Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Hanmi Financial Corporation (“Hanmi Financial,” the “Company,” “we,” “us” or “our”) is a bank holding company whose subsidiary is Hanmi Bank (the “Bank”). Our primary operations are related to traditional banking activities, including the acceptance of deposits and the lending and investing of money through the operation of the Bank. 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, 2019 , 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 unaudited consolidated financial statements are prepared in conformity with GAAP and 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 year ended December 31, 2018 (the “ 2018 Annual Report on Form 10-K”). The preparation of interim unaudited 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. These estimates and assumptions affect the amounts reported in the unaudited financial statements and disclosures provided, and actual results could differ. Descriptions of our significant accounting policies are included in Note 1 - Summary of Significant Accounting Policies in the Notes to consolidated financial statements in our 2018 Annual Report on Form 10-K. Effective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825) and ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220). Summaries of ASU 2016-01 and 2018-02 and the impact of their adoption are included in Notes 2 and 5 to the unaudited consolidated financial statements, respectively. In addition to other provisions, ASU 2016-01 requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. Beginning with the quarter ended March 31, 2018, the Company measured the fair value of certain financial instruments, included in Note 10 to the unaudited consolidated financial statements, using an exit price notion. The Company also adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as of January 1, 2018, as required. ASU 2014-09 replaces existing revenue recognition guidance for contracts to provide goods or services to customers and amends existing guidance related to recognition of gains and losses on the sale of certain nonfinancial assets such as real estate. See Note 13 to the accompanying unaudited consolidated financial statements for the impact of the adoption of this new standard on the Company's consolidated financial statements. Effective January 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842) , which requires lessees to recognize a right of use asset and a lease liability on their balance sheet for all leases, including operating leases, with a term of greater than 12 months. In July 2018, the FASB issued ASU 2018-11, which adds a transition option permitting entities to apply the provisions of the new standard at its adoption date instead of the earliest comparative period presented in the consolidated financial statements. Under this transition option, comparative reporting would not be required, and the provisions of the standard would be applied prospectively to leases in effect at the date of adoption. The Company elected to use the optional transition method provided by ASU 2018-11. The Company also elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed the Company to carry forward its ASC 840 assessment regarding definition of a lease, lease classification, and initial direct costs. The following practical expedients were applied during implementation of this standard: • We did not reassess whether any expired or existing contracts are, or contain, leases. Additionally, we did not reassess for lease classifications of expired or existing leases, or initial direct costs for any existing leases. • We applied incremental borrowing rates as of adoption date of January 1, 2019. • We elected to not separate non-lease components from lease components and, instead, to account for each separate lease component and the non-lease components associated with it as a single lease component recognized on the balance sheet. This election has been made for all classes of leases. • We elected the short-term lease exception, which allows us to account for leases with a lease term of twelve months or less to be accounted for similar to existing operating leases. The cost of these leases is disclosed, but is not recognized in the right-of-use asset and lease liability balances. Consistent with ASC 842 requirements, leases that are one month or less are not included in the disclosures. • We have elected to account for the leases under the portfolio approach applying them prospectively for this accounting change. The portfolio approach allows us to present multiple similar leased assets in a pool and prospectively allows us to commence the calculation of the portfolio of leases using the remaining commitments from adoption date forward. See Note 14 to the unaudited consolidated financial statements for the impact of the adoption of this new standard on the Company's consolidated financial statements. FASB ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , introduces new guidance for the accounting for credit losses on instruments within its scope. The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. Current expected credit losses (“CECL”) model, will apply to: (1) financial assets subject to credit losses and measured at amortized cost; and (2) certain off-balance sheet credit exposures. This includes loans, held-to-maturity debt securities, loan commitments, financial guarantees, and net investments in leases, as well as reinsurance and trade receivables. Upon initial recognition of the exposure, the CECL model requires an entity to estimate the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses (“ECL”) should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments. Financial instruments with similar risk characteristics should be grouped together when estimating ECL. ASU 2016-13 is effective for public entities for interim and annual periods beginning after December 15, 2019. On July 2, 2019, the FASB voted to delay CECL's effective date for non-public companies and Smaller Reporting Companies who are public filers. Due to the Company's categorization as a large accelerated filer, this delay will not have any impact on its adoption of ASU 2016-13. The Company has established a steering committee comprised of senior executives from the Accounting and Credit Risk functions and has engaged third party consultants to support CECL adoption activities. The Company is currently engaged in CECL implementation activities and has completed development of its methodologies, data/input gathering and validation, and initial testing of its designed models. The Company plans to leverage three loss rate methodologies across the Bank's four major loan and lease segments. The Company commenced parallel processing and review of the model outputs during the three-month period ended September 30, 2019. In addition, the Company has devised risk documentation and policies and procedures associated with CECL to support the ongoing estimation activities and the continuous assessment of risks related to the methodology and its models, and data governance. As of September 30, 2019, the Company continues to evaluate the impacts of ASU 2016-13 on its consolidated financial statements.

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, 2019 and December 31, 2018 . These securities have fluctuated in value since their purchase dates as market interest rates have fluctuated. The Company does not intend to sell these securities and it is more likely than not that it will not be required to sell the investments before the recovery of their amortized cost basis. 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, 2019 and December 31, 2018 were not other-than-temporarily impaired, and therefore, no impairment charges as of September 30, 2019 and December 31, 2018 were warranted. Realized gains and losses on sales of securities and proceeds from sales of securities were as follows for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 (in thousands) Gross realized gains on sales of securities $ — $ 19 $ 1,359 $ 87 Gross realized losses on sales of securities — — (64 ) (957 ) Net realized gains (losses) on sales of securities $ — $ 19 $ 1,295 $ (870 ) Proceeds from sales of securities $ — $ 3,426 $ 113,306 $ 34,751 In January 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825). This new guidance, among other provisions, amends accounting related to the classification and measurement of investments in equity securities. We adopted this guidance, as required, in the first quarter of 2018. ASU 2016-01 requires the amounts reported in accumulated other comprehensive income for equity securities that exist as of the date of adoption previously classified as available-for-sale be reclassified to retained earnings. The Company reduced the balance of securities by $529,000 as of January 1, 2018, representing the loss related to our mutual fund equity securities, which resulted in a net reduction of retained earnings of $382,000 and an increase of $147,000 in net deferred tax assets based on the transition requirements of this standard. During the three months ended September 30, 2019, there were no securities sales transactions. During the three months ended September 30, 2018 , there was $19,000 in net gain in earnings resulting from the sale of securities. A net unrealized gain of $21,000 related to these securities had previously been recorded in accumulated other comprehensive income as of the beginning of the period in 2018 . There was no sale of such securities during the nine months ended September 30, 2019. During the nine months ended September 30, 2019 , there was $1.3 million in net gains in earnings resulting from the sale of securities which had $586,000 in previously recorded unrealized gains in accumulated other comprehensive income. During the nine months ended September 30, 2018, there was a $870,000 net loss in earnings resulting from the sale of securities. In the first and second quarters of 2019, we sold all of our tax-exempt municipal bonds with a gross realized gain of $1.4 million . In the first quarter of 2018, we sold all of our mutual fund equity securities with gross realized losses of $957,000 . Securities available for sale with market values of $30.2 million and $29.9 million as of September 30, 2019 and December 31, 2018

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 loss experience; size, growth and composition of the loan and lease portfolio; the value of collateral; and current economic conditions. Our lending is concentrated generally in real estate loans, commercial loans and leases and SBA loans to small and middle market businesses primarily in California, Texas, Illinois and New York. Further, our regulators, in reviewing our loan and lease portfolio may require us to increase our allowance for loan and lease losses. The following table details the information on the allowance for loan and lease losses by portfolio segment as of and for the three months ended September 30, 2019 and 2018 : Real Estate Commercial and Industrial Leases Receivable Consumer Unallocated Total (in thousands) As of and for the Three Months Ended September 30, 2019 Allowance for loan and lease losses on loans and leases: Beginning balance $ 34,004 $ 9,235 6,068 $ 79 $ — $ 49,386 Less loans and leases charged off (17 ) (244 ) (653 ) (2 ) — (916 ) Recoveries on loans and leases previously charged off 142 381 117 — — 640 Loan and lease loss provision 2,272 (1,551 ) 886 (5 ) — 1,602 Ending balance $ 36,401 $ 7,821 $ 6,418 $ 72 $ — $ 50,712 Individually evaluated for impairment $ 14,781 $ 1,270 $ 1,049 $ 1 $ — $ 17,101 Collectively evaluated for impairment $ 21,620 $ 6,551 $ 5,369 $ 71 $ — $ 33,611 Loans and leases receivable: $ 3,646,327 $ 441,209 $ 467,777 $ 14,524 $ — $ 4,569,837 Individually evaluated for impairment $ 47,972 $ 13,692 $ 4,303 $ 1,325 $ — $ 67,292 Collectively evaluated for impairment $ 3,598,355 $ 427,517 $ 463,474 $ 13,199 $ — $ 4,502,545 Real Estate Commercial and Industrial Leases Receivable Consumer Unallocated Total (in thousands) As of and for the Three Months Ended September 30, 2018 Allowance for loan and lease losses on loans and leases: Beginning balance $ 17,916 $ 7,120 6,649 $ 109 $ 24 $ 31,818 Less loans and leases charged off (220 ) (232 ) (794 ) — — (1,246 ) Recoveries on loans and leases previously charged off 577 237 90 — — 904 Loan and lease loss provision (184 ) (38 ) 446 — (24 ) 200 Ending balance $ 18,089 $ 7,087 $ 6,391 $ 109 $ — $ 31,676 Individually evaluated for impairment $ 2,428 $ 631 $ 1,763 $ — $ — $ 4,822 Collectively evaluated for impairment $ 15,661 $ 6,456 $ 4,628 $ 109 $ — $ 26,854 Loans and leases receivable: $ 3,792,350 $ 396,383 $ 379,455 $ 14,695 $ — $ 4,582,883 Individually evaluated for impairment $ 20,596 $ 3,767 $ 5,093 $ 881 $ — $ 30,337 Collectively evaluated for impairment $ 3,771,754 $ 392,616 $ 374,362 $ 13,814 $ — $ 4,552,546 The following table details the information on the allowance for loan and lease losses by portfolio segment as of and for the nine months ended September 30, 2019 and 2018 : Real Estate Commercial and Industrial Leases Receivable Consumer Unallocated Total (in thousands) As of and for the Nine Months Ended September 30, 2019 Allowance for loan and lease losses on loans and leases: Beginning balance $ 18,384 $ 7,162 6,303 $ 98 $ 27 $ 31,974 Less loans and leases charged off (131 ) (939 ) (2,479 ) (1 ) 1 (3,549 ) Recoveries on loans and leases previously charged off 1,704 853 312 — — 2,869 Loan and lease loss provision 16,444 745 2,282 (25 ) (28 ) 19,418 Ending balance $ 36,401 $ 7,821 $ 6,418 $ 72 $ — $ 50,712 Individually evaluated for impairment $ 14,781 $ 1,270 $ 1,049 $ 1 $ — $ 17,101 Collectively evaluated for impairment $ 21,620 $ 6,551 $ 5,369 $ 71 $ — $ 33,611 Loans and leases receivable: $ 3,646,327 $ 441,209 $ 467,777 $ 14,524 $ — $ 4,569,837 Individually evaluated for impairment $ 47,972 $ 13,692 $ 4,303 $ 1,325 $ — $ 67,292 Collectively evaluated for impairment $ 3,598,355 $ 427,517 $ 463,474 $ 13,199 $ — $ 4,502,545 Real Estate Commercial and Industrial Leases Receivable Consumer Unallocated Total (in thousands) As of and for the Nine Months Ended Allowance for loan and lease losses on loans and leases: Beginning balance $ 17,012 $ 7,400 6,279 $ 122 $ 230 $ 31,043 Less loans and leases charged off (1,249 ) (597 ) (1,689 ) — — (3,535 ) Recoveries on loans and leases previously charged off 1,833 1,170 214 2 — 3,219 Loan and lease loss provision 493 (886 ) 1,587 (15 ) (230 ) 949 Ending balance $ 18,089 $ 7,087 $ 6,391 $ 109 $ — $ 31,676 Individually evaluated for impairment $ 2,428 $ 631 $ 1,763 $ — $ — $ 4,822 Collectively evaluated for impairment $ 15,661 $ 6,456 $ 4,628 $ 109 $ — $ 26,854 Loans and leases receivable: $ 3,792,350 $ 396,383 $ 379,455 $ 14,695 $ — $ 4,582,883 Individually evaluated for impairment $ 20,596 $ 3,767 $ 5,093 $ 881 $ — $ 30,337 Collectively evaluated for impairment $ 3,771,754 $ 392,616 $ 374,362 $ 13,814 $ — $ 4,552,546 Loan Quality Indicators As part of the on-going monitoring of the quality of our loan and lease portfolio, we utilize an internal loan and lease grading system to identify credit risk and assign an appropriate grade (from 0 to 8) for each loan or lease in our loan and lease portfolio. A third-party loan review is required on an annual basis. Additional adjustments are made when determined to be necessary. The loan and lease grade definitions are as follows: Pass and Pass-Watch: Pass and Pass-Watch loans and leases, 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 and lease grading system. It consists of all performing loans and leases with no identified credit weaknesses. It includes cash and stock/security secured loans or other investment grade loans. Special Mention: A Special Mention loan or lease, 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 and leases that have significant actual, not potential, weaknesses are considered more severely classified. Substandard: A Substandard loan or lease, grade (6), has a well-defined weakness that jeopardizes the liquidation of the debt. A loan or lease 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 or lease, there is a distinct possibility that the Bank will sustain some loss if the weaknesses or deficiencies are not corrected. Doubtful: A Doubtful loan or lease, 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 loan or lease, and therefore the amount or timing of a possible loss cannot be determined at the current time. Loss: A loan or lease classified as Loss, grade (8), is considered uncollectable and of such little value that their continuance as active bank assets is not warranted. This classification does not mean that the loan or lease 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 and leases classified as Loss will be charged off in a timely manner. Under regulatory guidance, loans and leases graded special mention or worse are considered criticized loans and leases, and loans and leases graded substandard or worse are considered classified loans and leases.

Impaired Loans and Leases Loans and leases are considered impaired when the Bank will be unable to collect all interest and principal payments per the contractual terms of the loan and lease agreement, unless the loan is well-collateralized and in the process of collection. Loans are classified as Troubled Debt Restructurings (“TDRs”) because, due to the financial difficulties of the borrowers, we have granted concessions to the borrowers we would not otherwise consider; when current information or events make it unlikely to collect in full according to the contractual terms of the loan or lease agreements; 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 and lease impairment in accordance with GAAP. Impaired loans and leases are measured based on the present value of expected future cash flows discounted at the receivable's effective interest rate or, as a practical expedient, at the receivable's observable market price or the fair value of the collateral if the loan or lease is collateral dependent, less estimated costs to sell. If the estimated value of the impaired loan or lease is less than the recorded investment in the loan or lease, the deficiency is either charged off against the allowance for loan and lease losses or we establish a specific reserve in the allowance for loan and lease losses. Additionally, loans and leases that are considered impaired are specifically excluded from the quarterly migration analysis when determining the amount of the allowance for loan and lease 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 and Leases and Nonperforming Assets Loans and leases 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 receivable is adequately collateralized and in the process of collection. However, in certain instances, we may place a particular loan or lease receivable on nonaccrual status earlier, depending upon the individual circumstances surrounding the delinquency. When a receivable 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 and leases may be restored to accrual status when principal and interest payments become current and full repayment is expected.

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, such as reducing the amount of principal and interest due monthly, and/or allowing for interest only monthly payments for three months or more or other payment structure modifications. 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. The allowance for loan and lease losses included $15.9 million of specific allowances at September 30, 2019 and $313,000 of specific allowances at December 31, 2018 relating to TDR loans. There were $44.0 million of commercial real estate loans ( eight loans), $12.6 million of commercial loans ( two loans) and one consumer loan for $0.5 million that were modified during the twelve-month period ended September 30, 2019. None of these loans defaulted no r were charged off subsequent to their restructuring during the twelve-month period ended September 30, 2019. The troubled debt restructurings described above increased the allowance by $15.7 million during the twelve-month period ended September 30, 2019. 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.

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 serviced were SBA loans. The Company recorded servicing fee income of $1.1 million and $1.2 million for the three months ended September 30, 2019 and 2018 , respectively. The Company recorded servicing fee income of $3.3 million and $3.5 million for the nine months ended September 30, 2019 and 2018 , respectively. Servicing fee income, net of the amortization of servicing assets and liabilities, is included in other operating income in the consolidated statements of income. Net amortization expense was $557,000 and $583,000 for the three months ended September 30, 2019 and 2018 , respectively, and $1.9 million and $2.0 million for the nine months ended September 30, 2019 and 2018 , respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s income tax expense was $4.3 million and $6.3 million representing an effective income tax rate of 25.9 percent and 28.0 percent for the three months ended September 30, 2019 and 2018 , respectively. The Company's income tax expense was $11.8 million and $17.9 million representing an effective income tax rate of 28.5 percent and 27.8 percent for the nine months ended September 30, 2019 and 2018 , respectively. Management concluded that as of September 30, 2019 and December 31, 2018 , a valuation allowance of $4.9 million was appropriate against certain state net operating losses and certain tax credits. For all other deferred tax assets, management believes it was more likely than not that these deferred tax assets will be realized principally through future taxable income and reversal of existing taxable temporary differences. A net deferred tax asset of $22.6 million and $27.4 million and a net current tax asset of $8.0 million and $8.3 million as of September 30, 2019 and December 31, 2018 , respectively, are included in prepaid expenses and other assets in the accompanying Consolidated Balance Sheets. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220) . This ASU eliminates the stranded tax effects in other comprehensive income resulting from the Tax Cuts and Jobs Act (the “Tax Act”). Because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations was not affected. ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The Company adopted this standard as of January 1, 2018, and recorded the impact as an adjustment which increased retained earnings by $399,000 as of the date of adoption. The Tax Act was enacted into U.S. tax law on December 22, 2017. The Tax Act makes numerous changes to the U.S. tax code, including (although not limited to) reducing the U.S. federal corporate tax rate to 21 percent, eliminating the corporate alternative minimum tax (AMT), limiting deductible interest expense, increasing limitations on certain executive compensation, and enhancing bonus depreciation to provide for full expensing of qualified property. On that same date, the SEC staff also issued SAB 118, which provided guidance regarding financial statement accounting of the tax effects of the Tax Act. SAB 118 provides for the completion of the accounting related effects of the Tax Act in accordance with a measurement period of one year from the Tax Act enactment date. The Company completed its accounting required under ASC 740 in 2018. The Company is subject to examination by various federal and state tax authorities for certain years ended December 31, 2014 through 2018. Management does not anticipate any material changes in our consolidated financial statements which may arise as a result of these audits or examinations. During the quarter ended March 31, 2019, the examination by the California Franchise Tax Board for the 2008 and 2009 tax years closed. The Company recorded a provision expense of $400,000 during the quarter ended March 31, 2019 in connection with both the release of an uncertain tax position and the settlement remitted, net of federal benefit. The Company paid $900,000 in connection with the settlement.

The Bank had $1.2 billion of loans pledged as collateral with the FHLB, which provides $1.0 billion in borrowing capacity, of which $769.6 million remained available at September 30, 2019 . The Bank also has securities with market values of $30.2 million pledged with the Federal Reserve Bank (“FRB”), which provides $29.6 million in available borrowing capacity through the Fed Discount Window. There were no outstanding borrowings with the FRB as of September 30, 2019 and December 31, 2018 . Subordinated Debentures The Company issued Fixed-to-Floating Subordinated Notes (the “Notes”) of $100.0 million on March 21, 2017, with a final maturity on March 30, 2027. The Notes have an initial fixed interest rate of 5.45% per annum, payable semi-annually on March 30 and September 30 of each year. From and including March 30, 2022 and thereafter, the Notes bear interest at a floating rate equal to the then current three-month LIBOR, as calculated on each applicable date of determination, plus 3.315% payable quarterly. If the then current three-month LIBOR is less than zero, three-month LIBOR will be deemed to be zero. Debt issuance cost was $2.3 million , which is being amortized through the Notes' maturity date. At September 30, 2019 and December 31, 2018 , the balance of Notes included in the Company's consolidated balance sheet, net of debt issuance cost, was $98.3 million and $98.1 million , respectively. The amortization of debt issuance cost was $49,000 and $46,000 for the three months ended September 30, 2019 and 2018 , respectively, and $144,000 and $136,000 for the nine months ended September 30, 2019 and 2018 , respectively. The Company assumed Junior Subordinated Deferrable Interest Debentures (“Subordinated Debentures”) as a result of the acquisition of Central Bancorp Inc. (“CBI”) in 2014 with an unpaid principal balance of $26.8 million and an estimated fair value of $18.5 million . The $8.3 million discount is being amortized to interest expense through the debentures' maturity date of March 15, 2036. CBI formed a trust in 2005 and issued $26.0 million of Trust Preferred Securities (“TPS”) at 6.26 percent fixed rate for the first five years and a variable rate at the three-month LIBOR plus 140 basis points thereafter and invested the proceeds in the Subordinated Debentures. The Company 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. At September 30, 2019 and December 31, 2018 , the balance of Subordinated Debentures included in the Company's consolidated balance sheets, net of discount of $6.9 million and $7.1 million , was $19.9 million and $19.7 million , respectively. The amortization of discount was $96,000 and $92,000 for the three months ended September 30, 2019 , and 2018 , respectively, and $280,000 and $264,000 for the nine months ended September 30, 2019 and 2018 , respectively.

Earnings Per Share [Abstract]
Earnings Per Share	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. For diluted EPS, weighted-average number of common shares includes the impact of unvested restricted stock under the treasury method. Unvested restricted stock containing rights to non-forfeitable dividends are considered participating securities prior to vesting and have been included in the earnings allocation in computing basic and diluted EPS under the two-class method. The following table is a reconciliation of the components used to derive basic and diluted EPS for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Basic EPS (dollars in thousands, except per share amounts) Net income $ 12,376 $ 16,081 $ 29,704 $ 46,484 Less: income allocated to unvested restricted stock 101 101 193 284 Income allocated to common shares $ 12,275 $ 15,980 $ 29,511 $ 46,200 Weighted-average shares for basic EPS 30,830,445 32,155,132 30,736,456 32,171,558 Basic EPS $ 0.40 $ 0.50 $ 0.96 $ 1.44 Effect of dilutive securities-options and unvested restricted stock 28,674 120,145 32,704 134,482 Diluted EPS Income allocated to common shares 12,275 15,980 29,511 46,200 Weighted-average shares for diluted EPS 30,859,119 32,275,277 30,769,160 32,306,041 Diluted EPS $ 0.40 $ 0.50 $ 0.96 $ 1.43 (1) Per share amounts may not be able to be recalculated using net income and weighted-average shares presented above due to rounding.

Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters 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 6.0 percent. 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 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 8.0 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. At September 30, 2019 , the Bank’s capital ratios exceeded the minimum requirements for the Bank to be considered “well capitalized” and the Company exceeded all of its applicable minimum regulatory capital ratio requirements. A capital conservation buffer of 2.5% became effective on January 1, 2019, and must be met to avoid limitations on the ability of the Bank to pay dividends, repurchase shares or pay discretionary bonuses. The Bank's capital conservation buffer was 6.65% and 6.19% and the Company's capital conservation buffer was 5.91% and 5.74% as of September 30, 2019 and December 31, 2018 , respectively.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair Value Measurements 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 securities available for sale at fair value on a recurring basis. Certain other assets, such as loans held for sale, impaired loans, OREO, and core deposit intangible, 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: Securities available for sale - The fair values of 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 securities include U.S. Treasury 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 securities primarily include U.S. government agency and sponsored agency mortgage-backed securities, collateralized mortgage obligations and debt securities as well as municipal bonds in markets that are 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 securities is determined based on pricing data provided by nationally recognized pricing services. 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 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. Loans held for sale - Loans held for sale are all SBA loans and carried at the lower of cost or fair value. 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, 2019 and December 31, 2018 , 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 - 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. All impaired loans with a carrying balance over $250,000 are reviewed individually for the amount of impairment, if any. Impaired loans with a carrying balance of $250,000 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. OREO - 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. Assets and Liabilities Measured at Fair Value on a Recurring Basis As of September 30, 2019 and December 31, 2018 , assets and liabilities measured at fair value on a recurring basis are as follows: Level 1 Level 2 Level 3 Quoted Prices in Active Markets for Identical Assets Significant Observable Inputs with No Active Market with Identical Characteristics Significant Unobservable Inputs Balance (in thousands) September 30, 2019 Assets: Securities available for sale: U.S. Treasury securities $ 40,169 $ — $ — $ 40,169 U.S. government agency and sponsored agency obligations: Mortgage-backed securities — 399,474 — 399,474 Collateralized mortgage obligations — 164,999 — 164,999 Debt securities — 17,173 — 17,173 Total U.S. government agency and sponsored agency obligations — 581,646 — 581,646 Municipal bonds-tax exempt — — — — Total securities available for sale $ 40,169 $ 581,646 $ — $ 621,815 December 31, 2018 Assets: Securities available for sale: U.S. Treasury securities $ 39,830 $ — $ — $ 39,830 U.S. government agency and sponsored agency obligations: Mortgage-backed securities — 295,034 — 295,034 Collateralized mortgage obligations — 122,292 — 122,292 Debt securities — 7,402 — 7,402 Total U.S. government agency and sponsored agency obligations — 424,728 — 424,728 Municipal bonds-tax exempt — 110,350 — 110,350 Total securities available for sale $ 39,830 $ 535,078 $ — $ 574,908 Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis As of September 30, 2019 and December 31, 2018 , assets and liabilities measured at fair value on a non-recurring basis are as follows: Level 1 Level 2 Level 3 Quoted Prices in Significant Significant Loss During the Nine Months Ended September 30, 2019 (in thousands) September 30, 2019 Assets: Impaired loans (1) $ — $ — $ 24,264 $ 15,948 OREO — — 330 — December 31, 2018 Assets: Impaired loans (2) $ — $ 3,253 $ 1,957 $ 1,184 OREO — 663 — — (1) Consist of real estate loans of $12.7 million and commercial and industrial loans of $11.5 million . (2) Consist of real estate loans of $3.5 million , commercial and industrial loans of $1.7 million . The fair value of the Level 3 impaired loans at September 30, 2019 were determined utilizing the fair value measurement methodology for assets measured on a non-recurring basis. The impaired loans measured at fair value at September 30, 2019 consisted of one commercial real estate loan with a fair value of $12.7 million and one commercial and industrial loan with a fair value of $11.5 million . The fair value of collateral dependent loans are determined on a non-recurring basis using either the sales comparison approach or the income approach by obtaining third party appraisals. ASC 825, Financial Instruments , 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. Effective January 1, 2018, the Company adopted ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825). This standard, among other provisions, requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. Other than certain financial instruments for which we have concluded that the carrying amounts approximate fair value, the fair value estimates shown below are based on an exit price notion as of September 30, 2019 , as required by ASU 2016-01. The financial instruments for which we have concluded that the carrying amounts approximate fair value include, cash and due from banks, accrued interest receivable and payable, and noninterest-bearing deposits. The fair values of off-balance sheet items 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. The estimated fair values of financial instruments were as follows: September 30, 2019 Carrying Fair Value Amount Level 1 Level 2 Level 3 (in thousands) Financial assets: Cash and due from banks $ 150,678 $ 150,678 $ — $ — Securities available for sale 621,815 40,169 581,646 — Loans held for sale 6,598 — 7,078 — Loans and leases receivable, net of allowance for loan and lease losses 4,519,125 — — 4,539,227 Accrued interest receivable 11,723 11,723 — — Financial liabilities: Noninterest-bearing deposits 1,388,121 — 1,388,121 — Interest-bearing deposits 3,302,020 — — 3,314,224 Borrowings and subordinated debentures 193,232 — 195,860 Accrued interest payable 10,076 10,076 — — December 31, 2018 Carrying Fair Value Amount Level 1 Level 2 Level 3 (in thousands) Financial assets: Cash and due from banks $ 155,376 $ 155,376 $ — $ — Securities available for sale 574,908 39,830 535,078 — Loans held for sale 9,390 — 9,905 — Loans and leases receivable, net of allowance for loan and lease losses 4,568,566 — — 4,518,716 Accrued interest receivable 13,331 13,331 — — Financial liabilities: Noninterest-bearing deposits 1,284,530 — 1,284,530 — Interest-bearing deposits 3,462,705 — — 3,458,523 Borrowings and subordinated debentures 172,808 — 98,020 54,939 Accrued interest payable 11,379 11,379 — —

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 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: September 30, 2019 December 31, 2018 (in thousands) Commitments to extend credit $ 346,182 $ 325,100 Standby letters of credit 32,585 32,500 Commercial letters of credit 6,380 13,848 Total undisbursed loan commitments $ 385,147 $ 371,448 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. Net adjustments to the allowance for off-balance sheet items are included in other operating expenses. Activity in the allowance for loan off-balance sheet items was as follows for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 (in thousands) Balance at beginning of period $ 1,333 $ 1,357 $ 1,439 $ 1,296 Provision (income) 209 — 103 61 Balance at end of period $ 1,542 $ 1,357 $ 1,542 $ 1,357

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as of January 1, 2018. ASU 2014-09 established a principles-based approach to recognizing revenue that applies to all contracts other than those covered by other authoritative U.S. GAAP guidance. Quantitative and qualitative disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows are also required. The standard’s core principle is that a company shall recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies generally are required to use more judgment and make more estimates than under prior guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. Since the guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under GAAP, the new guidance did not have an impact on revenue most closely associated with our financial instruments, including interest income and expense. The Company completed its overall assessment of revenue streams and review of related contracts potentially affected by the ASU, including revenue streams associated with our noninterest income. Based on this assessment, the Company concluded that ASU 2014-09 did not change the method in which the Company currently recognizes revenue for these revenue streams. The Company's noninterest income primarily includes service charges on deposit accounts, trade finance and other service charges and fees, servicing income, bank-owned life insurance income and gains or losses on sale of SBA loans and securities. Based on our assessment of revenue streams related to the Company's noninterest income, we concluded that the Company's performance obligations for such revenue streams are typically satisfied as services are rendered. If applicable, the Company records contract liabilities, or deferred revenue, when payments from customers are received or due in advance of providing services to customers and records contract assets when services are provided to customers before payment is received or before payment is due. The Company’s noninterest revenue streams are largely based on transactional activities and since the Company generally receives payments for its services during the period or at the time services are provided, there are no contract asset or receivable balances as of September 30, 2019 . Consideration is often received immediately or shortly after the Company satisfies its performance obligations and revenue is recognized.

Leases [Abstract]
Leases	Leases As described in Note 1 to the unaudited consolidated financial statements, the Company adopted ASU 2016-02, Leases (Topic 842), effective January 1, 2019. We had approximately 45 operating leases for real estate and other assets. These included various leases for our branch and office locations as well as those for postage and copier machines and an advertising billboard. Our leases had initial lease terms of two to twenty-five years . Most leases included one or more options to renew, with renewal terms that can extend the lease term from two to twelve years . We assessed these options using a threshold of reasonably certain. For leases where we were reasonably certain to renew, those option periods were included within the lease term and, therefore, the measurement of the right-of-use asset and lease liability. Certain leases included options to terminate the lease, which allows the contract parties to terminate their obligations under the lease contract, typically in return for an agreed financial consideration. The terms and conditions of the termination options vary by contract. Leases with an initial term of 12 months or less were not recognized on the balance sheet. We recognized lease expense for these leases on a straight-line basis over the lease term. Certain lease agreements included payments based on Consumer Price Index (CPI) on which variable lease payments were determined and included in the right-of-use asset and liability. Variable lease payments that were not based on CPI were excluded from the right-of-use asset and lease liability and recognized in the period in which the obligations for those payments were incurred. Our lease agreements did not contain any material residual value guarantees, restrictions or covenants. In determining whether a contract contained a lease, we determined whether an arrangement was or included a lease at contract inception. Operating lease right-of-use asset and liability were recognized at commencement date and initially measured based on the present value of lease payments over the defined lease term. The opening balance for both our right-of-use asset and lease liability were $40.9 million as of the adoption date of January 1, 2019 and the outstanding balances were $38.2 million and $38.8 million , respectively, as of September 30, 2019 . We had real estate lease agreements with lease and non-lease components, which are generally accounted for separately. However, we elected the practical expedient to not separate non-lease components from lease components for all classes of underlying assets. For certain equipment leases, such as machine equipment, we accounted for the lease and associated non-lease components as a single lease component. In determining the discount rates, since most of our leases do not provide an implicit rate, we used our incremental borrowing rate provided by the FHLB of San Francisco based on the information available at commencement date to calculate the present value of lease payments. In order to apply the incremental borrowing rate, a portfolio approach with a collateralized rate was utilized. Assets were grouped based on similar lease terms and economic environments in a manner whereby the Company reasonably expects that the application does not differ materially from a lease-by-lease approach. The following table presents the Company's right-of-use asset and lease liability for the period indicated: September 30, 2019 (in thousands) Assets Total right-of-use assets - Operating leases $ 38,211 Liabilities Total lease liabilities - Operating leases $ 38,767 The Company's right-of-use asset is included in prepaid expenses and other assets and our lease liability is included in accrued expenses and other liabilities in the accompanying consolidated balance sheet. The following table presents the Company's lease costs for the periods indicated: Three Months Ended Nine Months Ended (in thousands) Operating lease cost (1) $ 2,089 $ 5,956 Sublease income (2) (33 ) (99 ) Net lease cost $ 2,056 $ 5,857 (1) Includes short-term leases and variable lease costs, which are recorded in rent expense. (2) Includes rental income from leased properties, which are included as contra-expense in rent expense. The following table presents the Company's remaining lease liability by maturity as of September 30, 2019 : Operating Leases (in thousands) 2019 $ 1,902 2020 6,374 2021 5,129 2022 4,843 2023 4,735 Thereafter 21,727 44,710 Interest (5,943 ) Present value of lease liability $ 38,767 Weighted average remaining leases terms for the Company's operating leases were 8.63 years as of September 30, 2019 . Weighted average discount rates used for the Company's operating leases was 3.24 percent as of September 30, 2019 . Net lease expense recognized for the three and nine months ended September 30, 2019 was $2.1 million and $5.9 million , respectively. The Company chose the practical expedients and reviewed the lease and non-lease components for any impairment or otherwise, subsequently determining that no cumulative-effect adjustment to equity was necessary as part of implementing the modified retrospective approach for its adoption of ASC 842 . Cash paid, and included in cash flows from operating activities, for amounts included in the measurement of the lease liability for the Company's operating leases for the three and nine months ended September 30, 2019 was $1.9 million and $5.3 million , respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	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, 2019 , 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 unaudited consolidated financial statements are prepared in conformity with GAAP and 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 year ended December 31, 2018 (the “ 2018 Annual Report on Form 10-K”).
Use of Estimates	The preparation of interim unaudited 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. These estimates and assumptions affect the amounts reported in the unaudited financial statements and disclosures provided, and actual results could differ.
Recent Accounting Pronouncements	Descriptions of our significant accounting policies are included in Note 1 - Summary of Significant Accounting Policies in the Notes to consolidated financial statements in our 2018 Annual Report on Form 10-K. Effective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825) and ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220). Summaries of ASU 2016-01 and 2018-02 and the impact of their adoption are included in Notes 2 and 5 to the unaudited consolidated financial statements, respectively. In addition to other provisions, ASU 2016-01 requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. Beginning with the quarter ended March 31, 2018, the Company measured the fair value of certain financial instruments, included in Note 10 to the unaudited consolidated financial statements, using an exit price notion. The Company also adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as of January 1, 2018, as required. ASU 2014-09 replaces existing revenue recognition guidance for contracts to provide goods or services to customers and amends existing guidance related to recognition of gains and losses on the sale of certain nonfinancial assets such as real estate. See Note 13 to the accompanying unaudited consolidated financial statements for the impact of the adoption of this new standard on the Company's consolidated financial statements. Effective January 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842) , which requires lessees to recognize a right of use asset and a lease liability on their balance sheet for all leases, including operating leases, with a term of greater than 12 months. In July 2018, the FASB issued ASU 2018-11, which adds a transition option permitting entities to apply the provisions of the new standard at its adoption date instead of the earliest comparative period presented in the consolidated financial statements. Under this transition option, comparative reporting would not be required, and the provisions of the standard would be applied prospectively to leases in effect at the date of adoption. The Company elected to use the optional transition method provided by ASU 2018-11. The Company also elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed the Company to carry forward its ASC 840 assessment regarding definition of a lease, lease classification, and initial direct costs. The following practical expedients were applied during implementation of this standard: • We did not reassess whether any expired or existing contracts are, or contain, leases. Additionally, we did not reassess for lease classifications of expired or existing leases, or initial direct costs for any existing leases. • We applied incremental borrowing rates as of adoption date of January 1, 2019. • We elected to not separate non-lease components from lease components and, instead, to account for each separate lease component and the non-lease components associated with it as a single lease component recognized on the balance sheet. This election has been made for all classes of leases. • We elected the short-term lease exception, which allows us to account for leases with a lease term of twelve months or less to be accounted for similar to existing operating leases. The cost of these leases is disclosed, but is not recognized in the right-of-use asset and lease liability balances. Consistent with ASC 842 requirements, leases that are one month or less are not included in the disclosures. • We have elected to account for the leases under the portfolio approach applying them prospectively for this accounting change. The portfolio approach allows us to present multiple similar leased assets in a pool and prospectively allows us to commence the calculation of the portfolio of leases using the remaining commitments from adoption date forward. See Note 14 to the unaudited consolidated financial statements for the impact of the adoption of this new standard on the Company's consolidated financial statements. FASB ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , introduces new guidance for the accounting for credit losses on instruments within its scope. The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. Current expected credit losses (“CECL”) model, will apply to: (1) financial assets subject to credit losses and measured at amortized cost; and (2) certain off-balance sheet credit exposures. This includes loans, held-to-maturity debt securities, loan commitments, financial guarantees, and net investments in leases, as well as reinsurance and trade receivables. Upon initial recognition of the exposure, the CECL model requires an entity to estimate the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses (“ECL”) should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments. Financial instruments with similar risk characteristics should be grouped together when estimating ECL. ASU 2016-13 is effective for public entities for interim and annual periods beginning after December 15, 2019. On July 2, 2019, the FASB voted to delay CECL's effective date for non-public companies and Smaller Reporting Companies who are public filers. Due to the Company's categorization as a large accelerated filer, this delay will not have any impact on its adoption of ASU 2016-13. The Company has established a steering committee comprised of senior executives from the Accounting and Credit Risk functions and has engaged third party consultants to support CECL adoption activities. The Company is currently engaged in CECL implementation activities and has completed development of its methodologies, data/input gathering and validation, and initial testing of its designed models. The Company plans to leverage three loss rate methodologies across the Bank's four major loan and lease segments. The Company commenced parallel processing and review of the model outputs during the three-month period ended September 30, 2019. In addition, the Company has devised risk documentation and policies and procedures associated with CECL to support the ongoing estimation activities and the continuous assessment of risks related to the methodology and its models, and data governance. As of September 30, 2019, the Company continues to evaluate the impacts of ASU 2016-13 on its consolidated financial statements.
Fair Value Assumptions of Financial Instruments	The following methods and assumptions were used to estimate the fair value of each class of financial instrument below: Securities available for sale - The fair values of 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 securities include U.S. Treasury 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 securities primarily include U.S. government agency and sponsored agency mortgage-backed securities, collateralized mortgage obligations and debt securities as well as municipal bonds in markets that are 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 securities is determined based on pricing data provided by nationally recognized pricing services. 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 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. Loans held for sale - Loans held for sale are all SBA loans and carried at the lower of cost or fair value. 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, 2019 and December 31, 2018 , 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 - 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. All impaired loans with a carrying balance over $250,000 are reviewed individually for the amount of impairment, if any. Impaired loans with a carrying balance of $250,000 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. OREO - 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.
Fair Value Measurements	ASC 825, Financial Instruments , 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. Effective January 1, 2018, the Company adopted ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825). This standard, among other provisions, requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. Other than certain financial instruments for which we have concluded that the carrying amounts approximate fair value, the fair value estimates shown below are based on an exit price notion as of September 30, 2019 , as required by ASU 2016-01. The financial instruments for which we have concluded that the carrying amounts approximate fair value include, cash and due from banks, accrued interest receivable and payable, and noninterest-bearing deposits. The fair values of off-balance sheet items 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.
