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 in Orange, Los Angeles, San Bernardino and San Diego counties in Southern California and is subject to competition from 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 up to the maximum amount allowed by law. PM Asset Resolution, Inc. ("PMAR") is a wholly owned subsidiary of PMBC which exists for the purpose of purchasing certain non-performing loans and other real estate from the Bank and thereafter collecting on or disposing of those assets. During the fourth quarter of 2013, the Bank announced the closure of our mortgage banking business, which was completed during 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 consolidated 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 Except as discussed below, our accounting policies are described in Note 2, Significant Accounting Policies of our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014 (“Form 10-K”). Interim Consolidated Financial Statements Basis of Presentation Our interim consolidated financial statements are prepared in accordance with generally accepted accounting principles in effect in the United States (“GAAP”) for interim financial information pursuant to rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”), including instructions to Form 10-Q and Article 10 of Regulation S-X, on a basis consistent with prior periods. Our financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of the results for the interim periods presented. The interim results are not necessarily indicative of operating results for the full year. The interim information should be read in conjunction with our audited consolidated financial statements in our Form 10-K. Use of Estimates The preparation of the financial statements in conformity with GAAP requires us to make certain estimates and assumptions that could affect the reported amounts of certain of our assets, liabilities, and contingencies at the date of the financial statements and the reported amounts of our revenues and expenses during the reporting periods. For the fiscal periods covered by this report, those estimates related primarily to our determinations of the allowance for loan and lease losses (“ALLL”), other real estate owned (“OREO”), the fair values of securities available for sale, repurchase reserves, and the determination of the valuation allowance pertaining to deferred tax assets. If circumstances or financial trends on which those estimates were based were to change in the future or there were to occur any currently unanticipated events affecting the amounts of those estimates, our future financial position or results of operations could differ, possibly materially, from those expected at the current time. Principles of Consolidation Our consolidated financial statements for the three and nine months ended September 30, 2015 and 2014 include the accounts of PMBC, the Bank and PMAR. All significant intercompany balances and transactions were eliminated in consolidation. Recent Accounting Pronouncements In February 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-04, “Receivables — Troubled Debt Restructurings by Creditors (Subtopic 310-40) — Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure,” which amended its guidance to clarify when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate recognized. This guidance is effective for interim and annual periods beginning after December 15, 2014. Early adoption is permitted. We adopted this guidance on January 1, 2015 and it did not have a material effect on our consolidated financial statements. In April 2014, the FASB issued ASU 2014-08, “ Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,” which amended its guidance on classification and reporting of discontinued operations. The amendments clarify when an entity should classify a component as discontinued operations, how to report the balances related to discontinued operations for prior periods, and additional disclosure requirements for discontinued operations. This guidance is effective for interim and annual periods beginning after December 15, 2014. Early adoption is permitted only for disposals which have not been previously reported. We adopted this guidance on January 1, 2015 and it did not have a material effect on our consolidated financial statements. In May 2014, the FASB issued 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. We are currently evaluating the expected impact on our consolidated financial statements. 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 will adopt this guidance on January 1, 2016 and do not expect it to 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 will adopt this guidance on January 1, 2017 and do not expect it to have a material effect on our consolidated financial statements. In January 2015, the FASB issued ASU 2015-01, “Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items,” which eliminated the concept of extraordinary items from GAAP. 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, 2015 and it did not have an impact 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 will adopt this guidance on January 1, 2016 and do not expect it to 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 will adopt this guidance on January 1, 2016 and do not expect it to 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 will adopt this guidance on January 1, 2016 and do not expect it to have a material impact on our consolidated financial statements.

Fair Value Measurements

Fair Value Measurements	9 Months Ended
	Sep. 30, 2015
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Under FASB Accounting Standards Codification (“ASC”) 820-10, we group assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: Level 1 Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2 Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. Risks with Fair Value Measurements Fair value estimates are made at a discrete point in time based on relevant market information and other information about the financial instruments. Because no active market exists for a significant portion of our financial instruments, fair value estimates are based in large part on judgments we make primarily regarding current economic conditions, risk characteristics of various financial instruments, prepayment rates, and future expected loss experience. These estimates are subjective in nature and invariably involve some inherent uncertainties. Additionally, the occurrence of unexpected events or changes in circumstances can occur that could require us to make changes to our assumptions and which, in turn, could significantly affect and require us to make changes to our previous estimates of fair value. In addition, the fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of existing and anticipated future customer relationships and the value of assets and liabilities that are not considered financial instruments, such as premises and equipment and OREO. Measurement Methodology Cash and Cash Equivalents. The fair value of cash and cash equivalents approximates its carrying value. Interest-Bearing Deposits with Financial Institutions. The fair values of interest-bearing deposits maturing within one year approximate their carrying values. FHLB and FRBSF Stock. The Bank is a member of the Federal Home Loan Bank of San Francisco (“FHLB”) and the FRBSF. As members, we are required to own stock of the FHLB and the FRBSF, the amount of which is based primarily on the level of our borrowings from those institutions. We also have the right to acquire additional shares of stock in either or both of the FHLB and the FRBSF. During the three and nine months ended September 30, 2015 , we purchased $0 and $33 thousand , respectively, 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. 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. 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. 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. 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.

Investments	Investments Securities Available For Sale, at Fair Value The following table sets forth the major components of securities available for sale and compares the amortized costs and estimated fair market values of, and the gross unrealized gains and losses on, these securities at September 30, 2015 and December 31, 2014 : (Dollars in thousands) September 30, 2015 December 31, 2014 Amortized Cost Gross Unrealized Estimated Fair Value Amortized Cost Gross Unrealized Estimated Fair Value Gain Loss Gain Loss Securities Available for Sale Residential mortgage backed securities issued by U.S. Agencies (1) $ 48,065 $ 72 $ (529 ) $ 47,608 $ 54,653 $ 26 $ (940 ) $ 53,739 Residential collateralized mortgage obligations issued by non agencies (1) 686 — (15 ) 671 790 — (13 ) 777 Asset backed security (2) 2,040 — (599 ) 1,441 2,083 — (433 ) 1,650 Mutual funds (3) 4,750 60 (24 ) 4,786 4,750 45 (35 ) 4,760 Total $ 55,541 $ 132 $ (1,167 ) $ 54,506 $ 62,276 $ 71 $ (1,421 ) $ 60,926 (1) Secured by closed-end first liens on 1-4 family residential mortgages. (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 liens on 1-4 family residential mortgages. At September 30, 2015 , U.S. agency mortgage backed securities with an aggregate fair market value of $2.9 million were pledged to secure repurchase agreements, local agency deposits and treasury, tax and loan accounts. At December 31, 2014 , U.S. agency mortgage backed securities and collateralized mortgage obligations with an aggregate fair market value of $3.6 million were pledged to secure repurchase agreements, local agency deposits and treasury, tax and loan accounts. The amortized cost and estimated fair values of securities available for sale at September 30, 2015 and December 31, 2014 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 September 30, 2015 and December 31, 2014 , the gross unrealized losses and fair values of our investments, aggregated by investment category, and length of time that the individual securities have been in a continuous unrealized loss position.

We have determined that declines in the fair values of these investments below their respective amortized costs, as set forth in the tables above, are temporary because (i) those declines were due to interest rate changes and not to a deterioration in the creditworthiness of the issuers of those investment securities, and (ii) we have the ability to hold those securities until there is a recovery in their values or until their maturity. We recognize other-than-temporary impairments (“OTTI”) to our available-for-sale debt securities in accordance with FASB ASC 320-10. When there are credit losses associated with, but we have no intention to sell, an impaired debt security, and it is more likely than not that we will not have to sell the security before recovery of its cost basis, we will separate the amount of impairment, or OTTI, between the amount that is credit related and the amount that is related to non-credit factors. Credit-related impairments are recognized in our consolidated statements of operations. Any non-credit-related impairments are recognized and reflected in other comprehensive income (loss) in our consolidated statements of financial condition. Through the impairment assessment process, we determined that the available-for-sale securities discussed below were other-than-temporarily impaired at September 30, 2015 . We recorded no impairment credit losses on available-for-sale securities in our consolidated statements of operations for the three and nine months ended September 30, 2015 and 2014 . The OTTI related to factors other than credit losses, in the aggregate amount of $599 thousand , and was recognized as other comprehensive loss in our accompanying consolidated statement of financial condition as of September 30, 2015 . The table below presents, for the nine months ended September 30, 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 ) Change in market value on a security for which an OTTI was previously recognized (205 ) (205 ) — Principal received on OTTI security 39 39 — Balance – September 30, 2015 $ (1,152 ) $ (599 ) $ (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 available 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 available for sale that was impaired as of September 30, 2015 . 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 September 30, 2015 , the amortized cost of this security was $2.0 million with a fair value of $1.4 million , for an unrealized loss of approximately $599 thousand . As of September 30, 2015 , 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 $12.0 million in deferring securities ( 3.5% of total current collateral) from issuance to September 30, 2015 . As of September 30, 2015 , the mezzanine class B tranche had $53.4 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 September 30, 2015 are not other-than-temporarily impaired, because we have concluded that we have the ability to continue to hold those securities until their respective fair market values increase above their respective amortized costs or, if necessary, until their respective maturities. In reaching that conclusion we considered a number of factors and other information, which included: (i) the significance of each such security, (ii) the amount of the unrealized losses attributable to each such security, (iii) our liquidity position, (iv) the impact that retention of those securities could have on our capital position and (v) our evaluation of the expected future performance of these securities (based on the criteria discussed above). Other Investments As of December 31, 2014 , we had one investment in a limited partnership which was accounted for under the equity method of accounting and included within other assets on the consolidated statements of financial condition. During the nine months ended September 30, 2015 , we redeemed 100% of our investment in the limited partnership for a return of capital of $2.1 million . As of September 30, 2015 and December 31, 2014 , our other investment was as follows: September 30, 2015 December 31, 2014 (Dollars in thousands) Investment accounted for under the equity method $ — $ 2,081

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 a certain number of 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 September 30, 2015 or December 31, 2014 . 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 (referred to as full nonaccrual basis of accounting), except when the ultimate collectability of principal is probable, in which case such payments are applied to accrued and unpaid interest, which is credited to income (referred to as nonaccrual cash basis of accounting). Non-accrual loans may be restored to accrual status when principal and interest become current and full repayment becomes expected. The following table provides information with respect to loans on nonaccrual status, by portfolio type, as of September 30, 2015 and December 31, 2014 : September 30, 2015 December 31, 2014 (Dollars in thousands) Nonaccrual loans: Commercial loans $ 12,149 $ 16,182 Commercial real estate loans – owner occupied 1,640 2,171 Commercial real estate loans – all other 2,642 2,117 Residential mortgage loans – multi-family 449 — Residential mortgage loans – single family 706 1,472 Land development loans 1,640 2,111 Total (1) $ 19,226 $ 24,053 (1) Nonaccrual loans may include loans that are currently considered performing loans.

We measure for impairments on a loan-by-loan basis, using either the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral if the loan is collateral dependent.

This typically occurs when the impaired loans have been partially charged-off and/or there have been interest payments received and applied to the balance of the principal outstanding. At September 30, 2015 and December 31, 2014 , there were $25.3 million and $32.6 million , respectively, of impaired loans for which no specific reserves had been allocated because these loans, in our judgment, were sufficiently collateralized. Of the impaired loans at September 30, 2015 for which no specific reserves were allocated, $20.4 million had been deemed impaired in the prior year.

The interest that would have been earned had the impaired loans remained current in accordance with their original terms was $683 thousand and $351 thousand during the nine months ended September 30, 2015 and 2014 , respectively. Troubled Debt Restructurings (“TDRs”) Pursuant to the FASB's ASU No. 2011-2, A Creditor's Determination of whether a Restructuring is a Troubled Debt Restructuring , the Bank's TDRs totaled $21.8 million and $17.0 million at September 30, 2015 and December 31, 2014 , 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 $21.8 million of TDRs outstanding at September 30, 2015 , $7.7 million were performing in accordance with their terms and accruing interest, and $14.1 million were not. Our impairment analysis determined no specific reserves were required on the TDR balances outstanding at September 30, 2015 .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three and nine months ended September 30, 2015 and September 30, 2014 , we recorded no income tax provision. Our net deferred tax asset at September 30, 2015 was $5.8 million , net of a valuation allowance of $10.8 million . Based on the analysis performed, and the positive and negative evidence considered, management determined that no increase in the $10.8 million valuation allowance as of September 30, 2015 was needed. Positive evidence included our current period taxable income, improvement in asset quality, tax planning strategies, and economic conditions. Negative evidence included historical losses over the previous 12 quarter look back period and our accumulated deficit. Management concluded that it was more-likely-than-not that the existing $5.8 million net deferred tax asset would be realized. Our net deferred tax asset at September 30, 2014 was $6.2 million , net of a valuation allowance of $12.2 million . Based on the analysis performed, and the positive and negative evidence considered, management chose not to release any portion of the $12.2 million valuation allowance as of September 30, 2014. Positive evidence included improvement in our asset quality, tax planning strategies, and economic conditions. Negative evidence included historical operating losses and our accumulated deficit. Management determined the negative evidence was significant enough to outweigh the positive evidence and support no reversal of the valuation allowance; however, we did conclude that it was more-likely-than-not that the existing $6.2 million net deferred tax asset at the time would be realized. We file income tax returns with the U.S. federal government and the state of California. As of September 30, 2015, we were subject to examination by the Internal Revenue Service with respect to our U.S. federal tax returns for the 2011 to 2013 tax years and Franchise Tax Board for California state income tax returns for the 2010 to 2013 tax years. Net operating losses (“NOLs”) on our U.S. federal and California state income tax returns may be carried forward twenty years. As of September 30, 2015, 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 three and nine months ended September 30, 2015 and 2014.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Employee Compensation Plans	Stock-Based Employee Compensation Plans In May 2010, our shareholders approved the adoption of our 2010 Equity Incentive Plan (the “2010 Incentive Plan”), which authorized and set aside a total of 400,000 shares of our common stock for issuance on the exercise of stock options or the grant of restricted stock or other equity incentives to our officers, and other key employees and directors. 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 483,386 shares of our common stock granted under the Previously Approved Plans were outstanding at September 30, 2015 . 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 95,000 shares of restricted stock, net of shares withheld for taxes, have vested as of September 30, 2015 thereby decreasing the maximum number of shares authorized under the 2010 Incentive Plan. As a result, as of September 30, 2015 , the maximum number of shares that were authorized for the grant of options or other equity incentives under the 2010 Incentive Plan totaled 1,759,948 (assuming that all 483,386 shares of our common stock subject to options under the Previously Approved Plans expire or are terminated), or approximately 8% 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 September 30, 2015 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 and directors. These restricted shares vest over a period of three years for employees and one year for directors. 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.

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 three and nine months ended September 30, 2015 and 2014 .

(2) Convertible securities were excluded from the computation of diluted earnings per common share for the three and nine months ended September 30, 2014 as we reported a net loss from continuing operations. (3) Stock purchase warrants were excluded from the computation of diluted earnings per common share for the three and nine months ended September 30, 2014 because the exercisability of those warrants was conditioned on the happening of certain future events.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies 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 $619 thousand of loans during the nine months ended September 30, 2015 . We repurchased $1.3 million of loans during the nine months ended September 30, 2014 . No loans were repurchased during the three months ended September 30, 2015 and September 30, 2014 . The following table sets forth information at September 30, 2015 and December 31, 2014 , with respect to our repurchase reserves: At and For the Nine Months Ended At and For the Year Ended September 30, 2015 December 31, 2014 (Dollars in thousands) Beginning balance $ 381 $ 1,883 (Recovery of)/Provision for repurchases 13 (1,502 ) Settlements (66 ) — Total repurchases reserve $ 328 $ 381 Commitments To meet the financing needs of our customers in the normal course of business, we are a party to financial instruments with off-balance sheet risk. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated financial statements. At September 30, 2015 and December 31, 2014 , we were committed to fund certain loans including letters of credit amounting to approximately $226 million and $148 million , respectively. The contractual amounts of a credit-related financial instrument, such as a commitment to extend credit, a credit-card arrangement or a letter of credit, represent the amount of potential accounting loss should the commitment be fully drawn upon, the customer were to default, and the value of any existing collateral securing the customer’s payment obligation becomes worthless. The loss reserve for unfunded loan commitments was $275 thousand at each of September 30, 2015 and December 31, 2014 . 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. 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 assess the likelihood of any loss or exposure with respect to lawsuits and other proceedings that are pending against us. We establish an accrued liability for lawsuits or other legal proceedings when they present loss contingencies that are both probable and estimable. Where a loss is not probable but it is reasonably possible or where a loss in excess of an amount accrued is reasonably possible, we disclose an estimate of the amount of the loss or range of possible losses for the claim if a reasonable estimate can be made, unless the amount of reasonably possible losses with respect to the matter is not material to our financial condition, results of operations or cash flows. We estimate any potential loss based upon currently available information and significant judgments and a variety of assumptions, and known and unknown uncertainties. Moreover, the facts and circumstances on which such estimates are based will change over time. Therefore, the amount of any losses we might incur in any lawsuits or other legal proceedings may exceed amounts which we had accrued based on our estimates and those estimates do not represent the maximum loss exposure that we may have in connection with any lawsuits or other legal proceedings. Based on our evaluation of the lawsuits and other proceedings that were pending against us as of September 30, 2015 , 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 financial position, results of operations or cash flows for any particular reporting period.

Business Segment Information

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, as well as our discontinued operations, are reported below using net interest income (interest income less interest expense) and noninterest income (primarily net gains on sales of SBA 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 three and nine months ended September 30, 2015 and 2014 .

Regulatory Capital Requirements [Abstract]
Regulatory Capital	Regulatory Capital Under federal banking regulations that apply to all United States based bank holding companies and federally insured banks, the Company (on a consolidated basis) and the Bank (on a stand-alone basis) must meet specific capital adequacy requirements that, for the most part, involve quantitative measures, primarily in terms of the ratios of their capital to their assets, liabilities, and certain off-balance sheet items, calculated under regulatory accounting practices. Under those regulations, each bank holding company must meet a minimum capital ratio and each federally insured bank is determined by its primary federal bank regulatory agency to come within one of the following capital adequacy categories on the basis of its capital ratios: • well capitalized • adequately capitalized • undercapitalized • significantly undercapitalized; or • critically undercapitalized Certain qualitative assessments also are made by a banking institution’s primary federal regulatory agency that could lead the agency to determine that the banking institution should be assigned to a lower capital category than the one indicated by the quantitative measures used to assess the institution’s capital adequacy. At each successive lower capital category, a banking institution is subject to greater operating restrictions and increased regulatory supervision by its federal bank regulatory agency. The following table sets forth the capital and capital ratios of the Company (on a consolidated basis) and the Bank (on a stand-alone basis) at September 30, 2015 , as compared to the respective regulatory requirements applicable to them. Applicable Federal Regulatory Requirement For Capital Adequacy Purposes To be Categorized As Well Capital Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) Total Capital to Risk Weighted Assets: Company $ 147,535 17.0 % $ 69,641 At least 8.0 N/A N/A Bank 128,943 14.7 % 70,024 At least 8.0 $ 87,530 At least 10.0 Common Equity Tier 1 Capital to Risk Weighted Assets: Company $ 121,084 13.9 % $ 39,173 At least 4.5 N/A N/A Bank 117,943 13.5 % 39,389 At least 4.5 $ 56,895 At least 6.5 Tier 1 Capital to Risk Weighted Assets: Company $ 136,595 15.7 % $ 52,231 At least 6.0 N/A N/A Bank 117,943 13.5 % 52,518 At least 6.0 $ 70,024 At least 8.0 Tier 1 Capital to Average Assets: Company $ 136,595 12.8 % $ 42,556 At least 4.0 N/A N/A Bank 117,943 11.2 % 42,092 At least 4.0 $ 52,615 At least 5.0 In early July 2013, the Federal Reserve Board and the FDIC issued final rules implementing the Basel III regulatory capital framework and related Dodd-Frank Wall Street Reform and Consumer Protection Act changes. The rules revise minimum capital requirements and adjust prompt correct action thresholds. The final rules revise the regulatory capital elements, add a new common equity Tier 1 capital ratio, increase the minimum Tier 1 capital ratio requirement, and implement a new capital conservation buffer. The rules also permit certain banking organizations to retain, through a one-time election, the existing treatment for accumulated other comprehensive income. The final rules took effect for community banks on January 1, 2015, subject to a transition period for certain parts of the rules. At September 30, 2015 , 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.

Accounting Policies [Abstract]
Interim Consolidated Financial Statements Basis of Presentation	Interim Consolidated Financial Statements Basis of Presentation Our interim consolidated financial statements are prepared in accordance with generally accepted accounting principles in effect in the United States (“GAAP”) for interim financial information pursuant to rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”), including instructions to Form 10-Q and Article 10 of Regulation S-X, on a basis consistent with prior periods. Our financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of the results for the interim periods presented. The interim results are not necessarily indicative of operating results for the full year. The interim information should be read in conjunction with our audited consolidated financial statements in our Form 10-K.
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with GAAP requires us to make certain estimates and assumptions that could affect the reported amounts of certain of our assets, liabilities, and contingencies at the date of the financial statements and the reported amounts of our revenues and expenses during the reporting periods. For the fiscal periods covered by this report, those estimates related primarily to our determinations of the allowance for loan and lease losses (“ALLL”), other real estate owned (“OREO”), the fair values of securities available for sale, repurchase reserves, and the determination of the valuation allowance pertaining to deferred tax assets. If circumstances or financial trends on which those estimates were based were to change in the future or there were to occur any currently unanticipated events affecting the amounts of those estimates, our future financial position or results of operations could differ, possibly materially, from those expected at the current time.
Principles of Consolidation	Principles of Consolidation Our consolidated financial statements for the three and nine months ended September 30, 2015 and 2014 include the accounts of PMBC, the Bank and PMAR. All significant intercompany balances and transactions were eliminated in consolidation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-04, “Receivables — Troubled Debt Restructurings by Creditors (Subtopic 310-40) — Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure,” which amended its guidance to clarify when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate recognized. This guidance is effective for interim and annual periods beginning after December 15, 2014. Early adoption is permitted. We adopted this guidance on January 1, 2015 and it did not have a material effect on our consolidated financial statements. In April 2014, the FASB issued ASU 2014-08, “ Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,” which amended its guidance on classification and reporting of discontinued operations. The amendments clarify when an entity should classify a component as discontinued operations, how to report the balances related to discontinued operations for prior periods, and additional disclosure requirements for discontinued operations. This guidance is effective for interim and annual periods beginning after December 15, 2014. Early adoption is permitted only for disposals which have not been previously reported. We adopted this guidance on January 1, 2015 and it did not have a material effect on our consolidated financial statements. In May 2014, the FASB issued 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. We are currently evaluating the expected impact on our consolidated financial statements. 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 will adopt this guidance on January 1, 2016 and do not expect it to 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 will adopt this guidance on January 1, 2017 and do not expect it to have a material effect on our consolidated financial statements. In January 2015, the FASB issued ASU 2015-01, “Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items,” which eliminated the concept of extraordinary items from GAAP. 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, 2015 and it did not have an impact 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 will adopt this guidance on January 1, 2016 and do not expect it to 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 will adopt this guidance on January 1, 2016 and do not expect it to 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 will adopt this guidance on January 1, 2016 and do not expect it to have a material impact on our consolidated financial statements.
