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 primarily commercial and consumer clients in diverse communities and 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 11 full service branches, and 1 lending office located in Los Angeles, Orange and San Diego Counties. Effective May 17, 2019, the Little Tokyo branch will be closed and consolidated with the 6th and Figueroa branch and the San Diego branch operations will be consolidated into our Carlsbad branch. The San Diego location will remain as a loan production office. Effective July 31, 2018, we acquired Pacific Commerce Bancorp (“PCB”) and its wholly-own 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 from August 1, 2018. Refer to Note 2 - Business Combination . 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 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 the Company and its subsidiary and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. 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 quarter ended March 31, 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 months ended March 31, 2018 to conform to the March 31, 2019 presentation. These reclassifications included $96 thousand of stock-based compensation expense for stock options and restricted stock awards for directors that was previously reported in salaries and employee benefits expense and is now included in other expenses. 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 right-of-use ("ROU") assets and operating lease liabilities based on the present value of lease payments over the lease term. While our operating leases may include options to extend the term, we do not take into account the options in 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 7. 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 to not 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 to not include short-term leases (leases with initial terms of twelve 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”). This guidance is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this guidance replace the incurred loss impairment methodology in current US GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable forecasts in the credit loss estimates. In April 2019 the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments . These ASUs will be effective for fiscal years beginning after December 15, 2019, with early adoption available. We plan to adopt the guidance effective January 1, 2020. Management has 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 a data gap analysis and are evaluating assumptions to be used in the sensitivity analysis and parallel runs. We expect to begin parallel calculations, testing, and sensitivity analysis on our initial modeling assumptions and results in the second or third quarter of 2019. We have not yet determined the potential impact to our condensed 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 for interim and annual reporting periods beginning after December 15, 2019, although early adoption is permitted. The adoption of ASU 2018-13 is not expected to significantly impact our condensed 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 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, although early adoption is permitted. ASU 2018-15 is not expected to significantly impact our condensed consolidated financial statements.

Business Combinations [Abstract]
Business Combination	BUSINESS COMBINATION On February 26, 2018, we announced that we entered into an Agreement and Plan of Reorganization and Merger, dated February 23, 2018 (the "merger agreement"), pursuant to which PCB would be merged with and into First Choice Bancorp and PCB’s bank subsidiary, Pacific Commerce Bank, would be merged with and into our bank subsidiary, First Choice Bank (collectively, the “Merger”). Following the receipt of all necessary regulatory and shareholder approvals, we completed the acquisition of PCB on July 31, 2018. The Merger was an all stock transaction valued at approximately $133.3 million , or $13.69 per share, based on the closing price of our common stock of $28.70 at July 31, 2018 . At the effective time of the Merger, each share of PCB common stock was converted into the right to receive 0.47689 shares (referred to as the final exchange ratio) of our common stock, with cash paid in lieu of any fractional shares. The final exchange ratio was higher than the ratio of 0.46531 announced at the time of the acquisition, as the ratio was subject to adjustment resulting from an increase in PCB’s capital due to the exercise of stock options, lower than budgeted merger transaction costs and higher than projected net income during the first six months of 2018. In the aggregate, we issued 4,386,816 shares of our common stock in exchange for the outstanding shares of PCB common stock. In addition, we issued replacement stock options exercisable for 420,393 shares of our common stock in cancellation of PCB stock options with an aggregate fair value of $7.4 million to PCB directors, officers and employees, which we refer to as "rollover options". PCB was headquartered in Los Angeles, California, with $544.7 million in total assets, $414.9 million in gross loans and $474.8 million in total deposits as of July 31, 2018. PCB had six full-service branches in Los Angeles and San Diego Counties. We also maintained the brand name ProAmérica, in Downtown Los Angeles. The acquisition of PCB expanded our footprint in Southern California to the Mexican border. The following table represents the fair value of assets acquired and liabilities assumed of PCB, as of July 31, 2018, recorded using the acquisition method of accounting: Fair Value (in thousands) Assets acquired: Cash and cash equivalents $ 111,035 Loans held for investment, net 399,822 Investment in restricted stock, at cost 4,148 Premises and equipment 719 Servicing assets 1,054 Cash surrender value of bank-owned life insurance 4,712 Deferred taxes 4,612 Core deposit intangible 6,908 Accrued interest receivable and other assets 3,487 Total assets acquired $ 536,497 Liabilities assumed: Deposits $ 474,925 Accrued interest payable and other liabilities 1,724 Total liabilities assumed 476,649 Net assets acquired $ 59,848 Purchase consideration: Fair value of shares of First Choice Bancorp issued in the merger $ 125,902 Fair value of equity awards exchanged 7,371 Total purchase consideration 133,273 Goodwill recognized $ 73,425 As the final PCB tax return has not yet been completed, initial accounting for taxes was incomplete at March 31, 2019 . These fair values are estimates and are subject to adjustment for up to one year after the acquisition date or when additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. These changes could differ materially from what is presented above. Goodwill represents the excess of the purchase consideration over the fair value of the net assets acquired and was primarily attributable to the expected synergies and economies of scale expected from combining PCB's operations with us.

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 March 31, 2019 and December 31, 2018 were as follows: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value March 31, 2019 (in thousands) Securities available-for-sale: Mortgage-backed securities $ 8,944 $ 11 $ (226 ) $ 8,729 Collateralized mortgage obligations 11,355 3 (218 ) 11,140 SBA pools 9,418 — (223 ) 9,195 $ 29,717 $ 14 $ (667 ) $ 29,064 Securities held-to-maturity: U.S. Government and agency securities $ 3,341 $ — $ (61 ) $ 3,280 Mortgage-backed securities 1,970 — (61 ) 1,909 $ 5,311 $ — $ (122 ) $ 5,189 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 March 31, 2019 , by contractual maturities are shown below.

At March 31, 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 sales of any investment securities available-for-sale or held-to-maturity during the three months ended March 31, 2019 and 2018 . There were no maturities or calls of investment securities during the three months ended March 31, 2019 and 2018 . At March 31, 2019 securities held-to-maturity with a carrying amount of $5.3 million were pledged to the Federal Reserve Bank as discussed in Note 9 – Borrowing Arrangements . As of March 31, 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 March 31, 2019 (in thousands) Securities available-for-sale: Mortgage-backed securities $ — $ — $ (226 ) $ 6,940 $ (226 ) $ 6,940 Collateralized mortgage obligations (1 ) 1,113 (217 ) 9,446 (218 ) 10,559 SBA pools — — (223 ) 9,195 (223 ) 9,195 $ (1 ) $ 1,113 $ (666 ) $ 25,581 $ (667 ) $ 26,694 Securities held-to-maturity: U.S. Government and agency securities $ — $ — $ (61 ) $ 3,280 $ (61 ) $ 3,280 Mortgage-backed securities — — (61 ) 1,909 (61 ) 1,909 $ — $ — $ (122 ) $ 5,189 $ (122 ) $ 5,189 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 March 31, 2019 , we had 25 investment securities in an unrealized loss position with total unrealized losses of $789 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, management does not intend to sell and it is not more likely than not that management would be required to sell the securities prior to their anticipated recovery, and the decline in fair value is largely due to changes in interest rates. Equity Securities With A Readily Determinable Fair Value At March 31, 2019 and December 31, 2018 , equity securities with a readily determinable fair value of $2.6 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 in the United States. 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 AOCI to retained earnings for these investments. In addition, we recognized net gains of $35 thousand and net losses of $51 thousand related to changes in fair value during the quarter ended March 31, 2019 and 2018 , all of which related to equity securities held during those periods. 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 March 31, 2019 and December 31, 2018 , the Bank owned $6.1 million of FHLB stock which is carried at cost. During the quarter ended March 31, 2019 , there were no required purchases of FHLB stock. We evaluated the carrying value of our FHLB stock investment at March 31, 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 $6.7 million of FRB stock which is carried at cost at March 31, 2019 and December 31, 2018 . The Bank purchased $12 thousand of FRB stock during the quarter ended March 31, 2019 . We evaluated the carrying value of our FRB stock investment at March 31, 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 March 31, 2019 and December 31, 2018 and are reported in other assets in the condensed consolidated balance sheets. There were no changes in the fair value of these equity securities recognized during the quarter ended March 31, 2019 . During the quarter ended March 31, 2018 , we recognized a $15 thousand loss related to changes in the fair value of these equity securities.

Receivables [Abstract]
Loans	LOANS Our loan portfolio consists primarily of loans to borrowers within our principal market area including 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 lower of 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 March 31, 2019 , we had certain qualifying loans with an unpaid principal balance of $886.1 million pledged as collateral under a secured borrowing arrangement with the FHLB. See Note 9 – Borrowing Arrangements for additional information regarding the FHLB secured line of credit.

At March 31, 2019 net discounts related to acquired loans of $8.7 million was associated with loans acquired in the PCB acquisition and expected to be accreted into interest income over a weighted average life of 5.6 years . At December 31, 2018 net discounts related to acquired loans of $9.5 million was associated with the PCB acquisition.

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. Loss - Loans classified loss are considered uncollectible and of such little value that their continuance as loans is not warranted. The risk category of loans held for investment, net of discounts by class of loans, excluding PCI loans, as of March 31, 2019 and December 31, 2018 was as follows: March 31, 2019 Pass Special Mention Substandard (1) Total (in thousands) Construction and land development $ 185,798 $ — $ — $ 185,798 Real estate: Residential 54,841 — — 54,841 Commercial real estate - owner occupied 182,506 4,065 — 186,571 Commercial real estate - non-owner occupied 381,061 — — 381,061 Commercial and industrial 295,499 5,546 5,568 306,613 SBA loans 150,597 445 4,900 155,942 Consumer 163 — — 163 $ 1,250,465 $ 10,056 $ 10,468 $ 1,270,989 (1) At March 31, 2019 , substandard loans included $1.7 million of impaired loans.

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 $302.0 million and $288.2 million at March 31, 2019 and December 31, 2018 . This includes SBA loans serviced for others of $208.6 million at March 31, 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 , respectively. 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 $93.4 million and $89.8 million at March 31, 2019 and December 31, 2018 for which there is no related servicing assets. 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 risks inherent in SBA servicing assets relates primarily to changes in prepayments that result from shifts 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 March 31, 2019 2018 (in thousands) Balance, beginning of period $ 3,186 $ 2,618 Additions 376 55 Amortization (211 ) (165 ) Balance, end of period $ 3,351 $ 2,508 The fair value of servicing asset for SBA loans is measured at least quarterly and was $3.5 million and $3.3 million as of March 31, 2019 and December 31, 2018 . The significant assumptions used in the valuation of the SBA servicing asset at March 31, 2019 included discount rates, ranging from 8.4% to 29.9% and a weighted average prepayment speed assumption of 15.0% . The following table summarizes the estimated change in the value of servicing assets as of March 31, 2019 given hypothetical shifts in prepayments speeds and yield assumptions: Change in Assumption Change in Estimated Fair Value (in thousands) Prepayment speeds +10% $ (165 ) Prepayment speeds +20% (316 ) Discount rate +1% (98 ) Discount rate +2% (191 ) SBA loans (including SBA 7(a) and SBA 504 loans) sold during the three months ended March 31, 2019 and 2018 totaled $18.6 million and $2.8 million . Total gains on sale of SBA loans were $928 thousand and $247 thousand for the three months ended March 31, 2019 and 2018 . Net servicing fees, a component of noninterest income, represent contractually specified servicing fees reported net of the servicing asset amortization. Net servicing fees totaled $234 thousand and $153 thousand for the three months ended March 31, 2019 and 2018 including contractually specified servicing fees of $445 thousand and $318 thousand , respectively, partially 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, which allowed us to carry forward historical lease classifications, account for lease and nonlease components as a single lease component, and not to recognize a ROU asset and lease liability for short-term leases. Substantially 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 6 months to 4.4 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 did not include renewal options in the measurement of ROU assets and lease liabilities as they are not 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 $220 thousand impairment of the ROU assets and $180 thousand for the estimated impairment of other long lived assets related to the pending consolidation of two branches. The impairment charges are included in occupancy expense with rent expense and other lease costs on the consolidated statements of income. The impairment is based on a discounted cash flow of estimated sublease income over the remaining lease terms. The balance of ROU assets, net of impairment, and lease liabilities are included in other assets and other liabilities on the consolidated balance sheets. During the quarter ended March 31, 2019 , we recognized $53 thousand of variable lease cost primarily representing variable payments such as common area maintenance and utilities and $11 thousand of short-term lease cost. The balances at March 31, 2019 , along with other supplemental information is shown below. ($ in thousands) Balance sheet: Operating lease ROU assets classified as other assets $ 5,338 Operating lease liability classified as other liabilities $ 5,633 Income statement: Operating lease cost classified as occupancy and equipment expense $ 543 Weighted average remaining lease term, in years 3.2 Weighted average discount rate 2.73 % Other Information Cash paid for amounts included in the measurement of lease liabilities $ 560 Maturities of lease liabilities for periods indicated: Twelve months ended March 31, (in thousands) 2020 $ 2,151 2021 1,663 2022 1,279 2023 740 2024 55 Thereafter — Total future minimum lease payments 5,888 Less: Imputed interest (255 ) Present value of net future minimum lease payments $ 5,633

Borrowing Arrangements	BORROWING ARRANGEMENTS Federal Home Loan Bank Secured Line of Credit At March 31, 2019 , the Bank had a secured line of credit of $405.6 million from the FHLB, of which $187.8 million was available. This secured borrowing arrangement is subject to the Bank providing adequate collateral and continued compliance with the Advances and Security Agreement and other eligibility requirements established by the FHLB. At March 31, 2019 , the Bank had pledged as collateral certain qualifying loans with an unpaid principal balance of $886.1 million under this borrowing agreement. Overnight borrowings outstanding under this arrangement were $140.0 million and $90.0 million with a fixed interest rate of 2.60% and 2.56% at March 31, 2019 and December 31, 2018 . The average balance of FHLB borrowings was $35.1 million and $47.4 million with an average interest rate of 2.58% and 1.58% for the quarter ended March 31, 2019 and 2018 . In addition, at March 31, 2019 , the Bank used another $77.8 million of its secured FHLB borrowing capacity by having the FHLB issue (i) letters of credit to meet collateral requirements for deposits from the State of California and other public agencies and (ii) standby letters of credit as credit enhancement to guarantee the performance of customers to third parties. Federal Funds Unsecured Lines of Credit The Bank has established unsecured overnight borrowing arrangements for an aggregate amount of $77.0 million , subject to availability, with five of its primary correspondent banks. In general, interest rates on these lines approximate the federal funds target rate. Overnight borrowings under these credit facilities were $20.0 million and $15.0 million at March 31, 2019 and December 31, 2018 . The average borrowings were $1.1 million and $400 thousand with an average interest rate of 2.70% and 2.37% for the quarter ended March 31, 2019 and 2018 . Federal Reserve Bank Secured Line of Credit At March 31, 2019 , the Bank has a total secured line of credit of $5.0 million with the Federal Reserve Bank. At March 31, 2019 , the Bank had pledged securities held-to-maturity with a carrying value of $5.3 million as collateral for this line. There were no borrowings under this arrangement at or during the quarter ended March 31, 2019 and December 31, 2018 . Senior Secured Notes At March 31, 2019 , the outstanding balance under the holding company's secured line of credit totaled $14.2 million with an interest rate of 5.75% . At December 31, 2018 , the outstanding balance totaled $8.5 million with an interest rate of 5.75% . The average outstanding borrowings under this facility totaled $11.9 million and $13 thousand with an average interest rate of 5.90% and 4.77% for quarter ended March 31, 2019 and 2018 . At March 31, 2019 , we were in compliance with all loan covenants on the facility and the remaining available credit was $10.8 million . One of our executives is also a member of the lending bank's board of directors.

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 our assets and liabilities. 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 March 31, 2019 . For the quarter ended March 31, 2019 and 2018 , income tax expense was $3.3 million and $859 thousand , resulting in an effective income tax rate of 31.7% and 26.5% . Our effective tax rate was unfavorably impacted during the quarter ended March 31, 2019 by the tax effects of stock-based compensation. We are subject to federal income and California franchise tax. At March 31, 2019 , the federal statute of limitations for the assessment of income tax is closed for all tax years up to and including 2014. The California statute of limitations for the assessment of franchise tax is closed for all years up to and including 2013. To our knowledge, we are currently not under examination in any taxing jurisdiction. The total amount of unrecognized tax benefits was $480 thousand at March 31, 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 March 31, 2019 and December 31, 2018 . We expect the total amount of unrecognized tax benefits to decrease by $367 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 for $67 thousand and $59 thousand of interest at March 31, 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 March 31, 2019 and December 31, 2018 , we had the following outstanding financial commitments whose contractual amounts represent credit risk: March 31, December 31, (in thousands) Commitments to extend credit $ 343,291 $ 376,140 Standby letters of credit 4,575 4,019 Total $ 347,866 $ 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 March 31, 2019 and December 31, 2018 . The reserve for unfunded commitments is included in "other liabilities" in our condensed consolidated balance sheets.

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 March 31, 2019 December 31, 2018 March 31, 2018 Numerator for basic earnings per share: (in thousands, except share and per share data) Net income $ 7,008 $ 6,713 $ 2,379 Less: dividends and net income allocated to participating securities (61 ) (50 ) (31 ) Net income available to common shareholders $ 6,947 $ 6,663 $ 2,348 Denominator for basic earnings per share: Basic weighted average common shares outstanding during the period 11,654,450 11,664,557 7,160,938 Denominator for diluted earnings per share: Basic weighted average common shares outstanding during the period 11,654,450 11,664,557 7,160,938 Net effect of dilutive stock options 158,568 215,606 39,119 Diluted weighted average common shares 11,813,018 11,880,163 7,200,057 Net income per common share: Basic $ 0.60 $ 0.57 $ 0.33 Diluted $ 0.59 $ 0.56 $ 0.33

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 Merger, 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. We recognized stock-based compensation expense of $402 thousand and $458 thousand for the three months ended March 31, 2019 and 2018 . A summary of activity in our outstanding stock options during the three months ended March 31, 2019 and 2018 is as follows: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Three Months Ended March 31, 2019: (in thousands) Outstanding, beginning of period 383,212 $ 10.44 Exercised (156,466 ) 10.90 Granted — — Forfeited (386 ) 12.94 Outstanding, end of period 226,360 $ 10.11 3.1 years $ 2,577 Option exercisable 225,278 $ 10.11 3.0 years $ 2,566 Three Months Ended March 31, 2018: Outstanding, beginning of period 65,978 $ 10.17 Exercised — — Granted — — Forfeited — — Outstanding, end of period 65,978 $ 10.17 5.1 years $ 1,008 Option exercisable 56,243 $ 9.97 5.1 years $ 871 As of March 31, 2019 , there was no unrecognized compensation cost related to the outstanding stock options.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

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 not previously presented 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 March 31, 2019 and December 31, 2018 : Recurring Fair Value Measurements Level 1 Level 2 Level 3 Total March 31, 2019: (in thousands) Securities available-for-sale: Mortgage-backed securities $ — $ 8,729 $ — $ 8,729 Collateralized mortgage obligations — 11,140 — 11,140 SBA Pools — 9,195 — 9,195 Securities available-for-sale $ — $ 29,064 $ — $ 29,064 Equity securities: Mutual fund investment $ 2,590 $ — $ — $ 2,590 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 March 31, 2019 and 2018 the fair value measurements (Level 3) related to collateral dependent impaired loans totaled zero and $224 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 March 31, 2019 and 2018 totaled zero and $241 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 months ended March 31, 2019 and 2018 . There were no transfers of financial assets between Levels 1, 2 and 3 for the three months ended March 31, 2019 and 2018 .

Revenue from Contract with Customer [Abstract]
Revenue Recognition	REVENUE RECOGNITION On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , including all subsequent amendments. The adoption of Topic 606 did not have a material impact on our condensed consolidated financial statements because the majority of our revenue is from interest and fees on loans and gain on sales of loans, which are specifically excluded from the scope of Topic 606. The portion of revenue in scope of Topic 606 is included in noninterest income on the condensed consolidated statements of income. The portion of our noninterest income which is in scope of Topic 606 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 March 31, 2019 2018 (in thousands) Noninterest income, in-scope: Service charges and fees on deposit accounts $ 540 $ 215 Other income 42 9 Total noninterest income, in-scope 582 224 Noninterest income, not in-scope: Gain on sale of loans 928 247 Net servicing fees 234 153 Change in fair value of equity securities 35 (66 ) Other income 343 11 Total noninterest income, not in-scope 1,540 345 Total noninterest income $ 2,122 $ 569

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 first quarter of 2019 , we repurchased 315,946 shares at an average price of $21.55 per share under the repurchase plan. Since the plan was announced, we have repurchased a total of 352,229 shares at an average price of $21.57 per share. The remaining number of shares authorized to be repurchased under this plan is 847,771 shares at March 31, 2019 .

Subsequent Events	SUBSEQUENT EVENTS On April 25, 2019 , we declared a $0.20 cash dividend payable on May 23, 2019 to shareholders of record as of May 9, 2019 . We have received all requisite regulatory approvals and have taken steps to consolidate certain branch offices as follows: (i) our Little Tokyo branch, located at 420 East Third Street, Suite 100, Los Angeles, California 90013, will be consolidated with and into our 6th and Figueroa branch, located at 888 W. 6th Street, Suite 200, Los Angeles, California 90017, and (ii) our San Diego branch, located at 12730 High Bluff Drive, Suite 100, San Diego, California 92130, will be consolidated with and into our Carlsbad branch located at 5857 Owens Avenue, Suite 106, Carlsbad, California 92008. In addition, we plan to convert the San Diego branch to a loan center. The events are planned to be effective at the close of business on May 17, 2019. We expect the consolidation of these branches to result in one-time charges of approximately $400 thousand and annualized cost savings of $300 thousand starting in the second quarter of 2019.

Basis of Presentation and Sum_2

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of the Company and its subsidiary and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. 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 quarter ended March 31, 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.
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 to not 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 to not include short-term leases (leases with initial terms of twelve 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”). This guidance is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this guidance replace the incurred loss impairment methodology in current US GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable forecasts in the credit loss estimates. In April 2019 the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments . These ASUs will be effective for fiscal years beginning after December 15, 2019, with early adoption available. We plan to adopt the guidance effective January 1, 2020. Management has 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 a data gap analysis and are evaluating assumptions to be used in the sensitivity analysis and parallel runs. We expect to begin parallel calculations, testing, and sensitivity analysis on our initial modeling assumptions and results in the second or third quarter of 2019. We have not yet determined the potential impact to our condensed 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 for interim and annual reporting periods beginning after December 15, 2019, although early adoption is permitted. The adoption of ASU 2018-13 is not expected to significantly impact our condensed 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 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, although early adoption is permitted. ASU 2018-15 is not expected to significantly impact our condensed consolidated financial statements.
