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 small and medium-size 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. During the first quarter of 2013, PMBC organized a new wholly-owned subsidiary, PM Asset Resolution, Inc. ("PMAR"), for the purpose of purchasing certain non-performing loans and other real estate from the Bank and thereafter collecting or disposing of those assets. During the fourth quarter of 2013, the Bank announced the closure of our mortgage banking business, which was completed in the third quarter of 2014. The Bank operated a direct-to-consumer retail mortgage banking business, originating and funding residential mortgage loans and selling those loans, generally within the succeeding 30 days. Our mortgage banking operations are classified as discontinued operations within the financial statements and footnotes for all presented periods. 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 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 reserves 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, 2016 , 2015 and 2014 include the accounts of PMBC, the Bank and PMAR. All significant intercompany balances and transactions were eliminated in consolidation. Discontinued Operations The revenues and expenses of our mortgage banking division are reported in the consolidated statements of operations as discontinued operations for all periods presented. In determining whether the revenues and expenses are reported as discontinued operations, we evaluate whether we have any significant continuing involvement in the management of any of the mortgage banking operations. If we were to determine that we had any significant continuing involvement, the revenues and expenses of the respective operations would not be recorded in discontinued operations. As of December 31, 2016 and 2015 , we determined that the mortgage repurchase reserves are a liability of the Bank and are not included within the liabilities of discontinued operations. The repurchase reserves are included within other liabilities of the consolidated statements of financial condition. 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, 2016 and 2015 the Bank maintained required reserves with FRBSF of approximately $2,109,000 and $1,356,000 , 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. Loan Loss Obligation on Loans Previously Sold Upon a sale of mortgage loans held for sale (“LHFS”) that we have originated, the risk of loss due to default by the borrower is generally transferred to the investor. However, we are required to make certain representations to the purchasers of such loans relating to credit information, loan documentation and collateral. These representations and warranties may extend through the contractual life of the loan. If subsequent to the sale of such a loan, any underwriting deficiencies, borrower fraud or documentation defects are discovered with respect to the loan, we may become obligated to repurchase the loan or indemnify the investors for any losses from borrower defaults if such deficiencies or defects cannot be cured within the specified cure periods following their discovery. The obligation for losses attributable to any erroneous representations and warranties or other deficiencies or defects is recorded at its estimate of expected future losses using historical and projected loss frequency and loss severity ratios to estimate our exposure to such losses. In the case of early loan payoffs and early defaults on certain loans, we may be required to repay all or a portion of any premium initially paid by the purchaser of the loan at the time of sale. The obligations associated with early loan payoffs and early defaults on mortgage loans are estimated on the basis of historical loss experience by type of loan. 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 and $275,000 at December 31, 2016 and 2015 , respectively. 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. 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, 2016 . 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 to seven years 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 estimated 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. Forfeitures are required to be estimated at the time of the grant of options or other share awards and are revised, if necessary, in subsequent periods if actual forfeitures differ from those earlier estimates. For purposes of the determination of stock-based compensation expense for the year ended December 31, 2016 , we estimated forfeitures of 6.3% and 11.7% of the options and restricted stock that were granted to officers and other employees, respectively. 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, 2016 , 2015 and 2014 , 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 May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606),” which amended its guidance on revenue recognition to conform with international accounting guidance under the International Accounting Standards Board. The ASU provides a framework for addressing revenue recognition and replaces most existing revenue recognition guidance, as well as requires increased disclosure requirements. In August 2015, the FASB issued ASU 2015-14 to defer the effective date of ASU 2014-09 by one year. Accordingly, this guidance is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted for interim and annual periods beginning after December 15, 2016. We will adopt this guidance on January 1, 2018 using the modified retrospective approach. We expect the timing of revenue recognition to be accelerated as a result of the adoption of this guidance because it requires that loan origination fees be recognized at the time of origination, rather than over the life of the loan, which is the current practice. We expect this to create quarterly volatility within interest income as income will fluctuate based on the volume of originations in any given period. In addition, as the duration of our loan portfolio decreases, the impact of the recognition of our loan origination fees will diminish. We do not believe the impact to our beginning retained earnings will be material. In June 2014, the FASB issued ASU 2014-11, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period,” which amended its guidance on how to account for certain performance related share-based compensation plans. The amendments clarify the guidance on how to account for performance based awards when the requisite service period is met prior to potential performance targets being achieved. This guidance is effective for interim and annual periods beginning after December 15, 2015. Early adoption is permitted. We adopted this guidance on January 1, 2016 and it did not have a material effect on our consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements — Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern,” which defines management's responsibility to evaluate whether there is substantial doubt about an organization's ability to continue as a going concern and clarifies when to provide related footnote disclosure. This guidance is effective for interim and annual periods beginning after December 15, 2016. Early adoption is permitted. We adopted this guidance on January 1, 2017 and it had no effect on our consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis,” amends the guidance for assessing how relationships of related parties affect the consolidation analysis, eliminates the presumption that a general partner should consolidate a limited partnership, eliminates the consolidation model specific to limited partnerships, clarifies when fees paid to a decision maker should be a factor in consolidation of a variable interest entity, and reduces the number of variable interest entity consolidation models. This guidance is effective for interim and annual periods beginning after December 15, 2015. Early adoption is permitted. We adopted this guidance on January 1, 2016 and it did not have an impact on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs,” which requires that the debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. This simplifies the presentation of debt issuance costs and makes the presentation consistent with the presentation of debt discounts. This guidance is effective for interim and annual periods beginning after December 15, 2015. Early adoption is permitted. We adopted this guidance on January 1, 2016 and it did not have a material impact on our consolidated financial statements. In August 2015, the FASB issued ASU 2015-15, “Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements — Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting,” which clarifies the accounting for debt issuance costs for line-of-credit arrangements. We adopted this guidance on January 1, 2016 and it did not have a material impact on our consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,” which enhances the reporting model for financial instruments to provide users of financial statements with more useful information. Some of the provisions include: requiring equity investments to be measured at fair value with changes in fair value recognized in net income, simplifying the impairment assessment of equity investments without readily determinable fair values, eliminating the requirement to disclose the method and significant assumptions used to estimate fair value on financial instruments measured at amortized cost on the balance sheet, requiring public business entities to use the exit price notion when measuring the fair value of financial instruments, requiring the reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the organization has elected to measure the liability at fair value in accordance with the fair value option, requiring separate presentation of financial assets and liabilities by measurement category and form of financial asset on the balance sheet or notes to the financial statements, and clarifying that the reporting organization should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the organization's other deferred tax assets. This guidance is effective for interim and annual periods beginning after December 15, 2017. Early adoption is not permitted for public companies. We will adopt this guidance on January 1, 2018. We do not expect adoption of this guidance to have a material impact on our consolidated financial statements as we only have one available-for-sale equity investment where the change in fair value will be recognized in net income, as compared to the current practice of flowing through other comprehensive income. In February 2016, the FASB issued 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. Under the new guidance, lessor accounting is largely unchanged and the accounting for sale and leaseback transactions were simplified. This guidance is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. We will adopt this guidance on January 1, 2019. We expect our statement of financial condition to be grossed up on both the asset and liability side to reflect our lease obligations, and we do not expect adoption of this guidance to have a material impact on our other consolidated financial statements or on our disclosures related to leases. In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting,” which simplifies how several aspects of share-based payments are accounted for and presented in the financial statements. Under the new guidance, some of the aspects that are simplified include: income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This guidance is effective for interim and annual periods beginning after December 15, 2016. Early adoption is permitted. We adopted this guidance on January 1, 2017. As of December 31, 2016, we have excess tax benefits of approximately $211 thousand for which a benefit could not be previously recognized. Upon adoption, the balance of the unrecognized excess tax benefits will be reversed with the impact recorded to retained earnings including any change to the valuation allowance as a result of the adoption. Due to the full valuation allowance on the deferred tax assets, we do not expect any impact to our consolidated financial statements as a result of this adoption. Upon adoption of this guidance, we will elect to recognize forfeitures as they occur instead of applying an estimated forfeiture rate to each grant, which is the current practice. The expected impact to our beginning retained earnings is not expected to be material. On a prospective basis, we expect this could create quarterly volatility in our noninterest expense as forfeitures occur. 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. This guidance is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted for interim and annual periods beginning after December 15, 2018. We will adopt this guidance on January 1, 2020 and expect that it will have a material impact on the determination of our ALLL and an increased ALLL. We are unable to estimate the expected impact to the ALLL upon adoption due to various factors, primarily the 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 gathering the supplemental data needed 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 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which provides guidance for classification of specific items on the statement of cash flows. This guidance is effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted. We will adopt this guidance on January 1, 2018 and do not expect it to have a material impact on our statement of cash flows. In January 2017, the FASB issued ASU 2017-03, “Accounting Changes and Error Corrections (Topic 250) and Investments - Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 16, 2016 EITF Meetings,” which incorporates into FASB accounting standards recent SEC guidance requiring expanded disclosure on the effect of implementation in advance of a company's adoption of a new accounting standard, specifically those related to revenue recognition, leases, financial instruments and credit losses. This guidance is effective immediately. We adopted this guidance upon the date of issuance and have increased the disclosure of the effect of recently issued accounting standards on future periods in this Form 10-K. We will continue to provide expanded disclosure and updates on the estimated effect of recently issued accounting guidance through the period of adoption. This guidance only affected the financial statement footnote disclosures and had no impact on the financial statements. 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

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2016
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 customer 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 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, 2016 , we purchased $0 thousand in value of FHLB stock and no shares of FRBSF stock. 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, U.S. Treasury securities that are traded by dealers or brokers in active over-the- counter markets and money market funds. 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. 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 discounted value of future cash flows expected to be received by the various homogeneous categories of loans. All loans have been adjusted to reflect changes in credit risk. 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. We typically classify our loans held for investment in Level 3 of the fair value hierarchy. 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. 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. We typically classify our noninterest bearing deposits in Level 1 and all remaining deposits in Level 2 of the fair value hierarchy. 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, 2016 and 2015 . At December 31, 2016 (Dollars in thousands) Total Level 1 Level 2 Level 3 Assets and Liabilities at Fair Value: Investment securities available for sale Mortgage backed securities issued by U.S. agencies $ 36,675 $ — $ 36,675 $ — Collateralized mortgage obligations issued by non-agency 468 — 468 — Asset-backed securities 1,433 — — 1,433 Mutual funds 4,904 4,904 — — Total securities available for sale at fair value $ 43,480 $ 4,904 $ 37,143 $ 1,433 At December 31, 2015 (Dollars in thousands) Total Level 1 Level 2 Level 3 Assets and Liabilities at Fair Value: Investment securities available for sale Mortgage backed securities issued by U.S. agencies $ 45,154 $ — $ 45,154 $ — Collateralized mortgage obligations issued by non agency 632 — 632 — Asset-backed securities 1,480 — — 1,480 Mutual funds 4,983 4,983 — — Total securities available for sale at fair value $ 52,249 $ 4,983 $ 45,786 $ 1,480 The changes in Level 3 assets measured at fair value on a recurring basis are summarized as follows for the year ended December 31, 2016 : Asset Backed Securities (Dollars in thousands) Balance of recurring Level 3 instruments at December 31, 2015 $ 1,480 Total gains or losses (realized/unrealized): Included in other comprehensive income (47 ) Settlements — Transfers in and/or out of Level 3 — Balance of Level 3 assets at December 31, 2016 $ 1,433 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, 2016 Total Level 1 Level 2 Level 3 Assets at Fair Value: (Dollars in thousands) Impaired loans $ 24,897 $ — $ — $ 24,897 Total $ 24,897 $ — $ — $ 24,897 There were no transfers in or out of Level 3 measurements for nonrecurring items during the year ended December 31, 2016 . 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, 2016 , a summary of the significant unobservable inputs and valuation techniques is as follows: Fair Value Measurement as of December 31, 2016 Valuation Techniques Unobservable Inputs Range Weighted Average (Dollars in thousands) Assets Asset-backed security $ 1,433 Third-Party Pricing Marketability discount N/A (1) Illiquidity discount N/A (1) Impaired loans 24,897 Third-Party Pricing Appraisals N/A (2) $ 26,330 (1) Information is unavailable as valuation was obtained from third-party pricing services. (2) 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) Comprised of a security that represents an interest in a pool of trust preferred securities issued by U.S.-based banks and insurance companies. (3) Consists primarily of mutual fund investments in closed-end first lien 1-4 family residential mortgages. At December 31, 2016 and 2015 , U.S. agency mortgage backed securities and collateralized mortgage obligations with an aggregate fair market value of $21.1 million and $2.9 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, 2016 and December 31, 2015 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.

The tables below indicate, as of December 31, 2016 and 2015 , 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 intent and 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 (loss). Through the impairment assessment process, we determined that the available-for-sale securities discussed below were other-than-temporarily impaired at December 31, 2016 . We recorded no impairment credit losses on available-for-sale securities in our consolidated statements of operations for the years ended December 31, 2016 and 2015 . The OTTI related to factors other than credit losses, in the aggregate amount of $592 thousand , was recognized as other comprehensive loss in our accompanying consolidated statement of financial condition. The table below presents, for the years ended December 31, 2016 and 2015 , a roll-forward of OTTI in those instances when a portion of the OTTI was attributable to non-credit related factors and, therefore, was recognized in other comprehensive loss: (Dollars in thousands) Gross Other- Than- Temporary Impairments Other-Than- Temporary Impairments Included in Other Comprehensive Loss Net Other-Than- Temporary Impairments Included in Retained Earnings (Deficit) Balance – December 31, 2014 $ (986 ) $ (433 ) $ (553 ) Changes in market value on securities for which an OTTI was previously recognized (166 ) (166 ) — Principal received on OTTI security 52 52 — Balance – December 31, 2015 $ (1,100 ) $ (547 ) $ (553 ) Change in market value on a security for which an OTTI was previously recognized (47 ) (47 ) — Principal received on OTTI security 2 2 — Balance – December 31, 2016 $ (1,145 ) $ (592 ) $ (553 ) In determining the component of OTTI related to credit losses, we compare the amortized cost basis of each OTTI security to the present value of its expected cash flows, discounted using the effective interest rate implicit in the security at the date of acquisition. As a part of our OTTI assessment process with respect to securities held for sale with unrealized losses, we consider available information about (i) the performance of the collateral underlying each such security, including any credit enhancements, (ii) historical prepayment speeds, (iii) delinquency and default rates, (iv) loss severities, (v) the age or “vintage” of the security, and (vi) any rating agency reports on the security. Significant judgments are required with respect to these and other factors in order to make a determination of the future cash flows that can be expected to be generated by the security. Based on our OTTI assessment process, we determined that there is one asset-backed security in our portfolio of securities held for sale that was impaired as of December 31, 2016 . This security is a multi-class, cash flow collateralized bond obligation backed by a pool of trust preferred securities issued by a diversified pool of 56 issuers that consisted of 45 U.S. depository institutions and 11 insurance companies at the time of the security’s issuance in November 2007. We purchased $3.0 million face amount of this security in November 2007 at a price of 95.21% for a total purchase price of $2.9 million , out of a total of $363 million of this security sold at the time of issuance. The security that we own (CUSIP 74042CAE8) is the mezzanine class B piece security with a variable interest rate of 3 month LIBOR plus 60 basis points, which had a rating of Aa2 and AA by Moody’s and Fitch, respectively, at the time of issuance in 2007. As of December 31, 2016 the amortized cost of this security was $2.0 million with a fair value of $1.4 million , for an unrealized loss of approximately $592 thousand . As of December 31, 2016 , the security had a Baa3 rating from Moody’s and a B rating from Fitch and had experienced $42.5 million in defaults ( 12.5% of total current collateral) and $7.0 million in deferring securities ( 2.1% of total current collateral) from issuance to December 31, 2016 . As of December 31, 2016 , the mezzanine class B tranche had $59.7 million in excess subordination. We have made a determination that the remainder of our securities with respect to which there were unrealized losses as of December 31, 2016 are not other-than-temporarily impaired, because we have concluded that we have the intent and 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). Other Investments As of December 31, 2016 , we had one investment in a limited partnership which was accounted for under the cost method of accounting and included within other assets on the consolidated statements of financial condition. During the year ended December 31, 2016 and 2015, we contributed $385 thousand and $281 thousand , respectively, to this investment. During the year ended December 31, 2015, we redeemed 100% of our investment in a limited partnership accounted for under the equity method of accounting for a return of capital of $2.1 million . As of December 31, 2016 and December 31, 2015 , our other investment was as follows: December 31, 2016 2015 (Dollars in thousands) Investments accounted for under the cost method $ 666 $ 281

During the year ended December 31, 2016 , we purchased $85.8 million of performing residential multi-family mortgage and commercial real estate - all other loans. No loans were purchased during the years ended December 31, 2015 or 2014. 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 tracks 16 quarters 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.

Generally, the accrual of interest on a loan is discontinued when principal or interest payments become more than 90 days past due, unless we believe that the loan is adequately collateralized and it is in the process of collection. There were no loans 90 days or more past due and still accruing interest at December 31, 2016 or December 31, 2015 . 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.

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.

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, 2016 and December 31, 2015 there were $21.6 million and $24.2 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 December 31, 2016 for which no specific reserves were allocated, $12.3 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, 2016 , 2015 and 2014 were as follows: Year Ended December 31, 2016 2015 2014 Average Balance Interest Income Recognized Average Balance Interest Income Recognized Average Balance Interest Income Recognized No allowance recorded: Commercial loans $ 13,686 $ 437 $ 13,455 $ 178 $ 12,590 $ 782 Commercial real estate loans – owner occupied 2,455 3 2,494 115 2,088 18 Commercial real estate loans – all other 4,413 — 6,256 337 6,442 290 Residential mortgage loans – multi-family 350 — 451 13 — — Residential mortgage loans – single family 339 9 3,137 — 3,732 148 Land development loans 871 — 1,665 7 1,246 91 Consumer loans 173 — — — — — Total 22,287 449 27,458 650 26,098 1,329 With allowance recorded: Commercial loans 4,728 457 528 — 2,298 34 Commercial real estate loans – owner occupied 962 — 815 — 121 — Total 5,690 457 1,343 — 2,419 34 Total Commercial loans 18,414 894 13,983 178 14,888 816 Commercial real estate loans – owner occupied 3,417 3 3,309 115 2,209 18 Commercial real estate loans – all other 4,413 — 6,256 337 6,442 290 Residential mortgage loans – multi-family 350 — 451 13 — — Residential mortgage loans – single family 339 9 3,137 — 3,732 148 Land development loans 871 — 1,665 7 1,246 91 Consumer loans 173 — — — — — Total $ 27,977 $ 906 $ 28,801 $ 650 $ 28,517 $ 1,363 The interest that would have been earned had the impaired loans remained current in accordance with their original terms was $1.2 million in 2016 , $899 thousand in 2015 and $384 thousand in 2014 . 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's TDRs totaled $8.9 million and $20.8 million at December 31, 2016 and December 31, 2015 , respectively. 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. Of the $8.9 million of TDRs outstanding at December 31, 2016 , none were performing in accordance with their terms and accruing interest. Of the $8.9 million nonperforming TDRs, one loan relationship made up $6.7 million of the amount outstanding as of December 31, 2016. Our impairment analysis determined no specific reserves were required on the TDR balances outstanding at December 31, 2016 .

Borrowings and Contractual Obligations	Borrowings and Contractual Obligations At December 31, 2016 and 2015 , our borrowings and contractual obligations consisted of the following: December 31, (Dollars in thousands) 2016 2015 FHLB advances—short-term $ 15,000 $ 10,000 FHLB advances—long-term — — Total $ 15,000 $ 10,000 (1) The $15.0 million of FHLB advances in 2016 matured on January 3, 2017 and had an interest rate of 0.55% . Subsequent to December 31, 2016, this amount was repaid in full. At December 31, 2016 , $527 million of loans were pledged to support our FHLB borrowings and our unfunded borrowing capacity. As of December 31, 2016 , we had unused borrowing capacity of $272 million with the FHLB. The highest amount of borrowings outstanding at any month-end during the year ended December 31, 2016 was $15 million . As of December 31, 2015 , we had $10.0 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 1.02% for the year ended December 31, 2015 . As of December 31, 2015 we had unused borrowing capacity of $241 million with the FHLB. The highest amount of borrowings outstanding at any month-end during the year ended December 31, 2015 was $39.5 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, 2016 and 2015 : Original Issue Dates Principal Amount Interest Rate (1) Maturity Dates (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. We have committed to obtaining approval from the FRB and the CDBO prior to making any distributions representing interest, principal or other sums on subordinated debentures or trust preferred securities. Refer to “ Regulatory Matters ” above in Item 1 for further detail. As of December 31, 2016 , we were current on all interest payments. Under the Federal Reserve Board rulings, the borrowings evidenced by the Debentures, which are subordinated to all of our other borrowings that are outstanding or which we may obtain in the future, are eligible (subject to certain dollar limitations) to qualify and, at December 31, 2016 and 2015 , $17.0 million of those Debentures qualified as Tier I capital, for regulatory purposes.

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 14, Shareholders' Equity, and the transactions noted below, we have no other related party transactions. Previously, we conducted banking transactions with and made loans to and entered into loan commitments with members of our Board of Directors and certain of the businesses with which they are affiliated or associated. All such loans and loan commitments were made in accordance with applicable laws and government regulations and on substantially the same terms, including interest rates and collateral, as those prevailing at the same time for comparable transactions with persons of similar creditworthiness that are not affiliated with us and, when made, did not present any undue risk of collectability. As of December 31, 2015, we are no longer making loans or entering into loan commitments with members of our Board of Directors and their affiliates. As a result, the outstanding loan balance from December 31, 2014 of loans entered into with members of our Board of Directors was paid in full during the year ended December 31, 2015. The following is a summary of loan transactions with members of the Board of Directors and certain of their affiliates and associates: Year Ended December 31, (Dollars in thousands) 2016 2015 (1) Beginning balance $ — $ 96 New loans granted — — Principal repayments — (96 ) Ending balance $ — $ — (1) No loans made to executive officers who are not also directors.

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 increased. Any such increase would result in an income tax benefit. The components of our net deferred tax asset are as follows at: (Dollars in thousands) December 31, 2016 2015 Deferred tax asset: Allowance for loan and lease losses $ 6,932 $ 5,253 Other than temporary impairment on securities 78 78 Deferred compensation 1,033 1,098 Other accrued expenses 2,075 1,421 Charitable contributions 244 208 Reserve for unfunded commitments 144 113 Tax credits 158 158 Net operating loss carry forward 13,410 8,313 Stock based compensation 747 651 Depreciation and amortization 166 177 Unrealized losses on securities and deferred compensation 758 637 Total deferred tax assets 25,745 18,107 Deferred tax liabilities: State taxes 1 (230 ) Other (742 ) (301 ) Total deferred tax liabilities (741 ) (531 ) Valuation allowance (25,004 ) — Total net deferred tax asset $ — $ 17,576 During the year ended December 31, 2014 , we recorded an income tax benefit of $608 thousand . Per ASC 740-20-45-7 all sources of pre-tax income must be considered in determining the tax benefit that results from a loss from continuing operations and that shall be allocated to continuing operations. This benefit is the result of an intraperiod tax allocation where the benefit of the income tax provision that is recorded in discontinued operations and other comprehensive income created a tax benefit in continuing operations. On a net basis we recorded no income tax provision. Based on the analysis performed, and the positive and negative evidence considered, management chose not to release any portion of the $12.1 million valuation allowance as of December 31, 2014. Positive evidence included improvement in our asset quality, tax planning strategies, projected taxable income, and improvement in economic conditions. Negative evidence included historical operating losses. Management determined the negative evidence was significant enough that until such time as we are in continuous periods of pre-tax income we would not make any reversals of our valuation allowance; however, we did conclude that it is more-likely-than-not that the existing $5.9 million net deferred tax asset will be realized. During the year ended December 31, 2015 , we recorded an income tax benefit of $11.6 million . Management evaluated the positive and negative evidence and determined that there was enough positive evidence to support the full realization of the deferred tax asset and that no valuation allowance was needed. Positive evidence included projected taxable income utilizing objective assumptions based on 2015 actual results, tax planning strategies, improvement in economic conditions and at least 17 years remaining on the life of our $8.3 million deferred tax asset generated from our net operating loss carryforward. Additionally, the Company had generated positive core earnings for the trailing six quarters which demonstrated the ability to be profitable in what is considered to be the Company's core business. While the decision to exit the mortgage business in 2013 did not necessarily ensure that the Company would become profitable, the results provided positive evidence that the decision to exit the unprofitable business was sufficient to overcome the losses incurred in recent years. Negative evidence we considered in making this determination included our three-year cumulative loss deficit and our accumulated deficit. Management determined that the expectation of future taxable income supported by our recent history of positive core earnings after adjusting for aberrational items that caused our cumulative loss condition, including discontinued operations, provided enough positive evidence to outweigh the negative evidence. Therefore, we concluded that it was more-likely-than-not that the existing $17.6 million net deferred tax asset would be realized, resulting in the reversal of the entire valuation allowance against the Company's deferred tax asset. Although we did not expect to be required to pay income tax to the appropriate taxing authorities of any sizeable amount until we had depleted our net operating loss carryforwards, we expected to recognize income tax expense in our financial statements beginning in 2016 at a combined rate of approximately 41% on our pretax income. During the year ended December 31, 2016 , we had income tax expense of $16.8 million as a result of the establishment of a full valuation allowance during 2016 on the balance of our deferred tax asset, which includes current and historical losses that may be used to offset taxes on future profits. 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. Negative evidence included the significant losses incurred during the second and third quarters of 2016, an increase in our nonperforming assets from December 31, 2015, and our accumulated deficit. Positive evidence included our forecast of our taxable income, the time period in which we have to utilize our deferred tax asset and the current economic conditions. The tax code allows net operating losses to be carried forward for 20 years from the date of the loss, and while management believed that the Company would be able to realize the deferred tax asset within that period, we were unable to assert the timing as to when that realization would occur. As a result of this conclusion and due to the hierarchy of evidence that the accounting rules specify, a valuation allowance had been recorded as of December 31, 2016 to offset the deferred tax asset. As of December 31, 2016 , we had net operating loss carryforwards of $28.7 million and $54.2 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 (amounts in thousands) 2008 (1) $ — $ 4,368 12/31/2032 2009 (1) — 21,324 12/31/2032 2010 (1) — 5,258 12/31/2032 2012 852 774 12/31/2032 2013 14,977 8,967 12/31/2033 2015 288 280 12/31/2035 2016 12,569 13,237 12/31/2036 $ 28,686 $ 54,208 (1) California net operating loss carryforwards were suspended by the Franchise Tax Board during these periods and the carryover was extended. We file income tax returns with the U.S. federal government and the state of California. As of December 31, 2016, we were subject to examination by the Internal Revenue Service with respect to our U.S. federal tax returns for the 2013 to 2015 tax years and Franchise Tax Board for California state income tax returns for the 2012 to 2015 tax years. Net operating losses on our U.S. federal and California state income tax returns may be carried forward twenty years. As of December 31, 2016, we do not believe there will be any material adverse changes in our unrecognized tax benefits over the next 12 months. 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 years ended 2016 , 2015 and 2014.

An additional 158,211 shares of common stock were also set aside which was equal to the total of the shares that were available for the grant of equity incentives under our shareholder-approved 2008 and 2004 Equity Incentive Plans (the "Previously Approved Plans") at the time of the adoption of the 2010 Incentive Plan. Options to purchase a total of 347,520 shares of our common stock granted under the Previously Approved Plans were outstanding at December 31, 2016 . The 2010 Incentive Plan provides that if any of these outstanding options under the Previously Approved Plans expire or are terminated for any reason, then the number of shares that would become available for grants or awards of equity incentives under the 2010 Incentive Plan would be increased by an equivalent number of shares. At the Annual Shareholders meeting held in May 2013, our shareholders approved an additional 800,000 share increase in the maximum number of shares of our common stock that may be issued pursuant to grants or exercises of options or restricted shares or other equity incentives under the 2010 Incentive Plan, of which 67,456 shares of restricted stock vested during the year ended December 31, 2016 , thereby decreasing the maximum number of shares authorized under the 2010 Incentive Plan. As a result, as of December 31, 2016 , the maximum number of shares that were authorized for the grant of options or other equity incentives under the 2010 Incentive Plan totaled 1,531,205 (assuming that all 347,520 shares of our common stock subject to options under the Previously Approved Plans expire or are terminated), or approximately 7% of the shares of our common stock then outstanding. 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. Options, restricted shares and SARs 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 or the SARs. Stock options and SARs 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 or SAR. 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 or any restricted shares that we grant as compensation cost over their respective service periods. The fair values of the options that were outstanding at December 31, 2016 under the 2010 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, granted restricted stock for the benefit of its employees. These restricted shares vest over a period of three 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 do not pay any cash consideration for the shares. 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: 2016 2015 2014 Expected volatility 38 % 44 % 44 % Risk-free interest rate 1.70 % 1.82 % 2.15 % Expected dividends — % — % 0.61 % Expected term (years) 6.3 6.0 6.7 Weighted average fair value of options granted during period $ 2.78 $ 3.13 $ 2.84 The following table summarizes the stock option activity under the Company’s equity incentive plans during the years ended December 31, 2016 , 2015 and 2014 , respectively.

Compensation and Retirement Disclosure [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, 2016 , 2015 and 2014 were $342 thousand , $164 thousand , and $356 thousand , respectively. In January 2001, the Company established an unfunded Supplemental Retirement Plan (“SERP”) for our former CEO, Raymond E. Dellerba, 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 that, subject to meeting certain vesting requirements described below, upon reaching age 65 , Mr. Dellerba will become entitled to receive 180 equal successive monthly retirement payments, each in an amount equal to 60% of his average monthly base salary during the three years immediately preceding his reaching 65 years old (the “Monthly SERP Benefit”). Mr. Dellerba reached the age of 65 in January 2013 and, as a result, a monthly benefit payment under the SERP to Mr. Dellerba 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 2016 , 2015 and 2014 , its funded status at December 31, 2016 , 2015 and 2014 , and the amounts recognized in our consolidated statements of financial condition at each of those dates were as follows: At December 31, (Dollars in thousands) 2016 2015 2014 Change in benefit obligation: Benefit obligation at beginning of period $ 2,667 $ 2,815 $ 2,954 Service cost — — — Interest cost 150 159 168 Actuarial loss/(gain) — — — (Benefits paid) (306 ) (307 ) (307 ) Benefit obligation at end of period $ 2,511 $ 2,667 $ 2,815 Funded status: Amounts recognized in the Statement of Financial Condition Unfunded accrued SERP liability—current $ (299 ) $ (299 ) $ (299 ) Unfunded accrued SERP liability—noncurrent (2,212 ) (2,368 ) (2,516 ) Total unfunded accrued SERP liability $ (2,511 ) $ (2,667 ) $ (2,815 ) 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 $ 2,511 $ 2,667 $ 2,815 Components of net periodic SERP cost year to date: Service cost $ — $ — $ — Interest cost 150 159 168 Amortization of prior service cost/(benefit) — — — Amortization of net actuarial loss/(gain) — — — Net periodic SERP cost $ 150 $ 159 $ 168 As of December 31, 2016 , $1.5 million benefits are expected to be paid in the next five years and a total of $1.5 million of benefits are expected to be paid from year 2022 through year 2026. In 2017 , $141,000 is expected to be recognized in net periodic benefit cost.

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 available 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 years ended December 31, 2016 , 2015 and 2014 . (In thousands, except per share data) For the Year Ended December 31, 2016 2015 2014 Numerator: Net (loss) income from continuing operations $ (34,643 ) $ 12,441 $ (869 ) Accumulated declared dividends on preferred stock — — (547 ) Accumulated undeclared dividends on preferred stock — — (616 ) Dividends on preferred stock — (927 ) — Inducements for exchange of the preferred stock — (512 ) — Numerator for basic and diluted net (loss) income from continuing operations (34,643 ) 11,002 (2,032 ) Net income from discontinued operations — — 1,226 Numerator for basic and diluted net (loss) income available to common shareholders $ (34,643 ) $ 11,002 $ (806 ) Denominator: Basic weighted average outstanding shares of common stock 22,959 20,517 19,231 Dilutive effect of employee stock options and contingently issuable shares — 159 — Diluted weighted average common stock and common stock equivalents 22,959 20,675 19,231 Basic (loss) income per common share (1) : Net (loss) income from continuing operations $ (1.51 ) $ 0.54 $ (0.11 ) Net (loss) income from discontinued operations $ — $ — $ 0.07 Net (loss) income available to common shareholders $ (1.51 ) $ 0.54 $ (0.04 ) Diluted (loss) income per common share (1) : Net (loss) income from continuing operations $ (1.51 ) $ 0.53 $ (0.11 ) Net (loss) income from discontinued operations $ — $ — $ 0.07 Net (loss) income available to common shareholders $ (1.51 ) $ 0.53 $ (0.04 ) (1) The basic and diluted earnings per share amounts for the year ended December 31, 2015 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 Two-Class Method is not required for the years ended December 31, 2016 and 2014. 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, 2016 2015 2014 Stock options (1)(2) 1,038,317 360,600 1,746,696 Convertible securities (3) — — 2,602,707 Shares subject to stock purchase warrants (4) — — 761,278 (1) Stock options were excluded from the computation of diluted earnings per common share for the years ended December 31, 2016 and 2014 as we reported a net loss from continuing operations. (2) Stock options were excluded from the computation of diluted earnings per common share for the year ended December 31, 2015 because the options were either “out-of-the-money” or the effect of exercise would have been antidilutive. (3) Convertible securities were excluded from the computation of diluted earnings per common share for the year ended December 31, 2014 as we reported a net loss from continuing operations. (4) Stock purchase warrants were excluded from the computation of diluted earnings per common share for the year ended December 31, 2014 because the exercisability of those warrants was conditioned on the happening of certain future events.

Equity [Abstract]
Shareholders' Equity	Shareholders’ Equity Preferred Stock and Warrants On August 28, 2015, we entered into an Exchange Agreement (the “Exchange Agreement”) with SBAV, LP, an affiliate of Clinton Group, Inc. (“SBAV”), and the Carpenter Funds pursuant to which SBAV and the Carpenter Funds exchanged an aggregate of 112,000 shares of the Company’s Series B Convertible 8.4% Noncumulative Preferred Stock (the “Series B Shares”), 35,225 shares of the Series C 8.4% Noncumulative Preferred Stock (the “Series C Shares”) and warrants to purchase 761,278 shares of the Company’s common stock (the “Warrants”) for an aggregate of 3,009,148 shares of the Company’s common stock (the “Exchange Transaction”). The Series B Shares, Series C Shares and Warrants exchanged by SBAV and the Carpenter Funds in the Exchange Transaction comprised all of the Company’s outstanding shares of preferred stock and warrants to purchase shares of the Company’s common stock. The Exchange Transaction closed on September 30, 2015. Due to the ownership interests of SBAV and the Carpenter Funds at September 30, 2015, this transaction is considered to be a related party transaction. Accumulated Other Comprehensive Income, net Accumulated other comprehensive income, net as of December 31, 2016 , 2015 and 2014 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, 2014 $ (2,154 ) $ (2,154 ) Other comprehensive income before reclassifications, net of tax provision of $847 thousand (1) 1,462 1,462 Amounts reclassified from accumulated other comprehensive income, net of tax — — Other comprehensive income, net of tax provision of $847 thousand 1,462 1,462 Ending balance as of December 31, 2014 $ (692 ) $ (692 ) Other comprehensive income before reclassifications, net of tax provision of $81 thousand (1) (118 ) (118 ) Amounts reclassified from accumulated other comprehensive income, net of tax — — Other comprehensive income, net of tax provision of $81 thousand (118 ) (118 ) Ending balance as of December 31, 2015 $ (810 ) $ (810 ) Other comprehensive income before reclassifications, net of tax provision of $739 thousand (1) (1,032 ) (1,032 ) Amounts reclassified from accumulated other comprehensive income, net of tax — — Other comprehensive income, net of tax provision of $739 thousand (1,032 ) (1,032 ) Ending balance as of December 31, 2016 $ (1,842 ) $ (1,842 ) (1) Tax impact included in Deferred tax assets . 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. 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. During the years ended December 31, 2016 , 2015 and 2014 , we issued 0 , 5,917 , and 11,123 Series C Shares, respectively, in lieu of accumulated declared and undeclared dividends on the Series B Shares. As of December 31, 2016 and 2015 , we had no outstanding Series C Shares or Series B Shares as a result of the Exchange Transaction noted above in “Preferred Stock and Warrants.” 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. The ability of the Bank to pay dividends is further restricted under the Federal Deposit Insurance Corporation Improvement Act of 1991, which prohibits an FDIC-insured bank from paying dividends if, after making such payment, the bank would fail to meet any of its minimum capital requirements. Under the Financial Institutions Supervisory Act and Federal Financial Institutions Reform, Recovery and Enforcement Act of 1989, federal banking regulators also have authority to prohibit FDIC-insured financial institutions from engaging in business practices which are considered to be unsafe or unsound. Under the authority of these acts, federal bank regulatory agencies, as part of their supervisory powers, generally require FDIC insured banks to adopt dividend policies which limit the payment of cash dividends. We have agreed that the Bank will not, without the FRB and the CDBO's prior written approval, pay any dividends to Bancorp. Refer to “ Regulatory Matters ” above in Item 1 for further detail. As a result, it is not expected that the Bank will be permitted to pay cash dividends for the foreseeable future. While restrictions on the payment of dividends from the Bank to us exist, there are no restrictions on the dividends that PMAR may pay to the Company. PMAR has approximately $15.0 million in assets and could provide the Company with additional cash if required. We have committed to obtaining approval from the FRB and the CDBO prior to the Company paying any dividends. Refer to “ Regulatory Matters ” above in Item 1 for further detail.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Leases We lease certain facilities and equipment under various non-cancelable operating leases, which generally include 2% to 6% escalation clauses in the lease agreements. Rent expense for the years ended December 31, 2016 , 2015 and 2014 was $2.6 million , $2.8 million , and $2.6 million , respectively. Future minimum non-cancelable lease commitments were as follows at December 31, 2016 : (Dollars in thousands) 2017 $ 2,463 2018 2,069 2019 1,997 2020 901 2021 and beyond 105 Total $ 7,535 Contingent Liabilities Repurchase Reserves We have historically maintained reserves for possible repurchases that we may have been required to make of certain of the mortgage loans which we sold as a result of deficiencies or defects that may be found to exist in such loans. Our repurchase reserve also covered returns of any premiums earned and administrative fees pertaining to the repurchase of mortgage loans that did not meet investor guidelines, including potential loss of advances on Veterans Affairs or Federal Housing Authority Ginnie Mae loans. As a result of our exit from the mortgage banking business and no longer being subject to potential loss for anything other than mortgage fraud, we have undertaken an analysis of our accrual. Our analysis assumes that the repurchase liability exposure will decrease over time as mortgage loans are paid off and as we are no longer originating new mortgage loans. We repurchased $0 thousand and $619 thousand of loans during the years ended December 31, 2016 and 2015 , respectively. We review the repurchase reserves throughout the year for adequacy. The following table sets forth information, at December 31, 2016 and 2015 , with respect to our reserves: 2016 2015 Beginning balance $ 314 $ 381 Provision for repurchases (60 ) (1 ) Settlements — (66 ) Total repurchases reserve $ 254 $ 314 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 December 31, 2016 and 2015 , we were committed to fund certain loans including letters of credit amounting to approximately $317 million and $193 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 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 and $275 thousand at December 31, 2016 and 2015 , 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 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. 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. 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 has authorized a potential enforcement action against the Bank. We are in discussions with the U.S. Department of Justice to settle this matter. While we believe that we have meritorious defenses against any potential claim, the ultimate resolution of the matter is unknown. Based on current knowledge, however, we believe that the amount or range of loss with respect to this matter will not have a material impact to our consolidated financial position, results of operations or cash flows. Based on our evaluation of the remaining lawsuits and other proceedings that were pending against us as of December 31, 2016 , 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.

A failure to meet minimum capital requirements is likely to lead to the imposition by federal and state regulators of (i) certain requirements, such as an order requiring additional capital to be raised, and (ii) operational restrictions that could have a direct and material adverse effect on operating results. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios (set forth in the following table) of total capital, common equity Tier 1 capital and Tier I capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier I capital (as defined) to average assets (as defined). We believe that, as of December 31, 2016 , the Company and the Bank met all capital adequacy requirements to which they are subject and have not been notified by any regulatory agency that would require the Company or the Bank to maintain additional capital. The actual capital amounts and ratios of the Company and the Bank at December 31, 2016 and December 31, 2015 are presented in the following tables: Applicable Federal Regulatory Requirement At December 31, 2016 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: Company $ 131,043 12.8 % $ 88,230 At least 8.625 N/A N/A Bank 114,412 11.4 % 86,566 At least 8.625 $ 100,366 At least 10.0 Common Equity Tier 1 Capital to Risk Weighted Assets: Company 101,199 9.9 % 52,427 At least 5.125 N/A N/A Bank 101,807 10.1 % 51,438 At least 5.125 65,238 At least 6.5 Tier 1 Capital to Risk Weighted Assets: Company $ 118,199 11.6 % $ 67,771 At least 6.625 N/A N/A Bank 101,807 10.1 % 66,492 At least 6.625 $ 80,293 At least 8.0 Tier 1 Capital to Average Assets: Company $ 118,199 10.5 % $ 44,923 At least 4.0 N/A N/A Bank 101,807 9.2 % 44,360 At least 4.0 $ 55,450 At least 5.0 Applicable Federal Regulatory Requirement At December 31, 2015 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: Company $ 154,884 16.8 % $ 73,871 At least 8.0 N/A N/A Bank 136,457 15.0 % 72,672 At least 8.0 $ 90,841 At least 10.0 Common Equity Tier 1 Capital to Risk Weighted Assets: Company 131,188 14.2 % 41,552 At least 4.5 N/A N/A Bank 125,018 13.8 % 40,878 At least 4.5 59,046 At least 6.5 Tier 1 Capital to Risk Weighted Assets: Company $ 143,260 15.5 % $ 55,403 At least 6.0 N/A N/A Bank 125,018 13.8 % 54,504 At least 6.0 $ 72,672 At least 8.0 Tier 1 Capital to Average Assets: Company $ 143,260 13.3 % $ 42,984 At least 4.0 N/A N/A Bank 125,018 11.8 % 42,319 At least 4.0 $ 52,899 At least 5.0 As the above tables indicate, at December 31, 2016 and 2015 , the Bank (on a stand-alone basis) qualified as a “well—capitalized” institution, and the capital ratios of the Company (on a consolidated basis) exceeded the capital ratios mandated for bank holding companies, under federally mandated capital standards and federally established prompt corrective action regulations. Since December 31, 2016 , there have been no events or circumstances known to us which have changed or which are expected to result in a change in the Company’s or the Bank’s classification as well-capitalized institutions. 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, 2016 the Bank (on a stand-alone basis) continued to qualify as a well-capitalized institution, and the Company continued to exceed the minimum required capital ratios applicable to it, 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 small and medium-size 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. We also have one non-reportable segment, discontinued operations, which is comprised of our mortgage banking business. Our mortgage banking business originated mortgage loans that, for the most part, were resold within 30 days to long-term investors in the secondary residential mortgage market. 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 and noninterest income for our commercial banking and discontinued operations segments, respectively, for the years ended December 31, 2016 , 2015 and 2014 .

Significant Accounting Polici27

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
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 reserves 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 years ended December 31, 2016 , 2015 and 2014 include the accounts of PMBC, the Bank and PMAR. All significant intercompany balances and transactions were eliminated in consolidation.
Discontinued Operations	Discontinued Operations The revenues and expenses of our mortgage banking division are reported in the consolidated statements of operations as discontinued operations for all periods presented. In determining whether the revenues and expenses are reported as discontinued operations, we evaluate whether we have any significant continuing involvement in the management of any of the mortgage banking operations. If we were to determine that we had any significant continuing involvement, the revenues and expenses of the respective operations would not be recorded in discontinued operations. As of December 31, 2016 and 2015 , we determined that the mortgage repurchase reserves are a liability of the Bank and are not included within the liabilities of discontinued operations. The repurchase reserves are included within other liabilities of the consolidated statements of financial condition.
Cash and Cash Equivalents	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.
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.
Loan Loss Obligation on Loans Previously Sold	Loan Loss Obligation on Loans Previously Sold Upon a sale of mortgage loans held for sale (“LHFS”) that we have originated, the risk of loss due to default by the borrower is generally transferred to the investor. However, we are required to make certain representations to the purchasers of such loans relating to credit information, loan documentation and collateral. These representations and warranties may extend through the contractual life of the loan. If subsequent to the sale of such a loan, any underwriting deficiencies, borrower fraud or documentation defects are discovered with respect to the loan, we may become obligated to repurchase the loan or indemnify the investors for any losses from borrower defaults if such deficiencies or defects cannot be cured within the specified cure periods following their discovery. The obligation for losses attributable to any erroneous representations and warranties or other deficiencies or defects is recorded at its estimate of expected future losses using historical and projected loss frequency and loss severity ratios to estimate our exposure to such losses. In the case of early loan payoffs and early defaults on certain loans, we may be required to repay all or a portion of any premium initially paid by the purchaser of the loan at the time of sale. The obligations associated with early loan payoffs and early defaults on mortgage loans are estimated on the basis of historical loss experience by type of loan.
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 and $275,000 at December 31, 2016 and 2015 , respectively. 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 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	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 Subsidiaries Investment 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 to seven years 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 , 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 estimated 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. Forfeitures are required to be estimated at the time of the grant of options or other share awards and are revised, if necessary, in subsequent periods if actual forfeitures differ from those earlier estimates.
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 Reporting During the years ended December 31, 2016 , 2015 and 2014 , 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 May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606),” which amended its guidance on revenue recognition to conform with international accounting guidance under the International Accounting Standards Board. The ASU provides a framework for addressing revenue recognition and replaces most existing revenue recognition guidance, as well as requires increased disclosure requirements. In August 2015, the FASB issued ASU 2015-14 to defer the effective date of ASU 2014-09 by one year. Accordingly, this guidance is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted for interim and annual periods beginning after December 15, 2016. We will adopt this guidance on January 1, 2018 using the modified retrospective approach. We expect the timing of revenue recognition to be accelerated as a result of the adoption of this guidance because it requires that loan origination fees be recognized at the time of origination, rather than over the life of the loan, which is the current practice. We expect this to create quarterly volatility within interest income as income will fluctuate based on the volume of originations in any given period. In addition, as the duration of our loan portfolio decreases, the impact of the recognition of our loan origination fees will diminish. We do not believe the impact to our beginning retained earnings will be material. In June 2014, the FASB issued ASU 2014-11, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period,” which amended its guidance on how to account for certain performance related share-based compensation plans. The amendments clarify the guidance on how to account for performance based awards when the requisite service period is met prior to potential performance targets being achieved. This guidance is effective for interim and annual periods beginning after December 15, 2015. Early adoption is permitted. We adopted this guidance on January 1, 2016 and it did not have a material effect on our consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements — Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern,” which defines management's responsibility to evaluate whether there is substantial doubt about an organization's ability to continue as a going concern and clarifies when to provide related footnote disclosure. This guidance is effective for interim and annual periods beginning after December 15, 2016. Early adoption is permitted. We adopted this guidance on January 1, 2017 and it had no effect on our consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis,” amends the guidance for assessing how relationships of related parties affect the consolidation analysis, eliminates the presumption that a general partner should consolidate a limited partnership, eliminates the consolidation model specific to limited partnerships, clarifies when fees paid to a decision maker should be a factor in consolidation of a variable interest entity, and reduces the number of variable interest entity consolidation models. This guidance is effective for interim and annual periods beginning after December 15, 2015. Early adoption is permitted. We adopted this guidance on January 1, 2016 and it did not have an impact on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs,” which requires that the debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. This simplifies the presentation of debt issuance costs and makes the presentation consistent with the presentation of debt discounts. This guidance is effective for interim and annual periods beginning after December 15, 2015. Early adoption is permitted. We adopted this guidance on January 1, 2016 and it did not have a material impact on our consolidated financial statements. In August 2015, the FASB issued ASU 2015-15, “Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements — Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting,” which clarifies the accounting for debt issuance costs for line-of-credit arrangements. We adopted this guidance on January 1, 2016 and it did not have a material impact on our consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,” which enhances the reporting model for financial instruments to provide users of financial statements with more useful information. Some of the provisions include: requiring equity investments to be measured at fair value with changes in fair value recognized in net income, simplifying the impairment assessment of equity investments without readily determinable fair values, eliminating the requirement to disclose the method and significant assumptions used to estimate fair value on financial instruments measured at amortized cost on the balance sheet, requiring public business entities to use the exit price notion when measuring the fair value of financial instruments, requiring the reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the organization has elected to measure the liability at fair value in accordance with the fair value option, requiring separate presentation of financial assets and liabilities by measurement category and form of financial asset on the balance sheet or notes to the financial statements, and clarifying that the reporting organization should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the organization's other deferred tax assets. This guidance is effective for interim and annual periods beginning after December 15, 2017. Early adoption is not permitted for public companies. We will adopt this guidance on January 1, 2018. We do not expect adoption of this guidance to have a material impact on our consolidated financial statements as we only have one available-for-sale equity investment where the change in fair value will be recognized in net income, as compared to the current practice of flowing through other comprehensive income. In February 2016, the FASB issued 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. Under the new guidance, lessor accounting is largely unchanged and the accounting for sale and leaseback transactions were simplified. This guidance is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. We will adopt this guidance on January 1, 2019. We expect our statement of financial condition to be grossed up on both the asset and liability side to reflect our lease obligations, and we do not expect adoption of this guidance to have a material impact on our other consolidated financial statements or on our disclosures related to leases. In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting,” which simplifies how several aspects of share-based payments are accounted for and presented in the financial statements. Under the new guidance, some of the aspects that are simplified include: income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This guidance is effective for interim and annual periods beginning after December 15, 2016. Early adoption is permitted. We adopted this guidance on January 1, 2017. As of December 31, 2016, we have excess tax benefits of approximately $211 thousand for which a benefit could not be previously recognized. Upon adoption, the balance of the unrecognized excess tax benefits will be reversed with the impact recorded to retained earnings including any change to the valuation allowance as a result of the adoption. Due to the full valuation allowance on the deferred tax assets, we do not expect any impact to our consolidated financial statements as a result of this adoption. Upon adoption of this guidance, we will elect to recognize forfeitures as they occur instead of applying an estimated forfeiture rate to each grant, which is the current practice. The expected impact to our beginning retained earnings is not expected to be material. On a prospective basis, we expect this could create quarterly volatility in our noninterest expense as forfeitures occur. 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. This guidance is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted for interim and annual periods beginning after December 15, 2018. We will adopt this guidance on January 1, 2020 and expect that it will have a material impact on the determination of our ALLL and an increased ALLL. We are unable to estimate the expected impact to the ALLL upon adoption due to various factors, primarily the 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 gathering the supplemental data needed 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 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which provides guidance for classification of specific items on the statement of cash flows. This guidance is effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted. We will adopt this guidance on January 1, 2018 and do not expect it to have a material impact on our statement of cash flows. In January 2017, the FASB issued ASU 2017-03, “Accounting Changes and Error Corrections (Topic 250) and Investments - Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 16, 2016 EITF Meetings,” which incorporates into FASB accounting standards recent SEC guidance requiring expanded disclosure on the effect of implementation in advance of a company's adoption of a new accounting standard, specifically those related to revenue recognition, leases, financial instruments and credit losses. This guidance is effective immediately. We adopted this guidance upon the date of issuance and have increased the disclosure of the effect of recently issued accounting standards on future periods in this Form 10-K. We will continue to provide expanded disclosure and updates on the estimated effect of recently issued accounting guidance through the period of adoption. This guidance only affected the financial statement footnote disclosures and had no impact on the financial statements.
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.
Measurement Methodology	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 customer 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 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, 2016 , we purchased $0 thousand in value of FHLB stock and no shares of FRBSF stock. 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, U.S. Treasury securities that are traded by dealers or brokers in active over-the- counter markets and money market funds. 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. 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 discounted value of future cash flows expected to be received by the various homogeneous categories of loans. All loans have been adjusted to reflect changes in credit risk. 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. We typically classify our loans held for investment in Level 3 of the fair value hierarchy. 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. 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. We typically classify our noninterest bearing deposits in Level 1 and all remaining deposits in Level 2 of the fair value hierarchy. 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.
