	Note 1 — Basis of Presentation
	Hanmi Financial Corporation (“Hanmi Financial,” the “Company,” “we” or “us”) is a Delaware corporation and is subject to the Bank Holding Company Act of 1956, as amended. Hanmi Bank (the “Bank”), a California state chartered bank, is a wholly owned subsidiary of Hanmi Financial. During the second quarter of 2014, we disposed of 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.” On August 31, 2014, Hanmi Financial completed its acquisition of Central Bancorp, Inc. See “Note 2 — Acquisition.”
	In management’s opinion, the accompanying unaudited consolidated financial statements of Hanmi Financial and its subsidiaries reflect all adjustments of a normal and recurring nature that are necessary for a fair presentation of the results for the interim period ended September 30, 2014, but are not necessarily indicative of the results that will be reported for the entire year or any other interim period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. The aforementioned unaudited consolidated financial statements are in conformity with GAAP. Such interim consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission. The interim information should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 2013 (the “2013 Annual Report on Form 10-K”).
	The preparation of interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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. Actual results could differ from those estimates. Material estimates subject to change include, among other items, the fair value estimates of assets acquired and liabilities assumed in Central Bancorp, Inc. (“CBI”) acquisition as discussed in “Note 2 – Acquisition.” The acquired assets and assumed liabilities of Central Bancorp, Inc. were measured at their estimated fair values. The Company made significant estimates and exercised significant judgment in estimating fair values and accounting for such acquired assets and assumed liabilities.
	Descriptions of our significant accounting policies are included in “Note 1 — Summary of Significant Accounting Policies” in our 2013 Annual Report on Form 10-K. During the three months ended June 30, 2014, we adopted an accounting policy related to accounting for investments in low-income housing tax credit according to Financial Accounting Standards Board (“FASB”) ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. See “Note 3 — Accounting for Investments in Qualified Affordable Housing Projects.” During the three months ended September 30, 2014, we completed acquisition of CBI and our acquisition was accounted for using the acquisition method of accounting. See “Note 2 —Acquisition” for more information about the CBI acquisition and “Note 6 — Loans” for accounting policies regarding purchased loans.

	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 and cumulative unpaid dividends and $1.6 million for accrued interest payable on CBI subordinated debentures 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 $1.26 billion, $1.17 billion and $86.8 million, respectively. Total loans and deposits were $294.0 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.
	In connection with the acquisition, the consideration paid, the provisional estimate of the fair value of the assets acquired and the liabilities assumed as of August 31, 2014 are summarized in the following table:
		(In thousands)
	Consideration paid:
	CBI Stockholders	$	50,000
	Redemption of preferred stock and cumulative unpaid dividends		28,675

	Total liabilities assumed		1,169,095
	Total identifiable net assets	$	86,834
	Bargain purchase gain, net of deferred taxes	$	6,593
	The CBI 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. The provisional application of the acquisition method of accounting resulted in a bargain purchase gain of $6.6 million. The operations of CBI are included in our operating results since the acquisition date for the third quarter of 2014. Acquisition-related costs of $3.6 million for the nine months ended September 30, 2014 are expensed as incurred as merger and integration costs. These expenses are comprised primarily of system conversion costs and professional fees.
	The $294.0 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 purchased credit impaired loans acquired from the CBI merger at August 31, 2014.
		(In thousands)
	Undiscounted contractual cash flows	$	117,301
	Nonaccretable discount		(18,565	)
	Undiscounted cash flow to be collected		98,736
	Estimated fair value of PCI loans		75,878
	Accretable yield	$	22,858
	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 third quarter of 2014 was $33,000.
	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 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 $591,000 amortized in the third quarter of 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 third quarter of 2014 was $35,000.
	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. The unaudited pro forma information is intended for informational purposes only and is not necessarily indicative of our future operating results or operating results that would have occurred had the CBI acquisition been completed at the beginning of 2013. No assumptions have been applied to the pro forma results of operations regarding possible revenue enhancements, expense efficiencies or asset dispositions.

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 income in the three and nine months ended September 30, 2013 increased by $135,000 and $51,000, 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 September 30, 2014 or December 31, 2013. The investment in low income housing was $21.8 million and $3.0 million as of September 30, 2014 and December 31, 2013, respectively. The Bank’s unfunded commitments related to low income housing investments was $12.6 million as of September 30, 2014 and there were none as of December 31, 2013. The Bank recognized $592,000 and $1.0 million as a component of income tax expense during the three and nine months ended September 30, 2014, respectively, and tax credits and other benefits received from the tax expenses were $821,000 and $1.4 million during the three and nine months ended September 30, 2014, respectively.

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. 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 and a $4,000 income tax benefit from operating loss, offset by a $470,000 capital gain tax and a $52,000 operating loss. Consequently, net loss from discontinued operations in the second quarter of 2014 was $467,000, or $0.01 per diluted share. The discontinued operations generated noninterest income, primarily in the line item for insurance commissions, of $2.7 million in the first six months of 2014 and $1.3 million in the first quarter of 2014. They also incurred noninterest expense of $2.7 million in various line items in the first six months of 2014 and $1.4 million in the first quarter of 2014.

All individual securities that have been in a continuous unrealized loss position for 12 months or longer as of September 30, 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 September 30, 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 September 30, 2014 and December 31, 2013 were not other-than-temporarily impaired, and therefore, no impairment charges as of September 30, 2014 and December 31, 2013 were warranted.

	Note 6 — Loans
	The loan portfolio includes originated and purchased loans. Originated loans and purchased 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, are referred to collectively as non-purchased credit impaired loans, or “Non-PCI loans.” Purchased loans for which there was, at the acquisition date, evidence of credit deterioration since their origination and it was probable that we would be unable to collect all contractually required payments are referred to as purchased credit impaired loans, or “PCI loans”.
	Non-PCI loans are carried at the principal amount outstanding, net of deferred fees and costs, and in the case of acquired loans, net of purchase discounts and premiums. Deferred fees and costs and purchase discounts and premiums on acquired non-impaired loans 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.
	PCI loans are accounted for in accordance with ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” For PCI loans, at the time of acquisition, we (i) calculate the contractual amount and timing of undiscounted principal and interest payments (the “undiscounted contractual cash flows”) and (ii) estimate 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 difference between the undiscounted cash flows expected to be collected and the estimated fair value of the acquired loans is the accretable yield. The accretable yield is recorded as interest income over the estimated life of the loans using the effective yield method if the timing and amount of the future cash flows is reasonably estimable. PCI loans may be placed on nonaccrual status, including use of the cost recovery method or cash basis method of income recognition, if information is not available to reasonably estimate cash flows expected to be collected to compute its yield. The nonaccretable difference represents an estimate of the loss exposure of principal and interest related to PCI loans; 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.
	As part of the fair value process and the subsequent accounting, the Company aggregates PCI loans into pools having common credit risk characteristics such as type 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.
	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 functions that review and monitor pass graded loans as well as problem loans to prevent further deterioration.
	The majority of the Bank’s loan portfolio consists of commercial real estate and commercial and industrial loans. The Bank has been diversifying and monitoring commercial real estate loans based on property types, underwriting standards, and portfolio liquidity and management, and certain specified limits set forth in the Bank’s loan policy. To date, most of the Bank’s lending activity occurred within Southern California. With the acquisition of CBI, our lending activities in other areas of the country will increase.

There was no allowance for loan losses on our PCI loans as of September 30, 2014. The allowance for off-balance sheet items is maintained at a level believed to be sufficient to absorb estimated 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 September 30, 2014 and 2013, the allowance for off-balance sheet items amounted to $1.5 million and $1.3 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 in all respects 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 incorporates all performing loans with no 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.
As of September 30, 2014 and December 31, 2013, pass/pass-watch (grade 0-4), criticized (grade 5) and classified (grade 6-7) loans (excluding PCI loans), disaggregated by loan class, were as follows:

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 Troubled Debt Restructuring (“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.

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.

Loans on nonaccrual status, excluding loans held for sale, totaled $24.0 million as of September 30, 2014, compared to $25.9 million as of December 31, 2013, representing a 7.2 percent decrease. Delinquent loans (defined as 30 days or more past due), excluding loans held for sale, were $19.2 million as of September 30, 2014, compared to $16.3 million as of December 31, 2013, representing a 18.2 percent increase.
As of September 30, 2014, other real estate owned (“OREO”) consisted of forty properties, of which $20.2 million and $4.6 million were commercial and residential properties, respectively, with a combined carrying value of $24.8 million and no valuation adjustment. Of $24.8 million, $22.3 million was OREOs assumed in the CBI acquisition. 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.

As of September 30, 2014 and December 31, 2013, total TDRs, excluding loans held for sale, were $26.4 million and $30.0 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 September 30, 2014 and December 31, 2013, TDRs, excluding loans held for sale, were subjected to specific impairment analysis, and $3.7 million and $2.8 million, respectively, of reserves relating to these loans were included in the allowance for loan losses.

At September 30, 2014 and 2013, we serviced loans sold to unaffiliated parties in the amounts of $341.6 million and $330.4 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
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 CBI acquisition. There is a three-year recovery period which begins at the expiration of the Commercial SLA. During this period, 80% of any recoveries of previously charged-off and reimbursed Commercial SLA loans need to be reimbursed to the FDIC. As of September 30, 2014, the FDIC loss sharing asset was related to $7.7 million net receivable from the FDIC. Single-family loans under the Single family SLA as of September 30, 2014 were $3.7 million.

	Note 7 — Income Taxes
	The Company’s income tax expenses for the continuing operations were $5.0 million for the three months ended September 30, 2014, compared to $6.6 million for the same period in 2013. The effective income tax rate was 27.25 percent for the three months ended September 30, 2014, compared to 38.95 percent for the same period in 2013. For the nine months ended September 30, 2014, income tax expense for the continuing operations were $19.7 million, compared to $17.5 million for the same period in 2013. The effective income tax rate was 35.48 percent, compared to 41.42 percent for the same period in 2013. The decrease in the effective tax rate for the three months ended September 30, 2014 was due mainly to tax rate reduction to the adjustment for the nontaxable bargain purchase gain, which is excluded from taxable income. The decrease in the effective tax rate for the nine months ended September 30, 2014, as compared to the same period in 2013, was due mainly to tax rate reduction to the adjustment for the bargain purchase gain, a $400,000 deferred tax benefit generated from the sale of the insurance businesses and tax benefits to be realized from investments in low income tax credit funds, offset by the expiration of the California EZ net interest deduction and EZ hiring credits. Management concluded that no valuation allowance is required for the deferred tax assets except for the portion related to certain state net operating losses as of September 30, 2014.
	As of September 30, 2014, the Company was subject to examinations by various federal and state tax authorities for the tax years ended December 31, 2004 through 2013. As of September 30, 2014, the Company was subjected to audits or examinations by the Internal Revenue Service for the 2009 tax year and the California Franchise Tax Board for the 2008 and 2009 tax years. Management does not anticipate any material changes in our financial statements due to the results of the audits.

	Subordinated Debentures
	During the third quarter of 2014 with the acquisition of CBI, the Company assumed CBI’s Junior Subordinated Deferrable Interest Debentures (“Subordinated Debentures”) with a notional 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 Subordinated Debentures. The Subordinated Debentures will mature on December 31, 2035, which date may be shortened to, at the Bank’s option if certain conditions are met. The TPS will be subject to mandatory redemption if the Subordinated Debentures are repaid by the Bank. Interest is payable quarterly, and the Bank has the option to defer interest payments on the Subordinated Debentures from time to time for a period not to exceed five consecutive years. Interest expense related to the amortization discount was 35,000 for the three months ended September 30, 2014.
	Rescinded Stock Obligation
	Hanmi Finanical assumed a rescinded stock obligation of $15.7 million and related accrued interest payable of $4.9 million at the closing date. The obligation resulted from the issuance of CBI common shares more than what was legally authorized in 2009 and 2010. Interest has been accrued on the obligation with interest rates varying state to state. Interest expense of $87,000 was recorded in September 2014, reflecting a weighted average rate of 6.79%. Accrued interest on the obligation as of September 30, 2014 was $5.1 million. Hanmi Financial has been in the process of paying off the obligation since the acquisition date.

	Stock Warrants
	As part of the 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 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 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 third quarter of 2014, the remaining stock warrants were exercised and there were no outstanding stock warrants as of September 30, 2014.

	Risk-Based Capital
	Federal bank regulatory agencies require bank holding companies and banks to maintain a minimum ratio of qualifying total capital to risk-weighted assets of 8.0 percent and a minimum ratio of Tier 1 capital to risk-weighted assets of 4.0 percent. In addition to the risk-based guidelines, the 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,” the 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, the 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, an institution is 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 will become 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

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Note 12 — 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 September 30, 2014, we had a zero coupon tax credit municipal bond of $718,000 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 September 30, 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 0.48 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 September 30, 2014 and December 31, 2013, we had $7.8 million and zero of 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 September 30, 2014 and December 31, 2013, 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 September 30, 2014 and December 31, 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 three months ended September 30, 2014. As of September 30, 2014 and December 31, 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 0.48 year at September 30, 2014.
(2)	Reflects two equity securities that are not actively traded. The fair value of one equity security with a fair value of $250,000 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. In addition to these approaches, the Company considered a discounted cash flow approach, which cash flows, calculated based on a redemption or liquidation policy of the equity issuer, are discounted back to the present using a 10.5% discount rate.
(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. There were no outstanding stock warrants as of September 30, 2014. See “Note 9 – 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 at fair value 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 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 is 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 – Servicing asset is carried at its implied fair value. The fair value of the servicing asset is 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).

Earnings Per Share [Abstract]	'
Earnings Per Share	'
	Note 14 — 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 stock options or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that would then share 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:

	Note 15 — 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:

	Hanmi Financial
	Management believes that Hanmi Financial, on a stand-alone basis, has adequate liquid assets to meet its operating cash needs through September 30, 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 September 30, 2014, the Bank had $99,000 brokered deposits assumed from the CBI acquisition.
	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 September 30, 2014, the total borrowing capacity available based on pledged collateral and the remaining available borrowing capacity were $669.2 million and $559.2 million, respectively, compared to $343.3 million and $215.8 million, respectively, as of December 31, 2013. The Bank’s FHLB borrowings as of September 30, 2014 and December 31, 2013 totaled $110.0 million and $127.5 million, respectively, which represented 2.60 percent and 4.17 percent of assets as of September 30, 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 $65.1 million from the Federal Reserve Discount Window, to which the Bank pledged loans with a carrying value of $89.4 million, and had no borrowings as of September 30, 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.

	Through our branch network and lending units, we provide a broad range of financial services to individuals and companies. These services include demand, time and savings deposits; and commercial and industrial, real estate and consumer lending. While our chief decision makers monitor the revenue streams of our various products and services, operations are managed and financial performance is evaluated on a company-wide basis. Accordingly, we consider all of our operations to be aggregated in one reportable operating segment.

Fair Value Measurements	'
	The estimated fair value of financial instruments has been determined by using available market information and appropriate valuation methodologies.

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.

	(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 0.48 year at September 30, 2014.
	(2)	Reflects two equity securities that are not actively traded. The fair value of one equity security with a fair value of $250,000 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. In addition to these approaches, the Company considered a discounted cash flow approach, which cash flows, calculated based on a redemption or liquidation policy of the equity issuer, are discounted back to the present using a 10.5% discount rate.
	(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. There were no outstanding stock warrants as of September 30, 2014. See “Note 9 – Stockholders’ Equity” for more details.
