Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations First Choice Bancorp, headquartered in Cerritos, California, is a California corporation that was incorporated on September 1, 2017 and is the registered bank holding company for First Choice Bank. Incorporated in March 2005 and commencing commercial bank operations in August 2005, First Choice Bank is a California-chartered member bank. References herein to “First Choice Bancorp,” “Bancorp” or the “holding company,” refer to First Choice Bancorp on a stand-alone basis. The words “we," "us," "our," or the "Company" refer to First Choice Bancorp and First Choice Bank collectively and on a consolidated basis. References to the “Bank” refer to First Choice Bank on a stand-alone basis. Headquartered in Cerritos, California, the Bank is a community-based financial institution that serves commercial and consumer clients in diverse communities. The Bank specializes in loans to small- to medium-sized businesses and private banking clients, commercial and industrial loans, and commercial real estate loans with a specialization in providing financial solutions for the hospitality industry. The Bank is a Preferred Small Business Administration (“SBA”) Lender. The Bank conducts business through 9 full-service branches and 2 loan production offices located in Los Angeles, Orange and San Diego Counties. Effective May 17, 2019, the Little Tokyo branch was closed and consolidated with the 6th and Figueroa branch located in downtown Los Angeles and the San Diego branch operations were consolidated into the Carlsbad branch. The San Diego location remains as a loan production office. Effective July 31, 2018, we acquired Pacific Commerce Bancorp (“PCB”) and its wholly-owned subsidiary bank, Pacific Commerce Bank, by merger in an all-stock transaction. The acquisition has been accounted for using the acquisition method of accounting and, accordingly, the operating results of PCB have been included in the consolidated financial statements since August 1, 2018. As a California-chartered member bank, the Bank is primarily regulated by the California Department of Business Oversight (the “DBO”) and the Board of Governors of the Federal Reserve System (the “FRB”). The Bank’s deposits are insured up to the maximum legal limit by the Federal Deposit Insurance Corporation (the “FDIC”). First Choice Bancorp's stock is traded on the Nasdaq Capital Market under the ticker symbol “FCBP.” Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of Bancorp and the Bank and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the instructions to Form 10-Q and Article 10 of Regulation S-X for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments considered necessary for a fair presentation, have been included. Operating results for the nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. These interim period condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements as of and for the years ended December 31, 2018 and 2017 , which are included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (the "SEC"). All significant intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to the condensed consolidated income statement for the three and nine months ended September 30, 2018 to conform to the September 30, 2019 presentation. For the three and nine months ended September 30, 2018 , these reclassifications include: (i) $97 thousand and $289 thousand of stock-based compensation expense for stock options and restricted stock awards for directors that were previously reported in salaries and employee benefits expense and are now included in other expenses; and (ii) $7 thousand and $21 thousand of rental income that were previously reported in occupancy and equipment expense and are now included in other income. Use of Estimates in the Preparation of Consolidated Financial Statements The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change are the determination of the allowance for loan losses, the valuation of acquired loans, the valuation of goodwill and separately identifiable intangible assets associated with mergers and acquisitions, and the valuation of deferred tax assets. Accounting Policies Except for the update to reflect the impact of the adoption of ASU 2016-02, Leases (Topic 842) effective January 1, 2019, discussed below, there were no significant changes to our accounting policies from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2018 under the section entitled "Summary of Critical Accounting Policies," and Note 1 - Basis of Presentation and Summary of Significant Accounting Policies to the audited consolidated financial statements included therewith. Leases We determine if an arrangement contains a lease at contract inception and recognize a right-of-use ("ROU") asset and operating lease liability based on the present value of lease payments over the lease term. While our operating leases may include options to extend the term, these options are not included when calculating the ROU asset and lease liability unless we are reasonably certain we will exercise such options. Most of our leases do not provide an implicit rate and, therefore, we determine the present value of lease payments by using our incremental borrowing rate, currently our FHLB secured borrowing rate for the remaining lease term, and other information available at lease commencement. Leases with an initial term of 12 months or less are not recorded in the consolidated balance sheets. Lease expense is recognized on a straight line basis over the lease term. We have lease agreements with lease and non-lease components for which we have elected to account for as a single lease component. Refer to – Accounting Standards Adopted in 2019 below and Note 6. Leases for further discussion on our leasing arrangements and related accounting. Accounting Standards Adopted in 2019 We adopted ASU 2016-02, Leases (Topic 842) and ASU 2018-11, Leases (Topic 842): Targeted Improvements, referred to herein as Topic 842, effective January 1, 2019. The new guidance establishes the principles to report transparent and economically neutral information about the assets and liabilities that arise from leases. Entities are required to recognize ROU assets and lease liabilities that arise from leases in the statement of financial position and to disclose qualitative and quantitative information about lease transactions, such as information about variable lease payments and options to renew and terminate leases. Under the amendments in ASU 2018-11, entities may elect not to recast the comparative periods presented when transitioning to the new leasing standard. Upon adoption, we elected to use the modified retrospective transition approach and recorded ROU assets of $6.0 million and lease liabilities of $6.1 million at the date of adoption with no adjustment to opening equity. We elected to apply the package of practical expedients which permits entities to not reassess: (i) whether any expired or existing contracts contain a lease; (ii) lease classification for any expired or existing leases; and (iii) whether initial direct costs for any existing leases qualify for capitalization under the amended guidance. We also elected not to include short-term leases (leases with initial terms of 12 months or less) on the consolidated balance sheets. Recent Accounting Guidance Not Yet Effective In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326) (“ASU 2016-13”), also known as "CECL". This guidance will replace the incurred loss impairment methodology used to estimate the allowance for credit losses in current GAAP with a methodology that reflects future expected credit losses and requires consideration of a broader range of reasonable and supportable forecasts in the credit loss estimates. On October 16, 2019, the FASB decided to delay the effective date of ASU 2016-13 for smaller reporting companies, private companies and other non-SEC filers. We are considered a smaller reporting company. Therefore, this ASU will be effective for the Company on January 1, 2023 with early adoption permitted. Management continues to have a cross functional committee in place to oversee the project, has selected software to implement the new guidance, and has engaged an existing third-party service provider to assist in implementation. We have completed data gap analyses, developed initial modeling assumptions, and run a high level sensitivity analysis. We expect to run parallel calculations, testing, and further sensitivity analysis beginning in the first quarter of 2020. We have not yet determined the potential impact of the adoption of ASU 2016-13 to our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the current goodwill impairment test. Step 2 currently measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, under the amendments in ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. On October 16, 2019, the FASB decided to delay the effective date of ASU 2017-04 for smaller reporting companies, private companies and other non-SEC filers. We are considered a smaller reporting company. Therefore, this ASU will be effective for the Company on January 1, 2023. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We do not expect the adoption of ASU 2017-04 to have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13"). The primary objective of ASU 2018-13 is to improve the effectiveness of disclosures in the notes to financial statements. ASU 2018-13 will be effective on January 1, 2020, although early adoption is permitted. The adoption of ASU 2018-13 is not expected to significantly impact our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) ("ASU 2018-15"). ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). ASU 2018-15 will be effective on January 1, 2020, including interim periods within the years of adoption although early adoption is permitted. ASU 2018-15 is not expected to significantly impact our condensed consolidated financial statements.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	GOODWILL AND INTANGIBLE ASSETS In connection with the acquisition of PCB, we recognized goodwill of $73.4 million and a core deposit intangible ("CDI") of $6.9 million on July 31, 2018. There were no changes in the carrying amount of goodwill during 2019 and 2018 . For the three and nine months ended September 30, 2019 , we recognized CDI amortization of $197 thousand and $590 thousand and $133 thousand for the three and nine months ended September 30, 2018 . No impairment was recognized.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	INVESTMENT SECURITIES Investment securities have been classified in the condensed consolidated balance sheets according to management’s intent to either hold them to maturity or make them available for sale. The carrying amount of securities held-to-maturity and securities available-for-sale and their approximate fair values at September 30, 2019 and December 31, 2018 were as follows: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value September 30, 2019 (dollars in thousands) Securities available-for-sale: Mortgage-backed securities $ 8,057 $ 25 $ (104 ) $ 7,978 Collateralized mortgage obligations 10,293 46 (33 ) 10,306 SBA pools 8,937 133 (10 ) 9,060 $ 27,287 $ 204 $ (147 ) $ 27,344 Securities held-to-maturity: U.S. Government and agency securities $ 3,342 $ — $ (1 ) $ 3,341 Mortgage-backed securities 1,724 60 (15 ) 1,769 $ 5,066 $ 60 $ (16 ) $ 5,110 December 31, 2018 Securities available-for-sale: Mortgage-backed securities $ 9,177 $ — $ (333 ) $ 8,844 Collateralized mortgage obligations 11,731 2 (272 ) 11,461 SBA pools 9,628 — (390 ) 9,238 $ 30,536 $ 2 $ (995 ) $ 29,543 Securities held-to-maturity: U.S. Government and agency securities $ 3,340 $ — $ (122 ) $ 3,218 Mortgage-backed securities 1,982 — (105 ) 1,877 $ 5,322 $ — $ (227 ) $ 5,095 The amortized cost and estimated fair value of all investment securities held-to-maturity and available-for-sale at September 30, 2019 , by contractual maturities are shown below. Contractual maturities may differ from expected maturities because the obligors and/or issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

At September 30, 2019 and December 31, 2018 , there were no holdings of securities of any one issuer in an amount greater than 10% of our shareholders’ equity. There were no purchases, sales, maturities or calls of any investment securities available-for-sale or held-to-maturity during the three and nine months ended September 30, 2019 . There were $1.2 million in sales and $1.2 million in purchases of investment securities available-for-sale during the three and nine months ended September 30, 2018 and no maturities or calls of any investment securities available-for-sale or held-to-maturity during the same period of 2018 . At September 30, 2019 securities held-to-maturity with a carrying amount of $5.1 million were pledged to the Federal Reserve Bank as discussed in Note 8 – Borrowing Arrangements . As of September 30, 2019 and December 31, 2018 , unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, are summarized as follows: Less Than Twelve Months Over Twelve Months Total Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value September 30, 2019 (dollars in thousands) Securities available-for-sale: Mortgage-backed securities $ — $ — $ (104 ) $ 6,525 $ (104 ) $ 6,525 Collateralized mortgage obligations — — (33 ) 2,347 (33 ) 2,347 SBA pools (10 ) 3,144 — — (10 ) 3,144 $ (10 ) $ 3,144 $ (137 ) $ 8,872 $ (147 ) $ 12,016 Securities held-to-maturity: U.S. Government and agency securities $ (1 ) $ 3,341 $ — $ — $ (1 ) $ 3,341 Mortgage-backed securities — — (15 ) 795 (15 ) 795 $ (1 ) $ 3,341 $ (15 ) $ 795 $ (16 ) $ 4,136 December 31, 2018 Securities available-for-sale: Mortgage-backed securities $ (20 ) $ 2,397 $ (313 ) $ 6,447 $ (333 ) $ 8,844 Collateralized mortgage obligations (3 ) 1,127 (269 ) 9,742 (272 ) 10,869 SBA pools — — (390 ) 9,238 (390 ) 9,238 $ (23 ) $ 3,524 $ (972 ) $ 25,427 $ (995 ) $ 28,951 Securities held-to-maturity: U.S. Government and agency securities $ — $ — $ (122 ) $ 3,218 $ (122 ) $ 3,218 Mortgage-backed securities — — (105 ) 1,877 (105 ) 1,877 $ — $ — $ (227 ) $ 5,095 $ (227 ) $ 5,095 At September 30, 2019 , we had 13 investment securities in an unrealized loss position with total unrealized losses of $163 thousand . Such unrealized losses on these investment securities have not been recognized into income. We do not believe these unrealized losses are other-than-temporary because the issuers’ bonds are above investment grade, the decline in fair value is largely due to changes in interest rates, and management does not intend to sell these securities nor is it more likely than not that management would be required to sell the securities prior to their anticipated recovery. Equity Securities with a Readily Determinable Fair Value At September 30, 2019 and December 31, 2018 , equity securities with a readily determinable fair value of $2.7 million and $2.5 million represent a mutual fund investment consisting of high quality debt securities and other debt instruments supporting domestic affordable housing and community development. With the adoption of ASU 2016-01 on January 1, 2018, we recorded a transition adjustment to reclassify $24 thousand in net unrealized losses from accumulated other comprehensive income to retained earnings for these investments. In addition, we recognized net gains of $14 thousand and net losses of $23 thousand related to changes in fair value during the three months ended September 30, 2019 and 2018 , all of which related to equity securities held during those periods. During the nine months ended September 30, 2019 and 2018 , we recognized net gains of $88 thousand and net losses of $94 thousand related to changes in fair value. Restricted Stock and Other Bank Stock Investments The Bank is a member of the FHLB system. Members are required to own FHLB stock of the greater of 1% of FHLB membership asset value or 2.7% of outstanding FHLB advances. At September 30, 2019 and December 31, 2018 , the Bank owned $6.1 million of FHLB stock which is carried at cost. During the three and nine months ended September 30, 2019 , there were no required purchases of FHLB stock. We evaluated the carrying value of our FHLB stock investment at September 30, 2019 and determined that it was not impaired. This evaluation considered the long-term nature of the investment, the current financial and liquidity position of the FHLB, repurchase activity of excess stock by the FHLB at its carrying value, the return on the investment from recurring and special dividends, and our intent and ability to hold this investment for a period of time sufficient to recover our recorded investment. As a member of the Board of Governors of the Federal Reserve System ("FRB"), the Bank owned $6.8 million and $6.7 million of FRB stock, which is carried at cost, at September 30, 2019 and December 31, 2018 . The Bank purchased $43 thousand and $115 thousand of FRB stock during the three and nine months ended September 30, 2019 . We evaluated the carrying value of our FRB stock investment at September 30, 2019 and determined that it was not impaired. This evaluation considered the long-term nature of the investment, the current financial and liquidity position of the FRB, repurchase activity of excess stock by the FRB at its carrying value, the return on the investment from recurring dividends, and our intent and ability to hold this investment for a period of time sufficient to recover our recorded investment. The Bank also has restricted securities in the form of capital stock invested in two different banker’s bank stocks (collectively "Other Bank Stocks") which totaled $1.0 million at September 30, 2019 and December 31, 2018 and are reported in other assets in the condensed consolidated balance sheets. During the three and nine months ended September 30, 2019 , there were no changes in the fair value of these equity securities. There was no loss recognized related to changes in the fair value of these equity securities during the three months ended September 30, 2018 and a $46 thousand loss related to changes in the fair value of these equity securities for the nine months ended September 30, 2018 .

Receivables [Abstract]
Loans	LOANS Our loan portfolio consists primarily of loans to borrowers within our principal market area which includes Los Angeles County, Orange County and San Diego County, California. Although we seek to avoid concentrations of loans to a single industry or based upon a single class of collateral, real estate and real estate associated businesses, such as hospitality businesses, are among the principal industries in our market area and, as a result, our loan and collateral portfolios are, to some degree, concentrated in those industries. We also originate SBA loans either for sale to institutional investors or to hold in the loan portfolio. Loans identified as held for sale are carried at the lower of their net carrying value or market value and separately designated as such in the condensed consolidated financial statements. A portion of our revenues are from origination of loans guaranteed by the SBA under its various programs and sale of the guaranteed portions of the loans. Funding for these loans depends on annual appropriations by the U.S. Congress. As of September 30, 2019 , we had certain qualifying loans with an unpaid principal balance of $879.1 million pledged as collateral under a secured borrowing arrangement with the FHLB, and $226.9 million of loans with an unpaid principal balance pledged as collateral under a secured borrowing arrangement with the FRB. See Note 8 – Borrowing Arrangements for additional information regarding the FHLB and FRB secured lines of credit. The loans held for investment portfolio includes originated and acquired loans. The acquired loans includes: (i) loans that were not credit impaired on the date of acquisition; and (ii) purchased credit impaired ("PCI") loans, which are defined as loans with evidence of credit deterioration since their originations and for which it is probable that collection of all contractually required payments are unlikely as of the acquisition date.

(2) Unamortized net discounts include discounts related to the retained portion of SBA loans and net discounts on Non-PCI acquired loans. At September 30, 2019 , net discounts related to loans acquired in the PCB acquisition totaled $7.6 million and are expected to be accreted into interest income over a weighted average life of 5.1 years . At December 31, 2018, net discounts related to loans acquired in the PCB acquisition totaled $9.5 million .

We analyze loans individually by classifying the loans as to credit risk. This analysis typically includes larger, non-homogeneous loans such as commercial real estate and commercial and industrial loans. This analysis is performed on an ongoing basis as new information is obtained. We use the following definitions for risk ratings: Pass - Loans classified as pass represent assets with a level of credit quality which contain no well-defined deficiency or weakness. Special Mention - Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard - Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful - Loans classified as doubtful have all the weaknesses inherent in those classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full, based on currently known facts, conditions and values, highly questionable and improbable.

Transfers and Servicing [Abstract]
Transfers and Servicing of Financial Assets	TRANSFERS AND SERVICING OF FINANCIAL ASSETS We sell loans in the secondary market and, for certain loans, retain the servicing responsibility. The loans serviced for others are accounted for as sales and, therefore, are not included in the accompanying condensed consolidated balance sheets. Loans serviced for others totaled $295.7 million and $288.2 million at September 30, 2019 and December 31, 2018 . This includes SBA loans serviced for others of $213.5 million at September 30, 2019 and $198.4 million at December 31, 2018 for which there is a related servicing asset of $3.4 million and $3.2 million . In addition, the loan servicing portfolio includes construction and land development loans, commercial real estate loans and commercial & industrial loans participated with various other institutions of $82.2 million and $89.8 million at September 30, 2019 and December 31, 2018 for which there is no related servicing asset. Consideration for each SBA loan sale includes the cash received and a related servicing asset. We receive servicing fees ranging from 0.25% to 1.00% for the services provided over the life of the loan. The servicing asset is based on the estimated fair value of these future cash flows to be collected. The risk inherent in the SBA servicing asset primarily relates to accelerated prepayment of loans in excess of what was originally modeled driven by changes in interest rates and a reduction in the estimated future cash flows. The servicing asset activity includes additions from loan sales with servicing retained and reductions from amortization as the serviced loans are repaid and servicing fees are earned. The SBA servicing asset activity is summarized for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 (dollars in thousands) Balance, beginning of period $ 3,482 $ 2,448 $ 3,186 $ 2,618 Additions (1) 170 1,111 883 1,297 Amortization (282 ) (397 ) (699 ) (753 ) Balance, end of period $ 3,370 $ 3,162 $ 3,370 $ 3,162 (1) For the three and nine months ended September 30, 2018 , additions included the servicing asset fair value of $1.1 million from the PCB acquisition on July 31, 2018. The fair value of the servicing asset for SBA loans is measured at least quarterly and was $3.3 million and $3.3 million as of September 30, 2019 and December 31, 2018 . The significant assumptions used in the valuation of the SBA servicing asset at September 30, 2019 included discount rates, ranging from 6.8% to 35.3% , and a weighted average prepayment speed assumption of 17.9% . The following table summarizes the estimated change in the value of servicing assets as of September 30, 2019 given hypothetical shifts in prepayments speeds and yield assumptions: Change in Assumption Change in Estimated Fair Value (dollars in thousands) Prepayment speeds +10% $ (179 ) Prepayment speeds +20% (341 ) Discount rate +1% (88 ) Discount rate +2% (172 ) During the three months ended September 30, 2019 and 2018 , SBA loans sold totaled $9.7 million and $2.4 million resulting in total gains on sale of SBA loans of $528 thousand and $171 thousand . During the nine months ended September 30, 2019 and 2018 , SBA loans sold totaled $44.7 million and $11.2 million resulting in total gains of $2.7 million and $866 thousand . Net servicing fees, a component of noninterest income, represent contractually specified servicing fees reported net of the servicing asset amortization. Net servicing fees totaled $242 thousand and $39 thousand for the three months ended September 30, 2019 and 2018 including contractually specified servicing fees of $524 thousand and $435 thousand , offset by the amortization indicated in the table above. Net servicing fees totaled $763 thousand and $318 thousand for the nine months ended September 30, 2019 and 2018 , including contractually specified servicing fees of $1.5 million and $1.1 million , offset by the amortization indicated in the table above.

Leases [Abstract]
Leases	LEASES We adopted ASU 2016-02, Leases (Topic 842), and related amendments on January 1, 2019, using the modified retrospective transition method whereby comparative periods were not restated. No cumulative effect adjustment to the opening balance of retained earnings was required. We elected the package of practical expedients permitted under the new standard as described in Note 1 - Basis of Presentation and Summary of Significant Accounting Policies - Accounting Standards Adopted in 2019. All of our leases are operating leases for corporate offices, branch locations and loan production offices. The amount of the lease liability and ROU asset is impacted by the lease term and the discount rate applied to determine the present value of future lease payments. The remaining terms of our operating leases range from 9 months to 5.3 years . Most of our leases include one or more options to renew, with renewal terms that can extend the lease term by varying amounts. The exercise of renewal options is at our sole discretion. We do not include renewal options in the measurement of ROU assets and lease liabilities unless they are considered reasonably certain of exercise. Upon adoption of this standard, we recognized ROU assets of $6.0 million and lease liabilities of $6.1 million . Subsequent to adoption, we recognized a $220 thousand impairment of the ROU assets related to the consolidation of two branches. The impairment of the ROU assets was based on a discounted cash flow of estimated sublease income over the remaining lease term. The balance of ROU assets, net of impairment, and lease liabilities are included in other assets and other liabilities on the condensed consolidated balance sheets. In addition to the ROU impairment related to the branch consolidations, we recognized an $180 thousand impairment of other long lived assets; both impairment charges are included in occupancy and equipment expense on the condensed consolidated statements of income. The balance sheet and supplemental information at September 30, 2019 are shown below. Balance Sheet and Supplemental Information (dollars in thousands) Operating lease ROU assets classified as other assets $5,456 Operating lease liability classified as other liabilities $5,714 Weighted average remaining lease term, in years 3.1 Weighted average discount rate 2.52 % We elected not to separate lease and non-lease components and instead to account for them as a single lease component. Variable lease cost primarily represents variable payments such as common area maintenance and utilities. The following table represents lease costs and other lease information for the periods indicated: Three Months Ended September 30, 2019 Nine Months Ended (dollars in thousands) Lease Costs Operating lease cost $ 543 $ 1,629 Variable lease cost 47 103 Short-term lease cost 3 17 Total lease costs $ 593 $ 1,749 Other Information Cash paid for amounts included in the measurement of lease liabilities $ 553 $ 1,673 Maturities of lease liabilities for periods indicated: Twelve Months Ended September 30, (dollars in thousands) 2020 $ 2,113 2021 1,715 2022 1,518 2023 422 2024 139 Thereafter 35 Total future minimum lease payments 5,942 Less: Imputed interest (228 ) Present value of net future minimum lease payments $ 5,714

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES We account for income taxes by recognizing deferred tax assets and liabilities based upon temporary differences between the amounts for financial reporting purposes and tax basis of its assets and liabilities. Deferred tax assets decreased by approximately $2.3 million during the nine months ended September 30, 2019 as a result of changes to temporary differences related to non-qualified stock options exercises and change in discount accretion on loans acquired in the PCB acquisition. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In assessing the realization of deferred tax assets, management evaluates both positive and negative evidence, including the forecasts of future income, applicable tax planning strategies, and assessments of current and future economic and business conditions. This analysis is updated quarterly and adjusted as necessary. Based on this analysis, management has determined that a valuation allowance for deferred tax assets was not required at September 30, 2019 . For the three months ended September 30, 2019 and 2018 , income tax expense was $3.3 million and $932 thousand , resulting in an effective income tax rate of 28.9% and 26.4% . For the nine months ended September 30, 2019 and 2018 , income tax expense was $9.7 million and $3.3 million , resulting in an effective income tax rate of 30.8% and 28.3% . Our effective tax rate is lower than the statutory rate of 29.6% during the three months ended September 30, 2019 and higher than the statutory rate during the nine months ended September 30, 2019 due to the tax effect of stock-based compensation. We are subject to federal income and California franchise tax. At September 30, 2019, the federal statute of limitations for the assessment of income tax is closed for all tax years up to and including 2015. The California statute of limitations for the assessment of franchise tax is closed for all years up to and including 2013. We are currently not under examination in any taxing jurisdiction. The total amount of unrecognized tax benefits was $116 thousand and $480 thousand at September 30, 2019 and December 31, 2018, primarily comprised of unrecognized tax benefits from tax positions taken in prior years. The total amount of tax benefits that, if recognized, would favorably impact the effective tax rate was $0 at September 30, 2019 and December 31, 2018. We expect the total amount of unrecognized tax benefits to decrease by $3 thousand within the next twelve months due to the expiration of the statute of limitations for the assessment of taxes. We recognize interest and penalties related to unrecognized tax benefits in income tax expense. We had accrued $18 thousand and $59 thousand of interest at September 30, 2019 and December 31, 2018, respectively. No amounts for penalties were accrued.

Commitments and Contingencies Disclosure [Abstract]
Commitments	COMMITMENTS In the ordinary course of business, we enter into financial commitments to meet the financing needs of our customers. These financial commitments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk not recognized in our condensed consolidated financial statements. Our exposure to loan loss in the event of nonperformance on commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. We use the same credit policies in making commitments as we do for loans reflected in our condensed consolidated financial statements. As of September 30, 2019 and December 31, 2018 , we had the following outstanding financial commitments whose contractual amounts represent credit risk: September 30, December 31, (dollars in thousands) Commitments to extend credit $ 386,974 $ 375,755 Standby letters of credit 8,353 4,019 Commitments to contribute capital to low income housing project partnerships and other CRA investments 2,032 385 Total $ 397,359 $ 380,159 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total amounts do not necessarily represent future cash requirements. We evaluate each client’s credit worthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by us is based on management’s credit evaluation of the customer. The majority of our commitments to extend credit and standby letters of credit are secured by real estate. The reserve for unfunded commitments was $1.4 million at September 30, 2019 and December 31, 2018 . The reserve for unfunded commitments is included in "other liabilities" in our condensed consolidated balance sheets. We committed to invest in a partnership that sponsors affordable housing projects utilizing the Low Income Housing Tax Credit ("LIHTC") pursuant to Section 42 of the Internal Revenue Code. The purpose of this investment is to achieve a satisfactory return on capital, to facilitate the sale of additional affordable housing projects, and to assist in achieving goals associated with the Community Reinvestment Act ("CRA"). Capital contributions are called for up to an amount specified in the partnership agreement. In addition, we invest in other CRA investments such as the Small Business Investment Company ("SBIC") program. At September 30, 2019 , the Company had unfunded commitments to contribute capital to this LIHTC investments and other CRA investments totaling $2.0 million .

Stock-Based Compensation Plans	STOCK-BASED COMPENSATION PLANS Our 2013 Omnibus Stock Incentive Plan (“2013 Plan”) was approved by shareholders in May 2013. Under the terms of the 2013 Plan, officers and key employees may be granted both nonqualified and incentive stock options and directors and other consultants, who are not also an officer or employee, may only be granted nonqualified stock options. The 2013 Plan also permits the grant of stock appreciation rights (“SARs”), restricted shares, deferred shares, performance shares and performance unit awards. The 2013 Plan provides that the total shares of common stock that may be awarded under the plan shall not exceed 1,390,620 shares, of which a maximum of 300,000 shares may be granted as incentive stock options. Stock options, SARs, performance share and unit awards are granted at a price not less than 100% of the fair market value of the stock on the date of grant. Options generally vest over a period of three to five years. The 2013 Plan provides for accelerated vesting if there is a change of control, as defined in the 2013 Plan. Stock options expire no later than ten years from the grant. The 2013 Plan expires in 2023. In connection with the PCB acquisition, we issued replacement stock options exercisable for 420,393 shares of our common stock in cancellation of PCB stock options with an aggregated fair value of $7.4 million to PCB directors, officers and employees, which we refer to as rollover stock options. The remaining term on the rollover stock options ranges from 1 month to 9 years.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Earnings per share (“EPS”) are computed on a basic and diluted basis. Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding. Basic shares outstanding exclude unvested shares of restricted stock and stock options. 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 in the issuance of common stock that shares in our earnings. Our unvested grants of restricted stock contain non-forfeitable rights to dividends, which are required to be treated as participating securities and included in the computation of earnings per share. The following is a reconciliation of net income and shares outstanding used in the computation of basic and diluted EPS: Three Months Ended Nine Months Ended September 30, September 30, June 30, September 30, 2019 2018 Numerator for basic earnings per share: (dollars in thousands, except share and per share data) Net income $ 8,071 $ 6,811 $ 2,604 $ 21,890 $ 8,417 Less: dividends and net income allocated to participating securities (86 ) (76 ) (17 ) (222 ) (73 ) Net income available to common shareholders $ 7,985 $ 6,735 $ 2,587 $ 21,668 $ 8,344 Denominator for basic earnings per share: Basic weighted average common shares outstanding during the period 11,584,955 11,581,889 10,144,954 11,605,687 8,170,234 Denominator for diluted earnings per share: Basic weighted average common shares outstanding during the period 11,584,955 11,581,889 10,144,954 11,605,687 8,170,234 Net effect of dilutive stock options 74,191 93,168 212,115 108,333 98,529 Diluted weighted average common shares 11,659,146 11,675,057 10,357,069 11,714,020 8,268,763 Net income per common share: Basic $ 0.69 $ 0.58 $ 0.26 $ 1.87 $ 1.02 Diluted $ 0.68 $ 0.58 $ 0.25 $ 1.85 $ 1.01

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS The fair value of a financial instrument is the amount at which the asset or obligation could be exchanged (using an exit price notion) in a current transaction between willing parties, other than in a forced or liquidation sale. Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the entire holdings of a particular financial instrument. Because no market value exists for a significant portion of the financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature, involve uncertainties and matters of judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on financial instruments both on and off the balance sheet without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Additionally, tax consequences related to the realization of the unrealized gains and losses can have a potential effect on fair value estimates and have not been considered in many of the estimates. The methods and assumptions used to estimate the fair value of certain financial instruments are described below: Loans. The fair value of loans, which is based on an exit price notion, is generally determined using an income-based approach based on discounted cash flow analysis. This approach utilizes the contractual maturity of the loans and market indications of interest rates, prepayment speeds, defaults and credit risk in determining fair value. For impaired loans, an asset-based approach is applied to determine the estimated fair values of the underlying collateral. This approach utilizes the estimated net sales proceeds to determine the fair value of the loans when deemed appropriate. The implied sales proceeds value provides a better indication of value than using an income-based approach as these loans are not performing or exhibit strong signs indicative of non-performance. Securities. The fair values of securities available-for-sale are determined by matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2). Equity Securities. The fair value of equity securities is based on quoted prices in active markets for identical assets to determine the fair value. If quoted prices are not available to determine fair value, we use other inputs that are directly observable. Recurring fair value measurements The following table provides the hierarchy and fair value for each major category of assets and liabilities measured at fair value on a recurring basis at September 30, 2019 and December 31, 2018 : Recurring Fair Value Measurements Level 1 Level 2 Level 3 Total September 30, 2019: (dollars in thousands) Securities available-for-sale: Mortgage-backed securities $ — $ 7,978 $ — $ 7,978 Collateralized mortgage obligations — 10,306 — 10,306 SBA Pools — 9,060 — 9,060 Securities available-for-sale $ — $ 27,344 $ — $ 27,344 Equity securities: Mutual fund investment $ 2,681 $ — $ — $ 2,681 December 31, 2018: Securities available-for-sale: Mortgage-backed securities $ — $ 8,844 $ — $ 8,844 Collateralized mortgage obligations — 11,461 — 11,461 SBA Pools — 9,238 — 9,238 Securities available-for-sale $ — $ 29,543 $ — $ 29,543 Equity securities: Mutual fund investment $ 2,538 $ — $ — $ 2,538 Nonrecurring fair value measurements These fair value measurements typically result from the application of specific accounting pronouncements under GAAP. The fair value measurements are considered nonrecurring fair value measurements under FASB ASC 820-10. At September 30, 2019 and December 31, 2018 the fair value measurements (Level 3) related to collateral dependent impaired loans totaled $1.9 million and $690 thousand . Total nonrecurring losses (which include charge-offs, net of recoveries and changes in specific reserves) recognized for impaired loans during the three months ended September 30, 2019 and 2018 totaled $624 thousand and $22 thousand in losses. Total nonrecurring losses (which include charge-offs, net of recoveries and changes in specific reserves) recognized for impaired loans during the nine months ended September 30, 2019 and 2018 totaled $624 thousand and $590 thousand in losses. We utilized selling costs ranging from 8% to 10% of appraised values for nonrecurring fair value measurements related to collateral-dependent impaired loans during the three and nine months ended September 30, 2019 and 2018 . There were no transfers of financial assets between Levels 1, 2 and 3 for the three and nine months ended September 30, 2019 and 2018 .

Revenue from Contract with Customer [Abstract]
Revenue Recognition	REVENUE RECOGNITION The portion of our noninterest income which is in scope of Topic 606, Revenue from Contracts with Customers , includes fees from deposit customers for transaction-based fees, account maintenance charges, and overdraft services. Transaction-based fees include items such as ATM and ACH fees, overdraft and stop payment charges, and are recognized at the time such transactions are executed and our service has been fulfilled. Account maintenance charges, which are primarily monthly fees, are earned over the course of the month, which represents the period through which we satisfy our performance obligation. Overdraft fees are recognized at the time the overdraft occurs. Service charges are typically withdrawn from the customer’s account balance. The following is a summary of our noninterest income in-scope and not in-scope of Topic 606: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 (dollars in thousands) Noninterest income, in-scope: Service charges and fees on deposit accounts $ 475 $ 380 $ 1,579 $ 803 Other income 46 58 133 75 Total noninterest income, in-scope 521 438 1,712 878 Noninterest income, not in-scope: Gain on sale of loans 528 171 2,727 866 Net servicing fees 242 39 763 318 Change in fair value of equity securities 14 (23 ) 88 (140 ) Other income 368 87 827 146 Total noninterest income, not in-scope 1,152 274 4,405 1,190 Total noninterest income $ 1,673 $ 712 $ 6,117 $ 2,068

Equity [Abstract]
Equity	EQUITY Dividends During the three months ended September 30, 2019 and 2018 , total quarterly cash dividends declared were $0.20 per share and total cash dividends paid were $2.3 million and $2.3 million . During the nine months ended September 30, 2019 and 2018 , total cash dividends declared were $0.60 per share and total cash dividends paid were $7.0 million and $5.2 million . Stock Repurchase Plan On December 3, 2018, we announced a stock repurchase plan, providing for the repurchase of up to 1.2 million shares, or approximately 10%, of our then outstanding shares (the "repurchase plan"). The repurchase plan permits shares to be repurchased in open market or private transactions, through block trades, and pursuant to any trading plan that may be adopted in accordance with Rules 10b5-1 and 10b-18. The repurchase plan may be suspended, terminated or modified at any time for any reason, including market conditions, the cost of repurchasing shares, the availability of tentative investment opportunities, liquidity, and other factors management deems appropriate. These factors may also affect the timing and amount of share repurchases. The repurchase plan does not obligate us to purchase any particular number of shares. During the three months ended September 30, 2019 , we repurchased 87,500 shares at an average price of $21.84 per share and a total cost of $1.9 million under the repurchase plan. During the nine months ended September 30, 2019 , we repurchased 416,270 shares at an average price of $21.60 per share and total cost of $9.0 million . Since the plan was announced, we have repurchased a total of 452,553 shares at an average price of $21.62 per share. The remaining number of shares authorized to be repurchased under this plan is 747,447 shares at September 30, 2019 .

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS The Company plans to relocate the downtown Los Angeles branch to a smaller space within the same building and has signed a sublease of the current space which shall begin on or after January 1, 2020. The sublease is contingent upon the Company executing a lease for smaller space in the same building and receiving all applicable federal and state regulatory approvals. As a result of this pending move and sublease agreement, the Company expects to recognize an after-tax impairment charge of between $475 thousand and $675 thousand , or $0.04 to $0.06 per diluted share, in the fourth quarter of 2019. Starting in the first quarter of 2020, annualized after-tax cost savings related to the sublease and newly leased space are estimated to be between $250 thousand and $325 thousand , or $0.02 to $0.03 per diluted share, through 2022.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of Bancorp and the Bank and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the instructions to Form 10-Q and Article 10 of Regulation S-X for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments considered necessary for a fair presentation, have been included. Operating results for the nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. These interim period condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements as of and for the years ended December 31, 2018 and 2017 , which are included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (the "SEC"). All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates in the Preparation of Consolidated Financial Statements	Use of Estimates in the Preparation of Consolidated Financial Statements The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change are the determination of the allowance for loan losses, the valuation of acquired loans, the valuation of goodwill and separately identifiable intangible assets associated with mergers and acquisitions, and the valuation of deferred tax assets.
Leases	Leases We determine if an arrangement contains a lease at contract inception and recognize a right-of-use ("ROU") asset and operating lease liability based on the present value of lease payments over the lease term. While our operating leases may include options to extend the term, these options are not included when calculating the ROU asset and lease liability unless we are reasonably certain we will exercise such options. Most of our leases do not provide an implicit rate and, therefore, we determine the present value of lease payments by using our incremental borrowing rate, currently our FHLB secured borrowing rate for the remaining lease term, and other information available at lease commencement. Leases with an initial term of 12 months or less are not recorded in the consolidated balance sheets. Lease expense is recognized on a straight line basis over the lease term. We have lease agreements with lease and non-lease components for which we have elected to account for as a single lease component. Refer to – Accounting Standards Adopted in 2019 below and Note 6. Leases for further discussion on our leasing arrangements and related accounting.
Accounting Standards Adopted in 2019 and Recent Accounting Guidance Not Yet Effective	Accounting Standards Adopted in 2019 We adopted ASU 2016-02, Leases (Topic 842) and ASU 2018-11, Leases (Topic 842): Targeted Improvements, referred to herein as Topic 842, effective January 1, 2019. The new guidance establishes the principles to report transparent and economically neutral information about the assets and liabilities that arise from leases. Entities are required to recognize ROU assets and lease liabilities that arise from leases in the statement of financial position and to disclose qualitative and quantitative information about lease transactions, such as information about variable lease payments and options to renew and terminate leases. Under the amendments in ASU 2018-11, entities may elect not to recast the comparative periods presented when transitioning to the new leasing standard. Upon adoption, we elected to use the modified retrospective transition approach and recorded ROU assets of $6.0 million and lease liabilities of $6.1 million at the date of adoption with no adjustment to opening equity. We elected to apply the package of practical expedients which permits entities to not reassess: (i) whether any expired or existing contracts contain a lease; (ii) lease classification for any expired or existing leases; and (iii) whether initial direct costs for any existing leases qualify for capitalization under the amended guidance. We also elected not to include short-term leases (leases with initial terms of 12 months or less) on the consolidated balance sheets. Recent Accounting Guidance Not Yet Effective In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326) (“ASU 2016-13”), also known as "CECL". This guidance will replace the incurred loss impairment methodology used to estimate the allowance for credit losses in current GAAP with a methodology that reflects future expected credit losses and requires consideration of a broader range of reasonable and supportable forecasts in the credit loss estimates. On October 16, 2019, the FASB decided to delay the effective date of ASU 2016-13 for smaller reporting companies, private companies and other non-SEC filers. We are considered a smaller reporting company. Therefore, this ASU will be effective for the Company on January 1, 2023 with early adoption permitted. Management continues to have a cross functional committee in place to oversee the project, has selected software to implement the new guidance, and has engaged an existing third-party service provider to assist in implementation. We have completed data gap analyses, developed initial modeling assumptions, and run a high level sensitivity analysis. We expect to run parallel calculations, testing, and further sensitivity analysis beginning in the first quarter of 2020. We have not yet determined the potential impact of the adoption of ASU 2016-13 to our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the current goodwill impairment test. Step 2 currently measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, under the amendments in ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. On October 16, 2019, the FASB decided to delay the effective date of ASU 2017-04 for smaller reporting companies, private companies and other non-SEC filers. We are considered a smaller reporting company. Therefore, this ASU will be effective for the Company on January 1, 2023. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We do not expect the adoption of ASU 2017-04 to have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13"). The primary objective of ASU 2018-13 is to improve the effectiveness of disclosures in the notes to financial statements. ASU 2018-13 will be effective on January 1, 2020, although early adoption is permitted. The adoption of ASU 2018-13 is not expected to significantly impact our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) ("ASU 2018-15"). ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). ASU 2018-15 will be effective on January 1, 2020, including interim periods within the years of adoption although early adoption is permitted. ASU 2018-15 is not expected to significantly impact our condensed consolidated financial statements.
