Nature of Business

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business	Nature of Business Organization Pacific Mercantile Bancorp (“PMBC”) is a bank holding company which, through its wholly owned subsidiary, Pacific Mercantile Bank (the “Bank”), is engaged in the commercial banking business in Southern California. PMBC is registered as a one bank holding company under the United States Bank Holding Company Act of 1956, as amended, and, as such, is regulated by the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) and the Federal Reserve Bank of San Francisco (“FRBSF”) under delegated authority from the Federal Reserve Board. Substantially all of our operations are conducted and substantially all of our assets are owned by the Bank, which accounts for substantially all of our consolidated revenues, expenses, and income. The Bank provides a full range of banking services to middle-market businesses and professionals primarily in Orange, Los Angeles, San Bernardino and San Diego counties in Southern California and is subject to competition from, among other things, other banks and financial institutions and from financial services organizations conducting operations in those same markets. The Bank is chartered by the California Department of Financial Protection and Innovation under the Division of Financial Institutions and is a member of the FRBSF. In addition, the deposit accounts of the Bank’s customers are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to the maximum amount allowed by law. During the third quarter of 2018, PMBC dissolved its wholly-owned subsidiary, PM Asset Resolution, Inc. ("PMAR"), which was established for the purpose of purchasing certain non-performing loans and other real estate from the Bank and thereafter collecting or disposing of those assets. Prior to PMAR being dissolved, all assets were liquidated and returned to PMBC. PMBC, the Bank and PMAR are sometimes referred to, together, on a consolidated basis, as the “Company” or as “we”, “us” or “our”.

Significant Accounting Policies

Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies The accompanying consolidated financial statements have been prepared in accordance with the instructions of the U.S. Securities and Exchange Commission (the “SEC”) to Form 10-K and in accordance with generally accepted accounting principles in effect in the United States (“GAAP”), on a basis consistent with prior periods. Use of Estimates The preparation of the financial statements in conformity with GAAP requires us to make certain estimates and assumptions that could affect the reported amounts of certain of our assets, liabilities, and contingencies at the date of the financial statements and the reported amounts of our revenues and expenses during the reporting periods. Material estimates that are particularly susceptible to changes in the near term relate primarily to our determinations of the allowance for loan and lease losses (“ALLL”), the fair values of securities available for sale, and the determination of a valuation allowance pertaining to deferred tax assets. If circumstances or financial trends on which those estimates were based were to change in the future or there were to occur any currently unanticipated events affecting the amounts of those estimates, our future financial position or results of operations could differ, possibly materially, from those expected at the current time. Principles of Consolidation Our consolidated financial statements for the years ended December 31, 2020, 2019 and 2018 include the accounts of PMBC, the Bank and PMAR. All significant intercompany balances and transactions were eliminated in consolidation. Cash and Cash Equivalents For purposes of the statements of cash flow, cash and cash equivalents consist of cash and due from banks, interest bearing demand deposits with the FRBSF, federal funds sold and interest-bearing deposits, with original maturities of 90 days or less, with financial institutions. Generally, federal funds are sold for one-day periods. As of December 31, 2020 and 2019, the Bank maintained required reserves with FRBSF of approximately $0 and $3,856,000, respectively, which are included in cash and due from banks in the accompanying consolidated statements of financial condition. Federal Home Loan Bank Stock and Federal Reserve Bank Stock The Bank, as a member of the Federal Home Loan Bank System, is required to maintain an investment in capital stock of the Federal Home Loan Bank of San Francisco (“FHLB”) in varying amounts based on asset size and on amounts borrowed from the FHLB. Because no ready market exists and there is no quoted market value for this stock, the Bank’s investment in this stock is carried at cost. The Bank also maintains an investment in capital stock of the FRBSF, which is carried at cost because no ready market exists and there is no quoted market value for this stock. Securities Available for Sale, at Fair Value Securities available for sale are those which we intend to hold for an indefinite period of time, but which may be sold in response to changes in liquidity needs, changes in interest rates, changes in prepayment risks and other similar factors. These securities are recorded at fair value, with unrealized gains and losses excluded from earnings and reported as other comprehensive income or loss, net of taxes. Purchased premiums and discounts are recognized as interest income using the interest method over the term of these securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. Declines in the fair value of these securities below their cost which are other-than-temporary are reflected in earnings as realized losses. In determining other-than-temporary losses, we consider a number of factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether we have the intent to sell the security or it is more likely than not that we will be required to sell the security before its anticipated recovery. A high degree of subjectivity and judgment is involved in assessing whether an other-than-temporary decline exists and such assessments are based on information available to us at the time we make such assessments. We recognize other-than-temporary impairments (“OTTI”) to our available-for-sale debt securities in accordance with FASB ASC 320-10. When there are credit losses associated with, but we have no intention to sell, an impaired debt security, and it is more likely than not that we will not have to sell the security before recovery of its cost basis, we will separate the amount of impairment, or OTTI, between the amount that is credit-related and the amount that is related to non-credit factors. Credit-related impairments are recognized in our consolidated statements of operations. Any non-credit-related impairments are recognized and reflected in other comprehensive income in our consolidated statements of financial condition. Loans and Allowance for Loan and Lease Losses Loans that we intend and have the ability to hold for the foreseeable future or until maturity or pay-off are stated at their respective principal amounts outstanding, net of unearned income. Interest is accrued daily as earned, except where reasonable doubt exists as to collectability of the loan. A loan with principal or interest that is 90 days or more past due, based on its contractual payment due dates, is placed on nonaccrual status, in which case accrual of interest is discontinued, except that we may elect to continue the accrual of interest when the estimated net realizable value of collateral securing the loan is expected to be sufficient to enable us to recover both principal and accrued interest and those loans are in the process of collection. Generally, interest payments received on nonaccrual loans are applied to principal. Once all principal has been received by us, any additional interest payments are recognized as interest income on a cash basis. An ALLL is established by means of a provision for loan and lease losses that is charged against income. If we conclude that the collection, in full, of the carrying amount of a loan has become unlikely, the loan, or the portion thereof that is believed to be uncollectible, is charged against the ALLL. We carefully monitor changing economic conditions, the loan portfolio by category, the financial condition of borrowers and the history of the performance of the loan portfolio in determining the adequacy of the ALLL. Additionally, as the volume of loans increases, additional provisions for loan losses may be required to maintain the allowance at levels deemed adequate. Moreover, if economic conditions were to deteriorate, causing the risk of loan losses to increase, it would become necessary to increase the allowance to an even greater extent, which would necessitate additional provisions that would be charged to income. We also evaluate the unfunded portion of loan commitments and establish a loss reserve, included in other liabilities, for such unfunded commitments through a charge against noninterest expense. The loss reserve for unfunded loan commitments was $350,000 at December 31, 2020 and 2019. The ALLL is based on estimates, and ultimate loan losses may vary from current estimates. These estimates are reviewed periodically and, as adjustments become necessary, they are recorded in earnings in the periods in which they become known. Impaired Loans A loan is generally classified as impaired when, in management’s opinion, the principal or interest will not be collectible in accordance with its contractual terms. We measure and reserve for impairment on a loan-by-loan basis using either the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral if the loan is collateral dependent. We exclude smaller, homogeneous loans, such as consumer installment loans and lines of credit, from these impairment calculations. Also, loans that experience insignificant payment delays or shortfalls are generally not considered impaired. Restructured Loans We sometimes modify or restructure loans when the borrower is experiencing financial difficulties by making a concession to the borrower in the form of changes in the amortization terms, reductions in the interest rates, the acceptance of interest only payments and, in limited cases, concessions to the outstanding loan balances. These loans are classified as troubled debt restructurings (“TDRs”) and considered impaired loans. TDRs are loans modified for the purpose of alleviating temporary impairments to the borrower’s financial condition or cash flows. A workout plan between us and the borrower is designed to provide a bridge for borrower cash flow shortfalls in the near term. A TDR loan may be returned to accrual status when the loan is brought current, has performed in accordance with the contractual restructured terms for a time frame of at least six months and the ultimate collectability of the total contractual restructured principal and interest in no longer in doubt. These loans, while no longer considered a TDR, are still considered impaired loans. The CARES Act, passed by Congress during the first quarter of 2020 in response to COVID-19, allows us to provide assistance in the form of loan modifications to our borrowers negatively impacted by the pandemic. These loans are not classified as TDRs or considered impaired if the borrowers were current as of December 31, 2019 and their ability to pay was impacted by COVID-19. The loan modifications provided were limited to payment deferrals and the majority of borrowers that received loan deferrals earlier in the year have now returned to normal payment schedules. As of December 31, 2020, we had 16 loans with an outstanding balance of $20.4 million that were under a payment deferral. Loan Origination Fees and Costs Loan origination fees and related direct costs for loans held for investment are deferred and amortized to interest income as an adjustment to yield over the respective lives of the loans using the effective interest method, except for loans that are revolving or short-term in nature for which the straight line method is used, which approximates the interest method. Investment in Unconsolidated Subsidiaries Investment in unconsolidated subsidiaries is stated at cost. The unconsolidated subsidiaries are comprised of two grantor trusts established in 2002 and 2004 in connection with our issuance of subordinated debentures in each of those years. Prior to 2004, we organized two business trusts, under the names PMB Statutory Trust III and PMB Capital Trust III, to facilitate our issuance of $7.2 million and $10.3 million, respectively, principal amount of junior subordinated debentures with maturity dates in 2032 and 2034, respectively. The principal amounts remain outstanding as of December 31, 2020. Other Real Estate Owned Other real estate owned (“OREO”) consists of real properties acquired by us through foreclosure or in lieu of foreclosure in satisfaction of loans. OREO is recorded at fair value less estimated selling costs at the time of acquisition or foreclosure. Loan balances in excess of fair value, less selling costs, are charged to the ALLL prior to foreclosure. Any subsequent operating expenses or income, reductions in estimated fair values and gains or losses on disposition of such properties are charged or credited to current operations. Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation and amortization which are charged to expense on a straight-line basis over the estimated useful lives of the assets or, in the case of leasehold improvements, over the term of the leases, whichever is shorter. For income tax purposes, accelerated depreciation methods are used. Maintenance and repairs are charged directly to expense as incurred. Improvements to premises and equipment that extend their useful lives are capitalized. When such an asset is disposed of, the applicable costs and accumulated depreciation thereon are removed from the accounts and any resulting gain or loss is included in current operations. Rates of depreciation and amortization are based on the following estimated useful lives: Furniture and equipment Three Leasehold improvements Lesser of the lease term or estimated useful life Income Taxes Deferred income taxes and liabilities are determined using the asset and liability method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax basis of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. We record as a deferred tax asset on our balance sheet an amount equal to the tax credit and tax loss carryforwards and tax deductions ("tax benefits") that we believe will be available to us to offset or reduce the amount of our income taxes in future periods. Under applicable federal and state income tax laws and regulations, such tax benefits will expire if not used within specified periods of time. Accordingly, the ability to fully use our deferred tax asset depends on the amount of taxable income that we generate during those time periods. At least once each year, or more frequently, if warranted, we make estimates of future taxable income that we believe we are likely to generate during those future periods. If we conclude, on the basis of those estimates and the amount of the tax benefits available to us, that it is more likely than not that we will be able to fully utilize those tax benefits prior to their expiration, we recognize the deferred tax asset in full on our balance sheet. On the other hand, if we conclude on the basis of those estimates and the amount of the tax benefits available to us that it has become more likely than not that we will be unable to utilize those tax benefits in full prior to their expiration, then, we would establish (or increase any existing) valuation allowance to reduce the deferred tax asset on our balance sheet to the amount which we believe we are more likely than not to be able to utilize. Such a reduction is implemented by recognizing a non-cash charge that would have the effect of increasing the provision, or reducing any credit, for income taxes that we would otherwise have recorded in our statement of operations. The determination of whether and the extent to which we will be able to utilize our deferred tax asset involves significant management judgments and assumptions that are subject to period to period changes as a result of changes in tax laws, changes in market or economic conditions that could affect our operating results or variances between our actual operating results and our projected operating results, as well as other factors. Uncertain tax positions that meet the more likely than not recognition threshold are measured to determine the amount of benefit to recognize. An uncertain tax position is measured at the largest amount of benefit that management believes has a greater than 50% likelihood of realization upon settlement. Earnings (Loss) Per Share Basic income (loss) per share for any fiscal period is computed by dividing net income (loss) allocable to our common shareholders for such period by the weighted average number of common shares outstanding during that period. Fully diluted income (loss) per share reflects the potential dilution that could have occurred assuming the conversion of any convertible securities into common stock at conversion prices, and the exercise of all outstanding options and warrants to purchase shares of our common stock at exercise prices, that were less than the market price of our shares, thereby increasing the number of shares outstanding during the period, and is determined using the treasury method. Although accumulated undeclared dividends on our preferred stock are not recorded in the accompanying consolidated statement of operations, such dividends are included for purposes of computing earnings (loss) per share available to our common shareholders. Stock Option Plans We follow Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 718-10, Share-Based Payment , which requires entities that grant stock options or other equity compensation awards to employees to recognize in their financial statements the fair values of those options or share awards as compensation cost over their requisite service (vesting) periods of those options or share awards. Since stock-based compensation cost that is recognized in the statements of operations is to be determined based on the equity compensation awards that we expect will ultimately vest, that compensation expense is reduced for any forfeitures of unvested options or unvested share awards that typically occur due primarily to terminations of employment of optionees or recipients of such share awards. In accordance with Accounting Standard Update (“ASU”) 2016-09, forfeitures are recognized as they occur instead of applying an estimated forfeiture rate to each grant, which was the previous practice. For purposes of the determination of stock-based compensation expense for the year ended December 31, 2020, we recognized actual forfeitures of 15,906, 28,402 and zero shares subject to the stock option, restricted stock, and stock unit awards, respectively, that were granted to officers and other employees. Comprehensive Income (Loss) Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. However, certain changes in assets and liabilities, such as unrealized gains and losses on securities available for sale, are reported as a separate component of the equity in the accompanying consolidated statement of financial condition, net of income taxes, and such items, along with net income, are components of comprehensive income (loss). Segment Reporting During the years ended December 31, 2020, 2019 and 2018, we had one reportable segment, which was our commercial banking division, and one non-reportable segment which was our discontinued operations related to our mortgage banking division. In connection with our exit from the mortgage banking business in 2013, the revenues and expenses of our mortgage banking division have been classified as discontinued operations for all periods presented. Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which requires the measurement of all expected credit losses for financial assets held at the reporting date, based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions will now use forward-looking information to better inform their credit loss estimates. Additionally, the ASU amends the accounting guidance for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. On November 15, 2019, the FASB issued ASU 2019-10, " Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates " which finalizes various effective date delays for private companies, not-for-profit organizations, and smaller reporting companies applying the credit losses (CECL), leases, and hedging standards. The effective date for smaller reporting companies has been delayed from the interim and annual periods beginning after December 15, 2020 to the interim and annual periods beginning after December 15, 2022. Early adoption is permitted for interim and annual periods beginning after December 15, 2018. Upon issuance of the final ASU, we plan to adopt this guidance on January 1, 2023 and expect that it will have a material impact on the determination of our ALLL. We are unable to estimate the expected impact to the ALLL upon adoption due to various factors, primarily the fine tuning of our qualitative assumptions used within our preliminary model, uncertainty regarding economic conditions and the size and mix of our loan portfolio at the time of adoption, which could impact our historical loss factors. We are currently working with our existing ALLL software provider on further developing the model to perform the ALLL calculations upon adoption and we believe that we currently have in place the internal team capable of handling this implementation. In December 2019, the FASB issued ASU 2019-12, " Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes," which eliminates certain exceptions to the guidance in ASC 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance is effective for public business entities for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years. We adopted this guidance on January 1, 2021, and do not expect any material impact related to this pronouncement. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which provides temporary optional expedients to ease the financial reporting burdens of the expected market transition from London Interbank Offered Rate (LIBOR) to an alternative reference rate such as Secured Overnight Financing Rate (SOFR). The guidance was effective upon issuance and generally can be applied through December 31, 2022. We are currently evaluating this guidance to determine the date of adoption and the impact on the Company. In October 2020, the FASB issue ASU 2020-08, "Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs," which clarified that for each reporting period, an entity should reevaluate whether a callable debt security is within the scope of paragraph 310-20-35-33 of the FASB’s Accounting Standards Codification. This guidance is effective for public business entities for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years. We adopted this guidance on January 1, 2021. Subsequent Events Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. The Company recognizes in the financial statements the effects of all subsequent events that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing the financial statements. The Company’s financial statements do not recognize subsequent events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after the balance sheet date and before financial statements are available to be issued. The Company has evaluated events subsequent to the balance sheet date through the date these consolidated financial statements were filed with the SEC.

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2020
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Under FASB ASC 820-10, we group assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: Level 1 Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2 Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. Risks with Fair Value Measurements Fair value estimates are made at a discrete point in time based on relevant market information and other information about the financial instruments. Because no active market exists for a significant portion of our financial instruments, fair value estimates are based in large part on judgments we make primarily regarding current economic conditions, risk characteristics of various financial instruments, prepayment rates, and future expected loss experience. These estimates are subjective in nature and invariably involve some inherent uncertainties. Additionally, the occurrence of unexpected events or changes in circumstances can occur that could require us to make changes to our assumptions and which, in turn, could significantly affect and require us to make changes to our previous estimates of fair value. In addition, the fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of existing and anticipated future client relationships and the value of assets and liabilities that are not considered financial instruments, such as premises and equipment and OREO. Measurement Methodology Cash and Cash Equivalents. The fair value of cash and cash equivalents approximates its carrying value. Interest-Bearing Deposits with Financial Institutions. The fair values of interest-bearing deposits maturing within one year approximate their carrying values. FHLB and FRBSF Stock. The Bank is a member of the Federal Home Loan Bank of San Francisco (“FHLB”) and the FRBSF. As members, we are required to own stock of the FHLB and the FRBSF, the amount of which is based primarily on the level of our borrowings from those institutions. We also have the right to acquire additional shares of stock in either or both of the FHLB and the FRBSF. During the year ended December 31, 2020, we purchased no FHLB or FRBSF stock. No shares of FHLB or FRBSF stock were called during the year ended December 31, 2020. During the year ended December 31, 2019, we purchased no FHLB or FRBSF stock. No shares of FHLB stock or FRBSF stock were called during the year ended December 31, 2019. The fair values of the FHLB and FRBSF stock are equal to their respective carrying amounts, are classified as restricted securities and are periodically evaluated for impairment based on our assessment of the ultimate recoverability of our investments in that stock. Any cash or stock dividends paid to us on such stock are reported as income. Investment Securities Available for Sale. Fair value measurement for our investment securities available for sale is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 investment securities include those traded on an active exchange, such as the New York Stock Exchange, and U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets. Level 2 investment securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. Securities classified as Level 3 include asset-backed securities in less liquid markets. Equity Investments Without Readily Determinable Fair Value . Equity investments without readily determinable fair value are accounted for under the measurement alternative method of accounting. These investments are measured at cost, less any impairment, plus or minus any changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Any cash or stock dividends paid to us on such investments are reported as noninterest income. Impaired Loans . Loans measured for impairment are measured at an observable market price (if available), or the fair value of the loan’s collateral (if the loan is collateral dependent). The fair value of an impaired loan may be estimated using one of several methods, including collateral value, market value of similar debt, liquidation value and discounted cash flows. Those impaired loans not requiring a specific loan loss reserve represent loans for which the fair value of the expected repayments or collateral exceeds the recorded investments in such loans. When the fair value of the collateral is based on an observable market price or a current appraised value, we record the impaired loan at Level 2. When an appraised value is not available or we determine that the fair value of the collateral is further impaired below the appraised value and there is no observable market price, we record the impaired loan at Level 3. Loans . The fair value for loans with variable interest rates less a credit discount is the carrying amount. The fair value of fixed rate loans is derived by calculating the present value of expected future cash flows discounted at the loan’s original interest rate by the various homogeneous categories of loans. All loans have been adjusted to reflect changes in credit risk and represent the exit price of the loans. Changes are not recorded directly as an adjustment to current earnings or comprehensive income, but rather as an adjustment component in determining the overall adequacy of the loan loss reserve. Other Real Estate Owned. OREO is reported at its net realizable value (fair value less estimated costs to sell) at the time any real estate collateral is acquired by the Bank in satisfaction of a loan. Subsequently, OREO is carried at the lower of carrying value or fair value less estimated costs to sell. Fair value is determined based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price or a current appraised value, we record the foreclosed asset at Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, we record the foreclosed asset at Level 3. Other Foreclosed Assets. Other foreclosed assets are reported at their net realizable value (fair value less estimated costs to sell) at the time any collateral other than real estate is acquired by the Bank in satisfaction of a loan. Subsequently, other foreclosed assets are carried at the lower of carrying value or fair value less estimated costs to sell. Fair value is determined based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price or a current appraised value, we record the foreclosed asset at Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, we record the foreclosed asset at Level 3. Deposits. Deposits are carried at historical cost. The carrying amounts of deposits from savings and money market accounts are deemed to approximate fair value as they either have no stated maturities or short-term maturities. Certificates of deposit are estimated utilizing discounted cash flow techniques. The interest rates applied are rates currently being offered for similar certificates of deposit. Borrowings. The fair value of borrowings is the carrying amount for those borrowings that mature on a daily basis. The fair value of term borrowings is derived by calculating the discounted value of future cash flows expected to be paid out by the Company. We classify our borrowings in Level 2 of the fair value hierarchy. Junior Subordinated Debentures. The fair value of the junior subordinated debentures is based on quoted market prices of the underlying securities. These securities are variable rate in nature and repriced quarterly. We classify our junior subordinated debentures in Level 2 of the fair value hierarchy. Commitments to Extend Credit and Standby Letters of Credit. The fair value of commitments to extend credit and standby letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. Interest Receivable and Interest Payable. The carrying amounts of our accrued interest receivable and accrued interest payable are deemed to approximate fair value. Assets Recorded at Fair Value on a Recurring Basis The following tables show the recorded amounts of assets and liabilities measured at fair value on a recurring basis at December 31, 2020 and 2019. At December 31, 2020 Total Level 1 Level 2 Level 3 (Dollars in thousands) Assets at Fair Value: Debt securities available for sale Commercial mortgage backed securities issued by U.S. Agencies $ 20,673 $ — $ 20,673 $ — Residential mortgage backed securities issued by U.S. agencies 14,436 — 14,436 — Corporate subordinated debt 7,074 — 7,074 — Total debt securities available for sale at fair value $ 42,183 $ — $ 42,183 $ — At December 31, 2019 Total Level 1 Level 2 Level 3 (Dollars in thousands) Assets at Fair Value: Debt securities available for sale Commercial mortgage backed securities issued by U.S. Agencies $ 9,229 $ — $ 9,229 $ — Residential mortgage backed securities issued by U.S. agencies 19,115 — 19,115 — Total debt securities available for sale $ 28,344 $ — $ 28,344 $ — Assets Recorded at Fair Value on a Nonrecurring Basis We may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets. Information regarding assets measured at fair value on a nonrecurring basis is set forth in the table below. At December 31, 2020 At December 31, 2019 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Assets at Fair Value: (Dollars in thousands) Impaired loans $ 39,916 $ — $ — $ 39,916 $ 15,682 $ — $ — $ 15,682 Other foreclosed assets 231 — 231 — 164 — 164 — Total $ 40,147 $ — $ 231 $ 39,916 $ 15,846 $ — $ 164 $ 15,682 Significant Unobservable Inputs and Valuation Techniques of Level 3 Fair Value Measurements For our fair value measurements classified in Level 3 of the fair value hierarchy as of December 31, 2020, a summary of the significant unobservable inputs and valuation techniques is as follows: Fair Value Measurement as of December 31, 2020 Valuation Techniques Unobservable Inputs Range Weighted Average (Dollars in thousands) Assets Impaired loans 39,916 Third-Party Pricing Discounted cash flow N/A (2) $ 39,916 (1) As part of our process, we obtain appraisals for our various properties included within impaired loans which primarily rely upon market comparisons. These market comparisons support our assumption that the carrying value of the respective loans either requires or does not require additional impairment. (2) As of December 31, 2020, there has been no change to our valuation techniques or the types of unobservable inputs used in the calculation of fair value from December 31, 2019.

Investments, Debt and Equity Securities [Abstract]
Investments	Investments Securities Available For Sale, at Fair Value The following table sets forth the major components of securities available for sale and compares the amortized costs and estimated fair market values of, and the gross unrealized gains and losses on, these securities at December 31, 2020 and December 31, 2019: December 31, 2020 December 31, 2019 Amortized Gross Unrealized Estimated Amortized Gross Unrealized Estimated Gain Loss Gain Loss (Dollars in thousands) Securities Available for Sale Commercial mortgage backed securities issued by U.S. Agencies (1) 20,585 214 (126) 20,673 9,147 128 (46) 9,229 Residential mortgage backed securities issued by U.S. Agencies (2) 14,061 379 (4) 14,436 19,380 12 (277) 19,115 Corporate subordinated debt 7,035 42 (3) 7,074 — — — — Total $ 41,681 $ 635 $ (133) $ 42,183 $ 28,527 $ 140 $ (323) $ 28,344 (1) Secured by first liens on commercial apartment building mortgages. (2) Secured by closed-end first liens on 1-4 family residential mortgages. At December 31, 2020 and 2019, U.S. agency mortgage backed securities and collateralized mortgage obligations with an aggregate fair market value of $2.0 million and $9.2 million, respectively, were pledged to secure FHLB borrowings, repurchase agreements, local agency deposits and treasury, tax and loan accounts. The amortized cost and estimated fair values of securities available for sale at December 31, 2020 and December 31, 2019 are shown in the tables below by contractual maturities taking into consideration historical prepayments based on the prior twelve months of principal payments. Expected maturities will differ from contractual maturities and historical prepayments, particularly with respect to collateralized mortgage obligations, primarily because prepayment rates are affected by changes in conditions in the interest rate market and, therefore, future prepayment rates may differ from historical prepayment rates.

Securities available for sale of $4.5 million were purchased during the year ended December 31, 2018. We sold $3.5 million of securities available for sale during the year ended December 31, 2020, for a total net gain on sale of $171 thousand. We had no sales of securities available for sale during the year ended December 31, 2019. During the year 2018, we had $2.1 million of proceeds from sales of securities available for sale for a total net loss of $53 thousand. The tables below indicate, as of December 31, 2020 and December 31, 2019, the gross unrealized losses and fair values of our investments, aggregated by investment category, and length of time that the individual securities have been in a continuous unrealized loss position. Securities with Unrealized Loss at December 31, 2020 Less than 12 months 12 months or more Total Fair Value Unrealized Fair Value Unrealized Fair Value Unrealized (Dollars in thousands) Commercial mortgage backed securities issued by U.S. Agencies 7,483 (126) — — 7,483 (126) Residential mortgage backed securities issued by U.S. Agencies 68 (1) 126 (3) 194 (4) Corporate subordinated debt 4,032 (3) — — 4,032 (3) Total $ 11,583 $ (130) $ 126 $ (3) $ 11,709 $ (133) Securities with Unrealized Loss at December 31, 2019 Less than 12 months 12 months or more Total Fair Value Unrealized Fair Value Unrealized Fair Value Unrealized (Dollars in thousands) Commercial mortgage backed securities issued by U.S. Agencies 4,472 (46) — — 4,472 (46) Residential mortgage backed securities issued by U.S. Agencies 76 (1) 15,965 (276) 16,041 (277) Total $ 4,548 $ (47) $ 15,965 $ (276) $ 20,513 $ (323) We regularly monitor investments for significant declines in fair value. We have determined that declines in the fair values of these investments below their respective amortized costs, as set forth in the tables above, are temporary because (i) those declines were due to interest rate changes and not to a deterioration in the creditworthiness of the issuers of those investment securities, and (ii) we have the ability to hold those securities until there is a recovery in their values or until their maturity. Through the impairment assessment process, we determined that there were no available-for-sale debt securities that were other-than-temporarily impaired at December 31, 2020. We recorded no impairment credit losses on available-for-sale debt securities in our consolidated statements of operations for the year ended December 31, 2020 and 2019. We have made a determination that the remainder of our securities with respect to which there were unrealized losses as of December 31, 2020 are not other-than-temporarily impaired, because we have concluded that we have the ability to continue to hold those securities until their respective fair market values increase above their respective amortized costs or, if necessary, until their respective maturities. In reaching that conclusion we considered a number of factors and other information, which included: (i) the significance of each such security, (ii) the amount of the unrealized losses attributable to each such security, (iii) our liquidity position, (iv) the impact that retention of those securities could have on our capital position and (v) our evaluation of the expected future performance of these securities (based on the criteria discussed above). Equity Investments Without Readily Determinable Fair Value As of December 31, 2020, we had three investments in limited partnerships without a readily determinable fair value. As of December 31, 2020, we owned less than 3% of the total investment in each partnership. Under ASU 2016-01, we elected to measure these equity investments using the measurement alternative, which requires that these investments are measured at cost, less any impairment, plus or minus any changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. During the year ended December 31, 2020, these investments were not impaired and there were no observable price changes. As a result, the balance shown below as of December 31, 2020 represents the cost of the investments and is included within other assets on the consolidated statements of financial condition. During the year ended December 31, 2020, we had $556 thousand of capital contributions to these investments, and no return of principal. We had $876 thousand of capital contributions to these investments during the year ended December 31, 2019, and no return of principal. As of December 31, 2020 and December 31, 2019, our equity investments without readily determinable fair value were as follows: December 31, 2020 December 31, 2019 (Dollars in thousands) Equity investments without readily determinable fair value $ 2,673 $ 2,117

There were $5.7 million of loans 90 days or more past due and still accruing interest at December 31, 2020 and zero outstanding at December 31, 2019. In certain instances, when a loan is placed on non-accrual status, previously accrued but unpaid interest is reversed against current income. Subsequent collections of cash are applied as principal reductions when received, except when the ultimate collectability of principal is probable, in which case such payments are applied to accrued and unpaid interest, which is credited to income. Non-accrual loans may be restored to accrual status when principal and interest become current and full repayment becomes expected. The following table provides information with respect to loans on nonaccrual status, by portfolio type, as of December 31, 2020 and 2019: December 31, 2020 2019 (Dollars in thousands) Nonaccrual loans: Commercial loans $ 30,928 $ 9,101 Commercial real estate loans – owner occupied 6,978 6,507 Commercial real estate loans – all other 1,836 — Consumer loans 174 74 Total (1) $ 39,916 $ 15,682 (1) Nonaccrual loans may include loans that are currently considered performing loans.

We measure for impairments on a loan-by-loan basis, using either the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral if the loan is collateral dependent. The following table sets forth information regarding impaired loans, at December 31, 2020 and December 31, 2019: December 31, 2020 2019 (Dollars in thousands) Impaired loans: Nonaccruing loans $ 33,204 $ 15,682 Nonaccruing restructured loans 6,712 — Total impaired loans $ 39,916 $ 15,682 Impaired loans less than 90 days delinquent and included in total impaired loans $ 34,085 $ 15,149 The table below contains additional information with respect to impaired loans, by portfolio type, as of December 31, 2020 and 2019: December 31, 2020 December 31, 2019 Recorded Investment Unpaid Principal Balance Related Allowance (1) Recorded Investment Unpaid Principal Balance Related Allowance (1) (Dollars in thousands) No allowance recorded: Commercial loans, excluding PPP $ 10,970 $ 19,530 $ — $ 7,996 $ 12,090 $ — Commercial real estate loans – owner occupied 6,978 7,633 — 6,507 6,784 — Commercial real estate loans – all other 1,836 1,837 — — — — Consumer loans 174 197 — 74 101 — Total $ 19,958 $ 29,197 $ — $ 14,577 $ 18,975 $ — With allowance recorded: Commercial loans, excluding PPP $ 19,958 $ 20,040 $ 2,711 $ 1,105 $ 1,122 $ 561 Total $ 19,958 $ 20,040 $ 2,711 $ 1,105 $ 1,122 $ 561 Total Commercial loans, excluding PPP $ 30,928 $ 39,570 $ 2,711 $ 9,101 $ 13,212 $ 561 Commercial real estate loans – owner occupied 6,978 7,633 — 6,507 6,784 — Commercial real estate loans – all other 1,836 1,837 — — — — Consumer loans 174 197 — 74 101 — Total $ 39,916 $ 49,237 $ 2,711 $ 15,682 $ 20,097 $ 561 (1) When the discounted cash flows, collateral value or market price equals or exceeds the recorded investment in the loan, then specific reserves are not required to be set aside for the loan within the ALLL. This typically occurs when the impaired loans have been partially charged-off and/or there have been interest payments received and applied to the balance of the principal outstanding. At December 31, 2020 and December 31, 2019, there were $20.0 million and $14.6 million, respectively, of impaired loans for which no specific reserves had been allocated because these loans, in our judgment, were sufficiently collateralized. Of the impaired loans at December 31, 2020 for which no specific reserves were allocated, $8.7 million had been deemed impaired in the prior year. Average balances and interest income recognized on impaired loans, by portfolio type, for the year ended December 31, 2020, 2019 and 2018 were as follows: Year Ended December 31, 2020 2019 2018 Average Balance Interest Income Recognized Average Balance Interest Income Recognized Average Balance Interest Income Recognized (Dollars in thousands) No allowance recorded: Commercial loans, excluding PPP $ 9,307 $ 534 $ 3,828 $ 581 $ 4,289 $ 101 Commercial real estate loans – owner occupied 5,216 53 3,038 267 856 — Commercial real estate loans – all other 367 36 — — 370 — Residential mortgage loans – single family — — — — — — Consumer loans 138 5 69 3 48 — Total 15,028 628 6,935 851 5,563 101 With allowance recorded: Commercial loans, excluding PPP $ 5,032 $ 930 $ 221 $ 53 $ 96 $ — Total $ 5,032 $ 930 $ 221 $ 53 $ 96 $ — Total Commercial loans, excluding PPP $ 14,339 $ 1,464 $ 4,049 $ 634 $ 4,385 $ 101 Commercial real estate loans – owner occupied 5,216 53 3,038 267 856 — Commercial real estate loans – all other 367 36 — — 370 — Residential mortgage loans – single family — — — — — — Consumer loans 138 5 69 3 48 — Total $ 20,060 $ 1,558 $ 7,156 $ 904 $ 5,659 $ 101 The interest that would have been earned had the impaired loans remained current in accordance with their original terms was $1.8 million in 2020, $416 thousand in 2019 and $362 thousand in 2018. Troubled Debt Restructurings Pursuant to the FASB's ASU No. 2011-2, A Creditor's Determination of whether a Restructuring is a Troubled Debt Restructuring , the Company had $6.7 million TDRs at December 31, 2020 and zero at December 31, 2019. TDRs consist of loans to which modifications have been made for the purpose of alleviating temporary impairments of the borrower's financial condition and cash flows. Those modifications have come in the forms of changes in amortization terms, reductions in interest rates, interest only payments and, in limited cases, concessions to outstanding loan balances. The modifications are made as part of workout plans we enter into with the borrower that are designed to provide a bridge for the borrower's cash flow shortfalls in the near term. If a borrower works through the near term issues, then in most cases, the original contractual terms of the borrower's loan will be reinstated. TDRs do not include short term loan modifications made on a good faith basis in response to COVID-19. The following table presents loans restructured as TDRs during the years ended December 31, 2020, 2019 and 2018: Year Ended December 31, 2020 2019 2018 Number of Pre-Modification Post-Modification Number of Pre-Modification Post-Modification Number of Pre-Modification Post-Modification (Dollars in thousands) Nonperforming Commercial loans 4 3,298 2,085 — — — — — — Commercial real estate – owner occupied 1 3,851 4,627 — — — — — — Total nonperforming 5 7,149 6,712 — — — — — — Total troubled debt restructurings (1) 5 $ 7,149 $ 6,712 — $ — $ — — $ — $ — (1) No loans were restructured during the years ended December 31, 2019 or December 31, 2018.

The PPP loans are 100% guaranteed by the SBA and the principal and interest may be forgiven by the SBA if the borrower demonstrates that the loan proceeds were used as prescribed by the governing legislation and regulations during either an 8-week or 24-week period following funding (the "Covered Period"). Borrowers began submitting applications for forgiveness in the third quarter of 2020 and have until 10 months following the end of their Covered Period to apply. As of December 31, 2020, $51.3 million of the $281.0 million originated PPP loans have been forgiven by the SBA. At December 31, 2020 and 2019, real estate loans of approximately $434 million and $278 million, respectively, were pledged to secure borrowings obtained from the FHLB. At December 31, 2020 and 2019, commercial and consumer loans of $146 million and $210 million, respectively, were pledged to secure borrowings from the FRB to support our unfunded borrowing capacity. During the year ended December 31, 2020, we sold $5.8 million of Small Business Administration (SBA) loans at a premium for a net gain on sale of $547 thousand. During the year ended December 31, 2019, we sold $12.0 million of Small Business Administration (SBA) loans at a premium for a net gain on sale of $1.0 million. During the year ended December 31, 2018, we sold $15.1 million of commercial real estate loans at par value. During the year ended December 31, 2020, we purchased $10.4 million of commercial real estate - all other loans. During the year ended December 31, 2019, we purchased loans totaling $121.0 million, of which $81.0 million were multi-family mortgage and $39.9 million were consumer loans. We purchased $10.0 million of performing commercial real estate loans during the year ended December 31, 2018. Allowance for Loan and Lease Losses The ALLL represents our estimate of credit losses in our loan and lease portfolio that are probable and estimable at the balance sheet date. We employ economic models that are based on bank regulatory guidelines, industry standards and our own historical loan loss experience, as well as a number of more subjective qualitative factors, to determine both the sufficiency of the ALLL and the amount of the provisions that are required to increase or replenish the ALLL. The ALLL is first determined by (i) analyzing all classified loans (graded as “Substandard” or “Doubtful” under our internal asset quality grading parameters) on non-accrual status for loss exposure and (ii) establishing specific reserves as needed. ASC 310-10 defines loan impairment as the existence of uncertainty concerning collection of all principal and interest in accordance with the contractual terms of a loan. For collateral dependent loans, impairment is typically measured by comparing the loan amount to the fair value of collateral, less estimated costs to sell, with any “shortfall” amount charged off. Other methods can be used in estimating impairment, including market price and the present value of expected future cash flows discounted at the loan’s original interest rate. We are an active lender with the U.S. Small Business Administration and collection of a percentage of the loan balance of many of the loans originated is guaranteed. The ALLL reserves are calculated against the non-guaranteed loan balances. On a quarterly basis, we utilize a classification based loan loss migration model as well as review individual loans in determining the adequacy of the ALLL for homogenous pools of loans that are not subject to specific reserve allocations. Our loss migration analysis utilizes a series of nineteen staggered 16-quarter migration periods of loan loss history and industry loss factors to determine historical losses by classification category for each loan type, except certain consumer loans (automobile, mortgage and credit cards). We then apply these calculated loss factors, together with qualitative factors based on external economic conditions and trends and internal assessments, to the outstanding loan balances in each homogenous group of loans, and then, using our internal asset quality grading parameters, we grade the loans as “Pass,” “Special Mention,” “Substandard” or “Doubtful”. We analyze impaired loans individually. This grading is based on the credit classifications of assets as prescribed by government regulations and industry standards and is separated into the following groups: • Pass: Loans classified as pass include current loans performing in accordance with contractual terms, installment/consumer loans that are not individually risk rated, and loans which exhibit certain risk factors that require greater than usual monitoring by management. • Special Mention: Loans classified as special mention, while generally not delinquent, have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the Bank’s credit position at some future date. • Substandard: Loans classified as substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. There is a distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. • Doubtful: Loans classified as doubtful have all the weaknesses inherent in a substandard loan, and may also be at delinquency status and have defined weaknesses based on currently existing facts, conditions and values making collection or liquidation in full highly questionable and improbable. Set forth below is a summary of the activity in the ALLL, by portfolio type, during the years ended December 31, 2020, 2019 and 2018.

We measure for impairments on a loan-by-loan basis, using either the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral if the loan is collateral dependent. The following table sets forth information regarding impaired loans, at December 31, 2020 and December 31, 2019: December 31, 2020 2019 (Dollars in thousands) Impaired loans: Nonaccruing loans $ 33,204 $ 15,682 Nonaccruing restructured loans 6,712 — Total impaired loans $ 39,916 $ 15,682 Impaired loans less than 90 days delinquent and included in total impaired loans $ 34,085 $ 15,149 The table below contains additional information with respect to impaired loans, by portfolio type, as of December 31, 2020 and 2019: December 31, 2020 December 31, 2019 Recorded Investment Unpaid Principal Balance Related Allowance (1) Recorded Investment Unpaid Principal Balance Related Allowance (1) (Dollars in thousands) No allowance recorded: Commercial loans, excluding PPP $ 10,970 $ 19,530 $ — $ 7,996 $ 12,090 $ — Commercial real estate loans – owner occupied 6,978 7,633 — 6,507 6,784 — Commercial real estate loans – all other 1,836 1,837 — — — — Consumer loans 174 197 — 74 101 — Total $ 19,958 $ 29,197 $ — $ 14,577 $ 18,975 $ — With allowance recorded: Commercial loans, excluding PPP $ 19,958 $ 20,040 $ 2,711 $ 1,105 $ 1,122 $ 561 Total $ 19,958 $ 20,040 $ 2,711 $ 1,105 $ 1,122 $ 561 Total Commercial loans, excluding PPP $ 30,928 $ 39,570 $ 2,711 $ 9,101 $ 13,212 $ 561 Commercial real estate loans – owner occupied 6,978 7,633 — 6,507 6,784 — Commercial real estate loans – all other 1,836 1,837 — — — — Consumer loans 174 197 — 74 101 — Total $ 39,916 $ 49,237 $ 2,711 $ 15,682 $ 20,097 $ 561 (1) When the discounted cash flows, collateral value or market price equals or exceeds the recorded investment in the loan, then specific reserves are not required to be set aside for the loan within the ALLL. This typically occurs when the impaired loans have been partially charged-off and/or there have been interest payments received and applied to the balance of the principal outstanding. At December 31, 2020 and December 31, 2019, there were $20.0 million and $14.6 million, respectively, of impaired loans for which no specific reserves had been allocated because these loans, in our judgment, were sufficiently collateralized. Of the impaired loans at December 31, 2020 for which no specific reserves were allocated, $8.7 million had been deemed impaired in the prior year. Average balances and interest income recognized on impaired loans, by portfolio type, for the year ended December 31, 2020, 2019 and 2018 were as follows: Year Ended December 31, 2020 2019 2018 Average Balance Interest Income Recognized Average Balance Interest Income Recognized Average Balance Interest Income Recognized (Dollars in thousands) No allowance recorded: Commercial loans, excluding PPP $ 9,307 $ 534 $ 3,828 $ 581 $ 4,289 $ 101 Commercial real estate loans – owner occupied 5,216 53 3,038 267 856 — Commercial real estate loans – all other 367 36 — — 370 — Residential mortgage loans – single family — — — — — — Consumer loans 138 5 69 3 48 — Total 15,028 628 6,935 851 5,563 101 With allowance recorded: Commercial loans, excluding PPP $ 5,032 $ 930 $ 221 $ 53 $ 96 $ — Total $ 5,032 $ 930 $ 221 $ 53 $ 96 $ — Total Commercial loans, excluding PPP $ 14,339 $ 1,464 $ 4,049 $ 634 $ 4,385 $ 101 Commercial real estate loans – owner occupied 5,216 53 3,038 267 856 — Commercial real estate loans – all other 367 36 — — 370 — Residential mortgage loans – single family — — — — — — Consumer loans 138 5 69 3 48 — Total $ 20,060 $ 1,558 $ 7,156 $ 904 $ 5,659 $ 101 The interest that would have been earned had the impaired loans remained current in accordance with their original terms was $1.8 million in 2020, $416 thousand in 2019 and $362 thousand in 2018. Troubled Debt Restructurings Pursuant to the FASB's ASU No. 2011-2, A Creditor's Determination of whether a Restructuring is a Troubled Debt Restructuring , the Company had $6.7 million TDRs at December 31, 2020 and zero at December 31, 2019. TDRs consist of loans to which modifications have been made for the purpose of alleviating temporary impairments of the borrower's financial condition and cash flows. Those modifications have come in the forms of changes in amortization terms, reductions in interest rates, interest only payments and, in limited cases, concessions to outstanding loan balances. The modifications are made as part of workout plans we enter into with the borrower that are designed to provide a bridge for the borrower's cash flow shortfalls in the near term. If a borrower works through the near term issues, then in most cases, the original contractual terms of the borrower's loan will be reinstated. TDRs do not include short term loan modifications made on a good faith basis in response to COVID-19. The following table presents loans restructured as TDRs during the years ended December 31, 2020, 2019 and 2018: Year Ended December 31, 2020 2019 2018 Number of Pre-Modification Post-Modification Number of Pre-Modification Post-Modification Number of Pre-Modification Post-Modification (Dollars in thousands) Nonperforming Commercial loans 4 3,298 2,085 — — — — — — Commercial real estate – owner occupied 1 3,851 4,627 — — — — — — Total nonperforming 5 7,149 6,712 — — — — — — Total troubled debt restructurings (1) 5 $ 7,149 $ 6,712 — $ — $ — — $ — $ — (1) No loans were restructured during the years ended December 31, 2019 or December 31, 2018.

The weighted average percentage yields on these deposits for each of the years ended December 31, 2020 and December 31, 2019 was 0.34% and 2.22%, respectively. Interest bearing deposits with financial institutions can be withdrawn on demand and are considered cash equivalents for purposes of the consolidated statements of cash flows. At December 31, 2020 and December 31, 2019, we had $1.6 million and $2.4 million, respectively, of interest-bearing time deposits at other financial institutions, which were scheduled to mature within one year or had no stated maturity date. The weighted average percentage yields on these deposits were 1.54% and 2.04% for the years ended December 31, 2020 and December 31, 2019, respectively. Liability The aggregate amount of time deposits in denominations of $250,000 or more at December 31, 2020 and 2019 was $91.0 million and $112 million, respectively.

Leases [Abstract]
Leases	Leases We have historically entered into a number of lease arrangements under which we are the lessee. Specifically, all of our physical locations are subject to operating leases. In addition, we have elected the short-term lease practical expedient related to operating leases. Two of our office leases, including our corporate headquarters, include multiple optional renewal periods. To the extent we conclude that it is reasonably certain that a renewal option will be exercised, that renewal period is then included in the lease term, and the related payments are reflected in the ROU asset and lease liability. We did not consider any additional renewal periods to be reasonably certain of being exercised for our corporate headquarters because of the length of the lease term to renewal. All of our leases include fixed rental payments. We commonly enter into leases under which the lease payments increase at pre-determined dates. While the majority of our leases are gross leases, we also have a number of leases in which we make separate payments to the lessor based on the lessor’s property and casualty insurance costs and the property taxes assessed on the property, as well as a portion of the common area maintenance associated with the property. During the year ended December 31, 2020 and 2019, we recognized rent expense associated with our leases as follows: Year Ended December 31, 2020 2019 (Dollars in thousands) Lease cost: Operating lease cost $ 2,432 $ 2,271 Short-term lease cost (1) 144 158 Total lease cost $ 2,576 $ 2,429 Weighted-average remaining lease term—operating leases (in years) 4.37 5.37 (1) Includes leases that are less than 12 months and equipment leases that are accounted for on a cash basis. Because we generally do not have access to the rate implicit in the lease, we utilize our borrowing rate with the FHLB as the discount rate. The weighted average discount rate associated with operating leases as of December 31, 2020 and December 31, 2019 is 2.31% and 1.57%, respectively. Supplemental balance sheet information related to leases was as follows: Financial Statement Classification December 31, 2020 December 31, 2019 (Dollars in thousands) Operating right-of-use assets Other assets $ 10,002 $ 12,159 Operating lease liabilities Other liabilities $ 10,933 $ 13,020 During the year ended December 31, 2020 and 2019 , we had the following cash and non-cash activities associated with our leases: Year Ended December 31, 2020 2019 (Dollars in thousands) Cash paid for amounts included in the measurement of lease liabilities Operating cash flows from operating leases (fixed payments) $ 2,363 $ 2,031 Noncash activities: Right-of-use assets obtained in exchange for new operating lease liabilities $ — $ 12,677 Maturities of operating lease liabilities as of December 31, 2020 are as follows: Amount (Dollars in thousands) For the years ending December 31, 2021 $ 2,490 2022 2,575 2023 2,662 2024 2,750 2025 and beyond 1,020 Total 11,497 Less: Imputed interest (564) Total Lease liabilities $ 10,933

Borrowings and Contractual Obligations	Borrowings and Contractual Obligations At December 31, 2020 and 2019, our borrowings and contractual obligations consisted of the following: December 31, 2020 2019 (Dollars in thousands) FHLB advances—short-term $ 10,000 $ 30,000 Total $ 10,000 $ 30,000 The table below sets forth the amounts of, the interest rates we pay on, and the maturity dates of these FHLB borrowings. These borrowings had a weighted-average annualized interest rate of 1.62% for the year ended December 31, 2020. Principal Amounts Interest Rate Maturity Dates (Dollars in thousands) $10,000 1.62% January 25, 2021 At December 31, 2020, $434 million of loans were pledged to support our FHLB borrowings and our unfunded borrowing capacity. As of December 31, 2020, we had unused borrowing capacity of $242 million with the FHLB. The highest amount of borrowings outstanding at any month-end during the year ended December 31, 2020 was $124 million. As of December 31, 2019, we had $30.0 million of outstanding short-term borrowings and no outstanding long-term borrowings that we had obtained from the FHLB. These borrowings had a weighted-average annualized interest rate of 1.82% for the year ended December 31, 2019. As of December 31, 2019 we had unused borrowing capacity of $172 million with the FHLB. The highest amount of borrowings outstanding at any month-end during the year ended December 31, 2019 was $55 million. These FHLB borrowings were obtained in accordance with the Company’s asset/liability management objective to reduce the Company’s exposure to interest rate fluctuations and increase our contingent funding. Junior Subordinated Debentures . We formed two grantor trusts to sell and issue to institutional investors floating junior trust preferred securities ("trust preferred securities"). The net proceeds from the sales of the trust preferred securities was used in exchange for our issuance to the grantor trusts for the principal amount of our junior subordinated floating rate debentures (the "Debentures"). The payment terms of the Debentures are used by the grantor trusts to make the payments that come due to the holders of the trust preferred securities pursuant to the terms of those securities. The Debentures also were pledged by the grantor trusts as security for the payment obligations of the grantor trusts under the trust preferred securities. Set forth below are the respective principal amounts, and certain other information regarding the terms of the Debentures that remained outstanding as of December 31, 2020 and 2019: Original Issue Dates Principal Amount Interest Rate (1) Maturity Dates (Dollars in thousands) September 2002 $ 7,217 LIBOR plus 3.40% September 2032 October 2004 10,310 LIBOR plus 2.00% October 2034 Total $ 17,527 (1) Interest rate resets quarterly. These Debentures require quarterly interest payments, which are used to make quarterly distributions required to be paid on the corresponding trust preferred securities. Subject to certain conditions, we have the right, at our discretion, to defer those interest payments, and the corresponding distributions on the trust preferred securities, for up to five years. Exercise of this deferral right does not constitute a default of our obligations to pay the interest on the Debentures or the corresponding distributions that are payable on the trust preferred securities. As of December 31, 2020, we were current on all interest payments. We have committed to obtaining approval from the FRB and the CDFPI prior to making any distributions representing interest, principal or other sums on subordinated debentures or trust preferred securities. There can be no assurance that our regulators will approve such payments in the future.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Per ASC 850-10-20, a related party is defined under GAAP to include: affiliates, principal owners and their immediate family members, management and their immediate families, other parties with which the entity may deal if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests, and other parties that can significantly influence the management or operating policies of the transacting parties or that have an ownership interest in one of the transacting parties and can significantly influence the other to an extent that one or more of the transacting parties might be prevented from fully pursuing its own separate interests. GAAP requires disclosure of all material related party transactions, excluding compensation arrangements, expense allowances, and items eliminated in consolidation. Occasionally, we participate in loans with our affiliates through the ordinary course of business. These loan participations are not considered material transactions. Excluding these loan participations, the equity transactions described in Note 15, Shareholders' Equity, and the transactions noted below, we have no other related party transactions. Deposits maintained by members of the Board of Directors and executive officers at the Bank totaled $67 thousand and $93 thousand at December 31, 2020 and 2019, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The CARES Act, passed by Congress during the first quarter of 2020 in response to the outbreak of COVID-19, provides for assistance in the form of income tax related relief measures, including temporary changes to income tax laws such as the ability to carryback NOLs for a period of five years, which does not apply to our Company. Management performed an evaluation of the tax relief measures available, and determined there was no significant impact to our Company, and therefore, no tax relief provisions were applied. The components of income tax (benefit) expense from continuing operations consisted of the following for the years ended December 31: 2020 2019 2018 (Dollars in thousands) Current taxes: Federal $ 2,665 $ — $ — State 1,694 48 97 Total current taxes 4,359 48 97 Deferred taxes: Federal (77) 1,469 (6,065) State (194) 618 (4,784) Total deferred taxes (271) 2,087 (10,849) Total income tax (benefit) expense $ 4,088 $ 2,135 $ (10,752) The reasons for the differences between the statutory federal income tax rates and our effective tax rates are summarized in the following table: Year Ended December 31, 2020 2019 2018 Federal income tax based on statutory rate 21.0 % 21.0 % 21.0 % State franchise tax net of federal income tax benefit 8.6 8.6 8.6 Permanent differences 0.5 0.6 (0.3) Other 2.8 (3.8) 2.0 Valuation allowance — — (96.1) Total effective tax rate 32.9 % 26.4 % (64.8) % At December 31, 2020 and December 31, 2019, we have a net deferred tax asset of $8.5 million and $8.4 million, respectively. Adjustments to our deferred tax valuation allowance could be required in the future if we were to conclude, on the basis of our assessment of the realizability of the deferred tax asset, that the amount of that asset which is more-likely-than-not, to be available to offset or reduce future taxes has decreased. Any such decrease would result in income tax expense. The components of our net deferred tax asset are as follows at: December 31, 2020 2019 (Dollars in thousands) Deferred tax asset: Allowance for loan and lease losses $ 5,160 $ 4,025 State taxes 356 18 Deferred compensation 528 503 Litigation reserve 964 — Other accrued expenses 5 539 Charitable contributions — 161 Reserve for unfunded commitments 103 103 Tax credits — 227 Net operating loss carry forward 2,458 3,699 Stock based compensation 168 448 Unrealized losses on securities — 54 Lease liability 3,232 3,849 Total deferred tax assets 12,974 13,626 Deferred tax liabilities: Depreciation and amortization (179) (185) ROU Lease asset (2,957) (3,595) Unrealized gain on securities (148) — Other (1,188) (1,414) Total deferred tax liabilities (4,472) (5,194) Total net deferred tax asset $ 8,502 $ 8,432 During the year ended December 31, 2018, we had an income tax benefit of $10.8 million. The income tax benefit for the year ended December 31, 2018 is a result of our net income during the year and the release of our full valuation allowance of $11.1 million on our net deferred tax asset during the second quarter of 2018, discussed further below. Accounting rules specify that management must evaluate the deferred tax asset on a recurring basis to determine whether enough positive evidence exists to determine whether it is more-likely-than-not that the deferred tax asset will be available to offset or reduce future taxes. The tax code allows net operating losses incurred prior to December 31, 2017 to be carried forward for 20 years from the date of the loss, and based on its evaluation, management believes that the Company will be able to realize the deferred tax asset within the period that our net operating losses may be carried forward. Due to the hierarchy of evidence that the accounting rules specify, management determined that there continued to be enough positive evidence to support no valuation allowance on our deferred tax asset at December 31, 2018. Significant positive evidence included our three-year cumulative income position, continued improvement in asset quality, and the expectation that we will continue to have positive earnings based on nine trailing quarters of positive income and our forecast. Negative evidence included our accumulated deficit. Due to the hierarchy of evidence that the accounting rules specify, management determined that there continued to be enough positive evidence to support no valuation allowance on our deferred tax asset at December 31, 2018. During the year ended December 31, 2019, we had an income tax expense of $2.1 million. The income tax expense during the year ended December 31, 2019 is as a result of our net income during the year and an adjustment to our deferred tax asset during the fourth quarter to true up stock based compensation. The income tax benefit during the three months ended December 31, 2019 is the result of an adjustment to our deferred tax asset related to the true up of stock based compensation. The income tax expense during the year ended December 31, 2019 is primarily a result of our operating income partially offset by the adjustment made in the fourth quarter. Accounting rules specify that management must evaluate the deferred tax asset on a recurring basis to determine whether enough positive evidence exists to determine whether it is more-likely-than-not that the deferred tax asset will be available to offset or reduce future taxes. The tax code allows net operating losses incurred prior to December 31, 2017 to be carried forward for 20 years from the date of the loss, and based on its evaluation, management believes that the Company will be able to realize the deferred tax asset within the period that our net operating losses may be carried forward. Due to the hierarchy of evidence that the accounting rules specify, management determined that there continued to be enough positive evidence to support no valuation allowance on our deferred tax asset at December 31, 2019. Significant positive evidence included our three-year cumulative income position and the expectation that we will continue to have positive earnings based on twelve trailing quarters of positive income and our forecast. Negative evidence included our accumulated deficit and deterioration in asset quality. Due to the hierarchy of evidence that the accounting rules specify, management determined that there continued to be enough positive evidence to support no valuation allowance on our deferred tax asset at December 31, 2019. During the year ended December 31, 2020, we had an income tax expense of $4.1 million. The income tax expense during the year ended December 31, 2020 is as a result of our net income during the year and an adjustment to our deferred tax asset during the fourth quarter to true up stock based compensation. Accounting rules specify that management must evaluate the deferred tax asset on a recurring basis to determine whether enough positive evidence exists to determine whether it is more-likely-than-not that the deferred tax asset will be available to offset or reduce future taxes. The tax code allows net operating losses incurred prior to December 31, 2017 to be carried forward for 20 years from the date of the loss, and based on its evaluation, management believes that the Company will be able to realize the deferred tax asset within the period that our net operating losses may be carried forward. Due to the hierarchy of evidence that the accounting rules specify, management determined that there continued to be enough positive evidence to support no valuation allowance on our deferred tax asset at December 31, 2020. Significant positive evidence included our three-year cumulative income position, the expectation that we will continue to have positive earnings based on positive income in eleven of the last twelve trailing quarters, and a shift from accumulated deficit to retained earnings during the year. Negative evidence included our net loss for the first quarter of 2020 and deterioration in asset quality. Due to the hierarchy of evidence that the accounting rules specify, management determined that there continued to be enough positive evidence to support no valuation allowance on our deferred tax asset at December 31, 2020. As of December 31, 2020, we had net operating loss carryforwards of zero and $28.7 million for federal and state tax purposes, respectively, which are available to offset future taxable income. If not used, these carryforwards begin expiring in 2032 and would fully expire in 2036. Refer to the table below for the amount and expiration of our net operating loss carryforwards: Federal State Expiration (Dollars in thousands) 2010 (1) $ — $ 4,472 12/31/2032 2012 — 774 12/31/2032 2013 — 8,727 12/31/2033 2015 — 280 12/31/2035 2016 — 14,453 12/31/2036 $ — $ 28,706 (1) California net operating loss carryforwards were suspended by the Franchise Tax Board during these periods and the carryover was extended. (2) As a result of the Tax Cuts and Jobs Act, federal net operating loss carryforwards do not expire starting with any losses sustained during 2018 or later. California net operating loss carryforwards begin to expire on the date listed. We file income tax returns with the U.S. federal government and the State of California. As of December 31, 2020, we were subject to examination by the Internal Revenue Service with respect to our U.S. federal tax returns for the 2017 to 2019 tax years and the Franchise Tax Board for California state income tax returns for the 2016 to 2019 tax years. Net operating losses on our U.S. federal and California state income tax returns may be carried forward up to 20 years. In June 2020, the State of California suspended the use of net operating losses for the years 2020, 2021, and 2022, and extended the carryover periods for these years. As of December 31, 2020, we do not have any unrecognized tax benefits.

Stock-Based Employee Compensation Plans	Stock-Based Employee Compensation PlansIn May 2010, our shareholders approved the adoption of our 2010 Equity Incentive Plan, which was amended at the Annual Shareholders meeting held in May 2013 (the “2010 Incentive Plan”), and which superseded our shareholder-approved 2008 and 2004 Equity Incentive Plans (the “Previously Approved Plans”). As of December 31, 2020, there were no options to purchase shares of our common stock granted under the Previously Approved Plans. As of December 31, 2020, there were options to purchase a total of 339,587 shares of our common stock and 55,093 shares of our unvested restricted stock grants under the 2010 Incentive Plan. In May 2019, our shareholders approved the adoption of our 2019 Equity Incentive Plan (the “2019 Incentive Plan”), which authorized and set aside a total of 2,000,000 shares of our common stock for issuance on the exercise of stock options or the grant of restricted stock or other equity incentives to our officers, and other key employees and directors. There were 250,000 options to purchase shares of our common stock granted under the 2019 Incentive Plan and outstanding at December 31, 2020. Since approval of the 2019 Incentive Plan, no additional awards will be issued under the 2010 Incentive Plan, although awards outstanding under the 2010 Incentive Plan will remain outstanding and will continue to be governed by the terms of the 2010 Incentive Plan and any applicable award agreements. Under the terms of the 2019 Incentive Plan, any forfeited options or unvested restricted stock grants that had been issued under the Previously Approved Plans or the 2010 Incentive Plan will not be available for future equity incentive grants. Each restricted stock option or restricted stock unit issued under the terms of the 2019 Incentive Plan will be counted against the share limit as 2.5 shares, while each stock option or Stock Appreciation Right ("SAR") issued will be counted as one share against the share limit. As of December 31, 2020, there were outstanding options to purchase a total of 250,000 shares of our common stock, 75,000 shares of our unvested restricted stock units, and 68,072 shares of our unvested restricted stock grants under the 2019 Incentive Plan. As of December 31, 2020, there remain 1,322,255 shares available for future grants under the 2019 Incentive Plan. A stock option entitles the recipient to purchase shares of our common stock at a price per share that may not be less than 100% of the fair market value of the Company’s shares on the date the option is granted. Restricted shares may be granted at such purchase prices and on such other terms, including restrictions and Company repurchase or reacquisition rights, as are fixed by the Compensation Committee at the time rights to purchase such restricted shares are granted. SARs entitle the recipient to receive a cash payment in an amount equal to the difference between the fair market value of the Company’s shares on the date of vesting and a “base price” (which, in most cases, will be equal to the fair market value of the Company’s shares on the date the SAR is granted), subject to the right of the Company to make such payment in shares of its common stock at their then fair market value. Stock units may be payable in cash or shares of common stock, or a combination of the two. A stock unit is a bookkeeping entry representing the equivalent of one common share. Options, restricted shares, SARs, and stock units may vest immediately or in installments over various periods generally ranging up to five years, subject to the recipient’s continued employment or service or the achievement of specified performance goals, as determined by the Compensation Committee at the time it grants or awards the options, the restricted shares, the SARs or the stock units. Stock options, SARs and stock units may be granted for terms of up to 10 years after the date of grant, but will terminate sooner upon or shortly after a termination of service occurring prior to the expiration of the term of the option, SAR or stock unit. The Company will become entitled to repurchase any unvested restricted shares, at the same price that was paid for the shares by the recipient, or to cancel those shares in the event of a termination of employment or service of the holder of such shares or if any performance goals specified in the award are not satisfied. To date, the Company has not granted any SARs. Under FASB ASC 718-10, we are required to recognize, in our financial statements, the fair value of the options, restricted shares, SARs and stock units that we grant as compensation cost over their respective service periods. The fair values of the options that were outstanding at December 31, 2020 under the 2010 Incentive Plan and the 2019 Incentive Plan were estimated as of their respective dates of grant using the Black-Scholes option-pricing model. The Company, under the 2010 Incentive Plan and the 2019 Incentive Plan, has also granted restricted stock and stock units for the benefit of its employees and directors. These restricted shares vest over a period ranging from three one Stock Options The table below summarizes the weighted average assumptions used to determine the fair values of the options granted during the following periods: Year Ended December 31, Assumptions with respect to: 2020 2019 2018 Expected volatility — % 28 % 30 % Risk-free interest rate — % 1.35 % 2.69 % Expected dividends — % — % — % Expected term (years) 0.0 5.1 5.8 Weighted average fair value of options granted during period $ — $ 1.99 $ 2.81 The following table summarizes the stock option activity under the Company’s equity incentive plans during the years ended December 31, 2020, 2019 and 2018, respectively.

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans The Company has a 401(k) plan that covers substantially all full-time employees. That plan permits voluntary contributions by employees, a portion of which are sometimes matched by the Company. The Company’s expenses relating to its contributions to the 401(k) plan for the years ended December 31, 2020, 2019 and 2018 were $363 thousand, $411 thousand, and $365 thousand, respectively. In January 2001, the Company established an unfunded Supplemental Retirement Plan (“SERP”) for our former CEO who retired from that position in April 2013. The SERP was amended and restated in April 2006 to comply with the requirements of new Section 409A of Internal Revenue Code. The SERP provides for 180 equal successive monthly retirement payments, each in an amount equal to 60% of the average monthly base salary during the three years immediately preceding reaching 65 years old (the “Monthly SERP Benefit”), subject to meeting certain vesting requirements. These monthly benefit payments commenced on February 1, 2013. The Company follows FASB ASC 715-30-35, which requires us to recognize in our balance sheet the funded status of any post-retirement plans that we maintain and to recognize, in other comprehensive income, changes in funded status of any such plans in any year in which changes occur. The changes in the projected benefit obligations under the SERP during 2020, 2019 and 2018, its funded status at December 31, 2020, 2019 and 2018, and the amounts recognized in our consolidated statements of financial condition at each of those dates were as follows: At December 31, 2020 2019 2018 (Dollars in thousands) Change in benefit obligation: Benefit obligation at beginning of period $ 1,982 $ 2,169 $ 2,345 Service cost — — — Interest cost 110 120 131 Actuarial loss/(gain) — — — (Benefits paid) (307) (307) (307) Benefit obligation at end of period $ 1,785 $ 1,982 $ 2,169 Funded status: Amounts recognized in the Statement of Financial Condition Unfunded accrued SERP liability—current $ (299) $ (299) $ (299) Unfunded accrued SERP liability—noncurrent (1,486) (1,683) (1,870) Total unfunded accrued SERP liability $ (1,785) $ (1,982) $ (2,169) Net amount recognized in accumulated other comprehensive income Prior service cost/(benefit) $ — $ — $ — Net actuarial loss/(gain) — — — Total net amount recognized in accumulated other comprehensive income $ — $ — $ — Accumulated benefit obligation $ 1,785 $ 1,982 $ 2,169 Components of net periodic SERP cost year to date: Service cost $ — $ — $ — Interest cost 110 120 131 Amortization of prior service cost/(benefit) — — — Amortization of net actuarial loss/(gain) — — — Net periodic SERP cost $ 110 $ 120 $ 131

Earnings Per Share [Abstract]
Earnings Per Share ("EPS")	Earnings Per Share (“EPS”) Basic EPS excludes dilution and is computed by dividing net income or loss allocable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if stock options or other contracts to issue common stock were exercised or converted into common stock that would then share in our earnings. The following table shows how we computed basic and diluted EPS for the year ended December 31, 2020, 2019, and 2018. For the Year Ended December 31, 2020 2019 2018 (Dollars and amounts in thousands, except per share data) Basic EPS: Net income (loss) $ 8,334 $ 5,680 $ 27,339 Less dividends on preferred stock — — — Less dividends on common stock — — — Less dividends on unvested shares — — — Net income allocable to common shareholders $ 8,334 $ 5,680 $ 27,339 Less earnings allocated to participating securities 72 166 648 Earnings allocated to common shareholders $ 8,262 $ 5,514 $ 26,691 Weighted average common shares outstanding 23,507 22,811 22,788 Basic earnings per common share $ 0.35 $ 0.24 $ 1.17 Diluted EPS: Earnings allocated to common shareholders $ 8,334 $ 5,680 $ 27,339 Weighted average common shares outstanding 23,507 22,811 22,788 Add dilutive effects of restricted stock grants 115 149 115 Add dilutive effects of restricted stock units 91 — — Add dilutive effects for assumed conversion of Series A preferred stock — 539 438 Add dilutive effects for stock options 3 133 186 Weighted average diluted common shares outstanding 23,716 23,632 23,527 Diluted earnings per common share $ 0.35 $ 0.24 $ 1.16 (1) The basic and diluted earnings per share amounts for the years ended December 31, 2020, 2019 and 2018 are the same under both the Treasury Stock Method and the Two-Class Method as prescribed in FASB ASC 260-10, Earnings Per Share . The weighted average shares that have an antidilutive effect in the calculation of diluted net income (loss) per share and have been excluded from the computations above were as follows: For the Year Ended December 31, 2020 2019 2018 Stock options (1) 672,827 265,093 138,608 (1) Stock options were excluded from the computation of diluted earnings per common share for the years ended December 31, 2020, 2019 and 2018 because the options were either “out-of-the-money” or the effect of exercise would have been antidilutive.

Shareholders' Equity

Shareholders' Equity	12 Months Ended

Equity [Abstract]
Shareholders' Equity	Shareholders’ Equity Preferred Stock At December 31, 2020 and 2019 we did not have any shares of preferred stock outstanding. Effective as of the close of business on May 15, 2019, the Company filed an amendment to the Articles of Incorporation to authorize a class of Non-Voting Common Stock after obtaining shareholder approval on that same date. As a result, each share of the then outstanding Series A Non-Voting Preferred Stock was automatically converted into one share of Non-Voting Common Stock as of the effective date. The Non-Voting Common Stock has the same relative rights as, and is identical in all respects with, each other share of Common Stock of the Company, except that holders of Non-Voting Common Stock are not entitled to vote on any matter other than where required under California law. During the year ended December 31, 2018, Carpenter Community BancFund, LP and Carpenter Community BancFund-A, LP ("the Carpenter Funds"), the largest shareholders of PMBC, the holding company of the Bank, sold all of their equity interest in PMBC to certain accredited investors in privately negotiated transactions (the "Carpenter Disposition Transactions"). The Carpenter Disposition Transactions included the sale of 1,467,155 shares of a new series of non-voting preferred stock designated as Series A Non-Voting Preferred Stock (the Series A Non-Voting Preferred Stock) that PMBC issued to the Carpenter Funds in exchange (the Exchange) for 1,467,155 shares of PMBC’s common stock owned by the Carpenter Funds. At the time of and after giving effect to the Exchange, PMBC had 21,917,995 shares of common stock issued and outstanding and 1,467,155 shares of Series A Non-Voting Preferred Stock issued and outstanding. The shares of Series A Non-Voting Preferred Stock were issued to the Carpenter Funds to facilitate the Carpenter Disposition Transactions with substantially the same rights, preferences and privileges of the common stock, except that the Series A Non-Voting Preferred Stock is not entitled to vote on any matter other than where required under California law and that each share of Series A Non-Voting Preferred Stock has a liquidation preference of $0.0001 per share over the common stock. The shares of common stock and Series A Non-Voting Preferred Stock purchased by investors from the Carpenter Funds in the Carpenter Disposition Transactions were at the time of the transaction restricted securities subject to trading restrictions under the federal securities laws. The lead investor in the Carpenter Disposition Transactions, Patriot Financial Partners III, L.P., a Delaware limited partnership ("Patriot"), acquired 3,636,363 total common-equivalent shares of PMBC, comprised of 2,169,208 shares of common stock (9.9% of the total voting shares outstanding after giving effect to the Exchange) and 1,467,155 shares of the Series A Non-Voting Preferred Stock. At the time of and after giving effect to the Carpenter Disposition Transactions (including the Exchange), Patriot held a 15.6% equity interest in the PMBC. Accumulated Other Comprehensive Income, net Accumulated other comprehensive income, net as of December 31, 2020, 2019 and 2018 was as follows: Unrealized Gain (Loss) on Securities Available-for-Sale, net of tax Accumulated Other Comprehensive Income, Net (Dollars in thousands) Beginning balance as of January 1, 2018 $ (1,143) $ (1,143) Other comprehensive income before reclassifications, net of tax of $142 thousand (50) (50) Amounts reclassified from accumulated other comprehensive loss (1) 49 49 Other comprehensive loss, net of tax of $142 thousand (1) (1) Ending balance as of December 31, 2018 $ (1,144) $ (1,144) Other comprehensive loss, net of tax of $62 thousand 577 577 Ending balance as of December 31, 2019 $ (567) $ (567) Other comprehensive loss, net of tax of $202 thousand 483 483 Ending balance as of December 31, 2020 $ (84) $ (84) (1) This balance consists of the $48 thousand net gain on sale of available for sale debt securities included in our consolidated statement of operations offset by $97 thousand included in our consolidated statement of shareholders' equity as an adjustment to our beginning retained earnings. Dividends Payment of Cash Dividends by the Company . California laws place restrictions on the ability of California corporations to pay cash dividends on preferred or common stock. Subject to certain limited exceptions, a California corporation may pay cash dividends only to the extent of (i) the amount of its retained earnings or (ii) the amount by which the fair value of the corporation’s assets exceeds its liabilities. We have committed to obtaining approval from the FRB and the CDFPI prior to paying any dividends. The Company's ability to pay dividends is also limited by the ability of the Bank to pay cash dividends to the Company. See “ —Payment of Dividends by the Bank to the Compan y” below. Payment of Dividends by the Bank to the Company . Generally, the principal source of cash available to a bank holding company consists of cash dividends from its bank subsidiaries. Under California law, the Board of Directors of the Bank may declare and pay cash dividends to the Company, which is its sole shareholder, subject to the restriction that the amount available for the payment of cash dividends may not exceed the lesser of (i) the Bank’s retained earnings or (ii) its net income for its last three fiscal years (less the amount of any dividends paid during such period). Cash dividends by the Bank to the Company in excess of that amount may be made only with the prior approval of the California Commissioner of Financial Institutions (“Commissioner”). If the Commissioner finds that the shareholders’ equity of the Bank is not adequate, or that the payment by the Bank of cash dividends to the Company would be unsafe or unsound for the Bank, the Commissioner can order the Bank not to pay such dividends.

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments To meet the financing needs of our clients in the normal course of business, we are a party to financial instruments with off-balance sheet risk. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated financial statements. At December 31, 2020 and 2019, we were committed to fund certain loans including letters of credit amounting to approximately $347 million and $316 million, respectively. The contractual amounts of a credit-related financial instrument, such as a commitment to extend credit, a credit-card arrangement or a letter of credit, represents the amount of potential accounting loss should the commitment be fully drawn upon, the client were to default, and the value of any existing collateral securing the client’s payment obligation becomes worthless. The loss reserve for unfunded loan commitments was $350 thousand and $350 thousand at December 31, 2020 and 2019, respectively. As a result, we use the same credit policies in making commitments to extend credit and conditional obligations as we do for on-balance sheet instruments. Commitments generally have fixed expiration dates; however, since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. We evaluate each client’s creditworthiness on a case-by-case basis, using the same credit underwriting standards that are employed in making commercial loans. The amount of collateral obtained, if any, upon an extension of credit is based on our evaluation of the creditworthiness of the client. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, residential real estate and income-producing commercial properties. We are required to purchase stock in the FRBSF in an amount equal to 6% of our capital, one-half of which must be paid currently with the balance due upon request. The Bank is a member of the FHLB and therefore, is required to purchase FHLB stock in an amount equal to the lesser of 1% of the Bank’s real estate loans that are secured by residential properties, or 5% of total advances. Litigation, Claims and Assessments We are a defendant in or a party to a number of legal actions or proceedings that arise in the ordinary course of business. In some of these actions and proceedings, claims for monetary damages are asserted against us. In accordance with applicable accounting guidance, we establish an accrued liability for lawsuits or other legal proceedings when they present loss contingencies that are both probable and estimable. We estimate any potential loss based upon currently available information and significant judgments and a variety of assumptions, and known and unknown uncertainties. Moreover, the facts and circumstances on which such estimates are based will change over time. Therefore, the amount of any losses we might incur in any lawsuits or other legal proceedings may exceed amounts which we had accrued based on our estimates and those estimates do not represent the maximum loss exposure that we may have in connection with any lawsuits or other legal proceedings. Based on our evaluation of the remaining lawsuits and other proceedings that were pending against us as of December 31, 2020, the outcomes in those suits or other proceedings are not expected to have, either individually or in the aggregate, a material adverse effect on our consolidated financial position, results of operations or cash flows. However, in light of the inherent uncertainties involved, some of which are beyond our control, and the very large or indeterminate damages often sought in such legal actions or proceedings, an adverse outcome in one or more of these suits or proceedings could be material to our results of operations or cash flows for any particular reporting period. Risks and Uncertainties The outbreak of the novel coronavirus (“COVID-19”) and the Federal Reserve's response to the economic challenges during the year 2020 has resulted in an uncertain and rapidly evolving economy. Governmental response to combat this pandemic have resulted in approximately 25% of our staff to shift to work remotely. Our business continuity plans have been activated by COVID-19 and we have been able to fully support our remote workforce and have the ability to support all employees in a remote work environment. These remote work arrangements have not adversely impacted our ability to serve our clients, and have not had an impact on our financial reporting systems or the internal controls we have over financial reporting, disclosures and related procedures. The most significant impact of COVID-19 on our business has been to the quality of our loan portfolio and to net interest income as short-term interest rates sharply declined. We have increased the qualitative factors used in the determination of the adequacy of our allowance for loan and lease loss in anticipation of the impact that COVID-19 will have on our clients and their ability to fulfill their obligations. We have no certainty that the provisions we made during the year will be sufficient to absorb the losses that stem from the impact of COVID-19 on our clients. As the longer term effects on our clients from the COVID-19 pandemic become more apparent, we may need to charge-off some or all of the balance on certain loans and make further provisions to increase our allowance for loan and lease losses. These potential additional provisions for loan and lease losses will have a direct impact upon our capital, including the potential need to reevaluate the need for a valuation allowance on our deferred tax asset. At this time, we don't expect that there would be any material impairment to the valuation of other long-lived assets, right of use assets, or our investment securities. The Bank is currently Well Capitalized under federal banking regulations that apply to all United States-based banks, with approximately $68 million of capital in excess of what is required for the Bank to be Well Capitalized using the ratio of Total Capital to Risk Weighted Assets. The Company has approximately $10 million of capital that it could contribute to the Bank should it be needed. In the event that future loan and leases loss and/or tax provisions reduce our capital surplus, we would be required to undertake measures to return the Bank's capital ratios to Well Capitalized levels, which could include but not be limited to raising additional capital or reducing the Bank's asset size. We believe that we would have access to equity and debt markets to secure additional capital for the Bank should the need arise, but we have no certainty regarding the extent of the availability of these markets at the time such need would arise. Increased demand for liquidity by our clients is another impact that we anticipate could occur should the COVID-19 effects be prolonged. As of December 31, 2020 the Company and the Bank's on-balance sheet liquidity was very strong and combined with our contingent liquidity resources, we believe that the Bank has sufficient resources to meet the liquidity needs of our clients. In response to COVID-19, the Federal Reserve has made other provisions that could assist the Bank in satisfying its liquidity needs, such as reducing our reserve requirement to zero, expanding access to the discount window through collateral pledging and extension of term borrowings.

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Capital/Operating Plans	Capital/Operating Plans Under federal banking regulations that apply to all United States-based bank holding companies over $3 billion in total assets and all federally insured banks, the Bank (on a stand-alone basis) must meet specific capital adequacy requirements that, for the most part, involve quantitative measures, primarily in terms of the ratios of their capital to their assets, liabilities, and certain off-balance sheet items, calculated under regulatory accounting practices. The Company (on a consolidated basis) is below the reporting threshold of $3 billion in total assets and therefore is not subject to the same capital adequacy requirements. Under those regulations, each federally insured bank is determined by its primary federal bank regulatory agency to come within one of the following capital adequacy categories on the basis of its capital ratios: • well-capitalized • adequately capitalized • undercapitalized • significantly undercapitalized; or • critically undercapitalized Certain qualitative assessments also are made by a banking institution’s primary federal regulatory agency that could lead the agency to determine that the banking institution should be assigned to a lower capital category than the one indicated by the quantitative measures used to assess the institution’s capital adequacy. At each successive lower capital category, a banking institution is subject to greater operating restrictions and increased regulatory supervision by its federal bank regulatory agency. The actual capital amounts and ratios of the Bank at December 31, 2020 and December 31, 2019 are presented in the following tables: Applicable Federal Regulatory Requirement At December 31, 2020 Actual Capital For Capital Adequacy Purposes To be Categorized As Well Capitalized Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) Total Capital to Risk Weighted Assets: Bank $ 183,698 15.8 % $ 136,864 At least 8.625% $ 116,161 At least 10.0% Common Equity Tier 1 Capital to Risk Weighted Assets: Bank $ 169,138 14.6 % $ 59,532 At least 5.125% $ 75,504 At least 6.5% Tier 1 Capital to Risk Weighted Assets: Bank $ 169,138 14.6 % $ 76,956 At least 6.625% $ 92,929 At least 8.0% Tier 1 Capital to Average Assets: Bank $ 169,138 10.7 % $ 63,473 At least 4.0% $ 79,341 At least 5.0 Applicable Federal Regulatory Requirement At December 31, 2019 Actual Capital For Capital Adequacy To be Categorized Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) Total Capital to Risk Weighted Assets: Bank $ 171,613 13.8 % $ 123,451 At least 8.625% $ 123,938 At least 10.0% Common Equity Tier 1 Capital to Risk Weighted Assets: Bank $ 157,652 12.7 % $ 63,518 At least 5.125% $ 80,560 At least 6.5% Tier 1 Capital to Risk Weighted Assets: Bank $ 157,652 12.7 % $ 82,109 At least 6.625% $ 99,151 At least 8.0% Tier 1 Capital to Average Assets: Bank $ 157,652 11.0 % $ 57,253 At least 4.0% $ 71,566 At least 5.0% As the above tables indicate, at December 31, 2020 and 2019, the Bank (on a stand-alone basis) qualified as a “well—capitalized” institution under federally mandated capital standards and federally established prompt corrective action regulations. Since December 31, 2020, there have been no events or circumstances known to us which have changed or which are expected to result in a change in the Bank’s classification as a well-capitalized institution. In early July 2013, the Federal Reserve Board and the FDIC issued final rules implementing the Basel III regulatory capital framework and related Dodd-Frank Wall Street Reform and Consumer Protection Act changes. The rules revise minimum capital requirements and adjust prompt corrective action thresholds. The final rules revise the regulatory capital elements, add a new common equity Tier 1 capital ratio, increase the minimum Tier 1 capital ratio requirement, and implement a new capital conservation buffer. The rules also permit certain banking organizations to retain, through a one-time election, the existing treatment for accumulated other comprehensive income. The final rules took effect for community banks on January 1, 2015, subject to a transition period for certain parts of the rules. At December 31, 2020, the Bank (on a stand-alone basis) continued to qualify as a well-capitalized institution under the capital adequacy guidelines described above.

Segment Reporting [Abstract]
Business Segment Information	Business Segment Information We have one reportable business segment, commercial banking. The commercial banking segment provides middle-market businesses, professional firms and individuals with a diversified range of products and services such as various types of deposit accounts, various types of commercial and consumer loans, cash management services, and online banking services. Since our operating segment derives all of its revenues from interest and noninterest income and interest expense constitutes its most significant expense, this segment is reported below using net interest income (interest income less interest expense) and noninterest income (primarily net gains on sales of Small Business Administration loans and fee income). We do not allocate general and administrative expenses or income taxes to our operating segment. The following table sets forth information regarding the net interest income (expense) and noninterest income for our commercial banking and other segments, respectively, for the years ended December 31, 2020, 2019 and 2018.

Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Accounting	The accompanying consolidated financial statements have been prepared in accordance with the instructions of the U.S. Securities and Exchange Commission (the “SEC”) to Form 10-K and in accordance with generally accepted accounting principles in effect in the United States (“GAAP”), on a basis consistent with prior periods.
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with GAAP requires us to make certain estimates and assumptions that could affect the reported amounts of certain of our assets, liabilities, and contingencies at the date of the financial statements and the reported amounts of our revenues and expenses during the reporting periods. Material estimates that are particularly susceptible to changes in the near term relate primarily to our determinations of the allowance for loan and lease losses (“ALLL”), the fair values of securities available for sale, and the determination of a valuation allowance pertaining to deferred tax assets. If circumstances or financial trends on which those estimates were based were to change in the future or there were to occur any currently unanticipated events affecting the amounts of those estimates, our future financial position or results of operations could differ, possibly materially, from those expected at the current time.
Principles of Consolidation	Principles of ConsolidationOur consolidated financial statements for the years ended December 31, 2020, 2019 and 2018 include the accounts of PMBC, the Bank and PMAR. All significant intercompany balances and transactions were eliminated in consolidation.
Cash and Cash Equivalents	Cash and Cash EquivalentsFor purposes of the statements of cash flow, cash and cash equivalents consist of cash and due from banks, interest bearing demand deposits with the FRBSF, federal funds sold and interest-bearing deposits, with original maturities of 90 days or less, with financial institutions. Generally, federal funds are sold for one-day periods.
Federal Home Loan Bank Stock and Federal Reserve Bank Stock	Federal Home Loan Bank Stock and Federal Reserve Bank Stock The Bank, as a member of the Federal Home Loan Bank System, is required to maintain an investment in capital stock of the Federal Home Loan Bank of San Francisco (“FHLB”) in varying amounts based on asset size and on amounts borrowed from the FHLB. Because no ready market exists and there is no quoted market value for this stock, the Bank’s investment in this stock is carried at cost. The Bank also maintains an investment in capital stock of the FRBSF, which is carried at cost because no ready market exists and there is no quoted market value for this stock.
Securities Available for Sale, at Fair Value	Securities Available for Sale, at Fair Value Securities available for sale are those which we intend to hold for an indefinite period of time, but which may be sold in response to changes in liquidity needs, changes in interest rates, changes in prepayment risks and other similar factors. These securities are recorded at fair value, with unrealized gains and losses excluded from earnings and reported as other comprehensive income or loss, net of taxes. Purchased premiums and discounts are recognized as interest income using the interest method over the term of these securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. Declines in the fair value of these securities below their cost which are other-than-temporary are reflected in earnings as realized losses. In determining other-than-temporary losses, we consider a number of factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether we have the intent to sell the security or it is more likely than not that we will be required to sell the security before its anticipated recovery. A high degree of subjectivity and judgment is involved in assessing whether an other-than-temporary decline exists and such assessments are based on information available to us at the time we make such assessments. We recognize other-than-temporary impairments (“OTTI”) to our available-for-sale debt securities in accordance with FASB ASC 320-10. When there are credit losses associated with, but we have no intention to sell, an impaired debt security, and it is more likely than not that we will not have to sell the security before recovery of its cost basis, we will separate the amount of impairment, or OTTI, between the amount that is credit-related and the amount that is related to non-credit factors. Credit-related impairments are recognized in our consolidated statements of operations. Any non-credit-related impairments are recognized and reflected in other comprehensive income in our consolidated statements of financial condition.
Loans and Allowance for Loan and Lease Losses	Loans and Allowance for Loan and Lease Losses Loans that we intend and have the ability to hold for the foreseeable future or until maturity or pay-off are stated at their respective principal amounts outstanding, net of unearned income. Interest is accrued daily as earned, except where reasonable doubt exists as to collectability of the loan. A loan with principal or interest that is 90 days or more past due, based on its contractual payment due dates, is placed on nonaccrual status, in which case accrual of interest is discontinued, except that we may elect to continue the accrual of interest when the estimated net realizable value of collateral securing the loan is expected to be sufficient to enable us to recover both principal and accrued interest and those loans are in the process of collection. Generally, interest payments received on nonaccrual loans are applied to principal. Once all principal has been received by us, any additional interest payments are recognized as interest income on a cash basis. An ALLL is established by means of a provision for loan and lease losses that is charged against income. If we conclude that the collection, in full, of the carrying amount of a loan has become unlikely, the loan, or the portion thereof that is believed to be uncollectible, is charged against the ALLL. We carefully monitor changing economic conditions, the loan portfolio by category, the financial condition of borrowers and the history of the performance of the loan portfolio in determining the adequacy of the ALLL. Additionally, as the volume of loans increases, additional provisions for loan losses may be required to maintain the allowance at levels deemed adequate. Moreover, if economic conditions were to deteriorate, causing the risk of loan losses to increase, it would become necessary to increase the allowance to an even greater extent, which would necessitate additional provisions that would be charged to income. We also evaluate the unfunded portion of loan commitments and establish a loss reserve, included in other liabilities, for such unfunded commitments through a charge against noninterest expense. The loss reserve for unfunded loan commitments was $350,000 at December 31, 2020 and 2019. The ALLL is based on estimates, and ultimate loan losses may vary from current estimates. These estimates are reviewed periodically and, as adjustments become necessary, they are recorded in earnings in the periods in which they become known.
Impaired Loans	Impaired Loans A loan is generally classified as impaired when, in management’s opinion, the principal or interest will not be collectible in accordance with its contractual terms. We measure and reserve for impairment on a loan-by-loan basis using
Restructured Loans	Restructured Loans We sometimes modify or restructure loans when the borrower is experiencing financial difficulties by making a concession to the borrower in the form of changes in the amortization terms, reductions in the interest rates, the acceptance of interest only payments and, in limited cases, concessions to the outstanding loan balances. These loans are classified as troubled debt restructurings (“TDRs”) and considered impaired loans. TDRs are loans modified for the purpose of alleviating temporary impairments to the borrower’s financial condition or cash flows. A workout plan between us and the borrower is designed to provide a bridge for borrower cash flow shortfalls in the near term. A TDR loan may be returned to accrual status when the loan is brought current, has performed in accordance with the contractual restructured terms for a time frame of at least six months and the ultimate collectability of the total contractual restructured principal and interest in no longer in doubt. These loans, while no longer considered a TDR, are still considered impaired loans.
Loan Origination Fees and Costs	Loan Origination Fees and Costs Loan origination fees and related direct costs for loans held for investment are deferred and amortized to interest income as an adjustment to yield over the respective lives of the loans using the effective interest method, except for loans that are revolving or short-term in nature for which the straight line method is used, which approximates the interest method.
Investment in Unconsolidated Subsidiaries	Investment in Unconsolidated SubsidiariesInvestment in unconsolidated subsidiaries is stated at cost.
Other Real Estate Owned	Other Real Estate Owned Other real estate owned (“OREO”) consists of real properties acquired by us through foreclosure or in lieu of foreclosure in satisfaction of loans. OREO is recorded at fair value less estimated selling costs at the time of acquisition or foreclosure. Loan balances in excess of fair value, less selling costs, are charged to the ALLL prior to foreclosure. Any subsequent operating expenses or income, reductions in estimated fair values and gains or losses on disposition of such properties are charged or credited to current operations.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation and amortization which are charged to expense on a straight-line basis over the estimated useful lives of the assets or, in the case of leasehold improvements, over the term of the leases, whichever is shorter. For income tax purposes, accelerated depreciation methods are used. Maintenance and repairs are charged directly to expense as incurred. Improvements to premises and equipment that extend their useful lives are capitalized. When such an asset is disposed of, the applicable costs and accumulated depreciation thereon are removed from the accounts and any resulting gain or loss is included in current operations. Rates of depreciation and amortization are based on the following estimated useful lives: Furniture and equipment Three Leasehold improvements Lesser of the lease term or estimated useful life
Income Taxes	Income Taxes Deferred income taxes and liabilities are determined using the asset and liability method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax basis of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. We record as a deferred tax asset on our balance sheet an amount equal to the tax credit and tax loss carryforwards and tax deductions ("tax benefits") that we believe will be available to us to offset or reduce the amount of our income taxes in future periods. Under applicable federal and state income tax laws and regulations, such tax benefits will expire if not used within specified periods of time. Accordingly, the ability to fully use our deferred tax asset depends on the amount of taxable income that we generate during those time periods. At least once each year, or more frequently, if warranted, we make estimates of future taxable income that we believe we are likely to generate during those future periods. If we conclude, on the basis of those estimates and the amount of the tax benefits available to us, that it is more likely than not that we will be able to fully utilize those tax benefits prior to their expiration, we recognize the deferred tax asset in full on our balance sheet. On the other hand, if we conclude on the basis of those estimates and the amount of the tax benefits available to us that it has become more likely than not that we will be unable to utilize those tax benefits in full prior to their expiration, then, we would establish (or increase any existing) valuation allowance to reduce the deferred tax asset on our balance sheet to the amount which we believe we are more likely than not to be able to utilize. Such a reduction is implemented by recognizing a non-cash charge that would have the effect of increasing the provision, or reducing any credit, for income taxes that we would otherwise have recorded in our statement of operations. The determination of whether and the extent to which we will be able to utilize our deferred tax asset involves significant management judgments and assumptions that are subject to period to period changes as a result of changes in tax laws, changes in market or economic conditions that could affect our operating results or variances between our actual operating results and our projected operating results, as well as other factors. Uncertain tax positions that meet the more likely than not recognition threshold are measured to determine the amount of benefit to recognize. An uncertain tax position is measured at the largest amount of benefit that management believes has a greater than 50% likelihood of realization upon settlement.
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic income (loss) per share for any fiscal period is computed by dividing net income (loss) allocable to our common shareholders for such period by the weighted average number of common shares outstanding during that period. Fully diluted income (loss) per share reflects the potential dilution that could have occurred assuming the conversion of any convertible securities into common stock at conversion prices, and the exercise of all outstanding options and warrants to purchase shares of our common stock at exercise prices, that were less than the market price of our shares, thereby increasing the number of shares outstanding during the period, and is determined using the treasury method. Although accumulated undeclared dividends on our preferred stock are not recorded in the accompanying consolidated statement of operations, such dividends are included for purposes of computing earnings (loss) per share available to our common shareholders.
Stock Option Plans	Stock Option Plans We follow Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 718-10, Share-Based Payment
Comprehensive Income (Loss)	Comprehensive Income (Loss)Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. However, certain changes in assets and liabilities, such as unrealized gains and losses on securities available for sale, are reported as a separate component of the equity in the accompanying consolidated statement of financial condition, net of income taxes, and such items, along with net income, are components of comprehensive income (loss).
Segment Reporting	Segment ReportingDuring the years ended December 31, 2020, 2019 and 2018, we had one reportable segment, which was our commercial banking division, and one non-reportable segment which was our discontinued operations related to our mortgage banking division. In connection with our exit from the mortgage banking business in 2013, the revenues and expenses of our mortgage banking division have been classified as discontinued operations for all periods presented.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which requires the measurement of all expected credit losses for financial assets held at the reporting date, based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions will now use forward-looking information to better inform their credit loss estimates. Additionally, the ASU amends the accounting guidance for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. On November 15, 2019, the FASB issued ASU 2019-10, " Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates " which finalizes various effective date delays for private companies, not-for-profit organizations, and smaller reporting companies applying the credit losses (CECL), leases, and hedging standards. The effective date for smaller reporting companies has been delayed from the interim and annual periods beginning after December 15, 2020 to the interim and annual periods beginning after December 15, 2022. Early adoption is permitted for interim and annual periods beginning after December 15, 2018. Upon issuance of the final ASU, we plan to adopt this guidance on January 1, 2023 and expect that it will have a material impact on the determination of our ALLL. We are unable to estimate the expected impact to the ALLL upon adoption due to various factors, primarily the fine tuning of our qualitative assumptions used within our preliminary model, uncertainty regarding economic conditions and the size and mix of our loan portfolio at the time of adoption, which could impact our historical loss factors. We are currently working with our existing ALLL software provider on further developing the model to perform the ALLL calculations upon adoption and we believe that we currently have in place the internal team capable of handling this implementation. In December 2019, the FASB issued ASU 2019-12, " Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes," which eliminates certain exceptions to the guidance in ASC 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance is effective for public business entities for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years. We adopted this guidance on January 1, 2021, and do not expect any material impact related to this pronouncement. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which provides temporary optional expedients to ease the financial reporting burdens of the expected market transition from London Interbank Offered Rate (LIBOR) to an alternative reference rate such as Secured Overnight Financing Rate (SOFR). The guidance was effective upon issuance and generally can be applied through December 31, 2022. We are currently evaluating this guidance to determine the date of adoption and the impact on the Company. In October 2020, the FASB issue ASU 2020-08, "Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs,"
Subsequent Events	Subsequent Events Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. The Company recognizes in the financial statements the effects of all subsequent events that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing the financial statements. The Company’s financial statements do not recognize subsequent events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after the balance sheet date and before financial statements are available to be issued. The Company has evaluated events subsequent to the balance sheet date through the date these consolidated financial statements were filed with the SEC.
Fair Value Measurement	Under FASB ASC 820-10, we group assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: Level 1 Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2 Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. Risks with Fair Value Measurements Fair value estimates are made at a discrete point in time based on relevant market information and other information about the financial instruments. Because no active market exists for a significant portion of our financial instruments, fair value estimates are based in large part on judgments we make primarily regarding current economic conditions, risk characteristics of various financial instruments, prepayment rates, and future expected loss experience. These estimates are subjective in nature and invariably involve some inherent uncertainties. Additionally, the occurrence of unexpected events or changes in circumstances can occur that could require us to make changes to our assumptions and which, in turn, could significantly affect and require us to make changes to our previous estimates of fair value. In addition, the fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of existing and anticipated future client relationships and the value of assets and liabilities that are not considered financial instruments, such as premises and equipment and OREO. Measurement Methodology Cash and Cash Equivalents. The fair value of cash and cash equivalents approximates its carrying value. Interest-Bearing Deposits with Financial Institutions. The fair values of interest-bearing deposits maturing within one year approximate their carrying values. FHLB and FRBSF Stock. The Bank is a member of the Federal Home Loan Bank of San Francisco (“FHLB”) and the FRBSF. As members, we are required to own stock of the FHLB and the FRBSF, the amount of which is based primarily on the level of our borrowings from those institutions. We also have the right to acquire additional shares of stock in either or both of the FHLB and the FRBSF. During the year ended December 31, 2020, we purchased no FHLB or FRBSF stock. No shares of FHLB or FRBSF stock were called during the year ended December 31, 2020. During the year ended December 31, 2019, we purchased no FHLB or FRBSF stock. No shares of FHLB stock or FRBSF stock were called during the year ended December 31, 2019. The fair values of the FHLB and FRBSF stock are equal to their respective carrying amounts, are classified as restricted securities and are periodically evaluated for impairment based on our assessment of the ultimate recoverability of our investments in that stock. Any cash or stock dividends paid to us on such stock are reported as income. Investment Securities Available for Sale. Fair value measurement for our investment securities available for sale is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 investment securities include those traded on an active exchange, such as the New York Stock Exchange, and U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets. Level 2 investment securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. Securities classified as Level 3 include asset-backed securities in less liquid markets. Equity Investments Without Readily Determinable Fair Value . Equity investments without readily determinable fair value are accounted for under the measurement alternative method of accounting. These investments are measured at cost, less any impairment, plus or minus any changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Any cash or stock dividends paid to us on such investments are reported as noninterest income. Impaired Loans . Loans measured for impairment are measured at an observable market price (if available), or the fair value of the loan’s collateral (if the loan is collateral dependent). The fair value of an impaired loan may be estimated using one of several methods, including collateral value, market value of similar debt, liquidation value and discounted cash flows. Those impaired loans not requiring a specific loan loss reserve represent loans for which the fair value of the expected repayments or collateral exceeds the recorded investments in such loans. When the fair value of the collateral is based on an observable market price or a current appraised value, we record the impaired loan at Level 2. When an appraised value is not available or we determine that the fair value of the collateral is further impaired below the appraised value and there is no observable market price, we record the impaired loan at Level 3. Loans . The fair value for loans with variable interest rates less a credit discount is the carrying amount. The fair value of fixed rate loans is derived by calculating the present value of expected future cash flows discounted at the loan’s original interest rate by the various homogeneous categories of loans. All loans have been adjusted to reflect changes in credit risk and represent the exit price of the loans. Changes are not recorded directly as an adjustment to current earnings or comprehensive income, but rather as an adjustment component in determining the overall adequacy of the loan loss reserve. Other Real Estate Owned. OREO is reported at its net realizable value (fair value less estimated costs to sell) at the time any real estate collateral is acquired by the Bank in satisfaction of a loan. Subsequently, OREO is carried at the lower of carrying value or fair value less estimated costs to sell. Fair value is determined based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price or a current appraised value, we record the foreclosed asset at Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, we record the foreclosed asset at Level 3. Other Foreclosed Assets. Other foreclosed assets are reported at their net realizable value (fair value less estimated costs to sell) at the time any collateral other than real estate is acquired by the Bank in satisfaction of a loan. Subsequently, other foreclosed assets are carried at the lower of carrying value or fair value less estimated costs to sell. Fair value is determined based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price or a current appraised value, we record the foreclosed asset at Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, we record the foreclosed asset at Level 3. Deposits. Deposits are carried at historical cost. The carrying amounts of deposits from savings and money market accounts are deemed to approximate fair value as they either have no stated maturities or short-term maturities. Certificates of deposit are estimated utilizing discounted cash flow techniques. The interest rates applied are rates currently being offered for similar certificates of deposit. Borrowings. The fair value of borrowings is the carrying amount for those borrowings that mature on a daily basis. The fair value of term borrowings is derived by calculating the discounted value of future cash flows expected to be paid out by the Company. We classify our borrowings in Level 2 of the fair value hierarchy. Junior Subordinated Debentures. The fair value of the junior subordinated debentures is based on quoted market prices of the underlying securities. These securities are variable rate in nature and repriced quarterly. We classify our junior subordinated debentures in Level 2 of the fair value hierarchy. Commitments to Extend Credit and Standby Letters of Credit. The fair value of commitments to extend credit and standby letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing.
