Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Nature of Operations PCB Bancorp is a bank holding company whose subsidiary is Pacific City Bank. On July 1, 2019, the Company changed its corporate name to “PCB Bancorp” from “Pacific City Financial Corporation.” The Bank is a single operating segment that operates 11 full-service branches in Los Angeles and Orange counties, California, one full-service branch in each of Englewood Cliffs, New Jersey and Bayside, New York, and 10 LPOs in Irvine, Artesia and Los Angeles, California; Annandale, Virginia; Chicago, Illinois; Atlanta, Georgia; Bellevue, Washington; Aurora, Colorado; Carrollton, Texas; and New York, New York. The Bank offers a broad range of loans, deposits, and other products and services predominantly to small and middle market businesses and individuals. Basis of Presentation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary as of December 31, 2019 and 2018 and for the years ended December 31, 2019 , 2018 and 2017 . Significant inter-company accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiaries. The accounting and reporting polices of the Company are based upon GAAP and conform to predominant practices within the financial services industry. Significant accounting policies followed by the Company are presented below. Certain prior period amounts have been reclassified to conform to the current year’s presentation. These reclassifications had no impact on the Company’s consolidated statements of financial condition or operations. Use of Estimates in the Preparation of Financial Statements The preparation of the 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 consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates are subject to change and such change could have a material effect on the consolidated financial statements. Actual results may differ from those estimates. Significant Accounting Policies Cash and Cash Equivalents Cash and cash equivalents include cash on hand, cash items in transit, cash due from the Federal Reserve Bank and other financial institutions, and federal funds sold with original maturities less than 90 days. Banking regulations require that banks maintain a percentage of their deposits as reserves in cash or on deposit with the Federal Reserve Bank. The reserve and clearing requirement balance was $0 at December 31, 2019 and 2018 . Investment Securities Investment securities are classified as held-to-maturity or available-for-sale at the time of purchase based upon the intent of management, liquidity and capital requirements, regulatory limitations and other relevant factors. Debt securities are classified as held-to-maturity when management has the positive intent and ability to hold to maturity. Debt securities are classified as available-for-sale when they might be sold before maturity. Securities held-to-maturity are carried at amortized cost and securities available-for-sale are carried at fair value with unrealized gains and losses, net of taxes, recorded in other comprehensive income. Gains and losses on sales of securities are determined using the specific identification method. Net realized gains or losses on available-for-sale securities are included in noninterest income and, when applicable, are reported as a reclassification adjustment, net of tax, in other comprehensive income. Amortization of premiums and accretion of discounts are included in interest income using the effective interest method. Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: OTTI related to credit loss, which is recognized as a charge against earnings, and OTTI related to other factors, which is recognized in other comprehensive income, net of tax. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. Loans Held-For-Sale The Company originates SBA loans, and certain residential property and commercial property loans with the intention for sale in the secondary market. The Company records the guaranteed portion of SBA loans and these residential property and commercial property loans held-for-sale at the lower of cost or fair value on an aggregate basis. Fair value is based on commitments on hand from investors or prevailing market prices. A valuation allowance is established if the fair value of such loans is lower than their cost, with a corresponding charge to noninterest income. When the Company changes its intent to hold loans for investment, the loans are transferred to held-for-sale at lower of cost or fair value at the time of transfer, as determined on an individual loan level with charges made to allowance for loan losses when the fair value is lower than the cost. Deferred fees and cost on transferred loans are included in the determination of gains or losses on sale of the related loans. Subsequent decreases in fair value, if any, are recognized through a valuation allowance with charges made to noninterest income. If a determination is made that a loan held-for-sale cannot be sold in the foreseeable future, it is transferred to loans held-for-investment at lower of cost or fair value on the transfer date with a charge made to noninterest income when the fair value is lower than the cost. Realized gains and losses from sales of loans included in noninterest income. For sales of guaranteed portion of SBA and certain residential property loans, the loan servicing rights are retained. Loans Held-For-Investment Loans held-for-investment that management has the intent and ability to hold for the foreseeable future are reported at their outstanding unpaid principal balances, net of any charge-offs, deferred fees or costs on originated loans, or unamortized premiums or discounts on purchased loans. Loan origination fees and certain direct origination costs are deferred and recognized in interest income using the effective interest method over the life of the loan. Interest is accrued and credited to income as earned only if deemed collectible. Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. Accrual of interest on loans is discontinued when principal or interest payment is 90 days past due based on the contractual terms of the loan or when, in the opinion of management, there is reasonable doubt as to collectability. When loans are placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Past-due status is based on the contractual terms of the loan. Interest payments that are subsequently received are applied as a reduction to the remaining principal balance as long as concern exists as to the collectability of the principal. Interest accruals are resumed on such loans only when the loans are brought current with respect to interest and principal and when, in the judgment of management, all principal and interest on the loans are expected to be fully collectable. Loan portfolio segments identified by the Company include: real estate (commercial property, residential property, SBA property and construction), commercial and industrial (commercial term, commercial lines of credit, and SBA commercial term), and other consumer loans. Risks associated with the Company’s real estate loans include a decline in the economy and a reduction in real estate values in the Company’s primary markets, an increase in market interest rates, increased competition in pricing and loan structure, and environmental risks. Risks associated with the Company’s commercial and industrial loans include a decline in the economy in the primary markets, an increase in market interest rates, and deterioration of a borrower’s or guarantor’s financial capabilities. Risk associated with the Company’s other consumer loans include the same risks associated with the commercial and industrial loans, but also includes risks related to consumer bankruptcy laws which allow consumers to discharge certain debts. The Company classifies loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, collateral adequacy, credit documentation, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans in regards to credit risk. This analysis typically includes non-homogeneous loans, such as commercial property and commercial and industrial loans, and is performed on an ongoing basis as new information is obtained. The Company uses the following definitions for risk ratings: • Pass - Loans classified as pass include non-homogeneous loans not meeting the risk ratings defined below and smaller, homogeneous loans not assessed on an individual basis. • 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 the deterioration of 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 classified as substandard 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 as substandard, with the added characteristic that the weaknesses make collection or repayment in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Allowance for Loan Losses Allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the loan is uncollectible. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged-off. Amounts are charged-off when available information confirms that specific loans or portions thereof, are uncollectible. Generally, loans are charged off immediately when it is determined that advances to the borrower are in excess of the calculated current fair value of the collateral and if a borrower is deemed incapable of repayment of unsecured debt, there is little or no prospect for near term improvement and no realized strengthening action of significance pending. Other consumer loans are charged off based on delinquency, typically 120 days for closed loans and 180 days for open-end loans, or earlier when it is determined that the loan is uncollectible due to a triggering event, such as bankruptcy, fraud, or death. This methodology for determining charge-offs is consistently applied to each segment. The allowance consists of general reserves (collectively evaluated for impairment) and specific reserves (individually evaluated for impairment). General reserves cover non-impaired loans and are based on historical loss rates over the most recent four years for each portfolio segment, adjusted for the effects of qualitative or environmental factors that are likely to cause estimated credit losses as of the evaluation date to differ from the portfolio segment’s historical loss experience. The Company utilizes a migration analysis to measure actual historical loss experience, with the resulting historical loss rate adjusted for any applicable loss emergence period factors serving as the base loss rate to estimate the amount of appropriate loss reserve. Qualitative factors include consideration of the following: changes in lending policies and procedures; changes in economic conditions; changes in the nature and volume of the portfolio; changes in the experience, ability, and depth of lending management and other relevant staff; changes in the volume and severity of past due, nonaccrual, and other adversely graded loans; changes in the loan review system; changes in the value of the underlying collateral for collateral-dependent loans; concentrations of credit and the effect of other external factors such as competition and legal and regulatory requirements. Specific reserves relate to loans that are individually classified as impaired. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status, collateral value, and the probability of collecting all amounts when due. Measurement of impairment is based on the expected future cash flows of an impaired loan, which are to be discounted at the loan’s effective interest rate, or measured by reference to an observable market value, if one exists, or the fair value of the collateral for a collateral-dependent loan. The Company selects the measurement method on a loan-by-loan basis, with the exception of collateral-dependent loans for which the most viable source of repayment is the continued operation of the collateral or liquidation of the collateral. The impairment for these loans are measured at the fair value of the collateral, less estimated selling cost. If a loan is impaired, the loan is reported, net of the allocated allowance, at the present value of estimated future cash flows using the loan’s effective interest rate or at the fair value of collateral if repayment is expected solely from the collateral. Interest payments received on impaired loans are first applied to principal, then recognized as income based on existing methods to recognize income on nonaccrual loans. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered TDRs and classified as impaired with measurement of impairment as described above. Premises and Equipment Premises and equipment are carried at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives, which ranges from three to seven years for furniture and equipment. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the improvements or the remaining lease term, whichever is shorter. Expenditures for betterments or major repairs are capitalized and those for ordinary repairs and maintenance are charged to operations as part of occupancy and equipment expense as incurred. Federal Home Loan Bank and Other Restricted Stock The Bank is a member of the FHLB and Pacific Coast Bankers’ Bancshares (“PCBB”) system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB and PCBB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on the ultimate recovery of par value. Both cash and stock dividends are reported as income. Other Real Estate Owned OREO represents properties acquired through foreclosure or other proceedings. The Company initially records OREO at fair value at the time of foreclosure. Thereafter, OREO is recorded at the lower of cost or fair value based on their subsequent changes in fair value. The fair value of OREO is generally based on recent real estate appraisals adjusted for estimated selling costs. Any write-down to fair value at the time of transfer to OREO is charged to allowance for loan losses. Property is evaluated regularly to ensure the recorded amount is supported by its current fair value and valuation allowances to reduce the carrying amounts to fair value less estimated costs to dispose are recorded as necessary. Additions to or reductions from valuation allowances are recorded in noninterest expense. Servicing Assets Servicing assets are recognized when servicing rights are retained from the sale of loans, such as sales of guaranteed portion of SBA and certain residential property loans, and are initially recorded at fair value. Fair value is calculated as the present value of estimated future cash flows from the servicing rights based on current market sources, such as the cost to service, discount rates, and prepayment speeds. Servicing assets are amortized into noninterest income over the expected life of the underlying loans. Servicing assets are evaluated for impairment based on the fair value of the servicing rights as compared to the carrying amount. Impairment is determined by stratifying servicing rights into groupings based on predominant risk characteristics, such as collateral type. For purposes of measuring impairment, the Company has identified each servicing asset with the underlying loan being serviced. A valuation allowance is recorded when the fair value is below the carrying amount of the asset. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the valuation allowance may be recorded as an increase to income. The fair values of servicing assets are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and changes in discount rates. Servicing income as reported on the income statement consists of fees earned for servicing loans, net of the amortization of servicing assets and changes in the valuation allowance. The servicing fees are based on a contractual percentage of the outstanding principal and recorded as income when earned. Investment in Qualified Affordable Housing Projects The Company has invested in a limited partnership that operates qualified affordable housing projects for lower income tenants in California. The Company accounts for this investment under the proportional amortization method and the amortization expense is presented as a component of current tax expense. Return of this investment is generated primarily through allocated federal tax credits and other tax benefits. The recorded investment amount was $2.1 million and $2.4 million , respectively, and unfunded commitments were $85 thousand and $831 thousand , respectively, at December 31, 2019 and 2018 . The recorded investment amount is included in Accrued Interest Receivable and Other Assets and unfunded commitment is included in Accrued Interest Payable and Other Liabilities on the Consolidated Statements of Financial Condition. As components of income tax expense, the Company recognized amortizations of $261 thousand , $283 thousand and $219 thousand , respectively, and federal tax credits and other benefits of $304 thousand , $290 thousand and $229 thousand , respectively, for the years ended December 31, 2019 , 2018 and 2017 . The Company determined that there were no events or changes in circumstances indicating that it is more likely than not that the carrying amount of the investment will not be realized. Therefore, no impairment was recorded at December 31, 2019 and 2018 . Earnings Per Share Earnings per share (“EPS”) is computed under the two-class method. Net income allocated to common stock is computed by subtracting income allocated to unvested restricted stock from net income. Income allocated to unvested restricted stock includes cash dividend paid and undistributed income available to holders of unvested restricted stock, if any. Basic EPS is computed by dividing net income allocated to common stock by the weighted-average common shares outstanding excluding the weighted-average unvested restricted stock. Diluted EPS is computed by dividing net income allocated to common stock by the weighted-average common stock outstanding, excluding the weighted-average unvested restricted stock, adjusted for the dilutive effect of the stock options. Diluted EPS reflects the potential dilution that could occur if options or other contracts to issue common stock were exercised or converted into common stock, or resulted in the issuance of common stock that then shared in the earnings of the entity. Transfer of Financial Assets Transfers of financial assets are accounted for sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Share-Based Compensation The Company recognizes the cost of employee services received in exchange for stock options and restricted stock awards (“RSAs”), based on the grant date fair value of those awards. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company's common stock at the date of grant is used for RSAs. This cost is recognized in income over the period which an employee is required to provide services in exchange for the award, generally the vesting period. See Note 12 for additional information on the Company’s stock option plan. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. Interest and penalties related to uncertain tax positions are recorded as part of income tax expense. A valuation allowance is established to reduce the deferred tax asset to the level at which it is more likely than not that the tax benefits will be realized. Realization of tax benefits of deductible temporary differences and carry-forwards depends on having sufficient taxable income of an appropriate character and in the appropriate periods. The Company has adopted FASB ASC 740-10, Income Taxes - Overall that clarifies the accounting for uncertainty in tax positions taken or expected to be taken on a tax return and provides that the tax effects from an uncertain tax position can be recognized in the consolidated financial statements only if, based on its merits, the position is more likely than not to be sustained on audit by taxing authorities. Interest and penalties related to uncertain tax positions are recorded as part of income tax expense. The Company elected to early adopt FASB Accounting Standard Update (“ASU”) 2018-02, Income Statement - Reporting Comprehensive Income as of and for the year ended December 31, 2017, which allows entities to reclassify the stranded tax effects as a result of applying the Tax Cuts and Jobs Act from accumulated other comprehensive income (loss) to retained earnings. As a result of the adoption, the Company recorded a decrease in accumulated other comprehensive income of $242 thousand and an increase in retained earnings for the same amount to eliminate the stranded tax effects at that date from the reduction in the federal statutory tax rate that was enacted in December 22, 2017 and became effective January 1, 2018. Commitments and Contingencies In the ordinary course of business, the Company enters into off-balance sheet financial instruments consisting of commitments to extend credit, commercial letters of credit, and standby letters of credit as described in Note 16. Such financial instruments are recorded in the consolidated financial statements when they are funded or related fees are incurred or received. Fair Value Measurement Fair value is the exchange price that would be received for an asset or paid to transfer a liability (i.e., an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Current accounting guidance establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs when measuring fair value. The guidance describes three levels of inputs that may be used to measure fair value: • Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2: Significant observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. See Note 2 for more information and disclosures relating to the Company’s fair value measurements. Adopted Accounting Pronouncements During the year ended December 31, 2019 , the following accounting pronouncements applicable to the Company were adopted: In February 2016, the FASB issued Accounting Standard Update (“ASU”) 2016-02, “Leases (Topic 842).” In July 2018, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842, Leases,” and ASU 2018-11, “Leases Topic 842, Targeted Improvements,” to provide additional clarification, implementation, and transition guidance on certain aspects of ASU 2016-02. The amendments in ASU 2016-02 require lessees to recognize lease assets and lease liabilities for both leases classified as operating leases and finance leases, except leases with a term of 12 months or less where lessees are permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. For leases with a term of greater than 12 months, lessees are required to recognize a liability to make lease payments and a right-of-use assets representing its right to use the underlying asset for the lease term measured at the present value of the lease payments. ASU 2016-02 and ASU 2018-10 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for a public business entity. Under ASU 2018-11, an additional transition option was provided that would allow entities to not apply the new guidance in the comparative periods they present in their financial statements in the year of adoption. Under this optional transition method, entities will be allowed to continue using and presenting leases under Accounting Standard Codification (“ASC”) 840 for prior years’ comparative periods and then prospectively adopt ASC 842 on January 1, 2019, recognizing a cumulative-effect adjustment to the opening balance of retained earnings. The Company adopted this guidance in the first quarter of 2019 using the optional transition method with a cumulative effect adjustment to retained earnings without restating prior period financial statements for comparable amounts. The Company elected the package of practical expedients permitted under the transition guidance within this ASU, which allowed the Company to carry forward the historical lease classification. The Company completed its review of its existing lease contracts and service contracts that may include embedded leases, and updated processes and internal controls for leasing activities. The Company recognized right-of-use lease assets and liabilities of $9.6 million and $10.6 million , respectively, with a cumulative effect adjustment of $53 thousand to retained earnings at the date of adoption. Adoption of this ASU did not have a material impact on the Company’s consolidated financial statements other than the recognition of right-of-use lease assets and liabilities. See Note 6 for additional information. In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” The amendments in this ASU shorten the amortization period for certain callable debt securities acquired at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount, which continue to be amortized to maturity. Public business entities must prospectively apply the amendments in this ASU to annual periods beginning after December 15, 2018, including interim periods. Adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted The following are recently issued accounting pronouncements applicable to the Company that have not yet been adopted: In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326).” The amendments in this ASU require that entities change the impairment model for most financial assets that are measured at amortized cost and certain other instruments from an incurred loss model to an expected loss model. Under this model, entities will estimate credit losses over the entire contractual term of the instrument from the date of initial recognition of that instrument. It includes financial assets such as loan receivables, held-to-maturity debt securities, net investment in leases that are not accounted for at fair value through net income, and certain off-balance sheet credit exposures. This ASU is effective for public business entities that are SEC filers for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In 2019, the FASB amended this ASU, which delays the effective date to 2023 for certain SEC filers that are Smaller Reporting Companies, which would apply to the Company. The Company plans to adopt this ASU at the delayed effective date of 2023.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value including a three-level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (i.e. an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The three-level fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value are defined as follows: • Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2: Significant observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Fair value is measured on a recurring basis for certain assets and liabilities in which fair value is the primary basis of accounting. Additionally, fair value is used on a non-recurring basis to evaluate certain assets or liabilities for impairment or for disclosure purposes. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company records securities available-for-sale at fair value on a recurring basis. Certain other assets, such as loans held-for-sale, impaired loans, servicing assets and OREO are recorded at fair value on a non-recurring basis. Non-recurring fair value measurements typically involve assets that are periodically evaluated for impairment and for which any impairment is recorded in the period in which the re-measurement is performed. The following is a description of valuation methodologies used for assets and liabilities recorded at fair value: Investment securities : The fair values of securities available-for-sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1) or 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). Management reviews the valuation techniques and assumptions used by the provider and determines that the provider uses widely accepted valuation techniques based on observable market inputs appropriate for the type of security being measured. Securities held-to-maturity are not measured at fair value on a recurring basis. Loans held-for-sale : The Company records SBA loans held-for-sale, residential property loans held-for-sale and certain non-residential real estate loans held-for-sale at the lower of cost or fair value, on an aggregate basis. The Company obtains fair values from a third party independent valuation service provider. Loans held-for-sale accounted for at the lower of cost or fair value are considered to be recognized at fair value when they are recorded at below cost, on an aggregate basis, and are classified as Level 2. Impaired loans : The Company records fair value adjustments on certain loans that reflect (i) partial write-downs, through charge-offs or specific reserve allowances, that are based on the current appraised or market-quoted value of the underlying collateral or (ii) the full charge-off of the loan carrying value. In some cases, the properties for which market quotes or appraised values have been obtained are located in areas where comparable sales data is limited, outdated, or unavailable. Fair value estimates for collateral-dependent impaired loans are obtained from real estate brokers or other third-party consultants, and are classified as Level 3. Other real estate owned : The Company initially records OREO at fair value at the time of foreclosure. Thereafter, OREO is recorded at the lower of cost or fair value based on their subsequent changes in fair value. The fair value of OREO is generally based on recent real estate appraisals adjusted for estimated selling costs. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments may be significant and result in a Level 3 classification due to the unobservable inputs used for determining fair value. Only OREO with a valuation allowance are considered to be carried at fair value. Servicing Assets: Servicing assets represent the value of servicing rights associated with servicing loans that have been sold. The fair value for servicing assets is determined through discounted cash flow analysis and utilizes discount rates and prepayment speed assumptions as inputs. All of these assumptions require a significant degree of management estimation and judgment. The fair market valuation is performed on a quarterly basis for servicing assets. Servicing assets are accounted for at the lower of cost or market value and considered to be recognized at fair value when they are recorded at below cost and are classified as Level 3.

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 consolidated 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 following methods and assumptions were used to estimate the fair value of significant financial instruments. Financial assets : The carrying amounts of interest-bearing deposits with other financial institutions and accrued interest receivable are considered to approximate fair value. The fair values of investment securities are generally based on matrix pricing (Level 2). The fair value of loans is estimated based on a discounted cash flow approach under an exit price notion. The fair value reflects the estimated yield that would be negotiated with a willing market participant. Because sale transactions of such loans are not readily observable, as many of the loans have unique risk characteristics, the valuation is based on significant unobservable inputs (Level 3). It is not practical to determine the fair value of FHLB and other restricted stock due to restrictions placed on its transferability. Financial liabilities : The carrying amounts of accrued interest payable are considered to approximate fair value. The fair value of deposits is estimated based on discounted cash flows. The discount rate is derived from the interest rates currently being offered for similar remaining maturities. Non-maturity deposits are estimated based on their historical decaying experiences (Level 3). The fair value of FHLB advances is estimated based on discounted cash flows. The discount rate is derived from the current market rates for borrowings with similar remaining maturities (Level 2). Off-balance-sheet financial instruments : The fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements. The fair value of these financial instruments is not material and is excluded from the table below. The following table presents the carrying value and estimated fair values of financial assets and liabilities as of the dates indicated: Carrying Value Fair Value Fair Value Measurements ($ in thousands) Level 1 Level 2 Level 3 December 31, 2019 Financial assets: Interest-bearing deposits in other financial institutions $ 128,420 $ 128,420 $ 128,420 $ — $ — Securities available-for-sale 97,566 97,566 — 97,566 — Securities held-to-maturity 20,154 20,480 — 20,480 — Loans held-for-sale 1,975 2,102 — 2,102 — Net loans held-for-investment 1,436,451 1,449,383 — — 1,449,383 FHLB and other restricted stock 8,345 N/A N/A N/A N/A Accrued interest receivable 5,136 5,136 78 375 4,683 Financial liabilities: Deposits $ 1,479,307 $ 1,468,540 $ — $ — $ 1,468,540 FHLB advances 20,000 20,092 — 20,092 — Accrued interest payable 6,004 6,004 — 1 6,003 December 31, 2018 Financial assets: Interest-bearing deposits in other financial institutions $ 138,152 $ 138,152 $ 138,152 $ — $ — Securities available-for-sale 146,991 146,991 — 146,991 — Securities held-to-maturity 21,760 21,152 — 21,152 — Loans held-for-sale 5,781 — — 6,175 — Net loans held-for-investment 1,325,515 1,337,299 — — 1,337,299 FHLB and other restricted stock 7,433 N/A N/A N/A N/A Accrued interest receivable 5,178 5,178 112 568 4,498 Financial liabilities: Deposits $ 1,443,753 $ 1,425,023 $ — $ — $ 1,425,023 FHLB advances 30,000 29,641 — 29,641 — Accrued interest payable 6,223 6,223 — 1 6,222

OTTI is recognized when fair value is below the amortized cost where: (i) an entity has the intent to sell the security; (ii) it is more likely than not that an entity will be required to sell the security before recovery of its amortized cost basis; or (iii) an entity does not expect to recover the entire amortized cost basis of the security. All individual securities in a continuous unrealized loss position for 12 months or more as of December 31, 2019 and 2018 had an investment grade rating upon purchase. The issuers of these securities have not established any cause for default on these securities and various rating agencies have reaffirmed their long-term investment grade status as of December 31, 2019 and 2018 . These securities have fluctuated in value since their purchase dates as market interest rates fluctuated. The Company does not intend to sell these securities and it is more likely than not that the Company will not be required to sell before the recovery of its amortized cost basis. The Company determined that the investment securities with unrealized losses for twelve months or more are not other-than-temporary impaired, and, therefore, no impairment was recognized during the years ended December 31, 2019 , 2018 and 2017 .

As a result of the Tax Cuts and Jobs Act, the Company revalued its deferred tax assets and liabilities and recorded a reduction of its net deferred tax assets in the amount of $25 thousand and $1.6 million in deferred income tax expense for the years ended December 31, 2018 and 2017, respectively. The Tax Cuts and Jobs Act also places limits on certain tax deductions beginning in 2018. The following table presents the components of the net deferred tax assets recognized in the accompanying consolidated balance sheets as of the dates indicated: December 31, ($ in thousands) 2019 2018 Deferred tax assets: Allowance for loan losses $ 4,219 $ 3,866 Share-based compensation 299 264 Unrealized loss on investment securities 84 744 Loans held-for-sale market adjustment 99 — Operating lease liabilities 2,931 — Deferred rent payable — 181 State tax benefit 947 739 Other 312 348 Total deferred tax assets 8,891 6,142 Deferred tax liabilities: Depreciation on premises and equipment 308 453 Loans held-for-sale market adjustment — 1,653 Deferred loan origination costs 597 582 Operating lease assets 2,638 — Other 60 77 Total deferred tax liabilities 3,603 2,765 Deferred tax assets, net $ 5,288 $ 3,377 The Company adopted ASU 2016-02 “Leases (Topic 842)” on January 1, 2019, but this new standard did not change the treatment of leases for income tax purposes. The right-of-use assets and related leases liabilities are not required to be capitalized for income tax purposes, and this difference between the GAAP and income tax basis resulted in temporary differences. Accordingly, the Company recognized deferred tax assets and liabilities associated with right-of-use assets and related leases liabilities for the year ended December 31, 2019 . The Company had no valuation allowances for deferred tax assets as of December 31, 2019 and 2018 . Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences, and a valuation allowance was not necessary as of December 31, 2019 and 2018 . At December 31, 2019 and 2018 , the Company had no unrecognized tax benefits, or related accrued interest or penalties. In the event the Company is assessed interest and/or penalties by federal or state tax authorities, such amounts will be classified in the consolidated financial statements as income tax expense. The Company and its subsidiaries are subject to U.S. federal and various state jurisdictions income tax examinations. As of December 31, 2019 , the Company is no longer subject to examination by taxing authorities for tax years before 2016 for federal taxes and before 2015 for various state jurisdictions. The statute of limitations vary by state, and state taxes other than California have been minimal and immaterial to the Company’s financial results.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the ordinary course of business, the Company enters into financial commitments to meet the financing needs of its customers. These financial commitments include commitments to extend credit and letters of credit. Those instruments involve to varying degrees, elements of credit, and interest rate risk not recognized in the Company’s consolidated financial statements. The following table presents outstanding financial commitments whose contractual amount represents credit risk as of the dates indicated: December 31, ($ in thousands) 2019 2018 Commitments to extend credit $ 171,608 $ 127,443 Standby letters of credit 3,300 2,998 Commercial letters of credit 292 477 Total $ 175,200 $ 130,918 The Company’s 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. The Company uses the same credit policies in making commitments as it does for the loans reflected in the consolidated financial statements. The Company maintained reserve for off-balance sheet items of $301 thousand and $139 thousand , respectively, at December 31, 2019 and 2018 . 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. The Company evaluates each client’s credit worthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Company is based on management’s credit evaluation of the customer. Litigation The Company is involved in various matters of litigation, which have arisen in the ordinary course of business. In the opinion of management, the disposition of pending matters of litigation will not have a material effect on the Company’s consolidated financial statements.

Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters Under the Basel III rules, the Bank must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer was fully phased in from 0.0% in 2015 to 2.50% by 2019. Management believes as of December 31, 2019 and 2018 , the Bank met all capital adequacy requirements to which they are subject to. Based on changes to the Federal Reserve’s definition of a “Small Bank Holding Company” in 2018, which increased the threshold to $3 billion in assets, the Company is not currently subject to separate minimum capital measurements. At such time as the Company reaches the $3 billion asset level, it will again be subject to capital measurements independent of the Bank. For comparison purposes, the Company’s ratios are included in following discussion as well, all of which would have exceeded the “well-capitalized” level had the Company been subject to separate capital minimums. The Company and the Bank’s capital conservation buffer was 8.90% and 8.71% , respectively, as of December 31, 2019 , and 9.31% and 9.21% , respectively, as of December 31, 2018 . Unrealized gain or loss on securities available-for-sale is not included in computing regulatory capital.

As a California corporation, the Company is subject to the limitations of California law, which allows a corporation to distribute cash or property to shareholders, including a dividend or repurchase or redemption of shares, if the corporation meets either a retained earnings test or a “balance sheet” test. Under the retained earnings test, the Company may make a distribution from retained earnings to the extent that its retained earnings exceed the sum of (a) the amount of the distribution plus (b) the amount, if any, of dividends in arrears on shares with preferential dividend rights. The Company may also make a distribution if, immediately after the distribution, the value of its assets equals or exceeds the sum of (a) its total liabilities plus (b) the liquidation preference of any shares which have a preference upon dissolution over the rights of shareholders receiving the distribution. Indebtedness is not considered a liability if the terms of such indebtedness provide that payment of principal and interest thereon are to be made only if, and to the extent that, a distribution to shareholders could be made under the balance sheet test. The Federal Reserve, the FDIC and CDBO periodically examine the Company’s business, including compliance with laws and regulations. If, as a result of an examination, a banking agency were to determine that the Company’s financial condition, capital resources, asset quality, earnings prospects, management, liquidity or other aspects of any of the Company’s operations had become unsatisfactory, or that the Company was in violation of any law or regulation, they may take a number of different remedial actions as they deem appropriate. These actions include the power to enjoin “unsafe or unsound” practices, to require affirmative action to correct any conditions resulting from any violation or practice, to issue an administrative order that can be judicially enforced, to direct an increase in Company’s capital, to restrict growth, to assess civil money penalties, to fine or remove officers and directors and, if it is concluded that such conditions cannot be corrected or there is an imminent risk of loss to depositors, to terminate the Company’s deposit insurance and place the Company into receivership or conservatorship. On April 30, 2019, the FDIC, the CDBO and the Bank entered into a stipulation consenting to the issuance of a consent order (the “Order”) relating to the Bank’s BSA/AML. The Order requires, among other things, that the Bank correct all violations found in the prior examination and to improve its process to better identify and monitor accounts and transactions that pose a greater than normal risk for compliance with BSA/AML. The Order also requires the Board of Directors of the Bank to increase its oversight of the Bank’s compliance with BSA/AML rules and regulations. In addition, the Bank is to ensure that the BSA/AML compliance program is managed by a qualified officer with sufficient experience and resources necessary to administer an effective BSA/AML compliance program, and to seek prior FDIC and CDBO non-objection to a change in such officer or the officer in charge of Office of Foreign Assets Control compliance matters, or material changes to their responsibilities. Further, the Order requires that the Bank develop and maintain an effective BSA/AML compliance program, monitoring mechanisms, validation of risk rating and suspicious activity monitoring, and training programs for staff. Further, the Bank must review and enhance its BSA/AML risk assessment and customer due diligence, complete a BSA/AML staffing assessment and conduct a “look back” to more highly scrutinize certain transactions that occurred during a six-month period in 2018 to determine if any suspicious activity requiring reporting went undetected. Finally, the Bank must provide periodic reports of progress to the FDIC and CDBO and provide for independent testing of the overall compliance program to ensure continued compliance, and seek prior FDIC and CDBO non-objection to the establishment of any new branches or other offices, or introduction of new delivery channels, products, services, or lines of business. Subsequent to the Order, the Bank implemented many actions to respond to the requirements of the Order and submitted all required reports to the FDIC and CDBO. Recently, the FDIC and CDBO have raised concerns with the depth of the “look back” and continued turnover in the Bank's BSA department, and management is reviewing both concerns in detail and intends to address them. Even though the Company believes that the Bank has addressed many of items under the Order, it will take some time to address, to the satisfaction of the regulators, the specific issues unique to the Bank’s operation and it is still uncertain whether acceptable progress towards compliance with the Order, as determined in the sole discretion of the FDIC and CDBO, will ultimately be achieved in the future.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition On January 1, 2018, the Company adopted ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” and all subsequent ASUs that are related to Topic 606. The implementation of the new standard did not have a material impact on the measurement, timing, or recognition of revenue. Accordingly, no cumulative effect adjustment to opening retained earnings was deemed necessary. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts were not adjusted and continue to be reported in accordance with the historic accounting under Topic 605. Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as gain or loss associated with mortgage servicing assets and financial guarantees are also not within the scope of the new guidance. Topic 606 is applicable to noninterest income such as deposit related fees, interchange fees, and merchant related income. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Noninterest income considered to be within the scope of Topic 606 is discussed below. Service charges and fees on deposits : Deposit account service charges consist of monthly service fees, account analysis fees, non-sufficient funds (“NSF”) charges and other deposit related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. NSF charges, and other deposit account service charges are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time as incurred. Debit card fees : When customers use their debit cards to pay merchants for goods or services, the Company retains a fee from the funds collected from the related deposit account and transfers the remaining funds to the payment network for remittance to the merchant. The performance obligation to the merchant is satisfied and the fee is recognized at the point in time when the funds are collected and transferred to the payment network. Gain (loss) on sale of other real estate owned : The Company’s performance obligation for sale of OREO is the transfer of title and ownership rights of the OREO to the buyer, which occurs at the settlement date when the sale proceeds are received and income is recognized. Wire transfer fees and other service charges : Wire transfer fees and other service charges are transaction based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time as incurred. The following table presents revenue from contracts with customers within the scope of ASC 606 for the periods indicated: Year Ended December 31, ($ in thousands) 2019 2018 2017 Noninterest income in-scope of Topic 606 Service charges and fees on deposits: Monthly service fees $ 113 $ 108 $ 100 Account analysis fees 972 975 912 Non-sufficient funds charges 364 326 276 Other deposit related fees 95 91 89 Total service charges and fees on deposits 1,544 1,500 1,377 Debit card fees 272 221 203 Gain (loss) on sale of other real estate owned (1 ) 3 (20 ) Wire transfer fees 515 472 431 Other service charges 221 243 208 Total noninterest income in-scope of Topic 606 $ 2,551 $ 2,439 $ 2,199

Basis of Presentation and Sig_2

Basis of Presentation and Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary as of December 31, 2019 and 2018 and for the years ended December 31, 2019 , 2018 and 2017 . Significant inter-company accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiaries.
Basis of Presentation	The accounting and reporting polices of the Company are based upon GAAP and conform to predominant practices within the financial services industry. Significant accounting policies followed by the Company are presented below. Certain prior period amounts have been reclassified to conform to the current year’s presentation. These reclassifications had no impact on the Company’s consolidated statements of financial condition or operations.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of the 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 consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates are subject to change and such change could have a material effect on the consolidated financial statements. Actual results may differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand, cash items in transit, cash due from the Federal Reserve Bank and other financial institutions, and federal funds sold with original maturities less than 90 days. Banking regulations require that banks maintain a percentage of their deposits as reserves in cash or on deposit with the Federal Reserve Bank.
Investment Securities	Investment Securities Investment securities are classified as held-to-maturity or available-for-sale at the time of purchase based upon the intent of management, liquidity and capital requirements, regulatory limitations and other relevant factors. Debt securities are classified as held-to-maturity when management has the positive intent and ability to hold to maturity. Debt securities are classified as available-for-sale when they might be sold before maturity. Securities held-to-maturity are carried at amortized cost and securities available-for-sale are carried at fair value with unrealized gains and losses, net of taxes, recorded in other comprehensive income. Gains and losses on sales of securities are determined using the specific identification method. Net realized gains or losses on available-for-sale securities are included in noninterest income and, when applicable, are reported as a reclassification adjustment, net of tax, in other comprehensive income. Amortization of premiums and accretion of discounts are included in interest income using the effective interest method. Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: OTTI related to credit loss, which is recognized as a charge against earnings, and OTTI related to other factors, which is recognized in other comprehensive income, net of tax. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis.
Loans Held-For-Sale	Loans Held-For-Sale The Company originates SBA loans, and certain residential property and commercial property loans with the intention for sale in the secondary market. The Company records the guaranteed portion of SBA loans and these residential property and commercial property loans held-for-sale at the lower of cost or fair value on an aggregate basis. Fair value is based on commitments on hand from investors or prevailing market prices. A valuation allowance is established if the fair value of such loans is lower than their cost, with a corresponding charge to noninterest income. When the Company changes its intent to hold loans for investment, the loans are transferred to held-for-sale at lower of cost or fair value at the time of transfer, as determined on an individual loan level with charges made to allowance for loan losses when the fair value is lower than the cost. Deferred fees and cost on transferred loans are included in the determination of gains or losses on sale of the related loans. Subsequent decreases in fair value, if any, are recognized through a valuation allowance with charges made to noninterest income. If a determination is made that a loan held-for-sale cannot be sold in the foreseeable future, it is transferred to loans held-for-investment at lower of cost or fair value on the transfer date with a charge made to noninterest income when the fair value is lower than the cost. Realized gains and losses from sales of loans included in noninterest income. For sales of guaranteed portion of SBA and certain residential property loans, the loan servicing rights are retained.
Loans Held-For-Investment	Loans Held-For-Investment Loans held-for-investment that management has the intent and ability to hold for the foreseeable future are reported at their outstanding unpaid principal balances, net of any charge-offs, deferred fees or costs on originated loans, or unamortized premiums or discounts on purchased loans. Loan origination fees and certain direct origination costs are deferred and recognized in interest income using the effective interest method over the life of the loan. Interest is accrued and credited to income as earned only if deemed collectible. Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. Accrual of interest on loans is discontinued when principal or interest payment is 90 days past due based on the contractual terms of the loan or when, in the opinion of management, there is reasonable doubt as to collectability. When loans are placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Past-due status is based on the contractual terms of the loan. Interest payments that are subsequently received are applied as a reduction to the remaining principal balance as long as concern exists as to the collectability of the principal. Interest accruals are resumed on such loans only when the loans are brought current with respect to interest and principal and when, in the judgment of management, all principal and interest on the loans are expected to be fully collectable. Loan portfolio segments identified by the Company include: real estate (commercial property, residential property, SBA property and construction), commercial and industrial (commercial term, commercial lines of credit, and SBA commercial term), and other consumer loans. Risks associated with the Company’s real estate loans include a decline in the economy and a reduction in real estate values in the Company’s primary markets, an increase in market interest rates, increased competition in pricing and loan structure, and environmental risks. Risks associated with the Company’s commercial and industrial loans include a decline in the economy in the primary markets, an increase in market interest rates, and deterioration of a borrower’s or guarantor’s financial capabilities. Risk associated with the Company’s other consumer loans include the same risks associated with the commercial and industrial loans, but also includes risks related to consumer bankruptcy laws which allow consumers to discharge certain debts. The Company classifies loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, collateral adequacy, credit documentation, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans in regards to credit risk. This analysis typically includes non-homogeneous loans, such as commercial property and commercial and industrial loans, and is performed on an ongoing basis as new information is obtained. The Company uses the following definitions for risk ratings: • Pass - Loans classified as pass include non-homogeneous loans not meeting the risk ratings defined below and smaller, homogeneous loans not assessed on an individual basis. • 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 the deterioration of 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 classified as substandard 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 as substandard, with the added characteristic that the weaknesses make collection or repayment in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.
Allowance for Loan Losses	Allowance for Loan Losses Allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the loan is uncollectible. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged-off. Amounts are charged-off when available information confirms that specific loans or portions thereof, are uncollectible. Generally, loans are charged off immediately when it is determined that advances to the borrower are in excess of the calculated current fair value of the collateral and if a borrower is deemed incapable of repayment of unsecured debt, there is little or no prospect for near term improvement and no realized strengthening action of significance pending. Other consumer loans are charged off based on delinquency, typically 120 days for closed loans and 180 days for open-end loans, or earlier when it is determined that the loan is uncollectible due to a triggering event, such as bankruptcy, fraud, or death. This methodology for determining charge-offs is consistently applied to each segment. The allowance consists of general reserves (collectively evaluated for impairment) and specific reserves (individually evaluated for impairment). General reserves cover non-impaired loans and are based on historical loss rates over the most recent four years for each portfolio segment, adjusted for the effects of qualitative or environmental factors that are likely to cause estimated credit losses as of the evaluation date to differ from the portfolio segment’s historical loss experience. The Company utilizes a migration analysis to measure actual historical loss experience, with the resulting historical loss rate adjusted for any applicable loss emergence period factors serving as the base loss rate to estimate the amount of appropriate loss reserve. Qualitative factors include consideration of the following: changes in lending policies and procedures; changes in economic conditions; changes in the nature and volume of the portfolio; changes in the experience, ability, and depth of lending management and other relevant staff; changes in the volume and severity of past due, nonaccrual, and other adversely graded loans; changes in the loan review system; changes in the value of the underlying collateral for collateral-dependent loans; concentrations of credit and the effect of other external factors such as competition and legal and regulatory requirements. Specific reserves relate to loans that are individually classified as impaired. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status, collateral value, and the probability of collecting all amounts when due. Measurement of impairment is based on the expected future cash flows of an impaired loan, which are to be discounted at the loan’s effective interest rate, or measured by reference to an observable market value, if one exists, or the fair value of the collateral for a collateral-dependent loan. The Company selects the measurement method on a loan-by-loan basis, with the exception of collateral-dependent loans for which the most viable source of repayment is the continued operation of the collateral or liquidation of the collateral. The impairment for these loans are measured at the fair value of the collateral, less estimated selling cost. If a loan is impaired, the loan is reported, net of the allocated allowance, at the present value of estimated future cash flows using the loan’s effective interest rate or at the fair value of collateral if repayment is expected solely from the collateral. Interest payments received on impaired loans are first applied to principal, then recognized as income based on existing methods to recognize income on nonaccrual loans. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered TDRs and classified as impaired with measurement of impairment as described above.
Premises and Equipment	Premises and Equipment Premises and equipment are carried at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives, which ranges from three to seven years for furniture and equipment. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the improvements or the remaining lease term, whichever is shorter. Expenditures for betterments or major repairs are capitalized and those for ordinary repairs and maintenance are charged to operations as part of occupancy and equipment expense as incurred.
Federal Home Loan Bank and Other Restricted Stock	Federal Home Loan Bank and Other Restricted Stock The Bank is a member of the FHLB and Pacific Coast Bankers’ Bancshares (“PCBB”) system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB and PCBB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on the ultimate recovery of par value. Both cash and stock dividends are reported as income.
Other Real Estate Owned	Other Real Estate Owned OREO represents properties acquired through foreclosure or other proceedings. The Company initially records OREO at fair value at the time of foreclosure. Thereafter, OREO is recorded at the lower of cost or fair value based on their subsequent changes in fair value. The fair value of OREO is generally based on recent real estate appraisals adjusted for estimated selling costs. Any write-down to fair value at the time of transfer to OREO is charged to allowance for loan losses. Property is evaluated regularly to ensure the recorded amount is supported by its current fair value and valuation allowances to reduce the carrying amounts to fair value less estimated costs to dispose are recorded as necessary. Additions to or reductions from valuation allowances are recorded in noninterest expense.
Servicing Assets	Servicing Assets Servicing assets are recognized when servicing rights are retained from the sale of loans, such as sales of guaranteed portion of SBA and certain residential property loans, and are initially recorded at fair value. Fair value is calculated as the present value of estimated future cash flows from the servicing rights based on current market sources, such as the cost to service, discount rates, and prepayment speeds. Servicing assets are amortized into noninterest income over the expected life of the underlying loans. Servicing assets are evaluated for impairment based on the fair value of the servicing rights as compared to the carrying amount. Impairment is determined by stratifying servicing rights into groupings based on predominant risk characteristics, such as collateral type. For purposes of measuring impairment, the Company has identified each servicing asset with the underlying loan being serviced. A valuation allowance is recorded when the fair value is below the carrying amount of the asset. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the valuation allowance may be recorded as an increase to income. The fair values of servicing assets are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and changes in discount rates. Servicing income as reported on the income statement consists of fees earned for servicing loans, net of the amortization of servicing assets and changes in the valuation allowance. The servicing fees are based on a contractual percentage of the outstanding principal and recorded as income when earned.
Investments in Qualified Affordable Housing Projects	Investment in Qualified Affordable Housing Projects The Company has invested in a limited partnership that operates qualified affordable housing projects for lower income tenants in California. The Company accounts for this investment under the proportional amortization method and the amortization expense is presented as a component of current tax expense. Return of this investment is generated primarily through allocated federal tax credits and other tax benefits.
Earnings Per Share	Earnings Per Share Earnings per share (“EPS”) is computed under the two-class method. Net income allocated to common stock is computed by subtracting income allocated to unvested restricted stock from net income. Income allocated to unvested restricted stock includes cash dividend paid and undistributed income available to holders of unvested restricted stock, if any. Basic EPS is computed by dividing net income allocated to common stock by the weighted-average common shares outstanding excluding the weighted-average unvested restricted stock. Diluted EPS is computed by dividing net income allocated to common stock by the weighted-average common stock outstanding, excluding the weighted-average unvested restricted stock, adjusted for the dilutive effect of the stock options. Diluted EPS reflects the potential dilution that could occur if options or other contracts to issue common stock were exercised or converted into common stock, or resulted in the issuance of common stock that then shared in the earnings of the entity.
Transfers of Financial Assets	Transfer of Financial Assets Transfers of financial assets are accounted for sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Share-Based Compensation	Share-Based Compensation The Company recognizes the cost of employee services received in exchange for stock options and restricted stock awards (“RSAs”), based on the grant date fair value of those awards. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company's common stock at the date of grant is used for RSAs. This cost is recognized in income over the period which an employee is required to provide services in exchange for the award, generally the vesting period.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. Interest and penalties related to uncertain tax positions are recorded as part of income tax expense. A valuation allowance is established to reduce the deferred tax asset to the level at which it is more likely than not that the tax benefits will be realized. Realization of tax benefits of deductible temporary differences and carry-forwards depends on having sufficient taxable income of an appropriate character and in the appropriate periods. The Company has adopted FASB ASC 740-10, Income Taxes - Overall that clarifies the accounting for uncertainty in tax positions taken or expected to be taken on a tax return and provides that the tax effects from an uncertain tax position can be recognized in the consolidated financial statements only if, based on its merits, the position is more likely than not to be sustained on audit by taxing authorities. Interest and penalties related to uncertain tax positions are recorded as part of income tax expense. The Company elected to early adopt FASB Accounting Standard Update (“ASU”) 2018-02, Income Statement - Reporting Comprehensive Income as of and for the year ended December 31, 2017, which allows entities to reclassify the stranded tax effects as a result of applying the Tax Cuts and Jobs Act from accumulated other comprehensive income (loss) to retained earnings. As a result of the adoption, the Company recorded a decrease in accumulated other comprehensive income of $242 thousand and an increase in retained earnings for the same amount to eliminate the stranded tax effects at that date from the reduction in the federal statutory tax rate that was enacted in December 22, 2017 and became effective January 1, 2018.
Commitments and Contingencies	Commitments and Contingencies In the ordinary course of business, the Company enters into off-balance sheet financial instruments consisting of commitments to extend credit, commercial letters of credit, and standby letters of credit as described in Note 16. Such financial instruments are recorded in the consolidated financial statements when they are funded or related fees are incurred or received.
Fair Value Measurement	Fair Value Measurement Fair value is the exchange price that would be received for an asset or paid to transfer a liability (i.e., an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Current accounting guidance establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs when measuring fair value. The guidance describes three levels of inputs that may be used to measure fair value: • Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2: Significant observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.
Adopted Accounting Pronouncements and Recent Accounting Pronouncements Not Yet Adopted	Adopted Accounting Pronouncements During the year ended December 31, 2019 , the following accounting pronouncements applicable to the Company were adopted: In February 2016, the FASB issued Accounting Standard Update (“ASU”) 2016-02, “Leases (Topic 842).” In July 2018, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842, Leases,” and ASU 2018-11, “Leases Topic 842, Targeted Improvements,” to provide additional clarification, implementation, and transition guidance on certain aspects of ASU 2016-02. The amendments in ASU 2016-02 require lessees to recognize lease assets and lease liabilities for both leases classified as operating leases and finance leases, except leases with a term of 12 months or less where lessees are permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. For leases with a term of greater than 12 months, lessees are required to recognize a liability to make lease payments and a right-of-use assets representing its right to use the underlying asset for the lease term measured at the present value of the lease payments. ASU 2016-02 and ASU 2018-10 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for a public business entity. Under ASU 2018-11, an additional transition option was provided that would allow entities to not apply the new guidance in the comparative periods they present in their financial statements in the year of adoption. Under this optional transition method, entities will be allowed to continue using and presenting leases under Accounting Standard Codification (“ASC”) 840 for prior years’ comparative periods and then prospectively adopt ASC 842 on January 1, 2019, recognizing a cumulative-effect adjustment to the opening balance of retained earnings. The Company adopted this guidance in the first quarter of 2019 using the optional transition method with a cumulative effect adjustment to retained earnings without restating prior period financial statements for comparable amounts. The Company elected the package of practical expedients permitted under the transition guidance within this ASU, which allowed the Company to carry forward the historical lease classification. The Company completed its review of its existing lease contracts and service contracts that may include embedded leases, and updated processes and internal controls for leasing activities. The Company recognized right-of-use lease assets and liabilities of $9.6 million and $10.6 million , respectively, with a cumulative effect adjustment of $53 thousand to retained earnings at the date of adoption. Adoption of this ASU did not have a material impact on the Company’s consolidated financial statements other than the recognition of right-of-use lease assets and liabilities. See Note 6 for additional information. In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” The amendments in this ASU shorten the amortization period for certain callable debt securities acquired at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount, which continue to be amortized to maturity. Public business entities must prospectively apply the amendments in this ASU to annual periods beginning after December 15, 2018, including interim periods. Adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted The following are recently issued accounting pronouncements applicable to the Company that have not yet been adopted: In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326).” The amendments in this ASU require that entities change the impairment model for most financial assets that are measured at amortized cost and certain other instruments from an incurred loss model to an expected loss model. Under this model, entities will estimate credit losses over the entire contractual term of the instrument from the date of initial recognition of that instrument. It includes financial assets such as loan receivables, held-to-maturity debt securities, net investment in leases that are not accounted for at fair value through net income, and certain off-balance sheet credit exposures. This ASU is effective for public business entities that are SEC filers for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In 2019, the FASB amended this ASU, which delays the effective date to 2023 for certain SEC filers that are Smaller Reporting Companies, which would apply to the Company. The Company plans to adopt this ASU at the delayed effective date of 2023.
