(2012/13: dividend growth of 4%), taking into account the recommended final dividend of 27.54p.

The high level of take-up of this scrip option in the last couple of years has led to concerns about the potential dilutive effect on value of this option. This meant that we decided not to offer the scrip element for the 2013/14 interim dividend paid in January this year, as our forecast capital programme was already fully funded. We continue to offer the scrip option for the year-end dividend.

Dividend growth

Value added

Our dividend is an important part of our returns to shareholders along with growth in the value of the asset base attributable to equity investors. These are reflected in the value added metric that will underpin our approach to sustainable decision making and long-term incentive arrangements.

Overall value added in the year was £2.1 billion or 57.2p per share as set out below:

Cash generated from operations

Cash generated from operations was £4,419 million (2012/13: £4,037 million). Adjusted operating profit before depreciation, amortisation and impairment was £81 million higher year on year. Changes in working capital improved by £351 million over the prior year, principally in the US due to the timing of receivables from LIPA relating to Superstorm Sandy, higher commodity costs and weather differences year on year. Partially offsetting these improvements, cash outflows relating to exceptional items were £38 million higher due to reorganisation in the UK and LIPA MSA transition costs in the US.

UK regulated return on equity

The UK RoE has decreased 90bps to 12.7%, reflecting the new regulatory arrangements under the RIIO framework in place from this year. This performance represents 260bps outperformance over allowed returns.

Return on capital employed

RoCE provides a performance comparison between our regulated UK and US businesses and is one of the measures that we use to make strategic and investment decisions about our portfolio of businesses. The table below shows the RoCE for our businesses over the last five years:

Return on capital employed

LOGO

The UK RoCE has decreased from 8.6% to 8.0% in 2013/14, reflecting the new RIIO regulatory allowances, including lower cost of debt allowance, higher gearing assumption in the gas businesses, and the inclusion of our share of exceptional costs. The decrease in the US RoCE from 7.1% to 6.4% is primarily due to the end of Niagara Mohawk deferral recoveries and controllable cost increases. Excluding the impact of major storm costs, the US RoCE would have been 7.7% in 2012/13.

Net debt

We expect our net debt to continue to grow for the next few years as we fund our capital investment programmes and enhance our networks. We continue to borrow at attractive rates when needed and believe that the level of net debt remains appropriate for our business. Our five year net debt trend is shown on page 91.

Timing and regulated revenue adjustments

As described on page 20, our allowed revenues are set in accordance with our regulatory price controls or rate plans. We calculate the tariffs we charge our customers based on the estimated volume of energy we expect will be delivered during the coming period. The actual volumes delivered will differ from this estimate. Therefore, our total actual revenue will be different from our total allowed revenue. These differences are commonly referred to as timing differences.

If we collect more than the allowed level of revenue, the balance must be returned to customers in subsequent periods, and if we collect less than the allowed level of revenue we may recover the balance from customers in subsequent periods. In the US, a substantial portion of our costs are pass-through costs (including commodity and energy efficiency costs) and are fully recoverable from our customers. Timing differences between costs of this type being incurred and their recovery through revenue are also included in timing.

The amounts calculated as timing differences are estimates and subject to change until the variables that determine allowed revenue are final.

Our operating profit for the year includes a total estimated in-year under-collection of £42 million (2012/13: £16 million over-collection). Our closing balance at 31 March 2014 was £60 million over-recovered.

In the UK, there was a cumulative under-recovery of £57 million at 31 March 2014 (2013: under-recovery of £5 million). All other things being equal, the majority of that balance will normally be recoverable from customers starting in the year ending 31 March 2016.

Strategic Report

Corporate Governance

Financial Statements

Additional Information

In the US, cumulative timing over-recoveries at 31 March 2014 were £117 million (2013: £110 million). The majority of that balance will be returned to customers next year.

In addition to the timing adjustments described above, following the start of the RIIO price controls in the UK, outperformance against allowances as a result of the totex incentive mechanism, together with changes in output-related allowances included in the original price control, will almost always be adjusted in future revenue recoveries, typically starting in two years’ time.

Our current IFRS revenues and earnings include the amounts that will need to be repaid but exclude amounts that will be recovered in future periods. Such adjustments will form an important part of the continuing difference between reported IFRS results and underlying economic performance based on our regulatory obligations.

For our UK regulated businesses as a whole, regulated revenue adjustments totalled £106 million in the year. This is based on our estimates of: work carried out in line with allowances; in expectation of future allowances; or work avoided altogether – either as a result of us finding innovative solutions or of the need being permanently removed.

In the US, accumulated regulatory entitlements to future revenue net of over- or under-recoveries amounted to £1,027 million at 31 March 2014 (2013: £1,311 million). These entitlements cover a range of different areas, with the most significant being environmental remediation and pension assets, as well as deferred storm costs.

All regulatory entitlements are recoverable (or repayable) over different periods, which are agreed with the regulators to match the expected payment profile for the liabilities. As at 31 March 2014, these extend until 2059.

Major storms

Despite the very cold winter across much of the US, there were no major storms in 2013/14. In 2012/13, two major storms in the US, Superstorm Sandy and Storm Nemo, as well as a number of smaller storms, had a material effect on the results of National Grid, reducing operating profit by £136 million.

We measure the achievement of our objectives, make operational and investment decisions and reward our employees using both qualitative assessments and quantitative indicators. To provide a full and rounded view of our business, we use non-financial as well as financial measures. Although all these measures are important, some are considered to be more significant than others, and these are designated as KPIs.

KPIs are used to measure our progress on strategic priorities, aligning with those activities that combine to deliver our strategy. Financial KPIs are trailing indicators of the success of past initiatives and specific programmes. They also highlight areas for further improvement and allow us to make sure our actions culminate in sustainable long-term growth in shareholder value.

We have changed our financial KPIs during 2013/14 to reflect the changing metrics used to monitor the Group following RIIO. We have included ‘value added’, a new metric that we use to

monitor the value delivered to shareholders through dividends and growth in the value of National Grid’s assets net of the growth in net debt. A derivative of this metric, value growth, is also used to incentivise our Executive Directors. See page 58 for further detail on our remuneration policy.

We have included regulated asset growth, as this is a measure of the ability of the business to generate revenue in the future. While we continue to focus on efficient capital expenditure, the value of our regulated assets drives our revenue allowances in future years.

We have stopped reporting our regulated controllable operating costs metric. This was included to monitor cost control, but following the introduction of RIIO, all our businesses’ activities are focused on costs, through innovative and efficient delivery of high-quality services. Our ability to control costs is also reflected in the adjusted EPS and Group RoE metrics, which are based on our adjusted earnings.

Employee engagement index %
Definition Employee engagement index calculated using responses to our employee survey. Target To increase	We measure employee engagement through our employee opinion survey. The results of our 2014 survey, which was completed by 78% of our employees, have helped us identify specific areas where we are performing well and those areas we need to improve. Our engagement index has risen by eight points to 71%, our highest engagement score since we started conducting Group-wide employee opinion surveys. Managers receive a scorecard that aims to create greater leadership accountability and we produce survey reports and action plans at Company, regional, business unit, function and team levels.

Greenhouse gas emissions % reduction against 1990 baseline
Definition Percentage reduction in greenhouse gas emissions against our 1990 baseline. Target 45% reduction by 2020 and 80% reduction by 2050 Our total Scope 1 and Scope 2 greenhouse gas emissions (excluding electricity transmission and distribution line losses) for 2013/14 were around 7.4 million tonnes carbon dioxide equivalent (Scope 1 was 7.2 and Scope 2 was 0.2). This is equivalent to an intensity of 501 tonnes carbon dioxide equivalent per £million of revenue for 2013/14. The 2013/14 emissions quantity represents a 62% reduction from our 1990 baseline and a 9% reduction from our 2012/13 emissions. Although our outturn is better than our 2020 target, we will need to innovate if we are to meet the target for 2050. We have remained focused on greenhouse gas emissions reduction programmes to achieve our corporate commitment targets of 45% and 80% reduction in Scope 1 and 2 emissions by 2020 and 2050 respectively from our 1990 baseline.	We continue to look for innovations and efficiencies that will help us achieve these targets. In 2013 we significantly improved our scores in the CDP Global 500 ratings and were admitted for the first time to the Global Leaders Index for carbon disclosure. We measure and report our greenhouse gas emissions in accordance with the WRI/WBCSD Greenhouse Gas Protocol: Corporate Accounting and Reporting Standard (Revised Edition) for all six Kyoto gases, using the operational control approach for emissions accounting. These Scope 1 and 2 emissions are independently assured against the international standard ISO 14064-3 Greenhouse Gas assurance protocol. A copy of this statement of assurance is available on our website. In the UK we have experienced a mild year, which has been beneficial to the overall emissions of many of our business units. In the UK activities at Grain LNG have led to a 60% reduction of energy consumption of on-site nitrogen production. Our Electricity Transmission business has reduced SF₆ leak rates to 1.2% in 2013/14 compared with 1.7% in the previous year and our Property function has delivered a 2% year-on-year reduction in electricity-related emissions across occupied sites. In the US we have completed power plant turbine efficiency upgrades in Long Island and continued to focus on efficiency-related maintenance programmes. This has contributed towards outperforming our LIPA contractual efficiency target. Our US and UK Gas Distribution businesses have continued to deliver significant reductions in emissions in line with forecasts.	Strategic element Embed sustainability

12 National Grid Annual Report and Accounts 2013/14


		Operating environment		Recent signs of economic growth have had a positive effect on consumer confidence, but the long downturn and its impact on wages have led to widespread concerns over energy bills. Affordability remains a primary concern of consumers and regulators.




		Economic environment Our UK price controls and US rate plans are agreed against the backdrop of the broader macroeconomic environment. In the UK, economic growth is projected to continue to increase at a moderate pace in 2014, while the RPI measure of inflation is expected to remain subdued. Monetary policymakers have indicated that interest rates are expected to remain low during 2014, despite significant reductions in unemployment. In the US, employment and GDP growth continue to improve steadily. The US Congress has reached a two year budget deal, which should ease some concerns in market conditions. Market indicators in areas such as housing and construction are returning to pre-2008 levels.
		Market driver		Impact
		Changing energy mix
		Cost and environmental pressures affecting traditional electricity generation Older gas-fired power stations in the UK and many coal-fired power stations in the US are closing or being mothballed due to changes in environmental regulations. In the UK, fuel prices are affecting the economic viability of fossil fuel-fired electricity generation. Further decline in traditional electricity generation is likely if the UK’s carbon reduction targets are to be met. The US is seeing renewed demand for gas, as the increasing availability of shale gas has lowered prices.		Long-term certainty needed to secure investment Current uncertainty in the UK market has led some developers to delay investing in new generation capacity. An agreement on long-term prices for low carbon generation under Electricity Market Reform (EMR) could provide additional certainty for these developers.
		Changing UK energy sources The locations where gas comes into the UK are changing, with forecast reductions in North Sea production and increased reliance on imported gas. New low carbon generation may not be located in the same place or have the same characteristics as existing plant.		This means changes to our network will be needed Changes to the energy mix and location of supply and demand centres will create pressures on our networks, potentially requiring further investment.
		Shale gas production is transforming supply and demand In the US, shale gas production will mean lower-priced gas over the long term, changing supply and demand patterns.		We may need to invest in additional network capacity As more generation plants convert to lower priced natural gas, we may need to invest in additional gas network capacity. Changes in generation could also mean modifications to the electricity transmission network.
		Energy policy
		Sustainability, security of supply and affordability underpin EU policy In a difficult economic and financial context, the EU’s energy policy is underpinned by the three cornerstones of sustainability, security of supply and affordability. The European Commission published its 2030 Climate Change and Energy framework in 2014, featuring a continued ambition in terms of greenhouse gas reduction targets and energy policy objectives. Negotiations for a new international agreement on climate change continued at the nineteenth session of the Conference of the Parties (COP19) in 2013, and nations are looking to the Paris worldwide conference in 2015 as the next opportunity to work out a new climate change deal.		Policy decisions can affect our investment needs and compliance obligations Energy policy decisions by governments, government authorities and others have a direct impact on our business, influencing the emerging challenges and opportunities. They can affect the amount and location of investment required in our networks and the way we operate. They can also change our compliance obligations. This requires more market integration, interconnection and renewable generation Greater levels of market integration, interconnection and renewable generation are fundamental to achieving the EU’s policy objectives. While European developments present challenges, the significant level of investment required may create opportunities for growth. For example, potential future interconnector opportunities include connections between the UK and Belgium, Norway, France, Ireland, Denmark and Iceland.

				Market driver				Impact
				UK policy changes are in place to attract investment				National Grid has been asked to play a key delivery role
				In the UK, energy policy continues to evolve from the Climate Change Act 2008, which commits the UK Government to reducing UK greenhouse gas emissions to at least 80% lower than a 1990 baseline by 2050. The Energy Act 2013 implements the main aspects of Electricity Market Reform (EMR), and puts in place measures to attract the investment needed to replace current generating capacity and upgrade the grid by 2020, and to cope with a rising demand for electricity.				In the UK, National Grid has been asked to play a major role as the delivery body for EMR, to be conferred on National Grid by Government in secondary legislation.
				US policy is evolving to meet environmental and energy diversity goals				Options for increased renewable and distributed generation are being explored
				In the US, many federal level developments have been through federal agency regulations and Presidential executive orders. At a state level, energy policy continues to evolve in the northeastern US, driven by interest in promoting energy efficiency, maintaining reliability and deploying renewable technologies that help meet environmental and energy diversity goals.				In the US, the impact on natural gas dependency has resulted in an evaluation of the best way of increasing fuel diversity through renewable and distributed generation resources. We continue to support movement towards a clean energy economy; and support additional measures to increase America’s energy productivity.
				Regulation
				Infrastructure investment needs must be balanced with affordability				We must accommodate customers’ cost concerns and also provide safe, up-to-date systems
				Regulators acknowledge that there is a significant need for infrastructure investment. However, affordability continues to be a primary concern. Cast iron gas mains still in use can be more than 100 years old, becoming riskier to use and contributing to greenhouse gas emissions through leaks. Severe weather in recent years has also highlighted the potential need for additional investment in network resilience. Regulators and policymakers are beginning to ask utilities to put plans in place to strengthen their networks’ ability to withstand the effects of severe weather.				We must accommodate our customers’ affordability concerns while fulfilling our obligations to provide safe and reliable services and upgrading our systems. Investment is required for new connections, to meet the challenges of changing supply and demand patterns, and to replace ageing infrastructure in the UK and US.
				UK regulators want greater efficiency and innovation				This is driving them to favour more market competition
				In the UK, the regulatory focus during the year has been on the new RIIO price controls which give greater focus to incentives and innovation than the previous regulatory regime.				In the UK, competition is already in place for offshore development and Ofgem has stated its intent to retain the option of using greater competition for certain large onshore projects.
				The projected increase in offshore wind generation and interconnection has created a debate on the regulatory approach to electricity transmission investment – a debate we continue to be fully engaged in.				For more information about network efficiency and innovation, see pages 30, 31 and 33.
				US policymakers are focused on grid modernization In the US, we are actively involved in the New York Energy Highway initiative to examine new ways of delivering infrastructure in the state. In Massachusetts, we are working with regulators and policymakers on a new grid modernisation policy. This is ongoing but is likely to affect our investments in smart grid and metering, and cost recovery of electric infrastructure investments.				This will present opportunities to address customers’ needs more effectively In the US, developments like the New York Energy Highway initiative, the Reforming Energy Vision initiative announced by the Governor of New York, the Massachusetts Grid Modernization regulatory proceeding and our Connect21 dialogue with stakeholders, will help present new opportunities to respond to customers’ needs and build the necessary infrastructure to address them.
				Innovation and technology
				Technology developments have the potential to reshape our market There is continued significant technological development in the energy sector as new technologies take shape and approach commercial viability. HVDC technology could play an important part in the development of a more integrated electricity grid, particularly the extension of offshore links.				This influences demand and helps us to manage supply While carbon-based generation is likely to remain a significant part of the global energy mix, carbon capture and storage technologies may become critical to governments achieving their climate change targets. Technologies such as energy storage, electric transportation and distributed generation all have the potential to affect our networks significantly. New consumer products, such as alternative fuelled vehicles and distributed generation, will increase demand and require new infrastructure. Smart grids will change the way loads are balanced across the distribution network, allowing our customers to make smarter energy choices and increasing network flexibility. Our infrastructure needs the flexibility to respond innovatively to emerging developments, potentially by being managed differently rather than by creating new infrastructure to meet supply and demand changes.

System operator

As system operator (SO) for England and Wales, we coordinate and direct electricity flows onto and over the transmission system, balancing generation supply and user demand. Where necessary, we pay sources of supply and demand to increase or decrease their generation or usage.

We have the same role for the two high voltage electricity transmission networks in Scotland and we have been appointed as system operator for the offshore electricity transmission regime.

Our charges for SO services in the UK are subject to a price control approved by Ofgem. System users pay us for connection, for using the system and balancing services.

As electricity transmission system operator, our price control includes incentives to minimise the costs and associated risks of balancing the system through buying and selling energy, as well as procuring balancing services from industry participants.

In the US, similar services are provided by independent system operators.

How we make

money from

our regulated

assets

Our transmission and distribution businesses
operate as regulated monopolies. Regulators
safeguard customers’ interests by setting the
level of charges we are allowed to pass on,

so that we provide value for money while

maintaining safe and reliable networks,

and deliver good customer service.

In the UK we have one regulator for our businesses, Ofgem. In the US, different services and locations are regulated by different bodies. For the areas in which we operate, these are the relevant state regulators and FERC.

Each of our regulatory agreements can include differences in structure, terms and values, which we summarise below. You can find more details about regulatory agreements on pages 160 to 165.

The value of our regulated assets is calculated based on the terms of our regulatory agreements. In the UK, the value of regulated assets is also indexed for inflation.

Our regulatory agreements also determine the amount we are allowed to charge customers, commonly referred to as our allowed revenues. Allowed revenue is calculated based on a number of factors:

Depreciation of regulated assets – the value of regulated assets is depreciated over an anticipated lifespan. The amount of depreciation is included in our allowed revenue, which represents the repayment of the amount we have invested in the asset.

Return on equity and cost of debt – regulated assets are funded through debt or equity. Regulatory agreements set this ratio. The equity portion earns a ‘return on equity’. This represents the profit we can earn on our investment in regulated assets. The debt portion earns an allowance based on the cost of debt (interest costs).

Some regulatory agreements allow us to charge customers based on the interest we pay; others use an external benchmark interest rate to incentivise us to raise debt efficiently. The benchmark interest method also provides an opportunity to outperform our regulatory allowance.

Cost of service – in establishing our regulatory agreements, our regulators consider what costs an efficiently run company would incur to operate and maintain our networks. They vary and examples can include costs relating to employees, office rental, IT systems and taxes.

The regulators have different approaches to determining what is considered an efficient or prudent cost and this may be different to the actual costs we incur.

Investment in network assets – in the UK we are given a cost allowance to make necessary investments in the networks. These investment costs allowed by the regulator are linked to the outputs delivered by the networks.

Performance against incentives – our regulatory agreements, mainly in the UK, include incentives that are designed to encourage specific actions, such as reducing greenhouse gas emissions.

Outperforming against incentive targets can increase our allowed revenues in the current year or a future year. Failing to achieve certain minimum targets may lead to a reduction in our allowed revenue.

A further incentive mechanism enables customers and shareholders to share the difference between allowed and actual costs via adjustments to revenue.

Commodity costs – in the US, we supply gas and electricity to customers who have chosen us as their supplier. Most of our regulatory agreements include mechanisms known as trackers that allow us to recover the costs we incur when we buy gas and electricity.

Deferrals – the costs we incur may not be included in the calculation of allowed revenue in the same year. Instead, these are deferred for regulatory purposes and we can normally recover them in future years. See pages 08 and 09 of the Financial review.

For example, in the US we incur costs restoring power to customers immediately after a major storm. However, these costs will generally be included in allowed revenue over a number of years and may not start until the relevant regulator has approved a request. This can be some time after the storm and may not cover all the costs.

Timing – our regulated revenue entitlements are set based on our regulatory price controls. We use forecast energy volumes that we expect to deliver to set the billing tariff. Where there is a difference between the actual and estimated energy volumes, the amount of revenue we collect will be different. Differences arising from volume and revenue entitlement changes are typically collectable in the following year for the US. For information about timing in the UK, see pages 08 and 09.

Customer and community value

Our business model – a virtuous circle of growth

Safety and reliability – we aim to provide reliable networks safely, which is essential to safeguard our customers, employees and the communities in which we operate.

LOGO

Affordability – we aim to provide services in a cost-efficient way, which helps to reduce the impact on customer bills.

Customer service – providing essential services that meet the needs of our customers and communities is a crucial part of the value they expect from us.

Sustainability – we aim to protect the environment and preserve resources for current and future generations.

Emergency services – we provide telephone call centres, coordinate the response to gas emergencies, and respond to severe weather events.

Community engagement – we listen to the communities we serve and work hard to

address concerns about the development of our networks. Our employees volunteer for community-based projects and we support educational initiatives in schools.

Shareholder value

Regulatory frameworks – operating within sound regulatory frameworks provides stability. Ensuring these frameworks maintain a balance between risk and return underpins our investment proposition.

Reputation – our approach to safety and our reliability record underpin our reputation. These are important factors that enable positive participation in regulatory discussions and the pursuit of new business opportunities.

Efficient operations – efficient capital and operational expenditure allows us to deliver network services at a lower cost and reduces working capital requirements.

Customers and communities – our focus on safety and reliability, as well as efficient investment in our networks, means that we are able to provide our customers and the communities in which we operate with the highest quality service we can. This makes sure they are able to access vital and reliable services whenever they need, wherever we operate.

Reinvestment in our business – to continue generating reasonable returns for our shareholders and revenue growth, we reinvest efficiently in our regulated assets. This is critical to the sustainability of our business. By challenging our investment decisions, we continue to deliver reliable, cost-effective networks that benefit our customers.

Revenue – the majority of our revenue is set in accordance with our regulatory agreements. This allows us a level of certainty over future revenues if we continue to meet safety and reliability targets, as well as the efficiency and innovation targets included in the new RIIO licence agreements in our UK regulated businesses.

Cash flow – our ability to convert revenue to cash is an important factor in the ongoing reinvestment in our business and our ability to provide sustainable value growth for our shareholders. Our focus on efficient development of our networks is important in maximising free cash flow.

Maximising incentives – positive performance under incentive mechanisms, and delivery of the outputs our customers and regulatory stakeholders require, helps us to make the most of our allowed returns.

Funding and cash flow management – securing low cost funding and carefully managing our cash flows are essential to maintaining strong returns for our investors.

Disciplined investment – we can achieve future revenue and earnings growth by increasing our regulatory asset value and rate base in line with regulatory capital allowances. Investment in non-regulated assets helps us to use and enhance our core capabilities with the aim of delivering attractive returns.

		Internal control and risk management
		National Grid is exposed to a variety of uncertainties that could have a material adverse effect on: Ÿ the Company’s financial condition; Ÿ our operational results; Ÿ our reputation; and Ÿ the value and liquidity of our shares. The Board is committed to protecting and enhancing our reputation and assets, while safeguarding the interests of our shareholders. It has overall responsibility for the Company’s system of risk management and internal control. Below, we describe the main arrangements put in place so that the Board can carry out this responsibility and so that its members can be assured of the integrity of the Company’s risk management and internal control systems, financial information and financial controls. Risk management approach Our Company-wide corporate risk management process provides a framework through which we can consistently identify, assess, prioritise, manage and report risks. It is designed to support delivery of our strategic and business objectives described on pages 14 and 15. The risks we identify are collated in risk registers and are reported at functional and regional levels of the Company. These registers include an assessment of how likely it is that each risk will materialise. They highlight the potential ‘worst case credible’ financial and reputational impact of the risk and details of mitigation activities. The risk registers also describe the adequacy of our existing risk controls. The main risks for our UK and US businesses are summarised and are reviewed, reported and discussed regularly by our senior leadership team. In addition, we also record the main strategic risks for the Company which are developed through discussions with the Executive leadership team. These risks are reported and discussed with the Executive Committee and Audit Committee every six months and by the Chief Executive through quarterly performance reports. During 2013/14 the Board reviewed the main elements of our risk management process. This included validating the risks included in our corporate risk profile and consideration of how we treat special categories of risks, such as potential extreme catastrophic events and emerging risks (uncertainties that are still developing). The results of the Board review are being incorporated into the ongoing work of the Corporate Risk team.						Our Board also sets and monitors risk appetite annually. We have a framework that differentiates our appetite for risk by categories. At the annual review meeting, the Board compares the decisions the Company has taken to the appetite level in each category. It then considers the appropriate appetite levels to set for the year ahead. Our principal risks Accepting that it is not possible to identify, anticipate or eliminate every risk that may arise and that risk is an inherent part of doing business, our risk management process aims to provide reasonable assurance that we understand and manage the main uncertainties that we face in delivering our objectives. This includes consideration of inherent risks, which exist because of the nature of day-to-day operations in our industry. An overview of the key inherent risks we face is provided on pages 167 to 169. Examples include: Ÿ aspects of the work we do could potentially harm employees, contractors, members of the public or the environment; Ÿ we may suffer a major network failure or interruption, or may not be able to carry out critical non-network operations due to the failure of technology supporting our business-critical processes; Ÿ changes in foreign currency rates, interest rates or commodity prices could materially impact earnings or our financial condition; Ÿ an inability to access capital markets at commercially acceptable interest rates could affect how we maintain and grow our businesses; and Ÿ customers and counterparties may not perform their obligations.

Principal risks
Our corporate risk profile contains the principal risks that the Board considers to be the main ones currently faced by the Company. An overview of these risks is provided below, together with examples of the relevant controls and mitigating actions we are taking.
Strategic objective	Risk description	Example of mitigations
Deliver growth	Failure to identify the right opportunities to execute our strategic ambition. Failure to sufficiently grow our core business and have viable options for new business over the longer term would negatively affect the Group’s credibility and jeopardise the achievement of intended financial returns. Our ability to achieve our ambition for growth is subject to a wide range of external uncertainties, including the availability of potential investment targets and attractive financing; and internal uncertainties, such as the performance of our operating businesses and our business planning model assumptions.	Ÿ We regularly monitor and analyse market conditions, competitors and their potential strategies, as well as the performance of our Group portfolio. We are also looking to access new sources of finance and capabilities through partnering. Ÿ We have internal processes for reviewing and approving investments in new businesses, disposals of existing ones and organic growth investment opportunities. These processes are reviewed regularly to make sure our approach supports our short- and long-term strategies. We undertake due diligence exercises on investment or partnering opportunities and carry out post-investment reviews to make sure we learn lessons for the future.
Engage externally	Inability to influence future energy policy. Policy decisions by regulators, governments and others directly affect our business. We must engage widely in the energy policy debate, making sure our position and perspective help to shape future policy direction.	Ÿ In the UK, we are working closely with DECC on Electricity Market Reform (EMR) plans. We have also restructured our business so we are prepared for our new role under EMR and to make sure we are well positioned to deliver value under RIIO. The Board is also continuing to monitor the increasing public debate around the cost, availability, security and sustainability of UK energy supplies.
		Ÿ In the US, we have begun to engage our external stakeholders about the role of the utility company of the future, under the banner of Connect21. We believe this conversation will help shape the regulatory and fiscal regime in the US in the future. We are maintaining our jurisdictional focus and we will continue to file new rate cases so our businesses can earn a fair and reasonable rate of return. Our rate filings include structural changes where appropriate, such as revenue decoupling mechanisms, capital trackers, commodity-related bad debt true-ups and pension and other post-employment benefit true-ups, as described on pages 162 to 165.
Engage our people	Inability to secure the business capacity, appropriate leadership capability and employee engagement levels required to deliver our vision and strategy. It is through the high-quality work of our employees that we will achieve our vision, respond to the changing needs of our stakeholders and create a competitive advantage. Obtaining and fostering an engaged and talented team that has the knowledge, training, skills and experience to deliver on our strategic objectives is vital to our success. We must attract, integrate and retain the talent we need at all levels of the business.	Ÿ We have identified the core capabilities that align with our strategic ambition and continue to develop our Academy to help develop the right skills for the future (see page 40). Ÿ We are involved in a number of initiatives to help secure the future engineering talent required (see page 40). Ÿ We continue to develop our succession plans for key roles, including leadership. Ÿ We have described on page 41 some of the ways we seek to engage employees, including how we promote inclusion and diversity. Ÿ We monitor employee engagement and formally solicit employee opinions via a Company-wide employee survey annually.

Strategic objective	Risk description	Example of mitigations
Deliver operational excellence	Failure to achieve levels of financial performance required to meet regulatory requirements. The Group operates under a number of regulatory regimes and we must maintain the performance levels required. Failure to achieve the agreed returns could damage our reputation and threaten future growth opportunities and regulatory arrangements.	Ÿ We have a US strategy focused on safety and reliability, customer responsiveness, stewardship and cost competitiveness. Performance measures are tracked and reported monthly. US jurisdictional presidents continue to develop strong relationships with local regulators and communities. A process excellence initiative was launched to deliver sustainable and innovative performance improvements with initial focus on six core end-to-end processes. Ÿ The UK operating model implemented in 2013 to support our performance under RIIO is now established and we continue to roll out our performance excellence framework across the business. Ÿ We monitor network reliability and customer satisfaction as KPIs, as described on page 10.

	Failure to deliver appropriate information systems and data integrity. The Company is increasingly reliant on technology to support and maintain our business-critical processes. We must be able to rely on the performance of these systems and the underlying data to demonstrate the value of our business to our shareholders, and to meet our obligations under our regulatory agreements, and comply with agreements with bond holders and other providers of finance.	Ÿ In November 2012, our new US back office system went live. A business improvement team has been established to ensure that a comprehensive and integrated approach is applied to the execution of system changes (such as enablement of the LIPA MSA transition) and enhancements to drive business value (such as payroll, supply chain and finance process improvements). Ÿ We are undertaking a programme to strengthen identified weaknesses in US controls over financial reporting. Ÿ We are implementing a global information management framework focusing on data integrity and security. Ÿ We have completed a data assurance programme, and we are developing actions to improve our data quality and integrity processes based on the results.

	We experience a catastrophic/major cyber security breach. Due to the nature of our business we recognise that our critical national infrastructure systems may be a potential target for cyber threats. We must protect our business assets and infrastructure and be prepared for any malicious attack.	Ÿ We use industry best practices as part of our cyber security policies, processes and technologies. Ÿ We continually invest in cyber strategies that are commensurate with the changing nature of the security landscape. This includes collaborative working with DECC and the Centre for Protection of National Infrastructure (CPNI) on key cyber risks and development of an enhanced critical national infrastructure (CNI) security strategy and our involvement in the US with developing the National Institute of Standards and Technology (NIST) Cyberspace Security Framework.

	Failure to prevent a significant process safety event. The nature of our day-to-day operations is such that safety incidents can occur. The safety of our employees, contractors, suppliers, and the communities in which we operate is critical. We must operate within local laws and regulations relating to health, safety and the environment.	Ÿ We have established safety and occupational health plans, programmes and procedures that are aimed at continuous improvements in safety performance. Ÿ We supplement Company-wide initiatives with specific regional safety programmes. These are aimed at addressing specific areas so that safety is at the forefront of every employee’s mind. We also benchmark against other industry groups to seek and implement best practice. Ÿ We continue to focus on process safety, aimed at preventing major incidents. A baseline assessment has been completed and a 10 year plan is under development. Ÿ We monitor employee IFR as a KPI as described on page 10.

They are also the basis of our compliance with obligations set by the Sarbanes-Oxley Act 2002 and other internal assurance activities. Internal control over financial reporting We have specific internal mechanisms to govern the financial reporting process and the preparation of the Annual Report and Accounts. Our financial controls guidance sets out the fundamentals of internal control over financial reporting, which are applied across the Company. Our financial processes include a range of system, transactional and management oversight controls. In addition, our businesses prepare detailed monthly management reports that include analysis of their results along with comparisons to relevant budgets, forecasts and prior year results. These are presented to and reviewed by senior management within our Finance function.						These reviews are supplemented by quarterly performance reviews, attended by the Chief Executive and Finance Director which consider historical results and expected future performance and involve senior management from both operational and financial areas of the business. Each month the Finance Director presents a consolidated financial report to the Board. As part of our assessment of financial controls, we have identified a number of weaknesses in our US financial control framework. Plans are in place to remediate these. For more information, including our opinion on internal control over financial reporting, see page 170.

Our strategy

To be a recognised leader in the development and operation of safe, reliable and sustainable energy infrastructure, to meet the needs of our customers and communities and to generate value for our investors.

Our strategic objectives

The Committee believes that the changes will further enhance the long-term alignment between executive remuneration and the delivery of the corporate strategy.

The information set out below describes current rather than future policy.

Alignment to strategy

Annual Performance Plan (APP)

Our APP aims to incentivise and reward the achievement of annual financial and strategic business measures, and the delivery of annual individual objectives. Performance metrics, including corporate financial measures and individual objectives, are agreed at the start of each performance year and are aligned with the strategic business priorities for that year.

The table below shows the financial measures and their relative weightings that were included within the APP for the Executive Directors for 2013/14:

Financial measures together represent 70% of the APP.

Individual performance objectives in the APP reflect 30% of the plan and are defined in terms of target and stretch performance requirements. The performance objectives change each year, depending upon business priorities. Examples of individual objectives include those relating to safety, stakeholder relations, employee engagement and capability, and the development of Group and financial strategy.

In order to provide balance for all our stakeholders, at the end of the year the Remuneration Committee has discretion to reduce APP awards to take account of any safety, customer, service-related, environmental or governance issues that may have occurred.

The Remuneration Committee aligns the remuneration policy to our Company strategy and main business objectives. Performance-based incentives are earned through achieving demanding targets for short-term business and individual performance, as well as creating long-term value for our shareholders, customers and the communities in which we operate.

Remuneration Committee review

of remuneration

During the year, the Remuneration Committee undertook a detailed review of the remuneration arrangements for Executive Directors, with the aim of achieving further alignment between executive reward and long-term shareholder value.

As a result of this review, the Committee is proposing some significant changes to the arrangements for the 2014/15 financial year, and these are set out in detail on pages 58 to 73. Shareholders are being asked to approve these changes at the AGM on 28 July 2014.

		Overview of our UK RIIO-regulated businesses during 2013/14
		Over the past year there have been significant regulatory changes in the UK, most notably the introduction of RIIO and its associated incentives. The RIIO regulatory framework, which began on 1 April 2013, incentivises us to operate efficiently. It also provides opportunities in terms of specific incentives to engage and serve our customers and stakeholders well. There have been significant Government and regulatory policy changes affecting our business, including the introduction of EMR and the evolution of the system operator role in the long-term planning of the network. Also, with a likely tightening of the margin between electricity supply and demand in the mid to late part of the decade, additional tools have been developed to help us balance the electricity transmission system. The planning process for obtaining consent for major infrastructure projects has also changed, requiring significant consultation before an application to the Planning Inspectorate. Our Kings Lynn B connection project was the first to go through the new process and was granted consent by the Secretary of State in December 2013. Progress during 2013/14 Our activities and achievements in the UK during 2013/14 have included: • Achieving an employee injury frequency rate of 0.06, meeting our target of world-class performance. Initiatives during 2013/14 included a visible safety leadership programme with a renewed focus on behavioural safety and excellent role modelling, as well as introducing best practice incident analysis tools and systems from the US into our UK business so we can improve how we learn from incidents. • Making significant progress on the implementation of our new UK operating model by concluding the managerial and staff appointment process in our Transmission business. • Working with trade unions to agree revisions to pay and terms and conditions for employees. We have also agreed changes to our UK pension arrangements for all employees who have defined benefit (DB) or defined contribution (DC) schemes. These changes aim to make sure our total reward package remains both competitive in the market and sustainable under RIIO. • Working on the 2013 triennial valuations of our two DB pension plans (for further information see note 29 under ‘Notes to the consolidated financial statements’). • Maintaining resilient networks during the wettest winter on record. Our networks withstood the winter storms well, when some electricity distribution networks had significant issues. We have installed extra flood protection at critical UK sites, helping maintain reliability and reduce				costs. Following the severe wet weather over Christmas 2013 we have been working on future potential network resilience issues. For details about our reliability performance see page 10. • Renegotiating our key contracts and introduced new contractor relationships so we can deliver our RIIO outputs efficiently and provide clarity on the accountability for safety between ourselves and our contractors. • Continuing to focus on delivering excellent levels of service. 2013/14 has been the first year in which we have had incentives for customer and stakeholder satisfaction for our regulated businesses. Ofgem set a baseline target of 6.9 for customer and stakeholder satisfaction for our regulated transmission businesses with scoring ranging from 1 – very dissatisfied to 10 – very satisfied. We have performed well in our customer surveys, scoring 7.2 for our Gas Transmission business and 7.4 for our Electricity Transmission business. The stakeholder surveys are newly introduced but early indications are that both transmission businesses are in line to achieve good results for stakeholder satisfaction. • Under RIIO our gas distribution customer satisfaction results are now reported on an annual basis, rather than quarterly, which was how we reported them under our previous price control. We will publish the results on our website in the summer as part of our commitment to our stakeholders, and in our Annual Report and Accounts for 2014/15. • Extensive involvement in the development of new network codes to underpin the European internal energy market. • Focusing on changing our ways of working – supporting the development of our global performance excellence framework with targeted roll-out in the UK. Our approach has been to build up the capability requirements through early adopters before starting the full-scale roll-out over the coming months. Principal risks Our regional risk profile describes the main risks our UK business faces. Below, we provide an overview of some of the risk themes we are managing: • the risk of changes to the complex political and regulatory agenda for UK and European energy policy development and their potential implications for our business; • challenges associated with making sure the data required to deliver business processes and regulatory requirements is complete, accurate and consistent; • the impact of changes in our business structure and processes on our ability to continue to perform under RIIO; and • continued management of safety, security and network resilience.

UK Electricity Transmission
What we do We own the electricity transmission system in England and Wales. Our networks comprise approximately 7,200 kilometres (4,470 miles) of overhead line, 1,400 kilometres (870 miles) of underground cable and 335 substations. We are also the national electricity transmission system operator, responsible for both the England and Wales transmission system, and the two high voltage transmission networks in Scotland, which we do not own. Day-to-day operation of the system involves the continuous real-time matching of demand and generation output. We are also designated as system operator for the new offshore electricity transmission regime. Where we are heading Although demand for electricity is generally increasing around the world, in the UK it is expected to remain broadly flat over the next five to 10 years. Changes in the sources and characteristics of generation connecting to our network mean we need to develop the way we balance and operate our network to accommodate these sources, including wind, new and large-scale nuclear generation, and many embedded sources that are connected to local networks and not our transmission grid. Industry forecasts indicate there will be a tightening of the margin between the available supply of electricity and the demand for it over the next few years. We have a central role in developing the reform of the electricity market, which is designed to incentivise new generation to be built. We have also developed two new balancing services allowing the market to provide us with additional tools to balance the network if required. Over the last 12 months some generators have delayed their connection dates to the network and this means our future investment profile for electricity transmission is flatter than in previous years. But we are ready to respond to connection dates when we need to. We will continue to renew our network to deliver the network reliability our customers require as efficiently as possible. What we’ve achieved during 2013/14 • We made significant progress with our network upgrade plans. We are pleased with our progress on the London Power Tunnels project and have now started site works on the first 600 kV subsea HVDC link in the world. Connecting Scotland and England, this link will support the export of low carbon Scottish generation. • In March 2014, the new Transmission National Control Centre in Warwick became operational. This will help our focus on the future complexities of network security, energy management and streamlining our operational and safety switching	activities, increasing the potential for access to the transmission system. • We improved our asset maintenance policy, which will provide greater efficiency for our maintenance programme. We are implementing the policy throughout 2014 to minimise disruption to customers and planned work. • We worked closely with DECC and Ofgem to help inform and manage security of supply through a period of significant change in the UK energy market. • We have carried out analysis to help inform the Government’s decisions on energy policy as well as administering key parts of the enduring regime. • We have developed two new balancing services that could be used to provide additional reserves to support the operation of the electricity transmission system if margins continue to tighten towards the middle of this decade. These new services, known as the Demand Side Balancing Reserve and the Supplemental Balancing Reserve, were approved by Ofgem in December 2013, and the associated funding arrangements approved in April 2014. We will tender for these services if they are needed for the forthcoming winters. Priorities for the year ahead • Work with our contract partners to continue improving safety performance. • Engage with customers and stakeholders while we progress our major infrastructure projects through the planning process. • Continue the roll-out of our new performance excellence way of working across Electricity Transmission. • Develop new, innovative ways to deliver the network reliability our customers require, at minimum cost. • Build on the analysis results that informed the first EMR delivery plan and successfully implement and operate the Capacity Market and Contracts for Difference Feed-in Tariff regime, as part of the Government’s EMR project. This will support a sustainable, affordable and secure electricity market into the future, in addition to the procurement of balancing services to support mid-decade capacity margins. • Shape development in the UK and EU energy industry by continuing the development of network codes to support the completion of a European Internal Energy Market in 2014.	30% UK Electricity Transmission adjusted operating profit of Group total

UK Gas Transmission
What we do We own and operate the gas national transmission system in Great Britain, with day-to-day responsibility for balancing demand. Our network comprises approximately 7,660 kilometres (4,760 miles) of high pressure pipe and 23 compressor stations. Where we are heading The UK’s sources of gas are changing – as gas from the UK continental shelf is being depleted, we are becoming increasingly reliant on imports from Europe and elsewhere. This also means that the traditional flow of gas from the North to the South is changing. To ensure we continue delivering a safe, reliable and secure gas supply as we develop our asset replacement programmes, we need to make sure we consider the future operational needs of the network. We will continue to work closely with our customers and stakeholders to adapt our network and our services so we can meet their needs economically and efficiently. What we’ve achieved in 2013/14 • We delivered our strongest-ever safety performance across all areas, achieving 12 months without a single lost time injury to either our employees or contractors and without experiencing any serious process safety incidents. • We delivered multiple innovation projects using the Network Innovation Allowance funding mechanism, including 3D models that allow for more efficient and cost-effective construction. • We have adapted our ways of working so we can meet the needs of our customers and stakeholders and deliver value under RIIO. For example, we used innovative techniques to protect a section of the pipeline that carries gas from the LNG importation terminal in west Wales, prior to the construction of a new road. This meant we were able to meet the timescales of the local authority building the road without disrupting gas supply to consumers. • We have delivered record levels of compressor availability in our network, peaking at 98%, after investing in our fleet of compressors in the summer of 2013 and by introducing improvements to our maintenance and repair methods.	Priorities for the year ahead • Continue to improve safety performance by completing the roll-out of the visual safety leadership culture programme to every employee in our Gas Transmission business and implementing new ‘safe control of operations’ working procedures. • Work with our customers and stakeholders to develop an enduring compressor replacement strategy that makes sure we comply with environmental legislation and meets future system needs. • Complete the deployment of our new performance excellence way of working across all teams in our Gas Transmission business after the successful implementation at two of our compressor sites in 2013/14. • Support our customers in the transition to new commercial frameworks managing future capacity and connection arrangements to the gas transmission system. • Shape developments in the UK and EU energy market by making sure that the new European codes governing the operation of the gas market in the UK are successfully introduced for our customers.	11% UK Gas Transmission adjusted operating profit of Group total

UK Gas Distribution
We own and operate four of the eight regional gas distribution networks in Great Britain. Our networks comprise approximately 131,000 kilometres (81,000 miles) of gas distribution pipeline and we transport gas from the gas national transmission system to around 10.9 million consumers on behalf of 32 gas shippers. Gas consumption in our UK networks was 264 TWh in 2013/14 compared with 306 TWh in 2012/13. We manage the national gas emergency number (0800 111 999). This service, along with the enquiries lines, appliance repair helpline and meter enquiry service, handled nearly 2.5 million calls during 2013/14. Where we are heading We have articulated an ambition for 2017 – to be the best gas distribution business in Britain. We are using modern technology and new, innovative techniques to develop gas networks that are fit for the future, safe and secure, keeping people warm. Our regulator is able to make direct comparisons between the performance of our four gas distribution networks, and others. Customer expectations are increasing across all industries and we are responding by focusing more effort than ever before on providing a good-quality service at an affordable price to all our customers and stakeholders. We will do this by carrying out our works in the most efficient way possible.	• A notable example of innovation during 2013/14 has been the use of a repair robot called CISBOT to fix a leaking 18 inch gas main in London. This was the first time in Great Britain that an 18 inch gas main has been fixed by robots. This kind of automation reduces traffic disruption and avoids the need to shut off the gas while doing the repair work, making life easier for people. • Working with Future Biogas we successfully commissioned the first commercial biogas-to-grid project in Doncaster. The biomethane injection is produced from a maize feedstock and is the first of 20 similar projects that we are committed to connect during 2014/15. This kind of project promotes the future role of gas in the transition to a low carbon economy and is also the first of 80 connections we expect to complete over the RIIO period. Priorities for the year ahead All our priorities support our Gas Distribution ambition and are above and beyond meeting our standards. • Achieve our safest year ever by improving the safety to members of the public, continuing to reduce cable strikes and making improvements that will help reduce the number of third-party encroachments. • Improve the experience our customers have with us and the way in which we engage with our stakeholders, including reducing complaints and rejuvenating our customer connections process. • Invest in our people to help them develop their skills and increase their capability, including a focus on the role of the supervisor and promoting accelerated development assignments. • Engage with our people by embedding performance excellence in the remainder of our Gas Distribution business and delivering on our enhanced engagement strategy. • Drive innovation so we can improve the services and value we provide to our customers by both maximising existing technology and identifying new opportunities for future development. • Improve the quality and availability of our data and management information so we can operate more efficiently in the future.	25% UK Gas Distribution adjusted operating profit of Group total
What we’ve achieved during 2013/14
• We have improved our overall safety performance (see page 10). We have focused on reducing cable strikes with programmes like ‘dial before you dig’ and seen a 14% reduction in cable strikes during 2013/14. • The number of customer complaints we received during 2013/14 was 13.3% less than the previous year. However, we know our customers want more and we are focusing our attention on improving even further, particularly the experience customers have when they want to connect to our network. • Last year we listened to what our stakeholders had to say through our consultation process and we made 29 commitments to improve in areas of stakeholder priority such as fuel poverty, vulnerability, gas safety – including carbon monoxide awareness – and new and innovative ways of working. • We have been simplifying and improving the way we work so that our employees can be as effective as possible and our customers get a service they value. We are doing this by looking for ways to streamline, innovate and improve everyday working practices with our business and our strategic partners who help us reach our goals.

US Regulated business
What we do We own and operate electricity distribution networks in upstate New York, Massachusetts, and Rhode Island. Through these networks we serve approximately 3.4 million electricity consumers in New England and upstate New York. Our US gas distribution networks provide services to around 3.6 million consumers across the northeastern US, located in service territories in upstate New York, New York City, Long Island, Massachusetts and Rhode Island. We added 31,145 new gas heating customers in these areas in 2013/14. We own and operate an electricity transmission system of approximately 14,328 kilometres (8,903 miles) spanning upstate New York, Massachusetts, Rhode Island, New Hampshire and Vermont, operating 169 kilometres (105 miles) of underground cable and 521 substations, with a further 12 planned. We also own and operate 50 fossil fuel-powered units on Long Island that together provide approximately 3,800 MW of power under contract to LIPA. A 15 year Power Supply Agreement (PSA) with LIPA was renewed in May 2013 for 3,634 MW of capacity, comprising eight dual fuel (gas/oil-fired) steam units at three sites, 11 dual fuel combustion turbine units, and 27 oil-fired combustion turbine/ diesel units. Under a separate contract with LIPA, four dual fuel combustion turbine units provide an additional 160 MW of capacity. We are responsible for billing, customer service and supply services. We forecast, plan for and procure approximately 15 billion standard cubic metres of gas and 32 TWh of electricity annually across three states. Where we are heading We have introduced Connect21, our thinking on advancing America’s natural gas and electricity infrastructure beyond its 20th century limitations, and creating a more customer-centric, resilient, agile, efficient and environmentally sound energy network. Our approach is threefold: — Build a resilient backbone for our energy system that can provide reliable, flexible electric and gas service to all customers and integrate clean energy wherever it is located on the grid. — Inform customers about choices available to them to meet their energy needs and educate them on how to manage their use in the most cost-effective way. — Offer customised solutions to customers who want different levels of service.	Connect21 will help develop America’s economic and environmental health in three very important ways: — Drive economic growth: invest in our networks in ways that enhance state and local economies and encourage innovation, while simultaneously reducing the stress currently being exerted on our environment and public health. — Promote cleaner energy: work with the industry to find new ways to deliver cleaner energy, and more importantly encourage consumers to use energy more efficiently. We are already making progress on cleaner sources of energy, such as natural gas. The amount of energy generated by natural gas in the US is expected to double between 1990 and 2040, making gas the leading fuel for electricity generation. — Advance innovative technologies: harness existing technologies to put energy information and usage control in the hands of customers, which will help drive improvements in our consumption behaviours. Leverage technology to build smarter, more resilient electric and natural gas networks that can withstand the extreme weather. Principal risks Our regional risk profile describes the main risks our US business faces. The current risk themes for the US are: — our ability to manage data and systems improvements required to deliver core business processes and regulatory requirements; — our ability to recover costs through existing rate- making mechanisms and to influence the development of the future US utility business model; and — safety performance and network reliability, security and resilience. What we’ve achieved Within each of our jurisdictions we have focused on Elevate 2015, our journey towards operational excellence. This focus has encompassed our end-to-end business processes, including: — delivery; — maintenance and operation of electric and gas assets; — supply chain management; — meter to cash; and — emergency response. Four main principles govern our business improvement strategy: safety and reliability; stewardship; customer responsiveness; and cost competitiveness.	31% US Regulated business adjusted operating profit of Group total

All jurisdictions have benefited from emergency response improvements. This has been a focus for the US business in response to the major storms we have experienced in recent years, such as Superstorm Sandy in 2012. Our Emergency Management Policy reinforces our commitment to our customers and the communities we serve. We strive to use effective emergency management principles and protocols that enhance our ability to provide safe and reliable energy services.

We have continued to strengthen resilience by assessing vulnerabilities throughout our system, flood-proofing critical equipment, readying more restoration crews, repair equipment and fuel supplies, reducing the risk of downed power lines from fallen trees and branches, and enhancing communications with our customers and stakeholders. During 2013/14 we introduced some new tools and initiatives:

— Weather predictive tool: allows us to use data from

past storm events to learn and predict future

potential damage, which will help our storm

response planning.

— Expanded contractor relationships: expanding

contractor relationships that cover a wider

geographic area to increase flexibility and

responsiveness in any type of storm.

— Enhanced damage assessment: by using

technology now available to us (mobile devices such

as tablets) we have introduced an enhanced

damage assessment process that helps us to gather

information from the field more quickly. Coupled with

data from existing outage reporting systems, this

allows us to determine where to send crews more

quickly and accurately. This, in turn, will help us to

determine and execute restoration times faster for

customers and communities.

Overall, the business remains on track to successfully conclude the programme during 2014, with expected costs unchanged from the guidance provided last year.

Safety: we continue to make improvements on last year, including decreases in OSHA recordable incidents, road traffic collisions and lost time incidents. Still, we have much to accomplish to

reach our goal of zero injuries every day. Some of our initiatives during 2013/14 include the development and implementation of a safe motor vehicle operation policy, Smith System driver training, a soft tissue injury prevention programme, and slippery surface simulator training. Also, in a continued effort to promote safety awareness and improvement, we have shared incident reports and lessons learned briefings with all employees, on a daily basis.

Network reliability: we met all our reliability targets in Rhode Island and New York. In Massachusetts, we missed two of our electricity circuit level metrics and avoided a financial penalty due to earned offsets for good performance on our system metrics.

Customer satisfaction: we use independent customer research studies and other measures to supplement the four J.D. Power and Associates customer satisfaction studies. We saw improvements in three of the four overall J.D. Power customer satisfaction quartile results – see page 10 for details.

In terms of our achievements during 2013/14, here are some highlights from each of our jurisdictions:

Massachusetts

Infrastructure investment: we invested $510 million to enhance the resilience, efficiency and safety of our infrastructure – $212 million in electric and $298 million in natural gas.

Energy efficiency: we introduced ‘Smart Energy Solutions’, a programme rolled out to 15,000 customers. The programme uses grid modernisation solutions, including advanced meters and communications systems and offers our customers better data about their energy usage, which helps them to make more informed decisions.

Gas expansion: we installed 32 miles of new gas mains, replaced 162 miles of gas mains and added more than 9,700 new natural gas customers.

National Grid teams maintain and repair the gas distribution networks across Rhode Island, where we deliver gas to 252,000 customers. The team in this picture is creating a solid base to reinstate the ground after some works on Rhode Island’s gas network.

Economic development: we installed 15 miles of new electric circuit in Cape Ann, and reconfigured existing circuits to release additional capacity (more than $15 million investment).

New York

Infrastructure investment: we invested $1,008 million to enhance the resilience, efficiency and safety of our infrastructure – $471 million in electric and $537 million in natural gas. In partnership with the New York City Department of Environmental Protection, we launched the Newtown Creek Renewable Gas Demonstration project in Brooklyn. As part of our commitment to sustainable energy solutions, Newtown Creek is the first project in the US that directly injects renewable gas into a local distribution system by converting effluent from a wastewater treatment plant into biogas.

Energy efficiency: we are working with 13 institutions and 50 public and private companies within the Buffalo Niagara Medical Campus to enhance power quality and reliability, as well as address other energy and transportation challenges related to the expansion and development of the campus.

Gas expansion: we completed the largest oil to natural gas conversion on Long Island, saving the Northport VA Hospital nearly $3 million a year, displacing 1.5 million gallons of oil annually, and reducing carbon emissions by more than 5,000 tonnes a year.

Economic development: we provided the State University of New York at Canton (SUNY Canton) with a $750,000 Renewable Energy and Economic Development incentive to help with the completion of an on-campus wind turbine project.

Clean Line energy investment: Clean Line Energy Partners is developing several long-haul HVDC transmission lines to connect the best renewable energy resources to communities. Five projects are currently in development which span across states in the Midwest and Southwest US. We are an equity partner in these projects and the first utility to invest with Clean Line.

DeepWater Wind: the 30 MW DeepWater Offshore Wind Farm, located off the coast of Block Island, Rhode Island is in development and could become the first offshore wind farm in the US.

We are designing and constructing the approximately 20 mile submarine transmission cable from Narragansett, Rhode Island to Block Island, Rhode Island. The transmission cable will allow the energy generated by the wind farm to access the mainland Rhode Island customers and connect Block Island Power Company (BIPCo), which will become a new wholesale customer of National Grid, to the mainland electric system. While the wind farm will provide Rhode Island customers with a sustainable source of generation, the transmission cable will allow BIPCo to reduce its dependence on diesel generation which will result in significantly lower energy prices and emissions for the residents of Block Island.

Priorities for the year ahead

National Grid US field operations crew leader Mark Harris.

Energy efficiency: Rhode Island energy efficiency programmes will result in savings of more than 1.6 million MWh of electricity and 4.37 million Dth of natural gas over the lifetime of installed measures. The resulting reduction in carbon emissions is equivalent to taking more than 186,700 motor vehicles off the road for one year.

Gas expansion: the Rhode Island Public Utilities Commission (RIPUC) approved a $3 million gas expansion pilot programme to be included in the FY2014 Gas Infrastructure, Safety and Reliability (ISR) Plan.

Economic development: energy efficiency programmes resulted in more than 540 full-time equivalent jobs and should generate economic benefits of more than $237 million over the life of the installed measures (with more than $190 million from

The interconnector is approximately 70 kilometres (43 miles) in length, with 45 kilometres (27 miles) of subsea cable. Following a significant valve replacement programme, the availability of the interconnector continues to show marked improvement and the 2013/14 average was at 83.84%. A substantial proportion of the flow continues to be in the import direction, from France to Great Britain. BritNed is a joint venture between National Grid and TenneT, the Dutch transmission system operator. It built, and now owns and operates a 1,000 MW subsea electricity link between the UK and the Netherlands, which is approximately 260 kilometres (162 miles) in length. BritNed, which entered commercial operations on 1 April 2011, is a merchant interconnector that sells its capacity via a range of explicit and implicit auction products. Metering National Grid Metering (NGM) provides installation and maintenance services to energy suppliers in the regulated market in Great Britain. It maintains an asset base of around 15 million domestic, industrial and commercial meters. Through Ofgem’s Review of Metering Arrangements, National Grid has been appointed National Metering Manager (NMM) to facilitate the transition to smart metering in the domestic sector. To support this, NGM has also undertaken a pricing consultation to define the tariff caps to apply to traditional domestic gas metering. This took effect on 1 April 2014 and will last until the end of the transition to smart metering. In addition, NGM has been further developing its contracts and services in the industrial and commercial market. NGM has achieved its highest customer satisfaction scores for the last six years for both its Domestic and Industrial & Commercial businesses.	UK Property National Grid Property is responsible in the UK for the management, clean-up and disposal of surplus sites, most of which are former gas works. During 2013/14 we have sold 45 sites, exchanged on several high-profile land disposal agreements with JV partners and embarked on a new programme of holder demolitions. We have been embedding our estate management outsourcing agreement with Capita and our new tender framework for the clean-up of contaminated land is progressing well. Xoserve Xoserve delivers transactional services on behalf of all the major gas network transportation companies in Great Britain, including National Grid. Xoserve is jointly owned by National Grid, as majority shareholder, and the other gas distribution network companies. US non-regulated businesses Some of our US businesses are not subject to state or federal rate-making authority. These include interests in some of our LNG road transportation, some gas transmission pipelines and certain commercial services relating to solar installations, fuel cells and other new technologies.

Volunteering

Our employees continue to support our local communities, sharing their time and expertise on a range of skills-based volunteering and fundraising activities. This year in the UK we continued supporting Special Olympics GB by sponsoring the National Summer Games, launched our first-ever employee chosen charity partnership with Macmillan Cancer Support and joined forces with two initiatives – Step up to Serve and TeachFirst.

In the US, our Power to Serve programme is evolving as we focus on volunteering efforts that make National Grid a great place to work, and our communities great places to live. Power to Serve supports our Elevate 2015 Stewardship principle and seeks to acknowledge existing community service, as well as to create new volunteer opportunities for employees.

Health and wellbeing

Our health and wellbeing programmes for 2013/14 have included encouraging employees to improve their levels of activity and quality of nutrition, as well as supporting employees’ mental wellbeing and musculoskeletal conditions. With our major cancer charities (Macmillan Cancer Support in the UK and The American Cancer Society in the US) we have raised money and awareness. Our employee opinion survey results continue to show that employees have a growing awareness of our wellbeing programmes.

Promoting an inclusive and diverse workforce

We aim to develop and operate our business with an inclusive and diverse culture, with equal opportunity to all in recruitment, career development, training and reward. This applies to all employees regardless of race, gender, nationality, age, disability, sexual orientation, gender identity, religion and background. Where existing employees become disabled, our policy is to provide continued employment and training wherever practical. Our policies support the attraction and retention of the best people, improve effectiveness, deliver superior performance and enhance our success.

During 2013/14, Race for Opportunity and Opportunity Now each awarded us with their Gold standard and recognised us as one of the top 10 private sector employers in terms of their benchmark criteria. We were also once again selected as one of the Times Top 50 Employers for Women.


In the US, we have focused on boosting membership and awareness of our Employee Resource Groups, which have measurable goals that are in line with our vision and Elevate 2015 ambitions. These groups aim to build awareness and understanding of inclusion and diversity throughout the organisation. Their activities include programmes designed to build skills that help manage differences. The table below shows the breakdown by gender at different levels of the organisation. We have included information relating to subsidiary directors, as this is required by the Companies Act 2006 (Strategic Report and Directors’ Reports) Regulations 2013. We define ‘senior management’ as those managers who are at levels Executive –1 and Executive –2, as well as those who are directors of subsidiaries or who have responsibility for planning, directing or controlling the activities of the Company, or a strategically significant part of the Company, and are employees of the Company.

Human rights National Grid does not have a specific policy relating to human rights, but respect for human rights is incorporated into our employment practices and our values, which include respecting others and valuing diversity. ‘Doing the Right Thing’ is our guide to ethical business conduct. The way in which we conduct ourselves allows us to build trust with the people we work with. We earn this trust by doing things in the right way, building our reputation as an ethical company that our stakeholders want to do business with, and that our employees want to work for. Our procurement policies integrate sustainability into the way we do business throughout our supply chain, so that we create value, preserve natural resources and respect the interests of the communities we serve and from which we procure goods and services. Additionally, through our supplier code of conduct, we expect our suppliers to keep to all laws relating to their business, as well as the principles of the United Nations Global Compact, the United Nations Declaration of Human Rights and the International Labour Organization (ILO).

		Chairman’s foreword An effective Board is vital to the sound foundations of good corporate governance. Our Board has undergone a significant change over the last three years to refresh membership and replace long-serving Non-executive Directors. As part of this planned transition, this year we have welcomed Therese Esperdy and John Pettigrew to our Board and, following the AGM, Maria Richter will be stepping down from the Board. We will also be saying goodbye to Nick Winser, who will not be standing for re-election to the Board at the AGM, but will continue in his role as President of ENTSO-E and Chairman of NGET and NGG until July 2015 when he will be leaving the Company. Through the progressive refresh of the Board we have successfully renewed the membership and key roles to bring a diverse range of skills and experience to our Board. I am pleased to report that the results of the Board evaluation this year were positive, showing that our regenerated Board is functioning well, although there is always room for improvement. See page 46 for examples of the actions we have identified for the coming year. All our new Board members undertake a thorough induction programme to get them up to speed on our businesses. The induction programme is tailored to the new Director to take account of previous experience and their specific role on the Board. I am confident that the programmes designed for Therese and John, which are detailed on page 45, will provide a good basis to enable them both to make a valuable early contribution to our Board. As a Board we continue to support constructive challenge, encourage robust debate and recognise the value of different thinking styles. During the year we held a development session for the Board on ‘thinking styles’, see page 45 for details. It is my strong belief that our ongoing emphasis on a positive and collegiate boardroom environment is helping the dynamics of the relationship between our Executive and Non-executive Directors. Because of this, we are able to increase the individual contribution of Directors and use their diverse backgrounds and expertise in enriching the quality of boardroom debates and discussions. The behaviours and dynamics of the Board will be an ongoing focus for us as we strive to continually improve our effectiveness and performance. Sir Peter Gershon Chairman

	Compliance statement The Board considers that it complied in full with the provisions of the UK Corporate Governance Code 2012 (the Code) during the financial year being reported, see page 51 for our explanation in relation to external audit tendering.	The Board sets the risk appetite for the Company and takes the lead in areas such as safeguarding the reputation of the Company and financial policy, as well as making sure we maintain a sound system of internal control (see page 25). The Board as a whole is responsible for making sure that there is satisfactory dialogue with shareholders. Further details of our investor engagement activities are set out opposite. The Board’s full responsibilities are set out in the matters reserved for the Board, available on our website, together with other documentation relating to the Company’s governance. Examples of Board focus during the year:

This report explains the main features of the Company’s governance structure to give a greater understanding of how the main principles of the Code have been applied. The report also includes items required by the Disclosure and Transparency Rules. The index on page 57 sets out where to find each of the disclosures required in the Directors’ Report together with the Board’s sign-off on the report.
Fair, balanced and understandable
The Board received a paper on the governance arrangements that have been put in place to make sure that the Annual Report and Accounts meet the requirements of the Code. The coordination and review of the Annual Report and Accounts follows a well-established and documented process, which is conducted in parallel with the formal audit process undertaken by the external auditors. The Board considered and endorsed the arrangements in place to enable it to confirm (see page 76) that the Annual Report and Accounts, taken as a whole, is fair, balanced and understandable. Our Board Our Board is set out on the previous page, along with the age, committee membership, independence, and tenure of all members. Their full biographical details are set out on pages 171 to 173. The Directors who were in place during the year are shown on page 48, together with details of Board meeting attendance. Committee membership during the year and attendance at meetings is set out in each of the individual committee reports later in this report.

Examples of expected Board focus for next year:
	Our Chairman is responsible for the leadership and management of the Board and its governance. By promoting a culture of openness and debate, he facilitates the effective contribution of all Directors and helps maintain constructive relations between Executive and Non-executive Directors. Our Chief Executive is responsible for the executive leadership and day-to-day management of the Company, to ensure the delivery of the strategy agreed by the Board. Through his leadership of the Executive Committee, he demonstrates commitment to safety, operational and financial performance.	— annual review of safety activities; — continued detailed review of strategy and financing; — risk appetite discussions; — progress on the stabilisation of the new enterprise resource system and updates on the US Foundation Program; — review of the business performance under RIIO; — outcome of the New York gas audit; — talent review and succession planning; — results and actions from the 2014 employee opinion survey; and — progress against the actions from the 2013/14 Board and committee evaluation.
	Our Senior Independent Director acts as a sounding board for the Chairman and serves as an intermediary for the other Directors, as well as shareholders as required. Independent of management, our Non-executive Directors bring diverse skills and experience, vital to constructive challenge and debate. Exclusively, they form the Audit, Nominations and Remuneration Committees, and have an important role in developing proposals on strategy.	Board composition The successful delivery of our strategy depends upon attracting and retaining the right talent. This starts with having a high-quality Board. Balance is an important requirement for the composition of the Board, not only in terms of the number of Executive and Non-executive Directors, but also in terms of the range of expertise and backgrounds.
Role of our Board		While traditional diversity criteria such as gender and ethnicity are important, we also value diversity of skills, experience and knowledge. You can read about our Board diversity policy in the Nominations Committee report on page 55.
Our Board is collectively responsible for the effective oversight of the Company and its businesses. It also determines the strategic direction and governance structure that will help achieve the

Individual shareholders

Engagement with individual shareholders, who represent more than 95% of the total number of shareholders on our share register, is led by the Group General Counsel & Company Secretary. Shareholders are invited to learn more about the Company through the exhibits at our AGM and the shareholder networking programme.

The shareholder networking programme normally takes place twice a year and includes visits to UK operational sites and presentations by senior managers and employees over two days. If you are a UK resident shareholder and would like to take part, please apply online via the Investors section on our website.

Annual General Meeting

Our AGM will be held on Monday 28 July 2014 at The International Convention Centre in Birmingham and broadcast via our website. The Notice of Meeting for the 2014 AGM, available on our website, sets out in full the resolutions for consideration by shareholders, together with explanatory notes and further information on the Directors standing for election and re-election.

Board and committee evaluation

Following last year’s external review, this year the Board felt it was appropriate to conduct an internal Board and committee evaluation.

The review of the Board was led by Sir Peter. Rather than using structured questionnaires, he asked a number of open questions at one-to-one interviews with each of the Directors in December and January.

The questions were designed to encourage broad discussions on the performance and effectiveness of the Board rather than to assess its procedures. The questions covered areas such as decision making, the quality of Board discussions, the degree of challenge from the Board members, the top concerns of each member and any topics they felt needed additional focus. The discussions also covered the balance between the Board and its committees and the effectiveness of the Board.

The feedback from these meetings formed the basis of the evaluation report from Sir Peter. The findings were presented by Sir Peter to the Nominations Committee in February and then to the Board meeting in March, along with a proposed action plan. The balance between the Board and its committees was felt to be appropriate and no changes in this area were identified. The Board agreed a number of actions for the forthcoming year, as set out below. Progress against these actions will be monitored throughout the year by the Board.

• Decision making – all important matters requiring approval are to be brought to the Board for early input before a decision is needed.

Responsibility: Chairman and Chief Executive

• Board discussions – greater clarity about the scope of Board discussions to be provided in advance and Board members to be encouraged to question if not clear.

Responsibility: Chairman

• Degree of challenge – the Executive Directors to speak to the Chairman about what would make them feel more comfortable to challenge and debate, both with the Non-executive Directors and with their fellow Executive Directors at Board meetings.

Responsibility: Executive Directors

• Board focus – a number of topics were identified that Directors felt needed additional focus by the Board at its meetings, for example cyber risk and the UK political landscape. Ways to improve the focus on each of these were discussed at the March Board meeting and specific actions were agreed and allocated to various Board members.

Responsibility: various Board members

• Effectiveness of the Board – actions to improve Board effectiveness were proposed, for example: continue to improve the quality of Board papers; make sure in-depth items for Board consideration highlight the important issues to be discussed; and encourage reporting from management that incorporates more input from the Executive Directors.

Responsibility: Chairman, Chief Executive and Group General Counsel & Company Secretary, as appropriate

The actions from last year’s externally conducted review were grouped into three themes – mechanics, dynamics and specifics. Progress against the actions agreed by the Board has been monitored through the year and a commentary against each action is set out opposite.

An evaluation of committee performance was also conducted by the chairman of each of the Board committees, as well as the Executive Committee. Each committee concluded that it had operated effectively throughout the year and agreed, where relevant, an action plan to further improve performance. Progress against the action plans will be monitored through the year by the respective committee and the Board.

Non-executive Director independence

The independence of the Non-executive Directors is considered at least annually, along with their character, judgement, commitment and performance on the Board and relevant committees. The Board took into consideration the Code and indicators of potential non-independence, including length of service. A particularly rigorous review was conducted of Maria Richter as she has served for more than six years.

At year-end, all the Non-executive Directors, with the exception of the Chairman, have been determined by the Board to be independent. Tenure is just one indicator of potential non-independence and the experience and knowledge of Maria Richter, who has served on the Board for more than nine years, has been important in facilitating a structured handover and providing continuity during the search for Therese. Maria will not be standing for re-election at the 2014 AGM.

Director performance

At a private meeting of the Non-executive Directors, Mark Williamson, as Senior Independent Director, led a review of Sir Peter’s performance. The review noted that Sir Peter’s commitments had changed during the year following his appointment as non-executive chairman of the Aircraft Carrier Alliance. The time commitment of the new role was carefully considered by the Board and was unanimously approved by the Board prior to Sir Peter accepting the position.

The Non-executive Directors, with input from the Executive Directors, assessed his ability to fulfil his role as Chairman and the arrangements he has in place to fulfil his role, given he is also chairman of a FTSE 250 company. They concluded that Sir Peter’s performance and contribution were first-class and that he demonstrated strong leadership.

The performance of each Director was raised by Sir Peter at his one-to-one meetings conducted for the Board and committee evaluation process.

Following recommendations from the Nominations Committee, the Board considers all Directors continue to be effective, committed to their roles and have sufficient time available to perform their duties. Therefore, in accordance with the Code, all Directors, with the exception of Maria Richter and Nick Winser who will be stepping down from the Board following the conclusion of the AGM, will seek election or re-election at the 2014 AGM as set out in the Notice of Meeting.

How our Board operates The Chairman sets the Board’s agenda in line with its responsibilities and role as set out in the matters reserved for the Board, and the main challenges and opportunities facing the Company, making sure adequate time is available to discuss all items, including strategic issues. To support discussion and decision making, Board and committee members receive papers sufficiently in advance of meetings so that they can prepare for and consider agenda items. Additionally, the Chairman holds a short meeting with the Non-executive Directors before and after each Board meeting to discuss the focus of the upcoming meeting and afterwards to share feedback and discuss any outstanding matters. A one-page executive summary for non-standard papers provides information and clarity around the contribution or action required. Where appropriate, subject matter experts give presentations and provide the opportunity for Directors to ask questions. Board membership and attendance Board membership and attendance at meetings are set out below. Attendance is expressed as the number of meetings attended out of the number possible or applicable for the individual Director during the year to 31 March 2014. Committee membership during the year and attendance at meetings is set out in each of the individual committee reports later in this report.		Instances of non-attendance during the year at Board and committee meetings were determined to be reasonable due to the individual circumstances. Should any Director not be able to attend a Board or committee meeting, the Chairman and committee chairman are informed and the absent Director is requested to communicate opinions and comments on the matters to be considered. Our Board and its committees The Board delegates authority to its committees to carry out certain tasks on its behalf, so that it can operate efficiently and give the right level of attention and consideration to relevant matters. The role and responsibilities of the committees are set out in their terms of reference, available on our website. The committee structure and delegation and reporting lines are set out in the diagram below. In addition to the vertical lines of responsibility and reporting, the committees communicate and work together where required. For example, on some risk matters the Safety, Environment and Health (SEH) Committee collaborates with the Audit Committee. These lines of communication are shown in the diagram below. Committee agendas and schedules of items to be discussed at future meetings are prepared in line with the terms of reference of each committee. At committee meetings, items are discussed and, as appropriate, matters are endorsed, approved or recommended to the Board by the committee. The chairman of each committee provides the Board with a summary of the main decisions and discussion points so the non-committee members are kept up to date. Below the Board committees are a number of management committees, including the Executive Committee. The Executive Committee has responsibility for making management and operational decisions about the day-to-day running of the Company. Further information on some of the management committees, including the membership and operation of the Executive Committee, is set out on pages 56 and 57. Reports from each of the Board committees together with details of their activities during the year, are set out on the following pages.

Audit Committee

Role

Oversees the Company’s financial reporting, and internal controls and their effectiveness, together with the procedures for identifying, assessing and reporting risks. It also oversees the services provided by the external auditors and their remuneration.

Review of the year

My first eight months as chairman have been busy but enjoyable. Last July we said goodbye to George Rose and this July Maria Richter will be stepping down from the Board. I would like to thank them both for their contribution to the Committee. In particular to George for his guidance and support during his handover to me.

As a committee we have held six meetings during the year, two of which were held in the US, providing all members with the opportunity to meet our US teams. Following last year’s committee performance evaluation, we now also meet privately after some of our longer meetings. We use this time to review the meeting and discuss how we can evolve and make our meetings more effective.

The Committee’s main focus has been the US finance function and ongoing improvement of the new enterprise resource system. The Committee has received regular reports throughout the year from the Finance Director and US Chief Financial Officer.

The UK finance team has provided valuable support to the US team and I visited the US with the Finance Director and Group Financial Controller in January to review progress and priorities for 2014. The work on stabilisation of the systems also coincided with the LIPA MSA transition. This was an important milestone in the overall US financial control program.

With the start of RIIO, the Committee received a paper from the UK finance team on the accounting implications of this new arrangement and its impact on the financial control environment. We also reviewed the disclosures within this Annual Report to ensure they provide a fair, balanced and understandable view in the context of current accounting standards.

Next year is also looking busy with an ongoing focus on the enterprise resource system and continual improvement in processes and controls around these systems.

Financial reporting

The Committee monitors the integrity of the Company’s financial information and other formal documents relating to its financial performance. It makes appropriate recommendations to the Board before publication.

An important factor in the integrity of financial statements is making sure that suitable and compliant accounting policies are adopted and applied consistently on a year-on-year basis and across the Company. In this respect, the Committee also considered the estimates and judgements made by management when accounting for non-standard transactions, the treatment of exceptional items and in provision calculations.

These considerations are supported by input from other assurance providers such as the group controls, risk management and ethics and compliance teams, business separation compliance officer, internal (corporate) audit and the SEH Committee, as well as our external auditors. In addition, the Committee also considers reports of the Disclosure Committee. See page 57 for more information.

The Committee reviews and approves the external audit plan annually (see Audit quality below) and, as part of this, considers the significant risks upon which the external auditors will focus their year-end audit. The independent auditors’ report (pages 77 to 80) highlights these risks, some of which led to significant issues that the Committee discussed during the year. These were:

— US financial controls program (including quality of reconciliation

process, US plant accounting and user access controls);

— LIPA MSA transition contract accounting; and

— presentation of exceptional items.

Other risks, including the accuracy and valuation of treasury derivative transactions, and management override of internal control, were not considered in detail by the Committee during the year as nothing significant arose that warranted Committee attention.

Summarised below are the issues that attracted the most focus, and time, of the Committee in relation to the financial statements during the year.

US financial controls program: the primary focus of the Committee during the year has been the work to make sure of the integrity of the new financial system in the US. This included the measures taken to remediate US financial control deficiencies and those highlighted as a result of the implementation of the new enterprise resource system.

Over the course of the year, the Committee requested and reviewed a number of reports in order to understand the detail of the issues. These issues include the timeliness and quality of certain balance sheet account reconciliations, and the process and systems to ensure appropriate capitalisation of labour costs.

The Committee has also challenged and reviewed management’s remediation plans and the design of compensating controls, including enhanced analytical reviews to make sure the Company maintains an effective internal control environment over financial reporting.

Given the significance of this work, Mark Williamson visited the US and held detailed meetings with senior management in January 2014 to confirm remediation plans were progressing as expected.

LIPA MSA transition contract accounting: on 31 December 2013, our US business moved the MSA with LIPA to a third party. This transition was particularly complex. It involved many areas of our US business and required us to manage the transition of more than 2,000 employees, including more than 40 finance

professionals, as well as to provide a new enterprise resource system to LIPA.

The Committee reviewed the accounting treatment of costs incurred as part of the transition and agreed that the judgements made by management were reasonable.

Presentation of exceptional items: at the half year and year end, the Committee discussed and challenged a detailed analysis of items to be classified as exceptional to make sure the items did not include income or costs relating to the underlying business.

In particular, the Committee considered the treatment of the provision at the half year for gas holder demolition, as well as LIPA MSA transition and pension costs (described above). The Committee agreed that the classification of these items is appropriate.

Fair, balanced and understandable assessment: the Committee has considered the requirement of the Code to ensure that the Annual Report and Accounts, taken as a whole, is ‘fair, balanced and understandable’.

In reaching this conclusion the Committee reviewed, among other things, the impact of the introduction of the RIIO price control regime in the UK on the Group’s IFRS reported results, see pages 08 and 09 for more information.

Confidential reporting procedures and whistleblowing

The integrity of the financial statements is further supported by the confidential reporting and whistleblowing procedures we have in place. The Committee reviews these procedures once a year to make sure that complaints are treated confidentially and that a proportionate, independent investigation is carried out in all cases.

Internal (Corporate) Audit

The Corporate Audit function provides independent, objective assurance to the Audit, SEH and Executive Committees.

Audit work is delivered by a combination of internal resources – employees who typically have either a finance or operational business background – and external sources, where specific specialist skills are required.

The audit plan contains a mix of risk-based and cyclical reviews together with a small amount of work that is mandated, typically by US regulators. A number of focus areas are identified, such as financial, regulatory and asset management processes. Appropriate coverage is provided across each of these areas.

Inputs to the plan include risk registers, corporate priorities, external research of emerging risks and trends and discussions with senior management. A tool that captures all auditable areas, prior coverage and inherent process risk is also used to inform of audits that should be undertaken on a cyclical basis.

The plan is reviewed and approved by the Audit Committee in March each year, with focus given to not only the areas which are being covered but also those that are not, so we can make sure that the plan aligns with the Committee’s view of risk.

Corporate Audit provides a twice-yearly report to the Audit Committee. The report summarises common control themes arising and progress with implementing management action plans, and also presents information on specific audits as appropriate.

Where specific control issues are identified, senior leaders are invited to attend the Audit Committee to provide a commentary around the actions they are taking to improve the control environment within their area of responsibility.

Additional Information

External audit

The Committee is responsible for overseeing relations with the external auditors, including the approval of fees, and makes recommendations to the Board on their appointment and reappointment. Details of total remuneration to auditors for the year, including audit services, audit-related services and other non-audit services, can be found in note 3 (e) of the consolidated financial statements on page 98.

Auditor independence and objectivity

The independence of the external auditors is essential to the provision of an objective opinion on the true and fair view presented in the financial statements.

Auditor independence and objectivity is safeguarded by a number of control measures, including limiting the nature and value of non-audit services performed by the external auditors, ensuring that employees of the external auditors who have worked on the audit in the past two years are not appointed to senior financial positions within the Company, and the rotation of the lead engagement partner at least every five years. The current lead engagement partner has held the position for four years.

Audit quality

To maintain audit quality and provide comfort on the integrity of financial reporting, the Committee reviews and challenges the proposed external audit plan to make sure that PwC has identified all key risks and developed robust audit procedures.

The Committee also considers PwC’s response to accounting, financial control and audit issues as they arise, and meets with them at least annually without management present, providing the external auditors with the opportunity to raise any matters in confidence.

Auditor appointment

An annual review is conducted by the Committee of the level and constitution of the external audit and non-audit fees and the effectiveness, independence and objectivity of the external auditors.

The annual review includes consideration of:

— the external audit process globally;

— the auditors’ performance;

— the expertise of the firm and our relationship with them; and

— the results of questionnaires completed by National Grid

employees engaged with the audit and members of the

Audit Committee.

Following this year’s annual review, the Committee is satisfied with the effectiveness, independence and objectivity of the external auditors, and recommends to the Board their reappointment for a further year. A resolution to reappoint PwC and giving authority to the Directors to determine their remuneration will be submitted to shareholders at the 2014 AGM.

Audit tender

PwC have been the Company’s external auditors since the merger with Lattice Group plc in 2002, having been the incumbent external auditors of both the merging parties and the audit contract has not been put out to tender since then. Their performance has been reviewed annually by the Committee since that time.

During the year the Committee spent time discussing a potential tender for the external audit, following the new requirement on audit tendering and rotation of auditors.

The Committee has also discussed the implications of the proposals by both the UK Competition Commission (implementing its decision to mandate tendering every 10 years) and the EU (requiring audit firm rotation at least every 20 years), and will implement them when they become final. These proposals have effectively superceded the comply-or-explain provision that underpins the Code. The Financial Reporting Council has decided to defer consideration of whether to make any changes to these sections of the Code until its next review, currently scheduled for 2016.

The Committee considered the additional disruption that both an audit tender and any change in audit firm would involve in light of the ongoing US financial controls program, and the services we currently receive from other firms that may be considered in a tender process.

The Committee concluded that a tender is not in the Company’s interests at this time but agreed that this issue would be reviewed annually as part of the auditor appointment process. No representatives from PwC were present during the Committee’s discussion of the options for a tender of the external audit.

There are no contractual obligations restricting our choice of external auditors and we have not entered into any auditor liability agreement.

Non-audit services provided by the external auditors

Non-audit services provided by the external auditors require approval by the Committee. Approval is given on the basis the service will not compromise independence and is a natural extension of the audit or if there are overriding business or efficiency reasons making the external auditors most suited to provide the service. Certain services are prohibited from being performed by the external auditors, as required under the SOX Act.

Total non-audit services provided by PwC during the year ended 31 March 2014 were £1.7 million (2013: £2.3 million), which comprised 15% (2013: 23%) of total audit and audit-related fees.

Total audit and audit-related fees include the statutory fee and fees paid to PwC for other services that the external auditors are required to perform, for example regulatory audits and SOX Act attestation. Non-audit fees represent all other services provided by PwC not included in the above.

Significant non-audit services provided by PwC in the year included the review of US pensions and other post-retirement benefits census data (£0.5 million) and tax compliance services in territories other than the US (£0.5 million).

PwC were engaged to review census data used in US pensions and other post-retirement benefit calculations and advise on enhancements to procedures and controls surrounding census data completeness and accuracy.

The Committee considered PwC best placed to provide this service given their in-depth understanding of our processes and control environment. In order to maintain the external auditors’ independence and objectivity, the work was performed by a team independent of the audit team, management reviewed and considered PwC’s findings and PwC did not make any decisions on behalf of management. Additionally, PwC had no input in respect of the production of financial information subsequently used by the audit team.

The Committee also considered that tax compliance services were most efficiently provided by the external auditors, as much of the information used in preparing computations and returns is derived from audited financial information. In order to maintain the external auditors’ independence and objectivity, management reviewed and considered PwC’s findings and PwC did not make any decisions on behalf of management.

Audit information

Having made the requisite enquiries, so far as the Directors in office at the date of the approval of this report are aware, there is no relevant audit information of which the auditors are unaware and each Director has taken all reasonable steps to make themselves aware of any relevant audit information and to establish that the auditors are aware of that information.

Internal control, risk and compliance

We regularly consider the effectiveness of financial reporting, internal controls and compliance with applicable legal and internal requirements. We also review the procedures for the identification, assessment, mitigation and reporting of risks.

To continuously improve and remain at best practice levels, the risk management team reviews risk process standards, emerging trends and concepts being driven by the main consultancy firms and seeks to apply these as appropriate. The standards issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and the international risk standard ISO 31000 continue to inform the principles of our risk management process.

Specific improvements delivered during the year, and ongoing, were noted by the Committee at its meeting in September. These improvements include an enhanced approach for risk reporting to the Executive Committee, focusing on giving better visibility of mitigations and their impact on how risks are scored.

The scope of risk discussions has also been widened to incorporate specific consideration of our treatment of and preparedness for emerging risks (uncertainties on the horizon that are still developing and so may or may not evolve into threats or opportunities for us) and potential ‘black swan’ type events (catastrophic events of extremely high impact and extremely low likelihood).

The Board has participated in an interactive risk workshop to reinforce awareness of our key risks so its views can be captured and incorporated into our risk management activities. The output of this session formed part of the risk information reviewed at the March Audit Committee meeting.

Details of our internal control and risk management systems, including over the financial reporting process can be found on pages 22 and 25 and page 170. Our risk factors are described in full on pages 167 to 169.

Compliance management

The Global Ethics and Compliance team has continued to focus on promoting improved consistency of reporting on control frameworks across the compliance reporting process. The aim of this activity is to make sure any problem areas are transparent and that all parts of the business are applying a similar standard.

The Committee asked for a review of the key compliance areas that are subject to the reporting process. Currently, reporting focuses on legal compliance obligations only, and consideration is being given to whether all key areas are covered and what, if any, other areas should be included. The Committee also received the annual reports on the Company’s anti-bribery procedures and whistleblowing procedures and reviewed their adequacy. It noted that no material instances of non-compliance had been identified.

Going concern

Having made enquiries and reviewed management’s assessment of the going concern assumption, the Directors have a reasonable expectation that the Group has adequate resources to continue in operational existence for the next financial year and the foreseeable future. For this reason, the Directors are satisfied that, at the time of approving the financial statements, it is appropriate to continue to adopt the going concern basis in preparing the consolidated and individual financial statements of the Company.

Management’s assessment process

In accordance with the draft recommendations of the updated Financial Reporting Council guidance on going concern and liquidity risk, we have reviewed and amended our going concern assessment process.

Our process is an extension of our business planning process, and is further supplemented by our annual budget and other liquidity risk management controls. Our five year business plan and one year budget were reviewed and approved by the Board at its meetings in September 2013 and March 2014 respectively. The Finance Committee provides ongoing oversight of our liquidity policy, which requires us to maintain sufficient liquidity for a rolling 12 month period.

In light of our refreshed approach, we have reconsidered what the most appropriate ‘foreseeable future’ period is. Given our business model, current regulatory clarity and other factors affecting our operating environment, and the robustness of our business planning process and scenario analysis, we have concluded the foreseeable future period is the five years ending 31 March 2018, in line with our business plan. This period is considered to be the ‘foreseeable future’ as required for this going concern assessment only, and is in accordance with company law, accounting standards and the Listing Rules. We will reassess this period annually in light of developments in our operating environment, business model and strategic priorities.

Our business plan considers the significant solvency and liquidity risks involved in delivering our business model in light of our strategic priorities. The business plan models a number of upside and downside scenarios, derived from the risks and opportunities identified, and determines the impact these would have on our results and financial position over the five year period. In addition, we have reviewed and challenged a number of worst case scenarios and their possible remediation.

Our business model calls for significant capital investment to maintain and expand our network infrastructure. To deliver this, our business plan highlights that we will need to access capital markets to raise additional funds from time to time. We have a long and successful history in this regard; however, our business plan also models various KPIs used by lenders and credit rating agencies in assessing a company’s credit worthiness. These models indicate that we should continue to have access to capital markets at commercially acceptable interest rates throughout the five year period. To monitor and control risks around access to capital markets we have policies and procedures in place to help mitigate, as far as possible, any risk of a change in our credit ratings and other credit metrics.

More detail on our financial risks, including liquidity and solvency, is provided in note 30 to the consolidated financial statements. There have been no major changes to the Group’s significant liquidity and solvency risks in the year.

LOGO

Role

Sets policy and grants authority for financing decisions, credit exposure, hedging and foreign exchange transactions, guarantees and indemnities subject to the risk appetite approved by the Board. It also approves other treasury, tax, pension funding and insurance strategies and, if appropriate, recommends them to the Board.

Review of the year

The Finance Committee was established in 2002 to focus on the Company’s debt book to make sure these matters were given the necessary attention.

Following a number of new Non-executive Directors joining the Board in 2012/13, a presentation on the work and remit of the Committee was given to the Board in April 2013.

The presentation focused on the risks inherent in the areas the Finance Committee covers namely, treasury activities, insurance, pensions and tax. The presentation aimed to help all Directors understand the role and responsibilities of the Committee.

During the year, external advisors have given presentations to the Committee on matters such as capital markets, the results of a debt investor survey and the current state of banks. Additionally, information was circulated between meetings to make sure the Committee was kept fully briefed.

This year, we continued to focus on funding plans to take into account international debt market conditions. The Committee received regular reports on treasury, tax, insurance, pensions and commodity activities to keep us advised of progress and we approved recommendations where appropriate.

In July, after seven years as chair of this Committee, I will be stepping down from the Board. I have been working closely with Therese to ensure a smooth handover of responsibilities. I have no doubt the Committee will continue to perform effectively and evolve under Therese’s leadership.

Safety, Environment and Health Committee

LOGO

Role

In relation to safety, environment and health, the Committee reviews the strategies, policies, initiatives, risk exposure, targets and performance of the Company and, where appropriate, of its suppliers and contractors. It monitors the resources we use for compliance and driving improvement in these areas. The Committee also reviews investigations into major incidents and subsequent measures taken.

Review of the year

In terms of safety, our focus over the past year has again been on process safety. This includes the progress made, following the introduction of the new safety management system, in managing major hazard assets across our businesses, as well as the work required for the Company to become an industry leader in this area.

In particular, we have reviewed in depth the risks relating to our US LNG assets and the introduction of a new decision support tool for managing risks on gas transmission pipelines. We have also begun a review of the interfaces between our IT systems and safety processes.

Following a fatality and other incidents involving contractors in the US gas distribution business, we spent time with senior local management considering what measures needed to be put in place to promote a culture of safety among both employees and contractors and prevent a reoccurrence.

In relation to environmental matters, we have continued to monitor the Company’s strategy and approach to sustainability. In particular, we have looked at projects the Company is engaged in to reuse and recycle our resources such as overhead line conductors.

We have also reviewed the Company’s 2012 to 2016 Health and Wellbeing strategy. This includes a focus on mental wellbeing and how this affects not only employees’ absence, but also their levels of performance and engagement at work and in their home life. The Company is working to identify business areas most susceptible to workplace pressure that may impact employees’ mental wellbeing. We have started to provide training and information to reduce the stigma associated with mental illness as well as developing and promoting access to health and wellbeing support and treatment for affected employees.

It also identifies and proposes individuals to be Directors and executive management reporting directly to the Chief Executive, and establishes the criteria for any new position. Review of the year The Board is now in the final stages of its phased transition that commenced in 2011. Most recently we have welcomed Therese Esperdy and John Pettigrew to our Board and, following the AGM, Maria Richter will be stepping down from the Board. Nick Winser will also step down from the Board at this time, but will continue in his role as President of ENTSO-E and Chairman of NGET and NGG until July 2015 when he will be leaving the Company. Following the changes in Board membership, the composition of the committees was reviewed and updated to reflect the new balance of skills, knowledge and experience on the Board. Diversity of background, thinking styles and expertise have been important criteria in the transition of the Board. During the year the Committee reviewed our Board diversity policy. Progress against the policy was discussed and objectives to support the implementation of the policy were agreed, see page 56 for more details. The Committee agreed that the first objective should be to continue to meet, and aspire to exceed, the target of 25% of Board positions to be held by women by 2015. I look forward to reporting on our progress next year. Succession planning below Board level is also important. During the year the Committee with the Chief Executive reviewed the Executive Committee timeline and succession plans, rather than these being considered by the Board, to allow for a more open discussion. The presentation focused on succession cover to address the key risks and actions identified by an external assessment.

Appointment processes

Non-executive Director

The recruitment process undertaken for the appointment of Therese Esperdy was formal, rigorous and transparent. The Nominations Committee appointed Korn Ferry as the search consultancy, and the following process was undertaken:

— a role profile was prepared against which potential candidates were considered;

— Sir Peter Gershon interviewed an initial list of candidates, from which a shortlist of preferred candidates was selected;

— Maria Richter, Mark Williamson, Steve Holliday and Andrew Bonfield interviewed the shortlist of candidates and provided feedback to the Committee;

— the Committee considered these views in its deliberations before recommending a preferred candidate to the Board; and

— the Board approved the appointment as recommended.

In addition to providing external search consultancy services to the Company, a subsidiary of Korn Ferry provides external coaching to senior managers in the US.

Executive Director

John Pettigrew’s appointment to the Board as an Executive Director had been envisaged for some time. His executive career with the Company has been guided to make sure that he has experience of multiple parts of the business. His readiness and suitability for appointment to the Board was assessed by an external consultant.

As part of the appointment process, John Pettigrew was interviewed individually by Sir Peter Gershon, Mark Williamson, Jonathan Dawson and Ruth Kelly. The feedback from these meetings was discussed by the Committee before agreeing to recommend John’s appointment to the Board. The Board approved the recommendation to appoint John as an Executive Director. John’s role has not changed following his appointment to the Board.

Board diversity and the Davies Review

At National Grid, we believe that creating an inclusive and diverse culture supports the attraction and retention of talented people, improves effectiveness, delivers superior performance and enhances the success of the Company.

Our Board diversity policy promotes this and reaffirms our aspiration to meet and exceed the target of 25% of Board positions being held by women by 2015, as set out by Lord Davies.

We currently have 28% women on our Board, which will change to 25% on the departure of Maria Richter and Nick Winser, and 20% women on our Executive Committee.

The number of women in senior management positions and throughout the organisation is set out on page 41 along with examples of the initiatives to promote and support inclusion and diversity throughout our Company.

During the year the Committee reviewed the Board diversity policy and progress made. It also discussed and agreed the following objectives to support the implementation of the policy:

— the Board aspires to exceed the target of 25% of Board positions to be held by women by 2015;

— all Board appointments will be made on merit, in the context of the skills and experience that are needed for the Board to be effective;

— we will only engage executive search firms who have signed up to the voluntary code of conduct on gender diversity;

— where appropriate, we will assist with the development and support of initiatives that promote gender and other forms of diversity among our Board, executive and other senior management;

— where appropriate, we will continue to adopt best practice in response to the Davies Review;

— we will review our progress against the Board diversity policy annually;

— we will report on our progress against the policy and our objectives in the Annual Report and Accounts along with details of initiatives to promote gender and other forms of diversity among our Board, Executive Committee and other senior management; and

— we will continue to make key diversity data, both about the Board and our wider employee population, available in the Annual Report and Accounts.

Progress against the objectives and the policy will be reviewed annually and reported in the Annual Report and Accounts. The implementation of a successful diversity policy will need to be measured over a period of some years during which the size and shape of the Board may change to support the business.

Executive Committee

Led by the Chief Executive, the Executive Committee oversees the safety, operational and financial performance of the Company. It is responsible for making day-to-day management and operational decisions it considers necessary to safeguard the interests of the Company and to further the strategy, business objectives and targets established by the Board. The Committee plays an important role in the development of our people and in driving a high-performance culture.

It approves expenditure and other financial commitments within its authority levels and discusses, formulates and approves proposals to be considered by the Board.

There are currently 10 members on the Committee. They have a broad range of skills and expertise, which are updated through training and development. Some members also hold external non-executive directorships, giving them valuable board experience.

On a quarterly basis the Committee receives an inclusion and diversity scorecard which sets out statistics from the business at all levels in the UK and US. Progress against our aspirational inclusion and diversity targets is reviewed on an annual basis.

The Committee officially met 12 times this year, but the members interact much more regularly. Those members of the Committee who are not Directors all regularly attend Board and committee meetings for specific agenda items with Alison Kay, Group General Counsel & Company Secretary, being secretary to the Board and Nominations Committee. This means that knowledge is shared and every member is kept up to date with business activities and developments.

Remuneration

Report

LOGO

Annual statement from the Remuneration Committee chairman

I am delighted to present my first Directors’ Remuneration Report.

Following the introduction of a new UK regulatory framework in 2013 and the continued evolution of our US business, last summer the Committee initiated an extensive review of our executive remuneration strategy. Our objective was to assess whether the principles on which the current remuneration strategy is based continued to reflect our business drivers given recent changes. Our review concluded that a number of significant changes were appropriate. They are presented in this report for our shareholders’ consideration and, I hope, approval at our 2014 AGM.

The key factor in our discussions was to enhance the alignment of interest between executives and shareholders over the longer term. National Grid is a long-term business, where decisions taken today can have significant impact on performance and profitability over several years. Therefore the Committee believes that the bulk of incentives to executives should be paid in shares and that it is essential for high levels of personal shareholdings to become mandatory, rather than simply guidelines.

Having reached provisional conclusions I wrote to a number of our larger shareholders to seek their views. In the light of the constructive responses we received, the Committee amended its proposals and these amendments are incorporated into the recommendations in this report.

The key components of our recommendations are:

— A rebalancing of variable pay from the Annual Performance Plan (APP) to the Long Term Performance Plan (LTPP). It is proposed:

– to reduce the APP maximum from 150% of salary to 125% of salary for the CEO and the other Executive Directors; and

– to increase the LTPP maximum from 225% to 350% of salary for the CEO and from 200% to 300% of salary for the other Executive Directors.

— Increased alignment with shareholders by requiring Executive Directors to retain a significantly higher number of shares earned. It is proposed:

– for the CEO, the new requirement is a shareholding of 500% of pre-tax salary, equivalent to over nine years’ post-tax salary; and

– for the other Executive Directors, the new requirement is a shareholding of 400% of pre-tax salary.

— Stronger alignment with our business model and the long-term value drivers around a dividend-led total return. It is proposed to move to two key LTPP metrics – RoE (50% weighting) and value growth (50% weighting):

– RoE is aimed at focusing management on driving profits within the business; and

– value growth is viewed as a clearer indicator than EPS of the long-term growth of the business and the creation of shareholder value.

— Extended holding periods for incentive awards. It is proposed that any APP award is paid half in cash and half in shares. The shares would be paid immediately and be subject to a minimum holding period of two years. LTPP performance metrics would be measured over a three year period and awards would then be subject to a minimum two year holding period.

The Company’s commitment to increasing the annual dividend by at least RPI for the foreseeable future would be reflected in LTPP awards. The Committee will have the explicit power to reduce LTPP vesting should the Company fail to honour the dividend commitment, irrespective of the level of vesting resulting from the performance against the LTPP targets set by the Committee.

The consequence of all these changes is to reduce near-term cash incentives (APP) and tilt the balance to longer-term awards and longer-term shareholding exposure, with a greater proportion of Executive Directors’ remuneration earned in shares. As a result, we are striking an important balance between long-term reward and increased financial risk to executives through very high levels of mandatory shareholdings. In setting the quantum of future LTPP awards we have taken account of the reduced APP opportunity and longer holding periods that we are proposing. However, I want to assure shareholders that the Committee’s intention is that any increase in remuneration should arise from commensurate increases in long-term performance. We will therefore seek to ensure that targets set for the LTPP metrics contain appropriately demanding levels of performance to justify any increase in executive reward.

For the 2014 LTPP award we are proposing that maximum payout would require an average annual Group RoE of 12.5% and an average annual value growth of 12% over the three year performance period. The Committee considers these stretch targets, in the light of the business plan and recent performance, to be more challenging to management than those for LTPP set in the recent past. To achieve such a performance would require incremental Group pre-tax profits of over £250 million per annum, which in turn would imply achieved customer savings in the region of £100 – £200 million.

We can also confirm that, had the proposed APP and LTPP targets been applicable for 2013/14, no higher level of incentive remuneration would have resulted than was actually achieved under the current arrangements.

Additional Information


		In addition to the incentive plans review, the Committee reviewed future pension policy and the Executive Directors’ salaries. Last year there were no salary increases for Executive Directors. For the year ahead the Committee has awarded a 2.5% salary increase to Andrew Bonfield, Steve Holliday and Tom King, in line with the wider Group salary review budget. Nick Winser will not receive a salary increase, due to the fact that he is to stand down from the Board at the AGM in July 2014. John Pettigrew joined the Board on 1 April 2014 with a starting salary of £475,000 and will not receive a salary increase from 1 June 2014. His remuneration package is in line with the remuneration policy presented for approval in this report. In particular, his salary is below the Committee’s assessment of the market rate for equivalent roles. Subject to his performance, the Committee’s intention is to increase his salary towards market level by way of future phased increases in excess of those awarded to other Executive Directors. Our 2013/14 performance is set out on page 68. Overall, against the APP performance metrics of adjusted EPS, operating profit, US capital delivery, UK and US RoE and individual objectives, performance was ahead of target. As a result, we have made awards to the Executive Directors of between 83% and 129% of salary. Details of future targets and historical performance will be disclosed each year in respect of the LTPP, and details of historical performance will be disclosed each year in respect of the APP. The Committee believes that our proposals to restructure incentive pay are appropriate for the Company and on behalf of the Committee I commend them to shareholders. Jonathan Dawson Committee chairman						Directors’ remuneration policy The following tables provide details of the policy we intend to apply, subject to shareholder approval, for three years from the date of the 2014 AGM. Following approval it will be displayed on the Company’s website. There may be circumstances from time to time when the Committee will consider it appropriate to apply some judgement and exercise discretion in respect of the approved policy. This ability to apply discretion is highlighted where relevant in the policy, detailed on pages 60 to 66, and the use of discretion will always be in the spirit of the approved policy. The Committee will honour any commitments made to Directors before the policy outlined in this report comes into effect.
								Our peer group The Committee benchmarks its remuneration policy against appropriate peer groups annually to ensure we remain competitive in the relevant markets. The primary focus for reward benchmarking is the FTSE 11-40 for UK-based Executive Directors and general industry and energy services companies with similar levels of revenue for US-based Executive Directors. These peer groups are considered appropriate for a large, complex, international and predominantly regulated business.

Pension Purpose and link to strategy: to reward sustained contribution and assist attraction and retention.
Operation		Maximum levels	Performance metrics, weighting and time period applicable

Pension for a new Executive Director will reflect whether they are internally promoted or externally appointed.		UK DB: a maximum pension on retirement, at age 60, of two thirds final capped pensionable pay or up to one thirtieth accrual. On death in service, a lump sum of four times pensionable pay and a two thirds dependant’s pension is provided. UK DC: annual contributions of 30% of salary. Life assurance provision of four times pensionable salary and a spouse’s pension equal to one third of the Director’s salary are provided on death in service. US DB: an Executive Supplemental Retirement Plan provides for an unreduced pension benefit at age 62 (at age 55 in Tom King’s case). For retirements at age 62 with 35 years of service, the pension benefit would be approximately two thirds of pensionable pay. Upon death in service, the spouse would receive 50% of the pension benefit (100% if the participant died while an active employee after the age of 55). US DC: 9% of base salary plus APP with additional 401(k) plan match of up to 4%.	Not applicable.
If internally promoted:
—	retention of existing DB benefits without enhancement, except for capping of pensionable pay increases following promotion to Board; or
—	retention of existing UK DC benefits or equivalent cash in lieu; or
—	retention of existing US DC benefits plus 401(k) plan match, provided through 401(k) plan and non-qualified plans.
If externally appointed:
—	UK DC benefits or equivalent cash in lieu; or
—	US DC benefits plus 401(k) plan match.
Andrew Bonfield and John Pettigrew are treated in line with the above policy.
Steve Holliday and Nick Winser are provided with final salary pension benefits. For service prior to 1 April 2013, pensionable pay is normally the base salary in the 12 months prior to leaving the Company. For service from 1 April 2013 increases to pensionable pay are capped at the lower of 3% or the increase in inflation. Their pension scheme rules allow for indexed prior salaries to be used for all members. They both participate in the unfunded scheme in respect of benefits in excess of the Lifetime Allowance.
Tom King participates in a qualified pension plan and in an Executive Supplemental Retirement Plan. These plans are non-contributory, cash balance and final average pay plans. Tom’s benefits include compensation to buy out entitlements from his former employer that were lost on recruitment to National Grid. This includes a provision to allow an unreduced pension to be taken from age 55 if Tom is still in the employment of the Company at that time.
In line with market practice, pensionable pay for UK-based Executive Directors includes salary only and for US-based Executive Directors it includes salary and APP award.

Annual Purpose and link to strategy: to incentivise and reward the achievement of annual Performance Plan financial and strategic business targets and the delivery of annual individual objectives.
Operation	Maximum levels	Performance metrics, weighting and time period applicable

Performance metrics and targets are agreed at the start of each financial year. Performance metrics are aligned with strategic business priorities. Targets are set with reference to the budget. Awards are paid in June. For APP awards made in 2013/14, 50% of any award was deferred into shares in the Deferred Share Plan (DSP). The DSP has no performance conditions and vests after three years, subject to continued employment. These shares are subject to forfeiture for leavers in certain circumstances. For APP awards made in respect of years from 2014/15, it is proposed discontinuing the DSP. Instead 50% of awards will be paid in shares, which (after any sales to pay tax) must be retained until the shareholding requirement is met, and in any event for two years after receipt. Awards are subject to clawback and malus provisions.	From 2014/15, it is proposed that the maximum award will reduce from 150% of salary to 125% of salary.	A significant majority of the APP is based on performance against corporate financial measures, with the remainder based on performance against individual objectives. Individual objectives are role specific. The Committee may use its discretion to set measures that it considers appropriate in each financial year and reduce the amount payable, taking account of significant safety or customer service standard incidents, environmental and governance issues. For 2013/14, the APP was structured so that payout at threshold, target and stretch performance levels were 6.67%, 40% and 100% respectively. From 2014/15, it is proposed the payout levels will be amended so that payouts at threshold, target and stretch performance levels will be 0%, 50% and 100% respectively.




Long Term Purpose and link to strategy: to drive long-term performance, aligning Executive Performance Plan Director incentives to key strategic objectives and shareholder interests.
Operation	Maximum levels	Performance metrics, weighting and time period applicable

Awards of shares may be granted each year, with vesting subject to long-term performance conditions. The performance metrics have been chosen as the Committee believes they reflect the creation of long-term value within the business. Targets are set each year with reference to the business plan. Awards are subject to clawback and malus provisions. Notwithstanding the level of award achieved against the performance conditions, the Committee may use its discretion to reduce the amount vesting, and in particular will take account of compliance with the dividend policy.	From 2014, it is proposed that the maximum award for the CEO will increase from 225% of salary to 350% of salary and from 200% of salary to 300% of salary for the other Executive Directors.	For awards between 2011 and 2013 the performance measures and weightings were:
		—	adjusted EPS (50%) measured over three years;
		—	TSR relative to the FTSE 100 (25%) measured over three years; and
		—	UK or US RoE relative to allowed regulatory returns (25%) measured over four years.
		From 2014, it is proposed that the performance measures will be:
		—	value growth and Group RoE (for the CEO and Finance Director); and
		—	value growth, Group RoE and UK or US RoE (for the UK and US Executive Directors respectively).

Service contracts and policy on payment for loss of office In line with our policy, all Executive Directors have service contracts which are terminable by either party with 12 months’ notice. The contracts contain provisions for payment in lieu of notice, at the sole and absolute discretion of the Company. Such payments are limited to payment of salary only for the remainder of the notice period with the exception of Nick Winser. In Nick’s case the value of benefits would also be paid. In the UK such payments would be phased on a monthly basis, over a period no greater than 12 months, and the Executive Director would be expected to mitigate any losses where employment is taken up during the notice period. In the US, for tax purposes the policy is to make any payment in lieu of notice as soon as reasonably practicable, and in any event within two and a half months of the later of 31 December and 31 March immediately following the notice date. In the event of a UK Director being made redundant, statutory compensation would apply and the relevant pension plan rules may result in the early payment of an unreduced pension. On termination of employment, no APP award would generally be payable and any DSP awards would generally lapse. However, the Committee has the discretion to deem an individual to be a ‘good leaver’, in which case an APP award would be payable on the termination date, based on performance during the financial year up to termination, and DSP awards would vest on the termination date. Examples of circumstances in which a Director would be treated as a ‘good leaver’ include redundancy, retirement, illness, injury, disability and death. Any APP award would be prorated and would be subject to performance achieved against the objectives for that year. On termination of employment, outstanding awards under the share plans will be treated in accordance with the relevant plan rules approved by shareholders. Share awards would normally lapse. ‘Good leaver’ provisions apply at the Committee’s discretion and in specified circumstances, including redundancy, retirement, illness, injury, disability and death, where awards will be released to the departing Executive Director or, in the case of death, to their estate. Long-term share plan awards held by ‘good leavers’ may vest subject to performance measured at the normal vesting date and are prorated. Such awards would vest at the same time as for other participants. The Chairman’s appointment is subject to six months’ notice by either party; for the other Non-executive Directors, notice is one month. No compensation is payable to Non-executive Directors if required to stand down. Copies of Directors’ service contracts and letters of appointment are available to view at the Company’s registered office.	Dates of Directors’ service contracts/letters of appointment

		4.		APP calculations are based on 125% of salary for the period 1 April 2014 to 31 March 2015.
		5.		LTPP calculations are based on awards with a face value of 350% of 1 June 2014 salary for Steve Holliday and 300% of 1 June 2014 salary for all other Executive Directors.
		6.		LTPP and APP payout is 50% for on target performance and the maximum is 100% for achieving stretch performance.
		7.		Tom King’s remuneration opportunity has been converted at $1.62:£1.
		Statement of consideration of shareholder views The Committee considers all feedback received from shareholders throughout the year. While the Committee understands that not all shareholders’ views will be the same, we consult with our larger shareholders on a regular basis to understand their expectations with regard to executive remuneration issues and any changes in shareholder views in this regard. In 2013/14 larger shareholders were consulted on the proposed changes to remuneration policy. Shareholders were supportive of the direction of change proposed, particularly increasing holding periods for awards and retention thresholds. Several responses suggested a number of small changes and where possible the Committee has reflected these changes in the proposals.

2. Benefits in kind include private medical insurance, life assurance, either a fully expensed car or a cash alternative to a car and the use of a driver when required. For Andrew Bonfield, a cash allowance in lieu of additional pension contributions is included within pension rather than benefits in kind.

3. The APP value is the full award before the 50% mandatory deferral into the DSP.

4. During the year, the 2010 PSP award vested and entered a retention period, to be released in June 2014. The above value is based on the share price (744 pence) on the vesting date (1 July 2013). In the prior year the 2009 PSP award vested and entered a retention period, to be released in June 2013. The above valuation is based on the share price (681 pence) on the vesting date (2 July 2012).

5. The pension values for Steve Holliday and Nick Winser represent the additional benefit earned in the year (excluding inflation as measured by the consumer price index (CPI)), multiplied by a factor of 20, less the contributions they made.

6. The pension value for Tom King represents the additional benefit earned in the year multiplied by a factor of 20, plus the Company’s contributions (£7,854) to the 401(k) plan.

7. Andrew Bonfield was a member of the DC pension plan during the year. The pension value represents 30% of salary via a combination of cash allowance in lieu of pension £185,120 (2012/13: £184,385) and Company pension contributions £28,480 (2012/13: £28,367). He opted out of the pension plan from 1 April 2014 and now receives the full cash allowance in lieu of pension of 30% of salary.

8. Pension figures in last year’s report were based on the draft disclosure regulations. The 2012/13 figures in the above table are therefore amended from last year’s report to reflect the final regulations.

2013/14 PSP performance (audited information) The PSP value included in the 2013/14 single total figure relates to vesting of the conditional PSP award granted in 2010. Vesting was determined as at 30 June 2013 and was dependent on performance over the three years ending 31 March 2013 for the EPS measure and over the three years ending 30 June 2013 for the TSR measure. Transfer remains conditional upon continued service until 30 June 2014. The performance achieved against the performance targets was:
Performance measure		Threshold – 25% vesting							Maximum – 100% vesting							Actual			Proportion of maximum achieved

TSR ranking		Ranked at median of the comparator group (FTSE 100)							7.5 percentage points or more above median							5.7 percentage points above median							83.3%

Adjusted EPS		EPS growth exceeds RPI increase by 3 percentage points							EPS growth exceeds RPI increase by 8 percentage points or more							Exceeded RPI by 6.5 percentage points							77.9%

Total																							80.6%

1.	The total proportion of maximum achieved is the weighted average of the proportion of maximum achieved for each performance measure. Each of the two measures had a 50% weighting.

Total pension entitlements (audited information) The table below provides details of the Executive Directors’ pension benefits:
		Total contributions to DC-type pension plan £’000	Cash in lieu of contributions to DC-type pension plan £’000	Accrued pension at 31 March 2014 £’000 pa	Increase in accrued pension over year, net of inflation £’000 pa	Transfer value of accrued benefits as at 31 March 2014 £’000		Transfer value of increase in accrued pension over year, net of inflation £’000		Normal retirement date

Andrew Bonfield		28	185	–	–	–		–		17/08/2027

1.	The UK-based Executive Directors participate in FPS, a salary sacrifice arrangement for pension contributions. Contributions paid via salary sacrifice have been deducted from the figures in the table above.
2.	For Steve Holliday, in addition to the pension above, there is an accrued lump sum entitlement of £125,000 as at 31 March 2014. There was no increase to the accumulated lump sum including and excluding inflation in the year to 31 March 2014. The transfer value information above includes the value of the lump sum. Steve paid contributions of £44,000 via FPS.
3.	For Nick Winser, in addition to the pension above, there is an accrued lump sum entitlement of £313,000 as at 31 March 2014. The increase to the accumulated lump sum including inflation was £7,000 and excluding inflation was £nil in the year to 31 March 2014. The transfer value information above includes the value of the lump sum. Nick paid contributions of £33,000 via FPS.
4.	For Tom King, the exchange rate as at 31 March 2014 was $1.67:£1 and as at 31 March 2013 was $1.52:£1. In addition to the transfer value quoted above, through participation in a 401(k) plan in the US, the Company made contributions worth £7,854 to a DC arrangement.
5.	The increase in accrued pension figures for Steve Holliday and Nick Winser are net of inflation based on RPI for September 2013. The figures in the single figure table on page 67 are based on inflation using CPI for September 2012. If the same inflation measure was used for this table the relevant figures would be an increase in pension of £23,100 for Steve and £12,250 for Nick. Multiplying these figures by a factor of 20 and deducting member contributions correlates to the values in the single figure table. Tom King’s pension figures do not allow for inflation as US pensions in payment or deferment do not increase in line with inflation. For Tom, multiplying the increase in accrued pension over the year, shown above (£55,150), by a factor of 20 and adding Company contributions to a DC-type pension plan, shown above, correlates to the value in the single figure table.
6.	There are no additional benefits in the event of early retirement.

Shareholder dilution

Where shares may be issued or treasury shares reissued to satisfy incentives, the aggregate dilution resulting from executive share-based incentives will not exceed 5% in any 10 year period. Dilution resulting from all incentives, including all-employee incentives, will not exceed 10% in any 10 year period. The Committee reviews dilution against these limits regularly and under these limits the Company, as at 31 March 2014, had headroom of 4.01% and 7.99% respectively.

Statement of Directors’ shareholdings and share interests (audited information)

The Executive Directors are required to build up and hold a shareholding from vested share plan awards. Deferred share awards are not taken into account for these purposes until the end of the deferral period. Shares are valued for these purposes at the 31 March 2014 price, which was 822 pence per share ($68.74 per ADS).

The following table shows how each Executive Director complies with the shareholding requirement and also the number of shares owned by the Non-executive Directors, including connected persons. For Ken Harvey and George Rose, the shareholding is as at the date they stepped down from the Board. For all others it is 31 March 2014.

The salary used to calculate the value of shareholding is the salary earned in the year.

Andrew Bonfield has not met the shareholding requirement as none of the share awards in the plans in which he has participated have been released yet.

On 31 March 2014 Andrew Bonfield held 3,421 options granted under the Sharesave plan. These options were granted at a value of 445 pence per share, and they can be exercised at 445 pence per share between April 2016 and September 2016.

On 12 June 2013 Steve Holliday exercised two Share Match awards, totalling 37,475 shares. This comprised (i) an award of 16,092 options, expiring in June 2013, exercised for 100 pence in total, and (ii) an award of 21,383 options, expiring in May 2014, exercised for nil value. These shares are included in the table above (‘Number of shares owned outright’). In addition, on 7 April 2014, he exercised a Sharesave option over 3,921 shares at the option price of 427.05 pence per share before expiration in September 2014.

Relative importance of spend on pay

This chart shows the relative importance of spend on pay compared with other costs and disbursements (dividends, tax, net interest and capital expenditure). Given the capital-intensive nature of our business and the scale of our operations, these costs were chosen as the most relevant for comparison purposes. All amounts exclude exceptional items, remeasurements and stranded cost recoveries.

Percentage change in CEO’s remuneration The table below shows how the percentage change in the CEO’s salary, benefits and APP between 2013/14 and 2012/13 compares with the percentage change in the average of each of those components of remuneration for non-union employees in the UK. The Committee views this group as the most appropriate comparator group, as the CEO is UK-based and this group excludes employees represented by trade unions, whose pay and benefits are negotiated with each individual union.

1. Committee chair fees are in addition to the committee membership fee. Advisors to the Remuneration Committee The Committee received advice until 31 July 2013 from independent remuneration consultants Towers Watson. From 1 August 2013 the Committee received advice from independent remuneration consultants New Bridge Street (NBS), a trading name of Aon Hewitt Ltd (part of Aon plc). NBS were selected as advisors by the Committee following a competitive tendering process. Work undertaken by these advisors included updating the Committee on trends in compensation and governance matters and advising the Committee in connection with benchmarking of the total reward packages for the Executive Directors and other senior employees. NBS and Towers Watson are members of the Remuneration Consultants Group and have signed up to that group’s Code of Conduct. Towers Watson also provides general remuneration, pension and benefits advice and services to the Company. The Committee is satisfied that any potential conflicts were appropriately managed. NBS does not provide any other advice or services to the Company. In the year to 31 March 2014 the Committee paid a total of £262,000 to NBS and Towers Watson, with fees being charged on a time incurred basis. The Committee also received specialist advice from the following organisations:
Ÿ Alithos Limited: provision of TSR calculations for the PSP and LTPP (£25,000 paid in 2013/14);
• Linklaters LLP: advice relating to share schemes and to Directors’ service contracts as well as providing other legal advice to the Company (£26,000 paid in 2013/14); and
Ÿ KPMG LLP: advice relating to pension matters (£72,000 paid in 2013/14).
The Committee reviews the objectivity and independence of the advice it receives from its advisors each year. It is satisfied that they all provided credible and professional advice. The Committee considers the views of the Chairman on the performance and remuneration of the CEO; and of the CEO on the performance and remuneration of the other members of the Executive Committee. The Committee is also supported by the Group General Counsel & Company Secretary who acts as Secretary to the Committee, the Group HR Director, the Global Head of Reward and the Global Head of Pensions. No other advisors have provided significant services to the Committee in the year. Voting on 2012/13 Remuneration Report at 2013 AGM

financial statements


We have continued to develop our presentational format to provide shareholders and users of these financial statements with additional information and guidance, and to make them easier to understand. Throughout these financial statements we have included additional information boxes, providing helpful commentary on what the disclosures mean and why they are important to the understanding of our financial performance and position. Some of these boxes highlight ‘Our strategy in action’, drawing out the key elements of our business model (set out in the Strategic Report on pages 14 and 21), and showing how the disclosures reflect this strategy.
		Audit opinions We have two audit opinions on our financial statements, reflecting our dual listing on the London Stock Exchange and the New York Stock Exchange. Due to the different reporting requirements for each listing, our auditors are required to confirm compliance with each set of standards in a prescribed format. The IFRS audit opinion has changed this year, reflecting the change to auditing standards, which requires the auditors to provide more detail as to how they have planned and completed their audit, as well as their views on significant matters they have noted and that were discussed by the Audit Committee. There are also additional specific disclosure requirements due to our US listing which are included in the notes. Notes Notes to the financial statements provide additional information required by statute, accounting standards or other regulations to assist in a more detailed understanding of the primary financial statements. In many notes we have included an accounting policy that describes how the transactions or balance in that note have been measured, recognised and disclosed. The basis of preparation section provides details of accounting policies that apply to transactions and balances in general.

		Unaudited commentary We have presented with the financial statements certain analysis previously included in the financial review section of the Strategic Report of our Annual Report. This approach provides a more understandable narrative, a logical flow of information and reduces duplication. We have created a combined financial review, including a commentary on items within the primary statements, on pages 84 to 91. Unless otherwise indicated, all analysis provided in the financial statements is on a statutory IFRS basis. All information in ruled boxes styled in the same manner as this one does not form part of the audited financial statements. This has been further highlighted by including the word ‘unaudited’ at the start of each box header. Unaudited commentary boxes appear on pages 85 to 87, 89, 91, 96, 106, 108 and 121.

to the Board of Directors and Shareholders of National Grid plc

Audit opinion for Form 20-F

In our opinion, the accompanying consolidated statements of financial position and the related consolidated income statements, consolidated statements of comprehensive income, consolidated cash flow statements and consolidated statements of changes in equity, present fairly, in all material respects, the financial position of National Grid plc and its subsidiaries at 31 March 2014 and 31 March 2013, and the results of their operations and their cash flows for each of the three years in the period ended 31 March 2014 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board and in conformity with International Financial Reporting Standards as adopted by the European Union.

Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of 31 March 2014, based on criteria established in Internal Control – Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the Additional Information section appearing on page 170 of the 2014 Annual Report and Accounts. As discussed in note 1, the Group changed the manner in which it accounts for employee benefits.

Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorisations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorised acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Basis of

preparation


	Accounting policies describe our approach to recognising and measuring transactions and balances in the year. Accounting policies applicable across the financial statements are shown below. Accounting policies that are specific to a component of the financial statements have been incorporated into the relevant note. This section also shows areas of judgement and key sources of estimation uncertainty in these financial statements. In addition, we summarise new EU endorsed accounting standards, amendments and interpretations and whether these are effective in 2014 or later years, explaining how significant changes are expected to affect our reported results.	A. Basis of consolidation The consolidated financial statements incorporate the financial statements of the Company and its subsidiaries, together with a share of the results, assets and liabilities of jointly controlled entities (joint ventures) and associates using the equity method of accounting, where the investment is carried at cost plus post-acquisition changes in the share of net assets of the joint venture or associate, less any provision for impairment. A subsidiary is defined as an entity controlled by the Company. Control is achieved where the Company has the power to affect the returns of an entity to which it is exposed or to which it has rights. Losses in excess of the consolidated interest in joint ventures and associates are not recognised, except where the Company or its subsidiaries have made a commitment to make good those losses. Where necessary, adjustments are made to bring the accounting policies used in the individual financial statements of the Company, subsidiaries, joint ventures and associates into line with those used by the Company in its consolidated financial statements under IFRS. Intercompany transactions are eliminated. The results of subsidiaries, joint ventures and associates acquired or disposed of during the year are included in the consolidated income statement from the effective date of acquisition or up to the effective date of disposal, as appropriate. Acquisitions are accounted for using the acquisition method, where the purchase price is allocated to the identifiable assets acquired and liabilities assumed on a fair value basis and the remainder recognised as goodwill. B. Foreign currencies Transactions in currencies other than the functional currency of the Company or subsidiary concerned are recorded at the rates of exchange prevailing on the dates of the transactions. At each reporting date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at closing exchange rates. Non-monetary assets are not retranslated unless they are carried at fair value. Gains and losses arising on the retranslation of monetary assets and liabilities are included in the income statement, except where the adoption of hedge accounting requires inclusion in other comprehensive income – note 15. On consolidation, the assets and liabilities of operations that have a functional currency different from the Company’s functional currency of pounds sterling, principally our US operations that have a functional currency of dollars, are translated at exchange rates prevailing at the reporting date. Income and expense items are translated at the weighted average exchange rates for the period where these do not differ materially from rates at the date of the transaction. Exchange differences arising are classified as equity and transferred to the consolidated translation reserve.
National Grid’s principal activities involve the transmission and distribution of electricity and gas in Great Britain and northeastern US. The Company is a public limited liability company incorporated and domiciled in England, with its registered office at 1-3 Strand, London WC2N 5EH. The Company has its primary listing on the London Stock Exchange and is also quoted on the New York Stock Exchange. These consolidated financial statements were approved for issue by the Board of Directors on 18 May 2014. These consolidated financial statements have been prepared in accordance with International Accounting Standards (IAS) and International Financial Reporting Standards (IFRS) and related interpretations as issued by the International Accounting Standards Board (IASB) and IFRS as adopted by the EU. They are prepared on the basis of all IFRS accounting standards and interpretations that are mandatory for periods ending 31 March 2014 and in accordance with the Companies Act 2006 applicable to companies reporting under IFRS and Article 4 of the EU IAS Regulation. The 2013 and 2012 comparative financial information has also been prepared on this basis. The consolidated financial statements have been prepared on an historical cost basis, except for the recording of pension assets and liabilities, the revaluation of derivative financial instruments and certain commodity contracts and investments classified as available-for-sale. The consolidated financial statements have been prepared on a going concern basis following the assessment made by the Directors as set out on page 52. These consolidated financial statements are presented in pounds sterling, which is also the functional currency of the Company. The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities and the reported amounts of revenue and expenses during the reporting period (see accounting policy C).

C. Areas of judgement and key sources of estimation uncertainty

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Information about such judgements and estimations is contained in the notes to the financial statements, and the key areas are summarised below.

Areas of judgement that have the most significant effect on the amounts recognised in the financial statements are as follows:

— the categorisation of certain items as exceptional items, remeasurements and stranded cost recoveries and the definition of adjusted earnings – notes 4 and 7; and

— energy purchase contracts classification as being for normal purchase, sale or usage – note 27.

IFRS provides certain options available within accounting standards. Choices we have made, and continue to make, include the following:

· Presentational formats: we use the nature of expense method for our income statement and aggregate our statement of financial position to net assets and total equity. In the income statement, we present subtotals of total operating profit, profit before tax and profit from continuing operations, together with additional subtotals excluding exceptional items, remeasurements and stranded cost recoveries. Exceptional items, remeasurements and stranded cost recoveries are presented separately on the face of the income statement.

· Customer contributions: contributions received prior to 1 July 2009 towards capital expenditure are recorded as deferred income and amortised in line with the depreciation on the associated asset.

· Financial instruments: we normally opt to apply hedge accounting in most circumstances where this is permitted. For net investment hedges, we have chosen to use the spot rate method, rather than the alternative forward rate method.

Key sources of estimation uncertainty that have significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are as follows:

— impairment of goodwill – note 9;

— review of residual lives, carrying values and impairment charges for other intangible assets and property, plant and equipment – notes 10 and 11;

— estimation of liabilities for pensions and other post-retirement benefits – notes 22 and 29;

— valuation of financial instruments and derivatives – notes 15 and 30;

— revenue recognition and assessment of unbilled revenue – note 2;

— recoverability of deferred tax assets – note 6; and

— environmental and decommissioning provisions – note 23.

In order to illustrate the impact that changes in assumptions could have on our results and financial position, we have included sensitivity analysis in note 33.

New IFRS accounting standards and interpretations adopted in 2013/14

During the year ended 31 March 2014, with the exception of IAS 19 (revised), and in respect of disclosures required by IFRS 13 ‘Fair value measurements’, the Company has not adopted any new IFRS, IAS or amendments issued by the IASB, or interpretations issued by the IFRS Interpretations Committee (IFRIC), which have had a material impact on the Company’s consolidated financial statements. The impact of IAS 19 (revised) is set out in note 1. The additional disclosures required by IFRS 13 are included in note 30.

Other standards, interpretations and amendments issued by the IASB and IFRIC that have not had a material impact on the Company’s consolidated results or assets and liabilities are:

— IFRS 10 ‘Consolidated financial statements’;

— IFRS 11 ‘Joint arrangements’;

— IFRS 12 ‘Disclosure of interests in other entities’;

— amendments to IAS 27 ‘Separate financial statements’ and IAS 28 ‘Investments in associates and joint ventures’ as a result of the adoption of the above standards;

— amendments to IAS 1 ‘Presentation of financial statements’; and

— amendments to IFRS 7 ‘Financial instruments: Disclosures’.

New IFRS accounting standards and interpretations not yet adopted

The Company enters into a significant number of transactions that fall within the scope of IFRS 9 ‘Financial instruments’. The IASB is completing IFRS 9 in phases and the Company is evaluating the impact of the standard as it develops. It is currently expected that the standard will be required to be adopted by the Company on 1 April 2018. We are currently assessing the likely impact of this standard on the Company’s consolidated financial statements.

Other standards and interpretations or amendments thereto which have been issued, but are not yet effective, are not expected to have a material impact on the Company’s consolidated financial statements.

Unaudited commentary on the consolidated income statement
The consolidated income statement shows all revenue earned and costs incurred in the year, with the difference being the overall profit for the year.		Adjusted earnings and EPS The following chart shows the five year trend in adjusted profit attributable to equity shareholders of the parent (adjusted earnings) and adjusted EPS.
Revenue Revenue for the year ended 31 March 2014 increased by £450m to £14,809m. This increase was driven by higher revenues in our UK Electricity Transmission and UK Gas Distribution businesses, principally as a result of the new RIIO regulatory arrangements. Revenue in our US Regulated businesses was also higher, reflecting higher pass-through costs such as gas and electricity commodity costs, partially offset by the end of the Niagara Mohawk deferral revenue recoveries at 31 March 2013 and the impact of the weaker dollar. Operating costs Operating costs for the year ended 31 March 2014 of £11,074m were £464m higher than the prior year. This increase in costs was predominantly due to increases in pass-through costs in our UK and US Regulated businesses, together with higher depreciation and amortisation as a result of continued investment and increases in our controllable costs. Exceptional items, remeasurements and stranded cost recoveries included in operating costs for the year ended 31 March 2014 were £39m lower than the prior year. Net exceptional gains included in 2013/14 of £55m primarily consisted of a net gain on the LIPA MSA transition in the US of £254m, a gain of £16m following the sale to a third party of a settlement award, restructuring costs of £136m and UK gas holder demolition costs of £79m. The 2013/14 results also included a gain of £16m on remeasurements of commodity contracts. There were no major storms affecting our operations in the year ended 31 March 2014. In 2012/13, two major storms in the US, Superstorm Sandy and Storm Nemo, increased operating costs by £136m. Net finance costs For the year ended 31 March 2014, net finance costs before exceptional items and remeasurements were £16m lower than 2012/13 at £1,108m, mainly due to the impact of the weaker dollar (£17m). Finance costs for the year ended 31 March 2014 also included a gain of £93m on financial remeasurements relating to net gains and losses on derivative financial instruments. Taxation The tax charge on profits before exceptional items, remeasurements and stranded cost recoveries was £38m lower than 2012/13. This was mainly due to a 1% decrease in the UK statutory corporation tax rate in the year and a change in the UK/US profit mix where higher UK profits were taxed at the lower UK tax rate. Our tax charge was also affected by changes in tax provisions in respect of prior years.		Adjusted earnings and adjusted EPS¹ 1. All comparatives restated for IAS 19 (revised). See note 1 on page 92. Adjusted earnings and adjusted EPS are attributable to equity shareholders of the parent. The above earnings performance translated into adjusted EPS growth in 2013/14 of 2.6p (5%). In accordance with IAS 33, all EPS and adjusted EPS amounts for comparative periods have been restated for shares issued via scrip dividends and the bonus element of the 2010 rights issue. Exchange rates Our financial results are reported in sterling. Transactions for our US operations are denominated in dollars, so the related amounts that are reported in sterling depend on the dollar to sterling exchange rate. The weighted average dollar rate weakened to $1.62:£1 in 2013/14 from $1.57:£1 in 2012/13. Consequently, if 2012/13 results had been translated at 2013/14 exchange rates, revenue, adjusted operating profit and operating profit reported in sterling would have been £242m, £34m and £39m lower respectively. The statement of financial position has been translated at an exchange rate of $1.67:£1 at 31 March 2014 ($1.52: £1 at 31 March 2013).
Exceptional tax for 2013/14 included an exceptional deferred tax credit of £398m arising from a reduction in the UK corporation tax rate from 23% to 21% applicable from 1 April 2014 and a further reduction to 20% from 1 April 2015.

Unaudited commentary on consolidated statement of comprehensive income
The consolidated statement of comprehensive income records certain items as prescribed by the accounting rules. For us, the majority of the income or expense included here relates to movements in actuarial assumptions on pension schemes and the associated tax impact. These items are not part of profit for the year, yet are important to allow the reader to gain a more comprehensive picture of our performance as a whole.				Exchange adjustments Adjustments are made when we translate the results and net assets of our companies operating outside the UK, as well as debt we have issued in foreign currencies. The net movement for the year resulted in a loss of £158m (2012/13: £117m gain). Net gains/(losses) in respect of cash flow hedges The value of derivatives held to hedge cash flows is impacted by changes in expected interest rates and exchange rates. The net gain for the year was £63m (2012/13: £31m loss). This unaudited commentary does not form part of the financial statements.
Remeasurements of net retirement benefit obligations We had a net gain after tax of £313m (2012/13: net cost of £535m) on our pension and other post-employment benefit schemes which is due to changes in key assumptions made in the valuation calculation and differences to actual outcomes during the year.

Unaudited commentary on consolidated statement of changes in equity
The consolidated statement of changes in equity shows the additions (where it came from) and reductions (where it went) to equity. For us, the main items included here are the profit earned and dividends paid in the year.				Dividends We paid a total of £1,503m dividends to shareholders in the year (2012/13: £1,433m) of which £444m (2012/13: £623m) was settled via scrip issues. The Directors are proposing a final dividend of 27.54p, bringing the total dividend for the year to 42.03p, a 2.9% increase on 2012/13. The Directors intend to continue the dividend policy announced last year of increasing the annual dividend by at least the rate of RPI inflation for the foreseeable future.

Unaudited commentary on consolidated statement of financial position
The consolidated statement of financial position sets out all the Group’s assets and liabilities at the year end. As a capital-intensive business, we have significant amounts of physical assets and corresponding borrowings.	of £42m, more than offset by foreign exchange movements of £112m and utilisation of £288m in relation to all classes of provisions. Other non-current liabilities decreased by £43m principally due to foreign exchange movements of £47m. Net debt Net debt is the aggregate of cash and cash equivalents, current financial and other investments, borrowings, and derivative financial assets and liabilities. See further analysis with the consolidated cash flow statement on page 90. Net pension and other post-retirement obligations A summary of the total UK and US assets and liabilities and the overall net IAS 19 (revised) accounting deficit is shown below:
Goodwill and other intangible assets Goodwill and intangibles decreased by £354m to £5,263m as at 31 March 2014. This decrease primarily relates to foreign exchange movements of £472m and software amortisation of £127m, partially offset by software additions of £179m.
Property, plant and equipment Property, plant and equipment increased by £587m to £37,179m as at 31 March 2014. This was principally due to capital expenditure of £3,262m on the renewal and extension of our regulated networks, offset by foreign exchange movements of £1,244m, and £1,299m of depreciation in the year. Investments and other non-current assets Investments in joint ventures and associates, financial and other investments and other non-current assets have decreased by £31m to £722m. This is principally due to changes in the fair value of our US commodity contract assets and available-for-sale investments. Inventories and current intangible assets, and trade and other receivables Inventories and current intangible assets, and trade and other receivables have decreased by £78m to £3,123m at 31 March 2014. This decrease is principally due to foreign exchange movements of £195m, partially offset by an increase in trade and other receivables of £120m mostly due to colder weather in the US in February and March 2014 compared with 2013 resulting in increased billings for commodity costs and customer usage. Trade and other payables Trade and other payables have decreased by £20m to £3,031m due to favourable foreign exchange movements of £150m, partially offset by higher payables in the UK due in part to changes in payment terms with new Gas Distribution strategic partners and increased activity on the Western Link project. Current tax liabilities Current tax liabilities have decreased by £63m to £168m as at 31 March 2014. This is primarily due to higher tax payments made in 2013/14 although these were partially offset by a larger current year tax charge. Deferred tax liabilities Deferred tax liabilities have increased by £5m to £4,082m as at 31 March 2014. This was primarily due to the impact of the £172m deferred tax charge on actuarial gains (a £179m tax credit in 2012/13) being offset by the impact of the reduction in the UK statutory tax rate for future periods, foreign exchange movements and the reduction in prior year charges. Provisions and other non-current liabilities Provisions (both current and non-current) and other non-current liabilities decreased by £158m to £3,486m as at 31 March 2014. Total provisions decreased by £115m in the year. The underlying movements include additions of £230m primarily relating to a provision for the demolition of certain gas holders in the UK of £79m, restructuring provisions of £86m and other provisions	Net plan liability	UK £m	US £m	Total £m

	The principal movements in net obligations during the year include a curtailment gain of £214m following the LIPA MSA transition, net actuarial gains of £485m and employer contributions of £596m. Net actuarial gains include actuarial gains on plan liabilities of £542m arising as a consequence of an increase in the UK real discount rate and the nominal discount rate in the US. This is partially offset by actuarial losses of £283m arising from increases in life expectancy in the US. Actuarial (losses)/gains on plan assets reflects the asset allocations in the different plans. In both the UK and US, returns on equities were above the assumed rate; however, UK government securities had negative returns and corporate bonds were close to nil. Further information on our pension and other post-retirement obligations can be found in notes 22 and 29 to the consolidated financial statements. Details of the restatements made for IAS 19 (revised) can be found in note 1. Off balance sheet items There were no significant off balance sheet items other than the contractual obligations shown in note 30 (b) to the consolidated financial statements, and the commitments and contingencies discussed in note 27. Through the ordinary course of our operations, we are party to various litigation, claims and investigations. We do not expect the ultimate resolution of any of these proceedings to have a material adverse effect on our results of operations, cash flows or financial position. This unaudited commentary does not form part of the financial statements.

Additional Information

Unaudited commentary on consolidated cash flow statement

The consolidated cash flow statement shows how the cash balance has moved during the year. Cash inflows and outflows are presented to allow users to understand how they relate to the day-to-day operations of the business (operating activities); the money that has been spent or earned on assets in the year, including acquisitions of physical assets or other businesses (investing activities); and the cash raised from debt or share issues and other loan borrowings or repayments (financing activities).

receivables increased due to colder weather in the US in February and March 2014, cash outflows relating to exceptional items were £38m higher due to reorganisation in the UK and LIPA MSA transition costs in the US.

Net capital expenditure

Net capital expenditure in the year of £3,119m was £238m lower than the prior year. This was a result of lower spend in our UK regulated businesses, the impact of the weaker dollar, and reduced capital spend on the US enterprise resource system in 2013/14.

Net interest paid

Net interest paid in 2013/14 was £866m, £103m higher than 2012/13, due to higher average net debt levels.

Tax paid

Tax paid in the year to 31 March 2014 was £400m, £113m higher than prior year. This reflected higher tax payments in the UK on higher taxable profits.

Net acquisitions and disposals

There were no material acquisitions or disposals in the year. The year ended 31 March 2013 included proceeds received on the disposal of our gas and electricity businesses in New Hampshire in the US.

Dividends paid

Dividends paid in the year ended 31 March 2014 amounted to £1,059m. This was £249m higher than 2012/13, reflecting the 4% increase in the final dividend for the year ended 31 March 2013 paid in August 2013, together with a lower average scrip dividend take-up in the year. Given the relatively high scrip uptake for the dividend paid in August 2013, no scrip option was offered for the interim dividend paid in January 2014.

Other cash movements

Other cash flows principally arise from dividends from joint ventures and movements in treasury shares.

Non-cash movements

The non-cash movements are predominantly due to the change in foreign exchange arising on net debt held in currencies other than sterling. In the year ended 31 March 2014, the dollar weakened from $1.52 at 31 March 2013 to $1.67 at 31 March 2014. This has caused a reduction in the sterling value of net debt.

Other non-cash movements are from changes in fair values of financial assets and liabilities and interest accretions and accruals.

LOGO

Cash flows from our operations are largely stable when viewed over the longer term. Our electricity and gas transmission and distribution operations in the UK and US are subject to multi-year rate agreements with regulators. In the UK, we have largely stable intra-year cash flows. However, in the US our short-term cash flows are dependent on the price of gas and electricity and the timing of customer payments. The regulatory mechanisms for recovering costs from customers can result in significant cash flow swings from year to year. Changes in volumes in the US, for example as a consequence of abnormally mild or extreme weather can affect cash flows, particularly in the winter months.

For the year ended 31 March 2014, cash flow from operations increased by £382m to £4,419m.

Adjusted operating profit before depreciation, amortisation and impairment was £81m higher year on year. Changes in working capital improved by £351m over the prior year, principally in the US due to the collection of receivables from LIPA relating to Superstorm Sandy. Partially offsetting this improvement,

1. Adoption of IAS 19 (revised) ‘Employee benefits’
This note sets out the impact that the required adoption of IAS 19 (revised) ‘Employee benefits’ has had on our previously reported results. It provides details of the originally reported and the restated figures.
During the year, the Group adopted IAS 19 (revised) ‘Employee benefits’. The adoption constitutes a change in accounting policy and therefore the comparative information has been restated. The standard requires past service costs to be recognised immediately in profit or loss and all actuarial gains and losses are recognised in other comprehensive income as they occur. The standard also replaces the interest cost on the DB obligation and the expected return on plan assets with a net interest cost based on the net DB asset or liability and the discount rate, measured at the beginning of the year. The impact on the Group for the years ended 31 March 2013 and 31 March 2012 is set out in the table below:

The effect of the change in accounting policy on the statement of cash flows was immaterial, with no impact on the cash position at any of the reporting dates. We have revised our pension and other post-retirement benefit obligations disclosures in notes 22 and 29 to provide greater clarity by separately presenting our UK and US pension plans due to their different risk profiles.

		2. Segmental analysis
		This note sets out the financial performance for the year split into the different parts of the business (operating segments). We monitor and manage the performance of these operating segments on a day-to-day basis. Our strategy in action We own a portfolio of businesses that range from cash generative developed assets with minimal investment requirements (such as National Grid Metering, included within Other activities) to businesses with high levels of investment and growth (such as UK Electricity Transmission). We generate 95% of our revenue from our regulated businesses in the UK and US. We work with our regulators to obtain agreements that balance the risks we face with the opportunity to deliver reasonable returns for our investors. When investing in non-regulated businesses we aim to leverage our core capabilities to deliver higher returns for investors. Our regulated businesses earn revenue for the transmission, distribution and generation services they have provided during the year. In any one year, the revenue recognised may differ from that allowed under our regulatory agreements and any such timing differences are adjusted through future prices. Our non-regulated businesses earn revenue in line with their contractual terms.
		Revenue primarily represents the sales value derived from the generation, transmission and distribution of energy, together with the sales value derived from the provision of other services to customers and, previously, recovery of US stranded costs during the year. It excludes value added (sales) tax and intra-group sales. Revenue includes an assessment of unbilled energy and transportation services supplied to customers between the date of the last meter reading and the year end. This is estimated based on historical consumption and weather patterns. Where revenue exceeds the maximum amount permitted by regulatory agreement and adjustments will be made to future prices to reflect this over-recovery, no liability is recognised, as such an adjustment relates to the provision of future services. Similarly no asset is recognised where a regulatory agreement permits adjustments to be made to future prices in respect of an under-recovery. US stranded costs were various generation-related costs incurred prior to the divestiture of generation assets beginning in the late 1990s and costs of legacy contracts that are being recovered from customers. The recovery of stranded costs and other amounts allowed to be collected from customers under regulatory arrangements was recognised in the period in which these amounts were recoverable from customers. The recovery of stranded costs was substantially completed at 31 March 2012. We present revenue and the results of the business analysed by operating segment, based on the information the Board of Directors uses internally for the purposes of evaluating the performance of operating segments and determining resource allocation between operating segments. The Board is National Grid’s chief operating decision-making body (as defined by IFRS 8 ‘Operating Segments’) and assesses the performance of operations principally on the basis of operating profit before exceptional items, remeasurements and stranded cost recoveries (see note 4). Following the commencement of new RIIO regulatory arrangements in the UK, we have changed the way in which we report our operational and financial performance. We have reviewed our segmental disclosure for the year ended 31 March 2014 with the separation of our UK Transmission segment into two new segments: UK Electricity Transmission and UK Gas Transmission. We have also moved the Great Britain-France electricity interconnector from UK Electricity Transmission to Other activities. The information given in this note for the years ended 31 March 2013 and 2012 has been restated to provide a like-for-like comparison.

2. Segmental analysis continued The following table describes the main activities for each operating segment:

UK Electricity Transmission		High voltage electricity transmission networks in Great Britain.

UK Gas Transmission		The gas transmission network in Great Britain and UK LNG storage activities.

UK Gas Distribution		Four of the eight regional networks of Great Britain’s gas distribution system.

US Regulated		Gas distribution networks, electricity distribution networks and high voltage electricity transmission networks in New York and New England (including EnergyNorth and Granite State up to the date they were sold on 3 July 2012) and electricity generation facilities in New York and Massachusetts.

Other activities primarily relate to non-regulated businesses and other commercial operations not included within the above segments, including: the Great Britain-France electricity interconnector; UK-based gas metering activities; UK property management; a UK LNG import terminal; US LNG operations; US unregulated transmission pipelines; together with corporate activities. Sales between operating segments are priced considering the regulatory and legal requirements to which the businesses are subject. The analysis of revenue by geographical area is on the basis of destination. There are no material sales between the UK and US geographical areas. (a) Revenue

		Unaudited commentary on the results of our principal operations by segment
		We have summarised the results of our principal operating segments here by segment to provide direct reference to the results as disclosed in note 2. This analysis has been performed based on operating profit before exceptional items, remeasurements and stranded cost recoveries as set out in note 2 (b).				US Regulated Revenue in our US Regulated businesses was £122m higher at £8,040m, and adjusted operating profit fell by £129m to £1,125m. The weaker dollar reduced operating profit in the year by £38m. Excluding the impact of foreign exchange, net regulated income fell by £52m, principally due to the end of deferral income recoveries for Niagara Mohawk at 31 March 2013. Timing differences added another £29m profit compared with prior year. Regulated controllable costs increased by £89m at constant currency as a result of inflation and wage increases, higher insurance costs post Superstorm Sandy, and cost true-ups identified during the implementation of new financial systems. Other operating costs (excluding major storms) increased by £61m at constant currency due to the higher cost of non-major storm remediation, higher property taxes and depreciation of the new US enterprise resource system. There were no major storms affecting our operations in the year ended 31 March 2014. In 2012/13, two major storms in the US, Superstorm Sandy and Storm Nemo, reduced operating profit within US Regulated by £82m at constant currency. Our capital investment programme continues in the US, with a further £1,219m invested in 2013/14, including gas leak reduction programmes and gas growth and connection spend. Other activities Revenue in Other activities increased by £58m to £736m in the year ended 31 March 2014. Adjusted operating profit was £120m higher at £131m. There was no repeat of the major storm cost of £51m incurred in our insurance captive in the prior year due to Superstorm Sandy. Operating profit in the French interconnector was £62m higher as a result of strong auction revenues this year. In our other non-regulated businesses, adjusted operating profit was £7m higher due to improved results in our UK metering business and insurance captive, partially offset by higher costs associated with the stabilisation of the new US enterprise resource system. Capital expenditure in our Other activities was £37m lower at £180m, principally reflecting reduced capital spend on the new US enterprise resource system. This unaudited commentary does not form part of the financial statements.
		UK Electricity Transmission For the year ended 31 March 2014, revenue in the UK Electricity Transmission segment increased by £277m, and adjusted operating profit increased by £38m. Net regulated income after pass-through costs was £170m higher, reflecting increases in allowed revenues under the new RIIO regulatory framework. This was partially offset by under-recoveries of revenue in the year of £60m compared with over-recoveries of £29m in the prior year. Regulated controllable costs were £27m higher due to inflation, legal fees and one-off credits in the prior year. Depreciation and amortisation was £20m higher reflecting the continued capital investment programme (investment in the year was £1,381m). Other costs were £4m lower than prior year. UK Gas Transmission Revenue in the UK Gas Transmission segment decreased by £177m in 2013/14 to £941m and adjusted operating profit fell by £114m to £417m. Net regulated income after pass-through costs was £80m lower, with lower permit income than prior year under the new RIIO arrangements. In addition, under-recoveries in the year of £21m compared with over-recoveries last year of £17m, gave rise to an adverse timing movement of £38m. Depreciation and amortisation was £10m higher due to investment, with £181m invested in the year. Partially offsetting these, other operating costs were £14m lower. UK Gas Distribution UK Gas Distribution revenue increased by £184m in the year to £1,898m, and adjusted operating profit increased to £904m from £794m in 2012/13. Net regulated income after pass-through costs was £96m higher, reflecting increases in allowed revenues under the new RIIO regulatory framework. Timing differences added another £39m, with £29m over-recoveries in 2013/14, compared with a £10m under-recovery in the prior year. Partially offsetting these, regulated controllable costs were £14m higher primarily due to inflation. Depreciation and amortisation was £10m higher reflecting the continued capital investment programme (investment in the year was £480m). Other costs were £1m higher than prior year.

		4. Exceptional items, remeasurements and stranded cost recoveries
		To monitor our financial performance, we use a profit measure that excludes certain income and expenses. We call that measure ‘business performance’. We exclude items from business performance because we think these items are individually important to understanding our financial performance. If included, these items could distort understanding of our performance for the year and the comparability between periods. This note analyses these items, which are included in our results for the year but are excluded from business performance.
		Our financial performance is analysed into two components: business performance, which excludes exceptional items, remeasurements and stranded cost recoveries; and exceptional items, remeasurements and stranded cost recoveries. Business performance is used by management to monitor financial performance as it is considered that it improves the comparability of our reported financial performance from year to year. Business performance subtotals are presented on the face of the income statement or in the notes to the financial statements. Items of income or expense that are considered by management for designation as exceptional items include such items as significant restructurings, write-downs or impairments of non-current assets, significant changes in environmental or decommissioning provisions, integration of acquired businesses, gains or losses on disposals of businesses or investments and debt redemption costs as a consequence of transactions such as significant disposals or issues of equity. Costs arising from restructuring programmes include redundancy costs. Redundancy costs are charged to the income statement in the year in which a commitment is made to incur the costs and the main features of the restructuring plan have been announced to affected employees. Remeasurements comprise gains or losses recorded in the income statement arising from changes in the fair value of commodity contracts and of derivative financial instruments to the extent that hedge accounting is not achieved or is not effective. These fair values increase or decrease because of changes in commodity and financial indices and prices over which we have no control. Stranded cost recoveries represent the recovery, through charges to electricity customers in upstate New York and New England, of historical generation-related costs, related to generation assets that are no longer owned by National Grid. Such costs have been recovered from customers as permitted by regulatory agreements, with substantially all having been recovered by 31 March 2012.

1. Restructuring costs for the period of £136m related to the continued restructuring of our UK operations in preparedness to deliver RIIO, other transformation-related initiatives in the UK and US and an associated software impairment for licences that will no longer be used. Restructuring costs for 2013 included: costs related to the restructuring of our UK operations of £66m in preparedness for delivering RIIO; costs for transformation-related initiatives in the UK and US of £31m; and a credit of £10m for the release of restructuring provisions in the UK recognised in prior years. For the year ended 31 March 2012, restructuring costs included: costs for the restructuring of our US operations of £58m, which included severance costs and pension and other post-retirement curtailment gains and losses; costs for transformation-related initiatives of £54m; and a credit of £11m for the release of restructuring provisions in the UK recognised in prior years. 2. A provision of £79m (2013: £nil) has been made for the demolition of certain non-operational gas holders in the UK. 3. A net gain of £254m (2013: £nil) has been recognised in the year ended 31 March 2014. This includes a pension curtailment and settlement gain of £214m for employees who transferred to a new employer following the cessation of the Management Services Agreement (MSA) with LIPA on 31 December 2013. There was also a gain of £142m following the extinguishment of debt obligations of £98m and a £56m cash payment to be received, in compensation for the Company forgiving a historic pension receivable and carrying charges. These gains were offset by transition costs and other provisions incurred to effect the transition. For the year ended 31 March 2012, an impairment charge of £64m was recognised, representing intangibles (originally recognised on the acquisition of KeySpan) related to our LIPA MSA contract. This amount was previously disclosed as impairment charges and related costs. 4. During the year ended 31 March 2014, £16m (2013: £nil) was received following the sale to a third party of a settlement award which arose as a result of a legal ruling in 2008. For the year ended 31 March 2012, an amortisation charge of £5m in relation to acquisition-related intangibles was offset by a release of £6m of unutilised provisions in our UK metering business. 5. For the year ended 31 March 2013, we recognised a gain of £3m on the disposal of two subsidiaries in New Hampshire. During the year ended 31 March 2012, we sold two other subsidiaries resulting in a gain on disposal of £72m. We also recognised gains of £25m in relation to disposals of businesses in prior years, representing the release of various unutilised provisions. 6. Remeasurements – commodity contracts represent mark-to-market movements on certain physical and financial commodity contract obligations in the US. These contracts primarily relate to the forward purchase of energy for supply to customers, or to the economic hedging thereof, that are required to be measured at fair value and that do not qualify for hedge accounting. Under the existing rate plans in the US, commodity costs are recoverable from customers although the timing of recovery may differ from the pattern of costs incurred. 7. For the year ended 31 March 2013, stranded cost recoveries of £14m substantially represented the release of an unutilised provision recognised in a prior period. For the year ended 31 March 2012, stranded cost recoveries on a pre-tax basis consisted of revenue of £279m offset by operating costs of £19m. This represented the recovery of some of our historical investments in generating plants that were divested as part of the restructuring and wholesale power deregulation process in New England and New York during the 1990s. 8. Remeasurements – net gains/(losses) on derivative financial instruments comprise gains/(losses) arising on derivative financial instruments reported in the income statement. These exclude gains and losses for which hedge accounting has been effective, which have been recognised directly in other comprehensive income or which are offset by adjustments to the carrying value of debt. The tax charge in the year includes a credit of £nil (2013: £1m; 2012: £1m) in respect of prior years. 9. The exceptional tax credit arises from reductions in the UK corporation tax rate, from 23% to 21% applicable from 1 April 2014, and a further reduction from 21% to 20% applicable from 1 April 2015. The rate reductions were enacted in the Finance Act 2013. Other UK tax legislation also reduced the UK corporation tax rate in the prior periods (2013: from 24% to 23%; 2012: from 26% to 24%). These reductions have resulted in a decrease in deferred tax liabilities. 10. The exceptional tax charge arises from a net increase in US state income tax rates. Effective from 1 April 2014, the state income tax rate for Massachusetts regulated utilities increased from 6.5% to 8% and, effective from 1 April 2016, the state income tax rate for New York will decrease from 7.1% to 6.5%.

		Tax is payable in the territories where we operate, mainly the UK and US. This note gives further details of the tax charge and tax liabilities, including current and deferred tax. The current tax charge is the tax payable on this year’s taxable profits. Deferred tax is an accounting adjustment to provide for tax that is expected to arise in the future due to differences in accounting and tax bases.
The tax charge for the period is recognised in the income statement, the statement of comprehensive income or directly in equity, according to the accounting treatment of the related transaction. The tax charge comprises both current and deferred tax. Current tax assets and liabilities are measured at the amounts expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amounts are those that have been enacted or substantively enacted by the reporting date. The calculation of the Group’s total tax charge involves a degree of estimation and judgement, and management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation and establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities. Deferred tax is provided for using the balance sheet liability method and is recognised on temporary differences between the carrying amount of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit. Deferred tax liabilities are generally recognised on all taxable temporary differences and deferred tax assets are recognised to the extent that it is probable that taxable profits will be available against which deductible temporary differences can be utilised. However, deferred tax assets and liabilities are not recognised if the temporary differences arise from the initial recognition of goodwill or from the initial recognition of other assets and liabilities in a transaction (other than a business combination) that affects neither the accounting nor taxable profit or loss. Deferred tax liabilities are recognised on taxable temporary differences arising on investments in subsidiaries and jointly controlled entities except where the Company is able to control the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised, based on the tax rates and tax laws that have been enacted or substantively enacted by the reporting date. The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the deferred tax asset to be recovered. Unrecognised deferred tax assets are reassessed at each reporting date and are recognised to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered. Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Company and its subsidiaries intend to settle their current tax assets and liabilities on a net basis.

1. See note 1 on page 92. Factors that may affect future tax charges The Finance Act 2013 (the Act) was substantively enacted on 2 July 2013. The Act further reduced the main rate of UK corporation tax to 21% with effect from 1 April 2014 and 20% from 1 April 2015. The reduction in the UK corporation tax rate to 20% from 1 April 2015 has been enacted and deferred tax balances have been calculated at this rate. Effective from 1 April 2014, the state income tax rate for Massachusetts regulated utilities increased from 6.5% to 8% and, effective from 1 April 2016, the state income tax rate for New York will decrease from 7.1% to 6.5%. Neither of these rate changes is expected to have a material impact on the Group’s effective tax rate.

Deferred tax assets and liabilities are only offset where there is a legally enforceable right of offset and there is an intention to settle the balances net. The deferred tax balances (after offset) for statement of financial position purposes consist solely of deferred tax liabilities of £4,082m (2013: £4,077m).
At the reporting date there were no material current deferred tax assets or liabilities (2013: £nil).
Deferred tax assets in respect of capital losses, trading losses and non-trade deficits have not been recognised as their future recovery is uncertain or not currently anticipated. The deferred tax assets not recognised are as follows:
									2014 £m			2013 £m

Capital losses										274		323
Non-trade deficits										1		1
Trading losses										5		11

The capital losses and non-trade deficits that arise in the UK are available to carry forward indefinitely. However, the capital losses can only be offset against specific types of future capital gains and non-trade deficits against specific future non-trade profits. The trading losses arising in the US have up to a 20 year carry forward time limit.
The aggregate amount of temporary differences associated with the unremitted earnings of overseas subsidiaries and joint ventures for which deferred tax liabilities have not been recognised at the reporting date is approximately £2,118m (2013: £1,817m). No liability is recognised in respect of the differences because the Company and its subsidiaries are in a position to control the timing of the reversal of the temporary differences and it is probable that such differences will not reverse in the foreseeable future. In addition, as a result of a change in UK tax legislation, which largely exempts overseas dividends received on or after 1 July 2009 from UK tax, the temporary differences are unlikely to lead to additional tax.

Unaudited commentary on taxation Tax strategy National Grid manages its tax affairs in a proactive and responsible way in order to comply with all relevant legislation and minimise reputational risk. We have a good working relationship with all relevant tax authorities and actively engage with them in order to ensure that they are fully aware of our view of the tax implications of our business initiatives. Management responsibility and oversight for our tax strategy, which is approved by the Finance Committee, rests with the Finance Director and the Global Tax and Treasury Director who monitor our tax activities and report to the Finance Committee. Total UK tax contribution National Grid has taken the decision to provide additional information in respect of its total UK tax contribution and first disclosed this in last year’s annual report. This year we have again disclosed information in respect of our total UK tax contribution for consistency and to aid transparency in an area in which there has been increasing public interest. As was the case in the prior year, the total amount of taxes we pay and collect in the UK year on year is significantly more than just the corporation tax which we pay on our UK profits. Within the total, we again include significant other taxes paid such as business rates and taxes on employment together with employee taxes and other indirect taxes. For 2013/14 our total tax contribution to the UK Exchequer was £1.4bn (2012/13: £1.2bn). Taxes borne in 2014 were £733m, an 8% increase on taxes borne in 2013 of £678m and primarily due to higher corporation tax payments in the current year. Our 2012/13 total tax contribution of £1.2bn resulted in National Grid being the 17th highest contributor of UK taxes based on the results of the Hundred Group’s 2013 Total Tax Contribution Survey, a position commensurate with the size of our business and capitalisation relative to other contributors to the survey. In 2012 we were in 16th position. In 2013 we ranked 9th in respect of taxes borne. Of course, National Grid’s contribution to the UK economy is broader than just the taxes it pays over to and collects on behalf of HMRC. The Hundred Group’s 2013 Total Tax Contribution Survey ranks National Grid in 4th place in respect of UK capital expenditure on fixed assets and we also rank highly in respect of investment in research and development. National Grid’s economic contribution also supports a significant number of UK jobs in our supply chain. The most significant amounts making up the 2013/14 total tax contribution were as follows: UK total tax contribution 2013/14	Tax transparency The UK tax charge for the year disclosed in the accounts in accordance with accounting standards and the UK corporation tax paid during the year will differ. For transparency we have included a reconciliation below of the tax charge per the income statement to the UK corporation tax paid in 2013/14. The tax charge for the Group as reported in the income statement is £284m (2012/13: £557m). The UK tax charge is £51m (2012/13: £307m) and UK corporation tax paid was £329m (2012/13: £243m), with the principal differences between these two measures as follows:
		Year ended 31 March
	Reconciliation of UK total tax charge to UK corporation tax paid		2014 £m		2013 (restated)¹ £m

	Total UK tax charge (current tax £346m (2013: £289m) and deferred tax £295m credit (2013: £18m charge))		51		307

	UK corporation tax paid		329		243

	1. All comparatives restated for IAS 19 (revised). See note 1 on page 92. Tax losses We have total unrecognised deferred tax assets in respect of losses of £280m (2012/13: £335m) of which £274m (2012/13: £319m) are capital losses in the UK as set out on page 105. These losses arose as a result of the disposal of certain businesses or assets and may be available to offset against future capital gains in the UK. Development of future tax policy We believe that the continued development of a coherent and transparent tax policy in the UK is critical to help drive growth in the economy. We continue to contribute to research into the structure of business taxation and its economic impact by contributing to the funding of the Oxford University Centre for Business Taxation at the Saïd Business School. We are a member of a number of industry groups which participate in the development of future tax policy, including the Hundred Group, which represents the views of finance directors of FTSE 100 companies and several other large UK companies. Our Finance Director is Chairman of its Tax Committee. This helps to ensure that we are engaged at the earliest opportunity on taxation issues which affect our business. For example, in the current year we have engaged with and responded to a number of HMRC consultations, the subject matter of which has a direct impact on taxes borne or collected by our business, and reviewed numerous others with a potential impact.

7. Earnings per share (EPS)
EPS is the amount of post-tax profit attributable to each ordinary share. Basic EPS is calculated on profit for the year attributable to equity shareholders divided by the weighted average number of shares in issue during the year. Diluted EPS shows what the impact would be if all outstanding share options were exercised and treated as ordinary shares at year end.
Adjusted EPS, excluding exceptional items, remeasurements and stranded cost recoveries, are provided to reflect the business performance subtotals used by the Company. For further details of exceptional items, remeasurements and stranded cost recoveries, see note 4.

8. Dividends

Dividends represents the return of profits to shareholders. Dividends are paid as an amount per ordinary share held. We retain part of the profits generated in the year to meet future growth plans and pay out the remainder in accordance with our dividend policy.

Interim dividends are recognised when they become payable to the Company’s shareholders. Final dividends are recognised when they are approved by shareholders.

The following table shows the actual dividends paid to equity shareholders:

The Directors are proposing a final dividend for the year ended 31 March 2014 of 27.54p per share that will absorb approximately £1,028m of shareholders’ equity (assuming all amounts are settled in cash). It will be paid on 20 August 2014 to shareholders who are on the register of members at 6 June 2014 and a scrip dividend will be offered as an alternative, subject to shareholders’ approval at the AGM.

Unaudited commentary on dividends

Following the announcement of our new dividend policy in March 2013, we remain confident that our business is able to support a dividend rising at least in line with inflation for the foreseeable future, while continuing to invest as required in our regulated asset bases. The dividend cover chart opposite supports our decision.

With the exception of the 2013/14 interim dividend paid in January this year, a scrip option has been offered for all interim and final dividends in the last three years. The scrip take-up was as follows: 2012/13 final: 46%; 2012/13 interim: 35%; and 2011/12 final: 48%.

	9. Goodwill
	Goodwill represents the excess of what we paid to acquire businesses over the fair value of their net assets at the acquisition date. We assess whether goodwill is recoverable each year by performing an impairment review.
	Goodwill is recognised as an asset and is not amortised, but is tested for impairment annually, or more frequently if events or changes in circumstances indicate a potential impairment. Any impairment is recognised immediately in the income statement and is not subsequently reversed.
	Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and translated at the closing exchange rate.
	Impairment
	Goodwill is allocated to cash-generating units and this allocation is made to those cash-generating units that are expected to benefit from the business combination in which the goodwill arose.
	Impairments of goodwill are calculated as the difference between the carrying value of the goodwill and the estimated recoverable amount of the cash-generating unit to which that goodwill has been allocated. Recoverable amount is defined as the higher of fair value less costs to sell and estimated value-in-use at the date the impairment review is undertaken.
	Value-in-use represents the present value of expected future cash flows, discounted using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.
	Impairments are recognised in the income statement and are disclosed separately.

	The amounts disclosed above as at 31 March 2014 include balances relating to the following cash-generating units: New York £2,640m (2013: £2,898m); Massachusetts £987m (2013: £1,082m); Rhode Island £367m (2013: £403m); and Federal £600m (2013: £645m).
	Additions during the year relate to a further investment in Clean Line Energy Partners LLC, a developer of long-distance, HVDC transmission projects in the US to move renewable energy to market. Under IFRS 10, this investment is now accounted for as a subsidiary rather than an equity investment. National Grid has a 37% interest, but has the option to increase this holding.
	Goodwill is reviewed annually for impairment and the recoverability of goodwill at 31 March 2014 has been assessed by comparing the carrying amount of our operations described above (our cash-generating units) with the expected recoverable amount on a value-in-use basis. In each assessment, the value-in-use has been calculated based on five year plan projections that incorporate our best estimates of future cash flows, customer rates, costs, future prices and growth. Such projections reflect our current regulatory rate plans taking into account regulatory arrangements to allow for future rate plan filings and recovery of investment. Our plans have proved to be reliable guides in the past and the Directors believe the estimates are appropriate.
	The future growth rate used to extrapolate projections beyond five years has been maintained at 2.25% (2013: 2.25%). The growth rate has been determined having regard to data on projected growth in US real gross domestic product (GDP). Based on our business’ place in the underlying US economy, it is appropriate for the terminal growth rate to be based upon the overall growth in real GDP and, given the nature of our operations, to extend over a long period of time. Cash flow projections have been discounted to reflect the time value of money, using an effective pre-tax discount rate of 9% (2013: 9%). The discount rate represents the estimated weighted average cost of capital of these operations.
	While it is possible that a key assumption in the calculation could change, the Directors believe that no reasonably foreseeable change would result in an impairment of goodwill, in view of the long-term nature of the key assumptions and the margin by which the estimated fair value exceeds the carrying amount.

10. Other intangible assets
Other intangible assets includes software and acquisition-related assets (such as brand names and customer relationships), which are written down (amortised) over the period we expect to receive a benefit from the asset.
Identifiable intangible assets are recorded at cost less accumulated amortisation and any provision for impairment. Other intangible assets are tested for impairment only if there is an indication that the carrying value of the assets may have been impaired. Impairments of assets are calculated as the difference between the carrying value of the asset and the recoverable amount, if lower. Where such an asset does not generate cash flows that are independent from other assets, the recoverable amount of the cash-generating unit to which that asset belongs is estimated. Impairments are recognised in the income statement and are disclosed separately. Any assets which suffered impairment in a previous period are reviewed for possible reversal of the impairment at each reporting date.
Internally generated intangible assets, such as software, are recognised only if: an asset is created that can be identified; it is probable that the asset created will generate future economic benefits; and the development cost of the asset can be measured reliably. Where no internally generated intangible asset can be recognised, development expenditure is recorded as an expense in the period in which it is incurred.
On a business combination, as well as recording separable intangible assets possessed by the acquired entity at their fair value, identifiable intangible assets that arise from contractual or other legal rights are also included in the statement of financial position at their fair value. Acquisition-related intangible assets principally comprise customer relationships.
Other intangible assets are amortised on a straight-line basis over their estimated useful economic lives. Amortisation periods for categories of intangible assets are:

11. Property, plant and equipment
The following note shows the physical assets controlled by us. The cost of these assets primarily represents the amount initially paid for them. A depreciation expense is charged to the income statement to reflect annual wear and tear and the reduced value of the asset over time. Depreciation is calculated by estimating the number of years we expect the asset to be used (useful economic life) and charging the cost of the asset to the income statement equally over this period. Our strategy in action We operate an energy networks business and therefore have a significant physical asset base. We continue to invest in our networks to maintain reliability, create new customer connections and ensure our networks are flexible and resilient. Our business plan envisages these additional investments will be funded through a mixture of cash generated from operations and the issue of new debt.
Property, plant and equipment is recorded at cost, less accumulated depreciation and any impairment losses. Cost includes the purchase price of the asset, any payroll and finance costs incurred which are directly attributable to the construction of property, plant and equipment as well as the cost of any associated asset retirement obligations. Property, plant and equipment includes assets in which the Company’s interest comprises legally protected statutory or contractual rights of use. Additions represent the purchase or construction of new assets, including capital expenditure for safety and environmental assets, and extensions to, enhancements to, or replacement of, existing assets. Contributions received prior to 1 July 2009 towards the cost of property, plant and equipment are included in trade and other payables as deferred income and credited on a straight-line basis to the income statement over the estimated useful economic lives of the assets to which they relate. Contributions received post 1 July 2009 are recognised in revenue immediately, except where the contributions are consideration for a future service, in which case they are recognised initially as deferred income, and revenue is subsequently recognised over the period in which the service is provided. No depreciation is provided on freehold land or assets in the course of construction. Other items of property, plant and equipment are depreciated, on a straight-line basis, at rates estimated to write off their book values over their estimated useful economic lives. In assessing estimated useful economic lives, consideration is given to any contractual arrangements and operational requirements relating to particular assets. The assessments of estimated useful economic lives and residual values of assets are performed annually. Unless otherwise determined by operational requirements, the depreciation periods for the principal categories of property, plant and equipment are, in general, as shown in the table below:
	Years

Freehold and leasehold buildings		up to 65
Plant and machinery
Electricity transmission plant		15 to 60
Electricity distribution plant		15 to 60
Electricity generation plant		20 to 40
Interconnector plant		15 to 60
Gas plant – mains, services and regulating equipment		30 to 100
Gas plant – storage		15 to 21
Gas plant – meters		10 to 33
Motor vehicles and office equipment		up to 10

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are, depending on their magnitude, recognised as an exceptional item within operating profit in the income statement. Items within property, plant and equipment are tested for impairment only if there is some indication that the carrying value of the assets may have been impaired. Impairments of assets are calculated as the difference between the carrying value of the asset and the recoverable amount, if lower. Where such an asset does not generate cash flows that are independent from other assets, the recoverable amount of the cash-generating unit to which that asset belongs is estimated. Material impairments are recognised in the income statement and are disclosed separately. Any assets which suffered impairment in a previous period are reviewed for possible reversal of the impairment at each reporting date.

13. Financial and other investments

Financial and other investments includes two main categories. Assets classified as available-for-sale typically represent investments in short-term money funds and quoted investments in equities or bonds of other companies. The second category is loans and receivables which includes bank deposits with a maturity of greater than three months, and cash balances that cannot be readily used in operations, principally collateral pledged for certain borrowings and restricted cash balances relating to our UK pension schemes.

Financial assets, liabilities and equity instruments are classified according to the substance of the contractual arrangements entered into, and recognised on trade date. Available-for-sale financial assets are non-derivatives that are either designated in this category or not classified in any other categories.

Available-for-sale financial investments are recognised at fair value plus directly related incremental transaction costs, and are subsequently carried at fair value in the statement of financial position. Changes in the fair value of available-for-sale investments are recognised directly in equity, until the investment is disposed of or is determined to be impaired. At this time the cumulative gain or loss previously recognised in equity is included in the income statement for the period. Investment income is recognised using the effective interest method and taken through interest income in the income statement.

Loans receivable and other receivables are initially recognised at fair value and subsequently held at amortised cost using the effective interest method. Interest income, together with gains and losses when the loans and receivables are derecognised or impaired, are recognised in the income statement.

Subsequent to initial recognition, the fair values of financial assets measured at fair value that are quoted in active markets are based on bid prices. When independent prices are not available, fair values are determined by using valuation techniques that are consistent with techniques commonly used by the relevant market. The techniques use observable market data.

Available-for-sale investments are recorded at fair value. Due to their short maturities the carrying value of loans and receivables approximates their fair value. The maximum exposure to credit risk at the reporting date is the fair value of the financial investments. For further information on our credit risk, refer to note 30 (a). None of the financial investments are past due or impaired.

14. Investments in joint ventures and associates

Investments in joint ventures and associates represents businesses we do not control, but instead exercise joint control or significant influence.

A joint venture is an arrangement established to engage in economic activity, which the Company jointly controls with other parties and has rights to the net assets of the arrangement. An associate is an entity that is neither a subsidiary nor a joint venture, but over which the Company has significant influence.

Outstanding balances with joint ventures and associates are shown in note 28.

15. Derivative financial instruments

Derivatives are financial instruments that derive their value from the price of an underlying item such as interest rates, foreign exchange, credit spreads, commodities, equity or other indices. In accordance with Board approved policies, derivatives are transacted to manage our exposure to fluctuations in interest rate and foreign exchange rate on borrowings and other contractual cash flows. Specifically, we use derivatives to manage these risks from our financing portfolio to optimise the overall cost of accessing the debt capital markets. These derivatives are analysed below. We also use derivatives to manage our operational market risks from commodities. The commodity derivative contracts are detailed in note 30 (e).

Derivative financial instruments are initially recognised at fair value and subsequently remeasured at fair value at each reporting date. Changes in fair values are recorded in the period they arise, either in the income statement or other comprehensive income depending on the applicable accounting standards. Where the fair value of a derivative is positive it is carried as a derivative asset, and where negative as a derivative liability.

We calculate fair value of the financial derivatives by discounting all future cash flows using the market yield curve at the reporting date. The market yield curve for each currency is obtained from external sources for interest and foreign exchange rates. In the absence of sufficient market data, fair values would be based on the quoted market price of similar derivatives. Analysis of these derivatives and the various methods used to calculate their respective fair values is detailed below and in note 30.

For each class of derivative instrument type the fair value amounts are as follows:

Inflation linked swaps										(1,391)		(1,390)

Total										(30,109)		(33,219)

The notional contract amounts of derivatives indicate the gross nominal value of transactions outstanding at the reporting date. Where possible, derivatives held as hedging instruments are formally designated as hedges as defined in IAS 39. Derivatives may qualify as hedges for accounting purposes if they are fair value hedges, cash flow hedges or net investment hedges. Our use of derivatives may entail a derivative transaction qualifying for one or more hedge type designations under IAS 39. Hedge accounting allows derivatives to be designated as a hedge of another non-derivative financial instrument, to mitigate the impact of potential volatility in the income statement of changes in the fair value of the derivative financial instruments. To qualify for hedge accounting, documentation is prepared specifying the hedging strategy, the component transactions and methodology used for effectiveness measurement. National Grid uses three hedge accounting methods, which are described as follows: Fair value hedges* Fair value hedges principally consist of interest rate and cross-currency swaps that are used to protect against changes in the fair value of fixed-rate, long-term financial instruments due to movements in market interest rates. For qualifying fair value hedges, all changes in the fair value of the derivative and changes in the fair value of the item in relation to the risk being hedged are recognised in the income statement to the extent the fair value hedge is effective. Adjustments made to the carrying amount of the hedged item for fair value hedges will be amortised over the remaining life, in line with the hedged item.
									2014 £m		2013 £m

Cross-currency interest rate/interest rate swaps										367		732

Fair value hedges										367		732

Cash flow hedges
Exposure arises from the variability in future interest and currency cash flows on assets and liabilities which bear interest at variable rates or are in a foreign currency. Interest rate and cross-currency swaps are maintained, and designated as cash flow hedges, where they qualify, to manage this exposure. Fair value changes on designated cash flow hedges are initially recognised directly in the cash flow hedge reserve, as gains or losses recognised in equity and any ineffective portion is recognised immediately in the income statement. Amounts are transferred from equity and recognised in the income statement as the income or expense is recognised on the hedged item.
Forward foreign currency contracts are used to hedge anticipated and committed future currency cash flows. Where these contracts qualify for hedge accounting they are designated as cash flow hedges. On recognition of the underlying transaction in the financial statements, the associated hedge gains and losses, deferred in equity, are transferred and included with the recognition of the underlying transaction.

15. Derivative financial instruments continued
Cash flow hedges continued
When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in equity is transferred to the income statement.
Where a non-financial asset or a non-financial liability results from a forecasted transaction or firm commitment being hedged, the amounts deferred in equity are included in the initial measurement of that non-monetary asset or liability.

Net investment hedges
Borrowings, cross-currency swaps and forward currency contracts are used in the management of the foreign exchange exposure arising from the investment in non-sterling denominated subsidiaries. Where these contracts qualify for hedge accounting they are designated as net investment hedges.

Cross-currency interest rate swaps		342		(56)
Foreign exchange forward contracts		66		(39)

Net investment hedges		408		(95)

The cross-currency swaps and forward foreign currency contracts are hedge accounted using the spot to spot method. The foreign exchange gain or loss on retranslation of the borrowings and the spot to spot movements on the cross-currency swaps and forward currency contracts are transferred to equity to offset gains or losses on translation of the net investment in the non-sterling denominated subsidiaries, with any ineffective portion recognised immediately in the income statement.
Derivatives not in a formal hedge relationship
Our policy is not to use derivatives for trading purposes. However, due to the complex nature of hedge accounting under IAS 39 some derivatives may not qualify for hedge accounting, or are specifically not designated as a hedge where natural offset is more appropriate. Changes in the fair value of any derivative instruments that do not qualify for hedge accounting are recognised in remeasurements within the income statement.

Derivatives not in a formal hedge relationship		(149)		(181)

Discontinuation of hedge accounting
Hedge accounting is discontinued when the hedging instrument expires or is sold, terminated, exercised or no longer qualifies for hedge accounting. At that time, any cumulative gains or losses relating to cash flow hedges recognised in equity are initially retained in equity and subsequently recognised in the income statement in the same periods in which the previously hedged item affects net profit or loss. Amounts deferred in equity with respect to net investment hedges are subsequently recognised in the income statement in the event of the disposal of the overseas operations concerned. For fair value hedges, the cumulative adjustment recorded to the carrying value of the hedged item at the date hedge accounting is discontinued is amortised to the income statement using the effective interest method.
Embedded derivatives
No adjustment is made with respect to derivative clauses embedded in financial instruments or other contracts that are defined as closely related to those instruments or contracts. Consequently these embedded derivatives are not accounted for separately from the debt instrument. Where there are embedded derivatives in host contracts not closely related, the embedded derivative is separately accounted for as a derivative financial instrument.

16. Inventories and current intangible assets

Inventories represent assets that we intend to use in order to generate revenue in the short term, either by selling the asset itself (for example fuel stocks) or by using it to fulfil a service to a customer or to maintain our network (consumables).

Inventories are stated at the lower of weighted average cost and net realisable value.

Where applicable, cost comprises direct materials and direct labour costs as well as those overheads that have been incurred in bringing the inventories to their present location and condition.

Emission allowances, principally relating to the emissions of carbon dioxide in the UK and sulphur and nitrous oxides in the US, are recorded as intangible assets within current assets and are initially recorded at cost and subsequently at the lower of cost and net realisable value. Where emission allowances are granted by relevant authorities, cost is deemed to be equal to the fair value at the date of allocation. Receipts of such grants are treated as deferred income, which is recognised in the income statement as the related charges for emissions are recognised or on impairment of the related intangible asset. A provision is recorded in respect of the obligation to deliver emission allowances and emission charges are recognised in the income statement in the period in which emissions are made.

17. Trade and other receivables
Trade and other receivables are amounts which are due from our customers for services (and commodities in the US) we have provided. Other receivables also include prepayments made by us, for example, property lease rentals paid in advance.
Trade, loan and other receivables are initially recognised at fair value and subsequently measured at amortised cost, less any appropriate allowances for estimated irrecoverable amounts. A provision is established for irrecoverable amounts when there is objective evidence that amounts due under the original payment terms will not be collected.

18. Cash and cash equivalents
Cash and cash equivalents includes cash balances, together with short-term investments with a maturity of less than three months that are readily convertible to cash.
Net cash and cash equivalents reflected in the cash flow statement are net of bank overdrafts, which are reported in borrowings. The carrying amounts of cash and cash equivalents and bank overdrafts approximate their fair values.
Cash at bank earns interest at floating rates based on daily bank deposit rates. Short-term deposits are made for periods varying between one day and three months, depending on the immediate cash requirements, and earn interest at the respective short-term deposit rates.
Net cash and cash equivalents held in currencies other than sterling have been converted into sterling at year-end exchange rates.
For further information on currency exposures, refer to note 30 (d).

19. Borrowings
We borrow money primarily in the form of bonds and bank loans. These are for a fixed term and may have fixed or floating interest rates or are linked to RPI. As indicated in note 15, we use derivatives to manage risks associated with interest rates and foreign exchange.
Our strategy in action
Our price controls and rate plans require us to fund our networks within a certain ratio of debt to equity and, as a result, we have issued a significant amount of debt. As we continue to invest in our networks, the level of debt is expected to increase over time. To maintain a strong balance sheet and to allow us to access capital markets at commercially acceptable interest rates, we balance the amount of debt we issue with the value of our assets and take account of certain other metrics used by credit rating agencies.
Borrowings, which include interest-bearing and inflation linked debt and overdrafts are recorded at their initial fair value which normally reflects the proceeds received, net of direct issue costs less any repayments. Subsequently these are stated at amortised cost, using the effective interest method. Any difference between the proceeds after direct issue costs and the redemption value is recognised over the term of the borrowing in the income statement using the effective interest method.
The Finance Committee controls refinancing risk by limiting the amount of our debt maturities arising from borrowings in any one year which is demonstrated by our maturity profile.

The fair value of borrowings at 31 March 2014 was £28,131m (2013: £30,792m). Where market values were available, fair value of borrowings (Level 1) was £17,388m (2013: £20,543m). Where market values were not available, fair value of borrowings (Level 2) was £10,743m (2013: £10,249m), calculated by discounting cash flows at prevailing interest rates. The notional amount outstanding of the debt portfolio at 31 March 2014 was £25,539m (2013: £27,391m).
The assets of the Colonial Gas Company and the Niagara Mohawk Power Corporation and certain gas distribution assets of the Narragansett Electric Company are subject to liens and other charges and are provided as collateral over borrowings totalling £438m at 31 March 2014 (2013: £512m).
Collateral is placed with or received from any counterparty where we have entered into a credit support annex to the ISDA Master Agreement once the current mark-to-market valuation of the trades between the parties exceeds an agreed threshold. Included in current bank loans is £843m (2013: £730m) in respect of cash received under collateral agreements. For further details of our borrowing facilities, refer to note 31. For further details of our bonds in issue, please refer to the debt investor section of our website.
Assets held under finance leases are recognised at their fair value or, if lower, the present value of the minimum lease payments on inception. The corresponding liability is recognised as a finance lease obligation within borrowings. Rental payments are apportioned between finance costs and reduction in the finance lease obligation, so as to achieve a constant rate of interest.
Assets held under finance leases are depreciated over the shorter of their useful life and the lease term.

Unaudited commentary on borrowings

As at 31 March 2014, total borrowings of £25,950m (2013: £28,095m) including bonds, bank loans, commercial paper, collateral, finance leases and other debt had decreased by £2,145m primarily representing maturity and redemption of debt during the year. We expect to repay £3,511m of our total borrowings in the next 12 months including commercial paper, collateral and interest, and we expect to be able to refinance this borrowing through the capital and money markets.

The maturity profile of long-term debt in our major entities is illustrated below:

20. Trade and other payables
Trade and other payables includes amounts owed to suppliers, tax authorities and other parties which are due to be settled within 12 months. The total also includes deferred income, which represents monies received from customers but for which we have not yet completed the associated service. These amounts are recognised as revenue when the service is provided.
Trade payables are initially recognised at fair value and subsequently measured at amortised cost.

Trade payables		1,942		2,033

Commodity contract liabilities		77		69
Social security and other taxes		146		131
Other payables		642		663

		3,031		3,051

Due to their short maturities, the fair value of trade and other payables approximates their book value. Commodity contract liabilities are recorded at fair value. All other trade and other payables are recorded at amortised cost.
21. Other non-current liabilities
Other non-current liabilities includes deferred income which will not be recognised as income until after 31 March 2015. It also includes payables that are not due until after that date.

	2014		2013

Deferred income		1,605		1,579
Commodity contract liabilities		46		70
Other payables		190		235

		1,841		1,884

Commodity contract liabilities are recorded at fair value. All other non-current liabilities are recorded at amortised cost. There is no material difference between the fair value and the carrying value of other non-current liabilities.
22. Pensions and other post-retirement benefits
Substantially all our employees are members of either DB or DC pension plans. The principal UK plans are the National Grid UK Pension Scheme, the National Grid Electricity Group of the Electricity Supply Pension Scheme and The National Grid YouPlan. In the US, we have a number of plans and also provide healthcare and life insurance benefits to eligible retired US employees.
The fair value of associated plan assets and present value of DB obligations are updated annually. For further details and the actuarial assumptions used to value the obligations, see note 29.
With the adoption of IAS 19 (revised), we have increased our disclosures by separately presenting our UK and US pension plans to show geographical split.
Below we provide a more detailed analysis of the amounts recorded in the primary financial statements.
For DC plans, the Group pays contributions into separate funds on behalf of the employee and has no further obligations to employees. The risks associated with this type of plan are assumed by the member.
For DB retirement plans, members receive benefits on retirement, the value of which is dependent on factors such as salary and length of pensionable service. The Group underwrites both financial and demographic risks associated with this type of plan.
The cost of providing benefits in a DB plan is determined using the projected unit method, with actuarial valuations being carried out at each reporting date by a qualified actuary. This valuation method is an accrued benefits valuation method that makes allowance for projected earnings.
The Group’s obligation in respect of DB pension plans is calculated separately for each plan by projecting the estimated amount of future benefit payments that employees have earned for their pensionable service in the current and prior periods. These future benefit payments are discounted to determine the present value of the liabilities and the fair value of plan assets and any unrecognised past service cost is then deducted. The discount rate used is the yield at the valuation date on high-quality corporate bonds.

22. Pensions and other post-retirement benefits continued
The Group takes advice from independent actuaries relating to the appropriateness of any key assumptions applied which include life expectancy of members, expected salary and pension increases, and inflation. It should be noted that comparatively small changes in the assumptions used may have a significant effect on the amounts recognised in the income statement and the statement of other comprehensive income and the net liability recognised in the statement of financial position.
Remeasurements of net retirement obligations are recognised in full in the period in which they occur in the statement of other comprehensive income.
Risks
The DB pension obligations and other post-retirement benefit liabilities are exposed to the primary risks outlined below.
Liabilities are calculated using discount rates set with reference to yields on high-quality corporate bonds prevailing in the US and UK debt markets and will fluctuate as yields change. Plan funds are invested in a variety of asset classes, principally: equities, government securities, corporate bonds and property. Consequently, actual returns will differ from the underlying discount rate adopted and therefore have an impact on the net balance sheet liability.
Changes in inflation will affect both current and future pension payments and are partially mitigated through investment in inflation matching assets and hedging instruments.
Longevity is also a key driver of liabilities and changes in expected mortality will have a direct impact on liabilities. The liabilities are, in aggregate, relatively mature which serves to mitigate this risk to some extent.
Each plan’s investment strategy seeks to balance the level of investment return sought with the aim of reducing volatility and risk. In undertaking this approach reference is made both to the maturity of the liabilities and the funding level of that plan. A number of further strategies are employed to manage underlying risks, including liability matching asset strategies, diversification of asset portfolios, interest rate hedging and active management of foreign exchange exposure.

23. Provisions
We make provisions when an obligation exists, resulting from a past event and it is probable that cash will be paid to settle it, but the exact amount of cash required can only be estimated. The main estimates relate to environmental remediation and decommissioning costs for various sites we own or have owned and other provisions, including restructuring plans and lease contracts we have entered into that are now loss making. Our strategy in action We are committed to the protection and enhancement of the environment. However, we have acquired, owned and operated a number of businesses which have, during the course of their operations, created an environmental impact. Therefore we have a provision that reflects the expected cost to remediate these sites. Current operations will seldom result in new sites with significant expected costs being added to the provision.
Provisions are recognised where a legal or constructive obligation exists at the reporting date, as a result of a past event, where the amount of the obligation can be reliably estimated and where the outflow of economic benefit is probable. Provision is made for decommissioning and environmental costs, based on future estimated expenditures, discounted to present values. An initial estimate of decommissioning and environmental costs attributable to property, plant and equipment is recorded as part of the original cost of the related property, plant and equipment. Changes in the provision arising from revised estimates or discount rates or changes in the expected timing of expenditures that relate to property, plant and equipment are recorded as adjustments to their carrying value and depreciated prospectively over their remaining estimated useful economic lives; otherwise such changes are recognised in the income statement. The unwinding of the discount is included within the income statement as a financing charge.

1. The remediation expenditure in the UK relates to old gas manufacturing sites and also to electricity transmission sites. Cash flows are expected to be incurred between 2014 and 2067. A number of uncertainties affect the calculation of the provision, including the impact of regulation, accuracy of the site surveys, unexpected contaminants, transportation costs, the impact of alternative technologies and changes in the discount rate. This provision incorporates our best estimate of the financial effect of these uncertainties, but future material changes in any of the assumptions could have a material impact on the calculation of the provision. The undiscounted amount is the undiscounted best estimate of the liability having regard to these uncertainties.

2. The remediation expenditure in the US is expected to be incurred between 2014 and 2059. The uncertainties regarding the calculation of this provision are similar to those considered in respect of UK sites. However, unlike the UK, with the exception of immaterial amounts of such costs, this expenditure is expected to be largely recoverable from ratepayers under the terms of various rate agreements in the US.

Decommissioning provision

The decommissioning provision primarily represents both £55m (2013: £69m) of expenditure relating to asset retirement obligations expected to be incurred until 2058, and £72m (2013: £nil) of expenditure relating to the demolition of gas holders expected to be incurred until 2022. It also includes the net present value of the estimated expenditure (discounted at a real rate of 2%) expected to be incurred until 2038 in respect of the decommissioning of certain US nuclear generating units that National Grid no longer owns.

Restructuring provision

The restructuring provision principally relates to business reorganisation costs in the UK and the US and is expected to be incurred until 2021.

Emissions provision

The provision for emission costs is expected to be settled using emission allowances granted.

Other provisions

Included within other provisions at 31 March 2014 are amounts provided in respect of onerous lease commitments and rates payable on surplus properties of £117m (2013: £165m) with expenditure expected to be incurred until 2018.

Other provisions also include £160m (2013: £174m) of estimated liabilities in respect of past events insured by insurance subsidiary undertakings, including employer liability claims. In accordance with insurance industry practice, these estimates are based on experience from previous years and there is, therefore, no identifiable payment date. It also includes £13m (2013: £13m) in respect of obligations associated with investments in joint ventures.

24. Share capital
Ordinary share capital represents the total number of shares issued which are publicly traded. We also disclose the number of treasury shares the Company holds, which are shares that the Company has bought itself, predominantly to satisfy employee share option plan liabilities.
Share capital is accounted for as an equity instrument. An equity instrument is any contract that includes a residual interest in the consolidated assets of the Company after deducting all its liabilities and is recorded at the proceeds received, net of direct issue costs, with an amount equal to the nominal amount of the shares issued included in the share capital account and the balance recorded in the share premium account.

1. The issue of shares in lieu of dividends is considered to be a bonus issue under the terms of the Companies Act 2006 and the nominal value of the shares is charged to the share premium account. The share capital of the Company consists of ordinary shares of 11¹⁷⁄₄₃ pence nominal value each including ADSs. The ordinary and ADSs allow holders to receive dividends and vote at general meetings 43 of the Company. The Company holds treasury shares but may not exercise any rights over these shares including the entitlement to vote or receive dividends. There are no restrictions on the transfer or sale of ordinary shares. In line with the provisions of the Companies Act 2006, the Company has amended its Articles of Association and ceased to have authorised share capital. Treasury shares At 31 March 2014, the Company held 124m (2013: 129m) of its own shares. The market value of these shares as at 31 March 2014 was £1,019m (2013: £989m). The maximum number of shares held during the year was 129m ordinary shares (2013: 135m) representing approximately 3.4% (2013: 3.6%) of the ordinary shares in issue as at 31 March 2014 and having a nominal value of £15m (2013: £15m).

25. Other equity reserves
Other equity reserves are different categories of equity as required by accounting standards and represent the impact of a number of our historical transactions.
Other equity reserves comprise the translation reserve (see accounting policy B), cash flow hedge reserve (see note 15), available-for-sale reserve (see note 13), the capital redemption reserve and the merger reserve. The merger reserve arose as a result of the application of merger accounting principles under the then prevailing UK GAAP, which under IFRS 1 was retained for mergers that occurred prior to the IFRS transition date. Under merger accounting principles, the difference between the carrying amount of the capital structure of the acquiring vehicle and that of the acquired business was treated as a merger difference and included within reserves. As the amounts included in other equity reserves are not attributable to any of the other classes of equity presented, they have been disclosed as a separate classification of equity.

The merger reserve represents the difference between the carrying value of subsidiary undertaking investments and their respective capital structures following the Lattice demerger from BG Group plc and the 1999 Lattice refinancing of £5,745m and merger differences of £221m and £359m. The cash flow hedge reserve on interest rate swap contracts will be continuously transferred to the income statement until the borrowings are repaid. The amount due to be released from reserves to the income statement next year is £17m (pre-tax) and the remainder released with the same maturity profile as borrowings due after more than one year.

26. Net debt
Net debt represents the amount of borrowings and overdrafts, less cash, financial investments and related derivatives.
Funding and liquidity risk management is carried out by the treasury function under policies and guidelines approved by the Finance Committee of the Board. The Finance Committee is responsible for the regular review and monitoring of treasury activity and for the approval of specific transactions, the authority for which falls outside the delegation of authority to management. The primary objective of the treasury function is to manage our funding and liquidity requirements. A secondary objective is to manage the associated financial risks, in the form of interest rate risk and foreign exchange risk, to within pre-authorised parameters. Details of the main risks arising from our financing and commodity hedging activities can be found in the risk factors discussion starting on page 167 and in note 30 to the consolidated financial statements on pages 137 to 144. Investment of surplus funds, usually in short-term fixed deposits or placements with money market funds that invest in highly liquid instruments of high credit quality, is subject to our counterparty risk management policy.

– supplementary information


This section includes information that is important to enable a full understanding of our financial position, particularly areas of potential risk that could affect us in the future. We also include specific disclosures for British Transco Finance Inc., Niagara Mohawk Power Corporation and National Grid Gas plc in accordance with various rules including Rule 3-10 of Regulation S-X (a US SEC requirement), as they have issued public debt securities which have been guaranteed by National Grid plc and one of its subsidiary companies, National Grid Gas plc. Additional disclosures have also been included in respect of the two guarantor companies. These disclosures are in lieu of publishing separate financial statements for these companies. See note 34 for further information.
27. Commitments and contingencies
Commitments are those amounts that we are contractually required to pay in the future as long as the other party meets its obligations. These commitments primarily relate to operating lease rentals, energy purchase agreements and contracts for the repurchase of network assets which, in many cases, extend over a long period of time. We also disclose any contingencies, which include guarantees that companies have given, where we pledge assets against obligations that will remain for a specific period.

1. Energy purchase commitments relate to contractual commitments to purchase electricity or gas that are used to satisfy physical delivery requirements to our customers or for energy that we use ourselves (ie normal purchase, sale or usage) and hence are accounted for as ordinary purchase contracts. Details of commodity contracts that do not meet the normal purchase, sale or usage criteria, and hence are accounted for as derivative contracts, are shown in note 30 (e) on page 142. The total of future minimum sublease payments expected to be received under non-cancellable subleases is £21m (2013: £23m). Through the ordinary course of our operations, we are party to various litigation, claims and investigations. We do not expect the ultimate resolution of any of these proceedings to have a material adverse effect on our results of operations, cash flows or financial position.

29. Actuarial information on pensions and other post-retirement benefits

Further details of the DB plans terms and the actuarial assumptions used to value the obligations are set out in this note.

When deciding on these assumptions we take independent actuarial advice. Comparatively small changes in the assumptions applied may have a significant effect on the overall deficit or surplus of a DB plan.

UK pension plans

National Grid’s DB pension arrangements are funded with assets held in separate trustee administered funds. The arrangements are managed by trustee companies with boards consisting of company and member appointed directors. The directors are required to manage the arrangements in accordance with local regulations and the arrangements’ governing documents, acting on behalf of its beneficiaries.

The arrangements are subject to independent actuarial funding valuations at least every three years and following consultation and agreement with us, the qualified actuary certifies the employers’ contribution, which, together with the specified contributions payable by the employees and proceeds from the plans’ assets, are expected to be sufficient to fund the benefits payable. The last full actuarial valuations were carried out as at 31 March 2010. The 2013 valuations are ongoing and are expected to be agreed by the end of June.

The results of the 2010 valuations are shown below:

Following consultations during the past year with affected employees and our trade union partners, and the positive outcome of trade union ballots, National Grid, working with the Trustees, will implement changes to the benefits provided by its two UK DB pension schemes from 1 April 2014. From April 2014 an annual cap will be placed on future increases to the salary used to calculate pensions at the lower of 3% or the annual increase in RPI. This capped salary will apply to all pensionable service from 1 April 2013 onwards. These changes have resulted in a past service credit of £11m to the income statement (see note 22) and a change to the salary increase assumption which affects how our DB liabilities as at 31 March 2014 have been calculated.

The aim of these changes is to ensure our Schemes remain affordable and sustainable over the coming years.

National Grid UK Pension Scheme

The 2010 actuarial funding valuation showed that, based on long-term financial assumptions, the contribution rate required to meet future benefit accrual was 35% of pensionable earnings (32% by employers and 3% by employees). In addition, National Grid makes payments to the scheme to cover administration costs and the Pension Protection Fund levy. The employer contribution rate and administration costs are being reviewed as part of the 2013 valuation.

Following the 2010 valuation, National Grid and the Trustees agreed a recovery plan which would see the funding deficit repaid by 31 March 2027. Under the schedule of contributions, no deficit contributions were made in 2010/11 or 2011/12. Annual payments of £47m, rising in line with the RPI from March 2010, commenced in 2012/13 and (subject to the current valuation discussions) are due to continue until 2027. As part of the initial 2013 valuation discussions with the Trustees an additional payment of £6m was paid in March 2014.

As part of the 2010 agreement, National Grid has established security account arrangements with a charge in favour of the Trustees. The value of the assets in the security account at 31 March 2014 was approximately £199m. The assets in the security account will be paid to the scheme in the event that National Grid Gas plc (NGG) is subject to an insolvency event, or is given notice of less than 12 months that Ofgem intends to revoke its licence under the Gas Act 1986. The assets in the security account will be released back to National Grid if the scheme moves into surplus.

This scheme ceased to allow new hires to join from 1 April 2002. A DC section of the scheme was offered for employees joining after this date, which closed to future contributions on 31 October 2013 and was replaced by The National Grid YouPlan (see below).

National Grid Electricity Group of the Electricity Supply Pension Scheme

The 2010 actuarial funding valuation showed that, based on long-term financial assumptions, the contribution rate required to meet future benefit accrual was 29.6% of pensionable earnings (23.7% by employers and an average of 5.9% by employees). The employer contribution rate is being reviewed as part of the 2013 valuation.

Following the 2010 valuation, National Grid and the Trustees agreed a recovery plan that would see the funding deficit repaid by 31 March 2027. Under the schedule of contributions, payments of £45m were made in 2010/11 and 2011/12 and a further payment of £38m was made in 2012/13. Thereafter annual payments of £38m rising in line with RPI are due to continue until 2027. The actual payment made in 2013/14 was £45m which included an additional payment of £7m following initial 2013 valuation discussions with the Trustees. A further £35m paid in 2011/12 to support a de-risking initiative has been recognised from a funding perspective during 2013/14.

As part of this agreement, National Grid has established security account arrangements with a charge in favour of the Trustees. The value of the assets in the security account at 31 March 2014 was approximately £35m. The assets in the security account will be paid to the scheme in the event that National Grid Electricity Transmission plc (NGET) is subject to an insolvency event, or ceases to hold a licence granted under the Electricity Act 1989. The assets in the security account will be released back to National Grid if the scheme moves into surplus.

National Grid has also agreed to make a payment in respect of the deficit up to a maximum of £220m should certain triggers be breached; namely if NGET ceases to hold the licence granted under the Electricity Act 1989 or NGET’s credit rating by two out of three specified agencies falls below certain agreed levels for a period of 40 days.

The scheme closed to new members from 1 April 2006.

The National Grid YouPlan

Following a review of the DC section of the National Grid UK Pension Scheme, National Grid established a new DC trust, The National Grid YouPlan (YouPlan). This was launched on 1 November 2013 and future contributions for active members of the DC section were paid to YouPlan from this date.

Under the rules of the plan, National Grid double matches contributions to YouPlan currently up to a maximum of 5% of employee salary. Member accounts built up in the DC section prior to 1 November 2013 will be transferred to YouPlan in 2014.

YouPlan is the qualifying scheme used for automatic enrolment and National Grid’s staging date was 1 April 2013. All new hires are enrolled into YouPlan.

US pension plans

National Grid’s DB pension plans in the US provide annuity or lump sum payments for vested employees. Non-union employees hired on or after 1 January 2011 are provided with a core contribution into the DC plan, irrespective of the employee’s contribution to the plan. A core contribution in the DC plan is also provided to new hires in ten groups of represented US employees. In addition, an employer match is offered to eligible employees in the DC plan on their elective deferrals into the plan. The assets of the plans are held in separate trusts and administered by the fiduciary committees.

Employees do not contribute to the DB pension plans. Employer contributions are made in accordance with the rules set forth by the US Internal Revenue Code and can vary according to the funded status of the plans and the amounts that are tax deductible. At present, there is some flexibility in the amount that is contributed on an annual basis. In general, the Company’s policy for funding the US pension plans is to contribute amounts collected in rates and capitalised in the rate bases during the year. These contributions will be no less than the amounts needed to meet the requirements of the Pension Protection Act of 2006.

29. Actuarial information on pensions and other post-retirement benefits continued US retiree healthcare and life insurance plans National Grid provides healthcare and life insurance benefits to eligible retired US employees. Eligibility is based on certain age and length of service requirements and in most cases retirees contribute to the cost of their healthcare coverage. In the US, there is no governmental requirement to pre-fund post-retirement health and welfare plans. However, in general, the Company’s policy for funding the US retiree healthcare and life insurance plans is to contribute amounts collected in rates and capitalised in the rate bases during the year.

1.	The discount rates for pension liabilities have been determined by reference to appropriate yields on high-quality corporate bonds prevailing in the UK and US debt markets at the reporting date.
2.	A promotional scale has also been used where appropriate. The UK assumption stated is that relating to service prior to 1 April 2013. The UK assumption for the rate of increase in salaries for service after this date is 2.5%.
3.	This is the key assumption that determines assumed increases in pensions in payment and deferment in the UK only. The assumptions for the UK were 3.3% (2013: 3.4%; 2012: 3.2%) for increases in pensions in payment and 3.3% (2013: 3.4%; 2012: 3.2%) for increases in pensions in deferment.

30. Financial risk management
Our activities expose us to a variety of financial risk including currency risk, interest rate risk, commodity price risk, credit risk, capital risk and liquidity risk. Our risk management programme focuses on the unpredictability of financial markets and seeks to minimise potential volatility of financial performance of these risks. We use financial instruments, including derivative financial instruments, to manage risks of this type. This note describes our approach to managing risk, including an analysis of assets and liabilities by currency type and an analysis of interest rate category for our net debt. We are required by accounting standards to also include a number of specific disclosures (such as a maturity analysis of contractual undiscounted cash flows) and have included these requirements below.
Risk management related to financing activities is carried out by a central treasury department under policies approved by the Finance Committee of the Board. The objective of the treasury department is to manage funding and liquidity requirements, including managing associated financial risks, to within acceptable boundaries. The Finance Committee provides written principles for overall risk management, as well as written policies covering specific areas such as foreign exchange risk, interest rate risk, credit risk, liquidity risk, use of derivative financial instruments and non-derivative financial instruments, and investment of excess liquidity. We have exposure to the following risks, which are described in more detail below: — credit risk; — liquidity risk; — interest rate risk; — currency risk; — commodity risk; and — capital risk (a) Credit risk We are exposed to the risk of loss resulting from counterparties’ default on their commitments including failure to pay or make a delivery on a contract. This risk is inherent in our commercial business activities. We are exposed to credit risk on our cash and cash equivalents, derivative financial instruments, deposits with banks and financial institutions, as well as credit exposures to wholesale and retail customers, including outstanding receivables and committed transactions. Treasury credit risk Counterparty risk arises from the investment of surplus funds and from the use of derivative instruments. As at 31 March 2014, the following limits were in place for investments held with banks and financial institutions:
	Maximum limit		Long-term limit
	£m		£m

AAA rated G8 sovereign entities		Unlimited		Unlimited
Triple ‘A’ vehicles		311		263
Triple ‘A’ range institutions (AAA)		1,060 to 1,599		534 to 837
Double ‘A’ range institutions (AA)		633 to 797		322 to 398
Single ‘A’ range institutions (A)		218 to 311		111 to 159

As at 31 March 2013 and 2014, we had a number of exposures to individual counterparties. In accordance with our treasury policies, counterparty credit exposure utilisations are monitored daily against the counterparty credit limits. Counterparty credit ratings and market conditions are reviewed continually with limits being revised and utilisation adjusted, if appropriate. Management does not expect any significant losses from non performance by these counterparties. Commodity credit risk The credit policy for commodity transactions is owned and monitored by the Executive Energy Risk Committee, under authority delegated by the Board and Executive Committee, and establishes controls and procedures to determine, monitor and minimise the credit risk of counterparties. Wholesale and retail credit risk Our principal commercial exposure in the UK is governed by the credit rules within the regulated codes Uniform Network Code and Connection and Use of System Code. These set out the level of credit relative to the RAV for each credit rating. In the US, we are required to supply electricity and gas under state regulations. Our credit policies and practices are designed to limit credit exposure by collecting security deposits prior to providing utility services, or after utility service has commenced if certain applicable regulatory requirements are met. Collection activities are managed on a daily basis. Sales to retail customers are usually settled in cash, cheques, electronic bank payments or by using major credit cards. We are committed to measuring, monitoring, minimising and recording counterparty credit risk in our wholesale business. The utilisation of credit limits is regularly monitored and collateral is collected against these accounts when necessary. Management does not expect any significant losses of receivables that have not been provided for as shown in note 17.

30. Financial risk management continued (a) Credit risk continued Offsetting financial assets and liabilities The following tables set out our financial assets and liabilities which are subject to offset and to enforceable master netting arrangements or similar agreements. The tables show the amounts which are offset and reported net in the statement of financial position. Amounts which cannot be offset under IFRS, but which could be settled net under terms of master netting agreements if certain conditions arise, and with collateral received or pledged, are shown to present National Grid’s net exposure. Financial assets and liabilities on different transactions are only reported net if the transactions are with the same counterparty, a legal right of offset exists and the cash flows are intended to be settled on a net basis. Amounts which do not meet the criteria for offsetting on the statement of financial position but could be settled net in certain circumstances principally relate to derivative transactions under ISDA (International Swaps and Derivatives Association) agreements where each party has the option to settle amounts on a net basis in the event of default of the other party. Commodity contracts that have not been offset on the balance sheet may be settled net in certain circumstances under ISDA or NAESB (North American Energy Standards Board) agreements. National Grid has similar arrangements in relation to bank account balances and bank overdrafts; and trade payables and trade receivables which are subject to general terms and conditions. However, these balances are immaterial.

30. Financial risk management continued (b) Liquidity risk Our policy is to determine our liquidity requirements by the use of both short-term and long-term cash flow forecasts. These forecasts are supplemented by a financial headroom analysis which is used to assess funding requirements for at least a 24 month period and maintain adequate liquidity for a continuous 12 month period. We believe our contractual obligations, including those shown in commitments and contingencies in note 27 can be met from existing cash and investments, operating cash flows and other financings that we reasonably expect to be able to secure in the future, together with the use of committed facilities if required. Our debt agreements and banking facilities contain covenants, including those relating to the periodic and timely provision of financial information by the issuing entity and financial covenants such as restrictions on the level of subsidiary indebtedness. Failure to comply with these covenants, or to obtain waivers of those requirements, could in some cases trigger a right, at the lender’s discretion, to require repayment of some of our debt and may restrict our ability to draw upon our facilities or access the capital markets. The following is an analysis of the contractual undiscounted cash flows payable under financial liabilities and derivative assets and liabilities as at the reporting date:

(c) Interest rate risk

National Grid’s interest rate risk arises from our long-term borrowings. Borrowings issued at variable rates expose National Grid to cash flow interest rate risk, partially offset by cash held at variable rates. Borrowings issued at fixed rates expose National Grid to fair value interest rate risk.

Our interest rate risk management policy is to seek to minimise total financing costs (being interest costs and changes in the market value of debt) subject to constraints. We do this by using fixed and floating rate debt and derivative financial instruments including interest rate swaps, swaptions and forward rate agreements.

We hold some borrowings on issue that are inflation linked. We believe that these provide a partial economic offset to the inflation risk associated with our UK inflation linked revenues.

The table in note 19 sets out the carrying amount, by contractual maturity, of borrowings that are exposed to interest rate risk before taking into account interest rate swaps.

During 2014 and 2013, net debt was managed using derivative instruments to hedge interest rate risk as follows:

Includes bank overdrafts.

The impact of 2014/15 (2013: 2013/14) maturing short-dated interest rate derivatives is included.

(d) Currency risk

National Grid operates internationally and is exposed to foreign exchange risk arising from various currency exposures, primarily with respect to the dollar. Foreign exchange risk arises from future commercial transactions, recognised assets and liabilities, and investments in foreign operations.

Our policy for managing foreign exchange transaction risk is to hedge contractually committed foreign currency cash flows over a prescribed minimum size. Where foreign currency cash flow forecasts are less certain, our policy is to hedge a proportion of such cash flows based on the probability of those cash flows occurring. Instruments used to manage foreign exchange transaction risk include foreign exchange forward contracts and foreign exchange swaps.

Our policy for managing foreign exchange translation risk relating to our net investment in foreign operations is to maintain a percentage of net debt and foreign exchange forwards so as to provide an economic offset of our cash flows arising in the foreign currency. The primary managed foreign exchange exposure arises from the dollar denominated assets and liabilities held by our US operations, with a further small euro exposure in respect of a joint venture investment.

During 2014 and 2013, derivative financial instruments were used to manage foreign currency risk as follows:

The carrying amounts of other financial instruments are denominated in the above currencies, which in most instances are the functional currency of the respective subsidiaries. Our exposure to dollars is due to activities in our US subsidiaries. We do not have any other significant exposure to currency risk on these balances.

(e) Commodity risk

We purchase electricity and gas to supply our customers in the US and to meet our own energy needs. Substantially all our costs of purchasing electricity and gas for supply to customers are recoverable at an amount equal to cost. The timing of recovery of these costs can vary between financial periods leading to an under- or over-recovery within any particular year, that can lead to large fluctuations in the income statement. We follow approved policies to manage price and supply risks for our commodity activities.

Our energy procurement risk management policy and delegations of authority govern our US commodity trading activities for energy transactions. The purpose of this policy is to ensure we transact within pre-defined risk parameters and only in the physical and financial markets where we or our customers have a physical market requirement. In addition, state regulators require National Grid to manage commodity risk and cost volatility prudently through diversified pricing strategies. In some jurisdictions we are required to file a plan outlining our strategy to be approved by regulators. In certain cases we might receive guidance with regard to specific hedging limits.

Energy purchase contracts for the forward purchase of electricity or gas that are used to satisfy physical delivery requirements to customers or for energy that the Company uses itself meet the normal purchase, sale or usage exemption of IAS 39. They are, therefore, not recognised in the financial statements. Disclosure of commitments under such contracts is made in note 27.

We enter into forward contracts for the purchase of commodities, some of which do not meet the own use exemption for accounting purposes and hence are accounted for as derivatives. We also enter into derivative financial instruments linked to commodity prices, including index-linked futures, swaps and options contracts. These derivative financial instruments are used to manage market price volatility and are carried at fair value on the statement of financial position, with the mark-to-market changes reflected through earnings.

2.	Forward gas purchases have terms up to five years. The contractual obligations under these contracts are £171m (2013: £119m).
3.	NYMEX gas futures have been offset with related margin accounts (see note 30 (a) on page 137).
(f) Capital risk management National Grid’s objectives when managing capital are: to safeguard our ability to continue as a going concern; to remain within regulatory constraints of our regulated operating companies; and to maintain an efficient mix of debt and equity funding thus achieving an optimal capital structure and cost of capital. We regularly review and maintain or adjust the capital structure as appropriate in order to achieve these objectives. Maintaining appropriate credit ratings for our regulated companies is an important aspect of our capital risk management strategy and balance sheet efficiency. We monitor our balance sheet efficiency using several metrics including our interest cover. Interest cover for the year ended 31 March 2014 was 4.1 (2013: 3.9). Our long-term target range for interest cover is greater than 3.0, which we believe is consistent with single A range long-term senior unsecured debt credit ratings within our main UK operating companies, NGET and NGG, based on guidance from the rating agencies. In addition, we monitor the RAV gearing within each of NGET and the regulated transmission and distribution businesses within NGG. This is calculated as net debt expressed as a percentage of RAV, and indicates the level of debt employed to fund our UK regulated businesses. It is compared with the level of RAV gearing indicated by Ofgem as being appropriate for these businesses, at around 60-65%.

(f) Capital risk management continued

The majority of our regulated operating companies in the US and the UK (and one intermediate UK holding company), which are all consolidated subsidiaries of National Grid, are subject to certain restrictions on the payment of dividends by administrative order (by regulators relevant to the individual company), contract and/or licence. The types of restrictions that a company may have that would prevent a dividend being declared or paid unless they are met include:

— dividends must be approved in advance by the relevant US state regulatory commission;

— the subsidiary must have at least two recognised rating agency credit ratings of at least investment grade;

— dividends must be limited to cumulative retained earnings, including pre-acquisition retained earnings;

— National Grid plc must maintain an investment grade credit rating and if that rating is the lowest investment grade bond rating it cannot have a negative watch/review downgrade notice by a credit rating agency;

— the subsidiary must not carry on any activities other than those permitted by the licences;

— the subsidiary must not create any cross-default obligations or give or receive any intra-group cross-subsidies; and

— the percentage of equity compared with total capital of the subsidiary must remain above certain levels.

There is a further restriction relating only to the Narragansett Electric Company, which is required to maintain its consolidated net worth above certain levels.

These restrictions are subject to alteration in the US as and when a new rate case or rate plan is agreed with the relevant regulatory bodies for each operating company and in the UK through the normal licence review process.

As most of our business is regulated, at 31 March 2014 the majority of our net assets are subject to some of the restrictions noted above. These restrictions are not considered to be significantly onerous, nor do we currently expect they will prevent the planned payment of dividends in future in line with our dividend policy.

Some of our regulatory and bank loan agreements additionally impose lower limits for the long-term credit ratings that certain companies within the Group must hold. All the above requirements are monitored on a regular basis in order to ensure compliance. The Company has complied with all externally imposed capital requirements to which it is subject.

(g) Fair value analysis

The financial instruments included on the statement of financial position are measured at fair value. These fair values can be categorised into hierarchy levels that are representative of the inputs used in measuring the fair value. The best evidence of fair value is a quoted price in an actively traded market. In the event that the market for a financial instrument is not active, a valuation technique is used.

30. Financial risk management continued (g) Fair value analysis continued Our level 3 derivative financial instruments include cross-currency swaps with an embedded call option, currency swaps where the currency forward curve is illiquid and inflation linked swaps where the inflation curve is illiquid. In valuing these instruments a third-party valuation is obtained to support each reported fair value. Our level 3 commodity contracts primarily consist of our forward purchases of electricity and gas where pricing inputs are unobservable, as well as other complex transactions. Complex transactions can introduce the need for internally developed models based on reasonable assumptions. Industry standard valuation techniques such as the Black-Scholes pricing model and Monte Carlo simulation are used for valuing such instruments. Level 3 is also applied in cases when optionality is present or where an extrapolated forward curve is considered unobservable. All published forward curves are verified to market data; if forward curves differ from market data by 5% or more they are considered unobservable. The changes in value of our level 3 derivative financial instruments are as follows:

31. Borrowing facilities
To support our long-term liquidity requirements and provide backup to commercial paper and other borrowings, we agree loan facilities with financial institutions over and above the value of borrowings that may be required. These facilities have never been drawn, and our undrawn amounts are listed below.
At 31 March 2014, we had bilateral committed credit facilities of £2,073m (2013: £2,009m). In addition, we had committed credit facilities from syndicates of banks of £800m at 31 March 2014 (2013: £877m). All committed credit facilities were undrawn in 2014 and 2013. An analysis of the maturity of these undrawn committed facilities is shown below:
	2014 £m	2013 £m

Undrawn committed borrowing facilities expiring:
Less than 1 year	–	–

In 4-5 years	1,220	869

	2,873	2,886

Of the unused facilities at 31 March 2014, £2,583m (2013: £2,568m) was held as backup to commercial paper and similar borrowings, while £290m (2013: £318m) is available as backup to specific US borrowings. Further information on our bonds can be found on the debt investor section of our website.

33. Sensitivities on areas of estimation and uncertainty
In order to give a clearer picture of the impact on our results or financial position of potential changes in significant estimates and assumptions, the following sensitivities are presented. These sensitivities are hypothetical, as they are based on assumptions and conditions prevailing at the year end, and should be used with caution. The effects provided are not necessarily indicative of the actual effects that would be experienced because our actual exposures are constantly changing.
The sensitivities in the table below show the potential impact in the income statement (and consequential impact on net assets) for a range of different variables which each have been considered in isolation (ie with all other variables remaining constant). There are a number of these sensitivities which are mutually exclusive and therefore if one were to happen, another would not, meaning a total showing how sensitive our results are to these external factors is not meaningful. We are further required to show additional sensitivity analysis for changes in interest and exchange rates and these are shown separately in the table below due to the additional assumptions that are made in order to produce meaningful sensitivity disclosures. The sensitivities included in the table below all have an equal and opposite effect if the sensitivity increases or decreases by the same amount unless otherwise stated. For example a 10% increase in unbilled revenue at 31 March 2014 would result in a decrease in the income statement of £58m and a 10% decrease in unbilled revenue would have the equal but opposite effect.

US dollar exchange rate change of 10%		55	641	65	600


1.	The effect of a 10% change in fair value assumes no hedge accounting.
2.	The changes shown are a change in the annual pension or other post-retirement benefit costs and change in the defined benefits obligations.
3.	A change in the discount rate is likely to occur as a result of changes in bond yields and as such would be expected to be offset to a significant degree by a change in the value of the bond assets held by the plans.
4.	The projected impact resulting from a change in RPI reflects the underlying effect on pensions in payment, pensions in deferment and resultant increases in salary assumptions.
5.	This change has been applied to both the pre 1 April 2013 and post 1 April 2013 rate of increase in salary assumption.
6.	Represents potential impact on fair values of commodity contracts only.
7.	The impact on net assets does not reflect the exchange translation in our US subsidiary net assets. It is estimated this would change by £781m (2013: £712m) in the opposite direction if the dollar exchange rate changed by 10%.
8.	Excludes sensitivities to LPI index. Further details on sensitivities are provided in note 30 (g) on page 143.

With the adoption of IAS 19 (revised), we have reviewed the pension assumptions that we consider key (as shown on page 136), and as a result have changed the sensitivities presented in the table above.

		33. Sensitivities on areas of estimation and uncertainty continued Pensions and other post-retirement benefits assumptions Sensitivities have been prepared to show how the DB obligations and annual service costs could potentially be impacted by changes in the relevant actuarial assumptions that were reasonably possible as at 31 March 2014. In preparing sensitivities the potential impact has been calculated by applying the change to each assumption in isolation and assuming all other assumptions remain unchanged. This is with the exception of RPI in the UK where the corresponding effect on pensions in payment, pensions in deferment and resultant increases in salary are recognised. Following the adoption of IAS 19 (revised) the pension sensitivities have been reviewed. The rate of change has been amended in respect of the impact of discount rate, and life expectancy is now shown as at age 65 (as opposed to age 60). A new sensitivity has been introduced for the impact of UK RPI. The impacts of salaries and US healthcare trend rates remain unchanged. Comparatives for each sensitivity have been presented on a consistent basis. The introduction of a new assumption in the UK for increases in salary for service from 1 April 2013 is reflected in the sensitivity analysis. Financial instruments assumptions Our financial instruments are sensitive to changes in market variables, being UK and US interest rates, the UK RPI and the dollar to sterling exchange rate. The changes in market variables affect the valuation of our borrowings, deposits, derivative financial instruments and commodity contracts. The analysis illustrates the sensitivity of our financial instruments to the changes in market variables. The following main assumptions were made in calculating the sensitivity analysis:
		—		the amount of net debt, the ratio of fixed to floating interest rates of the debt and derivatives portfolio, and the proportion of financial instruments in foreign currencies are all constant and on the basis of the hedge designations in place at 31 March 2014 and 2013 respectively;
		—		the statement of financial position sensitivity to interest rates relates only to derivative financial instruments and available-for-sale investments, as debt and other deposits are carried at amortised cost and so their carrying value does not change as interest rates move;
		—		the sensitivity of accrued interest to movements in interest rates is calculated on net floating-rate exposures on debt, deposits and derivative instruments;
		—		changes in the carrying value of derivatives from movements in interest rates of designated cash flow hedges are assumed to be recorded fully within equity; and
		—		changes in the carrying value of derivative financial instruments designated as net investment hedges from movements in interest rates are recorded in the income statement as they are designated using the spot rather than the forward translation method. The impact of movements in the dollar to sterling exchange rate are recorded directly in equity.
		34. Additional disclosures in respect of guaranteed securities
				We have three debt issuances (including preferred shares) that are listed on a US national securities exchange and are guaranteed by other companies in the Group. These guarantors commit to honour any liabilities should the company issuing the debt have any financial difficulties. In order to provide debt holders with information on the financial stability of the companies providing the guarantees, we are required to disclose individual financial information for these companies. We have chosen to include this information in the Group financial statements rather than submitting separate stand-alone financial statements.
		The following condensed consolidating financial information, comprising statements of comprehensive income, statements of financial position and cash flow statements, is given in respect of National Grid Gas plc (subsidiary guarantor), which became joint full and unconditional guarantor on 11 May 2004 with National Grid plc (parent guarantor) of the 6.625% Guaranteed Notes due 2018 issued in June 1998 by British Transco Finance Inc., then known as British Gas Finance Inc. (issuer of notes). Condensed consolidating financial information is also provided in respect of Niagara Mohawk Power Corporation as a result of National Grid plc’s guarantee, dated 29 October 2007, of Niagara Mohawk’s 3.6% and 3.9% issued preferred shares. National Grid Gas plc, British Transco Finance Inc., and Niagara Mohawk Power Corporation are wholly-owned subsidiaries of National Grid plc. The following financial information for National Grid plc, National Grid Gas plc, British Transco Finance Inc., and Niagara Mohawk Power Corporation on a condensed consolidating basis is intended to provide investors with meaningful and comparable financial information and is provided pursuant to various rules including Rule 3-10 of Regulation S-X in lieu of the separate financial statements of each subsidiary issuer of public debt securities. This financial information should be read in conjunction with the other disclosures in these financial statements.

Company accounting policies

We are required to include the stand-alone balance sheet of our ultimate parent Company, National Grid plc, under the Companies Act 2006. This is because the publicly traded shares are those of National Grid plc and the following disclosures provide additional information to shareholders.

D. Foreign currencies

Transactions in currencies other than the functional currency of the Company are recorded at the rates of exchange prevailing on the dates of the transactions. At each balance sheet date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at closing exchange rates. Gains and losses arising on retranslation of monetary assets and liabilities are included in the profit and loss account.

E. Financial instruments

The Company’s accounting policies under UK GAAP, namely FRS 25 ‘Financial Instruments: Presentation’, FRS 26 ‘Financial Instruments: Measurement’ and FRS 29 ‘Financial Instruments: Disclosures’, are the same as the Group’s accounting policies under IFRS, namely IAS 32 ‘Financial Instruments: Presentation’, IAS 39 ‘Financial Instruments: Recognition and Measurement’ and IFRS 7 ‘Financial Instruments: Disclosures’. The Company applies these policies only in respect of the financial instruments that it has, namely investments, derivative financial instruments, debtors, cash at bank and in hand, borrowings and creditors.

The policies are set out in notes 13, 15, 17, 18, 19 and 20 to the consolidated financial statements. The Company is taking the exemption for financial instruments disclosures, because IFRS 7 disclosures are given in notes 30 and 33 to the consolidated financial statements.

F. Hedge accounting

The Company applies the same accounting policy as the Group in respect of fair value hedges and cash flow hedges. This policy is set out in note 15 to the consolidated financial statements.

G. Parent Company guarantees

The Company has guaranteed the repayment of the principal sum, any associated premium and interest on specific loans due by certain subsidiary undertakings primarily to third parties. In the event of default or non performance by the subsidiary, the Company recognises such guarantees as insurance contracts, at fair value with a corresponding increase in the carrying value of the investment.

H. Share awards to employees of subsidiary undertakings

The issuance by the Company to employees of its subsidiaries of a grant over the Company’s options represents additional capital contributions by the Company to its subsidiaries. An additional investment in subsidiaries results in a corresponding increase in shareholders’ equity. The additional capital contribution is based on the fair value of the option at the date of grant, allocated over the underlying grant’s vesting period. Where payments are subsequently received from subsidiaries, these are accounted for as a return of a capital contribution and credited against the Company’s investments in subsidiaries. The Company has no employees.

I. Dividends

Interim dividends are recognised when they are paid to the Company’s shareholders. Final dividends are recognised when they are approved by shareholders.

A. Basis of preparation of individual financial statements under UK GAAP

These individual financial statements of the Company have been prepared in accordance with applicable UK accounting and financial reporting standards and the Companies Act 2006. They have been prepared on an historical cost basis, except for the revaluation of financial instruments, and are presented in pounds sterling, which is the currency of the primary economic environment in which the Company operates. The 2013 comparative financial information has also been prepared on this basis.

These individual financial statements have been prepared on a going concern basis following the assessment made by the Directors as set out on page 52.

The Company has not presented its own profit and loss account as permitted by section 408 of the Companies Act 2006.

The Company has taken advantage of the exemptions in FRS 8 ‘Related Party Disclosures’ from disclosing transactions with other members of the National Grid plc group of companies.

In accordance with exemptions under FRS 29 ‘Financial Instruments: Disclosures’, the Company has not presented the financial instruments disclosures required by the standard, as disclosures which comply with the standard are included in the consolidated financial statements.

B. Fixed asset investments

Investments held as fixed assets are stated at cost less any provisions for impairment. Investments are reviewed for impairment if events or changes in circumstances indicate that the carrying amount may not be recoverable. Impairments are calculated such that the carrying value of the fixed asset investment is the lower of its cost or recoverable amount. Recoverable amount is the higher of its net realisable value and its value-in-use.

C. Taxation

Current tax for the current and prior periods is provided at the amount expected to be paid or recovered using the tax rates and tax laws that have been enacted or substantively enacted by the balance sheet date.

Deferred tax is provided in full on timing differences which result in an obligation at the balance sheet date to pay more tax, or the right to pay less tax, at a future date, at tax rates expected to apply when the timing differences reverse based on tax rates and tax laws that have been enacted or substantively enacted by the balance sheet date. Timing differences arise from the inclusion of items of income and expenditure in taxation computations in periods different from those in which they are included in the financial statements.

Deferred tax assets are recognised to the extent that it is regarded as more likely than not that they will be recovered. Deferred tax assets and liabilities are not discounted.

Additional Information			Business information in detail
Additional Information			UK regulation Our licences, established under the Gas Act 1986 and Electricity Act 1989, as amended (the Acts), require us to develop, maintain and operate economic and efficient networks and to facilitate competition in the supply of gas and electricity in Great Britain. They also give us statutory powers, such as the right to bury our pipes or cables under public highways and the ability to use compulsory powers to purchase land to enable the conduct of our business. Our networks are regulated by Ofgem, which has established price control mechanisms that set the amount of revenue that can be earned by our regulated businesses. Price control regulation is designed to ensure our interests, as a monopoly, are balanced with those of our customers. Ofgem allows us to charge reasonable, but not excessive, prices giving us a future level of revenue sufficient to meet our statutory duties and licence obligations, and also to make a reasonable return on our investment. The price control includes a number of mechanisms to achieve its objectives, including financial incentives designed to encourage us to: continuously improve the cost and effectiveness of our services; manage and operate our networks efficiently; deliver high-quality services to our customers and wider stakeholder community; and invest in the development of the network in a manner that ensures long-term security of supply. Our UK Electricity Transmission (UK ET), UK Gas Transmission (UK GT) and UK Gas Distribution (UK GD) businesses operate under eight separate price controls in the UK. These comprise two for our UK ET operations, one covering our role as transmission owner (TO) and the other for our role as system operator (SO); two for our UK GT operations, again one as TO and one as SO; and one for each of our four regional gas distribution networks. While each of the eight price controls may have differing terms, they are based on a consistent regulatory framework. In addition to the eight price controls, our LNG storage business has a price control covering some aspects of its operations. There is also a tariff cap price control applied to certain elements of domestic metering and daily meter reading activities undertaken by National Grid Metering. Interconnectors derive their revenues from congestion revenues. Congestion revenues are dependent on the existence of price differentials between markets at either end of the interconnector. European legislation governs how capacity is allocated. It requires all interconnection capacity to be allocated to the market via market-based methods, ie auctions. There are two routes for interconnector investment: a regulated route, where interconnector developers have to comply with all aspects of European legislation on cross-border electricity infrastructure and receive a regulated return for their investment; or a merchant-exempt route, where developers would face the full upside and downside of the investment and typically have an exemption from European legislation. National Grid’s UK interconnectors earn their revenue by auctioning capacity based on the price difference between the markets at each end of the link and are referred to as merchant interconnectors; this being the typical UK model.

RIIO price controls Our UK regulator has introduced a new regulatory framework called RIIO (revenue = incentives + innovation + outputs) that became effective on 1 April 2013 and lasts for eight years. The building blocks of the RIIO price control are broadly similar to the historical price controls used in the UK; however there are some significant differences in the mechanics of the calculations. How is revenue calculated? Under RIIO the outputs we deliver are clearly articulated and are integrally linked to the calculation of our allowed revenue. These outputs have been determined through an extensive consultation process which has given stakeholders a greater opportunity to input to these decisions. The clarity around outputs should lead to greater transparency of our performance in delivering them. The six key output categories are: · Safety: ensuring the provision of a safe energy network. · Reliability (and availability): promoting networks capable of delivering long-term reliability, as well as minimising the number and duration of interruptions experienced over the price control period, and ensuring adaptation to climate change. · Environmental impact: encouraging companies to play their role in achieving broader environmental objectives – specifically facilitating the reduction of carbon emissions – as well as minimising their own carbon footprint. · Customer and stakeholder satisfaction: maintaining high levels of customer satisfaction and stakeholder engagement, and improving service levels. · Customer connections: encouraging networks to connect customers quickly and efficiently. · Social obligations (UK GD only): extending the gas network to communities that are fuel poor where it is efficient to do so and introducing measures to address carbon monoxide poisoning incidents. Within each of these output categories are a number of primary and secondary deliverables, reflecting what our stakeholders want us to deliver over the coming price control period. The nature and number of these deliverables varies according to the output category, with some being linked directly to our allowed revenue, some linked to legislation, and others having only a reputational impact. Ofgem, using information submitted by us along with independent assessments, determines the efficient level of expected costs necessary to deliver them. Under RIIO this is known as totex, short for total expenditure, and is similar to the sum of controllable opex, capex and repex (for UK GD) under the previous price control. A number of assumptions are necessary in setting these outputs, such as certain prices or the volumes of work that will be needed. As a result, to protect us and our customers from windfall gains and losses, there are a number of uncertainty mechanisms within the RIIO framework that can result in adjustments to totex if actual prices or volumes differ from the assumptions. Where we under- or over-spend the allowed totex for reasons that are not covered by uncertainty mechanisms, there is a sharing factor, ie the under- or over-spend is shared between us and customers through an adjustment to allowed revenues in a future year. This sharing factor provides an incentive for us to provide the outputs efficiently as we are able to keep a portion of the savings, with the remainder benefiting our customers.	This sharing factor is one of the ways that RIIO has given innovation more prominence. Innovation includes traditional areas such as new technologies, as well as the broader challenge of finding new ways of working to deliver outputs more efficiently. This broader challenge will have an impact on everyone in our business. Totex is then split between fast and slow money, a new concept under RIIO, based on a specified percentage. Fast money represents the amount of totex that we are able to recover in the current year. Slow money is added to our RAV. In addition to fast money, in each year we are allowed to collect a depreciation of and a return on our RAV. This operates in a similar way to the previous price control, although there have been changes to the asset lives for electricity transmission (transition from 20 years to 45 years evenly across the RIIO period) and the depreciation calculation for UK GD (changed from 45 years straight line to 45 years sum of digits for assets added post 2002). We are also allowed to collect additional revenues related to non-controllable costs and incentives. The incentive mechanisms can increase or decrease our allowed revenue and result from our performance against various measures related to our outputs. RIIO has introduced new incentive mechanisms as a way to provide further incentives to align our objectives with those of our customers and other stakeholders. For example, performance against our customer satisfaction targets can have a positive or negative effect of up to 1% of allowed annual revenues. Incentives will normally affect our revenues two years after the year of performance. RIIO regulatory building blocks Allowed returns The cost of capital allowed under RIIO is as follows:
		Transmission			Gas Distribution
		Gas	Electricity
	Cost of equity (post-tax real)	6.8%		7.0%	6.7%
	Cost of debt (pre-tax real)	iBoxx 10 year simple trailing average index (2.92% for 2013/14)
	Notional gearing	62.5%		60.0%	65.0%
	Vanilla WACC¹	4.38%		4.55%	4.24%
	1. Vanilla WACC = cost of debt x gearing + cost of equity x (1- gearing).

US regulation

Regulators

In the US, public utilities’ retail transactions are regulated by state utility commissions, including the NYPSC, the MADPU and the RIPUC.

Utility commissions serve as economic regulators, approving cost recovery and authorised rates of return. The state commissions establish the retail rates to recover the cost of transmission and distribution services, and focus on services and costs within their jurisdictions. FERC regulates the wholesale transactions of public utilities, such as interstate transmission and electricity generation, and provides for the wholesale cost recovery of these services.

Utility commissions are also charged with serving the public interest by ensuring utilities provide safe and reliable service at just and reasonable prices. They establish service standards and approve mergers and acquisitions of public utilities. FERC also regulates public utility holding companies and centralised service companies, including those of our US businesses.

With the exception of residential gas customers in Rhode Island, all of our customers are allowed to select a competitive supplier for the supply component of electricity and gas utility services.

Regulatory process

Utilities in the US submit a formal rate filing to the relevant state regulatory body, requesting a revenue adjustment in a proceeding known as a rate case.

The rate case process is conducted in a litigated setting and, in the states in which we operate, it can take 10 to 13 months for the commission to render a final decision. In all states, the utility is required to prove that its requested rate change is prudent and reasonable. The utility may request a rate plan that can span multiple years. Unlike the state processes, the federal regulator has no specified timeline for adjudicating a rate case, but typically makes a final decision retroactive when the case is completed.

During the rate case process, consumer advocates and other intervening parties scrutinise and often file opposing positions to the utility’s rate request. The rate case decision reflects a weighing of the facts in light of the regulator’s policy objectives.

During a rate case, the utility, consumer advocates and intervening parties may agree on the resolution of aspects of a case and file a negotiated settlement with a commission for approval.

Gas and electricity rates are established from a revenue requirement which comprises the utility’s total cost of providing distribution or delivery service to its customers. It includes operating expenses, depreciation, taxes and a fair and reasonable return on certain components of the utility’s regulated asset base, typically referred to as its rate base.

The rate of return applied to the rate base is the utility’s weighted average cost of capital. This represents its cost of debt and an allowed RoE intended to provide the utility with an opportunity to attract capital from investors and maintain its financial integrity. The total revenue requirement is apportioned among different customer classes and categories of service to establish the prices for service. The final revenue requirement and prices are ultimately approved in the rate case decision.

The revenue requirement is derived from a comprehensive study of the utility’s total costs during a recent 12 month period of operations, referred to as a test year.

Each commission has its own rules and standards for adjustments to the test year. These are intended to arrive at the total costs expected in the first year new rates will be in effect, or the rate year, and may include forecast capital investments in determining rate year rate base. Often, known and measurable adjustments are made to test year data to reflect normal operating conditions. In Massachusetts, only limited adjustments to this test year are allowed, which are required to be both known and measurable. New York and Rhode Island allow more comprehensive adjustments to the test year. In summary, the US regulatory regime is based on a building block approach intended to allow the utility to recover its cost of service and earn a return on its investments.

networks (upstate New York, New York City, Long Island, Massachusetts (2), and Rhode Island). Distribution and transmission electricity services in upstate New York are recovered with a combined rate billed to end use customers. In New England, retail transmission rates recover wholesale transmission charges assessed to our electric distribution companies from our end use customers.

Our rate plans are designed to a specific allowed RoE, by reference to an allowed operating expense level and rate base. Some rate plans include earnings sharing mechanisms that allow us to retain a proportion of the earnings above our allowed RoE we achieve through improving efficiency, with the balance benefiting customers.

In addition, our performance under certain rate plans is subject to service performance targets. We may be subject to monetary penalties in cases where we do not meet those targets.

Allowed RoE in context

One measure used to monitor the performance of our regulated businesses is a comparison of achieved RoE to allowed RoE, with a target that the achieved should be equal to or above the allowed. This measure cannot be used in isolation, however, as there are a number of factors that may prevent us from achieving that target in any given year:

· Regulatory lag: in the years following the rate year, costs may increase due to inflation or other factors. If the cost increases cannot be offset by productivity gains, the total cost to deliver will be higher as a proportion of revenue and therefore achieved RoE will be lowered.

· Cost disallowances: a cost disallowance is a decision by the regulator that a certain expense should not be recovered in rates from customers. The regulator may do this for a variety of reasons. We can respond to some disallowances by choosing not to incur those costs; others may be unavoidable. As a result, unless offsetting cost reductions can be found, the achieved RoE will be lowered.

· Market conditions: if a utility files a new rate case, the new allowed RoE may be below the current allowed RoE as financial market conditions may have changed. As such, a utility that appears to be underperforming the allowed RoE and files a new rate case may not succeed in increasing revenues.

We work to increase achieved RoEs through: productivity improvements; positive performance against incentives or earned savings mechanisms such as energy efficiency programmes, where available; and, through filing a new rate case when achieved returns are lower than that which the Company could reasonably expect to attain through a new rate case.

Features of our rate plans

We are responsible for billing our customers for their use of electricity and gas services. Customer bills typically comprise a commodity charge, covering the cost of the electricity or gas delivered, and charges covering our delivery service. Depending on the state, delivery rates are either based upon actual sales volumes and costs incurred in an historical test year, or on estimates of sales volumes and costs, and in both cases may differ from actual amounts. A substantial proportion of our costs, in particular electricity and gas purchases for supply to customers, are pass-through costs, meaning they are fully recoverable from our customers. These pass-through costs are recovered through separate charges to customers that are designed to recover those costs with no profit. Rates are adjusted from time to time to ensure any over- or under-recovery of these costs is returned to,

or recovered from, our customers. There can be timing differences between costs being incurred and rates being adjusted.

Revenue for our wholesale transmission businesses in New England and New York is collected from wholesale transmission customers, who are typically other utilities and include our own New England electricity distribution businesses. With the exception of upstate New York, which continues to combine retail transmission and distribution rates to end use customers, these wholesale transmission costs are incurred by distribution utilities on behalf of their customers and are fully recovered as a pass-through from end use customers as approved by each state commission. Our Long Island generation plants sell capacity to LIPA under a power supply agreement, approved by FERC, which provides a similar economic effect to cost of service rate regulation.

US regulatory filings

The objectives of our rate case filings are to ensure we have the right cost of service with the ability to earn a fair and reasonable rate of return, while providing a safe and reliable service to our customers. In order to achieve these objectives and to reduce regulatory lag, we have been requesting structural changes, such as revenue decoupling mechanisms, capital trackers, commodity-related bad debt true-ups, and pension and other post-employment benefit (OPEB) true-ups, separately from base rates. These terms are explained below the table on page 165.

Below we summarise significant developments in rate filings and the regulatory environment during the year.

Massachusetts

Capital investment programmes

Our Massachusetts gas and electricity operating companies have rate mechanisms that allow for the recovery of new capital investment, including a return, outside of base rate proceedings, subject to further review and reconciliation. Most recently, on the gas side, MADPU allowed approximately $11.6 million into rates effective from 1 November 2013, related to incremental additions to the rate base, and on the electricity side it allowed approximately $8.8 million into rates effective from 1 March 2014, related to rate base additions.

Storm fund recovery

The Massachusetts electricity business collects $4.3 million per year in base rates to credit towards a storm fund devoted to funding storm restoration. The severity and frequency of storms in Massachusetts over the last few years left our storm fund in a deficit position of approximately $212 million. On 3 May 2013, MADPU allowed us to begin collecting $40 million per year for three years towards the replenishment of the storm fund, subject to a review of the prudency of the underlying costs. That review is under way. The funding of the remaining deficit will be addressed as part of the prudency review and in future rate proceedings.

Storm management audit

The MADPU’s December 2012 order regarding our performance during Tropical Storm Irene and the October 2011 snowstorm requires us to undergo an independent audit regarding our storm management. This audit is under way, addressing: emergency management systems, protocols and plans; preparation for and management of restoration efforts with respect to emergency events; the Company’s emergency response resources and allocation of those resources during an emergency event; communications with state, municipal and public safety officials and with the DPU; dissemination of timely information to the public; and identification of management recommendations.

New York

Upstate New York 2012 rate plan filing

Effective from 1 April 2013, the upstate New York electricity and gas businesses began the first year of their new three year rate plan. The new rate plan provides an increase in electricity delivery revenue of $43.4 million, $51.4 million and $28.3 million for rate years one to three respectively. For the gas operations, the rate plan provides a decrease in delivery revenue of $3.3 million in rate year one and an increase of $5.9 million and $6.3 million in rate years two and three respectively. The revenue requirements for Niagara Mohawk’s electricity and gas businesses are based on a RoE of 9.3%, which includes a stay out premium for the three year term, and a capital structure that includes a 48% common equity component. The final agreement also includes annual reconciliation mechanisms for certain non-controllable costs.

Downstate New York rate plan extension

In 2013, The Brooklyn Union Gas Company (also known as KeySpan Energy Delivery New York or KEDNY) received approval from the PSC to extend its existing five year rate plan by two years. The extension provides a 9.4% RoE, with a 48% equity structure. Under the agreement, 80% of any earnings over 9.4% will fund recovery of prior environmental deferrals with the remaining 20% being retained by KEDNY. The agreement increased capital expenditure allowances to $320.1 million in 2013 and $293.7 million in 2014 as compared with the prior capital allowances of $155.4 million per year. The agreement also proposed updates to various customer service and other performance metrics.

2013 New York gas management audit

On 13 February 2013, the PSC announced a comprehensive management and operations audit of National Grid’s three New York gas distribution utilities. New York law requires periodic management audits of all utilities at least once every five years. We last underwent a management audit in 2009 when the PSC audited Niagara Mohawk’s electricity business.

The final report is expected to be filed with the PSC this summer. The report will make recommendations regarding the operation and management of our New York gas utilities, and will specify costs and savings associated with each recommendation. In our next major gas rate proceeding, the Commission will consider our effectiveness in implementing the audit recommendations and seek to reflect the costs and savings associated with the recommendations in rates.

Long Island

LIPA Amended and Restated Power Supply Agreement (A&RPSA)

We own and manage a number of power plants on Long Island, with a generation capacity of 3.8 GW. We supply wholesale capacity and energy to LIPA under an agreement with LIPA that was renewed in May 2013. LIPA in turn provides retail electricity to communities and businesses on Long Island.

On 23 May 2013, FERC approved the A&RPSA which expires on 30 April 2028 and replaces the original Power Supply Agreement that was effective from May of 1998 to May of 2013. LIPA may terminate the agreement as early as 30 April 2025 upon two years’ advance notice. The A&RPSA became effective on 28 May 2013.

The agreement resulted in a rate decrease of $27.4 million annually compared with the rate in effect for the final year of the previous PSA. The agreement sets a RoE of 9.75% and a capital structure with an equity component of 50%. The A&RPSA continues certain annual rate adjustments, such as pension and other post-retirement benefit expenses, property tax true-up, adjustments for new plant in service, and certain inflationary

increases. The A&RPSA allows both parties a RoE reopener in contract years four to six depending on financial market changes, and National Grid a one-time rate reopener in contract year six.

The A&RPSA also contains new options for modernising the power plants through retirement or repowering existing facilities to reduce energy costs and improve environmental performance.

Rhode Island

Rhode Island 2014/15 electricity and gas infrastructure, safety, and reliability plans (ISR)

Legislation provides our Rhode Island gas and electricity operating divisions with rate mechanisms that allow for recovery of capital investment, including a return, outside of base rate proceedings through the submission of annual ISR plans.

The electricity plan includes electricity operation expenses for vegetation management and certain inspection and maintenance costs.

In December 2013, we filed annual petitions seeking approval of our 2014/15 ISR plans for the electricity and gas systems. The PUC approved the petitions in March 2014.

The electricity ISR plan encompasses a $74.3 million spending programme for capital investment and $10.7 million for operating and maintenance expenses for vegetation management and inspection and maintenance.

The gas ISR plan encompasses a $71.7 million spending for capital investment and, for the first time, incremental operation and maintenance expense for the hiring, training and supervision of additional personnel to support increases in leak-prone pipe replacement.

FERC

Complaint on transmission allowed RoE

In September 2011 and December 2012, complaints were filed with FERC against certain transmission owners, including our New England transmission business, to lower the base RoE from the FERC approved rate of 11.14% to 9.2% and 8.7% respectively. The transmission owners argued that the complainants have not proven the existing rate is unjust and unreasonable and that the 11.14% base RoE should remain in effect. Non-binding preliminary findings by a FERC administrative law judge, suggested a 10.6% base RoE for a 15 month refund and a 9.7% base RoE prospectively.

Short-term borrowing extension

In October 2013, National Grid filed an application with FERC on behalf of its electricity public utility subsidiaries seeking an extension of the Commission’s prior authorisation to issue short-term debt, as required by Section 204 of the Federal Power Act. National Grid explained in its extension request that challenges associated with the implementation of the US enterprise resource system had delayed the production of certain FERC financial reports that are required in any Section 204 filing. FERC denied the extension request on the grounds that the lack of current FERC financial reports rendered the Commission unable to make the required findings under Section 204 as to the Company’s ability to perform certain public utility functions. As a result, National Grid implemented a contingency plan aimed at ensuring that each impacted public utility subsidiary would have sufficient cash resources pending a new short-term borrowing authorisation. This contingency plan included the receipt of open account advances and/or capital contributions permitted under the existing FERC borrowing authorisation. National Grid intends to file its Section 204 renewal applications as soon as practicable this year.

^†Revenue decoupling

A mechanism that removes the link between a utility’s revenue and sales volume so that the utility is indifferent to changes in usage. Revenues are reconciled to a revenue target, with differences billed or credited to customers. Allows the utility to support energy efficiency.

^‡Capital tracker

A mechanism that allows for the recovery of the revenue requirement of incremental capital investment above that embedded in base rates, including depreciation, property taxes and a return on the incremental investment.

^§Commodity-related bad debt true-up

A mechanism that allows a utility to reconcile commodity-related bad debt to either actual commodity-related bad debt or to a specified commodity-related bad debt write-off percentage. For electricity utilities, this mechanism also includes working capital.

¯Pension/OPEB true-up

A mechanism that reconciles the actual non-capitalised costs of pension and OPEB and the actual amount recovered in base rates. The difference may be amortised and recovered over a period or deferred for a future rate case.

				Risk factors
				Management of our risks is an important part of our internal control environment, as we describe on pages 22 to 25. In addition to the principal risks listed we face a number of inherent risks that could have a material adverse effect on our business, financial condition, results of operations and reputation, as well as the value and liquidity of our securities. Any investment decision regarding our securities and any forward-looking statements made by us should be considered in the light of these risk factors and the cautionary statement set out on the inside back cover. An overview of the key inherent risks we face is provided below.
				Risk factors
				Potentially harmful activities
				Aspects of the work we do could potentially harm employees, contractors, members of the public or the environment. Potentially hazardous activities that arise in connection with our business include the operation and maintenance of electricity generation facilities, electricity lines and substations and the storage, transmission and distribution of gas. Electricity and gas utilities also typically use and generate hazardous and potentially hazardous products and by-products. In addition, there may be other aspects of our operations that are not currently regarded or proved to have adverse effects but could become so, such as the effects of electric and magnetic fields. A significant safety or environmental incident, or the failure of our safety processes or of our occupational health plans, as well as the breach of our regulatory or contractual obligations or our climate change targets, could materially adversely affect our results of operations and our reputation. We commit significant resources and expenditure to process safety and to monitoring safety and occupational health, as well as environmental risks, and to meeting our obligations under negotiated settlements.		We are also subject to laws and regulations in the UK and US governing health and safety matters to protect the public and our employees and contractors, who could potentially be harmed by these activities as well as laws and regulations relating to pollution, the protection of the environment, and the use and disposal of hazardous substances and waste materials. These expose us to costs and liabilities relating to our operations and properties whether current, including those inherited from predecessor bodies, or formerly owned by us, and sites used for the disposal of our waste. The cost of future environmental remediation obligations is often inherently difficult to estimate and uncertainties can include the extent of contamination, the appropriate corrective actions and our share of the liability. We are increasingly subject to regulation in relation to climate change and are affected by requirements to reduce our own carbon emissions as well as reduction in energy use by our customers. If more onerous requirements are imposed or our ability to recover these costs under regulatory frameworks changes, this could have a material adverse impact on our business, reputation, results of operations and financial position. For more information about environmental, climate change and health and safety matters relating to our business, see the corporate responsibility section of our website.
				Infrastructure and IT systems
				We may suffer a major network failure or interruption, or may not be able to carry out critical non-network operations due to the failure of technology supporting our business-critical processes. Operational performance could be materially adversely affected by a failure to maintain the health of the system or network, inadequate forecasting of demand, inadequate record keeping or control of data or failure of information systems and supporting technology. This could cause us to fail to meet agreed standards of service, incentive and reliability targets, or be in breach of a licence, approval, regulatory requirement or contractual obligation. Even incidents that do not amount to a breach could result in adverse regulatory and financial consequences, as well as harming our reputation. In addition to these risks, we may be affected by other potential events that are largely outside our control, such as the impact of weather (including as a result of climate change and major storms), unlawful or unintentional acts of third parties, insufficient or unreliable supply or force majeure. Weather conditions can affect financial performance and severe weather that causes outages or damages infrastructure together with our actual or perceived response will materially adversely affect operational and potentially business performance and our reputation.		Malicious attack, sabotage or other intentional acts, including breaches of our cyber security, may also damage our assets (which include critical national infrastructure) or otherwise significantly affect corporate activities and, as a consequence, have a material adverse impact on our reputation, business, results of operations and financial condition. Unauthorised access to, or deliberate breaches of, our IT systems may also lead to manipulation of our proprietary business data or customer information. Unauthorised access to private customer information may make us liable for a violation of data privacy regulations. Even where we establish business continuity controls and security against threats against our systems, these may not be sufficient. Due to control weaknesses occurring from the implementation of the US business’s new enterprise resource system, associated controls over financial reporting and related system programme conversion difficulties, we may be unable to provide accurate financial reporting and regulatory compliance reporting in a timely manner, which may include the provision of financial statements. This could result in regulatory fines, penalties, and other sanctions and adversely impact our operations, our reputation and our relationship with our regulators and other stakeholders.

				Risk factors
				Law and regulation
				Changes in law or regulation or decisions by governmental bodies or regulators could materially adversely affect us. Most of our businesses are utilities or networks subject to regulation by governments and other authorities. Changes in law or regulation or regulatory policy and precedent, including decisions of governmental bodies or regulators, in the countries or states in which we operate could materially adversely affect us. If we fail to engage in the energy policy debate, we may not be able to influence future energy policy and deliver our strategy. Decisions or rulings concerning, for example: (i) whether licences, approvals or agreements to operate or supply are granted, amended or renewed, whether consents for construction projects are granted in a timely manner or whether there has been any breach of the terms of a licence, approval or regulatory requirement; and (ii) timely recovery of incurred expenditure or obligations, the ability to pass through commodity costs, a decoupling of				energy usage and revenue, and other decisions relating to the impact of general economic conditions on us, our markets and customers, implications of climate change, whether aspects of our activities are contestable, the level of permitted revenues and dividend distributions for our businesses and in relation to proposed business development activities, could have a material adverse impact on our results of operations, cash flows, the financial condition of our businesses and the ability to develop those businesses in the future. As the result of control weaknesses in our US business, we may be unable to provide timely regulatory reporting, which may include the provision of financial statements. This could result in the imposition of regulatory fines, penalties and other sanctions, which could impact our operations, our reputation and our relationship with our regulators and other stakeholders. For further information see pages 160 to 165, which explain our regulatory environment in detail.
				Business performance
				Current and future business performance may not meet our expectations or those of our regulators and shareholders. Earnings maintenance and growth from our regulated gas and electricity businesses will be affected by our ability to meet or exceed efficiency targets and service quality standards set by, or agreed with, our regulators.				If we do not meet these targets and standards, or if we do not implement the transformation projects we are carrying out as envisaged, including to our US financial systems and controls over financial reporting, or are not able to deliver our RIIO operating model and the US Elevate 2015 strategy successfully, we may not achieve the expected benefits, our business may be materially adversely affected and our performance, results of operations and reputation may be materially harmed and we may be in breach of regulatory or contractual obligations.
				Growth and business development activity
				Failure to respond to external market developments and execute our strategic ambition may negatively affect our performance. Conversely, new businesses or activities that we undertake alone or with partners may not deliver target outcomes and may expose us to additional operational and financial risk. Failure to grow our core business sufficiently and have viable options for new future business over the longer term could negatively affect the Group’s credibility and reputation and jeopardise the achievement of intended financial returns. Business development activities and the delivery of our growth ambition, including acquisitions, disposals, joint ventures, partnering and organic investment opportunities (including organic investments made as a result of changes to the energy				mix), are subject to a wide range of both external uncertainties (including the availability of potential investment targets and attractive financing), and internal uncertainties (including actual performance of our various existing operating companies and our business planning model assumptions and ability to integrate acquired businesses effectively). As a result, we may suffer unanticipated costs and liabilities and other unanticipated effects. We may also be liable for the past acts, omissions or liabilities of companies or businesses we have acquired, which may be unforeseen or greater than anticipated. In the case of joint ventures, we may have limited control over operations and our joint venture partners may have interests that diverge from our own. The occurrence of any of these events could have a material adverse impact on our results of operations or financial condition, and could also impact our ability to enter into other transactions.
				Cost escalation
				Changes in foreign currency rates, interest rates or commodity prices could materially impact earnings or our financial condition. We have significant operations in the US and so are subject to the exchange rate risks normally associated with non UK operations, including the need to translate US assets and liabilities, and income and expenses, into sterling, our primary reporting currency. In addition, our results of operations and net debt position may be affected because a significant proportion of our borrowings,				derivative financial instruments and commodity contracts are affected by changes in interest rates, commodity price indices and exchange rates, in particular the dollar to sterling exchange rate. Furthermore, our cash flow may be materially affected as a result of settling hedging arrangements entered into to manage our exchange rate, interest rate and commodity price exposure, or by cash collateral movements relating to derivative market values, which also depend on the sterling exchange rate into euro and other currencies.

		Risk factors
		Operating costs may increase faster than revenues.		In periods of inflation in the US, our operating costs may increase by more than our revenues. In both the UK and US such increased costs may materially adversely affect the results of our operations.
		Income under our price controls in the UK is linked to the RPI. Our operating costs may increase without a corresponding increase in the RPI and therefore without a corresponding increase in UK revenues. Our income under our rate plans in the US is not typically linked to inflation.

		We may be required to make significant contributions to fund pension and other post-retirement benefits. We participate in a number of pension schemes that together cover substantially all our employees. In both the UK and US, the principal schemes are DB schemes where the scheme assets are held independently of our own financial resources. In the US, we also have other post-retirement benefit schemes. Estimates of the amount and timing of future funding for the UK and US schemes are based on actuarial assumptions		and other factors including: the actual and projected market performance of the scheme assets, future long-term bond yields, average life expectancies and relevant legal requirements. Actual performance of scheme assets may be affected by volatility in debt and equity markets. Changes in these assumptions or other factors may require us to make additional contributions to these pension schemes which, to the extent they are not recoverable under our price controls or state rate plans, could materially adversely affect the results of our operations and financial condition.

		Financing and liquidity

		An inability to access capital markets at commercially acceptable interest rates could affect how we maintain and grow our businesses. Our businesses are financed through cash generated from our ongoing operations, bank lending facilities and the capital markets, particularly the long-term debt capital markets. Some of the debt we issue is rated by credit rating agencies and changes to these ratings may affect both our borrowing capacity and borrowing costs. In addition, restrictions imposed by regulators may also limit how we service the financial requirements of our current businesses or the financing of newly acquired or developing businesses. Financial markets can be subject to periods of volatility and shortages of liquidity. If we were unable to access the capital markets or other sources of finance at competitive rates for a prolonged period, our cost of financing may increase, the discretionary and uncommitted elements of our proposed capital investment programme may need to be reconsidered and the manner in which we implement our strategy may need to be reassessed. Such events could have a material adverse impact on our business, results of operations and prospects. Some of our regulatory agreements impose lower limits for the long-term senior unsecured debt credit ratings that certain		companies within the Group must hold or the amount of equity within their capital structures. One of the principal limits requires National Grid plc to hold an investment grade long-term senior unsecured debt credit rating. In addition, some of our regulatory arrangements impose restrictions on the way we can operate. These include regulatory requirements for us to maintain adequate financial resources within certain parts of our operating businesses and may restrict the ability of National Grid plc and some of our subsidiaries to engage in certain transactions, including paying dividends, lending cash and levying charges. The inability to meet such requirements or the occurrence of any such restrictions may have a material adverse impact on our business and financial condition. Due to control weaknesses in our US business, we may be unable to provide accurate financial information to our debt investors in a timely manner. Our debt agreements and banking facilities contain covenants, including those relating to the periodic and timely provision of financial information by the issuing entity and financial covenants, such as restrictions on the level of subsidiary indebtedness. Failure to comply with these covenants, or to obtain waivers of those requirements, could in some cases trigger a right, at the lender’s discretion, to require repayment of some of our debt and may restrict our ability to draw upon our facilities or access the capital markets.

		Customers and counterparties

		Customers and counterparties may not perform their obligations. Our operations are exposed to the risk that customers, suppliers, banks and other financial institutions and others with whom we do business will not satisfy their obligations, which could materially adversely affect our financial position.		This risk is significant where our subsidiaries have concentrations of receivables from gas and electricity utilities and their affiliates, as well as industrial customers and other purchasers, and may also arise where customers are unable to pay us as a result of increasing commodity prices or adverse economic conditions. There is also a risk to us where we invest excess cash, enter into derivatives and other financial contracts with banks or other financial institutions. Banks who provide us with credit facilities may also fail to perform under those contracts.

		Employees and others

		We may fail to attract, develop and retain employees with the competencies, including leadership and business capabilities, values and behaviours required to deliver our strategy and vision and ensure they are engaged to act in our best interests. Our ability to implement our strategy depends on the capabilities and performance of our employees and leadership at all levels of the business. Our ability to implement our strategy and vision may be negatively affected by the loss of key personnel or an inability to attract, integrate, engage and retain appropriately		qualified personnel, or if significant disputes arise with our employees. As a result, there may be a material adverse effect on our business, financial condition, results of operations and prospects. There is a risk that an employee or someone acting on our behalf may breach our internal controls or internal governance framework or may contravene applicable laws and regulations. This could have an impact on the results of our operations, our reputation and our relationship with our regulators and other stakeholders.

Internal control


		Information assurance				Internal control over financial reporting
		The Board considers that it is imperative to have accurate and reliable information to enable informed and timely decisions to be taken that further our objectives, and to ensure continued focus and quality of non-financial data that we supply to external third parties.				Our management, including the Chief Executive and Finance Director, has carried out an evaluation of our internal control over financial reporting pursuant to the Disclosure and Transparency Rules and Section 404 of the Sarbanes-Oxley Act 2002. As required by Section 404, management is responsible for establishing and maintaining an adequate system of internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Management evaluation of the effectiveness of the Company’s internal control over financial reporting was based on the Internal Control-Integrated Framework 1992 issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that our internal control over financial reporting was effective as at 31 March 2014. PricewaterhouseCoopers LLP, which has audited our consolidated financial statements for the year ended 31 March 2014, has also audited the effectiveness of our internal control over financial reporting. Their attestation report can be found on page 81. During the year, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, it.
		Key elements in managing information assurance risks include education, training, awareness and ongoing transformation initiatives.
		In line with ongoing transformation initiatives, we also continue to monitor and evolve our control processes, which is supported by the Certificate of Assurance process in which managers affirm, among other things, they have control frameworks in place to assist in the accurate reporting of data and other information. These initiatives emphasise the importance of information security, the quality of data collection and the affirmation process that supports our business transactions, evidencing our decisions and actions.
		All communication channels, including training for ‘Doing the Right Thing’, make it clear that the accurate and honest reporting of data and other information must never be compromised.
		Disclosure controls
		Working with management, including the Chief Executive and Finance Director, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures as at 31 March 2014. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives, however the effectiveness of any system of disclosure controls and procedures has limitations including the possibility of human error and the circumvention or overriding of the controls and procedures. Even effective disclosure controls and procedures provide only reasonable assurance of achieving their objectives. Based on the evaluation, the Chief Executive and Finance Director concluded that the disclosure controls and procedures are effective to provide reasonable assurance that information required to be disclosed in the reports that we file and submit under the Exchange Act is recorded, processed, summarised and reported as and when required and that such information is accumulated and communicated to our management, including the Chief Executive and Finance Director, as appropriate, to allow timely decisions regarding disclosure.

As at 31 March 2014, the Company had undrawn borrowing facilities with a number of its banks of £1.7 billion available to it and a further £1.1 billion of drawn bank loans which, on a change of control of the Company following a takeover bid, may alter or terminate. All the Company’s share plans contain provisions relating to a change of control. Outstanding awards and options would normally vest and become exercisable on a change of control, subject to the satisfaction of any performance conditions at that time. In the event of a change of control of the Company, a number of governmental and regulatory consents or approvals are likely to be required arising from laws or regulations of the UK, US or the EU. No other agreements that take effect, alter or terminate upon a change of control of the Company following a takeover bid are considered to be significant in terms of their potential impact on the business as a whole. Conflicts of interest The Board continues to monitor and note possible conflicts of interest that each Director may have and Directors are reminded of their continuing obligations in relation to conflicts at each Board meeting. Potential conflicts are considered and, if appropriate, approved and noted. During the year ended 31 March 2014, the Board has been advised by the Directors of a number of situations in relation to which no actual conflict of interest was identified and has therefore authorised such situations in accordance with its powers as set out in the Articles. Directors’ indemnity The Company has arranged, in accordance with the Companies Act 2006 and the Articles, qualifying third-party indemnities against financial exposure that Directors may incur in the course of their professional duties. Equivalent qualifying third-party indemnities were, and remain, in force for the benefit of those Directors who stood down from the Board during the year ended 31 March 2014. Alongside these indemnities, the Company places Directors’ and Officers’ liability insurance cover for each Director. Events after the reporting period There have been no material events affecting the Company since the year end.

Material interests in shares As at 31 March 2014, National Grid had been notified of the following holdings in voting rights of 3% or more in the issued share capital of the Company:			Share capital The share capital of the Company consists of ordinary shares of 11¹⁷⁄₄₃ pence nominal value each and ADSs, which represent five ordinary shares. Authority to purchase shares Shareholder approval was given at the 2013 AGM to purchase up to 10% of the Company’s share capital. The Directors intend to seek shareholder approval to renew this authority at this year’s AGM. In some circumstances, the Company may find it advantageous to have the authority to purchase its own shares in the market. The Directors believe that it is an important part of the financial management of the Company to have the flexibility to repurchase issued shares in order to manage its capital base. The Company will only purchase shares where the Directors believe this would be in the best interests of shareholders generally, for example to manage the excess share dilution created by a large take-up through the scrip dividend scheme. The authority will only be used after careful consideration, taking into account market conditions prevailing at the time, other investment opportunities, appropriate gearing levels and the overall financial position of the Company. Share issuance arising from the operation of the scrip dividend scheme may be actively managed through the repurchase of the Company’s shares. It is expected that such repurchases will not exceed 1% of the issued share capital (excluding treasury shares) per annum. For further details in relation to the management of the scrip dividend scheme, see page 02. Repurchased shares may be held as treasury shares by the Company, and resold for cash, cancelled, either immediately or at some point in the future, or used for the purposes of employee share schemes. No shares were repurchased during the year. Of the shares repurchased in prior years and held as treasury shares, 7,578,281 have been transferred to employees under the employee share plans, leaving a balance as at the date of this report of 119,565,599 ordinary shares held as treasury shares.

The Capital Group Companies, Inc.	414,173,676	11.103
Black Rock, Inc.	182,630,798	5.21
Crescent Holding GmbH	149,414,285	4.07

1. This number is calculated in relation to the issued share capital at the time the holding was disclosed. As at 18 May 2014, no further notifications have been received. The rights attached to ordinary shares are detailed on page 175. All ordinary shares carry the same voting rights. Political donations and expenditure National Grid made no donations in the UK or EU during the year, including donations as defined for the purposes of the Political Parties, Elections and Referendums Act 2000. National Grid USA and its affiliated New York and federal political action committees (each, a PAC) made political donations in the US totalling $100,325 (£61,929) during the year. National Grid USA’s affiliated New York PAC was funded partly by contributions from National Grid USA and certain of its subsidiaries and partly by voluntary employee contributions. National Grid USA’s affiliated federal PAC was funded wholly by voluntary employee contributions. Research and development Expenditure on research and development during the year was £12 million (2012/13: £15 million; 2011/12: £15 million). RIIO has strengthened the incentives and provided additional innovation funding support to stimulate innovation so that we deliver increased benefits for our stakeholders. During 2013/14, collaboration has been a key focus for a number of National Grid’s innovation projects in all three of our UK Regulated business areas: UK ET, UK GT and UK GD. Innovation in UK ET has focused on technologies and approaches for enhancing the capacity and the reliability of the electricity transmission network. UK GT has focused innovation on safety and alternative material while incorporating commercial, operation and process-led innovation to complement the preceding focus on asset management. Innovation in UK GD has centred around life extension and emission reduction, looking to robotic technologies that can remediate our assets while having the minimum of impact on our customers through street works. Focus has also been on understanding the potential of alternative fuel sources to support a low carbon economy.

		Authority to allot shares Shareholder approval was given at the 2013 AGM to allot shares of up to one third of the Company’s share capital and a further third in connection with an offer by way of a rights issue. This year the Directors are seeking a lower level of authority than in recent years, where an equivalent of two thirds of the issued share capital of the Company, exclusive of treasury shares, was sought. The Directors consider that the Company will have sufficient flexibility with the lower level of authority to respond to market developments. This authority is in line with investor guidelines. The Directors currently have no intention of issuing new shares, or of granting rights to subscribe for or convert any security into shares, except in relation to, or in connection with, the operation and management of the Company’s scrip dividend scheme and the exercise of options under the Company’s share plans. No issue of shares will be made which would effectively alter control of the Company without the sanction of shareholders in general meeting. The Company intends to actively manage the share issuance arising from the operation of the scrip dividend scheme. In some circumstances, additional shares may be allotted to the market under the authority provided by this resolution. Under these unlikely circumstances, it is expected that the allotment of new shares (or rights to subscribe for or convert any security into shares) will not exceed 1% of the issued share capital (excluding treasury shares) per annum. For further details in relation to the management of the scrip dividend scheme, see page 02. Rights attached to shares Ordinary shareholders and ADS holders receive dividends and can vote at general meetings. Treasury shares do not attract a vote or dividends. There are no restrictions on the transfer or sale of ordinary shares. Some of the Company’s employee share plans, details of which are contained in the Remuneration Report, include restrictions on the transfer of shares while the shares are subject to the plan. Where, under an employee share plan operated by the Company, participants are the beneficial owners of the shares but not the registered owner, the voting rights may be exercised by the registered owner at the direction of the participant.				Share price The following graph represents the movement of National Grid’s share price during 2013/14. A graph showing the total shareholder return over the last five years is available on page 72.

		General meetings AGMs must be convened each year within six months of the Company’s accounting reference date upon advance written notice of 21 clear days. Any other general meeting may be convened provided at least 14 clear days’ written notice is given, subject to annual approval of shareholders. In certain limited circumstances, the Company can convene a general meeting by shorter notice. The notice must specify, among other things, the nature of the business to be transacted, the place, the date and the time of the meeting. Rights of non residents There are no restrictions under National Grid’s Articles that would limit the rights of persons not resident in the UK to vote in relation to ordinary shares. Disclosure of interests Under the Companies Act 2006, National Grid may, by written notice, require a person whom it has reasonable cause to believe to be or to have been in the last three years interested in its shares to provide additional information relating to that interest. Under the Articles, failure to provide such information may result in a shareholder losing their rights to attend, vote or exercise any other right in relation to shareholders’ meetings. Under the UK Disclosure and Transparency Rules, there is also an obligation on a person who acquires or ceases to have a notifiable interest in shares in National Grid to notify the Company of that fact. The disclosure threshold is 3% and disclosure is required each time the person’s direct and indirect holdings reach, exceed or fall below each 1% threshold thereafter. The UK City Code on Takeovers and Mergers imposes strict disclosure requirements with regard to dealings in the securities of an offeror or offeree company, and also on their respective associates, during the course of an offer period. Other regulators in the UK, US and elsewhere may have, or assert, notification or approval rights over acquisitions or transfers of shares. Code of Ethics In accordance with US legal requirements, the Board has adopted a Code of Ethics for senior financial professionals. This code is available on our website (where any amendments or waivers will also be posted). There were no amendments to, or waivers of, our Code of Ethics during the year. Corporate governance practices: differences from New York Stock Exchange (NYSE) listing standards The Company is listed on the NYSE and is therefore required to disclose differences in its corporate governance practices adopted as a UK listed company, compared with those of a US company. The corporate governance practices of the Company are primarily based on the requirements of the UK Corporate Governance Code (the Code) but substantially conform to those required of US companies listed on the NYSE. The following is a summary of the significant ways in which the Company’s corporate governance practices differ from those followed by US companies under Section 303A Corporate Governance Standards of the NYSE.
		—		The NYSE rules and the Code apply different tests for the independence of board members.
		—		The NYSE rules require a separate nominating/corporate governance committee composed entirely of independent directors. There is, however, no requirement for a separate


				corporate governance committee in the UK. Under the Company’s corporate governance policies, all Directors on the Board discuss and decide upon governance issues and the Nominations Committee makes recommendations to the Board with regard to certain of the responsibilities of a corporate governance committee.
		—		The NYSE rules require listed companies to adopt and disclose corporate governance guidelines. While the Company reports compliance with the Code in each Annual Report and Accounts, the UK requirements do not require the Company to adopt and disclose separate corporate governance guidelines.
		—		The NYSE rules require a separate audit committee composed of at least three independent members. While the Company’s Audit Committee exceeds the NYSE’s minimum independent non-executive director membership requirements, it should be noted that the quorum for a meeting of the Audit Committee, of two independent non-executive directors, is less than the minimum membership requirements under the NYSE rules.
		—		The NYSE rules require a compensation committee composed entirely of independent directors, and prescribe criteria to evaluate the independence of the committee’s members and its ability to engage external compensation advisors. While the Code prescribes different independence criteria, the Non-executive Directors on the Remuneration Committee have each been deemed independent by the Board under the NYSE rules. Although the evaluation criteria for appointment of external advisors differ under the Code, the Remuneration Committee is solely responsible for appointment, retention and termination of such advisors.
		Depositary payments to the Company The Depositary has agreed to reimburse the Company for expenses it incurs that are related maintenance expenses of the ADS programme. The Depositary has also agreed to pay the standard out-of-pocket maintenance costs for the ADSs, which consist of the expenses of postage and envelopes for mailing annual and interim financial reports, printing and distributing dividend cheques, electronic filing of US federal tax information, mailing required tax forms, stationery, postage, facsimile and telephone calls. It has also agreed to reimburse the Company annually for certain investor relationship programmes or special investor relations promotional activities. There are limits on the amount of expenses for which the Depositary will reimburse the Company, but the amount of reimbursement available to the Company is not necessarily tied to the amount of fees the Depositary collects from investors. For the period 1 April 2013 to 16 May 2014, the Company received a total of $1,955,464 in reimbursements from the Depositary consisting of $1,215,766 and $739,698 received in September 2013 and March 2014 respectively. Fees that are charged on cash dividends will be apportioned between the Depositary and the Company, see page 178. Any questions from ADS holders should be directed to: The Bank of New York Mellon Depositary Receipts PO Box 30170 College Station, Texas 77842-3170 Telephone: 1-800-466-7215 (International +1-201-680-6825) Email: shrrelations@cpushareownerservices.com

Description of securities other than equity securities: depositary fees and charges

The Bank of New York Mellon, as Depositary, collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The Depositary collects fees for making distributions to investors (including, it is expected going forward, in respect of cash dividends) by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The Depositary may generally refuse to provide fee attracting services until its fees for those services are paid.

This discussion applies to holders who qualify for benefits under the income tax convention between the US and the UK (the Tax Convention) and are a resident of the US for the purposes of the Tax Convention and are not resident or ordinarily resident in the UK for UK tax purposes at any material time (a US Holder). US Holders generally will be entitled to benefits under the Tax Convention if they are: • the beneficial owner of the ADSs or ordinary shares, as applicable, and of any dividends that they receive; • an individual resident or citizen of the US, a US corporation, or a US partnership, estate, or trust (but only to the extent the income of the partnership, estate, or trust is subject to US taxation in the hands of a US resident person); and • not also a resident of the UK for UK tax purposes. If a US Holder holds ADSs or ordinary shares in connection with the conduct of business or the performance of personal services in the UK or otherwise in connection with a branch, agency or permanent establishment in the UK, then the US Holder will not be entitled to benefits under the Tax Convention. Special rules, including a limitation of benefits provision, apply in limited circumstances to ADSs or ordinary shares owned by an investment or holding company. This section does not discuss the treatment of holders described in the preceding two sentences. This section does not purport to be a comprehensive description of all the tax considerations that may be relevant to any particular investor. National Grid has assumed that shareholders, including US Holders, are familiar with the tax rules applicable to investments in securities generally and with any special rules to which they may be subject. In particular, the discussion deals only with investors that will beneficially hold ADSs or ordinary shares as capital assets and does not address the tax treatment of investors that are subject to special rules, such as banks, insurance companies, dealers in securities or currencies, partnerships or other entities classified as partnerships for US federal income tax purposes, persons that control (directly or indirectly) 10% or more of our voting stock, persons that elect mark-to-market treatment, persons that hold ADSs or ordinary shares as a position in a straddle, conversion transaction, synthetic security, or other integrated financial transaction, persons who are liable for the alternative minimum tax, or the Medicare tax on net investment income, and persons whose functional currency is not the dollar.

2007	KeySpan Corporation acquired

2008	Ravenswood generation station sold

2010	Rights issue raised £3.2 billion

2012	New Hampshire electricity and gas distribution businesses sold

180 National Grid Annual Report and Accounts 2013/14

Other disclosures

continued

The statements regarding US and UK tax laws and administrative practices set forth below are based on laws, treaties, judicial decisions and regulatory interpretations in effect on the date of this document. These laws and practices are subject to change without notice, possibly with retrospective effect. In addition, the US statements set forth below are based on the representations of The Bank of New York Mellon as depositary (the Depositary). These statements assume that each obligation provided for in, or otherwise contemplated by, the deposit agreement entered into between National Grid Transco plc (now National Grid plc), the Depositary and the registered holders of ADRs, pursuant to which ADSs have been issued, dated as of 21 November 1995 and amended and restated as of 1 August 2005, and any related agreement, will be performed in accordance with its terms. Beneficial owners of ADSs who are residents or citizens of the US will be treated as the owners of the underlying ordinary shares for the purposes of the US Internal Revenue Code.

For the purposes of the Tax Convention, the Estate Tax Convention and UK tax considerations, we have assumed that a holder of ADRs will be treated as the owner of the ordinary shares represented by those ADSs and this section is based on that assumption. Despite a ruling in 2012 by the First-Tier Tax Tribunal in the UK that has cast doubt on this view, HMRC has stated that it will continue to apply its long-standing practice of treating such an ADR holder as holding the beneficial interest in the underlying shares. As such, this is an area of some uncertainty that may be subject to further developments.

A US Holder should consult their own advisor as to the tax consequences of the purchase, ownership and disposition of ADSs or ordinary shares in light of their particular circumstances, including the effect of any state, local or other national laws.

Taxation of dividends

Under the Tax Convention, the UK is allowed to impose a 15% withholding tax on dividends paid to US shareholders controlling less than 10% of the voting capital of National Grid. The UK does not, however, currently impose a withholding tax on such dividends.

Cash distributions received by a US Holder with respect to their ADSs or ordinary shares generally will be treated as foreign source dividend income subject to US federal income taxation as ordinary income, to the extent paid out of National Grid’s current or accumulated earnings and profits, as determined under US federal income tax principles. The dollar amount of dividends received by certain non corporate US Holders with respect to ADSs or ordinary shares will generally be subject to taxation at the special reduced rate normally applicable to long-term capital gains, provided National Grid (i) is eligible for the benefits of the Tax Convention and (ii) was not, in the year prior to the year in which the dividend was paid, and is not, in the year in which the dividend is paid, a passive foreign investment company (PFIC).

Based on National Grid’s audited financial statements and relevant market and shareholder data, National Grid believes that it was not treated as a PFIC for US federal income tax purposes with respect to its taxable years ending 31 March 2013 and 2014. In addition, based on its current expectations regarding the value and nature of its assets, the sources and nature of its income, and relevant market and shareholder data, National Grid does not anticipate becoming a PFIC in the foreseeable future. Dividends paid by National Grid to corporate US Holders will not be eligible for the dividends received deduction generally allowed to corporations.

Taxation of capital gains

US Holders will not be liable for UK taxation on any capital gain realised on the disposal of ADSs or ordinary shares.

Sales or other taxable dispositions of ADSs or ordinary shares by a US Holder generally will give rise to US source capital gain or loss equal to the difference between the dollar value of the amount realised on the disposition and the US Holder’s dollar basis in the shares or ADSs. Any such capital gain or loss generally will be long-term capital gain or loss, currently subject to taxation at reduced rates for non corporate taxpayers, if the ordinary shares or ADSs were held for more than one year. The deductibility of capital losses is subject to limitations.

UK stamp duty and stamp duty reserve tax (SDRT)

Transfers of ordinary shares – SDRT at the rate of 0.5% of the amount of value of the consideration will generally be payable on any agreement to transfer ordinary shares that is not completed by the execution of a duly stamped instrument of transfer to the transferee. Where an instrument of transfer is executed and duly stamped before the expiry of the period of six years beginning with the date on which the agreement is made, the SDRT liability will be cancelled, and, if a claim is made within the specified period, any SDRT which has been paid will be refunded. SDRT is due whether or not the agreement or transfer of such chargeable securities is made or carried out in the UK and whether or not any party to that agreement or transfer is a UK resident. Purchases of ordinary shares completed by execution of a stock transfer form will generally give rise to a liability to UK stamp duty at the rate of 0.5% (rounded up to the nearest £5) of the amount or value of the consideration. Paperless transfers under the CREST paperless settlement system will generally be liable to SDRT at the rate of 0.5%, and not stamp duty. SDRT is generally the liability of the purchaser and UK stamp duty is usually paid by the purchaser or transferee.

Transfers of ADSs – No UK stamp duty will be payable on the acquisition or transfer of existing ADSs or beneficial ownership of ADSs, provided that any instrument of transfer or written agreement to transfer is executed outside the UK and remains at all times outside the UK. An agreement for the transfer of ADSs in the form of ADRs will not give rise to a liability for SDRT. A charge to stamp duty or SDRT may arise on the transfer of ordinary shares to the Depositary or The Bank of New York Mellon as agent of the Depositary (the Custodian). The rate of stamp duty or SDRT will generally be 1.5% of the value of the consideration or, in some circumstances, the value of the ordinary shares concerned. However, following a ruling in 2012 by the First-Tier Tax Tribunal in the UK, there is no 1.5% SDRT charge on the issue of ordinary shares (or, where it is integral to the raising of new capital, the transfer of ordinary shares) to the Depositary or the Custodian. The Depositary will generally be liable for the stamp duty or SDRT. In accordance with the terms of the Depositary Agreement, the Depositary will charge any tax payable by the Depositary or the Custodian (or their nominees) on the deposit of ordinary shares to the party to whom the ADSs are delivered against such deposits. If the stamp duty is not a multiple of £5, the duty will be rounded up to the nearest multiple of £5.

US information reporting and backup withholding tax Dividend payments made to US Holders and proceeds paid from the sale, exchange, redemption or disposal of ADSs or ordinary shares to US Holders may be subject to information reporting to the US Internal Revenue Service (IRS). Such payments may be subject to backup withholding taxes unless the holder (i) is a corporation or other exempt recipient or (ii) provides a taxpayer identification number on a properly completed IRS Form W-9 and certifies that no loss of exemption from backup withholding has occurred. US Holders should consult their tax advisors regarding these rules and any other reporting obligations that may apply to the ownership or disposition of ADSs or ordinary shares, including reporting requirements related to the holding of certain foreign financial assets. UK inheritance tax An individual who is domiciled in the US for the purposes of the Estate Tax Convention and who is not a national of the UK for the purposes of the Estate Tax Convention will generally not be subject to UK inheritance tax in respect of the ADSs or ordinary shares on the individual’s death or on a gift of the ADSs or ordinary shares during the individual’s lifetime, unless the ADSs or ordinary shares are part of the business property of a permanent establishment of the individual in the UK or pertain to a fixed base in the UK of an individual who performs independent personal services. Special rules apply to ADSs or ordinary shares held in trust. In the exceptional case where the ADSs or shares are subject both to UK inheritance tax and to US federal gift or estate tax, the Estate Tax Convention generally provides for the tax paid in the UK to be credited against tax paid in the US. The All-employee Share Plans The all-employee share plans allow UK- or US-based employees to participate in either HMRC (UK) or Internal Revenue Service (US) approved plans. We believe by offering participation in such plans, it encourages all employees (including Executive Directors) to become shareholders in National Grid. Sharesave Employees resident in the UK are eligible to participate in the Sharesave plan. Under this plan, participants may contribute between £5 and £250 in total each month, for a fixed period of three years, five years or both. Contributions are taken from net salary. SIP Employees resident in the UK are eligible to participate in the SIP. Contributions up to £125 are deducted from participants’ gross salary and used to purchase ordinary shares in National Grid each month. The shares are placed in trust. US Incentive Thrift Plans Employees of National Grid’s US companies are eligible to participate in the Thrift Plans, which are tax-advantaged savings plans (commonly referred to as 401(k) plans). They are DC pension plans that give participants the opportunity to invest up to applicable federal salary limits. The federal limits for calendar year 2013 are: for pre-tax contributions a maximum of 50% of salary limited to $17,500 for those under the age of 50 and $23,000 for those over 50; for post-tax contributions, up to 15% of salary. The total contributions (pre-tax and post-tax) are limited to the	lesser of 50% of compensation or $51,000. For calendar year 2014, participants may invest up to the applicable federal salary limits: for pre-tax contributions a maximum of 50% of salary limited to $17,500 for those under the age of 50 and $23,000 for those over 50; for post-tax contributions up to 15% of salary. The total contributions (pre-tax and post-tax) are limited to the lesser of 50% of compensation or $52,000. ESPP Employees of National Grid’s US companies are eligible to participate in the ESPP (commonly referred to as a 423(b) plan). Eligible employees have the opportunity to purchase ADSs on a monthly basis at a 15% discounted price. Under the plan employees may contribute up to 20% of base pay each year up to a maximum annual contribution of $18,888 to purchase ADSs in National Grid.

Reconciliations of adjusted profit measures

Use of adjusted profit measures

In considering the financial performance of our businesses and segments, we analyse each of our primary financial measures of operating profit, profit before tax, profit for the year attributable to equity shareholders and EPS into two components.

The first of these components is referred to as an adjusted profit measure, also known as a business performance measure. This is the principal measure used by management to assess the performance of the underlying business.

Adjusted results exclude exceptional items, remeasurements and stranded cost recoveries. These items are reported collectively as the second component of the financial measures. Note 4 on page 99 explains in detail the items which are excluded from our adjusted profit measures.

Adjusted profit measures have limitations in their usefulness compared with the comparable total profit measures as they exclude important elements of our financial performance. However, we believe that by presenting our financial performance in two components it is easier to read and interpret financial performance between periods, as adjusted profit measures are more comparable having removed the distorting effect of the excluded items. Those items are more clearly understood if separately identified and analysed.

The presentation of these two components of financial performance is additional to, and not a substitute for, the comparable total profit measures presented.

Management uses adjusted profit measures as the basis for monitoring financial performance and in communicating financial performance to investors in external presentations and announcements of financial results.

Internal financial reports, budgets and forecasts are primarily prepared on the basis of adjusted profit measures, although planned exceptional items, such as significant restructuring, are also reflected in budgets and forecasts. We separately monitor and disclose the excluded items as a component of our overall financial performance.

Analysis of the adjusted operating profit by segment for the year ended 31 March 2013

UK Electricity Transmission

Net regulated revenue increased by £235 million due to an increase in regulated revenues under UK price control allowances partly offset by a £10 million increase in charges under the balancing services incentive scheme. Timing increased by £67 million, with in year over-recovery of £29 million compared with a prior year under-recovery of £38 million.

Our controllable costs increased by £8 million driven by inflation, recruitment and training costs associated with our capital investment programme and increases in contribution rates for our DB pension schemes.

Depreciation and amortisation increased by £42 million as a result of higher asset values due to our capital investment programme.

UK Gas Transmission

Gas Transmission net regulated revenue increased by £112 million driven by increased price control revenues partly offset by lower incentive scheme performance and reduced auction revenues in our LNG storage business. There was no year-on-year timing movement due to an in year over-recovery of £17 million compared with a £17 million over-recovery in 2012/13.

Controllable costs increased by £21 million driven by inflation, an increase in our environmental provisions and increases in contribution rates for our DB pension schemes.

Depreciation and amortisation increased by £16 million due to an increase in the underlying asset base and some one-time asset write-offs.

UK Gas Distribution

Net regulated revenue increased by £85 million driven by our regulatory RPI-X pricing formula and improved performance under incentive programmes. Timing reduced adjusted operating profit by £32 million driven by in year under-recoveries of £10 million compared with an over-recovery in the prior year of £22 million. The estimated closing under-recovered value at 31 March 2013 was £8 million.

Regulated controllable costs increased by £13 million due to: inflation, system maintenance costs and one-off contract strategy costs, partially offset by efficiencies enabled by our new front office systems. Post-retirement costs increased by £2 million as a result of increased contribution rates for our DB pension schemes.

Depreciation and amortisation increased by £10 million driven by higher average asset values due to the capital investment programme and new front office systems. Finally, other costs decreased by £3 million, resulting in an adjusted operating profit of £794 million for the year.

US Regulated

Our US Regulated business was affected by a reduction in timing differences of £37 million due to in year under-recoveries of £20 million compared with a prior year over-recovery of £17 million (after adjusting for foreign exchange movements).

The estimated closing over-recovered value at 31 March 2013 was £110 million. This was offset by a year-on-year reduction in major storm costs of £33 million, as the financial impact of Superstorm Sandy and Storm Nemo was lower than that from Hurricane Irene and the Massachusetts October snowstorm in 2011/12.

Net costs incurred in the US after insurance proceeds were £33 million lower than 2011/12 (after adjusting for foreign exchange movements).

An increase of £135 million in net regulated income reflects deferral recoveries in our upstate New York businesses together with higher revenues from our capital tracker regulatory arrangements.

Regulated controllable operating costs increased by £19 million reflecting inflation and higher spend on IS outsourcing and security. Post-retirement costs increased by £29 million primarily due to reductions in discount rates. Bad debt expense reduced by £33 million in the year due to improving economic conditions and improved collections.

Depreciation and amortisation increased by £17 million as a result of our capital expenditure programme in the year. Finally, other costs increased by £58 million due to increased property tax rates and assessed values, together with higher environmental costs in 2012/13. As a result, adjusted operating profit for the year was £1,254 million.

Other activities

Our Other activities were significantly affected by the cost of major storms in the year, with an additional £51 million cost incurred compared with the prior year. This was as a result of insurance costs for Superstorm Sandy incurred in our insurance captive. Some of these costs are expected to be recovered from the reinsurance market.

Our metering business made £24 million lower operating profit than the prior year as a result of the disposal of OnStream in 2012, together with the impact of third-party disputes on legacy meter pricing in our regulated metering business.

Other costs increased by £126 million, primarily representing spend on the implementation of the new US information systems and financial procedures, offset by increased revenues from the French interconnector. As a result of these movements, Other activities recorded an adjusted operating profit of £11 million for the year.

Analysis of the statement of financial position for the year ended 31 March 2013 Goodwill and other intangible assets Goodwill and intangibles increased by £295 million to £5,617 million as at 31 March 2013. This increase primarily related to foreign exchange movements of £266 million and software additions of £175 million offset by amortisation of £101 million. Property, plant and equipment Property, plant and equipment increased by £2,891 million to £36,592 million as at 31 March 2013. This was principally due to capital expenditure of £3,511 million on the extension of our regulated networks and foreign exchange movements of	Other non-current liabilities decreased by £37 million to £1,884 million, reflecting changes in the fair value of US commodity contract liabilities. Net debt Net debt is the aggregate of cash and cash equivalents, current financial and other investments, borrowings, and derivative financial assets and liability. At 31 March 2013, net debt had increased by £1,832 million to £21,429 million as a result of debt issuances in the year, including the hybrid bonds of £2.1 billion. Net pension and other post-retirement obligations A summary of the total UK and US assets and liabilities and the overall net IAS 19 accounting deficit (as restated for IAS 19 (revised)) is shown below:
£680 million, offset by £1,281 million of depreciation in the year. Capital expenditure increased in each of the three regulated businesses including record amounts in our UK Transmission and US Regulated businesses. Investments and other non-current assets Investments in joint ventures and associates, financial and other investments and other non-current assets increased by £66 million to £753 million. This was principally due to changes in the fair value of our US commodity contract assets and available-for-sale investments, and an equity investment in Clean Line Energy Partners LLC of $12.5 million by 31 March 2013.

Inventories and current intangible assets, and trade and other receivables increased by £854 million to £3,201 million at 31 March 2013. Driven by the US, this primarily reflected the timing of cost recoveries from LIPA relating to Superstorm Sandy and an increase in trade receivables due to colder weather in February and March 2013 compared with 2012, which also led to an offsetting decrease in inventories which were £85 million lower. Trade and other payables Trade and other payables increased by £366 million to £3,051 million due to increased payables and accruals relating to Superstorm Sandy and Storm Nemo. Current tax liabilities Current tax liabilities of £231 million at 31 March 2013 were £152 million lower primarily due to higher tax payments made in 2012/13 and larger prior year tax credits arising in 2012/13, although these were partially offset by a larger current year tax charge. Deferred tax liabilities The net deferred tax liability increased by £341 million to £4,077 million. The main reasons for this movement were the £441 million deferred tax charge, including the impact of the reduction in the statutory tax rate for future periods of £128 million, partially offset by the deferred tax credit on actuarial losses on pensions and other post-retirement benefits. Provisions and other non-current liabilities Provisions (both current and non-current) increased by £29 million to £1,760 million as at 31 March 2013. The underlying movements included additions of £92 million and £83 million to the environmental and other provisions respectively, as well as foreign exchange movements of £65 million. The other provisions additions included £33 million of increased liabilities insured by our insurance subsidiaries. These were offset by payments of £231 million in relation to all classes of provisions.	The principal movements in net obligations during the year arose as a consequence of a decrease in the discount rate following declines in corporate bond yields. Actuarial gains on plan assets reflected improvements in financial markets. Commitments and contingencies Capital expenditure contracted but not provided for increased by £283 million to £3,011 million a result of the continued ramp up in our capital investment programme. Off balance sheet items There were no significant off balance sheet items other than the contractual obligations shown in note 30 (b) on page 139.

These forward-looking statements are not guarantees of our future performance and are subject to assumptions, risks and uncertainties that could cause actual future results to differ materially from those expressed in or implied by such forward-looking statements. Many of these assumptions, risks and uncertainties relate to factors that are beyond our ability to control or estimate precisely, such as changes in laws or regulations, announcements from and decisions by governmental bodies or regulators (including the timeliness of consents for construction projects); the timing of construction and delivery by third parties of new generation projects requiring connection; breaches of, or changes in, environmental, climate change and health and safety laws or regulations, including breaches or other incidents arising

from the potentially harmful nature of our activities; network failure or interruption, the inability to carry out critical non network operations and damage to infrastructure, due to adverse weather conditions including the impact of major storms as well as the results of climate change or due to the failure of or unauthorised access to or deliberate breaches of our IT systems and supporting technology; performance against regulatory targets and standards and against our peers with the aim of delivering stakeholder expectations regarding costs and efficiency savings, including those related to investment programmes and internal transformation projects (including our US financial systems and our controls over financial reporting); and customers and counterparties (including financial institutions) failing to perform their obligations to the Company. Other factors that could cause actual results to differ materially from those described in this document include fluctuations in exchange rates, interest rates and commodity price indices; restrictions and conditions (including filing requirements) in our borrowing and debt arrangements, funding costs and access to financing; regulatory requirements for us to maintain financial resources in certain parts of our business and restrictions on some subsidiaries’ transactions such as paying dividends, lending or levying charges; inflation; the delayed timing of recoveries and payments in our regulated businesses and whether aspects of our activities are contestable; the funding requirements and performance of our pension schemes and other post-retirement benefit schemes; the failure to attract, train or retain employees with the necessary competencies, including leadership skills, and any significant disputes arising with our employees or the breach of laws or regulations by our employees; and the failure to respond to market developments and grow our business to deliver our strategy, as well as incorrect or unforeseen assumptions or conclusions (including unanticipated costs and liabilities) relating to business development activity, including assumptions in connection with joint ventures.

For further details regarding these and other assumptions, risks and uncertainties that may affect National Grid, please read the Strategic Report and the Risk factors on pages 167 to 169 of this document. In addition, new factors emerge from time to time and we cannot assess the potential impact of any such factor on our activities or the extent to which any factor, or combination of factors, may cause actual future results to differ materially from those contained in any forward-looking statement.
