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 Business Oversight 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. PM Asset Resolution, Inc. (“PMAR”) was a wholly owned subsidiary of PMBC, which existed for the purpose of purchasing certain non-performing loans and other real estate from the Bank and thereafter collecting on or disposing of those assets. PMAR was dissolved and all remaining capital was returned to PMBC during the third quarter of 2018. PMBC, the Bank and PMAR are sometimes referred to, together, on a consolidated basis, in this report as the “Company” or as “we”, “us” or “our”.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Except as discussed below, our accounting policies are described in Note 2, Significant Accounting Policies of our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018 (“Form 10-K”). Interim Consolidated Financial Statements Basis of Presentation Our interim consolidated financial statements are prepared in accordance with generally accepted accounting principles in effect in the United States (“GAAP”) for interim financial information pursuant to rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”), including instructions to Form 10-Q and Article 10 of Regulation S-X, on a basis consistent with prior periods. Our financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of the results for the interim periods presented. The interim results are not necessarily indicative of operating results for the full year. The interim information should be read in conjunction with our audited consolidated financial statements in our Form 10-K. 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. For the fiscal periods covered by this report, those estimates related 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 the 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 three and nine months ended September 30, 2019 and 2018 include the accounts of PMBC, the Bank and PMAR; PMAR was liquidated during the third quarter of 2018. All significant intercompany balances and transactions were eliminated in consolidation. Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842),” which requires lessees to recognize the following for all leases (with the exception of short-term leases) at the commencement date: a lease liability measured on a discounted basis and a right-of-use asset a specified asset for the lease term. The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. Under the new guidance, lessor accounting is largely unchanged and the accounting for sale and leaseback transactions were simplified. We elected most of the new standard’s available transition practical expedients. The new standard had a material effect on our financial statements. While we continue to assess all of the effects of adoption, we currently believe the most significant effects relate to (1) the recognition of new ROU assets and lease liabilities on our balance sheet for our office and equipment operating leases; and (2) providing significant new disclosures about our leasing activities. The new standard also provides practical expedients for an entity’s ongoing accounting. We have elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, we did not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. In July 2018, the FASB issued ASU 2018-11, “Leases (Topic 842): Targeted Improvements,” which provides an additional transition method upon adoption of ASU 2016-02. The guidance allows an entity to apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to beginning retained earnings in the period of adoption. In March 2019, the FASB issued ASU 2019-01, “Leases (Topic 842): Codification Improvements,” which provides additional guidance for fair value of the underlying asset by lessors that are not manufacturers or dealers, requires lessors that are banking institutions to present all "principal payments received under leases" within investing activities, and exempts both lessees and lessors from having to provide certain interim disclosures in the fiscal year in which a company adopts the new leases standard. On adoption of these accounting standards, we recognized additional operating liabilities of $11.1 million , with corresponding ROU assets of the same or less amount based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases. We recorded a $207 thousand adjustment to our beginning retained earnings. This guidance is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. We adopted this guidance on January 1, 2019. 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. In October 2019, the FASB confirmed that it will be moving forward with finalizing its proposal to defer the effective date for this guidance for smaller reporting companies from the interim and annual periods beginning after December 15, 2020 to the interim and annual periods beginning after December 15, 2022. For this effective date deferral to take effect, the FASB must issue the final ASU which we expect to be issued in mid-November. 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 August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement,” which amends the disclosure requirements related to fair value. The guidance removes disclosure related to transfers between Level 1 and Level 2 of the fair value hierarchy, the timing of these transfers and the valuation processes for Level 3 fair value measurements. Additional disclosures required as a result of adoption of this ASU will include the change in Level 3 unrealized gains and losses included in other comprehensive income and the range and weighted average of significant observable inputs used to develop Level 3 fair value measurements. This guidance is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures upon issuance of ASU 2018-13 and delay adoption of the additional disclosure requirements until their effective date. We are currently evaluating this guidance to determine the date of adoption and impact on the Company.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Under FASB Accounting Standards Codification (“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 customer relationships and the value of assets and liabilities that are not considered financial instruments, such as premises and equipment and other real estate owned (“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 three and nine months ended September 30, 2019 , we purchased no FHLB or FRBSF stock. No shares of FHLB stock or FRBSF stock were called during the three and nine months ended September 30, 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 September 30, 2019 and December 31, 2018 : At September 30, 2019 (Dollars in thousands) Total Level 1 Level 2 Level 3 Assets at Fair Value: Debt securities available for sale U.S. Treasury securities $ — $ — $ — $ — Commercial mortgage backed securities issued by U.S. Agencies 4,424 — 4,424 — Residential mortgage backed securities issued by U.S. agencies 20,549 — 20,549 — Total debt securities available for sale at fair value $ 24,973 $ — $ 24,973 $ — At December 31, 2018 (Dollars in thousands) Total Level 1 Level 2 Level 3 Assets at Fair Value: Debt securities available for sale U.S. Treasury securities $ 2,980 $ — $ 2,980 $ — Commercial mortgage backed securities issued by U.S. Agencies 4,534 — 4,534 — Residential mortgage backed securities issued by U.S. agencies 23,717 — 23,717 — Total debt securities available for sale 31,231 — 31,231 — 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 the 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.

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 September 30, 2019 and December 31, 2018 : (Dollars in thousands) September 30, 2019 December 31, 2018 Amortized Cost Gross Unrealized Estimated Fair Value Amortized Cost Gross Unrealized Estimated Fair Value Gain Loss Gain Loss Securities Available for Sale U.S. Treasury securities $ — $ — $ — $ — $ 2,999 $ — $ (19 ) $ 2,980 Commercial mortgage backed securities issued by U.S. Agencies (1) 4,247 177 — 4,424 4,495 40 (1 ) 4,534 Residential mortgage backed securities issued by U.S. Agencies (2) 20,749 7 (207 ) 20,549 24,739 1 (1,023 ) 23,717 Total $ 24,996 $ 184 $ (207 ) $ 24,973 $ 32,233 $ 41 $ (1,043 ) $ 31,231 (1) Secured by first liens on commercial apartment building mortgages. (2) Secured by closed-end first liens on 1-4 family residential mortgages. At September 30, 2019 and December 31, 2018 , U.S. agency residential mortgage backed securities with an aggregate fair market value of $9.8 million and $18.2 million , respectively, were pledged to secure repurchase agreements, local agency deposits and treasury, tax and loan accounts. The amortized cost and estimated fair values of securities available for sale at September 30, 2019 and December 31, 2018 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.

We purchased $2.5 million of securities available for sale during the three and nine months ended September 30, 2018. During the nine months ended September 30, 2018, we had sales proceeds of $2.1 million on the sale of debt securities available for sale, with a gain of $53 thousand , and sales proceeds of $4.8 million on the sale of our equity securities, with a loss of $5 thousand . We had no sales of securities available for sale during the three months ended September 30, 2018 or the three and nine months ended September 30, 2019 . The tables below indicate, as of September 30, 2019 and December 31, 2018 , 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.

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. 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. Through the impairment assessment process, we determined that there were no available-for-sale debt securities that were other-than-temporarily impaired at September 30, 2019 . We recorded no impairment credit losses on available-for-sale debt securities in our consolidated statements of operations for the three and nine months ended September 30, 2019 and 2018 . We have made a determination that the remainder of our securities with respect to which there were unrealized losses as of September 30, 2019 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 September 30, 2019 , we had three investments in private companies and limited partnerships without a readily determinable fair value. As of September 30, 2019 , we owned less than 3% of the total investment in each such company or 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 three and nine months ended September 30, 2019 , these investments were not impaired and there were no observable price changes. As a result, the balance shown below as of September 30, 2019 represents the cost of the investments and is included within other assets on the consolidated statements of financial condition. Prior to the adoption of ASU 2016-01, these investments were accounted for under the cost method of accounting and included within other assets on the consolidated statements of financial condition. During the three and nine months ended September 30, 2019 , we had zero and $876 thousand , respectively, of capital contributions to these investments. We had $34 thousand and $175 thousand , respectively, of capital contributions to these investments during the three and nine months ended September 30, 2018 . As of September 30, 2019 and December 31, 2018 , our equity investments without readily determinable fair value were as follows: September 30, 2019 December 31, 2018 (Dollars in thousands) Equity investments without readily determinable fair value $ 2,117 $ 1,240

At September 30, 2019 and December 31, 2018 , commercial and consumer loans of $267 million and $51 million , respectively, were pledged to secure borrowings from the FRB to support our unfunded borrowing capacity. During the three and nine months ended September 30, 2019, we sold $3.0 million and $10.1 million , respectively, of Small Business Administration (SBA) loans at a premium. During the nine months ended September 30, 2018, we sold $15.1 million of commercial real estate loans - all other at par value. No loans were sold during the three months ended September 30, 2018. During the three and nine months ended September 30, 2019 , we purchased loans totaling $81.0 million and $123.1 million , respectively, of which $81.0 million were multi-family mortgage loans and $39.9 million were consumer loans. We purchased no loans during the three and nine months ended September 30, 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 nonaccrual 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.

There were no loans 90 days or more past due and still accruing interest at September 30, 2019 . There were $1.3 million of loans 90 days or more past due and still accruing interest at December 31, 2018 . In certain instances, when a loan is placed on nonaccrual status, previously accrued but unpaid interest is reversed against current income. Subsequent collections of cash are applied as principal reductions when received (referred to as full nonaccrual basis of accounting), 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 (referred to as nonaccrual cash basis of accounting). Nonaccrual 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 September 30, 2019 and December 31, 2018 : September 30, 2019 December 31, 2018 (Dollars in thousands) Nonaccrual loans: Commercial loans $ 6,849 $ 3,352 Commercial real estate loans – owner occupied 6,266 831 Consumer 94 43 Total (1) $ 13,209 $ 4,226 (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 September 30, 2019 and December 31, 2018 : September 30, 2019 December 31, 2018 (Dollars in thousands) Impaired loans: Nonaccruing loans $ 13,209 $ 4,226 Nonaccruing restructured loans (1) — — Accruing restructured loans (1)(2) — — Total impaired loans $ 13,209 $ 4,226 Impaired loans less than 90 days delinquent and included in total impaired loans $ 13,205 $ 1,232 (1) As of September 30, 2019 and December 31, 2018, we had no restructured loans. (2) See “ Troubled Debt Restructurings ” below for a description of accruing restructured loans at September 30, 2019 and December 31, 2018. The table below contains additional information with respect to impaired loans, by portfolio type, as of September 30, 2019 and December 31, 2018 : September 30, 2019 December 31, 2018 Recorded Investment Unpaid Principal Balance Related Allowance (1) Recorded Investment Unpaid Principal Balance Related Allowance (1) (Dollars in thousands) No allowance recorded: Commercial loans $ 6,849 $ 8,427 $ — $ 3,352 $ 4,516 $ — Commercial real estate loans – owner occupied 6,266 6,395 — 831 925 — Consumer loans 94 127 — 43 65 — Total 13,209 14,949 — 4,226 5,506 — With allowance recorded: Total — — — — — — Total Commercial loans $ 6,849 $ 8,427 $ — $ 3,352 $ 4,516 $ — Commercial real estate loans – owner occupied 6,266 6,395 — 831 925 — Consumer loans 94 127 — 43 65 — Total 13,209 14,949 — 4,226 5,506 — (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 September 30, 2019 and December 31, 2018 , there were $13.2 million and $4.2 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 September 30, 2019 for which no specific reserves were allocated, $0.8 million had been deemed impaired in the prior year. Average balances and interest income recognized on impaired loans, by portfolio type, for the three and nine months ended September 30, 2019 and 2018 were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Average Balance Interest Income Recognized Average Balance Interest Income Recognized Average Balance Interest Income Recognized Average Balance Interest Income Recognized (Dollars in thousands) No allowance recorded: Commercial loans $ 3,658 $ 190 $ 4,700 $ 39 $ 2,786 $ 394 $ 4,256 $ 101 Commercial real estate loans – owner occupied 3,524 118 856 — 2,171 237 871 — Commercial real estate loans – all other — — — — — — 762 — Residential mortgage loans – single family — — — — — — 43 — Consumer loans 95 — 48 — 68 2 51 — Total 7,277 308 5,604 39 5,025 633 5,983 101 With allowance recorded: Commercial loans — — — — — — 209 — Total — — — — — — 209 — Total Commercial loans 3,658 190 4,700 39 2,786 394 4,465 101 Commercial real estate loans – owner occupied 3,524 118 856 — 2,171 237 871 — Commercial real estate loans – all other — — — — — — 762 — Residential mortgage loans – single family — — — — — — 43 — Consumer loans 95 — 48 — 68 2 51 — Total $ 7,277 $ 308 $ 5,604 $ 39 $ 5,025 $ 633 $ 6,192 $ 101 The interest that would have been earned had the impaired loans remained current in accordance with their original terms was $50 thousand and $131 thousand during the three months ended September 30, 2019 and 2018 , respectively, and $54 thousand and $293 thousand during the nine months ended September 30, 2019 and 2018 , respectively. Troubled Debt Restructurings (“TDRs”) Pursuant to the FASB's ASU No. 2011-2, A Creditor’s Determination of whether a Restructuring is a Troubled Debt Restructuring , the Bank's TDRs totaled $0 at both September 30, 2019 and December 31, 2018 . 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 form 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. There were no loans restructured as TDRs during the three and nine months ended September 30, 2019 or 2018 .

Leases

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. Generally, we consider any additional renewal periods to be reasonably certain of being exercised. 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 three and nine months ended September 30, 2019 , we recognized rent expense associated with our leases as follows: Three Months Ended September 30, Nine Months Ended September 30, 2019 2019 Lease cost (Dollars in thousands) Finance lease cost: Operating lease cost 585 $ 1,688 Short-term lease cost (1) 29 119 Total lease cost $ 614 $ 1,807 Weighted-average remaining lease term—operating leases (in years) 5.61 (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 September 30, 2019 is 1.57% . Supplemental balance sheet information related to leases was as follows: Financial Statement Classification September 30, 2019 (Dollars in thousands) Operating right-of-use assets Other assets $ 12,029 Operating lease liabilities Other liabilities $ 12,869 During the nine months ended September 30, 2019 , we had the following cash and non-cash activities associated with our leases: Nine Months Ended September 30, 2019 (Dollars in thousands) Cash paid for amounts included in the measurement of lease liabilities Operating cash flows from operating leases (fixed payments) $ 1,688 Non-cash activities: Right-of-use assets obtained in exchange for new operating lease liabilities $ 12,625 As a result of the Bank’s renewal of the lease of its headquarters, the ROU asset increased from $9.9 million at June 30, 2019 to 12.6 million at September 30, 2019 . Maturities of operating lease liabilities as of September 30, 2019 are as follows: (Dollars in thousands) For the years ending December 31, Remainder of 2019 562 2020 2,289 2021 2,359 2022 2,440 2023 2,522 2024 and beyond 3,565 Total 13,737 Less: Imputed interest 868 Total Lease liabilities 12,869

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three and nine months ended September 30, 2019 , we had income tax expense of $0.7 million and $2.2 million , respectively, as a result of our operating income. 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 September 30, 2019 . 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 twelve trailing quarters of positive income and our forecast. Negative evidence included our accumulated deficit. For the three and nine months ended September 30, 2018 , we had an income tax benefit of $98 thousand and $11.2 million , respectively, as a result of our net income during the third quarter of 2018 and the release of our full valuation allowance of $11.1 million on our net deferred tax asset during the second quarter of 2018. During the three months ended September 30, 2018 , management determined that there continued to be enough positive evidence to support no valuation allowance on our deferred tax asset. For the three months ended June 30, 2018, management evaluated the positive and negative evidence and determined that the valuation allowance that was previously established on the balance of our deferred tax asset was no longer required and released the entire $11.1 million . During the three months ended September 30, 2018 , management determined that there continued to be enough positive evidence to support no valuation allowance on our deferred tax asset. Based on this evaluation, management believed that the Company would be able to realize the deferred tax asset within the period that our operating losses may be carried forward. 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 eight trailing quarters of positive income and our forecast. Negative evidence at September 30, 2018 included our accumulated deficit. We file income tax returns with the U.S. federal government and the State of California. As of September 30, 2019, we were subject to examination by the Internal Revenue Service with respect to our U.S. federal tax returns for the 2015 to 2017 tax years and the Franchise Tax Board for California state income tax returns for the 2014 to 2017 tax years. Net operating losses on our U.S. federal and California state income tax returns may be carried forward up to 20 years. As of September 30, 2019, we do not have any unrecognized tax benefits. Our policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of tax expense. We did not have any accrued interest or penalties associated with any unrecognized tax benefits, and no interest expense was recognized during the three and nine months ended September 30, 2019 and 2018.

Share-based Payment Arrangement [Abstract]
Stock-Based Employee Compensation Plans	Stock-Based Employee Compensation Plans In 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”). Options to purchase a total of 6,003 shares of our common stock granted under the Previously Approved Plans were outstanding at September 30, 2019 . As of September 30, 2019 , there were options to purchase a total of 832,673 shares of our common stock and 137,692 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. 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. As of September 30, 2019 , there were outstanding options to purchase a total of 250,000 shares of our common stock, 100,000 shares of our unvested restricted stock units, and 2,656 shares of our unvested restricted stock grants under the 2019 Incentive Plan. As of September 30, 2019 , there remain 1,493,360 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. Stock Appreciation Rights (“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 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 September 30, 2019 were estimated as of their respective dates of grant using the Black-Scholes option-pricing model. The Company 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 to five years for employees and one year for directors while the stock units vest over a period of one to five years. The recipients of restricted shares have the right to vote all shares subject to such grant and receive all dividends with respect to such shares whether or not the shares have vested. The recipients of stock units have no rights of a stockholder. The recipients do not pay any cash consideration for the shares or stock units. Stock Options The table below summarizes the weighted average assumptions used to determine the fair values of the options granted during the following periods: Three Months Ended September 30, Nine Months Ended September 30, Assumptions with respect to: 2019 2018 (1) 2019 2018 Expected volatility 27 % — % 27 % 30 % Risk-free interest rate 1.35 % — % 1.35 % 2.69 % Expected dividends — % — % — % — % Expected term (years) 5.1 0.0 5.1 5.8 Weighted average fair value of options granted during period $ 1.97 $ — $ 1.97 $ 2.81 (1) No stock options were granted during the three months ended September 30, 2018.

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 three and nine months ended September 30, 2019 and 2018 .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments To meet the financing needs of our customers 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 September 30, 2019 and December 31, 2018 , we were committed to fund certain loans including letters of credit amounting to approximately $286 million and $302 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, represent the amount of potential accounting loss should the commitment be fully drawn upon, the customer were to default, and the value of any existing collateral securing the customer’s payment obligation becomes worthless. The loss reserve for unfunded loan commitments was $350 thousand at both September 30, 2019 and December 31, 2018 . 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 customer’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 customer. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, residential real estate and income-producing commercial properties. Borrowings At September 30, 2019 and December 31, 2018 , our borrowings and contractual obligations consisted of the following: (Dollars in thousands) September 30, 2019 December 31, 2018 FHLB advances—short-term $ 40,000 $ 40,000 FHLB advances—long-term — — Total $ 40,000 $ 40,000 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 2.17% for the nine months ended September 30, 2019 . Principal Amounts Interest Rate Maturity Dates (Dollars in thousands) 10,000 2.52 % November 29, 2019 10,000 2.19 % December 26, 2019 10,000 2.00 % December 30, 2019 10,000 1.97 % March 30, 2020 At September 30, 2019 , $436 million of loans were pledged to support our FHLB borrowings and our unfunded borrowing capacity. As of September 30, 2019 , we had unused borrowing capacity of $273 million with the FHLB. The highest amount of borrowings outstanding at any month-end during the three months ended September 30, 2019 was $40 million . At September 30, 2019 and December 31, 2018 , commercial and consumer loans of $257 million and $51 million , respectively, were pledged to secure borrowings from the FRB to support our unfunded borrowing capacity of $183 million . As of December 31, 2018 , we had $40.0 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 2.54% for the year ended December 31, 2018 . As of December 31, 2018 , we had unused borrowing capacity of $365 million with the FHLB. The highest amount of borrowings outstanding at any month-end during the year ended December 31, 2018 was $40.9 million . 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. In December 2016, following an ongoing review related to alleged discriminatory practices within our discontinued mortgage banking business, we received notice that the U.S. Department of Justice (“DOJ”) had authorized a potential enforcement action against the Bank. During the year ended December 31, 2018, we settled this matter with the DOJ for $1.0 million , which we have fully accrued and funded as of September 30, 2019 . Based on our evaluation of the remaining lawsuits and other proceedings that were pending against us as of September 30, 2019 , 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.

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.

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Capital	Regulatory Capital 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 following table sets forth the capital and capital ratios of the Bank (on a stand-alone basis) at September 30, 2019 , as compared to the regulatory requirements applicable to it. Applicable Federal Regulatory Requirement 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 168,838 13.2 % 123,694 At least 8.625 $ 127,979 At least 10.0 Common Equity Tier 1 Capital to Risk Weighted Assets 156,402 12.2 % 65,589 At least 5.125 $ 83,186 At least 6.5 Tier 1 Capital to Risk Weighted Assets 156,402 12.2 % 84,786 At least 6.625 $ 102,383 At least 8.0 Tier 1 Capital to Average Assets 156,402 10.9 % 57,366 At least 4.0 $ 71,707 At least 5.0 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 correct 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 September 30, 2019 , the Bank (on a stand-alone basis) continued to qualify as a well-capitalized institution under the capital adequacy guidelines described above. On September 17, 2019, the FDIC finalized a rule that introduces an optional simplified measure of capital adequacy for qualifying community banking organizations (i.e., the community bank leverage ratio (CBLR) framework), as required by the Economic Growth, Regulatory Relief and Consumer Protection Act. The CBLR framework is designed to reduce burden by removing the requirements for calculating and reporting risk-based capital ratios for qualifying community banking organizations that opt into the framework. In order to qualify for the CBLR framework, a community banking organization must have a tier 1 leverage ratio of greater than 9.0%, less than $10 billion in total consolidated assets, and limited amounts of off-balance-sheet exposures and trading assets and liabilities. A qualifying community banking organization that opts into the CBLR framework and meets all requirements under the framework will be considered to have met the well-capitalized ratio requirements under the Prompt Corrective Action regulations and will not be required to report or calculate risk-based capital. The CBLR framework will be available for banks to use in their March 31, 2020, Call Report. The Company has not yet determined if it will opt into the CBLR framework for the Bank.

Significant Accounting Policies - (Policies)	9 Months Ended

Accounting Policies [Abstract]
Interim Consolidated Financial Statements Basis of Presentation	Interim Consolidated Financial Statements Basis of Presentation Our interim consolidated financial statements are prepared in accordance with generally accepted accounting principles in effect in the United States (“GAAP”) for interim financial information pursuant to rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”), including instructions to Form 10-Q and Article 10 of Regulation S-X, on a basis consistent with prior periods. Our financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of the results for the interim periods presented. The interim results are not necessarily indicative of operating results for the full year. The interim information should be read in conjunction with our audited consolidated financial statements in our Form 10-K.
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. For the fiscal periods covered by this report, those estimates related 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 the 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 Consolidation Our consolidated financial statements for the three and nine months ended September 30, 2019 and 2018 include the accounts of PMBC, the Bank and PMAR; PMAR was liquidated during the third quarter of 2018. All significant intercompany balances and transactions were eliminated in consolidation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842),” which requires lessees to recognize the following for all leases (with the exception of short-term leases) at the commencement date: a lease liability measured on a discounted basis and a right-of-use asset a specified asset for the lease term. The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. Under the new guidance, lessor accounting is largely unchanged and the accounting for sale and leaseback transactions were simplified. We elected most of the new standard’s available transition practical expedients. The new standard had a material effect on our financial statements. While we continue to assess all of the effects of adoption, we currently believe the most significant effects relate to (1) the recognition of new ROU assets and lease liabilities on our balance sheet for our office and equipment operating leases; and (2) providing significant new disclosures about our leasing activities. The new standard also provides practical expedients for an entity’s ongoing accounting. We have elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, we did not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. In July 2018, the FASB issued ASU 2018-11, “Leases (Topic 842): Targeted Improvements,” which provides an additional transition method upon adoption of ASU 2016-02. The guidance allows an entity to apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to beginning retained earnings in the period of adoption. In March 2019, the FASB issued ASU 2019-01, “Leases (Topic 842): Codification Improvements,” which provides additional guidance for fair value of the underlying asset by lessors that are not manufacturers or dealers, requires lessors that are banking institutions to present all "principal payments received under leases" within investing activities, and exempts both lessees and lessors from having to provide certain interim disclosures in the fiscal year in which a company adopts the new leases standard. On adoption of these accounting standards, we recognized additional operating liabilities of $11.1 million , with corresponding ROU assets of the same or less amount based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases. We recorded a $207 thousand adjustment to our beginning retained earnings. This guidance is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. We adopted this guidance on January 1, 2019. 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. In October 2019, the FASB confirmed that it will be moving forward with finalizing its proposal to defer the effective date for this guidance for smaller reporting companies from the interim and annual periods beginning after December 15, 2020 to the interim and annual periods beginning after December 15, 2022. For this effective date deferral to take effect, the FASB must issue the final ASU which we expect to be issued in mid-November. 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 August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement,” which amends the disclosure requirements related to fair value. The guidance removes disclosure related to transfers between Level 1 and Level 2 of the fair value hierarchy, the timing of these transfers and the valuation processes for Level 3 fair value measurements. Additional disclosures required as a result of adoption of this ASU will include the change in Level 3 unrealized gains and losses included in other comprehensive income and the range and weighted average of significant observable inputs used to develop Level 3 fair value measurements. This guidance is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures upon issuance of ASU 2018-13 and delay adoption of the additional disclosure requirements until their effective date. We are currently evaluating this guidance to determine the date of adoption and impact on the Company.
Fair Value Measurements	Fair Value Measurements Under FASB Accounting Standards Codification (“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 customer relationships and the value of assets and liabilities that are not considered financial instruments, such as premises and equipment and other real estate owned (“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 three and nine months ended September 30, 2019 , we purchased no FHLB or FRBSF stock. No shares of FHLB stock or FRBSF stock were called during the three and nine months ended September 30, 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.
