NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.	Description of Business and Summary of Significant Accounting Policies

Description of Business

CDW Corporation ("Parent") is a Fortune 500 company with multi-national capabilities and a leading provider of integrated information technology ("IT") solutions to small, medium and large business, government, education and healthcare customers in the United States ("US"), the United Kingdom ("UK") and Canada. The Company's offerings range from discrete hardware and software products to integrated IT solutions such as mobility, security, data center optimization, cloud computing, virtualization and collaboration.

Throughout this report, the terms the "Company" and "CDW" refer to Parent and its 100% owned subsidiaries.

Parent has two 100% owned subsidiaries, CDW LLC and CDW Finance Corporation. CDW LLC is an Illinois limited liability company that, together with its 100% owned subsidiaries, holds all material assets and conducts all business activities and operations of the Company. CDW Finance Corporation is a Delaware corporation formed for the sole purpose of acting as co-issuer of certain debt obligations as described in Note 13 (Supplemental Guarantor Information) and does not hold any material assets or engage in any business activities or operations.

Basis of Presentation

The accompanying unaudited interim Consolidated Financial Statements as of June 30, 2018 and for the three and six months ended June 30, 2018 and 2017 (the "Consolidated Financial Statements") have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and the rules and regulations of the US Securities and Exchange Commission (the "SEC") for interim financial statements. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. These Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 (the "December 31, 2017 Consolidated Financial Statements"). The significant accounting policies used in preparing these Consolidated Financial Statements were applied on a basis consistent with those reflected in the December 31, 2017 Consolidated Financial Statements except for changes from the adoption of Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers, as amended ("Topic 606"), as discussed below. In the opinion of management, the Consolidated Financial Statements contain all adjustments (consisting of a normal, recurring nature) necessary to present fairly the Company's financial position, results of operations, comprehensive income, cash flows and changes in stockholders' equity as of the dates and for the periods indicated. The unaudited results of operations for such interim periods reported are not necessarily indicative of results for the full year.

Effective January 1, 2018, the Company adopted the requirements of Topic 606 utilizing the full retrospective method as discussed in Note 2 (Recent Accounting Pronouncements). Prior period amounts have been adjusted accordingly.

Principles of Consolidation

The accompanying Consolidated Financial Statements include the accounts of Parent and its 100% owned subsidiaries. All intercompany transactions and accounts are eliminated in consolidation.

Use of Estimates

The preparation of the Consolidated Financial Statements in accordance with GAAP requires management to make use of certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the Consolidated Financial Statements and the reported amounts of revenue and expenses during the reported periods. The Company bases its estimates on historical experience and on various other assumptions that management believes are reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The notes to the Consolidated Financial Statements contained in the December 31, 2017 Consolidated Financial Statements include a discussion of the significant accounting policies and estimates used in the preparation of the Company's Consolidated Financial Statements. Except as noted above for the adoption of Topic 606, there have been no material changes to the Company's significant accounting policies and estimates during the six months ended June 30, 2018.

Revenue Recognition

The Company is a primary distribution channel for a large group of vendors and suppliers, including original equipment manufacturers ("OEMs"), software publishers and wholesale distributors.

The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are established, the contract has commercial substance and collectability of consideration is probable. The Company evaluates the following indicators amongst others when determining whether it is acting as a principal in the transaction and recording revenue on a gross basis: (i) the Company is primarily responsible for fulfilling the promise to provide the specified goods or service, (ii) the Company has inventory risk before the specified good or service has been transferred to a customer or after transfer of control to the customer and (iii) the Company has discretion in establishing the price for the specified good or service. If the terms of a transaction do not indicate the Company is acting as a principal in the transaction, then the Company is acting as an agent in the transaction and the associated revenues are recognized on a net basis.

The Company recognizes revenue once control has passed to the customer. The following indicators are evaluated in determining when control has passed to the customer: (i) the Company has a right to payment for the product or service, (ii) the customer has legal title to the product, (iii) the Company has transferred physical possession of the product to the customer, (iv) the customer has the significant risk and rewards of ownership of the product and (v) the customer has accepted the product. The Company's products can be delivered to customers in a variety of ways, including (i) as physical product shipped from the Company's warehouse, (ii) via drop-shipment by the vendor or supplier or (iii) via electronic delivery of keys for software licenses. The Company’s shipping terms typically specify F.O.B. destination.

The Company leverages drop-shipment arrangements with many of its vendors and suppliers to deliver products to its customers without having to physically hold the inventory at its warehouses. The Company is the principal in the transaction and recognizes revenue for drop-shipment arrangements on a gross basis.

Revenue Recognition for Hardware

Revenues from sales of hardware products are recognized on a gross basis as the Company is acting as a principal in these transactions, with the selling price to the customer recorded as Net sales and the acquisition cost of the product recorded as Cost of sales. The Company recognizes revenue from these transactions when control has passed to the customer, which is usually upon delivery of the product to the customer.

In some instances, the customer agrees to buy the product from the Company but requests delivery at a later date, commonly known as bill-and-hold arrangements. For these transactions, the Company deems that control passes to the customer when the product is ready for delivery. The Company views products ready for delivery when the customer has a signed agreement, significant risk and rewards for the products, the ability to direct the assets, the products have been set aside specifically for the customer, cannot be redirected to another customer and for customer orders that include configuration services, when such services have been completed.

The Company's vendor partners warrant most of the products the Company sells. These manufacturer warranties are assurance-type warranties and are not considered separate performance obligations. The warranties are not sold separately and only provide assurance that products will conform with the manufacturer's specifications. In some transactions, a third-party will provide the customer with an extended warranty. These extended warranties are sold separately and provide the customer with a service in addition to assurance that the product will function as expected. The Company considers these service-type warranties to be separate performance obligations from the underlying product. For service-type warranties, the Company is arranging for those services to be provided by the third-party and therefore is acting as an agent in the transaction and records revenue on a net basis at the point of sale.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Revenue Recognition for Software

Revenues from most software license sales are recognized as a single performance obligation on a gross basis as the Company is acting as a principal in these transactions at the point the software license is delivered to the customer. Generally, software licenses are sold with accompanying third-party delivered software assurance, which is a product that allows customers to upgrade, at no additional cost, to the latest technology if new capabilities are introduced during the period that the software assurance is in effect. The Company evaluates whether the software assurance is a separate performance obligation by assessing if the third-party delivered software assurance is critical or essential to the core functionality of the software itself. This involves considering if the software provides its original intended functionality to the customer without the updates, if the customer would ascribe a higher value to the upgrades versus the up-front deliverable, if the customer would expect frequent intelligence updates to the software (such as updates that maintain the original functionality), and if the customer chooses to not delay or always install upgrades. If the Company determines that the accompanying third-party delivered software assurance is critical or essential to the core functionality of the software license, the software license and the accompanying third-party delivered software assurance are recognized as a single performance obligation. The value of the product is primarily the accompanying support delivered by a third-party and therefore the Company is acting as an agent in these transactions and recognizes them on a net basis at the point the associated software license is delivered to the customer. For software licenses where the accompanying third-party delivered software assurance is not critical or essential to the core functionality, the software assurance is recognized as a separate performance obligation, with the associated revenue recognized on a net basis at the point the related software license is delivered to the customer. For additional details regarding the accounting for bundled arrangements, see "Revenue Recognition for Bundled Arrangements" below.

Revenue Recognition for Services

The Company provides professional services, which include project managers and consultants recommending, designing and implementing IT solutions. Revenue from professional services is recognized either on a time and materials basis or recognized proportionally as costs are incurred for fixed fee project work. For time and materials projects, revenue is recognized on a gross basis each month as work is performed and the Company transfers those services.

The Company sells cloud computing solutions, which include Software as a Service ("SaaS") and Infrastructure as a Service ("IaaS"). SaaS solutions utilize third-party partners to offer the Company's customers access to software in the cloud that enhances office productivity, provides security or assists in collaboration. IaaS solutions utilize third-party partners to enable customers to access data center functionality in a cloud-based solution, including storage, computing and networking. The Company recognizes revenue for cloud computing solutions for arrangements with one-time invoicing to the customer at the time of invoice on a net basis as the Company is acting as an agent in the transaction. For monthly subscription-based arrangements, the Company is acting as an agent in the transaction and recognizes revenue as it invoices the customer for its monthly usage on a net basis.

Revenues from the sale of data center services, such as managed and remote managed services, server co-location, internet connectivity and data backup and storage provided by the Company, are recognized over the period the service is provided. Most hosting and managed service obligations are based on the quantity and pricing parameters established in the agreement. As the customer receives the benefit of the service each month, the Company recognizes the respective revenue on a gross basis as the Company is acting as a principal in the transaction. Additionally, the Company's managed services team provides project support to customers that are billed on a fixed fee basis. The Company is acting as the principal in the transaction and recognizes revenue on a gross basis based on the total number of hours incurred for the period over the total expected hours for the project. Total expected hours to complete the project is updated for each period and best represents the transfer of control of the service to the customer.

The Company's customers are offered the opportunity by certain of its vendors to purchase software licenses and software assurance under enterprise agreements ("EAs"), referred to as services in this paragraph. For most EA transactions, the Company's obligation to the customer is that of a distributor or sales agent of the services, where all obligations for providing the services to customers are passed to the Company's vendors. The Company's performance obligations are satisfied at the time of the sale. In other EA transactions, the Company is responsible for fulfilling the promised services to the customer and providing remedy or refund for work if the customer is not satisfied with the delivered services, has inventory risk in the arrangement and has full control to set the price for the customer. This results in the Company acting as a principal in the agreement. With most EAs, the Company's vendors will transfer the license and invoice the customer

directly, paying resellers an agency fee or commission on these sales. The Company records these fees as a component of Net sales as earned and there is no corresponding Cost of sales amount.

Revenue Recognition for Bundled Arrangements

The Company also sells some of its products and services as part of bundled contract arrangements containing multiple deliverables, which may include a combination of products and services. For each deliverable that represents a distinct performance obligation, total arrangement consideration is allocated based upon the standalone selling prices of each performance obligation. The Company excludes amounts collected on behalf of third-parties, such as sales taxes, when determining the transaction price. For certain performance obligations, the Company will use a combination of methods to estimate the standalone selling price. When evidence from recent transactions is not available to confirm that the prices are representative of the standalone selling price, an expected cost plus a margin approach is used.

Sales In-Transit

The Company performs an analysis of the estimated number of days of sales in-transit to customers at the end of each reporting period based on a weighted-average analysis of commercial delivery terms that include drop-shipment arrangements. This analysis is the basis upon which the Company estimates the amount of Net sales in-transit at the end of the period and adjusts revenue and the related costs to reflect only what has been delivered to the customer. Changes in delivery patterns may result in a different number of business days estimated to make this adjustment.

Freight Costs

The Company records freight billed to its customers as Net sales and the related freight costs as a Cost of sales when the underlying product revenue is recognized. For freight not billed to its customers, the Company records the freight costs as a Cost of sales. The Company's typical shipping terms are F.O.B. destination, which results in shipping being performed before the customer obtains control of the product. The Company considers shipping to be a fulfillment activity and not a separate performance obligation.

Other

The nature of the Company's contracts give rise to variable consideration in the form of sales returns and allowances. The Company estimates variable consideration at the most likely amount to which it is expected to be entitled. This estimated amount is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based on an assessment of the Company's anticipated performance and all information that is reasonably available. At the time of sale, the Company records an estimate for sales returns and allowances and an associated right of return asset based on historical experience.

When a contract results in revenue being recognized in excess of the amount the Company has the right to invoice to the customer, a contract asset is recorded on the balance sheet. Contract assets are comprised primarily of professional services with fixed fee arrangements.

Contract liabilities consist of payments received from customers, or such consideration that is contractually due, in advance of providing the product or performing services. Contract liabilities are comprised primarily of professional services with fixed fee arrangements, bill-and-hold transactions where control has not passed to the customer and certain governmental contracts.

Trade accounts receivable are recorded at the point of sale (or in accordance with the Statement of Work for services) for the total amount payable by the customer to the Company for sale of goods. Taxes to be collected from the customer as part of the sale are included in Accounts receivable.

Any incremental direct costs of obtaining a contract, primarily sales commissions, are deferred on the Consolidated Balance Sheets and amortized over the period of contract performance.

The Company typically does not enter into long-term contracts. The Company has elected to use the practical expedient for its performance obligations table to show only those contracts that are longer than 12 months at the time of contract inception and those contracts that are non-cancelable. Additionally, for certain governmental contracts where there are

annual renewals, the Company has excluded these contracts since there is only a one-year legal obligation. Typically, the only contracts that are longer than 12 months in duration are related to the Company's professional and managed services business.

The Company requests payments for its products and services at the point of sale. The Company generally does not enter into any long-term financing arrangements or payment plans with customers or contracts with customers that have non-cash consideration.


2.	Recent Accounting Pronouncements

Accounting for Hedging Activities

In August 2017, the Financial Accounting Standards Board (the "FASB") issued ASU 2017-12, Derivatives and Hedging (Topic 815), intending to improve the transparency of information included in the financial statements by aligning cash flow and fair value hedge accounting with its risk management activities. The ASU eliminates the requirement to separately measure and report hedge ineffectiveness for cash flow hedges and net investment hedges, and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The ASU also simplifies certain documentation and assessment requirements, and will incorporate new disclosure requirements and amendments to existing disclosures. This ASU is effective for the Company beginning the first quarter of 2019 and allows for early adoption. The Company is currently evaluating the impact the ASU will have on its Consolidated Financial Statements.

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU introduces a new forward-looking approach, based on expected losses, to estimate credit losses on certain types of financial instruments, including trade receivables. The estimate of expected credit losses will require considerations of historical information, current information and reasonable and supportable forecasts. This ASU also expands the disclosure requirements to enable users of financial statements to understand the assumptions, models and methods for estimating expected credit losses. This ASU is effective for the Company beginning in the first quarter of 2020 and allows for early adoption beginning in the first quarter of 2019. The Company is currently evaluating the impact the ASU will have on its Consolidated Financial Statements.

Accounting for Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), requiring lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by long-term leases and to disclose additional quantitative and qualitative information about leasing arrangements. This ASU is effective for the Company beginning in the first quarter of 2019 and allows for early adoption. A modified retrospective transition approach is required for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements.

The Company has established a cross-functional implementation team to analyze the effect of the ASU. The Company is utilizing a combination of a bottom-up and top-down approach to identify and analyze its lease portfolio. The Company is in the process of evaluating its identified leases. In addition, the Company is evaluating business processes and internal controls to meet the ASU’s accounting, reporting and disclosure requirements. Although the Company is currently evaluating the provisions of the ASU to determine how it will be affected, the primary impact to the Company of the new ASU will be to record assets and liabilities for current operating leases, which are principally related to the Company's real estate portfolio.

Revenue Recognition

On January 1, 2018, the Company adopted Topic 606 and utilized the full retrospective method. For additional details, see Note 1 (Description of Business and Summary of Significant Accounting Policies).

4. Contract Liabilities and Remaining Performance Obligations

The Company's contract liabilities consist of payments received from customers, or such consideration that is contractually due, in advance of providing the product or performing services. The Company's contract liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. As of June 30, 2018 and December 31, 2017, the contract liability balance was $170 million and $159 million, respectively. During the six months ended June 30, 2018 and 2017, the Company recognized revenue of $116 million and $99 million, respectively, related to its contract liabilities.

A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. For more information regarding the Company's performance obligations, see Note 1 (Description of Business and Summary of Significant Accounting Policies). The following table represents the total transaction price for the remaining performance obligations as of June 30, 2018 related to non-cancelable contracts longer than 12 months in duration that is expected to be recognized over future periods.

Remaining performance obligations	$	33.6	$	20.8	$	6.2	$	0.9


5.	Financial Instruments

The Company's indebtedness creates interest rate risk on its variable-rate debt. The Company uses derivative financial instruments to manage its exposure to interest rate risk. The Company does not hold or issue derivative financial instruments for trading or speculative purposes.

The Company has interest rate cap agreements that entitle it to payments from the counterparty of the amount, if any, by which three-month LIBOR exceeds the strike rates of the caps during the agreement period in exchange for an upfront premium. During the first quarter of 2018, the Company entered into interest rate cap agreements with a combined notional value of $1.4 billion resulting in premiums paid to the counterparties of $13 million. As of June 30, 2018 and December 31, 2017, the Company had the following interest rate cap agreements for which the fair values are classified within Other assets on the Consolidated Balance Sheets:



				June 30, 2018		December 31, 2017
Notional Value (in millions)		Effective Date	Maturity Date	Fair Value (in millions)		Fair Value (in millions)
$	1,400.0	January 17, 2017	December 31, 2018	$	6.4	$	5.4
1,400.0		December 31, 2018	December 31, 2020	17.1		—
				$	23.5	$	5.4

The fair value of the Company's interest rate cap agreements is classified as Level 2 in the fair value hierarchy. The valuation of the interest rate cap agreements is derived by using a discounted cash flow analysis on the expected cash receipts that would occur if variable interest rates rise above the strike rates of the caps. This analysis reflects the contractual terms of the interest rate cap agreements, including the period to maturity, and uses observable market-based inputs, including LIBOR curves and implied volatilities. The Company also incorporates insignificant credit valuation adjustments to appropriately reflect the respective counterparty's nonperformance risk in the fair value measurements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The counterparty credit spreads are based on publicly available credit information obtained from a third-party credit data provider. For additional details, see Note 6 (Long-Term Debt).

The interest rate cap agreements are designated as cash flow hedges. The effective portion of changes in the fair value of derivatives that qualify as cash flow hedges is recorded in Accumulated other comprehensive loss and is subsequently reclassified into Interest expense in the period when the hedged forecasted transaction affects earnings. If a derivative is deemed to be ineffective, the ineffective portion of the change in fair value of the derivative is recognized directly into earnings. The Company's interest rate cap agreements were deemed effective during both the six months ended June 30, 2018 and 2017, and the Company expects the derivatives will continue to be effective for the next twelve months. During the three and six months ended June 30, 2018, the Company recorded a gain of $2 million and $5 million, respectively, net of a tax expense for the effective portion of the interest rate cap agreements into Accumulated other comprehensive loss. During the three and six months ended June 30, 2017, the Company recorded a loss of $1 million and $2 million respectively, net of a tax benefit, for the effective portion of the interest rate cap agreements into Accumulated other comprehensive loss. During the three and six months ended June 30, 2018, the Company reclassified $1 million and $2 million, respectively, from Accumulated other comprehensive loss to earnings within Interest expense, net on the Consolidated Statement of Operations. The Company expects to reclassify $5 million from Accumulated other comprehensive loss into Interest expense, net during the next twelve months.

Prior to the election of hedge accounting treatment during the first quarter of 2017, the Company recognized less than $1 million of Interest income during the six months ended June 30, 2017 in the Company's Consolidated Statement of Operations related to the changes in the fair value of the interest rate cap agreements.

Senior Secured Asset-based Revolving Credit Facility ("Revolving Loan")

As of June 30, 2018, the Company had no outstanding borrowings under the Revolving Loan, less than $1 million of undrawn letters of credit, $357 million reserved for the floorplan sub-facility and a borrowing base of $1.8 billion, which is based on the amount of eligible inventory and accounts receivable balances as of May 31, 2018. Borrowings under the Revolving Loan are limited by the borrowing base. As of June 30, 2018, the Company could have borrowed up to an additional $1.1 billion under the Revolving Loan. Borrowings are also limited by a minimum liquidity condition, which provides that, if excess cash availability is less than the lower of (i) $125 million and (ii) the greater of (a) 10.0% of the borrowing base, and (b) $100 million, the lenders are not required to lend additional amounts under the Revolving Loan unless the consolidated fixed charge coverage ratio, as defined, is at least 1.00 to 1.00.

Borrowings under the Revolving Loan bear interest at a variable interest rate plus an applicable margin. The interest rate margin is based on one of two indices, either (i) LIBOR or (ii) the Alternate Base Rate ("ABR"), with the ABR being the greater of (a) the prime rate, (b) the federal funds effective rate plus 50 basis points or (c) the one-month LIBOR plus 1.00%. The applicable margin varies (1.25% to 1.75% for LIBOR borrowings and 0.25% to 0.75% for ABR borrowings) depending upon average daily excess cash availability under the agreement evidencing the Revolving Loan.

During the six months ended June 30, 2017, the Company amended, extended and increased its prior revolving loan ("Prior Revolving Loan") and recorded a loss on extinguishment of long-term debt of $1 million in the Consolidated Statement of Operations, representing a write-off of a portion of unamortized deferred financing fees. Fees of $4 million related to the Prior Revolving Loan were capitalized as deferred financing fees and are being amortized over the five-year term of the facility on a straight-line basis. These deferred financing fees are recorded in the Other assets line on the Consolidated Balance Sheets.

Senior Secured Term Loan Facility ("Term Loan")

On April 3, 2018, the Company amended the Term Loan, reducing interest margins by 25 basis points. Borrowings under the Term Loan continue to bear interest at either (i) LIBOR plus a margin or (ii) the Alternative Base Rate ("ABR"), with the ABR being the greater of (a) the prime rate, (b) the federal funds effective rate plus 50 basis points or (c) the one-month LIBOR plus a margin. The amended margin is 1.75% for LIBOR borrowings and 0.75% for ABR borrowings effective April 3, 2018. Additionally, the Company amended its covenant on restricted payments, such that the Company is permitted to make restricted payments so long as the total net leverage ratio is less than 3.75:1.00 on a pro forma basis.

The proceeds from the issuance of the 2025 Senior Notes along with cash on hand and proceeds from Revolving Loan borrowings were deposited to redeem all of the then remaining $600 million aggregate principal amount of the 2022 Senior Notes ("2022 Senior Notes"). In connection with this redemption, the Company recorded a loss on extinguishment of long-term debt of $43 million in the Consolidated Statement of Operations for the six months ended June 30, 2017. This loss represents $37 million in redemption premium and $6 million for the write-off of the remaining deferred financing fees related to the 2022 Senior Notes.

7. Income Taxes

On December 22, 2017, the Tax Cuts and Jobs Act was enacted into law. The Tax Cuts and Jobs Act changes several aspects of US federal tax law including: reducing the US corporate income tax rate from 35.0% to 21.0% beginning on January 1, 2018; a one-time tax on the deemed mandatory repatriation of the Company's unremitted foreign earnings which have not been subject to US tax; imposing a minimum US tax on foreign earnings; providing for the immediate expensing of certain qualified property; and changing the tax treatment of performance-based executive compensation and certain employee fringe benefits.

The SEC issued Staff Accounting Bulletin 118 allowing for provisional amounts to be recorded during a measurement period not to exceed one year. The Company recorded during the year ended December 31, 2017 provisional amounts for the impact of revaluing deferred tax assets and liabilities, the deemed mandatory repatriation tax on the Company's unremitted foreign earnings and the state income tax effects from the change in federal tax law during the year ended December 31, 2017. The Company did not adjust any of the provisional amounts during the three or six months ended June 30, 2018. The Company continues to analyze the income tax effects of the Tax Cuts and Jobs Act, as well as monitor guidance from the Internal Revenue Service, US Treasury Department and state taxing authorities and will adjust the provisional amounts within the one-year measurement period.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A reconciliation of basic weighted-average shares outstanding to diluted weighted-average shares outstanding is as follows:



	Three Months Ended June 30,		Six Months Ended June 30,
(in millions)	2018	2017	2018	2017
Basic weighted-average shares outstanding	151.6	156.0	151.9	157.7
Effect of dilutive securities⁽¹⁾	2.3	3.0	2.5	3.2
Diluted weighted-average shares outstanding⁽²⁾	153.9	159.0	154.4	160.9


(1)	The dilutive effect of outstanding stock options, restricted stock units, restricted stock, performance share units and Coworker Stock Purchase Plan units is reflected in the diluted weighted-average shares outstanding using the treasury stock method.


(2)	There were fewer than 0.2 million potential common shares excluded from diluted weighted-average shares outstanding for both the three and six months ended June 30, 2018 and 2017 as their inclusion would have had an anti-dilutive effect.

11. Commitments and Contingencies

The Company is party to various legal proceedings that arise in the ordinary course of its business, which include commercial, intellectual property, employment, tort and other litigation matters. The Company is also subject to audit by federal, state, international, national, provincial and local authorities, and by various partners, group purchasing organizations and customers, including government agencies, relating to purchases and sales under various contracts. In addition, the Company is subject to indemnification claims under various contracts. From time to time, certain customers of the Company file voluntary petitions for reorganization or liquidation under the US bankruptcy laws or similar laws of the jurisdictions for the Company's business activities outside of the US. In such cases, certain pre-petition payments received by the Company could be considered preference items and subject to return to the bankruptcy administrator.

As of June 30, 2018, the Company does not believe that there is a reasonable possibility that any material loss exceeding the amounts already recognized for these proceedings and matters, if any, has been incurred. However, the ultimate resolutions of these proceedings and matters are inherently unpredictable. As such, the Company's financial condition and results of operations could be adversely affected in any particular period by the unfavorable resolution of one or more of these proceedings or matters.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

Unless otherwise indicated or the context otherwise requires, as used in this "Management's Discussion and Analysis of Financial Condition and Results of Operations," the terms "we," "us," "the Company," "our," "CDW" and similar terms refer to CDW Corporation and its subsidiaries. "Management's Discussion and Analysis of Financial Condition and Results of Operations" should be read in conjunction with the unaudited interim Consolidated Financial Statements and the related notes included elsewhere in this report and with the audited Consolidated Financial Statements and the related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017. This discussion contains forward-looking statements that are subject to numerous risks and uncertainties. Actual results may differ materially from those contained in any forward-looking statements. See "Forward-Looking Statements" at the end of this discussion.

Overview

CDW Corporation ("Parent") is a Fortune 500 company and a leading provider of integrated information technology ("IT") solutions to small, medium and large business, and government, education and healthcare customers in the United States ("US"), the United Kingdom ("UK") and Canada. Our broad array of offerings ranges from discrete hardware and software products to integrated IT solutions such as mobility, security, data center optimization, cloud computing, virtualization and collaboration.

We are technology "agnostic," with a portfolio including more than 100,000 products and services from more than 1,000 leading and emerging brands. Our solutions are delivered in physical, virtual and cloud-based environments through over 6,000 customer-facing coworkers, including sellers, highly-skilled technology specialists and advanced service delivery engineers. We are a leading sales channel partner for many original equipment manufacturers ("OEMs"), software publishers and cloud providers (collectively, our "vendor partners"), whose products we sell or include in the solutions we offer. We provide our vendor partners with a cost-effective way to reach customers and deliver a consistent brand experience through our established end-market coverage, technical expertise and extensive customer access.

We have three reportable segments, Corporate, Small Business and Public. Our Corporate segment primarily serves US private sector business customers with more than 250 employees. Our Small Business segment primarily serves US private sector business customers with up to 250 employees. Our Public segment is comprised of government agencies and education and healthcare institutions in the US. We also have two other operating segments: CDW UK and CDW Canada, each of which do not meet the reportable segment quantitative thresholds and, accordingly, are included in an all other category ("Other").

We may sell all or only select products that our vendor partners offer. Each vendor partner agreement provides for specific terms and conditions, which may include one or more of the following: product return privileges, price protection policies, purchase discounts and vendor incentive programs, such as purchase or sales rebates and cooperative advertising reimbursements. We also resell software for major software publishers. Our agreements with software publishers allow the end-user customer to acquire software or licensed products and services. In addition to helping our customers determine the best software solutions for their needs, we help them manage their software agreements, including warranties and renewals. A significant portion of our advertising and marketing expenses are reimbursed through cooperative advertising programs with our vendor partners. These programs are at the discretion of our vendor partners and are typically tied to sales or other commitments to be met by us within a specified period of time.

Effective January 1, 2018, we adopted the requirements of ASU 2014-09, Revenue from Contracts with Customers, as amended ("Topic 606"), utilizing the full retrospective method as discussed in Note 2 (Recent Accounting Pronouncements) to the accompanying Consolidated Financial Statements. Prior period amounts have been adjusted accordingly.

Key factors affecting our financial performance

We believe the following key factors may have a meaningful impact on our business performance, influencing our ability to generate sales and achieve our targeted financial and operating results:

•

General economic conditions are a key factor affecting our results as they impact our customers’ willingness to spend on information technology. This is particularly the case for business customers, as their purchases tend to reflect confidence in their business prospects, which are driven by their perceptions of business conditions. Purchasing behavior may be different between our Corporate customers and Small Business customers due to their perception of business conditions. Additionally, changes in trade policy could have an adverse impact on our business.


•	Changes in spending policies, budget priorities and funding levels are a key factor influencing the purchasing levels of government, healthcare and education customers.

Table of Contents


•	Technology trends drive customer purchasing behaviors in the market. Current technology trends are focused on delivering greater flexibility and efficiency, as well as designing IT securely. These trends are driving customer adoption of solutions such as those delivered via cloud, software defined architectures and hybrid on-premise and off-premise combinations.

Key business metrics

We monitor a number of financial and non-financial measures and ratios on a regular basis in order to track the progress of our business and make adjustments as necessary. We believe that the most important of these measures and ratios include average daily sales, gross margin, operating margin, Net income, Non-GAAP income before income taxes, Non-GAAP net income, Net income per common share, Non-GAAP net income per diluted share, EBITDA, Adjusted EBITDA, Adjusted EBITDA margin, free cash flow, return on working capital, Cash and cash equivalents, net working capital, cash conversion cycle (defined to be days of sales outstanding in Accounts receivable plus days of supply in Inventory minus days of purchases outstanding in Accounts payable, based on a rolling three-month average), debt levels including available credit and leverage ratios, sales per coworker and coworker turnover. These measures and ratios are compared to standards or objectives set by management, so that actions can be taken, as necessary, in order to achieve the standards and objectives.

In this Form 10-Q, we discuss Non-GAAP income before income taxes, Non-GAAP net income, Non-GAAP net income per diluted share, EBITDA, Adjusted EBITDA and Adjusted EBITDA margin, which are non-GAAP financial measures.

We believe these measures provide analysts, investors and management with helpful information regarding the underlying operating performance of our business, as they remove the impact of items that management believes are not reflective of underlying operating performance. Management uses these measures to evaluate period-over-period performance as management believes they provide a more comparable measure of the underlying business. Additionally, Adjusted EBITDA is a measure in the credit agreement governing our Senior Secured Term Loan Facility ("Term Loan"), which is used to evaluate our ability to make certain investments, incur additional debt, and make restricted payments, such as dividends and share repurchases, as well as whether we are required to make additional principal prepayments on the Term Loan beyond the quarterly amortization payments. For further details regarding the Term Loan, see Long-Term Debt and Financing Arrangements within Management's Discussion and Analysis of Financial Condition and Results of Operations and Note 6 (Long-Term Debt) to the accompanying Consolidated Financial Statements. For the definitions of Non-GAAP income before income taxes, Non-GAAP net income and Adjusted EBITDA and reconciliations to Net income, see "Results of Operations."

The results of certain business metrics are as follows:

(2)	There were 64 selling days for both the three months ended June 30, 2018 and 2017.

Total Net sales for the three months ended June 30, 2018 increased $294 million, or 7.6%, to $4,186 million, compared to $3,892 million for the three months ended June 30, 2017. Excluding the impact of foreign currency fluctuations, constant currency Net sales growth was 7.0%. See "Non-GAAP Financial Measure Reconciliations" below for additional information regarding constant currency Net sales growth.

For the three months ended June 30, 2018, ongoing focus on client device refresh across all customer-end markets, except Federal, coupled with strong results from our international operations, drove Net sales growth.

Corporate segment Net sales for the three months ended June 30, 2018 increased $154 million, or 9.7%, compared to the three months ended June 30, 2017. Growth was primarily driven by client device refresh, as well as ongoing success helping customers with solutions, including data center and software.

Small Business segment Net sales for the three months ended June 30, 2018 increased by $15 million, or 4.6%, between periods. Sales growth was primarily driven by client device refresh.

Public segment Net sales for the three months ended June 30, 2018 increased $3 million, or 0.2%, compared to the three months ended June 30, 2017. The growth was primarily driven by Healthcare, which offset declines in sales to Government customers. Net sales in Healthcare increased 6.3%, primarily driven by performance in desktops and video products as customers move forward on refresh projects. The decline in sales to Federal government customers primarily reflected lower client device sales. This was partially offset by sales to State & Local government customers, which were primarily driven by client device refresh. Education Net sales increased 1.0%.

Net sales in Other, which is comprised of results from our UK and Canadian operations, for the three months ended June 30, 2018 increased $124 million, or 34.0%, compared to the three months ended June 30, 2017. Both operations had strong growth in local currency as we continued to take share in the local markets. In addition, UK growth was driven in part by increased sales from referrals for US-based customers. The impact of foreign currency exchange increased Other sales growth by approximately 700 basis points, due to the favorable impact resulting from the British pound and Canadian dollar to US dollar translations.

Gross profit

Gross profit increased $55 million, or 8.6%, to $696 million for the three months ended June 30, 2018, compared to $641 million for the three months ended June 30, 2017. As a percentage of Net sales, Gross profit margin increased 10 basis points to 16.6% for the three months ended June 30, 2018. Gross profit margin improvement primarily reflected the positive impact on product margin due to customer mix.

Selling and administrative expenses

Selling and administrative expenses increased $17 million, or 4.9%, to $381 million for the three months ended June 30, 2018, compared to $364 million for the three months ended June 30, 2017. This was driven by higher sales payroll costs, including sales commissions primarily due to higher Gross profit dollars, partially offset by lower equity-based compensation expense and the associated payroll taxes due to the vesting in the prior year of an equity grant made at the time of our initial public offering. Total coworker count was 8,917, up 130 from 8,787 at June 30, 2017. Total coworker count was 8,726 at December 31, 2017.

As a percentage of total Net sales, Selling and administrative expenses decreased 20 basis points to 9.1% during the three months ended June 30, 2018, down from 9.3% in the three months ended June 30, 2017.

Income from operations was $266 million for the three months ended June 30, 2018, an increase of $35 million, or 15.1%, compared to $231 million for the three months ended June 30, 2017. Income from operations increased primarily due to higher gross profit dollars, partially offset by higher sales payroll expenses. Total operating margin percentage increased 40 basis points to 6.3% for the three months ended June 30, 2018, from 5.9% for the three months ended June 30, 2017. Operating margin was positively impacted by the increase in Gross profit margin, driven by improved product margin. Also contributing to the increased operating margin percentage were lower equity-based compensation expenses and the associated payroll taxes, the non-recurrence of integration expenses in the current year and intangible asset amortization expenses as a percentage of Net sales, which do not trend in line with sales movement.

Corporate segment income from operations was $141 million for the three months ended June 30, 2018, an increase of $14 million, or 11.4%, compared to $127 million for the three months ended June 30, 2017.

percentage increased 10 basis points to 8.1% for the three months ended June 30, 2018, from 8.0% for the three months ended June 30, 2017. This increase in operating margin percentage was primarily driven by the benefit of lower Selling and administrative expenses as a percentage of Net sales. This was partially offset by product margin compression due to increased hardware sales.

Small Business segment income from operations was $25 million for the three months ended June 30, 2018, an increase of $6 million, or 26.8%, compared to $19 million for the three months ended June 30, 2017. Small business segment income from operations increased primarily due to higher gross profit dollars driven by higher sales and product margin. Small Business segment operating margin percentage increased 130 basis points to 7.5% for the three months ended June 30, 2018, from 6.2% for the three months ended June 30, 2017. This increase in operating margin percentage was primarily driven by higher product margin and the benefit of lower sales payroll expenses as a percentage of Net sales.

Public segment income from operations was $113 million for the three months ended June 30, 2018, an increase of $8 million, or 8.0%, compared to $105 million for the three months ended June 30, 2017. Public segment income from operations increased primarily due to higher Gross profit dollars driven by improved product margin. Public segment operating margin percentage increased 50 basis points to 6.9% for the three months ended June 30, 2018, from 6.4% for the three months ended June 30, 2017. This increase in operating margin percentage was primarily driven by higher product margin and the benefit of lower sales payroll expenses as a percentage of Net sales.

Other income from operations was $22 million for the three months ended June 30, 2018, an increase of $9 million, or 73.7%, compared to $13 million for the three months ended June 30, 2017. Other income from operations increased primarily due to higher sales volumes and Gross profit as we continue to take share in the local markets, and favorable foreign exchange. Other operating margin percentage increased 110 basis points to 4.5% for the three months ended June 30, 2018, from 3.4% for the three months ended June 30, 2017. This increase was primarily due to lower sales payroll expenses and intangible asset amortization as a percentage of Net sales. Also contributing to the increased operating margin percentage is the non-recurrence of integration expenses in the current year.

Income tax expense

The lower effective tax rate for the three months ended June 30, 2018 as compared to the same period of the prior year was primarily attributable to the reduction in the US federal statutory rate, partially offset by lower excess tax benefits on equity-based compensation and a higher effective net state income tax rate primarily due to the reduced US federal benefit.

Non-GAAP Financial Measure Reconciliations

Non-GAAP income before income taxes and Non-GAAP net income exclude, among other things, charges related to the amortization of acquisition-related intangible assets, equity-based compensation and associated taxes, gains and losses from the extinguishment of debt and integration expenses. EBITDA is defined as consolidated net income before interest expense, net, income tax expense, depreciation and amortization. Adjusted EBITDA, which is a measure defined in our credit agreements, means EBITDA adjusted for certain items which are described in the table below. Adjusted EBITDA margin is defined as Adjusted EBITDA as a percentage of Net sales. Consolidated Net sales growth on a constant currency basis is defined as consolidated Net sales growth excluding the impact of foreign currency translation on net sales compared to the prior period.

Non-GAAP income before income taxes, Non-GAAP net income, EBITDA, Adjusted EBITDA, Adjusted EBITDA margin and consolidated Net sales growth on a constant currency basis are considered non-GAAP financial measures. Generally, a non-GAAP financial measure is a numerical measure of a company's performance or financial position that either excludes or includes amounts that are not normally included or excluded in the most directly comparable measure calculated and presented in accordance with GAAP. Non-GAAP measures used by management may differ from similar measures used by other companies, even when similar terms are used to identify such measures.

Table of Contents

We believe these measures provide analysts, investors and management with helpful information regarding the underlying operating performance of our business, as they remove the impact of items that management believes are not reflective of underlying operating performance. Management uses these measures to evaluate period-over-period performance as management believes they provide a more comparable measure of the underlying business. Additionally, Adjusted EBITDA is a measure in the credit agreement governing our Term Loan used to evaluate our ability to make certain investments, incur additional debt, and make restricted payments, such as dividends and share repurchases, as well as whether we are required to make additional principal prepayments on the Term Loan beyond the quarterly amortization payments. For further details regarding the Term Loan, see Note 6 (Long-Term Debt) to the accompanying Consolidated Financial Statements.

Non-GAAP net income

Non-GAAP net income was $213 million for the three months ended June 30, 2018, an increase of $50 million, or 30.8%, compared to $163 million for the three months ended June 30, 2017.

Excluding the impact of foreign currency fluctuations, constant currency Net sales growth was 8.2%. See "Non-GAAP Financial Measure Reconciliations" below for additional information regarding constant currency Net sales growth.

For the six months ended June 30, 2018, growth was driven by ongoing focus on client device refresh within hardware and strong growth from our international operations. In addition, increased sales of solutions-based hardware reflected both underlying demand as well as the impact of the reversal associated with supply chain issues experienced at the end of 2017.

Corporate segment Net sales for the six months ended June 30, 2018 increased $279 million, or 9.2% compared to the six months ended June 30, 2017. Growth was primarily driven by client device refresh, as well as ongoing success helping customers with solutions, including data center and software.

Public segment Net sales for the six months ended June 30, 2018 increased $79 million, or 2.8%, compared to the six months ended June 30, 2017. Net sales in Healthcare increased 6.8%, primarily driven by performance in desktops and video products as customers move forward on refresh projects. Net sales to Government customers grew at 1.5% and increased $14 million. Sales to State and Local government customers were driven by the success of executing against recently added contracts. This growth was partially offset by a decline in Federal sales primarily due to lower client device and networking sales. Education Net sales increased 1.0% as ongoing success addressing networking and client device needs in Higher Education was partially offset by K-12 networking performance.

Net sales in Other, which is comprised of results from our UK and Canadian operations, for the six months ended June 30, 2018 increased $237 million, or 32.3%, compared to the six months ended June 30, 2017. Both operations had strong growth in local currency as we continued to take share in the local markets. In addition, UK growth was driven in part by increased sales from referrals for US-based customers. The impact of foreign currency exchange increased Other sales growth by approximately 900 basis points, due to the favorable impact resulting from the British pound and Canadian dollar to US dollar translations.

Gross profit

Gross profit increased $105 million, or 8.8%, to $1,300 million for the six months ended June 30, 2018, compared to $1,194 million for the six months ended June 30, 2017. As a percentage of Net sales, Gross profit margin remained flat compared to the prior year at 16.7%. Gross profit margin was positively impacted by improved product margin due to the mix of customers. This was offset by lower partner funding margin due to year-over-year revenue growth out-pacing year-over-year increases in partner funding.

Selling and administrative expenses

Selling and administrative expenses increased $33 million, or 4.7%, to $744 million for the six months ended June 30, 2018, compared to $711 million for the six months ended June 30, 2017. This was driven by higher sales payroll costs, including sales commissions primarily due to higher Gross profit dollars. This was partially offset by lower equity-based compensation expense and the associated payroll taxes due to the vesting in the prior year of an equity grant made at the time of our initial public offering.

As a percentage of total Net sales, Selling and administrative expenses decreased 40 basis points to 9.5% during the six months ended June 30, 2018, down from 9.9% in the six months ended June 30, 2017.

(1)	Amounts for 2017 have been adjusted to reflect the adoption of Topic 606.


(2)	Segment income from operations includes the segment’s direct operating income, allocations for Headquarters’ costs, allocations for income and expenses from logistics services, certain inventory adjustments and volume rebates and cooperative advertising from vendors.

Income from operations was $470 million for the six months ended June 30, 2018, an increase of $68 million, or 16.9%, compared to $402 million for the six months ended June 30, 2017. Income from operations increased primarily due to higher gross profit dollars, partially offset by higher sales payroll expenses. Total operating margin percentage increased 40 basis points to 6.0% for the six months ended June 30, 2018, from 5.6% for the six months ended June 30, 2017. The increase was primarily due to lower equity-based compensation expense and the associated payroll taxes and intangible asset amortization as a percentage of Net sales, which do not trend in line with sales movement. Also contributing to the increased operating margin percentage were lower sales payroll expenses as a percentage of Net sales.

Corporate segment income from operations was $266 million for the six months ended June 30, 2018, an increase of $27 million, or 11.3%, compared to $239 million for the six months ended June 30, 2017. Corporate segment income from operations increased primarily due to higher gross profit dollars driven by higher sales. Corporate segment operating margin percentage

Table of Contents

increased 20 basis points to 8.1% for the six months ended June 30, 2018, from 7.9% for the six months ended June 30, 2017. This increase in operating margin percentage was primarily driven by the benefit of lower Selling and administrative expenses as a percentage of Net sales. This was partially offset by product margin compression due to increased hardware sales.

Small Business segment income from operations was $47 million for the six months ended June 30, 2018, an increase of $11 million, or 30.3%, compared to $36 million for the six months ended June 30, 2017. Small business segment income from operations increased primarily due to higher gross profit dollars. Small Business segment operating margin percentage increased 120 basis points to 7.1% for the six months ended June 30, 2018, from 5.9% for the six months ended June 30, 2017. This increase in operating margin percentage was primarily driven by higher product margin and the benefit of lower sales payroll expenses and intangible asset amortization expenses as a percentage of Net sales.

Public segment income from operations was $185 million for the six months ended June 30, 2018, an increase of $20 million, or 11.7%, compared to $165 million for the six months ended June 30, 2017. Public segment income from operations increased primarily due to higher Gross profit dollars driven by improved product margin. Public segment operating margin percentage increased 50 basis points to 6.4% for the six months ended June 30, 2018, from 5.9% for the six months ended June 30, 2017. This increase in operating margin percentage was primarily driven by a higher product margin and the benefit of lower sales payroll expenses as a percentage of Net sales.

Other income from operations was $42 million for the six months ended June 30, 2018, an increase of $17 million, or 65.1%, compared to $25 million for the six months ended June 30, 2017. Other income from operations increased primarily due to higher sales volumes and Gross profit as we continue to take share in the local markets, and favorable foreign exchange. Other operating margin percentage increased 90 basis points to 4.3% for the six months ended June 30, 2018, from 3.4% for the six months ended June 30, 2017. This increase was primarily due to lower sales payroll expenses and lower intangible asset amortization as a percentage of Net sales. Also contributing to the increased operating margin percentage was the non-recurrence of integration expenses in the current year.

Net loss on extinguishments of long-term debt

During the six months ended June 30, 2017, we incurred a net loss on extinguishment of long-term debt of $57 million. For information regarding our debt, see Note 6 (Long-Term Debt) to the accompanying Consolidated Financial Statements.

Net loss on extinguishments of long-term debt for the six months ended June 30, 2017 are as follows:



Month of Extinguishment	Debt Instrument	(in millions)
Month of Extinguishment	Debt Instrument	Amount Extinguished		Loss Recognized
February 2017	Senior Secured Term Loan Facility	$	1,483.0	$	(13.7	)

March 2017	Senior secured asset-based revolving credit facility	—		(1.2		)
	Total Loss Recognized			$	(57.4	)


(1)	We repaid all of the remaining aggregate principal amount outstanding. The loss recognized represents the difference between the aggregate principal amount and the net carrying amount of the purchased debt, adjusted for the remaining unamortized deferred financing fees and premium.

Income tax expense

Income tax expense was $96 million for the six months ended June 30, 2018, compared to $71 million for the same period of the prior year. The effective income tax rate, expressed by calculating the income tax expense as a percentage of Income before income taxes, was 24.1% for the six months ended June 30, 2018 and differed from the US federal statutory rate of 21.0% primarily due to state income taxes partially offset by excess tax benefits on equity-based compensation. The effective tax rate for the same period of the prior year was 26.2% and differed from the US federal statutory rate primarily due to excess tax benefits on equity-based compensation.

The lower effective tax rate for the six months ended June 30, 2018 as compared to the same period of the prior year was primarily attributable to the reduction in the US federal statutory rate, partially offset by lower excess tax benefits on equity-based compensation and a higher effective net state income tax rate primarily due to the reduced US federal benefit.

Seasonality

While we have not historically experienced significant seasonality throughout the year, sales in our Corporate segment, which primarily serves US private sector business customers with more than 250 employees, are typically higher in the fourth quarter than in other quarters due to customers spending their remaining technology budget dollars at the end of the year. Additionally, sales in our Public segment have historically been higher in the third quarter than in other quarters primarily due to the buying patterns of the federal government and education customers.

Liquidity and Capital Resources

Overview

We finance our operations and capital expenditures with internally generated cash from operations. As of June 30, 2018, we also have $1.1 billion of availability for borrowings under our senior secured asset-based revolving credit facility and an additional £40 million ($53 million at June 30, 2018) under the CDW UK revolving credit facility. Our liquidity and borrowing plans are established to align with our financial and strategic planning processes and ensure we have the necessary funding to meet our operating commitments, which primarily include the purchase of inventory, payroll and general expenses. We also take into consideration our overall capital allocation strategy, which includes investment for future growth, dividend payments, acquisitions and share repurchases. We believe we have adequate sources of liquidity and funding available for at least the next year; however, there are a number of factors that may negatively impact our available sources of funds. The amount of cash generated from operations will be dependent upon factors such as the successful execution of our business plan and general economic conditions.

Share Repurchase Program

During the six months ended June 30, 2018, we repurchased 2.4 million shares of our common stock for $176 million under the previously announced share repurchase program. For more information on our share repurchase program, see Part II, Item 2, Unregistered Sales of Equity Securities and Use of Proceeds.

Dividends

A summary of 2018 dividend activity for our common stock is as follows:



Dividend Amount	Declaration Date	Record Date	Payment Date
$0.21	February 7, 2018	February 26, 2018	March 12, 2018
$0.21	May 2, 2018	May 25, 2018	June 11, 2018

On August 2, 2018, we announced that our Board of Directors declared a quarterly cash dividend of $0.21 per common share. The dividend will be paid on September 10, 2018 to all stockholders of record as of the close of business on August 24, 2018.

The payment of any future dividends will be at the discretion of our Board of Directors and will depend upon our results of operations, financial condition, business prospects, capital requirements, contractual restrictions, any potential indebtedness we may incur, restrictions imposed by applicable law, tax considerations and other factors that our Board of Directors deems relevant. In addition, our ability to pay dividends on our common stock will be limited by restrictions on our ability to pay dividends or make distributions to our stockholders and on the ability of our subsidiaries to pay dividends or make distributions to us, in each case, under the terms of our current and any future agreements governing our indebtedness.

(1)	Amounts for 2017 have been adjusted to reflect the adoption of Topic 606.


(2)	Includes items such as deferred income taxes, depreciation and amortization, equity-based compensation expense and Net loss on extinguishments of long-term debt.


(3)	The change is primarily due to stronger operating results driven by Net sales and Gross profit growth, partially offset by higher sales payroll.


(4)	The change in Accounts receivable is primarily due to the increased sales volume during 2018 compared to 2017, partially offset by higher cash collections during 2018.


(5)	The change in Merchandise inventory is primarily due to higher stocking positions and timing of shipments in 2018 compared to 2017 and lower inventory levels at the end of 2017.


(6)	The change in Accounts payable-trade is primarily due to the timing of inventory purchases.


(7)	The change in Other is primarily due to the timing of collections of the receivables from vendors.

In order to manage our working capital and operating cash needs, we monitor our cash conversion cycle, defined as days of sales outstanding in accounts receivable plus days of supply in inventory minus days of purchases outstanding in accounts payable, based on a rolling three-month average. Components of our cash conversion cycle are as follows:



	June 30,
(in days)	2018		2017⁽¹⁾
Days of sales outstanding ("DSO")⁽²⁾	50		49
Days of supply in inventory ("DIO")⁽³⁾	13		12
Days of purchases outstanding ("DPO")⁽⁴⁾	(46	)	(45	)
Cash conversion cycle	17		16


(1)	Amounts for 2017 have been adjusted to reflect the adoption of Topic 606.


(2)	Represents the rolling three-month average of the balance of Accounts receivable, net at the end of the period, divided by average daily Net sales for the same three-month period. Also incorporates components of other miscellaneous receivables.


(3)	Represents the rolling three-month average of the balance of Merchandise inventory at the end of the period divided by average daily Cost of sales for the same three-month period.


(4)	Represents the rolling three-month average of the combined balance of Accounts payable-trade, excluding cash overdrafts, and Accounts payable-inventory financing at the end of the period divided by average daily Cost of sales for the same three-month period.

The cash conversion cycle increased to 17 days at June 30, 2018 compared to 16 days at June 30, 2017 as DSO, DIO and DPO each increased 1 day compared to June 30, 2017. The increase in DSO was primarily driven by higher Net sales and related Accounts receivable for third-party services such as software as a service and warranties. These sales have an unfavorable impact

Table of Contents

on DSO as the receivable is recognized on the Consolidated Balance Sheet on a gross basis while the corresponding sales amount in the Consolidated Statement of Operations is recorded on a net basis. This also results in a favorable impact on DPO as the payable is recognized on the Consolidated Balance Sheet without a corresponding Cost of sales in the Statement of Operations because the cost paid to the vendor or third-party service provider is recorded as a reduction to Net sales. Additionally, average inventory balances increased due to stocking positions and the timing of shipments to customers in 2018 which led to an unfavorable impact on DIO.

Investing Activities

Net cash used in investing activities decreased by $3 million in the six months ended June 30, 2018 compared to the same period of the prior year. Capital expenditures were $34 million and $37 million for the six months ended June 30, 2018 and 2017, respectively. The decrease in capital expenditures is primarily due to the timing of investments for improvements to our information technology systems.

Financing Activities

Net cash used in financing activities decreased by $189 million in the six months ended June 30, 2018 compared to the same period of the prior year. The decrease was primarily driven by fewer share repurchases during the six months ended June 30, 2018, which resulted in a $183 million decrease in cash used in financing activities. For more information on our share repurchase program, see Part II, Item 2, Unregistered Sales of Equity Securities and Use of Proceeds.

Long-Term Debt and Financing Arrangements

As of June 30, 2018, we had total indebtedness of $3.2 billion, of which $1.5 billion was secured indebtedness. At June 30, 2018, we were in compliance with the covenants under our various credit agreements and indentures. The amount of CDW’s restricted payment capacity under the Senior Secured Term Loan Facility was $1.3 billion at June 30, 2018. The amount of restricted payment capacity for the CDW UK Term Loan was $133 million at June 30, 2018.

For additional details regarding our debt and refinancing activities, refer to Note 6 (Long-Term Debt) to the accompanying Consolidated Financial Statements.

Inventory Financing Agreements

We have entered into agreements with certain financial intermediaries to facilitate the purchase of inventory from various suppliers under certain terms and conditions. These amounts are classified separately as Accounts payable-inventory financing on the Consolidated Balance Sheets. We do not incur any interest expense associated with these agreements as balances are paid when they are due. For further details, see Note 3 (Inventory Financing Agreements) to the accompanying Consolidated Financial Statements.
