Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 — Summary of Significant Accounting Policies
	Summary of Operations
	Hanmi Financial Corporation (“Hanmi Financial,” the “Company,” “we,” “us” or “our”) was formed as a holding company of Hanmi Bank (the “Bank”) and registered with the Securities and Exchange Commission under the Act on March 17, 2001. Subsequent to its formation, each of the Bank’s shares was exchanged for one share of Hanmi Financial with an equal value. Our primary operations are related to traditional banking activities, including the acceptance of deposits and the lending and investing of money through operation of the Bank.
	On August 31, 2014, Hanmi Financial completed its acquisition of Central Bancorp, Inc., a Texas corporation (“CBI”) See “Note 2 — Acquisition.” During the second quarter of 2014, we sold two subsidiaries, Chun-Ha Insurance Services, Inc., a California corporation (“Chun-Ha”), and All World Insurance Services, Inc., a California corporation (“All World”). See “Note 4 — Sale of Insurance Subsidiaries and Discontinued Operations.”
	The Bank is a community bank conducting general business banking, with its primary market encompassing the Korean-American community as well as other ethnic communities across California, Texas, Illinois, Virginia, New Jersey, and New York. The Bank’s full-service offices are located in markets where many of the businesses are run by immigrants and other minority groups. The Bank’s client base reflects the multi-ethnic composition of these communities. The Bank is a California state-chartered financial institution insured by the FDIC. As of December 31, 2014, the Bank maintained a network of 49 full-service branch offices in California, Texas, Illinois, Virginia, New Jersey and New York, and loan production offices in California, Colorado, Texas, Virginia, and Washington State.
	Basis of Presentation
	The accounting and reporting policies of Hanmi Financial and subsidiaries conform, in all material respects, to U.S. generally accepted accounting principles (“GAAP”) and general practices within the banking industry. The information set forth in the following notes is presented on a continuing operations basis, unless otherwise noted. The following is a summary of the significant accounting policies consistently applied in the preparation of the accompanying Consolidated Financial Statements.
	Principles of Consolidation
	The Consolidated Financial Statements include the accounts of Hanmi Financial and our wholly-owned subsidiary, the Bank. In addition, the accounts of Chun-Ha and All World are included for all periods presented through the date of sale, June 30, 2014. All intercompany transactions and balances have been eliminated in consolidation.
	Use of Estimates in the Preparation of Financial Statements
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant areas where estimates are made consist of the allowance for loan losses, other-than-temporary impairment, investment securities valuations, purchase credit impaired loans, the fair values of assets and liabilities acquired in a business combination and income taxes. Actual results could differ from those estimates.
	Reclassifications
	Certain reclassifications were made to the prior year’s presentation to conform to the current year’s presentation.
	Cash and Cash Equivalents
	Cash and cash equivalents include cash, due from banks, overnight federal funds sold and Treasury bills, all of which have original or purchased maturities of less than 90 days.
	Investment Securities
	Securities are classified into three categories and accounted for as follows:

		(i)	Securities that we have the positive intent and ability to hold to maturity are classified as “held to maturity” and reported at amortized cost;

		(ii)	Securities that are bought and held principally for the purpose of selling them in the near future are classified as “trading securities” and reported at fair value. Unrealized gains and losses are recognized in earnings; and

		(iii)	Securities not classified as held to maturity or trading securities are classified as “available for sale” and reported at fair value. Unrealized gains and losses are reported as a separate component of stockholders’ equity as accumulated other comprehensive income, net of income taxes.

	Accreted discounts and amortized premiums on investment securities are included in interest income using the effective interest method over the remaining period to the call date or contractual maturity and, in the case of mortgage-backed securities and securities with call features, adjusted for anticipated prepayments. Unrealized and realized gains or losses related to holding or selling of securities are calculated using the specific-identification method.
	We review investment securities on an ongoing basis for the presence of other-than-temporary impairment (“OTTI”) or permanent impairment, taking into consideration current market conditions, fair value in relationship to cost, extent and nature of the change in fair value, issuer rating changes and trends, whether we intend to sell a security or if it is likely that we will be required to sell the security before recovery of our amortized cost basis of the investment, which may be maturity, and other factors.
	For debt securities, the classification of OTTI depends on whether we intend to sell the security or if it is more likely than not that we will be required to sell the security before recovery of its cost basis, and on the nature of the impairment. If we intend to sell a security or if it is more likely than not that we will be required to sell the security before recovery, an OTTI write-down is recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value. If we do not intend to sell the security or it is not more likely than not that we will be required to sell the security before recovery, the OTTI write-down is separated into an amount representing credit loss, which is recognized in earnings, and the amount related to all other factors, which is recognized in other comprehensive income net of tax. A credit loss is the difference between the cost basis of the security and the present value of cash flows expected to be collected, discounted at the security’s effective interest rate at the date of acquisition. The cost basis of an other than temporarily impaired security is written down by the amount of impairment recognized in earnings. The new cost basis is not adjusted for subsequent recoveries in fair value.
	Loans Receivable
	Originated loans: Loans are originated by the Company with the intent to hold them for investment and are stated at the principal amount outstanding, net of unearned income. Unearned income includes deferred unamortized nonrefundable loan fees and direct loan origination costs. Net deferred fees or costs are recognized as an adjustment to interest income over the contractual life of the loans using the effective interest method or taken into income when the related loans are paid off or sold. The amortization of loan fees or costs is discontinued when a loan is placed on nonaccrual status. Interest income is recorded on an accrual basis in accordance with the terms of the respective loan and includes prepayment penalties.
	Purchased loans: Purchased loans are stated at the principal amount outstanding, net of unearned discounts or unamortized premiums. All loans acquired in our acquisitions are initially measured and recorded at their fair value on the acquisition date. A component of the initial fair value measurement is an estimate of the credit losses over the life of the purchased loans. Purchased loans are also evaluated for impairment as of the acquisition date and are accounted for as “acquired non-impaired” or “purchased credit impaired” loans.
	Acquired non-impaired loans: Acquired non-impaired loans are those loans for which there was no evidence of credit deterioration at their acquisition date and it was probable that we would be able to collect all contractually required payments. Acquired non-impaired loans, together with originated loans, are referred to as non-purchased credit impaired (“Non-PCI”) loans. Purchase discount or premium on acquired non-impaired loans is recognized as an adjustment to interest income over the contractual life of such loans using the effective interest method or taken into income when the related loans are paid off or sold.
	Purchased credit impaired loans. Purchased credit impaired (“PCI”) loans are accounted for in accordance with ASC Subtopic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” A purchased loan is deemed to be credit impaired when there is evidence of credit deterioration since its origination and it is probable at the acquisition date that we would be unable to collect all contractually required payments. We apply PCI loan accounting when (i) we acquire loans deemed to be impaired, and (ii) as a general policy election for non-impaired loans that we acquire in a distressed bank acquisition.
	For PCI loans, at the time of acquisition we (i) calculated the contractual amount and timing of undiscounted principal and interest payments (the “undiscounted contractual cash flows”) and (ii) estimated the amount and timing of undiscounted expected principal and interest payments (the “undiscounted expected cash flows”). The difference between the undiscounted contractual cash flows and the undiscounted expected cash flows is the nonaccretable difference. The nonaccretable difference represents an estimate of the loss exposure of principal and interest related to the PCI loan portfolios; such amount is subject to change over time based on the performance of such loans. The carrying value of PCI loans is reduced by payments received, both principal and interest, and increased by the portion of the accretable yield recognized as interest income.

	The excess of expected cash flows at acquisition over the initial fair value of acquired impaired loans is referred to as the “accretable yield” and is recorded as interest income over the estimated life of the loans using the effective yield. If estimated cash flows are indeterminable, the recognition of interest income will cease to be recognized.
	At acquisition, the Company may aggregate PCI loans into pools having common credit risk characteristics such as product type, geographic location and risk rating. Increases in expected cash flows over those previously estimated increase the accretable yield and are recognized as interest income prospectively. Decreases in the amount and changes in the timing of expected cash flows compared to those previously estimated decrease the accretable yield and usually result in a provision for loan losses and the establishment of an allowance for loan losses. As the accretable yield increases or decreases from changes in cash flow expectations, the offset is a decrease or increase to the nonaccretable difference. The accretable yield is measured at each financial reporting date based on information then currently available and represents the difference between the remaining undiscounted expected cash flows and the current carrying value of the loans.
	PCI loans that are contractually past due are still considered to be accruing and performing as long as there is an expectation that the estimated cash flows will be received. If the timing and amount of cash flows is not reasonably estimable, the loans may be classified as nonaccrual with interest income recognized on either a cash basis or as a reduction of the principal amount outstanding.
	Non-PCI loans are placed on nonaccrual status when, in the opinion of management, the full timely collection of principal or interest is in doubt. Generally, the accrual of interest is discontinued when principal or interest payments become more than 90 days past due. However, in certain instances, we may place a particular loan on nonaccrual status earlier, depending upon the individual circumstances surrounding the loan’s delinquency. When an asset is placed on nonaccrual status, previously accrued but unpaid interest is reversed against current income. Subsequent collections of cash are applied as principal reductions when received, except when the ultimate collectability of principal is probable, in which case interest payments are credited to income. Nonaccrual assets may be restored to accrual status when principal and interest become current and full repayment is expected. Interest income is recognized on the accrual basis for impaired loans not meeting the criteria for nonaccrual.
	Nonperforming assets consist of loans on nonaccrual status, loans 90 days or more past due and still accruing interest, loans restructured with troubled borrowers where the terms of repayment have been renegotiated resulting in a reduction or deferral of interest or principal, and other real estate owned (“OREO”). Loans are generally placed on nonaccrual status when they become 90 days past due unless management believes the loan is adequately collateralized and in the process of collection. Additionally, the Bank may place loans that are not 90 days past due on nonaccrual status, if management reasonably believes the borrower will not be able to comply with the contractual loan repayment terms and collection of principal or interest is in question.
	Loans Held for Sale
	Loans originated, or transferred from loans receivable, and intended for sale in the secondary market are carried at the lower of aggregate cost or fair market value. Fair market value, if lower than cost, is determined based on valuations obtained from market participants or the value of underlying collateral, calculated individually. A valuation allowance is established if the market value of such loans is lower than their cost and net unrealized losses, if any, are recognized through a valuation allowance by charges to income. 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.
	Allowance for Loan Losses on Non-PCI Loans
	Management believes the allowance for loan losses is adequate to provide for probable losses inherent in the loan portfolio. However, the allowance is an estimate that is inherently uncertain and depends on the outcome of future events. Management’s estimates are based on previous loan loss experience; volume, growth and composition of the loan portfolio; the value of collateral; and current economic conditions. Our lending is concentrated generally in commercial, consumer, construction and real estate loans primarily in California, Illinois, and Texas.
	Provisions to allowance for loan losses are made quarterly to recognize probable loan losses. The quarterly provision is based on the allowance need, which is determined through analysis involving quantitative calculations based on historic loss rates for general reserves and individual impairment calculations for specific allocations to impaired loans as well as qualitative adjustments.
	In the first quarter of 2010, the look-back period was reduced from twelve quarters to eight quarters, with 60 percent weighting given to the most recent four quarters and 40 percent to the oldest four quarters, to place greater emphasis on losses taken by the Bank during the economic downturn. In the second quarter of 2013, management reevaluated the look-back period and restored the twelve quarter look-back period, with 50 percent weighting given to the most recent four quarters, 33 percent to the next four quarters and 17 percent to the oldest four quarters, in order to capture a period of higher losses that would have otherwise been excluded. In the first quarter of 2014, management again evaluated the look-back period and extended the periods to sixteen quarters to continue capturing a period of higher losses that would have been dropped off and to reflect potential losses in our current credit portfolio. Risk factor calculations are weighted at 46.0 percent for the first four quarters, 31.0 percent for the second four quarters, 15.0 percent for the third four quarters, and 8.0 percent for the last four quarters. The change in methodology maintained the Bank’s allowance at a level consistent with the prior quarter.
	To determine general reserve requirements, existing loans are divided into 11 general loan pools of risk-rated loans as well as three homogenous loan pools. For risk-rated loans, migration analysis allocates historical losses by loan pool and risk grade to determine risk factors for potential loss inherent in the current outstanding loan portfolio. As 3 homogeneous loans are bulk graded, the risk grade is not factored into the historical loss analysis. In addition, specific reserves are allocated for loans deemed “impaired.”
	When determining the appropriate level for allowance for loan losses, management considers qualitative adjustments for any factors that are likely to cause estimated credit losses associated with the Bank’s current portfolio to differ from historical loss experience, including, but not limited to, national and local economic and business conditions, volume and geographic concentrations, and problem loan trends.
	To systematically quantify the credit risk impact of trends and changes within the loan portfolio, a credit risk matrix is utilized. The qualitative factors are considered on a loan pool by loan pool basis subsequent to, and in conjunction with, a loss migration analysis. The credit risk matrix provides various scenarios with positive or negative impact on the portfolio along with corresponding basis points for qualitative adjustments.
	Loan losses are charged off, and recoveries are credited, to the allowance account. Additions to the allowance account are charged to the provision for credit losses. The allowance for loan losses is maintained at a level considered adequate by management to absorb probable losses in the loan portfolio. The adequacy of the allowance is determined by management based upon an evaluation and review of the loan portfolio, consideration of historical loan loss experience, current economic conditions, changes in the composition of the loan portfolio, analysis of collateral values and other pertinent factors.
	Loans are measured for impairment when it is probable that not all amounts, including principal and interest, will be collected in accordance with the original contractual terms of the loan agreement. The amount of impairment and any subsequent changes are recorded through the provision for credit losses as an adjustment to the allowance for loan losses.
	The Bank follows the “Interagency Policy Statement on the Allowance for Loan and Lease Losses” and, as an integral part of the quarterly credit review process, the allowance for loan losses and allowance for off-balance sheet items are reviewed for adequacy. The California Department of Business Oversight and/or the Board of Governors of the Federal Reserve System (“Federal Reserve”) require the Bank to recognize additions to the allowance for loan losses based upon their assessment of the information available to them at the time of their examinations.
	In general, the Bank will charge off a loan and declare a loss when its collectability is questionable and when the Bank can no longer justify presenting the loan as an asset on its balance sheet. To determine if a loan should be charged off, all possible sources of repayment are analyzed, including the potential for future cash flow from income or liquidation of other assets, the value of any collateral, and the strength of co-makers or guarantors. When these sources do not provide a reasonable probability that principal can be collected in full, the Bank will fully or partially charge off the loan.
	For a real estate loan, including commercial term loans secured by collateral, any impaired portion is considered as loss if the loan is more than 90 days past due. In a case where the fair value of collateral is less than the loan balance and the borrower has no other assets or income to support repayment, the amount of the deficiency is considered a loss and charged off.
	For a commercial and industrial loan other than those secured by real estate, if the borrower is in the process of a bankruptcy filing in which the Bank is an unsecured creditor or deemed virtually unsecured by lack of collateral equity or lien position and the borrower has no realizable equity in assets and prospects for recovery are negligible, the loan is considered a loss and charged off. Additionally, a commercial and industrial unsecured loan that is more than 120 days past due is considered a loss and charged off.
	For an unsecured consumer loan where a borrower files for bankruptcy, the loan is considered a loss within 60 days of receipt of notification of filing from the bankruptcy court. Other consumer loans are considered a loss if they are more than 90 days past due. Other events, such as bankruptcy, fraud, or death result in charge offs being recorded in an earlier period.
	Allowance for Loan Losses on PCI Loans
	The PCI loans are subject to our internal and external credit review. If deterioration in the expected cash flows results in a reserve requirement, a provision for credit losses is charged to earnings. For PCI loans, the allowance for loan losses is measured at the end of each financial reporting period based on expected cash flows. Decreases or increases in the amount and changes in the timing of expected cash flows on the PCI loans as of the financial reporting date compared to those previously estimated are usually recognized by recording a provision or a negative provision for credit losses on such loans.

	Impaired Loans
	Loans are identified and classified as impaired when it is probable that not all amounts, including principal and interest, will be collected in accordance with the contractual terms of the loan agreement. The Bank will consider the following loans as impaired: nonaccrual loans or loans where principal or interest payments have been contractually past due for 90 days or more, unless the loan is both well-collateralized and in the process of collection; loans classified as troubled debt restructuring loans.
	The Bank considers whether the borrower is experiencing problems such as operating losses, marginal working capital, inadequate cash flow or business deterioration in realizable value. The Bank also considers the financial condition of a borrower who is in industries or countries experiencing economic or political instability.
	When a loan is considered impaired, any future cash receipts on such loans will be treated as either interest income or return of principal depending upon management’s opinion of the ultimate risk of loss on the individual loan. Cash payments are treated as interest income where management believes the remaining principal balance is fully collectible.
	We evaluate loan impairment in accordance with applicable GAAP. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as a practical 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, the deficiency will be charged off against the allowance for loan losses or, alternatively, a specific allocation will be established. Additionally, impaired loans are specifically excluded from the quarterly migration analysis when determining the amount of the allowance for loan losses required for the period.
	For impaired loans where the impairment amount is measured based on the present value of expected future cash flows discounted at the loan’s original effective interest rate, any impairment that represents the change in present value attributable to the passage of time is recognized as provision for credit losses.
Troubled Debt Restructuring
A loan is identified as a troubled debt restructuring (“TDR”) when a borrower is experiencing financial difficulties and, for economic or legal reasons related to these difficulties, the Bank grants a concession to the borrower in the restructuring that it would not otherwise consider. The Bank has granted a concession when, as a result of the restructuring, 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. TDRs are reviewed for potential impairment. 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. 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.
Premises and Equipment
Premises and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are computed 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 improvements		10 to 30 years
Furniture and equipment		3 to 10 years
Leasehold improvements		Term of lease or useful life, whichever is shorter
Software		3 years
Impairment of Long-Lived Assets
We account for long-lived assets in accordance with the provisions of FASB ASC 360, “Property, Plant and Equipment.” This requires that long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net undiscounted cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Other Real Estate Owned
Assets acquired through loan foreclosure are recorded at the lower of cost or fair value less estimated costs to sell when acquired. If fair value declines subsequent to foreclosure, valuation impairment is recorded through expense. Operating costs after acquisition are expensed.
Servicing Assets and Servicing liabilities
Servicing assets and servicing liabilities are initially recorded at fair value in accordance with the provisions of FASB ASC 860, “Transfers and Servicing.” The fair values of servicing assets and servicing liabilities represent either the price paid if purchased, or the allocated carrying amounts based on relative values when retained in a sale. Servicing assets and servicing liabilities are amortized in proportion to, and over the period of, estimated net servicing income. The fair value of servicing assets and servicing liabilities are determined based on the present value of estimated net future cash flows related to contractually specified servicing fees and costs.
The servicing assets and servicing liabilities are recorded based on the present value of the contractually specified servicing fee, net of adequate compensation, for the estimated life of the loan, using a discount rate and a constant prepayment rate. Management periodically evaluates the servicing assets and servicing liabilities for impairment. Impairment, if it occurs, is recognized in a valuation allowance in the period of impairment.
Interest-only strips are recorded based on the present value of the excess of total servicing fee over the contractually specified servicing fee for the estimated life of the loan, calculated using the same assumptions as noted above. Such interest-only strips are accounted for at their estimated fair value, with unrealized gains or losses recorded as adjustments to accumulated other comprehensive income (loss).
Other Intangible Assets
Other intangible assets consist of acquired intangible assets arising from acquisitions, including core deposit intangibles, trade names, client/insured relationships and carrier relationships. The acquired intangible assets were initially measured at fair value and then are amortized on the straight-line method over their estimated useful lives.
As required by FASB ASC 350, other intangible assets are assessed for impairment or recoverability whenever events or changes in circumstances indicate the carrying amount may not be recoverable.
Federal Home Loan Bank Stock
The Bank is a member of the Federal Home Loan Bank (“FHLB”) of San Francisco and is required to own common stock in the FHLB based upon the Bank’s balance of outstanding FHLB advances. FHLB stock is carried at cost and may be sold back to the FHLB at its carrying value. FHLB stock is periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends received are reported as dividend income.
Federal Reserve Bank Stock
The Bank is a member of the Federal Reserve Bank (“FRB”) of San Francisco and is required to maintain stock in the FRB based on a specified ratio relative to the Bank’s capital. FRB stock is carried at cost and may be sold back to the FRB at its carrying value. FRB stock is periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends received are reported as dividend income.
Bank-Owned Life Insurance
We have purchased single premium life insurance policies (“bank-owned life insurance”) on certain officers. The Bank is the beneficiary under the policy. In the event of the death of a covered officer, we will receive the specified insurance benefit from the insurance carrier. Bank-owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due, if any, that are probable at settlement.
Affordable Housing Investments
The Bank has invested in limited partnerships formed to develop and operate affordable housing units for lower income tenants throughout California. The partnership interests are accounted for utilizing the proportional amortization method with amortization expense and tax benefits recognized through the income tax provision in accordance with ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects.

Income Tax
We provide for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized.
Share-Based Compensation
We adopted FASB ASC 718, “Compensation-Stock Compensation,” on January 1, 2006 using the “modified prospective” method. Under this method, awards that are granted, modified or settled after December 31, 2005 are measured and accounted for in accordance with FASB ASC 718. Also under this method, expense is recognized for services attributed to the current period for unvested awards that were granted prior to January 1, 2006, based upon the fair value determined at the grant date under SFAS No. 123, “Accounting for Stock-Based Compensation.”
FASB ASC 718 requires that cash flows resulting from the realization of excess tax benefits recognized on awards that were fully vested at the time of adoption of FASB ASC 718 be classified as a financing cash inflow and an operating cash outflow on the Consolidated Statements of Cash Flows. Before the adoption of FASB ASC 718, we presented all tax benefits realized from the exercise of stock options as an operating cash inflow.
In addition, FASB ASC 718 requires that any unearned compensation related to awards granted prior to the adoption of FASB ASC 718 be eliminated against the appropriate equity accounts. As a result, the presentation of stockholders’ equity was revised to reflect the transfer of the balance previously reported in unearned compensation to additional paid-in capital.
Earnings per Share
Basic earnings per share is computed by dividing earnings available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution of securities that could share in the earnings.
Treasury Stock
We use the cost method of accounting for treasury stock. The cost method requires us to record the reacquisition cost of treasury stock as a deduction from stockholders’ equity on the Consolidated Balance Sheets.
Business Combinations
Business combinations completed after January 1, 2009, are accounted for under the acquisition method of accounting in accordance with ASC Topic 805, “Business Combinations.” Under the acquisition method, the acquiring entity in a business combination recognizes 100 percent of the acquired assets and assumed liabilities, regardless of the percentage owned, at their estimated fair values as of the date of acquisition. Any excess of the purchase price over the fair value of net assets and other identifiable intangible assets acquired is recorded as goodwill. To the extent the fair value of net assets acquired, including other identifiable assets, exceeds the purchase price, a bargain purchase gain is recognized. Assets acquired and liabilities assumed from contingencies must also be recognized at fair value, if the fair value can be determined during the measurement period. Results of operations of an acquired business are included in the statement of earnings from the date of acquisition. Acquisition-related costs, including conversion and restructuring charges, are expensed as incurred.
Recently Issued Accounting Standards
FASB ASU 2014-17, *Pushdown Accounting (a consensus of the FASB Emerging Issues Task Force)*, which allows an acquired entity to elect to apply pushdown accounting in its separate financial statements on a change-in-control event. The acquired entity elects whether to apply pushdown accounting individually for each change-in-control event, and may apply pushdown accounting during the reporting period in which the change-in-control event occurs. Effective November 18, 2014, an acquired entity may apply ASU 2014-17 to future change-in-control events. The Company did not make an election to apply FASB ASU 2014-17 for the acquisition of CBI, which has no impact on our financial condition or result of operations.

FASB ASU 2014-08, *Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity*, was issued to change the criteria for reporting discontinued operations and requires additional disclosures about discontinued operations. ASU 2014-08 requires that an entity report as a discontinued operation only a disposal that represents a strategic shift in operations that has a major effect on its operations and financial results. ASU 2014-08 is effective prospectively for new disposals (or classifications as held-for-sale) that occur within annual periods beginning on or after December 15, 2014, and interim periods within those annual periods, for public business entities and not-for-profit entities that have issued (or are a conduit obligor for) securities that are traded, listed, or quoted on an exchange or an over-the-counter market. For other entities, the ASU is effective for disposals (or classifications as held-for-sale) that occur within annual periods beginning on or after December 15, 2014, and interim periods thereafter. The adoption of the ASU is not expected to have a significant impact on our financial condition or result of operations.
FASB ASU 2014-04, **Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (Topic 310-40**), was issued to define the term in substance a repossession or foreclosure and physical possession in accounting literature and when a creditor should derecognize the loan receivable and recognize the real estate property. The amendments in this update are intended to reduce diversity in practice by clarifying when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. The amendment is effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The adoption of FASB ASU 2014-04 is not expected to have a significant impact on our financial condition or result of operations.
FASB ASU 2014-01, *Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the Emerging Issues Task Force)*, was issued to permit a reporting entity to make an accounting policy election to account for investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. The amendments are expected to enable more entities to record the amortization of the investment in income tax expense together with the tax credits and other tax benefits generated from the partnership. The ASU is effective retrospectively for public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. For all entities other than public business entities, the amendments are effective retrospectively for annual periods beginning after December 15, 2014, and interim periods within annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company adopted the ASU effective April 1, 2014. See “Note 3 — Accounting for Investment in Qualified Affordable Housing Projects.” for further details.

Acquisition

Acquisition	12 Months Ended

Business Combinations [Abstract]
Acquisition	Note 2 — Acquisition
	Acquisition of Central Bancorp, Inc.
	On August 31, 2014, Hanmi Financial completed its acquisition of CBI, the parent company of United Central Bank (“UCB”). In the merger with CBI, each share of CBI common stock was exchanged for $17.64 per share or $50 million in the aggregate. In addition, Hanmi Financial paid $28.7 million to redeem CBI preferred stock immediately prior to the consummation of the merger. The merger consideration was funded from consolidated cash of Hanmi Financial. At August 31, 2014, CBI had total assets, liabilities and equity of $1.27 billion, $1.17 billion and $93.3 million, respectively. Total loans and deposits were $297.3 million and $1.1 billion, respectively, at August 31, 2014.
	CBI was headquartered in Garland, Texas and through UCB, operated 23 branch locations within Texas, Illinois, Virginia, New York, New Jersey and California. The combined companies operate as Hanmi Financial Corporation and Hanmi Bank, respectively, with banking operations under the Hanmi Bank brand. Following the acquisition, Hanmi Bank has expanded its geographic presence through a network of 49 branches located throughout the United States. Key strategic benefits of the merger include 1) access to highly attractive markets with large Asian-American communities, creating business opportunities by leveraging Hanmi Bank’s brand and business strategies, 2) ability to realize significant cost savings and operational efficiencies for the combined company, and 3) opportunity to prudently deploy capital at an attractive return for our shareholders.
	The acquisition was accounted for under the acquisition method of accounting pursuant to ASC 805, Business Combinations. The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of acquisition date. The Company made significant estimates and exercised significant judgment in estimating the fair values and accounting for such acquired assets and assumed liabilities. Such fair values are preliminary estimates and are subject to adjustment for up to one year after the acquisition date or when additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. The fair values are based on provisional valuation estimates of the fair values of the acquired assets and assumed liabilities. The valuation of acquired loans, income taxes and the core deposit intangibles are based on a preliminary estimate and are subject to change as the provisional amounts are finalized. Such changes to the preliminary estimates during the measurement period are recorded as retrospective adjustments to the consolidated financial statements. During the measurement period, the Company identified retrospective adjustments to certain of the provisional amounts recorded that had the net effect of increasing the bargain purchase gain, net of deferred taxes by $8.0 million.

	The following table presents the purchase price allocation reported as of the acquisition date, the retrospective adjustments recorded during the measurement period and the purchase price allocation as remeasured as of the acquisition date:

	The provisional application of the acquisition method of accounting resulted in a bargain purchase gain of $14.6 million. The operations of CBI are included in our operating results since the acquisition date through the year ended December 31, 2014. Acquisition-related costs of $6.6 million for the year ended December 31, 2014 were expensed as incurred as merger and integration costs. These expenses are comprised primarily of system conversion costs and professional fees. The $297.3 million estimated fair value of loans acquired from CBI was determined by utilizing a discounted cash flow methodology considering credit and interest rate risk. Cash flows were determined by estimating future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value based on a current market rate for similar loans. There was no carryover of CBI’s allowance for loan losses associated with the loans acquired as loans were initially recorded at fair value.
	The following table summarizes the accretable yield on the PCI loans acquired from the CBI merger at August 31, 2014.


			(In thousands)
	Undiscounted contractual cash flows		$	93,623
	Nonaccretable discount			(17,421	)

	Undiscounted cash flow to be collected			76,202
	Estimated fair value of PCI loans			65,346

	Accretable yield		$	10,856


	The core deposit intangible (“CDI”) of $2.2 million was recognized for the core deposits acquired from CBI. The CDI is amortized over its useful life of approximately ten years on an accelerated basis and reviewed for impairment at least quarterly. The amortization expense for the year ended December 31, 2014 was $133,000.
	The fair value of savings and transactional deposit accounts was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. Expected cash flows were utilized for the fair value calculation of the certificates of deposit based on the contractual terms of the certificates of deposit and the cash flows were discounted based on a current market rate for certificates of deposit with corresponding maturities. The premium for certificates of deposit was $11.3 million with $2.3 million amortized for year ended December 31, 2014.
	The fair value of subordinated debentures was determined by estimating projected future cash flows and discounting them at a market rate of interest. A discount of $8.3 million was recognized for subordinated debentures, which will be amortized over their contractual term. The amortization for the year ended December 31, 2014 was $71,000.
	Unaudited Pro Forma Results of Operations
The following table presents our unaudited pro forma results of operations for the periods presented as if the CBI acquisition had been completed on January 1, 2013. The unaudited pro forma results of operations include the historical accounts of Hanmi Financial and CBI and pro forma adjustments as may be required, including the amortization of intangibles with definite lives and the amortization or accretion of any premiums or discounts arising from fair value adjustments for assets acquired and liabilities assumed.

Accounting for Investments in Qualified Affordable Housing Projects	12 Months Ended

Accounting Changes and Error Corrections [Abstract]
Accounting for Investments in Qualified Affordable Housing Projects	Note 3 — Accounting for Investments in Qualified Affordable Housing Projects
	The Bank invests in qualified affordable housing projects (low income housing) and previously accounted for them under the equity method of accounting. The Bank recognized its share of partnership losses in other operating expenses with the tax benefits recognized in the income tax provision. In January 2014, the FASB issued ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects, which amends ASC 323 to provide the ability to elect the proportional amortization method with the amortization expense and tax benefits recognized through the income tax provision. This ASU is effective for the annual period beginning after December 15, 2014, with early adoption being permitted. The Bank elected to early adopt the provisions of the ASU in the second quarter of 2014 and elected the proportional amortization method as retrospective transition. This accounting change in the amortization methodology resulted in changes to account for amortization recognized in prior periods, which impacted the balance of tax credit investments and related tax accounts. The investment amortization expense is presented as a component of the income tax provision.
	The cumulative effect of the retrospective application of this accounting principle as of January 1, 2012 was a negative $1.1 million. Net incomes for the years ended December 31, 2014 and 2013 decreased by $49,000 and $50,000, respectively, due to the change in accounting principle.

	The following tables present the effect of the retrospective application of this change in accounting principle on the Company’s Consolidated Balance Sheets, Statements of Income and Statement of Cash Flows for the respective periods:

The Bank determined that there were no events or changes in circumstances indicating that it is more likely than not that the carrying amount of the investment will not be realized. Therefore, no impairment was recognized as of December 31, 2014 or December 31, 2013. The investment in low income housing was $21.3 million and $3.0 million as of December, 2014 and 2013, respectively. The Bank’s unfunded commitments related to low income housing investments was $11.9 million as of December 31, 2014 and there were none as of December 31, 2013.

Discontinued Operations and Disposal Groups [Abstract]
Sale of Insurance Subsidiaries and Discontinued Operations	Note 4 — Sale of Insurance Subsidiaries and Discontinued Operations
	In June 2014, Hanmi Financial sold its insurance subsidiaries, Chun-Ha and All World, and entered into a stock purchase agreement for their sale. The subsidiaries were classified as held for sale in April 2014 and accounted for as discontinued operations. The operations and cash flows of the businesses have been eliminated and in accordance with the provisions of ASC 205, Presentation of Financial Statements, the results are reported as discontinued operations for all periods presented.
	Hanmi Financial completed the sale of its two insurance subsidiaries to Chunha Holding Corporation on June 30, 2014 when total assets and net assets of Chun-Ha and All World were $5.6 million and $3.3 million as of June 30, 2014, respectively. The total sales price was $3.5 million, of which $2.0 million was paid upon signing. The $2.0 million was reduced by $1.6 million cash and cash equivalents included in net assets of Chun-Ha and All World, resulting in $398,000 net cash proceeds. The remaining $1.5 million will be payable in three equal installments on each anniversary of the closing date through June 30, 2017.
	The sale resulted in a $51,000 gain, offset by a $470,000 capital gain tax, a $14,000 operating losses and an $11,000 income tax expense. Consequently, the net loss from discontinued operations for the year ended December 31, 2014 was $444,000, or $0.01 per diluted share. For the year ended December 31, 2014, the discontinued operations generated noninterest income, primarily in the line item for insurance commissions, of $2.7 million and incurred noninterest expense of $2.7 million in various line items.

All individual securities that have been in a continuous unrealized loss position for 12 months or longer as of December 31, 2014 and December 31, 2013 had investment grade ratings upon purchase. The issuers of these securities have not established any cause for default on these securities and the various rating agencies have reaffirmed these securities’ long-term investment grade status as of December 31, 2014 and December 31, 2013. These securities have fluctuated in value since their purchase dates as market interest rates have fluctuated.
FASB ASC 320 requires other-than-temporarily impaired investment securities to be written down when fair value is below amortized cost in circumstances where: (1) an entity has the intent to sell a security; (2) it is more likely than not that an entity will be required to sell the security before recovery of its amortized cost basis; or (3) an entity does not expect to recover the entire amortized cost basis of the security. If an entity intends to sell a security or if it is more likely than not the entity will be required to sell the security before recovery, an OTTI write-down is recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value. If an entity does not intend to sell the security or it is not more likely than not that it will be required to sell the security before recovery, the OTTI write-down is separated into an amount representing credit loss, which is recognized in earnings, and the amount related to all other factors, which is recognized in other comprehensive income.

The Company does not intend to sell these securities and it is more likely than not that we will not be required to sell the investments before the recovery of its amortized cost basis. In addition, the unrealized losses on municipal and corporate bonds are not considered other-than-temporarily impaired, as the bonds are rated investment grade and there are no credit quality concerns with the issuers. Interest payments have been made as scheduled, and management believes this will continue in the future and that the bonds will be repaid in full as scheduled. Therefore, in management’s opinion, all securities that have been in a continuous unrealized loss position for the past 12 months or longer as of December 31, 2014 and December 31, 2013 were not other-than-temporarily impaired, and therefore, no impairment charges as of December 31, 2014 and December 31, 2013 were warranted.
Realized gains and losses on sales of investment securities and proceeds from sales of investment securities were as follows for the periods indicated:


		Year Ended December 31,
		2014			2013			2012
Gross realized gains on sales of investment securities		$	2,012		$	1,602		$	1,447
Gross realized losses on sales of investment securities			(1	)		(563	)		(51	)

Proceeds from sales of investment securities		$	169,533		$	78,473		$	102,538
For the year ended December 31, 2014, there was a $2.0 million net gain in earnings resulting from the redemption and sale of investment securities that had previously been recognized as net unrealized losses of $498,000 in comprehensive income. For the year ended December 31, 2013, there was a $1.0 million net gain in earnings resulting from the redemption and sale of investment securities that had previously been recorded as net unrealized gains of $3.3 million in comprehensive income.
Investment securities available for sale with market values of $76.2 million and $47.6 million as of December 31, 2014 and 2013, respectively, were pledged to secure FHLB advances, public deposits and for other purposes as required or permitted by law.

Loans	Note 6 — Loans
	The Board of Directors and management review and approve the Bank’s loan policy and procedures on a regular basis to reflect issues such as regulatory and organizational structure changes, strategic planning revisions, concentrations of credit, loan delinquencies and nonperforming loans, problem loans, and policy adjustments.
	Real estate loans are loans secured by liens or interest in real estate, to provide purchase, construction, and refinance on real estate properties. Commercial and industrial loans consist of commercial term loans, commercial lines of credit, and Small Business Administration (“SBA”) loans. Consumer loans consist of auto loans, credit cards, personal loans, and home equity lines of credit. We maintain management loan review and monitoring departments that review and monitor pass graded loans as well as problem loans to prevent further deterioration.
	Concentrations of Credit: The majority of the Bank’s loan portfolio consists of commercial real estate and commercial and industrial loans.

The allowance for off-balance sheet items is maintained at a level believed to be sufficient to absorb probable losses related to these unfunded credit facilities. The determination of the allowance adequacy 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, 2014 and 2013, the allowance for off-balance sheet items amounted $1.4 million and $1.2 million, respectively. Net adjustments to the allowance for off-balance sheet items are included in the provision for credit losses.

Credit Quality Indicators
As part of the on-going monitoring of the credit quality of our loan portfolio, we utilize an internal loan grading system to identify credit risk and assign an appropriate grade (from (0) to (8)) for each and every loan in our loan portfolio. A third-party loan review is required on an annual basis. Additional adjustments are made when determined to be necessary. The loan grade definitions are as follows:
Pass and Pass-Watch: Pass and Pass-Watch loans, grades (0-4), are in compliance with the Bank’s credit policy and regulatory requirements, and do not exhibit any potential or defined weaknesses as defined under “Special Mention,” “Substandard” or “Doubtful.” This category is the strongest level of the Bank’s loan grading system. It consists of all performing loans with no identified credit weaknesses. It includes cash and stock/security secured loans or other investment grade loans.
Special Mention: A Special Mention credit, grade (5), has potential weaknesses that deserve management’s close attention. If not corrected, these potential weaknesses may result in deterioration of the repayment of the debt and result in a Substandard classification. Loans that have significant actual, not potential, weaknesses are considered more severely classified.
Substandard: A Substandard credit, grade (6), has a well-defined weakness that jeopardizes the liquidation of the debt. A credit graded Substandard is not protected by the sound worth and paying capacity of the borrower, or of the value and type of collateral pledged. With a Substandard loan, there is a distinct possibility that the Bank will sustain some loss if the weaknesses or deficiencies are not corrected.

Doubtful: A Doubtful credit, grade (7), is one that has critical weaknesses that would make the collection or liquidation of the full amount due improbable. However, there may be pending events which may work to strengthen the credit, and therefore the amount or timing of a possible loss cannot be determined at the current time.
Loss: A loan classified as Loss, grade (8), is considered uncollectible and of such little value that their continuance as active bank assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this asset even though partial recovery may be possible in the future. Loans classified as Loss will be charged off in a timely manner.

Impaired Loans
Loans are considered impaired when nonaccrual and principal or interest payments have been contractually past due for 90 days or more, unless the loan is both well-collateralized and in the process of collection; or they are classified as TDR loans to offer terms not typically granted by the Bank; or when current information or events make it unlikely to collect in full according to the contractual terms of the loan agreements; or there is a deterioration in the borrower’s financial condition that raises uncertainty as to timely collection of either principal or interest; or full payment of both interest and principal is in doubt according to the original contractual terms.
We evaluate loan impairment in accordance with applicable GAAP. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as a practical 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, the deficiency will be charged off against the allowance for loan losses or, alternatively, a specific allocation will be established. Additionally, loans that are considered impaired are specifically excluded from the quarterly migration analysis when determining the amount of the allowance for loan losses required for the period.
The allowance for collateral-dependent loans is determined by calculating the difference between the outstanding loan balance and the value of the collateral as determined by recent appraisals. The allowance for collateral-dependent loans varies from loan to loan based on the collateral coverage of the loan at the time of designation as nonperforming. We continue to monitor the collateral coverage, using recent appraisals, on these loans on a quarterly basis and adjust the allowance accordingly.

There were no commitments to lend additional funds to borrowers whose loans are included above.

Nonaccrual Loans
Loans are placed on nonaccrual status when, in the opinion of management, the full timely collection of principal or interest is in doubt. Generally, the accrual of interest is discontinued when principal or interest payments become more than 90 days past due, unless management believes the loan is adequately collateralized and in the process of collection. However, in certain instances, we may place a particular loan on nonaccrual status earlier, depending upon the individual circumstances surrounding the loan’s delinquency. When a loan is placed on nonaccrual status, previously accrued but unpaid interest is reversed against current income. Subsequent collections of cash are applied as principal reductions when received, except when the ultimate collectability of principal is probable, in which case interest payments are credited to income. Nonaccrual loans may be restored to accrual status when principal and interest payments become current and full repayment is expected.

Of the $15.8 million, $15.3 million were OREOs as loans acquired in the CBI acquisition that were foreclosed subsequent to the acquisition date. As of December 31, 2013, there were three OREOs with a combined carrying value of $756,000 and a valuation adjustment of $56,000.
Troubled Debt Restructuring
In April 2011, the FASB issued ASU 2011-02, “A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring,” which clarifies the guidance for evaluating whether a restructuring constitutes a TDR. This guidance is effective for the first interim or annual period beginning on or after June 15, 2011, and should be applied retrospectively to the beginning of the annual period of adoption. For the purposes of measuring impairment of loans that are newly considered impaired, the guidance should be applied prospectively for the first interim or annual period beginning on or after June 15, 2011.

As a result of the amendments in ASU 2011-02, we reassessed all restructurings that occurred on or after the beginning of the annual period and identified certain receivables as TDRs. Upon identifying those receivables as TDRs, we considered them impaired and applied the impairment measurement guidance prospectively for those receivables newly identified as impaired.
The following table details TDRs (excluding PCI loans), disaggregated by concession type and by loan type, as of December 31, 2014, 2013 and 2012:

As of December 31, 2014, 2013 and 2012, total TDRs, excluding loans held for sale, were $26.3 million, $30.0 million and $35.7 million, respectively. A debt restructuring is considered a TDR if we grant a concession that we would not have otherwise considered to the borrower, for economic or legal reasons related to the borrower’s financial difficulties. Loans are considered to be TDRs if they were restructured through payment structure modifications such as reducing the amount of principal and interest due monthly and/or allowing for interest only monthly payments for six months or less. All TDRs are impaired and are individually evaluated for specific impairment using one of these three criteria: (1) the present value of expected future cash flows discounted at the loan’s effective interest rate; (2) the loan’s observable market price; or (3) the fair value of the collateral if the loan is collateral dependent.
At December 31, 2014, 2013 and 2012, TDRs, excluding loans held for sale, were subjected to specific impairment analysis, and $2.9 million, $2.8 million and $3.6 million, respectively, of reserves relating to these loans were included in the allowance for loan losses.

During the year ended December 31, 2014, we restructured monthly payments on 17 loans, with a net carrying value of $9.8 million as of December 31, 2014, through temporary payment structure modifications or re-amortization. For the restructured loans on accrual status, we determined that, based on the financial capabilities of the borrowers at the time of the loan restructuring and the borrowers’ past performance in the payment of debt service under the previous loan terms, performance and collection under the revised terms are probable.

Loans accounted for as PCI are generally considered accruing and performing loans as the accretable discount is accreted to interest income over the estimated life of the loan when cash flows are reasonably estimable. Accordingly, PCI loans that are contractually past due are still considered to be accruing and performing loans. If the timing and amount of future cash flows is not reasonably estimable, the loans are classified as nonaccrual loans and interest income is not recognized until the timing and amount of future cash flows can be reasonably estimated. As of December 31, 2014, we had no PCI loans on nonaccrual status and included in the delinquency table below.

At December 31, 2014 and 2013, we serviced loans sold to unaffiliated parties in the amounts of $500.9 million and $350.0 million, respectively. These represented loans that have been sold for which the Bank continues to provide servicing. These loans are maintained off balance sheet and are not included in the loans receivable balance. All of the loans being serviced were SBA loans.
FDIC Loss Sharing Asset & Liability
The FDIC loss sharing asset related to the assumption of Single Family and Commercial Shared-Loss Agreement (“SLAs”) between CBI and the FDIC arising from the CBI’s acquisition of Mutual Bank. The loss sharing asset was measured at its fair value as of August 31, 2014 in conjunction with the acquisition of CBI. During the third quarter of 2014, the Bank submitted losses in excess of the stated reimbursement threshold of $611.0 million, increasing the reimbursable percentage to 95 from 80. The three-year recovery period on the Commercial Share-Loss Portfolio commenced on October 1, 2014. During this period, 95 percent of any recoveries of previously charged-off and reimbursed Commercial SLA loans need to be reimbursed to the FDIC, less any reasonable recovery costs incurred. As of December 31, 2014, the FDIC loss sharing liability was related to $2.1 million net payables to the FDIC, consisting of $3.3 million of the FDIC recoveries partially offset by $1.2 million of reimbursable expense owed to the Bank. Of the $2.1 million net payable to the FDIC, $102,000 was related to the Single Family SLA Portfolio.

	Subordinated Debentures
	During the third quarter of 2014, the Company assumed CBI’s Junior Subordinated Deferrable Interest Debentures (“Subordinated Debentures”) with an unpaid principal balance of $26.8 million and an estimated fair value of $18.5 million. The $8.3 million discount will be amortized to interest expense over the remaining term. In December 2005, a trust was formed by CBI and issued $26.0 million Trust Preferred Securities (“TPS”) at 6.26 percent fixed rate for the first five years and a variable rate at the 3 month LIBOR plus 140 basis thereafter and invested the proceeds in Subordinated Debentures. The Subordinated Debentures will mature on December 31, 2035, however, the Bank may redeem the Subordinated Debentures at an earlier date if certain conditions are met. The TPS will be subject to mandatory redemption if the Subordinated Debentures are repaid by the Company. Interest is payable quarterly, and the Company has the option to defer interest payments on the Subordinated Debentures from time to time for a period not to exceed five consecutive years. The discount amortization was $71,000 for the year ended December 31, 2014.
	Rescinded Stock Obligation
	Hanmi Financial assumed a rescinded stock obligation of $15.5 million and related accrued interest payable of $4.5 million at the closing date. The obligation resulted from the issuance of CBI common shares that CBI was not legally authorized to issue in 2010 and 2009. Interest has been accrued on the obligation statutory at interest rates that vary from state to state. Hanmi Financial paid off $14.8 million of the obligation and $87,000 of interest expense was recorded for the year ended December 31, 2014, reflecting a weighted average rate of 6.79%. Rescinded stock obligation and accrued interest as of December 31, 2014 were $933,000 and $288,000, respectively.

Income Taxes	Note 12 — Income Taxes
	In accordance with the provisions of FASB ASC 740, the Company periodically reviews its income tax positions based on tax laws and regulations and financial reporting considerations, and records adjustments as appropriate. This review takes into consideration the status of current taxing authorities’ examinations of the Company’s tax returns, recent positions taken by the taxing authorities on similar transactions, if any, and the overall tax environment.
	A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:


			Year Ended December 31,
			2014				2013				2012
			(In thousands)
	Unrecognized tax benefits at beginning of year		$	1,254			$	1,254			$	1,281

	Lapse of statute of limitations			—				—				(41	)

	Unrecognized tax benefits at end of year		$	1,765			$	1,254			$	1,254


	The total amount of unrecognized tax benefits that would affect our effective tax rate if recognized was $1.5 million, $1.0 million and $1.0 million as of December 31, 2014, 2013 and 2012, respectively.
	For the year ended December 31, 2014, unrecognized tax benefits increased by $676,000 related to California Enterprise Zone interest deduction, offset by a $165,000 decrease in connection with the tax position taken on expense related to non-qualified stock option. For the year ended December 31, 2013, there was no addition in unrecognized tax benefit except increases in accrued interest. For the year ended December 31, 2012, unrecognized tax benefits decreased by $27,000 in connection with the tax position taken on expense related to prior business acquisition cost.
	In 2014, 2013 and 2012, the Company accrued interest of $52,000, $45,000 and $41,000 for uncertain tax benefits, respectively. As of December 31, 2014, 2013 and 2012, the total amounts of accrued interest related to uncertain tax positions were $366,000, $403,000 and $360,000, respectively. We account for interest and penalties related to uncertain tax positions as part of our provision for federal and state income taxes. Accrued interest and penalties are included within the related tax liability line on the Consolidated Balance Sheets.
	Unrecognized tax benefits primarily include state exposures from California Enterprise Zone interest deductions and income tax treatment for prior business acquisition costs, and dividend income from FRB stock. We believe that it is reasonably possible that certain remaining unrecognized tax positions, each of which are individually insignificant, may be recognized by the end of 2015 because of a lapse of the statute of limitations. We do not anticipate any material change in the total amount of unrecognized tax benefits to occur within the next twelve months.
	As of December 31, 2014, the Company was subject to examination by various federal and state tax authorities for the years ended December 31, 2004 through 2013. As of December 31, 2014, the Company was subjected to audit or examination by Internal Revenue Service for the 2009 tax year and California FTB for the 2008 and 2009 tax years. Management does not anticipate any material changes in our financial statements due to the result of the audits.

Net deferred tax assets		$	70,150			$	51,888			$	51,069

As of December 31, 2014 net deferred tax assets, which were primarily the results of allowance for loan losses and net operating loss carryforwards, increased by $18.3 million due mainly to the acquisition of CBI. As of December 31, 2013, the Company’s net deferred tax assets were primarily the result of net operating loss carryforwards, allowance for loan losses and unrealized loss on securities available for sale. For the year ended December 31, 2012, the Company recorded a net valuation allowance release of $62.6 million based on management’s reassessment of the amount of its deferred tax assets that are more likely than not to be realized.
As of each reporting date, management considers the realization of deferred tax assets based on management’s judgment of various future events and uncertainties, including the timing and amount of future income, as well as the implementation of various tax planning strategies to maximize realization of deferred tax assets. A valuation allowance is provided when it is more likely than not that some portion of deferred tax assets will not be realized. As of December 31, 2014, management determined that no valuation allowance for deferred tax assets is required, as management believes it is more likely than not that deferred tax assets will be realized principally through future reversals of existing taxable temporary differences. Management further believes that future taxable income will be sufficient to realize the benefits of temporary deductible differences that cannot be realized through carry-back to prior years or through the reversal of future temporary taxable differences.
As of December 31, 2014, the Company had net operating loss carryforwards of $20.9 million and $245.8 million for federal and state income tax purposes, respectively, which are available to offset future taxable income, if any, through 2033.

	Stock Warrants
	As part of an agreement dated as of July 27, 2010 with Cappello Capital Corp., the placement agent in connection with our best efforts offering and the financial advisor in connection with our completed rights offering, we issued warrants to purchase 250,000 shares of our common stock for services performed. The warrants have an exercise price of $9.60 per share. According to the agreement, the warrants vested on October 14, 2010 and are exercisable until their expiration on October 14, 2015. The Company followed the guidance of FASB ASC Topic 815-40, Derivatives and Hedging—Contracts in Entity’s Own Stock, which established a framework for determining whether certain freestanding and embedded instruments are indexed to a company’s own stock for purposes of evaluation of the accounting for such instruments under existing accounting literature. Under GAAP, the issuer is required to measure the fair value of the equity instruments in the transaction as of the earlier of (i) the date at which a commitment for performance by the counterparty to earn the equity instruments is reached or (ii) the date at which the counterparty’s performance is complete. The fair value of the warrants at the date of issuance totaling $2.0 million was recorded as a liability and a cost of equity, which was determined by the Black-Scholes option pricing model. The expected stock volatility was based on historical volatility of our common stock over the expected term of the warrants. We used a weighted average expected stock volatility of 111.46 percent. The expected life assumption was based on the contract term of five years. The dividend yield of zero was based on the fact that we had no intention to pay cash dividends for the term at the grant date. The risk free rate of 2.07 percent used for the warrants was equal to the zero coupon rate in effect at the time of the grant. During the year ended December 31, 2014, the remaining stock warrants were exercised and there were no outstanding stock warrants as of December 31, 2014. The fair value of stock warrants was $2,000 at December 31, 2013.

In addition to the risk-based guidelines, federal bank regulatory agencies require bank holding companies and banks to maintain a minimum ratio of Tier 1 capital to average assets, referred to as the leverage ratio, of 4.0 percent.
	In order for banks to be considered “well capitalized,” federal bank regulatory agencies require them to maintain a minimum ratio of qualifying total capital to risk-weighted assets of 10.0 percent and a minimum ratio of Tier 1 capital to risk-weighted assets of 6.0 percent. In addition to the risk-based guidelines, federal bank regulatory agencies require depository institutions to maintain a minimum ratio of Tier 1 capital to average assets, referred to as the leverage ratio, of 5.0 percent.

	Regulatory Capital Rule Adjustments
	In July 2013, the Board of Governors of the Federal Reserve System, the Office of the Comptroller of the Currency and the Federal Deposit Insurance Corporation approved the Basel III regulatory capital framework and related Dodd-Frank Wall Street Reform and Consumer Protection Act changes. The rules revise minimum capital requirements and adjust prompt corrective action thresholds. The rules also revise the regulatory capital elements, add a new common equity Tier I capital ratio, and increase the minimum Tier I capital ratio requirement. The revisions permit banking organizations to retain, through a one-time election, the existing treatment for accumulated other comprehensive income. Additionally, the rules implement a new capital conservation buffer. Under the final rules, institutions are subject to limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses if its capital level falls below the capital conservation buffer amount. The rules became effective January 1, 2015 for smaller, non-complex banking organizations with full implementation of the capital conservation buffer and certain deductions and adjustments to regulatory capital through January 1, 2019. The Company will continue to evaluate the new changes, and expects that the Company and the Bank will meet the capital requirements.

Fair Value Measurements	Dec. 31, 2014
Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 16 — Fair Value Measurements
	Fair Value Measurements
	FASB ASC 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value including a three-level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The three-level fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value are defined as follows:

		•		Level 1 - Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

		•		Level 2 - Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data.

		•		Level 3 - Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.
	Fair value is used on a recurring basis for certain assets and liabilities in which fair value is the primary basis of accounting. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment or for disclosure purposes.
	We record investment securities available for sale at fair value on a recurring basis. Certain other assets, such as loans held for sale, impaired loans, other real estate owned, and other intangible assets, are recorded at fair value on a non-recurring basis. Non-recurring 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 re-measurement is performed.
	The following methods and assumptions were used to estimate the fair value of each class of financial instrument below:
	Investment securities available for sale – The fair values of investment securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges. If quoted prices are not available, fair values are measured using matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities, or other model-based valuation techniques requiring observable inputs other than quoted prices such as yield curve, prepayment speeds, and default rates. Level 1 investment securities include U.S. government and agency debentures and equity securities that are traded on an active exchange or by dealers or brokers in active over-the-counter markets. The fair value of these securities is determined by quoted prices on an active exchange or over-the-counter market. Level 2 investment securities primarily include mortgage-backed securities, municipal bonds, collateralized mortgage obligations, SBA loan pool securities, and equity securities in markets that are not active. In determining the fair value of the securities categorized as Level 2, we obtain reports from nationally recognized broker-dealers detailing the fair value of each investment security held as of each reporting date. The broker-dealers use prices obtained from nationally recognized pricing services to value our fixed income securities. The fair value of the municipal bonds is determined based on a proprietary model maintained by the broker-dealers. We review the prices obtained for reasonableness based on our understanding of the marketplace, and also consider any credit issues related to the bonds. As we have not made any adjustments to the market quotes provided to us and as they are based on observable market data, they have been categorized as Level 2 within the fair value hierarchy. Level 3 investment securities are instruments that are not traded in the market. As such, no observable market data for the instrument is available, which necessitates the use of significant unobservable inputs.
	As of December 31, 2014, we had a zero coupon tax credit municipal bond of $709,000 compared to $748,000 as of December 31, 2013. This bond was recorded at estimated fair value using a discounted cash flow method, and was measured on a recurring basis with Level 3 inputs. Key assumptions used in measuring the fair value of the tax credit bond as of December 31, 2014 were discount rate and cash flows. The discount rate was derived from the term structure of Bank Qualified (“BQ”) “BBB-” rated municipal bonds, as the tax credit bond’s guarantee had the similar credit strength. The contractual future cash flows were the tax credits to be received for a remaining life of 0.23 year. We do not anticipate a significant deterioration of the tax credit bond’s credit quality. Management reviews the discount rate on an ongoing basis based on current market rates.

	SBA loans held for sale – SBA loans held for sale are carried at the lower of cost or fair value. As of December 31, 2014 and December 31, 2013, we had $5.5 million and no SBA loans held for sale, respectively. Management obtains quotes, bids or pricing indication sheets on all or part of these loans directly from the purchasing financial institutions. Premiums received or to be received on the quotes, bids or pricing indication sheets are indicative of the fact that cost is lower than fair value. At December 31, 2014, the entire balance of SBA loans held for sale was recorded at its cost. We record SBA loans held for sale on a nonrecurring basis with Level 2 inputs.
	Impaired loans (excluding PCI loans) – Nonaccrual loans and performing restructured loans are considered impaired for reporting purposes and are measured and recorded at fair value on a non-recurring basis. Nonaccrual Non-PCI loans with an unpaid principal balance over $100,000 and all performing restructured loans are reviewed individually for the amount of impairment, if any. Nonaccrual Non-PCI loans with an unpaid principal balance of $100,000 or less are evaluated for impairment collectively. The Company does not record loans at fair value on a recurring basis. However, from time to time, nonrecurring fair value adjustments to collateral dependent impaired loans are recorded based on either the current appraised value of the collateral, a Level 2 measurement, or management’s judgment and estimation of value reported on older appraisals that are then adjusted based on recent market trends, a Level 3 measurement.
	Other real estate owned – Fair value of OREO is based primarily on third party appraisals, less costs to sell and result in a Level 2 classification of the inputs for determining fair value. Appraisals are required annually and may be updated more frequently as circumstances require and the fair value adjustments are made to OREO based on the updated appraised value of the property.
	Nonperforming loans held for sale – We reclassify certain nonperforming loans as held for sale when we decide to sell those loans. The fair value of nonperforming loans held for sale is generally based upon the quotes, bids or sales contract prices which approximate their fair value. Nonperforming loans held for sale are recorded at estimated fair value less anticipated liquidation cost. As of December 31, 2014 and 2013, we did not have nonperforming loans held for sale, which are measured on a nonrecurring basis with Level 2 inputs.
	Stock warrants – The Company followed the guidance of FASB ASC Topic 815-40, Derivatives and Hedging—Contracts in Entity’s Own Stock, which establishes a framework for determining whether certain freestanding and embedded instruments are indexed to a company’s own stock for purposes of evaluation of the accounting for such instruments under existing accounting literature. Under GAAP, the issuer is required to measure the fair value of the equity instruments in the transaction as of earlier of (i) the date at which a commitment for performance by the counterparty to earn the equity instruments is reached or (ii) the date at which the counterparty’s performance is complete. The fair value of the warrants was recorded as a liability and a cost of equity, which was determined by the Black-Scholes option pricing modeling and was measured on a recurring basis with Level 3 inputs.

	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	There were no transfers of assets between Level 1 and Level 2 of the fair value hierarchy for the year ended December 31, 2014. As of December 31, 2014 and 2013, assets and liabilities measured at fair value on a recurring basis are as follows:

(1)	Reflects a zero coupon tax credit municipal bond. As the Company was not able to obtain a price from independent external pricing service providers, the discounted cash flow method was used to determine its fair value. The bond carried a par value of $700,000 and an amortized value of $700,000 with a remaining life of 0.23 years at December 31, 2014.
(2)	Reflects two equity securities that are not actively traded. The fair value of one equity security with a fair value of $214,000 was computed using valuation multiples (price to book and price to earnings) derived from market transactions for comparable companies. The other equity security with a fair value of $200,000 was computed using valuation multiples (price to book and price to earnings) derived from 1) market transactions for comparable companies, and 2) publicly-traded comparable companies.
(3)	Reflects warrants for our common stock issued in connection with services Cappello Capital Corp. provided to us as a placement agent in connection with our best efforts public offering and as our financial adviser in connection with our completed rights offering. The warrants were immediately exercisable when issued at an exercise price of $9.60 per share of our common stock and expire on October 14, 2015. As of December 31, 2014, there were no outstanding stock warrants. See “Note 13 – Stockholders’ Equity” for more details.

FASB ASC 825 requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured on a recurring basis or non-recurring basis are discussed above.
The estimated fair value of financial instruments has been determined by using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret market data in order to develop estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that we could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.
The estimated fair values of financial instruments were as follows:

The methods and assumptions used to estimate the fair value of each class of financial instruments for which it was practicable to estimate that value are explained below:
Cash and cash equivalents – The carrying amounts of cash and cash equivalents approximate fair value due to the short-term nature of these instruments (Level 1).

Investment securities – The fair value of investment securities, consisting of investment securities available for sale, is generally obtained from market bids for similar or identical securities, from independent securities brokers or dealers, or from other model-based valuation techniques described above (Level 1, 2 and 3).
Loans receivable, net of allowance for loan losses – Loans receivable include Non-PCI loans, PCI loans and Non-PCI impaired loans. The fair value of Non-PCI loans receivable is estimated based on the discounted cash flow approach. The discount rate was derived from the associated yield curve plus spreads and reflects the offering rates offered by the Bank for loans with similar financial characteristics. Yield curves are constructed by product type using the Bank’s loan pricing model for like-quality credits. The discount rates used in the Bank’s model represent the rates the Bank would offer to current borrowers for like-quality credits. These rates could be different from what other financial institutions could offer for these loans. No adjustments have been made for changes in credit within the loan portfolio. It is our opinion that the allowance for loan losses relating to performing and nonperforming loans results in a fair valuation of such loans. Additionally, the fair value of our loans may differ significantly from the values that would have been used had a ready market existed for such loans and may differ materially from the values that we may ultimately realize (Level 3).
The fair value of PCI loans receivable was estimated based on discounted expected cash flows. Increases in expected cash flows and improvements in the timing of cash flows over those previously estimated increase the amount of accretable yield and are recognized as an increase in yield and interest income prospectively. Decreases in the amount and delays in the timing of expected cash flows compared to those previously estimated decrease the amount of accretable yield and usually result in a provision for loan losses and the establishment of an allowance for loan losses (Level 3).
The fair value of impaired loans (excluding PCI loans) is estimated based on the net realizable fair value of the collateral or the observable market price of the most recent sale or quoted price from loans held for sale. The Company does not record loans at fair value on a recurring basis. Nonrecurring fair value adjustments to collateral dependent impaired loans are recorded based on the current appraised value of the collateral (Level 3).
Loans held for sale – Loans held for sale are carried at the lower of aggregate cost or fair market value, as determined based upon quotes, bids or sales contract prices, or as may be assessed based upon the fair value of the collateral which is obtained from recent real estate appraisals (Level 2). Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustment is typically significant and results in Level 3 classification of the inputs for determining fair value.
Accrued interest receivable – The carrying amount of accrued interest receivable approximates its fair value (Level 1).
Servicing assets or servicing liabilities – Servicing assets or servicing liabilities are carried at its implied fair value. The fair values of the servicing assets or servicing liabilities are estimated by discounting future cash flows using market-based discount rates and prepayments speeds. The discount rate is based on the current U.S. Treasury yield curve, as published by the Department of the Treasury, plus a spread for the marketplace risk associated with these assets. (Level 3)
Investment in Federal Home Loan Bank and Federal Reserve Bank stock – The carrying amounts of investment in FHLB and FRB stock approximate fair value as such stock may be resold to the issuer at carrying value (Level 1).
Noninterest-bearing deposits – The fair value of noninterest-bearing deposits is the amount payable on demand at the reporting date (Level 2).
Interest-bearing deposits – The fair value of interest-bearing deposits, such as savings accounts, money market checking, and certificates of deposit, is estimated based on discounted cash flows. The cash flows for non-maturity deposits, including savings accounts and money market checking, are estimated based on their historical decaying experiences. The discount rate used for fair valuation is based on interest rates currently being offered by the Bank on comparable deposits as to amount and term (Level 3).
Borrowings – Borrowings consist of FHLB advances, subordinated debentures and other borrowings. Discounted cash flows based on current market rates for borrowings with similar remaining maturities are used to estimate the fair value of borrowings (Level 3).
Accrued interest payable – The carrying amount of accrued interest payable approximates its fair value (Level 1).
Stock warrants – The fair value of stock warrants is determined by the Black-Scholes option pricing model. The expected stock volatility is based on historical volatility of our common stock over expected term of the warrants. The expected life assumption is based on the contract term and dividend yield is based on the Company’s annual dividend divided by its current share price. The risk free rate used for the warrants is equal to the zero coupon rate in effect at the end of the measurement period (Level 3).

Commitments to extend credit and standby letters of credit – The fair values of commitments to extend credit and standby letters of credit are based upon the difference between the current value of similar loans and the price at which the Bank has committed to make the loans (Level 3).

Share-based Compensation	12 Months Ended
Share-based Compensation	Dec. 31, 2014
Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-based Compensation	Note 17 — Share-based Compensation
	At December 31, 2014, we had three incentive plans, the Year 2000 Stock Option Plan (the “2000 Plan”), the 2007 Equity Compensation Plan (the “2007 Plan”) which replaced the 2000 Plan and the 2013 Equity Compensation Plan (the “2013 Plan” and with the 2000 Plan and 2007 Plan, the “Plans”) which replaced the 2007 Plan.
	The 2013 Plan provides awards of any options, stock appreciation right, restricted stock award, restricted stock unit award, share granted as a bonus or in lieu of another award, dividend equivalent, other stock-based award or performance award, together with any other right or interest to a participant under the plan. Plan participant includes executives and other employees, officers, directors, consultants and other persons who provide services to the Company or its related entities. Although no future stock options may be granted under the 2007 Plan and 2000 Plan, certain employees, directors and officers of Hanmi Financial and its subsidiaries still hold options to purchase Hanmi Financial common stock under the 2013 Plan.
	Under the 2013 Plan, we may grant equity incentive awards for up to 1,500,000 shares of common stock. As of December 31, 2014, 916,043 shares were still available for issuance under the 2013 Plan.
	The table below provides the share-based compensation expense and related tax benefits for the periods indicated:


			Year Ended December 31,

	Share-based compensation expense		$	2,165			$	705			$	478
	Related tax benefits		$	516			$	32			$	201
	As of December 31, 2014, unrecognized share-based compensation expense was as follows:


			Unrecognized				Average Expected

							Period
			(In thousands)
	Stock option awards		$	1,349				1.8 years
	Restricted stock awards			2,609				2.2 years

	Total unrecognized share-based compensation expense		$	3,958				2.1 years

	2013 and 2007 Equity Compensation Plans and 2000 Stock Option Plan
	Stock Options
	All stock options granted under the Plans have an exercise price equal to the fair market value of the underlying common stock on the date of grant. Stock options granted under the Plans generally vest based on three to five years of continuous service and expire 10 years from the date of grant. Certain option and share awards provide for accelerated vesting if there is a change in control (as defined in the Plan). New shares of common stock are issued or treasury shares are utilized upon the exercise of stock options.

	The weighted-average fair value per share of options granted was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:


			Year Ended December 31,
			2014				2013				2012
	Weighted-average assumption
	Dividend yield			1.27	%			1.61	%			—
	Expected volatility			35.18	%			43.67	%			65.23	%
	Expected term			3.0 years				3.0 years				3.0 years
	Risk-free interest rate			0.86	%			0.79	%			0.32	%
	Expected volatility was determined based on the historical weekly volatility of our stock price over a period equal to the expected term of the options granted. The expected term of the options represents the period that options granted are expected to be outstanding based primarily on the historical exercise behavior associated with previous option grants. The risk-free interest rate was based on the U.S. Treasury yield curve at the time of grant for a period equal to the expected term of the options granted.
	The following information under the Plans is presented for the periods indicated:

Restricted stock awards under the Plans become fully vested after three to five years of continued employment from the date of grant. Hanmi Financial becomes entitled to an income tax deduction in an amount equal to the taxable income reported by the holders of the restricted shares when the restrictions are released and the shares are issued. Restricted shares are forfeited if officers and employees terminate prior to the lapsing of restrictions. Forfeitures of restricted stock are treated as cancelled shares.

Earnings Per Share [Abstract]
Earnings per Share	Note 18 — Earnings per Share
	Earnings per share (“EPS”) is calculated on both a basic and a diluted basis. Basic EPS excludes dilution and is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted from the issuance of common stock that then shared in earnings, excluding common shares in treasury. Unvested restricted stock is excluded from the calculation of weighted-average common shares for basic EPS. For diluted EPS, weighted-average common shares include the impact of restricted stock under the treasury method.

	The following table is a reconciliation of the components used to derive basic and diluted EPS for the periods indicated:

	401(k) Plan
	We have a Section 401(k) plan for the benefit of substantially all of our employees. We match 75 percent of participant contributions to the 401(k) plan up to 8 percent of each 401(k) plan participant’s annual compensation. Contributions to the 401(k) plan were $1.3 million, $1.0 million and $1.0 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	Bank-Owned Life Insurance
	In 2001 and 2004, we purchased single premium life insurance policies called bank-owned life insurance covering certain officers. As of December 31, 2014, cash surrender value of BOLI was $48.9 million, of which $18.3 million was acquired in the acquisition of CBI. The Bank is the beneficiary under the policy. In the event of the death of a covered officer, we will receive the specified insurance benefit from the insurance carrier.

	Deferred Compensation Plan
	Effective November 1, 2006, the Board of Directors approved the Hanmi Financial Corporation Deferred Compensation Plan (the “DCP”). The DCP is unfunded, and a non-qualified deferred compensation program for directors and certain key employees whereby they may defer a portion of annual compensation for payment upon retirement of the amount deferred plus a guaranteed return. The liabilities for the deferred compensation plan and interest thereon were zero both as of December 31, 2014 and 2013.

Risks and Uncertainties [Abstract]
Off-Balance Sheet Commitments	Note 21 — Off-Balance Sheet Commitments
	The Bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk similar to the risk involved with on-balance sheet items recognized in the Consolidated Balance Sheets.
	The Bank’s exposure to credit losses in the event of non-performance by the other party to commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for extending loan facilities to customers. The Bank 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, was based on management’s credit evaluation of the counterparty.
	Collateral held varies but may include accounts receivable, inventory, premises and equipment, and income-producing or borrower-occupied properties. The following table shows the distribution of undisbursed loan commitments as of the dates indicated:


		December 31,		December 31,

Liquidity	Note 22 — Liquidity
	Hanmi Financial
	Management believes that Hanmi Financial, on a stand-alone basis, has adequate liquid assets to meet its operating cash needs through December 31, 2015.
	Hanmi Bank
	The principal objective of our liquidity management program is to maintain the Bank’s ability to meet the day-to-day cash flow requirements of our customers who either wish to withdraw funds or to draw upon credit facilities to meet their cash needs. Management believes that the Bank, on a stand-alone basis, has adequate liquid assets to meet its current obligations. The Bank’s primary funding source will continue to be deposits originating from its branch platform. The Bank’s wholesale funds historically consisted of FHLB advances and brokered deposits. As of December 31, 2014, the Bank had $99,000 of brokered deposits assumed from the acquisition of CBI.
	We monitor the sources and uses of funds on a regular basis to maintain an acceptable liquidity position. The Bank’s primary source of borrowings is the FHLB, from which the Bank is eligible to borrow up to 30 percent of its assets. As of December, 2014, the total borrowing capacity available based on pledged collateral and the remaining available borrowing capacity were $649.5 million and $499.5 million, respectively, compared to $343.3 million and $215.8 million, respectively, as of December 31, 2013. The Bank’s FHLB borrowings as of December 31, 2014 and December 31, 2013 totaled $150.0 million and $127.5 million, respectively, which represented 3.54 percent and 4.17 percent of assets as of December 31, 2014 and December 31, 2013, respectively.
	The amount that the FHLB is willing to advance differs based on the quality and character of qualifying collateral pledged by the Bank, and the advance rates for qualifying collateral may be adjusted upwards or downwards by the FHLB from time to time. To the extent deposit renewals and deposit growth are not sufficient to fund maturing and withdrawable deposits, repay maturing borrowings, fund existing and future loans and investment securities and otherwise fund working capital needs and capital expenditures, the Bank may utilize the remaining borrowing capacity from its FHLB borrowing arrangement.
	As a means of augmenting its liquidity, the Bank had an available borrowing source of $59.5 million from the Federal Reserve Discount Window, to which the Bank pledged loans with a carrying value of $82.3 million, and had no borrowings as of December 31, 2014. In December 2012, the Bank established a line of credit with Raymond James & Associates, Inc. for repurchase agreements up to $100.0 million. The Bank established unsecured federal funds lines of credit totaling $95.0 million from three financial institutions in June 2014 primarily to support short-term liquidity.
	The Bank has Contingency Funding Plans (“CFPs”) designed to ensure that liquidity sources are sufficient to meet its ongoing obligations and commitments, particularly in the event of a liquidity contraction. The CFPs are designed to examine and quantify its liquidity under various “stress” scenarios. Furthermore, the CFPs provide a framework for management and other critical personnel to follow in the event of a liquidity contraction or in anticipation of such an event. The CFPs address authority for activation and decision making, liquidity options and the responsibilities of key departments in the event of a liquidity contraction.

	Hanmi’s acquisition of Central Bancorp, Inc. (“CBI”), the parent company of United Central Bank, was completed on August 31, 2014. The combined companies began operating as Hanmi Financial Corporation and Hanmi Bank, respectively, with banking operations conducted under the Hanmi Bank brand effective as of September 1, 2014. The 2014 financial results reflect eight months of stand-alone operations of Hanmi and four months of combined operations. Hanmi’s accounting for this business combination is incomplete and has been recorded based on provisional amounts. The accounting is updated during the measurement period to reflect new information obtained about facts and circumstances that existed at the acquisition date. Adjustments to the provisional amounts during the measurement period are recognized as retrospective adjustments as of the date of the acquisition. During the fourth quarter Hanmi updated the valuation of assets and liabilities acquired in the transaction. As a result, the provisional values of certain assets and liabilities reported in the third quarter of 2014 have been updated to reflect the changes in estimated values. The results as of and for the quarter ended September 30, 2014, included herein, have been adjusted retrospectively to reflect measurement period adjustments to the provisional acquisition accounting values as of the acquisition date. The changes in provisional values resulted in a retrospective adjustment of $8.0 million to the bargain purchase gain that was provisionally reported for the third quarter of 2014 for a total bargain purchase gain of $14.6 million. This retrospective adjustment revises the reported third quarter net income to $21.8 million from $13.3 million as previously reported.

Summary of Operations	Summary of Operations
	Hanmi Financial Corporation (“Hanmi Financial,” the “Company,” “we,” “us” or “our”) was formed as a holding company of Hanmi Bank (the “Bank”) and registered with the Securities and Exchange Commission under the Act on March 17, 2001. Subsequent to its formation, each of the Bank’s shares was exchanged for one share of Hanmi Financial with an equal value. Our primary operations are related to traditional banking activities, including the acceptance of deposits and the lending and investing of money through operation of the Bank.
	On August 31, 2014, Hanmi Financial completed its acquisition of Central Bancorp, Inc., a Texas corporation (“CBI”) See “Note 2 — Acquisition.” During the second quarter of 2014, we sold two subsidiaries, Chun-Ha Insurance Services, Inc., a California corporation (“Chun-Ha”), and All World Insurance Services, Inc., a California corporation (“All World”). See “Note 4 — Sale of Insurance Subsidiaries and Discontinued Operations.”
	The Bank is a community bank conducting general business banking, with its primary market encompassing the Korean-American community as well as other ethnic communities across California, Texas, Illinois, Virginia, New Jersey, and New York. The Bank’s full-service offices are located in markets where many of the businesses are run by immigrants and other minority groups. The Bank’s client base reflects the multi-ethnic composition of these communities. The Bank is a California state-chartered financial institution insured by the FDIC. As of December 31, 2014, the Bank maintained a network of 49 full-service branch offices in California, Texas, Illinois, Virginia, New Jersey and New York, and loan production offices in California, Colorado, Texas, Virginia, and Washington State.
Basis of Presentation	Basis of Presentation
	The accounting and reporting policies of Hanmi Financial and subsidiaries conform, in all material respects, to U.S. generally accepted accounting principles (“GAAP”) and general practices within the banking industry. The information set forth in the following notes is presented on a continuing operations basis, unless otherwise noted. The following is a summary of the significant accounting policies consistently applied in the preparation of the accompanying Consolidated Financial Statements.
Principles of Consolidation	Principles of Consolidation
	The Consolidated Financial Statements include the accounts of Hanmi Financial and our wholly-owned subsidiary, the Bank. In addition, the accounts of Chun-Ha and All World are included for all periods presented through the date of sale, June 30, 2014. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant areas where estimates are made consist of the allowance for loan losses, other-than-temporary impairment, investment securities valuations, purchase credit impaired loans, the fair values of assets and liabilities acquired in a business combination and income taxes. Actual results could differ from those estimates.
Reclassifications	Reclassifications
	Certain reclassifications were made to the prior year’s presentation to conform to the current year’s presentation.
Cash and Cash Equivalents	Cash and Cash Equivalents
	Cash and cash equivalents include cash, due from banks, overnight federal funds sold and Treasury bills, all of which have original or purchased maturities of less than 90 days.
Investment Securities	Investment Securities
	Securities are classified into three categories and accounted for as follows:

		(i)	Securities that we have the positive intent and ability to hold to maturity are classified as “held to maturity” and reported at amortized cost;

		(ii)	Securities that are bought and held principally for the purpose of selling them in the near future are classified as “trading securities” and reported at fair value. Unrealized gains and losses are recognized in earnings; and

		(iii)	Securities not classified as held to maturity or trading securities are classified as “available for sale” and reported at fair value. Unrealized gains and losses are reported as a separate component of stockholders’ equity as accumulated other comprehensive income, net of income taxes.

	Accreted discounts and amortized premiums on investment securities are included in interest income using the effective interest method over the remaining period to the call date or contractual maturity and, in the case of mortgage-backed securities and securities with call features, adjusted for anticipated prepayments. Unrealized and realized gains or losses related to holding or selling of securities are calculated using the specific-identification method.
	We review investment securities on an ongoing basis for the presence of other-than-temporary impairment (“OTTI”) or permanent impairment, taking into consideration current market conditions, fair value in relationship to cost, extent and nature of the change in fair value, issuer rating changes and trends, whether we intend to sell a security or if it is likely that we will be required to sell the security before recovery of our amortized cost basis of the investment, which may be maturity, and other factors.
	For debt securities, the classification of OTTI depends on whether we intend to sell the security or if it is more likely than not that we will be required to sell the security before recovery of its cost basis, and on the nature of the impairment. If we intend to sell a security or if it is more likely than not that we will be required to sell the security before recovery, an OTTI write-down is recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value. If we do not intend to sell the security or it is not more likely than not that we will be required to sell the security before recovery, the OTTI write-down is separated into an amount representing credit loss, which is recognized in earnings, and the amount related to all other factors, which is recognized in other comprehensive income net of tax. A credit loss is the difference between the cost basis of the security and the present value of cash flows expected to be collected, discounted at the security’s effective interest rate at the date of acquisition. The cost basis of an other than temporarily impaired security is written down by the amount of impairment recognized in earnings. The new cost basis is not adjusted for subsequent recoveries in fair value.
Loans Receivable	Loans Receivable
	Originated loans: Loans are originated by the Company with the intent to hold them for investment and are stated at the principal amount outstanding, net of unearned income. Unearned income includes deferred unamortized nonrefundable loan fees and direct loan origination costs. Net deferred fees or costs are recognized as an adjustment to interest income over the contractual life of the loans using the effective interest method or taken into income when the related loans are paid off or sold. The amortization of loan fees or costs is discontinued when a loan is placed on nonaccrual status. Interest income is recorded on an accrual basis in accordance with the terms of the respective loan and includes prepayment penalties.
	Purchased loans: Purchased loans are stated at the principal amount outstanding, net of unearned discounts or unamortized premiums. All loans acquired in our acquisitions are initially measured and recorded at their fair value on the acquisition date. A component of the initial fair value measurement is an estimate of the credit losses over the life of the purchased loans. Purchased loans are also evaluated for impairment as of the acquisition date and are accounted for as “acquired non-impaired” or “purchased credit impaired” loans.
	Acquired non-impaired loans: Acquired non-impaired loans are those loans for which there was no evidence of credit deterioration at their acquisition date and it was probable that we would be able to collect all contractually required payments. Acquired non-impaired loans, together with originated loans, are referred to as non-purchased credit impaired (“Non-PCI”) loans. Purchase discount or premium on acquired non-impaired loans is recognized as an adjustment to interest income over the contractual life of such loans using the effective interest method or taken into income when the related loans are paid off or sold.
	Purchased credit impaired loans. Purchased credit impaired (“PCI”) loans are accounted for in accordance with ASC Subtopic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” A purchased loan is deemed to be credit impaired when there is evidence of credit deterioration since its origination and it is probable at the acquisition date that we would be unable to collect all contractually required payments. We apply PCI loan accounting when (i) we acquire loans deemed to be impaired, and (ii) as a general policy election for non-impaired loans that we acquire in a distressed bank acquisition.
	For PCI loans, at the time of acquisition we (i) calculated the contractual amount and timing of undiscounted principal and interest payments (the “undiscounted contractual cash flows”) and (ii) estimated the amount and timing of undiscounted expected principal and interest payments (the “undiscounted expected cash flows”). The difference between the undiscounted contractual cash flows and the undiscounted expected cash flows is the nonaccretable difference. The nonaccretable difference represents an estimate of the loss exposure of principal and interest related to the PCI loan portfolios; such amount is subject to change over time based on the performance of such loans. The carrying value of PCI loans is reduced by payments received, both principal and interest, and increased by the portion of the accretable yield recognized as interest income.

	The excess of expected cash flows at acquisition over the initial fair value of acquired impaired loans is referred to as the “accretable yield” and is recorded as interest income over the estimated life of the loans using the effective yield. If estimated cash flows are indeterminable, the recognition of interest income will cease to be recognized.
	At acquisition, the Company may aggregate PCI loans into pools having common credit risk characteristics such as product type, geographic location and risk rating. Increases in expected cash flows over those previously estimated increase the accretable yield and are recognized as interest income prospectively. Decreases in the amount and changes in the timing of expected cash flows compared to those previously estimated decrease the accretable yield and usually result in a provision for loan losses and the establishment of an allowance for loan losses. As the accretable yield increases or decreases from changes in cash flow expectations, the offset is a decrease or increase to the nonaccretable difference. The accretable yield is measured at each financial reporting date based on information then currently available and represents the difference between the remaining undiscounted expected cash flows and the current carrying value of the loans.
	PCI loans that are contractually past due are still considered to be accruing and performing as long as there is an expectation that the estimated cash flows will be received. If the timing and amount of cash flows is not reasonably estimable, the loans may be classified as nonaccrual with interest income recognized on either a cash basis or as a reduction of the principal amount outstanding.
	Non-PCI loans are placed on nonaccrual status when, in the opinion of management, the full timely collection of principal or interest is in doubt. Generally, the accrual of interest is discontinued when principal or interest payments become more than 90 days past due. However, in certain instances, we may place a particular loan on nonaccrual status earlier, depending upon the individual circumstances surrounding the loan’s delinquency. When an asset is placed on nonaccrual status, previously accrued but unpaid interest is reversed against current income. Subsequent collections of cash are applied as principal reductions when received, except when the ultimate collectability of principal is probable, in which case interest payments are credited to income. Nonaccrual assets may be restored to accrual status when principal and interest become current and full repayment is expected. Interest income is recognized on the accrual basis for impaired loans not meeting the criteria for nonaccrual.
	Nonperforming assets consist of loans on nonaccrual status, loans 90 days or more past due and still accruing interest, loans restructured with troubled borrowers where the terms of repayment have been renegotiated resulting in a reduction or deferral of interest or principal, and other real estate owned (“OREO”). Loans are generally placed on nonaccrual status when they become 90 days past due unless management believes the loan is adequately collateralized and in the process of collection. Additionally, the Bank may place loans that are not 90 days past due on nonaccrual status, if management reasonably believes the borrower will not be able to comply with the contractual loan repayment terms and collection of principal or interest is in question.
Loans Held for Sale	Loans Held for Sale
	Loans originated, or transferred from loans receivable, and intended for sale in the secondary market are carried at the lower of aggregate cost or fair market value. Fair market value, if lower than cost, is determined based on valuations obtained from market participants or the value of underlying collateral, calculated individually. A valuation allowance is established if the market value of such loans is lower than their cost and net unrealized losses, if any, are recognized through a valuation allowance by charges to income. 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.
Impaired Loans	Impaired Loans
	Loans are identified and classified as impaired when it is probable that not all amounts, including principal and interest, will be collected in accordance with the contractual terms of the loan agreement. The Bank will consider the following loans as impaired: nonaccrual loans or loans where principal or interest payments have been contractually past due for 90 days or more, unless the loan is both well-collateralized and in the process of collection; loans classified as troubled debt restructuring loans.
	The Bank considers whether the borrower is experiencing problems such as operating losses, marginal working capital, inadequate cash flow or business deterioration in realizable value. The Bank also considers the financial condition of a borrower who is in industries or countries experiencing economic or political instability.
	When a loan is considered impaired, any future cash receipts on such loans will be treated as either interest income or return of principal depending upon management’s opinion of the ultimate risk of loss on the individual loan. Cash payments are treated as interest income where management believes the remaining principal balance is fully collectible.
	We evaluate loan impairment in accordance with applicable GAAP. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as a practical 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, the deficiency will be charged off against the allowance for loan losses or, alternatively, a specific allocation will be established. Additionally, impaired loans are specifically excluded from the quarterly migration analysis when determining the amount of the allowance for loan losses required for the period.
	For impaired loans where the impairment amount is measured based on the present value of expected future cash flows discounted at the loan’s original effective interest rate, any impairment that represents the change in present value attributable to the passage of time is recognized as provision for credit losses.
Troubled Debt Restructuring	Troubled Debt Restructuring
	A loan is identified as a troubled debt restructuring (“TDR”) when a borrower is experiencing financial difficulties and, for economic or legal reasons related to these difficulties, the Bank grants a concession to the borrower in the restructuring that it would not otherwise consider. The Bank has granted a concession when, as a result of the restructuring, 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. TDRs are reviewed for potential impairment. 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. 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.
Premises and Equipment	Premises and Equipment
	Premises and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are computed 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 improvements		10 to 30 years
	Furniture and equipment		3 to 10 years
	Leasehold improvements		Term of lease or useful life, whichever is shorter
	Software		3 years
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets
	We account for long-lived assets in accordance with the provisions of FASB ASC 360, “Property, Plant and Equipment.” This requires that long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net undiscounted cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.
Other Real Estate Owned	Other Real Estate Owned
	Assets acquired through loan foreclosure are recorded at the lower of cost or fair value less estimated costs to sell when acquired. If fair value declines subsequent to foreclosure, valuation impairment is recorded through expense. Operating costs after acquisition are expensed.
Servicing Assets and Servicing liabilities	Servicing Assets and Servicing liabilities
	Servicing assets and servicing liabilities are initially recorded at fair value in accordance with the provisions of FASB ASC 860, “Transfers and Servicing.” The fair values of servicing assets and servicing liabilities represent either the price paid if purchased, or the allocated carrying amounts based on relative values when retained in a sale. Servicing assets and servicing liabilities are amortized in proportion to, and over the period of, estimated net servicing income. The fair value of servicing assets and servicing liabilities are determined based on the present value of estimated net future cash flows related to contractually specified servicing fees and costs.
	The servicing assets and servicing liabilities are recorded based on the present value of the contractually specified servicing fee, net of adequate compensation, for the estimated life of the loan, using a discount rate and a constant prepayment rate. Management periodically evaluates the servicing assets and servicing liabilities for impairment. Impairment, if it occurs, is recognized in a valuation allowance in the period of impairment.
	Interest-only strips are recorded based on the present value of the excess of total servicing fee over the contractually specified servicing fee for the estimated life of the loan, calculated using the same assumptions as noted above. Such interest-only strips are accounted for at their estimated fair value, with unrealized gains or losses recorded as adjustments to accumulated other comprehensive income (loss).
Other Intangible Assets	Other Intangible Assets
	Other intangible assets consist of acquired intangible assets arising from acquisitions, including core deposit intangibles, trade names, client/insured relationships and carrier relationships. The acquired intangible assets were initially measured at fair value and then are amortized on the straight-line method over their estimated useful lives.
	As required by FASB ASC 350, other intangible assets are assessed for impairment or recoverability whenever events or changes in circumstances indicate the carrying amount may not be recoverable.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock
	The Bank is a member of the Federal Home Loan Bank (“FHLB”) of San Francisco and is required to own common stock in the FHLB based upon the Bank’s balance of outstanding FHLB advances. FHLB stock is carried at cost and may be sold back to the FHLB at its carrying value. FHLB stock is periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends received are reported as dividend income.
Federal Reserve Bank Stock	Federal Reserve Bank Stock
	The Bank is a member of the Federal Reserve Bank (“FRB”) of San Francisco and is required to maintain stock in the FRB based on a specified ratio relative to the Bank’s capital. FRB stock is carried at cost and may be sold back to the FRB at its carrying value. FRB stock is periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends received are reported as dividend income.
Bank-Owned Life Insurance	Bank-Owned Life Insurance
	We have purchased single premium life insurance policies (“bank-owned life insurance”) on certain officers. The Bank is the beneficiary under the policy. In the event of the death of a covered officer, we will receive the specified insurance benefit from the insurance carrier. Bank-owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due, if any, that are probable at settlement.
Affordable Housing Investments	Affordable Housing Investments
	The Bank has invested in limited partnerships formed to develop and operate affordable housing units for lower income tenants throughout California. The partnership interests are accounted for utilizing the proportional amortization method with amortization expense and tax benefits recognized through the income tax provision in accordance with ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects.
Income Tax	Income Tax
	We provide for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized.
Share-Based Compensation	Share-Based Compensation
	We adopted FASB ASC 718, “Compensation-Stock Compensation,” on January 1, 2006 using the “modified prospective” method. Under this method, awards that are granted, modified or settled after December 31, 2005 are measured and accounted for in accordance with FASB ASC 718. Also under this method, expense is recognized for services attributed to the current period for unvested awards that were granted prior to January 1, 2006, based upon the fair value determined at the grant date under SFAS No. 123, “Accounting for Stock-Based Compensation.”
	FASB ASC 718 requires that cash flows resulting from the realization of excess tax benefits recognized on awards that were fully vested at the time of adoption of FASB ASC 718 be classified as a financing cash inflow and an operating cash outflow on the Consolidated Statements of Cash Flows. Before the adoption of FASB ASC 718, we presented all tax benefits realized from the exercise of stock options as an operating cash inflow.
	In addition, FASB ASC 718 requires that any unearned compensation related to awards granted prior to the adoption of FASB ASC 718 be eliminated against the appropriate equity accounts. As a result, the presentation of stockholders’ equity was revised to reflect the transfer of the balance previously reported in unearned compensation to additional paid-in capital.
Earnings per Share	Earnings per Share
	Basic earnings per share is computed by dividing earnings available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution of securities that could share in the earnings.
Treasury Stock	Treasury Stock
	We use the cost method of accounting for treasury stock. The cost method requires us to record the reacquisition cost of treasury stock as a deduction from stockholders’ equity on the Consolidated Balance Sheets.
Business Combinations	Business Combinations
	Business combinations completed after January 1, 2009, are accounted for under the acquisition method of accounting in accordance with ASC Topic 805, “Business Combinations.” Under the acquisition method, the acquiring entity in a business combination recognizes 100 percent of the acquired assets and assumed liabilities, regardless of the percentage owned, at their estimated fair values as of the date of acquisition. Any excess of the purchase price over the fair value of net assets and other identifiable intangible assets acquired is recorded as goodwill. To the extent the fair value of net assets acquired, including other identifiable assets, exceeds the purchase price, a bargain purchase gain is recognized. Assets acquired and liabilities assumed from contingencies must also be recognized at fair value, if the fair value can be determined during the measurement period. Results of operations of an acquired business are included in the statement of earnings from the date of acquisition. Acquisition-related costs, including conversion and restructuring charges, are expensed as incurred.
Recently Issued Accounting Standards	Recently Issued Accounting Standards
	FASB ASU 2014-17, *Pushdown Accounting (a consensus of the FASB Emerging Issues Task Force)*, which allows an acquired entity to elect to apply pushdown accounting in its separate financial statements on a change-in-control event. The acquired entity elects whether to apply pushdown accounting individually for each change-in-control event, and may apply pushdown accounting during the reporting period in which the change-in-control event occurs. Effective November 18, 2014, an acquired entity may apply ASU 2014-17 to future change-in-control events. The Company did not make an election to apply FASB ASU 2014-17 for the acquisition of CBI, which has no impact on our financial condition or result of operations.

	FASB ASU 2014-08, *Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity*, was issued to change the criteria for reporting discontinued operations and requires additional disclosures about discontinued operations. ASU 2014-08 requires that an entity report as a discontinued operation only a disposal that represents a strategic shift in operations that has a major effect on its operations and financial results. ASU 2014-08 is effective prospectively for new disposals (or classifications as held-for-sale) that occur within annual periods beginning on or after December 15, 2014, and interim periods within those annual periods, for public business entities and not-for-profit entities that have issued (or are a conduit obligor for) securities that are traded, listed, or quoted on an exchange or an over-the-counter market. For other entities, the ASU is effective for disposals (or classifications as held-for-sale) that occur within annual periods beginning on or after December 15, 2014, and interim periods thereafter. The adoption of the ASU is not expected to have a significant impact on our financial condition or result of operations.
	FASB ASU 2014-04, **Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (Topic 310-40**), was issued to define the term in substance a repossession or foreclosure and physical possession in accounting literature and when a creditor should derecognize the loan receivable and recognize the real estate property. The amendments in this update are intended to reduce diversity in practice by clarifying when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. The amendment is effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The adoption of FASB ASU 2014-04 is not expected to have a significant impact on our financial condition or result of operations.
	FASB ASU 2014-01, *Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the Emerging Issues Task Force)*, was issued to permit a reporting entity to make an accounting policy election to account for investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. The amendments are expected to enable more entities to record the amortization of the investment in income tax expense together with the tax credits and other tax benefits generated from the partnership. The ASU is effective retrospectively for public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. For all entities other than public business entities, the amendments are effective retrospectively for annual periods beginning after December 15, 2014, and interim periods within annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company adopted the ASU effective April 1, 2014. See “Note 3— Accounting for Investment in Qualified Affordable Housing Projects.” for further details.
Fair Value Measurements	The estimated fair value of financial instruments has been determined by using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret market data in order to develop estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that we could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.
Non-PCI Loans [Member]
Allowance for Loan Losses	Allowance for Loan Losses on Non-PCI Loans
	Management believes the allowance for loan losses is adequate to provide for probable losses inherent in the loan portfolio. However, the allowance is an estimate that is inherently uncertain and depends on the outcome of future events. Management’s estimates are based on previous loan loss experience; volume, growth and composition of the loan portfolio; the value of collateral; and current economic conditions. Our lending is concentrated generally in commercial, consumer, construction and real estate loans primarily in California, Illinois, and Texas.
	Provisions to allowance for loan losses are made quarterly to recognize probable loan losses. The quarterly provision is based on the allowance need, which is determined through analysis involving quantitative calculations based on historic loss rates for general reserves and individual impairment calculations for specific allocations to impaired loans as well as qualitative adjustments.
	In the first quarter of 2010, the look-back period was reduced from twelve quarters to eight quarters, with 60 percent weighting given to the most recent four quarters and 40 percent to the oldest four quarters, to place greater emphasis on losses taken by the Bank during the economic downturn. In the second quarter of 2013, management reevaluated the look-back period and restored the twelve quarter look-back period, with 50 percent weighting given to the most recent four quarters, 33 percent to the next four quarters and 17 percent to the oldest four quarters, in order to capture a period of higher losses that would have otherwise been excluded. In the first quarter of 2014, management again evaluated the look-back period and extended the periods to sixteen quarters to continue capturing a period of higher losses that would have been dropped off and to reflect potential losses in our current credit portfolio. Risk factor calculations are weighted at 46.0 percent for the first four quarters, 31.0 percent for the second four quarters, 15.0 percent for the third four quarters, and 8.0 percent for the last four quarters. The change in methodology maintained the Bank’s allowance at a level consistent with the prior quarter.
	To determine general reserve requirements, existing loans are divided into 11 general loan pools of risk-rated loans as well as three homogenous loan pools. For risk-rated loans, migration analysis allocates historical losses by loan pool and risk grade to determine risk factors for potential loss inherent in the current outstanding loan portfolio. As 3 homogeneous loans are bulk graded, the risk grade is not factored into the historical loss analysis. In addition, specific reserves are allocated for loans deemed “impaired.”
	When determining the appropriate level for allowance for loan losses, management considers qualitative adjustments for any factors that are likely to cause estimated credit losses associated with the Bank’s current portfolio to differ from historical loss experience, including, but not limited to, national and local economic and business conditions, volume and geographic concentrations, and problem loan trends.
	To systematically quantify the credit risk impact of trends and changes within the loan portfolio, a credit risk matrix is utilized. The qualitative factors are considered on a loan pool by loan pool basis subsequent to, and in conjunction with, a loss migration analysis. The credit risk matrix provides various scenarios with positive or negative impact on the portfolio along with corresponding basis points for qualitative adjustments.
	Loan losses are charged off, and recoveries are credited, to the allowance account. Additions to the allowance account are charged to the provision for credit losses. The allowance for loan losses is maintained at a level considered adequate by management to absorb probable losses in the loan portfolio. The adequacy of the allowance is determined by management based upon an evaluation and review of the loan portfolio, consideration of historical loan loss experience, current economic conditions, changes in the composition of the loan portfolio, analysis of collateral values and other pertinent factors.
	Loans are measured for impairment when it is probable that not all amounts, including principal and interest, will be collected in accordance with the original contractual terms of the loan agreement. The amount of impairment and any subsequent changes are recorded through the provision for credit losses as an adjustment to the allowance for loan losses.
	The Bank follows the “Interagency Policy Statement on the Allowance for Loan and Lease Losses” and, as an integral part of the quarterly credit review process, the allowance for loan losses and allowance for off-balance sheet items are reviewed for adequacy. The California Department of Business Oversight and/or the Board of Governors of the Federal Reserve System (“Federal Reserve”) require the Bank to recognize additions to the allowance for loan losses based upon their assessment of the information available to them at the time of their examinations.
	In general, the Bank will charge off a loan and declare a loss when its collectability is questionable and when the Bank can no longer justify presenting the loan as an asset on its balance sheet. To determine if a loan should be charged off, all possible sources of repayment are analyzed, including the potential for future cash flow from income or liquidation of other assets, the value of any collateral, and the strength of co-makers or guarantors. When these sources do not provide a reasonable probability that principal can be collected in full, the Bank will fully or partially charge off the loan.
	For a real estate loan, including commercial term loans secured by collateral, any impaired portion is considered as loss if the loan is more than 90 days past due. In a case where the fair value of collateral is less than the loan balance and the borrower has no other assets or income to support repayment, the amount of the deficiency is considered a loss and charged off.
	For a commercial and industrial loan other than those secured by real estate, if the borrower is in the process of a bankruptcy filing in which the Bank is an unsecured creditor or deemed virtually unsecured by lack of collateral equity or lien position and the borrower has no realizable equity in assets and prospects for recovery are negligible, the loan is considered a loss and charged off. Additionally, a commercial and industrial unsecured loan that is more than 120 days past due is considered a loss and charged off.
	For an unsecured consumer loan where a borrower files for bankruptcy, the loan is considered a loss within 60 days of receipt of notification of filing from the bankruptcy court. Other consumer loans are considered a loss if they are more than 90 days past due. Other events, such as bankruptcy, fraud, or death result in charge offs being recorded in an earlier period.
PCI Loans [Member]
Allowance for Loan Losses	Allowance for Loan Losses on PCI Loans
	The PCI loans are subject to our internal and external credit review. If deterioration in the expected cash flows results in a reserve requirement, a provision for credit losses is charged to earnings. For PCI loans, the allowance for loan losses is measured at the end of each financial reporting period based on expected cash flows. Decreases or increases in the amount and changes in the timing of expected cash flows on the PCI loans as of the financial reporting date compared to those previously estimated are usually recognized by recording a provision or a negative provision for credit losses on such loans.

	(1)	Reflects a zero coupon tax credit municipal bond. As the Company was not able to obtain a price from independent external pricing service providers, the discounted cash flow method was used to determine its fair value. The bond carried a par value of $700,000 and an amortized value of $700,000 with a remaining life of 0.23 years at December 31, 2014.
	(2)	Reflects two equity securities that are not actively traded. The fair value of one equity security with a fair value of $214,000 was computed using valuation multiples (price to book and price to earnings) derived from market transactions for comparable companies. The other equity security with a fair value of $200,000 was computed using valuation multiples (price to book and price to earnings) derived from 1) market transactions for comparable companies, and 2) publicly-traded comparable companies.
	(3)	Reflects warrants for our common stock issued in connection with services Cappello Capital Corp. provided to us as a placement agent in connection with our best efforts public offering and as our financial adviser in connection with our completed rights offering. The warrants were immediately exercisable when issued at an exercise price of $9.60 per share of our common stock and expire on October 14, 2015. As of December 31, 2014, there were no outstanding stock warrants. See “Note 13 – Stockholders’ Equity” for more details.

Business combination, date of completion			Under the acquisition method of accounting in accordance with ASC Topic 805, bBusiness Combinations.b Under the acquisition method, the acquiring entity in a business combination recognizes 100 percent of the acquired assets and assumed liabilities, regardless of the percentage owned, at their estimated fair values as of the date of acquisition. Any excess of the purchase price over the fair value of net assets and other identifiable intangible assets acquired is recorded as goodwill. To the extent the fair value of net assets acquired, including other identifiable assets, exceeds the purchase price, a bargain purchase gain is recognized. Assets acquired and liabilities assumed from contingencies must also be recognized at fair value, if the fair value can be determined during the measurement period. Results of operations of an acquired business are included in the statement of earnings from the date of acquisition. Acquisition-related costs, including conversion and restructuring charges, are expensed as incurred.
