• heightened regulatory and governmental oversight and scrutiny of the Company’s business practices, including dealings with retail customers;

• changes in the economy of and monetary policy in the People’s Republic of China;

• changes in income tax laws and regulations;

• changes in accounting standards as may be required by the Financial Accounting Standards Board (“FASB”) or other regulatory agencies and their impact on critical accounting policies and assumptions;

• changes in the equity and debt securities markets;

• future credit quality and performance, including the Company’s expectations regarding future credit losses and allowance levels;

• fluctuations of the Company’s stock price;

• fluctuations in foreign currency exchange rates;

• success and timing of the Company’s business strategies;

• ability of the Company to adopt and successfully integrate new technologies into its business in a strategic manner;

• impact of reputational risk from negative publicity, fines and penalties and other negative consequences from regulatory violations and legal actions;

• impact of potential federal tax increases and spending cuts;

• impact of adverse judgments or settlements in litigation;

• impact of regulatory enforcement actions;

• changes in the Company’s ability to receive dividends from its subsidiaries;

• impact of political developments, wars or other hostilities that may disrupt or increase volatility in securities or otherwise affect economic conditions;

• impact of natural or man-made disasters or calamities or conflicts;

• continuing consolidation in the financial services industry;

• the Company’s capital requirements and its ability to generate capital internally or raise capital on favorable terms;

3

• impact of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) on the Company’s business, business practices and cost of operations;

• impact of adverse changes to the Company’s credit ratings from the major credit rating agencies;

• impact of failure in, or breach of, the Company’s operational or security systems or infrastructure, or those of third parties with whom the Company does business, including as a result of cyber attacks; and other similar matters which could result in, among other things, confidential and/or proprietary information being disclosed or misused;

• adequacy of the Company’s risk management framework, disclosure controls and procedures and internal control over financial reporting;

• the effect of the current low interest rate environment or changes in interest rates on the Company’s net interest income and net interest margin;

• the effect of changes in the level of checking or saving account deposits on the Company’s funding costs and net interest margin; and

• a recurrence of significant turbulence or disruption in the capital or financial markets, which could result in, among other things, a reduction in the availability of funding or increased funding costs, reduced investor demand for mortgage loans and declines in asset values and/or recognition of other-than-temporary impairment on securities held in the Company’s available-for-sale investment securities portfolio.

For a more detailed discussion of some of the factors that might cause such differences, see Item 1A. Risk Factors presented elsewhere in this report. The Company does not undertake, and specifically disclaims any obligation to update any forward-looking statements to reflect the occurrence of events or circumstances after the date of such statements except as required by law.

ITEM 1.  BUSINESS

Organization

East West is a bank holding company incorporated in Delaware on August 26, 1998 and is registered under the Bank Holding Company Act of 1956, as amended (“BHCA”). The Company commenced business on December 30, 1998 when, pursuant to a reorganization, it acquired all of the voting stock of East West Bank (the “Bank”), which became its principal asset. In addition to the Bank, East West has seven other subsidiaries as of December 31, 2016. Six of these subsidiaries were established as statutory business trusts (the “Trusts”) for the purpose of issuing junior subordinated debt to third party investors. The remaining subsidiary, East West Insurance Services, Inc. (the “Agency”), provides business and consumer insurance services.

East West’s principal business is to serve as a holding company for the Bank and other banking or banking-related subsidiaries, which East West may establish or acquire. As a legal entity separate and distinct from its subsidiaries, East West’s principal source of funds is, and will continue to be, dividends that may be paid by its subsidiaries. East West’s other sources of funds include proceeds from the issuance of its common stock in connection with stock option and employee stock purchase plans. As of December 31, 2016, the Company had $34.79 billion in total assets, $25.27 billion in total loans (net of allowance), $29.89 billion in total deposits and $3.43 billion in stockholders’ equity.

As of December 31, 2016, the Bank has three wholly owned subsidiaries. The first subsidiary, E-W Services, Inc., is a California corporation organized by the Bank in 1977 to hold properties used by the Bank in its operations. The second subsidiary, East-West Investment, Inc., primarily acts as a trustee in connection with real estate secured loans. The remaining subsidiary is East West Bank (China) Limited.

On November 6, 2009, the Bank acquired United Commercial Bank (“UCB”), a California state-chartered bank headquartered in San Francisco, California. Under the terms of the UCB Purchase and Assumption Agreement, the Bank acquired certain assets of UCB with a fair value of approximately $9.86 billion and assumed liabilities with a fair value of approximately $9.57 billion. On June 11, 2010, the Bank acquired certain assets and assumed certain liabilities of Washington First International Bank (“WFIB”), a Washington state-chartered bank headquartered in Seattle, Washington. Under the terms of the WFIB Purchase and Assumption Agreement, the Bank acquired certain assets of WFIB with a fair value of approximately $492.6 million and assumed liabilities with a fair value of approximately $481.3 million. Both of these transactions were FDIC-assisted acquisitions. On January 17, 2014, the Bank completed the acquisition of MetroCorp Bancshares, Inc., (“MetroCorp”) parent of MetroBank, N.A. and Metro United Bank. MetroCorp, headquartered in Houston, Texas, operated 19 branch locations within Texas and California under its two banks. The Bank acquired MetroCorp to further expand its market presence, primarily in Houston and Dallas, Texas and San Diego, California. Approximately $1.70 billion of assets were acquired and $1.41 billion of liabilities were assumed.

The Bank continues to develop its international banking capabilities with its network of branches and representative offices. The Bank’s presence includes five full-service branches in Greater China, located in Hong Kong, Shanghai, Shantou and Shenzhen. Shanghai has two branches, including one in the Shanghai Pilot Free Trade Zone. The Bank also has five representative offices in Greater China located in Beijing, Chongqing, Guangzhou, Taipei and Xiamen. In addition to facilitating traditional letters of credit and trade finance to businesses, these representative offices allow the Bank to assist existing clients and develop new business relationships. Through these branches and offices, the Bank is focused on growing its cross-border client base between the U.S. and Greater China, helping U.S. based businesses expand in Greater China and China based middle market companies pursue business opportunities in the U.S. The assets, revenues and earnings attributable to activities in the foreign locations were not material as of December 31, 2016 and 2015 and for the years ended December 31, 2016, 2015 and 2014.

The Bank continues to explore opportunities to establish other foreign offices, subsidiaries, strategic investments and partnerships to expand its international banking capabilities and to capitalize on cross-border businesses between the U.S. and Greater China.

Banking Services

As of December 31, 2016, the Bank was the fourth largest independent commercial bank headquartered in California based on total assets. The Bank is the largest bank in the U.S. that focuses on the financial service needs of individuals and businesses,which operate both in the U.S. and Greater China and has a strong focus on the Chinese American community. Through its network of banking locations in the U.S. and Greater China, the Bank provides a wide range of personal and commercial banking services to businesses, business executives, professionals, and other individuals. The Bank provides multilingual services to its customers in English, Cantonese, Mandarin, Vietnamese, Tagalog, Taiwanese and Spanish. The Bank also offers a variety of deposit products which includes the traditional range of personal and business checking and saving accounts, time deposits and individual retirement accounts, travelers checks, safe deposit boxes, and MasterCard^® and Visa^® merchant deposit services. The Bank’s lending activities include commercial and residential real estate, construction, trade finance, and commercial business, including accounts receivable, Small Business Administration, inventory and working capital loans. In addition, the Bank is focused on providing financing to clients in need of a financial bridge to facilitate their business transactions between the U.S. and Greater China.

The Bank’s three operating segments: Retail Banking, Commercial Banking and Other are based on the Bank’s core strategy. The Retail Banking segment focuses primarily on retail operations through the Bank’s branch network. The Commercial Banking segment primarily generates commercial and industrial (“C&I”) loans and commercial real estate (“CRE”) loans through domestic commercial lending offices located in California, New York, Texas, Washington, Massachusetts, Nevada and Georgia, and through foreign commercial lending offices located in China and Hong Kong. Furthermore, the Commercial Banking segment also offers a wide variety of international finance and trade services and products. The remaining centralized functions, including the Company’s treasury operations and intersegment amount eliminations were aggregated and included in “Other.” For complete discussion and disclosure, see the information in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations(“MD&A”) —Operating Segment Results and Note 19— Business Segments to the Consolidated Financial Statements for additional information.

Market Area and Competition

The Bank operates in a highly competitive environment. The Company faces competition from domestic and foreign lending institutions and numerous other providers of financial services. Competition is based on a number of factors including, among others, customer service, quality and range of products and services offered, reputation, interest rates on loans and deposits, lending limits and customer convenience. Competition also varies based on the types of customers and locations served. The Company maintains a strong presence within select markets through providing cross-border expertise to customers across a number of industry specializations between the U.S and Greater China. While the Company believes it is well positioned within the highly competitive industry, the industry could become even more competitive as a result of legislative, regulatory, economic, and technological changes, as well as continued consolidation.

The Bank concentrates on marketing its services in the greater Los Angeles metropolitan area and the greater San Francisco Bay area as California continues to grow as a top trading partner with Greater China and other Pacific Rim countries.  This provides the Bank with an important competitive advantage to its customers participating in the Asia Pacific marketplace. The Bank believes that its customers benefit from the Bank’s understanding of the Asian markets through its physical presence in Greater China, the Bank’s corporate and organizational ties throughout Asia, as well as the Bank’s international banking products and services. The Bank believes that this approach, combined with the Bank’s management and Board of Directors’ (the “ Board”) extensive ties to growing Asian business opportunities and the Chinese-American communities, provide the Bank with a competitive advantage. The Bank also has its presence in Greater China to identify and build corporate relationships, which the Bank can do business in California and its other U.S. markets.

Supervision and Regulation

General

East West and the Bank are extensively regulated under both federal and state laws. Regulation and supervision by the federal and state banking agencies are intended primarily for the protection of depositors, the Deposit Insurance Fund (“DIF”) administered by the FDIC and the banking system as a whole, and not for the protection of our stockholders. As a bank holding company, East West is subject to primary inspection, supervision, regulation, and examination by the Board of Governors of the Federal Reserve under the BHCA. The Bank, as a California state-chartered bank and a member of the Federal Reserve System, is subject to primary supervision and examination by the Federal Reserve, as well as the DBO - Division of Financial Institutions. The Company is also subject to regulation by certain foreign regulatory agencies where we conduct business.

6

The Company is also subject to the disclosure and regulatory requirements of the Securities Act of 1933, as amended, and the Exchange Act as administered by the SEC. Our common stock is listed on the NASDAQ Global Select Market (“NASDAQ”) under the trading symbol “EWBC” and is subject to NASDAQ rules for listed companies. The Company is also subject to the accounting oversight and corporate governance of the Sarbanes-Oxley Act of 2002.

Described below are material elements of selected laws and regulations applicable to East West and the Bank. 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. A change in applicable statutes, regulations or regulatory policy may have a material effect on the Company’s business.

East West

East West is subject to regulation and examination by the Federal Reserve under the BHCA and its authority to, among other things:

• require periodic reports and such additional information as the Federal Reserve may require;

• require the Company to maintain certain levels of capital and, under the Dodd-Frank Act, limit the ability of bank holding companies to pay dividends or bonuses unless their capital levels exceed the capital conservation buffer (see Item 1. Business — Supervision and Regulation — Capital Requirements);

• require bank holding companies to serve as a source of financial and managerial strength to subsidiary banks and commit resources, as necessary, to support each subsidiary bank. A bank holding company’s failure to meet its obligations to serve as a source of strength to its subsidiary banks will generally be considered by the Federal Reserve to be an unsafe and unsound banking practice or a violation of Federal Reserve regulations or both;

• restrict the receipt and the payment of dividends;

• terminate an activity or terminate control of or liquidate or divest certain nonbank subsidiaries, affiliates or investments if the Federal Reserve believes that the activity or the control of the nonbank subsidiary or affiliate constitutes a significant risk to the financial safety, soundness or stability of the bank holding company;

• regulate provisions of certain bank holding company debt, including the authority to impose interest ceilings and reserve requirements on such debt and require prior approval to purchase or redeem the Company’s securities in certain situations;

• require the prior approval of senior executive officer or director changes and prohibit golden parachute payments, including change in control agreements, or new employment agreements with such payment terms, which are contingent upon termination, under certain circumstances;

• approve acquisitions and mergers with banks and consider certain competitive, management, financial and other factors in granting these approvals. DBO approvals may also be required for certain mergers and acquisitions.

As a bank holding company within the meaning of the California Financial Code, East West is subject to examination by, and may be required to file reports with, the DBO.

The Bank and its Subsidiaries

East West Bank is a California state-chartered bank, a member and stockholder of the Federal Reserve and a member of the FDIC. The Bank is subject to primary inspection, periodic examination, and supervision by the CFPB, DBO, and the Federal Reserve (the Bank’s primary federal regulator). The Federal Reserve and the DBO also regulate the Bank’s foreign operations. The Bank’s foreign operations are also subject to the supervisory authorities of the host countries in which the Bank’s overseas offices reside. Specific federal and state laws and regulations that are applicable to banks regulate, among other things, the scope of their business, their investments, their reserves against deposits, the timing of the availability of deposited funds, and the nature and amount of collateral for certain loans. The regulatory structure also gives the bank regulatory agencies extensive discretion in connection with their supervisory and enforcement activities and examination policies. California law permits state chartered commercial banks to engage in any activity permissible for national banks, unless such activity is expressly prohibited by state law. Therefore, the Bank may form subsidiaries to engage in the many so-called “closely related to banking” or “nonbanking” activities commonly conducted by national banks in operating subsidiaries, and further, pursuant to the Gramm Leach Bliley Act, the Bank may conduct certain “financial” activities in a subsidiary to the same extent permitted for a national bank, provided the Bank is and remains “well capitalized,” “well managed” and “in satisfactory” compliance with the Community Reinvestment Act (“CRA”).

7

Regulation of Subsidiaries/Branches

The Bank’s foreign-based subsidiary, East West Bank (China) Limited, is subject to applicable foreign laws and regulations, such as those implemented by the China Banking Regulatory Commission. Nonbank subsidiaries are subject to additional or separate regulation and supervision by other state, federal and self-regulatory bodies. The Agency is subject to the licensing and supervisory authority of the California Department of Insurance. The East West Bank Hong Kong branch is subject to applicable foreign laws and regulations, such as those implemented by the Hong Kong Monetary Authority.

Dodd-Frank Act

The Dodd-Frank Act, which was enacted in July 2010, comprehensively reformed the regulation of financial institutions and their products and services. The Dodd-Frank Act also significantly revised and expanded the rulemaking, supervisory and enforcement authority of the federal bank regulatory agencies. Among other things, the Dodd-Frank Act established the CFPB to be responsible for consumer protection in the financial services industry; provided for new capital standards that eliminate the treatment of trust preferred securities as Tier I regulatory capital; required that deposit insurance assessments be calculated based on an insured depository institution’s assets rather than its insured deposits; raised the minimum Designated Reserve Ratio to 1.35%; established a comprehensive regulatory regime for the derivatives activities of financial institutions; established new compensation restrictions and standards regarding the time, manner and form of compensation given to key executives and other personnel receiving incentive compensation; prohibited banking entities, after a transition period, from engaging in certain types of proprietary trading, as well as having investments in, sponsoring, and maintaining certain types of relationships with hedge funds and private equity funds (through provisions commonly referred to as the “Volcker Rule”); placed limitations on the interchange fees charged for debit card transactions; and established new minimum mortgage underwriting standards for residential mortgages.

The Dodd-Frank Act impacts many aspects of the financial industry and will impact larger and smaller financial institutions and community banks differently over time. Many of the key provisions of the Dodd-Frank Act affecting the financial industry are either in effect or are in the proposed rules or implementation stages. The Company will continue to assess our businesses and risk management and compliance practices to conform to developments in the regulatory environment.

CFPB Supervision

The Dodd-Frank Act centralized responsibility for consumer financial protection by creating a new agency, the CFPB, and giving it the authority for implementing, examining and enforcing compliance with federal consumer financial laws. Depository institutions with assets exceeding $10 billion (such as the Bank), their affiliates, and certain non-banks in the markets for consumer financial services (as determined by the CFPB) are subject to direct supervision by the CFPB, including any applicable examination, enforcement and reporting requirements the CFPB may establish. The CFPB is focused on:

• risks to consumers and compliance with federal consumer financial laws, when it evaluates the policies and practices of a financial institution;

• unfair, deceptive, or abusive practices, which the Dodd-Frank Act empowers CFPB to prevent through rulemaking, enforcement and examination;

• rulemaking to implement various federal consumer statutes such as the Home Mortgage Disclosure Act, Truth in Lending Act, Real Estate Settlement Procedures Act and Electronic Fund Transfer Act;

• the markets in which firms operate, and risks to consumers posed by activities in those markets; and

• holding lenders accountable for discriminatory dealer markups with respect to the indirect auto business.

The statutes and regulations that the CFPB enforces mandate certain disclosure and other requirements, and regulate the manner in which financial institutions must deal with customers when taking deposits, making loans, collecting loans, and providing other services.  In addition, the Department of Justice enforces the Servicemembers Civil Relief Act, which provides protection for military servicemembers and their families including a limitation on the ability to retake collateral in the event of default and a statutory interest rate cap for certain debts. Failure to comply with these laws can subject the Bank to various penalties, including, but not limited to, enforcement actions, injunctions, fines or criminal penalties, punitive damages or restitution to consumers, and the loss of certain contractual rights.  The Bank and the Company are also subject to federal and state laws prohibiting unfair or fraudulent business practices, untrue or misleading advertising and unfair competition.

8

Federal Home Loan Bank (“FHLB”) and Federal Reserve

The Bank is a member of the FHLB of San Francisco. As a FHLB member, the Bank is required to own a certain amount of capital stock in the FHLB. The Bank may also access the FHLB for both short-term and long-term secured borrowing sources. The Federal Reserve requires all depository institutions to maintain interest-earning reserves at specified levels against their transaction accounts. As of December 31, 2016, the Bank was in compliance with these requirements. The Bank is also a member bank of the Federal Reserve.

Dividends and Other Transfers of Funds

Dividends from the Bank constitute the principal source of income to East West. The Bank is subject to various statutory and regulatory restrictions on its ability to pay dividends. In addition, the banking agencies have the authority to prohibit or limit the Bank from paying dividends, depending upon the Bank’s financial condition, if such payment is deemed to constitute an unsafe or unsound practice. Furthermore, under the federal Prompt Corrective Action (“PCA”) regulations, the Federal Reserve or FDIC may prohibit a bank holding company from paying any dividends if the holding company’s bank subsidiary is classified as “undercapitalized.” For more information, see Capital Requirements below.

It is the Federal Reserve’s policy that bank holding companies should generally pay dividends on common stock only if the organization’s net income available to common stockholders over the past year has been sufficient to fully fund the dividends, and if the prospective rate of earnings retention appears consistent with the organization’s capital needs, asset quality and overall financial condition. It is also the Federal Reserve’s policy that bank holding companies should not maintain dividend levels that undermine the company’s ability to be a source of strength to its banking subsidiaries. The Federal Reserve requires bank holding companies to continuously review their dividend policy in light of their organizations’ financial condition and compliance with regulatory capital requirements, and has discouraged payment ratios that are at maximum allowable levels, unless both asset quality and capital are very strong.

Transactions with Affiliates

Federal laws strictly limit the ability of banks to engage in transactions with their affiliates, including their bank holding companies. Regulations promulgated by the Federal Reserve limit the types and amounts of these transactions that may take place and generally require those transactions to be on an arm's length basis. In general, these regulations require that “covered transactions” between a subsidiary bank and its parent company or the non-bank subsidiaries of the bank holding company are limited to 10% of the bank subsidiary's capital and surplus and, with respect to such parent company and all such non-bank subsidiaries, to an aggregate of 20% of the bank subsidiary's capital and surplus. Further, these restrictions, contained in the Federal Reserve’s Regulation W, prevent East West and other affiliates from borrowing from, or entering into other credit transactions with, the Bank or its operating subsidiaries, unless the loans or other credit transactions are secured by specified amounts of collateral. Federal law also limits a bank's authority to extend credit to its directors, executive officers and 10% shareholders, as well as to entities controlled by such persons. Among other things, extensions of credit to insiders are required to be made on terms that are substantially the same as, and follow credit underwriting procedures that are not less stringent than, those prevailing for comparable transactions with unaffiliated persons. The terms of such extensions of credit may not involve more than the normal risk of repayment or present other unfavorable features and may not exceed certain limitations on the amount of credit extended to such persons, individually and in the aggregate, which limits are based, in part, on the amount of the bank's capital. The Dodd-Frank Act treats derivative transactions resulting in credit exposure to an affiliate as covered transactions. It expands the transactions for which collateral is required to be maintained, and for all such transactions, it requires collateral to be maintained at all times. In addition, the Volcker Rule under the Dodd-Frank Act establishes certain prohibitions, restrictions and requirements (known as “Super 23A” and “Super 23B”) on transactions between a covered fund and a banking entity that serves as an investment manager, investment adviser, organizer and offeror, or sponsor with respect to that covered fund, regardless of whether the banking entity has an ownership interest in the fund.

9

Stress Testing for Banks with Assets of $10 Billion to $50 Billion

The Dodd-Frank Act requires stress testing of bank holding companies and banks that have more than $10 billion but less than $50 billion of total consolidated assets (“$10 - $50 billion companies”). Additional stress testing is required for banking organizations with total consolidated assets of $50 billion or more. $10 - $50 billion companies, including the Company and the Bank, are required to conduct annual company-run stress tests under rules issued by the federal bank regulatory agencies. Stress tests assess the potential impact of scenarios on the consolidated earnings, balance sheet and capital of a bank holding company or bank over a designated planning horizon of nine quarters, taking into account the organization’s current condition, risks, exposures, strategies, activities and such factors as the regulators may request of a specific organization. Each banking organization’s Board and senior management are required to review and approve the policies and procedures of their stress testing processes as frequently as economic conditions or the condition of the organization may warrant, and at least annually. They are also required to consider the results of the stress test in the normal course of business, including the banking organization’s capital planning (including dividends and share buybacks), assessment of capital adequacy and maintaining capital consistent with its risks, and risk management practices. The results of the stress tests are provided to the applicable federal banking agencies. The final rule requirement for public disclosure of a summary of the stress testing results for the $10 - $50 billion companies has been implemented starting with the 2014 stress test, with the disclosure requirements effective in June 2015. The Bank has developed a process to comply with the stress testing requirements, which process involves senior management and the Board. The Bank submits the results of the annual company-run stress tests to the Federal Reserve and makes summaries of the results of the company-run stress tests available to the public on its website.

CRA

Under the CRA as implemented by FDIC regulations, an institution has a continuing and affirmative obligation to help serve the credit needs of its communities, including the extension of credit to low- and moderate-income neighborhoods. The CRA requires public disclosure of the Bank’s CRA rating. Should the Bank fail to serve the community adequately, potential penalties may include regulatory denials of applications to expand branches, relocate, add subsidiaries and affiliates, expand into new financial activities, and merge with or purchase other financial institutions.

FDIC Deposit Insurance Assessments

The FDIC insures the Bank’s customer deposits through the DIF of the FDIC up to $250,000 for each depositor. The Bank is subject to deposit insurance assessments as determined by the FDIC. The Bank’s DIF assessment is calculated by multiplying its assessment rate by the assessment base, which is defined as the average consolidated total assets less the average tangible equity of the Bank. The initial base assessment rate is based on an institution’s capital level, and capital adequacy, asset quality, management, earnings, liquidity and sensitivity (“CAMELS”) ratings, certain financial measures to assess an institution’s ability to withstand asset related stress and funding related stress, and in some cases, additional discretionary adjustments by the FDIC to reflect additional risk factors. The FDIC’s DIF restoration plan is designed to ensure that the DIF reserve ratio reaches 1.35% by September 30, 2020. Insured institutions with assets of $10 billion or more, such as the Bank, are responsible for funding the increase. With the increase of the DIF reserve ratio to 1.17% on June 30, 2016, the range of initial assessment rates has declined for all banks from five to 35 basis points on an annualized basis to three to 30 basis points on an annualized basis. In order to reach a DIF reserve ratio of 1.35%, insured depository institutions with $10 billion or more in total assets, such as the Bank, are required to pay a quarterly surcharge equal to an annual rate of 4.5 basis points applied to the Bank’s assessment base (with certain adjustments), in addition to regular assessments. In the event that the reserve ratio does not reach 1.35% by December 31, 2018, the FDIC will impose a shortfall on large banks in the first quarter of 2019. For additional information regarding deposit insurance, see Item 1A. Risk Factors. The FDIC may terminate a depository institution’s deposit insurance upon a finding that the institution’s financial condition is unsafe or unsound or that the institution has engaged in unsafe or unsound practices that pose a risk to the DIF or that may prejudice the interest of the bank’s depositors. The termination of deposit insurance for the Bank would also result in the revocation of the Bank’s charter by the DBO.

Anti-Money Laundering (“AML”) and Office of Foreign Assets Control (“OFAC”) Regulation

A major focus of governmental policy on financial institutions in recent years has been aimed at combating money laundering and terrorist financing. The Bank Secrecy Act (“BSA”) and its implementing regulations and parallel requirements of the federal banking regulators require the Bank to maintain a risk-based AML program reasonably designed to prevent and detect money laundering and terrorist financing and to comply with the recordkeeping and reporting requirements of the BSA, including the requirement to report suspicious activities. There is an expectation by the Bank’s regulators that there will be an effective governance structure for the program which includes effective oversight by our Board and management. The program must include, at a minimum, a designated compliance officer, written policies, procedures and internal controls, training of appropriate personnel and independent testing of the program, and a customer identification program. The United States Department of Treasury’s Financial Crimes Enforcement Network (“FinCEN”) and the federal banking agencies continue to issue regulations and guidance with respect to the application and requirements of the BSA and their expectations for effective AML programs. Banking regulators also examine banks for compliance with regulations administered by the OFAC for economic sanctions against targeted foreign countries, nationals and others. Failure of a financial institution to maintain and implement adequate BSA/AML and OFAC programs, or to comply with all of the relevant laws or regulations, could have serious legal and reputational consequences for the institution.

Capital Requirements

The federal banking agencies have risk-based capital adequacy guidelines intended to provide a measure of capital adequacy that reflects the degree of risk associated with a banking organization’s operations, both for transactions reported on the balance sheet as assets and for transactions, such as letters of credit and recourse arrangements, that are recorded as off-balance sheet items. In 2013, the Federal Reserve, FDIC, and Office of the Comptroller of the Currency issued 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 implementing certain provisions of the Dodd-Frank Act.

The Basel III Capital Rules became effective for the Company and the Bank on January 1, 2015 (subject to phase-in periods for some of their components). The Basel III Capital Rules: (i) introduce a new capital measure called Common Equity Tier I (“CET1”) and a related regulatory capital ratio of CET1 to risk-weighted assets; (ii) specify that Tier I capital consists of CET1 and “Additional Tier I capital” instruments, which are instruments treated as Tier I instruments under the prior capital rules that meet certain revised requirements; (iii) mandate that most deductions or adjustments to regulatory capital measures be made to CET1 and not to the other components of capital; and (iv) expand the scope of the deductions from and adjustments to capital, as compared to existing regulations. Under the Basel III Capital Rules, for most banking organizations, the most common form of Additional Tier I capital is noncumulative perpetual preferred stock and the most common form of Tier II capital is subordinated notes and a portion of the allowance for loan and lease losses, in each case, subject to the Basel III Capital Rules’ specific requirements.

Under the Basel III Capital Rules, the following are the initial minimum capital ratios applicable to the Company and the Bank as of January 1, 2015:

• 4.5% CET1 to risk-weighted assets;

• 6.0% Tier I capital (that is, CET1 plus Additional Tier I capital) to risk-weighted assets;

• 8.0% total capital (that is, Tier I capital plus Tier II capital) to risk-weighted assets; and

• 4.0% Tier I leverage ratio.

11

The Basel III Capital Rules also introduced “capital conservation buffer,” composed entirely of CET1, on top of these minimum risk-weighted asset ratios. The capital conservation buffer is designed to absorb losses during periods of economic stress. 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 began on January 1, 2016 at 0.625% and will be phased in over a four-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). In 2016, banking organizations including the Company and the Bank were required to maintain a CET1 capital ratio of at least 5.125%, a Tier I capital ratio of at least 6.625%, and a total capital ratio of at least 8.625% to avoid limitations on capital distributions and certain discretionary incentive compensation payments. When fully phased-in on January 1, 2019, the Company and the Bank must maintain the following minimum capital ratios:

• 4.5% CET1 to risk-weighted assets, plus the capital conservation buffer, effectively resulting in a minimum ratio of CET1 to risk-weighted assets of at least 7%;

• 6.0% Tier I capital to risk-weighted assets, plus the capital conservation buffer, effectively resulting in a minimum Tier I capital ratio of at least 8.5%;

• 8.0% total capital to risk-weighted assets, plus the capital conservation buffer, effectively resulting in a minimum total capital ratio of at least 10.5%; and

• 4.0% Tier I leverage ratio.

The Basel III Capital Rules provide for a number of deductions from and adjustments to CET1. These include, for example, the requirement that (i) mortgage servicing rights, (ii) deferred tax assets arising from temporary differences that could not be realized through net operating loss carrybacks, and (iii) significant investments in non-consolidated financial entities be deducted from CET1 to the extent that any one such category exceeds 10% of CET1 or all such items, in the aggregate, exceed 15% of CET1. Implementation of the deductions and other adjustments to CET1 began on January 1, 2015 and would be phased-in over a four-year period (beginning at 40% on January 1, 2015 and an additional 20% per year thereafter). Under the Basel III Capital Rules, the effects of certain accumulated other comprehensive income or loss items are not excluded for the purposes of determining regulatory capital ratios; however, non-advanced approaches banking organizations (i.e., banking organizations with less than $250 billion in total consolidated assets or with less than $10 billion of on-balance sheet foreign exposures), including the Company and the Bank, may make a one-time permanent election to exclude these items. The Company and the Bank made this election in the first quarter of 2015’s call reports in order to avoid significant variations in the level of capital depending upon the impact of interest rate fluctuations on the fair value of its available-for-sale investment securities portfolio.

The Basel III Capital Rules prescribe a new standardized approach for risk weightings that expands the risk weighting categories from the previous four Basel I-derived categories (0%, 20%, 50% and 100%) to a larger and more risk-sensitive number of categories, generally ranging from 0% for U.S. Government and agency securities, to 600% for certain equity exposures, depending on the nature of the assets. The new capital rules generally result in higher risk weights for a variety of asset classes, including certain CRE mortgages. Additional aspects of the Basel III Capital Rules that are relevant to the Company and the Bank include:

• consistent with the Basel I risk-based capital rules, assigning exposures secured by single-family residential properties to either a 50% risk weight for first-lien mortgages that meet prudent underwriting standards or a 100% risk weight category for all other mortgages;

• providing for a 20% credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable (set at 0% under the Basel I risk-based capital rules);

• assigning a 150% risk weight to all exposures that are nonaccrual or 90 days or more past due (set at 100% under the Basel I risk-based capital rules), except for those secured by single-family residential properties, which will be assigned a 100% risk weight, consistent with the Basel I risk-based capital rules;

• applying a 150% risk weight instead of a 100% risk weight for certain high volatility CRE acquisition, development and construction loans; and

• applying a 250% risk weight to the portion of mortgage servicing rights and deferred tax assets arising from temporary differences that could not be realized through net operating loss carrybacks that are not deducted from CET1 capital (set at 100% under the Basel I risk-based capital rules).

12

As of December 31, 2016, the Company’s and the Bank’s capital ratios exceeded the minimum capital adequacy guideline percentage requirements of the federal banking agencies for “well capitalized” institutions under the Basel III capital rules on a fully phased-in basis. For complete discussion and disclosure see Item 7. MD&A — Regulatory Capital and Ratios and Note 18 — Regulatory Requirementsand Matters to the Consolidated Financial Statements for additional information.

With respect to the Bank, the Basel III Capital Rules also revise the PCA regulations pursuant to Section 38 of the Federal Deposit Insurance Act, as discussed below under “PCA.”

PCA

The Federal Deposit Insurance Act, as amended (“FDIA”), requires federal banking agencies to take PCA in respect of depository institutions that do not meet minimum capital requirements. The FDIA includes the following five capital tiers: “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized,” and “critically undercapitalized.” A depository institution’s capital tier will depend upon how its capital levels compare with various relevant capital measures and certain other factors, as established by regulation. The Basel III Capital Rules, revised the PCA requirements effective January 1, 2015. Under the revised PCA provisions of the FDIA, an insured depository institution generally will be classified in the following categories based on the capital measures indicated:

PCA Category	Total Risk-Based Capital Ratio	Tier I Risk-Based Capital Ratio	CET1 Risk-Based Ratio	Tier I Leverage Ratio
Well capitalized	10%	8%	6.5%	5%
Adequately capitalized	8%	6%	4.5%	4%
Undercapitalized	< 8%	< 6%	< 4.5%	< 4%
Significantly undercapitalized	< 6%	< 4%	< 3.0%	< 3%
Critically undercapitalized	Tangible Equity/Total Assets ≤ 2%

An institution may be downgraded to, or deemed to be in, a capital category that is lower than indicated by its capital ratios, if it is determined to be in an unsafe or unsound condition or if it receives an unsatisfactory examination rating with respect to certain matters. A bank’s capital category is determined solely for the purpose of applying PCA regulations and the capital category may not constitute an accurate representation of the bank’s overall financial condition or prospects for other purposes.

The FDIA generally prohibits a depository institution from making any capital distributions (including payment of a dividend) or paying any management fee to its parent holding company, if the depository institution would thereafter be “undercapitalized.” “Undercapitalized” institutions are subject to growth limitations and are required to submit capital restoration plans. If a depository institution fails to submit an acceptable plan, it is treated as if it is “significantly undercapitalized.” “Significantly undercapitalized” depository institutions may be subject to a number of requirements and restrictions, including orders to sell sufficient voting stock to become “adequately capitalized,” requirements to reduce total assets, and cessation of receipt of deposits from correspondent banks. “Critically undercapitalized” institutions are subject to the appointment of a receiver or conservator.

Future Legislation and Regulation

Legislators, presidential administration and regulators may enact rules, laws, and policies to regulate the financial services industry and public companies from time to time. Further legislative changes and additional regulations may change the Company’s operating environment in substantial and unpredictable ways. Such legislation and regulations could increase the cost of conducting business, impede the efficiency of the internal business processes, and restrict or expand the activities in which the Company may engage. The Company cannot predict whether future legislative proposals will be enacted and, if enacted, the effect they would have on the business strategy, results of operations or financial condition of the Company. The same uncertainty exists with respect to regulations authorized or required under the Dodd-Frank Act that have not yet been proposed or finalized. Members of the current U.S. federal government administration have indicated that the Dodd-Frank Act will be evaluated and that some of the provisions of the Dodd-Frank Act and rules promulgated thereunder, including those provisions establishing the CFPB and the rules and regulations proposed and enacted by the CFPB, may be revised, repealed, or amended. It is unclear if this evaluation of the rules and regulations will result in material changes to the current laws and rules, or those that are in process, applicable to financial institutions like us and financial services or products like ours. It also is not clear what the impact from any such changes, whether positive or negative, would be on our business or the markets and industries in which we compete and any such changes could have a material adverse impact on our business and our prospects. There can be no assurance that these or future reforms will not significantly impact our business, results of operations and financial condition.

Employees

As of December 31, 2016, the Company had 2,873 employees. None of the Company’s employees are subject to any collective bargaining agreements.

ITEM 1A.  RISK FACTORS

In the course of conducting the Company’s businesses, the Company is exposed to a variety of risks, some of which are inherent in the financial services industry and others of which are more specific to the Company’s businesses. The following discussion sets forth what management currently believes could be the most significant factors, of which we are currently aware, that could affect our businesses, results of operations and financial condition. Additional factors that could affect our businesses, results of operations and financial condition are discussed in the Forward-Looking Statements. Other factors not discussed below or elsewhere in this Annual Report on Form 10-K could also adversely affect the Company’s businesses, results of operations and financial condition. Therefore, the risk factors below should not be considered a complete discussion of all of the risks and uncertainties the Company may face.

Regulatory, Compliance and Legal Risks

Changes in law, regulation or oversight may adversely affect the Company’s operations. EWBC is subject to extensive regulation under federal and state laws, as well as supervision and examination by the DBO, FDIC, Federal Reserve, SEC, CFPB, U.S. and State Attorneys General, and other government bodies. Congress and federal agencies have significantly increased their focus on the regulation of the financial services industry. Among other things, the Dodd-Frank Act, enacted in July 2010, instituted major changes to the banking and financial institutions regulatory regimes, many parts of which are now in effect. The Federal Reserve has adopted regulations implementing the Basel III framework on bank capital adequacy, stress testing, and market liquidity risk in the U.S. These regulations affect our lending practices, capital structure, investment practices, dividend policy and growth, among other things. Moreover, regulation of the financial services industry continues to undergo major changes. Changes to statutes, regulations or regulatory policies, including changes in interpretation or implementation of statutes, regulations or policies could affect EWBC in substantial and unpredictable ways. In addition, such changes could also subject us to additional costs and limit the types of financial services and products we may offer. Failure to comply with laws, regulations or policies could result in civil or criminal sanctions by state and federal agencies, the loss of FDIC insurance, the revocation of our banking charter, civil or criminal monetary penalties and/or reputational damage, which could have a material adverse impact on the Company’s businesses, results of operations and financial condition. The effects of such legislation and regulatory actions on EWBC cannot be reliably determined at this time. See Item 1. Business — Supervision and Regulation for more information about the regulations to which we are subject.

Good standing with our regulators is of fundamental importance to the continuation and growth of our businesses given that banks operate in an extensively regulated environment under state and federal law. The Bank is subject to supervision and regulation by regulators, including theFederal Reserve Bank of San Francisco (the “FRB”) and the DBO. Federal and state regulators, in the performance of their supervisory and enforcement duties, have significant discretion and power to initiate enforcement actions for violations of laws and regulations, and unsafe and unsound practices. The enforcement powers available to federal banking regulators include, among others, the ability to assess civil monetary penalties, to issue cease and desist or removal orders, to require written agreements, and to initiate injunctive actions.

The CFPB is in the process of reshaping the consumer financial laws through rulemaking and enforcement of such laws against unfair, deceptive and abusive acts or practices. Compliance with any such change may impact the business operations of depository institutions offering consumer financial products or services, including the Bank. The CFPB has broad rulemaking authority to administer and carry out the provisions of the Dodd-Frank Act with respect to financial institutions that offer covered financial products and services to consumers. The CFPB has also been directed to write rules identifying practices or acts that are unfair, deceptive or abusive in connection with any transaction with a consumer for a consumer financial product or service, or the offering of a consumer financial product or service. What constitutes unfair, deceptive and abusive acts or practices is clarified each year by CFPB enforcement actions and opinions from courts and administrative proceedings. Moreover, the Bank will be examined by the CFPB for compliance with the CFPB’s rules and regulations. The CFPB issued a series of final rules, which went into effect in January 2014, to implement provisions in the Dodd-Frank Act related to mortgage origination and servicing . While it is difficult to quantify the increase in our regulatory compliance burden, we do believe that costs associated with regulatory compliance, including the need to hire additional compliance personnel, may continue to increase.

15

We face risk of noncompliance and enforcement actions under the BSA and other AML statutes and regulations. The BSA requires banks and other financial institutions to, among other things, develop and maintain an effective anti-money laundering program and file suspicious activity and currency transaction reports as appropriate. FinCEN has delegated examination authority for compliance by banks with the BSA to the federal banking regulators, including to the Board of Governors of the Federal Reserve (the “Board of Governors”) for state licensed member banks. Under parallel authority of the bank regulators, the federal bank regulators and certain state regulators have authority to bring enforcement actions related to BSA compliance which may include compliance undertakings, written agreements, cease and desist orders, and/or civil monetary penalties. FinCEN may also impose civil monetary penalties based on BSA violations that are deemed willful. In addition, willful violations of the BSA also could result in criminal fines, penalties or forfeitures. The banking regulators also examine compliance with the rules enforced by the OFAC. Banks are under enhanced scrutiny for both BSA and OFAC compliance. Consequently, if our policies, procedures and internal controls are deemed deficient, we could face monetary penalties as well as serious reputational consequences that could materially and adversely affect our businesses, results of operations and financial condition.

The Bank is subject to supervision pursuant to a written agreement with the FRB and a memorandum of understanding with the DBO regarding BSA and AML compliance, which could result in additional actions taken against the Bank, will increase the Bank’s operating costs and could adversely affect the Bank’s results of operations.

The Bank entered into a Written Agreement, dated November 9, 2015 with the FRB (the “Written Agreement”), and a related memorandum of understanding (“MOU”) with the DBO, relating to certain deficiencies identified in the Bank’s BSA/AML compliance program, as described in further detail in Item 7. MD&A — Regulatory Matters. If additional compliance issues are identified or if the regulators conclude that the Bank has not satisfactorily complied with the Written Agreement, the DBO or the FRB could take further action with respect to the Bank, and if any such further action were taken, such action could have a material adverse effect on our businesses, results of operations and financial condition. The operating and other conditions of the Written Agreement could lead to an increased risk of being subject to additional regulatory actions by the DBO and FRB or other government agencies, as well as additional actions resulting from future regular annual soundness and compliance examinations by federal and state regulators.

We anticipate that we will need to continue to dedicate significant resources to our efforts to comply with the Written Agreement and related MOU, which are expected to increase our operational costs and adversely affect the amount of time our management has to conduct our businesses. The additional operating costs to comply with, and the restrictions under, the Written Agreement and MOU will adversely affect the Bank’s businesses, results of operations and financial condition.

We are subject to financial and reputational risk arising from lawsuits and other legal proceedings. We face significant risk from litigation and claims brought by consumers, borrowers and counterparties. This includes claims for monetary damages, penalties and fines, as well as demands for injunctive relief. The results of these lawsuits and other legal proceedings could lead to significant financial obligations for the Company, as well as restrictions or changes to how we conduct our businesses. The costs of litigation and defense may adversely impact our businesses, results of operations and financial condition. In addition, we may suffer reputational harm as a result of lawsuits and claims. Moreover, it may be difficult to predict the outcome of a lawsuit or legal proceeding, which may present additional uncertainty to our business prospects.

Increased deposit insurance costs and changes in deposit regulation may adversely affect the Company’s results of operations. The FDIC insures deposit accounts at banks and financial institutions, including the Bank. The FDIC charges the insured financial institutions premiums to maintain the DIF at a certain level. During 2008 and 2009, there were higher levels of bank failures, which dramatically increased resolution costs of the FDIC and depleted the DIF. The FDIC collected a special assessment in 2009 to replenish the DIF and also required a prepayment of an estimated amount of future deposit insurance premiums. In accordance with the Dodd-Frank Act, the FDIC adopted new rules that redefined how deposit insurance assessments are calculated. The new rate schedule and other revisions to the assessment rules became effective April 1, 2011, and had the effect of reducing the assessment that we would otherwise pay. As the new assessment rules currently stand, we expect the rules will have a continued positive impact on our future FDIC deposit insurance assessment fees compared to the assessment rules in effect prior to the changes. However, the FDIC’s rules could be subject to future changes, especially if there are additional bank or financial institution failures or the government or FDIC develop new regulatory goals with respect to the banking sector. Increases in assessment fees or required prepayments of FDIC insurance premiums may have an adverse effect on our businesses, results of operations and financial condition.

16

The Company’s interest expense may increase following the repeal of the federal prohibition on payment of interest on demand deposits. The federal prohibition on the ability of financial institutions to pay interest on demand deposit accounts was repealed as part of the Dodd-Frank Act beginning on July 21, 2011. As a result, financial institutions could commence offering interest on demand deposits to compete for clients. We cannot predict what interest rates other banks may offer as market interest rates increase in the future. The Bank offers interest on certain demand deposits to attract additional customers or to maintain current customers. If market interest rates increase, the Company’s interest expense will increase and net interest margin will decrease which could have a material adverse effect on the Company’s businesses, results of operations and financial condition.

Changes in accounting standards or inaccurate estimates or assumptions in applying accounting policies could materially impact the Company’s financial statements. From time to time, the FASB or the SEC may change the financial accounting and reporting standards that govern the preparation of the Company’s financial statements. In addition, the FASB, SEC, banking regulators and the Company’s independent registered public accounting firm may also amend or even reverse their previous interpretations or positions on how various standards should be applied. These changes may be difficult to predict and could impact how we prepare and report the Company’s financial statements. In some cases, we could be required to apply a new or revised standard retroactively, resulting in the Company revising and republishing prior-period financial statements.

Capital and Liquidity Risks

As a regulated entity, we are subject to capital and liquidity requirements, and a failure to meet these standards could affect our financial condition. The Company and the Bank are subject to certain capital and liquidity guidelines, qualitative judgments by regulators about components, risk weightings and other factors. New regulatory capital and liquidity requirements may limit or otherwise restrict how we utilize our capital, including common stock dividends and stock repurchases, and may require us to increase our regulatory capital, or increase regulatory capital ratios or liquidity. Significant parts of the capital requirements applicable to the Company and the Bank under the Basel III Capital Rules adopted by the Federal Reserve are effective, although certain provisions of the rules are phased-in over a period of years, with the rules generally fully phased-in as of January 1, 2019. We are required to satisfy more stringent capital adequacy and liquidity standards than we have in the past. 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 the hypothetical future adverse economic scenarios. We expect to meet the requirements of the Basel III Capital Rules, including the capital conservation buffer fully phased-in as of January 1, 2019 by the Federal Reserve. Compliance with these capital requirements, including leverage ratios, may limit operations that require intensive use of capital. This could adversely affect our ability to expand or maintain present business levels, which may adversely affect our businesses, results of operations and financial condition. Additional information on the regulatory capital requirements applicable to the Company and the Bank is set forth in Item 1. Business — Supervision and Regulation — Capital Requirements.

The Company’s ability to pay dividends.  East West is dependent on the Bank for dividends, distributions and other payments. Our principal source of cash flow, including cash flow to pay dividends to our stockholders and principal and interest on our outstanding debt, is dividend income from the Bank. The ability of the Bank to pay dividends to East West is limited by federal and California law. Subject to the Bank meeting or exceeding regulatory capital requirements, regulatory approval is required if the total of all dividends declared by the Bank in any calendar year would exceed the sum of the Bank’s net profits for that year and its retained net profits for the preceding two years. Federal law also prohibits the Bank from paying dividends that would be greater than its undivided profits. In addition, Federal Reserve guidance sets forth the supervisory expectation that bank holding companies will inform and consult with the Federal Reserve in advance of issuing a dividend that exceeds earnings for the quarter and should not pay dividends in a rolling four quarter period in an amount that exceeds net income for the period.

The Company is subject to liquidity risk, which could negatively affect the Company’s funding levels. Market conditions or other events could negatively affect the level of or cost of funding, which in turn could affect the Company’s ongoing ability to accommodate liability maturities and deposit withdrawals, meet contractual obligations, or fund asset growth and new business initiatives at a reasonable cost, in a timely manner and without adverse consequences. Although the Company has implemented strategies to maintain sufficient and diverse sources of funding to accommodate planned, as well as unanticipated changes in assets, liabilities, and off-balance sheet commitments under various economic conditions, a substantial, unexpected or prolonged change in the level or cost of liquidity could have a material adverse effect on the Company’s businesses, results of operations and financial condition. If the cost effectiveness or the availability of supply in the credit markets is reduced for a prolonged period of time, the Company’s funding needs may require the Company to access funding and manage liquidity by other means. These alternatives may include generating client deposits, securitizing or selling loans, and further managing loan growth and investment opportunities. These alternative means of funding may not be available under stressed conditions.

17

Market Risks

General economic, political or industry conditions may be less favorable than expected. Our businesses and results of operations are affected by the financial markets and general economic conditions in the U.S. and China, including factors such as the level and volatility of short-term and long-term interest rates, inflation, home prices, unemployment and under-employment levels, bankruptcies, household income, consumer spending, fluctuations in both debt and equity capital markets and currencies, liquidity of the global financial markets, the availability and cost of capital and credit, investor sentiment and confidence in the financial markets, and the sustainability of economic growth in the U.S. and China. The deterioration of any of these conditions could adversely affect our consumer and commercial businesses, our securities and derivatives portfolios, our level of charge-offs and provision for credit losses, the carrying value of our deferred tax assets, our capital levels and liquidity, and our results of operations. Because the Company’s operations and the collateral securing its loan portfolio are concentrated primarily in Northern and Southern California, the Company may be particularly susceptible to the adverse economic conditions in the state of California.

Despite improving labor markets and declines in energy costs, an elevated level of underemployment and household debt and prolonged low interest rates pose challenges for the domestic economic performance and the financial services industry. Home sales continue to show signs of improvement but the improvement in the housing market remains modest in certain areas. Mortgage delinquency and foreclosure rates continue to decline. Any unfavorable changes in the economic and market conditions would lead to the following risks:

• The process the Company uses to estimate losses inherent in the Company’s credit exposure requires difficult, subjective and complex judgments, including forecasts of economic conditions and how these economic conditions might impair the ability of the borrowers to repay their loans. The level of uncertainty concerning economic conditions may adversely affect the accuracy of the Company’s estimates which may, in turn, impact the reliability of the process.

• The Company’s commercial and residential borrowers may not be able to make timely repayments of their loans, or the decrease in value of real estate collateral securing the payment of such loans could result in credit losses, delinquencies, foreclosures and customer bankruptcies, any of which could have a material adverse effect on the Company’s operating results.

• A decrease in the demand for loans and other products and services offered by us.

• A decrease in deposit balances due to overall reductions in customers’ accounts.

• The value of the available-for-sale investment securities portfolio that the Company holds may be adversely affected by defaults by debtors.

• Future disruptions in the capital markets or other events, including actions by rating agencies and deteriorating investor expectations, may result in an inability to borrow on favorable terms or at all from other financial institutions.

A portion of the Company’s loan portfolio is secured by real estate and thus the Company has a higher degree of risk from a downturn in real estate markets.  As discussed in the “General economic, political or industry conditions may be less favorable than expected” section above, a decline in real estate markets could hurt the Company’s businesses because many of the Company’s loans are secured by real estate. Real estate values and real estate markets are generally affected by changes in national, regional or local economic conditions, fluctuations in interest rates and the availability of loans to potential purchasers, changes in tax laws and other governmental statutes, regulations and policies, and acts of nature and national disasters, such as earthquakes which are particular to California. A significant portion of the Company’s real estate collateral is located in California. If real estate values decline, the value of real estate collateral securing the Company’s loans could be significantly reduced. The Company’s ability to recover on defaulted loans by foreclosing and selling the real estate collateral would then be diminished and the Company would be more likely to suffer losses on defaulted loans. Furthermore, CRE and multifamily loans typically involve large balances to single borrowers or groups of related borrowers. Since payments on these loans are often dependent on the successful operation or management of the properties, as well as the business and financial condition of the borrower, repayment of such loans may be subject to adverse conditions in the real estate market, adverse economic conditions, or changes in applicable government regulations. Borrowers’ inability to repay such loans may have an adverse effect on the Company’s businesses, results of operations and financial condition.

18

The Company’s businesses are subject to interest rate risk and variations in interest rates may negatively affect the Company’s financial performance. Our financial results depend substantially on net interest income, which is the difference between the interest income we earn on interest-earning assets and the interest expense we pay on interest-bearing liabilities. Interest-earning assets primarily include loans extended, securities held in our investment portfolio and excess cash held to manage short-term liquidity. We fund our assets using deposits and borrowings. While we offer interest-bearing deposit products, a portion of our deposit balances are from noninterest-bearing products. Overall, the interest rates we receive on our interest-earning assets and pay on our interest-bearing liabilities could be affected by a variety of factors, including market interest rate changes, competition, regulatory requirements and a change in the product mix. Changes in key variable market interest rates such as the Federal Funds, National Prime, the London Interbank Offered Rate (“LIBOR”) or Treasury rates generally impact our interest rate spread. In addition, changes in interest rates could also affect the average life of our loans and mortgage related securities where decreases in interest rates resulting from actions taken by the Federal Reserve has caused an increase in prepayments of loans and mortgage related securities, as borrowers refinance to reduce borrowing costs. In addition, because of the differences in the maturities and repricing characteristics of the Company’s interest-earning assets and interest-bearing liabilities, changes in interest rates do not produce equivalent changes in interest income earned on interest-earning assets and interest paid on interest-bearing liabilities. Overall, interest rates have been at historically low levels for an unprecedented long period of time. Continued low interest rates, possibly compounded by a flat yield curve, may challenge the bank’s interest margin.

The fiscal and monetary policies of the federal government and its agencies could have a material adverse effect on our earnings. The Federal Reserve Board regulates the supply of money and credit in the U.S. Its policies determine in large part the cost of funds for lending and investing and the return earned on those loans and investments, both of which affect our net interest margin. They can also materially decrease the value of financial assets we hold. Federal Reserve policies may also adversely affect borrowers, potentially increasing the risk that they may fail to repay their loans, or could adversely create asset bubbles which result from prolonged periods of accommodative policy. This, in turn, may result in volatile markets and rapidly declining collateral values. Changes in Federal Reserve policies are beyond our control and difficult to predict; consequently, the impact of these changes on our activities and results of operations is difficult to predict. Also, potential new taxes on corporations generally, or on financial institutions specifically, would adversely affect our net income.

There may be substantial changes to fiscal and tax policies that may adversely affect our business. The U.S. government may make substantial changes to a variety of federal policies and regulations, including fiscal and tax policies that may affect our business. This may result in a significant reform of the Internal Revenue Code, including significant changes to taxation of business entities. There is a substantial lack of clarity around the likelihood, timing and details of any possible tax reforms or other policy changes and we cannot predict the impact, if any, of these changes on our business. However, it is possible that these reforms and changes could adversely affect our business.

We face risks associated with international operations.  A substantial number of our customers have economic and cultural ties to Asia and China. The Bank’s presence includes five full-service branches in Greater China, located in Hong Kong, Shanghai, Shantou and Shenzhen. Shanghai has two branches, including one in the Shanghai Pilot Free Trade Zone. The Bank also has five representative offices in Greater China located in Beijing, Chongqing, Guangzhou, Taipei and Xiamen. Our efforts to expand our businesses in Asia and China carry certain risks, including risks arising from the uncertainty regarding our ability to generate revenues from foreign operations, risks associated with leveraging and conducting business on an international basis, including among others, legal, regulatory and tax requirements and restrictions, uncertainties regarding liability, trade barriers, difficulties in staffing and managing foreign operations, political and economic risks, financial risks including currency and payment risks. Further, volatility in the Shanghai and Hong Kong stock exchanges and/or a potential dramatic fall in real estate prices in China, among other things, may negatively impact asset values and the profitability and liquidity of the Company’s customers who operate in this region. These risks could adversely affect the success of our international operations and could have a material adverse effect on our overall businesses, results of operations and financial condition. In addition, we face risks that our employees and affiliates may fail to comply with applicable laws and regulations governing our international operations, including the U.S. Foreign Corrupt Practices Act, anti-corruption laws, and other foreign laws and regulations. Failure to comply with such laws and regulations could, among other things, result in enforcement actions and fines against us, as well as limitations on our conduct, any of which could have a material adverse effect on our businesses, results of operations and financial condition.

The Company is subject to fluctuations in foreign currency exchange rates. The Company’s foreign translation exposure relates primarily to its China subsidiary that has its functional currency denominated in Chinese Renminbi (“RMB”). In addition, as the Company continues to expand its businesses in China and Hong Kong, certain transactions are conducted in currencies other than the U.S. Dollar (“USD”). Although the Company has entered into derivative instruments to offset the impact of the foreign exchange fluctuations, given the volatility of exchange rates, there is no assurance that the Company will be able to effectively manage foreign currency translation risk. Fluctuations in foreign currency exchange rates could have a material adverse effect on the Company’s businesses, results of operations and financial condition.

Credit Risks

The Company’s allowance for credit losses level may not be adequate to cover actual losses.  In accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”), we maintain an allowance for loan losses to provide for loan defaults and non-performance, and an allowance for unfunded credit reserves which, when combined, are referred to as the allowance for credit losses. Our allowance for loan losses is based on our evaluation of risks associated with our loans held-for-investment portfolio, including historical loss experience, expected loss calculations, delinquencies, performing status, the size and composition of the loan portfolio, economic conditions, and concentrations within the portfolio. The allowance estimation process requires subjective and complex judgments, including analysis of economic conditions and how these economic conditions might impair the ability of our borrowers to repay their loans. Current economic conditions in the U.S. and in the international markets could deteriorate, which could result in, among other things, greater than expected deterioration in credit quality of our loan portfolio or in the value of collateral securing these loans. Our allowance for loan losses may not be adequate to cover probable loan losses, and future provisions for loan losses could materially and adversely affect our results of operations and financial condition. Additionally, in order to maximize the collection of loan balances, we sometimes modify loan terms when there is a reasonable chance that an appropriate modification would allow the borrower to continue servicing the debt. If such modifications ultimately are less effective at mitigating loan losses than we expect, we may incur losses in excess of the specific amount of allowance for loan losses associated with a modified loan, and this would result in additional provision for loan losses. In addition, we establish a reserve for losses associated with our unfunded credit reserves. The level of the allowance for unfunded credit reserves is determined by following a methodology similar to that used to establish our allowance for loan losses in our loans held-for-investment portfolio. There can be no assurance that our allowance for unfunded credit reserves will be adequate to provide for the actual losses associated with our unfunded credit commitments. An increase in the allowance for unfunded credit reserves in any period may result in a charge to earnings.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. Under U.S. GAAP's current standards, credit losses are not reflected in the financial statements until it is probable that the credit loss has been incurred. Under ASU 2016-01, an entity would reflect in its financial statements its current estimate of credit losses on financial assets over the expected life of each financial asset. ASU 2016-01 may have a negative impact on our reported earnings, capital, regulatory capital ratios, as well as on regulatory limits which are based on capital, since it would accelerate the recognition of estimated credit losses.

We may be subject to increased credit risk and higher credit losses to the extent that our loans are concentrated by loan type, industry segment, borrower type, or location of the borrower or collateral. Our credit risk and credit losses can increase if our loans are concentrated in borrowers engaged in the same or similar economic conditions in those markets or elsewhere, which could result in materially higher credit losses. Deterioration in economic conditions, housing conditions, or real estate values in the markets in which we operate could result in materially higher credit losses. The Bank has a concentration of real estate loans in California. Potential deterioration in the real estate market could result in additional loan charge-offs and provision for loan losses, which could have a material adverse effect on the Company’s businesses, results of operations and financial condition.

Operational Risks

A failure in or breach of our operational or security systems or infrastructure, or those of third parties, could disrupt our businesses, and adversely impact our results of operations, cash flows, liquidity and financial condition, as well as cause reputational harm. The potential for operational risk exposure exists throughout our organization and from our interactions with third parties. Our operational and security systems, infrastructure, including our computer systems, network infrastructure, data management and internal processes, as well as those of third parties, are integral to our performance. In addition, we rely on our employees and third parties in our ongoing operations, who may, as a result of human error or malfeasance or failure or breach of third-party systems or infrastructure, expose us to risk. We have taken measures to implement backup systems and safeguards to support our operations, but our ability to conduct business may be adversely affected by any significant disruptions to us or to the third parties with whom we interact. In addition, our ability to implement backup systems and other safeguards with respect to third-party systems is more limited than with respect to our own systems. Our financial, accounting, data processing, backup or other operating or security systems and infrastructure may fail to operate properly or may become disabled or damaged as a result of a number of factors including events that are wholly or partially beyond our control which could adversely affect our ability to process these transactions or provide certain services. There could be electrical, telecommunications or other major physical infrastructure outages, natural disasters such as earthquakes, tornadoes, hurricanes and floods, disease pandemics, and events arising from local or larger scale political or social matters, including terrorist acts. We continuously update these systems to support our operations and growth, and this entails significant costs and creates risks associated with implementing new systems and integrating them with existing ones. Operational risk exposures could adversely impact our results of operations, cash flows, liquidity and financial condition, and may result in loss of confidence, significant litigation exposure and harm to our reputation.

20

A cyber attack, information or security breach, or a technology failure of ours or of a third party could adversely affect our ability to conduct our businesses, manage our exposure to risk or expand our businesses, result in the disclosure or misuse of confidential or proprietary information, increase our costs to maintain and update our operational and security systems and infrastructure, and adversely impact our results of operations, cash flows, liquidity and financial condition, as well as cause reputational harm. The Company offers various internet-based services to its clients, including online banking services. The secure transmission of confidential information over the internet is essential to maintain our clients’ confidence in the Company’s online services. In addition, our businesses are highly dependent on the security and efficacy of our infrastructure, computer and data management systems, as well as those of third parties with whom we interact. Cyber security risks for financial institutions have significantly increased in recent years in part because of the proliferation of new technologies, the use of the Internet and telecommunications technologies to conduct financial transactions, and the increased sophistication and activities of organized crime, hackers, terrorists and other external parties. Our businesses rely on the secure processing, transmission, storage and retrieval of confidential, proprietary and other information in our computer and data management systems and networks, and in the computer and data management systems and networks of third parties. We rely on digital technologies, computer, database and email systems, software and networks. Although the Company has developed systems and processes that are designed to prevent security breaches and periodically test the Company’s security, failure to mitigate breaches of security could adversely affect the Company’s ability to offer and grow the online services, result in violations of applicable privacy and other laws, costly litigation and loss of customer relationships and could have an adverse effect on the Company’s businesses, results of operations and financial condition.

Failure to keep pace with technological change could adversely affect the Company’s businesses. The Company may face risks associated with the ability to utilize information technology systems to support our operations effectively. The financial services industry is continually undergoing rapid technological change with frequent introductions of new technology-driven products and services. The effective use of technology increases efficiency and enables financial institutions to better serve customers and to reduce costs. The Company’s future success depends, in part, upon its ability to address the needs of its customers by using technology to provide products and services that will satisfy customer demands, as well as to create additional efficiencies in the Company’s operations. Many of the Company’s competitors have substantially greater resources to invest in technological improvements. The Company may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to its customers. Failure to successfully keep pace with technological change affecting the financial services industry could have a material adverse impact on the Company’s businesses and, in turn, the Company’s results of operations and financial condition. In addition, if we do not implement systems effectively or if our outsourcing business partners do not perform their functions properly, there could be an adverse effect on us. There can be no assurance that we will be able to effectively maintain or improve our systems and processes, or utilize outsourced talent, to meet our business needs efficiently. Any such failure could adversely affect our businesses, results of operations, financial condition, and reputation.

Natural disasters and geopolitical events beyond the Company’s control could adversely affect the Company.  Natural disasters such as earthquakes, wildfires, extreme weather conditions, hurricanes, floods, and other acts of nature and geopolitical events involving terrorism or military conflict could adversely affect the Company’s business operations and those of the Company’s customers and cause substantial damage and loss to real and personal property. These natural disasters and geopolitical events could impair the borrowers’ ability to service their loans, decrease the level and duration of deposits by customers, erode the value of loan collateral, and result in an increase in the amount of nonperforming assets, net charge-offs, and provision for loan losses, which could adversely affect the Company’s businesses, results of operations and financial condition.

The actions and soundness of other financial institutions could affect the Company.  Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships. The Company executes transactions with various counterparties in the financial industry, including brokers and dealers, commercial banks and investment banks. Defaults by financial services institutions and uncertainty in the financial services industry in general could lead to market wide liquidity problems and may expose the Company to credit risk in the event of default of its counterparty or client. Further, the Company’s credit risk may increase when the underlying collateral held cannot be realized or is liquidated at prices not sufficient to recover the full amount of the loan or derivative exposure due to the Company. Any such losses could materially and adversely affect the Company’s businesses, results of operations and financial condition.

The Company’s controls and procedures could fail or be circumvented. Management regularly reviews and updates the Company’s internal controls, disclosure controls and procedures, and corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, but not absolute, assurances of the effectiveness of these systems and controls, and that the objectives of these controls have been met. Any failure or circumvention of the Company’s controls and procedures, and any failure to comply with regulations related to controls and procedures could adversely affect the Company’s businesses, results of operations and financial condition.

21

The Company is dependent on key personnel and the loss of one or more of those key personnel may materially and adversely affect the Company’s prospects.  Competition for qualified employees and personnel in the banking industry is intense and there is a limited number of qualified persons with knowledge of, and experience in, the regional banking industry, especially in the West Coast market. The process of recruiting personnel with the combination of skills and attributes required to carry out the Company’s strategies is often lengthy. The Company’s success depends, to a significant degree, upon its ability to attract and retain qualified management, loan origination, finance, administrative, marketing and technical personnel, as well as upon the continued contributions of its management and personnel. In particular, the Company’s success has been and continues to be highly dependent upon the abilities of certain key executives.

We face strong competition in the financial services industry and we could lose business or suffer margin declines as a result. The Company’s financial performance and profitability also depend on the Company’s ability to compete with financial services companies and other companies that offer banking services. The Company conducts the majority of its operations in California. The banking and financial services businesses in California are highly competitive, and increased competition in the Company’s primary market area may adversely impact the level of loans and deposits. Ultimately, the Company may not be able to compete successfully against current and future competitors. These competitors include national banks, regional banks and other community banks. The Company also faces competition from many other types of financial institutions, including savings and loan associations, finance companies, brokerage firms, insurance companies, credit unions, mortgage banks and other financial intermediaries. In particular, the Company’s competitors include major financial companies whose greater resources may afford them a marketplace advantage by enabling them to maintain numerous locations and mount extensive promotional and advertising campaigns. Areas of competition include interest rates for loans and deposits, efforts to obtain loan and deposit customers and a range in quality of products and services provided, including new technology-driven products and services. If the Company is unable to attract and retain banking customers, the Company may be unable to continue its loan growth and level of deposits.

The Company has engaged in and may continue to engage in further expansion through acquisitions, which could negatively affect the Company’s businesses and earnings. There are risks associated with expansion through acquisitions. These risks include, among others, incorrectly assessing the asset quality of a bank acquired in a particular transaction, encountering greater than anticipated costs in integrating acquired businesses, facing resistance from customers or employees, and being unable to profitably deploy assets acquired in the transaction. Additional country- and region-specific risks are associated with transactions outside the U.S., including in China. To the extent the Company issues capital stock in connection with additional transactions, these transactions and related stock issuances may have a dilutive effect on earnings per share and share ownership.

Other Risks

Anti-takeover provisions could negatively impact the Company’s stockholders.  Provisions of Delaware law and of the Company’s certificate of incorporation, as amended, and bylaws could make it more difficult for a third party to acquire control of the Company or could have the effect of discouraging a third party from attempting to acquire control of the Company, even if an acquisition might be in the best interest of the stockholders. For example, the Company’s certificate of incorporation requires the approval of the holders of at least two-thirds of the outstanding shares of voting stock to approve certain business combinations. The Company is also subject to Section 203 of the Delaware General Corporation Law, which would make it more difficult for another party to acquire the Company without the approval of the Board. Additionally, the Company’s certificate of incorporation, as amended, authorizes the Board to issue preferred stock and preferred stock could be issued as a defensive measure in response to a takeover proposal. These and other provisions could make it more difficult for a third party to acquire the Company, even if an acquisition might be in the best interest of the stockholders.

Managing reputational risk is important to attracting and maintaining customers, investors and employees.  Threats to the Company’s reputation can come from many sources, including unethical practices, employee misconduct, failure to deliver minimum standards of service or quality, compliance deficiencies, and questionable or fraudulent activities of the Company’s customers. The Company has policies and procedures in place to protect its reputation and promote ethical conduct, but these policies and procedures may not be fully effective. Negative publicity regarding the Company’s businesses, employees or customers, with or without merit, may result in the loss of customers, investors and employees, costly litigation, a decline in revenues, and increased governmental regulation.

22

The price of the Company’s common stock may be volatile or may decline.  The trading price of the Company’s common stock may fluctuate as a result of a number of factors, many of which are outside the Company’s control. In addition, the stock market is subject to fluctuations in the share prices and trading volumes that affect the market prices of the shares of many companies. These broad market fluctuations could adversely affect the market price of the Company’s common stock. Among the factors that could affect the Company’s stock price are: 

• actual or anticipated quarterly fluctuations in the Company’s operating results and financial condition;

• changes in revenue or earnings estimates or publication of research reports and recommendations by financial analysts;

• failure to meet analysts’ revenue or earnings estimates;

• speculation in the press or investment community;

• strategic actions by the Company or its competitors, such as acquisitions or restructurings;

• actions by institutional stockholders;

• fluctuations in the stock price and operating results of the Company’s competitors;

• general market conditions and, in particular, developments related to market conditions for the financial services industry;

• proposed or adopted regulatory changes or developments;

• anticipated or pending investigations, proceedings or litigation that involve or affect the Company; and

• domestic and international economic factors unrelated to the Company’s performance.

 The stock market and, in particular, the market for financial institution stocks, has experienced significant volatility in the previous years. As a result, the market price of the Company’s common stock may be volatile. In addition, the trading volume in the Company’s common stock may fluctuate more than usual and cause significant price variations to occur. The trading price of the shares of the Company’s common stock and the value of other securities will depend on many factors, which may change from time to time, including, without limitation, the financial condition, performance, creditworthiness and prospects, and future sales of the equity or equity-related securities. In some cases, the markets have produced downward pressure on stock prices and credit availability for certain issuers without regard to those issuers’ underlying financial strength. A significant decline in the Company’s stock price could result in substantial losses for individual stockholders and could lead to costly and disruptive securities litigation.

If the Company’s goodwill were determined to be impaired, it would result in a charge against earnings and thus a reduction in stockholders’ equity. The Company tests goodwill for impairment on an annual basis, or more frequently, if necessary. Quoted market prices in active markets are the best evidence of fair value and are to be used as the basis for measuring impairment, when available. Other acceptable valuation methods include present-value measurements based on multiples of earnings or revenues, or similar performance measures. If the Company were to determine that the carrying amount of the goodwill exceeded its implied fair value, the Company would be required to write down the value of the goodwill on the balance sheet, adversely affecting earnings as well as capital.

Stock Performance Graph

The following graph and table compare the Company’s cumulative total return on its common stock with the cumulative total return of the Standard & Poor’s 500 (the “S&P 500”) Index and the KBW Regional Bank (the “KRX”) Index over the five-year period through December 31, 2016.  In 2015, the Company changed its stock performance graph indices from the SNL Bank and Thrift and SNL Western Bank Indices to the S&P 500 Index and the KRX Index. The KRX Index was used to further align EWBC with those companies of a relatively similar size. The S&P 500 Index was utilized as a benchmark against performance. The S&P 500 Index is a commonly referenced U.S. equity benchmark consisting of leading companies from different economic sectors. The KRX Index seeks to reflect the performance of banks and thrifts that are publicly traded in the U.S. and is composed of approximately 50 companies. The graph and table below assume that on December 31, 2011, $100 was invested in EWBC’s common stock, the S&P 500 Index and the KRX Index, and that all dividends were reinvested. Historical stock price performance shown on the graph is not necessarily indicative of future price performance.  The information set forth under the heading “Stock Performance Graph” shall not be deemed “soliciting material” or to be “filed” with the Commission, except to the extent the Company specifically requests that such information be treated as soliciting material or specifically incorporates it by reference into a filing under the Exchange Act, or the Securities Act of 1933, as amended.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion provides information about the results of operations, financial condition, liquidity, and capital resources of East West and its wholly-owned subsidiaries, East West Bank and subsidiaries (referred to herein as “East West Bank” or the “Bank”) and East West Insurance Services, Inc. This information is intended to facilitate the understanding and assessment of significant changes and trends related to the Company’s financial condition and the results of operations. This discussion and analysis should be read in conjunction with the Consolidated Financial Statements and the accompanying notes presented elsewhere in this report.

Overview

The Company’s vision is to serve as the financial bridge between the U.S. and Greater China. The Company’s primary strategy to achieve this vision is to expand the Company’s global network of contacts and resources to better meet its customers’ diverse financial needs in and between the world’s two largest markets. With over 130 locations in the U.S. and Greater China, and a full range of cross-border products and services, the Company is well equipped to fulfill its customers’ business needs.

Financial Highlights

The Company successfully completed another year with strong earnings and financial results for the year ended December 31, 2016, achieving healthy growth and an increase in revenues. It is the Company’s priority to focus on strengthening its risk management infrastructure, compliance, and the BSA/AML programs in order to meet increasing regulatory expectations, while still providing strong return to stockholders.

Noteworthy items on the Company’s performance included:

• Net income totaled $431.7 million for the year ended December 31, 2016, which reflected an increase of $47.0 million or 12%, compared to the same period in 2015.

• Diluted earnings per share was $2.97 for the year ended December 31, 2016, which reflected an increase of $0.31 or 12%, compared to the same period in 2015.

• Revenue, the sum of net interest income and noninterest income (loss), before provision for credit losses, increased $81.7 million or 7% to $1.22 billion for the year ended December 31, 2016, compared to the same period in 2015.

• Noninterest expense increased $75.0 million or 14% to $615.9 million for the year ended December 31, 2016, compared to the same period in 2015.

• The Company’s effective tax rate for the year ended December 31, 2016 was 24.6%, compared to 33.5% for the same period in 2015. The decrease in the effective tax rate was primarily attributable to additional tax credit investments in 2016, compared to 2015.

• Return on average assets increased three basis points to 1.30% for the year ended December 31, 2016, compared to the same period in 2015. Return on average equity increased 32 basis points to 13.06% for the year ended December 31, 2016, compared to the same period in 2015.

• Cost of funds improved three basis points to 0.36% for the year ended December 31, 2016, compared to the same period in 2015.

Additionally, the Company experienced growth of total assets of $2.44 billion or 8% to $34.79 billion as of December 31, 2016, compared to $32.35 billion as of December 31, 2015. This increase was primarily attributable to the increases in gross loans held-for-investment, cash and cash equivalents and securities purchased under resale agreements (“resale agreements”), partially offset by a decrease in available-for-sale investment securities.

Gross loans held-for-investment increased $1.86 billion or 8% to $25.50 billion as of December 31, 2016, compared to $23.64 billion as of December 31, 2015, while the allowance for loan losses to loans held-for-investment ratio as of December 31, 2016 declined by 10 basis points to 1.02% compared to 1.12% as of December 31, 2015 as credit quality continued to improve. The overall balance sheet growth was primarily fueled by solid deposit growth during the year ended December 31, 2016. Deposits increased $2.42 billion or 9% to $29.89 billion as of December 31, 2016 compared to $27.48 billion as of December 31, 2015, primarily due to a $3.42 billion or 16% increase in core deposits to $24.28 billion as of December 31, 2016, partially offset by a $1.00 billion or 15% decrease in time deposits to $5.62 billion as of December 31, 2016. Core deposits accounted for 81% and 76% of total deposits as of December 31, 2016 and 2015, respectively.

28

From a capital management perspective, the Company continued to maintain a strong capital position with its CET1 capital ratio at 10.9% as of December 31, 2016, compared to 10.5% as of December 31, 2015. The total risk-based capital ratios were 12.4% and 12.2% as of December 31, 2016 and 2015, respectively. The Tier I leverage capital ratio was 8.7% as of December 31, 2016, compared to 8.5% as of December 31, 2015. Book value per common share increased $2.08 or 10% to $23.78 as of December 31, 2016 from $21.70 as of December 31, 2015.

The strong balance sheet growth and increased revenues positioned the Company well to focus on its bridge banking strategy and target future growth opportunities. The Company continued to provide stockholders with healthy returns on their investment by maintaining the $0.20 quarterly dividend during 2016. As the Company remains focused on its continued growth, the Company continues to meet its customers’ financial needs. In January 2017, the Company’s Board declared first quarter dividends for the Company’s common stock. The common stock cash dividend of $0.20 per share was paid on February 15, 2017 to stockholders of record on February 1, 2017.

Results of Operations

Net income for the year ended December 31, 2016 was $431.7 million compared to $384.7 million and $345.9 million for the same period in 2015 and 2014, respectively. The Company has successfully increased net income for seven consecutive years. The 2016 earnings performance reflected the Company’s continued focus on its growth and efforts in achieving business excellence. The results of operations for the year ended December 31, 2016 benefited from improved revenue from diverse sources and a lower effective tax rate, which was partially offset by a higher noninterest expense.

Revenue, the sum of net interest income and noninterest income (loss), before provision for credit losses, was $1.22 billion for the year ended December 31, 2016, an increase of $81.7 million or 7% from $1.13 billion for the same period in 2015. The increase was mainly due to higher interest income from strong loan growth. Revenue for the year ended December 31, 2015 was $1.13 billion, an increase of $104.7 million or 10% from $1.03 billion for the same period in 2014. The increase was primarily due to the reduction in expenses related to changes in the FDIC indemnification asset and receivable/payable. This decrease was largely due to the expiration of the UCB non-single-family shared-loss agreement in 2014 and the early termination of the remaining shared-loss agreements in 2015.

Income tax expense was $140.5 million, $194.0 million, and $101.1 million for the years ended December 31, 2016, 2015, and 2014, respectively. The effective tax rate was 24.6%, 33.5%, and 22.6% for the years ended December 31, 2016, 2015, and 2014, respectively. The fluctuation of the effective tax rate year over year was mainly attributable to the tax credits recognized from investments in historic rehabilitation and renewable energy projects.

Noninterest expense was $615.9 million for the year ended December 31, 2016, an increase of $75.0 million or 14% from $540.9 million for the same period in 2015. The increase was mainly due to higher amortization of tax credit and other investments from additional tax credit investments placed into service for the year ended December 31, 2016, and higher compensation and employee benefits in support of business expansion and regulatory compliance requirements for the year ended December 31, 2016. Noninterest expense increased slightly to $540.9 million for the year ended December 31, 2015 from $533.0 million for the same period in 2014.

Return on average assets increased three basis points to 1.30% for the year ended December 31, 2016, compared to 1.27% for the same period in 2015; and also increased two basis points to 1.27% for the year ended December 31, 2015, compared to 1.25% for the same period in 2014. The return on average equity increased 32 basis points to 13.06% for the year ended December 31, 2016, compared to 12.74% for the same period in 2015; and increased two basis points to 12.74% for the year ended December 31, 2015, compared to 12.72% for the same period in 2014. The strong returns on average assets and average equity reflected the Company’s ability to achieve higher profitability while expanding the loan and deposit base.

Net Interest Income

The Company’s primary source of revenue is net interest income, which is the difference between interest earned on loans, investment securities and other interest-earning assets less interest expense on customer deposits, securities sold under repurchase agreements (“repurchase agreements”), long-term debt and other interest-bearing liabilities. Net interest margin is calculated by dividing gross interest revenue less gross interest expense by average interest-earning assets. Net interest income and net interest margin are affected by several factors, including changes in average balances and composition of interest-earning assets and funding sources, market interest rate fluctuations and slope of the yield curve, repricing characteristics and maturity of interest-earning assets and interest-bearing liabilities, volume of noninterest-bearing sources of funds and asset quality.

Net interest income for the year ended December 31, 2016 was $1.03 billion, an increase of $82.2 million or 9% compared to $950.4 million for the same period in 2015. The increase in net interest income was primarily due to higher interest income from strong loan growth during 2016. Net interest margin was 3.30% for the year ended December 31, 2016, a five basis points decrease from 3.35% in 2015. The decrease in net interest margin was primarily due to a reduction of eight basis points in loan yields from 4.35% for the year ended December 31, 2015 to 4.27% for the year ended December 31, 2016. The decrease in loan yields was primarily due to the lower accretion income from the loans accounted for under Accounting Standards Codification (“ASC”) 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (“ASC 310-30”). For the year ended December 31, 2016, total accretion income from the loans accounted for under ASC 310-30 was $45.4 million compared to $61.3 million for the same period in 2015.

30

Net interest income for the year ended December 31, 2015 was $950.4 million, a decrease of $90.4 million or 9% compared to $1.04 billion for the same period in 2014. Net interest margin was 3.35% for the year ended December 31, 2015, a decrease of 68 basis points from 4.03% for the year ended December 31, 2014. The decreases in net interest income and net interest margin were primarily due to the decreases in interest income and yields on loans as a result of lower accretion income associated with the loans acquired from the FDIC-assisted acquisitions of UCB and WFIB, partially offset by a reduction in interest expense on repurchase agreements that were paid off during 2015.

For the year ended December 31, 2016, average interest-earning assets increased $2.91 billion or 10% to $31.30 billion from $28.39 billion for the same period in 2015. The increase was primarily due to a $1.98 billion or 9%increase in average loan balances to $24.26 billion for the year ended December 31, 2016, compared to $22.28 billion for the same period in 2015. For the year ended December 31, 2015, average interest-earning assets increased by $2.59 billion or 10% to $28.39 billion from $25.80 billion for the year ended December 31, 2014. The increase was primarily due to an increase in average loan balances of $1.92 billion or 9% to $22.28 billion for the year ended December 31, 2015, compared to $20.35 billion for the same period in 2014.

Customer deposits are an important source of low-cost funding affecting both net interest income and net interest margin. Average deposits which consist of noninterest-bearing demand, interest-bearing checking, money market, saving and time deposits, increased by $2.74 billion or 11% to $28.50 billion for the year ended December 31, 2016, compared to $25.76 billion for the same period in 2015. Average deposits increased by $2.82 billion or 12% to $25.76 billion for the year ended December 31, 2015, compared to $22.94 billion for the same period in 2014.

The ratio of average noninterest-bearing demand deposits to total average deposits increased from 31% as of December 31, 2015 to 33% as of December 31, 2016. Cost of deposits was 0.30% for the year ended December 31, 2016. Cost of deposits remained stable at 0.29% for each of the years ended December 31, 2015 and 2014. Average loans were 117% funded by average deposits for the year ended December 31, 2016, which was higher than the funding level of 116% and 113% for the same periods in 2015 and 2014, respectively.

The decrease was primarily due to the decreases in net gains on sales of available-for-sale investment securities and loans, partially offset by a reduction in expenses related to changes in FDIC indemnification asset and receivable/payable. Noninterest income increased by $195.1 million to $183.4 million for the year ended December 31, 2015 compared to noninterest loss of $11.7 million for the same period in 2014. The increase was primarily due to a reduction in expenses related to changes in FDIC indemnification asset and receivable/payable and an increase in net gains on sales of available-for-sale investment securities.

The following discussion provides the composition of the major changes in noninterest income (losses) and the factors contributing to the changes.

Net gains on sales of available-for-sale investment securities decreased by $30.0 million or 74% to $10.4 million for the year ended December 31, 2016, compared to $40.4 million for the same period in 2015. Net gains on sales of available-for-sale investment securities increased by $29.7 million or 277% to $40.4 million for the year ended December 31, 2015, compared to $10.7 million for the same period in 2014. The larger net gains on sales of available-for-sale investment securities recognized during the year ended December 31, 2015, compared to December 31, 2016 and 2014, was primarily due to $21.7 million of gains realized from the sale of non-investment grade corporate debt securities, which had a $112.3 million of other-than-temporary impairment (“OTTI”) losses recorded prior to December 31, 2015 and 2014.

Net gains on sales of loans for the year ended December 31, 2016 totaled $6.1 million, compared to $24.9 million and $39.1 million for the same periods in 2015 and 2014, respectively. The net gains included valuation adjustments of $5.6 million and $3.0 million to carry loans held-for-sale at lower of cost or fair value for the years ended December 31, 2016 and 2015, respectively. No valuation adjustment was recorded for the same period in 2014. See Item 7. MD&A — Total Loan Portfolio for details.

During the year ended December 31, 2015, the Company reached an agreement with the FDIC to early terminate the UCB and WFIB shared-loss agreements. There were no remaining shared-loss agreements with the FDIC as of December 31, 2015. As a result, there was no expense related to the changes in FDIC indemnification asset and receivable/payable for the year ended December 31, 2016, compared to $38.0 million and $201.4 million of expenses for the same period in 2015 and 2014, respectively.

Noninterest Expense

Noninterest expense totaled $615.9 million for the year ended December 31, 2016, an increase of $75.0 million or 14%, compared to $540.9 million for the same period in 2015. The increase for the year ended December 31, 2016 compared to the same period in 2015 was primarily due to higher amortization of tax credit and other investments, compensation and employee benefits, and other real estate owned (“OREO”) expense (income). This increase was partially offset by the fact that there were no repurchase agreements’ extinguishment costs incurred for the year ended December 31, 2016 and lower legal expense. Noninterest expense totaled $540.9 million for the year ended December 31, 2015, an increase of $7.9 million or 1%, compared to $533.0 million for the same period in 2014. The increase for the year ended December 31, 2015 compared to the same period in 2014 was primarily due to higher compensation and employee benefits and extinguishment costs related to repurchase agreements, which was partially offset by lower legal expenses.

The following table presents the various components of noninterest expense for the periods indicated: 

	Year Ended December 31,
($ in millions)	2016		2015			2014

Repurchase agreements’ extinguishment costs	—		21.8			—
Total noninterest expense	$	615.9	$	540.9		$	533.0

Compensation and employee benefits increased by $37.9 million or 14% to $300.1 million for the year ended December 31, 2016, compared to $262.2 million for the same period in 2015. The increase was primarily attributable to the increased headcount to support the Company’s growing business and to enhance the Company’s risk management programs. For the year ended December 31, 2015, compensation and employee benefits increased by $30.4 million or 13% to $262.2 million, compared to $231.8 million for the same period in 2014. The increase was primarily due to an increase in headcount due to the growth that the Company experienced.

The amortization of tax credit and other investments increased by $47.3 million or 131% to $83.4 million for the year ended December 31, 2016, compared to $36.1 million for the same period in 2015. The increase was primarily due to additional tax credit investments that were placed into service during 2016. For the year ended December 31, 2015, amortization of tax credit and other investments decreased by $8.0 million or 18% to $36.1 million, compared to $44.1 million for the same period in 2014. This decrease was primarily due to a reduction in tax credit investments that were placed into service during 2015 compared to 2014.

OREO expense was $1.5 million for the year ended December 31, 2016, compared to OREO income of $8.9 million for the same period in 2015. The change was mainly attributable to lower net gains on OREO sales. In comparison, OREO income increased by $5.3 million or 147% to $8.9 million for the year ended December 31, 2015 from $3.6 million for the same period in 2014. The increase was primarily due to lower expense associated with a declining OREO portfolio.

There were no extinguishment costs related to repurchase agreements for the years ended December 31, 2016 and 2014. For the year ended December 31, 2015, the Company recorded $21.8 million related to the extinguishment of higher-cost repurchase agreements of $545.0 million.

Legal expense decreased by $13.6 million or 83% to $2.8 million for the year ended December 31, 2016, compared to $16.4 million for the same period in 2015. The decrease was mainly due to a reversal of a $13.4 million legal accrual following the settlement of a lawsuit titled “F&F, LLC and 618 Investments, Inc. v. East West Bank” during the year ended December 31, 2016. For the year ended December 31, 2015, legal expense decreased by $36.6 million or 69% to $16.4 million, compared to $53.0 million for the same period in 2014. The decrease was mainly due to the fact that the amount incurred for the year ended December 31, 2014 included a $31.6 million legal accrual related to the aforementioned lawsuit. See Note 13 —Commitments, Contingencies and Related Party Transactionsto the Consolidated Financial Statements for further details of the lawsuit.

Income Taxes

Income tax expense was $140.5 million, $194.0 million, and $101.1 million for the years ended December 31, 2016, 2015 and 2014, respectively. The effective tax rates were 24.6%, 33.5% and 22.6% for the years ended December 31, 2016, 2015 and 2014, respectively. The lower effective tax rate for the year ended December 31, 2016, compared to the same period in 2015, was mainly due to more tax credits that were recognized in 2016 from investments in qualified affordable housing, historic rehabilitation and renewable energy projects. The higher effective tax rate for the year ended December 31, 2015, compared to the same period in 2014, was attributable to less tax credits that were recognized in 2015 from investments in qualified affordable housing, historic rehabilitation and renewable energy projects. The Company recognizes investment tax credits from qualified affordable housing partnerships and other tax credit investments in the year the credit arises under the flow-through method of accounting. Included in the income tax expense recognized during the years ended December 31, 2016, 2015 and 2014 was $126.2 million, $67.6 million and $85.7 million, respectively, of tax credits generated from investments in qualified affordable housing partnerships and other tax credit investments.

As of December 31, 2016 and 2015, the Company had net deferred tax assets of $129.7 million and $135.9 million, respectively. For additional details on components of net deferred tax assets, see Note 12 — Income Taxesto the Consolidated Financial Statements.

Operating Segment Results

The Company defines its operating segments based on its core strategy, and has identified three reportable operating segments: Retail Banking, Commercial Banking and Other.

The Retail Banking segment focuses primarily on retail operations through the Bank’s branch network. The Commercial Banking segment, which includes C&I and CRE, primarily generates commercial loans through the domestic commercial lending offices located in California, New York, Texas, Washington, Massachusetts, Nevada and Georgia; and the foreign commercial lending offices located in China and Hong Kong. Furthermore, the Commercial Banking segment offers a wide variety of international finance and trade services and products. The remaining centralized functions, including the treasury operations of the Company and eliminations of intersegment amounts have been aggregated and included in the “Other” segment.

Changes in the Company’s management structure or reporting methodologies may result in changes in the measurement of operating segment results. Results for prior periods are generally restated for comparability when there are changes in management structure or reporting methodologies, unless it is not deemed practicable to do so.

The Company’s internal transfer pricing process is formulated to incentivize loan and deposit growth that is consistent with the overall growth objectives, as well as to provide a reasonable and consistent basis for measurement of the business segments and product net interest margins. The Company’s internal transfer pricing assumptions and methodologies are reviewed at least annually to ensure that the process is reflective of current market conditions. 

For additional information about the Company’s segments, including information about the underlying accounting and reporting process, seeNote 19 — Business Segments to the Consolidated Financial Statements.

Retail Banking

The Retail Banking segment reported pretax income of $170.1 million for the year ended December 31, 2016, compared to $212.0 million for the same period in 2015. The decrease in pretax income for this segment for the year ended December 31, 2016 was primarily driven by an increase in noninterest expense, which was partially offset by increases in net interest income and noninterest income.

Net interest income for this segment increased $6.4 million or 1% to $459.4 million for the year ended December 31, 2016, compared to $453.0 million for the same period in 2015. The increase in net interest income was primarily due to the growth in core deposits for the segment, partially offset by lower discount accretion to interest income from the purchased credit impaired (“PCI”) loan portfolio and lower-yielding single-family residential loans, compared to loans in the portfolio during the same periods in 2015.

Noninterest income for this segment increased $5.1 million or 11% to $51.4 million for the year ended December 31, 2016, compared to $46.3 million for the same period in 2015. The increase in noninterest income was attributable to a decrease in the reduction of changes in FDIC indemnification asset and receivable/payable, as all shared-loss agreements with the FDIC were early terminated in 2015, and an increase in derivative income. The increase in noninterest income was partially offset by decreases in net gains on sales of loans and wealth management fees.

Noninterest expense for this segment increased $30.9 million or 15% to $230.5 million for the year ended December 31, 2016, compared to $199.6 million for the same period in 2015. The increase was primarily due to higher consulting expense, compensation and employee benefits, deposit insurance premiums and regulatory assessments and data processing expense.

Comparing the years ended December 31, 2015 and 2014, the Retail Banking segment reported pretax income of $212.0 million for the year ended December 31, 2015, compared to pretax income of $181.3 million for the same period in 2014. The increase of $30.7 million or 17% in earnings for this segment was due to higher noninterest income and lower provision for credit losses, partially offset by lower net interest income. Net interest income for this segment decreased $9.1 million or 2%, to $453.0 million for the year ended December 31, 2015, compared to $462.1 million for the same period in 2014. The reduction in net interest income was primarily due to lower discount accretion to interest income from the PCI loan portfolio and sale of single-family residential loans. Noninterest income for this segment increased $31.8 million or 219% to $46.3 million for the year ended December 31, 2015, compared to $14.5 million for the same period in 2014. The increase was primarily due to a decrease in the reduction of changes in FDIC indemnification asset and receivable/payable, partially offset by lower net gains on sales of loans. Noninterest expense for this segment increased $1.8 million or 1% to $199.6 million for the year ended December 31, 2015, compared to $197.8 million for the same period in 2014. The increase in noninterest expense was primarily due to higher compensation and employee benefits, partially offset by lower deposit insurance premiums and regulatory assessments.

Commercial Banking

The Commercial Banking segment reported pretax income of $377.9 million for the year ended December 31, 2016, compared to $382.2 million for the same period in 2015. The decrease of $4.3 million or 1% in pretax income for this segment was attributable to increases in noninterest expense and provision for credit losses, partially offset by increases in noninterest income and net interest income.

Net interest income for this segment increased $21.3 million or 4% to $530.9 million for the year ended December 31, 2016, compared to $509.6 million for the same period in 2015. The increase in net interest income for the year ended December 31, 2016 was due to the growth of CRE and C&I loans, partially offset by the lower discount accretion to interest income from the PCI loan portfolio.

Noninterest income for this segment increased $24.2 million or 34% to $96.0 million for the year ended December 31, 2016, compared to $71.8 million for the same period in 2015. The increase was attributable to a decrease in the reduction of changes in FDIC indemnification asset and receivable/payable, as discussed above under “Retail Banking”, and increases in ancillary loan fees, letters of credit fees and foreign exchange income, partially offset by decreases in net gains on sales of loans and derivative fees and other income.

Noninterest expense for this segment increased $13.6 million or 8% to $178.1 million for the year ended December 31, 2016, compared to $164.5 million for the same period in 2015. The increase in noninterest expense was primarily due to increases in compensation and employee benefits, OREO expense and consulting expense, partially offset by decreases in legal and loan-related expenses.

37

Comparing the years ended December 31, 2015 and 2014, the Commercial Banking segment reported pretax income of $382.2 million for the year ended December 31, 2015, compared to $293.4 million for the same period in 2014. The increase of $88.8 million or 30% in earnings for this segment was due to an increase in noninterest income and decreases in noninterest expense and provision for credit losses, partially offset by a decrease in net interest income. Net interest income for this segment decreased $86.8 million or 15%, to $509.6 million for the year ended December 31, 2015, compared to $596.4 million for the same period in 2014. The decrease in net interest income was primarily due to lower discount accretion to interest income from the PCI loan portfolio. Noninterest income for this segment increased $135.7 million or 212%, to income of $71.8 million for the year ended December 31, 2015, compared to a noninterest loss of $63.9 million for the same period in 2014. The increase was primarily due to a decrease in the reduction of changes in FDIC indemnification asset and receivable/payable and higher net gains on sales of loans. Noninterest expense for this segment decreased $24.9 million or 13%, to $164.5 million for the year ended December 31, 2015, compared to $189.4 million for the same period in 2014. The decrease in noninterest expense was largely attributed to a decrease in legal expense, partially offset by an increase in compensation and employee benefits.

Other

The Other segment reported pretax income of $24.2 million for the year ended December 31, 2016, compared to pretax loss of $15.5 million for the same period in 2015. The increase in pretax income for this segment for the year ended December 31, 2016 was driven by an increase in net interest income, partially offset by a decrease in noninterest income and an increase in noninterest expense.

Net interest income for this segment increased $54.5 million to $42.3 million for the year ended December 31, 2016, compared to a net interest loss of $12.2 million for the same period in 2015. The Other segment includes the activities of the treasury function, which is responsible for the liquidity and interest rate risk management of the Company, and supports the Retail Banking and Commercial Banking segments through internal transfer pricing credits and charges, which are included in net interest income. The increase in net interest income for the year ended December 31, 2016 was primarily due to an increase in interest income from investment securities and resale agreements, a decrease in interest expense on repurchase agreements, and a reduction in net transfer pricing paid.

Noninterest income for this segment decreased $29.8 million or 46% to $35.5 million for the year ended December 31, 2016, compared to $65.3 million recorded for the same period in 2015. The decrease in noninterest income for the year ended December 31, 2016 was primarily due to lower net gains on sales of available-for-sale investment securities.

Noninterest expense for this segment increased $30.5 million or 17% to $207.3 million for the year ended December 31, 2016, compared to $176.8 million for the same period in 2015. This increase was primarily due to higher amortization of tax credit and other investments and compensation and employee benefits, partially offset by repurchase agreements’ extinguishment costs incurred in 2015 and lower consulting expense.

Comparing the years ended December 31, 2015 and 2014, the Other segment reported pretax loss of $15.5 million for 2015, compared to pretax loss of $27.7 million for 2014. The decrease in losses was due to lower net interest loss and higher noninterest income, partially offset by an increase in noninterest expense. Net interest loss for this segment decreased $5.4 million or 31%, to $12.2 million for the year ended December 31, 2015, compared to $17.6 million for the same period in 2014. Noninterest income for this segment increased $27.6 million or 73%, to $65.3 million for the year ended December 31, 2015, compared to $37.7 million for the same period in 2014.

Balance Sheet Analysis

Total assets increased $2.44 billion or 8% to $34.79 billion as of December 31, 2016, compared to $32.35 billion as of December 31, 2015. The increase in total assets was primarily attributable to the increases of $1.86 billion or 8% in net loans held-for-investment, $517.6 million or 38% in cash and cash equivalents, $400.0 million or 25% in resale agreements and $144.0 million in the held-to-maturity investment security, partially offset by a decrease of $437.4 million or 12% in available-for-sale investment securities.

The $1.86 billionincrease in net loans held-for-investment was primarily driven by growth in the loan portfolio, mainly from increases of $649.0 million in C&I loans, $590.8 million in CRE loans, $501.4 million in residential loans and $118.2 million in consumer loans. The $517.6 millionincrease in cash and cash equivalents was largely due to cash inflow versus outflows from fundings, payments and cash requirements related to normal operating activities. The $400.0 millionincrease in resale agreements was due to $1.55 billion of purchases of resale agreements, partially offset by $1.50 billion of paydowns and maturities of resale agreements during the year ended December 31, 2016. The increase was also due to a $350.0 million decrease in resale and repurchase agreements that were eligible for netting as of December 31, 2016 compared to December 31, 2015. The $144.0 million increase in held-to-maturity investment security was the result of a securitization of multifamily real estate loans entered into by the Company during the first quarter of 2016. The $437.4 milliondecrease in available-for-sale investment securities was largely due to decreases of $494.0 million in U.S. government agency and U.S. government sponsored enterprise debt securities and $278.0 million in U.S. Treasury securities, partially offset by increases of $294.1 million in foreign bonds and $176.5 million in U.S. government agency and U.S. government sponsored enterprise mortgage-backed securities.

Total liabilities increased $2.13 billion or 7% to $31.36 billion as of December 31, 2016, compared to $29.23 billion as of December 31, 2015. The increase in total liabilities funded the asset growth. This net increase was primarily attributable to the increases of $2.42 billion or 9% in customer deposits and $350.0 million in repurchase agreements, partially offset by a decrease of $697.8 million or 68% in FHLB advances.

Total customer deposits grew to $29.89 billion as of December 31, 2016, largely due to increases in noninterest-bearing demand deposits of $1.53 billion, money market deposits of $1.24 billion, and savings and interest-bearing checking accounts of $647.6 million. Such increases in customer deposits were partially offset by a decrease in time deposits of $1.00 billion as a result of reductions in public deposits. The $350.0 millionincrease in repurchase agreements was due to a $350.0 milliondecrease in resale and repurchase agreements that were eligible for netting as of December 31, 2016 compared to December 31, 2015 as discussed in the preceding paragraph. The $697.8 million decrease in FHLB advances was primarily due to the repayment of $700.0 million of short-term FHLB advances which matured in the first quarter of 2016.

Total stockholders’ equity increased $304.8 million or 10% to $3.43 billion as of December 31, 2016, compared to $3.12 billion as of December 31, 2015. This increase was primarily due to changes in net income after common stock dividends paid.

The following discussion provides additional information about the major components of the Consolidated Balance Sheet.

Investment Securities

Income from investment securities provides a significant portion of the Company’s total income, primarily from available-for-sale investment securities. The Company aims to maintain an investment portfolio, which consists of high quality and liquid securities with relatively short durations to minimize overall interest rate and liquidity risk. The Company’s available-for-sale investment securities provide:

• interest income for earnings and yield enhancement;

• availability for funding needs arising during the normal course of business;

• the ability to execute interest rate risk management strategies due to changes in economic or market conditions which influence loan origination demand, prepayment speeds, or deposit balances and mix; and

• collateral to support pledging agreements as required and/or to enhance the Company’s borrowing capacity.

Held-to-maturity security

During the first quarter of 2016, the Company securitized $201.7 million of multifamily loans and retained $160.1 million of the senior tranche of the resulting securities from the securitization as held-to-maturity, which is carried at amortized cost. The held-to-maturity security is a non-agency commercial mortgage-backed security maturing on April 25, 2046. Management intends to, and the Company has the ability to, hold the security to maturity.

39

Available-for-sale investment securities

The Company’s available-for-sale investment securities portfolio consists primarily of U.S. Treasury securities, U.S. government agency and U.S. government sponsored enterprise debt securities, U.S. government agency and U.S. government sponsored enterprise mortgage-backed securities, municipal securities, corporate debt securities and foreign bonds. Investments classified as available-for-sale are carried at their estimated fair values with the corresponding changes in fair values recorded in Accumulated other comprehensive loss, net of tax, as a component of Stockholders’ equity on the Consolidated Balance Sheets.

The following table provides a breakout of the amortized cost and fair value of available-for-sale investment securities by major categories as of the dates indicated:

Total fair value of available-for-sale investment securities decreased by $437.4 million or 12% to $3.34 billion as of December 31, 2016, compared with $3.77 billion as of December 31, 2015. The primary drivers of this decrease were:

• $278.0 million decrease in U.S. Treasury securities primarily due to $820.9 million of sales and $110.0 million of maturities, partially offset by $661.8 million of purchases;

• $494.0 million decrease in U.S. government agency and U.S. government sponsored enterprise debt securities primarily due to $618.9 million of securities called and $57.0 million of maturities, partially offset by $190.3 million of purchases; and

• $294.1 million increase in foreign bonds primarily due to purchases of multilateral development bank bonds of $374.9 million. These purchases were partially offset by calls of $50.0 million.

The Company recorded net gains totaling $10.4 million, $40.4 million, and $10.9 million on sales of available-for-sale investment securities for the years ended December 31, 2016, 2015, and 2014, respectively. The available-for-sale investment portfolio had net unrealized losses of $49.6 million and $10.6 million as of December 31, 2016 and 2015, respectively. The changes in the net unrealized amount were primarily attributed to an increase in interest rates. As of December 31, 2016 and 2015, available-for-sale investment securities with a fair value of $767.4 million and $873.0 million, respectively, were pledged to secure public deposits, repurchase agreements, the Federal Reserve Bank’s discount window, and for other purposes required or permitted by law.

Securities in an unrealized loss position are analyzed periodically for other-than-temporary impairment (“OTTI”). No OTTI was recognized for the years ended December 31, 2016, 2015 and 2014.

The following table presents the weighted average yields and contractual maturity distribution, excluding periodic principal payments, of the Company’s investment securities as of the periods indicated. Actual maturities of mortgage-backed securities can differ from contractual maturities as the borrowers have the right to prepay the obligations. In addition, such factors as prepayments and interest rate changes may affect the yields on the carrying values of mortgage-backed securities.

(2) Loans net of ASC 310-30 discount.

Although the loan portfolio grew 8% in 2016, the loan type composition remained relatively unchanged from December 31, 2015. The Company’s largest credit risks are concentrated in the commercial lending portfolios, comprised of C&I and CRE loans. The commercial lending portfolios comprised 72% and 73% of the total loan portfolio as of December 31, 2016 and 2015, respectively, and are discussed further below.

C&I Loans. C&I loans of $9.64 billion and $9.0 billion as of December 31, 2016 and 2015, respectively, which includes commercial business and trade finance loans, accounted for 38% of the total loan portfolio in both years, and comprises the largest sector in the lending portfolio. Over the last few years, the Company has experienced higher growth in its specialized lending verticals in industries such as entertainment, private equity, technology, health care and energy. As of December 31, 2016 and 2015, specialized lending verticals comprised approximately 37% and 31% of total C&I loans, respectively.

42

Although the C&I industry sectors in which the Company provides financing are diversified, the Company had higher concentrations in the industry sectors of wholesale trade (which includes $680.9 million and $789.8 million of trade finance loans as of December 31, 2016 and 2015, respectively), manufacturing, real estate and leasing, entertainment, and private equity. The Company’s exposures within wholesale trade are largely to U.S. domiciled companies, which import goods from Greater China for U.S. consumer consumption, many of which are based in California. The private equity loans are largely capital call lines of credit. The Company also has a syndicated loan portfolio within the C&I loan portfolio, which totaled $755.9 million and $462.1 million as of December 31, 2016 and 2015, respectively. The Company monitors concentrations within the C&I loan portfolio by customer exposure and industry classifications, setting limits for specialized lending verticals and setting diversification targets.

CRE Loans. CRE loans include income producing real estate, construction and land loans where interest rates may be fixed, variable, or hybrid. The Company focuses on providing financing to experienced real estate investors and developers who are long-time customers and have moderate levels of leverage. Loans are generally underwritten with high standards for cash flow, debt service coverage ratios, and loan-to-value ratios. Due to the nature of the Company’s geographical footprint and market presence, the Company has CRE loan concentrations in California, which comprised 74% and 75% of the CRE loan portfolio as of December 31, 2016 and 2015, respectively, where changes in the California economy and real estate values could have a significant impact on the collectability of these loans and the required level of allowance for loan losses. Approximately 19% and 20% of the CRE loans as of December 31, 2016 and 2015, respectively, are owner occupied properties, while the remaining 81% and 80% are non-owner occupied (where 50% or more of the debt service for the loan is provided by rental income) as of December 31, 2016 and 2015, respectively. Within the income producing CRE category, the Company had higher concentrations in retail and strip centers, industrial and office buildings as of December 31, 2016 and 2015.

The Company had $551.6 million of construction loans and $526.4 million of unfunded commitments as of December 31, 2016, compared to $434.6 million of construction loans and $527.4 million of unfunded commitments as of December 31, 2015. The composition of the construction portfolio as of December 31, 2016 and 2015 was largely in the financing of the construction of hotels, mixed use (residential and retail), multifamily and residential condominiums.

Residential Loans. Residential loans are comprised of single-family and multifamily loans. The Company offers first lien mortgage loans secured by one-to-four unit residential properties located in its primary lending areas. The Company offers a variety of first lien mortgage loan programs, including fixed rate conforming loans and adjustable rate mortgage (“ARM”) loans with initial fixed periods of one to five years, which adjust annually thereafter. The Company’s multifamily loan portfolio is largely comprised of loans secured by smaller multifamily properties ranging from five to 15 units, in its primary lending areas. Approximately 73% and 79% of the Company’s residential loans are concentrated in California as of December 31, 2016 and 2015. Many of the single-family residential loans within the Company’s portfolio are reduced documentation loans where a substantial down payment is required, resulting in a low loan to value ratio, typically 60% or less. These loans have historically experienced low delinquency and default rates.

Consumer Loans. Consumer loans are comprised of home equity lines of credit (“HELOCs”), auto loans, and insurance premium financing loans. As of December 31, 2016 and 2015, the Company’s HELOCs are the largest component of the consumer loan portfolio, and are secured by one-to-four unit residential properties located in its primary lending areas. The HELOCs loan portfolio is largely comprised of loans originated through a reduced documentation loan program, where a substantial down payment is required, resulting in a low loan to value ratio, typically 60% or less. The Company is in a first lien position for many of these reduced documentation HELOCs. These loans have historically experienced low delinquency and default rates.

The Company’s total loan portfolio includes originated and purchased loans. Originated and purchased loans, for which there was no evidence of credit deterioration at their acquisition date, are referred to collectively as non-purchased credit impaired (“non-PCI”) loans. Acquired loans for which there was, at the acquisition date, evidence of credit deterioration are referred to as PCI loans. PCI loans are recorded net of ASC 310-30 discount and totaled $642.4 million and $970.8 million, respectively, as of December 31, 2016 and 2015. For additional details regarding PCI loans, see Note 7 — Loans Receivable and Allowance for Credit Losses to the Consolidated Financial Statements.

The Company’s overseas offices include the branch in Hong Kong and the subsidiary bank in China. As of December 31, 2016, 2015 and 2014, loans held in the Hong Kong branch totaled $733.3 million, $694.6 million and $423.4 million, respectively. As of December 31, 2016, 2015 and 2014, loans held in the subsidiary bank in China totaled $425.3 million, $356.5 million and $271.8 million, respectively. These overseas loans are largely comprised of C&I loans to cross-border or trade finance companies. In total, these loans represent approximately 3%, 3% and 2% of total consolidated assets as of December 31, 2016, 2015 and 2014, respectively. These loans are included in the total loan portfolio table.

43

When a determination is made at the time of commitment to originate or purchase loans as held-for-investment, it is the Company’s intent to hold these loans to maturity or for the “foreseeable future,” subject to periodic review under the Company’s management evaluation processes, including asset/liability management. When the Company subsequently changes its intent to hold certain loans, the loans are transferred from the loans held-for-investment portfolio to the loans held-for-sale portfolio at the lower of cost or fair value. Transfers of loans held-for-investment to loans held-for-sale were $814.2 million for the year ended December 31, 2016. These loan transfers were comprised of C&I, multifamily residential and CRE loans. In comparison, $1.69 billion and $837.4 million of loans held-for-investment were transferred to loans held-for-sale during the years ended December 31, 2015 and 2014, respectively. These loan transfers were comprised primarily of single-family residential and C&I loans for the year ended December 31, 2015, and consumer and C&I loans for the year ended December 31, 2014. The Company recorded $1.9 million, $5.1 million and $5.2 million, respectively, in write-downs to the allowance for loan losses related to loans transferred from loans held-for-investment to loans held-for-sale for the years ended December 31,2016, 2015 and 2014.

During the year ended December 31, 2016, the Company sold or securitized $571.3 million in originated loans, which were primarily comprised of $262.9 million of multifamily loans, $175.1 million of C&I loans and $115.2 million of CRE loans, resulting in net gains of $11.5 million. During the same period, the Company also recorded $1.1 million in net gains and $641 thousand in mortgage servicing rights, and retained $160.1 million of the senior tranche of the resulting securities from the securitization of $201.7 million of multifamily residential loans. In comparison, during the year ended December 31, 2015, the Company sold $1.04 billion in originated loans, which were primarily comprised of $907.4 million of single-family residential loans and $127.7 million of C&I loans, resulting in net gains of $26.1 million. During the year ended December 31, 2014, the Company sold $68.1 million in originated loans, which were primarily comprised of $67.0 million of C&I loans, resulting in net gains of $7.2 million. Excluding the impact of the $571.3 million in originated loans sold and securitized, organic loan growth during the year ended December 31, 2016 was $2.43 billion or 10%.

From time to time, the Company purchases and sells loans in the secondary market. The Company purchased approximately $1.14 billion, $282.4 million and $865.2 million of loans during the years ended December 31, 2016, 2015 and 2014, respectively. The increase in the loans purchased in 2016, compared to 2015, was primarily due to the purchase of single-family residential loans that were made to low-to-moderate income borrowers. Other loan purchases were largely made within the Company’s syndicated loan portfolio, which is discussed above. Certain purchased loans were transferred from loans held-for-investment to loans held-for-sale and a write-down to allowance for loan losses was recorded, where appropriate. During the year ended December 31, 2016, the Company sold $259.1 million of loans in the secondary market at net gains of $188 thousand. In comparison, the Company sold $661.9 million and $1.02 billion, respectively, of loans in the secondary market during the years ended December 31, 2015 and 2014, resulting in net gains of $1.7 million and $31.9 million, respectively, during the same periods.

For the years ended December 31,2016 and 2015, the Company recorded valuation adjustments of $5.6 million and $3.0 million, respectively, in Net gains on sales of loans on the Consolidated Statements of Income to carry the loans held-for-sale portfolio at the lower of cost or fair value. No such valuation adjustment was recorded for the year ended December 31, 2014.

Non-PCI Nonperforming Assets

Non-PCI nonperforming assets are comprised of nonaccrual loans and OREO, net. Loans are placed on nonaccrual status when they become 90 days past due or when the full collection of principal or interest becomes uncertain regardless of the length of past due status. The following table presents information regarding non-PCI nonperforming assets and performing troubled debt restructurings (“TDRs”) as of the dates indicated:

($ in thousands)	December 31,
	2016			2015			2014			2013			2012

Non-PCI nonaccrual loans to loans held-for-investment	0.48		%	0.51		%	0.46		%	0.72		%	0.91		%
Allowance for loan losses to non-PCI nonaccrual loans	212.12		%	217.72		%	261.00		%	193.08		%	173.10		%

Typically, changes to nonaccrual loans period-over-period represent inflows for loans that are placed on nonaccrual status in accordance with the Company’s accounting policy, offset by reductions for loans that are paid down, charged off, sold, foreclosed, or no longer classified as nonaccrual as a result of continued performance and improvement in the borrower’s financial condition and loan repayment capabilities. Nonaccrual loans increased slightly to $122.8 million as of December 31, 2016 from $121.7 million as of December 31, 2015. Nonaccrual loans increased by $21.4 million or 21% from $100.3 million as of December 31, 2014 to $121.7 million as of December 31, 2015, mainly due to three TDR commercial loans and one commercial loan where payments are current but was placed on nonaccrual status during 2015 due to future cash flow concerns. This increase was partially offset by payoffs and principal paydowns in 2015.

As of December 31, 2016, $78.8 million or 64% of the $122.8 million non-PCI nonaccrual loans consisted of loans which were less than 90 days past due. In comparison, approximately $69.3 million or 57% of the $121.7 million non-PCI nonaccrual loans consisted of loans which were less than 90 days past due as of December 31, 2015. For additional details regarding the Company’s non-PCI nonaccrual loans policy, see Note 1 — Summary of Significant Accounting Policiesto the Consolidated Financial Statements.

TDRs may be designated as performing or nonperforming. A TDR may be designated as performing, if the loan has demonstrated sustained performance under the modified terms. The period of sustained performance may include the periods prior to modification if prior performance has met or exceeded the modified terms. A loan will remain on nonaccrual status until the borrower demonstrates a sustained period of performance, generally six consecutive months of payments.

The following table presents the performing and nonperforming TDRs by loan segments as of December 31, 2016 and 2015:

($ in thousands)	December 31,
	2016				2015
	Performing TDRs		Nonperforming TDRs		Performing TDRs		Nonperforming TDRs
CRE	$	20,145	$	14,446	$	11,530	$	8,333

Consumer	1,552		49		1,242		—
Total TDRs	$	83,238	$	38,983	$	43,743	$	53,095

Performing TDRs increased $39.5 million or 90% to $83.2 million as of December 31, 2016, primarily due to one CRE loan and three C&I loans becoming TDRs in 2016. Nonperforming TDRs decreased $14.1 million or 27% to $39.0 million as of December 31, 2016, primarily due to the charge-offs of two C&I loans and payoff of one residential loan.

The Company’s impaired loans include predominantly non-PCI loans held-for-investment on nonaccrual status and any non-PCI loans modified as a TDR, on either accrual or nonaccrual status. See Note 1 — Summary of Significant Accounting Policiesto the Consolidated Financial Statements for additional information regarding the Company’s TDRs and impaired loan policies. As of December 31, 2016, the allowance for loan losses included $12.7 million for impaired loans with a total recorded balance of $84.1 million. In comparison, the allowance for loan losses included $20.4 million for impaired loans with a total recorded balance of $86.2 million as of December 31, 2015.

The following table presents the recorded investment balances for non-PCI impaired loans as of December 31, 2016 and 2015:

Allowance for Credit Losses

Allowance for credit losses consists of allowance for loan losses and allowance for unfunded credit reserves. Unfunded credit reserves include reserves provided for unfunded lending commitments, issued commercial letters of credit and standby letters of credit (“SBLCs”) and recourse obligations for loans sold. The allowance for credit losses is increased by the provision for credit losses which is charged against current period operating results, and is increased or decreased by the amount of net recoveries or charge-offs, respectively, during the period. The allowance for unfunded credit reserves is included in Accrued expenses and other liabilities on the Consolidated Balance Sheets. Net adjustments to the allowance for unfunded credit reserves are included in Provision for credit losses on the Consolidated Statements of Income.

The Company is committed to maintaining the allowance for credit losses at a level that is commensurate with the estimated inherent loss in the loan portfolio, including unfunded credit reserves. In addition to regular quarterly reviews of the adequacy of the allowance for credit losses, the Company performs an ongoing assessment of the risks inherent in the loan portfolio. While the Company believes that the allowance for loan losses is appropriate as of December 31, 2016, future allowance levels may increase or decrease based on a variety of factors, including loan growth, portfolio performance and general economic conditions. For additional details on the Company’s allowance for credit losses, including the methodologies used, see Item 7. MD&A — Critical Accounting Policies and Estimates, Note 1 — Summary of Significant Accounting Policiesand Note 7 — Loans Receivable and Allowance for Credit Losses to the Consolidated Financial Statements.

Allowance for credit losses to loans held-for-investment	1.08		%	1.21		%	1.26		%	1.46		%	1.64		%

The generally increasing trend in the allowance for loan losses over the five years, presented above, was largely due to the overall growth in the loan portfolio. Along with the growth in loans, the credit quality of loans has improved over the years, with the allowance for loan losses to loans held-for-investment ratio showing a decreasing trend. Provision for credit losses includes provision for loan losses and unfunded credit reserves. Provision for credit losses are charged to income to bring the allowance for credit losses to a level deemed appropriate by the Company based on the factors described above. The fluctuation in the provision for credit losses is highly dependent on the historical loss rates trend along with the net charge-offs experienced during the period. The increase in provision for loan losses for the year ended December 31, 2016 compared to the year ended December 31, 2015 was reflective of the higher charge-offs and the overall loan portfolio growth. In contrast, the decrease in provision for loan losses for the year ended December 31, 2015 compared to the year ended December 31, 2014 was primarily due to an overall improvement in the historical loss rates, partially offset by the growth in the loan portfolio. The increase in net charge-offs for the year ended December 31, 2016 compared to the years ended December 31, 2015 and 2014 was primarily attributable to four larger C&I loans totaling $29.4 million in unrelated industries that had been placed on nonaccrual status before the charge-off.

 The following table presents the Company’s allocation of the allowance for loan losses by segment and the ratio of each loan segment to total loans as of the dates indicated:

($ in thousands)	December 31,

The Company maintains an allowance on non-PCI and PCI loans. Based on the Company’s estimates of cash flows expected to be collected, an allowance for the PCI loans is established, with a charge to income through the provision for loan losses.  PCI loan losses are estimated collectively for groups of loans with similar characteristics. As of December 31, 2016, the Company established an allowance of $118 thousand on $642.4 million of PCI loans. In comparison, an allowance of $359 thousand was established on $970.8 million of PCI loans as of December 31, 2015. The allowance balances for both periods were attributed mainly to the PCI CRE loans.

Deposits

Deposits are the primary source of funding of the Company. The Company offers a wide variety of deposit products to both consumer and commercial customers. As of December 31, 2016, total deposits increased by $2.42 billion or 9% to $29.89 billion, compared to $27.48 billion as of December 31, 2015. This increase was mainly attributable to robust growth in core deposits. Core deposits totaled $24.28 billion as of December 31, 2016, an increase of $3.42 billion or 16% from $20.86 billion as of December 31, 2015. Core deposits grew largely due to increases of $1.53 billion or 18% in noninterest-bearing demand deposits, $1.24 billion or 18% in money market accounts, and $647.6 million or 12% in interest-bearing checking and savings deposits. As of December 31, 2016 and 2015, core deposits comprised 81% and 76% of the total deposits, respectively, reflecting the continued investments in deposit products and capabilities as well as the strengthening of the Company’s deposit mix.

The increase in core deposits was offset by a decrease in time deposits of $1.00 billion or 15% from $6.62 billion as of December 31, 2015 to $5.62 billion as of December 31, 2016, largely due to a decrease in public time deposits.

Domestic time deposits of $100,000 or more totaled $3.77 billion, representing 13% of the total deposit portfolio as of December 31, 2016. These accounts had a weighted average interest rate of 0.70% as of December 31, 2016. The following table presents the maturity distribution of domestic time deposits of $100,000 or more: 

($ in thousands)	December 31, 2016
3 months or less	$	1,240,380
Over 3 months through 6 months	695,096
Over 6 months through 12 months	1,104,441
Over 12 months	725,634
Total	$	3,765,551

Borrowings

The Company utilizes short-term and long-term borrowings to manage its liquidity position. Borrowings include short-term borrowings, long-term FHLB advances and repurchase agreements.

During the year ended December 31, 2016, the Company’s subsidiary, East West Bank (China) Limited, entered into short-term borrowings totaling $60.1 million with interest rates ranging from 2.80% to 3.27%, maturing in 2017.

FHLB advances decreased by $697.8 million to $321.6 million as of December 31, 2016 from $1.02 billion as of December 31, 2015. The decrease was primarily due to the repayment of short-term FHLB advances of $700.0 million which matured in February 2016. As of December 31, 2016, FHLB advances had floating interest rates ranging from 0.92% to 1.27% with remaining maturities between 2.12 to 5.86 years.

Gross repurchase agreements totaled $450.0 million as of both December 31, 2016 and 2015. Resale and repurchase agreements are reported net pursuant to ASC 210-20-45, Balance Sheet Offsetting. Net repurchase agreements totaled $350.0 million as of December 31, 2016, resulting from $100.0 million of gross repurchase agreements that were eligible for netting against resale agreements. In comparison, all $450.0 million of gross repurchase agreements were eligible for netting against resale agreements, resulting in no net repurchase agreements reported as of December 31, 2015. As of December 31, 2016, gross repurchase agreements outstanding had interest rates ranging from 3.11% to 3.18% and original terms ranging between 10.0 and 16.5 years. The remaining maturity terms of the repurchase agreements range between 5.8 and 6.7 years.

Repurchase agreements are accounted for as collateralized financing transactions and recorded at the balances at which the securities were sold. The collateral for these agreements are primarily comprised of U.S. government agency and U.S. government sponsored enterprise mortgage-backed securities, U.S. Treasury securities, and U.S. government agency and U.S. government sponsored enterprise debt securities. To ensure that the market value of the underlying collateral remains sufficient, the Company monitors the fair value of collateral pledged relative to the principal amounts borrowed under repurchase agreements. The Company manages liquidity risks related to the repurchase agreements by sourcing funding from a diverse group of counterparties and entering into repurchase agreements with longer durations, when appropriate. For additional details, see Note 4—Securities Purchased Under Resale Agreements and Sold Under Repurchase Agreements to the Consolidated Financial Statements.

Long-Term Debt

The Company uses long-term debt to provide funding to acquire earning assets and enhance liquidity. Long-term debt, which consists of junior subordinated debt and a term loan, decreased $19.8 million or 10% from $206.1 million as of December 31, 2015 to $186.3 million as of December 31, 2016.  The decrease was primarily due to the quarterly repayment on the term loan, totaling $20.0 million during the year ended December 31, 2016.

The junior subordinated debt was issued in connection with the Company’s various pooled trust preferred securities offerings. Junior subordinated debt is recorded as a component of long-term debt and includes the value of the common stock issued by six wholly-owned subsidiaries in conjunction with these transactions. The junior subordinated debt totaled $146.3 million and $146.1 million as of December 31, 2016 and 2015, respectively. The junior subordinated debt had a weighted average interest rate of 2.28% and 1.89% for the years ended December 31, 2016 and 2015, respectively, and remaining maturity terms of 18 years to 21 years as of December 31, 2016. Beginning in 2016, trust preferred securities no longer qualify as Tier I capital and are limited to Tier II capital for regulatory purposes, based on Basel III Capital Rules. For further discussion, see Item 1. Business — Supervision and Regulation — Capital Requirements.

In 2013, the Company entered into a $100.0 million three-year term loan agreement. The terms of the agreement were modified in 2015 to extend the term loan maturity from July 1, 2016 to December 31, 2018, where principal repayments of $5.0 million are due quarterly. The term loan bears interest at the rate of the three-month LIBOR plus 150 basis points and the weighted average interest rate was 2.24% and 1.83% for the years ended December 31, 2016 and 2015, respectively. The outstanding balance of the term loan was $40.0 million and $60.0 million as of December 31, 2016 and 2015, respectively. For additional details, see Note 11 —FHLB Advances and Long-Term Debt to the Consolidated Financial Statements.

Related Party Transactions

In the ordinary course of business, the Company may enter into transactions with various related parties. Related party transactions were not material for the years ended December 31, 2016 and 2015.

Capital

The Company maintains an adequate capital base to support its anticipated asset growth, operating needs and credit risks and to ensure that East West and the Bank are in compliance with all regulatory capital guidelines. The Company engages in regular capital planning processes to optimize the use of available capital and to appropriately plan for future capital needs. The capital plan considers capital needs for the foreseeable future and allocates capital to both existing and future business activities. In addition, the Company conducts capital stress tests as part of its annual capital planning process. The stress tests enable the Company to assess the impact of adverse changes in the economy and interest rates on its capital base.

The Company’s stockholders’ equity increased $304.8 million or 10% to $3.43 billion as of December 31, 2016, compared to $3.12 billion as of December 31, 2015. The Company’s primary source of capital is the retention of its operating earnings. Retained earnings increased $315.1 million or 17%to $2.19 billion as of December 31, 2016, compared to $1.87 billion as of December 31, 2015. The increase was primarily due to net income of $431.7 million, reduced by $116.6 million of common stock dividends declared during the year ended December 31, 2016. In addition, common stock and additional paid-in capital increased $26.1 million or 2% primarily due to the activity in employee stock compensation plans. For other factors that contributed to the change in stockholders’ equity, refer to the Consolidated Statements of Changes in Stockholders’ Equity.

Book value was $23.78 per common share based on 144.2 million common shares outstanding at December 31, 2016, compared to $21.70 per common share based on 143.9 million common shares outstanding at December 31, 2015. The Company made a quarterly dividend payment of $0.20 per common share during the years ended December 31, 2016 and 2015.

Regulatory Capital and Ratios

The federal banking agencies have risk-based capital adequacy guidelines that are designed to reflect the degree of risk associated with a banking organization’s operations and transactions. The guidelines cover transactions that are reported on the balance sheet as well as those recorded as off-balance sheet items. In 2013, the Federal Reserve Board, FDIC, and Office of the Comptroller of the Currency issued the final Basel III Capital Rules establishing a new comprehensive capital framework for strengthening international capital standards as well as implementing certain provisions of the Dodd-Frank Act. See Item 1. Business — Supervision and Regulation — Capital Requirements for additional details. The Basel III Capital Rules became effective for the Company and the Bank on January 1, 2015 (subject to phase-in periods for certain components).

The Basel III Capital Rules require that banking organizations maintain a minimum CET1 ratio of 4.5%, a Tier I capital ratio of 6.0%, and a total capital ratio of 8.0%. Moreover, the rules that require banking organizations to maintain a capital conservation buffer of 2.5% above the capital minimums, are being phased-in over four years beginning in 2016. When fully phased-in in 2019, the banking organizations will be required to maintain a CET1 capital ratio of at least 7.0%, a Tier I capital ratio of at least 8.5%, and a total capital ratio of at least 10.5% to avoid limitations on capital distributions (including common stock dividends and share repurchases) and certain discretionary incentive compensation payments.

The Company is committed to maintaining capital at a level sufficient to assure the Company’s stockholders, customers and regulators that the Company and the Bank are financially sound. As of December 31, 2016 and 2015, both the Company and the Bank were considered “well capitalized,” and met all capital requirements on a fully phased-in basis under the Basel III Capital Rules. The following table presents the Company’s and the Bank’s capital ratios as of December 31, 2016 and 2015 under the Basel III Capital Rules and those required by regulatory agencies for capital adequacy and well capitalized classification purposes:

	Basel III Capital Rules
	December 31, 2016				December 31, 2015				Minimum Regulatory Requirements		Well Capitalized Requirements		Fully Phased- in Minimum Regulatory Requirements

The growth on the Company’s Consolidated Balance Sheets contributed to the $2.13 billion or 8%increase in risk weighted-assets from $25.23 billion as of December 31, 2015 to $27.36 billion as of December 31, 2016. As of December 31, 2016, the Company’s CET1 risk-based capital, Tier I risk-based capital, total risk-based capital ratios and Tier I leverage capital ratios were 10.9%, 10.9%, 12.4% and 8.7%, respectively, well above the well-capitalized requirements of 6.5%, 8.0%, 10.0% and 5.0%, respectively.

Regulatory Matters

The Bank entered into a Written Agreement to correct less than satisfactory BSA and AML programs detailed in a joint examination by the FRB and the DBO. The Bank also entered into a related MOU with the DBO. The Written Agreement, among other things, requires the Bank to:

• within 60 days of the Written Agreement, submit a written plan to strengthen the Board’s oversight of the Bank’s compliance with the applicable laws, rules and regulations relating to AML, including compliance with the BSA, the rules and regulations issued thereunder by the U.S. Department of Treasury, and the AML requirements of Regulation H of the Board of Governors (collectively, “BSA/AML Requirements”);

• within 60 days of the Written Agreement, submit a written revised program for compliance with all applicable BSA/AML Requirements, which, at a minimum, will include, among other things, a system of internal controls to ensure compliance with all applicable BSA/AML Requirements and controls designed to ensure compliance with all applicable requirements relating to correspondent accounts for foreign financial institutions;

• within 60 days of the Written Agreement, submit a written revised program for conducting appropriate levels of customer due diligence, including policies, procedures, and controls to ensure that the Bank collects, analyzes, and retains complete and accurate customer information for all account holders, including customers of the Bank’s foreign operations;

• within 60 days of the Written Agreement, submit an enhanced written program to reasonably ensure the identification and timely, accurate and complete reporting by the Bank of all known or suspected violations of law or suspicious transactions to law enforcement and supervisory authorities as required by applicable suspicious activity reporting laws and regulations;

• within 60 days of the Written Agreement, submit a written plan to the FRB for the full installation, testing, and activation of an effective automated transaction monitoring system to reasonably ensure the identification and timely, accurate, and complete reporting by the Bank of all known or suspected violations of law or suspicious transactions to law enforcement and supervisory authorities;

• within 30 days following completion of the customer account remediation required by the Written Agreement, engage an independent consultant to conduct a review of, and prepare a report detailing findings relating to, account and transaction activity associated with any high risk customer accounts during a six-month period in 2014 to determine whether suspicious activity involving high risk customer accounts or transactions was properly identified and reported; and

• within 60 days of the Written Agreement, submit a plan to enhance the Bank’s compliance with OFAC Regulations, including enhanced OFAC screening procedures and an improved methodology for assessing OFAC risks.

51

We believe the Bank is making progress in executing the compliance plans and programs required by the Written Agreement and MOU, although there can be no assurances that our plans and progress will be found to be satisfactory by our regulators. To date, the Bank has added significant resources to meet the monitoring and reporting obligations imposed by the Written Agreement and will continue to require significant management and third party consultant resources to comply with the Written Agreement and MOU and to address any additional findings or recommendations by the regulators. These incremental administrative and third party costs, as well as the operational restrictions imposed by the Written Agreement, may adversely affect the Bank’s results of operations.

If additional compliance issues are identified or if the regulators determine that the Bank has not satisfactorily complied with the terms of the Written Agreement, the regulators could take further actions with respect to the Bank and, if such further actions were taken, such actions could have a material adverse effect on the Bank. The operating and other conditions of the Written Agreement could lead to an increased risk of being subject to additional regulatory actions by the DBO and FRB or other government agencies, as well as additional actions resulting from future regular annual safety and soundness and compliance examinations by the federal and state regulators that downgrade the regulatory ratings of the Bank.

Off-Balance Sheet Arrangements and Aggregate Contractual Obligations

In the course of the Company’s business, the Company may enter into or be a party to transactions that are not recorded on the balance sheet and are considered to be off-balance sheet arrangements. Off-balance sheet arrangements are any contractual arrangements whereby an unconsolidated entity is a party, under which the Company has: (1) any obligation under a guarantee contract; (2) a retained or contingent interest in assets transferred to an unconsolidated entity or similar arrangement that serves as credit, liquidity or market risk support to that entity for such assets; (3) any obligation under certain derivative instruments; or (4) any obligation under a material variable interest held by the Company in an unconsolidated entity that provides financing, liquidity, market risk or credit risk support to the Company, or engages in leasing, hedging or research and development services with the Company.

Off-Balance Sheet Arrangements

As a financial service provider, the Company routinely enters into commitments to extend credit to customers, such as loan commitments, commercial letters of credit for foreign and domestic trade, SBLCs and financial guarantees. Many of these commitments to extend credit may expire without being drawn upon. The credit policies used in underwriting loans to customers are also used to extend these commitments. Under some of these contractual agreements, the Company may also have liabilities contingent upon the occurrence of certain events. The Company’s liquidity sources have been, and are expected to be, sufficient to meet the cash requirements of its lending activities. The following table presents the Company’s commitments, commercial letters of credit and SBLCs as of December 31, 2016:

($ in thousands)	Commitments Outstanding
Loan commitments	$	5,077,869
Commercial letters of credit and SBLCs	$	1,525,613

 A discussion of significant contractual arrangements under which the Company may be held contingently liable is included in Note 13—Commitments, Contingencies and Related Party Transactions to the Consolidated Financial Statements. In addition, the Company has commitments and obligations under post-retirement benefit plans as described in Note 15—Employee Benefit Plans to the Consolidated Financial Statements.

Asset Liability and Market Risk Management

Liquidity

Liquidity refers to the Company’s ability to meet its contractual and contingent financial obligations, on or off-balance sheet, as they become due. The Company’s primary liquidity management objective is to provide sufficient funding for its businesses throughout market cycles and be able to manage both expected and unexpected cash flow needs and requirements without adversely impacting the financial health of the Company. To achieve this objective, the Company analyzes its liquidity risk, maintains readily available liquid assets and accesses diverse funding sources including its stable core deposit base. The Company’s Asset/Liability Committee (“ALCO”) sets the liquidity guidelines that govern the day-to-day active management of the Company’s liquidity position. The ALCO regularly monitors the Company’s liquidity status and related management processes, and provides regular reports to the Board.

The Company maintains liquidity in the form of cash and cash equivalents, interest-bearing deposits with banks, and available-for-sale investment securities. These assets totaled $5.54 billion and $5.43 billion as of December 31, 2016 and 2015, respectively, accounting for 16% and 17% of total assets as of December 31, 2016 and 2015, respectively. Traditional forms of funding such as deposits and borrowings augment these liquid assets. Total deposits amounted to $29.89 billion as of December 31, 2016, compared to $27.48 billion as of December 31, 2015, of which core deposits comprised 81% and 76% of total deposits as of December 31, 2016 and 2015, respectively. As a means of augmenting the Company’s liquidity, the Company maintains available borrowing capacity under secured borrowing lines with the FHLB and FRB, unsecured federal funds’ lines of credit with various correspondent banks for purchase of overnight funds, and several master repurchase agreements with major brokerage companies. The Company’s available borrowing capacity with the FHLB and FRB was $5.58 billion and $3.25 billion, respectively, as of December 31, 2016. The Bank’s unsecured federal funds’ lines of credit, subject to availability, were $729.0 million with correspondent banks as of December 31, 2016. The Company believes that its liquidity sources are sufficient to meet all reasonably foreseeable short-term and intermediate-term needs.

53

During the years ended December 31, 2016, 2015 and 2014, net cash inflows from operating activities was $641.9 million, $469.6 million and $392.9 million, respectively. The $172.2 million increase in net cash inflows from operating activities from $469.6 million for the year ended December 31, 2015 to $641.9 million for the year ended December 31, 2016 was primarily due to a $47.0 million increase in net income, a $133.0 million reduction in payments related to FDIC shared-loss agreements, a $138.3 million increase in cash inflows from accrued interest receivable and other assets, partially offset by a $126.1 million decrease in non-cash charges mainly due to lower deferred tax expenses. The $76.7 million increase in net cash inflows from operating activities from $392.9 million for the year ended December 31, 2014 to $469.6 million for the year ended December 31, 2015 was mainly due to a $38.8 million increase in net income, a $307.8 million increase in non-cash charges that increased net operating cash and a $55.4 million increase in cash inflows from accrued expenses and other liabilities, partially offset by a $193.7 million decrease in net cash inflow from loans held-for-sale and a $131.7 million increase in payments related to FDIC shared-loss agreements. The $307.8 million increase in non-cash charges between 2014 and 2015 was mainly due to higher deferred tax expenses.

Net cash used in investing activities totaled $1.79 billion, $3.63 billion and $2.36 billion during the years ended December 31, 2016, 2015 and 2014, respectively. The $1.84 billion reduction in net cash used in investing activities during the year ended December 31, 2016 compared to the same period in 2015 was primarily due to a $1.53 billion increase in net cash inflows from available-for-sale investment securities and a $575.0 million decrease in net cash outflows from resale agreements, partially offset by a $192.0 million increase in net cash outflows from loans held-for-investment. The $1.27 billion increase in net cash used in investing activities during the year ended December 31, 2015 compared to the same period in 2014 was primarily due to $1.36 billion and $500.0 million increases in net cash outflows from available-for-sale investment securities and resale agreements, respectively, partially offset by a $722.3 million decrease in net cash outflows from loans held-for-investment.

During the years ended December 31, 2016, 2015 and 2014, the Company experienced net cash inflows from financing activities of $1.68 billion, $3.49 billion and $2.11 billion, respectively. Net cash inflows from financing activities of $1.68 billion in 2016 were primarily comprised of a $2.45 billion net increase in deposits, partially offset by a $700.0 million repayment in short-term FHLB advances and $115.8 million in cash dividends paid. Net cash inflows from financing activities of $3.49 billion in 2015 were primarily comprised of a $3.49 billion net increase in deposits and a $700.0 million increase in short-term FHLB advances, partially offset by $566.8 million related to the extinguishment of repurchase agreements and $115.6 million in cash dividends paid. Net cash inflows from financing activities of $2.11 billion in 2014 were primarily comprised of $2.28 billion increase in deposits, partially offset by $103.6 million in cash dividends paid.

As of December 31, 2016, the Company is not aware of any trends, events or uncertainties that had or were reasonably likely to have a material effect on its liquidity position. Furthermore, the Company is not aware of any material commitments for capital expenditures in the foreseeable future.

East West’s liquidity has historically been dependent on the payment of cash dividends by its subsidiary, East West Bank, subject to applicable statutes, regulations and special approval as discussed in Item 1. Business — Supervision and Regulation — Dividends and Other Transfers of Funds. The Bank paid $35.0 million of dividends to East West in January 2017, in addition to $100.0 million of dividends to East West during the year ended December 31, 2016. No dividend was paid for the year ended December 31, 2015. In addition, in January 2017, the Board declared a quarterly cash dividend of $0.20 per share for the Company’s common stock payable on February 15, 2017 to stockholders of record on February 1, 2017.

Interest Rate Risk Management

Interest rate risk results primarily from the Company’s traditional banking activities of gathering deposits and extending loans, and is the primary market risk for the Company. Economic and financial conditions, movements in interest rates and consumer preferences affect the difference between the interest the Company earns on interest-earning assets and pays on interest-bearing liabilities, and the level of the noninterest-bearing funding sources. In addition, changes in interest rates can influence the rate of principal prepayments on loans and speed of deposit withdrawals. Due to the pricing term mismatches and embedded options inherent in certain products, changes in market interest rates not only affect expected near-term earnings, but also the economic value of these interest-earning assets and interest-bearing liabilities. Other market risks include foreign currency exchange risk and equity price risk. These risks are not considered significant to the Company and no separate quantitative information concerning these risks is presented herein.

With oversight by the Company’s Board, the ALCO coordinates the overall management of the Company’s interest rate risk. The ALCO meets regularly and is responsible for reviewing the Company’s open market positions and establishing policies to monitor and limit exposure to market risk. Management of interest rate risk is carried out primarily through strategies involving the Company’s investment securities portfolio, loan portfolio, available funding channels and capital market activities. In addition, the Company’s policies permit the use of off-balance sheet derivative instruments to assist in managing interest rate risk.

54

The interest rate risk exposure is measured and monitored through various risk management tools which include a simulation model that performs interest rate sensitivity analysis under multiple scenarios. The model includes the Company’s loans, investment securities, resale agreements, customer deposits and borrowing portfolios, including the repurchase agreements. The financial instruments from the Company’s domestic and foreign operations, forecasted noninterest income and noninterest expense items are also incorporated in the simulation. The interest rate scenarios simulated include an instantaneous parallel shift and non-parallel shift in the yield curve. In addition, the Company also performs various simulations using alternative interest rate scenarios. The alternative interest rate scenarios include yield curve flattening, yield curve steepening, and yield curve inverting. In order to apply the assumed interest rate environment, adjustments are made to reflect the shift in the U.S. Treasury and other appropriate yield curves. The Company incorporates both a static balance sheet and a forward growth balance sheet in order to perform these evaluations. Results of these various simulations are used to formulate and gauge strategies to achieve a desired risk profile within the Company’s capital and liquidity guidelines.

The simulation model is based on the actual maturity and re-pricing characteristics of the Company’s interest-rate sensitive assets, liabilities and related derivative contracts. The modeled results are highly sensitive to the deposit decay assumptions used for deposits that do not have specific maturities. The Company uses historical regression analysis of the Company’s internal deposit data as a guide to set deposit decay assumptions. In addition, the model is also highly sensitive to certain assumptions on the correlation of the change in interest rates paid on core deposits to changes in benchmark market interest rates, commonly referred to as deposit beta assumptions. Deposit beta assumptions are based on the Company’s historical experience. The model also includes loan and investment prepayment assumptions. The loan and investment assumptions, which relate to anticipated prepayments under different interest rate environments, are based on an independent model, as well as the Company’s historical prepayment experiences.

Existing investment securities, loans, customer deposits and borrowings are assumed to roll into new instruments at a similar spread relative to benchmark interest rates and internal pricing guidelines. The assumptions applied in the model are documented and supported for reasonableness. Changes to key model assumptions are reviewed by the ALCO. Due to the sensitivity of the model results, the Company performs periodic testing to assess the impact of the assumptions. The Company also makes appropriate calibrations when necessary. Scenarios do not reflect strategies that management could employ to limit the impact as interest rate expectations change. Simulation results are highly dependent on these assumptions. To the extent actual behavior is different from the assumptions in the models, there could be a material change in interest rate sensitivity.

The following table presents the Company’s net interest income and economic value of equity (“EVE”) sensitivity at December 31, 2016 and December 31, 2015 related to an instantaneous and sustained non-parallel shift in market interest rates of 100 and 200 basis points in both directions.

Change in Interest Rates (Basis Points)	Net Interest Income    Volatility (1)				EVE Volatility (2)
	December 31, 2016		December 31, 2015		December 31, 2016		December 31, 2015
+200	22.4	%	18.5	%	12.3	%	9.8	%
+100	12.0	%	9.6	%	7.5	%	5.3	%
-100	(6.8	)%	(4.0	)%	(5.0	)%	(4.2	)%
-200	(7.5	)%	(4.6	)%	(9.3	)%	(6.9	)%

(1) The percentage change represents net interest income over 12 months in a stable interest rate environment versus net interest income in the various rate scenarios.

(2) The percentage change represents net portfolio value of the Company in a stable interest rate environment versus net portfolio value in the various rate scenarios.

55

Twelve-Month Net Interest Income Simulation

The Company’s estimated twelve-month net interest income sensitivity increased at December 31, 2016, compared to December 31, 2015, for both the upward and downward interest rate scenarios. The increase in sensitivity was primarily due to the increase in core deposits as well as the rising interest rate environment. The increases of core deposits caused the portfolio to become more interest rate sensitive, since these deposits are either noninterest-bearing demand deposits or have a low deposit beta. The rate increases in December 2016 resulted in an increased number of loans in the Company’s portfolio exceeding their contractual rate floor, which added to the interest income sensitivity of the loan portfolio.

Under most rising interest rate environments, the Company would expect some customers to move balances from demand deposits into higher interest-bearing deposit types such as money market, saving, or time deposits. The model is particularly sensitive to the assumption about the rate of such migration. The following table presents the Company’s net interest income sensitivity as of December 31, 2016 for the upward 100 basis point and upward 200 basis point interest rate scenarios assuming a $1.00 billion, $2.00 billion and $3.00 billion demand deposit migration:

Change in Interest Rates (Basis Points)	Net Interest Income Volatility
	December 31, 2016
	$1.00 Billion Migration 12 Months	$2.00 Billion Migration 12 Months	$3.00 Billion Migration 12 Months
+200	19.7%	17.0%	14.2%
+100	10.3%	8.5%	6.8%

EVEat Risk

The Company’s EVE sensitivity increased as of December 31, 2016, compared to December 31, 2015, for both upward and downward interest rate scenarios. The increase in sensitivity was primarily due to changes in the balance sheet portfolio mix. As of December 31, 2016, in simulated positive 100 basis-point and 200 basis-point interest rate scenarios, sensitivity was 7.5% and 12.3%, respectively. This compared to the simulated positive 100 basis-point and 200 basis-point interest rate scenarios as of December 31, 2015 of 5.3% and 9.8%, respectively. As of December 31, 2016, in simulated negative 100 basis-point and 200 basis-point interest rate scenarios, sensitivity was (5.0)% and (9.3)%, respectively, compared to the simulated negative 100 basis-point and 200 basis-point interest rate scenarios as of December 31, 2015 of (4.2)% and (6.9)%, respectively.

The Company’s net interest income and EVE profile as of December 31, 2016, as presented in the net interest income and EVE tables, reflects an asset sensitive net interest income position and an asset sensitive EVE position. The Company is naturally asset sensitive due to its large portfolio of rate-sensitive loans that are funded in part by noninterest-bearing and rate-stable core deposits. As a result, if there are no significant changes in the mix of assets and liabilities, net interest income increases when interest rates increase and net interest income decreases when interest rates decrease. As of December 31, 2016, the federal funds target rate was at a range of 0.50% to 0.75% compared to a range of 0.25% to 0.50% as of December 31, 2015. Further declines in interest rates are not expected to significantly reduce earning asset yield or liability costs, nor have a meaningful impact on net interest income. Given the uncertainty of the magnitude, timing and direction of future interest rate movements and the shape of the yield curve, actual results may vary from those predicted by the Company’s model.

Derivatives

It is the Company’s policy not to speculate on the future direction of interest rates or foreign currency exchange rates. However, the Company will, from time to time, enter into derivatives transactions in order to reduce its exposure to market risks, including interest rate risk and foreign currency risk. The Company believes these transactions, when properly structured and managed, may provide a hedge against inherent risk in assets or liabilities and against risk in specific transactions. Hedging transactions may be implemented using swaps, caps, floors, financial futures, forwards and options. Prior to entering into any hedging activities, the Company analyzes the costs and benefits of the hedge in comparison to alternative strategies.

56

The Company had two cancellable interest rate swap contracts with original terms of 20 years as of December 31, 2016, and seven cancellable interest rate swap contracts with original terms between 20 and 25 years as of December 31, 2015. The objective of these interest rate swaps, which were designated as fair value hedges, was to obtain low-cost floating rate funding on the Company’s brokered certificates of deposit. As of December 31, 2016, under the terms of the swap contracts, the Company received a fixed interest rate and paid a variable interest rate. As of December 31, 2016 and 2015, the notional values of the Company’s brokered certificates of deposit interest rate swaps were $48.4 million and $112.9 million, respectively. The fair values were a $6.0 million liability and a $5.2 million liability as of December 31, 2016 and 2015, respectively. The decrease in notional balance was primarily due to $63.7 million notional balances of interest rate swaps on certificates of deposit that were called during the year ended December 31, 2016.

The Company also offers various interest rate derivative products to its customers. When derivative transactions are executed with its customers, the derivative contracts are offset by paired trades with registered swap dealers. These contracts allow borrowers to lock in attractive intermediate and long term fixed rate financing while not increasing the interest rate risk to the Company. These transactions are not linked to specific Company assets or liabilities on the Consolidated Balance Sheets or to forecasted transactions in a hedge relationship and, therefore, are economic hedges and hedge accounting does not apply.  The contracts are marked to market at each reporting period and recorded with changes in fair value as part of Noninterest income (loss) on the Consolidated Statements of Income. Fair values are determined from verifiable third-party sources that have considerable experience with derivative markets. The Company provides data to the third party source for purposes of calculating the credit valuation component of the fair value measurement of client derivative contracts. As of December 31, 2016 and 2015, the Company had entered into derivative contracts with clients and offsetting derivative contracts with counterparties having notional balances totaling $7.67 billion and $6.49 billion, respectively. The Company’s net exposures to these interest rate derivative contracts as of December 31, 2016 and 2015 were a $2.4 million asset and a $110 thousand liability, respectively, due to the credit valuation component of these back-to-back interest rate swap contracts.

The Company enters into foreign exchange contracts with its customers and counterparty banks primarily for the purpose of allowing its clients to hedge transactions in foreign currencies from fluctuations in foreign exchange rates and also to allow the Company to economically hedge against foreign exchange fluctuations in certain certificates of deposit and loans that it offers to its customers that are denominated in foreign currencies. These transactions are economic hedges and the Company does not apply hedge accounting. The Company’s policies also permit taking proprietary currency positions within approved limits, in compliance with the proprietary trading exemption provided under Section 619 of the Dodd-Frank Act. The Company does not speculate in the foreign exchange markets, and actively manages its foreign exchange exposures within prescribed risk limits and defined controls. As of December 31, 2016 and 2015, the Company’s outstanding foreign exchange contracts that were not designated as hedging instruments totaled $767.8 million and $653.0 million, respectively. The fair values of the foreign exchange contracts included in Other assets and Accrued expenses and other liabilities on the Consolidated Balance Sheets totaled $11.9 million and $11.2 million, respectively, as of December 31, 2016, and $10.3 million and $9.4 million, respectively, as of December 31, 2015.

As of December 31, 2016 and 2015, the Company had two foreign exchange contracts, which were designated as net investment hedges to mitigate the risk of adverse changes in the USD - RMB exchange rate and to hedge a portion of the Company’s net investment in its subsidiary, East West Bank (China) Limited. As of December 31, 2016 and 2015, the Company’s currency hedge had notional values of $83.0 million and $86.6 million, respectively. The fair values were a $4.3 million asset and a $2.4 million asset as of December 31, 2016 and 2015, respectively. As of December 31, 2016, the contracts have a weighted average strike price of 6.745 RMB to USD and will expire in March 2017.

Additional information on the Company’s derivatives is presented inNote 1—Summary of Significant Accounting Policies, Note 3— Fair Value Measurement and Fair Value of Financial Instruments andNote 6—Derivatives to the Consolidated Financial Statements.

Critical Accounting Policies and Estimates

Significant accounting policies are described in Note 1—Summary of Significant Accounting Policies to the Consolidated Financial Statements. Some accounting policies, by their nature, are inherently subject to estimation techniques, valuation assumptions and other subjective assessments. In addition, some accounting policies require significant judgment in applying complex accounting principles to individual transactions to determine the most appropriate treatment. The Company has procedures and processes in place to facilitate making these judgments.

Certain accounting policies are considered to have critical effect on the Company’s Financial Statements in our judgment. The following is a discussion of the critical accounting policies including significant estimates. In each area, the Company has identified the most important variables in the estimation process. The Company has used the best information available to make the estimations necessary for the related assets and liabilities. Actual results could differ from the Company’s estimates, and future changes in the key variables could change future valuations and impact the results of operations.

Fair Value of Financial Instruments

In determining the fair value of financial instruments, the Company uses market prices of the same or similar instruments whenever such prices are available. The Company does not use prices involving distressed sellers in determining fair value. If observable market prices are unavailable or impracticable to obtain, then fair value is estimated using modeling techniques such as discounted cash flow analysis. These modeling techniques incorporate management’s assessments regarding assumptions that market participants would use in pricing the asset or the liability, including assumptions about the risks inherent in a particular valuation technique and the risk of nonperformance.

For a complete discussion on the Company’s fair value hierarchy of financial instruments, fair value measurement techniques and assumptions, and the impact on the Consolidated Financial Statements, see Note 3— Fair Value Measurement and Fair Value of Financial Instruments to the Consolidated Financial Statements. 

Available-for-Sale Investment Securities

The fair value of the available-for-sale investment securities are generally determined by independent external pricing service providers and/or by comparison to an average of quoted market prices obtained from independent external brokers. The Company performs a monthly analysis on the broker quotes and pricing service values received from third parties to ensure that the prices represent a reasonable estimate of the fair value. The procedures include, but are not limited to, initial and on-going review of third party pricing methodologies used for fair value measurement, review of pricing trends, and monitoring of trading volumes. The Company ensures prices received from independent brokers represent a reasonable estimate of the fair value through the use of observable market inputs including comparable trades, yield curves, spreads and, when available, market indices. As a result of this analysis, the price received from the third party is adjusted accordingly if the Company determines that there is a more appropriate fair value based upon the available market data. Prices from third party pricing services are often unavailable for securities that are rarely traded or are traded only in privately negotiated transactions. As a result, certain securities are priced via independent broker quotations which utilize proprietary models with observable market based inputs. Additionally, the majority of these independent broker quotations are non-binding.

The Company considers available information relevant to the collectability of the securities, including information about past events, current conditions, and reasonable and supportable forecasts, when developing the estimate of future cash flows in making its OTTI assessment for its portfolio of trust preferred securities. The Company considers factors such as remaining payment terms of the securities, prepayment speeds, expected defaults, the financial condition of the issuer(s), and the value of any underlying collateral.

PCI Loans

In situations where PCI loans have similar risk characteristics, PCI loans were aggregated into pools to estimate cash flows under ASC 310-30. A pool is accounted for as a single asset with a single interest rate, cumulative loss rate and cash flow expectation. The cash flows expected over the life of the pools are estimated by an internal cash flow model that projects cash flows and calculates the carrying values of the pools, book yields, effective interest income and impairment, if any, based on pool level events. Assumptions as to cumulative loss rates, loss curves and prepayment speeds are utilized to calculate the expected cash flows.

58

Allowance for Credit Losses

The Company’s methodology to determine the overall appropriateness of the allowance for credit losses is based on a classification migration model with quantitative factors and qualitative considerations. The migration model examines pools of loans having similar characteristics and analyzes their loss rates over a historical period. The Company assigns loss rates to each loan grade within each pool of loans. Loss rates derived by the migration model are based predominantly on historical loss trends that may not be entirely indicative of the actual or inherent loss potential. Additionally, the Company utilizes qualitative and environmental factors as adjusting mechanisms to supplement the historical results of the classification migration model. Qualitative and environmental factors are reflected as percentage adjustments and are added to the historical loss rates derived from the classified asset migration model to determine the appropriate allowance for each loan pool. The evaluation is inherently subjective as it requires estimates that are susceptible to revision as more information becomes available. Additionally, non-classified loans are also considered in the allowance for loan losses calculation and are factored in based on the historical loss experience adjusted for various qualitative factors.

Quantitative factors include the Company’s historical loss experience, delinquency and charge-off trends, collateral values, changes in nonperforming loans, probability of commitment usage, and other factors. Qualitative considerations include, but are not limited to, prevailing economic or market conditions, relative risk profiles of various loan segments, volume concentrations, growth trends, delinquency and nonaccrual status, problem loan trends, geographic concentrations, credit risk factors for loans outstanding to the customers, and the terms and expiration dates of the unfunded credit facilities.

As the Company adds new products, increases the complexity of the loan portfolio, and expands the geographic coverage, the Company expects to continue to enhance the methodology to keep pace with the size and complexity of the loan portfolio and the changing credit environment. Changes in any of the factors cited above could have a significant impact on the credit loss calculation. The Company believes that the methodologies currently employed continue to be appropriate given the Company’s size and level of complexity. For additional information on allowance for credit losses, see Note 7 — Loans Receivable and Allowance for Credit Losses to the Consolidated Financial Statements presented elsewhere in this report.

Goodwill Impairment

Under ASC 350, Intangibles — Goodwill and Other, goodwill is required to be allocated to reporting units and tested for impairment. The Company tests goodwill for impairment at least annually or more frequently if events or circumstances, such as adverse changes in the business, indicate that there may be justification for conducting an interim test. Impairment testing is performed at the reporting-unit level (which is the same level as the Company’s major operating segments identified in Note 19 — Business Segments to the Consolidated Financial Statements presented elsewhere in this report). The first part of the test is a comparison, at the reporting unit level, of the fair value of each reporting unit to its carrying value, including goodwill. In order to determine the fair value of the reporting units, a combined income approach and market approach is used. Under the income approach, the Company provided a net income projection and a terminal growth rate to calculate the discounted cash flows and the present value of the reporting units. Under the market approach, the fair value is calculated using the current fair values of comparable peer banks of similar size and focus. The market capitalizations and multiples of these peer banks are used to calculate the market price of the Company and each reporting unit. The fair value is also subject to a control premium adjustment, which is the cost savings that a purchase of the reporting unit could achieve by eliminating duplicative costs. Under the combined income and market approach, the value from each approach is weighted based on management’s perceived risk of each approach to determine the fair value. If the fair value is less than the carrying value, then the second part of the test is needed to measure the amount of goodwill impairment. The implied fair value of the reporting unit goodwill is calculated and compared to the actual carrying value of goodwill recorded within the reporting unit. If the carrying value of reporting unit goodwill exceeds the implied fair value of that goodwill, then the Company would recognize an impairment loss for the amount of the difference, which would be recorded as a charge against net income. For complete disclosure, see Note 9 — Goodwill and Other Intangible Assets to the Consolidated Financial Statements presented elsewhere in this report.

Income Taxes

The Company examines its Consolidated Financial Statements, its income tax provision, and its federal and state income tax returns and analyzes its tax positions, including permanent and temporary differences, as well as the major components of income and expense to determine whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. In the event a tax position is not more likely than not to be sustained by the tax authorities, a reserve is established by management.

59

A valuation allowance is established for deferred tax assets if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. A valuation allowance is established, when necessary, to reduce the deferred tax assets to the amount that is more likely than not to be realized. Management has concluded that it is more likely than not that all of the benefit of the deferred tax assets will be realized, with the exception of the deferred tax assets related to certain state net operating losses. Accordingly, a valuation allowance has been recorded for these amounts. The Company believes that adequate provisions have been made for all income tax uncertainties consistent with the standards of ASC 740-10, Income Taxes.

EAST WEST BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

East West Bancorp, Inc. (referred to herein on an unconsolidated basis as “East West” and on a consolidated basis as the “Company”) is a registered bank holding company that offers a full range of banking services to individuals and businesses through its subsidiary bank, East West Bank and its subsidiaries (“East West Bank” or the “Bank”). The Bank is the Company’s principal asset. As of December 31, 2016, the Company operated over 130 locations worldwide, included in the United States (“U.S.”) markets of California, Georgia, Massachusetts, Nevada, New York, Texas and Washington. In Greater China, the Company’s presence includes five full-service branches in Hong Kong, two in Shanghai, including one in the China (Shanghai) Pilot Free Trade Zone, Shantou and Shenzhen, and five representative offices in Beijing, Chongqing, Guangzhou, Taipei and Xiamen.

SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation — The accounting and reporting policies of the Company conform with United States Generally Accepted Accounting Principles (“U.S. GAAP”) and general practices in the banking industry. To prepare the Consolidated Financial Statements in conformity with U.S. GAAP, management must make estimates based on conditions that affect the reported amounts of assets and liabilities as of the date of the Consolidated Financial Statements and income and expenses during the reporting period and the related disclosures. Actual results could differ from those estimates. Certain items on the Consolidated Financial Statements and notes for the prior years have been reclassified to conform to the 2016 presentation.

Principles of Consolidation — The Consolidated Financial Statements include the accounts of East West and its wholly owned subsidiaries, East West Bank and East West Insurance Services, Inc. Intercompany transactions and accounts have been eliminated in consolidation. East West also has six wholly-owned subsidiaries that are statutory business trusts (the “Trusts”), one of which was the result of the acquisition of MetroCorp during the three months ended March 31, 2014, as discussed in Note 2—Business Combination to the Consolidated Financial Statements. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, the Trusts are not included on the Consolidated Financial Statements.

Cash and Cash Equivalents — Cash and cash equivalents include cash on hand, cash items in transit, cash due from the Federal Reserve Bank and other financial institutions, and federal funds sold with original maturities up to three months.

Interest-bearing Deposits with Banks — Interest-bearing deposits with banks include cash placed with other banks with original maturities greater than three months and less than one year.

Resale Agreements and Repurchase Agreements — Resale agreements are recorded at the balances at which the securities were acquired. The market values of the underlying securities collateralizing the related receivable of the resale agreements, including accrued interest, are monitored. Additional collateral may be requested by the Company from the counterparty when deemed appropriate. Repurchase agreements are accounted for as collateralized financing transactions and recorded at the balances at which the securities were sold. The Company may have to provide additional collateral for the repurchase agreements, as necessary. Collateral accepted includes securities that are not recognized on the Consolidated Balance Sheets. Collateral pledged consists of securities that are not netted on the Consolidated Balance Sheets against the related collateralized liability. Collateral accepted or pledged in resale and repurchase agreements with other financial institutions may also be sold or re-pledged by the secured party but is usually delivered to and held by the third party trustees. The Company has elected to offset resale and repurchase transactions with the same counterparty on the Consolidated Balance Sheets when it has a legally enforceable master netting agreement and when the transactions are eligible for netting under ASC 210-10-45.

Available-for-SaleInvestment Securities — The Company holds debt securities and marketable equity securities in its investment portfolio. These securities are classified as available-for-sale investment securities and reported at fair value. Unrealized gains and losses, after applicable income taxes, are reported in other comprehensive income. Amortization of premiums and accretion of discounts on available-for-sale investment securities are recorded as yield adjustments on such securities using the effective interest method. The specific identification method is used for determining cost in computing realized gains and losses on available-for-sale investment securities sold.

68

For each reporting period, all securities that are in an unrealized loss position are analyzed as part of the Company’s ongoing assessment of other-than-temporary impairment (“OTTI”). In determining whether an impairment is other than temporary, the Company considers the severity and duration of the decline in fair value, the length of time expected for recovery, the financial condition of the issuer, changes in the securities’ ratings and other qualitative factors, as well as whether the Company either plans to sell the security or it is more-likely-than-not that it will be required to sell the security before recovery of the amortized cost. If the impairment of the available-for-sale debt security is credit-related, an OTTI loss is recorded on the Consolidated Statements of Income. Otherwise, the non-credit-related impairment loss is recorded in other comprehensive income. If the Company intends to sell an available-for-sale debt security or believes it will be more-likely-than-not required to sell a security, the Company records the full amount of the impairment loss as an OTTI loss. Available-for-sale marketable equity securities are carried at fair value with net unrealized gains and losses included in other comprehensive income on an after-tax basis. If there is an other-than-temporary decline in the fair value of any individual available-for-sale marketable equity security, the cost basis is reduced and the Company reclassifies the associated net unrealized loss out of other comprehensive income with a corresponding charge to the Consolidated Statements of Income.

Loans Held-for-Sale — Loans held-for-sale are carried at lower of cost or fair value. When a determination is made at the time of commitment to originate or purchase loans as held-for-investment, it is the Company’s intent to hold these loans to maturity or for the “foreseeable future,” subject to periodic review under the Company’s management evaluation processes, including asset/liability management. When the Company subsequently changes its intent to hold certain loans, the loans are transferred from the loans held-for-investment portfolio to the loans held-for-sale portfolio at lower of cost or fair value. Loan origination fees on loans held-for-sale, net of certain costs of processing and closing the loans, are deferred until the time of sale and are included in computing gains or losses from the sales of the related loans. If the loan or a portion of the loan cannot be sold, it is subsequently transferred back into the loans held-for-investment portfolio from the loans held-for-sale portfolio at lower of cost or fair value on the transfer date. A valuation allowance is established if the fair value of such loans is lower than their cost, with a corresponding charge to noninterest income.

Loans Held-for-Investment — Loans receivable that the Company has the intent and ability to hold for the foreseeable future or until maturity are stated at their outstanding principal, reduced by an allowance for loan losses and net of deferred loan fees or costs on originated loans and unamortized premiums or discounts on purchased loans. Nonrefundable fees and direct costs associated with the origination or purchase of loans are deferred and netted against outstanding loan balances. The deferred net loan fees and costs are recognized in interest income as an adjustment to yield over the loan term using the effective interest method or straight-line method. Discounts or premiums on purchased loans are accreted or amortized to interest income using the effective interest method or straight-line method over the remaining period to contractual maturity. Interest on loans is calculated using the simple-interest method on daily balances of the principal amounts outstanding. Generally, loans are placed on nonaccrual status when they become 90 days past due. Loans are considered past due when contractually required principal or interest payments have not been made on the due dates. Loans are also placed on nonaccrual status when management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that full collection of principal or interest becomes uncertain, regardless of the length of past due status. Once a loan is placed on nonaccrual status, interest accrual is discontinued and all unpaid accrued interest is reversed against interest income. Interest payments received on nonaccrual loans are reflected as a reduction of principal and not as interest income. A loan is returned to accrual status when the borrower has demonstrated a satisfactory payment trend subject to management’s assessment of the borrower’s ability to repay the loan.

Troubled Debt Restructurings — A loan is classified as a troubled debt restructuring (“TDR”) when the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower that the Company would not otherwise consider. The concessions may be granted in various forms, including a below-market change in the stated interest rate, a reduction in the loan balance or accrued interest, an extension of the maturity date with a stated interest rate lower than the current market rate or note splits referred to as A/B note restructurings. In A/B note restructurings, the original note is bifurcated into A and B notes. The A note represents the portion of the modified original loan which allows for acceptable loan-to-value and debt coverage on the collateral and is expected to be collected in full. The B note represents the portion of the original loan where there is a shortfall in value and is fully charged off. The A/B note balance after the restructuring is comprised of the A note balance only, as the B note would have been charged off. A notes are not disclosed as TDRs in subsequent years after the year of restructuring, if the restructuring agreement specifies an interest rate equal to or greater than the rate that the Company was willing to accept at the time of the restructuring for a new loan with comparable risk; the loan is not impaired based on the terms specified by the restructuring agreement; and has demonstrated a period of sustained performance under the modified terms.

69

TDRs may be designated as performing or nonperforming. A TDR may be designated as performing if the loan has demonstrated sustained performance under the modified terms. The period of sustained performance may include the periods prior to modification, if prior performance has met or exceeded the modified terms. A loan will remain on nonaccrual status until the borrower demonstrates a sustained period of performance. TDRs are included in the impaired loan quarterly valuation allowance process. Refer to Impaired Loans below for a complete discussion.

Impaired Loans — The Company’s loans are grouped into heterogeneous and homogeneous (mostly consumer loans) categories. Classified loans in the heterogeneous category are identified and evaluated for impairment on an individual basis. A loan is considered impaired when, based on current information and events, it is probable that the Company will not be able to collect all scheduled payments of principal or interest due in accordance with the original contractual terms of the loan agreement. Factors considered by management in determining and measuring loan impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of and the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as appropriate, at the loan’s observable market price or the fair value of the collateral, if the loan is collateral dependent, less costs to sell. When the value of an impaired loan is less than the recorded investment and the loan is classified as nonperforming and uncollectible, the deficiency is charged off against the allowance for loan losses. If the loan is a performing TDR, the deficiency is included in the specific reserves of the allowance for loan losses, as appropriate. Payments received on impaired loans on nonaccrual status are not recognized in interest income, but are applied as a reduction to the principal outstanding. The Company’s impaired loans include predominantly non-purchased credit impaired (“non-PCI”) loans held-for-investment on nonaccrual status and any non-PCI loans modified as a TDR, on either accrual or nonaccrual status.

Allowance for Credit Losses — The allowance for credit losses consists of the allowance for loan losses and the allowance for unfunded credit reserves. Unfunded credit reserves include reserves provided for unfunded lending commitments, unissued standby letters of credit and recourse obligations for loans sold. The allowance for loan losses is established as management’s estimate of probable losses inherent in the Company’s lending activities. The allowance for loan losses is increased by the provision for loan losses and decreased by net charge-offs when management believes the uncollectability of a loan is probable. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated monthly by management based on management’s periodic review of the collectability of the loans.

The allowance for loan losses on non-PCI loans consists of specific reserves and general reserves. The Company’s non-PCI loans fall into heterogeneous and homogeneous categories. Impaired loans are subject to specific reserves. Loans in the homogeneous category, as well as non-impaired loans in the heterogeneous category, are evaluated as part of the general reserves. General reserves are calculated by utilizing both quantitative and qualitative factors. There are different qualitative risks for the loans in each portfolio segment. Predominant risk characteristics of the residential and commercial real estate (“CRE”) segments are the collateral and geographic locations of the properties collateralizing the loans. Predominant risk characteristics of the commercial and industrial (“C&I”) segment are the global cash flows of the borrowers and guarantors, as well as the economic and market conditions. Consumer loans are largely comprised of home equity lines of credit (“HELOCs”) and the predominant risk characteristic is the real estate collateral securing the loans.

The Company also maintains an allowance for loan losses on purchased credit impaired (“PCI”) loans when there is deterioration in credit quality subsequent to acquisition. Based on the Company’s estimates of cash flows expected to be collected, the Company establishes an allowance for the PCI loans, with a charge to Provision for credit losses on the Consolidated Statements of Income. 

When determined uncollectible, it is the Company’s policy to promptly charge off the difference of the outstanding loan balance and the fair value of the collateral or the discounted value of expected cash flows. Recoveries are recorded when payment is received on loans that were previously charged off through the allowance for loan losses. Allocation of a portion of the allowance to one segment of the loan portfolio does not preclude its availability to absorb losses in other segments.

70

The allowance for unfunded credit reserves is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities, including an assessment of the probability of commitment usage, credit risk factors for loans outstanding, and the terms and expiration dates of the unfunded credit facilities. The allowance for loan losses is reported separately on the Consolidated Balance Sheets, whereas the allowance for unfunded credit reserves is included in Accrued expenses and other liabilities on the Consolidated Balance Sheets. The provision for credit losses is reported on the Consolidated Statements of Income.

PCI Loans — Acquired loans are recorded at fair value as of acquisition date in accordance with ASC 805, Business Combinations. A purchased loan is deemed to be credit impaired when there is evidence of credit deterioration since its origination and it is probable at the acquisition date that the Company would be unable to collect all contractually required payments and is accounted for under ASC 310-30, Receivables — Loans and Debt Securities Acquired with Deteriorated Credit Quality. Under ASC 310-30, loans are recorded at fair value at acquisition date, factoring in credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for loan losses is not carried over or recorded as of the acquisition date.

The amount of expected cash flows over the initial investment in the loan represents the “accretable yield,” which is recognized as interest income on a level yield basis over the life of the loan. The excess of total contractual cash flows over the cash flows expected to be received at origination is deemed the “nonaccretable difference.” In estimating the nonaccretable difference, the Company (a) calculates the contractual amount and timing of undiscounted principal and interest payments (the “undiscounted contractual cash flows”) and (b) estimates the amount and timing of undiscounted expected principal and interest payments (the “undiscounted expected cash flows”). The cash flows expected over the life of the pools are estimated by an internal cash flow model that projects cash flows and calculates the carrying values of the pools, book yields, effective interest income and impairment, if any, based on pool level events. Assumptions such as cumulative loss rates, loss curves and prepayment speeds are utilized to calculate the expected cash flows. The difference between the undiscounted contractual cash flows and the undiscounted expected cash flows is the nonaccretable difference. Subsequent to the acquisition date, any increases in expected cash flows over the expected cash flows at purchase date in excess of fair value that are significant and probable are adjusted through the accretable yield on a prospective basis. Any subsequent decreases in expected cash flows over the expected cash flows at purchase date that are probable are recognized by a charge to the provision for loan losses. Any disposals of loans, including sales of loans, payments in full or foreclosures, result in the removal of the loan from the ASC 310-30 portfolio at the carrying amount.

Investments in Qualified Affordable Housing Partnerships, Tax Credit and Other Investments, Net — The Company records the investments in qualified affordable housing partnerships, net, using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the amortization on the Consolidated Statements of Income as a component of Income tax expense. The Company records investments in tax credit and other investments, net, using either the equity method or cost method of accounting. The tax credits are recognized on the Consolidated Financial Statements to the extent they are utilized on the Company’s income tax returns. The investments are reviewed for impairment on an annual basis or on an interim basis, if an event occurs that would trigger potential impairment.

Goodwill and Other Intangible Assets — Goodwill represents the excess of the purchase price over the fair value of net assets acquired in various past acquisitions. Goodwill is not amortized and is reviewed for impairment on an annual basis or on an interim basis, if an event occurs or circumstances change that would reduce the fair value of a reporting unit below its carrying value. Core deposit intangibles, which represent the intangible value of depositor relationships resulting from deposit liabilities assumed in acquisitions, are amortized over the projected useful lives of the deposits, which is typically 7 to 15 years. Core deposit intangibles are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment on goodwill and core deposit intangibles is recognized by writing down the asset as a charge to noninterest expense to the extent that the carrying value exceeds the estimated fair value.

Premises and Equipment, net — The Company’s premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed based on the straight-line method over the estimated useful lives of the various classes of assets. The ranges of estimated useful lives for the principal classes of assets are as follows:

Buildings and building improvements	25 years
Furniture, fixtures and equipment	3 to 7 years
Leasehold improvements	Term of lease or useful life, whichever is shorter

71

The Company reviews its long-lived assets for impairment annually or when events or changes in circumstances indicate that the carrying amounts of these assets may not be recoverable. An asset is considered impaired when the fair value, which is the expected undiscounted cash flows over the remaining useful life, is less than the net book value. The excess of the net book value over its fair value is charged as impairment loss to noninterest expense.

Long-Term Debt — Long-term debt consists of junior subordinated debt and a term loan. The Trusts issued both fixed and variable rate capital securities, representing undivided preferred beneficial interests in the assets of the Trusts, to third party investors. The Company is the owner of all the beneficial interests represented by the common securities of the Trusts. The purpose of issuing the capital securities was to provide the Company with a cost-effective means of obtaining Tier I capital for regulatory reporting purposes. Since the beginning of 2016, pursuant to the Basel III Capital Rules under Dodd-Frank Wall Street Reform and Consumer Protection Act, trust preferred securities have been fully phased out of Tier I capital and are now qualified as Tier II capital.

Income Taxes — The Company files consolidated federal income tax returns, foreign tax returns, and various combined and separate company state tax returns. The calculation of the Company's income tax provision and related tax accruals requires the use of estimates and judgments.

Accrued income tax liabilities (assets) represent the estimated amounts due to (receivable from) the various taxing jurisdictions where the Company has established a business presence.

Deferred tax assets and liabilities are recognized for the expected future tax consequences of existing temporary differences between the financial reporting and tax reporting basis of assets and liabilities using enacted tax laws and rates and tax carryforwards. To the extent a deferred tax asset is no longer expected more likely than not to be realized, a valuation allowance is established. See Note 12— Income Taxes for discussion of management assessment of evidence considered by the Company in establishing a valuation allowance.

The Company established an allowance for potential taxes, interest and penalties related to uncertain tax positions. This contingent reserve is estimated based on facts and circumstances, including the interpretation of existing law, new judicial or regulatory guidance, and the status of tax audits.

Stock-Based Compensation — The Company issues stock-based awards to certain employees, officers and directors, and accounts for the related costs in accordance with the provisions of ASC 505, Equity, and ASC 718, Compensation — Stock Compensation. Stock-based compensation cost is measured at the grant date based on the fair value of the awards, and expensed over the employee’s requisite service period.

The Company grants nonqualified stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”), which include service conditions for vesting. Additionally, some of the Company’s RSAs and RSUs contain performance conditions required to be met in order for the awards to vest. The stock option awards vest between three to four years from the grant date. RSAs vest ratably over three years, cliff vest after three years, or vest at a rate of 50% each at the fourth and fifth year of continued employment from the date of the grant. RSUs vest ratably over three years or cliff vest after three or five years of continued employment from the date of the grant. Compensation expense is amortized on a straight-line basis over the requisite service period for the entire award, which is generally the maximum vesting period of the award.

The fair values of stock options are estimated using the Black-Scholes option pricing model on the grant date. For time-based RSAs and RSUs, the grant-date fair values are measured at the fair value of the Company’s common stock as if the RSAs or RSUs are vested and issued on the date of grant. For performance based RSAs and RSUs, the grant date fair value considers both performance and market conditions (where applicable). As stock-based compensation expense is estimated based on awards ultimately expected to vest, it is reduced by the expense related to awards expected to be forfeited. Forfeitures are estimated at the time of grant and are reviewed annually for reasonableness. If the estimated forfeitures are revised, a cumulative effect of changes in estimated forfeitures for current and prior periods is recognized in compensation expense in the period of change.

72

EPS — Basic EPS is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during each period, plus common share equivalents calculated for stock options, warrants and RSUs outstanding using the treasury stock method. The Company has issued RSAs, which are unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents. These RSAs are considered participating securities. Accordingly, the Company applied the two-class method in the computation of basic and diluted EPS in the periods when the RSAs were outstanding. RSUs do not contain nonforfeitable rights to dividends when granted.

Derivatives — As part of the asset and liability management strategy, the Company uses derivative financial instruments to mitigate exposure to interest rate and foreign currency risks.  Derivatives utilized by the Company include swaps, forwards and option contracts.  All derivative instruments are included in Other assets or Other liabilities on the Consolidated Balance Sheets at fair value. The related cash flows are recognized on the Cash flows from operating activities section on the Consolidated Statement of Cash Flows. The Company uses its accounting hedges based on the exposure being hedged as either fair value hedges or hedges of the net investments in certain foreign operations. Changes in fair value of derivatives designated as fair value hedges are reported in Interest expense on the Consolidated Statements of Income.  Changes in fair value of derivatives used as hedges of the net investments in foreign operations, to the extent effective, are recorded as a component of AOCI. The change in fair value attributable to the ineffective portion of the hedging instrument is recognized immediately in Noninterest income on the Consolidated Statements of Income. For all other derivatives, changes in fair value are recognized on the Consolidated Statements of Income.

All derivatives designated as fair value hedges and hedges of the net investments in certain foreign operations are linked to specific hedged items or to groups of specific assets and liabilities on the Consolidated Balance Sheets.  To qualify as an accounting hedge under the hedge accounting rules (versus an economic hedge where hedge accounting is not sought), a derivative must be highly effective in offsetting the risk designated as being hedged.  The Company formally documents its hedge relationships at inception, including identification of the hedging instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction at the time the derivative contract is executed. Quarterly after the inception, the Company assesses whether the derivatives used in hedging transactions are highly effective in offsetting changes in the fair value of the hedged items.  Retroactive effectiveness is also assessed, as well as the continued expectation that the hedge will remain effective prospectively. 

The Company discontinues hedge accounting prospectively when (i) a derivative is no longer highly effective in offsetting changes in the fair value; (ii) a derivative expires or is sold, terminated, or exercised, or (iii) the Company determines that designation of a derivative as a hedge is no longer appropriate.  If a fair value hedge is discontinued, the derivative will continue to be recorded on the Consolidated Balance Sheets at its fair value with changes in fair value included on the Consolidated Statements of Income. When the hedged net investment is either sold or substantially liquidated, the effective portion of the changes in the fair value of the derivatives are reclassified out of AOCI into Foreign exchange income on the Consolidated Statements of Income.

The Company also offers various interest rate and foreign currency derivative products to customers and enters into derivative transactions in due course. These transactions are not linked to specific Company’s assets or liabilities on the Consolidated Balance Sheets or to forecasted transactions in a hedge relationship and, therefore, do not qualify for hedge accounting. The contracts are marked-to-market at the end of each reporting period with changes in fair value recorded on the Consolidated Statements of Income.

Fair Value — Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and, in many cases, requires management to make a number of significant judgments. Based on the observable inputs used in the valuation techniques, the Company classifies its assets and liabilities measured and disclosed at fair value in accordance with a three-level hierarchy (e.g., Level 1, Level 2 and Level 3) established under ASC 820, Fair Value Measurements. The Company records certain financial instruments, such as available-for-sale investment securities, and derivative assets and liabilities, at fair value on a recurring basis. Certain financial statement line items such as impaired loans, loans held-for-sale and OREO are recorded at fair value on a nonrecurring basis. Nonrecurring fair value measurements generally involve assets that are periodically evaluated for impairment. For additional information about fair value, see Note 3 — Fair Value Measurement And Fair Value Of Financial Instruments to the Consolidated Financial Statements.

73

Foreign Currency Translation — The Company revalues assets, liabilities, revenue and expense denominated in non-U.S. Dollars (“USD”) functional currencies into USD reporting currencies using applicable exchange rates. Gains and losses relating to nonfunctional currency transactions, including non-U.S. operations where the functional currency is USD, are reported on the Consolidated Statements of Income.

During the quarter ended September 30, 2015, the Company’s foreign subsidiary in China — East West Bank (China) Limited, changed its functional currency from USD to Renminbi (“RMB”). The assets and liabilities of this subsidiary are translated, for consolidation purposes, from RMB to USD reporting currency at period-end rates and generally at average rates for results of operations. Gains and losses arising from the translations are recorded in the Foreign currency translation adjustment account within AOCI in stockholders’ equity, along with any related hedged effects.

NEW ACCOUNTING PRONOUNCEMENTS ADOPTED

In February 2015, the FASB issued Accounting Standards Update (“ASU”) 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis that changes the analysis a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The amended guidance: 1) modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities; 2) eliminates the presumption that a general partner should consolidate a limited partnership; 3) affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and 4) provides a scope exception from the consolidation guidance for reporting entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a7 of the Investment Company Act of 1940 for registered money market funds. The Company adopted this amended guidance in the first quarter of 2016 and the adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

In April 2015, the FASB issued ASU 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 simplifies the presentation of debt issuance costs related to a recognized debt liability to be presented on the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The Company adopted this guidance retrospectively in the first quarter of 2016. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

In April 2015, the FASB issued ASU 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. ASU 2015-05 amends ASC 350-40 and requires the Company to determine whether a cloud computing arrangement contains a software license. If the arrangement contains a software license, the Company should account for the fees related to the software license element consistent with how the acquisitions of other software licenses are accounted for under ASC 350-40. If the arrangement does not contain a software license, the Company should account for the arrangement as a service contract. The Company adopted this guidance prospectively to all arrangements entered into or materially modified in the first quarter of 2016. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

In October 2016, the FASB issued ASU 2016-17, Consolidation (Topic 810):Interests Held through Related Parties That Are under Common Control to amend ASU 2015-02’s consolidation requirements that apply to a single decision maker’s evaluation of interests held through related parties that are under common control when it is determining whether it is the primary beneficiary of a VIE. ASU 2016-17 requires that the single decision maker considers its indirect economic interests in a VIE held through related parties that are under common control on a proportionate basis, in a manner consistent with its consideration of its indirect economic interests held through related parties that are not under common control. Entities that have adopted ASU 2015-02 are required to apply ASU 2016-17 retrospectively to all relevant prior periods beginning with the fiscal year in which ASU 2015-02 was initially applied. The Company adopted ASU 2016-17 retrospectively in the fourth quarter of 2016. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The new guidance replaced existing revenue recognition guidance for contracts to provide goods or services to customers.  ASU 2014-09 clarifies the principles for recognizing revenue and replaces nearly all existing revenue recognition guidance in U.S. GAAP. Quantitative and qualitative disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers are also required. ASU 2014-09 as amended by ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, is effective for interim and annual periods beginning after December 15, 2017 and is applied on either a modified retrospective or full retrospective basis. Early adoption is permitted for interim and annual periods beginning after December 15, 2016. The Company’s revenue is mainly comprised of net interest income from financial assets and liabilities, which is explicitly excluded from the scope of the new guidance, and noninterest income. The Company continues to evaluate the impact of ASU 2014-09 on our noninterest income and on our presentation and disclosures. The Company’s implementation efforts include the identification of revenue within the scope of ASU 2014-09 and the review is on-going.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 requires equity investments, except those accounted for under the equity method of accounting or consolidated, to be measured at fair value with changes recognized in net income. If there is no readily determinable fair value, the guidance allows entities the ability to measure investments at cost less impairment, whereby impairment is based on a qualitative assessment. The guidance eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value of financial instruments measured at amortized cost and changes the presentation of financial assets and financial liabilities on the Consolidated Balance Sheets or in the footnotes. If an entity has elected the fair value option to measure liabilities, the new accounting guidance requires the portion of the change in the fair value of a liability resulting from credit risk to be presented in other comprehensive income. The Company has not elected to measure any of its liabilities at fair value. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is not permitted except for certain specific changes under the fair value option guidance. To adopt the amendments, the Company is required to make a cumulative-effect adjustment to the consolidated balance sheet as of the beginning of the fiscal year in which the guidance is effective. However, the amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the adoption date. The Company is currently evaluating the impact on its Consolidated Financial Statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is intended to increase transparency and comparability in the accounting for lease transactions. ASU 2016-02 requires lessees to recognize all leases longer than twelve months on the Consolidated Balance Sheets as lease assets and lease liabilities and quantitative and qualitative disclosures regarding key information about leasing arrangements. Lessor accounting is largely unchanged. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years with an option to early adopt. The Company is currently evaluating the potential impact on its Consolidated Financial Statements. The Company expects a gross-up of its Consolidated Balance Sheets as a result of recognizing lease liabilities and right of use assets. The Company does not expect a material impact to its recognition of operating lease expense on its Consolidated Statements of Income.

In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships, to clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument in an existing hedging relationship would not be considered a termination of the derivative instrument or a change in a critical term of the hedging relationship provided that all other hedge accounting criteria in ASC 815 continue to be met. This clarification applies to both cash flow and fair value hedging relationships. ASU 2016-05 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years with an option to early adopt. The Company has an option to adopt the amendments of this ASU either on a prospective basis or modified retrospective basis. The adoption of this guidance will not have a material impact on the Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments that requires an entity to use a four step decision model when assessing contingent call (put) options that can accelerate the payment of principal on debt instruments to determine whether they are clearly and closely related to their debt hosts. ASU 2016-06 will be effective for interim and annual reporting periods beginning after December 15, 2016 and must be implemented using a modified retrospective basis. Early adoption is permitted. The adoption of this guidance will not have a material impact on the Consolidated Financial Statements.

75

In March 2016, the FASB issued ASU 2016-07, Investments—Equity Method and Joint Ventures (Topic 323):Simplifying the Transition to the Equity Method of Accounting, to eliminate the requirement for an investor to retroactively apply the equity method when its increase in ownership interest (or degree of influence) in an investee triggers equity method accounting. The amendments in ASU 2016-07 also require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in AOCI at the date the investment becomes qualified for use of the equity method. ASU 2016-07 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years and should be applied prospectively. Early adoption is not permitted. The adoption of this guidance will not have a material impact on the Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, to simplify several aspects of the accounting for share-based payment transactions, including the accounting for income taxes, forfeitures, statutory tax withholding requirements, as well as classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The Company has adopted ASU 2016-09 in the first quarter of 2017 and has begun recording the excess tax benefits and deficiencies within the income tax expense on a prospective basis. The Company does not expect the adoption of this guidance to have a material impact on its Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments to introduce a new approach based on expected losses to estimate credit losses on certain types of financial instruments, which modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new “expected credit loss” impairment model will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, available-for-sale and held-to-maturity (“HTM”) debt securities, net investments in leases and off-balance-sheet credit exposures. For available-for-sale debt securities with unrealized losses, ASU 2016-13 does not change the measurement method of credit losses, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models and methods for estimating the allowance for loans and lease losses and requires disclosure of the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination (i.e., by vintage year). ASU 2016-13 is effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. Earlier adoption is permitted as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. While the Company is still evaluating the impact on its Consolidated Financial Statements, the Company expects that ASU 2016-13 may result in an increase in the allowance for credit losses due to the following factors: 1) the allowance for credit losses will increase to provide for expected credit losses over the remaining expected life of the loan portfolio, and will consider expected future changes in macroeconomic conditions; 2) the nonaccretable difference on the PCI loans will be recognized as an allowance, offset by an increase in the carrying value of the PCI loans; and 3) an allowance may be established for estimated credit losses on available-for-sale and HTM debt securities. The amount of increase will be impacted by the portfolio composition and quality, as well as the economic conditions and forecasts as of the adoption date. The Company has began its implementation efforts by identifying key interpretive issues, and assessing its processes and identifying the system requirements against the new guidance to determine what modifications may be required.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, to provide guidance on the classification of certain cash receipts and payments on the consolidated statement of cash flows in order to reduce diversity in practice. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of this guidance to have a material impact on its Consolidated Financial Statements.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, whichrequires the Company to include in its cash and cash-equivalent balances in the statement of cash flows those amounts that are deemed to be restricted cash and restricted cash equivalents. In addition, the Company is required to explain the changes in the combined total of restricted and unrestricted balances in the statement of cash flows. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, where the guidance should be applied using a retrospective transition method to each period presented. Early adoption is permitted. The Company is currently evaluating the impact on its Consolidated Financial Statements.

76

In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment to simplify the accounting for goodwill impairments. An entity will no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. ASU 2017-04 also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. ASU 2017-04 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years and should be applied prospectively. Early adoption is permitted for interim or annual goodwill impairment tests with measurement dates after January 1, 2017. The Company is currently evaluating the impact on its Consolidated Financial Statements.

NOTE 2 — BUSINESS COMBINATION

On January 17, 2014, the Company completed the acquisition of MetroCorp, parent of MetroBank, N.A. and Metro United Bank. MetroCorp was headquartered in Houston, Texas and previously operated 19 branch locations within Texas and California under its two banks. The Company acquired MetroCorp to further expand its presence, primarily in Texas, within the markets of Houston and Dallas, and in California, within the San Diego market. The purchase consideration was satisfied with two-thirds in East West common stock and one-third in cash. The fair value of the consideration transferred in the acquisition of MetroCorp was $291.4 million, which consisted of 5,583,093 shares of East West common stock fair valued at $190.8 million at the date of acquisition and $89.4 million in cash, $2.4 million of additional cash to MetroCorp stock option holders and a MetroCorp warrant, fair valued at $8.8 million, assumed by the Company.

The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. At the acquisition date, the Company recorded total fair value of assets acquired and liabilities assumed of $1.70 billion and $1.41 billion, respectively. The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the January 17, 2014 acquisition date. Goodwill from the acquisition represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired and is not deductible for tax purposes. The Company recorded $121.0 million of goodwill on the acquisition date. During the three months ended December 31, 2014, the Company recorded additional tax and bank-owned life insurance adjustments of $10.3 million and $700 thousand, respectively, related to the MetroCorp acquisition, increasing goodwill to $132.0 million.    

NOTE 3 —FAIR VALUE MEASUREMENT AND FAIR VALUE OF FINANCIAL INSTRUMENTS

In determining fair value, the Company uses various methods including market and income approaches. Based on these approaches, the Company utilizes certain assumptions that market participants would use in pricing the asset or liability. These inputs can be readily observable, market corroborated or generally unobservable. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy noted below is based on the quality and reliability of the information used to determine fair value. The fair value hierarchy gives the highest priority to quoted prices available in active markets and the lowest priority to data lacking transparency. The fair value of the Company’s assets and liabilities is classified and disclosed in one of the following three categories:

•	Level 1	—	Valuation is based on quoted prices for identical instruments traded in active markets.
•	Level 2	—	Valuation is based on quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable and can be corroborated by market data.
•	Level 3	—	Valuation is based on significant unobservable inputs for determining the fair value of assets or liabilities. These significant unobservable inputs reflect assumptions that market participants may use in pricing the assets or liabilities.

In determining the appropriate hierarchy levels, the Company performs an analysis of the assets and liabilities that are subject to fair value disclosure. The Company’s assets and liabilities are classified in their entirety based on the lowest level of input that is significant to their fair value measurements.

The following tables present financial assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2016 and 2015:

At each reporting period, all assets and liabilities for which the fair value measurement is based on significant unobservable inputs are classified as Level 3. There were no assets or liabilities measured using significant unobservable inputs (Level 3) on a recurring basis for the year ended December 31, 2016. The following table presents a reconciliation of the beginning and ending balances for major asset and liability categories measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the years ended December 31, 2015, and 2014:

(1) Net gains or losses (realized and unrealized) of corporate debt securities and embedded derivative liabilities are included in Net gains on sales of available-for-sale investment securities and Other operating expense, respectively, on the Consolidated Statements of Income.

(2) Unrealized gains or losses on available-for-sale investment securities are reported in Other comprehensive (loss) income, net of tax, on the Consolidated Statements of Comprehensive Income.

Transfers into or out of fair value hierarchy classifications are made if the significant inputs used in the financial models measuring the fair values of the assets and liabilities become unobservable or observable in the current marketplace. The Company’s policy, with respect to transfers between levels of the fair value hierarchy, is to recognize transfers into and out of each level as of the end of the reporting period. There were no transfers of assets and liabilities measured on a recurring basis in and out of Level 1, Level 2 or Level 3 for the years ended December 31, 2016 and 2014. During the year ended December 31, 2015, the Company transferred $1.1 million of pooled trust preferred securities measured on a recurring basis out of Level 3 into Level 2 due to increased market liquidity and price observability. There were no transfers of assets and liabilities measured on a recurring basis between Level 1 and Level 2 during the year ended December 31, 2015.

Assets measured at fair value on a nonrecurring basis include certain non-PCI loans that were impaired, OREO and loans held-for-sale.  These fair value adjustments result from impairments recognized during the period on certain non-PCI impaired loans, application of fair value less cost to sell on OREO and application of the lower of cost or fair value valuation on loans held-for-sale.

(1) Resale and repurchase agreements are reported net pursuant to ASC 210-20-45, Balance Sheet Offsetting. As of December 31, 2015, the carrying amount of $450.0 millionof repurchase agreements was eligible for netting against resale agreements, resulting in no repurchase agreements’ balances being reported.

The following is a description of the valuation methodologies and significant assumptions used to measure financial assets and liabilities at fair value and to estimate fair value for certain financial instruments not recorded at fair value. The description also includes the level of the fair value hierarchy in which the assets or liabilities are classified.

Cash and Cash Equivalents — The carrying amount approximates fair value due to the short-term nature of these instruments. As such, the estimated fair value is classified as Level 1.

Interest-bearing deposits with banks — The fair value of interest-bearing deposits with banks generally approximates their book value due to their short maturities.  In addition, due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

Resale Agreements — The fair value of resale agreements is estimated by discounting the cash flows based on expected maturities or repricing dates utilizing estimated market discount rates.  In addition, due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

Held-to-Maturity Investment Security — The fair value of the held-to-maturity investment security is determined by the discount cash flow approach. The discount rate is derived from conditional prepayment rate, constant default rate, loss severity and discount margin. Due to the significant unobservable inputs, the held-to-maturity investment security is classified as Level 3.

Available-for-SaleInvestment Securities — When available, the Company uses quoted market prices to determine the fair value of available-for-sale investment securities; such items are classified as Level 1.  Level 1 available-for-sale investment securities mainly include U.S. Treasury securities.  The fair values of other available-for-sale investment securities are generally determined by independent external pricing service providers who have experience in valuing these securities or by the average quoted market prices obtained from independent external brokers. In obtaining such valuation information from third parties, the Company has reviewed the methodologies used to develop the resulting fair values.  The available-for-sale investment securities valued using such methods are classified as Level 2.

Loans Held-for-Sale — The Company’s loans held-for-sale are carried at the lower of cost or fair value. These loans are mainly comprised of student loans.  The fair value of loans held-for-sale is derived from current market prices and comparative current sales. As such, the Company records any fair value adjustments on a nonrecurring basis. Loans held-for-sale are classified as Level 2.

82

Non-PCI Impaired Loans — The fair value of non-PCI impaired loans is measured using the market comparables or discounted cash flow techniques. For CRE loans and C&I loans, the fair value is based on each loan’s observable market price or the fair value of the collateral less cost to sell, if the loan is collateral dependent. The fair value of collateral is generally based on third party appraisals (or internal evaluation if third party appraisal is not required by regulations) which utilize one or more valuation techniques (income, market and/or cost approaches). All third party appraisals and evaluations are reviewed and validated by independent appraisers or the Company’s appraisal department staffed by licensed appraisers and/or experienced real estate reviewers. The third party appraisals are ordered through the appraisal department (except for one-to-four unit residential appraisals which are typically ordered through an approved appraisal management company or an approved residential appraiser) at the inception, renewal or, for all real estate related loans, upon the occurrence of any event causing a downgrade to an adverse grade (i.e., “substandard” or “doubtful”). Updated appraisals and evaluations are generally obtained within the last 12 months. The Company increases the frequency of obtaining updated appraisals for adversely graded credits when declining market conditions exist. All appraisals include an “as is” market value without conditions as of the effective date of the appraisal. For certain impaired loans, the Company utilizes the discounted cash flow approach and applies a discount derived from historical data. The significant unobservable inputs used in the fair value measurement of non-PCI impaired loans are discount applied based on the liquidation cost of collateral and selling cost. On a quarterly basis, all nonperforming assets are reviewed to assess whether the current carrying value is supported by the collateral or cash flow and to ensure that the current carrying value is appropriate. Non-PCI impaired loans are classified as Level 3.

Loans Held-for-Investment, net — The fair value of loans held-for-investment other than Non-PCI impaired loans is determined based on a discounted cash flow approach considered for an exit price value. The discount rate is derived from the associated yield curve plus spreads that reflect the rates in the market for loans with similar financial characteristics. No adjustments have been made for changes in credit within any of the loan portfolios. It is management’s opinion that the allowance for loan losses pertaining to performing and nonperforming loans results in a fair value valuation of credit for such loans. Due to the unobservable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 3.

OREO — The Company’s OREO represents properties acquired through foreclosure or through full or partial satisfaction of loans held-for-investment, which are recorded at estimated fair value less the cost to sell at the time of foreclosure and at the lower of cost or estimated fair value less the cost to sell subsequent to acquisition. The fair values of OREO properties are based on third party appraisals, broker price opinions or accepted written offers. Please refer to the Non-PCI Impaired Loans section above for a detailed discussion on the Company’s policies and procedures related to appraisals and evaluations. On a monthly basis, the current fair market value of each OREO property is reviewed to ensure that the current carrying value is appropriate. The Company uses the market comparable valuation technique to measure the fair value of OREO properties. The significant unobservable input used is the selling cost. OREO properties are classified as Level 3.

Investment inFHLB Stock and Federal Reserve Bank Stock — The carrying amounts of the Company’s investments in FHLB Stock and Federal Reserve Bank Stock approximate fair value. The valuation of these investments is classified as Level 2. Ownership of these securities is restricted to member banks and the securities do not have a readily determinable fair value.  Purchases and sales of these securities are at par value.

Accrued Interest Receivable — The carrying amount approximates fair value due to the short-term nature of these instruments. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

83

Interest Rate Swaps and Options — The Company enters into interest rate swap and option contracts with institutional counterparties to hedge against interest rate swap and option products offered to bank customers. These products allow borrowers to lock in attractive intermediate and long-term interest rates by entering into an interest rate swap or option contract with the Company, resulting in the customer obtaining a synthetic fixed rate loan. The Company also enters into interest rate swap contracts with institutional counterparties to hedge against certificates of deposit issued. This product allows the Company to lock in attractive floating rate funding. The fair value of interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash payments (or receipts) and the discounted expected variable cash receipts (or payments).  The variable cash receipts (or payments) are based on the expectation of future interest rates (forward curves) derived from observed market interest rate curves.  The fair value of interest rate options is determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates fell below (rise above) the strike rate of the floors (caps).  The variable interest rates used in the calculation of projected receipts on the floor (cap) are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. In addition, to comply with the provisions of ASC 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements of its derivatives. The credit valuation adjustments associated with the Company’s derivatives utilize Level 3 inputs, model-derived credit spreads. As of December 31, 2016, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of these interest rate contracts’ positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivative portfolios. As a result, the Company classifies these derivative valuations in Level 2 of the fair value hierarchy due to the observable nature of the significant inputs utilized.

Foreign Exchange Contracts — The Company enters into short-term foreign exchange contracts to purchase/sell foreign currencies at set rates in the future.  These contracts economically hedge against foreign exchange rate fluctuations. The Company also enters into contracts with institutional counterparties to hedge against foreign exchange products offered to bank customers. These products allow customers to hedge the foreign exchange risk of their deposits and loans denominated in foreign currencies. The Company assumes minimal foreign exchange rate risk because the contracts with the customer and the institutional party mirror each other.  The fair value is determined at each reporting period based on changes in the foreign exchange rate. These are over-the-counter contracts where quoted market prices are not readily available.  Valuation is measured using conventional valuation methodologies with observable market data.  Valuation depends on the type of derivative and the nature of the underlying rate and contractual terms including period of maturity, price and index upon which the derivative’s value is based. Key inputs include foreign exchange rates (spot and/or forward rates), volatility of currencies, and the correlation of such inputs. The counterparties’ credit risks are considered nominal and resulted in no adjustments to the valuation of the foreign exchange contracts. Due to the observable nature of the inputs used in deriving the fair value of these contracts, the valuation of foreign contracts is classified as Level 2.

Customer Deposits — The fair value of deposits with no stated maturity, such as demand deposits, interest checking, savings and money market deposits, approximates the carrying amount as the amounts are payable on demand at the measurement date. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2. For time deposits, the fair value is based on the discounted value of contractual cash flows using current market rates for instruments with similar maturities. Due to the observable nature of the inputs used in deriving the estimated fair value, time deposits are classified as Level 2.

FHLB Advances — The fair value of FHLB advances is estimated based on the discounted value of contractual cash flows, using rates currently offered by the FHLB of San Francisco for advances with similar remaining maturities at each reporting date. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

Repurchase Agreements — The fair value of the repurchase agreements is calculated by discounting future cash flows based on expected maturities or repricing dates, utilizing estimated market discount rates and taking into consideration the call features of each instrument. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

Accrued Interest Payable — The carrying amount approximates fair value due to the short-term nature of these instruments. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

Long-Term Debt — The fair value of long-term debt is estimated by discounting the cash flows through maturity based on current market rates the Company would pay for new issuances. Due to the observable nature of the inputs used in deriving the estimated fair value, long-term debt is classified as Level 2.

84

Foreign currency forward contracts — The Company enters into foreign currency forward contracts to hedge its net investment in East West Bank (China) Limited, a non-USD functional currency subsidiary in China. The fair value of foreign currency forward contracts is valued by comparing the contracted foreign exchange rate to the current market exchange rate. Inputs include spot rates, forward rates, and the interest rate curve of the domestic and foreign currency. Interest rate forward curves are used to determine which forward rate pertains to a specific maturity. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

RPAs — The Company enters into RPAs, under which the Company assumes its pro-rata share of the credit exposure associated with the borrower’s performance related to interest rate derivative contracts. The fair value of RPAs is calculated by determining the total expected asset or liability exposure of the derivatives to the borrowers and applying the borrowers’ credit spread to that exposure. Total expected exposure incorporates both the current and potential future exposure of the derivatives, derived from using observable inputs, such as yield curves and volatilities. The credit spreads of the borrowers used in the calculation are estimated by the Company based on current market conditions, including consideration of current borrowing spreads for similar customers and transactions, review of existing collateralization or other credit enhancements, and changes in credit sector and entity-specific credit information. The Company has determined that the majority of the inputs used to value RPAs fall within Level 2 of the fair value hierarchy.

The fair value estimates presented herein are based on pertinent information available to management as of each reporting date. Although the Company is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date, and therefore, current estimates of fair value may differ significantly from the amounts presented herein.

NOTE 4 — SECURITIES PURCHASED UNDER RESALE AGREEMENTS AND SOLD UNDER REPURCHASE AGREEMENTS

Resale Agreements

Resale agreements are recorded at the balances at which the securities were acquired. The market values of the underlying securities collateralizing the related receivable of the resale agreements, including accrued interest, are monitored. Additional collateral may be requested by the Company from the counterparty when deemed appropriate. Gross resale agreements were $2.10 billion and $2.05 billion as of December 31, 2016 and 2015, respectively. The weighted average interest rates were 1.84% and 1.61% as of December 31, 2016 and 2015, respectively. As of December 31, 2016, total gross resale agreements that are maturing in the next five years are as follows: 2017 — $1.40 billion; 2018 — $50.0 million; 2019 — $0.0 million; 2020 — $100.0 million; 2021 — $0.0 million and thereafter — $550.0 million.

Repurchase Agreements

Long-term repurchase agreements are accounted for as collateralized financing transactions and recorded at the balances at which the securities were sold. The collateral for these agreements is primarily comprised of U.S. government agency and U.S. government sponsored enterprise mortgage-backed securities, U.S. Treasury securities, and U.S. government agency and U.S. government sponsored enterprise debt securities. The Company may have to provide additional collateral for the repurchase agreements, as necessary.

Gross repurchase agreements were $450.0 million as of both December 31, 2016 and 2015. The weighted average interest rates were 3.15% and 2.60% as of December 31, 2016 and 2015, respectively. The Company had no charges related to the extinguishment of repurchase agreements for the years ended December 31, 2016 and 2014. In comparison, the Company recorded $21.8 million of charges related to the extinguishment of $545.0 million of repurchase agreements for the year ended December 31, 2015. All of the $450.0 million in gross repurchase agreements as of December 31, 2016 mature after 2021.

85

Balance Sheet Offsetting

The Company’s resale and repurchase agreements are transacted under legally enforceable master repurchase agreements that provide the Company, in the event of default by the counterparty, the right to liquidate securities held and to offset receivables and payables with the same counterparty. The Company nets resale and repurchase transactions with the same counterparty on the Consolidated Balance Sheets when it has a legally enforceable master netting agreement and the transactions are eligible for netting under ASC 210-20-45. Collateral accepted includes securities that are not recognized on the Consolidated Balance Sheets. Collateral pledged consists of securities that are not netted on the Consolidated Balance Sheets against the related collateralized liability. Collateral accepted or pledged in resale and repurchase agreements with other financial institutions may also be sold or re-pledged by the secured party, but is usually delivered to and held by the third party trustees. The collateral amounts received/posted are limited for presentation purposes to the related recognized asset/liability balance for each counterparty, and accordingly, do not include excess collateral received/pledged.

The following tables present resale and repurchase agreements included on the Consolidated Balance Sheets as of December 31, 2016 and 2015:

For each reporting period, the Company examines all individual securities that are in an unrealized loss position for OTTI.  For discussion of the factors and criteria the Company uses in analyzing securities for OTTI, see Note 1—Summary of Significant Accounting Policies— Available-for-SaleInvestment Securities to the Consolidated Financial Statements.

The unrealized losses were primarily attributed to the yield curve movement, in addition to widened liquidity spread and credit spread. The issuers of these securities have not, to the Company’s knowledge, established any cause for default on these securities. These securities have fluctuated in value since their purchase dates as market interest rates have fluctuated. The Company believes that the gross unrealized losses detailed in the previous tables are temporary and not due to reasons of credit quality. As a result, the Company expects to recover the entire amortized cost basis of these securities. Accordingly, no impairment loss has been recorded on the Company’s Consolidated Statements of Income for the years ended December 31, 2016, 2015 and 2014. At December 31, 2016, the Company had 170 available-for-sale investment securities in an unrealized loss position with no credit impairment, primarily comprised of 13 investment grade foreign bonds, 82 U.S. government agency and U.S. government sponsored enterprise mortgage-backed securities and 26 U.S. Treasury securities. As of December 31, 2015, the Company had 186 available-for-sale investment securities in an unrealized loss position with no credit impairment, primarily comprising of 85 U.S. government agency and U.S. government sponsored enterprise mortgage-backed securities, 39 U.S. Treasury securities and 12 corporate debt securities.

During the first quarter of 2016, the Company obtained a non-agency mortgage-backed investment security, through the securitization of multifamily real estate loans, which was classified as held-to-maturity and recorded at amortized cost. The Company has the intent and ability to hold the security to maturity.

Actual maturities of mortgage-backed securities can differ from contractual maturities because borrowers have the right to prepay obligations. In addition, such factors as prepayments and interest rates may affect the yields on the carrying values of mortgage-backed securities.

Available-for-sale investment securities with fair values of $767.4 million and $873.0 million as of December 31, 2016 and 2015, respectively, were pledged to secure public deposits, repurchase agreements, the Federal Reserve Bank’s discount window, or for other purposes required or permitted by law.

NOTE 6 — DERIVATIVES

The Company uses derivatives to manage exposure to market risk, including interest rate risk and foreign currency risk and to assist customers with their risk management objectives. The Company’s goal is to manage interest rate sensitivity and volatility so that movements in interest rates are not significant to earnings or capital. The Company also uses foreign exchange contracts to manage the foreign exchange risk associated with certain foreign currency-denominated assets and liabilities, as well as the Company’s investment in its China subsidiary. The Company recognizes all derivatives on the Consolidated Balance Sheets at fair value. While the Company designates certain derivatives as hedging instruments in a qualifying hedge accounting relationship, other derivatives consist of economic hedges. For additional information on the Company’s derivatives and hedging activities, see Note 1 — Summary of Significant Accounting Policies to the Consolidated Financial Statements.

Derivatives Designated as Hedging Instruments

Interest Rate Swaps on Certificates of Deposit — The Company is exposed to changes in the fair value of certain fixed rate certificates of deposit due to changes in the benchmark interest rate, London Interbank Offered Rate. Interest rate swaps designated as fair value hedges involve the receipt of fixed rate amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the agreements without the exchange of the underlying notional amount.

The total notional amounts of the interest rate swaps on certificates of deposit were $48.4 million and $112.9 million, as of December 31, 2016 and 2015, respectively. The fair value liabilities of the interest rate swaps were $6.0 million and $5.2 million as of December 31, 2016 and 2015, respectively. This decrease was primarily due to $63.7 million notional amounts of interest rate swaps on certificates of deposit that were called during the year ended December 31, 2016.

The following table presents the net gains (losses) recognized on the Consolidated Statements of Income related to derivatives designated as fair value hedges for the years ended December 31, 2016, 2015 and 2014:

($ in thousands)	Year Ended December 31,

Net amount recognized on fair value hedges (ineffective portion)	$	(637	)	$	262		$	101

For the years ended December 31, 2016 and 2015, the Company also recognized net reductions to interest expense of $3.0 million and $3.6 million, respectively, primarily related to net settlements of the derivatives.

Net Investment Hedges — Consistent with ASC 830-20, Foreign Currency Matters — Foreign Currency Transactions, ASC 815 allows hedging of the foreign currency risk of a net investment in a foreign operation. During the fourth quarter of 2015, the Company entered into foreign currency forward contracts to hedge its investment in East West Bank (China) Limited, a non-USD functional currency subsidiary in China. The hedging instruments designated as net investment hedges, involve hedging the risk of changes in the USD equivalent value of a designated monetary amount of the Company’s net investment in China, against the risk of adverse changes in the foreign currency exchange rate. During the year ended December 31, 2016, the Company designated new foreign currency forward contracts as new hedge relationships. The Company expects that the hedging instrument will be highly effective in offsetting the changes in the value of the hedged net investment attributable to the hedged risk. The Company recorded the changes in the carrying amount of its China subsidiary in the Foreign currency translation adjustment account within AOCI. Simultaneously, the effective portion of the hedge of this exposure was also recorded in the Foreign currency translation adjustment account and the ineffective portion, if any, was recorded in current earnings.

As of December 31, 2016, the total notional amount and fair value of the foreign currency forward contracts were $83.0 million and a $4.3 million asset, respectively. As of December 31, 2015, the total notional amount and fair value of the foreign currency forward contracts were $86.6 million and a $2.4 million asset, respectively. The following table presents the gains recorded in the Foreign currency translation adjustment account within AOCI related to the effective portion of the net investment hedges and the ineffectiveness recorded on the Consolidated Statements of Income for the years ended December 31, 2016, 2015 and 2014:

Derivatives Not Designated as Hedging Instruments

Interest Rate Swaps and Options — The Company enters into interest rate derivatives including interest rate swaps and options with its customers to allow them to hedge against the risk of rising interest rates on their variable rate loans. To economically hedge against the interest rate risks in the products offered to its customers, the Company enters into mirrored interest rate contracts with institutional counterparties.  As of December 31, 2016, the total notional amount of interest rate swaps and options, including mirrored transactions with institutional counterparties and the Company’s customers totaled $3.86 billion for derivatives that were in an asset valuation position and $3.81 billion for derivatives that were in a liability valuation position. As of December 31, 2015, the total notional amount of interest rate swaps and options, including mirrored transactions with institutional counterparties and the Company’s customers totaled $3.25 billion for derivatives that were in an asset valuation position and $3.25 billion for derivatives that were in a liability valuation position. The fair values of the interest rate swap and option contracts with institutional counterparties and the Company’s customers amounted to a $67.6 million asset and a $65.1 million liability as of December 31, 2016. The fair values of the interest rate swap and option contracts with institutional counterparties and the Company’s customers amounted to a $67.2 million asset and a $67.3 million liability as of December 31, 2015.

Foreign Exchange Contracts — The Company enters into foreign exchange contracts on a regular basis to economically hedge against foreign exchange rate fluctuations. A majority of these contracts have original maturities of approximately one year. As of December 31, 2016 and 2015, the total notional amounts of short-term foreign exchange contracts were $767.8 million and $653.0 million, respectively.  The fair values of the short-term foreign exchange contracts recorded were an $11.9 million asset and an $11.2 million liability as of December 31, 2016. The fair values of short-term foreign exchange contracts recorded were a $10.3 million asset and a $9.4 million liability as of December 31, 2015.

93

RPA — The Company has entered into RPAs, under which the Company assumed its pro-rata share of the credit exposure associated with the borrower’s performance related to interest rate derivative contracts. The Company may or may not be a party to the interest rate derivative contract and enters into such RPAs in instances where the Company is a party to the related loan participation agreement with the borrower. The Company will make/receive payments under the RPAs if the borrower defaults on its obligation to perform under the interest rate derivative contract. The Company manages its credit risk on the RPAs by monitoring the credit worthiness of the borrowers, which is based on the normal credit review process. The notional amounts of the RPAs reflect the Company’s pro-rata share of the derivative instrument. As of December 31, 2016, the notional amount and the fair value of RPAs purchased were approximately $48.3 million and a $3 thousand liability, respectively. As of December 31, 2016, the notional amount and the fair value of RPAs sold were approximately $23.1 million and a $3 thousand asset, respectively. As of December 31, 2015, the notional amount and the fair value of RPAs purchased were approximately $33.7 million and a $4 thousand liability, respectively. As of December 31, 2015, the notional amount of the RPA sold was approximately $9.3 million and the fair value of the derivative asset was insignificant. Assuming all underlying borrowers referenced in the interest rate derivative contracts defaulted as of December 31, 2016 and 2015, the exposures from the RPAs purchased would be $179 thousand and $257 thousand, respectively.  As of December 31, 2016 and 2015, the weighted average remaining maturities of the outstanding RPAs were 3.7 years and 3.2 years, respectively.

Foreign Exchange Options — During 2010, the Company entered into foreign exchange option contracts with major brokerage firms to economically hedge against foreign exchange fluctuations in certain certificates of deposit available to its customers. These certificates of deposit had a term of five years and paid interest based on the performance of the RMB relative to the USD. Under ASC 815, a certificate of deposit that pays interest based on changes in foreign exchange rates is a hybrid instrument with an embedded derivative that must be accounted for separately from the host contract (i.e., the certificate of deposit). In accordance with ASC 815, both the embedded derivative instruments and the freestanding foreign exchange option contracts are recorded at fair value. These instruments expired in the second quarter of 2015.

The following table presents the net gains (losses) recognized on the Company’s Consolidated Statements of Income related to derivatives not designated as hedging instruments for the years ended December 31, 2016, 2015 and 2014:

Total net gains (losses)		$	15,189	$	4,400		$	(5,637	)

Credit-Risk-Related Contingent Features— Certain over-the-counter derivative contracts of the Company contain early termination provisions that may require the Company to settle any outstanding balances upon the occurrence of a specified credit-risk-related event. These events, which are defined by the existing derivative contracts, primarily relate to a downgrade in the credit rating of East West Bank to below investment grade. In the event that East West Bank’s credit rating is downgraded to below investment grade, no additional collateral would be required to be posted, since the liabilities related to such contracts were fully collateralized as of December 31, 2016 and 2015.

Offsetting of Derivatives

The Company has entered into agreements with certain counterparty financial institutions, which include master netting agreements.  However, the Company has elected to account for all derivatives with counterparty institutions on a gross basis. The following tables present gross derivatives on the Consolidated Balance Sheets and the respective collateral received or pledged in the form of other financial instruments, which are generally marketable securities and/or cash. The collateral amounts in these tables are limited to the outstanding balances of the related asset or liability (after netting is applied); thus instances of overcollateralization are not shown:

NOTE 7 — LOANS RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES

The held-for-investment loan portfolio includes originated and purchased loans. Originated and purchased loans with no evidence of credit deterioration at their acquisition date are referred to collectively as non-PCI loans. PCI loans are loans acquired with evidence of credit deterioration since their origination and it is probable at the acquisition date that the Company would be unable to collect all contractually required payments. PCI loans are accounted for under ASC Subtopic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. The Company has elected to account for PCI loans on a pool level basis under ASC 310-30 at the time of acquisition.

The following table presents the composition of the Company’s non-PCI and PCI loans as of December 31, 2016 and 2015:

CRE loans include income producing real estate, construction and land loans where the interest rates may be fixed, variable or hybrid. Included in CRE loans are owner occupied CRE loans, and also non-owner occupied CRE loans where the borrowers rely on income from tenants to debt service the loan. Commercial business and trade finance in the C&I segment provide financing to businesses in a wide spectrum of industries.

Residential loans are comprised of single-family and multifamily loans. The Company offers first lien mortgage loans secured by one-to-four unit residential properties located in its primary lending areas. The Company offers a variety of first lien mortgage loan programs, including fixed rate conforming loans and adjustable rate mortgage (“ARM”) loans with initial fixed periods of one to five years, which adjust annually thereafter.

Consumer loans are comprised of home equity lines of credit (“HELOCs”), auto loans, and insurance premium financing loans. As of December 31, 2016 and 2015, the Company’s HELOCs are the largest component of the consumer loan portfolio, and are secured by one-to-four unit residential properties located in its primary lending areas. The HELOCs loan portfolio is largely comprised of loans originated through a reduced documentation loan program, where a substantial down payment is required, resulting in a low loan to value ratio, typically 60% or less. The Company is in a first lien position for many of these reduced documentation HELOCs. These loans have historically experienced low delinquency and default rates.

96

All loans originated are subject to the Company’s underwriting guidelines and loan origination standards. Management believes that the Company’s underwriting criteria and procedures adequately consider the unique risks which may come from these products. The Company conducts a variety of quality control procedures and periodic audits, including review of criteria for lending and legal requirements, to ensure it is in compliance with its origination standards.

As of December 31, 2016 and 2015, loans totaling $16.44 billion and $15.91 billion, respectively, were pledged to secure borrowings and to provide additional borrowing capacity from the FHLB and the Federal Reserve Bank.

Credit Quality Indicators

All loans are subject to the Company’s internal and external credit review and monitoring. Loans are risk rated based on an analysis of the current state of the borrower’s credit quality. The analysis of credit quality includes a review of all repayment sources, the borrower’s current payment performance/delinquency, current financial and liquidity status and all other relevant information.  For single-family residential loans, payment performance/delinquency is the driving indicator for the risk ratings.  Risk ratings are the overall credit quality indicator for the Company and the credit quality indicator utilized for estimating the appropriate allowance for loan losses. The Company utilizes a risk rating system, which can be classified within the following categories: Pass, Watch, Special Mention, Substandard, Doubtful and Loss. The risk ratings reflect the relative strength of the repayment sources.

Pass and Watch loans are generally considered to have sufficient sources of repayment in order to repay the loan in full in accordance with all terms and conditions. These borrowers may have some credit risks that require monitoring, but full repayments are expected. Special Mention loans are considered to have potential weaknesses that warrant closer attention by management. Special Mention is considered a transitory grade. If potential weaknesses are resolved, the loan is upgraded to a Pass or Watch grade. If negative trends in the borrower’s financial status or other information indicates that the repayment sources may become inadequate, the loan is downgraded to a Substandard grade. Substandard loans are considered to have well-defined weaknesses that jeopardize the full and timely repayment of the loan. Substandard loans have a distinct possibility of loss, if the deficiencies are not corrected. Additionally, when management has assessed a potential for loss but a distinct possibility of loss is not recognizable, the loan is still classified as Substandard. Doubtful loans have insufficient sources of repayment and a high probability of loss. Loss loans are considered to be uncollectible and of such little value that they are no longer considered bankable assets. These internal risk ratings are reviewed routinely and adjusted based on changes in the borrowers’ financial status and the loans’ collectability.

Nonaccrual and Past Due Loans

Non-PCI loans that are 90 or more days past due are generally placed on nonaccrual status. Additionally, non-PCI loans that are not 90 or more days past due but have identified deficiencies, such as when the full collection of principal or interest becomes uncertain, are also placed on nonaccrual status. The following tables present the aging analysis on non-PCI loans as of December 31, 2016 and 2015:

For information on the policy for recording payments received and resuming accrual of interest on non-PCI loans that are placed on nonaccrual status, see Note 1 — Summary of Significant Accounting Policies to the Consolidated Financial Statements.

PCI loans are excluded from the above aging analysis tables as the Company has elected to account for these loans on a pool level basis under ASC 310-30 at the time of acquisition. Please refer to the discussion on PCI loans within this note for additional details on interest income recognition. As of December 31, 2016 and 2015, PCI loans on nonaccrual status totaled $11.7 million and $37.7 million, respectively.

Loans in Process of Foreclosure

As of December 31, 2016 and 2015, the Company had $3.1 million and $17.4 million, respectively, of recorded investment in consumer mortgage loans secured by residential real estate properties, for which formal foreclosure proceedings were in process according to local requirements of the applicable jurisdictions, which were not included in OREO. Foreclosed residential real estate properties with a carrying amount of $401 thousand were included in total net OREO of $6.7 million as of December 31, 2016. In comparison, foreclosed residential real estate properties with a carrying amount of $912 thousand were included in total net OREO of $7.0 million as of December 31, 2015.

TDRs

Potential TDRs are individually evaluated and the type of restructuring is selected based on the loan type and the circumstances of the borrower’s financial difficulty in order to maximize the Company’s recovery. A TDR is a modification of the terms of a loan when the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower, it would not otherwise consider.

The following tables present the additions to non-PCI TDRs for the years ended December 31,2016, 2015 and 2014:

Subsequent to restructuring, a TDR that becomes delinquent, generally beyond 90 days, is considered to have defaulted. As TDRs are individually evaluated for impairment under the specific reserve methodology, subsequent defaults do not generally have a significant additional impact on the allowance for loan losses. The following table presents information for loans modified as TDRs within the previous 12 months that have subsequently defaulted during the years ended December 31,2016, 2015 and 2014, and were still in default at the respective years ended:

PCI Loans

At the date of acquisition, PCI loans are pooled and accounted for at fair value, which represents the discounted value of the expected cash flows of the loan portfolio. A pool is accounted for as a single asset with a single interest rate, cumulative loss rate and cash flow expectation. The cash flows expected over the life of the pools are estimated by an internal cash flow model that projects cash flows and calculates the carrying values of the pools, book yields, effective interest income and impairment, if any, based on pool level events. Assumptions as to cumulative loss rates, loss curves and prepayment speeds are utilized to calculate the expected cash flows. The amount of expected cash flows over the initial investment in the loan represents the “accretable yield,” which is recognized as interest income on a level yield basis over the life of the loan. Prepayments affect the estimated life of PCI loans, which may change the amount of interest income, and possibly principal, expected to be collected. The excess of total contractual cash flows over the cash flows expected to be received at origination is deemed to be the “nonaccretable difference.”

107

The following table presents the changes in accretable yield for PCI loans for the years ended December 31,2016, 2015 and 2014:

Ending balance	$	136,247		$	214,907		$	311,688

Loans Held-for-Sale

Loans held-for-sale are carried at the lower of cost or fair value. When a determination is made at the time of commitment to originate or purchase loans as held-for-investment, it is the Company’s intent to hold these loans to maturity or for the “foreseeable future,” subject to periodic reviews under the Company’s management evaluation processes, including asset/liability management. When the Company subsequently changes its intent to hold certain loans, the loans are transferred from the loans held-for-investment portfolio to the loans held-for-sale portfolio at the lower of cost or fair value.

Loans held-for-sale amounted to $23.1 million and $32.0 million as of December 31, 2016 and 2015, respectively, and were comprised primarily of consumer loans. Transfers of loans held-for-investment to loans held-for-sale were $814.2 million for the year ended December 31, 2016. These loan transfers were comprised of C&I, multifamily residential and CRE loans. In comparison, $1.69 billion and $837.4 million of loans held-for-investment were transferred to loans held-for-sale during the years ended December 31, 2015 and 2014, respectively. These loan transfers were comprised primarily of single-family residential and C&I loans for the year ended December 31, 2015, and consumer and C&I loans for the year ended December 31, 2014. The Company recorded $1.9 million, $5.1 million and $5.2 million, respectively, in write-downs to the allowance for loan losses related to loans transferred from loans held-for-investment to loans held-for-sale for the years ended December 31,2016, 2015 and 2014.

During the year ended December 31, 2016, the Company sold or securitized $571.3 million in originated loans, which were primarily comprised of mutifamily, C&I and CRE loans, resulting in net gains of $11.5 million. During the same period, the Company also recorded $1.1 million in net gains and $641 thousand in mortgage servicing rights, and retained $160.1 million of the senior tranche of the resulting securities from the securitization of $201.7 million of multifamily loans. In comparison, during the year ended December 31, 2015, the Company sold $1.04 billion in originated loans, which were comprised primarily of single-family residential and C&I loans, resulting in net gains of $26.1 million. During the year ended December 31, 2014, the Company sold $68.1 million in originated loans, which were comprised primarily of C&I loans, resulting in net gains of $7.2 million.

From time to time, the Company purchases and sells loans in the secondary market. During the year ended December 31, 2016, the Company purchased approximately $1.14 billion of loans, compared to $282.4 million and $865.2 million, respectively, during the years ended December 31,2015 and 2014. The increase in the loans purchased in 2016, compared to 2015, was primarily due to the purchase of single-family residential loans that were made to low-to-moderate income borrowers. Other loan purchases were largely made within the Company’s syndicated loan portfolio. Certain purchased loans were transferred from loans held-for-investment to loans held-for-sale and a write-down to allowance for loan losses was recorded, where appropriate. During the year ended December 31, 2016, the Company sold $259.1 million of loans in the secondary market at net gains of $188 thousand. In comparison, the Company sold $661.9 million and $1.02 billion, respectively, of loans in the secondary market during the years ended December 31, 2015 and 2014, resulting in net gains of $1.7 million and $31.9 million, respectively, during the same periods.

For the years ended December 31,2016 and 2015, the Company recorded valuation adjustments of $5.6 million and $3.0 million, respectively, in Net gains on sales of loans on the Consolidated Statements of Income to carry the loans held-for-sale portfolio at the lower of cost or fair value. No such valuation adjustment was recorded for the year ended December 31, 2014.

NOTE 8 — INVESTMENTS IN QUALIFIED AFFORDABLE HOUSING PARTNERSHIPS, TAX CREDIT AND OTHER INVESTMENTS, NET

The Community Reinvestment Act (“CRA”) encourages banks to meet the credit needs of their communities for housing and other purposes, particularly in neighborhoods with low or moderate income.  The Company invests in certain affordable housing limited partnerships that qualify for CRA credits. Such limited partnerships are formed to develop and operate apartment complexes designed as high-quality affordable housing for lower income tenants throughout the U.S. Each of the partnerships must meet the regulatory requirements for affordable housing for a minimum 15-year compliance period to fully utilize the tax credits.  In addition to affordable housing limited partnerships, the Company invests in new market tax credit projects that qualify for CRA credits and eligible projects that qualify for renewable energy and historic tax credits. Investments in renewable energy tax credits help promote the development of renewable energy sources, while the investments in historic tax credits promote the rehabilitation of historic buildings and economic revitalization of the surrounding areas.

Investments in Qualified Affordable Housing Partnerships, Net

The Company records its investments in qualified affordable housing partnerships, net, using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the amortization on the Consolidated Statements of Income as a component of income tax expense. The following table presents the balances of the Company’s investments in qualified affordable housing partnerships, net, and related unfunded commitments as of the periods indicated:

($ in thousands)	December 31,
	2016		2015

Amortization expense included in income tax expense	$	28,206	$	26,814	$	21,428

Investments in Tax Credit and Other Investments, Net

Investments in tax credit and other investments, net, were $173.3 million and $187.5 million as of December 31, 2016 and 2015, respectively. The Company is not the primary beneficiary in these partnerships and, therefore, is not required to consolidate its investments in tax credit and other investments on the Consolidated Financial Statements. Depending on the ownership percentage and the influence the Company has on the limited partnership, the Company applies either the equity method or cost method of accounting.

Total unfunded commitments for these investments were $117.0 million and $113.2 million as of December 31, 2016 and 2015, respectively, and were included in Accrued expenses and other liabilities on the Consolidated Balance Sheets. Amortization of tax credit and other investments were $83.4 million, $36.1 million and $44.1 million for the years ended December 31, 2016, 2015 and 2014, respectively.

NOTE 9—GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

Total goodwill of $469.4 million remained unchanged as of December 31, 2016 compared to December 31, 2015. Goodwill is tested for impairment on an annual basis as of December 31^st, or more frequently as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company’s three operating segments, Retail Banking, Commercial Banking, and Other, are equivalent to the Company’s reporting units. For complete discussion and disclosure, see Note 19 - Business Segments to the Consolidated Financial Statements.

Impairment Analysis

The Company performed its annual impairment analysis as of December 31, 2016 to determine whether and to what extent, if any, recorded goodwill was impaired. The Company used an income approach or a combined income and market approach to determine the fair value of the reporting units. Under the income approach, the Company provided a net income projection for the next three years plus a terminal growth rate that was used to calculate the discounted cash flows and the present value of the reporting units. Under the market approach, the fair value was calculated using the current fair values of comparable peer banks of similar size, geographic footprint and focus. The market capitalizations and multiples of these peer banks were used to calculate the market price of the Company and each reporting unit. The fair value was also subject to a control premium adjustment, which represents the cost savings that a purchaser of the reporting units could achieve by eliminating duplicative costs. Under the combined income and market approaches, the fair value from each approach was weighted based on management’s judgment to determine the fair value. As a result of this analysis, the Company determined that there was no goodwill impairment as of December 31, 2016 as the fair values of all reporting units exceeded the current carrying amounts of the goodwill. No assurance can be given that goodwill will not be written down in future periods.

Core Deposits Intangibles

Core deposit intangibles represent the intangible value of depositor relationships resulting from deposit liabilities assumed in various acquisitions. These intangibles are tested for impairment on an annual basis, or more frequently as events occur, or as current circumstances and conditions warrant. There were no impairment write-downs on core deposit intangibles for the years ended December 31, 2016, 2015 and 2014.

The following table presents the gross carrying value of intangible assets and accumulated amortization for the years ended December 31, 2016 and 2015:

NOTE 11 — FHLB ADVANCES AND LONG-TERM DEBT

FHLB Advances

FHLB advances totaled $321.6 million and $1.02 billion as of December 31, 2016 and 2015, respectively. The FHLB advances have floating interest rates that reset monthly or quarterly based on London Interbank Offered Rate (“LIBOR”). The weighted average interest rate was 1.13% and 0.51% as of December 31, 2016 and 2015, respectively. The interest rates ranged from 0.41% to 1.27% and 0.51% to 0.63% in 2016 and 2015, respectively. As of December 31, 2016, FHLB advances that will mature in the next five years are as follows: 2017 — $0.0 million; 2018 — $0.0 million; 2019 — $80.6 million; 2020 — $0.0 million; 2021 — $0.0 million and thereafter — $241.0 million.

The Company’s available borrowing capacity from FHLB advances totaled $5.58 billion and $4.45 billion as of December 31, 2016 and 2015, respectively. The Company’s available borrowing capacity from the FHLB is derived from its portfolio of loans that are pledged to the FHLB reduced by its outstanding FHLB advances. As of December 31, 2016 and 2015, all advances were secured by real estate loans.

(1) All the above debt instruments are subject to call options where early redemption requires appropriate notice.

The proceeds from these issuances represent liabilities of the Company to the Trusts and are reported on the Consolidated Balance Sheets as a component of long-term debt. Interest payments on these securities are made quarterly and are deductible for tax purposes. Beginning in 2016, trust preferred securities no longer qualify as Tier I capital and are limited to Tier II capital for regulatory purposes, based on the final rules issued by the Federal Reserve (“Basel III Capital Rules”). For further discussion, see Item 1. Business — Supervision and Regulation — Capital Requirements.

Term Loan — In 2013, the Company entered into a $100.0 millionthree-year term loan agreement. The terms of the agreement were modified in 2015 to extend the term loan maturity from July 1, 2016 to December 31, 2018, where principal repayments of $5.0 million are due quarterly. The term loan bears interest at the rate of the three-month LIBOR plus 150 basis points and the weighted average interest rate was 2.24% and 1.83% for the years ended December 31, 2016 and 2015, respectively. The outstanding balance of the term loan was $40.0 million and $60.0 million as of December 31, 2016 and 2015, respectively.

NOTE 12—INCOME TAXES

Income tax expense was $140.5 million for the year ended December 31, 2016, compared to $194.0 million and $101.1 million for years ended December 31,2015 and 2014, respectively. The effective tax rates were 24.6%, 33.5% and 22.6% for the years ended December 31,2016, 2015 and 2014, respectively. The lower effective tax rate during the year ended December 31, 2016 compared to the same period in 2015 was attributable to additional tax credits that were recognized from investments in qualified affordable housing, historic rehabilitation and renewable energy projects during the year ended December 31, 2016. The Company recognizes investment tax credits from these investments in the year the tax credits arise under the flow-through method of accounting. Included in income tax expense recognized during the years ended December 31,2016, 2015 and 2014 were $126.2 million, $67.6 million and $85.7 million, respectively, of tax credits generated from investments in qualified affordable housing partnerships and other tax credit investments.

The tax benefits of deductible temporary differences and tax carryforwards are recorded as an asset to the extent that management assesses the utilization of such temporary differences and carryforwards to be more likely than not. A valuation allowance is used, as needed, to reduce the deferred tax assets to the amount that is more likely than not to be realized. Evidence the Company considered includes the Company’s ability to generate future taxable income, implement tax-planning strategies, and utilize taxable income from prior carryback years (if such carryback is permitted under the applicable tax law), as well as future reversals of existing taxable temporary differences. The Company expects to have sufficient taxable income in future years to fully realize the deferred tax assets. Apart from this factor, the Company also performed an overall assessment by weighing all positive evidence against all negative evidence and concluded that it is more likely than not that all of the benefits of the deferred assets will be realized, with the exception of the deferred tax assets related to certain state NOL carryforwards. For states other than California, Georgia, Massachusetts and New York, since management believes that the state NOL carryforwards may not be fully utilized, a valuation allowance was recorded accordingly. The Company believes that adequate provisions have been made for all income tax uncertainties consistent with the standards of ASC 740-10. As of December 31, 2016 and 2015, the Company recorded net deferred tax assets of $129.7 million and $135.9 million, respectively, in Other assets on the Consolidated Balance Sheets.

The following table summarizes the activities related to the Company’s unrecognized tax benefits:

($ in thousands)	Year Ended December 31,
	2016			2015
Beginning Balance	$	7,125		$	5,020
Additions for tax positions of prior years	5,819			2,105
Settlements	(2,525		)	—
Ending Balance	$	10,419		$	7,125

As of December 31, 2016 and 2015, the total amount of unrecognized tax benefits that, if recognized, would favorably affect the effective income tax rate in the future was $6.8 million and $4.6 million, respectively. The Company recognizes interest and penalties, if applicable, related to the underpayment of income taxes as a component of Income Tax Expense on the Consolidated Statements of Income. The Company recorded a charge (reversal) of $6.2 million, ($460) thousand and $597 thousand of interest and penalties for the years ended December 31, 2016, 2015 and 2014, respectively. Total accrued interest and penalties included in Accrued expenses and other liabilities on the Consolidated Balance Sheets were $7.9 million and $1.8 million as of December 31, 2016 and 2015, respectively.

The foreign provision for income taxes is based on foreign pre-tax earnings of $4.5 million, $5.3 million and $12.6 million in 2016, 2015 and 2014, respectively. The Company’s consolidated financial statements provide for any related tax liability on undistributed earnings that the Company does not intend to be indefinitely reinvested outside the U.S. All of the Company’s undistributed international earnings intended to be indefinitely reinvested in operations outside the U.S. were generated by the Company’s subsidiary organized in China, which has a statutory tax rate of 25%. As of December 31, 2016, U.S. income taxes have not been provided on a cumulative total of $31.0 million of such earnings. The amount of unrecognized deferred tax liability related to these temporary differences is estimated to be $3.1 million.

Every year, subsequent to 2012, the Company has executed a Memorandum of Understanding (“MOU”) with the Internal Revenue Service (“IRS”) to voluntarily participate in the IRS Compliance Assurance Process (“CAP”). Under the CAP, the IRS audits the tax position of the Company, and identifies and resolves any tax issues that may arise throughout the tax year. The objective of the CAP is to resolve issues in a timely and contemporaneous manner and eliminate the need for a lengthy post-filing examination. Filed in September 2015, the 2014 tax return received a full acceptance of all tax matters from the IRS. The Company has executed a MOU with the IRS for the 2015 to 2017 tax years. For federal tax purposes, tax years from 2013 and beyond remain open. During the year ended December 31, 2016, the Company closed its audits for the tax years 2003 to 2008 with the California Franchise Tax Board and received a settlement of $4.7 million related to various refund claims under review. This settlement contributed to a $3.0 million income tax benefit during the year ended December 31, 2016. For California franchise tax purposes, tax years from 2009 and beyond remain open. The City of New York initiated an audit of the Company’s corporate income tax return for the 2012 to 2014 tax years in September 2016. The Company does not believe that the outcome of unresolved issues or claims in any tax jurisdiction is likely to be material to the Company’s financial position, cash flows or results of operations. The Company further believes that adequate provisions have been made for all income tax uncertainties. The Company does not anticipate that the total amount of unrecognized tax benefits will significantly change in the next twelve months.

NOTE 13—COMMITMENTS, CONTINGENCIES AND RELATED PARTY TRANSACTIONS

Credit Extensions — In the normal course of business, the Company has various outstanding commitments to extend credit that are not reflected on the Consolidated Financial Statements. While the Company does not anticipate losses as a result of these transactions, commitments to extend credit are included in determining the appropriate level of the allowance for unfunded commitments and outstanding commercial and standby letters of credit (“SBLCs”). The following table summarizes the Company’s credit-related commitments as of December 31, 2016 and 2015:

($ in thousands)	December 31,
	2016		2015
Loan commitments	$	5,077,869	$	3,370,271
Commercial letters of credit and SBLCs	$	1,525,613	$	1,293,547

115

Loan commitments are agreements to lend to a customer provided there is no violation of any condition established in the agreement. Commitments generally have fixed expiration dates or other termination clauses and may require maintenance of compensatory balances. Of the $5.08 billion unfunded loan commitments as of December 31, 2016, approximately $2.22 billion will expire within one year or less, $2.33 billion after one year through three years, $463.9 million after three years through five years, and $63.6 million thereafter. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future funding requirements.

Commercial letters of credit are issued to facilitate domestic and foreign trade transactions while SBLCs generally are contingent upon the failure of the customers to perform according to the terms of the underlying contract with the third party. As a result, the total contractual amounts do not necessarily represent future funding requirements. The Company’s historical experience is that SBLCs typically expire without being funded. Additionally, in many cases, the Company holds collateral in various forms against these SBLCs. As part of its risk management activities, the Company monitors the creditworthiness of customers in conjunction with its SBLC exposure. Customers are obligated to reimburse the Company for any payment made on their behalf. If a customer fails to pay, the Company would, as applicable, liquidate the collateral and/or offset accounts. Total letters of credit of $1.53 billion consisted of commercial letters of credit of $46.8 million and SBLCs of $1.48 billion as of December 31, 2016. Approximately $404.2 million of total letters of credit will expire within one year or less, $588.1 million after one year through three years, $325.1 million after three years through five years, and $208.2 million thereafter.

The Company uses the same credit underwriting criteria in extending loans, commitments, and conditional obligations to customers. Each customer’s creditworthiness is evaluated on a case-by-case basis. Collateral may be obtained based on management’s assessment of the customer’s credit. Collateral may include accounts receivable, inventory, property, plant and equipment, and income-producing commercial property.

Estimated exposure to loss from these commitments is included in the allowance for unfunded credit reserves and amounted to $15.7 million and $19.8 million as of December 31, 2016 and 2015, respectively. These amounts are included in Accrued expenses and other liabilities on the Consolidated Balance Sheets.

Guarantees — The Company has sold or securitized loans with recourse in the ordinary course of business. The recourse component in the loans sold or securitized with recourse is considered a guarantee. As the guarantor, the Company is obligated to make payments when the loans default. As of December 31, 2016 and December 31, 2015, the unpaid principal balance of total single-family and multifamily loans sold or securitized with recourse amounted to $150.5 million and $191.3 million, respectively. The allowance for unfunded credit reserves is included in Accrued expenses and other liabilities on the Consolidated Balance Sheets. The Company continues to experience minimal losses from the single-family and multifamily residential loan portfolios sold or securitized with recourse.

Lease Commitments — The Company conducts a portion of its operations utilizing leased premises and equipment under operating leases. Rental expense amounted to $24.1 million, $24.6 million and $26.2 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Future minimum rental payments under non-cancellable operating leases are estimated as follows:

Years Ending December 31,	Amount ($ in thousands)
2017	$	25,334
2018	22,083
2019	18,853
2020	14,699
2021	11,617
Thereafter	31,571
Total	$	124,157

Related Party Transactions — In the ordinary course of business, the Company may enter into transactions with various related parties. The Company’s related party transactions were not material for the years ended December 31, 2016 and 2015.

116

Litigation — The Company is a party to various legal actions arising in the normal course of business. In accordance with ASC 450, Contingencies, the Company accrues reserves for currently outstanding lawsuits, claims, and proceedings when a loss contingency is probable and can be reasonably estimated. The outcome of such legal actions is inherently difficult to predict and it is possible that one or more of the currently pending, or threatened legal or regulatory matters could have a material adverse effect on the Company’s liquidity, consolidated financial position, and/or results of operations. Based on the information currently available, advice of counsel and established reserves, the Company believes that the eventual outcome of pending legal matters will not individually or in the aggregate have a material adverse effect on the Company’s Consolidated Financial Statements. On September 8, 2014, a jury in the case titled “F&F, LLC and 618 Investment, Inc. v. East West Bank,” Superior Court of the State of California for the County of Los Angeles, Case No. BC462714, delivered a verdict in favor of plaintiff F&F, LLC. On November 2, 2016, the Company and plaintiff entered into a settlement agreement, fully resolving and discharging this matter, whereby the Company has agreed to pay $25.0 million to the plaintiff. The litigation accrual was $25.0 million and $35.4 million as of December 31, 2016 and 2015, respectively. The $25.0 million settlement was subsequently paid to the plaintiff in January 2017.

Other Commitments — The Company has commitments to invest in qualified affordable housing partnerships and other tax credit investments qualifying for community reinvestment tax credits or other types of tax credits. These commitments are payable on demand. As of December 31, 2016 and 2015, these commitments were $174.3 million and $174.7 million, respectively. These commitments are included in Accrued expenses and other liabilities on the Consolidated Balance Sheets.

NOTE 14—STOCK COMPENSATION PLANS

Pursuant to the Company’s 2016 Stock Incentive Plan, the Company may issue stock options, RSAs, RSUs, stock appreciation rights, stock purchase warrants, phantom stock and dividend equivalents to certain employees and non-employee directors of the Company and its subsidiaries. An aggregate of 14.0 million shares of common stock were authorized under the 2016 Stock Incentive Plan, and the total number available for grant was approximately 5.4 million as of December 31, 2016.

The following table summarizes the total share-based compensation expense and the related net tax benefit associated with its various employee share-based compensation plans for the years ended December 31, 2016, 2015 and 2014:

($ in thousands)	Year Ended December 31,

Net tax benefit recognized in equity for stock compensation plans	$	1,055	$	3,291	$	6,513

Stock Options — The Company issues stock options to certain employees, officers and directors. Stock options are issued at the current market price on the date of grant. No options have been granted since 2011. As of December 31, 2014, the Company had 42,116 stock options outstanding that were vested and exercisable at a weighted average exercise price of $20.75. The options had a four-year vesting period and contractual term of seven years. During 2015, all outstanding stock options have been fully exercised and there were no outstanding options as of December 31, 2015 and December 31, 2016.

The following table presents information related to stock options for the years ended December 31, 2016, 2015 and 2014:

RSAs and RSUs— RSAs and RSUs are granted under our long-term incentive plan at no cost to the recipient. RSAs vest ratably over three years, cliff vest after three years, or vest at a rate of 50% each at the fourth and fifth year of continued employment from the date of the grant. RSUs vest ratably over three years or cliff vest after three or five years of continued employment from the date of the grant. RSAs and RSUs entitle the recipient to receive cash dividends equivalent to any dividends paid on the underlying common stock during the period the RSAs and RSUs are outstanding. The RSAs have non-forfeitable rights to dividends or dividend equivalents and, as such, are considered participating securities as discussed in Note 1 — Summary of Significant Accounting Policiesto the Consolidated Financial Statements. During 2015, all RSAs have vested and there were no outstanding RSAs as of December 31, 2016. While a portion of the RSAs and RSUs are time-vesting awards, others vest subject to the attainment of specified performance goals. All RSAs and RSUs are subject to forfeiture until vested.

The following table presents a summary of the activity for the Company’s time-based and performance-based RSUs during the year ended December 31, 2016 based on the target amount of awards:

	2016
	Time-Based RSUs				Performance-Based RSUs
	Shares		Weighted Average Grant Date Fair Value		Shares		Weighted Average Grant Date Fair Value
Outstanding at beginning of year	933,312		$	36.83	389,358		$	34.21
Granted	529,385		31.86		159,407		29.18
Vested	(125,608	)	25.78		(138,019	)	25.25
Forfeited	(118,375	)	35.80		—		—
Outstanding at end of year	1,218,714		$	35.92	410,746		$	35.27

The weighted average fair values of the time-based awards granted during 2016, 2015 and 2014 were $31.86, $40.36 and $36.59, respectively. The weighted average fair value of the performance-based awards granted during the year ended December 31, 2016, 2015 and 2014 were $29.18, $41.15 and $36.85, respectively. The total fair value of time-based awards that vested during 2016, 2015 and 2014 was $4.2 million, $9.1 million and $21.6 million, respectively. The total fair value of performance-based awards that vested during 2016, 2015 and 2014 was $4.4 million, $5.8 million and $3.1 million, respectively.

Compensation costs for the time-based awards are based on the quoted market price of the Company’s stock at the grant date. Compensation costs for performance-based awards are based on the grant date fair value of the performance-based awards which considers both market and performance conditions. The associated compensation expense of the performance-based awards fluctuates with the estimated outcome of meeting the performance condition, where the total amount of compensation expense recognized on these awards will be finalized upon vesting of such awards.

Compensation costs of both time-based and performance-based awards are recognized on a straight-line basis from the grant date until the vesting date of each grant. As of December 31, 2016, total unrecognized compensation cost related to time-based and performance-based RSUs amounted to $21.9 million and $9.6 million, respectively. This cost is expected to be recognized over a weighted average period of 1.84 years and 1.71 years, respectively.

Stock Purchase Plan — The 1998 Employee Stock Purchase Plan (the “Purchase Plan”) provides eligible employees of the Company the right to purchase shares of its common stock at a discount. Employees could purchase shares at 90% of the fair market price subject to an annual purchase limitation of $22,500 per employee. As of December 31, 2016, the Purchase Plan qualifies as a non-compensatory plan under Section 423 of the Internal Revenue Code and, accordingly, no compensation expense has been recognized. 2,000,000 shares of the Company’s common stock have been made available for sale under the Purchase Plan. During 2016 and 2015, 67,198 shares totaling $2.1 million and 55,485 shares totaling $2.0 million, respectively, have been sold to employees under the Purchase Plan. As of December 31, 2016, there were 572,030 shares available under the Purchase Plan.

NOTE 15—EMPLOYEE BENEFIT PLANS

The Company sponsors a defined contribution plan, the East West Bank Employees 401(k) Savings Plan (the “Plan”), designed to provide retirement benefits financed by participants’ tax deferred contributions for the benefits of its employees.ARoth 401(k) investing option is also available to the participants, which is designed to be made on an after-tax basis. Under the terms of the Plan, eligible employees may elect to defer up to 80% of their compensation before taxes, up to the dollar limit imposed by the IRS for tax purposes. Participants can also designate a part or all of their contributions as Roth 401(k) contributions. Effective as of April 1, 2014, the Company matches 75% of the first 6% of the Plan participant’s deferred compensation. The Company’s contributions to the Plan are determined annually by the Board of Directors (the “Board”) in accordance with the Plan requirements. Plan participants become vested in the matching contributions received from the Plan sponsor at the rate of 20% per year for each full year of service after the first year such that the Plan participants become 100% vested after five years of credited service. For the Plan years ended December 31, 2016, 2015 and 2014, the Company expensed $8.4 million, $7.5 million and $5.9 million, respectively.

During 2002, the Company adopted a Supplemental Executive Retirement Plan (“SERP”). The SERP meets the definition of a pension plan per ASC 715-30, Compensation — Retirement Benefits — Defined Benefit Plans — Pension, pursuant to which the Company will pay supplemental pension benefits to certain executive officers designated by the Board upon retirement based upon the officers’ years of service and compensation. The SERP is an unfunded, non-qualified plan under which the participants have no rights beyond those of a general creditor of the Company, and there are no specific assets set aside by the Company in connection with the plan. As of December 31, 2016, there were no additional benefits to be accrued for under the SERP. As of December 31, 2016 and 2015, there were one and two executives remaining under the SERP. For the years ended December 31, 2016, 2015, and 2014, $624 thousand, $619 thousand and $583 thousand, respectively, of benefits were expensed and accrued for. The benefit obligation was $4.1 million and $6.1 million as of December 31, 2016 and 2015. The following table presents a summary of expected SERP payments to be paid for the next five years and thereafter as of December 31, 2016:

NOTE 18 — REGULATORY REQUIREMENTSAND MATTERS

Capital Adequacy — The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. The Bank is a member bank of the Federal Reserve System and the Federal Reserve Bank is the Bank’s primary regulator. In July 2013, the Federal Reserve Bank published Basel III Capital Rules establishing a new comprehensive capital framework for U.S. banking organizations based upon the 1988 capital accord (“Basel I”) of the Basel Committee on Banking Supervision. The Basel III Capital Rules apply to all depository institutions and top-tier bank holding companies with assets of $500.0 million or more, and accordingly are effective for the Company and the Bank on January 1, 2015 (subject to phase-in periods for certain of their components). The Basel III Capital Rules: (i) introduced a new capital measure called Common Equity Tier I Risk-based Capital (“CET1”) and a related regulatory capital ratio of CET1 to risk-weighted assets; (ii) specified that Tier I capital consists of CET1 and “Additional Tier I capital” instruments, which are instruments treated as Tier I instruments under the prior capital rules that meet certain revised requirements; (iii) mandated that most deductions or adjustments to regulatory capital measures be made to CET1 and not to the other components of capital; and (iv) expanded the scope of the deductions from and adjustments to capital, compared to existing regulations. The Basel III Capital Rules also prescribed a new standardized approach for risk weightings that expanded the risk weighting categories from the previous four Basel I-derived categories (0%, 20%, 50% and 100%) to a larger and more risk-sensitive number of categories.

The Federal Deposit Insurance Corporation Improvement Act of 1991 requires that the federal regulatory agencies adopt regulations defining capital tiers for banks: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. The Basel III Capital Rule requires that banking organizations maintain a minimum CET1 ratio of 4.5%, a Tier I capital ratio of 6.0%, and a total capital ratio of 8.0% to be considered adequately capitalized. Failure to meet minimum capital requirements can result in certain mandatory actions and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s Consolidated Financial Statements.

122

As of December 31, 2016 and 2015, the Company and the Bank were both categorized as well capitalized based on applicable U.S. regulatory capital ratio requirements in accordance with Basel III standardized approaches, as set forth in the table below. The Company believes that no changes in conditions or events have occurred since December 31, 2016, which would result in changes that would cause the Company or the Bank to fall below the well capitalized level. The following tables present the regulatory capital information of the Company and the Bank as of December 31, 2016 and 2015:

Reserve Requirement — The Bank is required to maintain a percentage of its deposits as reserves at the Federal Reserve Bank of San Francisco (the “FRB”). The daily average reserve requirement was approximately $503.8 million and $395.6 million as of December 31, 2016 and 2015, respectively.

123

Regulatory Matters — The Bank entered into a Written Agreement, dated November 9, 2015, with the FRB (the “Written Agreement”), to correct less than satisfactory Bank Secrecy Act (“BSA”) and Anti-Money Laundering (“AML”) programs detailed in a joint examination by the FRB and the California Department of Business Oversight (“DBO”). The Bank also entered into a related MOU with the DBO. The Written Agreement, among other things, requires the Bank to:

• within 60 days of the Written Agreement, submit a written plan to strengthen the Board’s oversight of the Bank’s compliance with the applicable laws, rules and regulations relating to AML, including compliance with the BSA, the rules and regulations issued thereunder by the U.S. Department of Treasury, and the AML requirements of Regulation H of the Board of Governors (collectively, “BSA/AML Requirements”);

• within 60 days of the Written Agreement, submit a written revised program for compliance with all applicable BSA/AML Requirements, which, at a minimum, will include, among other things, a system of internal controls to ensure compliance with all applicable BSA/AML Requirements and controls designed to ensure compliance with all applicable requirements relating to correspondent accounts for foreign financial institutions;

• within 60 days of the Written Agreement, submit a written revised program for conducting appropriate levels of customer due diligence, including policies, procedures, and controls to ensure that the Bank collects, analyzes, and retains complete and accurate customer information for all account holders, including customers of the Bank’s foreign operations;

• within 60 days of the Written Agreement, submit an enhanced written program to reasonably ensure the identification and timely, accurate and complete reporting by the Bank of all known or suspected violations of law or suspicious transactions to law enforcement and supervisory authorities as required by applicable suspicious activity reporting laws and regulations;

• within 60 days of the Written Agreement, submit a written plan to the FRB for the full installation, testing, and activation of an effective automated transaction monitoring system to reasonably ensure the identification and timely, accurate, and complete reporting by the Bank of all known or suspected violations of law or suspicious transactions to law enforcement and supervisory authorities;

• within 30 days following completion of the customer account remediation required by the Written Agreement, engage an independent consultant to conduct a review of, and prepare a report detailing findings relating to, account and transaction activity associated with any high risk customer accounts during a six-month period in 2014 to determine whether suspicious activity involving high risk customer accounts or transactions was properly identified and reported; and

• within 60 days of the Written Agreement, submit a plan to enhance the Bank’s compliance with Office of Foreign Assets Control (“OFAC”) Regulations, including enhanced OFAC screening procedures and an improved methodology for assessing OFAC risks.

The Company believes that the Bank is making progress in executing the compliance plans and programs required by the Written Agreement and MOU, although there can be no assurances that our plans and progress will be found to be satisfactory by our regulators. To date, the Bank has added significant resources to meet the monitoring and reporting obligations imposed by the Written Agreement and will continue to require significant management and third party consultant resources to comply with the Written Agreement and MOU, and to address any additional findings or recommendations by the regulators. These incremental administrative and third party costs, as well as the operational restrictions imposed by the Written Agreement, may adversely affect the Bank’s results of operations.

If additional compliance issues are identified or if the regulators determine that the Bank has not satisfactorily complied with the terms of the Written Agreement, the regulators could take further actions with respect to the Bank and, if such further actions were taken, such actions could have a material adverse effect on the Bank. The operating and other conditions of the Written Agreement could lead to an increased risk of being subject to additional regulatory actions by the DBO or FRB or other government agencies, as well as additional actions resulting from future regular annual safety and soundness and compliance examinations by the federal and state regulators that downgrade the regulatory ratings of the Bank.

NOTE 19—BUSINESS SEGMENTS

The Company utilizes an internal reporting system to measure the performance of various operating segments within the Bank and the Company. The Company has identified three operating segments for purposes of management reporting: (1) Retail Banking; (2) Commercial Banking; and (3) Other. These three business divisions meet the criteria of an operating segment: the segment engages in business activities from which it earns revenues and incurs expenses, its operating results are regularly reviewed by the Company’s chief operating decision-maker to render decisions about resources to be allocated to the segment and assess its performance and discrete financial information is available.

The Retail Banking segment focuses primarily on retail operations through the Bank’s branch network. The Commercial Banking segment, which includes CRE, primarily generates commercial loans through the commercial lending offices located in the Bank’s production offices. Furthermore, the Company’s Commercial Banking segment offers a wide variety of international finance and trade services and products. The remaining centralized functions, including treasury activities and eliminations of inter-segment amounts, have been aggregated and included in the “Other” segment, which provides broad administrative support to the two core segments.

The Company’s internal funds transfer pricing assumptions are intended to promote core deposit growth and to reflect the current risk profiles of various loan categories within the credit portfolio. Internal transfer pricing assumptions and methodologies are reviewed at least annually to ensure that the Company’s process is reflective of current market conditions. The internal transfer pricing process is formulated with the goal of incenting loan and deposit growth that is consistent with the Company’s overall growth objectives, as well as to provide a reasonable and consistent basis for the measurement of the Company’s business segments and product net interest margins.

The accounting policies of the segments are the same as those described in Note 1 — Summary of Significant Accounting Policiesto the Consolidated Financial Statements. Operating segment results are based on the Company’s internal management reporting process, which reflects assignments and allocations of certain operating and administrative costs and the provision for credit losses. Net interest income is based on the Company’s internal funds transfer pricing system which assigns a cost of funds or a credit for funds to assets or liabilities based on their type, maturity or repricing characteristics. Noninterest income and noninterest expense, including depreciation and amortization, directly attributable to a segment are assigned to that business segment. Indirect costs, including overhead expense, are allocated to the segments based on several factors, including, but not limited to, full-time equivalent employees, loan volume and deposit volume. The provision for credit losses is allocated based on actual charge-offs for the period as well as average loan balances for each segment during the period. The Company evaluates overall performance based on profit or loss from operations before income taxes excluding nonrecurring gains and losses.

Changes in the Company’s management structure or reporting methodologies may result in changes in the measurement of operating segment results. Results for prior periods are generally restated for comparability for changes in management structure or reporting methodologies unless it is not deemed practicable to do so.

NOTE 20—PARENT COMPANY CONDENSED FINANCIAL STATEMENTS

The principal sources of East West’s income (on a parent company-only basis) are dividends from the Bank. In addition to dividend restrictions set forth in statutes and regulations, the banking agencies have the authority to prohibit or to limit the Bank from paying dividends, if, in the banking regulator’s opinion, payment of a dividend would constitute an unsafe or unsound practice in light of the financial condition of the Bank. The Bank declared $100.0 million and $111.6 million of dividends to East West during 2016 and 2014, respectively. The Bank did not declare any dividends to East West during 2015. For information on the statutory and regulatory limitations on the ability of the Company to pay dividends to its stockholders and on the Bank to pay dividends to East West, see Item 1. Business — Supervision and Regulation — Dividends and Other Transfers of Funds. The financial information of East West as of December 31, 2016 and 2015 and for the years ended December 31, 2016, 2015 and 2014 is as follows:

ITEM 9A.  CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

As of December 31, 2016, pursuant to Rule 13a-15(b) of the Exchange Act, the Company conducted an evaluation, under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act). Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2016.

The Company’s disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company in the reports that the Company files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. The Company’s disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that the Company files under the Exchange Act is accumulated and communicated to the Company’s management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control over Financial Reporting

The Company’s management is responsible for establishing and maintaining effective internal control over financial reporting (as defined in Rules 13a-15(f) of the Exchange Act). The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external purposes in accordance with U.S. GAAP.

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 policies or procedures may deteriorate.

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2016. In making this assessment, management used the criteria set forth in Internal Control – Integrated Framework 2013 issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the Company’s assessment, the Company concluded its internal control over financial reporting was effective based on those criteria as of December 31, 2016.

Changes in Internal Control over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting during the year ended December 31, 2016, that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

Audit Report of the Company’s Registered Public Accounting Firm

KPMG LLP, the independent registered public accounting firm that audited the Company’s Consolidated Financial Statements, issued an audit report on the effectiveness of internal control over financial reporting as of December 31, 2016. The report is presented on the following page.

133

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

East West Bancorp, Inc.:

We have audited East West Bancorp, Inc. and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control — Integrated Framework 2013 issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s 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 Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s 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, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (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 company’s assets that could have a material effect on the financial statements.

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

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control — Integrated Framework 2013 issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Consolidated Balance Sheets of the Company as of December 31, 2016 and 2015, and the related Consolidated Statements of Income, Comprehensive Income, Changes in Stockholders’ Equity and Cash Flows for each of the years in the three-year period ended December 31, 2016, and our report dated February 27, 2017 expressed an unqualified opinion on those Consolidated Financial Statements.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NOTE 1—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

East West Bancorp, Inc. (referred to herein on an unconsolidated basis as “East West” and on a consolidated basis as the “Company”) is a registered bank holding company that offers a full range of banking services to individuals and businesses through its subsidiary bank, East West Bank and its subsidiaries (“East West Bank” or the “Bank”). The Bank is the Company’s principal asset. As of December 31, 2016, the Company operated over 130 locations worldwide, included in the United States (“U.S.”) markets of California, Georgia, Massachusetts, Nevada, New York, Texas and Washington. In Greater China, the Company’s presence includes five full-service branches in Hong Kong, two in Shanghai, including one in the China (Shanghai) Pilot Free Trade Zone, Shantou and Shenzhen, and five representative offices in Beijing, Chongqing, Guangzhou, Taipei and Xiamen.

SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation — The accounting and reporting policies of the Company conform with United States Generally Accepted Accounting Principles (“U.S. GAAP”) and general practices in the banking industry. To prepare the Consolidated Financial Statements in conformity with U.S. GAAP, management must make estimates based on conditions that affect the reported amounts of assets and liabilities as of the date of the Consolidated Financial Statements and income and expenses during the reporting period and the related disclosures. Actual results could differ from those estimates. Certain items on the Consolidated Financial Statements and notes for the prior years have been reclassified to conform to the 2016 presentation.

Principles of Consolidation — The Consolidated Financial Statements include the accounts of East West and its wholly owned subsidiaries, East West Bank and East West Insurance Services, Inc. Intercompany transactions and accounts have been eliminated in consolidation. East West also has six wholly-owned subsidiaries that are statutory business trusts (the “Trusts”), one of which was the result of the acquisition of MetroCorp during the three months ended March 31, 2014, as discussed in Note 2—Business Combination to the Consolidated Financial Statements. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, the Trusts are not included on the Consolidated Financial Statements.

Cash and Cash Equivalents — Cash and cash equivalents include cash on hand, cash items in transit, cash due from the Federal Reserve Bank and other financial institutions, and federal funds sold with original maturities up to three months.

Interest-bearing Deposits with Banks — Interest-bearing deposits with banks include cash placed with other banks with original maturities greater than three months and less than one year.

Resale Agreements and Repurchase Agreements — Resale agreements are recorded at the balances at which the securities were acquired. The market values of the underlying securities collateralizing the related receivable of the resale agreements, including accrued interest, are monitored. Additional collateral may be requested by the Company from the counterparty when deemed appropriate. Repurchase agreements are accounted for as collateralized financing transactions and recorded at the balances at which the securities were sold. The Company may have to provide additional collateral for the repurchase agreements, as necessary. Collateral accepted includes securities that are not recognized on the Consolidated Balance Sheets. Collateral pledged consists of securities that are not netted on the Consolidated Balance Sheets against the related collateralized liability. Collateral accepted or pledged in resale and repurchase agreements with other financial institutions may also be sold or re-pledged by the secured party but is usually delivered to and held by the third party trustees. The Company has elected to offset resale and repurchase transactions with the same counterparty on the Consolidated Balance Sheets when it has a legally enforceable master netting agreement and when the transactions are eligible for netting under ASC 210-10-45.

Available-for-SaleInvestment Securities — The Company holds debt securities and marketable equity securities in its investment portfolio. These securities are classified as available-for-sale investment securities and reported at fair value. Unrealized gains and losses, after applicable income taxes, are reported in other comprehensive income. Amortization of premiums and accretion of discounts on available-for-sale investment securities are recorded as yield adjustments on such securities using the effective interest method. The specific identification method is used for determining cost in computing realized gains and losses on available-for-sale investment securities sold.

For each reporting period, all securities that are in an unrealized loss position are analyzed as part of the Company’s ongoing assessment of other-than-temporary impairment (“OTTI”). In determining whether an impairment is other than temporary, the Company considers the severity and duration of the decline in fair value, the length of time expected for recovery, the financial condition of the issuer, changes in the securities’ ratings and other qualitative factors, as well as whether the Company either plans to sell the security or it is more-likely-than-not that it will be required to sell the security before recovery of the amortized cost. If the impairment of the available-for-sale debt security is credit-related, an OTTI loss is recorded on the Consolidated Statements of Income. Otherwise, the non-credit-related impairment loss is recorded in other comprehensive income. If the Company intends to sell an available-for-sale debt security or believes it will be more-likely-than-not required to sell a security, the Company records the full amount of the impairment loss as an OTTI loss. Available-for-sale marketable equity securities are carried at fair value with net unrealized gains and losses included in other comprehensive income on an after-tax basis. If there is an other-than-temporary decline in the fair value of any individual available-for-sale marketable equity security, the cost basis is reduced and the Company reclassifies the associated net unrealized loss out of other comprehensive income with a corresponding charge to the Consolidated Statements of Income.

Loans Held-for-Sale — Loans held-for-sale are carried at lower of cost or fair value. When a determination is made at the time of commitment to originate or purchase loans as held-for-investment, it is the Company’s intent to hold these loans to maturity or for the “foreseeable future,” subject to periodic review under the Company’s management evaluation processes, including asset/liability management. When the Company subsequently changes its intent to hold certain loans, the loans are transferred from the loans held-for-investment portfolio to the loans held-for-sale portfolio at lower of cost or fair value. Loan origination fees on loans held-for-sale, net of certain costs of processing and closing the loans, are deferred until the time of sale and are included in computing gains or losses from the sales of the related loans. If the loan or a portion of the loan cannot be sold, it is subsequently transferred back into the loans held-for-investment portfolio from the loans held-for-sale portfolio at lower of cost or fair value on the transfer date. A valuation allowance is established if the fair value of such loans is lower than their cost, with a corresponding charge to noninterest income.

Loans Held-for-Investment — Loans receivable that the Company has the intent and ability to hold for the foreseeable future or until maturity are stated at their outstanding principal, reduced by an allowance for loan losses and net of deferred loan fees or costs on originated loans and unamortized premiums or discounts on purchased loans. Nonrefundable fees and direct costs associated with the origination or purchase of loans are deferred and netted against outstanding loan balances. The deferred net loan fees and costs are recognized in interest income as an adjustment to yield over the loan term using the effective interest method or straight-line method. Discounts or premiums on purchased loans are accreted or amortized to interest income using the effective interest method or straight-line method over the remaining period to contractual maturity. Interest on loans is calculated using the simple-interest method on daily balances of the principal amounts outstanding. Generally, loans are placed on nonaccrual status when they become 90 days past due. Loans are considered past due when contractually required principal or interest payments have not been made on the due dates. Loans are also placed on nonaccrual status when management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that full collection of principal or interest becomes uncertain, regardless of the length of past due status. Once a loan is placed on nonaccrual status, interest accrual is discontinued and all unpaid accrued interest is reversed against interest income. Interest payments received on nonaccrual loans are reflected as a reduction of principal and not as interest income. A loan is returned to accrual status when the borrower has demonstrated a satisfactory payment trend subject to management’s assessment of the borrower’s ability to repay the loan.

Troubled Debt Restructurings — A loan is classified as a troubled debt restructuring (“TDR”) when the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower that the Company would not otherwise consider. The concessions may be granted in various forms, including a below-market change in the stated interest rate, a reduction in the loan balance or accrued interest, an extension of the maturity date with a stated interest rate lower than the current market rate or note splits referred to as A/B note restructurings. In A/B note restructurings, the original note is bifurcated into A and B notes. The A note represents the portion of the modified original loan which allows for acceptable loan-to-value and debt coverage on the collateral and is expected to be collected in full. The B note represents the portion of the original loan where there is a shortfall in value and is fully charged off. The A/B note balance after the restructuring is comprised of the A note balance only, as the B note would have been charged off. A notes are not disclosed as TDRs in subsequent years after the year of restructuring, if the restructuring agreement specifies an interest rate equal to or greater than the rate that the Company was willing to accept at the time of the restructuring for a new loan with comparable risk; the loan is not impaired based on the terms specified by the restructuring agreement; and has demonstrated a period of sustained performance under the modified terms.

TDRs may be designated as performing or nonperforming. A TDR may be designated as performing if the loan has demonstrated sustained performance under the modified terms. The period of sustained performance may include the periods prior to modification, if prior performance has met or exceeded the modified terms. A loan will remain on nonaccrual status until the borrower demonstrates a sustained period of performance. TDRs are included in the impaired loan quarterly valuation allowance process. Refer to Impaired Loans below for a complete discussion.

Impaired Loans — The Company’s loans are grouped into heterogeneous and homogeneous (mostly consumer loans) categories. Classified loans in the heterogeneous category are identified and evaluated for impairment on an individual basis. A loan is considered impaired when, based on current information and events, it is probable that the Company will not be able to collect all scheduled payments of principal or interest due in accordance with the original contractual terms of the loan agreement. Factors considered by management in determining and measuring loan impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of and the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as appropriate, at the loan’s observable market price or the fair value of the collateral, if the loan is collateral dependent, less costs to sell. When the value of an impaired loan is less than the recorded investment and the loan is classified as nonperforming and uncollectible, the deficiency is charged off against the allowance for loan losses. If the loan is a performing TDR, the deficiency is included in the specific reserves of the allowance for loan losses, as appropriate. Payments received on impaired loans on nonaccrual status are not recognized in interest income, but are applied as a reduction to the principal outstanding. The Company’s impaired loans include predominantly non-purchased credit impaired (“non-PCI”) loans held-for-investment on nonaccrual status and any non-PCI loans modified as a TDR, on either accrual or nonaccrual status.

Allowance for Credit Losses — The allowance for credit losses consists of the allowance for loan losses and the allowance for unfunded credit reserves. Unfunded credit reserves include reserves provided for unfunded lending commitments, unissued standby letters of credit and recourse obligations for loans sold. The allowance for loan losses is established as management’s estimate of probable losses inherent in the Company’s lending activities. The allowance for loan losses is increased by the provision for loan losses and decreased by net charge-offs when management believes the uncollectability of a loan is probable. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated monthly by management based on management’s periodic review of the collectability of the loans.

The allowance for loan losses on non-PCI loans consists of specific reserves and general reserves. The Company’s non-PCI loans fall into heterogeneous and homogeneous categories. Impaired loans are subject to specific reserves. Loans in the homogeneous category, as well as non-impaired loans in the heterogeneous category, are evaluated as part of the general reserves. General reserves are calculated by utilizing both quantitative and qualitative factors. There are different qualitative risks for the loans in each portfolio segment. Predominant risk characteristics of the residential and commercial real estate (“CRE”) segments are the collateral and geographic locations of the properties collateralizing the loans. Predominant risk characteristics of the commercial and industrial (“C&I”) segment are the global cash flows of the borrowers and guarantors, as well as the economic and market conditions. Consumer loans are largely comprised of home equity lines of credit (“HELOCs”) and the predominant risk characteristic is the real estate collateral securing the loans.

The Company also maintains an allowance for loan losses on purchased credit impaired (“PCI”) loans when there is deterioration in credit quality subsequent to acquisition. Based on the Company’s estimates of cash flows expected to be collected, the Company establishes an allowance for the PCI loans, with a charge to Provision for credit losses on the Consolidated Statements of Income. 

When determined uncollectible, it is the Company’s policy to promptly charge off the difference of the outstanding loan balance and the fair value of the collateral or the discounted value of expected cash flows. Recoveries are recorded when payment is received on loans that were previously charged off through the allowance for loan losses. Allocation of a portion of the allowance to one segment of the loan portfolio does not preclude its availability to absorb losses in other segments.

The allowance for unfunded credit reserves is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities, including an assessment of the probability of commitment usage, credit risk factors for loans outstanding, and the terms and expiration dates of the unfunded credit facilities. The allowance for loan losses is reported separately on the Consolidated Balance Sheets, whereas the allowance for unfunded credit reserves is included in Accrued expenses and other liabilities on the Consolidated Balance Sheets. The provision for credit losses is reported on the Consolidated Statements of Income.

PCI Loans — Acquired loans are recorded at fair value as of acquisition date in accordance with ASC 805, Business Combinations. A purchased loan is deemed to be credit impaired when there is evidence of credit deterioration since its origination and it is probable at the acquisition date that the Company would be unable to collect all contractually required payments and is accounted for under ASC 310-30, Receivables — Loans and Debt Securities Acquired with Deteriorated Credit Quality. Under ASC 310-30, loans are recorded at fair value at acquisition date, factoring in credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for loan losses is not carried over or recorded as of the acquisition date.

The amount of expected cash flows over the initial investment in the loan represents the “accretable yield,” which is recognized as interest income on a level yield basis over the life of the loan. The excess of total contractual cash flows over the cash flows expected to be received at origination is deemed the “nonaccretable difference.” In estimating the nonaccretable difference, the Company (a) calculates the contractual amount and timing of undiscounted principal and interest payments (the “undiscounted contractual cash flows”) and (b) estimates the amount and timing of undiscounted expected principal and interest payments (the “undiscounted expected cash flows”). The cash flows expected over the life of the pools are estimated by an internal cash flow model that projects cash flows and calculates the carrying values of the pools, book yields, effective interest income and impairment, if any, based on pool level events. Assumptions such as cumulative loss rates, loss curves and prepayment speeds are utilized to calculate the expected cash flows. The difference between the undiscounted contractual cash flows and the undiscounted expected cash flows is the nonaccretable difference. Subsequent to the acquisition date, any increases in expected cash flows over the expected cash flows at purchase date in excess of fair value that are significant and probable are adjusted through the accretable yield on a prospective basis. Any subsequent decreases in expected cash flows over the expected cash flows at purchase date that are probable are recognized by a charge to the provision for loan losses. Any disposals of loans, including sales of loans, payments in full or foreclosures, result in the removal of the loan from the ASC 310-30 portfolio at the carrying amount.

Investments in Qualified Affordable Housing Partnerships, Tax Credit and Other Investments, Net — The Company records the investments in qualified affordable housing partnerships, net, using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the amortization on the Consolidated Statements of Income as a component of Income tax expense. The Company records investments in tax credit and other investments, net, using either the equity method or cost method of accounting. The tax credits are recognized on the Consolidated Financial Statements to the extent they are utilized on the Company’s income tax returns. The investments are reviewed for impairment on an annual basis or on an interim basis, if an event occurs that would trigger potential impairment.

Goodwill and Other Intangible Assets — Goodwill represents the excess of the purchase price over the fair value of net assets acquired in various past acquisitions. Goodwill is not amortized and is reviewed for impairment on an annual basis or on an interim basis, if an event occurs or circumstances change that would reduce the fair value of a reporting unit below its carrying value. Core deposit intangibles, which represent the intangible value of depositor relationships resulting from deposit liabilities assumed in acquisitions, are amortized over the projected useful lives of the deposits, which is typically 7 to 15 years. Core deposit intangibles are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment on goodwill and core deposit intangibles is recognized by writing down the asset as a charge to noninterest expense to the extent that the carrying value exceeds the estimated fair value.

Premises and Equipment, net — The Company’s premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed based on the straight-line method over the estimated useful lives of the various classes of assets. The ranges of estimated useful lives for the principal classes of assets are as follows:

Buildings and building improvements	25 years
Furniture, fixtures and equipment	3 to 7 years
Leasehold improvements	Term of lease or useful life, whichever is shorter

The Company reviews its long-lived assets for impairment annually or when events or changes in circumstances indicate that the carrying amounts of these assets may not be recoverable. An asset is considered impaired when the fair value, which is the expected undiscounted cash flows over the remaining useful life, is less than the net book value. The excess of the net book value over its fair value is charged as impairment loss to noninterest expense.

Long-Term Debt — Long-term debt consists of junior subordinated debt and a term loan. The Trusts issued both fixed and variable rate capital securities, representing undivided preferred beneficial interests in the assets of the Trusts, to third party investors. The Company is the owner of all the beneficial interests represented by the common securities of the Trusts. The purpose of issuing the capital securities was to provide the Company with a cost-effective means of obtaining Tier I capital for regulatory reporting purposes. Since the beginning of 2016, pursuant to the Basel III Capital Rules under Dodd-Frank Wall Street Reform and Consumer Protection Act, trust preferred securities have been fully phased out of Tier I capital and are now qualified as Tier II capital.

Income Taxes — The Company files consolidated federal income tax returns, foreign tax returns, and various combined and separate company state tax returns. The calculation of the Company's income tax provision and related tax accruals requires the use of estimates and judgments.

Accrued income tax liabilities (assets) represent the estimated amounts due to (receivable from) the various taxing jurisdictions where the Company has established a business presence.

Deferred tax assets and liabilities are recognized for the expected future tax consequences of existing temporary differences between the financial reporting and tax reporting basis of assets and liabilities using enacted tax laws and rates and tax carryforwards. To the extent a deferred tax asset is no longer expected more likely than not to be realized, a valuation allowance is established. See Note 12— Income Taxes for discussion of management assessment of evidence considered by the Company in establishing a valuation allowance.

The Company established an allowance for potential taxes, interest and penalties related to uncertain tax positions. This contingent reserve is estimated based on facts and circumstances, including the interpretation of existing law, new judicial or regulatory guidance, and the status of tax audits.

Stock-Based Compensation — The Company issues stock-based awards to certain employees, officers and directors, and accounts for the related costs in accordance with the provisions of ASC 505, Equity, and ASC 718, Compensation — Stock Compensation. Stock-based compensation cost is measured at the grant date based on the fair value of the awards, and expensed over the employee’s requisite service period.

The Company grants nonqualified stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”), which include service conditions for vesting. Additionally, some of the Company’s RSAs and RSUs contain performance conditions required to be met in order for the awards to vest. The stock option awards vest between three to four years from the grant date. RSAs vest ratably over three years, cliff vest after three years, or vest at a rate of 50% each at the fourth and fifth year of continued employment from the date of the grant. RSUs vest ratably over three years or cliff vest after three or five years of continued employment from the date of the grant. Compensation expense is amortized on a straight-line basis over the requisite service period for the entire award, which is generally the maximum vesting period of the award.

The fair values of stock options are estimated using the Black-Scholes option pricing model on the grant date. For time-based RSAs and RSUs, the grant-date fair values are measured at the fair value of the Company’s common stock as if the RSAs or RSUs are vested and issued on the date of grant. For performance based RSAs and RSUs, the grant date fair value considers both performance and market conditions (where applicable). As stock-based compensation expense is estimated based on awards ultimately expected to vest, it is reduced by the expense related to awards expected to be forfeited. Forfeitures are estimated at the time of grant and are reviewed annually for reasonableness. If the estimated forfeitures are revised, a cumulative effect of changes in estimated forfeitures for current and prior periods is recognized in compensation expense in the period of change.

EPS — Basic EPS is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during each period, plus common share equivalents calculated for stock options, warrants and RSUs outstanding using the treasury stock method. The Company has issued RSAs, which are unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents. These RSAs are considered participating securities. Accordingly, the Company applied the two-class method in the computation of basic and diluted EPS in the periods when the RSAs were outstanding. RSUs do not contain nonforfeitable rights to dividends when granted.

Derivatives — As part of the asset and liability management strategy, the Company uses derivative financial instruments to mitigate exposure to interest rate and foreign currency risks.  Derivatives utilized by the Company include swaps, forwards and option contracts.  All derivative instruments are included in Other assets or Other liabilities on the Consolidated Balance Sheets at fair value. The related cash flows are recognized on the Cash flows from operating activities section on the Consolidated Statement of Cash Flows. The Company uses its accounting hedges based on the exposure being hedged as either fair value hedges or hedges of the net investments in certain foreign operations. Changes in fair value of derivatives designated as fair value hedges are reported in Interest expense on the Consolidated Statements of Income.  Changes in fair value of derivatives used as hedges of the net investments in foreign operations, to the extent effective, are recorded as a component of AOCI. The change in fair value attributable to the ineffective portion of the hedging instrument is recognized immediately in Noninterest income on the Consolidated Statements of Income. For all other derivatives, changes in fair value are recognized on the Consolidated Statements of Income.

All derivatives designated as fair value hedges and hedges of the net investments in certain foreign operations are linked to specific hedged items or to groups of specific assets and liabilities on the Consolidated Balance Sheets.  To qualify as an accounting hedge under the hedge accounting rules (versus an economic hedge where hedge accounting is not sought), a derivative must be highly effective in offsetting the risk designated as being hedged.  The Company formally documents its hedge relationships at inception, including identification of the hedging instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction at the time the derivative contract is executed. Quarterly after the inception, the Company assesses whether the derivatives used in hedging transactions are highly effective in offsetting changes in the fair value of the hedged items.  Retroactive effectiveness is also assessed, as well as the continued expectation that the hedge will remain effective prospectively. 

The Company discontinues hedge accounting prospectively when (i) a derivative is no longer highly effective in offsetting changes in the fair value; (ii) a derivative expires or is sold, terminated, or exercised, or (iii) the Company determines that designation of a derivative as a hedge is no longer appropriate.  If a fair value hedge is discontinued, the derivative will continue to be recorded on the Consolidated Balance Sheets at its fair value with changes in fair value included on the Consolidated Statements of Income. When the hedged net investment is either sold or substantially liquidated, the effective portion of the changes in the fair value of the derivatives are reclassified out of AOCI into Foreign exchange income on the Consolidated Statements of Income.

The Company also offers various interest rate and foreign currency derivative products to customers and enters into derivative transactions in due course. These transactions are not linked to specific Company’s assets or liabilities on the Consolidated Balance Sheets or to forecasted transactions in a hedge relationship and, therefore, do not qualify for hedge accounting. The contracts are marked-to-market at the end of each reporting period with changes in fair value recorded on the Consolidated Statements of Income.

Fair Value — Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and, in many cases, requires management to make a number of significant judgments. Based on the observable inputs used in the valuation techniques, the Company classifies its assets and liabilities measured and disclosed at fair value in accordance with a three-level hierarchy (e.g., Level 1, Level 2 and Level 3) established under ASC 820, Fair Value Measurements. The Company records certain financial instruments, such as available-for-sale investment securities, and derivative assets and liabilities, at fair value on a recurring basis. Certain financial statement line items such as impaired loans, loans held-for-sale and OREO are recorded at fair value on a nonrecurring basis. Nonrecurring fair value measurements generally involve assets that are periodically evaluated for impairment. For additional information about fair value, see Note 3 — Fair Value Measurement And Fair Value Of Financial Instruments to the Consolidated Financial Statements.

Foreign Currency Translation — The Company revalues assets, liabilities, revenue and expense denominated in non-U.S. Dollars (“USD”) functional currencies into USD reporting currencies using applicable exchange rates. Gains and losses relating to nonfunctional currency transactions, including non-U.S. operations where the functional currency is USD, are reported on the Consolidated Statements of Income.

During the quarter ended September 30, 2015, the Company’s foreign subsidiary in China — East West Bank (China) Limited, changed its functional currency from USD to Renminbi (“RMB”). The assets and liabilities of this subsidiary are translated, for consolidation purposes, from RMB to USD reporting currency at period-end rates and generally at average rates for results of operations. Gains and losses arising from the translations are recorded in the Foreign currency translation adjustment account within AOCI in stockholders’ equity, along with any related hedged effects.

NEW ACCOUNTING PRONOUNCEMENTS ADOPTED

In February 2015, the FASB issued Accounting Standards Update (“ASU”) 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis that changes the analysis a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The amended guidance: 1) modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities; 2) eliminates the presumption that a general partner should consolidate a limited partnership; 3) affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and 4) provides a scope exception from the consolidation guidance for reporting entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a7 of the Investment Company Act of 1940 for registered money market funds. The Company adopted this amended guidance in the first quarter of 2016 and the adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

In April 2015, the FASB issued ASU 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 simplifies the presentation of debt issuance costs related to a recognized debt liability to be presented on the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The Company adopted this guidance retrospectively in the first quarter of 2016. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

In April 2015, the FASB issued ASU 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. ASU 2015-05 amends ASC 350-40 and requires the Company to determine whether a cloud computing arrangement contains a software license. If the arrangement contains a software license, the Company should account for the fees related to the software license element consistent with how the acquisitions of other software licenses are accounted for under ASC 350-40. If the arrangement does not contain a software license, the Company should account for the arrangement as a service contract. The Company adopted this guidance prospectively to all arrangements entered into or materially modified in the first quarter of 2016. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

In October 2016, the FASB issued ASU 2016-17, Consolidation (Topic 810):Interests Held through Related Parties That Are under Common Control to amend ASU 2015-02’s consolidation requirements that apply to a single decision maker’s evaluation of interests held through related parties that are under common control when it is determining whether it is the primary beneficiary of a VIE. ASU 2016-17 requires that the single decision maker considers its indirect economic interests in a VIE held through related parties that are under common control on a proportionate basis, in a manner consistent with its consideration of its indirect economic interests held through related parties that are not under common control. Entities that have adopted ASU 2015-02 are required to apply ASU 2016-17 retrospectively to all relevant prior periods beginning with the fiscal year in which ASU 2015-02 was initially applied. The Company adopted ASU 2016-17 retrospectively in the fourth quarter of 2016. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The new guidance replaced existing revenue recognition guidance for contracts to provide goods or services to customers.  ASU 2014-09 clarifies the principles for recognizing revenue and replaces nearly all existing revenue recognition guidance in U.S. GAAP. Quantitative and qualitative disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers are also required. ASU 2014-09 as amended by ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, is effective for interim and annual periods beginning after December 15, 2017 and is applied on either a modified retrospective or full retrospective basis. Early adoption is permitted for interim and annual periods beginning after December 15, 2016. The Company’s revenue is mainly comprised of net interest income from financial assets and liabilities, which is explicitly excluded from the scope of the new guidance, and noninterest income. The Company continues to evaluate the impact of ASU 2014-09 on our noninterest income and on our presentation and disclosures. The Company’s implementation efforts include the identification of revenue within the scope of ASU 2014-09 and the review is on-going.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 requires equity investments, except those accounted for under the equity method of accounting or consolidated, to be measured at fair value with changes recognized in net income. If there is no readily determinable fair value, the guidance allows entities the ability to measure investments at cost less impairment, whereby impairment is based on a qualitative assessment. The guidance eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value of financial instruments measured at amortized cost and changes the presentation of financial assets and financial liabilities on the Consolidated Balance Sheets or in the footnotes. If an entity has elected the fair value option to measure liabilities, the new accounting guidance requires the portion of the change in the fair value of a liability resulting from credit risk to be presented in other comprehensive income. The Company has not elected to measure any of its liabilities at fair value. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is not permitted except for certain specific changes under the fair value option guidance. To adopt the amendments, the Company is required to make a cumulative-effect adjustment to the consolidated balance sheet as of the beginning of the fiscal year in which the guidance is effective. However, the amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the adoption date. The Company is currently evaluating the impact on its Consolidated Financial Statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is intended to increase transparency and comparability in the accounting for lease transactions. ASU 2016-02 requires lessees to recognize all leases longer than twelve months on the Consolidated Balance Sheets as lease assets and lease liabilities and quantitative and qualitative disclosures regarding key information about leasing arrangements. Lessor accounting is largely unchanged. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years with an option to early adopt. The Company is currently evaluating the potential impact on its Consolidated Financial Statements. The Company expects a gross-up of its Consolidated Balance Sheets as a result of recognizing lease liabilities and right of use assets. The Company does not expect a material impact to its recognition of operating lease expense on its Consolidated Statements of Income.

In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships, to clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument in an existing hedging relationship would not be considered a termination of the derivative instrument or a change in a critical term of the hedging relationship provided that all other hedge accounting criteria in ASC 815 continue to be met. This clarification applies to both cash flow and fair value hedging relationships. ASU 2016-05 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years with an option to early adopt. The Company has an option to adopt the amendments of this ASU either on a prospective basis or modified retrospective basis. The adoption of this guidance will not have a material impact on the Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments that requires an entity to use a four step decision model when assessing contingent call (put) options that can accelerate the payment of principal on debt instruments to determine whether they are clearly and closely related to their debt hosts. ASU 2016-06 will be effective for interim and annual reporting periods beginning after December 15, 2016 and must be implemented using a modified retrospective basis. Early adoption is permitted. The adoption of this guidance will not have a material impact on the Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-07, Investments—Equity Method and Joint Ventures (Topic 323):Simplifying the Transition to the Equity Method of Accounting, to eliminate the requirement for an investor to retroactively apply the equity method when its increase in ownership interest (or degree of influence) in an investee triggers equity method accounting. The amendments in ASU 2016-07 also require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in AOCI at the date the investment becomes qualified for use of the equity method. ASU 2016-07 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years and should be applied prospectively. Early adoption is not permitted. The adoption of this guidance will not have a material impact on the Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, to simplify several aspects of the accounting for share-based payment transactions, including the accounting for income taxes, forfeitures, statutory tax withholding requirements, as well as classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The Company has adopted ASU 2016-09 in the first quarter of 2017 and has begun recording the excess tax benefits and deficiencies within the income tax expense on a prospective basis. The Company does not expect the adoption of this guidance to have a material impact on its Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments to introduce a new approach based on expected losses to estimate credit losses on certain types of financial instruments, which modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new “expected credit loss” impairment model will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, available-for-sale and held-to-maturity (“HTM”) debt securities, net investments in leases and off-balance-sheet credit exposures. For available-for-sale debt securities with unrealized losses, ASU 2016-13 does not change the measurement method of credit losses, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models and methods for estimating the allowance for loans and lease losses and requires disclosure of the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination (i.e., by vintage year). ASU 2016-13 is effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. Earlier adoption is permitted as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. While the Company is still evaluating the impact on its Consolidated Financial Statements, the Company expects that ASU 2016-13 may result in an increase in the allowance for credit losses due to the following factors: 1) the allowance for credit losses will increase to provide for expected credit losses over the remaining expected life of the loan portfolio, and will consider expected future changes in macroeconomic conditions; 2) the nonaccretable difference on the PCI loans will be recognized as an allowance, offset by an increase in the carrying value of the PCI loans; and 3) an allowance may be established for estimated credit losses on available-for-sale and HTM debt securities. The amount of increase will be impacted by the portfolio composition and quality, as well as the economic conditions and forecasts as of the adoption date. The Company has began its implementation efforts by identifying key interpretive issues, and assessing its processes and identifying the system requirements against the new guidance to determine what modifications may be required.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, to provide guidance on the classification of certain cash receipts and payments on the consolidated statement of cash flows in order to reduce diversity in practice. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of this guidance to have a material impact on its Consolidated Financial Statements.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, whichrequires the Company to include in its cash and cash-equivalent balances in the statement of cash flows those amounts that are deemed to be restricted cash and restricted cash equivalents. In addition, the Company is required to explain the changes in the combined total of restricted and unrestricted balances in the statement of cash flows. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, where the guidance should be applied using a retrospective transition method to each period presented. Early adoption is permitted. The Company is currently evaluating the impact on its Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment to simplify the accounting for goodwill impairments. An entity will no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. ASU 2017-04 also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. ASU 2017-04 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years and should be applied prospectively. Early adoption is permitted for interim or annual goodwill impairment tests with measurement dates after January 1, 2017. The Company is currently evaluating the impact on its Consolidated Financial Statements.

BUSINESS COMBINATION

NOTE 2 — BUSINESS COMBINATION

On January 17, 2014, the Company completed the acquisition of MetroCorp, parent of MetroBank, N.A. and Metro United Bank. MetroCorp was headquartered in Houston, Texas and previously operated 19 branch locations within Texas and California under its two banks. The Company acquired MetroCorp to further expand its presence, primarily in Texas, within the markets of Houston and Dallas, and in California, within the San Diego market. The purchase consideration was satisfied with two-thirds in East West common stock and one-third in cash. The fair value of the consideration transferred in the acquisition of MetroCorp was $291.4 million, which consisted of 5,583,093 shares of East West common stock fair valued at $190.8 million at the date of acquisition and $89.4 million in cash, $2.4 million of additional cash to MetroCorp stock option holders and a MetroCorp warrant, fair valued at $8.8 million, assumed by the Company.

The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. At the acquisition date, the Company recorded total fair value of assets acquired and liabilities assumed of $1.70 billion and $1.41 billion, respectively. The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the January 17, 2014 acquisition date. Goodwill from the acquisition represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired and is not deductible for tax purposes. The Company recorded $121.0 million of goodwill on the acquisition date. During the three months ended December 31, 2014, the Company recorded additional tax and bank-owned life insurance adjustments of $10.3 million and $700 thousand, respectively, related to the MetroCorp acquisition, increasing goodwill to $132.0 million.

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENT AND FAIR VALUE OF FINANCIAL INSTRUMENTS

NOTE 3 —FAIR VALUE MEASUREMENT AND FAIR VALUE OF FINANCIAL INSTRUMENTS

In determining fair value, the Company uses various methods including market and income approaches. Based on these approaches, the Company utilizes certain assumptions that market participants would use in pricing the asset or liability. These inputs can be readily observable, market corroborated or generally unobservable. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy noted below is based on the quality and reliability of the information used to determine fair value. The fair value hierarchy gives the highest priority to quoted prices available in active markets and the lowest priority to data lacking transparency. The fair value of the Company’s assets and liabilities is classified and disclosed in one of the following three categories:

•	Level 1	—	Valuation is based on quoted prices for identical instruments traded in active markets.
•	Level 2	—	Valuation is based on quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable and can be corroborated by market data.
•	Level 3	—	Valuation is based on significant unobservable inputs for determining the fair value of assets or liabilities. These significant unobservable inputs reflect assumptions that market participants may use in pricing the assets or liabilities.

In determining the appropriate hierarchy levels, the Company performs an analysis of the assets and liabilities that are subject to fair value disclosure. The Company’s assets and liabilities are classified in their entirety based on the lowest level of input that is significant to their fair value measurements.

The following tables present financial assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2016 and 2015:

Transfers into or out of fair value hierarchy classifications are made if the significant inputs used in the financial models measuring the fair values of the assets and liabilities become unobservable or observable in the current marketplace. The Company’s policy, with respect to transfers between levels of the fair value hierarchy, is to recognize transfers into and out of each level as of the end of the reporting period. There were no transfers of assets and liabilities measured on a recurring basis in and out of Level 1, Level 2 or Level 3 for the years ended December 31, 2016 and 2014. During the year ended December 31, 2015, the Company transferred $1.1 million of pooled trust preferred securities measured on a recurring basis out of Level 3 into Level 2 due to increased market liquidity and price observability. There were no transfers of assets and liabilities measured on a recurring basis between Level 1 and Level 2 during the year ended December 31, 2015.

Assets measured at fair value on a nonrecurring basis include certain non-PCI loans that were impaired, OREO and loans held-for-sale.  These fair value adjustments result from impairments recognized during the period on certain non-PCI impaired loans, application of fair value less cost to sell on OREO and application of the lower of cost or fair value valuation on loans held-for-sale.

The following is a description of the valuation methodologies and significant assumptions used to measure financial assets and liabilities at fair value and to estimate fair value for certain financial instruments not recorded at fair value. The description also includes the level of the fair value hierarchy in which the assets or liabilities are classified.

Cash and Cash Equivalents — The carrying amount approximates fair value due to the short-term nature of these instruments. As such, the estimated fair value is classified as Level 1.

Interest-bearing deposits with banks — The fair value of interest-bearing deposits with banks generally approximates their book value due to their short maturities.  In addition, due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

Resale Agreements — The fair value of resale agreements is estimated by discounting the cash flows based on expected maturities or repricing dates utilizing estimated market discount rates.  In addition, due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

Held-to-Maturity Investment Security — The fair value of the held-to-maturity investment security is determined by the discount cash flow approach. The discount rate is derived from conditional prepayment rate, constant default rate, loss severity and discount margin. Due to the significant unobservable inputs, the held-to-maturity investment security is classified as Level 3.

Available-for-SaleInvestment Securities — When available, the Company uses quoted market prices to determine the fair value of available-for-sale investment securities; such items are classified as Level 1.  Level 1 available-for-sale investment securities mainly include U.S. Treasury securities.  The fair values of other available-for-sale investment securities are generally determined by independent external pricing service providers who have experience in valuing these securities or by the average quoted market prices obtained from independent external brokers. In obtaining such valuation information from third parties, the Company has reviewed the methodologies used to develop the resulting fair values.  The available-for-sale investment securities valued using such methods are classified as Level 2.

Loans Held-for-Sale — The Company’s loans held-for-sale are carried at the lower of cost or fair value. These loans are mainly comprised of student loans.  The fair value of loans held-for-sale is derived from current market prices and comparative current sales. As such, the Company records any fair value adjustments on a nonrecurring basis. Loans held-for-sale are classified as Level 2.

Non-PCI Impaired Loans — The fair value of non-PCI impaired loans is measured using the market comparables or discounted cash flow techniques. For CRE loans and C&I loans, the fair value is based on each loan’s observable market price or the fair value of the collateral less cost to sell, if the loan is collateral dependent. The fair value of collateral is generally based on third party appraisals (or internal evaluation if third party appraisal is not required by regulations) which utilize one or more valuation techniques (income, market and/or cost approaches). All third party appraisals and evaluations are reviewed and validated by independent appraisers or the Company’s appraisal department staffed by licensed appraisers and/or experienced real estate reviewers. The third party appraisals are ordered through the appraisal department (except for one-to-four unit residential appraisals which are typically ordered through an approved appraisal management company or an approved residential appraiser) at the inception, renewal or, for all real estate related loans, upon the occurrence of any event causing a downgrade to an adverse grade (i.e., “substandard” or “doubtful”). Updated appraisals and evaluations are generally obtained within the last 12 months. The Company increases the frequency of obtaining updated appraisals for adversely graded credits when declining market conditions exist. All appraisals include an “as is” market value without conditions as of the effective date of the appraisal. For certain impaired loans, the Company utilizes the discounted cash flow approach and applies a discount derived from historical data. The significant unobservable inputs used in the fair value measurement of non-PCI impaired loans are discount applied based on the liquidation cost of collateral and selling cost. On a quarterly basis, all nonperforming assets are reviewed to assess whether the current carrying value is supported by the collateral or cash flow and to ensure that the current carrying value is appropriate. Non-PCI impaired loans are classified as Level 3.

Loans Held-for-Investment, net — The fair value of loans held-for-investment other than Non-PCI impaired loans is determined based on a discounted cash flow approach considered for an exit price value. The discount rate is derived from the associated yield curve plus spreads that reflect the rates in the market for loans with similar financial characteristics. No adjustments have been made for changes in credit within any of the loan portfolios. It is management’s opinion that the allowance for loan losses pertaining to performing and nonperforming loans results in a fair value valuation of credit for such loans. Due to the unobservable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 3.

OREO — The Company’s OREO represents properties acquired through foreclosure or through full or partial satisfaction of loans held-for-investment, which are recorded at estimated fair value less the cost to sell at the time of foreclosure and at the lower of cost or estimated fair value less the cost to sell subsequent to acquisition. The fair values of OREO properties are based on third party appraisals, broker price opinions or accepted written offers. Please refer to the Non-PCI Impaired Loans section above for a detailed discussion on the Company’s policies and procedures related to appraisals and evaluations. On a monthly basis, the current fair market value of each OREO property is reviewed to ensure that the current carrying value is appropriate. The Company uses the market comparable valuation technique to measure the fair value of OREO properties. The significant unobservable input used is the selling cost. OREO properties are classified as Level 3.

Investment inFHLB Stock and Federal Reserve Bank Stock — The carrying amounts of the Company’s investments in FHLB Stock and Federal Reserve Bank Stock approximate fair value. The valuation of these investments is classified as Level 2. Ownership of these securities is restricted to member banks and the securities do not have a readily determinable fair value.  Purchases and sales of these securities are at par value.

Accrued Interest Receivable — The carrying amount approximates fair value due to the short-term nature of these instruments. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

Interest Rate Swaps and Options — The Company enters into interest rate swap and option contracts with institutional counterparties to hedge against interest rate swap and option products offered to bank customers. These products allow borrowers to lock in attractive intermediate and long-term interest rates by entering into an interest rate swap or option contract with the Company, resulting in the customer obtaining a synthetic fixed rate loan. The Company also enters into interest rate swap contracts with institutional counterparties to hedge against certificates of deposit issued. This product allows the Company to lock in attractive floating rate funding. The fair value of interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash payments (or receipts) and the discounted expected variable cash receipts (or payments).  The variable cash receipts (or payments) are based on the expectation of future interest rates (forward curves) derived from observed market interest rate curves.  The fair value of interest rate options is determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates fell below (rise above) the strike rate of the floors (caps).  The variable interest rates used in the calculation of projected receipts on the floor (cap) are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. In addition, to comply with the provisions of ASC 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements of its derivatives. The credit valuation adjustments associated with the Company’s derivatives utilize Level 3 inputs, model-derived credit spreads. As of December 31, 2016, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of these interest rate contracts’ positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivative portfolios. As a result, the Company classifies these derivative valuations in Level 2 of the fair value hierarchy due to the observable nature of the significant inputs utilized.

Foreign Exchange Contracts — The Company enters into short-term foreign exchange contracts to purchase/sell foreign currencies at set rates in the future.  These contracts economically hedge against foreign exchange rate fluctuations. The Company also enters into contracts with institutional counterparties to hedge against foreign exchange products offered to bank customers. These products allow customers to hedge the foreign exchange risk of their deposits and loans denominated in foreign currencies. The Company assumes minimal foreign exchange rate risk because the contracts with the customer and the institutional party mirror each other.  The fair value is determined at each reporting period based on changes in the foreign exchange rate. These are over-the-counter contracts where quoted market prices are not readily available.  Valuation is measured using conventional valuation methodologies with observable market data.  Valuation depends on the type of derivative and the nature of the underlying rate and contractual terms including period of maturity, price and index upon which the derivative’s value is based. Key inputs include foreign exchange rates (spot and/or forward rates), volatility of currencies, and the correlation of such inputs. The counterparties’ credit risks are considered nominal and resulted in no adjustments to the valuation of the foreign exchange contracts. Due to the observable nature of the inputs used in deriving the fair value of these contracts, the valuation of foreign contracts is classified as Level 2.

Customer Deposits — The fair value of deposits with no stated maturity, such as demand deposits, interest checking, savings and money market deposits, approximates the carrying amount as the amounts are payable on demand at the measurement date. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2. For time deposits, the fair value is based on the discounted value of contractual cash flows using current market rates for instruments with similar maturities. Due to the observable nature of the inputs used in deriving the estimated fair value, time deposits are classified as Level 2.

FHLB Advances — The fair value of FHLB advances is estimated based on the discounted value of contractual cash flows, using rates currently offered by the FHLB of San Francisco for advances with similar remaining maturities at each reporting date. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

Repurchase Agreements — The fair value of the repurchase agreements is calculated by discounting future cash flows based on expected maturities or repricing dates, utilizing estimated market discount rates and taking into consideration the call features of each instrument. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

Accrued Interest Payable — The carrying amount approximates fair value due to the short-term nature of these instruments. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

Long-Term Debt — The fair value of long-term debt is estimated by discounting the cash flows through maturity based on current market rates the Company would pay for new issuances. Due to the observable nature of the inputs used in deriving the estimated fair value, long-term debt is classified as Level 2.

Foreign currency forward contracts — The Company enters into foreign currency forward contracts to hedge its net investment in East West Bank (China) Limited, a non-USD functional currency subsidiary in China. The fair value of foreign currency forward contracts is valued by comparing the contracted foreign exchange rate to the current market exchange rate. Inputs include spot rates, forward rates, and the interest rate curve of the domestic and foreign currency. Interest rate forward curves are used to determine which forward rate pertains to a specific maturity. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2.

RPAs — The Company enters into RPAs, under which the Company assumes its pro-rata share of the credit exposure associated with the borrower’s performance related to interest rate derivative contracts. The fair value of RPAs is calculated by determining the total expected asset or liability exposure of the derivatives to the borrowers and applying the borrowers’ credit spread to that exposure. Total expected exposure incorporates both the current and potential future exposure of the derivatives, derived from using observable inputs, such as yield curves and volatilities. The credit spreads of the borrowers used in the calculation are estimated by the Company based on current market conditions, including consideration of current borrowing spreads for similar customers and transactions, review of existing collateralization or other credit enhancements, and changes in credit sector and entity-specific credit information. The Company has determined that the majority of the inputs used to value RPAs fall within Level 2 of the fair value hierarchy.

The fair value estimates presented herein are based on pertinent information available to management as of each reporting date. Although the Company is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date, and therefore, current estimates of fair value may differ significantly from the amounts presented herein.

SECURITIES PURCHASED UNDER RESALE AGREEMENTS AND SOLD UNDER REPURCHASE AGREEMENTS

NOTE 4 — SECURITIES PURCHASED UNDER RESALE AGREEMENTS AND SOLD UNDER REPURCHASE AGREEMENTS

Resale Agreements

Resale agreements are recorded at the balances at which the securities were acquired. The market values of the underlying securities collateralizing the related receivable of the resale agreements, including accrued interest, are monitored. Additional collateral may be requested by the Company from the counterparty when deemed appropriate. Gross resale agreements were $2.10 billion and $2.05 billion as of December 31, 2016 and 2015, respectively. The weighted average interest rates were 1.84% and 1.61% as of December 31, 2016 and 2015, respectively. As of December 31, 2016, total gross resale agreements that are maturing in the next five years are as follows: 2017 — $1.40 billion; 2018 — $50.0 million; 2019 — $0.0 million; 2020 — $100.0 million; 2021 — $0.0 million and thereafter — $550.0 million.

Repurchase Agreements

Long-term repurchase agreements are accounted for as collateralized financing transactions and recorded at the balances at which the securities were sold. The collateral for these agreements is primarily comprised of U.S. government agency and U.S. government sponsored enterprise mortgage-backed securities, U.S. Treasury securities, and U.S. government agency and U.S. government sponsored enterprise debt securities. The Company may have to provide additional collateral for the repurchase agreements, as necessary.

Gross repurchase agreements were $450.0 million as of both December 31, 2016 and 2015. The weighted average interest rates were 3.15% and 2.60% as of December 31, 2016 and 2015, respectively. The Company had no charges related to the extinguishment of repurchase agreements for the years ended December 31, 2016 and 2014. In comparison, the Company recorded $21.8 million of charges related to the extinguishment of $545.0 million of repurchase agreements for the year ended December 31, 2015. All of the $450.0 million in gross repurchase agreements as of December 31, 2016 mature after 2021.

Balance Sheet Offsetting

The Company’s resale and repurchase agreements are transacted under legally enforceable master repurchase agreements that provide the Company, in the event of default by the counterparty, the right to liquidate securities held and to offset receivables and payables with the same counterparty. The Company nets resale and repurchase transactions with the same counterparty on the Consolidated Balance Sheets when it has a legally enforceable master netting agreement and the transactions are eligible for netting under ASC 210-20-45. Collateral accepted includes securities that are not recognized on the Consolidated Balance Sheets. Collateral pledged consists of securities that are not netted on the Consolidated Balance Sheets against the related collateralized liability. Collateral accepted or pledged in resale and repurchase agreements with other financial institutions may also be sold or re-pledged by the secured party, but is usually delivered to and held by the third party trustees. The collateral amounts received/posted are limited for presentation purposes to the related recognized asset/liability balance for each counterparty, and accordingly, do not include excess collateral received/pledged.

The following tables present resale and repurchase agreements included on the Consolidated Balance Sheets as of December 31, 2016 and 2015:

For each reporting period, the Company examines all individual securities that are in an unrealized loss position for OTTI.  For discussion of the factors and criteria the Company uses in analyzing securities for OTTI, see Note 1—Summary of Significant Accounting Policies— Available-for-SaleInvestment Securities to the Consolidated Financial Statements.

The unrealized losses were primarily attributed to the yield curve movement, in addition to widened liquidity spread and credit spread. The issuers of these securities have not, to the Company’s knowledge, established any cause for default on these securities. These securities have fluctuated in value since their purchase dates as market interest rates have fluctuated. The Company believes that the gross unrealized losses detailed in the previous tables are temporary and not due to reasons of credit quality. As a result, the Company expects to recover the entire amortized cost basis of these securities. Accordingly, no impairment loss has been recorded on the Company’s Consolidated Statements of Income for the years ended December 31, 2016, 2015 and 2014. At December 31, 2016, the Company had 170 available-for-sale investment securities in an unrealized loss position with no credit impairment, primarily comprised of 13 investment grade foreign bonds, 82 U.S. government agency and U.S. government sponsored enterprise mortgage-backed securities and 26 U.S. Treasury securities. As of December 31, 2015, the Company had 186 available-for-sale investment securities in an unrealized loss position with no credit impairment, primarily comprising of 85 U.S. government agency and U.S. government sponsored enterprise mortgage-backed securities, 39 U.S. Treasury securities and 12 corporate debt securities.

During the first quarter of 2016, the Company obtained a non-agency mortgage-backed investment security, through the securitization of multifamily real estate loans, which was classified as held-to-maturity and recorded at amortized cost. The Company has the intent and ability to hold the security to maturity.

OTTI

The following table presents a rollforward of the amounts related to the OTTI credit losses recognized in earnings for the years ended December 31:

No OTTI credit losses were recognized for the years ended December 31, 2016, 2015 and 2014. For the year ended December 31,2015, the Company realized a gain of $21.7 million from the sale of non-investment grade corporate debt securities with previously recognized OTTI credit losses of $112.3 million. For the year ended December 31, 2014, the Company realized a gain of $802 thousand from the sale of non-investment grade corporate debt securities with previously recognized OTTI credit losses of $3.2 million.

($ in thousands)	Amortized Cost		Estimated Fair Value
Due after ten years	$	143,971	$	144,593

Actual maturities of mortgage-backed securities can differ from contractual maturities because borrowers have the right to prepay obligations. In addition, such factors as prepayments and interest rates may affect the yields on the carrying values of mortgage-backed securities.

Available-for-sale investment securities with fair values of $767.4 million and $873.0 million as of December 31, 2016 and 2015, respectively, were pledged to secure public deposits, repurchase agreements, the Federal Reserve Bank’s discount window, or for other purposes required or permitted by law.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVES

NOTE 6 — DERIVATIVES

The Company uses derivatives to manage exposure to market risk, including interest rate risk and foreign currency risk and to assist customers with their risk management objectives. The Company’s goal is to manage interest rate sensitivity and volatility so that movements in interest rates are not significant to earnings or capital. The Company also uses foreign exchange contracts to manage the foreign exchange risk associated with certain foreign currency-denominated assets and liabilities, as well as the Company’s investment in its China subsidiary. The Company recognizes all derivatives on the Consolidated Balance Sheets at fair value. While the Company designates certain derivatives as hedging instruments in a qualifying hedge accounting relationship, other derivatives consist of economic hedges. For additional information on the Company’s derivatives and hedging activities, see Note 1 — Summary of Significant Accounting Policies to the Consolidated Financial Statements.

The following table presents the total notional and fair values of the Company’s derivatives as of December 31, 2016 and 2015:

(1) Derivative assets and derivative liabilities are included in Other Assets and Accrued expenses and other liabilities, respectively, on the Consolidated Balance Sheets.

Derivatives Designated as Hedging Instruments

Interest Rate Swaps on Certificates of Deposit — The Company is exposed to changes in the fair value of certain fixed rate certificates of deposit due to changes in the benchmark interest rate, London Interbank Offered Rate. Interest rate swaps designated as fair value hedges involve the receipt of fixed rate amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the agreements without the exchange of the underlying notional amount.

The total notional amounts of the interest rate swaps on certificates of deposit were $48.4 million and $112.9 million, as of December 31, 2016 and 2015, respectively. The fair value liabilities of the interest rate swaps were $6.0 million and $5.2 million as of December 31, 2016 and 2015, respectively. This decrease was primarily due to $63.7 million notional amounts of interest rate swaps on certificates of deposit that were called during the year ended December 31, 2016.

The following table presents the net gains (losses) recognized on the Consolidated Statements of Income related to derivatives designated as fair value hedges for the years ended December 31, 2016, 2015 and 2014:

($ in thousands)	Year Ended December 31,
	2016			2015			2014
(Losses) gains recorded in interest expense:
Recognized on interest rate swaps	$	(794	)	$	3,452		$	6,885
Recognized on certificates of deposit	157			(3,190		)	(6,784		)
Net amount recognized on fair value hedges (ineffective portion)	$	(637	)	$	262		$	101

For the years ended December 31, 2016 and 2015, the Company also recognized net reductions to interest expense of $3.0 million and $3.6 million, respectively, primarily related to net settlements of the derivatives.

Net Investment Hedges — Consistent with ASC 830-20, Foreign Currency Matters — Foreign Currency Transactions, ASC 815 allows hedging of the foreign currency risk of a net investment in a foreign operation. During the fourth quarter of 2015, the Company entered into foreign currency forward contracts to hedge its investment in East West Bank (China) Limited, a non-USD functional currency subsidiary in China. The hedging instruments designated as net investment hedges, involve hedging the risk of changes in the USD equivalent value of a designated monetary amount of the Company’s net investment in China, against the risk of adverse changes in the foreign currency exchange rate. During the year ended December 31, 2016, the Company designated new foreign currency forward contracts as new hedge relationships. The Company expects that the hedging instrument will be highly effective in offsetting the changes in the value of the hedged net investment attributable to the hedged risk. The Company recorded the changes in the carrying amount of its China subsidiary in the Foreign currency translation adjustment account within AOCI. Simultaneously, the effective portion of the hedge of this exposure was also recorded in the Foreign currency translation adjustment account and the ineffective portion, if any, was recorded in current earnings.

As of December 31, 2016, the total notional amount and fair value of the foreign currency forward contracts were $83.0 million and a $4.3 million asset, respectively. As of December 31, 2015, the total notional amount and fair value of the foreign currency forward contracts were $86.6 million and a $2.4 million asset, respectively. The following table presents the gains recorded in the Foreign currency translation adjustment account within AOCI related to the effective portion of the net investment hedges and the ineffectiveness recorded on the Consolidated Statements of Income for the years ended December 31, 2016, 2015 and 2014:

Derivatives Not Designated as Hedging Instruments

Interest Rate Swaps and Options — The Company enters into interest rate derivatives including interest rate swaps and options with its customers to allow them to hedge against the risk of rising interest rates on their variable rate loans. To economically hedge against the interest rate risks in the products offered to its customers, the Company enters into mirrored interest rate contracts with institutional counterparties.  As of December 31, 2016, the total notional amount of interest rate swaps and options, including mirrored transactions with institutional counterparties and the Company’s customers totaled $3.86 billion for derivatives that were in an asset valuation position and $3.81 billion for derivatives that were in a liability valuation position. As of December 31, 2015, the total notional amount of interest rate swaps and options, including mirrored transactions with institutional counterparties and the Company’s customers totaled $3.25 billion for derivatives that were in an asset valuation position and $3.25 billion for derivatives that were in a liability valuation position. The fair values of the interest rate swap and option contracts with institutional counterparties and the Company’s customers amounted to a $67.6 million asset and a $65.1 million liability as of December 31, 2016. The fair values of the interest rate swap and option contracts with institutional counterparties and the Company’s customers amounted to a $67.2 million asset and a $67.3 million liability as of December 31, 2015.

Foreign Exchange Contracts — The Company enters into foreign exchange contracts on a regular basis to economically hedge against foreign exchange rate fluctuations. A majority of these contracts have original maturities of approximately one year. As of December 31, 2016 and 2015, the total notional amounts of short-term foreign exchange contracts were $767.8 million and $653.0 million, respectively.  The fair values of the short-term foreign exchange contracts recorded were an $11.9 million asset and an $11.2 million liability as of December 31, 2016. The fair values of short-term foreign exchange contracts recorded were a $10.3 million asset and a $9.4 million liability as of December 31, 2015.

RPA — The Company has entered into RPAs, under which the Company assumed its pro-rata share of the credit exposure associated with the borrower’s performance related to interest rate derivative contracts. The Company may or may not be a party to the interest rate derivative contract and enters into such RPAs in instances where the Company is a party to the related loan participation agreement with the borrower. The Company will make/receive payments under the RPAs if the borrower defaults on its obligation to perform under the interest rate derivative contract. The Company manages its credit risk on the RPAs by monitoring the credit worthiness of the borrowers, which is based on the normal credit review process. The notional amounts of the RPAs reflect the Company’s pro-rata share of the derivative instrument. As of December 31, 2016, the notional amount and the fair value of RPAs purchased were approximately $48.3 million and a $3 thousand liability, respectively. As of December 31, 2016, the notional amount and the fair value of RPAs sold were approximately $23.1 million and a $3 thousand asset, respectively. As of December 31, 2015, the notional amount and the fair value of RPAs purchased were approximately $33.7 million and a $4 thousand liability, respectively. As of December 31, 2015, the notional amount of the RPA sold was approximately $9.3 million and the fair value of the derivative asset was insignificant. Assuming all underlying borrowers referenced in the interest rate derivative contracts defaulted as of December 31, 2016 and 2015, the exposures from the RPAs purchased would be $179 thousand and $257 thousand, respectively.  As of December 31, 2016 and 2015, the weighted average remaining maturities of the outstanding RPAs were 3.7 years and 3.2 years, respectively.

Foreign Exchange Options — During 2010, the Company entered into foreign exchange option contracts with major brokerage firms to economically hedge against foreign exchange fluctuations in certain certificates of deposit available to its customers. These certificates of deposit had a term of five years and paid interest based on the performance of the RMB relative to the USD. Under ASC 815, a certificate of deposit that pays interest based on changes in foreign exchange rates is a hybrid instrument with an embedded derivative that must be accounted for separately from the host contract (i.e., the certificate of deposit). In accordance with ASC 815, both the embedded derivative instruments and the freestanding foreign exchange option contracts are recorded at fair value. These instruments expired in the second quarter of 2015.

The following table presents the net gains (losses) recognized on the Company’s Consolidated Statements of Income related to derivatives not designated as hedging instruments for the years ended December 31, 2016, 2015 and 2014:

($ in thousands)	Location in Consolidated Statements of Income	Year Ended December 31,

Total net gains (losses)		$	15,189	$	4,400		$	(5,637	)

Credit-Risk-Related Contingent Features— Certain over-the-counter derivative contracts of the Company contain early termination provisions that may require the Company to settle any outstanding balances upon the occurrence of a specified credit-risk-related event. These events, which are defined by the existing derivative contracts, primarily relate to a downgrade in the credit rating of East West Bank to below investment grade. In the event that East West Bank’s credit rating is downgraded to below investment grade, no additional collateral would be required to be posted, since the liabilities related to such contracts were fully collateralized as of December 31, 2016 and 2015.

Offsetting of Derivatives

The Company has entered into agreements with certain counterparty financial institutions, which include master netting agreements.  However, the Company has elected to account for all derivatives with counterparty institutions on a gross basis. The following tables present gross derivatives on the Consolidated Balance Sheets and the respective collateral received or pledged in the form of other financial instruments, which are generally marketable securities and/or cash. The collateral amounts in these tables are limited to the outstanding balances of the related asset or liability (after netting is applied); thus instances of overcollateralization are not shown:

LOANS RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES

NOTE 7 — LOANS RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES

The held-for-investment loan portfolio includes originated and purchased loans. Originated and purchased loans with no evidence of credit deterioration at their acquisition date are referred to collectively as non-PCI loans. PCI loans are loans acquired with evidence of credit deterioration since their origination and it is probable at the acquisition date that the Company would be unable to collect all contractually required payments. PCI loans are accounted for under ASC Subtopic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. The Company has elected to account for PCI loans on a pool level basis under ASC 310-30 at the time of acquisition.

The following table presents the composition of the Company’s non-PCI and PCI loans as of December 31, 2016 and 2015:

CRE loans include income producing real estate, construction and land loans where the interest rates may be fixed, variable or hybrid. Included in CRE loans are owner occupied CRE loans, and also non-owner occupied CRE loans where the borrowers rely on income from tenants to debt service the loan. Commercial business and trade finance in the C&I segment provide financing to businesses in a wide spectrum of industries.

Residential loans are comprised of single-family and multifamily loans. The Company offers first lien mortgage loans secured by one-to-four unit residential properties located in its primary lending areas. The Company offers a variety of first lien mortgage loan programs, including fixed rate conforming loans and adjustable rate mortgage (“ARM”) loans with initial fixed periods of one to five years, which adjust annually thereafter.

Consumer loans are comprised of home equity lines of credit (“HELOCs”), auto loans, and insurance premium financing loans. As of December 31, 2016 and 2015, the Company’s HELOCs are the largest component of the consumer loan portfolio, and are secured by one-to-four unit residential properties located in its primary lending areas. The HELOCs loan portfolio is largely comprised of loans originated through a reduced documentation loan program, where a substantial down payment is required, resulting in a low loan to value ratio, typically 60% or less. The Company is in a first lien position for many of these reduced documentation HELOCs. These loans have historically experienced low delinquency and default rates.

All loans originated are subject to the Company’s underwriting guidelines and loan origination standards. Management believes that the Company’s underwriting criteria and procedures adequately consider the unique risks which may come from these products. The Company conducts a variety of quality control procedures and periodic audits, including review of criteria for lending and legal requirements, to ensure it is in compliance with its origination standards.

As of December 31, 2016 and 2015, loans totaling $16.44 billion and $15.91 billion, respectively, were pledged to secure borrowings and to provide additional borrowing capacity from the FHLB and the Federal Reserve Bank.

Credit Quality Indicators

All loans are subject to the Company’s internal and external credit review and monitoring. Loans are risk rated based on an analysis of the current state of the borrower’s credit quality. The analysis of credit quality includes a review of all repayment sources, the borrower’s current payment performance/delinquency, current financial and liquidity status and all other relevant information.  For single-family residential loans, payment performance/delinquency is the driving indicator for the risk ratings.  Risk ratings are the overall credit quality indicator for the Company and the credit quality indicator utilized for estimating the appropriate allowance for loan losses. The Company utilizes a risk rating system, which can be classified within the following categories: Pass, Watch, Special Mention, Substandard, Doubtful and Loss. The risk ratings reflect the relative strength of the repayment sources.

Pass and Watch loans are generally considered to have sufficient sources of repayment in order to repay the loan in full in accordance with all terms and conditions. These borrowers may have some credit risks that require monitoring, but full repayments are expected. Special Mention loans are considered to have potential weaknesses that warrant closer attention by management. Special Mention is considered a transitory grade. If potential weaknesses are resolved, the loan is upgraded to a Pass or Watch grade. If negative trends in the borrower’s financial status or other information indicates that the repayment sources may become inadequate, the loan is downgraded to a Substandard grade. Substandard loans are considered to have well-defined weaknesses that jeopardize the full and timely repayment of the loan. Substandard loans have a distinct possibility of loss, if the deficiencies are not corrected. Additionally, when management has assessed a potential for loss but a distinct possibility of loss is not recognizable, the loan is still classified as Substandard. Doubtful loans have insufficient sources of repayment and a high probability of loss. Loss loans are considered to be uncollectible and of such little value that they are no longer considered bankable assets. These internal risk ratings are reviewed routinely and adjusted based on changes in the borrowers’ financial status and the loans’ collectability.

Nonaccrual and Past Due Loans

Non-PCI loans that are 90 or more days past due are generally placed on nonaccrual status. Additionally, non-PCI loans that are not 90 or more days past due but have identified deficiencies, such as when the full collection of principal or interest becomes uncertain, are also placed on nonaccrual status.

For information on the policy for recording payments received and resuming accrual of interest on non-PCI loans that are placed on nonaccrual status, see Note 1 — Summary of Significant Accounting Policies to the Consolidated Financial Statements.

PCI loans are excluded from the above aging analysis tables as the Company has elected to account for these loans on a pool level basis under ASC 310-30 at the time of acquisition. Please refer to the discussion on PCI loans within this note for additional details on interest income recognition. As of December 31, 2016 and 2015, PCI loans on nonaccrual status totaled $11.7 million and $37.7 million, respectively.

Loans in Process of Foreclosure

As of December 31, 2016 and 2015, the Company had $3.1 million and $17.4 million, respectively, of recorded investment in consumer mortgage loans secured by residential real estate properties, for which formal foreclosure proceedings were in process according to local requirements of the applicable jurisdictions, which were not included in OREO. Foreclosed residential real estate properties with a carrying amount of $401 thousand were included in total net OREO of $6.7 million as of December 31, 2016. In comparison, foreclosed residential real estate properties with a carrying amount of $912 thousand were included in total net OREO of $7.0 million as of December 31, 2015.

TDRs

Potential TDRs are individually evaluated and the type of restructuring is selected based on the loan type and the circumstances of the borrower’s financial difficulty in order to maximize the Company’s recovery. A TDR is a modification of the terms of a loan when the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower, it would not otherwise consider.

The following tables present the additions to non-PCI TDRs for the years ended December 31,2016, 2015 and 2014:

Subsequent to restructuring, a TDR that becomes delinquent, generally beyond 90 days, is considered to have defaulted. As TDRs are individually evaluated for impairment under the specific reserve methodology, subsequent defaults do not generally have a significant additional impact on the allowance for loan losses. The following table presents information for loans modified as TDRs within the previous 12 months that have subsequently defaulted during the years ended December 31,2016, 2015 and 2014, and were still in default at the respective years ended:

PCI Loans

At the date of acquisition, PCI loans are pooled and accounted for at fair value, which represents the discounted value of the expected cash flows of the loan portfolio. A pool is accounted for as a single asset with a single interest rate, cumulative loss rate and cash flow expectation. The cash flows expected over the life of the pools are estimated by an internal cash flow model that projects cash flows and calculates the carrying values of the pools, book yields, effective interest income and impairment, if any, based on pool level events. Assumptions as to cumulative loss rates, loss curves and prepayment speeds are utilized to calculate the expected cash flows. The amount of expected cash flows over the initial investment in the loan represents the “accretable yield,” which is recognized as interest income on a level yield basis over the life of the loan. Prepayments affect the estimated life of PCI loans, which may change the amount of interest income, and possibly principal, expected to be collected. The excess of total contractual cash flows over the cash flows expected to be received at origination is deemed to be the “nonaccretable difference.”

The following table presents the changes in accretable yield for PCI loans for the years ended December 31,2016, 2015 and 2014:

Ending balance	$	136,247		$	214,907		$	311,688

Loans Held-for-Sale

Loans held-for-sale are carried at the lower of cost or fair value. When a determination is made at the time of commitment to originate or purchase loans as held-for-investment, it is the Company’s intent to hold these loans to maturity or for the “foreseeable future,” subject to periodic reviews under the Company’s management evaluation processes, including asset/liability management. When the Company subsequently changes its intent to hold certain loans, the loans are transferred from the loans held-for-investment portfolio to the loans held-for-sale portfolio at the lower of cost or fair value.

Loans held-for-sale amounted to $23.1 million and $32.0 million as of December 31, 2016 and 2015, respectively, and were comprised primarily of consumer loans. Transfers of loans held-for-investment to loans held-for-sale were $814.2 million for the year ended December 31, 2016. These loan transfers were comprised of C&I, multifamily residential and CRE loans. In comparison, $1.69 billion and $837.4 million of loans held-for-investment were transferred to loans held-for-sale during the years ended December 31, 2015 and 2014, respectively. These loan transfers were comprised primarily of single-family residential and C&I loans for the year ended December 31, 2015, and consumer and C&I loans for the year ended December 31, 2014. The Company recorded $1.9 million, $5.1 million and $5.2 million, respectively, in write-downs to the allowance for loan losses related to loans transferred from loans held-for-investment to loans held-for-sale for the years ended December 31,2016, 2015 and 2014.

During the year ended December 31, 2016, the Company sold or securitized $571.3 million in originated loans, which were primarily comprised of mutifamily, C&I and CRE loans, resulting in net gains of $11.5 million. During the same period, the Company also recorded $1.1 million in net gains and $641 thousand in mortgage servicing rights, and retained $160.1 million of the senior tranche of the resulting securities from the securitization of $201.7 million of multifamily loans. In comparison, during the year ended December 31, 2015, the Company sold $1.04 billion in originated loans, which were comprised primarily of single-family residential and C&I loans, resulting in net gains of $26.1 million. During the year ended December 31, 2014, the Company sold $68.1 million in originated loans, which were comprised primarily of C&I loans, resulting in net gains of $7.2 million.

From time to time, the Company purchases and sells loans in the secondary market. During the year ended December 31, 2016, the Company purchased approximately $1.14 billion of loans, compared to $282.4 million and $865.2 million, respectively, during the years ended December 31,2015 and 2014. The increase in the loans purchased in 2016, compared to 2015, was primarily due to the purchase of single-family residential loans that were made to low-to-moderate income borrowers. Other loan purchases were largely made within the Company’s syndicated loan portfolio. Certain purchased loans were transferred from loans held-for-investment to loans held-for-sale and a write-down to allowance for loan losses was recorded, where appropriate. During the year ended December 31, 2016, the Company sold $259.1 million of loans in the secondary market at net gains of $188 thousand. In comparison, the Company sold $661.9 million and $1.02 billion, respectively, of loans in the secondary market during the years ended December 31, 2015 and 2014, resulting in net gains of $1.7 million and $31.9 million, respectively, during the same periods.

For the years ended December 31,2016 and 2015, the Company recorded valuation adjustments of $5.6 million and $3.0 million, respectively, in Net gains on sales of loans on the Consolidated Statements of Income to carry the loans held-for-sale portfolio at the lower of cost or fair value. No such valuation adjustment was recorded for the year ended December 31, 2014.

NOTE 8 — INVESTMENTS IN QUALIFIED AFFORDABLE HOUSING PARTNERSHIPS, TAX CREDIT AND OTHER INVESTMENTS, NET

The Community Reinvestment Act (“CRA”) encourages banks to meet the credit needs of their communities for housing and other purposes, particularly in neighborhoods with low or moderate income.  The Company invests in certain affordable housing limited partnerships that qualify for CRA credits. Such limited partnerships are formed to develop and operate apartment complexes designed as high-quality affordable housing for lower income tenants throughout the U.S. Each of the partnerships must meet the regulatory requirements for affordable housing for a minimum 15-year compliance period to fully utilize the tax credits.  In addition to affordable housing limited partnerships, the Company invests in new market tax credit projects that qualify for CRA credits and eligible projects that qualify for renewable energy and historic tax credits. Investments in renewable energy tax credits help promote the development of renewable energy sources, while the investments in historic tax credits promote the rehabilitation of historic buildings and economic revitalization of the surrounding areas.

Investments in Qualified Affordable Housing Partnerships, Net

The Company records its investments in qualified affordable housing partnerships, net, using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the amortization on the Consolidated Statements of Income as a component of income tax expense. The following table presents the balances of the Company’s investments in qualified affordable housing partnerships, net, and related unfunded commitments as of the periods indicated:

Investments in Tax Credit and Other Investments, Net

Investments in tax credit and other investments, net, were $173.3 million and $187.5 million as of December 31, 2016 and 2015, respectively. The Company is not the primary beneficiary in these partnerships and, therefore, is not required to consolidate its investments in tax credit and other investments on the Consolidated Financial Statements. Depending on the ownership percentage and the influence the Company has on the limited partnership, the Company applies either the equity method or cost method of accounting.

Total unfunded commitments for these investments were $117.0 million and $113.2 million as of December 31, 2016 and 2015, respectively, and were included in Accrued expenses and other liabilities on the Consolidated Balance Sheets. Amortization of tax credit and other investments were $83.4 million, $36.1 million and $44.1 million for the years ended December 31, 2016, 2015 and 2014, respectively.

The Company’s unfunded commitments related to investments in qualified affordable housing partnerships, tax credit and other investments, net, are estimated to be paid as follows:

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill and Intangible Assets Disclosure [Abstract]

GOODWILL AND OTHER INTANGIBLE ASSETS

NOTE 9—GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

Total goodwill of $469.4 million remained unchanged as of December 31, 2016 compared to December 31, 2015. Goodwill is tested for impairment on an annual basis as of December 31^st, or more frequently as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company’s three operating segments, Retail Banking, Commercial Banking, and Other, are equivalent to the Company’s reporting units. For complete discussion and disclosure, see Note 19 - Business Segments to the Consolidated Financial Statements.

Impairment Analysis

The Company performed its annual impairment analysis as of December 31, 2016 to determine whether and to what extent, if any, recorded goodwill was impaired. The Company used an income approach or a combined income and market approach to determine the fair value of the reporting units. Under the income approach, the Company provided a net income projection for the next three years plus a terminal growth rate that was used to calculate the discounted cash flows and the present value of the reporting units. Under the market approach, the fair value was calculated using the current fair values of comparable peer banks of similar size, geographic footprint and focus. The market capitalizations and multiples of these peer banks were used to calculate the market price of the Company and each reporting unit. The fair value was also subject to a control premium adjustment, which represents the cost savings that a purchaser of the reporting units could achieve by eliminating duplicative costs. Under the combined income and market approaches, the fair value from each approach was weighted based on management’s judgment to determine the fair value. As a result of this analysis, the Company determined that there was no goodwill impairment as of December 31, 2016 as the fair values of all reporting units exceeded the current carrying amounts of the goodwill. No assurance can be given that goodwill will not be written down in future periods.

Core Deposits Intangibles

Core deposit intangibles represent the intangible value of depositor relationships resulting from deposit liabilities assumed in various acquisitions. These intangibles are tested for impairment on an annual basis, or more frequently as events occur, or as current circumstances and conditions warrant. There were no impairment write-downs on core deposit intangibles for the years ended December 31, 2016, 2015 and 2014.

FHLB Advances

FHLB advances totaled $321.6 million and $1.02 billion as of December 31, 2016 and 2015, respectively. The FHLB advances have floating interest rates that reset monthly or quarterly based on London Interbank Offered Rate (“LIBOR”). The weighted average interest rate was 1.13% and 0.51% as of December 31, 2016 and 2015, respectively. The interest rates ranged from 0.41% to 1.27% and 0.51% to 0.63% in 2016 and 2015, respectively. As of December 31, 2016, FHLB advances that will mature in the next five years are as follows: 2017 — $0.0 million; 2018 — $0.0 million; 2019 — $80.6 million; 2020 — $0.0 million; 2021 — $0.0 million and thereafter — $241.0 million.

The Company’s available borrowing capacity from FHLB advances totaled $5.58 billion and $4.45 billion as of December 31, 2016 and 2015, respectively. The Company’s available borrowing capacity from the FHLB is derived from its portfolio of loans that are pledged to the FHLB reduced by its outstanding FHLB advances. As of December 31, 2016 and 2015, all advances were secured by real estate loans.

Junior Subordinated Debt — As of December 31, 2016, the Company has six statutory business trusts for the purpose of issuing junior subordinated debt to third party investors. The junior subordinated debt was issued in connection with the Company’s various pooled trust preferred securities offerings. The junior subordinated debt is recorded as a component of long-term debt and includes the value of the common stock issued by six of the Company’s wholly-owned subsidiaries in conjunction with these transactions. The common stock is recorded in other assets for the amount issued in connection with these junior subordinated debt issuances.

(1) All the above debt instruments are subject to call options where early redemption requires appropriate notice.

The proceeds from these issuances represent liabilities of the Company to the Trusts and are reported on the Consolidated Balance Sheets as a component of long-term debt. Interest payments on these securities are made quarterly and are deductible for tax purposes. Beginning in 2016, trust preferred securities no longer qualify as Tier I capital and are limited to Tier II capital for regulatory purposes, based on the final rules issued by the Federal Reserve (“Basel III Capital Rules”). For further discussion, see Item 1. Business — Supervision and Regulation — Capital Requirements.

Term Loan — In 2013, the Company entered into a $100.0 millionthree-year term loan agreement. The terms of the agreement were modified in 2015 to extend the term loan maturity from July 1, 2016 to December 31, 2018, where principal repayments of $5.0 million are due quarterly. The term loan bears interest at the rate of the three-month LIBOR plus 150 basis points and the weighted average interest rate was 2.24% and 1.83% for the years ended December 31, 2016 and 2015, respectively. The outstanding balance of the term loan was $40.0 million and $60.0 million as of December 31, 2016 and 2015, respectively.

INCOME TAXES

NOTE 12—INCOME TAXES

Income tax expense was $140.5 million for the year ended December 31, 2016, compared to $194.0 million and $101.1 million for years ended December 31,2015 and 2014, respectively. The effective tax rates were 24.6%, 33.5% and 22.6% for the years ended December 31,2016, 2015 and 2014, respectively. The lower effective tax rate during the year ended December 31, 2016 compared to the same period in 2015 was attributable to additional tax credits that were recognized from investments in qualified affordable housing, historic rehabilitation and renewable energy projects during the year ended December 31, 2016. The Company recognizes investment tax credits from these investments in the year the tax credits arise under the flow-through method of accounting. Included in income tax expense recognized during the years ended December 31,2016, 2015 and 2014 were $126.2 million, $67.6 million and $85.7 million, respectively, of tax credits generated from investments in qualified affordable housing partnerships and other tax credit investments.

The tax benefits of deductible temporary differences and tax carryforwards are recorded as an asset to the extent that management assesses the utilization of such temporary differences and carryforwards to be more likely than not. A valuation allowance is used, as needed, to reduce the deferred tax assets to the amount that is more likely than not to be realized. Evidence the Company considered includes the Company’s ability to generate future taxable income, implement tax-planning strategies, and utilize taxable income from prior carryback years (if such carryback is permitted under the applicable tax law), as well as future reversals of existing taxable temporary differences. The Company expects to have sufficient taxable income in future years to fully realize the deferred tax assets. Apart from this factor, the Company also performed an overall assessment by weighing all positive evidence against all negative evidence and concluded that it is more likely than not that all of the benefits of the deferred assets will be realized, with the exception of the deferred tax assets related to certain state NOL carryforwards. For states other than California, Georgia, Massachusetts and New York, since management believes that the state NOL carryforwards may not be fully utilized, a valuation allowance was recorded accordingly. The Company believes that adequate provisions have been made for all income tax uncertainties consistent with the standards of ASC 740-10. As of December 31, 2016 and 2015, the Company recorded net deferred tax assets of $129.7 million and $135.9 million, respectively, in Other assets on the Consolidated Balance Sheets.

The following table summarizes the activities related to the Company’s unrecognized tax benefits:

($ in thousands)	Year Ended December 31,
	2016			2015
Beginning Balance	$	7,125		$	5,020
Additions for tax positions of prior years	5,819			2,105
Settlements	(2,525		)	—
Ending Balance	$	10,419		$	7,125

As of December 31, 2016 and 2015, the total amount of unrecognized tax benefits that, if recognized, would favorably affect the effective income tax rate in the future was $6.8 million and $4.6 million, respectively. The Company recognizes interest and penalties, if applicable, related to the underpayment of income taxes as a component of Income Tax Expense on the Consolidated Statements of Income. The Company recorded a charge (reversal) of $6.2 million, ($460) thousand and $597 thousand of interest and penalties for the years ended December 31, 2016, 2015 and 2014, respectively. Total accrued interest and penalties included in Accrued expenses and other liabilities on the Consolidated Balance Sheets were $7.9 million and $1.8 million as of December 31, 2016 and 2015, respectively.

The foreign provision for income taxes is based on foreign pre-tax earnings of $4.5 million, $5.3 million and $12.6 million in 2016, 2015 and 2014, respectively. The Company’s consolidated financial statements provide for any related tax liability on undistributed earnings that the Company does not intend to be indefinitely reinvested outside the U.S. All of the Company’s undistributed international earnings intended to be indefinitely reinvested in operations outside the U.S. were generated by the Company’s subsidiary organized in China, which has a statutory tax rate of 25%. As of December 31, 2016, U.S. income taxes have not been provided on a cumulative total of $31.0 million of such earnings. The amount of unrecognized deferred tax liability related to these temporary differences is estimated to be $3.1 million.

Every year, subsequent to 2012, the Company has executed a Memorandum of Understanding (“MOU”) with the Internal Revenue Service (“IRS”) to voluntarily participate in the IRS Compliance Assurance Process (“CAP”). Under the CAP, the IRS audits the tax position of the Company, and identifies and resolves any tax issues that may arise throughout the tax year. The objective of the CAP is to resolve issues in a timely and contemporaneous manner and eliminate the need for a lengthy post-filing examination. Filed in September 2015, the 2014 tax return received a full acceptance of all tax matters from the IRS. The Company has executed a MOU with the IRS for the 2015 to 2017 tax years. For federal tax purposes, tax years from 2013 and beyond remain open. During the year ended December 31, 2016, the Company closed its audits for the tax years 2003 to 2008 with the California Franchise Tax Board and received a settlement of $4.7 million related to various refund claims under review. This settlement contributed to a $3.0 million income tax benefit during the year ended December 31, 2016. For California franchise tax purposes, tax years from 2009 and beyond remain open. The City of New York initiated an audit of the Company’s corporate income tax return for the 2012 to 2014 tax years in September 2016. The Company does not believe that the outcome of unresolved issues or claims in any tax jurisdiction is likely to be material to the Company’s financial position, cash flows or results of operations. The Company further believes that adequate provisions have been made for all income tax uncertainties. The Company does not anticipate that the total amount of unrecognized tax benefits will significantly change in the next twelve months.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS, CONTINGENCIES AND RELATED PARTY TRANSACTIONS

NOTE 13—COMMITMENTS, CONTINGENCIES AND RELATED PARTY TRANSACTIONS

Credit Extensions — In the normal course of business, the Company has various outstanding commitments to extend credit that are not reflected on the Consolidated Financial Statements. While the Company does not anticipate losses as a result of these transactions, commitments to extend credit are included in determining the appropriate level of the allowance for unfunded commitments and outstanding commercial and standby letters of credit (“SBLCs”). The following table summarizes the Company’s credit-related commitments as of December 31, 2016 and 2015:

($ in thousands)	December 31,
	2016		2015
Loan commitments	$	5,077,869	$	3,370,271
Commercial letters of credit and SBLCs	$	1,525,613	$	1,293,547

Loan commitments are agreements to lend to a customer provided there is no violation of any condition established in the agreement. Commitments generally have fixed expiration dates or other termination clauses and may require maintenance of compensatory balances. Of the $5.08 billion unfunded loan commitments as of December 31, 2016, approximately $2.22 billion will expire within one year or less, $2.33 billion after one year through three years, $463.9 million after three years through five years, and $63.6 million thereafter. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future funding requirements.

Commercial letters of credit are issued to facilitate domestic and foreign trade transactions while SBLCs generally are contingent upon the failure of the customers to perform according to the terms of the underlying contract with the third party. As a result, the total contractual amounts do not necessarily represent future funding requirements. The Company’s historical experience is that SBLCs typically expire without being funded. Additionally, in many cases, the Company holds collateral in various forms against these SBLCs. As part of its risk management activities, the Company monitors the creditworthiness of customers in conjunction with its SBLC exposure. Customers are obligated to reimburse the Company for any payment made on their behalf. If a customer fails to pay, the Company would, as applicable, liquidate the collateral and/or offset accounts. Total letters of credit of $1.53 billion consisted of commercial letters of credit of $46.8 million and SBLCs of $1.48 billion as of December 31, 2016. Approximately $404.2 million of total letters of credit will expire within one year or less, $588.1 million after one year through three years, $325.1 million after three years through five years, and $208.2 million thereafter.

The Company uses the same credit underwriting criteria in extending loans, commitments, and conditional obligations to customers. Each customer’s creditworthiness is evaluated on a case-by-case basis. Collateral may be obtained based on management’s assessment of the customer’s credit. Collateral may include accounts receivable, inventory, property, plant and equipment, and income-producing commercial property.

Estimated exposure to loss from these commitments is included in the allowance for unfunded credit reserves and amounted to $15.7 million and $19.8 million as of December 31, 2016 and 2015, respectively. These amounts are included in Accrued expenses and other liabilities on the Consolidated Balance Sheets.

Guarantees — The Company has sold or securitized loans with recourse in the ordinary course of business. The recourse component in the loans sold or securitized with recourse is considered a guarantee. As the guarantor, the Company is obligated to make payments when the loans default. As of December 31, 2016 and December 31, 2015, the unpaid principal balance of total single-family and multifamily loans sold or securitized with recourse amounted to $150.5 million and $191.3 million, respectively. The allowance for unfunded credit reserves is included in Accrued expenses and other liabilities on the Consolidated Balance Sheets. The Company continues to experience minimal losses from the single-family and multifamily residential loan portfolios sold or securitized with recourse.

Lease Commitments — The Company conducts a portion of its operations utilizing leased premises and equipment under operating leases. Rental expense amounted to $24.1 million, $24.6 million and $26.2 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Future minimum rental payments under non-cancellable operating leases are estimated as follows:

Years Ending December 31,	Amount ($ in thousands)
2017	$	25,334
2018	22,083
2019	18,853
2020	14,699
2021	11,617
Thereafter	31,571
Total	$	124,157

Related Party Transactions — In the ordinary course of business, the Company may enter into transactions with various related parties. The Company’s related party transactions were not material for the years ended December 31, 2016 and 2015.

Litigation — The Company is a party to various legal actions arising in the normal course of business. In accordance with ASC 450, Contingencies, the Company accrues reserves for currently outstanding lawsuits, claims, and proceedings when a loss contingency is probable and can be reasonably estimated. The outcome of such legal actions is inherently difficult to predict and it is possible that one or more of the currently pending, or threatened legal or regulatory matters could have a material adverse effect on the Company’s liquidity, consolidated financial position, and/or results of operations. Based on the information currently available, advice of counsel and established reserves, the Company believes that the eventual outcome of pending legal matters will not individually or in the aggregate have a material adverse effect on the Company’s Consolidated Financial Statements. On September 8, 2014, a jury in the case titled “F&F, LLC and 618 Investment, Inc. v. East West Bank,” Superior Court of the State of California for the County of Los Angeles, Case No. BC462714, delivered a verdict in favor of plaintiff F&F, LLC. On November 2, 2016, the Company and plaintiff entered into a settlement agreement, fully resolving and discharging this matter, whereby the Company has agreed to pay $25.0 million to the plaintiff. The litigation accrual was $25.0 million and $35.4 million as of December 31, 2016 and 2015, respectively. The $25.0 million settlement was subsequently paid to the plaintiff in January 2017.

Other Commitments — The Company has commitments to invest in qualified affordable housing partnerships and other tax credit investments qualifying for community reinvestment tax credits or other types of tax credits. These commitments are payable on demand. As of December 31, 2016 and 2015, these commitments were $174.3 million and $174.7 million, respectively. These commitments are included in Accrued expenses and other liabilities on the Consolidated Balance Sheets.

RSAs and RSUs— RSAs and RSUs are granted under our long-term incentive plan at no cost to the recipient. RSAs vest ratably over three years, cliff vest after three years, or vest at a rate of 50% each at the fourth and fifth year of continued employment from the date of the grant. RSUs vest ratably over three years or cliff vest after three or five years of continued employment from the date of the grant. RSAs and RSUs entitle the recipient to receive cash dividends equivalent to any dividends paid on the underlying common stock during the period the RSAs and RSUs are outstanding. The RSAs have non-forfeitable rights to dividends or dividend equivalents and, as such, are considered participating securities as discussed in Note 1 — Summary of Significant Accounting Policiesto the Consolidated Financial Statements. During 2015, all RSAs have vested and there were no outstanding RSAs as of December 31, 2016. While a portion of the RSAs and RSUs are time-vesting awards, others vest subject to the attainment of specified performance goals. All RSAs and RSUs are subject to forfeiture until vested.

The following table presents a summary of the activity for the Company’s time-based and performance-based RSUs during the year ended December 31, 2016 based on the target amount of awards:

	2016
	Time-Based RSUs				Performance-Based RSUs
	Shares		Weighted Average Grant Date Fair Value		Shares		Weighted Average Grant Date Fair Value
Outstanding at beginning of year	933,312		$	36.83	389,358		$	34.21
Granted	529,385		31.86		159,407		29.18
Vested	(125,608	)	25.78		(138,019	)	25.25
Forfeited	(118,375	)	35.80		—		—
Outstanding at end of year	1,218,714		$	35.92	410,746		$	35.27

The weighted average fair values of the time-based awards granted during 2016, 2015 and 2014 were $31.86, $40.36 and $36.59, respectively. The weighted average fair value of the performance-based awards granted during the year ended December 31, 2016, 2015 and 2014 were $29.18, $41.15 and $36.85, respectively. The total fair value of time-based awards that vested during 2016, 2015 and 2014 was $4.2 million, $9.1 million and $21.6 million, respectively. The total fair value of performance-based awards that vested during 2016, 2015 and 2014 was $4.4 million, $5.8 million and $3.1 million, respectively.

Compensation costs for the time-based awards are based on the quoted market price of the Company’s stock at the grant date. Compensation costs for performance-based awards are based on the grant date fair value of the performance-based awards which considers both market and performance conditions. The associated compensation expense of the performance-based awards fluctuates with the estimated outcome of meeting the performance condition, where the total amount of compensation expense recognized on these awards will be finalized upon vesting of such awards.

Compensation costs of both time-based and performance-based awards are recognized on a straight-line basis from the grant date until the vesting date of each grant. As of December 31, 2016, total unrecognized compensation cost related to time-based and performance-based RSUs amounted to $21.9 million and $9.6 million, respectively. This cost is expected to be recognized over a weighted average period of 1.84 years and 1.71 years, respectively.

Stock Purchase Plan — The 1998 Employee Stock Purchase Plan (the “Purchase Plan”) provides eligible employees of the Company the right to purchase shares of its common stock at a discount. Employees could purchase shares at 90% of the fair market price subject to an annual purchase limitation of $22,500 per employee. As of December 31, 2016, the Purchase Plan qualifies as a non-compensatory plan under Section 423 of the Internal Revenue Code and, accordingly, no compensation expense has been recognized. 2,000,000 shares of the Company’s common stock have been made available for sale under the Purchase Plan. During 2016 and 2015, 67,198 shares totaling $2.1 million and 55,485 shares totaling $2.0 million, respectively, have been sold to employees under the Purchase Plan. As of December 31, 2016, there were 572,030 shares available under the Purchase Plan.

The Company’s contributions to the Plan are determined annually by the Board of Directors (the “Board”) in accordance with the Plan requirements. Plan participants become vested in the matching contributions received from the Plan sponsor at the rate of 20% per year for each full year of service after the first year such that the Plan participants become 100% vested after five years of credited service. For the Plan years ended December 31, 2016, 2015 and 2014, the Company expensed $8.4 million, $7.5 million and $5.9 million, respectively.

REGULATORY REQUIREMENTS AND MATTERS

Banking and Thrift [Abstract]

REGULATORY REQUIREMENTS AND MATTERS

NOTE 18 — REGULATORY REQUIREMENTSAND MATTERS

Capital Adequacy — The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. The Bank is a member bank of the Federal Reserve System and the Federal Reserve Bank is the Bank’s primary regulator. In July 2013, the Federal Reserve Bank published Basel III Capital Rules establishing a new comprehensive capital framework for U.S. banking organizations based upon the 1988 capital accord (“Basel I”) of the Basel Committee on Banking Supervision. The Basel III Capital Rules apply to all depository institutions and top-tier bank holding companies with assets of $500.0 million or more, and accordingly are effective for the Company and the Bank on January 1, 2015 (subject to phase-in periods for certain of their components). The Basel III Capital Rules: (i) introduced a new capital measure called Common Equity Tier I Risk-based Capital (“CET1”) and a related regulatory capital ratio of CET1 to risk-weighted assets; (ii) specified that Tier I capital consists of CET1 and “Additional Tier I capital” instruments, which are instruments treated as Tier I instruments under the prior capital rules that meet certain revised requirements; (iii) mandated that most deductions or adjustments to regulatory capital measures be made to CET1 and not to the other components of capital; and (iv) expanded the scope of the deductions from and adjustments to capital, compared to existing regulations. The Basel III Capital Rules also prescribed a new standardized approach for risk weightings that expanded the risk weighting categories from the previous four Basel I-derived categories (0%, 20%, 50% and 100%) to a larger and more risk-sensitive number of categories.

The Federal Deposit Insurance Corporation Improvement Act of 1991 requires that the federal regulatory agencies adopt regulations defining capital tiers for banks: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. The Basel III Capital Rule requires that banking organizations maintain a minimum CET1 ratio of 4.5%, a Tier I capital ratio of 6.0%, and a total capital ratio of 8.0% to be considered adequately capitalized. Failure to meet minimum capital requirements can result in certain mandatory actions and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s Consolidated Financial Statements.

As of December 31, 2016 and 2015, the Company and the Bank were both categorized as well capitalized based on applicable U.S. regulatory capital ratio requirements in accordance with Basel III standardized approaches, as set forth in the table below. The Company believes that no changes in conditions or events have occurred since December 31, 2016, which would result in changes that would cause the Company or the Bank to fall below the well capitalized level. The following tables present the regulatory capital information of the Company and the Bank as of December 31, 2016 and 2015:

Reserve Requirement — The Bank is required to maintain a percentage of its deposits as reserves at the Federal Reserve Bank of San Francisco (the “FRB”). The daily average reserve requirement was approximately $503.8 million and $395.6 million as of December 31, 2016 and 2015, respectively.

Regulatory Matters — The Bank entered into a Written Agreement, dated November 9, 2015, with the FRB (the “Written Agreement”), to correct less than satisfactory Bank Secrecy Act (“BSA”) and Anti-Money Laundering (“AML”) programs detailed in a joint examination by the FRB and the California Department of Business Oversight (“DBO”). The Bank also entered into a related MOU with the DBO. The Written Agreement, among other things, requires the Bank to:

• within 60 days of the Written Agreement, submit a written plan to strengthen the Board’s oversight of the Bank’s compliance with the applicable laws, rules and regulations relating to AML, including compliance with the BSA, the rules and regulations issued thereunder by the U.S. Department of Treasury, and the AML requirements of Regulation H of the Board of Governors (collectively, “BSA/AML Requirements”);

• within 60 days of the Written Agreement, submit a written revised program for compliance with all applicable BSA/AML Requirements, which, at a minimum, will include, among other things, a system of internal controls to ensure compliance with all applicable BSA/AML Requirements and controls designed to ensure compliance with all applicable requirements relating to correspondent accounts for foreign financial institutions;

• within 60 days of the Written Agreement, submit a written revised program for conducting appropriate levels of customer due diligence, including policies, procedures, and controls to ensure that the Bank collects, analyzes, and retains complete and accurate customer information for all account holders, including customers of the Bank’s foreign operations;

• within 60 days of the Written Agreement, submit an enhanced written program to reasonably ensure the identification and timely, accurate and complete reporting by the Bank of all known or suspected violations of law or suspicious transactions to law enforcement and supervisory authorities as required by applicable suspicious activity reporting laws and regulations;

• within 60 days of the Written Agreement, submit a written plan to the FRB for the full installation, testing, and activation of an effective automated transaction monitoring system to reasonably ensure the identification and timely, accurate, and complete reporting by the Bank of all known or suspected violations of law or suspicious transactions to law enforcement and supervisory authorities;

• within 30 days following completion of the customer account remediation required by the Written Agreement, engage an independent consultant to conduct a review of, and prepare a report detailing findings relating to, account and transaction activity associated with any high risk customer accounts during a six-month period in 2014 to determine whether suspicious activity involving high risk customer accounts or transactions was properly identified and reported; and

• within 60 days of the Written Agreement, submit a plan to enhance the Bank’s compliance with Office of Foreign Assets Control (“OFAC”) Regulations, including enhanced OFAC screening procedures and an improved methodology for assessing OFAC risks.

The Company believes that the Bank is making progress in executing the compliance plans and programs required by the Written Agreement and MOU, although there can be no assurances that our plans and progress will be found to be satisfactory by our regulators. To date, the Bank has added significant resources to meet the monitoring and reporting obligations imposed by the Written Agreement and will continue to require significant management and third party consultant resources to comply with the Written Agreement and MOU, and to address any additional findings or recommendations by the regulators. These incremental administrative and third party costs, as well as the operational restrictions imposed by the Written Agreement, may adversely affect the Bank’s results of operations.

If additional compliance issues are identified or if the regulators determine that the Bank has not satisfactorily complied with the terms of the Written Agreement, the regulators could take further actions with respect to the Bank and, if such further actions were taken, such actions could have a material adverse effect on the Bank. The operating and other conditions of the Written Agreement could lead to an increased risk of being subject to additional regulatory actions by the DBO or FRB or other government agencies, as well as additional actions resulting from future regular annual safety and soundness and compliance examinations by the federal and state regulators that downgrade the regulatory ratings of the Bank.

Segment Reporting [Abstract]

BUSINESS SEGMENTS

NOTE 19—BUSINESS SEGMENTS

The Company utilizes an internal reporting system to measure the performance of various operating segments within the Bank and the Company. The Company has identified three operating segments for purposes of management reporting: (1) Retail Banking; (2) Commercial Banking; and (3) Other. These three business divisions meet the criteria of an operating segment: the segment engages in business activities from which it earns revenues and incurs expenses, its operating results are regularly reviewed by the Company’s chief operating decision-maker to render decisions about resources to be allocated to the segment and assess its performance and discrete financial information is available.

The Retail Banking segment focuses primarily on retail operations through the Bank’s branch network. The Commercial Banking segment, which includes CRE, primarily generates commercial loans through the commercial lending offices located in the Bank’s production offices. Furthermore, the Company’s Commercial Banking segment offers a wide variety of international finance and trade services and products. The remaining centralized functions, including treasury activities and eliminations of inter-segment amounts, have been aggregated and included in the “Other” segment, which provides broad administrative support to the two core segments.

The Company’s internal funds transfer pricing assumptions are intended to promote core deposit growth and to reflect the current risk profiles of various loan categories within the credit portfolio. Internal transfer pricing assumptions and methodologies are reviewed at least annually to ensure that the Company’s process is reflective of current market conditions. The internal transfer pricing process is formulated with the goal of incenting loan and deposit growth that is consistent with the Company’s overall growth objectives, as well as to provide a reasonable and consistent basis for the measurement of the Company’s business segments and product net interest margins.

The accounting policies of the segments are the same as those described in Note 1 — Summary of Significant Accounting Policiesto the Consolidated Financial Statements. Operating segment results are based on the Company’s internal management reporting process, which reflects assignments and allocations of certain operating and administrative costs and the provision for credit losses. Net interest income is based on the Company’s internal funds transfer pricing system which assigns a cost of funds or a credit for funds to assets or liabilities based on their type, maturity or repricing characteristics. Noninterest income and noninterest expense, including depreciation and amortization, directly attributable to a segment are assigned to that business segment. Indirect costs, including overhead expense, are allocated to the segments based on several factors, including, but not limited to, full-time equivalent employees, loan volume and deposit volume. The provision for credit losses is allocated based on actual charge-offs for the period as well as average loan balances for each segment during the period. The Company evaluates overall performance based on profit or loss from operations before income taxes excluding nonrecurring gains and losses.

Changes in the Company’s management structure or reporting methodologies may result in changes in the measurement of operating segment results. Results for prior periods are generally restated for comparability for changes in management structure or reporting methodologies unless it is not deemed practicable to do so.

The following tables present the operating results and other key financial measures for the individual operating segments as of and for the years ended December 31, 2016, 2015 and 2014:

PARENT COMPANY CONDENSED FINANCIAL STATEMENTS

NOTE 20—PARENT COMPANY CONDENSED FINANCIAL STATEMENTS

The principal sources of East West’s income (on a parent company-only basis) are dividends from the Bank.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2016

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation — The accounting and reporting policies of the Company conform with United States Generally Accepted Accounting Principles (“U.S. GAAP”) and general practices in the banking industry. To prepare the Consolidated Financial Statements in conformity with U.S. GAAP, management must make estimates based on conditions that affect the reported amounts of assets and liabilities as of the date of the Consolidated Financial Statements and income and expenses during the reporting period and the related disclosures. Actual results could differ from those estimates. Certain items on the Consolidated Financial Statements and notes for the prior years have been reclassified to conform to the 2016 presentation.

Principles of Consolidation

Principles of Consolidation — The Consolidated Financial Statements include the accounts of East West and its wholly owned subsidiaries, East West Bank and East West Insurance Services, Inc. Intercompany transactions and accounts have been eliminated in consolidation. East West also has six wholly-owned subsidiaries that are statutory business trusts (the “Trusts”), one of which was the result of the acquisition of MetroCorp during the three months ended March 31, 2014, as discussed in Note 2—Business Combination to the Consolidated Financial Statements. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, the Trusts are not included on the Consolidated Financial Statements.

Cash and Cash Equivalents

Cash and Cash Equivalents — Cash and cash equivalents include cash on hand, cash items in transit, cash due from the Federal Reserve Bank and other financial institutions, and federal funds sold with original maturities up to three months.

Interest-bearing Deposits with Banks

Interest-bearing Deposits with Banks — Interest-bearing deposits with banks include cash placed with other banks with original maturities greater than three months and less than one year.

Resale Agreements and Repurchase Agreements

Resale Agreements and Repurchase Agreements — Resale agreements are recorded at the balances at which the securities were acquired. The market values of the underlying securities collateralizing the related receivable of the resale agreements, including accrued interest, are monitored. Additional collateral may be requested by the Company from the counterparty when deemed appropriate. Repurchase agreements are accounted for as collateralized financing transactions and recorded at the balances at which the securities were sold. The Company may have to provide additional collateral for the repurchase agreements, as necessary. Collateral accepted includes securities that are not recognized on the Consolidated Balance Sheets. Collateral pledged consists of securities that are not netted on the Consolidated Balance Sheets against the related collateralized liability. Collateral accepted or pledged in resale and repurchase agreements with other financial institutions may also be sold or re-pledged by the secured party but is usually delivered to and held by the third party trustees. The Company has elected to offset resale and repurchase transactions with the same counterparty on the Consolidated Balance Sheets when it has a legally enforceable master netting agreement and when the transactions are eligible for netting under ASC 210-10-45.

Available-for-Sale Investment Securities

Available-for-SaleInvestment Securities — The Company holds debt securities and marketable equity securities in its investment portfolio. These securities are classified as available-for-sale investment securities and reported at fair value. Unrealized gains and losses, after applicable income taxes, are reported in other comprehensive income. Amortization of premiums and accretion of discounts on available-for-sale investment securities are recorded as yield adjustments on such securities using the effective interest method. The specific identification method is used for determining cost in computing realized gains and losses on available-for-sale investment securities sold.

For each reporting period, all securities that are in an unrealized loss position are analyzed as part of the Company’s ongoing assessment of other-than-temporary impairment (“OTTI”). In determining whether an impairment is other than temporary, the Company considers the severity and duration of the decline in fair value, the length of time expected for recovery, the financial condition of the issuer, changes in the securities’ ratings and other qualitative factors, as well as whether the Company either plans to sell the security or it is more-likely-than-not that it will be required to sell the security before recovery of the amortized cost. If the impairment of the available-for-sale debt security is credit-related, an OTTI loss is recorded on the Consolidated Statements of Income. Otherwise, the non-credit-related impairment loss is recorded in other comprehensive income. If the Company intends to sell an available-for-sale debt security or believes it will be more-likely-than-not required to sell a security, the Company records the full amount of the impairment loss as an OTTI loss. Available-for-sale marketable equity securities are carried at fair value with net unrealized gains and losses included in other comprehensive income on an after-tax basis. If there is an other-than-temporary decline in the fair value of any individual available-for-sale marketable equity security, the cost basis is reduced and the Company reclassifies the associated net unrealized loss out of other comprehensive income with a corresponding charge to the Consolidated Statements of Income.

Loans Held-for-Sale

Loans Held-for-Sale — Loans held-for-sale are carried at lower of cost or fair value. When a determination is made at the time of commitment to originate or purchase loans as held-for-investment, it is the Company’s intent to hold these loans to maturity or for the “foreseeable future,” subject to periodic review under the Company’s management evaluation processes, including asset/liability management. When the Company subsequently changes its intent to hold certain loans, the loans are transferred from the loans held-for-investment portfolio to the loans held-for-sale portfolio at lower of cost or fair value. Loan origination fees on loans held-for-sale, net of certain costs of processing and closing the loans, are deferred until the time of sale and are included in computing gains or losses from the sales of the related loans. If the loan or a portion of the loan cannot be sold, it is subsequently transferred back into the loans held-for-investment portfolio from the loans held-for-sale portfolio at lower of cost or fair value on the transfer date. A valuation allowance is established if the fair value of such loans is lower than their cost, with a corresponding charge to noninterest income.

Loans Held-for-Investment

Loans Held-for-Investment — Loans receivable that the Company has the intent and ability to hold for the foreseeable future or until maturity are stated at their outstanding principal, reduced by an allowance for loan losses and net of deferred loan fees or costs on originated loans and unamortized premiums or discounts on purchased loans. Nonrefundable fees and direct costs associated with the origination or purchase of loans are deferred and netted against outstanding loan balances. The deferred net loan fees and costs are recognized in interest income as an adjustment to yield over the loan term using the effective interest method or straight-line method. Discounts or premiums on purchased loans are accreted or amortized to interest income using the effective interest method or straight-line method over the remaining period to contractual maturity. Interest on loans is calculated using the simple-interest method on daily balances of the principal amounts outstanding. Generally, loans are placed on nonaccrual status when they become 90 days past due. Loans are considered past due when contractually required principal or interest payments have not been made on the due dates. Loans are also placed on nonaccrual status when management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that full collection of principal or interest becomes uncertain, regardless of the length of past due status. Once a loan is placed on nonaccrual status, interest accrual is discontinued and all unpaid accrued interest is reversed against interest income. Interest payments received on nonaccrual loans are reflected as a reduction of principal and not as interest income. A loan is returned to accrual status when the borrower has demonstrated a satisfactory payment trend subject to management’s assessment of the borrower’s ability to repay the loan.

Troubled Debt Restructurings

Troubled Debt Restructurings — A loan is classified as a troubled debt restructuring (“TDR”) when the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower that the Company would not otherwise consider. The concessions may be granted in various forms, including a below-market change in the stated interest rate, a reduction in the loan balance or accrued interest, an extension of the maturity date with a stated interest rate lower than the current market rate or note splits referred to as A/B note restructurings. In A/B note restructurings, the original note is bifurcated into A and B notes. The A note represents the portion of the modified original loan which allows for acceptable loan-to-value and debt coverage on the collateral and is expected to be collected in full. The B note represents the portion of the original loan where there is a shortfall in value and is fully charged off. The A/B note balance after the restructuring is comprised of the A note balance only, as the B note would have been charged off. A notes are not disclosed as TDRs in subsequent years after the year of restructuring, if the restructuring agreement specifies an interest rate equal to or greater than the rate that the Company was willing to accept at the time of the restructuring for a new loan with comparable risk; the loan is not impaired based on the terms specified by the restructuring agreement; and has demonstrated a period of sustained performance under the modified terms.

TDRs may be designated as performing or nonperforming. A TDR may be designated as performing if the loan has demonstrated sustained performance under the modified terms. The period of sustained performance may include the periods prior to modification, if prior performance has met or exceeded the modified terms. A loan will remain on nonaccrual status until the borrower demonstrates a sustained period of performance. TDRs are included in the impaired loan quarterly valuation allowance process. Refer to Impaired Loans below for a complete discussion.

Impaired Loans

Impaired Loans — The Company’s loans are grouped into heterogeneous and homogeneous (mostly consumer loans) categories. Classified loans in the heterogeneous category are identified and evaluated for impairment on an individual basis. A loan is considered impaired when, based on current information and events, it is probable that the Company will not be able to collect all scheduled payments of principal or interest due in accordance with the original contractual terms of the loan agreement. Factors considered by management in determining and measuring loan impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of and the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as appropriate, at the loan’s observable market price or the fair value of the collateral, if the loan is collateral dependent, less costs to sell. When the value of an impaired loan is less than the recorded investment and the loan is classified as nonperforming and uncollectible, the deficiency is charged off against the allowance for loan losses. If the loan is a performing TDR, the deficiency is included in the specific reserves of the allowance for loan losses, as appropriate. Payments received on impaired loans on nonaccrual status are not recognized in interest income, but are applied as a reduction to the principal outstanding. The Company’s impaired loans include predominantly non-purchased credit impaired (“non-PCI”) loans held-for-investment on nonaccrual status and any non-PCI loans modified as a TDR, on either accrual or nonaccrual status.

Allowance for Credit Losses

Allowance for Credit Losses — The allowance for credit losses consists of the allowance for loan losses and the allowance for unfunded credit reserves. Unfunded credit reserves include reserves provided for unfunded lending commitments, unissued standby letters of credit and recourse obligations for loans sold. The allowance for loan losses is established as management’s estimate of probable losses inherent in the Company’s lending activities. The allowance for loan losses is increased by the provision for loan losses and decreased by net charge-offs when management believes the uncollectability of a loan is probable. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated monthly by management based on management’s periodic review of the collectability of the loans.

The allowance for loan losses on non-PCI loans consists of specific reserves and general reserves. The Company’s non-PCI loans fall into heterogeneous and homogeneous categories. Impaired loans are subject to specific reserves. Loans in the homogeneous category, as well as non-impaired loans in the heterogeneous category, are evaluated as part of the general reserves. General reserves are calculated by utilizing both quantitative and qualitative factors. There are different qualitative risks for the loans in each portfolio segment. Predominant risk characteristics of the residential and commercial real estate (“CRE”) segments are the collateral and geographic locations of the properties collateralizing the loans. Predominant risk characteristics of the commercial and industrial (“C&I”) segment are the global cash flows of the borrowers and guarantors, as well as the economic and market conditions. Consumer loans are largely comprised of home equity lines of credit (“HELOCs”) and the predominant risk characteristic is the real estate collateral securing the loans.

The Company also maintains an allowance for loan losses on purchased credit impaired (“PCI”) loans when there is deterioration in credit quality subsequent to acquisition. Based on the Company’s estimates of cash flows expected to be collected, the Company establishes an allowance for the PCI loans, with a charge to Provision for credit losses on the Consolidated Statements of Income. 

When determined uncollectible, it is the Company’s policy to promptly charge off the difference of the outstanding loan balance and the fair value of the collateral or the discounted value of expected cash flows. Recoveries are recorded when payment is received on loans that were previously charged off through the allowance for loan losses. Allocation of a portion of the allowance to one segment of the loan portfolio does not preclude its availability to absorb losses in other segments.

The allowance for unfunded credit reserves is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities, including an assessment of the probability of commitment usage, credit risk factors for loans outstanding, and the terms and expiration dates of the unfunded credit facilities. The allowance for loan losses is reported separately on the Consolidated Balance Sheets, whereas the allowance for unfunded credit reserves is included in Accrued expenses and other liabilities on the Consolidated Balance Sheets. The provision for credit losses is reported on the Consolidated Statements of Income.

Credit Quality Indicators

All loans are subject to the Company’s internal and external credit review and monitoring. Loans are risk rated based on an analysis of the current state of the borrower’s credit quality. The analysis of credit quality includes a review of all repayment sources, the borrower’s current payment performance/delinquency, current financial and liquidity status and all other relevant information.  For single-family residential loans, payment performance/delinquency is the driving indicator for the risk ratings.  Risk ratings are the overall credit quality indicator for the Company and the credit quality indicator utilized for estimating the appropriate allowance for loan losses. The Company utilizes a risk rating system, which can be classified within the following categories: Pass, Watch, Special Mention, Substandard, Doubtful and Loss. The risk ratings reflect the relative strength of the repayment sources.

Pass and Watch loans are generally considered to have sufficient sources of repayment in order to repay the loan in full in accordance with all terms and conditions. These borrowers may have some credit risks that require monitoring, but full repayments are expected. Special Mention loans are considered to have potential weaknesses that warrant closer attention by management. Special Mention is considered a transitory grade. If potential weaknesses are resolved, the loan is upgraded to a Pass or Watch grade. If negative trends in the borrower’s financial status or other information indicates that the repayment sources may become inadequate, the loan is downgraded to a Substandard grade. Substandard loans are considered to have well-defined weaknesses that jeopardize the full and timely repayment of the loan. Substandard loans have a distinct possibility of loss, if the deficiencies are not corrected. Additionally, when management has assessed a potential for loss but a distinct possibility of loss is not recognizable, the loan is still classified as Substandard. Doubtful loans have insufficient sources of repayment and a high probability of loss. Loss loans are considered to be uncollectible and of such little value that they are no longer considered bankable assets. These internal risk ratings are reviewed routinely and adjusted based on changes in the borrowers’ financial status and the loans’ collectability.

PCI Loans

PCI Loans — Acquired loans are recorded at fair value as of acquisition date in accordance with ASC 805, Business Combinations. A purchased loan is deemed to be credit impaired when there is evidence of credit deterioration since its origination and it is probable at the acquisition date that the Company would be unable to collect all contractually required payments and is accounted for under ASC 310-30, Receivables — Loans and Debt Securities Acquired with Deteriorated Credit Quality. Under ASC 310-30, loans are recorded at fair value at acquisition date, factoring in credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for loan losses is not carried over or recorded as of the acquisition date.

The amount of expected cash flows over the initial investment in the loan represents the “accretable yield,” which is recognized as interest income on a level yield basis over the life of the loan. The excess of total contractual cash flows over the cash flows expected to be received at origination is deemed the “nonaccretable difference.” In estimating the nonaccretable difference, the Company (a) calculates the contractual amount and timing of undiscounted principal and interest payments (the “undiscounted contractual cash flows”) and (b) estimates the amount and timing of undiscounted expected principal and interest payments (the “undiscounted expected cash flows”). The cash flows expected over the life of the pools are estimated by an internal cash flow model that projects cash flows and calculates the carrying values of the pools, book yields, effective interest income and impairment, if any, based on pool level events. Assumptions such as cumulative loss rates, loss curves and prepayment speeds are utilized to calculate the expected cash flows. The difference between the undiscounted contractual cash flows and the undiscounted expected cash flows is the nonaccretable difference. Subsequent to the acquisition date, any increases in expected cash flows over the expected cash flows at purchase date in excess of fair value that are significant and probable are adjusted through the accretable yield on a prospective basis. Any subsequent decreases in expected cash flows over the expected cash flows at purchase date that are probable are recognized by a charge to the provision for loan losses. Any disposals of loans, including sales of loans, payments in full or foreclosures, result in the removal of the loan from the ASC 310-30 portfolio at the carrying amount.

At the date of acquisition, PCI loans are pooled and accounted for at fair value, which represents the discounted value of the expected cash flows of the loan portfolio. A pool is accounted for as a single asset with a single interest rate, cumulative loss rate and cash flow expectation. The cash flows expected over the life of the pools are estimated by an internal cash flow model that projects cash flows and calculates the carrying values of the pools, book yields, effective interest income and impairment, if any, based on pool level events. Assumptions as to cumulative loss rates, loss curves and prepayment speeds are utilized to calculate the expected cash flows. The amount of expected cash flows over the initial investment in the loan represents the “accretable yield,” which is recognized as interest income on a level yield basis over the life of the loan. Prepayments affect the estimated life of PCI loans, which may change the amount of interest income, and possibly principal, expected to be collected. The excess of total contractual cash flows over the cash flows expected to be received at origination is deemed to be the “nonaccretable difference.”

Investments in Qualified Affordable Housing Partnerships, Tax Credit and Other Investments, Net

Investments in Qualified Affordable Housing Partnerships, Tax Credit and Other Investments, Net — The Company records the investments in qualified affordable housing partnerships, net, using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the amortization on the Consolidated Statements of Income as a component of Income tax expense. The Company records investments in tax credit and other investments, net, using either the equity method or cost method of accounting. The tax credits are recognized on the Consolidated Financial Statements to the extent they are utilized on the Company’s income tax returns. The investments are reviewed for impairment on an annual basis or on an interim basis, if an event occurs that would trigger potential impairment.

The Company records its investments in qualified affordable housing partnerships, net, using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the amortization on the Consolidated Statements of Income as a component of income tax expense.

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets — Goodwill represents the excess of the purchase price over the fair value of net assets acquired in various past acquisitions. Goodwill is not amortized and is reviewed for impairment on an annual basis or on an interim basis, if an event occurs or circumstances change that would reduce the fair value of a reporting unit below its carrying value. Core deposit intangibles, which represent the intangible value of depositor relationships resulting from deposit liabilities assumed in acquisitions, are amortized over the projected useful lives of the deposits, which is typically 7 to 15 years. Core deposit intangibles are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment on goodwill and core deposit intangibles is recognized by writing down the asset as a charge to noninterest expense to the extent that the carrying value exceeds the estimated fair value.

Goodwill is tested for impairment on an annual basis as of December 31^st, or more frequently as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount.

Core deposit intangibles represent the intangible value of depositor relationships resulting from deposit liabilities assumed in various acquisitions. These intangibles are tested for impairment on an annual basis, or more frequently as events occur, or as current circumstances and conditions warrant

The Company performed its annual impairment analysis as of December 31, 2016 to determine whether and to what extent, if any, recorded goodwill was impaired. The Company used an income approach or a combined income and market approach to determine the fair value of the reporting units. Under the income approach, the Company provided a net income projection for the next three years plus a terminal growth rate that was used to calculate the discounted cash flows and the present value of the reporting units. Under the market approach, the fair value was calculated using the current fair values of comparable peer banks of similar size, geographic footprint and focus. The market capitalizations and multiples of these peer banks were used to calculate the market price of the Company and each reporting unit. The fair value was also subject to a control premium adjustment, which represents the cost savings that a purchaser of the reporting units could achieve by eliminating duplicative costs. Under the combined income and market approaches, the fair value from each approach was weighted based on management’s judgment to determine the fair value.

Premises and Equipment, net

Premises and Equipment, net — The Company’s premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed based on the straight-line method over the estimated useful lives of the various classes of assets. The ranges of estimated useful lives for the principal classes of assets are as follows:

Buildings and building improvements	25 years
Furniture, fixtures and equipment	3 to 7 years
Leasehold improvements	Term of lease or useful life, whichever is shorter

The Company reviews its long-lived assets for impairment annually or when events or changes in circumstances indicate that the carrying amounts of these assets may not be recoverable. An asset is considered impaired when the fair value, which is the expected undiscounted cash flows over the remaining useful life, is less than the net book value. The excess of the net book value over its fair value is charged as impairment loss to noninterest expense.

Long-Term Debt

Long-Term Debt — Long-term debt consists of junior subordinated debt and a term loan. The Trusts issued both fixed and variable rate capital securities, representing undivided preferred beneficial interests in the assets of the Trusts, to third party investors. The Company is the owner of all the beneficial interests represented by the common securities of the Trusts. The purpose of issuing the capital securities was to provide the Company with a cost-effective means of obtaining Tier I capital for regulatory reporting purposes. Since the beginning of 2016, pursuant to the Basel III Capital Rules under Dodd-Frank Wall Street Reform and Consumer Protection Act, trust preferred securities have been fully phased out of Tier I capital and are now qualified as Tier II capital.

Income Taxes

Income Taxes — The Company files consolidated federal income tax returns, foreign tax returns, and various combined and separate company state tax returns. The calculation of the Company's income tax provision and related tax accruals requires the use of estimates and judgments.

Accrued income tax liabilities (assets) represent the estimated amounts due to (receivable from) the various taxing jurisdictions where the Company has established a business presence.

Deferred tax assets and liabilities are recognized for the expected future tax consequences of existing temporary differences between the financial reporting and tax reporting basis of assets and liabilities using enacted tax laws and rates and tax carryforwards. To the extent a deferred tax asset is no longer expected more likely than not to be realized, a valuation allowance is established. See Note 12— Income Taxes for discussion of management assessment of evidence considered by the Company in establishing a valuation allowance.

The Company established an allowance for potential taxes, interest and penalties related to uncertain tax positions. This contingent reserve is estimated based on facts and circumstances, including the interpretation of existing law, new judicial or regulatory guidance, and the status of tax audits.

Stock-Based Compensation

Stock-Based Compensation — The Company issues stock-based awards to certain employees, officers and directors, and accounts for the related costs in accordance with the provisions of ASC 505, Equity, and ASC 718, Compensation — Stock Compensation. Stock-based compensation cost is measured at the grant date based on the fair value of the awards, and expensed over the employee’s requisite service period.

The Company grants nonqualified stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”), which include service conditions for vesting. Additionally, some of the Company’s RSAs and RSUs contain performance conditions required to be met in order for the awards to vest. The stock option awards vest between three to four years from the grant date. RSAs vest ratably over three years, cliff vest after three years, or vest at a rate of 50% each at the fourth and fifth year of continued employment from the date of the grant. RSUs vest ratably over three years or cliff vest after three or five years of continued employment from the date of the grant. Compensation expense is amortized on a straight-line basis over the requisite service period for the entire award, which is generally the maximum vesting period of the award.

The fair values of stock options are estimated using the Black-Scholes option pricing model on the grant date. For time-based RSAs and RSUs, the grant-date fair values are measured at the fair value of the Company’s common stock as if the RSAs or RSUs are vested and issued on the date of grant. For performance based RSAs and RSUs, the grant date fair value considers both performance and market conditions (where applicable). As stock-based compensation expense is estimated based on awards ultimately expected to vest, it is reduced by the expense related to awards expected to be forfeited. Forfeitures are estimated at the time of grant and are reviewed annually for reasonableness. If the estimated forfeitures are revised, a cumulative effect of changes in estimated forfeitures for current and prior periods is recognized in compensation expense in the period of change.

EPS

EPS — Basic EPS is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during each period, plus common share equivalents calculated for stock options, warrants and RSUs outstanding using the treasury stock method. The Company has issued RSAs, which are unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents. These RSAs are considered participating securities. Accordingly, the Company applied the two-class method in the computation of basic and diluted EPS in the periods when the RSAs were outstanding. RSUs do not contain nonforfeitable rights to dividends when granted.

Derivatives

Derivatives — As part of the asset and liability management strategy, the Company uses derivative financial instruments to mitigate exposure to interest rate and foreign currency risks.  Derivatives utilized by the Company include swaps, forwards and option contracts.  All derivative instruments are included in Other assets or Other liabilities on the Consolidated Balance Sheets at fair value. The related cash flows are recognized on the Cash flows from operating activities section on the Consolidated Statement of Cash Flows. The Company uses its accounting hedges based on the exposure being hedged as either fair value hedges or hedges of the net investments in certain foreign operations. Changes in fair value of derivatives designated as fair value hedges are reported in Interest expense on the Consolidated Statements of Income.  Changes in fair value of derivatives used as hedges of the net investments in foreign operations, to the extent effective, are recorded as a component of AOCI. The change in fair value attributable to the ineffective portion of the hedging instrument is recognized immediately in Noninterest income on the Consolidated Statements of Income. For all other derivatives, changes in fair value are recognized on the Consolidated Statements of Income.

All derivatives designated as fair value hedges and hedges of the net investments in certain foreign operations are linked to specific hedged items or to groups of specific assets and liabilities on the Consolidated Balance Sheets.  To qualify as an accounting hedge under the hedge accounting rules (versus an economic hedge where hedge accounting is not sought), a derivative must be highly effective in offsetting the risk designated as being hedged.  The Company formally documents its hedge relationships at inception, including identification of the hedging instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction at the time the derivative contract is executed. Quarterly after the inception, the Company assesses whether the derivatives used in hedging transactions are highly effective in offsetting changes in the fair value of the hedged items.  Retroactive effectiveness is also assessed, as well as the continued expectation that the hedge will remain effective prospectively. 

The Company discontinues hedge accounting prospectively when (i) a derivative is no longer highly effective in offsetting changes in the fair value; (ii) a derivative expires or is sold, terminated, or exercised, or (iii) the Company determines that designation of a derivative as a hedge is no longer appropriate.  If a fair value hedge is discontinued, the derivative will continue to be recorded on the Consolidated Balance Sheets at its fair value with changes in fair value included on the Consolidated Statements of Income. When the hedged net investment is either sold or substantially liquidated, the effective portion of the changes in the fair value of the derivatives are reclassified out of AOCI into Foreign exchange income on the Consolidated Statements of Income.

The Company also offers various interest rate and foreign currency derivative products to customers and enters into derivative transactions in due course. These transactions are not linked to specific Company’s assets or liabilities on the Consolidated Balance Sheets or to forecasted transactions in a hedge relationship and, therefore, do not qualify for hedge accounting. The contracts are marked-to-market at the end of each reporting period with changes in fair value recorded on the Consolidated Statements of Income.

Fair Value

Fair Value — Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and, in many cases, requires management to make a number of significant judgments. Based on the observable inputs used in the valuation techniques, the Company classifies its assets and liabilities measured and disclosed at fair value in accordance with a three-level hierarchy (e.g., Level 1, Level 2 and Level 3) established under ASC 820, Fair Value Measurements. The Company records certain financial instruments, such as available-for-sale investment securities, and derivative assets and liabilities, at fair value on a recurring basis. Certain financial statement line items such as impaired loans, loans held-for-sale and OREO are recorded at fair value on a nonrecurring basis. Nonrecurring fair value measurements generally involve assets that are periodically evaluated for impairment.

Foreign Currency Translation

Foreign Currency Translation — The Company revalues assets, liabilities, revenue and expense denominated in non-U.S. Dollars (“USD”) functional currencies into USD reporting currencies using applicable exchange rates. Gains and losses relating to nonfunctional currency transactions, including non-U.S. operations where the functional currency is USD, are reported on the Consolidated Statements of Income.

During the quarter ended September 30, 2015, the Company’s foreign subsidiary in China — East West Bank (China) Limited, changed its functional currency from USD to Renminbi (“RMB”). The assets and liabilities of this subsidiary are translated, for consolidation purposes, from RMB to USD reporting currency at period-end rates and generally at average rates for results of operations. Gains and losses arising from the translations are recorded in the Foreign currency translation adjustment account within AOCI in stockholders’ equity, along with any related hedged effects.

New Accounting Pronouncements Adopted and Recent Accounting Pronouncements

NEW ACCOUNTING PRONOUNCEMENTS ADOPTED

In February 2015, the FASB issued Accounting Standards Update (“ASU”) 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis that changes the analysis a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The amended guidance: 1) modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities; 2) eliminates the presumption that a general partner should consolidate a limited partnership; 3) affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and 4) provides a scope exception from the consolidation guidance for reporting entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a7 of the Investment Company Act of 1940 for registered money market funds. The Company adopted this amended guidance in the first quarter of 2016 and the adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

In April 2015, the FASB issued ASU 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 simplifies the presentation of debt issuance costs related to a recognized debt liability to be presented on the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The Company adopted this guidance retrospectively in the first quarter of 2016. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

In April 2015, the FASB issued ASU 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. ASU 2015-05 amends ASC 350-40 and requires the Company to determine whether a cloud computing arrangement contains a software license. If the arrangement contains a software license, the Company should account for the fees related to the software license element consistent with how the acquisitions of other software licenses are accounted for under ASC 350-40. If the arrangement does not contain a software license, the Company should account for the arrangement as a service contract. The Company adopted this guidance prospectively to all arrangements entered into or materially modified in the first quarter of 2016. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

In October 2016, the FASB issued ASU 2016-17, Consolidation (Topic 810):Interests Held through Related Parties That Are under Common Control to amend ASU 2015-02’s consolidation requirements that apply to a single decision maker’s evaluation of interests held through related parties that are under common control when it is determining whether it is the primary beneficiary of a VIE. ASU 2016-17 requires that the single decision maker considers its indirect economic interests in a VIE held through related parties that are under common control on a proportionate basis, in a manner consistent with its consideration of its indirect economic interests held through related parties that are not under common control. Entities that have adopted ASU 2015-02 are required to apply ASU 2016-17 retrospectively to all relevant prior periods beginning with the fiscal year in which ASU 2015-02 was initially applied. The Company adopted ASU 2016-17 retrospectively in the fourth quarter of 2016. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The new guidance replaced existing revenue recognition guidance for contracts to provide goods or services to customers.  ASU 2014-09 clarifies the principles for recognizing revenue and replaces nearly all existing revenue recognition guidance in U.S. GAAP. Quantitative and qualitative disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers are also required. ASU 2014-09 as amended by ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, is effective for interim and annual periods beginning after December 15, 2017 and is applied on either a modified retrospective or full retrospective basis. Early adoption is permitted for interim and annual periods beginning after December 15, 2016. The Company’s revenue is mainly comprised of net interest income from financial assets and liabilities, which is explicitly excluded from the scope of the new guidance, and noninterest income. The Company continues to evaluate the impact of ASU 2014-09 on our noninterest income and on our presentation and disclosures. The Company’s implementation efforts include the identification of revenue within the scope of ASU 2014-09 and the review is on-going.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 requires equity investments, except those accounted for under the equity method of accounting or consolidated, to be measured at fair value with changes recognized in net income. If there is no readily determinable fair value, the guidance allows entities the ability to measure investments at cost less impairment, whereby impairment is based on a qualitative assessment. The guidance eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value of financial instruments measured at amortized cost and changes the presentation of financial assets and financial liabilities on the Consolidated Balance Sheets or in the footnotes. If an entity has elected the fair value option to measure liabilities, the new accounting guidance requires the portion of the change in the fair value of a liability resulting from credit risk to be presented in other comprehensive income. The Company has not elected to measure any of its liabilities at fair value. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is not permitted except for certain specific changes under the fair value option guidance. To adopt the amendments, the Company is required to make a cumulative-effect adjustment to the consolidated balance sheet as of the beginning of the fiscal year in which the guidance is effective. However, the amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the adoption date. The Company is currently evaluating the impact on its Consolidated Financial Statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is intended to increase transparency and comparability in the accounting for lease transactions. ASU 2016-02 requires lessees to recognize all leases longer than twelve months on the Consolidated Balance Sheets as lease assets and lease liabilities and quantitative and qualitative disclosures regarding key information about leasing arrangements. Lessor accounting is largely unchanged. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years with an option to early adopt. The Company is currently evaluating the potential impact on its Consolidated Financial Statements. The Company expects a gross-up of its Consolidated Balance Sheets as a result of recognizing lease liabilities and right of use assets. The Company does not expect a material impact to its recognition of operating lease expense on its Consolidated Statements of Income.

In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships, to clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument in an existing hedging relationship would not be considered a termination of the derivative instrument or a change in a critical term of the hedging relationship provided that all other hedge accounting criteria in ASC 815 continue to be met. This clarification applies to both cash flow and fair value hedging relationships. ASU 2016-05 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years with an option to early adopt. The Company has an option to adopt the amendments of this ASU either on a prospective basis or modified retrospective basis. The adoption of this guidance will not have a material impact on the Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments that requires an entity to use a four step decision model when assessing contingent call (put) options that can accelerate the payment of principal on debt instruments to determine whether they are clearly and closely related to their debt hosts. ASU 2016-06 will be effective for interim and annual reporting periods beginning after December 15, 2016 and must be implemented using a modified retrospective basis. Early adoption is permitted. The adoption of this guidance will not have a material impact on the Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-07, Investments—Equity Method and Joint Ventures (Topic 323):Simplifying the Transition to the Equity Method of Accounting, to eliminate the requirement for an investor to retroactively apply the equity method when its increase in ownership interest (or degree of influence) in an investee triggers equity method accounting. The amendments in ASU 2016-07 also require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in AOCI at the date the investment becomes qualified for use of the equity method. ASU 2016-07 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years and should be applied prospectively. Early adoption is not permitted. The adoption of this guidance will not have a material impact on the Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, to simplify several aspects of the accounting for share-based payment transactions, including the accounting for income taxes, forfeitures, statutory tax withholding requirements, as well as classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The Company has adopted ASU 2016-09 in the first quarter of 2017 and has begun recording the excess tax benefits and deficiencies within the income tax expense on a prospective basis. The Company does not expect the adoption of this guidance to have a material impact on its Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments to introduce a new approach based on expected losses to estimate credit losses on certain types of financial instruments, which modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new “expected credit loss” impairment model will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, available-for-sale and held-to-maturity (“HTM”) debt securities, net investments in leases and off-balance-sheet credit exposures. For available-for-sale debt securities with unrealized losses, ASU 2016-13 does not change the measurement method of credit losses, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models and methods for estimating the allowance for loans and lease losses and requires disclosure of the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination (i.e., by vintage year). ASU 2016-13 is effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. Earlier adoption is permitted as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. While the Company is still evaluating the impact on its Consolidated Financial Statements, the Company expects that ASU 2016-13 may result in an increase in the allowance for credit losses due to the following factors: 1) the allowance for credit losses will increase to provide for expected credit losses over the remaining expected life of the loan portfolio, and will consider expected future changes in macroeconomic conditions; 2) the nonaccretable difference on the PCI loans will be recognized as an allowance, offset by an increase in the carrying value of the PCI loans; and 3) an allowance may be established for estimated credit losses on available-for-sale and HTM debt securities. The amount of increase will be impacted by the portfolio composition and quality, as well as the economic conditions and forecasts as of the adoption date. The Company has began its implementation efforts by identifying key interpretive issues, and assessing its processes and identifying the system requirements against the new guidance to determine what modifications may be required.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, to provide guidance on the classification of certain cash receipts and payments on the consolidated statement of cash flows in order to reduce diversity in practice. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of this guidance to have a material impact on its Consolidated Financial Statements.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, whichrequires the Company to include in its cash and cash-equivalent balances in the statement of cash flows those amounts that are deemed to be restricted cash and restricted cash equivalents. In addition, the Company is required to explain the changes in the combined total of restricted and unrestricted balances in the statement of cash flows. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, where the guidance should be applied using a retrospective transition method to each period presented. Early adoption is permitted. The Company is currently evaluating the impact on its Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment to simplify the accounting for goodwill impairments. An entity will no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. ASU 2017-04 also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. ASU 2017-04 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years and should be applied prospectively. Early adoption is permitted for interim or annual goodwill impairment tests with measurement dates after January 1, 2017. The Company is currently evaluating the impact on its Consolidated Financial Statements.
