	NOTE 1—SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES
	OPERATIONS SUMMARY
	East West Bancorp, Inc. (referred to herein on an unconsolidated basis as “East West” and on a consolidated basis as the “Company” or “we”) is a registered bank holding company that offers a full range of banking services to individuals and small to mid-size 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. The Bank operates 94 banking locations throughout California, six branches in New York, four branches in Georgia, two branches in Massachusetts, one branch in Nevada, one branch in Texas, and four branches in Washington. In Greater China, the Bank’s presence includes three full-service branches in Hong Kong, in Shanghai, and in Shantou. The Bank also has three representative offices in China located in Beijing, Guangzhou and Shenzhen and one in Taipei, Taiwan.
	The Bank focuses on commercial lending, including commercial real estate loans, commercial business loans and trade finance loans. The Bank also provides financing for residential loans including single-family and multifamily loans. To a lesser extent, the Bank also makes construction development and consumer loans. Included in the Bank’s locations are twelve in-store branches located in 99 Ranch Market stores in Southern and Northern California. The Bank’s revenues are derived from providing financing for residential and commercial real estate and business customers, as well as investing activities. Funding for lending and investing activities is obtained through acceptance of customer deposits, Federal Home Loan Bank advances and other borrowing activities.
	SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation — The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America and general practices within the banking industry. The following is a summary of significant principles used in the preparation of the accompanying financial statements. In preparing the financial statements, management of the Company has made a number of estimates and assumptions pertaining to the reporting of assets and liabilities, including the fair value of assets acquired and liabilities assumed, the FDIC indemnification asset, valuation of OREO, the allowance for loan losses, the disclosure of contingent assets and liabilities and the disclosure of income and expenses for the periods presented in conformity with accounting principles generally accepted in the United States of America. Actual results could differ from those estimates.
	Principles of Consolidation — The consolidated financial statements include the accounts of East West Bancorp, Inc., 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”). In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, the Trusts are not consolidated into the accounts of East West Bancorp, Inc.
	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, may require us to make a number of significant judgments. Based on the observability of the inputs used in the valuation techniques, we classify our 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. In determining the fair value of financial instruments, we use market prices of the same or similar instruments whenever such prices are available. We do 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 analyses. These modeling techniques incorporate our 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.
	Securities Purchased Under Resale Agreements (“Resale Agreements”) — The Company purchases securities under resale agreements with terms that range from one day to several years. These agreements are collateralized by mortgage-backed securities and mortgage or commercial loans that are generally held by a third party custodian. The purchases are over-collateralized to ensure against unfavorable market price movements. In the event that the fair value of the securities decreases below the carrying amount of the related repurchase agreement, the counterparty is required to deliver an equivalent value of additional securities. The counterparties to these agreements are nationally recognized investment banking firms that meet credit eligibility criteria and with whom a master repurchase agreement has been duly executed. Resale agreements that are short-term in nature, or have terms of up to 90 days, are included in cash and cash equivalents. Resale agreements with terms greater than 90 days are separately categorized.
	Investment Securities — The Company classifies its investment securities according to their purpose and holding period. Investment securities available-for-sale are reported at estimated fair value, with unrealized gains and losses excluded from operations and reported as a separate component of accumulated other comprehensive income or loss, net of tax, in stockholders’ equity.
	The fair values of the investment securities are generally determined by independent external pricing service providers who have experience in valuing these securities and by comparison to and/or average of quoted market prices obtained from independent external brokers. In obtaining such valuation information from third parties, the Company has evaluated the methodologies used to develop the resulting fair values. The Company performs a monthly analysis on the broker quotes and the third party pricing service quotes to ensure that the prices represent a reasonable estimate of the fair value. The procedures include, but are not limited to, initial and ongoing review of third party pricing methodologies, review of pricing trends, and monitoring of trading volumes. The Company considers whether prices received from independent brokers represent a reasonable estimate of fair value through the use of observable market inputs including comparable trades, the yield curve, spreads and, when available, market indices. As a result of this analysis, if the Company determines there is a more appropriate fair value based upon the available market data, the price received from the third party is adjusted accordingly. 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 that include observable market based inputs. Additionally, the majority of these independent broker quotations are non-binding.
	The Company applies a modified valuation approach to certain investment securities for which it believes the current broker prices obtained are based on forced liquidation or distressed sale values in inactive markets. The fair value of each of these securities is individually determined based on a combination of the market approach, reflecting current broker prices, and the income approach, which is a discounted cash flow approach. In calculating the fair value derived from the income approach, the Company makes assumptions related to the implied rate of return, general change in market rates, estimated changes in credit quality and liquidity risk premium, specific non-performance and default experience in the collateral underlying the security; additionally, broker discount rates are taken into consideration in determining the discount rate. The values resulting from each approach (i.e. market and income approaches) are weighted to derive the final fair value of each security trading in an inactive market.
	Amortization of premiums and accretion of discounts on securities are recorded as yield adjustments on such securities using the effective interest method. The specific identification method is used for purposes of determining cost in computing realized gains and losses on investment securities sold.
	At each reporting date, the Company assesses whether there is an “other-than-temporary” impairment (“OTTI”) in its portfolio of investment securities. If we determine that a decline in fair value is other-than-temporary, an impairment loss is recognized in current earnings. When we have the intent and ability to hold debt securities and it is not more likely than not that we will be required to sell these securities with OTTI for a period necessary to recover the noncredit-related impairment losses, only the credit-related impairment losses are recognized in current earnings. In these instances, the noncredit-related impairment losses are charged to other comprehensive income. The Company examines all individual securities that are in an unrealized loss position at each reporting date for other-than-temporary impairment. Specific investment level factors that are examined to assess impairment include the nature of the investments, the severity and duration of the loss, the probability that the Company will be unable to collect all amounts due, an analysis of the issuers of the securities and whether there has been any cause for default on the securities, and any change in the rating of the securities by the various rating agencies. Additionally, management takes into consideration the Company’s financial resources as well as the Company’s overall ability and intent to hold the securities and not be required to sell the securities until their fair values recover.
	The Company considers all available information relevant to the collectability of the security, including information about past events, current conditions, and reasonable and supportable forecasts, when developing the estimate of future cash flows and making its other-than-temporary impairment assessment for its portfolio of trust preferred securities. The Company considers factors such as remaining payment terms of the security, prepayment speeds, expected defaults, the financial condition of the issuer(s), and the value of any underlying collateral.
	Loans Receivable — 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 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. Discounts or premiums on purchased loans are accreted or amortized to interest income using the effective interest method over the remaining period to contractual maturity adjusted for anticipated prepayments. Interest on loans is calculated using the simple-interest method on daily balances of the principal amounts outstanding. Accrual of interest is discontinued on a loan 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. Generally, loans are placed on nonaccrual status when they become 90 days past due. When interest accrual is discontinued, all unpaid accrued interest is reversed against interest income. In general, subsequent payments received are applied to the outstanding principal balance of the loan. 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.
	Loans held for sale are carried at the lower of aggregate cost or fair value using the aggregate method. 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 the computation of the gain or loss from the sale of the related loans. A valuation allowance is established if the fair value of such loans is lower than their cost, with a corresponding charge to noninterest income.
	Troubled Debt Restructurings (“TDR”) — A loan is identified as a troubled debt restructure when a borrower is experiencing financial difficulties and for economic or legal reasons related to these difficulties the Company grants a concession to the borrower in the restructuring that it would not otherwise consider. The Company has granted a concession when, as a result of the restructuring to a troubled borrower, it does not expect to collect all amounts due, including principal and/or interest accrued at the original terms of the loan. 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, or a note split with principal forgiveness. A restructuring executed at an interest rate that is at market interest rates is not a TDR. All troubled debt restructurings are reviewed for impairment. For modifications where we forgive principal, the entire amount of such principal forgiveness is immediately charged off. Generally, a nonaccrual loan that is restructured remains on nonaccrual status for a period of six months to demonstrate that the borrower can perform under the restructured terms. However, the borrower’s performance prior to the restructuring, or other significant events at the time of restructuring may be considered in assessing whether the borrower can meet the new terms and may result in the loan remaining on accrual status or being returned to accrual status after a shorter performance period. If the borrower’s performance under the new terms is not reasonably assured, the loan remains classified as a nonaccrual loan. Loans classified as TDRs are reported as impaired loans.
	Allowance for Loan Losses — The allowance for loan losses is established as management’s estimate of probable losses inherent in the loan portfolio. The allowance is increased by the provision for loan losses and decreased by charge-offs when management believes the uncollectability of a loan is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based on management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral and prevailing economic conditions. This 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.
	A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all scheduled payments of principal or interest due according to the 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 delay, 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. Impairment is measured on a loan-by-loan basis for residential, commercial real estate, and commercial and industrial loans based on the loan’s observable market price or the fair value of the collateral, less costs to sell, if the loan is collateral dependent, or the present value of expected future cash flows discounted at the loan’s effective interest rate. If the measure of the impaired loan is less than the recorded investment in the loan and the loan is classified as nonperforming and uncollectible, the deficiency is charged off against the allowance for loan losses. In general, consumer loans consist of homogeneous smaller balance loans and are collectively evaluated for impairment.
	Acquired Loans — Acquired loans are valued as of acquisition date in accordance with ASC 805. Loans purchased with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are accounted for under ASC 310-30.
	Under ASC 805 and 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. In situations where loans have similar risk characteristics, loans are 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 loan or pool are estimated using an internal cash flow model that projects cash flows and calculates the carrying value of the loan or pool, book yield, effective interest income and impairment, if any, based on loan or pool level events, respectively. Assumptions as to default rates, loss severity, loss curves and prepayment speeds are utilized to calculate the expected cash flows.
	At acquisition, the excess of the cash flows expected to be collected over the recorded investment is considered to be the accretable yield and is recognized as interest income over the life of the loan or pool. The excess of the contractual cash flows over the cash flows expected to be collected is considered to be the nonaccretable difference. Subsequent to the acquisition date, any increases in expected cash flows over those expected 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 those expected at purchase date that are probable are recognized by recording an allowance 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.
	Covered Loans — Loans acquired in an FDIC-assisted acquisition that are subject to an FDIC shared-loss agreement are referred to as covered loans. Covered loans are reported exclusive of the expected cash flow reimbursements we expect to collect from the FDIC. All covered loans are accounted for under ASC 805 and ASC 310-30.
	FDIC Indemnification Asset — In conjunction with the FDIC-assisted acquisitions of Washington First International Bank and United Commercial Bank, the Bank entered into shared-loss agreements with the FDIC related to covered loans and covered other real estate owned (see “Covered Other Real Estate Owned” below). The FDIC indemnification asset is initially recorded at fair value, based on the discounted value of expected future cash flows under the shared-loss agreement. The Company has elected to account for amounts receivable under the shared-loss agreements as an indemnification asset in accordance with ASC 805. The difference between the present value and the undiscounted cash flows the Company expects to collect from the FDIC is accreted into noninterest income over the life of the FDIC indemnification asset. The FDIC indemnification asset is reviewed quarterly and adjusted for any changes in expected cash flows based on recent performance and expectations for future performance of the covered portfolio. These adjustments are measured on the same basis as the related covered loans and covered other real estate owned. Any increases in cash flow of the covered loans over those expected will reduce the FDIC indemnification asset and any decreases in cash flow of the covered loans over those expected will increase the FDIC indemnification asset. Over the life of the FDIC indemnification asset, increases and decreases are recorded as adjustments to noninterest income. During the year, the bank lowered the credit discount on the UCB covered loan portfolio as the credit quality was performing better than originally estimated. By lowering the credit discount, interest income will increase over the life of the loans. Correspondingly, with the lowered credit discount, the expected reimbursement from the FDIC under the loss sharing agreement will decrease, resulting in amortization of the FDIC indemnification asset which is recorded as a charge to noninterest income.
	Other Real Estate Owned — Other real estate owned (“OREO”) represents properties acquired through foreclosure or through full or partial satisfaction of loans, is considered held for sale, and is recorded at the lower of cost or estimated fair value at the time of foreclosure. Loan balances in excess of the fair value of the real estate acquired at the date of foreclosure are charged against the allowance for loan losses. After foreclosure, the real estate is carried at the lower of carrying value or fair value less costs to sell. Subsequent declines in the fair value of OREO below the carrying value are recorded through the use of a valuation allowance by charges to noninterest expense. Any subsequent operating expenses or income of such properties are also charged to noninterest expense. If the OREO is sold within three months of foreclosure, the Company substitutes the value received in the sale (net of costs to sell) for the fair value (less costs to sell). Any adjustment made to the loss originally recognized at the time of foreclosure is then charged against or credited to the allowance for loan losses, if deemed material. Otherwise, any declines in value, after foreclosure, are recorded in non-interest expense as gains or losses from the sale or disposition of the real estate. Gain recognition upon disposition of a property is dependent on the sale having met certain criteria relating to the buyer’s initial investment in the property sold.
	Covered Other Real Estate Owned — All other real estate owned acquired in an FDIC-assisted acquisition that are subject to an FDIC shared-loss agreement are referred to as covered other real estate owned. Covered other real estate owned is reported exclusive of the expected cash flow reimbursements we expect to collect from the FDIC. Upon transferring covered loan collateral to covered other real estate owned status, acquisition date fair value discounts on the related loan are also transferred to covered other real estate owned. Fair value adjustments on covered other real estate owned result in a reduction of the covered other real estate carrying amount through expense and a corresponding increase of the FDIC reimbursement for 80% of the adjustment resulting in income.  The net of that expense and income is the non-reimbursed portion or 20% of the estimated loss to the Bank which is the net amount charged against earnings.
	Investment in Affordable Housing Partnerships — The Company owns limited partnership interests in projects of affordable housing for lower income tenants. The investments in which the Company has a limited partnership interest that exceeds 5% are recorded using the equity method of accounting. The remaining investments are recorded using the cost method and are being amortized over the life of the related tax credits. The tax credits are being recognized in 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 — The Company has goodwill, which represents the excess of the purchase price over the fair value of net assets acquired, as a result of 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. Premiums on deposits, 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 premiums on deposits is recognized by writing down the asset to the extent that the carrying value exceeds the estimated fair value.
	Investment in Federal Home Loan Bank Stock — As a member of the Federal Home Loan Bank (“FHLB”) of San Francisco, the Bank is required to own common stock in the FHLB of San Francisco based upon our balance of residential mortgage loans and outstanding FHLB advances. As a result of the acquisition of WFIB in 2010, the Bank also owns common stock in the FHLB of Seattle. FHLB stock is carried at cost and may be sold back to the FHLB at its carrying value. Cash dividends are accrued and reported as dividend income.
	Investment in Federal Reserve Bank Stock — As a member of the Federal Reserve Bank (“FRB”) of San Francisco, the Bank is required to maintain stock in the FRB of San Francisco based on a specified ratio relative to our capital. FRB stock is carried at cost and may be sold back to the FRB at its carrying value. Cash dividends are accrued and reported as dividend income.
	Premises and Equipment — 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 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 circumstances indicate that the carrying amount of these assets may not be recoverable. An asset is considered impaired when the expected undiscounted cash flows over the remaining useful life is less than the net book value. When impairment is indicated for an asset, the amount of impairment loss is the excess of the net book value over its fair value.
	Securities Sold Under Repurchase Agreements (“Repurchase Agreements”) — The Company sells securities under repurchase agreements. These transactions are accounted for as collateralized financing transactions and recorded at the amounts at which the securities were sold. The Company may have to provide additional collateral to the counterparty, as necessary.
	Long-Term Debt — Long-term debt consists of junior subordinated debt and other long-term debt. The Company has six statutory business trusts whereby the Company is the owner of all the beneficial interests represented by the common securities of the Trusts, and third parties hold the fixed and variable rate capital 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. However, these securities will be phased out of the Tier I capital beginning in 2013, fully phased out by 2016.
	The Trusts are not consolidated by the Company. Junior subordinated debt represents liabilities of the Company to the Trusts and is included in long-term debt on the accompanying consolidated balance sheets.
	Federal Funds Purchased — The Company utilizes federal funds purchased as part of its short-term financing strategy. Federal funds purchased are generally overnight borrowings and mature within one business day to six months from the transaction date.
	Income Taxes — Deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each year-end, based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income.
	The Company examines its 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. The Company recognizes interest and penalties related to tax positions as part of its provision for income taxes.
	Stock-Based Compensation — The Company issues stock-based compensation to certain employees, officers, and directors and accounts for stock options using the fair value method, which generally results in compensation expense recognition.
	Transfers and Servicing of Financial Assets and Extinguishments of Liabilities — Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company; (2) the transferee has the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets; and (3) the Company does not maintain effective control over the transferred assets through either (a) an agreement that entitles and obligates the Company to repurchase or redeem them before their maturity or (b) an agreement that provides the Company with both the unilateral ability to cause the holder to return specific assets and a more than trivial benefit attributable to that ability. The difference between the net proceeds received and the carrying amount of the financial assets being sold is recognized as a gain or loss on sale.
	Earnings Per Share (“EPS”) — The Company applies the two-class method of computing EPS. Under the two-class method, EPS is determined for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. The Company’s restricted stock, which receive dividends as declared, qualify as participating securities. Restricted stock units issued by the Company are not considered participating securities, as they do not have dividend distribution rights during the vesting period. Diluted EPS is calculated on the basis of the weighted average number of shares outstanding during the period plus potential dilutive shares.
	Comprehensive Income — The term “comprehensive income” describes the total of all components of comprehensive income, including net income and other comprehensive income. “Other comprehensive income” refers to revenues, expenses, and gains and losses that are included in comprehensive income but are excluded from net income because they have been recorded directly in equity under the provisions of other Financial Accounting Standards Board statements. In accordance with the adoption of ASU 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income, the Company presents comprehensive income in the consolidated statements of comprehensive income, which was formerly presented in the consolidated statements of changes in stockholders’ equity.
	Derivative Financial Instruments — 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. All derivative instruments, including certain derivative instruments embedded in other contracts, are recognized on the consolidated balance sheet at fair value with the change in fair value reported in earnings. When master netting agreements exist, the Company nets counterparty positions with any cash collateral received or delivered.
	The Company’s interest rate swaps on certain certificates of deposit qualify for hedge accounting treatment under ASC 815, Derivatives and Hedging. The Company documents its hedge relationships, 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. This includes designating the derivative contract as a “fair value hedge” which is a hedge of a recognized asset or liability. All derivatives designated as fair value hedges are linked to specific hedged items or to groups of specific assets and liabilities on the balance sheet. Both at inception and quarterly thereafter, the Company assesses whether the derivatives used in hedging transactions are highly effective (as defined in the guidance) in offsetting changes in the fair value of the hedged item. Retroactive effectiveness is also assessed as well as the continued expectation that the hedge will remain effective prospectively. Any ineffective portion of the changes of fair value hedges is recognized immediately in interest expense in the consolidated statements of income.
	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 derivative instrument is terminated or the hedge designation removed, the previous adjustments to the carrying amount of the hedged liability would be subsequently accounted for in the same manner as other components of the carrying amount of that liability. For interest-bearing liabilities, such adjustments would be amortized into earnings over the remaining life of the respective liability.
	The Company also offers various derivative products to clients and enters into derivative transactions in due course. These transactions are not linked to specific Company assets or liabilities in 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 each reporting period with changes in fair value recorded in the consolidated statements of income.
	Reclassifications — Certain items in the consolidated balance sheet and the consolidated statements of income for the years ended December 31, 2012 and 2011 were reclassified to conform to the 2013 and 2012 presentation, respectively. These reclassifications did not affect previously reported net income.
	RECENT ACCOUNTING STANDARDS
	In October 2012, the FASB issued ASU 2012-06, Business Combinations (Topic 805): Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution. ASU 2012-06 clarifies the applicable guidance for subsequently measuring an indemnification asset recognized as a result of a government-assisted acquisition of a financial institution. The standard instructs that when a reporting entity recognizes an indemnification asset, it should subsequently account for the change in the measurement of the indemnification asset on the same basis as the change in the assets subject to indemnification. Any amortization of changes in value should be limited to the contractual term of the indemnification agreement. The amended guidance is effective for interim and annual periods beginning on or after December 15, 2012. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements, as the Company had applied this methodology prior to the issuance of this ASU.
	In January 2013, the FASB issued ASU 2013-01, Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. ASU 2013-01 clarifies that the scope of ASU 2011-01 applies to derivatives, repurchase agreements, and securities lending transactions to the extent that they are (1) offset in the financial statements or (2) subject to an enforceable master netting arrangement or similar agreement. The amended guidance is effective for interim and annual periods beginning on or after January 1, 2013. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements. The Company did include additional disclosure in the notes to the consolidated financial statements to comply with the requirements of the ASU.
	In February 2013, the FASB issued ASU 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-02 enhances the reporting of reclassifications out of accumulated other comprehensive income by requiring entities to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under GAAP to be reclassified in its entirety to net income. For other amounts that are not required under GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under GAAP that provide additional detail about those amounts. The amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. The amendments are effective for interim and annual periods beginning on or after December 15, 2012. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements. The Company did include additional disclosure in the notes to the consolidated financial statements to comply with the requirements of the ASU.
	In July 2013, the FASB issued ASU 2013-10, Derivatives and Hedging (Topic 815): Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes. ASU 2013-10 permits the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) to be used as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815, in addition to interest rates on direct Treasury obligations of the U.S. government and the London Interbank Offered Rate (“LIBOR”). ASU 2013-10 is effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements.
	In January 2014, the FASB issues ASU 2014-01, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. ASU 2014-10 permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). ASU 2014-10 is effective for interim and annual periods beginning after December 15, 2014 and if elected, should be applied retrospectively to all periods presented. Early adoption is permitted. The Company is currently evaluating the impact on the Company’s consolidated financial statements.

FAIR VALUE	'
FAIR VALUE	'
	NOTE 2—FAIR VALUE
	Fair value is defined as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date. 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 inputs. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observability of the inputs used in the valuation techniques, the Company is required to provide the following information according to the fair value hierarchy noted below. The hierarchy is based on the quality and reliability of the information used to determine fair values. The hierarchy gives the highest priority to quoted prices available in active markets and the lowest priority to data lacking transparency. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:
	•                  Level 1 – Quoted prices for identical instruments that are highly liquid, observable and actively traded in over-the-counter markets. Level 1 financial instruments typically include U.S. Treasury securities.
	•                  Level 2 – 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 2 financial instruments typically include U.S. Government debt and agency mortgage-backed securities, municipal securities, corporate debt securities, single issuer trust preferred securities, foreign exchange options and interest rate swaps.
	•                  Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value is not solely based on observable market inputs and requires management judgment or estimation. This category typically includes pooled trust preferred securities, impaired loans, other real estate owned (“OREO”) and derivatives payable.
	The Company records investment securities available-for-sale, derivative liabilities, foreign exchange options, interest rate swaps and short-term foreign exchange contracts at fair value on a recurring basis. Certain other assets such as impaired loans, other real estate owned, loans held for sale, goodwill, premiums on acquired deposits and other investments are recorded at fair value on a nonrecurring basis. Nonrecurring fair value measurements typically involve assets that are periodically evaluated for impairment and for which any impairment is recorded in the period in which the remeasurement is performed.
	In determining the appropriate hierarchy levels, the Company performs a detailed analysis of assets and liabilities that are subject to fair value disclosure. The following tables present both financial and nonfinancial assets and liabilities that are measured at fair value on a recurring and nonrecurring basis. These assets and liabilities are reported on the consolidated balance sheets at their fair values as of December 31, 2013 and 2012. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. For assets measured on a recurring basis, there were no transfers in and out of Levels 1 and 3 or Levels 2 and 3 during 2013 and 2012.

Valuation Methodologies
Investment Securities Available-for-Sale — The fair values of the investment securities are generally determined by independent external pricing service providers who have experience in valuing these securities and by comparison to and/or average of 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 Company’s Level 3 available-for-sale securities include four pooled trust preferred securities. The fair values of these investment securities represent less than 1% of the total available-for-sale investment securities. The fair values of the pooled trust preferred securities have traditionally been based on the average of at least two quoted market prices obtained from independent external brokers since broker quotes in an active market are given the highest priority. As a result of the continued illiquidity in the pooled trust preferred securities market, it is the Company’s view that current broker prices (which are typically non-binding) on certain pooled trust preferred securities are based on forced liquidation or distressed sale values in very inactive markets that are not representative of the fair value of these securities. As such, the Company considered what weight, if any, to place on transactions that are not orderly when estimating fair value.
For the pooled trust preferred securities, the fair value was derived based on discounted cash flow analyses (the income method) prepared by management. In order to determine the appropriate discount rate used in calculating fair values derived from the income method for the pooled trust preferred securities, the Company has made assumptions using an exit price approach related to the implied rate of return which have been adjusted for general changes in market rates, estimated changes in credit risk and liquidity risk premium, specific nonperformance, and default experience in the collateral underlying the securities. Significant increases (decreases) in any of those inputs in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for the probability of default is accompanied by a directionally similar change in the assumption used for credit risk and liquidity risk. The actual Level 3 unobservable assumption rates used as of December 31, 2013 include: a constant prepayment rate of 0% for year 1-5 and 1% thereafter, a constant default rate of 1.2% for year 1-5 and 0.75% thereafter, and a recovery assumption of 0% for existing deferrals/defaults and 15% for future deferrals with a recovery lag of 60 months. Losses arising during the period, if any, are recognized in noninterest income.
Derivative Liabilities — The Company’s derivative liabilities include derivatives payable that fall within Level 3 and all other derivative liabilities which fall within Level 2. The derivatives payable are recorded in conjunction with certain certificates of deposit (“host instrument”). These CDs pay interest based on changes in the Chinese currency Renminbi (“RMB”), and are included in interest-bearing deposits on the consolidated balance sheets. The fair value of these embedded derivatives is based on the income approach. The payable is divided by the portion under FDIC insurance coverage and the non-insured portion. For the FDIC insured portion the Company applied a risk premium comparable to an agency security risk premium. For the non-insured portion, the Company considered its own credit risk in determining the valuation by applying a risk premium based on our institutional credit rating, which resulted in an adjustment of $1.6 million to the valuation of the derivative liabilities for the year ended December 31, 2013. Significant increases (decreases), if any, of those inputs in isolation would result in a significantly lower (higher) fair value measurement. The valuation of the derivatives payable falls within Level 3 of the fair value hierarchy since the significant inputs used in deriving the fair value of these derivative contracts are not directly observable. The actual Level 3 unobservable input used as of December 31, 2013 was a credit risk adjustment with a range of 0.68% to 0.73%. The Level 2 derivative liabilities are mostly comprised of the offsetting interest rate swaps with other counterparties. Refer to “Interest Rate Swaps” within this footnote for complete discussion.
Foreign Exchange Options — The Company has entered into foreign exchange option contracts with major investment firms. The settlement amount is determined based upon the performance of the Chinese currency RMB relative to the U.S. Dollar (“USD”) over the 5-year term of the contract. The performance amount is computed based on the average quarterly value of the RMB per the USD as compared to the initial value. The fair value of the derivative contract is provided by third parties and is determined based on the change in the RMB and the volatility of the option over the life of the agreement. The option value is derived based on the volatility of the option, interest rate, currency rate and time remaining to maturity. The Company’s consideration of the counterparty’s credit risk resulted in a nominal adjustment to the valuation of the foreign exchange options for the year ended December 31, 2013. The valuation of the option contract falls within Level 2 of the fair value hierarchy due to the observable nature of the inputs used in deriving the fair value of this derivative contract.
Interest Rate Swaps — The Company has entered into pay-fixed, receive-variable swap contracts with institutional counterparties to hedge against interest rate swap products offered to bank customers. This product allows borrowers to lock in attractive intermediate and long-term interest rates by entering into a pay-fixed, receive-variable swap contract with the Company, resulting in the customer obtaining a synthetic fixed rate loan. The Company has also entered into pay-variable, receive-fixed 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 the interest rate swap contracts is based on a discounted cash flow approach. The Company’s consideration of the counterparty’s credit risk resulted in a $272 thousand adjustment to the valuation of the interest rate swaps for the year ended December 31, 2013. The valuation of the interest rate swap falls within Level 2 of the fair value hierarchy due to the observable nature of the inputs used in deriving the fair value of this derivative contract.
Foreign Exchange Contracts — The Company entered 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 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 does not assume any foreign exchange rate risk as the contract with the customer and the contract with the institutional party mirror each other. The fair value is determined at each reporting period based on the change in the foreign exchange rate. Given the short-term nature of the contracts, the counterparties’ credit risks are considered nominal and resulted in no adjustments to the valuation of the short-term foreign exchange contracts for the year ended December 31, 2013. The valuation of the contract falls within Level 2 of the fair value hierarchy due to the observable nature of the inputs used in deriving the fair value of this derivative contract.
The Company also entered into long-term foreign exchange contracts to purchase/sell foreign currencies at set rates in the future. The fair value is determined at each reporting period based on the change in the foreign exchange rate. The Company’s consideration of the counterparty’s credit risk resulted in a nominal adjustment to the valuation of the long-term foreign exchange contract for the year ended December 31, 2013. The valuation of the contract falls within Level 2 of the fair value hierarchy due to the observable nature of the inputs used in deriving the fair value of this derivative contract.
Impaired Loans — We evaluate loan impairment according to the provisions of ASC 310-10-35, Receivables-Overall-Subsequent Measurement. Under ASC 310-10-35, loans are considered impaired when it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement, including scheduled interest payments. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as an expedient, at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent, less costs to sell. If the measure of the impaired loan is less than the recorded investment in the loan and the loan is classified as nonperforming and uncollectible, the deficiency is charged-off against the allowance for loan losses. Also, in accordance with ASC 310-10-35, loans that are considered impaired are specifically excluded from the quarterly migration analysis when determining the amount of the general valuation allowance for loan losses required for the period.
The Company’s impaired loans are generally measured using the fair value of the underlying collateral, which is determined based on the most recent valuation information received. Appraisals are obtained from third party appraisers and reviewed by management. Similarly, evaluations are obtained from third-parties or prepared internally and are also reviewed by management. Updated appraisals and evaluations are obtained on a regular basis or as necessary. Further, on a quarterly basis, all appraisals and evaluations of nonperforming assets are reviewed to assess the current carrying value and to ensure that the current carrying value is appropriate. In calculating the discount to be applied to an appraisal or evaluation, if necessary, the Company considers the location of collateral, the property type, and third party comparable sales. If it is assessed by management that the current value is not appropriate, adjustments to the carrying value will be calculated and a charge-off or a specific valuation allowance may be recorded to reduce the loan to the appropriate adjusted carrying value. The fair values may be adjusted as needed based on factors such as the Company’s historical knowledge and changes in market conditions from the time of valuation. Impaired loans are classified as Level 3 assets in the fair value hierarchy.
Other Real Estate Owned — The Company’s OREO represents properties acquired through foreclosure or through full or partial satisfaction of loans receivable are recorded at estimated fair value less cost to sell at the time of foreclosure and at the lower of cost or estimated fair value less 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. These valuations are reviewed and approved by the Company’s appraisal department, credit review department, or OREO department. Updated appraisals and evaluations are obtained on a regular basis or at least annually. Further, on a quarterly basis, all appraisals and evaluations of nonperforming assets are reviewed to assess the current carrying value and to ensure that the current carrying value is appropriate. In calculating the discount to be applied to an appraisal or evaluation, if necessary, the Company considers the location of collateral, the property type, and third party comparable sales. If it is assessed by management that the current value is not appropriate, adjustments to the carrying value will be calculated and a charge-off may be taken to reduce the OREO to the appropriate adjusted carrying value. The fair values may be adjusted as needed based on factors such as the Company’s historical knowledge and changes in market conditions from the time of valuation. OREO properties are classified as Level 3 assets in the fair value hierarchy.
Loans Held for Sale — The Company’s loans held for sale are carried at the lower of cost or fair value. These loans are currently comprised of mostly student loans. For these loans, the fair value of loans held for sale is derived from current market prices and comparative current sales. For the remainder of the loans held for sale, which fall within Level 2, the fair value is derived from third party sale analysis, existing sale agreements, or appraisal reports on the loans’ underlying collateral. As such, the Company records any fair value adjustments on a nonrecurring basis.

The methods and assumptions used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value are explained below:
Cash and Cash Equivalents — The carrying amounts approximate fair values due to the short-term nature of these instruments. Due to the short-term nature, the estimated fair value is considered to be within Level 1 of the fair value hierarchy.
Short-Term Investments — The fair values of short-term investments generally approximate their book values due to their short maturities. Due to the observable nature of the inputs used in deriving the estimated fair value of these instruments, the estimate is considered to be within Level 2 of the fair value hierarchy.
Securities Purchased Under Resale Agreements — Securities purchased under resale agreements with original maturities of 90 days or less are included in cash and cash equivalents. The fair value of securities purchased under resale agreements with original maturities of more than 90 days is estimated by discounting the cash flows based on expected maturities or repricing dates utilizing estimated market discount rates. Due to the observable nature of the inputs used in deriving the estimated fair value of these instruments, the estimate is considered to be within Level 2 of the fair value hierarchy.
Investment Securities Available-for-Sale — The fair values of the investment securities are generally determined by independent external pricing service providers who have experience in valuing these securities and by comparison to and/or average of 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. For pooled trust preferred securities, fair values are based on discounted cash flow analyses. Due to the unobservable inputs used within the discounted cash flow analysis, the estimate for pooled trust preferred securities is considered to be within Level 3 of the fair value hierarchy. The remainder of the portfolio is classified within Level 1 and Level 2, as discussed earlier in this footnote.
Loans Held for Sale — The fair value of loans held for sale is derived from current market prices and comparative current sales or from third party sale analysis, existing sale agreements, or appraisal reports on the loans’ underlying collateral, as applicable. Due to the observable nature of the inputs used in deriving the estimated fair value of these instruments, the estimate is considered to be within Level 2 of the fair value hierarchy.
Loans Receivable, net (includes covered and non-covered loans) — The fair value of loans is determined based on a discounted cash flow approach considered for an entry price value. The discount rate is derived from the associated yield curve plus spreads, and reflects the offering 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 valuation of credit for such loans. Due to the unobservable nature of the inputs used in deriving the estimated fair value of these instruments, the estimate is considered to be within Level 3 of the fair value hierarchy.
Investment in Federal Home Loan Bank Stock and Federal Reserve Bank Stock — The carrying amount approximates fair value, as the stock may be sold back to the Federal Home Loan Bank and the Federal Reserve Bank at carrying value. The valuation of these investments is considered to be within Level 2 of the fair value hierarchy, as the restrictions and value of the investments are the same for all financial institutions which are required to hold these investments.
Other Borrowings — The carrying amounts approximate fair values due to the short-term nature of these instruments, as such, due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are considered to be within Level 2 of the fair value hierarchy.
Accrued Interest Receivable — The carrying amounts approximate fair values due to the short-term nature of these instruments, as such, due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are considered to be within Level 2 of the fair value hierarchy.
Foreign Exchange Options — The fair value of the derivative contracts is provided by third parties and is determined based on the change in the RMB and the volatility of the option over the life of the agreement. The option value is derived based on the volatility of the option, interest rate, and time remaining to maturity. We also considered the counterparty’s credit risk in determining the fair value. Due to the observable nature of the inputs used in deriving the estimated fair value of these instruments, the estimate is considered to be within Level 2 of the fair value hierarchy.
Interest Rate Swaps — The fair value of the interest rate swap contracts is provided by a third party and is determined based on a discounted cash flow approach. The Company also considered the counterparty’s credit risk in determining the fair value. Due to the observable nature of the inputs used in deriving the estimated fair value of these instruments, the estimate is considered to be within Level 2 of the fair value hierarchy.
Foreign Exchange Contracts — The fair value of foreign exchange contracts is determined based on the change in foreign exchange rate. We also considered the counterparty’s credit risk in determining the fair value. Due to the observable nature of the inputs used in deriving the estimated fair value of these instruments, the estimate is considered to be within Level 2 of the fair value hierarchy.
Customer Deposit Accounts — The carrying amounts approximate  fair value for demand and interest checking deposits, savings deposits, and certain money market accounts as the amounts are payable on demand at the reporting date. Due to the observable nature of the inputs used in deriving the estimated fair value these instruments are considered to be within Level 2 of the fair value hierarchy. For time deposits, the cash flows are based on the contractual runoff and are discounted by the Bank’s current offering rates, plus spread. Due to the unobservable nature of the inputs used in deriving the estimated fair value of these instruments, the estimate is considered to be within Level 3 of the fair value hierarchy.
Federal Home Loan Bank 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 of these instruments, the estimate is considered to be within Level 2 of the fair value hierarchy.
Securities Sold Under Repurchase Agreements — For securities sold under repurchase agreements with original maturities of 90 days or less, the carrying amounts approximate fair values due to the short-term nature of these instruments. Most of the securities sold under repurchase agreements are long-term in nature and the fair values of securities sold under repurchase agreements are 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 of these instruments, the estimate is considered to be within Level 2 of the fair value hierarchy.
Accrued Interest Payable — The carrying amounts approximate fair values due to the short-term nature of these instruments, as such, due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are considered to be within Level 2 of the fair value hierarchy.
Long-Term Debt — The fair values of long-term debt are estimated by discounting the cash flows through maturity based on current market rates the Bank would pay for new issuances. Due to the observable nature of the inputs used in deriving the estimated fair value of these instruments, the estimate is considered to be within Level 2 of the fair value hierarchy.
Derivatives Liabilities — The Company’s derivative liabilities include “derivatives payable” and all other derivative liabilities. The Company’s derivatives payable are recorded in conjunction with certain certificates of deposit (“host instrument”). These CDs pay interest based on changes in RMB. The fair value of derivatives payable is estimated using the income approach. Additionally, we considered our own credit risk in determining the valuation. The other derivative liabilities are mostly comprised of the off-setting interest rate swaps. The fair value of the interest rate swap contracts is provided by a third party and is determined based on a discounted cash flow approach. The Company also considered the counterparty’s credit risk in determining the fair value. Due to the observable nature of the inputs used in deriving the estimated fair value of the interest rate swaps within derivative liabilities, the estimate is considered to be within Level 2 of the fair value hierarchy. Due to the unobservable nature of the inputs used in deriving the estimated fair value of derivatives payable within derivative liabilities, this estimate is considered to be within Level 3 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 we are 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.

	(1)                                        For 2013, the Company did not record any OTTI. For 2012, the Company recorded $99 thousand, on a pre-tax basis, of the credit portion of OTTI through earnings and $5.1 million of the non-credit portion of OTTI for pooled trust preferred securities in other comprehensive income.
	The Company did not have any investment securities held-to-maturity as of December 31, 2013 and 2012.
	The fair values of the investment securities are generally determined by independent external pricing service providers who have experience in valuing these securities and by comparison to and/or average of quoted market prices obtained from independent external brokers. The Company performs a monthly analysis on the pricing service quotes and the broker quotes received from third parties to ensure that the prices represent a reasonable estimate of fair value. The procedures include, but are not limited to, initial and ongoing review of third party pricing methodologies, review of pricing trends, and monitoring of trading volumes. The Company assesses whether the prices received from independent brokers represent a reasonable estimate of fair value through the use of observable market inputs including comparable trades, the yield curve, spreads and, when available, market indices. As a result of this analysis, if the Company determines there is a more appropriate fair value based upon available market data, the price received from third parties is adjusted accordingly.
	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 that utilize inputs that may be difficult to corroborate with observable market based data. Additionally, the majority of these independent broker quotations are non-binding.
	As a result of the ongoing financial crisis in the U.S. and global markets, the market for the pooled trust preferred securities has been distressed since mid-2007. It is the Company’s view that current broker prices (which are typically non-binding) on these securities are based on forced liquidation or distressed sale values in very inactive markets that are not representative of the fair value of these securities. As such, the Company considered what weight, if any, to place on transactions that are not orderly when estimating fair value. For the pooled trust preferred securities the Company determined their fair values using the methodologies set forth in Note 2 to the Company’s consolidated financial statements presented elsewhere in this report.
	The following table shows the Company’s rollforward of the amount related to OTTI credit losses for the years ended December 31, 2013 and 2012:

	For the year ended December 31, 2013, the Company recorded $13.9 million of gross gains and $1.8 million of gross losses resulting in a net income statement impact of $12.1 million of gain on sale of investment securities. As compared to December 31, 2012, the Company recorded $28.2 million of gross gains and $27.4 million of gross losses resulting in a net income statement impact of $757 thousand of gain on sale of investment securities. For the year ended December 31, 2011, the Company recorded $18.1 million of gross gains and $8.4 million of gross losses resulting in a net income statement impact of $9.7 million of gain on sale of investment securities. The tax expense on the sale of investment securities available-for-sale amounted to $5.1 million, $318 thousand and $4.1 million for the years ended December 31, 2013, 2012 and 2011, respectively.

Unrealized Losses
The majority of the unrealized losses related to securities that have been in a continuous loss position for less than twelve months are related to agency, municipal and residential agency mortgage-backed securities. As of December 31, 2013, the Company had $394.3 million in agency securities, $281.0 million in municipal securities and $885.2 million in residential agency mortgage-backed securities, representing approximately 14%, 10% and 32% of the total investment securities available-for-sale portfolio, respectively.
As of December 31, 2013, there were 65 individual securities that have been in a continuous unrealized loss position for twelve months or more. The majority of the $19.7 million unrealized losses were composed of 32 municipal securities with unrealized losses of $6.8 million, 5 positions in trust preferred securities with unrealized losses of $5.6 million, and 21 residential agency mortgage-backed securities with unrealized losses of $4.4 million. The remaining 7 securities or $2.9 million in unrealized losses were comprised of investment grade corporate debt and commercial agency mortgage-backed securities.
As of December 31, 2013 there were also 239 securities, not including the 65 securities above, which have been in a continuous unrealized loss position for less than twelve months. The majority of the $45.2 million unrealized losses were composed of 16 agency securities with $12.7 million in unrealized losses, 94 municipal securities with $10.8 million in unrealized losses, and 55 residential agency mortgage-backed securities with $10.6 million unrealized losses. The remaining 74 securities or $11.1 million in unrealized losses were comprised of U.S. Treasury securities, commercial agency mortgage-backed securities, other residential mortgage-backed securities, investment grade corporate debt and other securities. These securities have fluctuated in value since their purchase dates as market interest rates have fluctuated and as long-term rates increased. The Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell the investments before recovery of their current amortized cost basis. As such, the Company does not deem these securities, to be other-than-temporarily impaired as of December 31, 2013.
As of December 31, 2012, there were 13 individual securities that have been in a continuous unrealized loss position for twelve months or more. These securities are comprised of 5 positions in trust preferred securities with a total fair value of $12.6 million and 8 investment grade debt securities with a fair value of $182.7 million. As of December 31, 2012 there were also 77 securities, not including the 13 securities above, which have been in a continuous unrealized loss position for less than twelve months. The securities in an unrealized loss position for less than twelve months include 26 residential agency mortgage-backed securities, 29 municipal securities, 11 investment grade corporate debt securities, 9 U.S. Treasury securities, 1 government agency security, and 1 commercial mortgage-backed security. The unrealized losses on these securities are primarily attributed to the market impact to the sovereign debt crisis in Europe.  The company does not have direct holdings of European sovereign debt. However, the Company is indirectly affected through the overall impact to the market and especially to corporate debt securities pricing.  The issuers of these securities have not, to our 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 does not intend to sell these securities and it is not more likely than not that the Company will be required to sell the investments before recovery of their current amortized cost basis. As such, the Company does not deem these securities, other than those previously stated, to be other-than-temporarily impaired as of December 31, 2012.
Corporate Debt Securities
As of December 31, 2013, the majority of the unrealized losses related to securities that have been in a continuous loss position of twelve months or longer are due to 5 positions in trust preferred debt securities, 32 municipal securities and 21 residential agency mortgage-backed securities. As of December 31, 2013, these trust preferred securities had an estimated fair value of $14.4 million, representing approximately 1% of the total investment securities available-for-sale portfolio. As of December 31, 2013, these non-investment grade debt instruments had gross unrealized losses amounting to $5.6 million, or 28% of the total amortized cost basis of these securities. We did not record an impairment loss on our portfolio of pooled trust preferred securities during 2013.
During 2012 and 2011, the Company recorded $99 thousand  and $633 thousand, respectively, in noncredit-related impairment losses on the five positions in trust preferred securities due to rating downgrades caused by increases in market spreads, concerns regarding the housing market and lack of liquidity in the market.
Investment Securities Maturities
The scheduled maturities of investment securities at December 31, 2013 are presented as follows:
	Amortized			Estimated
	Cost			Fair Value
	(In thousands)
Due within one year	$	417,774		$	401,970
Due after one year through five years	547,189			542,293
Due after five years through ten years	750,811			732,404
Due after ten years	1,070,716			1,057,130
Total investment securities available-for-sale	$	2,786,490		$	2,733,797
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.
At December 31, 2013 and 2012, investment securities available-for-sale with a par value of $1.97 billion and $1.78 billion, respectively, were pledged to secure public deposits, FHLB advances, repurchase agreements, Federal Reserve Bank’s discount window, or for other purposes required or permitted by law.

	The following table summarizes the fair value and balance sheet classification of derivative instruments as of December 31, 2013 and 2012. The notional amount of the contract is not recorded on the consolidated balance sheets, but is used as the basis for determining the amount of interest payments to be exchanged between the counterparties. If the counterparty fails to perform, the Company’s counterparty credit risk is equal to the amount reported as a derivative asset. The valuation methodology of derivative instruments is disclosed in Note 2 to the Company’s consolidated financial statements presented elsewhere in this report.

	Derivatives Designated as Hedging Instruments
	Interest Rate Swaps on Certificates of Deposit — The Company is exposed to changes in the fair value of certain of its fixed rate certificates of deposit due to changes in the benchmark interest rate, LIBOR. In 2013, the Company entered into three receive-fixed, pay-variable interest rate swaps and two receive-fixed pay-variable interest rate swap steepeners, with major brokerage firms, with a total notional amount of $85.0 million. The interest rate swaps were entered into as a fair value hedge of three fixed rate certificates of deposit and two fixed/variable certificate of deposit, for a total amount of $85.0 million. During 2012, the Company entered into two receive-fixed, pay-variable interest rate swaps with a total notional amount of $50.0 million. The interest rate swaps were entered into, with major brokerage firms, as a fair value hedge of two fixed rate certificates of deposit, for a total amount of $50.0 million. The interest rate swaps and the associated certificates of deposits have the same maturity dates. 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.
	As of December 31, 2013 and 2012 the total notional amount of the interest rate swaps on the certificates of deposit was $135.0 million and $50.0 million, respectively. The fair value of the interest rate swaps amounted to a $16.9 million and $1.5 million liability, respectively, as of December 31, 2013 and 2012. During the year ended December 31, 2013 and 2012, the Company recognized a net reduction of $632 thousand and $3.6 million, respectively, in expense related to hedge ineffectiveness. The Company also recognized a net reduction to interest expense of $2.1 million and $3.7 million, for the years ended December 31, 2013 and 2012, respectively, related to net settlements on the derivatives.
	Derivatives Not Designated as Hedging Instruments
	Equity Swap Agreements — In December 2007, the Company entered into two equity swap agreements with a major investment brokerage firm to economically hedge against market fluctuations in a promotional equity index certificate of deposit product offered to bank customers which has a term of 5 years and pays interest based on the performance of the HSCEI. Under ASC 815, a certificate of deposit that pays interest based on changes in an equity index is a hybrid instrument with an embedded derivative (i.e. equity call option) that must be accounted for separately from the host contract (i.e. the certificate of deposit). In accordance with ASC 815, both the embedded equity call options on the certificates of deposit and the freestanding equity swap agreements are marked-to-market each reporting period with resulting changes in fair value recorded in the consolidated statements of income. These equity swap agreements matured during 2012.
	Foreign Exchange Options — During 2010, the Company entered into foreign exchange option contracts with major brokerage firms to economically hedge against currency exchange rate fluctuations in a certificate of deposit product available to bank customers. This product, which has a term of 5 years, pays interest based on the performance of the Chinese currency Renminbi (“RMB”) relative to the U.S. Dollar. Under ASC 815, a certificate of deposit that pays interest based on changes in currency 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 marked-to-market each reporting period with resulting changes in fair value reported in the consolidated statements of income.
	As of December 31, 2013 and 2012 the notional amount of the foreign exchange options totaled $85.6 million. The fair values of the foreign exchange options and embedded derivative liability for these contracts amounted to a $6.3 million asset and a $3.7 million liability as of December 31, 2013. The fair values of the foreign exchange options and embedded derivative liability for these contracts amounted to a $5.0 million asset and a $3.1 million liability as of December 31, 2012. The Company did not deliver collateral, in the form of securities to counterparty institutions as of December 31, 2013. The Company delivered collateral, in the form of securities to counterparty institutions, valued at $940 thousand, for foreign exchange option contracts that were in a net liability position as of December 31, 2012.
	Interest Rate Swaps — During 2010, the Company entered into pay-fixed, receive-variable swap contracts with institutional counterparties to economically hedge against interest rate swap products offered to bank customers. This product allows borrowers to lock in attractive intermediate and long-term interest rates by entering into a pay-fixed, receive-variable swap contract with the Company, resulting in the customer obtaining a synthetic fixed rate loan. The Company does not assume any interest rate risk since the swap agreements mirror each other. As of December 31, 2013 the total notional amount of the interest rate swaps, including mirror transactions, with the institutional counterparties and the bank customers totaled $1.92 billion asset and $1.92 billion liability. In comparison, as of December 31, 2012, the total notional amount of the interest rate swaps, including mirror transactions, with the institutional counterparties and the bank customers totaled $1.19 billion asset and $1.19 billion liability. The interest rate swap agreements are marked-to-market each reporting period with resulting changes in fair value reported in the consolidated statements of income.
	The fair values of the interest rate swap contracts with the institutional counterparties and the bank customers amounted to a $28.1 million asset and a $26.4 million liability, as of December 31, 2013. The fair values of the interest rate swap contracts with the institutional counterparty and the bank customers amounted to a $36.9 million asset and a $36.8 million liability, as of December 31, 2012.
	Foreign Exchange Contracts — The Company enters into short-term forward foreign exchange contracts on a regular basis to economically hedge against foreign exchange rate fluctuations. As of December 31, 2013 and 2012 the notional amount of the short-term foreign exchange contracts totaled $426.0 million and $112.5 million, respectively. The fair values of the short-term foreign exchange contracts amounted to a $6.0 million asset and a $3.2 million liability, as of December 31, 2013. The fair values of the short-term foreign exchange contracts amounted to an $896 thousand asset and a $688 thousand liability, as of December 31, 2012. The gross aggregate value of the short-term foreign exchange contracts by counterparty was an asset of $1.5 million as of December 31, 2013 and an asset of $495 thousand as of December 31, 2012.
	The Company also entered into long-term foreign exchange contracts to purchase/sell foreign currencies at set rates in the future. As of December 31, 2013 the notional amount of the long-term foreign exchange contracts totaled $14.8 million. The fair values of the long-term foreign exchange contracts amounted to a $200 thousand asset and a $183 thousand liability, as of December 31, 2013.

	Credit Risk-Related Contingent Features — The Company has agreements with some of its derivative counterparties that contain a provision where if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations.
	The Company also has agreements with some of its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well/adequately capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. Similarly, the Company could be required to settle its obligations under certain of its agreements if the Company was issued a notice of prompt corrective action.
	Balance Sheet Offsetting — The Company has entered into agreements with all counterparty financial institutions, which include master netting agreements.  However, the Company elects to account for all derivatives with counterparty institutions on a gross basis, excluding the foreign exchange options which are not under agreements that include master netting terms. The Company has also entered into securities purchased under resale agreements (“resale agreements”), and securities sold under agreements to repurchase (“repurchase agreements”) which have master netting agreements that allow for the netting of collateral positions. These repurchase and resale agreements of securities are not eligible for offset in the consolidated balance sheet.
	The following tables show the gross derivatives, resale agreements and repurchase agreements in the consolidated balance sheets and for each the respective collateral received or pledged in the form of other financial instruments, which are generally marketable securities. 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. Most of the assets and liabilities in the following tables were transacted under master netting arrangements that contain a conditional right of offset, such as close-out netting, upon default. Collateral accepted or pledged in resale and repurchase agreements with other financial institutions also may be sold or re-pledged by the secured party, but is usually delivered to and held by third party trustees.
	The Company delivered collateral, in the form of securities to counterparty institutions, for derivatives that were in a net liability position as of December 31, 2013 and 2012 (refer to the table below). Under the Dodd-Frank legislation, as of June 10, 2013, the Company must clear all LIBOR interest rate swaps through a clearing house. As such the Company is required to pledge cash collateral for the margin. As of December 31, 2013 the Company posted $187 thousand of cash collateral. As of December 31, 2012, the Company did not receive or pledge cash collateral and there were no net asset positions with respect to collateral.

COVERED ASSETS AND FDIC INDEMNIFICATION ASSET	'
COVERED ASSETS AND FDIC INDEMNIFICATION ASSET	'
	NOTE 7— COVERED ASSETS AND FDIC INDEMNIFICATION ASSET
	Covered Assets
	Covered assets consist of loans receivable and OREO that were acquired in the WFIB Acquisition on June 11, 2010 and in the UCB Acquisition on November 6, 2009 for which the Company entered into shared-loss agreements with the FDIC. The shared-loss agreements covered over 99% of the loans originated by WFIB and all of the loans originated by UCB, excluding the loans originated by UCB in China under its United Commercial Bank China (Limited) subsidiary. The Company shares in the losses, which began with the first dollar of loss incurred, on covered assets under the shared-loss agreements.
	Pursuant to the terms of the shared-loss agreements, the FDIC is obligated to reimburse the Company 80% of eligible losses for both WFIB and UCB with respect to covered assets. For the UCB covered assets, the FDIC will reimburse the Company for 95% of eligible losses in excess of $2.05 billion. The Company has a corresponding obligation to reimburse the FDIC for 80% or 95%, as applicable, of eligible recoveries with respect to covered assets. The commercial loan shared-loss agreement and single-family residential mortgage loan shared-loss agreement are in effect for 5 years and 10 years, respectively, from the acquisition date and the loss recovery provisions of these agreements continue on and are in effect for 8 years and 10 years, respectively, from the acquisition date.
	The commercial loan shared-loss agreements related to the UCB and WFIB acquisitions will terminate on November 6, 2014 and June 11, 2015, respectively. The single-family residential mortgage loan shared-loss agreements carry expiration dates of November 6, 2019 and June 11, 2020 for UCB and WFIB, respectively. Upon the completion of these agreements, any losses on loans left in the portfolio will belong solely to the Company. However, due to the performance of the covered loan portfolio, the Company does not expect the expiration of these agreements to have a material impact.
	Forty-five days following the 10th anniversary of the respective acquisition date, the Company will be required to pay to the FDIC a calculated amount, based on the specific thresholds of losses not being reached. The calculation of this potential liability as stated in the shared-loss agreements is 50% of the excess, if any of (i) 20% of the Intrinsic Loss Estimate and (ii) the sum of (A) 25% of the asset discount plus (B) 25% of the Cumulative Shared-Loss Payments plus (C) the Cumulative Servicing Amount if net losses on covered loans subject to the stated threshold is not reached. As of December 31, 2013 and 2012, the Company’s recorded estimate in the balance sheet, for this liability to the FDIC for WFIB and UCB was $74.7 million and $27.7 million, respectively.
	At each date of acquisition, we accounted for the loan portfolio acquired from the respective bank at fair value. This represents the discounted value of the expected cash flows from the portfolio. In estimating the nonaccretable difference, we (a) calculated the contractual amount and timing of undiscounted principal and interest payments (the “undiscounted contractual cash flows”) and (b) estimated the amount and timing of undiscounted expected principal and interest payments (the “undiscounted expected cash flows”). In the determination of contractual cash flows and cash flows expected to be collected, we assume no prepayment on the ASC 310-30 nonaccrual loan pools as we do not anticipate any significant prepayments on credit impaired loans. For the ASC 310-30 accrual loans for single-family, multifamily and commercial real estate, we used a third party vendor to obtain prepayment speeds in order to be consistent with market participant’s information. The third party vendor is recognized in the mortgage-industry for the delivery of prepayment and default models for the secondary market to identify loan level prepayment, delinquency, default, and loss propensities. The prepayment rates for the construction, land, and commercial and consumer pools have historically been low and so we applied the prepayment assumptions of our current portfolio using our internal modeling. The difference between the undiscounted contractual cash flows and the undiscounted expected cash flows is the nonaccretable difference. The nonaccretable difference represents our estimate of the credit losses expected and was considered in determining the fair value of the loans as of the acquisition date. The amount by which the undiscounted expected cash flows exceed the estimated fair value (the “accretable yield”) is accreted into interest income over the life of the loans. The Company has elected to account for all covered loans acquired in FDIC-assisted acquisitions under ASC 310-30.
	The carrying amounts and the composition of the covered loans as of December 31, 2013 and 2012 are as follows:

	Allowance on covered loans	-7,745		-5,153
	Total covered loans, net	$	2,187,898	$	2,935,595
	Credit Quality Indicators—The covered loans acquired are and will continue to be subject to the Bank’s internal and external credit review and monitoring. The same credit quality indicators are reviewed for the covered portfolio as the non-covered portfolio, to enable the monitoring of the borrower’s credit and the likelihood of repayment.
	Loans are risk rated based on analysis of the current state of the borrower’s credit quality. The analysis of credit quality includes review of all sources of repayment, the borrower’s current financial and liquidity status and all other relevant information. The Company utilizes an eight grade risk rating system, where a higher grade represents a higher level of credit risk. The eight grade risk rating system can be generally classified by the following categories: Pass or Watch, Special Mention, Substandard, Doubtful and Loss. The risk ratings reflect the relative strength of the sources of repayment. Refer to Note 8 for full discussion of risk ratings.
	The Company reduced the nonaccretable difference due to the performance of the portfolio and expectation for the inherent losses in the portfolio subsequent to the initial valuations. By lowering the nonaccretable discount, the overall accretable yield will increase thus increasing the interest income recognized over the remaining life of the loans. This reduction was primarily calculated based on the risk ratings of the loans.
	The Company acquired WFIB and UCB in 2010 and 2009, respectively. The majority of the covered loan portfolio accounted for under ASC 310-30, is still performing better than or as expected from the day one valuation. However, the Company has experienced some concentrated credit deterioration in certain loan pools. Thus, during 2013, due to the concentrated credit deterioration, within a few specific pools of loans, beyond the respective acquisition date fair value of these covered loans under ASC 310-30, a provision for credit losses was recorded through earnings. As of December 31, 2013, there was an allowance of $2.2 million for these loans under ASC 310-30 due to credit deterioration, which resulted from a provision of $2.2 million for the year ended December 31, 2013. This $2.2 million in allowance is allocated mainly to the portfolio’s commercial real estate segment.
	As of the acquisition date, WFIB’s and UCB’s loan portfolios included unfunded commitments for commercial lines of credit, construction draws and other lending activity. The total commitment outstanding as of the acquisition date is covered under the shared-loss agreements. However, any additional advances on these loans subsequent to acquisition date are not accounted for under ASC 310-30. Included in the following credit quality table are $320.2 million and $431.7 million of additional advances under the shared-loss agreements which are not accounted for under ASC 310-30 for the years ended December 31, 2013, and 2012, respectively. The Bank has considered these additional advances on commitments covered under the shared-loss agreements in the allowance for loan losses calculation. At December 31, 2013, these additional advances are within our loan segments as follows: $230.6 million of commercial and industrial loans, $46.7 million of commercial real estate loans, $30.9 million of consumer loans and $12.0 million of residential loans. In comparison, at December 31, 2012, these additional advances were within our loan segments as follows: $302.3 million of commercial and industrial loans, $83.4 million of commercial real estate loans, $34.5 million of consumer loans and $11.5 million of residential loans.
	During the year ended December 31, 2013, the Company recorded $1.4 million of charge-offs on covered loans outside of the scope of ASC 310-30. In comparison, during the year ended December 31, 2012, the Company recorded $6.5 million of charge-offs on covered loans outside of the scope of ASC 310-30. The provision on covered loans outside the scope of ASC 310-30 for the years ended December 31, 2013, 2012 and 2011 was $1.8 million, $5.0 million and $2.4 million, respectively. Refer to Note 8 for additional discussion of these covered charge-offs. As of December 31, 2013, $5.5 million, or 2.2%, of the total allowance is allocated to these additional advances on loans covered under the shared-loss agreements. This $5.5 million in allowance is allocated within our loan segments as follows: $1.8 million for commercial real estate loans, $3.2 million for commercial and industrial loans, $341 thousand for consumer loans and $176 thousand for residential loans. In comparison, as of December 31, 2012, $5.2 million or 2.2%, of the total allowance was allocated within our loan segments as follows: $2.5 million for commercial real estate loans, $2.4 million for commercial and industrial loans, $194 thousand for consumer loans and $87 thousand for residential loans.  The $2.2 million in allowance for loans under ASC 310-30 discussed above and the $5.5 million in allowance for loans outside the scope of ASC 310-30 together comprise the total covered allowance of $7.7 million or 3.1% of total allowance as of December 31, 2013.

Credit Risk and Concentrations—At each respective acquisition date, the covered loans were grouped into pools of loans with similar characteristics and risk factors per ASC 310-30. The pools were first developed based on loan categories and performance status. As of December 31, 2013 UCB covered loans represent approximately 94% of total covered loans. For the UCB acquisition, the loans were further segregated among the former UCB domestic, Hong Kong, and China portfolios, representing the three general geographic regions. In addition, the Company evaluated the make-up of geographic regions within the construction, land, and multi-family loan portfolios and further segregated these pools into distressed and non-distressed regions based on our historical experience of real estate loans within the non-covered portfolio. As of the date of acquisition 64% of the UCB portfolio was located in California, 10% was located in Hong Kong and 11% was located in New York. This assessment was factored into the day one valuation and discount applied to the loans. As such, geographic concentration risk is considered in the covered loan discount.
At December 31, 2013 and 2012, $126.9 million and $204.3 million, respectively, of the ASC 310-30 credit impaired loans were considered to be nonaccrual loans in accordance with the contractual terms of the individual loans.

As of December 31, 2013, we had covered OREO properties with a combined aggregate carrying value of $21.4 million. Approximately 31% and 31% of the carrying value of covered OREO properties as of December 31, 2013 were located in California and Massachusetts, respectively. In comparison, as of December 31, 2012, we had covered OREO properties with an aggregate carrying value of $26.8 million. During 2013, 26 properties with an aggregate carrying value of $31.2 million were added through foreclosure. The carrying value at December 31, 2013 is net of adjustments on covered OREO of $2.4 million. During 2013, we sold 46 covered OREO properties for total proceeds of $38.9 million resulting in a total net gain on sale of $4.7 million.
Changes in the accretable yield for the covered loans for the years ended December 31, 2013 and 2012 is as follows:
	2013		2012
	(In thousands)
Balance at beginning of period	$	556,986	$	785,165
Additions	—		—
Accretion	-347,010		-382,132
Changes in expected cash flows	251,569		153,953
Balance at end of period	$	461,545	$	556,986
The excess of cash flows expected to be collected over the initial fair value of acquired loans is referred to as the accretable yield and is accreted into interest income over the estimated life of the acquired loans using the effective yield method. The accretable yield will change due to:
•                   estimate of the remaining life of acquired loans which may change the amount of future interest income;
•                   estimate of the amount of contractually required principal and interest payments over the estimated life that will not be collected (the nonaccretable difference); and
•                   indices for acquired loans with variable rates of interest.
During the year, the estimate of the amount of contractually required principal and interest payments over the estimated life that will not be collected (the nonaccretable difference) was reduced as the loss on certain loan pools was evaluated and determined to be lower than expected. As a result of the reduction in the nonaccretable yield, the accretable yield increased, as did the amortization of the FDIC indemnification asset. Consequently, $190.3 million was reclassified from non-accretable yield to accretable yield due to changes in loss rate assumptions during 2013. In comparison, $38.6 million was reclassified from non-accretable yield to accretable yield due to changes in loss rate assumptions during 2012. Due to the greater expected collectability on the remaining covered loans, the accrued liability to the FDIC also increased during 2013.
From December 31, 2012 to December 31, 2013, excluding scheduled principal payments, a total of $739.3 million of loans were removed from the covered loans accounted for under ASC 310-30 due to loans being paid in full, sold, transferred to covered OREO or charged-off. Interest income was adjusted by $168.1 million related to payoffs and removals offset by charge-offs.
From December 31, 2011 to December 31, 2012, excluding scheduled principal payments, a total of $924.7 million of loans were removed from the covered loans accounted for under ASC 310-30 due to loans being paid in full, sold, transferred to covered OREO or charged-off. Interest income was adjusted by $124.7 million related to payoffs and removals offset by charge-offs.
From December 31, 2010 to December 31, 2011, excluding scheduled principal payments, a total of $932.2 million of loans were removed from the covered loans accounted for under ASC 310-30 due to loans being paid in full, sold, transferred to covered OREO or charged-off. Interest income was adjusted by $102.1 million related to payoffs and removals offset by charge-offs.
FDIC Indemnification Asset
Due to reductions of the nonaccretable difference on the UCB covered loan portfolio, the expected reimbursement from the FDIC under the loss-sharing agreement decreased. As such, the Company is amortizing the difference between the recorded amount of the FDIC indemnification asset and the expected reimbursement from the FDIC over the life of the indemnification asset, in line with the improved accretable yield as discussed above. For the years ended December 31, 2013 and 2012, the Company recorded $99.1 million and $33.8 million, respectively, of amortization against non-interest income. For the years ended December 31, 2013 and 2012, the Company also recorded $95.5 million and $144.0 million, respectively, reduction to the FDIC indemnification asset resulting from paydowns, payoffs, loan sales, and charge-offs. Additionally, during 2013 and 2012, $47.0 million and $17.0 million, respectively, were recorded as the increase in the estimate of liability owed to the FDIC at the completion of the FDIC loss share agreements.
The table below shows FDIC indemnification asset activity for 2013 and 2012:
	2013		2012

Balance at end of period	$	74,708	$	316,313
(1)                                     Reductions relate to charge-offs, partial prepayments, loan payoffs and loan sales which result in a corresponding reduction of the indemnification asset.
(2)                                     This represents the change in the calculated estimate the Company will be required to pay the FDIC at the end of the FDIC loss share agreements, due to lower thresholds of losses.
FDIC Receivable
As of December 31, 2013, the FDIC loss sharing receivable was $30.3 million as compared to $73.1 million as of December 31, 2012. This receivable represents 80% of reimbursable amounts from the FDIC, under the FDIC loss-sharing agreements that have not yet been received. These reimbursable amounts include net charge-offs, loan-related expenses and OREO-related expenses. Consequently, 100% of the loan-related and OREO expenses are recorded as noninterest expense, 80% of any reimbursable expense is recorded as noninterest income, netting to the 20% of actual expense paid by the Company. The FDIC also shares in 80% of recoveries received. Thus, the FDIC receivable is reduced when we receive payment from the FDIC as well as when recoveries occur. The FDIC loss-sharing receivable is included in other assets on the consolidated balance sheet.

	Accrued interest on covered and non-covered loans receivable amounted to $94.5 million and $76.8 million at December 31, 2013 and 2012, respectively.
	At December 31, 2013 and 2012, covered and non-covered loans receivable totaling $10.57 billion and $8.88 billion, respectively, were pledged to secure borrowings from the FHLB and the Federal Reserve Bank.
	The Bank offers adjustable rate (“ARM”) first mortgage loans secured by one-to-four unit residential properties located in its primary lending areas. The Bank originated $1.62 billion and $735.3 million in new residential single-family loans during 2013 and 2012, respectively.
	The Bank also offers ARM residential multifamily loan programs. For the years ended December 31, 2013 and 2012, the Bank originated $247.1 million and $128.4 million, respectively, in multifamily residential loans. The Bank primarily offers ARM multifamily loan programs that have six-month, three-year, or five-year initial fixed periods and ARM single-family loan programs that have one-year or three-year initial fixed periods. The Bank originates single-family residential loans where the underwriting criteria are heavily based on a maximum loan to value ratio (generally of 60%) and no or limited verification or documentation of the borrower’s assets is obtained. The Bank considers all of the single-family and multifamily loans originated to be prime loans and the underwriting criteria include maximum loan-to-value ratios and minimum debt coverage ratios, as applicable. The Bank has single-family loans with interest-only features which represents approximately less than 1% of total single-family loans at both December 31, 2013 and December 31, 2012. Additionally, the Bank owns residential loans that were purchased several years ago that permit different repayment options. For these loans, there is the potential for negative amortization if the borrower so chooses. These residential loans that permit different repayment options represent approximately less than 1% of total residential loans at both December 31, 2013 and December 31, 2012. None of these loans were negatively amortizing as of December 31, 2013 and December 31, 2012.
	In addition to residential lending, the Bank’s lending activities also include commercial real estate, commercial and industrial, and consumer lending.  Our CRE lending activities include loans to finance income-producing properties and also construction and land loans.  Our C&I lending activities include commercial business financing for small and middle-market businesses in a wide spectrum of industries.  Included in commercial business loans are loans for working capital, accounts receivable lines, inventory lines, small business administration loans and lease financing.  We also offer a variety of international trade finance services and products, including letters of credit, revolving lines of credit, import loans, bankers’ acceptances, working capital lines, domestic purchase financing and pre-export financing. Consumer loans are primarily comprised of fully guaranteed student loans, home equity lines of credit, auto loans and the new insurance premium financing loans.
	All of the loans that the Bank originates are subject to its underwriting guidelines and loan origination standards. Management believes that the Bank’s underwriting criteria and procedures adequately consider the unique risks which may come from these products. The Bank conducts a variety of quality control procedures and periodic audits to ensure compliance with its origination standards, including criteria for lending and legal requirements.
	Credit Risk and Concentrations—The Company has a concentration of real estate loans in California. As of December 31, 2013, the Company had $4.59 billion in non-covered commercial real estate loans and $4.19 billion in non-covered residential loans, of which approximately 86% are secured by real properties located in California. Deterioration in the real estate market generally including residential and commercial real estate could result in additional loan charge-offs and provisions for loan losses in the future, which could have a material adverse effect on the Company’s financial condition, net income and capital. In addition, although most of the Company’s trade finance loans relate to trade with Asian countries, the majority of our loans are made to companies domiciled in the United States. A substantial portion of this business involves California based customers engaged in import activities as well as some export activities. We also offer export-import financing to various domestic and foreign customers. Certain trade finance loans may be guaranteed by the Export-Import Bank of the United States or the Export-Import Bank of China.
	Purchased Loans—During 2013, the Company purchased loans with an unpaid principal balance of $776.7 million and a carrying amount of $759.3 million. 63% of the purchased loans during the period are student loans, which are mostly guaranteed by the U.S. Department of Education and pose limited credit risk. 36% of the purchased loans are insurance premium financing loans, which are included in the commercial and consumer loan portfolios, as applicable. The remaining 1% are other loans.
	Loans Held for Sale—Loans held for sale totaled $205.0 million and $174.3 million as of December 31, 2013 and 2012, respectively. Loans held for sale are recorded at the lower of cost or fair value. Fair value, if lower than cost, is determined based on valuations obtained from market participants or the value of the underlying collateral. As of December 31, 2013, all of these loans were student loans, which are mostly guaranteed by the U.S. Department of Education. During 2013, in total, loans receivable of $97.1 million were reclassified to loans held for sale. Some of these loans were purchased by the Company with the intent to be held for investment; however, subsequent to their purchase, the Company’s intent for these loans changed and they were consequently reclassified to loans held for sale. The remainder of loans were immediately classified as loans held for sale. Proceeds from sales of loans held for sale were $117.3 million in 2013, resulting in net gains on sale of $4.0 million. In comparison, proceeds from sales of loans held for sale were $351.9 million and $652.7 million in 2012 and 2011, respectively, resulting in net gains on sale of $14.6 million and $14.5 million, respectively.
	Credit Quality Indicators—Loans are risk rated based on analysis of the current state of the borrower’s credit quality. The analysis of credit quality includes review of all sources of repayment, the borrower’s current payment performance/delinquency, the borrower’s 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. However, the risk ratings remain the overall credit quality indicator for the Company as well as the credit quality indicator utilized for estimating the appropriate allowance for loan losses. The Company utilizes an eight grade risk rating system, where a higher grade represents a higher level of credit risk. The eight grade risk rating system can be generally classified by the following categories: Pass or Watch, Special Mention, Substandard, Doubtful and Loss. The risk ratings reflect the relative strength of the sources of repayment.
	Pass or 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 risk that requires monitoring, but full repayment is expected. Special Mention loans are considered to have potential weaknesses that warrant closer attention by management. Special Mention is considered a transitory grade. If any 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 is presented that indicates 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 due to changes in borrower status and likelihood of loan repayment. The tables below present the non-covered loan portfolio by credit quality indicator as of December 31, 2013 and 2012. As of December 31, 2013, non-covered loans graded Substandard have decreased by $29.3 million, or 6% from December 31, 2012. There were no Doubtful or Loss grade loans as of December 31, 2013 and 2012.

Generally, loans 90 or more days past due are placed on nonaccrual status, at which point interest accrual is discontinued and all unpaid accrued interest is reversed against interest income. Additionally, loans that are not 90 or more days past due but have identified deficiencies, including delinquent TDR loans, are also placed on nonaccrual status. Nonaccrual loans totaled $111.7 million and $108.1 million at December 31, 2013 and 2012, respectively. Loans not 90 or more days past due totaled $40.5 million and $27.2 million as of December 31, 2013 and 2012, respectively, and were included in non-covered nonaccrual loans.

Troubled debt restructurings — A troubled debt restructuring (“TDR”) is a modification of the terms of a loan when the lender, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower. The concessions may be granted in various forms, including a below-market change in the stated interest rate, reduction in the loan balance or accrued interest, extension of the maturity date with a stated interest rate lower than the current market rate or note splits referred to as A/B notes. In A/B note restructurings, the original note is bifurcated into two notes where the A note represents the portion of the original loan which allows for acceptable loan-to-value and debt coverage on the collateral and is expected to be collected in full and 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 is comprised of the A note balances only. 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 Bank was willing to accept at the time of the restructuring for a new loan with comparable risk and the loan is not impaired based on the terms specified by the restructuring agreement.
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 met or exceeded the modified terms. For nonperforming restructured loans, the loan will remain on nonaccrual status until the borrower demonstrates a sustained period of performance, generally six consecutive months of payments. The Company had $71.8 million and $94.6 million in total performing restructured loans as of December 31, 2013 and 2012, respectively. Nonperforming restructured loans were $11.1 million and $10.0 million at December 31, 2013 and 2012, respectively. Included as TDRs were $4.3 million and $34.8 million of performing A/B notes as of December 31, 2013 and 2012, respectively.  All TDRs are included in the balance of impaired loans.

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 Bank’s recovery. As of December 31, 2013, modifications of residential TDRs, including single and multi-family loans, primarily included A/B note splits, which result in a partial charge-off or loss for the Bank at the modification date. Residential TDRs modified using A/B note splits totaled $1.1 million, as of December 31, 2013. Commercial real estate TDRs, including income producing, construction and land loans, were primarily modified through, A/B note splits, forbearance of payments and principal and/or interest deferment for a total of $17.5 million, as of December 31, 2013. As of December 31, 2013, modifications of commercial and industrial TDRs, including commercial business and trade finance loans, were restructured through extensions and principal and interest reduction with an impact of both a reduction of interest collected over the life of the loan and/or an extended time period for collection of principal and interest, for a total of $15.6 million as of December 31, 2013. Consumer TDRs, including student loans and other consumer loans, were restructured through maturity extensions, for a total of $639 thousand, as of December 31, 2013.
As of December 31, 2012, modifications of residential TDRs, including single and multi-family loans, primarily included principal and/or interest deferments, rate reductions, extensions, other principal adjustments and/or A/B note splits. A/B note splits result in a partial charge-off or loss for the bank at the modification date. Residential TDRs modified using principal and/or interest deferment and/or rate reductions totaled $12.7 million as of December 31, 2012. Residential TDRs modified using extensions, A/B note splits and/or other principal adjustments totaled $21.0 million as of December 31, 2012. Commercial real estate TDRs, including income producing, construction and land loans, were primarily modified through A/B note splits, principal reductions, extensions, and/or non-market interest rate changes with an impact of a partial charge-off or loss for the bank and reduction of interest collected over the life of the loan. Commercial real estate TDRs modified through A/B note splits, principal reductions, extensions and/or non-market interest changes totaled $9.2 million as of December 31, 2012. Commercial and industrial TDRs, including commercial business and trade finance loans, were restructured in various ways, including forbearance payments, principal reductions, principal and/or interest deferment and/or maturity extensions with an impact of both a reduction of interest collected over the life of the loan and/or an extended time period for collection of principal and interest, for a total of $5.0 million as of December 31, 2012. Consumer TDRs, including home equity lines of credit and other consumer loans, were restructured through principal deferments. Consumer TDRs modified through principal deferment totaled $108 thousand as of December 31, 2012.
Performing TDRs at December 31, 2013 were comprised of $17.4 million in residential loans, $37.6 million in commercial real estate loans, $16.7 million in commercial and industrial loans and $108 thousand in consumer loans. Nonperforming TDRs at December 31, 2013 were comprised of $3.6 million in residential loans, $3.4 million in commercial real estate loans, $3.5 million in commercial and industrial loans and $639 thousand in consumer loans.  In comparison, performing TDRs at December 31, 2012 were comprised of $43.5 million in residential loans, $47.4 million in commercial real estate loans, $3.6 million in commercial and industrial loans and $108 thousand in consumer loans. Nonperforming TDRs at December 31, 2012 were comprised of $5.1 million in residential loans, $1.9 million in commercial real estate loans and $3.0 million in commercial and industrial loans.
Subsequent to restructuring, a TDR that becomes delinquent, generally beyond 90 days is considered to have defaulted. The following table provides information for loans modified as TDRs within the previous 12 months that have subsequently defaulted as of December 31, 2013 and 2012 for the years ended December 31, 2013 and 2012, respectively.

All TDRs are included in the impaired loan quarterly valuation allowance process.  See the sections below Impaired Loans and Allowance for Loan Losses for the complete discussion. All portfolio segments of TDRs are reviewed for necessary specific reserves in the same manner as impaired loans of the same portfolio segment which have not been identified as TDRs. The modification of the terms of each TDR is considered in the current impairment analysis of the respective TDR. For all portfolio segments of delinquent TDRs, when the restructured loan is uncollectible and less than the recorded investment in the loan, 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 allowance, as appropriate. As of December 31, 2013 and 2012, the allowance for loan losses associated with TDRs was $13.0 million and $8.7 million for performing TDRs and $836 thousand and $203 thousand for nonperforming TDRs, respectively.
Impaired Loans — A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all scheduled payments of principal or interest due according to the original contractual terms of the loan agreement. Impaired loans include non-covered loans held for investment on nonaccrual status, regardless of the collateral coverage, and loans modified in a TDR.
The Bank’s loans are grouped into heterogeneous and homogeneous (mostly consumer loans) categories. Classified loans (graded Substandard or Doubtful) in the heterogeneous category are selected and evaluated for impairment on an individual basis. The Bank considers loans individually reviewed to be impaired if, based on current information and events, it is probable the Bank will not be able to collect all amounts due according to the original contractual terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as an expedient, 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 in the loan and the loan is classified as nonperforming and uncollectible, the deficiency is charged-off against the allowance for loan losses.
At December 31, 2013 and 2012, impaired non-covered loans totaled $183.5 million and $200.5 million, respectively. Impaired non-covered loans as of December 31, 2013 and 2012 are set forth in the following tables. The interest income recognized on impaired loans, excluding performing TDRs, is recognized on a cash basis when received.

(1)                                        Excludes interest from performing TDRs.

Allowance for Loan Losses
The allowance consists of specific reserves and a general reserve. The Bank’s loans fall into heterogeneous and homogeneous (mostly consumer loans) 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 reserve. The general reserve is calculated by utilizing both quantitative and qualitative factors. There are different qualitative risks for the loans in each portfolio segment. As of December 31, 2013, the Residential and CRE segments’ predominant risk characteristic is the collateral and the geographic location of the property collateralizing the loan. The risk is qualitatively assessed based on the change in the real estate market in those geographic areas. The C&I segment’s predominant risk characteristics are the global cash flows of the borrowers and guarantors, if any, and economic and market conditions. Consumer loans, excluding the student loan portfolio guaranteed by the U.S. Department of Education, are largely comprised of home equity lines of credit, for which the predominant risk characteristic is the real estate collateral securing the loan.
Our methodology to determine the overall appropriateness of the allowance is based on a classification migration model and qualitative considerations. The migration analysis examines pools of loans having similar characteristics and analyzes their loss rates over a historical period. We utilize historical loss factors derived from trends and losses associated with each pool over a specified period of time. Based on this process, we assign loss factors 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. As such, we utilize qualitative and environmental factors as adjusting mechanisms to supplement the historical results of the classification migration model. 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, and geographic concentrations. 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.
Covered Loans— The Company acquired UCB and WFIB in 2009 and 2010, respectively. The majority of the covered loan portfolio accounted for under ASC 310-30, is still performing better than or as expected from the day one valuation. However, the company has experienced some concentrated credit deterioration in certain pools. Thus, during 2013, due to the concentrated credit deterioration beyond the respective acquisition date fair value of these covered loans under ASC 310-30, a provision for credit losses has been recorded through earnings. As of December 31, 2013, there was an allowance of $2.2 million for these loans under ASC 310-30 due to credit deterioration, which resulted from a provision of $2.2 million for the year ended December 31, 2013. This $2.2 million of allowance for loan losses is allocated mainly to the portfolio’s commercial real estate segment.
As of the respective acquisition dates, WFIB’s and UCB’s loan portfolios included unfunded commitments for commercial lines of credit, construction draws and other lending activity. The total commitment outstanding as of the respective acquisition dates is covered under the shared-loss agreements. However, any additional advances on these loans subsequent to acquisition date are not accounted for under ASC 310-30. As additional advances on these commitments have occurred, the Bank has considered these amounts in the allowance for loan losses calculation. As of December 31, 2013 and 2012, $7.7 million, or 3.1%, and $5.2 million, or 2.2%, respectively, of the total allowance is allocated to the allowance for loan losses on covered loans. The covered loans acquired are, and will continue to be, subject to the Bank’s internal and external credit review and monitoring. The $2.2 million allowance for loans under ASC 310-30 discussed above and the $5.5 million in allowance for loans outside the scope of ASC 310-30 amount to $7.7 million or 3.1% of total allowance as of December 31, 2013.
During 2013, the Company recorded $1.4 million of charge-offs on covered loans outside of the scope of ASC 310-30 mainly in the commercial and industrial and commercial real estate loan segment. The resulting provision on covered loans for 2013 was $1.8 million. The charge-offs are within our loan segments as follows: $1.0 million of commercial and industrial loans and $380 thousand of commercial real estate loans. As these loans are covered under loss-sharing agreements with the FDIC, the Company recorded income of $1.1 million or 80% of the charge-off amount of $1.4 million in noninterest income as a net increase in the FDIC receivable, resulting in a net impact to earnings for the year of $287 thousand. In comparison, the Company recorded $6.5 million of charge-offs on several covered loans outside of the scope of ASC 310-30 during 2012. The resulting provision on covered loans for 2012 was $5.0 million. The charge-offs are within our loan segments as follows: $5.0 million of commercial and industrial loans and $1.5 million of commercial real estate loans. The $6.5 million of net charge-offs was mainly related to three specific covered loans. As these loans are covered under loss-sharing agreements with the FDIC, the Company recorded income of $5.2 million or 80% of the charge-off amount of $6.5 million in noninterest income as a net increase in the FDIC receivable, resulting in a net impact to earnings for the year of $1.3 million.
The Company recorded $22.4 million in total loan loss provisions during 2013, as compared to $65.2 million and $95.0 million during 2012 and 2011, respectively. When determined uncollectible, it is the Company’s policy to promptly charge-off the amount of impairment on a loan which represents the difference between the outstanding loan balance and the fair value of the collateral.  Recoveries are recorded when payment is received on loans that were previously charged-off through the allowance for loan losses. During 2013, the Company recorded $5.1 million in total net charge-offs in comparison to $48.7 million during 2012. The following table details activity in the allowance for loan losses, for both non-covered and covered loans, by portfolio segment for the year ended December 31, 2013 and 2012. 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.

Allowance for Unfunded Loan Commitments, Off-Balance Sheet Credit Exposures and Recourse Provisions—The allowance for unfunded loan commitments, off-balance sheet credit exposures and recourse provisions is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to these 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 to these same customers, and the terms and expiration dates of the unfunded credit facilities. As of December 31, 2013 and 2012, the allowance for unfunded loan commitments, off-balance sheet credit exposures, and recourse provisions amounted to $11.3 million and $9.4 million, respectively. The increase to this allowance during the year was reflective of additional reserve allocated for unfunded construction loan commitments. Net adjustments to the allowance for unfunded loan commitments, off-balance sheet credit exposures, and recourse provisions are included in the provision for loan losses.
Loans serviced for others amounted to $1.35 billion and $1.65 billion at December 31, 2013 and 2012, respectively. These represent loans that have either been sold or securitized for which the Bank continues to provide servicing and has limited recourse. The majority of these loans are residential and CRE at December 31, 2013 and 2012. Of the total allowance for unfunded loan commitments, off-balance sheet credit exposures and recourse provisions, $3.2 million and $4.8 million pertain to these loans as of December 31, 2013 and 2012, respectively. These loans are maintained off-balance sheet and are not included in the loans receivable balance.

	NOTE 10—AFFORDABLE HOUSING PARTNERSHIPS AND OTHER INVESTMENTS
	The Company invests in certain limited partnerships that are formed to develop and operate apartment complexes designed as high-quality affordable housing for lower income tenants throughout the United States. The Company’s ownership amount in each limited partnership varies. 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. The Company is not the primary beneficiary and, therefore, not required to consolidate these entities. Depending on the ownership percentage and the influence the Company has on the limited partnership, the Company uses either the equity method or cost method of accounting. If the partnerships cease to qualify during the compliance period, the credits may be denied for any period in which the projects are not in compliance and a portion of the credits previously taken may be subject to recapture with interest. The balance of the investments in these entities was $165.7 million and $185.6 million at December 31, 2013 and 2012, respectively.
		December 31,

	The Company also invests in certain limited partnerships that qualify for Community Reinvestment Act (CRA) credits or that qualify for other types of tax credits. The Community Reinvestment Act encourages banks to meet the credit needs of their communities for housing and other purposes, particularly in neighborhoods with low or moderate incomes. The balance of CRA and other investments was $69.2 million and $45.9 million at December 31, 2013 and 2012, respectively, and is included in other assets in the consolidated balance sheets.
	The Company finances the purchase of certain real estate tax credits generated by partnerships which own multiple properties currently under construction. These transactions were financed with non-recourse commitments which are collateralized by the Company’s partnership interests in the real estate investment tax credits. The Company’s unfunded commitments related to the affordable housing and other investments are payable on demand. Total unfunded commitments for these investments were $73.1 million and $84.6 million at December 31, 2013 and 2012, respectively, and are recorded in accrued expenses and other liabilities in the consolidated balance sheets.
	The Company’s usage of federal tax credits approximated $34.2 million, $18.7 million and $11.1 million during 2013, 2012 and 2011, respectively. The Company’s remaining tax credits approximated $165.7 million at December 31, 2013. Affordable housing and other investments amortization amounted to $27.3 million, $18.1 million and $17.3 million for the years ended December 31, 2013, 2012 and 2011, respectively. During 2013 and 2012, the Company had no impairment or sales of affordable housing and other investments.

	Goodwill
	The carrying amount of goodwill remained at $337.4 million as of December 31, 2013 and 2012. Goodwill is tested for impairment on an annual basis as of December 31, or more frequently as events occur, or as current circumstances and conditions warrant. The Company records impairment write-downs as charges to noninterest expense and adjustments to the carrying value of goodwill. Subsequent reversals of goodwill impairment are prohibited.
	As of December 31, 2013, the Company’s market capitalization based on total outstanding common shares was $4.81 billion and its total stockholders’ equity was $2.36 billion. The Company performed its annual impairment test as of December 31, 2013 to determine whether and to what extent, if any, recorded goodwill was impaired. The analysis compared the fair value of each of the reporting units, including goodwill, to the respective carrying amounts. If the carrying amount of the reporting unit, including goodwill exceeds the fair value of that reporting unit, then further testing for goodwill impairment is performed.
	The Company has identified three business divisions that meet the criteria of an operating segment in accordance with generally accepted accounting principles. The Company’s three operating segments are Retail Banking, Commercial Banking, and Other. The Company determined that there were no additional reporting units below each operating segment and therefore the reporting units are equivalent to the operating segments. For complete discussion and disclosure see Note 24 to the Company’s consolidated financial statements presented elsewhere in this report.
	In order to determine the fair value of the reporting units, a combined income and market approach was used. Under the income approach, the Company provided a net income projection for the next 3 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 is the cost savings that a purchaser of the reporting units could achieve by eliminating duplicative costs. Under the combined income and market approaches, the value from each approach was appropriately weighted to determine the fair value. As a result of this analysis, the Company determined that there was no goodwill impairment at December 31, 2013 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.
	The changes in the carrying amount of goodwill for the years ended December 31, 2013 and 2012 are summarized in the following table:
		As of December 31,
		2013		2012

	Premiums on Acquired Deposits
	The Company also has premiums on acquired deposits which 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. As of December 31, 2013 and 2012, the gross carrying amount of premiums on acquired deposits remained at $100.2 million, and the related accumulated amortization totaled $53.3 million and $43.9 million, respectively.
	The Company amortizes premiums on acquired deposits based on the projected useful lives of the related deposits. Amortization expense of premiums on acquired deposits was $9.4 million, $10.9 million and $12.3 million for the years ended December 31, 2013, 2012 and 2011, respectively. The Company did not record any impairment write-downs on deposit premiums during 2013, 2012 and 2011.

	Junior Subordinated Debt—As of December 31, 2013, the Company has six statutory business trusts for the purpose of issuing junior subordinated debt to third party investors. Junior subordinated debt is recorded as a component of long-term debt and includes the value of the common stock issued by the Trusts to the Company 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. Junior subordinated debt outstanding, issued by the Trusts to the Company, totaled $123.0 million at December 31, 2013, compared to $133.0 million at December 31, 2012. The junior subordinated debt of one statutory business trust was called during 2013 in order to reduce higher interest-bearing debt and the phase-out of trust preferred securities as Tier I regulatory capital. The related common stock outstanding, issued by the Trust to the Company amounted to $3.9 million and $4.2 million at December 31, 2013 and 2012, respectively.
	The proceeds from these issuances represent liabilities of the Company to the Trusts and are reported in the consolidated balance sheets as a component of long-term debt. Interest payments on these securities are made either quarterly or semi-annually and are deductible for tax purposes. Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, bank holding companies with more than $15 billion in total consolidated assets are no longer able to include trust preferred securities as Tier I regulatory capital which commenced in 2013 with phase-out complete by 2016. The junior subordinated debt is being phased out 25% each year, over the four year period, from Tier I capital into Tier II capital for regulatory purposes. This junior subordinated debt was issued in connection with our various pooled trust preferred securities offerings.
	The table below summarizes pertinent information related to outstanding junior subordinated debt issued by each Trust as of December 31, 2013 and 2012:

	The provision for income taxes was $130.8 million in 2013, representing an effective tax rate of 30.7%, compared to $143.9 million, representing an effective tax rate of 33.8% and $138.1 million, representing an effective tax rate of 36.0% for 2012 and 2011, respectively. Included in the income tax recognized during 2013 is $35.0 million in tax credits generated from our investments in affordable housing partnerships and other investments and other federal tax credits. In comparison, included in the income tax recognized during 2012 and 2011 are $18.7 million and $11.1 million, respectively, in tax credits generated from our investments in affordable housing partnerships and other investments.
	Management regularly reviews the Company’s tax positions and deferred tax assets. Factors considered in this analysis include future reversals of existing temporary differences, future taxable income exclusive of reversing differences, taxable income in prior carryback years, and tax planning strategies. The Company accounts for income taxes using the asset and liability approach, the objective of which is to establish deferred tax assets and liabilities for the temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities at enacted rates expected to be in effect when such amounts are realized and settled. Based on the available evidence, 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 loss carryforwards and certain foreign losses. Accordingly, a valuation allowance has been recorded for these amounts.
	As of December 31, 2013, the Company had a net deferred tax asset of $255.5 million.
	The provision for income taxes consists of the following components:

	Management believes that it is more likely than not that all of the deferred tax assets recorded at December 31, 2013 will be realized (except to the extent of the recorded valuation allowance) because it expects to have sufficient taxable income in future years to fully realize them. A valuation allowance has been provided for the state net operating losses (“NOLs”) (for states other than California, Georgia, Massachusetts and New York) since management believes that these NOLs may not be fully utilized. At December 31, 2013, the Bank had state net operating loss carryforwards of approximately $6.0 million.
	The following table summarizes the activity related to our unrecognized tax benefits:
		Year Ended December 31,

For the years ended December 31, 2013 and 2012, the Company increased the unrecognized tax benefits reserve by $1.2 million and $1.1 million, respectively, for the California enterprise zone net interest deduction. There were no reductions in unrecognized tax benefits for 2013. As of December 31, 2013 and 2012, the liability for uncertain tax positions was $6.3 million and $6.1 million, respectively. Also, for the years ended December 31, 2013 and 2012, the total amount of unrecognized tax benefits that, if recognized, would impact the effective tax rate is $3.0 million and $2.2 million, respectively.
During 2013, the Company closed the Internal Revenue Service (“IRS”) examination of the 2011 tax year with no material changes. In 2012, the Company executed a Memorandum of Understanding (“MOU”) with the IRS for the 2012 tax year to voluntarily participate in the IRS Compliance Assurance Process (“CAP”) where the IRS will assist the Company in identifying and resolving any tax issues that may arise throughout the 2012 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. The 2012 tax return filed in September 2013 received a full acceptance of all tax matters from the IRS.  The Company has entered a MOU with the IRS for the 2013 and 2014 tax years. For federal tax purposes, tax years from 2010 and beyond remain open. For California franchise tax purposes, tax years from 2003 and beyond remain open. The states of Alabama, Florida, New York, Ohio and Texas have initiated audits of East West Bank’s corporate income tax returns through the 2012 tax year. 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 during the year ending December 31, 2014.
The Company recognizes interest and penalties, if applicable, related to the underpayment of income taxes as a component of income tax expense in the consolidated statement of operations. The Company accrued interest and penalties of ($744) thousand, $1.2 million and $287 thousand for its unrecognized tax positions as of December 31, 2013, 2012 and 2011, respectively. Total interest and penalties accrued as of December 31, 2013 and 2012 were $1.6 million and $2.7 million, respectively.

COMMITMENTS AND CONTINGENCIES	'
COMMITMENTS AND CONTINGENCIES	'
	NOTE 19—COMMITMENTS AND CONTINGENCIES
	Credit Extensions—In the normal course of business, the Company has various outstanding commitments to extend credit that are not reflected in the accompanying 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 credit exposures.
	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. Because many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future funding requirements. As of December 31, 2013 and 2012, undisbursed loan commitments amounted to $4.02 billion and $2.61 billion, respectively. Substantially all commitments are for loans to be held for investment.
	Commercial letters of credit are issued to facilitate domestic and foreign trade transactions while standby letters of credit are issued to make payments on behalf of customers when certain specified future events occur. As of December 31, 2013 and 2012, commercial and standby letters of credit totaled $1.16 billion and $988.7 million, respectively. The Bank issues standby letters of credit (“SBLCs”) and financial guarantees to support the obligations of its customers to beneficiaries. Based on historical trends, the probability that it will have to make payments under standby letters of credit is low. Additionally, in many cases, the Bank holds collateral in various forms against these standby letters of credit. As part of its risk management activities, the Bank monitors the creditworthiness of the customer as well as its SBLC exposure; however, if the customer fails to perform the specified obligation to the beneficiary, the beneficiary may draw upon the standby letters of credit by presenting documents that are in compliance with the letter of credit terms. In that event, the Bank either repays the money borrowed or advanced, makes payment on account of the indebtedness of the customer or makes payment on account of the default by the customer in the performance of an obligation, to the beneficiary up to the full notional amount of the standby letters of credit. The customer is obligated to reimburse the Bank for any such payment. If the customer fails to pay, the Bank would, as applicable, liquidate collateral and/or set off accounts.
	Credit card lines are unsecured commitments that are not legally binding. Management reviews credit card lines at least annually and, upon evaluation of the customers’ creditworthiness, the Bank has the right to terminate or change certain terms of the credit card lines.
	The Bank uses the same credit policies in making commitments and conditional obligations as in extending loan facilities to customers. It evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, and income-producing commercial properties.
	As of December 31, 2013 and 2012, the allowance for unfunded loan commitments, off-balance sheet credit exposures, and recourse provision amounted to $11.3 million and $9.4 million, respectively. These amounts are included in accrued expenses and other liabilities in the accompanying consolidated balance sheets.
	Guarantees — From time to time, the Company sells or securitizes loans with recourse in the ordinary course of business. For loans that have been sold or securitized with recourse, the recourse component is considered a guarantee. When the Company sells or securitizes a loan with recourse, it commits to stand ready to perform if the loan defaults, and to make payments to remedy the default. As of December 31, 2013, total loans sold or securitized with recourse amounted to $338.8 million and were comprised of $42.2 million in single-family loans with full recourse and $296.6 million in multifamily loans with limited recourse. In comparison, total loans sold or securitized with recourse amounted to $461.8 million at December 31, 2012, comprised of $48.4 million in single-family loans with full recourse and $413.4 million in multifamily loans with limited recourse. In conjunction with the UCB Purchase and Assumption Agreement, East West Bank assumed all servicing agreements the prior UCB had entered into. The recourse provision on multifamily loans varies by loan sale and is limited to 4% of the top loss on the underlying loans. The Company’s recourse reserve related to loan sales and securitizations totaled $3.2 million and $4.8 million as of December 31, 2013 and 2012, respectively, and is included in accrued expenses and other liabilities in the accompanying consolidated balance sheets. The Company continues to experience minimal losses from the single-family and multifamily loan portfolios.
	The Company also sells or securitizes loans without recourse that may have to be subsequently repurchased if a defect that occurred during the loan origination process results in a violation of a representation or warranty made in connection with the securitization or sale of the loan. When a loan sold or securitized to an investor without recourse fails to perform according to its contractual terms, the investor will typically review the loan file to determine whether defects in the origination process occurred and if such defects give rise to a violation of a representation or warranty made to the investor in connection with the sale or securitization. If such a defect is identified, the Company may be required to either repurchase the loan or indemnify the investor for losses sustained. If there are no such defects, the Company has no commitment to repurchase the loan. As of December 31, 2013 and 2012, the amount of loans sold without recourse totaled $818.2 million and $953.2 million, respectively. Total loans securitized without recourse amounted to $193.8 million and $235.8 million, respectively, at December 31, 2013 and 2012.

	Earnings Per Share (“EPS”) — The number of shares outstanding at December 31, 2013 was 137,630,896. The Company applies the two-class method of computing basic EPS. Under the two-class method, EPS is determined for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. The Company’s restricted stocks, which receive dividends as declared, qualify as participating securities. Restricted stock units issued by the Company are not considered participating securities, as they do not have dividend distribution rights during the vesting period. Diluted EPS is calculated on the basis of the weighted average number of shares outstanding during the period plus potential dilutive shares.
	The following table sets forth earnings per share calculations for the year ended December 31, 2013, 2012 and 2011:

SEGMENT INFORMATION	'
SEGMENT INFORMATION	'
	NOTE 24—SEGMENT INFORMATION
	The Company utilizes an internal reporting system to measure the performance of various operating segments within the Bank and the Company overall. We have 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 and whose operating results are regularly reviewed by the Company’s chief operating decision-maker to make decisions about resources to be allocated to the segment and assess its performance and for which discrete financial information is available.
	The Retail Banking segment focuses primarily on retail operations through the Bank’s branch network, as well as originating consumer loans. The Commercial Banking segment, which includes commercial real estate, primarily generates commercial loans through the efforts of the commercial lending offices located in the Bank’s northern and southern California production offices. Furthermore, the Company’s Commercial Banking segment also 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 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. Transfer pricing assumptions and methodologies are reviewed at least annually to ensure that the Company’s process is reflective of current market conditions. The 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 provide a reasonable and consistent basis for the measurement of the Company’s business segments and product net interest margins. Changes to the Company’s transfer pricing and methodologies are approved by the Asset Liability Committee.
	The accounting policies of the segments are the same as those described in the summary of significant accounting policies. Operating segment results are based on the Company’s internal management reporting process, which reflects assignments and allocations of capital, certain operating and administrative costs and the provision for loan 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. 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 our 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, 2013, 2012, and 2011.

SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2013
SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES	'
Basis of Presentation	'
	Basis of Presentation — The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America and general practices within the banking industry. The following is a summary of significant principles used in the preparation of the accompanying financial statements. In preparing the financial statements, management of the Company has made a number of estimates and assumptions pertaining to the reporting of assets and liabilities, including the fair value of assets acquired and liabilities assumed, the FDIC indemnification asset, valuation of OREO, the allowance for loan losses, the disclosure of contingent assets and liabilities and the disclosure of income and expenses for the periods presented in conformity with accounting principles generally accepted in the United States of America. Actual results could differ from those estimates.
Principles of Consolidation	'
	Principles of Consolidation — The consolidated financial statements include the accounts of East West Bancorp, Inc., 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”). In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, the Trusts are not consolidated into the accounts of East West Bancorp, Inc.
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, may require us to make a number of significant judgments. Based on the observability of the inputs used in the valuation techniques, we classify our 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. In determining the fair value of financial instruments, we use market prices of the same or similar instruments whenever such prices are available. We do 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 analyses. These modeling techniques incorporate our 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.

	Securities Purchased Under Resale Agreements (“Resale Agreements”) — The Company purchases securities under resale agreements with terms that range from one day to several years. These agreements are collateralized by mortgage-backed securities and mortgage or commercial loans that are generally held by a third party custodian. The purchases are over-collateralized to ensure against unfavorable market price movements. In the event that the fair value of the securities decreases below the carrying amount of the related repurchase agreement, the counterparty is required to deliver an equivalent value of additional securities. The counterparties to these agreements are nationally recognized investment banking firms that meet credit eligibility criteria and with whom a master repurchase agreement has been duly executed. Resale agreements that are short-term in nature, or have terms of up to 90 days, are included in cash and cash equivalents. Resale agreements with terms greater than 90 days are separately categorized.
Investment Securities	'
	Investment Securities — The Company classifies its investment securities according to their purpose and holding period. Investment securities available-for-sale are reported at estimated fair value, with unrealized gains and losses excluded from operations and reported as a separate component of accumulated other comprehensive income or loss, net of tax, in stockholders’ equity.
	The fair values of the investment securities are generally determined by independent external pricing service providers who have experience in valuing these securities and by comparison to and/or average of quoted market prices obtained from independent external brokers. In obtaining such valuation information from third parties, the Company has evaluated the methodologies used to develop the resulting fair values. The Company performs a monthly analysis on the broker quotes and the third party pricing service quotes to ensure that the prices represent a reasonable estimate of the fair value. The procedures include, but are not limited to, initial and ongoing review of third party pricing methodologies, review of pricing trends, and monitoring of trading volumes. The Company considers whether prices received from independent brokers represent a reasonable estimate of fair value through the use of observable market inputs including comparable trades, the yield curve, spreads and, when available, market indices. As a result of this analysis, if the Company determines there is a more appropriate fair value based upon the available market data, the price received from the third party is adjusted accordingly. 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 that include observable market based inputs. Additionally, the majority of these independent broker quotations are non-binding.
	The Company applies a modified valuation approach to certain investment securities for which it believes the current broker prices obtained are based on forced liquidation or distressed sale values in inactive markets. The fair value of each of these securities is individually determined based on a combination of the market approach, reflecting current broker prices, and the income approach, which is a discounted cash flow approach. In calculating the fair value derived from the income approach, the Company makes assumptions related to the implied rate of return, general change in market rates, estimated changes in credit quality and liquidity risk premium, specific non-performance and default experience in the collateral underlying the security; additionally, broker discount rates are taken into consideration in determining the discount rate. The values resulting from each approach (i.e. market and income approaches) are weighted to derive the final fair value of each security trading in an inactive market.
	Amortization of premiums and accretion of discounts on securities are recorded as yield adjustments on such securities using the effective interest method. The specific identification method is used for purposes of determining cost in computing realized gains and losses on investment securities sold.
	At each reporting date, the Company assesses whether there is an “other-than-temporary” impairment (“OTTI”) in its portfolio of investment securities. If we determine that a decline in fair value is other-than-temporary, an impairment loss is recognized in current earnings. When we have the intent and ability to hold debt securities and it is not more likely than not that we will be required to sell these securities with OTTI for a period necessary to recover the noncredit-related impairment losses, only the credit-related impairment losses are recognized in current earnings. In these instances, the noncredit-related impairment losses are charged to other comprehensive income. The Company examines all individual securities that are in an unrealized loss position at each reporting date for other-than-temporary impairment. Specific investment level factors that are examined to assess impairment include the nature of the investments, the severity and duration of the loss, the probability that the Company will be unable to collect all amounts due, an analysis of the issuers of the securities and whether there has been any cause for default on the securities, and any change in the rating of the securities by the various rating agencies. Additionally, management takes into consideration the Company’s financial resources as well as the Company’s overall ability and intent to hold the securities and not be required to sell the securities until their fair values recover.
	The Company considers all available information relevant to the collectability of the security, including information about past events, current conditions, and reasonable and supportable forecasts, when developing the estimate of future cash flows and making its other-than-temporary impairment assessment for its portfolio of trust preferred securities. The Company considers factors such as remaining payment terms of the security, prepayment speeds, expected defaults, the financial condition of the issuer(s), and the value of any underlying collateral
Loans Receivable	'
	Loans Receivable — 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 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. Discounts or premiums on purchased loans are accreted or amortized to interest income using the effective interest method over the remaining period to contractual maturity adjusted for anticipated prepayments. Interest on loans is calculated using the simple-interest method on daily balances of the principal amounts outstanding. Accrual of interest is discontinued on a loan 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. Generally, loans are placed on nonaccrual status when they become 90 days past due. When interest accrual is discontinued, all unpaid accrued interest is reversed against interest income. In general, subsequent payments received are applied to the outstanding principal balance of the loan. 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.
	Loans held for sale are carried at the lower of aggregate cost or fair value using the aggregate method. 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 the computation of the gain or loss from the sale of the related loans. A valuation allowance is established if the fair value of such loans is lower than their cost, with a corresponding charge to noninterest income.
Troubled Debt Restructurings ("TDR")	'
	Troubled Debt Restructurings (“TDR”) — A loan is identified as a troubled debt restructure when a borrower is experiencing financial difficulties and for economic or legal reasons related to these difficulties the Company grants a concession to the borrower in the restructuring that it would not otherwise consider. The Company has granted a concession when, as a result of the restructuring to a troubled borrower, it does not expect to collect all amounts due, including principal and/or interest accrued at the original terms of the loan. 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, or a note split with principal forgiveness. A restructuring executed at an interest rate that is at market interest rates is not a TDR. All troubled debt restructurings are reviewed for impairment. For modifications where we forgive principal, the entire amount of such principal forgiveness is immediately charged off. Generally, a nonaccrual loan that is restructured remains on nonaccrual status for a period of six months to demonstrate that the borrower can perform under the restructured terms. However, the borrower’s performance prior to the restructuring, or other significant events at the time of restructuring may be considered in assessing whether the borrower can meet the new terms and may result in the loan remaining on accrual status or being returned to accrual status after a shorter performance period. If the borrower’s performance under the new terms is not reasonably assured, the loan remains classified as a nonaccrual loan. Loans classified as TDRs are reported as impaired loans.
Allowance for Loan Losses	'
	Allowance for Loan Losses — The allowance for loan losses is established as management’s estimate of probable losses inherent in the loan portfolio. The allowance is increased by the provision for loan losses and decreased by charge-offs when management believes the uncollectability of a loan is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based on management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral and prevailing economic conditions. This 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.
	A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all scheduled payments of principal or interest due according to the 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 delay, 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. Impairment is measured on a loan-by-loan basis for residential, commercial real estate, and commercial and industrial loans based on the loan’s observable market price or the fair value of the collateral, less costs to sell, if the loan is collateral dependent, or the present value of expected future cash flows discounted at the loan’s effective interest rate. If the measure of the impaired loan is less than the recorded investment in the loan and the loan is classified as nonperforming and uncollectible, the deficiency is charged off against the allowance for loan losses. In general, consumer loans consist of homogeneous smaller balance loans and are collectively evaluated for impairment.
Acquired Loans	'
	Acquired Loans — Acquired loans are valued as of acquisition date in accordance with ASC 805. Loans purchased with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are accounted for under ASC 310-30.
	Under ASC 805 and 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. In situations where loans have similar risk characteristics, loans are 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 loan or pool are estimated using an internal cash flow model that projects cash flows and calculates the carrying value of the loan or pool, book yield, effective interest income and impairment, if any, based on loan or pool level events, respectively. Assumptions as to default rates, loss severity, loss curves and prepayment speeds are utilized to calculate the expected cash flows.
	At acquisition, the excess of the cash flows expected to be collected over the recorded investment is considered to be the accretable yield and is recognized as interest income over the life of the loan or pool. The excess of the contractual cash flows over the cash flows expected to be collected is considered to be the nonaccretable difference. Subsequent to the acquisition date, any increases in expected cash flows over those expected 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 those expected at purchase date that are probable are recognized by recording an allowance 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.
Covered Loans	'
	Covered Loans — Loans acquired in an FDIC-assisted acquisition that are subject to an FDIC shared-loss agreement are referred to as covered loans. Covered loans are reported exclusive of the expected cash flow reimbursements we expect to collect from the FDIC. All covered loans are accounted for under ASC 805 and ASC 310-30.
FDIC Indemnification Asset	'
	FDIC Indemnification Asset — In conjunction with the FDIC-assisted acquisitions of Washington First International Bank and United Commercial Bank, the Bank entered into shared-loss agreements with the FDIC related to covered loans and covered other real estate owned (see “Covered Other Real Estate Owned” below). The FDIC indemnification asset is initially recorded at fair value, based on the discounted value of expected future cash flows under the shared-loss agreement. The Company has elected to account for amounts receivable under the shared-loss agreements as an indemnification asset in accordance with ASC 805. The difference between the present value and the undiscounted cash flows the Company expects to collect from the FDIC is accreted into noninterest income over the life of the FDIC indemnification asset. The FDIC indemnification asset is reviewed quarterly and adjusted for any changes in expected cash flows based on recent performance and expectations for future performance of the covered portfolio. These adjustments are measured on the same basis as the related covered loans and covered other real estate owned. Any increases in cash flow of the covered loans over those expected will reduce the FDIC indemnification asset and any decreases in cash flow of the covered loans over those expected will increase the FDIC indemnification asset. Over the life of the FDIC indemnification asset, increases and decreases are recorded as adjustments to noninterest income. During the year, the bank lowered the credit discount on the UCB covered loan portfolio as the credit quality was performing better than originally estimated. By lowering the credit discount, interest income will increase over the life of the loans. Correspondingly, with the lowered credit discount, the expected reimbursement from the FDIC under the loss sharing agreement will decrease, resulting in amortization of the FDIC indemnification asset which is recorded as a charge to noninterest income.
Other Real Estate Owned	'
	Other Real Estate Owned — Other real estate owned (“OREO”) represents properties acquired through foreclosure or through full or partial satisfaction of loans, is considered held for sale, and is recorded at the lower of cost or estimated fair value at the time of foreclosure. Loan balances in excess of the fair value of the real estate acquired at the date of foreclosure are charged against the allowance for loan losses. After foreclosure, the real estate is carried at the lower of carrying value or fair value less costs to sell. Subsequent declines in the fair value of OREO below the carrying value are recorded through the use of a valuation allowance by charges to noninterest expense. Any subsequent operating expenses or income of such properties are also charged to noninterest expense. If the OREO is sold within three months of foreclosure, the Company substitutes the value received in the sale (net of costs to sell) for the fair value (less costs to sell). Any adjustment made to the loss originally recognized at the time of foreclosure is then charged against or credited to the allowance for loan losses, if deemed material. Otherwise, any declines in value, after foreclosure, are recorded in non-interest expense as gains or losses from the sale or disposition of the real estate. Gain recognition upon disposition of a property is dependent on the sale having met certain criteria relating to the buyer’s initial investment in the property sold.
Covered Other Real Estate Owned	'
	Covered Other Real Estate Owned — All other real estate owned acquired in an FDIC-assisted acquisition that are subject to an FDIC shared-loss agreement are referred to as covered other real estate owned. Covered other real estate owned is reported exclusive of the expected cash flow reimbursements we expect to collect from the FDIC. Upon transferring covered loan collateral to covered other real estate owned status, acquisition date fair value discounts on the related loan are also transferred to covered other real estate owned. Fair value adjustments on covered other real estate owned result in a reduction of the covered other real estate carrying amount through expense and a corresponding increase of the FDIC reimbursement for 80% of the adjustment resulting in income.  The net of that expense and income is the non-reimbursed portion or 20% of the estimated loss to the Bank which is the net amount charged against earnings.
Investment in Affordable Housing Partnerships	'
	Investment in Affordable Housing Partnerships — The Company owns limited partnership interests in projects of affordable housing for lower income tenants. The investments in which the Company has a limited partnership interest that exceeds 5% are recorded using the equity method of accounting. The remaining investments are recorded using the cost method and are being amortized over the life of the related tax credits. The tax credits are being recognized in 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 and Other Intangible Assets — The Company has goodwill, which represents the excess of the purchase price over the fair value of net assets acquired, as a result of 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. Premiums on deposits, 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 premiums on deposits is recognized by writing down the asset to the extent that the carrying value exceeds the estimated fair value.
Investment in Federal Home Loan Bank Stock	'
	Investment in Federal Home Loan Bank Stock — As a member of the Federal Home Loan Bank (“FHLB”) of San Francisco, the Bank is required to own common stock in the FHLB of San Francisco based upon our balance of residential mortgage loans and outstanding FHLB advances. As a result of the acquisition of WFIB in 2010, the Bank also owns common stock in the FHLB of Seattle. FHLB stock is carried at cost and may be sold back to the FHLB at its carrying value. Cash dividends are accrued and reported as dividend income.
Investment in Federal Reserve Bank Stock	'
	Investment in Federal Reserve Bank Stock — As a member of the Federal Reserve Bank (“FRB”) of San Francisco, the Bank is required to maintain stock in the FRB of San Francisco based on a specified ratio relative to our capital. FRB stock is carried at cost and may be sold back to the FRB at its carrying value. Cash dividends are accrued and reported as dividend income.
Premises and Equipment	'
	Premises and Equipment — 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 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 circumstances indicate that the carrying amount of these assets may not be recoverable. An asset is considered impaired when the expected undiscounted cash flows over the remaining useful life is less than the net book value. When impairment is indicated for an asset, the amount of impairment loss is the excess of the net book value over its fair value.
Securities Sold Under Repurchase Agreements ("Repurchase Agreements")	'
	Securities Sold Under Repurchase Agreements (“Repurchase Agreements”) — The Company sells securities under repurchase agreements. These transactions are accounted for as collateralized financing transactions and recorded at the amounts at which the securities were sold. The Company may have to provide additional collateral to the counterparty, as necessary.
Long-Term Debt	'
	Long-Term Debt — Long-term debt consists of junior subordinated debt and other long-term debt. The Company has six statutory business trusts whereby the Company is the owner of all the beneficial interests represented by the common securities of the Trusts, and third parties hold the fixed and variable rate capital 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. However, these securities will be phased out of the Tier I capital beginning in 2013, fully phased out by 2016.
	The Trusts are not consolidated by the Company. Junior subordinated debt represents liabilities of the Company to the Trusts and is included in long-term debt on the accompanying consolidated balance sheets.
Federal Funds Purchased	'
	Federal Funds Purchased — The Company utilizes federal funds purchased as part of its short-term financing strategy. Federal funds purchased are generally overnight borrowings and mature within one business day to six months from the transaction date.
Income Taxes	'
	Income Taxes — Deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each year-end, based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income.
	The Company examines its 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. The Company recognizes interest and penalties related to tax positions as part of its provision for income taxes.
Stock Based Compensation	'
	Stock-Based Compensation — The Company issues stock-based compensation to certain employees, officers, and directors and accounts for stock options using the fair value method, which generally results in compensation expense recognition.
Transfers and Servicing of Financial Assets and Extinguishments of Liabilities	'
	Transfers and Servicing of Financial Assets and Extinguishments of Liabilities — Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company; (2) the transferee has the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets; and (3) the Company does not maintain effective control over the transferred assets through either (a) an agreement that entitles and obligates the Company to repurchase or redeem them before their maturity or (b) an agreement that provides the Company with both the unilateral ability to cause the holder to return specific assets and a more than trivial benefit attributable to that ability. The difference between the net proceeds received and the carrying amount of the financial assets being sold is recognized as a gain or loss on sale.
Earnings Per Share ("EPS")	'
	Earnings Per Share (“EPS”) — The Company applies the two-class method of computing EPS. Under the two-class method, EPS is determined for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. The Company’s restricted stock, which receive dividends as declared, qualify as participating securities. Restricted stock units issued by the Company are not considered participating securities, as they do not have dividend distribution rights during the vesting period. Diluted EPS is calculated on the basis of the weighted average number of shares outstanding during the period plus potential dilutive shares.
Comprehensive Income	'
	Comprehensive Income — The term “comprehensive income” describes the total of all components of comprehensive income, including net income and other comprehensive income. “Other comprehensive income” refers to revenues, expenses, and gains and losses that are included in comprehensive income but are excluded from net income because they have been recorded directly in equity under the provisions of other Financial Accounting Standards Board statements. In accordance with the adoption of ASU 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income, the Company presents comprehensive income in the consolidated statements of comprehensive income, which was formerly presented in the consolidated statements of changes in stockholders’ equity.
Derivative Financial Instruments	'
	Derivative Financial Instruments — 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. All derivative instruments, including certain derivative instruments embedded in other contracts, are recognized on the consolidated balance sheet at fair value with the change in fair value reported in earnings. When master netting agreements exist, the Company nets counterparty positions with any cash collateral received or delivered.
	The Company’s interest rate swaps on certain certificates of deposit qualify for hedge accounting treatment under ASC 815, Derivatives and Hedging. The Company documents its hedge relationships, 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. This includes designating the derivative contract as a “fair value hedge” which is a hedge of a recognized asset or liability. All derivatives designated as fair value hedges are linked to specific hedged items or to groups of specific assets and liabilities on the balance sheet. Both at inception and quarterly thereafter, the Company assesses whether the derivatives used in hedging transactions are highly effective (as defined in the guidance) in offsetting changes in the fair value of the hedged item. Retroactive effectiveness is also assessed as well as the continued expectation that the hedge will remain effective prospectively. Any ineffective portion of the changes of fair value hedges is recognized immediately in interest expense in the consolidated statements of income.
	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 derivative instrument is terminated or the hedge designation removed, the previous adjustments to the carrying amount of the hedged liability would be subsequently accounted for in the same manner as other components of the carrying amount of that liability. For interest-bearing liabilities, such adjustments would be amortized into earnings over the remaining life of the respective liability.
	The Company also offers various derivative products to clients and enters into derivative transactions in due course. These transactions are not linked to specific Company assets or liabilities in 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 each reporting period with changes in fair value recorded in the consolidated statements of income.
Reclassifications	'
	Reclassifications — Certain items in the consolidated balance sheet and the consolidated statements of income for the years ended December 31, 2012 and 2011 were reclassified to conform to the 2013 and 2012 presentation, respectively. These reclassifications did not affect previously reported net income.

The Company has elected to account for covered loans acquired in the FDIC-assisted acquisitions under ASC 310-30, excluding any additional advances subsequent to acquisition date.

[2]

This allowance is related to drawdowns on commitments that were in existence as of the acquisition dates of WFIB and UCB and, therefore, are covered under the shared-loss agreements with the FDIC. Allowance on these subsequent drawdowns is accounted for as part of the allowance for loan losses.
