BUSINESS
DESCRIPTION OF BUSINESS
Zions Bancorporation (“the Parent”) is a financial holding company organized under the laws of the State of Utah in 1955, and registered under the BHC Act, as amended. The Parent owns and operates a commercial bank with a total of 450 domestic branches at year-end 2015. The Parent and its subsidiaries (collectively “the Company”) provide a full range of banking and related services, primarily in Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Texas, Utah, Washington, and Wyoming. The Company conducts its banking operations through seven separately managed and branded segments, which we sometimes refer to as “affiliates” or by reference to their respective brands. Full-time equivalent (“FTE”) employees totaled 10,200 at December 31, 2015. For further

information about the Company’s industry segments, see “Business Segment Results” on page 39 in MD&A and Note 21 of the Notes to Consolidated Financial Statements. For information about the Company’s foreign operations, see “Foreign Exposure and Operations” on page 47 in MD&A. The “Executive Summary” on page 25 in MD&A provides further information about the Company.
PRODUCTS AND SERVICES
The Company focuses on providing community banking services by continuously strengthening its core business lines of (1) small and medium-sized business and corporate banking; (2) commercial and residential development, construction and term lending; (3) retail banking; (4) treasury cash management and related products and services; (5) residential mortgage servicing and lending; (6) trust and wealth management; (7) limited capital markets activities, including municipal finance advisory and underwriting; and (8) investment activities. It operates primarily through seven locally managed segments that each do business under a different name. Each of these affiliated banking operations has its own chief executive officer and management team.
The Company provides a wide variety of commercial and retail banking and mortgage lending products and services. It also provides a wide range of personal banking services to individuals, including home mortgages, bankcard, other installment loans, home equity lines of credit, checking accounts, savings accounts, certificates of deposit of various types and maturities, trust services, safe deposit facilities, direct deposit, and Internet and mobile banking. In addition, the Company provides services to key market segments through its Women’s Financial, Private Client Services, and Executive Banking Groups. We also offer wealth management services, as well as online and traditional brokerage services through Zions Direct and Amegy Investments.
On June 1, 2015, the Company announced certain efficiency and restructuring initiatives that included, among other things, the merger of seven subsidiary banks into a single national charter, ZB, N.A., which was completed on December 31, 2015. The Company continues to operate using regional brand names according to geographic location.
In addition to these core businesses, the Company has built specialized lines of business in capital markets and public finance, and is a leader in SBA lending. The Company is one of the nation’s largest providers of SBA 7(a) and SBA 504 financing to small businesses. It owns an equity interest in Farmer Mac and is its top originator of secondary market agricultural real estate mortgage loans. The Company provides finance advisory and corporate trust services for municipalities. The Company also provides trust services to individuals in its wealth management business and bond transfer, stock transfer, and escrow services in its corporate trust business, both within and outside of its footprint.
COMPETITION
The Company operates in a highly competitive environment. The Company’s most direct competition for loans and deposits comes from other commercial banks, credit unions, and thrifts, including institutions that do not have a physical presence in our market footprint but solicit via the Internet and other means. In addition, the Company competes with finance companies, mutual funds, insurance companies, brokerage firms, securities dealers, investment banking companies, financial technology and other non-traditional lending and banking companies, and a variety of other types of companies. These companies may have fewer regulatory constraints and some have lower cost structures or tax burdens.
The primary factors in competing for business include convenience of office locations and other delivery methods, range of products offered, the quality of service delivered, and pricing. The Company must compete effectively along all of these dimensions to remain successful.
SUPERVISION AND REGULATION
The banking and financial services business in which we engage is highly regulated. Such regulation is intended, among other things, to improve the stability of banking and financial companies and to protect the interests of customers, including both loan customers and depositors, and taxpayers. These regulations are not, however, generally intended to protect the interests of our shareholders or creditors, and in fact may have the consequence of

6


Table of Contents

reducing returns to our shareholders. This regulatory framework has been materially revised and expanded since the 2008-2009 financial crisis and recession. In particular, the Dodd-Frank Act and regulations promulgated pursuant to it have given financial regulators expanded powers over nearly every aspect of the Company’s business. These include, among other things, new, higher regulatory capital requirements; regulation of dividends and other forms of capital distributions to shareholders through annual stress testing and capital planning processes; heightened liquidity and liquidity stress testing requirements, which include specific definitions of the types of investment securities that qualify as “high quality liquid assets” and which effectively limit the portion of the Company’s balance sheet that can be used to meet the credit needs of its customers; specific limitations on mortgage lending products and practices; specific limits on certain consumer payment fees; and subjecting compensation practices to specific regulatory oversight and restrictions. Individually and collectively, these additional regulations have imposed and will continue to impose higher costs on the Company, and have reduced and may continue to reduce returns earned by shareholders. Some aspects of the Dodd-Frank Act continue to be subject to rulemaking, many of the rules that have been adopted will take effect over several additional years, and many of the rules that have been adopted may be subject to interpretation or clarification, and accordingly, the impact of such regulatory changes cannot be presently determined. The Company is committed to both satisfying heightened regulatory expectations and providing attractive shareholder returns. However, given the still-changing regulatory environment, the results of these efforts cannot yet be known.
Described below are the material elements of some selected laws and regulations applicable to the Company. The descriptions are not intended to be complete and are qualified in their entirety by reference to the full text of the statutes and regulations described. Changes in applicable laws or regulations, and in their application by regulatory agencies, cannot be predicted, but they may have a material effect on the business and results of the Company.
The Parent is a bank holding company and a financial holding company as provided by the BHC Act, as modified by the GLB Act and the Dodd-Frank Act. These and other federal statutes provide the regulatory framework for bank holding companies and financial holding companies, which have as their umbrella regulator the FRB. The supervision of ZB, N.A. and other regulated subsidiaries is conducted by each subsidiary’s primary functional regulator and the laws and regulations administered by those regulators. The GLB Act allows our subsidiary bank to engage in certain financial activities through financial subsidiaries. To qualify for and maintain status as a financial holding company, or to do business through a financial subsidiary, the Parent and its subsidiary bank must satisfy certain ongoing criteria. The Company currently engages in only limited activities for which financial holding company status is required.
ZB, N.A. is subject to the provisions of the National Bank Act or other statutes governing national banks, as well as the rules and regulations of the OCC, the CFPB, and the FDIC. It is also subject to periodic examination and supervision by the OCC and the FDIC. Some of our nonbank subsidiaries are also subject to regulation by the FRB and other federal and state agencies. These regulatory agencies may exert considerable influence over our activities through their supervisory and examination roles. Our brokerage and investment advisory subsidiaries are regulated by the SEC, FINRA and/or state securities regulators.
The Dodd-Frank Act
The recent financial crisis led to numerous new laws in the United States and internationally for financial institutions. The Dodd-Frank Act, which was enacted in July 2010, is one of the most far reaching legislative actions affecting the financial services industry in decades and significantly restructured the financial regulatory regime in the United States.
The Dodd-Frank Act and regulations adopted under the Dodd-Frank Act broadly affect the financial services industry by creating new resolution authorities, requiring ongoing stress testing of our capital and liquidity, mandating higher capital and liquidity requirements, requiring divestiture of certain equity investments, increasing regulation of executive and incentive-based compensation, requiring banks to pay increased fees to regulatory agencies, and requiring numerous other provisions aimed at strengthening the sound operation of the financial services sector. Among other things affecting capital standards, the Dodd-Frank Act provides that:

7


Table of Contents

the requirements applicable to large bank holding companies (those with consolidated assets of greater than $50 billion) be more stringent than those applicable to other financial companies;
standards applicable to bank holding companies be no less stringent than those applied to insured depository institutions; and
bank regulatory agencies implement countercyclical elements in their capital requirements.
Regulations promulgated under the Dodd-Frank Act require us to maintain greater levels of capital and liquid assets than was generally the case before the crisis and limit the forms of capital that we will be able to rely upon for regulatory purposes. In addition, in its supervisory role with respect to our stress testing and capital planning, our ability to deliver returns to our shareholders through dividends and stock repurchases is subject to prior non-objection by the FRB. The stress testing and capital plan process also could substantially reduce our flexibility to respond to market developments and opportunities in such areas as capital raising and acquisitions.
The Dodd-Frank Act’s provisions and related regulations also affect the fees we must pay to regulatory agencies and the pricing of certain products and services, including the following:
The assessment base for federal deposit insurance was changed to consolidated assets less tangible capital instead of the amount of insured deposits.
The federal prohibition on the payment of interest on business transaction accounts was repealed.
The FRB was authorized to issue regulations governing debit card interchange fees.
The Dodd-Frank Act also created the CFPB, which is responsible for promulgating regulations designed to protect consumers’ financial interests and examining large financial institutions for compliance with, and enforcing, those regulations. The Dodd-Frank Act adds prohibitions on unfair, deceptive or abusive acts and practices to the scope of consumer protection regulations overseen and enforced by the CFPB. The CFPB also enacted new regulations that became fully effective January 10, 2014, which require significant changes to residential mortgage origination; these changes include the definition of a “qualified mortgage” and the requirement regarding how a borrower’s “ability to repay” must be determined. The Dodd-Frank Act subjected national banks to the possibility of further regulation by restricting the preemption of state laws by federal laws, which had enabled national banks and their subsidiaries to comply with federal regulatory requirements without complying with various state laws. In addition, the Dodd-Frank Act gives greater power to state attorneys general to pursue legal actions against banking organizations for violations of federal law.
The Dodd-Frank Act contains numerous provisions that limit or place significant burdens and costs on activities traditionally conducted by banking organizations, such as originating and securitizing mortgage loans and other financial assets, arranging and participating in swap and derivative transactions, proprietary trading and investing in private equity and other funds. For the affected activities, these provisions may result in increased compliance and other costs, increased legal risk, and decreased scope of product offerings and earning assets.
The Company is subject to the provisions of the Volcker Rule (“VR”), issued pursuant to the Dodd-Frank Act. As of December 31, 2014, the Company had divested all securities that were not in compliance with the VR, and had sold all but $18 million (amortized cost) of non-compliant investments. Such investments also provide for $7 million of potential capital calls, which the Company expects to fund, as allowed by the VR, if and as the capital calls are made until the investments are sold. These investments are in private equity funds, and are referred to in this document as private equity investments (“PEIs”). The Company continues to pursue the disposition of all non-compliant PEIs. The FRB has granted a blanket extension of the VR compliance date to July 21, 2016. An additional one-year extension by the FRB is expected to further extend the Volcker conformance period for existing investments to July 21, 2017.
The Company and other companies subject to the Dodd-Frank Act are subject to a number of requirements regarding the time, manner and form of compensation given to its key executives and other personnel receiving incentive compensation, which are being imposed through the supervisory process as well as published guidance

Table of Contents

and proposed rules. These requirements generally implement the compensation restrictions imposed by the Dodd-Frank Act and include documentation and governance, deferral, risk balancing, and claw-back requirements.
Some aspects of the Dodd-Frank Act continue to be subject to rulemaking, many of the rules that have been adopted will take effect over several additional years, and many of the rules that have been adopted may be subject to interpretation or clarification, and accordingly, the impact of such regulatory changes cannot be presently determined.
Capital Standards – Basel Framework
The Basel III capital rules, which effectively replaced the Basel I rules, became effective for the Company on January 1, 2015 (subject to phase-in periods for certain of their components and other provisions). In 2013, the FRB, FDIC, and OCC published final rules (the “Basel III capital rules”) establishing a new comprehensive capital framework for U.S. banking organizations. The rules implemented the Basel Committee’s December 2010 framework, commonly referred to as Basel III, for strengthening international capital standards as well as certain provisions of the Dodd-Frank Act. The Basel III capital rules substantially revised the risk-based capital requirements applicable to bank holding companies and depository institutions, including the Company, compared to the Basel I U.S. risk-based capital rules.
The Basel III capital rules define the components of capital and address other issues affecting the numerator in banking institutions’ regulatory capital ratios. The Basel III capital rules also address risk weights and other issues affecting the denominator in banking institutions’ regulatory capital ratios and replaced the risk-weighting approach derived from Basel I capital accords of the Basel Committee, with a more risk-sensitive approach based, in part, on the standardized approach in the Basel Committee’s 2004 Basel II capital accords. The Basel III capital rules also implemented the requirements of Section 939A of the Dodd-Frank Act to remove references to credit ratings from the federal banking agencies’ rules.
The Basel III capital rules, among other things, (i) introduced a new capital measure called “Common Equity Tier 1” (“CET1”), (ii) specified that Tier 1 capital consists of CET1 and “Additional Tier 1 capital” instruments meeting specified requirements, (iii) applied most deductions/adjustments to regulatory capital measures to CET1 and not to the other components of capital, thus potentially requiring higher levels of CET1 in order to meet minimum ratios, and (iv) expanded the scope of the deductions/adjustments from capital as compared to prior regulations.
Under the Basel III capital rules, the minimum capital ratios as of January 1, 2015 were as follows:
4.5% CET1 to risk-weighted assets;
6.0% Tier 1 capital (i.e., CET1 plus Additional Tier 1) to risk-weighted assets;
8.0% Total capital (i.e., Tier 1 plus Tier 2) to risk-weighted assets; and
4.0% Tier 1 capital to average consolidated assets as reported on consolidated financial statements (known as the “leverage ratio”).
When fully phased-in on January 1, 2019, the Basel III capital rules will also require the Company and its subsidiary bank to maintain a 2.5% “capital conservation buffer” designed to absorb losses during periods of economic stress, composed entirely of CET1, on top of the minimum risk-weighted asset ratios, effectively resulting in minimum ratios of (i) CET1 to risk-weighted assets of at least 7.0%, (ii) Tier 1 capital to risk-weighted assets of at least 8.5%, and (iii) Total capital to risk-weighted assets of at least 10.5%. Banking institutions with a ratio of CET1 to risk-weighted assets above the minimum but below the capital conservation buffer will face constraints on dividends, equity repurchases, and compensation based on the amount of the shortfall. The implementation of the capital conservation buffer will begin on January 1, 2016 at the 0.625% level and increase by 0.625% on each subsequent January 1, until it reaches 2.5% on January 1, 2019.
The Basel III capital rules also prescribe a standardized approach for calculating risk-weighted assets that expand the risk-weighting categories from Basel I-derived categories (0%, 20%, 50% and 100%) to a much larger and more risk-sensitive number of categories, depending on the nature of the assets, generally ranging from 0% for U.S. Government and agency securities, to 600% for certain equity exposures, and resulting in higher risk weights for a

9


Table of Contents

variety of asset categories. In addition, the Basel III capital rules provide more advantageous risk weights for derivatives and repurchase-style transactions cleared through a qualifying central counterparty and increase the scope of eligible guarantors and eligible collateral for purposes of credit risk mitigation.
The Basel III capital rules provide for a number of deductions from and adjustments to CET1. These include, for example, the requirement that mortgage servicing rights, deferred tax assets (“DTA”) dependent upon future taxable income, and significant investments in common equity issued by nonconsolidated financial entities be deducted from CET1 to the extent that any one such category exceeds 10% of CET1 or all such categories in the aggregate exceed 15% of CET1. The application of this part of the rule did not result in any deductions from CET1. As a result of the large amount of CDO sales completed in 2014 and 2015, the Company does not expect the application of the Basel III corresponding deduction rules to have an effect on its Basel III regulatory capital ratios, either as phased-in or on a fully phased-in basis.
Under prior Basel I capital standards, the effects of AOCI items included in capital were excluded for purposes of determining regulatory capital and capital ratios. As a “non-advanced approaches banking organization,” we made a one-time permanent election as of January 1, 2015 to continue to exclude these items, as allowed under the Basel III capital rules.
Basel III also requires additional regulatory capital disclosures to be made that are commonly referred to as “Pillar 3” disclosures. These disclosures require the Company to make prescribed regulatory disclosures on a quarterly basis regarding its capital structure adequacy and risk-weighted assets. The Company began publishing these Pillar 3 disclosures in 2015, and such disclosures are available on the Company’s website.
The Company met all capital adequacy requirements under the Basel III capital rules based upon a 2015 phase-in as of December 31, 2015, and believes it would meet all capital adequacy requirements on a fully phased-in basis if such requirements were currently effective.
Capital Plan and Stress Testing
The Company is required by the Dodd-Frank Act to participate in annual stress tests known as the Dodd-Frank Annual Stress Test (“DFAST”) and Federal Reserve’s Comprehensive Capital Analysis and Review (“CCAR”). The Company submitted its 2015 capital plan and stress test results to the FRB on January 5, 2015. In its capital plan, the Company was required to forecast, under a variety of economic scenarios for nine quarters ending the fourth quarter of 2016, its estimated regulatory capital ratios, including its Tier 1 common (“T1C”) ratio associated with the Basel I capital rules, its CET1 ratio under the Basel III capital rules, and its GAAP tangible common equity ratio. On March 11, 2015, we announced that the Federal Reserve notified us that it did not object to the capital actions outlined in our 2015 capital plan. The plan included (1) the increase of the quarterly common dividend to $0.06 per share beginning in the second quarter of 2015; (2) the continued payment of preferred dividends at the current rates; and (3) up to $300 million in total reduction of preferred equity.
The Company’s stress test results were significantly different from those modeled by the FRB, as the FRB estimated that the Company’s minimum Tier 1 Common ratio in the severely adverse scenario was 5.1%, just above the 5.0% minimum. Since the release of the FRB’s modeled results, the Company has undertaken several actions designed in part to improve the Company’s risk profile under the CCAR stress tests. These actions include selling parts of the investment portfolio, extending the duration of the investment portfolio, and limiting growth in certain loan categories which are perceived as risky in the CCAR stress test.
During the second quarter of 2015, we completed our mid-cycle capital stress test as required under DFAST. The results demonstrated that we maintained sufficient capital to withstand a severe economic downturn. Detailed disclosure of the mid-cycle stress test results can be found on the Company’s website. Under the implementing regulations for CCAR, a bank holding company may generally raise and redeem capital, pay dividends, and repurchase stock and take similar capital-related actions only under a capital plan as to which the FRB has not objected.

On February 17, 2014, the Federal Reserve published final rules to implement Section 165, Enhanced Supervision and Prudential Standards for Nonbank Financial Companies Supervised by the Board of Governors and Certain Bank Holding Companies, of the Dodd-Frank Act. The Company believes that it is in compliance with these rules.
Prompt Corrective Action
The Federal Deposit Insurance Corporation Improvement Act (“FDICIA”) requires each federal banking agency to take prompt corrective action to resolve the problems of insured depository institutions, including but not limited to those that fall below one or more prescribed minimum capital ratios. Pursuant to FDICIA, the FDIC promulgated regulations defining the following five categories in which an insured depository institution will be placed, based on the level of its capital ratios: well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. Under the prompt corrective action provisions of FDICIA as modified by the Basel III capital rules, an insured depository institution generally will be classified as well-capitalized if it has a CET1 ratio of at least 6.5%, a Tier 1 capital ratio of at least 8%, a total capital ratio of at least 10% and a Tier 1 leverage ratio of at least 5%, and an insured depository institution generally will be classified as undercapitalized if its CET1 ratio is under 3%, its total risk-based capital ratio is less than 8%, its Tier 1 risk-based capital ratio is less than 6%, or its Tier 1 leverage ratio is less than 4%. An institution that, based upon its capital levels, is classified as “well-capitalized,” “adequately capitalized,” or “undercapitalized,” may be treated as though it were in the next lower capital category if the appropriate federal banking agency, after notice and opportunity for hearing, determines that an unsafe or unsound condition or an unsafe or unsound practice warrants such treatment. At each successive lower capital category, an insured depository institution is subject to more restrictions and prohibitions, including restrictions on growth, restrictions on interest rates paid on deposits, restrictions or prohibitions on payment of dividends and restrictions on the acceptance of brokered deposits. Furthermore, if a bank is classified in one of the undercapitalized categories, it is required to submit a capital restoration plan to the federal bank regulator, and the holding company must guarantee the performance of that plan.
Other Regulations
The Company is subject to a wide range of other requirements and restrictions contained in both the laws of the United States and the states in which its banks and other subsidiaries operate. These regulations include but are not limited to the following:
Requirements that the Parent serve as a source of strength for its subsidiary bank. The FRB has a policy that a bank holding company is expected to act as a source of financial and managerial strength to its subsidiary bank and, under appropriate circumstances, to commit resources to support the subsidiary bank. The Dodd-Frank Act codifies this policy as a statutory requirement.
Limitations on dividends payable by subsidiaries. A significant portion of the Parent’s cash, which is used to pay dividends on our common and preferred stock and to pay principal and interest on our debt obligations, is derived from dividends paid to the Parent by its subsidiary bank. These dividends are subject to various legal and regulatory restrictions. See Note 18 of the Notes to Consolidated Financial Statements.
Limitations on dividends payable to shareholders. The Parent’s ability to pay dividends on both its common and preferred stock may be subject to regulatory restrictions, including the requirement that they be included in a stress test and capital plan to which the FRB has not objected. See discussion under “Liquidity Management Actions” on page 69.
Safety and soundness requirements. Federal and state laws require that our banks be operated in a safe and sound manner. We are subject to additional safety and soundness standards prescribed in the FDICIA, including standards related to internal controls, information systems, internal audit, loan documentation, credit underwriting, interest rate exposure, asset growth and compensation, as well as other operational and management standards deemed appropriate by the federal banking agencies. The safety and soundness requirements give bank regulatory agencies significant latitude in their supervisory authority over us.
Requirements for approval of acquisitions and activities and restrictions on other activities. Prior approval of the FRB is required under the BHC Act for a financial holding company to acquire or hold more than a 5% voting interest in any bank, to acquire substantially all the assets of a bank or to merge with another financial or bank

11


Table of Contents

holding company. The BHC Act also requires approval for certain nonbanking acquisitions, restricts the activities of bank holding companies that are not financial holding companies to banking, managing or controlling banks and other activities that the FRB has determined to be so closely related to banking as to be a proper incident thereto, and restricts the nonbanking activities of a financial holding company to those that are permitted for financial holding companies or that have been determined by the FRB to be financial in nature, incidental to financial activities, or complementary to a financial activity. Laws and regulations governing national banks contain similar provisions concerning acquisitions and activities.
Limitations on the amount of loans to a borrower and its affiliates.
Limitations on transactions with affiliates. The Dodd-Frank Act significantly expanded the coverage and scope of the limitations on affiliate transactions within a banking organization.
Restrictions on the nature and amount of any investments and ability to underwrite certain securities.
Requirements for opening of branches and the acquisition of other financial entities.
Fair lending and truth in lending requirements to provide equal access to credit and to protect consumers in credit transactions.
Broker-dealer and investment advisory regulations. Certain of our subsidiaries are broker-dealers that engage in securities underwriting and other broker-dealer activities. These companies are registered with the SEC and are members of FINRA. Certain other subsidiaries are registered investment advisers under the Investment Advisers Act of 1940, as amended, and as such are supervised by the SEC. They are also subject to various U.S. federal and state laws and regulations. These laws and regulations generally grant supervisory agencies broad administrative powers, including the power to limit or restrict the carrying on of business for failure to comply with such laws.
Provisions of the GLB Act and other federal and state laws dealing with privacy for nonpublic personal information of individual customers.
Community Reinvestment Art (“CRA”) requirements. The CRA requires banks to help serve the credit needs in their communities, including providing credit to low and moderate income individuals. If our bank subsidiary fails to adequately serve its communities, penalties may be imposed including denials of applications to add branches, relocate, add subsidiaries and affiliates, and merge with or purchase other financial institutions.
Anti-money laundering regulations. The Bank Secrecy Act, Title III of the Uniting and Strengthening of America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA Patriot Act”), and other federal laws require financial institutions to assist U.S. Government agencies in detecting and preventing money laundering and other illegal acts by maintaining policies, procedures and controls designed to detect and report money laundering, terrorist financing, and other suspicious activity.
The Parent is subject to the disclosure and regulatory requirements of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, both as administered by the SEC. As a company listed on the NASDAQ Global Select Market, the Parent is subject to NASDAQ listing standards for quoted companies.
The Company is subject to the Sarbanes-Oxley Act of 2002, the Dodd-Frank Act, and other federal and state laws and regulations which address, among other issues, corporate governance, auditing and accounting, executive compensation, and enhanced and timely disclosure of corporate information. NASDAQ has also adopted corporate governance rules, which are intended to allow shareholders and investors to more easily and efficiently monitor the performance of companies and their directors.
The Board of Directors of the Parent has implemented a comprehensive system of corporate governance and risk practices. This system includes policies and guidelines such as Corporate Governance Guidelines, a Code of Business Conduct and Ethics for Employees, a Directors Code of Conduct, a Related Party Transaction Policy, Stock Ownership and Retention Guidelines, a Compensation Clawback Policy, an insider trading policy including provisions prohibiting hedging and placing restrictions on the pledging of company stock by insiders, and charters for the Audit, Risk Oversight, Compensation, and Nominating and Corporate Governance Committees. More information on the Company’s corporate governance practices is available on the Company’s website at www.zionsbancorporation.com. (The Company’s website is not part of this Annual Report on Form 10-K).

Table of Contents

The Company has adopted policies, procedures and controls to address compliance with the requirements of the banking, securities and other laws and regulations described above or otherwise applicable to the Company. The Company intends to make appropriate revisions to reflect any changes required.
Regulators, Congress, state legislatures, and international consultative bodies continue to enact rules, laws, and policies to regulate the financial services industry and public companies and to protect consumers and investors. The nature of these laws and regulations and the effect of such policies on future business and earnings of the Company cannot be predicted.
GOVERNMENT MONETARY POLICIES
The earnings and business of the Company are affected not only by general economic conditions, but also by policies adopted by various governmental authorities. The Company is particularly affected by the monetary policies of the FRB, which affect both short-term and long-term interest rates and the national supply of bank credit.
In view of the changing conditions in the economy and the effect of the FRB’s monetary policies, it is difficult to predict future changes in loan demand, deposit levels and interest rates, or their effect on the business and earnings of the Company. FRB monetary policies have had a significant effect on the operating results of commercial banks in the past and are expected to continue to do so in the future.

ITEM 1A.
RISK FACTORS
The Company’s growth strategy is driven by key factors while adhering to defined risk parameters. The key elements of Zions’ strategy reflect its prudent risk-taking philosophy. The Company generates revenue by taking prudent and appropriately priced risks. These factors are outlined in the Company’s Risk Appetite Framework.
The Company’s Board of Directors has established a Risk Oversight Committee of the Board, approved an Enterprise Risk Management Framework, and appointed an Enterprise Risk Management Committee (“ERMC”) consisting of senior management to oversee and implement the Framework. The Company’s most significant risk exposure has traditionally come from the acceptance of credit risk inherent in prudent extension of credit to relationship customers. In addition to credit risk, these committees also monitor the following risk areas: market and interest rate risks, liquidity risk, strategic/business risk, operational/technology risks, model risk, capital/financial reporting risks, legal/compliance risks (including regulatory risk), and reputational risk as outlined in the Company’s risk taxonomy. Additional governance and oversight includes Board-approved policies and management committees with direct focus on these specific risk categories.
The following list describes several risk factors which are significant to the Company, including but not limited to:
Credit Risk
Credit quality has adversely affected us in the past and may adversely affect us in the future.
Credit risk is one of our most significant risks. If the strength of the U.S. economy in general and the strength of the local economies in which we conduct operations declined, this could result in, among other things, deterioration in credit quality and/or reduced demand for credit, including a resultant adverse effect on the income from our loan portfolio, an increase in charge-offs and an increase in the allowance for loan and lease losses (“ALLL”).
We have concentrations of risk in our loan portfolio, including loans secured by real estate and oil and gas-related lending, which may have unique risk characteristics that may adversely affect our results. Given the current volatility in oil prices and the potential for oil prices to remain low for an extended period of time, Zions Bancorporation’s credit exposure in oil and gas could be adversely impacted. We have heightened our oversight of this credit exposure and have taken proactive steps to effectively manage this book of business.
Concentration or counterparty risk could adversely affect the Company. Concentration risk across our loan and investment portfolios could pose significant additional credit risk to the Company due to exposures which perform in a similar fashion. Counterparty risk could also pose additional credit risk.

13


Table of Contents

We engage in commercial construction and land acquisition and development lending, as well as commercial term lending, primarily in our Western states footprint. The Company, as a whole, has relatively larger concentrations of such lending than many other peer institutions. In addition, we have a concentration in oil and gas-related lending, primarily in Texas at Amegy. Both commercial real estate (“CRE”) and oil and gas lending are subject to specific risks, including volatility and potential significant and prolonged declines in collateral values and activity levels. In addition, our real estate lending is concentrated in the Western states, and values there may behave differently than in other parts of the United States. We may have other unidentified concentrated or correlated risks in our loan portfolio.
Our business is highly correlated to local economic conditions in a specific geographic region of the United States.
As a regional bank holding company, the Company provides a full range of banking and related services through its local management teams and unique brands in Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Texas, Utah, Washington, and Wyoming. Approximately 80% of the Company’s total net interest income for the year ended December 31, 2015, and 77% of total assets as of December 31, 2015 relate to our banking operations in Utah, Texas, and California. This is compared to 82% of the Company’s total net interest income for the year ended December 31, 2014, and 78% of total assets as of December 31, 2014. As a result of this geographic concentration, our financial results depend largely upon economic conditions in these market areas. Accordingly, adverse economic conditions affecting these three states in particular could significantly affect our consolidated operations and financial results. For example, our credit risk could be elevated to the extent that our lending practices in these three states focus on borrowers or groups of borrowers with similar economic characteristics, which are similarly affected by the same adverse economic events. At both December 31, 2015 and December 31, 2014, loan balances associated with our banking operations in Utah, Texas, and California comprised 81% of the Company’s commercial lending portfolio, 75% of the CRE lending portfolio, and 69% of the consumer lending portfolio. Loans originated by our banking operations in Utah, Texas, and California are primarily to borrowers in those respective states, with the exception of the National Real Estate group, which co-originates or purchases primarily owner occupied first CRE loans from financial institutions throughout the country.
We have been and could continue to be negatively affected by adverse economic conditions.
Adverse economic conditions negatively affect the Company’s assets, including its loans and securities portfolios, capital levels, results of operations, and financial condition. The most recent financial crisis resulted in significant regulatory changes that continue to affect the Company. Although economic conditions have improved since the most recent financial crisis, it is possible that economic conditions may weaken or that sluggish economic conditions may continue for a substantial period of time. Economic and fiscal conditions in the United States and other countries may directly or indirectly adversely impact economic and market conditions faced by the Company and its customers. Any sustained weakness or further weakening in economic conditions would adversely affect the Company. The Company has exposure to oil and gas-related companies that are currently experiencing a prolonged period of low energy prices. For more information regarding the Company’s exposure to oil and gas-related companies see “Oil and Gas-Related Exposure” in “Risk Elements” on pages 52-55 of MD&A in this Form 10-K.
Market and Interest Rate Risks
Failure to effectively manage our interest rate risk and prolonged periods of low interest rates could adversely affect us.
Net interest income is the largest component of the Company’s revenue. Interest rate risk is managed by the Asset Liability Management Committee, which is appointed by the Company’s Board of Directors. Failure to effectively manage our interest rate risk could adversely affect the Company. Factors beyond the Company’s control can significantly influence the interest rate environment and increase the Company’s risk. These factors include competitive pricing pressures for our loans and deposits, adverse shifts in the mix of deposits and other funding sources, and volatile market interest rates resulting from general economic conditions and the policies of governmental and regulatory agencies, in particular the FRB.

14


Table of Contents

The Company remains in an “asset-sensitive” interest rate risk position, which means that net interest income would be expected to increase if interest rates increase, and to decline if interest rates decrease. Most recently, the FRB maintained the target range for federal funds rate at 0.25% to 0.50%, and indicated that it will determine the timing and size of future rate adjustments by assessing realized and expected economic conditions relative to the objectives of maximum employment and 2% inflation.
Financial market participants have recently contemplated the possibility of negative interest rates. With the exception of brief money market disruptions in which some U.S. Treasury bills traded at negative rates, the U.S. has not previously experienced a negative rate environment, although other developed economies have had prolonged periods of negative rates. Therefore, there are many unknown factors which could impact the Company in a negative rate environment. The ability to effectively charge customers interest on deposits will be determined largely by competition for deposits, but the Company’s deposit systems may require modification to allow for negative deposit rates. Asset allocation strategies would be reconsidered were the FRB to charge for excess reserves.
Our estimates of our interest rate risk position related to noninterest-bearing demand deposits are dependent on assumptions for which there is little historical experience, and the actual behavior of those deposits in a changing interest rate environment may differ materially from our estimates, which could materially affect our results of operations.
We have experienced a low interest rate environment for the past several years. Our views with respect to, among other things, the degree to which we are “asset-sensitive,” including our interest rate risk position for noninterest-bearing demand deposits, are dependent on modeled projections that rely on assumptions regarding changes in balances of such deposits in a changing interest rate environment. Because there is no modern precedent for the prolonged, extremely low interest rate environment that has prevailed for the last several years, there is little historical experience upon which to base such assumptions. If interest rates continue to increase, our assumptions regarding changes in balances of noninterest-bearing demand deposits and regarding the speed and degree to which other deposits are repriced may prove to be incorrect, and business decisions made in reliance on our modeled projections and underlying assumptions could prove to be unsuccessful. Because noninterest-bearing demand deposits are a significant portion of our deposit base, realized results which are different from our modeled projections and the underlying assumptions could materially affect our results of operations.
Liquidity Risk
We and/or the holders of our securities could be adversely affected by unfavorable rating actions from rating agencies.
Our ability to access the capital markets is important to our overall funding profile. This access is affected by the ratings assigned by rating agencies to us, certain of our affiliates, and particular classes of securities that we and our banking subsidiary issue. The rates that we pay on our securities are also influenced by, among other things, the credit ratings that we, our affiliates, and/or our securities receive from recognized rating agencies. Ratings downgrades to us, our affiliates, or our securities could increase our costs or otherwise have a negative effect on our results of operations or financial condition or the market prices of our securities.
As a regulated entity, we are subject to capital and liquidity requirements that may limit our operations and potential growth.
We are a bank holding company and a financial holding company. As such, we and our subsidiary bank are subject to the comprehensive, consolidated supervision and regulation of the FRB, the OCC and the FDIC, including risk-based and leverage capital ratio requirements, and Basel III liquidity requirements. Capital needs may rise above normal levels when we experience deteriorating earnings and credit quality, and our banking regulators may increase our capital requirements based on general economic conditions and our particular condition, risk profile and growth plans. In addition, we may be required to increase our capital levels even in the absence of actual adverse economic conditions or forecasts as a result of stress testing and capital planning based on hypothetical future adverse economic scenarios. Compliance with the capital requirements, including leverage ratios, may limit operations that require the intensive use of capital and could adversely affect our ability to expand or maintain

15


Table of Contents

present business levels. For a summary of the capital rules to which we are subject, see “Capital Standards – Basel Framework” in “Supervision and Regulation” on page 9 of MD&A in this Form 10-K.
Liquidity regulations, including regulations establishing a minimum Liquidity Coverage Ratio (“LCR”) and requiring monthly liquidity stress testing applicable to the Company may impact profitability.
The Company is subject to liquidity regulations, including a requirement that it conduct monthly liquidity stress tests, that require it maintain a modified LCR of at least 100% effective January 1, 2016. The Company’s calculation of the modified LCR indicates that the Company is in compliance with the requirement. Such stress testing is subject to ongoing model and assumptions changes which could affect results.
In order to meet the requirements of these new regulations, the Company expects to continue to hold a higher portion of its assets in High Quality Liquid Assets (“HQLA”) and a lower portion of its assets in loans than was generally the case prior to such regulation. HQLA generally have lower yields than loans of the type made by the Company.
The Company may not be able to utilize the significant deferred tax asset recorded on its balance sheet.
The Company’s balance sheet includes a significant DTA. The largest components of this asset result from additions to our ALLL for purposes of generally accepted accounting principles in excess of loan losses actually taken for tax purposes. Our ability to continue to record this DTA is dependent on the Company’s ability to realize its value through net operating loss carrybacks or future projected earnings. Loss of part or all of this asset would adversely impact tangible capital. In addition, inclusion of this asset in determining regulatory capital is subject to certain limitations. Currently no DTA are disallowed for regulatory purposes either on a consolidated basis or at the Company’s subsidiary bank.
Strategic/Business Risk
Problems encountered by other financial institutions could adversely affect financial markets generally and have indirect adverse effects on us.
The commercial soundness of many financial institutions may be closely interrelated as a result of credit, trading, clearing or other relationships between the institutions. As a result, concerns about, or a default or threatened default by, one institution could lead to significant market-wide liquidity and credit problems, losses or defaults by other institutions. This is sometimes referred to as “systemic risk” and may adversely affect financial intermediaries, such as clearing agencies, clearing houses, banks, securities firms and exchanges, with which we interact on a daily basis, and therefore could adversely affect us. Information security and vendor management processes are in place to actively identify, manage and monitor actual and potential impacts.
The regulation of incentive compensation under the Dodd-Frank Act may adversely affect our ability to retain our highest performing employees.
The bank regulatory agencies have published guidance and proposed regulations which limit the manner and amount of compensation that banking organizations provide to employees. These regulations and guidance may adversely affect our ability to attract and retain key personnel. If we were to suffer such adverse effects with respect to our employees, our business, financial condition and results of operations could be adversely affected, perhaps materially.
We have made and are continuing to make significant changes to the Company that include, among other things, the combination of certain of our subsidiary companies into a single entity, other organizational restructurings, efficiency initiatives, and replacement or upgrades of certain core technological systems to improve our control environment, operating efficiency, and results of operations. The ultimate success and completion of these changes, and their effect on the Company, may vary significantly from initial planning, which could materially adversely affect the Company.
During 2013, our Board of Directors approved a significant investment by us to replace our loan and deposit systems and to upgrade our accounting systems. The new integrated system for most of our loans and deposits is expected to employ technology that is a significant improvement over our current systems. These initiatives will be completed in phases to allow for appropriate testing and implementation so as to minimize time delays and cost

overruns. In December 2015, the Company consolidated its seven subsidiary banks, a subsidiary trust company, and our service company into a single bank. The Company also decided to make other organizational changes such as the realignment of management responsibilities and the rationalization of support functions, including accounting and risk, and back office operations. Additionally, in June 2015, management announced certain efficiency initiatives to improve operating results and return on equity.
These changes continue to be implemented and some are in their early stages. By their very nature, projections of duration, cost, expected savings, expected efficiencies, and related items are subject to change and significant variability.
We may encounter significant adverse developments in the completion and implementation of these changes. These may include significant time delays, cost overruns, loss of key people, technological problems, processing failures, and other adverse developments. Our ability to attract key employees with appropriate talent to implement these changes may also be challenged. Further, our ability to maintain an adequate control environment may be impacted. Any or all of these issues could result in disruptions to our systems, processes, controls, procedures, and employees, which may adversely impact our customers and our ability to conduct business.
We have plans, policies and procedures designed to prevent or limit the negative effect of these potential adverse developments. However, there can be no assurance that any such adverse developments will not occur or, if they do occur, that they will be adequately remediated. The ultimate effect of any adverse development could damage our reputation, result in a loss of customer business, subject us to additional regulatory scrutiny, or expose us to civil litigation and possible financial liability, any of which could materially affect the Company, including its control environment, operating efficiency, and results of operations.
Operational/Technology Risks
Catastrophic events including, but not limited to, hurricanes, tornadoes, earthquakes, fires, floods, and prolonged drought, may adversely affect the general economy, financial and capital markets, specific industries, and the Company.
The Company has significant operations and a significant customer base in Utah, Texas, California and other regions where natural and other disasters may occur. These regions are known for being vulnerable to natural disasters and other risks, such as hurricanes, tornadoes, earthquakes, fires, floods, and prolonged drought. These types of natural catastrophic events at times have disrupted the local economy, the Company’s business and customers, and have posed physical risks to the Company’s property. In addition, catastrophic events occurring in other regions of the world may have an impact on the Company’s customers and in turn on the Company. Although we have business continuity and disaster recovery programs in place, a significant catastrophic event could materially adversely affect the Company’s operating results.
We could be adversely affected by failure in our internal controls.
A failure in our internal controls could have a significant negative impact not only on our earnings, but also on the perception that customers, regulators and investors may have of the Company. We continue to devote a significant amount of effort, time and resources to improving our controls and ensuring compliance with complex accounting standards and regulations. These efforts also include the management of controls to mitigate operational risks for programs and processes across the Company.
We could be adversely affected by financial technology advancements and other non-traditional lending and banking sources.
The ability to successfully remain competitive is dependent upon our ability to maintain a critical technological capability and identify and develop new, value-added products for existing and future customers. Failure to do so could impede our time to market, reduce customer product accessibility and weaken our competitive position.

Our information systems may experience an interruption or security breach.
We rely heavily on communications and information systems to conduct our business. We, our customers, and other financial institutions with which we interact, are subject to ongoing, continuous attempts to penetrate key systems by individual hackers, organized criminals, and in some cases, state-sponsored organizations. Any failure, interruption or breach in security of these systems could result in failures or disruptions in our customer relationship management, general ledger, deposit, loan and other systems, misappropriation of funds, and theft of proprietary Company or customer data. While we have significant internal resources, policies and procedures designed to prevent or limit the effect of the possible failure, interruption or security breach of our information systems, there can be no assurance that any such failure, interruption or security breach will not occur or, if they do occur, that they will be adequately addressed. The occurrence of any failure, interruption or security breach of our information systems could damage our reputation, result in a loss of customer business, subject us to additional regulatory scrutiny, or expose us to civil litigation and possible financial liability.
Model Risk
We increasingly use models in the management of the Company, and in particular in the required stress testing and capital plan. There is risk that these models are incorrect or inaccurate in various ways, which can cause us to make non-optimal decisions, and this risk causes the Company to hold additional capital as a buffer against that risk.
We attempt to carefully develop, document, back test, and validate the models used in the management of the Company, including, for example, models used in the management of interest rate and liquidity risk, and those used in projecting stress losses in various segments of our credit and securities portfolios, and projecting net revenue under stress. Models are inherently imperfect for a number of reasons, however, and cannot perfectly predict outcomes. Management decisions based in part on such models, therefore, can be suboptimal. In addition, in determining the Company’s capital needs under stress testing, we attempt to specifically quantify the amounts by which model results could be incorrect, and we hold material additional amounts of capital as a buffer against this “model risk.
Capital/Financial Reporting Risks
Stress testing and capital management under the Dodd-Frank Act may limit our ability to increase dividends, repurchase shares of our stock, and access the capital markets.
Under the CCAR, we are required to submit to the FRB each year our capital plan for the applicable planning horizon, along with the results of required stress tests. Each annual capital plan will, among other things, specify our planned capital actions with respect to dividends, preferred stock redemptions, common stock buybacks or issuances, and similar matters and will be subject to the objection or non-objection by the FRB. Moreover, the CCAR process requires us to analyze the pro forma impact on our financial condition of various hypothetical future adverse economic scenarios selected by us and the FRB. We must maintain or raise capital sufficient to meet our risk management and regulatory expectations under such hypothetical scenarios. In connection with the annual CCAR process, we also participate in the Dodd-Frank Act Stress Tests (“DFAST”) on a semi-annual basis. Under DFAST, a standardized strategy for capital actions (dividend payments held constant and other current capital obligations met) is implemented by all participating banks. As required by the Dodd-Frank Act we also submit stress tests to the OCC for our subsidiary bank because it has assets in excess of $10 billion. Under both CCAR and DFAST, the Federal Reserve uses its proprietary models to analyze the Company’s stressed capital position. The severity of the hypothetical scenarios devised by the FRB and OCC and employed in these stress tests is undefined by law or regulation, and is thus subject solely to the discretion of the regulators. The stress testing and capital planning processes may, among other things, require us to increase our capital levels, limit our dividends or other capital distributions to shareholders, modify our business strategies, or decrease our exposure to various asset classes.
Under stress testing and capital management standards implemented by bank regulatory agencies under the Dodd-Frank Act, we may declare dividends, repurchase common stock, redeem preferred stock and debt, access capital markets for certain types of capital, make acquisitions, and enter into similar transactions only if included in a

18


Table of Contents

capital plan to which the FRB has not objected. Any similar transactions not contemplated in our annual capital plan, other than those with an inconsequential impact on actual or projected capital, may require a new stress test and capital plan, which is subject to FRB non-objection. These requirements may significantly limit our ability to respond to and take advantage of market developments.
Economic and other circumstances may require us to raise capital at times or in amounts that are unfavorable to the Company.
The Company and its subsidiary bank must maintain certain risk-based and leverage capital ratios, as required by its banking regulators, which can change depending upon general economic conditions, hypothetical future adverse economic scenarios, and the particular conditions, risk profiles and growth plans of the Company and its subsidiary bank. Compliance with capital requirements may limit the Company’s ability to expand and has required, and may require, the Company or its subsidiaries to raise additional capital, or may require additional capital investment from the Parent. These uncertainties and risks, including those created by legislative and regulatory uncertainties, may increase the Company’s cost of capital and other financing costs.
We could be adversely affected by accounting, financial reporting, and regulatory and compliance risk.
The Company is exposed to accounting, financial reporting, and regulatory/compliance risk. The Company provides to its customers, invests in, and uses for its own capital, funding, and risk management needs, a number of complex financial products and services. Estimates, judgments, and interpretations of complex and changing accounting and regulatory policies are required in order to provide and account for these products and services. Changes in our accounting policies or in accounting standards could materially affect how we report our financial results and conditions. The level of regulatory/compliance oversight has been heightened in recent periods as a result of rapid changes in regulations that affect financial institutions. The administration of some of these regulations and related changes has required the Company to comply before their formal adoption. Therefore, identification, interpretation and implementation of complex and changing accounting standards as well as compliance with regulatory requirements pose an ongoing risk.
Our results of operations depend upon the performance of our subsidiaries.
We are a holding company that conducts substantially all of our operations through our banking subsidiary and other subsidiaries. The Parent receives substantially all of its revenues from dividends from its subsidiaries and primarily from its subsidiary bank. These dividends are a principal source of funds to pay dividends on our common and preferred stock and interest and principal on our debt. We and certain of our subsidiaries experienced periods of unprofitability or reduced profitability during the most recent recession of 2007-2009. The ability of the Company and its subsidiary bank to pay dividends is restricted by regulatory requirements, including profitability and the need to maintain required levels of capital. Lack of profitability or reduced profitability exposes us to the risk that regulators could restrict the ability of our subsidiary bank to pay dividends. It also increases the risk that the Company may have to establish a “valuation allowance” against its net DTA or have that asset disallowed for regulatory capital purposes.
The ability of our subsidiary bank to pay dividends or make other payments to us is also limited by its obligations to maintain sufficient capital and by other general regulatory restrictions on its dividends. If it does not satisfy these regulatory requirements, we may be unable to pay dividends or interest on our indebtedness. The OCC, the primary regulator of our subsidiary bank, has issued policy statements generally requiring insured banks to pay dividends only out of current earnings. In addition, if, in the opinion of the applicable regulatory authority, a bank under its jurisdiction is engaged in or is about to engage in an unsafe or unsound practice, which could include the payment of dividends, such authority may take actions requiring that such bank refrain from the practice. Payment of dividends could also be subject to regulatory limitations if a subsidiary bank were to become “under-capitalized” for purposes of the applicable federal regulatory “prompt corrective action” regulations.
The value of our goodwill may decline in the future.
As of December 31, 2015, the Company had $1 billion of goodwill that was allocated to Amegy, CB&T and Zions Bank. If the fair value of a reporting unit is determined to be less than its carrying value, the Company may have to

Table of Contents

take a charge related to the impairment of its goodwill. Such a charge would occur if the fair value of the Company’s net assets improves at a faster rate than the market value of our reporting units, or if the Company was to experience increases in the book value of a reporting unit in excess of the increase in the fair value of equity of a reporting unit. A significant decline in the Company’s expected future cash flows, a significant adverse change in the business climate, slower economic growth or a significant and sustained decline in the price of the Company’s common stock, any or all of which could be materially impacted by many of the risk factors discussed herein, may necessitate the Company taking charges in the future related to the impairment of its goodwill. Future regulatory actions could also have a material impact on assessments of the appropriateness of the goodwill carrying value. If the Company was to conclude that a future write-down of its goodwill is necessary, it would record the appropriate charge, which could have a material adverse effect on the Company’s results of operations.
Legal/Compliance Risks
The Dodd-Frank Act imposes significant limitations on our business activities and subjects us to increased regulation and additional costs.
The Dodd-Frank Act has material implications for the Company and the entire financial services industry. The Dodd-Frank Act places significant additional regulatory oversight and requirements on financial institutions, particularly those with more than $50 billion of assets, including the Company. In addition, among other things, the Dodd-Frank Act:
affects the levels of capital and liquidity with which the Company must operate and how it plans capital and liquidity levels;
subjects the Company to new and/or higher fees paid to various regulatory entities, including but not limited to deposit insurance fees to the FDIC;
impacts the Company’s ability to invest in certain types of entities or engage in certain activities;
impacts a number of the Company’s business strategies;
requires us to incur the cost of developing substantial heightened risk management policies and infrastructure;
regulates the pricing of certain of our products and services and restricts the revenue that the Company generates from certain businesses;
subjects the Company to capital planning actions, including stress testing or similar actions and timing expectations for capital raising;
subjects the Company to supervision by the CFPB, with very broad rule-making and enforcement authorities;
grants authority to state agencies to enforce state and federal laws against national banks;
subjects the Company to new and different litigation and regulatory enforcement risks; and
limits the manner and amount in which compensation is paid to executive officers and employees generally.
The Company and the entire financial services industry have incurred and will continue to incur substantial personnel, systems, consulting, and other costs in order to comply with new regulations promulgated under the Dodd-Frank Act, particularly with respect to stress testing and risk management. Some aspects of the Dodd-Frank Act continue to be subject to rulemaking, many of the rules that have been adopted will take effect over several additional years, and many of the rules that have been adopted may be subject to interpretation and clarification, and accordingly, the impact of such regulatory changes cannot be presently determined. Individually and collectively, regulations adopted under the Dodd-Frank Act may materially adversely affect the Company’s and the financial services industry’s business, financial condition (including the Company’s ability to compete effectively with less regulated financial services providers), and results of operations.

Table of Contents

Other legislative and regulatory actions taken now or in the future may have a significant adverse effect on our operations and earnings.
In addition to the Dodd-Frank Act described previously, bank regulatory agencies and international regulatory consultative bodies have proposed or are considering new regulations and requirements, some of which may be imposed without formal promulgation. Our deposits are insured by the FDIC up to legal limits and, accordingly, we are subject to FDIC insurance assessments.
There can be no assurance that any or all of these regulatory changes or actions will ultimately be adopted. However, if adopted, some of these proposals could adversely affect the Company by, among other things: impacting after-tax returns earned by financial services firms in general; limiting the Company’s ability to grow; increasing taxes or fees on some of the Company’s funding or activities; limiting the range of products and services that the Company could offer; and requiring the Company to raise capital at inopportune times.
The ultimate impact of these proposals cannot be predicted as it is unclear which, if any, may be adopted.
We could be adversely affected by legal and governmental proceedings.
We are subject to risks associated with legal claims, fines, litigation, and regulatory and other government proceedings. The Company’s exposure to these proceedings has increased and may further increase as a result of stresses on customers, counterparties and others arising from the past or current economic environments, new regulations promulgated under recently adopted statutes, the creation of new examination and enforcement bodies, and increasingly aggressive enforcement and legal actions against banking organizations.
Reputational Risk
The company is presented with various reputational risk issues that could stem from operational, compliance and legal risks.
A Reputational Risk Council was established to monitor, manage and develop strategies to effectively manage reputational risk which includes, but is not limited to, addressing communication logistics, legal and regulatory issues.

EQUITY CAPITAL AND DIVIDENDS
We have 4,400,000 authorized shares of preferred stock without par value and with a liquidation preference of $1,000 per share. As of December 31, 2015, 66,139, 143,750, 171,827, 126,221, 125,224, and 195,152 of preferred shares series A, F, G, H, I, and J respectively, have been issued and are outstanding. In general, preferred shareholders may receive asset distributions before common shareholders; however, preferred shareholders have only limited voting rights generally with respect to certain provisions of the preferred stock, the issuance of senior preferred stock, and the election of directors. Preferred stock dividends reduce earnings available to common shareholders and are paid quarterly or semiannually in arrears. The preferred stock redemption amount is computed at the per share liquidation preference plus any declared but unpaid dividends. All of the outstanding series of preferred stock are registered with the SEC. In addition, Series A, F, G, and H preferred stock are listed and traded on the New York Stock Exchange. See Note 13 of the Notes to Consolidated Financial Statements for further information regarding the Company’s preferred stock.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
MANAGEMENT’S DISCUSSION AND ANALYSIS

EXECUTIVE SUMMARY
Company Overview
Zions Bancorporation (“the Parent”) and its subsidiaries (collectively “the Company,” “Zions,” “we,” “our,” “us”) together comprise a $60 billion financial holding company headquartered in Salt Lake City, Utah. The Company is considered a “systemically important financial institution” under the Dodd-Frank Act.
As of December 31, 2015, the Company was the 23rd largest domestic bank holding company in terms of deposits and is included in the S&P 500 and NASDAQ Financial 100 indices.
At December 31, 2015, the Company had banking operations through 450 domestic branches in eleven Western and Southwestern states. Additionally, the Company currently has, and is further developing, numerous online product offerings to support customer banking preferences in the digital era of banking.
The Company has been awarded numerous “Excellence” awards by Greenwich Associates, having received 31 awards for the 2015 survey; only four U.S. banks have been awarded more than 10 excellence awards since the inception of the survey.
The Company has been awarded numerous “Best Brand Awards” for Small Business and Middle Market Banking in 2015 and 2014. The Company has also been awarded numerous national and several regional “Excellence” awards for Small Business and Middle Market Banking in 2014.
The long term strategy of the Company is driven by four key factors:
We focus our banking business in geographies representing growth markets in the Western United States.
We strive to maintain a local community bank-like approach for customer-facing elements of our business by giving a significant degree of autonomy in product offerings and pricing to our regional management teams. Management believes this provides a meaningful competitive advantage over larger national banks whose loan and deposit products are often homogeneous.
Relative to smaller community banks, we believe the Company generally achieves greater economies of scale and stronger risk management. We believe that scale gives us superior access to capital markets, more robust treasury management and other product capabilities than smaller community banks.
We centralize or oversee centrally many non-customer facing operations, such as risk and capital management, and technology and back office operations.
During 2015, we took significant actions to positively improve the Company’s risk profile, including selling the remaining CDO portfolio, purchasing HQLA securities, reducing long term debt and preferred stock, and reducing our oil and gas-related credit exposure.
In December 2015, the Company consolidated its various banking charters into a single charter in order to simplify the corporate structure and remove associated costs; however, we will continue to emphasize our locally-oriented leadership structure and the power of our strong local brands in each market we serve.
The Company announced in 2015 various initiatives designed to substantially improve profitability and announced in 2013 various initiatives to substantially upgrade its technology platform.
The Company’s various measures of capital, credit quality, and liquidity generally rank within the top quartile of regional bank peers.
Revenues and profits are primarily derived from commercial customers and the Company also emphasizes mortgage banking, wealth management and brokerage services.

Table of Contents

MANAGEMENT’S OVERVIEW OF 2015 PERFORMANCE
The Company reported net earnings applicable to common shareholders for 2015 of $246.6 million or $1.20 per diluted common share compared to $326.6 million or $1.68 per diluted common share for 2014. The decline in net income in 2015 was primarily due to the sale of the Company’s remaining CDO portfolio, $574 million at amortized cost, as the Company sold these non-core assets with asymmetric risk characteristics. While we are encouraged with the 2015 results, net income and returns on capital are still lower than the Company’s objectives. The 2015 results were due to risk reduction actions, major operational initiatives, and operating results.
Major Initiative Announced in 2015
In June 2015, we announced a corporate restructuring, in conjunction with a series of significant changes, designed to substantially improve customer experience (e.g., faster turnaround times), simplify our corporate structure and operations, and drive positive operating leverage. Key elements of the announcement included:
Consolidation of bank charters from seven to one while maintaining local leadership, local product pricing, and local brands. The consolidation of the bank charters occurred on December 31, 2015.
Creation of a Chief Banking Officer position, with responsibility for retail banking, wealth management, and residential mortgage lending.
Consolidation of risk functions and other non-customer facing operations, while emphasizing local credit decision making.
Investment in building technology to meet the demands of a rapidly changing information technology environment.
Financial Performance Targets
Following are the targeted financial performance outcomes of these organizational changes, and associated operational and technological initiatives with some brief comments regarding current performance against these measures:
Achieve an adjusted efficiency ratio in the low 60s by fiscal year 2017, driven by expense and revenue initiatives detailed below; the announced target assumes a slight increase in interest rates. Our efficiency ratio for the second half of 2015 was 69.6%, which met our goal to keep the efficiency ratio less than 70% during the second half of 2015. We are committed to achieving an efficiency ratio of less than 66% in 2016. See “GAAP to Non-GAAP Reconciliations” on page 76 for more information regarding the calculation of the adjusted efficiency ratio.
Increase returns on tangible common equity over the long term to double digit levels. For the fourth quarter of 2015, the tangible return on average tangible common equity was 6.20%, compared to 6.05% for the third quarter 2015, and 4.95% for the fourth quarter of 2014 (see “GAAP to Non-GAAP Reconciliations” on page 76 for more information regarding the calculation of the tangible return on average tangible common equity).
Maintain adjusted noninterest expense below $1.6 billion in 2015 and 2016, although increasing somewhat in 2017; this target excludes those same expense items excluded in arriving at the efficiency ratio (see “GAAP to Non-GAAP Reconciliations” on page 76 for more information regarding the calculation of the efficiency ratio). For 2015 adjusted noninterest expense was $1.58 billion and we are committed to keeping noninterest expense below $1.6 billion in 2016.
Achieve annual gross pretax cost savings of $120 million from operational expense initiatives by fiscal year 2017, which include overhauling technology, consolidating legal charters, and improving operating efficiency across the Company. At year-end 2015 we had achieved more than 50% of the $120 million of cost savings.
Our initiatives are designed to make the Company a more efficient organization that drives positive operating leverage, simplifies the corporate structure and operations, and improves customer experience. The increase in operating leverage is expected to come through increased revenue from growth in loans, deployment of cash to mortgage-backed securities, increased use of interest rate swaps, improvement in core fee income, and disciplined expense management.

If successfully implemented, these initiatives should ultimately produce better revenue and expense trajectories, improve profitability, and drive stronger investor returns.
Risk Management Actions in 2015
During 2015, the Company underwent a significant balance sheet restructuring which contributed to overall changes in its risk profile. The restructuring included the following actions:
We reduced risk by selling the remaining non-core securities CDO portfolio, which is expected to improve the Company’s results under stressful economic conditions.
We improved our earning asset mix with the purchase of HQLA securities of $4.8 billion while maintaining asset sensitivity. This boosted current earnings significantly as compared to the alternative of holding the deposits in cash. This action also should improve the Company’s revenue stability under stressful economic conditions.
We reduced long term debt by $275 million, or 25%, which reduced interest expense, and tendered $176 million of preferred stock which improved net earnings to common shareholders.
We actively managed oil and gas-related credit exposure, resulting in a reduction of approximately $1 billion, or 17%, during 2015.
Areas Experiencing Strength in 2015
Net interest income, which is more than three-quarters of our revenue, improved by $35.3 million as compared to 2014. We reduced long-term debt by $275 million through redemptions at maturity which reduced interest expense by approximately $54.5 million and will continue to benefit net interest income in 2016. Additionally, we increased the investment securities portfolio substantially in 2015, purchasing several billion dollars of government agency securities which resulted in a $24.3 million increase in interest income. This action should improve both the Company’s revenue stability under future stressful economic scenarios and current earnings significantly as compared to the alternative of holding money market investments.
Noninterest income from customer-related fees in the fourth quarter of 2015 increased approximately 4% from the prior year period. This increase was due to increased commercial credit card fees and fees generated on sales of swaps to clients.
Adjusted noninterest expense was held to our articulated goal of less than $1.6 billion (see “GAAP to Non-GAAP Reconciliations” on page 76 for more information regarding the calculation of the efficiency ratio and which expenses are excluded in arriving at adjusted noninterest expense). During the year, we cut consulting expenses by approximately $13 million, or 34%, and took additional steps necessary to meet our aforementioned expense target.
We successfully completed a tender offer for preferred stock, reducing preferred equity by $176 million. Our 2015 capital plan, which runs through the second quarter of 2016, allows for an additional use of up to $120 million of cash for preferred stock redemptions, subject to the generation of retained earnings in approximately that amount subsequent to September 30, 2015.
Tangible book value per common share improved by 5.5% to $27.63 at December 31, 2015, compared to $26.23 at December 31, 2014, due to increased retained earnings and a reduction in AOCI due to CDO sales (see “GAAP to Non-GAAP Reconciliations” on page 76 for more information regarding the calculation of tangible book value per common share).
Areas Experiencing Challenges in 2015
Loan growth – Loans increased on a net basis by $586 million, or 1.5%, compared to December 31, 2014, including increases of $387 million in CRE term loans and $181 million in 1-4 family residential loans. We continued to manage the concentration of construction and land development loans, which declined by $144 million during 2015. We also continued to experience runoff and attrition in our National Real Estate group

owner occupied loan portfolio, which is not expected to continue at the same pace in 2016, in addition to a strategic reduction in our oil and gas-related credit exposure.
Net Interest Margin (“NIM”) – Our NIM declined to 3.19% in 2015 from 3.26% in 2014, which was primarily due to a reduction in FDIC-supported loan income as that portfolio continues to wind down, competitive pricing pressure, and improvement in the underlying quality of our borrowers’ financial condition. Nevertheless, our NIM continued to remain reasonably strong relative to other peer banks.
Energy credit quality – The overall credit quality of our loan portfolio remained strong, but, as expected, the credit quality of our oil and gas-related portfolio deteriorated. At December 31, 2015, approximately $66.2 million, or 2.5%, of the oil and gas-related loan balances were nonaccruing, compared to approximately $16.6 million, or 0.5% at December 31, 2014. As part of our risk management efforts, we reduced our total oil and gas-related credit exposure to $4.8 billion, a reduction of approximately $1 billion, or 17%, during 2015.
Areas of Focus for 2016
In 2016, we are focused on improving Company profitability and returns on equity with initiatives across the enterprise. Major areas of emphasis include:
Business activities:
Stabilize and improve NIM by continuing to incrementally deploy the Company’s excess cash into higher-yielding, short-to-medium duration HQLA, which was begun in the latter half of 2014.
Act on our commitment to achieve an efficiency ratio of less than 66% and hold adjusted noninterest expense below $1.6 billion in 2016 through expense management discipline.
Focus on revenue growth opportunities by continuing to:
emphasize loan growth, particularly through continued strong business lending and additional growth in residential mortgage lending; and
further increase fee income.
Additional improvements in the capital structure:
Reduce the percentage of preferred equity and possibly further reduce debt;
Increase the return on- and of-capital to shareholders.
Credit:
Maintain strong levels of asset quality. We expect oil and gas loans to experience some further deterioration, although losses are currently expected to be manageable; however, we expect credit quality metrics in other segments of the loan portfolio to remain relatively stable.
Operations:
Accelerate positive operating leverage from:
further investment and implementation in previously announced major upgrades to the Company’s systems; and
streamlining and simplifying operations as a result of the efficiency initiatives and charter consolidation.

RESULTS OF OPERATIONS
Net Interest Income, Margin and Interest Rate Spreads
Net interest income is the difference between interest earned on interest-earning assets and interest paid on interest-bearing liabilities. Taxable-equivalent net interest income is the largest portion of our revenue. For 2015, taxable-equivalent net interest income was $1,733.2 million, compared to $1,696.2 million and $1,711.9 million, in 2014 and 2013, respectively. The tax rate used for calculating all taxable-equivalent adjustments was 35% for all years presented.
Net interest margin in 2015 vs. 2014
The NIM was 3.19% and 3.26% for 2015 and 2014, respectively. The decrease resulted primarily from lower yields on loans and reduced interest income from FDIC-supported loans. The impact of these items was partially offset by lower yields and balances on our long-term debt and a change in the mix of interest-earning assets as cash held in money market investments was transitioned to term investment securities.
Even though our average loan portfolio was $649 million higher during 2015, compared to 2014, the average interest rate earned on the loan portfolio was 18 bps lower than it was in 2014. The resulting decline in interest income was primarily caused by reduced interest income on loans purchased from the FDIC in 2009, as those acquired portfolios were successfully managed down, and new loans being originated at lower yields than those that prepaid or matured.
The average balance of available-for-sale (“AFS”) securities for 2015 increased by $1.7 billion or 49.2%, compared to 2014, and the average yield in 2015 was 24 bps lower than in 2014. The decline in the average yield and the changes in the average balance are a result of changes in the composition of the AFS portfolio and the yields of the securities sold and purchased. Beginning in the second half of 2014 we started purchasing U.S. agency pass-through

29

securities in order to increase our holdings of HQLA and to alter the mix of our interest-earning assets. These increases were partially offset by CDO sales and paydowns.
Average noninterest-bearing demand deposits provided us with low cost funding and comprised 43.9% of average total deposits for 2015, compared to 42.4% for 2014. Average interest-bearing deposit balances increased by 2.3% in 2015 compared to 2014; additionally, the rate paid declined by 1 bps to 18 bps.
The average balance of long-term debt was $790 million lower for 2015 compared to 2014. The reduced balance was the result of tender offers, early calls and maturities. The average interest rate on long-term debt for 2015 decreased by 8 bps compared to 2014. This is due to the maturity of higher cost long-term debt in the latter part of 2015. On September 15, 2015 and November 16, 2015 respectively, there was $112 million of 6.0% and $124 million of 5.5% subordinated and convertible debt notes that matured. The total effective cost of this debt was approximately 15% during 2015. The higher effective cost for the debt that matured was due to the amortization of debt discount. We continue to look for opportunities to manage down the cost of funds. Refer to the “Liquidity Risk Management” section beginning on page 68 for more information.
During 2015, most of our cash in excess of that needed to fund earning assets was held in money market investments, primarily deposits with the Federal Reserve Bank. Average money market investments were 15.2% of total interest-earning assets, compared to 15.8% in the prior year.
Net interest margin in 2014 vs. 2013
The NIM was 3.26% and 3.36% for 2014 and 2013, respectively. The decrease resulted primarily from lower yields on loans and AFS investment securities. The impact of these items was partially offset by lower yields and balances on our long-term debt.
Even though our average loan portfolio was $1.4 billion higher during 2014, compared to 2013, the average interest rate earned on those assets was 4.39%, which is 38 bps lower than the comparable prior year rate. This decline in interest income was primarily caused by (1) reduced interest income on loans acquired with FDIC assistance in 2009, as those acquired portfolios were successfully managed down, (2) adjustable rate loans originated in the past resetting to lower rates due to the current repricing index being lower than the rate when the loans were originated, and (3) loans originated at lower rates than the weighted average rate of the existing portfolio. The primary reasons for the narrowing of credit and interest rate spreads was a combination of competitive pricing pressures and improved customer credit, which were the result of a more stable economic environment than compared to prior years; a portion of the narrowing of the spreads may be attributed to the improved fundamental condition of our borrowers, such as stronger earnings and improved leverage ratios.
The average held-to-maturity (“HTM”) securities portfolio was $609 million during 2014, compared to $762 million during the same prior year period. During the fourth quarter of 2013, we reclassified a substantial portion of our CDO securities from HTM to AFS as a result of the impact of the VR. The average yield earned during 2014 on HTM securities was 36 bps higher than the yield in 2013, primarily due to the reclassification of CDO securities into the AFS portfolio during the fourth quarter of 2013 that have a lower yield than the remaining securities in the HTM portfolio.
The average balance of AFS securities for 2014 increased by $365 million, or 11.7%, compared to 2013, and the average yield in 2014 was 15 bps lower than in 2013. The increase in AFS securities was due primarily to purchases of approximately $1 billion par amount of agency pass-through securities. The yield was also impacted by the sale of $913 million amortized cost of our CDO securities during 2014.
Average noninterest-bearing demand deposits provided us with low cost funding and comprised 42.4% of average total deposits for 2014, compared to 39.7% for 2013. Average interest-bearing deposit balances were down 2.5% in 2014 compared to 2013; however, the rate paid declined by 3 bps to 19 bps, thus continuing the difficulty to reduce deposit costs further as these costs approach zero.

During 2014, we reduced long-term debt by $1.2 billion as a result of tender offers, early calls, and redemptions at maturity, including $835 million during the third quarter of 2014. These actions led to a decrease of $463 million, or 20.3%, of our average long-term debt outstanding in 2014 compared to 2013. The average interest rate paid on long-term debt for 2014 decreased by 138 bps compared to 2013. Refer to the “Liquidity Risk Management” section beginning on page 68 for more information.
During 2014, most of our cash in excess of that needed to fund earning assets was invested in money market assets, primarily deposits with the Federal Reserve Bank. Average money market investments were 15.8% of total interest-earning assets, compared to 17.4% in the prior year.

See “Interest Rate and Market Risk Management” on page 63 for further discussion of how we manage the portfolios of interest-earning assets, interest-bearing liabilities, and the associated risk.
Interest rate spreads
The spread on average interest-bearing funds was 2.99% for both 2015 and 2014, and 3.02% for 2013. The spread on average interest-bearing funds for 2015 and 2014 was affected by the same factors that had an impact on the NIM.
We expect the mix of interest-earning assets to continue to change over the next several quarters due to slight-to-moderate loan growth in the commercial and industrial and consumer portfolios, accompanied by somewhat less growth in CRE loans, and partially offset by continued attrition in the oil and gas portfolio. In addition, as discussed below, we are incrementally investing in short-to-medium duration U.S. agency pass-through securities that qualify as HQLA; over time we expect these investments to reduce the proportion of earning assets in money market investments, and increase the proportion of AFS securities. Average yields on the loan portfolio may continue to experience modest downward pressure due to competitive pricing and growth in lower-yielding residential mortgages; however, we expect this pressure to be somewhat less compared to the prior two years. We believe that some of the downward pressure on the NIM will be mitigated by lower interest expense on reduced levels of long-term debt due to maturities that occurred towards the end of 2015. We also believe we can offset some of the pressure on the NIM through loan growth, redeployment of cash held in money market investments to term investment securities, and employment of interest rate swaps designated as cash flow hedges.
We expect to remain “asset-sensitive” (which refers to net interest income increasing as a result of a rising interest rate environment) with regard to interest rate risk. In response to new liquidity and liquidity stress-testing regulations, which elevate, relative to historic levels, the proportion of HQLA we will be required to hold, we decided in the second half of 2014 to begin deploying cash into short-to-medium duration U.S. agency pass-through securities. During 2015, we purchased HQLA securities of $4.8 billion at amortized cost, increasing HQLA securities by $4.0 billion after paydowns and payoffs during the year, and we are continuing these purchases. Over time these purchases are expected to somewhat reduce our asset sensitivity compared to previous periods. Our estimates of the Company’s actual interest rate risk position are highly dependent upon a number of assumptions regarding the repricing behavior of various deposit and loan types in response to changes in both short-term and long-term interest rates, balance sheet composition, and other modeling assumptions, as well as the actions of competitors and customers in response to those changes. In addition, our modeled projections for noninterest-bearing demand deposits, which are a substantial portion of our deposit balances, are particularly reliant on assumptions for which there is little historical experience due to the prolonged period of very low interest rates. Further detail on interest rate risk is discussed in “Interest Rate Risk” on page 63.
The following schedule summarizes the average balances, the amount of interest earned or incurred, and the applicable yields for interest-earning assets and the costs of interest-bearing liabilities that generate taxable-equivalent net interest income.

Schedule 3 analyzes the year-to-year changes in net interest income on a fully taxable-equivalent basis for the years indicated. For purposes of calculating the yields in these schedules, the average loan balances also include the principal amounts of nonaccrual and restructured loans. However, interest received on nonaccrual loans is included in income only to the extent that cash payments have been received and not applied to principal reductions. In addition, interest on restructured loans is generally accrued at reduced rates.

In the analysis of interest changes due to volume and rate, changes due to the volume/rate variance are allocated to volume with the following exceptions: when volume and rate both increase, the variance is allocated proportionately to both volume and rate; when the rate increases and volume decreases, the variance is allocated to rate.

Provisions for Credit Losses
The provision for loan losses is the amount of expense that, in our judgment, is required to maintain the allowance for loan losses at an adequate level based on the inherent risks in the loan portfolio. The provision for unfunded lending commitments is used to maintain the reserve for unfunded lending commitments (“RULC”) at an adequate level based on the inherent risks associated with such commitments. In determining adequate levels of the allowance and reserve, we perform periodic evaluations of our various loan portfolios, the levels of actual charge-

offs, credit trends, and external factors. See Note 6 of the Notes to Consolidated Financial Statements and “Credit Risk Management” on page 50 for more information on how we determine the appropriate level for the ALLL and the RULC.

During the past few years, we have experienced an improvement in credit quality metrics; however, recently we have experienced deterioration in credit quality metrics associated with oil and gas-related loans at Amegy. Overall credit quality metrics for 2015 compared to 2014 deteriorated moderately. Gross loan and lease charge-offs increased to $138.9 million in 2015, compared to $106.2 million in 2014. Additionally, we had gross recoveries of $100.3 million in 2015, compared to $64.0 million in 2014.

Nonperforming assets increased to $357 million at December 31, 2015 from $326 million at December 31, 2014. The ratio of nonperforming assets to loans and leases and other real estate owned (“OREO”) increased to 0.87% at December 31, 2015 from 0.81% at December 31, 2014. Classified loans increased to $1.4 billion at December 31, 2015 from $1.1 billion at December 31, 2014. Approximately 87% of classified loans at December 31, 2015 were current as to principal and interest payments, compared to 83% at December 31, 2014. Classified loans are loans with well-defined credit weaknesses that are risk graded Substandard or Doubtful.

The allowance for loan losses increased by approximately $1.4 million since December 31, 2014, due to deterioration within the oil and gas portfolio, which offset improvements in credit quality metrics outside of the oil and gas portfolio. This resulted in a provision of $40.0 million in 2015, compared to a provision of $(98.1) million for 2014. The negative provision in 2014 was due to the continued improvement in portfolio-specific credit quality metrics and sustained improvement in broader economic and credit quality indicators up to that point. We continue to exercise caution with regard to the appropriate level of the allowance for loan losses, given the state of the economy and the sensitivity of the oil and gas loan portfolio to energy prices. Refer to the “Oil and Gas-Related Exposure” section on page 52 for more information.

During 2015, we recorded a $(6.2) million provision for unfunded lending commitments compared to $(8.6) million in 2014. The negative provision recognized in 2015 is primarily due to the funding of one large impaired letter of credit, partially offset by deterioration in the oil and gas-related portfolio. The negative provision recognized in 2014 was primarily due to significant improvement in portfolio-specific credit quality metrics, sustained improvement in broader economic and credit quality indicators, and changes in the portfolio mix. From quarter to quarter, the provision for unfunded lending commitments may be subject to sizable fluctuations due to changes in the timing and volume of loan commitments, originations, funding, and changes in credit quality.
Noninterest Income
Noninterest income represents revenues we earn for products and services that have no associated interest rate or yield. For 2015, noninterest income was $377.1 million compared to $508.6 million in 2014 and $337.4 million in 2013.

Other service charges, commissions and fees, which are comprised of ATM fees, insurance commissions, bankcard merchant fees, debit and credit card interchange fees, cash management fees, lending commitment fees, syndication and servicing fees, and other miscellaneous fees, increased by $12.8 million compared to 2014. The increase was primarily a result of higher interchange fees and fees generated on sales of swaps to clients, partially offset by a decline in loan fees. In 2014, other service charges commissions and fees increased by $10.0 million compared to 2013. Most of the increase can be attributed to higher interchange fees, which increased by approximately $13 million in 2014, primarily due to increased numbers of commercial card customers and increased usage of those cards. This was offset by a decrease of approximately $3 million in exchange and other fees.

Loan sales and servicing income remained relatively flat, increasing only 5.5%, in 2015 compared to 2014. Income from loan sales and servicing remained low in 2015 and 2014 compared to prior periods as the Company is continuing to retain more of its loan production than in previous years. Loan sales and servicing income decreased by $9.0 million in 2014 compared to 2013. The decrease was mainly caused by decreased income from residential mortgage loan sales in 2014, compared to 2013. In 2014, the Company and the industry experienced a reduction in the volume of new residential loan originations primarily for refinanced mortgages. In response, we decided to retain more newly-originated loans on our balance sheet rather than sell them, in order to fund them using some of our excess balance sheet liquidity to improve net interest income.

Capital markets and foreign exchange income includes trading income, public finance fees, foreign exchange income, and other capital market related fees. In 2015, capital markets and foreign exchange income increased by $3.1 million due to an increase of approximately $3.4 million in bond origination fees. In 2014, capital markets and foreign exchange income decreased by $5.5 million due primarily to a $1.8 million decrease in trading income and a $1.7 million decrease in bond origination fees from clients due to lower levels of financing activity.

Dividends and other investment income declined by $13.5 million in 2015 compared to 2014 primarily as a result of write-downs on certain PEIs. In 2014 dividends and other investment income declined by $2.5 million compared to 2013.

Fair value and nonhedge derivative loss improved by $11.3 million in 2015 compared to 2014 primarily as a result of not having any fees associated with the total return swap (“TRS”) that was terminated effective April 28, 2014 and an improvement in the derivative fair value credit adjustments. In 2014, fair value and nonhedge derivative loss

36


Table of Contents

improved by $6.8 million compared to 2013 primarily as a result of the termination of the TRS, partially offset by losses on derivative fair value credit adjustments.

During 2015 we recorded $11.9 million of equity securities gains, compared to $13.5 million in 2014 and $8.5 million in 2013. The decrease in 2015 was primarily a result of decreased income from our non-SBIC investments, partially offset by an increase in gains related to our SBIC investments. The increase in 2014 was driven by unrealized gains related to appreciation of our SBIC equity investments.

In 2015 we recorded a fixed income securities loss of $138.7 million compared to a gain of $10.4 million in 2014. During the second quarter of 2015, we sold the remaining portfolio of our CDO securities, or $574 million at amortized cost, and realized net losses of approximately $137 million. The fixed income securities gain of $10.4 million in 2014 was primarily from paydowns and payoffs of the CDO securities.

Other noninterest income increased by $3.2 million in 2015 compared to 2014 primarily as a result from the gain on sale of a branch in California. Other noninterest income decreased by $10.0 million in 2014, primarily due to gains in 2013 related to certain loans, which had been purchased from failed banks covered by FDIC loss-sharing agreements, as well as gains from branch deposit and asset sales.

Noninterest Expense
Noninterest expense decreased by 3.9% to $1,600.5 million in 2015, compared to $1,665.3 million in 2014. In 2014 we redeemed considerable amounts of our long-term debt and incurred debt extinguishment costs that were significantly higher than those incurred during 2015. Other noninterest expense also decreased by approximately $39.5 million in 2015 primarily as a result of reductions in write-downs of the FDIC indemnification asset. Fees related to professional and legal services declined by $15.6 million in 2015 due to a decline in consulting fees. These decreases in expense were partially offset by a $16.3 million, or 1.7%, increase in salaries and employee benefits in 2015 as a result of an increase in employee base salaries.

Salaries and employee benefits increased by $16.3 million, or 1.7%, in 2015 compared to 2014. The increase in base salaries resulted, in part, from increased headcount related to our major systems projects and build-out of our enterprise risk management and stress testing functions, partially offset by reductions elsewhere. Staff involved in those projects tend to be in more highly compensated roles than positions in which reductions occurred. Our

headcount decreased from 10,462 FTE employees to 10,200 as of December 31, 2015. During 2015, we incurred severance costs of approximately $11 million compared to approximately $9 million in 2014. Salaries and employee benefits increased by 4.8% in 2014 compared to 2013 for similar reasons to those in 2015.

Furniture, equipment and software expense increased by $7.9 million in 2015, compared to 2014. The increase was primarily due to an increase in amortization of purchased software and an increase in our maintenance agreements as a result of our continued investment in the business. Furniture, equipment and software expense increased by $8.7 million in 2014, compared to 2013. The increase was due to an increase in our maintenance agreements, added licenses, and contract renewals for a variety of vendors.

Professional and legal services decreased in 2015 by $15.6 million, or 23.6%, from 2014. The decrease was due to a decline in consulting fees primarily related to our CCAR submission. In 2014, fees related to professional and legal services declined by $2.0 million, or 2.9%, due a decline in legal fees, partially offset by an increase in consulting fees.

FDIC premiums increased by $2.2 million, or 6.8%, in 2015 compared to 2014. FDIC premiums decreased in 2014 by $5.8 million, or 15.3%, from 2013. Most of the decrease in 2014 was due to reduced assessment rates resulting from improved credit quality of our loan portfolio and improved capital adequacy.

The FDIC has proposed a change in deposit insurance assessments that implements a Dodd-Frank Act provision requiring banks with over $10 billion in assets to be responsible for recapitalizing the FDIC insurance fund to 1.35% of insured deposits by the end of 2018, after it reaches a 1.15% reserve ratio. If the rule is finalized, it may go into effect in the first half of 2016, and is expected to increase our FDIC assessment by approximately $5-$10 million per year.

In both 2015 and 2014, we reduced long-term debt through tender offers, early calls, and maturities. The tender offers in 2014 resulted in debt extinguishment cost of $44.4 million, compared to $2.5 million in 2015. In 2013, we incurred $120.2 million of debt extinguishment cost due the extinguishment of several long-term debt instruments. For more information, see Note 12 of the Notes to the Consolidated Financial Statements.

Other noninterest expense decreased by $39.5 million in 2015, compared to 2014, and by $19.2 million in 2014, compared to 2013. The decline is primarily the result of decreased write-downs of the FDIC indemnification asset and an increased amount of insurance recoveries. The balance of FDIC-supported loans declined significantly in 2014.

In 2015, we held adjusted noninterest expense below $1.6 billion and plan to do the same in 2016, with a slight increase to noninterest expense in 2017. The expense items that we exclude from the targeted noninterest expense of

Table of Contents

$1.6 billion are the same as those excluded in arriving at the efficiency ratio (see “GAAP to Non-GAAP Reconciliations” on page 76 for more information regarding the calculation of the efficiency ratio).

Income Taxes
Income tax expense was $142.4 million in 2015, $222.9 million in 2014, and $142.9 million in 2013. Our effective income tax rates, including the effects of noncontrolling interests, were 31.5% in 2015, 35.9% in 2014, and 35.1% in 2013. The tax expense rates for all tax years were reduced by nontaxable municipal interest income and nontaxable income from certain bank-owned life insurance. The rate reductions in 2014 were offset by the reduction in the amount of tax credits generated and the inclusion of approximately $3 million of tax-related interest expense in income tax expense on the financial statements. The interest paid related to various notices and to the closure of various federal and state audits. Further, the tax rate in 2015 decreased significantly as a result of the Company’s investments in alternative energy and technology initiatives.

We had a net DTA balance of approximately $203 million at December 31, 2015, compared to $224 million at December 31, 2014. The decrease in the net DTA resulted primarily from items related to loan charge-offs in excess of loan loss provisions and fair value adjustments on security sales. The net decrease in DTA was partially offset by a decrease in the deferred tax liabilities related to the debt exchange from 2009.

We did not record any additional valuation allowance for GAAP purposes as of December 31, 2015. See Note 14 of the Notes to Consolidated Financial Statements and “Critical Accounting Policies and Significant Estimates” on page 80 for additional information.

Preferred Stock Dividends and Redemption
In 2015, we incurred preferred stock dividends of $62.9 million, a decrease of $9.0 million from 2014. In 2014, we incurred preferred stock dividends of $71.9 million, a decrease of $23.6 million from 2013. In November, 2015, we redeemed $176 million of Series I preferred stock pursuant to a cash tender offer announced in October 2015. Assuming no further tender offers, the preferred dividends for 2016 are expected to be $11.7 million in the first and third quarters and $15.1 million in the second and fourth quarters, respectively. However, the Company’s 2015 capital plan, which runs through the second quarter of 2016, allows for an additional use of up to $120 million of cash for preferred stock redemptions subject to retained earnings levels. See further details in Note 13 of the Notes to Consolidated Financial Statements.

BUSINESS SEGMENT RESULTS
Following the close of business on December 31, 2015, we completed the merger of our subsidiary banks with and into Zions First National Bank. Subsequently, Zions First National Bank changed its legal name to ZB, National Association. We continue to manage our banking operations under our existing brand names and business segments, including Zions Bank, Amegy Bank, California Bank & Trust, National Bank of Arizona, Nevada State Bank, Vectra Bank Colorado, and The Commerce Bank of Washington. As discussed in the “Executive Summary” on page 25, most of the lending and other decisions affecting customers are made at the local level. The accounting policies of the individual segments are the same as those of the Company. We allocate the cost of centrally provided services to the business segments based upon estimated or actual usage of those services. Due to the charter consolidation, we are moving to an internal funds transfer pricing allocation system to report results of operations for business segments. Note 21 of the Notes to Consolidated Financial Statements contains selected information from the respective balance sheets and statements of income for all segments.

During 2015, our banking operations experienced improved financial performance. Common areas of financial performance experienced at various levels of the segments include:
increased loan balances, primarily at CB&T, NBAZ, and Vectra;
improvements in credit quality, which, with the exception of oil and gas-related exposures, resulted in reductions of the ALLL; and
increased growth in customer deposit balances, primarily at CB&T, NSB and Vectra.

Zions Bank
Zions Bank is headquartered in Salt Lake City, Utah, and is primarily responsible for conducting operations in Utah, Idaho, and Wyoming. If it were a separately chartered bank, it would be the 4th largest full-service commercial bank in Utah and the 4th largest in Idaho, as measured by domestic deposits in these states. Zions Bank conducts the largest portion of our Capital Markets operations, which include Zions Direct, Inc., fixed income securities trading, correspondent banking, public finance, and trust and investment advisory services.
Within Zions Bank, the National Real Estate group is a wholesale business that generally sources loans from other community banks across the country. Such loans are generally low loan-to-value owner occupied loans, but also include non-owner occupied CRE term loans.
Zions Bank net income decreased by $71.0 million, or 32.2%, during 2015 primarily as a result of losses on CDO sales and an increase in the provision for loan losses. The loan portfolio increased by $83 million during 2015, which consisted of increases of $269 million in commercial loans and $20 million in consumer loans, partially offset by a decrease of $206 million in CRE loans. The decline in CRE loans was mainly the result of a reduction in the National Real Estate construction and term loan portfolios. Nonperforming lending-related assets increased 31.8% due primarily to increases in nonaccrual loans in the commercial and industrial and commercial owner occupied portfolio. Total deposits at December 31, 2015 were 1.6% higher than at December 31, 2014. The NIM in 2015 decreased to 3.31% from 3.40% in 2014.

Amegy Bank
Amegy Bank is headquartered in Houston, Texas. If it were a separately chartered bank, it would be the 9th largest full-service commercial bank in Texas as measured by domestic deposits in the state.

41


Table of Contents

Amegy’s net income decreased by $48.4 million, or 51.9%, in 2015. The decline in net income is mainly due to a $59.1 million increase in the provision for loan losses, primarily for its oil and gas-related loans. See Schedule 16 and discussion of our “Oil and Gas-Related Exposure” on page 53 for more information. Despite the decline in the oil and gas-related portfolio, Amegy has been able to achieve marginal loan portfolio growth, resulting in a $38 million increase from the prior year. During 2015, commercial loans decreased by $572 million, and CRE loans and consumer loans increased by $307 million, and $303 million, respectively. As a result of the oil and gas-related exposure, the credit quality of Amegy’s loan portfolio declined during 2015, and the ratio of allowance for loan losses to net loans and leases increased to 2.20% at December 31, 2015 from 1.53% a year earlier. During 2015, nonperforming lending-related assets increased by 46.8%. Deposits increased by 1.2% from 2014 to 2015. The NIM for Amegy in 2015 increased to 3.16% from 3.12% in 2014, primarily due to recoveries of previously charged-off commercial loans.

California Bank & Trust
California Bank & Trust is headquartered in San Diego, California. If it were a separately chartered bank, it would be the 16th largest full-service commercial bank in California as measured by domestic deposits. Its core business is built on relationship banking by providing commercial, real estate and consumer lending, depository services, international banking, cash management, and community development services.
CB&T’s net income increased by $4.9 million, or 4.8%, in 2015 due to an increase in noninterest income and a decrease in noninterest expense. CB&Ts loan portfolio increased by $302 million in 2015 from the prior year. During 2015, CRE loans grew by $170 million, commercial loans increased by $232 million, while consumer loans declined by $100 million. The credit quality of CB&T’s loan portfolio continues to improve, and the ratio of allowance for loan losses to net loans and leases declined to 0.92% at December 31, 2015 from 1.13% a year earlier. Deposits at December 31, 2015 were $10.5 billion, or 8.4%, higher than at December 31, 2014. CB&Ts NIM for 2015 decreased to 3.62% from 4.05% in 2014.

National Bank of Arizona
National Bank of Arizona is headquartered in Phoenix, Arizona. If it were a separately chartered bank, it would be the 5th largest full-service commercial bank in Arizona as measured by domestic deposits in the state.
NBAZ had net income of $42.0 million in 2015, a $4.5 million or 9.7% decrease from 2014. During 2015, the loan portfolio increased by $159 million, including $199 million in commercial loans, partially offset by decreases of $25 million in CRE loans and $15 million in consumer loans. The credit quality of NBAZ’s loan portfolio continues to improve, and the ratio of allowance for loan losses to net loans and leases declined to 0.97% at December 31, 2015 from 1.07% a year earlier.

Nevada State Bank
Nevada State Bank is headquartered in Las Vegas, Nevada. If it were a separately chartered bank, it would be the 5th largest full-service commercial bank in Nevada as measured by domestic deposits in the state. NSB focuses on serving small and mid-sized businesses as well as retail consumers, with an emphasis on relationship banking.
In 2015, NSB had net income of $31.5 million, compared to $22.3 million in 2014. NSB’s loans declined by $136 million during 2015, including $141 million in commercial loans and $15 million in CRE loans, partially offset by an increase of $20 million in consumer loans. The credit quality of NSB’s loan portfolio improved significantly, and the ratio of allowance for loan losses to net loans and leases was 1.87% and 2.22% at December 31, 2015 and 2014, respectively. During 2015, NSB experienced net loan recoveries of $17.3 million, primarily related to the term loan portfolio, compared to net loan and lease charge-offs of $0.2 million in 2014. Nonperforming lending-related assets declined 9.4% from the prior year. Deposits at December 31, 2014 were 9.3% higher than a year earlier. The NIM for NSB in 2015 decreased to 2.78% from 2.95% in 2014.

Vectra Bank Colorado
Vectra Bank Colorado is headquartered in Denver, Colorado. If it were a separately a chartered bank, it would be the 7th largest full-service commercial bank in Colorado as measured by domestic deposits in the state.
In 2015, Vectra’s net income declined to $15.7 million from $21.4 million in 2014 primarily as a result of an increase in the provision related to Vectra’s oil and gas-related credit exposure. During 2015, total loans increased by $148 million, including $78 million in consumer loans, $56 million in commercial loans, and $14 million in CRE loans.

The Commerce Bank of Washington is headquartered in Seattle, Washington. It operates in Washington through a single office under the Commerce Bank of Washington name and in Portland, Oregon, under The Commerce Bank of Oregon name. Its business strategy focuses on serving the financial needs of commercial businesses, including professional services firms. TCBW has been successful in serving the greater Seattle/Puget Sound and Portland regions without requiring extensive investments in a traditional branch network. It has been innovative in effectively utilizing couriers, bank by mail, remote deposit image capture, and other technologies.
TCBW net income for 2015 was $14.2 million compared to $1.0 million in 2014. The loan portfolio decreased by $9 million, including $8 million decrease in commercial loans and $2 million decrease in CRE loans, with $1 million increase in consumer loans.
Nonperforming lending-related assets decreased $5 million, and the ratio of allowance for loan losses decreased from 1.42% to 1.08% in 2015. Deposits at December 31, 2015 were 20.8% higher than a year earlier. The NIM for TCBW decreased from 3.42% in 2014 to 3.09% in 2015.
TCBW’s 2014 results were adversely affected by settlement of a legal matter relating to claims brought against TCBW in connection with a customer and a number of associated investment funds using the “Meridian” brand name as discussed in further detail in Note 17 of the Notes to Consolidated Financial Statements in the 2014 Form 10-K.

Other Segment
Operating components in the “Other” segment, as shown in Notes 21 and 23 of the Notes to Consolidated Financial Statements, relate primarily to the Parent and eliminations of transactions between segments. The major components at the Parent include net interest income, which includes interest expense on other borrowed funds, net impairment losses on investment securities, and losses from the sale of the remaining CDO portfolio.
Significant changes in 2015 compared to 2014 include $45.3 million increase in net interest income, $47.4 million decrease in noninterest expense primarily due to repurchases, tender offers and redemptions of long-term debt, and $88.6 million decrease in noninterest income.

BALANCE SHEET ANALYSIS
Interest-Earning Assets
Interest-earning assets are those assets that have interest rates or yields associated with them. One of our goals is to maintain a high level of interest-earning assets relative to total assets while keeping nonearning assets at a minimum. Interest-earning assets consist of money market investments, securities, loans, and leases.
Schedule 2, which we referred to in our discussion of net interest income, includes the average balances of our interest earning assets, the amount of revenue generated by them, and their respective yields. Another goal is to

43


Table of Contents

maintain a higher-yielding mix of interest-earning assets, such as loans, relative to lower-yielding assets, such as money market investments or securities, while maintaining adequate levels of highly liquid assets. As a result of slower economic growth accompanied by moderate loan demand in previous periods, the Company’s initiative to maintain a higher-yielding mix of interest-earning assets caused us to deploy excess funds into security purchases and redemptions of long term-term debt.
Average interest-earning assets were $54.4 billion in 2015 compared to $52.0 billion in the previous year. Average interest-earning assets as a percentage of total average assets were 93.7% in 2015 and 93.1% in 2014.
Average loans were $40.2 billion in 2015 and $39.5 billion in 2014. Average loans as a percentage of total average assets were 69.2% in 2015 compared to 70.7% in 2014, primarily driven by a change in the mix of interest-earning assets, due to purchases of term investment securities that outpaced loan growth in 2015.
Average money market investments, consisting of interest-bearing deposits and federal funds sold and security resell agreements, increased by 0.5% to $8.3 billion in 2015 compared to $8.2 billion in 2014. Average securities increased by 40.7% from 2014. Average total deposits increased by 5.1% while average total loans increased by 1.6% in 2015 when compared to 2014.

The amortized cost of investment securities at December 31, 2015 increased by 77.0% from the balances at December 31, 2014, primarily due to purchases of agency guaranteed mortgage-backed securities. There were additional increases in agency securities and SBA loan-backed securities. These increases were partially offset by the sale of the remaining bank and insurance trust preferred CDO portfolio during the second quarter of 2015.
The investment securities portfolio includes $376 million of net premium almost exclusively from SBA loan-backed securities and agency guaranteed mortgage-backed securities. Recent purchases of these securities have occurred at a premium to the respective par amount. The amortization of these premiums each quarter is dependent upon borrower prepayment behavior. Premium amortization for 2015 was approximately $51 million, compared to approximately $23 million in 2014, and is included in portfolio yields. The increased premium amortization is due to both an increased amount of agency guaranteed mortgage-backed securities and SBA loan-backed securities and changes in prepayment rates of the underlying loans.
During the first quarter of 2015, we reclassified all of the remaining held-to-maturity CDO securities, or approximately $79 million at amortized cost, to AFS securities. See Note 5 of the Notes to Consolidated Financial Statements for further discussion regarding this reclassification.
As of December 31, 2015, under the GAAP fair value accounting hierarchy, 0.8% of the $7.6 billion fair value of the AFS securities portfolio was valued at Level 1, 99.2% was valued at Level 2, and there were no Level 3 AFS securities as a result of the sale of the remaining CDO securities. At December 31, 2014, 2.7% of the $3.8 billion fair value of AFS securities portfolio was valued at Level 1, 86.8% was valued at Level 2, and 10.5% was valued at Level 3. See Note 20 of the Notes to Consolidated Financial Statements for further discussion of fair value accounting.

Table of Contents

At December 31, 2015, $1 million of loans to one municipality were on nonaccrual. A significant amount of the municipal loan and lease portfolio is secured by real estate and equipment, and approximately 87% of the outstanding credits were originated by Zions Bank, CB&T, Amegy, and Vectra. See Note 6 of the Notes to Consolidated Financial Statements for additional information about the credit quality of these municipal loans.

Growth in municipal exposures came primarily from increases in the municipal AFS securities portfolio consistent with the Company’s initiative to increase securities. AFS securities generally consist of rated securities with investment grade ratings from one or more major credit rating agencies. HTM securities consist of unrated bonds issued by small local government entities. Prior to purchase, the issuers of municipal securities are evaluated by the Company for their creditworthiness, and some of the securities are guaranteed by third parties.
Foreign Exposure and Operations
Our credit exposure to foreign sovereign risks and total foreign credit exposure is not significant. We also do not have significant foreign exposure to derivative counterparties. We have foreign operations as a result of our branch in Grand Cayman, Grand Cayman Islands B.W.I. While deposits in this branch are not subject to FRB reserve requirements, there are no federal or state income tax benefits to the Company or any customers as a result of these operations. Foreign deposits at December 31, 2015 and 2014 were $294 million and $328 million, respectively.

Loans Held for Sale
Loans held for sale, consisting primarily of consumer mortgage and small business loans to be sold in the secondary market, were $150 million at December 31, 2015, compared to $133 million at December 31, 2014. Consumer loans are primarily fixed-rate mortgages that are originated and sold to third parties.

Loan Portfolio
As of December 31, 2015, net loans and leases accounted for 68.1% of total assets compared to 70.0% at the end of 2014. Schedule 11 presents our loans outstanding by type of loan as of the five most recent year-ends. The schedule also includes a maturity profile for the loans that were outstanding as of December 31, 2015. However, while this schedule reflects the contractual maturity and repricing characteristics of these loans, in a small number of cases, we have hedged the repricing characteristics of our variable-rate loans as more fully described in “Interest Rate Risk” on page 63.

As of December 31, 2015, net loans and leases were $40.7 billion, reflecting a 1.5% increase from the prior year. The increase is primarily attributable to new loan originations, as well as a decrease in paydowns of existing loans.
Most of the loan portfolio growth during 2015 occurred in municipal, CRE term, 1-4 family residential, and home equity credit line loans (“HECL”). The impact of these increases was partially offset by declines in commercial owner occupied, and CRE construction loans. The loan portfolio increased primarily at CB&T, NBAZ, and Vectra, while balances declined at NSB.
Of the significant increases within the portfolio, municipal loans increased approximately $155 million, CRE term loans increased $388 million, and 1-4 family residential loans increased $181 million, due in part to an increase in loan production. The increase in loans occurred across the Company’s geographic footprint.
Commercial owner occupied loans declined approximately $202 million due to the runoff and attrition of the National Real Estate portfolio at Zions Bank, which is not expected to continue at the same pace in 2016. The National Real Estate business is a wholesale business that depends upon loan referrals from other community banking institutions. Due to generally soft loan demand nationally, many community banking institutions are retaining, rather than selling, their loan production.
We expect slight-to-moderate overall loan and lease growth during 2016 primarily in consumer and commercial and industrial loans, partially offset by continued attrition from the National Real Estate and oil and gas-related loan portfolios. We also expect to continue to limit construction and land development loan commitment growth for the

Table of Contents

foreseeable future as part of management’s actions to improve the risk profile of the Company and to reduce portfolio concentration risk.
Loans serviced for the benefit of others increased to $3.0 billion during 2015 from $2.7 billion in 2014.

Since 2009, CB&T and NSB have had loss-sharing agreements with the FDIC that provided indemnification for credit losses of acquired loans and foreclosed assets up to specified thresholds. The last of the agreements for commercial loans, which comprised the major portion of the acquired portfolio, expired as of September 30, 2014. The agreements for 1-4 family residential loans will expire in 2019. In previous periods, the FDIC-supported loan balances were presented separately in schedules within MD&A and in other disclosures, and included purchase credit-impaired (“PCI”) loans, as discussed in Note 6 of the Notes to Consolidated Financial Statements. Due to declining balances, for all periods presented herein, the FDIC-supported/PCI loans have been reclassified to their respective loan segments and classes.

Other Noninterest-Bearing Investments
As part of our initiative to consolidate our charters into a single charter, we will have shares in a single FHLB (Des Moines) and we expect to redeem outstanding shares of the other respective FHLBs, most likely in the second quarter of 2016. Our investment balance in Federal Reserve stock is expected to remain relatively stable. Schedule 12 sets forth our other noninterest-bearing investments.

Premises and Equipment
Premises and equipment increased $76 million, or 9.1%, from the prior year primarily due to an increase of $47 million in buildings and $56 million in software, partially offset by an increase in depreciation of $30 million. The capitalized costs associated with buildings were primarily from the development of a new corporate facility for Amegy in Texas. The increase in software was mainly due to the capitalization of eligible costs related to the development of new lending, deposit and reporting systems.
Deposits
Deposits, both interest-bearing and noninterest-bearing, are a primary source of funding for the Company. Average total deposits increased by 5.1% during 2015, with average interest-bearing deposits decreasing by 2.3% and average noninterest-bearing deposits increasing 9.0%. The average interest rate paid for interest-bearing deposits was 1 bp higher in 2015 than in 2014.
Deposits at December 31, 2015, excluding time deposits $100,000 and over and brokered deposits, increased by 5.8%, or $2.7 billion, from December 31, 2014. The increase was mainly due to an increase in noninterest-bearing demand deposits, interest-bearing domestic savings and money market, and foreign deposits, offset by a decrease in time deposits under $100,000.

Demand and savings and money market deposits comprised 95.2% of total deposits at December 31, 2015, compared with 94.3% at December 31, 2014.
During 2015 and 2014, we maintained a relatively low level of brokered deposits with the primary purpose of keeping that funding source available in case of a future need. At December 31, 2015, total deposits included $119 million of brokered deposits compared to $108 million at December 31, 2014.

RISK ELEMENTS
Since risk is inherent in substantially all of our operations, management of risk is an integral part of our operations and is also a key determinant of our overall performance. The Board of Directors has appointed a Risk Oversight Committee (“ROC”) that consists of appointed Board members who oversee the Company’s risk management processes. The ROC meets on a regular basis to monitor and review Enterprise Risk Management (“ERM”) activities. As required by its charter, the ROC performs oversight for various ERM activities and approves ERM policies and activities as detailed in the ROC charter.
Management applies various strategies to reduce the risks to which the Company’s operations are exposed, including credit, interest rate and market, liquidity, and operational risks. These risks are overseen by the various management committees of which the ERMC is the focal point for the monitoring and review of enterprise risk.
Credit Risk Management
Credit risk is the possibility of loss from the failure of a borrower, guarantor, or another obligor to fully perform under the terms of a credit-related contract. Credit risk arises primarily from our lending activities, as well as from off-balance sheet credit instruments.

The Board of Directors, through the ROC, is responsible for approving the overall policies relating to the management of the credit risk of the Company. In addition, the ROC oversees and monitors adherence to key policies and the credit risk appetite which is defined in the Risk Appetite Framework. Additionally, the Board has established the Credit Administration Committee (“CAC”), chaired by the Chief Credit Officer and consisting of members of management, to which it has delegated the responsibility for managing credit risk for the company.

Centralized oversight of credit risk is provided through credit policies, credit administration, and credit examination functions at the Parent. We separate the lending function from the credit administration function, which strengthens control over, and the independent evaluation of, credit activities. Formal loan policies and procedures provide the Company with a framework for consistent underwriting and a basis for sound credit decisions at the local banking affiliate level. In addition, we have a well-defined set of standards for evaluating our loan portfolio, and we utilize a comprehensive loan grading system to determine the risk potential in the portfolio. Furthermore, an independent internal credit examination department periodically conducts examinations of the Company’s lending departments. These examinations are designed to review credit quality, adequacy of documentation, appropriate loan grading administration, and compliance with lending policies. Credit examination reports are submitted to management and to the ROC on a regular basis. New, expanded, or modified products and services, as well as new lines of business, are approved by the New Product Review Committee.

Both the credit policy and the credit examination functions are managed centrally. Emphasis is placed on strong underwriting standards and early detection of potential problem credits in order to develop and implement action plans on a timely basis to mitigate any potential losses.

Our credit risk management strategy includes diversification of our loan portfolio. We attempt to avoid the risk of an undue concentration of credits in a particular collateral type or with an individual customer or counterparty. Generally, our loan portfolio is well diversified; however, due to the nature of our geographical footprint, there are

50


Table of Contents

certain significant concentrations primarily in commercial real estate (“CRE”) and oil and gas-related lending. We have adopted and adhere to concentration limits on various types of CRE lending, particularly construction and land development lending, leveraged lending, municipal lending, and oil and gas-related lending. All of these limits are continually monitored and revised as necessary. The recent growth in construction and land development loan commitments is within the established concentration limits. Our business activity is primarily with customers located within the geographical footprint of our banking affiliates.

The credit quality of our loan portfolio slightly deteriorated during 2015. Nonperforming lending-related assets at December 31, 2015 increased by approximately 9.6% from December 31, 2014. Gross charge-offs for 2015 increased to $139 million from $106 million in 2014. However, net charge-offs decreased to $39 million from $42 million for the same periods.

As displayed in Schedule 13, commercial and industrial loans were the largest category and constituted 32.5% of our loan portfolio at December 31, 2015. Construction and land development loans slightly decreased to 4.5% of total loans at December 31, 2015, compared to 5.0% at December 31, 2014.

Oil and Gas-Related Exposure
Various industries represented in the previous schedule, including mining, quarrying and oil/gas extraction; manufacturing; and transportation and warehousing; contain certain loans we categorized as oil and gas-related. At December 31, 2015 and 2014, we had approximately $4.8 billion and $5.8 billion of total oil and gas-related credit exposure, respectively. The distribution of oil and gas-related loans by customer market segment is shown in Schedule 16.

Because many borrowers operate in multiple businesses, judgment has been applied in characterizing a borrower as oil and gas-related, including a particular segment of oil and gas-related activity, e.g., upstream or downstream.
2 
Calculated as the ratio of annualized net charge-offs from the fourth quarters of 2015 and 2014, respectively, to loan balances at period end 2015 and 2014, respectively.
During 2015, our overall balance of oil and gas-related loans decreased approximately $451 million, or 14.7%, to $2.6 billion, primarily as a result of payoffs and pay-downs; exploration and production loan balances decreased 22.3%, and energy services loan balances declined 20.7%. Unfunded oil and gas-related lending commitments declined by $549 million, or 20.3%. The decline in oil and gas-related credit exposure during 2015 was consistent with expectations, and further attrition over the next several quarters is likely.
As expected, the credit quality of the oil and gas loan portfolio deteriorated during 2015, and will likely continue throughout 2016 due to low energy prices. At December 31, 2015, approximately $66.2 million, or 2.5%, of the oil and gas-related loan balances were nonaccruing, compared to approximately $16.6 million, or 0.5% at December 31, 2014. Approximately 71% of oil and gas-related nonaccruing loans were current as to principal and interest payments at December 31, 2015, up from approximately 62% at December 31, 2014.
Classified oil and gas-related credits increased to $517.5 million at December 31, 2015, from $133.6 million at December 31, 2014. Oil and gas-related loan net charge-offs were $42.5 million for 2015, compared to $8.8 million for 2014. The majority of loan downgrades during 2015 reflected deterioration in the financial condition of oilfield services companies and, to a lesser degree, a small number of downgrades in the upstream portfolio. Further downgrades are likely; however, we currently believe we have established an appropriate reserve for the portfolio. The pattern of a significant increase in graded or classified oil and gas loans as well as the increase in nonaccrual oil and gas loans is generally consistent with prior cycles.
Upstream
Upstream exploration and production loans comprised approximately 31% and 34% of the oil and gas-related loans at December 31, 2015 and December 31, 2014, respectively. Many upstream borrowers have relatively balanced production between oil and gas.

53


Table of Contents

We use disciplined underwriting practices to mitigate the risk associated with upstream lending activities. Upstream loans are made to reserve-based borrowers where approximately 90% of those loans are collateralized by the value of the borrower’s oil and gas reserves. Our oil and gas price deck, the pricing applied to a borrower’s reserves for underwriting purposes, has generally been below the NYMEX strip, i.e., the average of the daily settlement prices of the next 12 months’ futures contracts. Through the use of independent and third party engineers and conservative underwriting, we apply multiple discounts. These discounts often range from 10-40% of the value of the collateral in determining the borrowing base (commitment), and help protect credit quality against significant commodity price declines. Further, reserve-based commitments are subject to a borrowing base redetermination based on then-current energy prices, typically every six months. Generally, we have, at our option, the right to conduct additional redeterminations during the year. Borrowing bases for clients are usually set at 60-70% of available collateral after an adjustment for the discounts described above.
Upstream borrowers generally do not draw the maximum available funding on their lines, which provides the borrower additional liquidity and flexibility. The line utilization rate for upstream borrowers was approximately 57% and 58% at December 31, 2015 and December 31, 2014, respectively. This unused commitment gives us the ability in some cases to reduce the borrowing base commitment through the redetermination process without creating a borrowing base deficiency (where outstanding debt exceeds the new borrowing base). Nevertheless, our loan agreements generally require the borrowers to maintain a certain amount of equity. Therefore, if the loan to collateral value exceeds an acceptable limit, we work with the borrowers to reinstate an acceptable collateral-value threshold. As a result of the fall 2015 redetermination of exploration and production oil and gas-related loan borrowing bases, the borrowing base for total exploration and production commitments, including new commitments, declined approximately 21% since the fall 2014 redetermination.
An additional metric we consider in our underwriting is a borrower’s oil and gas price hedging practices. A considerable portion of our reserve-based borrowers are hedged. As of December 31, 2015, of the upstream borrower’s risk-based estimated oil production and gas production projected in 2016, approximately 61% and 43%, respectively, is hedged based on the latest data provided by the borrowers.
Midstream
Midstream marketing and transportation loans comprised approximately 23% and 19% of the oil and gas-related exposure at December 31, 2015 and December 31, 2014, respectively. Loans in this segment are made to companies that gather, transport, treat and blend oil and natural gas, or that provide services to similar companies. The assets owned by these borrowers, which make this activity possible, are field-level gathering systems (small diameter pipe), pipelines (medium/large diameter pipe), tanks, trucks, rail cars, various water-based vessels, and natural gas treatment plants. Our midstream loans are secured by these assets, unless the borrower is rated investment-grade. A significant portion of our midstream borrowers’ revenues are derived from fee-based contracts, giving them limited exposure to commodity price risk. Since lower oil and gas prices slow the drilling and development of new oil and natural gas, but do not normally result in significant numbers of producing wells being shut in, volumes of oil and gas flowing through midstream systems usually remain relatively stable throughout oil and natural gas price cycles.
Energy Services
Energy services loans, which include oilfield services and energy service manufacturing, comprised approximately 39% and 41% of the oil and gas-related exposure at December 31, 2015 and December 31, 2014, respectively. Energy services loans include borrowers that have a concentration of revenues in the energy industry. However, many of these borrowers provide a broad range of products and services to the energy industry and are not subject to the same volatility as new drilling activities. Many of these borrowers are diversified geographically and service both oil and gas-related drilling and production.
For energy services loans, underwriting criteria require lower leverage to compensate for the cyclical nature of the industry. During the underwriting process, we use sensitivity analysis to consider revenue and cash flow impacts resulting from oil and gas price cycles. Generally, we underwrite energy services loans to withstand a 20-50% decline in cash flows, with higher discounts for those borrowers subject to greater cyclicality.

Risk Management of the Oil and Gas-Related Portfolio
We apply concentration limits and disciplined underwriting to the entire oil and gas-related loan portfolio to limit our risk exposure. Concentration limits on oil and gas-related lending, coupled with adherence to our underwriting standards, served to constrain loan growth during the past several quarters. As an indicator of the diversity in the size of our oil and gas-related portfolio, the average amount of our commitments is approximately $7 million, with approximately 64% of the commitments less than $30 million. Additionally, there are instances where we have commitments to a common sponsor which, when combined, would result in higher commitment levels than $30 million. The portfolio contains only senior loans – no junior or second lien positions; additionally, we cautiously approach making first-lien loans to borrowers that employ excessive leverage through the use of junior lien loans or unsecured layers of debt. Approximately 90% of the total oil and gas-related portfolio is secured by reserves, equipment, real estate, and other collateral, or a combination of collateral types.
We participate as a lender in loans and commitments designated as Shared National Credits (“SNCs”), which generally consist of larger and more diversified borrowers that have better access to capital markets. SNCs are loans or loan commitments of at least $20 million that are shared by three or more federally supervised institutions. The percentage of SNCs is approximately 72% of the upstream portfolio, 72% of the midstream portfolio, and 47% of the energy services portfolio. Our bankers have direct access and contact with the management of these SNC borrowers, and as such, are active participants. In many cases, we provide ancillary banking services to these borrowers, further evidencing this direct relationship.
As a secondary source of support, many of our oil and gas-related borrowers have access to capital markets and private equity sources. Private sponsors tend to be large funds, often with assets under management of more than $1 billion, managed by individuals with a great deal of energy expertise and experience and who have successfully managed energy investments through previous energy price cycles. The investors in the funds are primarily institutional investors, such as large pensions, foundations, trusts, and high net worth family offices.
We expect further downgrades in the oil and gas portfolio, primarily from the oilfield services companies; although, we currently believe we have appropriately reserved for these downgrades. The deterioration of oil and gas-related credits is transpiring consistently with our outlook and expectations from late 2014; although, future energy price volatility may result in further credit deterioration. When establishing the level of the allowance for credit losses(“ACL”), we consider multiple factors, including reduced drilling activity and additional capital raises. During 2015, we increased the ACL on the oil and gas portfolio by approximately $74 million, primarily due to the decline in energy prices, which contributed to an increased provision for loan losses in 2015.

Approximately 24% of the CRE term loans consist of mini-perm loans as of December 31, 2015. For such loans, construction has been completed and the project has stabilized to a level that supports the granting of a mini-perm loan in accordance with our underwriting standards. Mini-perm loans generally have initial maturities of three to seven years. The remaining 76% of CRE loans are term loans with initial maturities generally of 5 to 20 years. The stabilization criteria for a project to qualify for a term loan differ by product type and include criteria related to the cash flow generated by the project, loan-to-value ratio, and occupancy rates.

Approximately $142 million, or 12%, of the commercial construction and land development portfolio at December 31, 2015 consists of acquisition and development loans. Most of these acquisition and development loans are secured by specific retail, apartment, office, or other projects. Underwriting on commercial properties is primarily based on the economic viability of the project with heavy consideration given to the creditworthiness and experience of the sponsor. We generally require that the owner’s equity be injected prior to bank advances. Remargining requirements (required equity infusions upon a decline in value of the collateral) are often included in the loan agreement along with guarantees of the sponsor. Recognizing that debt is paid via cash flow, the projected cash flows of the project are critical in the underwriting because these determine the ultimate value of the property and its ability to service debt. Therefore, in most projects (with the exception of multifamily projects) we look for substantial pre-leasing in our underwriting and we generally require a minimum projected stabilized debt service coverage ratio of 1.20 or higher, depending on the project asset class.

Within the residential construction and development sector, many of the requirements previously mentioned, such as creditworthiness and experience of the developer, up-front injection of the developer’s equity, principal curtailment requirements, and the viability of the project are also important in underwriting a residential development loan. Significant consideration is given to the likely market acceptance of the product, location, strength of the developer, and the ability of the developer to stay within budget. Progress inspections by qualified independent inspectors are routinely performed before disbursements are made.

Real estate appraisals are ordered and validated independent of the loan officer and the borrower, generally by our internal appraisal review function, which is staffed by licensed appraisers. In some cases, reports from automated valuation services are used. Appraisals are ordered from outside appraisers at the inception, renewal or, for CRE loans, upon the occurrence of any event causing a downgrade to an adverse grade (i.e., “criticized” or “classified”). We increase the frequency of obtaining updated appraisals for adversely graded credits when declining market conditions exist.

Advance rates (i.e., loan commitments) will vary based on the viability of the project and the creditworthiness of the sponsor, but our guidelines generally limit advances to 50% for raw land, 65% for land development, 65% for finished commercial lots, 75% for finished residential lots, 80% for pre-sold homes, 75% for models and homes not under contract, and 75% for commercial properties. Exceptions may be granted on a case-by-case basis.

Loan agreements require regular financial information on the project and the sponsor in addition to lease schedules, rent rolls and, on construction projects, independent progress inspection reports. The receipt of this financial information is monitored and calculations are made to determine adherence to the covenants set forth in the loan agreement. Additionally, loan-by-loan reviews of pass-grade loans for all commercial and residential construction and land development loans are performed semiannually at all affiliates except TCBW, which performs such reviews annually.

CRE loans are sometimes modified to increase the likelihood of collecting the maximum possible amount of our investment in the loan. In general, the existence of a guarantee that improves the likelihood of repayment is taken into consideration when analyzing a loan for impairment. If the support of the guarantor is quantifiable and documented, it is included in the potential cash flows and liquidity available for debt repayment and our impairment methodology takes into consideration this repayment source.

Additionally, when we modify or extend a loan, we give consideration to whether the borrower is in financial difficulty, and whether we have granted a concession. In determining if an interest rate concession has been granted, we consider whether the interest rate on the modified loan is equivalent to current market rates for new debt with similar risk characteristics. If the rate in the modification is less than current market rates, it may indicate that a concession was granted and impairment exists. However, if additional collateral is obtained or if a strong guarantor exists who is believed to be able and willing to support the loan on an extended basis, we also consider the nature and amount of the additional collateral and guarantees in the ultimate determination of whether a concession has been granted.

In general, we obtain and consider updated financial information for the guarantor as part of our determination to extend a loan. The quality and frequency of financial reporting collected and analyzed varies depending on the contractual requirements for reporting, the size of the transaction, and the strength of the guarantor.

Complete underwriting of the guarantor includes, but is not limited to, an analysis of the guarantor’s current financial statements, leverage, liquidity, global cash flow, global debt service coverage, contingent liabilities, etc. The assessment also includes a qualitative analysis of the guarantor’s willingness to perform in the event of a problem and demonstrated history of performing in similar situations. Additional analysis may include personal financial statements, tax returns, liquidity (brokerage) confirmations, and other reports, as appropriate.

A qualitative assessment is performed on a case-by-case basis to evaluate the guarantor’s experience, performance track record, reputation, performance of other related projects with which we are familiar, and willingness to work with us. We also utilize market information sources, rating, and scoring services in our assessment. This qualitative analysis coupled with a documented quantitative ability to support the loan may result in a higher-quality internal loan grade, which may reduce the level of allowance we estimate. Previous documentation of the guarantor’s financial ability to support the loan is discounted if there is any indication of a lack of willingness by the guarantor to support the loan.

In the event of default, we evaluate the pursuit of any and all appropriate potential sources of repayment, which may come from multiple sources, including the guarantee. A number of factors are considered when deciding whether or not to pursue a guarantor, including, but not limited to, the value and liquidity of other sources of repayment (collateral), the financial strength and liquidity of the guarantor, possible statutory limitations (e.g., single action rule on real estate) and the overall cost of pursuing a guarantee compared to the ultimate amount we may be able to recover. In other instances, the guarantor may voluntarily support a loan without any formal pursuit of remedies.

Due to the oil and gas price volatility, there could be a potential adverse impact on our CRE loan portfolio within Texas. Our largest credit exposures are to the office, multi-family and hospitality sectors in the city of Houston.
Consumer Loans
We have mainly been an originator of first and second mortgages, generally considered to be of prime quality. Historically, our practice has been to sell “conforming” fixed-rate loans to third parties, including Fannie Mae and Freddie Mac, for which we make representations and warranties that the loans meet certain underwriting and collateral documentation standards. It has also been our practice historically to hold variable-rate loans in our portfolio. We actively monitor loan “put-backs” (required repurchases of loans previously sold to Fannie Mae or Freddie Mac due to inadequate documentation or other reasons). Loan put-backs have been minimal over a multiple-year period. We estimate that we do not have any material risk as a result of either our foreclosure practices or loan put-backs and we have not established any reserves related to these items.

We are engaged in HECL lending. At December 31, 2015 and 2014, our HECL portfolio totaled $2.4 billion and $2.3 billion, respectively. Schedule 18 shows the composition of our HECL portfolio by lien status.

As of December 31, 2015, loans representing approximately 2% of the outstanding balance in the HECL portfolio were estimated to have combined loan-to-value ratios (“CLTV”) above 100%. An estimated CLTV ratio is the ratio of our loan plus any prior lien amounts divided by the estimated current collateral value. At origination, underwriting standards for the HECL portfolio generally include a maximum 80% CLTV with high credit scores at origination.

Approximately 95% of our HECL portfolio is still in the draw period, and approximately 31% is scheduled to begin amortizing within the next five years. We regularly analyze the risk of borrower default in the event of a loan becoming fully amortizing and the risk of higher interest rates. The analysis indicates that the risk of loss from this factor is minimal in the current economic environment. The annualized credit losses for the HECL portfolio were (2) bps and 5 bps, for 2015 and 2014, respectively. See Note 6 of the Notes to Consolidated Financial Statements for additional information on the credit quality of this portfolio.

Nonperforming Assets
Nonperforming lending-related assets as a percentage of loans and leases and OREO increased slightly to 0.87% at December 31, 2015, compared with 0.81% at December 31, 2014.

Total nonaccrual loans at December 31, 2015 increased by $43 million from the prior year, primarily due to deterioration in the oil and gas portfolio. Excluding oil and gas-related loans, nonperforming assets have increased in the CRE term loan class, but have declined in the commercial owner occupied and construction and land development loan classes. The largest total decreases in nonaccrual loans occurred at CB&T.

The balance of nonaccrual loans can decrease due to paydowns, charge-offs, and the return of loans to accrual status under certain conditions. If a nonaccrual loan is refinanced or restructured, the new note is immediately placed on nonaccrual. If a restructured loan performs under the new terms for at least a period of six months, the loan can be considered for return to accrual status. See “Restructured Loans” on page 60 for more information. Company policy does not allow for the conversion of nonaccrual construction and land development loans to CRE term loans. See Note 6 of the Notes to Consolidated Financial Statements for more information.

Restructured Loans
Troubled debt restructuring (“TDR”) are loans that have been modified to accommodate a borrower that is experiencing financial difficulties, and for which we have granted a concession that we would not otherwise consider. TDRs declined approximately 13.4% during 2015, primarily due to payments and payoffs. Commercial loans may be modified to provide the borrower more time to complete the project, to achieve a higher lease-up percentage, to sell the property, or for other reasons. Consumer loan TDRs represent loan modifications in which a concession has been granted to the borrower who is unable to refinance the loan with another lender, or who is experiencing economic hardship. Such consumer loan TDRs may include first-lien residential mortgage loans and

home equity loans.

If the restructured loan performs for at least six months according to the modified terms, and an analysis of the customer’s financial condition indicates that we are reasonably assured of repayment of the modified principal and interest, the loan may be returned to accrual status. The borrower’s payment performance prior to and following the restructuring is taken into account to determine whether or not a loan should be returned to accrual status.

In the periods following the calendar year in which a loan was restructured, a loan may no longer be reported as a TDR if it is on accrual, is in compliance with its modified terms, and yields a market rate (as determined and documented at the time of the modification or restructure). Company policy requires that the removal of TDR status be approved at the same management level that approved the upgrading of a loan’s classification. See Note 6 of the Notes to Consolidated Financial Statements for additional information regarding TDRs.

Allowance for Credit Losses
In analyzing the adequacy of the allowance for loan losses, we utilize a comprehensive loan grading system to determine the risk potential in the portfolio and also consider the results of independent internal credit reviews. To determine the adequacy of the allowance, our loan and lease portfolio is broken into segments based on loan type.

The total ALLL remained relatively unchanged during 2015, due to deterioration within the oil and gas portfolio, which was offset by improvements in credit quality metrics outside of the oil and gas portfolio. However, during 2015, we increased the portion of the ALLL related to qualitative and environmental factors to account for the increased risk of loss on loans likely to be affected by the sharp decline in oil prices and more moderate decline in natural gas prices that occurred during the year.
The total ALLL at December 31, 2014 decreased by $141 million compared to December 31, 2013. The decreases in the ALLL reflected improvements in credit quality trends, somewhat improving economic conditions in some of our markets, and reductions in construction and land development loans. During 2014, we decreased the portion of the ALLL related to qualitative and environmental factors to reflect the positive credit quality trends and stabilizing economic conditions.
The RULC represents a reserve for potential losses associated with off-balance sheet commitments and standby letters of credit. The reserve is separately shown in our balance sheet and any related increases or decreases in the reserve are shown separately in the statement of income. The reserve decreased by $6.2 million during 2015, primarily due to the funding of one large impaired letter of credit, partially offset by the proportionally large amount of unfunded commitments in the oil and gas portfolio compared to the rest of the portfolio.
See Note 6 of the Notes to Consolidated Financial Statements for additional information related to the ACL and credit trends experienced in each portfolio segment.

Interest Rate and Market Risk Management
Interest rate and market risk are managed centrally. Interest rate risk is the potential for reduced net interest income and other rate sensitive income resulting from adverse changes in the level of interest rates. Market risk is the potential for loss arising from adverse changes in the fair value of fixed income securities, equity securities, other earning assets, and derivative financial instruments as a result of changes in interest rates or other factors. As a financial institution that engages in transactions involving an array of financial products, we are exposed to both interest rate risk and market risk.

The Company’s Board of Directors is responsible for approving the overall policies relating to the management of the financial risk of the Company, including interest rate and market risk management. In addition, the Board establishes and periodically revises policy limits and reviews limit exceptions reported by management. The Board has established the Asset/Liability Committee (“ALCO”) consisting of members of management, to which it has delegated the responsibility of managing interest rate and market risk for the Company. ALCO is primarily responsible for managing interest rate and market risk.
Interest Rate Risk
Interest rate risk is one of the most significant risks to which we are regularly exposed. In general, our goal in managing interest rate risk is to have net interest income increase in a rising interest rate environment. We refer to this goal as being “asset-sensitive.” This approach is based on our belief that in a rising interest rate environment, the market cost of equity, or implied rate at which future earnings are discounted, would also tend to rise.

Due to the low level of rates, there is limited sensitivity to falling rates at the current time, and we have tended to operate near interest rate risk “triggers” and appetites to be appropriately positioned in light of prevailing market conditions in order to maximize shareholder value. However, if interest rates remain at their current historically low levels, given our asset sensitivity, we would expect the NIM to be under continuing modest pressure assuming a balance sheet that is static in size. Additionally, market participants have recently contemplated the possibility of negative rates in the U.S. markets which would likely have a more negative impact on the NIM. In order to mitigate this pressure we have been deploying cash into short-to-medium duration agency pass-through securities. Additionally, we have increased the use of interest rate swaps designated as cash flow hedges to synthetically convert floating-rate assets to fixed-rate. Over time these actions are expected to somewhat reduce our asset sensitivity compared to previous periods, while improving current earnings.

Interest Rate Risk Measurement
We monitor interest rate risk through the use of two complementary measurement methods: net interest income simulation and Economic Value of Equity at Risk (“EVE”). In the net interest income simulation method, we analyze the expected change in net interest income in response to changes in interest rates. In the EVE method, we measure the expected changes in the fair value of equity in response to changes in interest rates.

Net interest income simulation is an estimate of the total net interest income that would be recognized under different rate environments. Net interest income is measured under several parallel and nonparallel interest rate environments and deposit repricing assumptions, taking into account an estimate of the possible exercise of embedded options within the portfolio (e.g., a borrower’s ability to refinance a loan under a lower rate environment). Our policy contains a trigger for a 10% decline in rate sensitive income as well as a risk capacity of a 13% decline if rates were to immediately rise or fall in parallel by 200 bps. This trigger and risk capacity apply to both the fast and the slow deposit assumptions.

EVE is calculated as the fair value of all assets minus the fair value of liabilities. We measure changes in the dollar amount of EVE for parallel shifts in interest rates. Due to embedded optionality and asymmetric rate risk, changes in EVE can be useful in quantifying risks not apparent for small rate changes. Examples of such risks may include out-of-the-money interest rate caps (or limits) on loans, which have little effect under small rate movements but may become important if large rate changes were to occur, or substantial prepayment deceleration for low rate mortgages in a higher rate environment.

The following schedule presents the formal EVE limits we have adopted. Exceptions to the EVE limits are subject to notification and approval by the ROC. In the normal course of business, we evaluated our limits and made changes to reflect its current balance sheet management objectives. These changes are reflected in the following schedule.

New Interest Rate Risk Model and Comparisons
In the first quarter of 2015, we adopted a new model to estimate the impact to net interest income and to EVE from changes in interest rates. We made the change because the new model is believed to better reflect customer behavior, particularly with regard to dynamic prepayment speeds (i.e., incrementally slower prepayment speeds on mortgages with incrementally higher interest rate changes) and deposit characteristics (i.e., faster deposit product migration to interest-bearing accounts for larger deposit balances). We ran both models in parallel for several months and members of ALCO scrutinized the results. Additionally, rigorous statistical validation of the new model was conducted prior to its adoption.

Regardless of the model used, estimating the impact on net interest income and EVE requires that we assess a number of variables and make various assumptions in managing our exposure to changes in interest rates. The assessments address deposit withdrawals and deposit product migration (e.g., customers moving money from checking accounts to certificates of deposit), competitive pricing (e.g., existing loans and deposits are assumed to roll into new loans and deposits at similar spreads relative to benchmark interest rates), loan and security prepayments, and the effects of other similar embedded options. As a result of uncertainty about the maturity and repricing characteristics of both deposits and loans, we estimate ranges of possible net interest income and EVE results under a variety of assumptions and scenarios. The modeled results are highly sensitive to the assumptions

Table of Contents

used for deposits that do not have specific maturities, such as checking, savings and money market accounts, and also to prepayment assumptions used for loans with prepayment options. We use historical regression analysis as a guide to setting such assumptions; however, due to the current low interest rate environment, which has little historical precedent, estimated deposit durations may not reflect actual future results. Additionally, competition for funding in the marketplace has and may again result in changes of deposit pricing on interest-bearing accounts that is greater or less than changes in benchmark interest rates such as LIBOR or the federal funds rate.

Under most rising interest rate environments, we would expect some customers to move balances in demand deposits to interest-bearing accounts such as money market, savings, or CDs. The models are particularly sensitive to the assumption about the rate of such migration. In order to capture the sensitivity of our models to this risk, we estimate a range of possible outcomes for interest sensitivity under “fast” and “slow” movements of client funds out of noninterest-bearing deposits and into interest-bearing sources of funds.

In addition, we assume certain correlation rates, often referred to as a “deposit beta,” of interest-bearing deposits, wherein the rates paid to customers change at a different pace when compared to changes in benchmark interest rates. Generally, certificates of deposit are assumed to have a high correlation rate, while interest-on-checking accounts are assumed to have a lower correlation rate. Actual results may differ materially due to factors including competitive pricing, money supply, credit worthiness of the Company, and so forth; however, we use our historical experience as well as industry data to inform our assumptions. The aforementioned migration and correlation assumptions result in deposit durations presented in Schedule 25.

For comparative purposes, we applied the new model to the December 31, 2014 balances; these results are presented in the following schedule.

The decrease from December 31, 2014 in interest rate sensitivity for upward shocks in rates was driven by

purchases of securities, addition of swap contracts in which we receive a fixed rate, and the previously mentioned changes in modeled demand deposit behavior. For the down 100bp shock, interest rate sensitivity increased due to the fact that negative shocked rates are not allowed. As the Fed Funds target rate was 0.25% as of December 31, 2014 and 0.50% as of December 31, 2015 the -100bp shock as of the latter date represented a larger shock for short-term rates.

Our focus on business banking also plays a significant role in determining the nature of the Company’s asset-liability management posture. At December 31, 2015 and 2014, approximately 80% and 78%, respectively, of the Company’s commercial lending and CRE portfolios were variable-rate and primarily tied to either the prime rate or LIBOR. In addition, certain of our consumer loans also have variable interest rates. See Schedule 11 for further information on fixed and variable interest rates of the loan portfolio.

Largely due to competitive pressures, the favorable impact on loan yield from the use of interest rate floors has diminished. As of December 31, 2015 and 2014, approximately 33% and 37%, respectively, of all of the Company’s variable-rate loan balances contain floors. Of the loans with floors, approximately 44% and 55% of the balances at these same respective dates were priced at the floor rates, which were above the “index plus spread” rate by an average of 0.33% and 0.53%, respectively.

At December 31, 2015, the Company held $1,388 million (notional amount) of interest rate swap agreements. See Notes 7 and 20 of the Notes to Consolidated Financial Statements for additional information regarding derivative instruments.

Market Risk – Fixed Income
We engage in the underwriting and trading of municipal securities. This trading activity exposes us to a risk of loss arising from adverse changes in the prices of these fixed income securities.

At December 31, 2015, we had a relatively small amount, $48 million, of trading assets and $30 million of securities sold, not yet purchased, compared with $71 million and $24 million, at December 31, 2014.

We are exposed to market risk through changes in fair value. We are also exposed to market risk for interest rate swaps used to hedge interest rate risk. Changes in the fair value of AFS securities and in interest rate swaps that qualify as cash flow hedges are included in AOCI for each financial reporting period. During 2015, the after-tax change in AOCI attributable to AFS and HTM securities improved by $74 million compared to a $77 million improvement in the same prior year period.

Market Risk – Equity Investments
Through our equity investment activities, we own equity securities that are publicly traded. In addition, we own equity securities in companies and governmental entities, e.g., Federal Reserve Bank and FHLBs, that are not publicly traded. The accounting for equity investments may use the cost, fair value, equity, or full consolidation methods of accounting, depending on our ownership position and degree of involvement in influencing the investees’ affairs. Regardless of the accounting method, the value of our investment is subject to fluctuation. Because the fair value of these securities may fall below our investment costs, we are exposed to the possibility of loss. Equity investments in private and public companies are approved, monitored and evaluated by the Company’s Equity Investment Committee consisting of members of management.
We hold both direct and indirect investments in predominately pre-public companies through various predominantly SBIC venture capital funds. Our equity exposure to these investments was approximately $113 million at December 31, 2015 and $86 million at December 31, 2014. On occasion, some of the companies within our SBIC investments may issue an initial public offering. In this case, the fund is generally subject to a lockout period before liquidating the investment which can introduce additional market risk. As of December 31, 2015 we had direct SBIC investments of approximately $25 million of publicly traded stocks.
Additionally, Amegy has an alternative investments portfolio. These investments are primarily directed towards equity buyout and mezzanine funds with a key strategy of deriving ancillary commercial banking business from the portfolio companies. Early stage venture capital funds are generally not a part of the strategy because the underlying companies are typically not creditworthy. The carrying value of Amegys equity investments was $21 million at December 31, 2015 and $38 million at December 31, 2014.
These PEIs are subject to the provisions of the Dodd-Frank Act. The VR of the Dodd-Frank Act, as published in December 2013 and amended in January 2014, prohibits banks and bank holding companies from holding PEIs beyond July 21, 2016, as currently extended, except for SBIC funds. The FRB has announced its intention to grant an additional one-year extension to July 21, 2017. As of December 31, 2015, such prohibited PEIs amounted to $18 million, with an additional $7 million of unfunded commitments (see Notes 5 and 17 of the Notes to Consolidated Financial Statements for more information). We currently do not believe that this divestiture requirement will ultimately have a material impact on our financial statements.
Our earnings from these investments, and the potential volatility of these earnings, are expected to decline over the next several years and will ultimately cease.

Liquidity Risk Management
Overview
Liquidity risk is the possibility that our cash flows may not be adequate to fund our ongoing operations and meet our commitments in a timely and cost-effective manner. Since liquidity risk is closely linked to both credit risk and market risk, many of the previously discussed risk control mechanisms also apply to the monitoring and management of liquidity risk. We manage our liquidity to provide adequate funds to meet our anticipated financial and contractual obligations, including withdrawals by depositors, debt and capital service requirements, and lease obligations, as well as to fund customers’ needs for credit.

Overseeing liquidity management is the responsibility of ALCO, which implements a Board-adopted corporate Liquidity and Funding Policy. This policy addresses monitoring and maintaining adequate liquidity, diversifying funding positions, and anticipating future funding needs. The policy also includes liquidity ratio guidelines, such as the “time-to-required funding” and LCR, that are used to monitor the liquidity positions of the Parent and ZB, N.A., as well as various stress test and liquid asset measurements for the Parent and ZB, N.A. liquidity.

The management of liquidity and funding is performed centrally for the Parent and jointly by the Parent and bank management for its subsidiary bank. The Treasury Department performs this management centrally, under the direction of the Corporate Treasurer, with oversight by ALCO. The Treasurer is responsible for recommending changes to existing funding plans, as well as to the Company’s Liquidity Policy. These recommendations must be submitted for approval to ALCO, and changes to the Policy also must be approved by the Company’s ERMC and the Board of Directors. The Company has adopted policy limits that govern liquidity risk. The policy requires the Company to maintain a buffer of highly liquid assets sufficient to cover cash outflows as the result of a severe liquidity crisis. The Company targets a buffer of highly liquid assets at the Parent to cover 18-24 months of cash outflows under a scenario with limited cash inflows, and maintains a minimum policy limit of not less than 12 months. The Company’s banking subsidiary ZB, N.A. exceeds the regulatory requirements of the Modified LCR that mandates a buffer of HQLA to cover 70% of 30-day cash outflows under the assumptions mandated in the Final Liquidity Rule. Additionally, the Company performs monthly liquidity stress testing using a set of internally generated scenarios representing severe liquidity constraints over a 12-month horizon. ZB, N.A. maintains a buffer of highly liquid assets consisting of cash, U.S. Agency, and U.S. Government Sponsored Entity securities to cover 30-day cash outflows under liquidity stress tests and maintains a contingency funding plan to identify funding sources that would be utilized over the extended 12-month horizon. Throughout 2015 and as of December 31, 2015, the Company complied with this policy.

Liquidity Regulation
In September 2014, U.S. banking regulators issued a final rule that implements a quantitative liquidity requirement in the U.S. generally consistent with the LCR minimum liquidity measure established under the Basel III liquidity framework. Under this rule, we are subject to a modified LCR standard, which requires a financial institution to hold an adequate amount of unencumbered High Quality Liquid Assets (“HQLA”) that can be converted into cash easily and immediately in private markets to meet its liquidity needs for a short-term liquidity stress scenario. This rule became applicable to us on January 1, 2016. We have calculated that, if the rule were applicable to us as of December 31, 2015, we would be in compliance with the requirement to maintain a modified LCR of at least 100%.

Zions’ internal liquidity stress testing program as contained in its policy complies with the requirements of the Enhanced Prudential Standards for liquidity management (Reg. YY).

The Basel III liquidity framework includes a second minimum liquidity measure, the Net Stable Funding Ratio (“NSFR”), which requires a financial institution to maintain a stable funding profile in relation to the characteristics of its on- and off-balance sheet activities. On October 31, 2014, the Basel Committee on Banking Supervision issued its final standards for this ratio, entitled Basel III: The Net Stable Funding Ratio. Based upon this Basel III publication, we believe we would meet the minimum NSFR if such requirement were currently effective. However,

the FRB has not yet proposed regulations to implement these Basel Committee standards. We continue to monitor these developments.

Indeterminable maturity deposits include noninterest-bearing demand, savings and money market, and non-time foreign.

Commitments to make venture and other noninterest-bearing investments do not have defined maturity dates. They have therefore been considered due on demand, maturing in one year or less.

In addition to the commitments specifically noted in Schedule 28, we enter into a number of contractual commitments in the ordinary course of business. These include software licensing and maintenance, telecommunications services, facilities maintenance and equipment servicing, supplies purchasing, and other goods and services used in the operation of our business. Generally, these contracts are renewable or cancelable at least annually, although in some cases to secure favorable pricing concessions, we have committed to contracts that may extend to several years.

We also enter into derivative contracts under which we are required either to receive or pay cash, depending on changes in interest rates. These contracts are carried at fair value on the balance sheet with the fair value representing the net present value of the expected future cash receipts and payments based on market rates of interest. The fair value of the contracts changes daily as interest rates change. See Note 7 of the Notes to Consolidated Financial Statements for further information on derivative contracts.

Liquidity Management Actions
Consolidated cash, interest-bearing deposits held as investments, and security resell agreements at the Parent and its subsidiaries decreased to $7.4 billion at December 31, 2015 from $9.2 billion at December 31, 2014. The $1.8 billion decrease during 2015 resulted primarily from (1) an increase in investment securities, (2) Net loan originations, (3) repayment of long-term debt, (4) tender offer and purchase of preferred stock, and (5) dividends on common and preferred stock These decreases were partially offset by an increase in deposits and net cash provided by operating activities.

Table of Contents

Our AFS investment securities increased by $3.8 billion during 2015. This increase was primarily due to the purchase of short-to-medium duration agency guaranteed mortgage-backed securities, partially offset by the sale of the remaining portfolio of CDO securities. We have been adding to our investment portfolio as a result of the need for a permanent buffer of highly liquid assets to satisfy the new LCR rules and more broadly, to maintain a sufficient buffer of highly liquid assets to meet projected liquidity needs under our monthly liquidity stress tests. We expect to continue to deploy cash and short-term investments into highly liquid assets in the next several quarters.

During 2015 we completed a tender offer to purchase $176 million of our Series I preferred stock.

We made cash payments totaling $288 million during 2015 for our long-term debt which matured or were redeemed and did not incur any new long-term debt during the same time period. See Note 12 for additional detail about debt redemptions and maturities during 2015.

Parent Company Liquidity – The Parent’s cash requirements consist primarily of debt service, investments in and advances to subsidiaries, operating expenses, income taxes, and dividends to preferred and common shareholders. The Parent’s cash needs are usually met through dividends from its subsidiaries, interest and investment income, subsidiaries’ proportionate share of current income taxes, and long-term debt and equity issuances.

Cash and interest-bearing deposits held as investments at the Parent decreased to $0.8 billion at December 31, 2015 from $1.0 billion at December 31, 2014. The $0.2 billion decrease during 2015 was primarily a result of (1) repayment of long-term debt, (2) tender offer and purchase of preferred stock, and (3) dividends on common and preferred stock. These decreases were partially offset by (1) dividends received from its subsidiary banks on common and preferred stock, (2) net cash provided by operating activities, and (3) a decrease in investment securities. See Notes 12 and 13 of the Notes to Consolidated Financial Statements for additional information about our long-term debt and equity transactions.

During 2015, the Parent received common dividends and return of common equity totaling $192 million and preferred dividends totaling $42 million from its subsidiary banks. During 2014, the Parent received from its subsidiary banks $190 million for common dividends and return of common equity and $46 million for preferred dividends. At December 31, 2015, ZB, N.A., had approximately $604 million available for the payment of dividends under current capital regulations. Following the close of business on December 31, 2015, we completed the merger of our subsidiary banks, resulting in one bank with a legal name of ZB, National Association. (see Note 1 for a more detailed discussion). The dividends that ZB, N.A. can pay to the Parent are restricted by current and historical earning levels, retained earnings, and risk-based and other regulatory capital requirements and limitations. During 2015, all of our subsidiary banks recorded a profit. We expect that this profitability will be sustained under the new single charter bank previously discussed, thus permitting continued payments of dividends to the Parent during 2016 although dividend capacity to the Parent will change.

General financial market and economic conditions impact our access to, and cost of, external financing. Access to funding markets for the Parent and subsidiary banks is also directly affected by the credit ratings received from various rating agencies. The ratings not only influence the costs associated with the borrowings, but can also influence the sources of the borrowings. The debt ratings and outlooks issued by the various rating agencies for the Company did not change during 2015, except that Moody’s upgraded the Company’s subordinated debt to Ba1 from Ba2 and both Moody’s and Dominion Bond Rating Service (“DBRS”) revised its outlook to positive from stable. Standard & Poor’s, Fitch, DBRS, and Kroll all rate the Company’s senior debt at an investment-grade level, while Moody’s rates the Company’s senior debt as Ba1 (one notch below investment-grade). In addition, all of the previously mentioned rating agencies, except Kroll, rate the Company’s subordinated debt as noninvestment-grade.

The Parent’s cash payments for interest, reflected in operating expenses, decreased to $51 million in 2015 from $96 million in 2014 as a result of a net repayment of long-term debt of $0.3 billion and $1.2 billion during 2015 and 2014, respectively. Cash payments for interest are expected to continue to decrease during 2016 as a result of the debt repayments during 2015. Additionally, the Parent paid approximately $108 million and $96 million of total dividends on preferred stock and common stock for the same periods. Preferred stock dividends will decrease during 2016 as a result of the tender offer and purchase of approximately $176 million of our series I preferred stock.
Note 23 of the Notes to Consolidated Financial Statements contains the Parent’s statements of income and cash flows for 2015, 2014 and 2013, as well as its balance sheets at December 31, 2015 and 2014.
The Parent’s long-term debt maturities during 2016 consist of $89 million senior notes due on June 20, 2016. At December 31, 2015, maturities of our long-term senior and subordinated debt ranged from June 2016 to September 2028, with effective interest rates from 3.60% to 6.95%.
See Note 12 of the Notes to Consolidated Financial Statements for a complete summary of our long-term debt.
Subsidiary Bank Liquidity – ZB, N.A.’s primary source of funding is its core deposits, consisting of demand, savings and money market deposits, and time deposits under $250,000. On a consolidated basis, the Company’s loan to total deposit ratio is 80.7% as of December 31, 2015, compared to 83.7% as of December 31, 2014. Total deposits increased by $2.5 billion to $50.4 billion at December 31, 2015, compared to $47.9 billion at December 31, 2014, primarily due to a $1.7 billion increase in noninterest-bearing demand deposits and a $1.1 billion increase in savings and money market deposits. This increase was partially offset by a $276 million decrease in time deposits. Also, during 2015, the subsidiary banks redeployed approximately $1.8 billion of interest-bearing deposits and security resell agreements to short-to-medium duration agency guaranteed mortgage-backed securities. ZB, N.A.’s long-term senior debt ratings were the same as the Parent, except Standard & Poor’s was BBB.
The FHLB system and Federal Reserve Banks have been and are a source of back-up liquidity, and from time to time, have been a significant source of funding for each of our subsidiary banks. Subsequent to the charter consolidation on December 31, 2015, ZB, N.A. is a member of the FHLB of Des Moines. The FHLB allows

71


Table of Contents

member banks to borrow against their eligible loans to satisfy liquidity and funding requirements. The bank is required to invest in FHLB and Federal Reserve stock to maintain their borrowing capacity. We do not believe that the subsidiary bank mergers will adversely impact bank liquidity or funding.
At December 31, 2015, the amount available for additional FHLB and Federal Reserve borrowings was approximately $13.4 billion. The amount available for additional FHLB and Federal Reserve borrowings is not expected to decrease as a result of the subsidiary bank mergers. Loans with a carrying value of approximately $19.4 billion at December 31, 2015, and $22.5 billion at December 31, 2014 have been pledged at the Federal Reserve and various FHLBs as collateral for current and potential borrowings. During 2015, we repaid our outstanding $22 million of long-term borrowings with the FHLB. We had no short-term FHLB or Federal Reserve borrowings outstanding at December 31, 2015 or December 31, 2014. At December 31, 2015, our total investment in FHLB and Federal Reserve stock was $68 million and $123 million, respectively, compared to $104 million and $121 million at December 31, 2014.
Our investment activities can provide or use cash, depending on the asset liability management posture taken. During 2015, HTM & AFS investment securities’ activities resulted in a net increase in investment securities and a net $3.8 billion decrease in cash compared with a net $71 million decrease in cash for 2014.
Maturing balances in our subsidiary banks’ loan portfolios also provide additional flexibility in managing cash flows. Lending and purchase activity for 2015 resulted in a net cash outflow of $0.6 billion compared to a net cash outflow of $1.1 billion for 2014.
During 2015, we paid income taxes of $132 million, compared to $183 million during 2014.

Operational Risk Management
Operational risk is the risk to current or anticipated earnings or capital arising from inadequate or failed internal processes or systems, human errors or misconduct, or adverse external events. In our ongoing efforts to identify and manage operational risk, we have an Enterprise Risk Management department whose responsibility is to help employees, management and the Board of Directors to assess, understand, measure, and monitor risk in accordance with our Risk Appetite Framework. We have documented both controls and the Control Self-Assessment related to financial reporting under the 2013 framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) and the Federal Deposit Insurance Corporation Improvement Act of 1991.
To manage and minimize our operational risk, we have in place transactional documentation requirements; systems and procedures to monitor transactions and positions; systems and procedures to detect and mitigate attempts to commit fraud, penetrate our systems or telecommunications, access customer data, and/or deny normal access to those systems to our legitimate customers; regulatory compliance reviews; and periodic reviews by the Company’s Internal Audit and Credit Examination departments. Reconciliation procedures have been established to ensure that data processing systems consistently and accurately capture critical data. Further, we undertake significant efforts to maintain contingency and business continuity plans for operational support in the event of natural or other disasters. We also mitigate operational risk through the purchase of insurance, including errors and omissions and professional liability insurance.
We are continually improving our oversight of operational risk, including enhancement of risk identification, risk and control self-assessments, and antifraud measures, which are reported on a regular basis to enterprise management committees. The Operational Risk Committee reports to the ERMC, which reports to the ROC. Additional measures have been taken to increase oversight by Enterprise Risk Management and Operational Risk Management through the strengthening of new product reviews, enhancements to the Vendor Management and Vendor Risk Management framework, enhancements to the Business Continuity and Disaster Recovery program, and the establishment of Fraud Risk Oversight, Incident Response Oversight and Technology Project Oversight programs. Significant enhancements have also been made to governance and reporting, including the establishment of Policy and Committee Governance programs and the creation of an Enterprise Risk Profile and Operational Risk Profile.

The number and sophistication of attempts to disrupt or penetrate our critical systems, sometimes referred to as hacking, cyberfraud, cyberattacks, cyberterrorism, or other similar names, also continue to grow. On a daily basis, the Company, its customers, and other financial institutions are subject to a large number of such attempts. We have established systems and procedures to monitor, thwart or mitigate damage from such attempts. However, in some instances we, or our customers, have been victimized by cyberfraud (our related losses have not been material), or some of our customers have been temporarily unable to routinely access our online systems as a result of, for example, distributed denial of service attacks. We continue to review this area of our operations to help ensure that we manage this risk in an effective manner.

CAPITAL MANAGEMENT
Overview
The Board of Directors is responsible for approving the policies associated with capital management. The Board has established the Capital Management Committee (“CMC”) whose primary responsibility is to recommend and administer the approved capital policies that govern the capital management of the Company and its subsidiary bank. Other major CMC responsibilities include:
Setting overall capital targets within the Board-approved capital policy, monitoring performance compared to the Company’s Capital Policy limits, and recommending changes to capital including dividends, common stock repurchases, subordinated debt, and changes in major strategies to maintain the Company and its subsidiary bank at well-capitalized levels;
Maintaining an adequate capital cushion to withstand adverse stress events while continuing to meet the lending needs of its customers, and to provide reasonable assurance of continued access to wholesale funding, consistent with fiduciary responsibilities to depositors and bondholders; and
Reviewing agency ratings of the Parent and ZB, N.A., and establishing target ratings.
The Company has a fundamental financial objective to consistently produce superior risk-adjusted returns on its shareholders’ capital. We believe that a strong capital position is vital to continued profitability and to promoting depositor and investor confidence. Specifically, it is the policy of the Parent and ZB, N.A. to:
Maintain sufficient capital to support current needs;
Maintain an adequate capital cushion to withstand future adverse stress events while continuing to meet borrowing needs of its customers; and
Meet fiduciary responsibilities to depositors and bondholders while managing capital distributions to shareholders through dividends and repurchases of common stock so as to be consistent with Federal Reserve guidelines SR 09-04 and 12 U.S.C §§ 56 and 60.

Capital Plan and Stress Tests
The CMC oversees the Company’s capital stress testing under a variety of adverse economic and market scenarios. We have established processes to periodically conduct stress tests to evaluate potential impacts to the Company under hypothetical economic scenarios. These stress tests facilitate our contingency planning and management of capital and liquidity within quantitative limits reflecting the Board of Directors’ risk appetite. These processes are also used to complete the Company’s DFAST, as required by the Dodd-Frank Act, and CCAR as required by the Federal Reserve.

Filing a capital plan with the Federal Reserve based on stress testing and documented sound policies, processes, models, controls, and governance practices, and the subsequent review by the Federal Reserve, is an annual regulatory requirement. This capital plan, which is subject to objection by the Federal Reserve, governs all of the Company’s capital and significant unsecured debt financing actions for a period of five quarters. Among the actions governed by the capital plan are the repurchase of outstanding capital securities and the timing of new capital issuances, and whether the Company can pay or increase dividends. Any such action not included in a capital plan

73


Table of Contents

to which the Federal Reserve has not objected cannot be executed without submission of a revised stress test and capital plan for Federal Reserve review and non-objection; de minimis changes are allowed without a complete plan resubmission, subject to receipt of a Federal Reserve non-objection. Regulations require Company disclosure of these stress tests results.

We submitted our 2015 capital plan and stress test results to the FRB on January 5, 2015. In our capital plan, we were required to forecast, under a variety of economic scenarios for nine quarters ending the fourth quarter of 2016, our estimated regulatory capital ratios, including our Tier 1 common ratio associated with the Basel I capital rules, our CET1 ratio under the Basel III capital rules, and our GAAP tangible common equity ratio. On March 11, 2015, we announced that the Federal Reserve notified us that it did not object to the capital actions outlined in our 2015 capital plan. The plan included (1) the increase of the quarterly common dividend to $0.06 per share beginning in the second quarter of 2015; (2) the continued payment of preferred dividends at the current rates; and (3) up to $300 million in total reduction of preferred equity.

The Company’s stress test results were significantly different from those modeled by the FRB, as the FRB estimated that the Company’s minimum Tier 1 Common ratio in the severely adverse scenario was 5.1%, just above the 5.0% minimum. Since the release of the FRB’s modeled results, we have undertaken several actions designed in part to improve the Company’s risk profile under the CCAR stress tests. These actions include selling parts of the investment portfolio, extending the duration of the investment portfolio, and limiting growth in certain loan categories which are perceived as risky in the CCAR stress test.

During the second quarter of 2015, we completed our mid-cycle capital stress test as required under DFAST. The results demonstrated that we maintained sufficient capital to withstand a severe economic downturn. Detailed disclosure of the mid-cycle stress test results can be found on the Company’s website.

As discussed subsequently, we increased our common dividend to $0.06 in the second quarter of 2015. In November 2015, we purchased and retired $180 million of our Series I preferred stock pursuant to a tender offer announced in October 2015. Our 2015 capital plan, which runs through the second quarter of 2016, allows for an additional use of up to $120 million of cash for preferred stock redemptions. The ultimate determination of future preferred stock reductions will depend on a number of factors, including market conditions and the receptivity of preferred investors to the terms of any preferred stock redemption offers, as well as the effect of other steps we may explore as we seek to manage our capital in light of the most recent round of stress tests, any of which could result in a reduction or delay of further preferred equity reductions. We expect to manage any further reduction of preferred equity such that total tier 1 capital does not decline materially.

We are currently preparing our 2016 capital plan, which is due to the Federal Reserve on April 5, 2016. In addition, our Dodd-Frank Act mid-cycle stress test, based upon the Company’s June 30, 2016 financial position, is due on October 5, 2016.

Basel III
The Basel III capital rules, which effectively replaced the Basel I rules, became effective for the Company on January 1, 2015 (subject to phase-in periods for certain of their components). In 2013, the FRB, FDIC, and OCC published final rules (the “Basel III Capital Rules”) establishing a new comprehensive capital framework for U.S. banking organizations. The rules implement the Basel Committee’s December 2010 framework, commonly referred to as Basel III, for strengthening international capital standards as well as certain provisions of the Dodd-Frank Act. The Basel III capital rules substantially revised the risk-based capital requirements applicable to bank holding companies and depository institutions, including the Company, compared to the Basel I U.S. risk-based capital rules.

Table of Contents

Under prior Basel I capital standards, the effects of AOCI items included in capital were excluded for purposes of determining regulatory capital and capital ratios. As a “non-advanced approaches banking organization,” we made a one-time permanent election as of January 1, 2015 to continue to exclude these items, as allowed under the Basel III Capital Rules.

We met all capital adequacy requirements under the Basel III Capital Rules based upon a 2015 phase-in as of December 31, 2015, and believe that we would meet all capital adequacy requirements on a fully phased-in basis if such requirements were currently effective.

A detailed discussion of Basel III requirements, including implications for the Company, is contained on page 9 of the “Capital Standards – Basel Framework” section under Part 1, Item 1 in this Annual Report on Form 10-K.

Capital Management Actions
Total shareholders’ equity increased by 1.9% from $7.4 billion at December 31, 2014 to $7.5 billion at December 31, 2015. The increase in total shareholders’ equity is primarily due to net income of $309 million and to the sale of the Company’s remaining portfolio of CDO securities, which was the primary driver of the $73 million increase in AOCI. This increase was partially offset by the $176 million tender offer and repurchase of a portion of our Series I preferred stock and $108 million of dividends recorded on preferred and common stock.

The common dividend rate was increased to $0.06 per share during the second quarter of 2015 from $0.04 per share paid since the second quarter of 2013. We paid $45.2 million in dividends on common stock during 2015, compared to $31.3 million during 2014. During its February 2016 meeting, the Board of Directors declared a dividend of $0.06 per common share payable on February 25, 2016 to shareholders of record on February 18, 2016.

We recorded preferred stock dividends of $62.9 million for 2015 and $71.9 million for 2014. Dividends on preferred stock recorded in 2014 included accruals of $7.0 million. Preferred stock dividends will decrease during 2016 as a result of the purchase of $180 million of our series I preferred stock discussed previously, and any subsequent preferred stock reduction allowed in our 2015 capital plan.

Banking organizations are required by capital regulations to maintain adequate levels of capital as measured by several regulatory capital ratios. The Company’ capital ratios as of December 31, 2015 under Basel III and December 31, 2014 and 2013 under Basel I are shown in Schedule 31.

Basel III capital ratios became effective January 1, 2015 and are based upon a 2015 phase-in.

Note 18 of the Notes to Consolidated Financial Statements provides additional information on risk-based capital.

At December 31, 2015, Basel III regulatory tier 1 risk-based capital and total risk-based capital was $6.6 billion and $7.5 billion, respectively. Basel I regulatory tier 1 risk-based capital and total risk-based capital at December 31, 2014 was $6.6 billion and $7.4 billion, respectively.

GAAP to NON-GAAP RECONCILIATIONS
1. Basel I Tier 1 common capital
The Basel I capital rules were replaced by the Basel III capital rules that became effective for the Company on January 1, 2015 (subject to phase-in periods for certain of their components). The Basel III capital rules include the CET1 capital ratio, which is the core capital component of the Basel III rules and a key ratio considered by regulators, investors and analysts. The calculation of the CET1 capital ratio, as defined under Basel III rules, is considered an acceptable ratio by GAAP for financial institutions and, accordingly, does not require reconciliation to GAAP.
There is a difference in the calculation of the CET1 capital ratio under Basel III rules and the calculation of the tier 1 common (“T1C”) capital ratio under Basel I rules. We present the calculation of key regulatory capital ratios, including the T1C capital ratio, using the governing definition at the end of each quarter, taking into account applicable phase-in rules.
While we were subject to Basel I capital rules prior to 2015, the Federal Reserve and other banking regulators assessed a bank’s capital adequacy based on tier 1 capital, the calculation of which was codified in federal banking regulations. However, Basel I rules did not include a definition for T1C capital and thus it was considered a non-GAAP measure requiring reconciliation to GAAP.
Schedule 32 provides a reconciliation for prior periods of total shareholders’ equity (GAAP) to tier 1 capital (regulatory at the subject dates) and to T1C capital (non-GAAP) using Basel I U.S. regulatory treatment, and the resulting T1C capital ratio.

For items 2, 3, and 4, the identified adjustments to reconcile from the applicable GAAP financial measures to the non-GAAP financial measures are included where applicable in financial results or in the balance sheet presented in accordance with GAAP. We consider these adjustments to be relevant to ongoing operating results and financial position.
We believe that excluding the amounts associated with these adjustments to present the non-GAAP financial measures provides a meaningful base for period-to-period and company-to-company comparisons, which will assist regulators, investors, and analysts in analyzing the operating results or financial position of the Company and in predicting future performance. These non-GAAP financial measures are used by management to assess the performance of the Company’s business or its financial position for evaluating bank reporting segment performance, for presentations of the Company’s performance to investors, and for other reasons as may be requested by investors and analysts. We further believe that presenting these non-GAAP financial measures will permit investors and analysts to assess our performance on the same basis as that applied by management.
Non-GAAP financial measures have inherent limitations, are not required to be uniformly applied, and are not audited. Although these non-GAAP financial measures are frequently used by stakeholders to evaluate a company,

they have limitations as an analytical tool, and should not be considered in isolation or as a substitute for analysis of results reported under GAAP.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ESTIMATES
Note 1 of the Notes to Consolidated Financial Statements contains a summary of the Company’s significant accounting policies. Discussed below are certain significant accounting policies that we consider critical to the Company’s financial statements. These critical accounting policies were selected because the amounts affected by them are significant to the financial statements. Any changes to these amounts, including changes in estimates, may also be significant to the financial statements. We believe that an understanding of these policies, along with the related estimates we are required to make in recording the financial transactions of the Company, is important to have a complete picture of the Company’s financial condition. In addition, in arriving at these estimates, we are required to make complex and subjective judgments, many of which include a high degree of uncertainty. The following discussion of these critical accounting policies includes the significant estimates related to these policies. We have discussed each of these accounting policies and the related estimates with the Audit Committee of the Board of Directors.

We have included, where applicable in this document, sensitivity schedules and other examples to demonstrate the impact of the changes in estimates made for various financial transactions. The sensitivities in these schedules and examples are hypothetical and should be viewed with caution. Changes in estimates are based on variations in assumptions and are not subject to simple extrapolation, as the relationship of the change in the assumption to the change in the amount of the estimate may not be linear. In addition, the effect of a variation in one assumption is in reality likely to cause changes in other assumptions, which could potentially magnify or counteract the sensitivities.

Fair Value Estimates
We measure or monitor many of our assets and liabilities on a fair value basis. Fair value is the price that could be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. To increase consistency and comparability in fair value measurements, current accounting guidance has established a three-level hierarchy to prioritize the valuation inputs among (1) observable inputs that reflect quoted prices in active markets, (2) inputs other than quoted prices with observable market data, and (3) unobservable data such as the Company’s own data or single dealer nonbinding pricing quotes.

When observable market prices are not available, fair value is estimated using modeling techniques such as discounted cash flow analysis. These modeling techniques utilize assumptions that market participants would use in pricing the asset or the liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset, the related life of the asset and applicable growth rate, the risk of nonperformance, and other related assumptions.

The selection and weighting of the various fair value techniques may result in a fair value higher or lower than carrying value. Considerable judgment may be involved in determining the amount that is most representative of fair value.

For assets and liabilities recorded at fair value, the Company’s policy is to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements for those items where there is an active market. In certain cases, when market observable inputs for model-based valuation techniques may not be readily available, the Company is required to make judgments about assumptions market participants would use in estimating the fair value of the financial instrument. The models used to determine fair value adjustments are regularly evaluated by management for relevance under current facts and circumstances.

Changes in market conditions may reduce the availability of quoted prices or observable data. For example, reduced liquidity in the capital markets or changes in secondary market activities could result in observable market inputs

80


Table of Contents

becoming unavailable. When market data is not available, the Company would use valuation techniques requiring more management judgment to estimate the appropriate fair value.

Fair value is used on a recurring basis for certain assets and liabilities in which fair value is the primary measure of accounting. Fair value is used on a nonrecurring basis to measure certain assets or liabilities (including HTM securities, loans held for sale, and OREO) for impairment or for disclosure purposes in accordance with current accounting guidance.

Impairment analysis also relates to long-lived assets, goodwill, and core deposit and other intangible assets. An impairment loss is recognized if the carrying amount of the asset is not likely to be recoverable and exceeds its fair value. In determining the fair value, management uses models and applies the techniques and assumptions previously discussed.

Investment securities are valued using several methodologies, which depend on the nature of the security, availability of current market information, and other factors. Investment securities in an unrealized loss position are formally reviewed on a quarterly basis for the presence of OTTI. OTTI is considered to have occurred if its fair value is below amortized cost and (1) we intend to sell the security, or (2) it is “more likely than not” we will be required to sell the security before recovery of its amortized cost basis, or (3) the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. The “more likely than not” criteria is a lower threshold than the “probable” criteria.

Notes 1, 5, 7, 9, and 20 of the Notes to Consolidated Financial Statements and “Investment Securities Portfolio” on page 44 contain further information regarding the use of fair value estimates.

Allowance for Credit Losses
The ACL includes the allowance for loan losses and the RULC. The allowance for loan losses provides for probable losses that have been identified with specific customer relationships and for probable losses believed to be inherent in the loan portfolio, but which have not been specifically identified. The determination of the appropriate level of the allowance is based on periodic evaluations of the portfolios. This process includes both quantitative and qualitative analyses, as well as a qualitative review of the results. The qualitative review requires a significant amount of judgment, and is described in more detail in Note 6 of the Notes to Consolidated Financial Statements.

The RULC provides for potential losses associated with off-balance sheet lending commitments and standby letters of credit. The reserve is estimated using the same procedures and methodologies as for the allowance for loan losses, plus assumptions regarding the probability and amount of unfunded commitments being drawn.

There are numerous components that enter into the evaluation of the allowance for loan losses. Although we believe that our processes for determining an appropriate level for the allowance adequately address the various components that could potentially result in credit losses, the processes and their elements include features that may be susceptible to significant change. Any unfavorable differences between the actual outcome of credit-related events and our estimates could require an additional provision for credit losses. As an example, if the PD risk grade, for all pass-graded commercial and CRE loans, was immediately downgraded one grade on our internal risk grading scale, the quantitatively determined amount of the allowance for loan losses at December 31, 2015 would increase by approximately $84 million. This sensitivity analysis is hypothetical and has been provided only to indicate the potential impact that changes in risk grades may have on the allowance estimation process.

Although the qualitative process is subjective, it represents the Company’s best estimate of qualitative factors impacting the determination of the allowance for loan losses. Such factors include, but are not limited to, national and regional economic trends and indicators. We believe that given the procedures we follow in determining the allowance for loan losses for the loan portfolio, the various components used in the current estimation processes are appropriate.

Accounting for Goodwill
Goodwill is initially recorded at fair value and is subsequently evaluated at least annually for impairment in accordance with current accounting guidance. We perform this annual test as of October 1 of each year, or more often if events or circumstances indicate that carrying value may not be recoverable. The goodwill impairment test for a given reporting unit (generally one of our banking segments) compares its fair value with its carrying value. If the carrying amount exceeds fair value, an additional analysis must be performed to determine the amount, if any, by which goodwill is impaired.

To determine the fair value, we generally use a combination of up to three separate methods: comparable publicly traded financial service companies (primarily banks and bank holding companies) in the Western and Southwestern states (“Market Value”); where applicable, comparable acquisitions of financial services companies in the Western and Southwestern states (“Transaction Value”); and the discounted present value of management’s estimates of future cash flows. Critical assumptions that are used as part of these calculations include:
selection of comparable publicly traded companies based on location, size, and business focus and composition;
selection of market comparable acquisition transactions based on location, size, business focus and composition, and date of the transaction;
the discount rate, which is based on Zions’ estimate of its cost of capital, applied to future cash flows;
the projections of future earnings and cash flows of the reporting unit;
the relative weight given to the valuations derived by the three methods described; and
the control premium associated with reporting units.
We apply a control premium in the Market Value approach to determine the reporting units’ equity values. Control premiums represent the ability of a controlling shareholder to change how the Company is managed and can cause the fair value of a reporting unit as a whole to exceed its market capitalization. Based on a review of historical bank acquisition transactions within the Company’s geographic footprint, and a comparison of the target banks’ market values 30 days prior to the announced transaction to the deal value, we have determined that a control premium of 25% was appropriate at the most recent test date.

Since estimates are an integral part of the impairment computations, changes in these estimates could have a significant impact on any calculated impairment amount. Estimates include economic conditions, which impact the assumptions related to interest and growth rates, loss rates and imputed cost of equity capital. The fair value estimates for each reporting unit incorporate current economic and market conditions, including Federal Reserve monetary policy expectations and the impact of legislative and regulatory changes. Additional factors that may significantly affect the estimates include, among others, competitive forces, customer behaviors and attrition, loan losses, changes in growth trends, cost structures and technology, changes in equity market values and merger and acquisition valuations, and changes in industry conditions.

Weakening in the economic environment, a decline in the performance of the reporting units, or other factors could cause the fair value of one or more of the reporting units to fall below carrying value, resulting in a goodwill impairment charge. Additionally, new legislative or regulatory changes not anticipated in management’s expectations may cause the fair value of one or more of the reporting units to fall below the carrying value, resulting in a goodwill impairment charge. Any impairment charge would not affect the Companys regulatory capital ratios, tangible common equity ratio, or liquidity position.

During the fourth quarter of 2015, we performed our annual goodwill impairment evaluation of the entire organization, effective October 1, 2015. Upon completion of the evaluation process, we concluded that none of our

82


Table of Contents

reporting units was impaired. Furthermore, the evaluation process determined that the fair values of Amegy, CB&T, and Zions Bank exceeded their carrying values by 14%, 45%, and 32%, respectively. Additionally, we performed a hypothetical sensitivity analysis on the discount rate assumption to evaluate the impact of an adverse change to this assumption. If the discount rate applied to future earnings were increased by 100 bps, the fair values of Amegy, CB&T, and Zions Bank would exceed their carrying values by 9%, 39%, and 16%, respectively. Additionally, because of the decline in energy prices since October 1, 2015 through December 31, 2015, we ran additional sensitivity analyses to estimate the impact that the decline would have on Amegy’s value and concluded that the goodwill of Amegy was not considered impaired during 2015.

However, due to the significant decline of energy prices in 2016 we are currently evaluating if the goodwill of Amegy is considered impaired for the first quarter of 2016. Our evaluation of impairment of goodwill balance at Amegy will consider the following key assumptions: the appropriate discount rate to reflect the uncertainty of achieving future cash flow projections, growth rate of the Texas economy, net loan loss expectations for future periods, stock prices of comparable publicly traded companies, and oil/gas forward price curves. These assumptions have been impacted by the decline in energy prices in 2016 and prolonged decline in energy prices can adversely impact the carrying value of Amegy. Note 9 of the Notes to Consolidated Financial Statements contains additional information related to goodwill.

Income Taxes
We are subject to the income tax laws of the United States, its states and other jurisdictions where we conduct business. These laws are complex and subject to different interpretations by the taxpayer and the various taxing authorities. In determining the provision for income taxes, management must make judgments and estimates about the application of these laws and related regulations. In the process of preparing the Company’s tax returns, management attempts to make reasonable interpretations of the tax laws. These interpretations are subject to challenge by the tax authorities upon audit or to reinterpretation based on management’s ongoing assessment of facts and evolving case law.
We had net DTAs of $203 million at December 31, 2015, compared to $224 million at December 31, 2014. The most significant portions of the deductible temporary differences relate to (1) the allowance for loan losses, (2) fair value adjustments or impairment write-downs related to securities, (3) pension and postretirement obligations and (4) deferred compensation arrangements. No valuation allowance has been recorded as of December 31, 2015 related to DTAs except for a full valuation reserve related to certain acquired net operating losses from an immaterial nonbank subsidiary. In assessing the need for a valuation allowance, both the positive and negative evidence about the realization of DTAs were evaluated. The ultimate realization of DTAs is based on the Company’s ability to (1) carry back net operating losses to prior tax periods, (2) utilize the reversal of taxable temporary differences to offset deductible temporary differences, (3) implement tax planning strategies that are prudent and feasible, and (4) generate future taxable income.
After considering the weight of the positive evidence compared to the negative evidence, management has concluded it is more likely than not that we will realize the existing DTAs and that an additional valuation allowance is not needed.
On a quarterly basis, management assesses the reasonableness of its effective tax rate based upon its current best estimate of net income and the applicable taxes expected for the full year. Deferred tax assets and liabilities are also reassessed on a regular basis. Reserves for contingent tax liabilities are reviewed quarterly for adequacy based upon developments in tax law and the status of examinations or audits. We have tax reserves at December 31, 2015 of approximately $4 million, net of federal and/or state benefits, primarily relating to uncertain tax positions for various state tax contingencies in several jurisdictions.
Note 14 of the Notes to Consolidated Financial Statements contains additional information regarding income taxes.

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

REPORT ON MANAGEMENT’S ASSESSMENT OF INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Zions Bancorporation and subsidiaries (“the Company”) is responsible for establishing and maintaining adequate internal control over financial reporting for the Company as defined by Exchange Act Rules 13a-15 and 15d-15.

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. Although any system of internal control can be compromised by human error or intentional circumvention of required procedures, we believe our system provides reasonable assurance that financial transactions are recorded and reported properly, providing an adequate basis for reliable financial statements.

The Company’s management has used the criteria established in Internal Control – Integrated Framework (2013 framework) issued by the COSO to evaluate the effectiveness of the Company’s internal control over financial reporting.

The Company’s management has assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2015 and has concluded that such internal control over financial reporting is effective. There are no material weaknesses in the Company’s internal control over financial reporting that have been identified by the Company’s management.

Ernst & Young LLP, an independent registered public accounting firm, has audited the consolidated financial statements of the Company for the year ended December 31, 2015 and has also issued an attestation report, which is included herein, on internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (“PCAOB”).

REPORTS OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
Audit Committee of the Board of Directors and Shareholders of Zions Bancorporation and Subsidiaries
We have audited Zions Bancorporation and subsidiaries internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Zions Bancorporation and subsidiaries management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Report on Managements Assessment of Internal Control over Financial Reporting. Our responsibility is to express an opinion on the companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys 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 companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys 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.

In our opinion, Zions Bancorporation and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Zions Bancorporation and subsidiaries as of December 31, 2015 and 2014 and the related consolidated statements of income, comprehensive income, changes in shareholders equity, and cash flows for each of the three years in the period ended December 31, 2015 of Zions Bancorporation and subsidiaries and our report dated February 29, 2016 expressed an unqualified opinion thereon.

REPORT ON CONSOLIDATED FINANCIAL STATEMENTS
Audit Committee of the Board of Directors and Shareholders of Zions Bancorporation and Subsidiaries

We have audited the accompanying consolidated balance sheets of Zions Bancorporation and subsidiaries as of December 31, 2015 and 2014, and the related consolidated statements of income, comprehensive income, changes in shareholders equity, and cash flows for each of the three years in the period ended December 31, 2015. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Zions Bancorporation and subsidiaries at December 31, 2015 and 2014, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2015, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Zions Bancorporation and subsidiaries internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 29, 2016 expressed an unqualified opinion thereon.

ZIONS BANCORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2015

1.
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Business
Zions Bancorporation (“the Parent”) is a financial holding company headquartered in Salt Lake City, Utah, which in 2015 provided a full range of banking and related services through seven subsidiary banks in 11 Western and Southwestern states as follows: Zions Bank, in Utah, Idaho and Wyoming; California Bank & Trust (“CB&T”); Amegy Bank, N. A. (“Amegy”), in Texas; National Bank of Arizona (“NBAZ”); Nevada State Bank (“NSB”); Vectra Bank Colorado, N.A. (“Vectra”), in Colorado and New Mexico; and The Commerce Bank of Washington (“TCBW”) which operates under that name in Washington and under the name The Commerce Bank of Oregon (“TCBO”) in Oregon. Pursuant to a Board resolution adopted November 21, 2014, The Commerce Bank of Oregon merged into TCBW effective March 31, 2015. The Parent also owns and operates certain nonbank subsidiaries that engage in financial services.

Following the close of business on December 31, 2015, these banks and certain of our subsidiaries of the Parent were merged into a single bank which was renamed ZB, N.A. The Parent intends to conduct its future banking business through locally managed and branded units corresponding to these seven banks.

Basis of Financial Statement Presentation
The consolidated financial statements include the accounts of the Parent and its majority-owned subsidiaries (“the Company,” “we,” “our,” “us”). Unconsolidated investments in which there is a greater than 20% ownership are accounted for by the equity method of accounting; those in which there is less than 20% ownership are accounted for under cost, fair value, or equity methods of accounting. All significant intercompany accounts and transactions have been eliminated in consolidation.

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and prevailing practices within the financial services industry. References to GAAP, including standards promulgated by the Financial Accounting Standards Board (“FASB”), are made according to sections of the Accounting Standards Codification (“ASC”). Changes to the ASC are made with Accounting Standards Updates (“ASU”) that include consensus issues of the Emerging Issues Task Force (“EITF”). In certain cases, ASUs are issued jointly with International Financial Reporting Standards (“IFRS”).

In preparing the consolidated financial statements, we are required to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Certain prior year amounts have been reclassified to conform with the current year presentation. These reclassifications did not affect net income or shareholders’ equity.

Variable Interest Entities
A variable interest entity (“VIE”) is consolidated when a company is the primary beneficiary of the VIE. Current accounting guidance requires continuous analysis on a qualitative rather than a quantitative basis to determine the primary beneficiary of a VIE. At the commencement of our involvement and periodically thereafter, we consider our consolidation conclusions for all entities with which we are involved. As of December 31, 2015 and 2014, no VIEs have been consolidated in the Company’s financial statements.

Statement of Cash Flows
For purposes of presentation in the consolidated statements of cash flows, “cash and cash equivalents” are defined as those amounts included in cash and due from banks in the consolidated balance sheets.

Security Resell Agreements
Security resell agreements represent overnight and term agreements with the majority maturing within 30 days. These agreements are generally treated as collateralized financing transactions and are carried at amounts at which the securities were acquired plus accrued interest. Either the Company, or in some instances third parties on its behalf, take possession of the underlying securities. The fair value of such securities is monitored throughout the contract term to ensure that asset values remain sufficient to protect against counterparty default. We are permitted by contract to sell or repledge certain securities that we accept as collateral for security resell agreements. If sold, our obligation to return the collateral is recorded as “securities sold, not yet purchased” and included as a liability in “Federal funds and other short-term borrowings.” At December 31, 2015, we held approximately $457 million of securities for which we were permitted by contract to sell or repledge. Security resell agreements averaged approximately $569 million during 2015, and the maximum amount outstanding at any month-end during 2015 was approximately $1.6 billion.

Investment Securities
We classify our investment securities according to their purpose and holding period. Gains or losses on the sale of securities are recognized using the specific identification method and recorded in noninterest income.

Held-to-maturity (“HTM”) debt securities are carried at amortized cost with purchase discounts or premiums accreted or amortized into interest income over the contractual life of the security. The Company has the intent and ability to hold such securities until maturity.

Available-for-sale (“AFS”) securities are stated at fair value and generally consist of debt securities held for investment and marketable equity securities not accounted for under the equity method. Unrealized gains and losses of AFS securities, after applicable taxes, are recorded as a component of other comprehensive income (“OCI”).

We review quarterly our investment securities portfolio for any declines in value that are considered to be other-than-temporary impairment (“OTTI”). The process, methodology and factors considered to evaluate securities for OTTI are discussed further in Note 5.

Trading securities are stated at fair value and consist of securities acquired for short-term appreciation or other trading purposes. Realized and unrealized gains and losses are recorded in trading income, which is included in capital markets and foreign exchange.

The fair values of investment securities, as estimated under current accounting guidance, are discussed in Note 20.

Loans and Allowance for Credit Losses
Loans are reported at the principal amount outstanding, net of unearned income. Unearned income, which includes deferred fees net of deferred direct loan origination costs, is amortized to interest income over the life of the loan using the interest method. Interest income is recognized on an accrual basis. Estimated prepayments are used in the determination of the amount of amortization.

At the time of origination, we determine whether loans will be held for investment or held for sale. We may subsequently change our intent to hold loans for investment and reclassify them as held for sale. Loans held for sale are carried at the lower of aggregate cost or fair value. A valuation allowance is recorded when cost exceeds fair value based on reviews at the time of reclassification and periodically thereafter. Gains and losses are recorded in noninterest income based on the difference between sales proceeds and carrying value.

Loans that become other than current with respect to contractual payments due may be accounted for separately depending on the status of the loan, which is determined from certain credit quality indicators and analysis under the circumstances. The loan status includes past due, nonaccrual, impaired, modified, and restructured (including

93


Table of Contents

troubled debt restructurings “TDRs”). Our accounting policies for these loan types and our estimation of the related allowance for loan losses are discussed further in Note 6.

In the ordinary course of business, we transfer portions of loans under participation agreements to manage credit risk and our portfolio concentration. We evaluate the loan participations to determine if they meet the appropriate accounting guidance to qualify as sales. Certain purchased loans require separate accounting procedures that are also discussed in Note 6.
The allowance for credit losses (“ACL”) includes the allowance for loan losses and the reserve for unfunded lending commitments, and represents our estimate of losses inherent in the loan portfolio that may be recognized from loans and lending commitments that are not recoverable. Further discussion of our estimation process for the ACL is included in Note 6.

Other Noninterest-Bearing Investments
These investments include investments in private equity funds (referred to in this document as private equity investments “PEIs”), venture capital securities, securities acquired for various debt and regulatory requirements, bank-owned life insurance, and certain other noninterest-bearing investments. See further discussions in Notes 5, 17 and 20.
Certain PEIs and venture capital securities are accounted for under the equity method and reported at estimated fair value in the absence of readily ascertainable fair values. Changes in fair value and gains and losses from sales are recognized in noninterest income. The values assigned to the securities where no market quotations exist are based upon available information and may not necessarily represent amounts that will ultimately be realized. Such estimated amounts depend on future circumstances and will not be realized until the individual securities are liquidated.
Bank-owned life insurance is accounted for at fair value based on the cash surrender values of the general account insurance policies. A third party service provides these values.
Other PEIs and those acquired for various debt and regulatory requirements are accounted for at cost. Periodic reviews are conducted for impairment by comparing carrying values with estimates of fair value determined according to the previous discussion.

Premises and Equipment
Premises and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation, computed primarily on the straight-line method, is charged to operations over the estimated useful lives of the properties, generally 25 to 40 years for buildings, 3 to 10 years for furniture and equipment, and 3 to 10 years for software, including capitalized costs related to the Company’s new lending and deposit systems. Leasehold improvements are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter.

Goodwill and Identifiable Intangible Assets
Goodwill and intangible assets deemed to have indefinite lives are not amortized. We subject these assets to annual specified impairment tests as of the beginning of the fourth quarter and more frequently if changing conditions warrant. Core deposit assets and other intangibles with finite useful lives are generally amortized on an accelerated basis using an estimated useful life of up to 12 years.

Business Combinations
Business combinations are accounted for under the acquisition method of accounting. Upon initially obtaining control, we recognize 100% of all acquired assets and all assumed liabilities regardless of the percentage owned. The assets and liabilities are recorded at their estimated fair values, with goodwill being recorded when such fair values are less than the cost of acquisition. Certain transaction and restructuring costs are expensed as incurred.

94


Table of Contents

Changes to estimated fair values from a business combination are recognized as an adjustment to goodwill over the measurement period, which cannot exceed one year from the acquisition date. Results of operations of the acquired business are included in our statement of income from the date of acquisition.

Other Real Estate Owned
Other real estate owned (“OREO”) consists principally of commercial and residential real estate obtained in partial or total satisfaction of loan obligations. Amounts are recorded initially at fair value (less any selling costs) based on property appraisals at the time of transfer and subsequently at the lower of cost or fair value (less any selling costs).

Derivative Instruments
We use derivative instruments, including interest rate swaps and floors and basis swaps, as part of our overall interest rate risk management strategy. These instruments enable us to manage to desired asset and liability duration and to reduce interest rate risk exposure by matching estimated repricing periods of interest-sensitive assets and liabilities. We also execute derivative instruments with commercial banking customers to facilitate their risk management strategies. These derivatives are immediately hedged by offsetting derivatives with third parties such that we minimize our net risk exposure as a result of such transactions. We record all derivatives at fair value in the balance sheet as either other assets or other liabilities. See further discussion in Note 7.

Commitments and Letters of Credit
In the ordinary course of business, we enter into commitments to extend credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded in the financial statements when they become payable. The credit risk associated with these commitments is evaluated in a manner similar to the allowance for loan losses. The RULC is presented separately in the balance sheet.

Revenue Recognition
Service charges and fees on deposit accounts are recognized in accordance with published deposit account agreements for customer accounts or contractual agreements for commercial accounts. Other service charges, commissions and fees include interchange fees, bank services, and other fees which are generally recognized when earned.

Share-Based Compensation
Share-based compensation generally includes grants of stock options, restricted stock, restricted stock units, and other awards to employees and nonemployee directors. We recognize compensation expense in the statement of income based on the fair value of the associated share-based awards. See further discussion in Note 16.

Income Taxes
Deferred tax assets and liabilities are determined based on temporary differences between financial statement asset and liability amounts and their respective tax bases, and are measured using enacted tax laws and rates. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are recognized subject to management’s judgment that realization is more likely than not. Unrecognized tax benefits for uncertain tax positions relate primarily to state tax contingencies. See further discussion in Note 14.

Net Earnings Per Common Share
Net earnings per common share is based on net earnings applicable to common shareholders, which is net of preferred stock dividends. Basic net earnings per common share is based on the weighted average outstanding common shares during each year. Unvested share-based awards with rights to receive nonforfeitable dividends are considered participating securities and included in the computation of basic earnings per share. Diluted net earnings per common share is based on the weighted average outstanding common shares during each year, including common stock equivalents. Stock options, restricted stock, restricted stock units, and stock warrants are converted

95

to common stock equivalents using the treasury method. Diluted net earnings per common share excludes common stock equivalents whose effect is antidilutive. See further discussion in Note 15.

Standards not yet adopted by the Company
 
 
 
 
 
 
 
ASU 2016-02,
Leases (Topic 842)
 
The standard requires that a lessee recognize assets and liabilities for leases with lease terms of more than 12 months. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, the standard will require both types of leases to be recognized on the balance sheet. It also requires disclosures to better understand the amount, timing, and uncertainty of cash flows arising from leases. These disclosures include qualitative and quantitative requirements, providing additional information about the amounts recorded in the financial statements.
 
January 1, 2019
 
We are currently evaluating the potential impact of this new guidance on the Company’s financial statements.
 
 
 
 
 
 
 
ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities
 
The standard provides revised accounting guidance related to the accounting for and reporting of financial instruments. Some of the main provisions include:
 Equity investments that do not result in consolidation and are not accounted for under the equity method would be measured at fair value through net income, unless they qualify for the proposed practicability exception for investments that do not have readily determinable fair values.
 Changes in instrument-specific credit risk for financial liabilities that are measured under the fair value option would be recognized in other comprehensive income.
 Elimination of the requirement to disclose the methods and significant assumptions used to estimate the fair value of financial instruments carried at amortized cost. However it will require the use of exit price when measuring the fair value of financial instruments measured at amortized cost for disclosure purposes.
 
January 1, 2018
 
We do not currently expect this new guidance will have a material impact on the Company’s financial statements.
 
 
 
 
 
 
 
ASU 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or its Equivalent), (Topic 820)
 
The guidance eliminates the current requirement to categorize within the fair value hierarchy investments whose fair values are measured at net asset value (“NAV”) using the practical expedient in ASC 820. Fair value disclosure of these investments will be made to facilitate reconciliation to amounts reported on the balance sheet. Other related disclosures will continue when the NAV practical expedient is used. Adoption is retrospective and early adoption is permitted.
 
January 1, 2016
 
We do not expect this new disclosure guidance will have a material impact on the Company’s financial statements.
 
 
 
 
 
 
 
ASU 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement (Subtopic 350-40)
 
The standard provides guidance to determine whether an arrangement includes a software license. If it does, the customer accounts for it the same way as for other software licenses. If no software license is included, the customer accounts for it as a service contract. Adoption may be retrospective or prospective. Early adoption is permitted.
 
January 1, 2016
 
We do not expect this new guidance will have a material impact on the Company’s financial statements.
 
ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs (Subtopic 835-30)
 
The standard requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the associated debt liability, consistent with debt discounts. Adoption is retrospective and early adoption is permitted.
 
January 1, 2016
 
We currently include debt issuance costs in other assets. The amount to be reclassified to the debt liability is not material to the Company’s financial statements.

ASU 2015-02, Amendments to the Consolidation Analysis (Topic 810)
 
The new standard changes certain criteria in the variable interest model and the voting model to determine whether certain legal entities are variable interest entities (“VIEs”) and whether they should be consolidated. Additional disclosures are required for entities not currently considered VIEs, but may become VIEs under the new guidance and may be subject to consolidation. Adoption may be retrospective or modified retrospective with a cumulative effect adjustment. Early adoption is permitted.
 
January 1, 2016
 
We currently do not consolidate any VIEs and do not expect this new guidance will have a material impact on the Company’s financial statements.
 
 
 
 
 
 
 
ASU 2014-09, Revenue from Contracts with Customers (Topic 606)
 
The core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The banking industry does not expect significant changes because major sources of revenue are from financial instruments that have been excluded from the scope of the new standard, (including loans, derivatives, debt and equity securities, etc.). However, the new standard affects other fees charged by banks, such as asset management fees, credit card interchange fees, deposit account fees, etc. Adoption may be made on a full retrospective basis with practical expedients, or on a modified retrospective basis with a cumulative effect adjustment. Early adoption of the guidance is permitted as of January 1, 2017.
 
January 1, 2018, as extended in August 2015 by ASU 2015-14
 
While we currently do not expect this standard will have a material impact on the Company’s financial statements, we are still in process of conducting our evaluation.
 
 
 
 
 
 
 
Standards adopted by the Company
 
 
 
 
 
 
 
ASU 2014-14, Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure (Subtopic 310-40)
 
The standard addresses the classification of certain foreclosed mortgage loans fully or partially guaranteed under government programs. Under certain such programs, qualifying creditors can extend mortgage loans with a guarantee entitling the creditor to recover all or a portion of the unpaid principal balance from the government if the borrower defaults. A separate other receivable is established that is measured based on the amount of the loans expected to be recovered.
 
January 1, 2015
 
Our adoption of this standard had no impact on the accompanying financial statements.
 
 
 
 
 
 
 
ASU 2014-04, Reclassification of Residential Real Estate Collateralized
Consumer Mortgage Loans upon Foreclosure (Subtopic 310-40)
 
The standard clarifies that a creditor should be considered to have physical possession of a residential real estate property collateralizing a residential mortgage loan and thus would reclassify the loan to other real estate owned when certain conditions are satisfied. Additional financial statement disclosures will be required.
 
January 1, 2015
 
Our adoption of this standard added a nominal amount of additional disclosure to Note 6.
 
 
 
 
 
 
 
ASU 2014-01, Accounting for Investments in Qualified Affordable Housing
Projects (Topic 323)
 
The standard revised conditions an entity must meet to elect the effective yield method when accounting for qualified affordable housing project investments. The EITF final consensus changed the method of amortizing a Low-Income Housing Tax Credit (“LIHTC”) investment from the effective yield method to a proportional amortization method. Amortization would be proportional to the tax credits and tax benefits received but, under a practical expedient available in certain circumstances, amortization could be proportional to only the tax credits. Reporting entities that invest in LIHTC investments through a limited liability entity could elect the proportional amortization method if certain conditions are met.
 
January 1, 2015
 
Our adoption of this standard did not have a material impact on the accompanying financial statements.

The gross unrealized losses recognized in OCI on HTM securities resulted from a previous transfer of AFS securities to HTM and from OTTI.

CDO Sales and Paydowns
During the second quarter of 2015, we sold the remaining portfolio of our collateralized debt obligation (“CDO”) securities, or $574 million at amortized cost, and realized net losses of approximately $137 million. During the first quarter of 2015, we reclassified all of the remaining held-to-maturity CDO securities, or approximately $79 million at amortized cost, to AFS securities. The reclassification resulted from increased risk weights for these securities under the new Basel III capital rules, and was made in accordance with applicable accounting guidance that allows for such reclassifications when increased risk weights of debt securities must be used for regulatory risk-based capital purposes. No gain or loss was recognized in the statement of income at the time of reclassification.

During 2014, we reduced the CDO portfolio by $1.02 billion amortized cost through sales and paydowns/payoffs which resulted in net fixed income securities gains of $10.4 million. These sales were made in part as a result of the Volcker Rule (“VR”).

At December 31, 2015 and 2014, respectively, 187 and 153 HTM and 709 and 458 AFS investment securities were in an unrealized loss position.
Other-Than-Temporary Impairment
Ongoing Policy
We review investment securities on a quarterly basis for the presence of other-than-temporary impairment (“OTTI”). We assess whether OTTI is present when the fair value of a debt security is less than its amortized cost basis at the balance sheet date (the majority of the investment portfolio are debt securities). Under these circumstances, OTTI is considered to have occurred if (1) we have formed a documented intent to sell identified securities or initiated such sales; (2) it is “more likely than not” we will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not sufficient to recover the entire amortized cost basis.

Noncredit-related OTTI in securities we intend to sell is recognized in earnings as is any credit-related OTTI in securities, regardless of our intent. Noncredit-related OTTI on AFS securities not expected to be sold is recognized in OCI. The amount of noncredit-related OTTI in a security is quantified as the difference in a security’s amortized cost after adjustment for credit impairment, and its lower fair value. Presentation of OTTI is made in the statement of income on a gross basis with an offset for the amount of OTTI recognized in OCI.

Our OTTI evaluation process takes into consideration current market conditions; fair value in relationship to cost; extent and nature of change in fair value; severity and duration of the impairment; recent events specific to the issuer or industry; our assessment of the creditworthiness of the issuer, including external credit ratings, changes, recent downgrades, and trends; the cash flow priority position of the instrument that we hold in the case of structured securities; volatility of earnings and trends; current analysts’ evaluations; all available information relevant to the collectability of debt securities; and other key measures. In addition, for AFS securities with fair values below amortized cost, we must determine if we intend to sell the securities or if it is more likely than not that we will be required to sell the securities before recovery of their amortized cost basis. For HTM securities, we must

determine we have the ability to hold the securities to maturity. We consider any other relevant factors before concluding our evaluation for the existence of OTTI in our securities portfolio.

OTTI Conclusions
The following summarizes the conclusions from our OTTI evaluation for those security types that had significant gross unrealized losses at December 31, 2015:

OTTI U.S. Government Agencies and Corporations
Agency Securities: These securities were issued by the Federal Agricultural Mortgage Corporation (“FAMC”) and the Export-Import Bank of the U.S. These securities are fixed or floating-rate and were generally purchased at par. They have maturity dates from 1 to 25 years and have contractual cash flows guaranteed by agencies of the U.S. Government. Unrealized losses relate to changes in interest rates subsequent to purchase and are not attributable to credit. At December 31, 2015, we did not have an intent to sell identified securities with unrealized losses or initiate such sales, and we believe it is more likely than not we would not be required to sell such securities before recovery of their amortized cost basis. Therefore, we did not record OTTI for these securities during 2015.

Agency Guaranteed Mortgage-Backed Securities: These pass-through securities are comprised largely of fixed and floating-rate residential mortgage-backed securities issued by the Government National Mortgage Association (“GNMA”), the Federal National Mortgage Association (“FNMA”), or the Federal Home Loan Mortgage Corporation (“FHLMC”). They were generally purchased at premiums with maturity dates from 10 to 15 years for fixed-rate securities and 30 years for floating-rate securities. These securities benefit from certain guarantee provisions or, in the case of GNMA, direct U.S. government guarantees. Unrealized losses relate to changes in interest rates subsequent to purchase and are not attributable to credit. At December 31, 2015, we did not have an intent to sell identified securities with unrealized losses or initiate such sales, and we believe it is more likely than not we would not be required to sell such securities before recovery of their amortized cost basis. Therefore, we did not record OTTI for these securities during 2015.

Small Business Administration (“SBA”) Loan-Backed Securities: These securities were generally purchased at premiums with maturities from 5 to 25 years and have principal cash flows guaranteed by the SBA. Unrealized losses relate to changes in interest rates subsequent to purchase and are not attributable to credit. At December 31, 2015, we did not have an intent to sell identified SBA securities with unrealized losses or initiate such sales, and we believe it is more likely than not we would not be required to sell such securities before recovery of their amortized cost basis. Therefore, we did not record OTTI for these securities during 2015.

To determine the credit component of OTTI for all security types, we utilize projected cash flows. These cash flows are credit adjusted using, among other things, assumptions for default probability and loss severity. Certain other unobservable inputs such as prepayment rate assumptions are also utilized. In addition, certain internal models may be utilized. See Note 20 for further discussion. To determine the credit-related portion of OTTI in accordance with applicable accounting guidance, we use the security specific effective interest rate when estimating the present value of cash flows.

Investment securities with a carrying value of approximately $2.3 billion and $1.4 billion at December 31, 2015 and 2014, respectively, were pledged to secure public and trust deposits, advances, and for other purposes as required by law. Securities are also pledged as collateral for security repurchase agreements.

Private Equity Investments
Effect of Volcker Rule
The VR, as published pursuant to the Dodd-Frank Act in December 2013 and amended in January 2014, significantly restricted certain activities by covered bank holding companies, including restrictions on certain types of securities, proprietary trading, and private equity investing. The Company’s PEIs consist of Small Business Investment Companies (“SBICs”) and non-SBICs. Following the sales of its CDO securities, the only prohibited investments under the VR requiring divestiture by the Company were certain of its PEIs. Of the recorded PEIs of $137 million at December 31, 2015, approximately $18 million remain prohibited by the VR.

As of December 31, 2015, we have sold a total of approximately $17 million of PEIs, including $9 million during 2015 and $8 million during 2014. All of these sales related to prohibited PEIs. The 2015 sales resulted in insignificant amounts of realized gains or losses. The 2014 sales resulted in net realized gains of $5.6 million, of which $5.1 million was recorded in equity securities gains and $0.5 million was recorded in dividends and other investment income. Further, we recognized $4.7 million of net impairment in 2014 on prohibited PEIs. The remaining balance of PEIs are primarily recorded at estimated fair value at December 31, 2015.

We will dispose of the remaining $18 million of prohibited PEIs before the required deadline. However, the required deadline has been extended to July 21, 2016 from July 21, 2015 and the Federal Reserve has announced its intention

105


Table of Contents

to grant banking entities an additional one-year extension to July 21, 2017. See other discussions in Notes 17 and 20.

As discussed in Note 17, we have $22 million at December 31, 2015 of unfunded commitments for PEIs, of which approximately $7 million relate to prohibited PEIs. Until we dispose of the prohibited PEIs, we expect to fund these commitments if and as capital calls are made, as allowed under the VR.

Loan balances are presented net of unearned income and fees, which amounted to $150.3 million at December 31, 2015 and $144.7 million at December 31, 2014.
Owner occupied and commercial real estate (“CRE”) loans include unamortized premiums of approximately $26.2 million at December 31, 2015 and $36.5 million at December 31, 2014.
Municipal loans generally include loans to municipalities with the debt service being repaid from general funds or pledged revenues of the municipal entity, or to private commercial entities or 501(c)(3) not-for-profit entities utilizing a pass-through municipal entity to achieve favorable tax treatment.
Land development loans included in the construction and land development loan class were $288.0 million at December 31, 2015, and $484.9 million at December 31, 2014.
Loans with a carrying value of approximately $19.4 billion at December 31, 2015 and $22.5 billion at December 31, 2014 have been pledged at the Federal Reserve and various Federal Home Loan Banks (“FHLBs”) as collateral for potential borrowings.
We sold loans totaling $1.4 billion in 2015, $1.2 billion in 2014, and $1.6 billion in 2013, that were classified as loans held for sale. The sold loans were derecognized from the balance sheet. Loans classified as loans held for sale primarily consist of conforming residential mortgages and the guaranteed portion of SBA loans. The principal balance of sold loans for which we retain servicing was approximately $1.3 billion at December 31, 2015 and 2014.
Amounts added to loans held for sale during these years were $1.4 billion, $1.2 billion, and $1.5 billion, respectively. Income from loans sold, excluding servicing, was $17.8 million in 2015, $15.1 million in 2014, and $24.1 million in 2013.

During the third quarter of 2014, construction and land development loans decreased by $447 million due to conversions to term loans, and increased syndication and participation arrangements. Additionally, 1-4 family residential loans increased by $326 million, primarily due to the purchase of $249 million par amount of high quality jumbo adjustable rate mortgage (“ARM”) loans from another bank. Management took these actions to improve the risk profile of the Company’s loans and reduce portfolio concentration risk.

Since 2009, CB&T and NSB have had loss-sharing agreements with the Federal Deposit Insurance Corporation (“FDIC”), which provided indemnification for credit losses of acquired loans and foreclosed assets up to specified thresholds. The agreements for commercial loans, which comprised the major portion of the acquired portfolio, expired as of September 30, 2014. The agreements for 1-4 family residential loans will expire in 2019. In previous periods, the FDIC-supported loan balances were presented separately in this footnote and in other disclosures, and included purchased credit-impaired (“PCI”) loans as subsequently discussed in Purchased Loans. Due to declining balances, for all years presented herein, the FDIC-supported/PCI loans have been reclassified to their respective loan segments and classes.
Allowance for Credit Losses
The allowance for credit losses (“ACL”) consists of the allowance for loan and lease losses (“ALLL”) (also referred to as the allowance for loan losses) and the RULC.

Allowance for Loan and Lease Losses
The ALLL represents our estimate of probable and estimable losses inherent in the loan and lease portfolio as of the balance sheet date. Losses are charged to the ALLL when recognized. Generally, commercial loans are charged off or charged down at the point at which they are determined to be uncollectible in whole or in part, or when 180 days past due, unless the loan is well secured and in the process of collection. Consumer loans are either charged off or charged down to net realizable value no later than the month in which they become 180 days past due. Closed-end loans that are not secured by residential real estate are either charged off or charged down to net realizable value no later than the month in which they become 120 days past due. We establish the amount of the ALLL by analyzing the portfolio at least quarterly, and we adjust the provision for loan losses so the ALLL is at an appropriate level at the balance sheet date.
We determine our ALLL as the best estimate within a range of estimated losses. The methodologies we use to estimate the ALLL depend upon the impairment status and portfolio segment of the loan. The methodology for impaired loans is discussed subsequently. For the commercial and CRE segments, we use a comprehensive loan grading system to assign probability of default (“PD”) and loss given default (“LGD”) grades to each loan. The credit quality indicators discussed subsequently are based on this grading system. In addition, loan officers utilize their experience and judgment in assigning PD and LGD grades, subject to confirmation of the PD and LGD by either credit risk or credit examination. We create groupings of these grades for each banking affiliate and loan class and calculate historic loss rates using a loss migration analysis that attributes historic realized losses to these loan grade groupings over the period of January 2008 through the most recent full quarter.

For the consumer loan segment, we use roll rate models to forecast probable inherent losses. Roll rate models measure the rate at which consumer loans migrate from one delinquency category to the next worse delinquency category, and eventually to loss. We estimate roll rates for consumer loans using recent delinquency and loss experience by segmenting our consumer loan portfolio into separate pools based on common risk characteristics and separately calculating historical delinquency and loss experience for each pool. These roll rates are then applied to current delinquency levels to estimate probable inherent losses. Roll rates incorporate housing market trends inasmuch as these trends manifest themselves in charge-offs and delinquencies. In addition, our qualitative and environmental factors discussed subsequently incorporate the most recent housing market trends.

The current status and historical changes in qualitative and environmental factors may not be reflected in our quantitative models. Thus, after applying historical loss experience, as described above, we review the quantitatively derived level of ALLL for each segment using qualitative criteria and use those criteria to determine

our estimate within the range. We track various risk factors that influence our judgment regarding the level of the ALLL across the portfolio segments. These factors primarily include:
Asset quality trends
Risk management and loan administration practices
Risk identification practices
Effect of changes in the nature and volume of the portfolio
Existence and effect of any portfolio concentrations
National economic and business conditions
Regional and local economic and business conditions
Data availability and applicability
Effects of other external factors
The magnitude of the impact of these factors on our qualitative assessment of the ALLL changes from quarter to quarter according to the extent these factors are already reflected in historic loss rates and according to the extent these factors diverge from one to another. We also consider the uncertainty inherent in the estimation process when evaluating the ALLL.
Reserve for Unfunded Lending Commitments
We also estimate a reserve for potential losses associated with off-balance sheet commitments, including standby letters of credit. We determine the RULC using the same procedures and methodologies that we use for the ALLL. The loss factors used in the RULC are the same as the loss factors used in the ALLL, and the qualitative adjustments used in the RULC are the same as the qualitative adjustments used in the ALLL. We adjust the Company’s unfunded lending commitments that are not unconditionally cancelable to an outstanding amount equivalent using credit conversion factors, and we apply the loss factors to the outstanding equivalents.

Nonaccrual and Past Due Loans
Loans are generally placed on nonaccrual status when payment in full of principal and interest is not expected, or the loan is 90 days or more past due as to principal or interest, unless the loan is both well secured and in the process of collection. Factors we consider in determining whether a loan is placed on nonaccrual include delinquency status, collateral value, borrower or guarantor financial statement information, bankruptcy status, and other information which would indicate that the full and timely collection of interest and principal is uncertain.
A nonaccrual loan may be returned to accrual status when all delinquent interest and principal become current in accordance with the terms of the loan agreement; the loan, if secured, is well secured; the borrower has paid according to the contractual terms for a minimum of six months; and analysis of the borrower indicates a reasonable assurance of the ability and willingness to maintain payments. Payments received on nonaccrual loans are applied as a reduction to the principal outstanding.
Closed-end loans with payments scheduled monthly are reported as past due when the borrower is in arrears for two or more monthly payments. Similarly, open-end credit such as charge-card plans and other revolving credit plans are reported as past due when the minimum payment has not been made for two or more billing cycles. Other multi-payment obligations (i.e., quarterly, semiannual, etc.), single payment, and demand notes are reported as past due when either principal or interest is due and unpaid for a period of 30 days or more.

Represents nonaccrual loans not past due more than 30 days; however, full payment of principal and interest is still not expected.
Credit Quality Indicators
In addition to the past due and nonaccrual criteria, we also analyze loans using loan risk grading systems, which vary based on the size and type of credit risk exposure. The internal risk grades assigned to loans follow our definitions of Pass, Special Mention, Substandard, and Doubtful, which are consistent with published definitions of regulatory risk classifications.
Definitions of Pass, Special Mention, Substandard, and Doubtful are summarized as follows:
Pass – A Pass asset is higher quality and does not fit any of the other categories described below. The likelihood of loss is considered remote.
Special Mention – A Special Mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the bank’s credit position at some future date.
Substandard – A Substandard asset is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified have well-defined weaknesses and are characterized by the distinct possibility that the bank may sustain some loss if deficiencies are not corrected.
Doubtful – A Doubtful asset has all the weaknesses inherent in a Substandard asset with the added characteristics that the weaknesses make collection or liquidation in full highly questionable.
We generally assign internal risk grades to commercial and CRE loans with commitments equal to or greater than $750,000 based on financial and statistical models, individual credit analysis, and loan officer judgment. For these larger loans, we assign one of multiple grades within the Pass classification or one of the following four grades: Special Mention, Substandard, Doubtful, and Loss. Loss indicates that the outstanding balance has been charged off. We confirm our internal risk grades quarterly, or as soon as we identify information that affects the credit risk of the loan.

Table of Contents

For consumer loans or certain small commercial loans with commitments equal to or less than $750,000, we generally assign internal risk grades similar to those described previously based on automated rules that depend on refreshed credit scores, payment performance, and other risk indicators. These are generally assigned either a Pass or Substandard grade and are reviewed as we identify information that might warrant a grade change.
Outstanding loan balances (accruing and nonaccruing) categorized by these credit quality indicators are summarized as follows:

Impaired Loans
Loans are considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due in accordance with the contractual terms of the loan agreement, including scheduled interest payments. For our non-purchased credit-impaired loans, if a nonaccrual loan has a balance greater than $1 million, or if a loan is a TDR, including TDRs that subsequently default, or if the loan is no longer reported as a TDR, we individually evaluate the loan for impairment and estimate a specific reserve for the loan for all portfolio segments under applicable accounting guidance. Smaller nonaccrual loans are pooled for ALLL estimation purposes. PCI loans are included in impaired loans and are accounted for under separate accounting guidance. See subsequent discussion under Purchased Loans.

When a loan is impaired, we estimate a specific reserve for the loan based on the projected present value of the loan’s future cash flows discounted at the loan’s effective interest rate, the observable market price of the loan, or the fair value of the loan’s underlying collateral. The process of estimating future cash flows also incorporates the same determining factors discussed previously under nonaccrual loans. When we base the impairment amount on the fair value of the loan’s underlying collateral, we generally charge-off the portion of the balance that is impaired, such that these loans do not have a specific reserve in the ALLL. Payments received on impaired loans that are accruing are recognized in interest income, according to the contractual loan agreement. Payments received on impaired loans that are on nonaccrual are not recognized in interest income, but are applied as a reduction to the principal outstanding. The amount of interest income recognized on a cash basis during the time the loans were impaired within the years ended December 31, 2015 and 2014 was not significant.
Information on all impaired loans is summarized as follows, including the average recorded investment and interest income recognized for the years ended December 31, 2015 and 2014:

Modified and Restructured Loans
Loans may be modified in the normal course of business for competitive reasons or to strengthen the Company’s position. Loan modifications and restructurings may also occur when the borrower experiences financial difficulty and needs temporary or permanent relief from the original contractual terms of the loan. These modifications are structured on a loan-by-loan basis and, depending on the circumstances, may include extended payment terms, a modified interest rate, forgiveness of principal, or other concessions. Loans that have been modified to accommodate a borrower who is experiencing financial difficulties, and for which the Company has granted a concession that it would not otherwise consider, are considered TDRs.
We consider many factors in determining whether to agree to a loan modification involving concessions, and seek a solution that will both minimize potential loss to the Company and attempt to help the borrower. We evaluate borrowers’ current and forecasted future cash flows, their ability and willingness to make current contractual or proposed modified payments, the value of the underlying collateral (if applicable), the possibility of obtaining additional security or guarantees, and the potential costs related to a repossession or foreclosure and the subsequent sale of the collateral.
TDRs are classified as either accrual or nonaccrual loans. A loan on nonaccrual and restructured as a TDR will remain on nonaccrual status until the borrower has proven the ability to perform under the modified structure for a minimum of six months, and there is evidence that such payments can and are likely to continue as agreed. Performance prior to the restructuring, or significant events that coincide with the restructuring, are included in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual at the time of restructuring or after a shorter performance period. If the borrower’s ability to meet the revised payment schedule is uncertain, the loan remains classified as a nonaccrual loan. A TDR loan that specifies an interest rate that at the time of the restructuring is greater than or equal to the rate the bank is willing to accept for a new loan with comparable risk may not be reported as a TDR or an impaired loan in the calendar years subsequent to the restructuring if it is in compliance with its modified terms.

As of December 31, 2015, the amount of foreclosed residential real estate property held by the Company was approximately $0.5 million, and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure was approximately $12.5 million.

Concentrations of Credit Risk
Credit risk is the possibility of loss from the failure of a borrower, guarantor, or another obligor to fully perform under the terms of a credit-related contract. Credit risks (whether on- or off-balance sheet) may occur when individual borrowers, groups of borrowers, or counterparties have similar economic characteristics, including industries, geographies, collateral types, sponsors, etc., and are similarly affected by changes in economic or other conditions. Credit risk also includes the loss that would be recognized subsequent to the reporting date if counterparties failed to perform as contracted. See Note 7 for a discussion of counterparty risk associated with the Company’s derivative transactions.

We perform an ongoing analysis of our loan portfolio to evaluate whether there is any significant exposure to any concentrations of credit risk. Based on this analysis, we believe that the loan portfolio is generally well diversified; however, due to the nature of the Company’s geographical footprint, there are certain significant concentrations primarily in CRE and oil and gas-related lending. Further, we cannot guarantee that we have fully understood or mitigated all risk concentrations or correlated risks. We have adopted and adhere to concentration limits on various types of CRE lending, particularly construction and land development lending, leveraged lending, municipal lending, and oil and gas-related lending. All of these limits are continually monitored and revised as we judge appropriate. These concentration limits, particularly the various types of CRE and real estate development loan limits, are materially lower than they were just prior to the emergence of the recent economic downturn.

Purchased Loans
Background and Accounting
We purchase loans in the ordinary course of business and account for them and the related interest income based on their performing status at the time of acquisition. Purchased credit-impaired (“PCI”) loans have evidence of credit deterioration at the time of acquisition and it is probable that not all contractual payments will be collected. Interest income for PCI loans is accounted for on an expected cash flow basis. Certain other loans acquired by the Company that are not credit-impaired include loans with revolving privileges and are excluded from the PCI tabular disclosures following. Interest income for these loans is accounted for on a contractual cash flow basis. Certain acquired loans with similar characteristics such as risk exposure, type, size, etc., are grouped and accounted for in loan pools.
Outstanding Balances and Accretable Yield

At the time of acquisition of PCI loans, we determine the loan’s contractually required payments in excess of all cash flows expected to be collected as an amount that should not be accreted (nonaccretable difference). With

Table of Contents

respect to the cash flows expected to be collected, the portion representing the excess of the loan’s expected cash flows over our initial investment (accretable yield) is accreted into interest income on a level yield basis over the remaining expected life of the loan or pool of loans. The effects of estimated prepayments are considered in estimating the expected cash flows.

Certain PCI loans are not accounted for as previously described because the estimation of cash flows to be collected involves a high degree of uncertainty. Under these circumstances, the accounting guidance provides that interest income is recognized on a cash basis similar to the cost recovery methodology for nonaccrual loans. The net carrying amounts in the preceding schedule also include the amounts for these loans. There were no amounts of these loans at December 31, 2015 and $5.3 million at December 31, 2014.

The primary drivers of reclassification to accretable yield from nonaccretable difference and increases in disposals and other were (1) changes in estimated cash flows, (2) unexpected payments on nonaccrual loans, and (3) recoveries on zero balance loans pools. See subsequent discussion under changes in cash flow estimates.
ALLL Determination
For all acquired loans, the ALLL is only established for credit deterioration subsequent to the date of acquisition and represents our estimate of the inherent losses in excess of the book value of acquired loans. The ALLL for acquired loans is included in the overall ALLL in the balance sheet.
During 2015, 2014 and 2013, we adjusted the ALLL for acquired loans by recording a provision for loan losses of $0.3 million in 2015, and a negative provision of $(1.7) million in 2014, and $(10.1) million in 2013. The provision is net of the ALLL reversals resulting from changes in cash flow estimates, which are discussed subsequently.
Changes in the provision for loan losses and related ALLL are driven in large part by the same factors that affect the changes in reclassification from nonaccretable difference to accretable yield, as discussed under changes in cash flow estimates.
Changes in Cash Flow Estimates
Over the life of the loan or loan pool, we continue to estimate cash flows expected to be collected. We evaluate quarterly at the balance sheet date whether the estimated present values of these loans using the effective interest rates have decreased below their carrying values. If so, we record a provision for loan losses.

For increases in carrying values that resulted from better than expected cash flows, we use such increases first to reverse any existing ALLL. During 2015, 2014, and 2013, total reversals to the ALLL, including the impact of increases in estimated cash flows, were $3.7 million in 2015 and $4.6 million in 2014, and $15.1 million in 2013. When there is no current ALLL, we increase the amount of accretable yield on a prospective basis over the remaining life of the loan and recognize this increase in interest income.
The impact of increased cash flow estimates recognized in the statement of income for acquired loans with no ALLL was approximately $31.6 million in 2015, $46.7 million in 2014, and $90.9 million in 2013, of additional interest income.

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
Objectives
Our objectives in using derivatives are to add stability to interest income or expense, to modify the duration of specific assets or liabilities as we consider advisable, to manage exposure to interest rate movements or other identified risks, and/or to directly offset derivatives sold to our customers. We apply hedge accounting to certain derivatives executed for risk management purposes as described in more detail subsequently. However, we do not apply hedge accounting to all of the derivatives involved in our risk management activities. Derivatives not designated as accounting hedges are not speculative and are used to economically manage our exposure to interest rate movements and other identified risks, but do not meet the strict hedge accounting requirements.

Accounting
We record all derivatives on the balance sheet at fair value. Note 20 discusses the process to estimate fair value for derivatives. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected cash flows, or other types of forecasted transactions, are considered cash flow hedges.
For derivatives designated as fair value hedges, changes in the fair value of the derivative are recognized in earnings together with changes in the fair value of the related hedged item. The net amount, if any, representing hedge ineffectiveness, is reflected in earnings. In previous years, we used fair value hedges to manage interest rate exposure to certain long-term debt. These hedges have been terminated and their remaining balances were completely amortized into earnings during 2015.
For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative are recorded in OCI and recognized in earnings when the hedged transaction affects earnings. The ineffective portion of changes in the fair value of cash flow hedges is recognized directly in earnings. We use interest rate swaps as part of our cash flow hedging strategy to hedge the variable cash flows associated with designated commercial loans. These interest rate swap agreements designated as cash flow hedges involve the receipt of fixed-rate amounts in exchange for variable-rate payments over the life of the agreements without exchange of the underlying notional amount.

No derivatives have been designated for hedges of investments in foreign operations.
We assess the effectiveness of each hedging relationship by comparing the changes in fair value or cash flows on the derivative hedging instrument with the changes in fair value or cash flows on the designated hedged item or transaction. For derivatives not designated as accounting hedges, changes in fair value are recognized in earnings.
The remaining balances of any derivative instruments terminated prior to maturity, including amounts in accumulated other comprehensive income (“AOCI”) for swap hedges, are accreted or amortized to interest income or expense over the period to their previously stated maturity dates.
Amounts in AOCI are reclassified to interest income as interest is earned on variable-rate loans and as amounts for terminated hedges are accreted or amortized to earnings. For the 12 months following December 31, 2015, we estimate that an additional $6.0 million will be reclassified.

Collateral and Credit Risk
Exposure to credit risk arises from the possibility of nonperformance by counterparties. Financial institutions which are well capitalized and well established are the counterparties for those derivatives entered into for asset liability management and to offset derivatives sold to our customers. The Company reduces its counterparty exposure for derivative contracts by centrally clearing all eligible derivatives.

121


Table of Contents

For those derivatives that are not centrally cleared, the counterparties are typically financial institutions or customers of the Company. For those that are financial institutions, we manage our credit exposure through the use of a Credit Support Annex (“CSA”) to International Swaps and Derivative Association (“ISDA”) master agreements. Eligible collateral types are documented by the CSA and controlled under the Company’s general credit policies. They are typically monitored on a daily basis. A valuation haircut policy reflects the fact that collateral may fall in value between the date the collateral is called and the date of liquidation or enforcement. In practice, all of the Company’s collateral held as credit risk mitigation under a CSA is cash.
We offer interest rate swaps to our customers to assist them in managing their exposure to changing interest rates. Upon issuance, all of these customer swaps are immediately offset through matching derivative contracts, such that the Company minimizes its interest rate risk exposure resulting from such transactions. Most of these customers do not have the capability for centralized clearing. Therefore we manage the credit risk through loan underwriting which includes a credit risk exposure formula for the swap, the same collateral and guarantee protection applicable to the loan and credit approvals, limits, and monitoring procedures. Fee income from customer swaps is included in other service charges, commissions and fees. No significant losses on derivative instruments have occurred as a result of counterparty nonperformance. Nevertheless, the related credit risk is considered and measured when and where appropriate. See Note 6 and 17 for further discussion of our underwriting, collateral requirements, and other procedures used to address credit risk.

Our derivative contracts require us to pledge collateral for derivatives that are in a net liability position at a given balance sheet date. Certain of these derivative contracts contain credit-risk-related contingent features that include the requirement to maintain a minimum debt credit rating. We may be required to pledge additional collateral if a credit-risk-related feature were triggered, such as a downgrade of our credit rating. However, in past situations, not all counterparties have demanded that additional collateral be pledged when provided for under their contracts. At December 31, 2015, the fair value of our derivative liabilities was $72.6 million, for which we were required to pledge cash collateral of approximately $56.6 million in the normal course of business. If our credit rating were downgraded one notch by either Standard & Poor’s or Moody’s at December 31, 2015, the additional amount of collateral we could be required to pledge is approximately $1.6 million. As a result of the Dodd-Frank Act, all newly eligible derivatives entered into are cleared through a central clearinghouse. Derivatives that are centrally cleared do not have credit-risk-related features that require additional collateral if our credit rating were downgraded.

Amounts of $9.0 million for 2015 and $2.6 million for 2014 are the amounts of reclassification to earnings presented in the tabular changes of AOCI in Note 13.
The fair value of derivative assets was reduced by a net credit valuation adjustment of $2.4 million at both December 31, 2015 and 2014. The adjustment for derivative liabilities was not significant at December 31, 2015 and 2014. These adjustments are required to reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk.

Federal funds purchased and security repurchase agreements generally mature in less than 30 days. Our participation in security repurchase agreements is on an overnight or term basis (e.g., 30 or 60 days). Our subsidiary bank executes overnight repurchase agreements with sweep accounts in conjunction with a master repurchase agreement. When this occurs, securities under their control are pledged and interest is paid on the collected balance of the customers’ accounts. For term repurchase agreements, securities are transferred to the applicable counterparty. The counterparty, in certain instances, is contractually entitled to sell or repledge securities accepted as collateral. Of the total security repurchase agreements at December 31, 2015, $63 million were overnight and $143 million were term.

Prior to the consolidation of our subsidiary bank charters on December 31, 2015, the subsidiary banks could borrow from the FHLB under their lines of credit that are secured under blanket pledge arrangements. The subsidiary banks maintained unencumbered collateral with carrying amounts adjusted for the types of collateral pledged, equal to at least 100% of the outstanding advances. At December 31, 2015, the amount available for FHLB advances was approximately $9.1 billion and no short-term FHLB advances were outstanding.

Additionally, prior to the consolidation of our subsidiary bank charters on December 31, 2015, the subsidiary banks could also borrow from the Federal Reserve based on the amount of collateral pledged to a Federal Reserve Bank. At December 31, 2015, the amount available for additional Federal Reserve borrowings was approximately $4.3 billion.

Designation of “3mL” is three-month LIBOR; effective interest rate at the beginning of the accrual period commencing on or before December 31, 2015 is shown in parenthesis.

The junior subordinated debentures for the Amegy and Stockmen’s Trusts were assumed by the Parent through previous acquisitions and mergers, and are direct and unsecured obligations of the Parent. They are subordinate to other indebtedness and general creditors.

The Parent has assumed the unconditional guarantees of the obligations of the Amegy and Stockmen’s trusts with respect to their respective series of trust preferred securities to the extent set forth in the applicable guarantee agreements. Each trust has issued a corresponding series of trust preferred security obligations. The trust obligations are in the form of capital securities subject to mandatory redemption upon repayment of the junior subordinated debentures by the Parent. The sole assets of the trusts are the junior subordinated debentures.

Interest distributions are made quarterly at the same rates earned by the trusts on the junior subordinated debentures; however, we may defer the payment of interest on the junior subordinated debentures. Early redemption is currently possible on all of the debentures and requires the approval of banking regulators.

SHAREHOLDERS’ EQUITY
Preferred Stock
Preferred stock is without par value and has a liquidation preference of $1,000 per share, or $25 per depositary share. Except for Series I and J, all preferred shares were issued in the form of depositary shares, with each depositary share representing a 1/40th ownership interest in a share of the preferred stock. All preferred shares are registered with the SEC.

In general, preferred shareholders may receive asset distributions before common shareholders; however, preferred shareholders have only limited voting rights generally with respect to certain provisions of the preferred stock, the issuance of senior preferred stock, and the election of directors. Preferred stock dividends reduce earnings available to common shareholders and are paid on the 15th day of the months indicated in the following schedule. Dividends are approved by the Board of Directors and are subject to regulatory non-objection to a stress test and capital plan submitted to the Federal Reserve pursuant to the annual Comprehensive Capital Analysis and Review (“CCAR”) process. Redemption of the preferred stock is at the Company’s option after the expiration of any applicable redemption restrictions. The redemption amount is computed at the per share liquidation preference plus any declared but unpaid dividends. Redemptions are subject to certain regulatory provisions, including the previously noted capital plan non-objection for a submitted capital plan in a given year.

Preferred Stock Redemptions
Effective November 18, 2015, we redeemed approximately $175.7 million of Series I preferred stock through a cash tender offer. The offer amount of $180 million, or $24.65 per share, differed from the redemption amount by approximately $4.3 million of accrued dividends. The size and terms of the offer were determined in accordance with the Company’s 2015 capital plan.

In September 2013, we redeemed all of the outstanding $800 million par amount of Series C preferred stock through the issuance of an aggregate equivalent amount of other series of preferred stock. The reduction of $926 million carrying value in preferred stock differed from the par amount by $126 million, which was the intrinsic value of the beneficial conversion feature (“BCF”) associated with the convertible subordinated debt. The BCF had been accumulating as the convertible subordinated debt was converted to the Series C preferred stock. The $126 million BCF transfer was recorded as a preferred stock redemption in the 2013 statement of income. As shown in Note 12, the remaining convertible subordinated debt matured during 2015.

Common Stock
In July 2014, we issued $525 million of common stock, which consisted of approximately 17.6 million shares at a price of $29.80 per share. Net of commissions and fees, this issuance added approximately $516 million to common stock and was permitted under the Company’s resubmitted capital plan.

Common Stock Warrants
We have 5.8 million common stock warrants at an exercise price of $36.27 per share which expire November 14, 2018. These warrants were associated with the preferred stock issued under the Troubled Asset Relief Program (“TARP”) which was redeemed in 2012. In addition, we have issued a total of 29.3 million common stock warrants which can be exercised at a price of $36.14 as of December 31, 2015 through May 22, 2020.

Deferred Compensation
Deferred compensation consists of invested assets, including the Company’s common stock, which are held in rabbi trusts for certain employees and directors. At December 31, 2015 and 2014, the cost of the common stock included in retained earnings was approximately $15.2 million and $14.3 million, respectively. We consolidate the fair value of invested assets of the trusts along with the total obligations and include them in other assets and other liabilities, respectively, in the balance sheet. At December 31, 2015 and 2014, total invested assets were approximately $81.8 million and $86.6 million and total obligations were approximately $96.9 million and $100.9 million, respectively.

Noncontrolling Interests
In 2013, we removed the entire noncontrolling interest amount of approximately $4.8 million from the Company’s balance sheet following settlement with the remaining owner.

The amount of net DTAs is included with other assets in the balance sheet. The $4.3 million valuation allowance at December 31, 2015 and 2014 was for certain acquired net operating loss carryforwards included in our acquisition of the remaining interests in a less significant subsidiary. At December 31, 2015, excluding the $4.3 million, the tax effect of remaining net operating loss and tax credit carryforwards was approximately $0.4 million expiring through 2030.

We evaluate the net DTAs on a regular basis to determine whether an additional valuation allowance is required. In conducting this evaluation, we have considered all available evidence, both positive and negative, based on the more likely than not criteria that such assets will be realized. This evaluation includes, but is not limited to: (1) available carryback potential to prior tax years; (2) potential future reversals of existing deferred tax liabilities, which historically have a reversal pattern generally consistent with DTAs; (3) potential tax planning strategies; and (4) future projected taxable income. Based on this evaluation, and considering the weight of the positive evidence compared to the negative evidence, we have concluded that an additional valuation allowance is not required as of December 31, 2015.

We have a liability for unrecognized tax benefits relating to uncertain tax positions primarily for various state tax contingencies in several jurisdictions. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows:

At December 31, 2015 and 2014, the liability for unrecognized tax benefits included approximately $3.9 million and $2.1 million, respectively (net of the federal tax benefit on state issues) that, if recognized, would affect the effective tax rate. There is approximately $3.3 million of gross unrecognized tax benefits that may decrease during the 12 months subsequent to December 31, 2015.

Interest and penalties related to unrecognized tax benefits are included in income tax expense in the statement of income. At December 31, 2015 and 2014, accrued interest and penalties recognized in the balance sheet, net of any federal and/or state tax benefits, were approximately $0.7 million and $0.6 million, respectively.

The Company and its subsidiaries file income tax returns in U.S. federal and various state jurisdictions. The Company is no longer subject to income tax examinations for years prior to 2012 for federal returns and 2007 for certain state returns.

SHARE-BASED COMPENSATION
We have a stock option and incentive plan which allows us to grant stock options, restricted stock, restricted stock units (“RSUs”), and other awards to employees and nonemployee directors. Total shares authorized under the plan were 9,000,000 at December 31, 2015, of which 7,523,768 were available for future grants.

All share-based payments to employees, including grants of employee stock options, are recognized in the statement of income based on their fair values. The fair value of an equity award is estimated on the grant date without regard to service or performance vesting conditions.

We classify all share-based awards as equity instruments. Compensation expense is included in salaries and employee benefits in the statement of income, with the corresponding increase included in common stock. Substantially all awards of stock options, restricted stock, and RSUs have graded vesting that is recognized on a straight-line basis over the vesting period.

Compensation expense and the related tax benefit for all share-based awards were as follows:

As of December 31, 2015, compensation expense not yet recognized for nonvested share-based awards was approximately $26.6 million, which is expected to be recognized over a weighted average period of 2.4 years.

The tax effects recognized from the exercise of stock options and the vesting of restricted stock and RSUs decreased common stock by approximately $0.8 million in 2015, and increased common stock by approximately $0.4 million in 2014, and $0.3 million in 2013. These amounts are included in the net activity under employee plans and related tax benefits in the statement of changes in shareholders’ equity.

Stock Options
Stock options granted to employees generally vest at the rate of one third each year and expire seven years after the date of grant. For all stock options granted in 2015, 2014, and 2013, we used the Black-Scholes option pricing model to estimate the fair values of stock options in determining compensation expense. The following summarizes the weighted average of fair value and the significant assumptions used in applying the Black-Scholes model for options granted:

The weighted average remaining contractual life excludes 21,252 stock options without a fixed expiration date that were assumed with the Amegy acquisition. They expire between the date of termination and one year from the date of termination, depending upon certain circumstances.

Table of Contents

The aggregate intrinsic value of outstanding stock options at December 31, 2015 and 2014 was $8.0 million and $14.4 million, respectively, while the aggregate intrinsic value of exercisable options was $8.0 million and $11.3 million at the same respective dates. For exercisable options, the weighted average remaining contractual life was 3.1 years and 1.8 years at December 31, 2015 and 2014, respectively, excluding the stock options previously noted without a fixed expiration date. At December 31, 2015, 1,579,501 stock options with a weighted average exercise price of $28.59, a weighted average remaining life of 5.6 years, and an aggregate intrinsic value of $27.3 thousand, were expected to vest.

Restricted Stock and Restricted Stock Units
Restricted stock is common stock with certain restrictions that relate to trading and the possibility of forfeiture. Generally, restricted stock vests over four years. Holders of restricted stock have full voting rights and receive dividend equivalents during the vesting period. In addition, holders of restricted stock can make an election to be subject to income tax on the grant date rather than the vesting date.

RSUs represent rights to one share of common stock for each unit and generally vest over four years. Holders of RSUs receive dividend equivalents during the vesting period, but do not have voting rights.

Compensation expense is determined based on the number of restricted shares or RSUs granted and the market price of our common stock at the issue date.

Nonemployee directors were granted 31,080 RSUs in 2015; 16,670 shares of restricted stock and 6,656 RSUs in 2014; and 17,444 shares of restricted stock and 4,984 RSUs in 2013. The 2015 RSUs vested immediately upon grant, and the 2014 and 2013 awards vested over six months.

COMMITMENTS, GUARANTEES, CONTINGENT LIABILITIES, AND RELATED PARTIES
Commitments and Guarantees
We use certain financial instruments, including derivative instruments, in the normal course of business to meet the financing needs of our customers, to reduce our own exposure to fluctuations in interest rates, and to make a market in U.S. Government, agency, corporate, and municipal securities. These financial instruments involve, to varying degrees, elements of credit, liquidity, and interest rate risk in excess of the amounts recognized in the balance sheet. Derivative instruments are discussed in Notes 7 and 20.

Contractual amounts of the off-balance sheet financial instruments used to meet the financing needs of our customers are as follows:

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee. The amount of collateral obtained, if deemed necessary by us upon extension of

137


Table of Contents

credit, is based on our initial credit evaluation of the counterparty. Types of collateral vary, but may include accounts receivable, inventory, property, plant and equipment, and income-producing properties.

While establishing commitments to extend credit creates credit risk, a significant portion of such commitments is expected to expire without being drawn upon. As of December 31, 2015, $4.9 billion of commitments expire in 2016. We use the same credit policies and procedures in making commitments to extend credit and conditional obligations as we do for on-balance sheet instruments. These policies and procedures include credit approvals, limits, and monitoring.

We issue standby and commercial letters of credit as conditional commitments generally to guarantee the performance of a customer to a third party. The guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions. Standby letters of credit include remaining commitments of $684 million expiring in 2016 and $195 million expiring thereafter through 2027. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. We generally hold marketable securities and cash equivalents as collateral when necessary. At December 31, 2015, the Company recorded $5.3 million as a liability for these guarantees, which consisted of $2.2 million attributable to the RULC and $3.1 million of deferred commitment fees.

Certain mortgage loans sold have limited recourse provisions for periods ranging from three months to one year. The amount of losses resulting from the exercise of these provisions has not been significant.

At December 31, 2015, we had unfunded commitments for PEIs of approximately $22 million. These obligations have no stated maturity. Approximately $7 million of the PEIs related to these commitments are prohibited by the VR. See related discussions about these investments in Notes 5 and 20.

The contractual or notional amount of financial instruments indicates a level of activity associated with a particular financial instrument class and is not a reflection of the actual level of risk. As of December 31, 2015 and 2014, the regulatory risk-weighted values assigned to all off-balance sheet financial instruments and derivative instruments described herein were $6.3 billion and $5.9 billion, respectively.

At December 31, 2015, we were required to maintain cash balances of $295.2 million with the Federal Reserve Banks to meet minimum balance requirements in accordance with Federal Reserve Board (“FRB”) regulations.

As of December 31, 2015, the Parent has guaranteed approximately $165 million of debt of affiliated trusts issuing trust preferred securities, as discussed in Note 12.

Leases
We have commitments for leasing premises and equipment under the terms of noncancelable capital and operating leases expiring from 2016 and 2052. Premises leased under capital leases at December 31, 2015, were $1.2 million and accumulated amortization was $0.9 million. Amortization applicable to premises leased under capital leases is included in depreciation expense.

Aggregate rental expense on operating leases amounted to $62.5 million in 2015, $59.2 million in 2014, and $58.4 million in 2013.

Legal Matters
We are subject to litigation in court and arbitral proceedings, as well as proceedings, investigations, examinations and other actions brought or considered by governmental and self-regulatory agencies. Litigation may relate to lending, deposit and other customer relationships, vendor and contractual issues, employee matters, intellectual property matters, personal injuries and torts, regulatory and legal compliance, and other matters. While most matters relate to individual claims, we are also subject to putative class action claims and similar broader claims. Proceedings, investigations, examinations and other actions brought or considered by governmental and self-regulatory agencies may relate to our banking, investment advisory, trust, securities, and other products and services; our customers’ involvement in money laundering, fraud, securities violations and other illicit activities or our policies and practices relating to such customer activities; and our compliance with the broad range of banking, securities and other laws and regulations applicable to us. At any given time, we may be in the process of responding to subpoenas, requests for documents, data and testimony relating to such matters and engaging in discussions to resolve the matters.
As of December 31, 2015, we were subject to the following material litigation and governmental inquiries:
a class action case, Reyes v. Zions First National Bank, et. al., which was brought in the United States District Court for the Eastern District of Pennsylvania in early 2010. This case relates to our banking relationships with customers that allegedly engaged in wrongful telemarketing practices. The plaintiff is seeking a trebled monetary award under the federal RICO Act. In the third quarter of 2013, the District Court denied the plaintiff’s motion for class certification in the Reyes case. The plaintiff appealed the District Court decision to the Third Circuit Court of Appeals. In the third quarter of 2015, the Third Circuit vacated the District Court’s decision denying class certification and remanded the matter to the District Court with instructions to reconsider the class certification determination in light of particular standards articulated by the Third Circuit in its opinion. Following the Third Circuit’s decision, the parties participated in mediation sessions in the fourth quarter of 2015 and the first quarter of 2016. We do not know whether these discussions will result in a settlement.
a governmental inquiry into possible money laundering activities of one of our bank customers and our anti-money laundering practices relating to that customer (conducted by the United States Attorney’s Office for the Southern District of New York). Our first contact with the United States Attorney’s Office relating to this matter occurred in early 2012. We are unclear about the status of this inquiry.
a governmental inquiry into our payment processing practices relating primarily to certain allegedly fraudulent telemarketers and other customer types (conducted by the Department of Justice). Similar inquiries directed towards banks unrelated to us have resulted in a number of enforcement actions. Our first contact with the

139


Table of Contents

Department of Justice relating to this matter occurred in early 2013. It appears that the Department of Justice’s inquiry into our practice is continuing.
a civil suit, Liu Aifang, et al. v. Velocity VIII, et al., brought against us in the United States District Court for the Central District of California in April 2015. The case relates to our banking relationships with customers who were approved promoters of an EB-5 Visa Immigrant Investment Program that allegedly misappropriated investors’ funds. On September 30, 2015, the Court granted in part and denied in part our Motion to Dismiss Plaintiffs’ claims.  The Plaintiffs’ remaining claims assert negligence and that the bank aided and abetted the promoter customers’ conversion of the investors’ funds deposited with us. Discovery is ongoing and trial is scheduled for June 2016.

At least quarterly, we review outstanding and new legal matters, utilizing then available information. In accordance with applicable accounting guidance, if we determine that a loss from a matter is probable and the amount of the loss can be reasonably estimated, we establish an accrual for the loss. In the absence of such a determination, no accrual is made. Once established, accruals are adjusted to reflect developments relating to the matters.

In our review, we also assess whether we can determine the range of reasonably possible losses for significant matters in which we are unable to determine that the likelihood of a loss is remote. Because of the difficulty of predicting the outcome of legal matters, discussed subsequently, we are able to meaningfully estimate such a range only for a limited number of matters. Based on information available as of December 31, 2015, we estimated that the aggregate range of reasonably possible losses for those matters to be from $0 million to roughly $60 million in excess of amounts accrued. The matters underlying the estimated range will change from time to time, and actual results may vary significantly from this estimate. Those matters for which a meaningful estimate is not possible are not included within this estimated range and, therefore, this estimated range does not represent our maximum loss exposure.

Based on our current knowledge, we believe that our current estimated liability for litigation and other legal actions and claims, reflected in our accruals and determined in accordance with applicable accounting guidance, is adequate and that liabilities in excess of the amounts currently accrued, if any, arising from litigation and other legal actions and claims for which an estimate as previously described is possible, will not have a material impact on our financial condition, results of operations, or cash flows. However, in light of the significant uncertainties involved in these matters, and the very large or indeterminate damages sought in some of these matters, an adverse outcome in one or more of these matters could be material to our financial condition, results of operations, or cash flows for any given reporting period.
Any estimate or determination relating to the future resolution of litigation, arbitration, governmental or self-regulatory examinations, investigations or actions or similar matters is inherently uncertain and involves significant judgment. This is particularly true in the early stages of a legal matter, when legal issues and facts have not been well articulated, reviewed, analyzed, and vetted through discovery, preparation for trial or hearings, substantive and productive mediation or settlement discussions, or other actions. It is also particularly true with respect to class action and similar claims involving multiple defendants, matters with complex procedural requirements or substantive issues or novel legal theories, and examinations, investigations and other actions conducted or brought by governmental and self-regulatory agencies, in which the normal adjudicative process is not applicable. Accordingly, we usually are unable to determine whether a favorable or unfavorable outcome is remote, reasonably likely, or probable, or to estimate the amount or range of a probable or reasonably likely loss, until relatively late in the course of a legal matter, sometimes not until a number of years have elapsed. Accordingly, our judgments and estimates relating to claims will change from time to time in light of developments and actual outcomes will differ from our estimates. These differences may be material.

Related Party Transactions
We have no material related party transactions requiring disclosure. In the ordinary course of business, the Company and its subsidiary bank extend credit to related parties, including executive officers, directors, principal

140

shareholders, and their associates and related interests. These related party loans are made in compliance with applicable banking regulations.

18.
REGULATORY MATTERS
We are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory – and possibly additional discretionary – actions by regulators that, if undertaken, could have a direct material effect on our financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that involve quantitative measures of our assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Required capital levels are also subject to judgmental review by regulators.

The Basel III capital rules, which effectively replaced the Basel I rules, became effective for the Company on January 1, 2015 (subject to phase-in periods for certain of their components). In 2013, the FRB, FDIC, and OCC published final rules (the “Basel III Capital Rules”) establishing a new comprehensive capital framework for U.S. banking organizations. The rules implement the Basel Committee’s December 2010 framework, commonly referred to as Basel III, for strengthening international capital standards as well as certain provisions of the Dodd-Frank Act. The Basel III capital rules substantially revised the risk-based capital requirements applicable to bank holding companies and depository institutions, including the Company, compared to the Basel I U.S. risk-based capital rules.

Under prior Basel I capital standards, the effects of AOCI items included in capital were excluded for purposes of determining regulatory capital and capital ratios. As a “non-advanced approaches banking organization,” we made a one-time permanent election as of January 1, 2015 to continue to exclude these items, as allowed under the Basel III Capital Rules.

Quantitative measures established by regulation to ensure capital adequacy require us to maintain minimum amounts and ratios (set forth in the following schedule) of Total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). As of December 31, 2015, all capital ratios of the Company and its subsidiary bank exceeded the “well-capitalized” levels under the regulatory framework for prompt corrective action. Dividends declared by our subsidiary bank in any calendar year may not, without the approval of the appropriate federal regulators, exceed specified criteria.

Appropriate capital levels and distributions of capital to shareholders for the Company and other “systemically important financial institutions” (“SIFIs”) are also subject to annual “stress tests” performed as a part of the Federal Reserve’s CCAR process.

The stress tests seek to comprehensively measure all risks to which the institution is exposed, including credit, liquidity, market, operating and other risks, the losses that could result from those risk exposures under adverse scenarios, and the institution’s resulting capital levels. These stress tests have both a qualitative and a quantitative component. The qualitative component evaluates the robustness of the Company’s risk identification, stress risk modeling, policies, capital planning, governance processes, and other components of a Capital Adequacy Process. The quantitative process subjects the Company’s balance sheet and other risk characteristics to stress testing and independent determination by the Federal Reserve using its own models. Most capital actions, including for example, payment of dividends and repurchasing stock, are subject to non-objection by the Federal Reserve to a capital plan based on both the qualitative and quantitative assessments of the plan.

Because the Company’s subsidiary bank has assets greater than $10 billion also it is subject to annual stress testing and capital planning processes examined by the Office of the Comptroller of the Currency (“OCC”), known as the Dodd-Frank Act Stress Test (“DFAST”).

There is no Tier 1 leverage ratio component in the definition of a well-capitalized bank holding company.

Zions is also subject to “capital conservation buffer” regulatory requirements. When fully phased-in on January 1, 2019, the Basel III Capital Rules will require the Company and its subsidiary bank to maintain a 2.5% capital conservation buffer, designed to absorb losses during periods of economic stress, composed entirely of CET1, on top of the minimum risk-weighted asset ratios, effectively resulting in minimum ratios of (i) CET1 to risk-weighted assets of at least 7%, (ii) Tier 1 capital to risk-weighted assets of at least 8.5%, and (iii) Total capital to risk-weighted assets of at least 10.5%. Banking institutions with a ratio of CET1 to risk-weighted assets above the minimum but below the capital conservation buffer will face constraints on dividends, equity repurchases, and compensation. The implementation of the buffer will be phased-in beginning January 1, 2016 at the 0.625% level

142


Table of Contents

and increase by 0.625% on each subsequent January 1, until it reaches 2.5% on January 1, 2019. Zions’ triggers and limits under actual conditions and baseline projections are more restrictive than the capital conservation buffer
requirements.

RETIREMENT PLANS
Defined Benefit Plans
Pension – This qualified noncontributory defined benefit plan has been frozen to new participation. No service-related benefits accrued for existing participants except for those with certain grandfathering provisions. Effective July 1, 2013, the plan was amended to remove the exception for grandfathered participants. The effect of this change was not significant to the plan. All participants in the Plan are currently 100% vested in their benefits. Plan assets consist principally of corporate equity securities, mutual fund investments, real estate, and fixed income investments. Plan benefits are paid as a lump-sum cash value or an annuity at retirement age. Contributions to the plan are based on actuarial recommendation and pension regulations. Currently, it is expected that no minimum regulatory contributions will be required in 2016.

Supplemental Retirement These unfunded nonqualified plans are for certain current and former employees. Each year, Company contributions to these plans are made in amounts sufficient to meet benefit payments to plan participants.

Postretirement Medical/Life This unfunded health care and life insurance plan provides postretirement medical benefits to certain full-time employees who meet minimum age and service requirements. The plan also provides specified life insurance benefits to certain employees. The plan is contributory with retiree contributions adjusted annually, and contains other cost-sharing features such as deductibles and coinsurance. Plan coverage is provided by self-funding or health maintenance organization options. Our contribution towards the retiree medical premium has been permanently frozen at an amount that does not increase in any future year. Retirees pay the difference between the full premium rates and our capped contribution.

Because our contribution rate is capped, there is no effect on the postretirement plan from assumed increases or decreases in health care cost trends. Each year, Company contributions to the plan are made in amounts sufficient to meet the portion of the premiums that are the Company’s responsibility.

For 2015, the pension plan benefit obligation at end of year decreased due to the updated mortality table issued by the Society of Actuaries that reflects increased life expectancy assumptions, and an increase in the year-end discount rate. The liability for pension/postretirement benefits is included in other liabilities in the balance sheet. The accumulated benefit obligation is the same as the benefit obligation shown in the preceding schedule.

The amounts in AOCI (loss) at December 31, 2015 expected to be recognized as an expense component of net periodic benefit cost in 2016 for the plans are estimated as follows:

As previously discussed, the pension plan became fully frozen effective July 1, 2013 by a plan amendment that eliminated the remaining grandfather provisions. This action eliminated the need to continue using the rate of compensation increase assumption as of December 31, 2013.

The discount rate reflects the yields available on long-term, high-quality fixed income debt instruments with cash flows similar to the obligations of the pension plan, and is reset annually on the measurement date. The expected long-term rate of return on plan assets is based on a review of the target asset allocation of the plan. This rate is intended to approximate the long-term rate of return that we anticipate receiving on the plan’s investments, considering the mix of the assets that the plan holds as investments, the expected return on these underlying investments, the diversification of these investments, and the rebalancing strategies employed. An expected long-term rate of return is assumed for each asset class and an underlying inflation rate assumption is determined.

Benefit payments to the plans’ participants are estimated as follows for the years succeeding December 31, 2015:

We are also obligated under other supplemental retirement plans for certain current and former employees. Our liability for these plans was $6.9 million and $6.3 million at December 31, 2015 and 2014, respectively.

For the pension plan, the investment strategy is predicated on its investment objectives and the risk and return expectations of asset classes appropriate for the plan. Investment objectives have been established by considering the plan’s liquidity needs and time horizon and the fiduciary standards under the Employee Retirement Income Security Act of 1974. The asset allocation strategy is developed to meet the plan’s long-term needs in a manner designed to control volatility and to reflect risk tolerance. Target investment allocation percentages as of December 31, 2015 are 65% in equity, 30% in fixed income and cash, and 5% in real estate assets.

No transfers of assets occurred among Levels 1, 2 or 3 during 2015 or 2014.

The following describes the pension plan investments and the valuation methodologies used to measure their fair value:

Company common stock – Shares of the Company’s common stock are valued at the last reported sales price on the last business day of the plan year in the active market where individual securities are traded.

Mutual funds – These funds are valued at quoted market prices which represent the NAVs of shares held by the plan at year-end.

Insurance company pooled separate accounts – These funds are invested in by more than one investor. They are offered through separate accounts of the trustee’s insurance company and managed by internal and professional advisors. Participation units in these accounts are valued at the NAV as the practical expedient for fair value as determined by the insurance company.

Guaranteed deposit account – This account is a group annuity product issued by the trustee’s insurance company with guaranteed crediting rates established at the beginning of each calendar year. The account balance is stated at fair value as estimated by the trustee. The account is credited with deposits made, plus earnings at guaranteed crediting rates, less withdrawals and administrative expenses. The underlying investments generally include investment-grade public and privately traded debt securities, mortgage loans and, to a lesser extent, real estate and other equity investments. Market value adjustments are applied at the time of redemption if certain withdrawal limits are exceeded.

The Company’s Benefits Committee evaluates the methodology and factors used, including review of the contract, economic conditions, industry and market developments, and overall credit ratings of the underlying investments.

Limited partnerships – These partnerships invest in limited partnerships, limited liability companies, or similar investment vehicles that consist of PEIs in a wide variety of investment types, including venture and growth capital, real estate, energy and natural resources, and other private investments. The plan’s investments are valued by the limited partnerships at NAV as the practical expedient for fair value. The estimation process takes into account the plan’s proportional interests credited with realized and unrealized earnings from the underlying investments and charged for operating expenses and distributions. Investments are increased by capital calls and are part of an overall capital commitment by the plan of up to approximately $8.75 million at December 31, 2015.

The following presents additional information as of December 31, 2015 and 2014 for the pooled separate accounts and limited partnerships whose fair values under Levels 2 and 3 are based on NAV per share:

Shares of Company common stock were 233,849 and 262,209 at December 31, 2015 and 2014, respectively. Dividends received by the plan were approximately $56 thousand in 2015 and $43 thousand in 2014.

Defined Contribution Plan
The Company offers a 401(k) and employee stock ownership plan under which employees select from several investment alternatives. Employees can contribute up to 80% of their earnings subject to the annual maximum allowed contribution. The Company matches 100% of the first 3% of employee contributions and 50% of the next 2% of employee contributions. Matching contributions to participants, which were shares of the Company’s common stock purchased in the open market, amounted to $25.5 million in 2015, $24.3 million in 2014, and $22.7 million in 2013.

The 401(k) plan also has a noncontributory profit sharing feature which is discretionary and may range from 0% to 6% of eligible compensation based upon the Company’s return on average common equity for the year. The profit sharing expense was computed at a contribution rate of 1% for 2015 and 2% for 2014 and 2013, and amounted to $6.1 million for 2015, $12.0 million for 2014 and $11.8 million for 2013. The profit sharing contribution to participants consisted of shares of the Company’s common stock purchased in the open market.

FAIR VALUE
Fair Value Measurement
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. To measure fair value, a hierarchy has been established that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs. This hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows:
Level 1 – Quoted prices in active markets for identical assets or liabilities in active markets that the Company has the ability to access;

148


Table of Contents

Level 2 – Observable inputs other than Level 1 including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in less active markets, observable inputs other than quoted prices that are used in the valuation of an asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means; and
Level 3 – Unobservable inputs supported by little or no market activity for financial instruments whose value is determined by pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.
The level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measure in its entirety. Market activity is presumed to be orderly in the absence of evidence of forced or disorderly sales, although such sales may still be indicative of fair value. Applicable accounting guidance precludes the use of blockage factors or liquidity adjustments due to the quantity of securities held by an entity.

We use fair value to measure certain assets and liabilities on a recurring basis when fair value is the primary measure for accounting. Fair value is used on a nonrecurring basis to measure certain assets when adjusting carrying values, such as the application of lower of cost or fair value accounting, including recognition of impairment on assets. Fair value is also used when providing required disclosures for certain financial instruments.

Fair Value Policies and Procedures
We have various policies, processes and controls in place to ensure that fair values are reasonably developed, reviewed and approved for use. These include a Securities Valuation Committee (“SVC”) comprised of executive management appointed by the Board of Directors. The SVC reviews and approves on a quarterly basis the key components of fair value estimation, including critical valuation assumptions for Level 3 modeling. A Model Risk Management Group conducts model validations, including internal models, and sets policies and procedures for revalidation, including the timing of revalidation.

Third Party Service Providers
We use a third party pricing service to fair value measurements for approximately 92% of our AFS Level 2 securities. Fair value measurements for other AFS Level 2 generally use certain inputs corroborated by market data and include standard form discounted cash flow modeling.

For Level 2 securities, the third party pricing service provides documentation on an ongoing basis that presents market corroborative data, including detail pricing information and market reference data. The documentation includes benchmark yields, reported trades, broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data, including information from the vendor trading platform. We review, test and validate this information as appropriate. Absent observable trade data, we do not adjust prices from our third party sources.

The following describes the hierarchy designations, valuation methodologies, and key inputs to measure fair value on a recurring basis for designated financial instruments:

Available-for-Sale
U.S. Treasury, Agencies and Corporations
U.S. Treasury securities are measured under Level 1 using quoted market prices when available. U.S. agencies and corporations are measured under Level 2 generally using the previously discussed third party pricing service.

Municipal Securities
Municipal securities are measured under Level 2 generally using the third party pricing service or an internal model. Valuation inputs include Baa municipal curves, as well as FHLB and London Interbank Offered Rate

149


Table of Contents

(“LIBOR”) swap curves. Our valuation methodology for non-rated municipal securities changed at year end to utilize more observable inputs, primarily municipal market yield curves, and fewer unobservable inputs as compared to our previous valuation method. The resulting values were determined to be Level 2.
Money Market Mutual Funds and Other
Money market mutual funds and other securities are measured under Level 1 or Level 2. For Level 1, quoted market prices are used which may include NAVs or their equivalents. Level 2 valuations generally use quoted prices for similar securities.

Trading Account
Securities in the trading account are generally measured under Level 2 using third party pricing service providers as described previously.
Bank-Owned Life Insurance
Bank-owned life insurance (“BOLI”) is measured under Level 2 according to cash surrender values (“CSVs”) of the insurance policies that are provided by a third party service. Nearly all policies are general account policies with CSVs based on the Company’s claims on the assets of the insurance companies. The insurance companies’ investments include predominantly fixed income securities consisting of investment-grade corporate bonds and various types of mortgage instruments. Management regularly reviews its BOLI investment performance, including concentrations among insurance providers.
Private Equity Investments
Private equity investments are measured under Level 3. The Equity Investments Committee, consisting of executives familiar with the investments, reviews periodic financial information, including audited financial statements when available. Certain analytics may be employed that include current and projected financial performance, recent financing activities, economic and market conditions, market comparables, market liquidity, sales restrictions, and other factors. The amount of unfunded commitments to invest is disclosed in Note 17. Certain restrictions apply for the redemption of these investments and certain investments are prohibited by the VR. See discussions in Notes 5 and 17.
Agriculture Loan Servicing
This asset results from our servicing of agriculture loans approved and funded by FAMC. We provide this servicing under an agreement with FAMC for loans they own. The asset’s fair value represents our projection of the present value of future cash flows measured under Level 3 using discounted cash flow methodologies.
Interest-Only Strips
Interest-only strips are created as a by-product of the securitization process. When the guaranteed portions of SBA 7(a) loans are pooled, interest-only strips may be created in the pooling process. The asset’s fair value represents our projection of the present value of future cash flows measured under Level 3 using discounted cash flow methodologies.
Deferred Compensation Plan Assets and Obligations
Invested assets in the deferred compensation plan consist of shares of registered investment companies. These mutual funds are valued under Level 1 at quoted market prices, which represents the NAV of shares held by the plan at the end of the period.
Derivatives
Derivatives are measured according to their classification as either exchange-traded or over-the-counter (“OTC”). Exchange-traded derivatives consist of foreign currency exchange contracts measured under Level 1 because they are traded in active markets. OTC derivatives, including those for customers, consist of interest rate swaps and options. These derivatives are measured under Level 2 using third party services. Observable market inputs include yield curves (the LIBOR swap curve and relevant overnight index swap curves), foreign exchange rates, commodity

150


Table of Contents

prices, option volatilities, counterparty credit risk, and other related data. Credit valuation adjustments are required to reflect nonperformance risk for both the Company and the respective counterparty. These adjustments are determined generally by applying a credit spread to the total expected exposure of the derivative.
Securities Sold, Not Yet Purchased
Securities sold, not yet purchased, included in “Federal funds and other short-term borrowings” on the balance sheet, are measured under Level 1 using quoted market prices. If not available, quoted prices under Level 2 for similar securities are used.

The previous fair values may not be current as of the dates indicated, but rather as of the date the fair value change occurred, such as a charge for impairment. Accordingly, carrying values may not equal current fair value.

We recognized net gains of $4.0 million in 2015 and $8.8 million in 2014 from the sale of OREO properties that had a carrying value at the time of sale of approximately $19.2 million in 2015 and $41.4 million in 2014. Previous to their sale in these years, we recognized impairment on these properties of $0.6 million in 2015 and $0.7 million in 2014.

Private equity investments carried at cost were measured at fair value for impairment purposes according to the methodology previously discussed for these investments. Amounts of PEIs carried at cost were $25.3 million and $39.1 million at December 31, 2015 and 2014, respectively. Amounts of other noninterest-bearing investments carried at cost were $191.5 million and $224.4 million at December 31, 2015 and 2014, respectively, which were comprised of Federal Reserve and FHLB stock.

Table of Contents

Impaired (or nonperforming) loans that are collateral-dependent were measured at fair value based on the fair value of the collateral. OREO was measured initially at fair value based on property appraisals at the time of transfer and subsequently at the lower of cost or fair value.

Measurement of fair value for collateral-dependent loans and OREO was based on third party appraisals that utilize one or more valuation techniques (income, market and/or cost approaches). Any adjustments to calculated fair value were made based on recently completed and validated third party appraisals, third party appraisal services, automated valuation services, or our informed judgment. Evaluations were made to determine that the appraisal process met the relevant concepts and requirements of applicable accounting guidance.

Automated valuation services may be used primarily for residential properties when values from any of the previous methods were not available within 90 days of the balance sheet date. These services use models based on market, economic, and demographic values. The use of these models has only occurred in a very few instances and the related property valuations have not been significant to consider disclosure under Level 3 rather than Level 2.

Impaired loans that are not collateral-dependent were measured based on the present value of future cash flows discounted at the expected coupon rates over the lives of the loans. Because the loans were not discounted at market interest rates, the valuations do not represent fair value and have been excluded from the nonrecurring fair value balance in the preceding schedules.

This summary excludes financial assets and liabilities for which carrying value approximates fair value and financial instruments that are recorded at fair value on a recurring basis. Financial instruments for which carrying values approximate fair value include cash and due from banks, money market investments, demand, savings and money market deposits, and federal funds purchased and security repurchase agreements. The estimated fair value of demand, savings and money market deposits is the amount payable on demand at the reporting date. Carrying value is used because the accounts have no stated maturity and the customer has the ability to withdraw funds immediately.

HTM investment securities primarily consist of municipal securities. They were measured at fair value according to the methodology previously discussed.

Loans are measured at fair value according to their status as nonimpaired or impaired. For nonimpaired loans, fair value is estimated by discounting future cash flows using the LIBOR yield curve adjusted by a factor which reflects the credit and interest rate risk inherent in the loan. These future cash flows are then reduced by the estimated “life-of-the-loan” aggregate credit losses in the loan portfolio. These adjustments for lifetime future credit losses are derived from the methods used to estimate the ALLL for our loan portfolio and are adjusted quarterly as necessary

to reflect the most recent loss experience. Impaired loans that are collateral-dependent are already considered to be held at fair value. Impaired loans that are not collateral-dependent have future cash flows reduced by the estimated “life-of-the-loan” credit loss derived from methods used to estimate the ALLL for these loans. See Impaired Loans in Note 6 for details on the impairment measurement method for impaired loans. Loans, other than those held for sale, are not normally purchased and sold by the Company, and there are no active trading markets for most of this portfolio. At December 31, 2015, oil and gas-related loan fair value measurement incorporated an illiquidity risk premium in addition to credit and interest rate risk adjustments.

Time and foreign deposits, and any other short-term borrowings, are measured at fair value by discounting future cash flows using the LIBOR yield curve to the given maturity dates.

Long-term debt is measured at fair value based on actual market trades (i.e., an asset value) when available, or discounting cash flows to maturity using the LIBOR yield curve adjusted for credit spreads.

These fair value disclosures represent our best estimates based on relevant market information and information about the financial instruments. Fair value estimates are based on judgments regarding current economic conditions, future expected loss experience, risk characteristics of the various instruments, and other factors. These estimates are subjective in nature, involve uncertainties and matters of significant judgment, and cannot be determined with precision. Changes in these methodologies and assumptions could significantly affect the estimates.

OPERATING SEGMENT INFORMATION
We manage our operations and prepare management reports and other information with a primary focus on geographical area. As discussed in Note 1, following the close of business on December 31, 2015, the Company’s seven subsidiary banks and certain other subsidiaries were merged into a single entity, whose name was changed to ZB, N.A. Effective April 1, 2015, TCBO was merged into TCBW. These consolidations will affect the presentation of segment reporting, although certain geographical information will continue. Certain prior year amounts have been reclassified to conform with the current year presentation. These reclassifications did not affect net income.
As of December 31, 2015, our banking business is conducted through seven locally managed and branded segments in distinct geographical areas. Performance assessment and resource allocation are based upon this geographical structure. Zions Bank operates 99 branches in Utah, 24 branches in Idaho, and one branch in Wyoming. CB&T operates 94 branches in California. Amegy operates 77 branches in Texas. NBAZ operates 67 branches in Arizona. NSB operates 49 branches in Nevada. Vectra operates 36 branches in Colorado and one branch in New Mexico. TCBW operates one branch in the Washington and one branch in Oregon.

The operating segment identified as “Other” includes the Parent, Zions Management Services Company (“ZMSC”) (which was merged into Zions First National Bank on December 31,2015), certain nonbank financial service subsidiaries, and eliminations of transactions between segments. The Parent’s operations are significant to the Other segment. The Company’s net interest income is substantially affected by the Parent’s interest expense on long-term debt. The Parent’s financial statements in Note 23 provide more information about the Parent’s activities. The condensed statement of income identifies the components of income and expense which affect the operating amounts presented in the Other segment.

ZMSC provided internal technology and operational services to affiliated operating businesses of the Company. ZMSC charges most of its costs to the affiliates on an approximate break-even basis.

The accounting policies of the individual operating segments are the same as those of the Company. Transactions between operating segments are primarily conducted at fair value, resulting in profits that are eliminated for reporting consolidated results of operations. Operating segments pay for centrally provided services based upon estimated or actual usage of those services.
