Accounting Policies [Abstract]
Basis of Financial Statement Presentation	Note 1 - Basis of Financial Statement Presentation CU Bancorp (the “Company”) is a bank holding company whose operating subsidiary is California United Bank. As a bank holding company, CU Bancorp is subject to regulation of the Federal Reserve Board (“FRB”). The term “Company”, as used throughout this document, refers to the consolidated financial statements of CU Bancorp and California United Bank. California United Bank (the “Bank”) is a full-service commercial business bank offering a broad range of banking products and services including: deposit services, lending and cash management to small and medium-sized businesses, to non-profit organizations, to business principals and entrepreneurs, to the professional community, including attorneys, certified public accountants, financial advisors, healthcare providers and investors. The Bank opened for business in 2005. Its current headquarters office is located in Los Angeles, California. As a state chartered non-member bank, the Bank is subject to regulation by the California Department of Business Oversight (“DBO”) and the Federal Deposit Insurance Corporation (“FDIC”). The deposits of the Bank are insured by the FDIC to the maximum amount allowed by law. The consolidated financial statements include the accounts of the Company and the Bank. Significant intercompany items have been eliminated in consolidation. The accounting and reporting policies of the Company conform to U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). CU Bancorp is the common shareholder of Premier Commercial Statutory Trust I, Premier Commercial Statutory Trust II, and Premier Commercial Statutory Trust III, entities which were acquired in the merger with Premier Commercial Bancorp (“PC Bancorp”). These trusts were established for the sole purpose of issuing trust preferred securities and do not meet the criteria for consolidation. For more detail, see Note 8 – Borrowings and Subordinated Debentures. Certain information and footnote disclosures presented in the annual consolidated financial statements are not included in the interim consolidated financial statements. Accordingly, the accompanying unaudited interim consolidated financial statements should be read in conjunction with the 2015 Annual Report on Form 10-K. In the opinion of management, the accompanying interim consolidated financial statements contain all necessary adjustments of a normal recurring nature, to present fairly the consolidated financial position of the Company and the results of its operations for the interim periods presented. Use of Estimates in the Preparation of Consolidated Financial Statements The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In addition, these accounting principles require the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements. Estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan loss and various assets and liabilities measured at fair value. While management uses the most current available information to recognize losses on loans, future additions to the allowance for loan loss may be necessary based on, among other factors, changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan loss. Regulatory agencies may require the Company to recognize changes to the allowance for loan loss based on their judgment about information available to them at the time of their examination. Business Segments The Company is organized and operates as a single reporting segment, principally engaged in commercial business banking. The Company conducts its lending and deposit operations through nine full service branch offices located in Los Angeles, Orange, Ventura and San Bernardino counties.

Further, the Company does not intend to sell these securities and is not more-likely-than-not to be required to sell the securities before the recovery of its amortized cost basis. Accordingly, the Company had no securities that were classified as other-than-temporary impaired at March 31, 2016 or December 31, 2015, and did not recognize any impairment charges in the consolidated statements of income. The amortized cost, fair value and the weighted average yield of debt securities at March 31, 2016, are reflected in the table below (dollars in thousands). Maturity categories are determined as follows: • U.S. Govt. Agency, U.S. Treasury Notes and U.S. Govt. Sponsored Agency bonds and notes – maturity date • U.S. Govt. Sponsored Agency CMO or Mortgage-Backed Securities, U.S. Govt. Agency GNMA Mortgage-Backed Securities, Asset Backed Securities and U.S. Gov.

Under the Company’s loan risk rating system, loans are classified as “Pass,” with problem and potential problem loans as “Special Mention,” “Substandard,” “Doubtful” and “Loss”. Individual loan risk ratings are updated continuously or at any time the situation warrants. In addition, management regularly reviews problem loans to determine whether any loan requires a classification change, in accordance with the Company’s policy and applicable regulations. The grading analysis estimates the capability of the borrower to repay the contractual obligations of the loan agreements as scheduled or at all. The internal loan classification risk grading system is based on experiences with similarly graded loans. The Company’s internally assigned grades are as follows: • Pass – loans which are protected by the current net worth and paying capacity of the obligor or by the value of the underlying collateral. There are several different levels of Pass rated credits, including “Watch” which is considered a transitory grade for pass rated loans that require greater monitoring. Loans not meeting the criteria of special mention, substandard, doubtful or loss that have been analyzed individually as part of the above described process are considered to be pass-rated loans. • Special Mention – loans where a potential weakness or risk exists, which could cause a more serious problem if not corrected. Special Mention loans do not currently expose the Company to sufficient risk to warrant classification as a Substandard, Doubtful or Loss classification, but possess weaknesses that deserve management’s close attention. • Substandard – loans that have a well-defined weakness based on objective evidence and can be characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. • Doubtful – loans classified as doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. • Loss – loans classified as a loss are considered uncollectible, or of such value that continuance as an asset is not warranted. The following tables present the risk category of loans by class of loans based on the most recent internal loan classification as of the dates indicated (dollars in thousands): Commercial Industrial Construction, Other Land Commercial Other Real Estate Other Total March 31, 2016 Pass $ 462,898 $ 156,731 $ 1,154,374 $ 34,116 $ 1,808,119 Special Mention 2,648 — 3,084 — 5,732 Substandard 30,755 — 21,614 2,958 55,327 Doubtful — — — — — Total $ 496,301 $ 156,731 $ 1,179,072 $ 37,074 $ 1,869,178 December 31, 2015 Pass $ 503,006 $ 125,832 $ 1,101,548 $ 40,132 $ 1,770,518 Special Mention 16,041 — 6,494 43 22,578 Substandard 18,321 — 18,809 2,937 40,067 Doubtful — — — — — Total $ 537,368 $ 125,832 $ 1,126,851 $ 43,112 $ 1,833,163 Aging Analysis of Past Due and Non-Accrual Loans The following tables present an aging analysis of the recorded investment of past due loans and non-accrual loans as of the dates indicated (dollars in thousands): 31-60 Days Past Due 61-90 Days Past Due Greater 90 Days Past Due and Total Past Due and Total Non Current Total Loans March 31, 2016 Commercial and Industrial $ 9 $ — $ — $ 9 $ 589 $ 495,703 $ 496,301 Construction, Land Development and Other Land — — — — — 156,731 156,731 Commercial and Other Real Estate 800 — — 800 1,226 1,177,046 1,179,072 Other — — — — — 37,074 37,074 Total $ 809 $ — $ — $ 809 $ 1,815 $ 1,866,554 $ 1,869,178 31-60 Days Past Due 61-90 Days Past Due Greater 90 Days Past Due and Total Past Due and Total Non Current Total Loans December 31, 2015 Commercial and Industrial $ — $ — $ — $ — $ 1,032 $ 536,336 $ 537,368 Construction, Land Development and Other Land — — — — — 125,832 125,832 Commercial and Other Real Estate — — — — 1,019 1,125,832 1,126,851 Other — — — — — 43,112 43,112 Total $ — $ — $ — $ — $ 2,051 $ 1,831,112 $ 1,833,163 Impaired Loans Impaired loans are evaluated by comparing the fair value of the collateral, if the loan is collateral dependent, and the present value of the expected future cash flows discounted at the loan’s effective interest rate, if the loan is not collateral dependent. A valuation allowance is established for an impaired loan when the realizable value of the loan is less than the recorded investment. In certain cases, portions of impaired loans are charged-off to realizable value instead of establishing a valuation allowance and are included, when applicable, in the table below as impaired loans “with no specific allowance recorded.” The valuation allowance disclosed below is included in the allowance for loan loss reported in the consolidated balance sheets as of March 31, 2016 and December 31, 2015. The following tables present, by loan portfolio segment, the recorded investment and unpaid principal balances for impaired loans with the associated allowance amount, if applicable, for the dates and periods indicated (dollars in thousands). This table excludes purchased credit impaired loans (loans acquired in acquisitions with deteriorated credit quality) of $1.9 million and $2.0 million at March 31, 2016 and December 31, 2015, respectively.

Loans are restructured in an effort to maximize collections. Economic concessions can include: reductions to the stated interest rate, payment extensions, principal forgiveness or other actions. The modification process includes evaluation of impairment based on the present value of expected future cash flows, discounted at the effective interest rate of the original loan agreement, except when the sole (remaining) source of repayment for the loan is the operation or liquidation of the loan collateral. In these cases, management uses the current fair value of the collateral, less selling costs, to evaluate the loan for impairment. If management determines that the value of the modified loan is less than the recorded investment in the loan (net of previous charge-offs and unamortized premium or discount) impairment is recognized through a specific allowance or a charge-off. The following tables include the recorded investment and unpaid principal balances for troubled debt restructured loans at March 31, 2016 and December 31, 2015. These tables include TDR loans that were purchased credit impaired (“PCI”). TDR loans that are non-PCI loans are included in the Impaired Loans tables above. As of March 31, 2016, there were two PCI loans that are considered to be TDR loans with a recorded investment of $131 thousand and unpaid principal balances of $316 thousand. Recorded Unpaid Interest (Dollars in thousands) As of and for the three months ended March 31, 2016 Commercial and Industrial $ 393 $ 615 $ — Total $ 393 $ 615 $ — Recorded Unpaid Interest As of and for the twelve months ended December 31, 2015 Commercial and Industrial $ 627 $ 1,363 $ — Total $ 627 $ 1,363 $ — Recorded Unpaid Interest As of and for the three months ended March 31, 2015 Commercial and Industrial $ 500 $ 704 $ — Commercial and Other Real Estate 110 112 — Total $ 610 $ 816 $ — There were no loans modified or restructured during the three months ended March 31, 2016 or March 31, 2015. There have been no payment defaults in the three months ended March 31, 2016 or March 31, 2015 subsequent to modification on troubled debt restructured loans that have been modified within the last twelve months. Loans are restructured in an effort to maximize collections. Impairment analyses are performed on the Company’s troubled debt restructured loans in conjunction with the normal allowance for loan loss process. The Company’s troubled debt restructured loans are analyzed to ensure adequate cash flow or collateral supports the outstanding loan balance. There were no commitments to lend additional funds to borrowers whose terms have been modified in troubled debt restructurings at March 31, 2016 and December 31, 2015. Loans Acquired Through Acquisition The following table reflects the accretable net discount for acquired loans for the periods indicated (dollars in thousands): Three Months Ended 2016 2015 Balance, beginning of period $ 14,610 $ 21,402 Accretion, included in interest income (1,133 ) (1,216 ) Reclassifications to non-accretable yield (7 ) (109 ) Balance, end of period $ 13,470 $ 20,077 The above table reflects the fair value adjustment on the loans acquired from mergers that will be amortized to loan interest income based on the effective yield method over the remaining life of the loans. These amounts do not include the fair value adjustments on the purchased credit impaired loans acquired from mergers. Purchased Credit Impaired Loans PCI loans are acquired loans with evidence of deterioration of credit quality since origination and it is probable at the acquisition date, that the Company will not be able to collect all contractually required amounts. When the timing and/or amounts of expected cash flows on such loans are not reasonably estimable, no interest is accreted and the loan is reported as a non-accrual loan; otherwise, if the timing and amounts of expected cash flows for PCI loans are reasonably estimable, then interest is accreted and the loans are reported as accruing loans. The non-accretable difference represents the difference between the undiscounted contractual cash flows and the undiscounted expected cash flows, and also reflects the estimated credit losses in the acquired loan portfolio at the acquisition date and can fluctuate due to changes in expected cash flows during the life of the PCI loans. The following table reflects the outstanding balance and related carrying value of PCI loans as of the dates indicated (dollars in thousands): March 31, 2016 December 31, 2015 Unpaid Carrying Value Unpaid Carrying Value Commercial and Industrial $ 675 $ 335 $ 2,331 $ 477 Commercial and Other Real Estate 2,233 1,532 2,250 1,535 Other — — 61 — Total $ 2,908 $ 1,867 $ 4,642 $ 2,012 The following table reflects the activities in the accretable net discount for PCI loans for the period indicated (dollars in thousands): Three Months Ended 2016 2015 Balance, beginning of period $ 246 $ 324 Accretion, included in interest income (20 ) (19 ) Reclassifications from non-accretable yield — — Balance, end of period $ 226 $ 305

Borrowings and Subordinated Debentures	Note 8 - Borrowings and Subordinated Debentures Securities Sold Under Agreements to Repurchase The Company enters into certain transactions, the legal form of which are sales of securities under agreements to repurchase (“Repos”) at a later date at a set price. Securities sold under agreements to repurchase generally mature within 1 day to 180 days from the issue date and are routinely renewed. As discussed in Note 5 – Investment Securities, the Company has pledged certain investments as collateral for these agreements. Securities with a fair value of $45 million and $47 million were pledged to secure the Repos at March 31, 2016 and December 31, 2015, respectively. The tables below describe the terms and maturity of the Company’s securities sold under agreements to repurchase as of the dates indicated (dollars in thousands): March 31, 2016 Date Issued Amount Interest Rate Original Maturity Date March 31, 2016 $ 21,967 0.125% – 0.25 % 1 day April 01, 2016 Total $ 21,967 0.21 % December 31, 2015 Date Issued Amount Interest Rate Original Maturity Date December 31, 2015 $ 14,360 0.08% – 0.25 % 4 days January 4, 2016 Total $ 14,360 0.19 % FHLB Borrowings The Company maintains a secured credit facility with the FHLB, allowing the Company to borrow on an overnight and term basis. The Company’s credit facility with the FHLB is $659 million, which represents approximately 25% of the Bank’s total assets, as reported by the Bank in its December 31, 2015 Federal Financial Institution Examination Council (FFIEC) Call Report. As of March 31, 2016, the Company had $868 million of loan collateral pledged with the FHLB which provides $576 million in borrowing capacity. The Company has $19 million in investment securities pledged with the FHLB to support this credit facility. In addition, the Company must maintain an investment in the Capital Stock of the FHLB. Under the FHLB Act, the FHLB has a statutory lien on the FHLB capital stock that the Company owns and the FHLB capital stock serves as further collateral under the borrowing line. The Company had no outstanding advances (borrowings) with the FHLB as of March 31, 2016 or December 31, 2015. Subordinated Debentures The following table summarizes the terms of each issuance of subordinated debentures outstanding as of March 31, 2016: Series Amount (in Issuance Maturity Rate Index Current Next Trust I $ 6,186 12/10/04 03/15/35 3 month LIBOR + 2.05 % 2.684 % 06/15/16 Trust II 3,093 12/23/05 03/15/36 3 month LIBOR + 1.75 % 2.384 % 06/15/16 Trust III 3,093 06/30/06 09/18/36 3 month LIBOR + 1.85 % 2.484 % 06/15/16 Subtotal 12,372 Unamortized fair value adjustment (2,635 ) Net $ 9,737 The Company had an aggregate outstanding contractual balance of $12.4 million in subordinated debentures at March 31, 2016. These subordinated debentures were acquired as part of the PC Bancorp merger and were issued to trusts originally established by PC Bancorp, which in turn issued trust preferred securities. These subordinated debentures were issued in three separate series. Each issuance had a maturity of 30 years from their approximate date of issue. All three subordinated debentures are variable rate instruments that reprice quarterly based on the three month LIBOR plus a margin (see tables above). All three subordinated debentures had their interest rates reset in March 2016 at the current three month LIBOR plus their index, and will continue to reprice quarterly through their maturity date. All three subordinated debentures are currently callable at par with no prepayment penalties. Under Dodd Frank, trust preferred securities are excluded from Tier 1 capital, unless such securities were issued prior to May 19, 2010 by a bank holding company with less than $15 billion in assets. CU Bancorp assumed approximately $12.4 million of junior subordinated debt securities issued to various business trust subsidiaries of Premier Commercial Bancorp and funded through the issuance of approximately $12.0 million of floating rate capital trust preferred securities. These junior subordinated debt securities were issued prior to May 19, 2010. Because CU Bancorp has less than $15 billion in assets, the trust preferred securities that CU Bancorp assumed from Premier Commercial Bancorp continue to be included in Tier 1 capital, subject to a limit of 25% of Tier 1 capital elements. Interest payments made by the Company on subordinated debentures are considered dividend payments under FRB regulations. Notification to the FRB is required prior to the Company declaring and paying a dividend during any period in which the Company’s quarterly net earnings are insufficient to fund the dividend amount. This notification requirement is included in regulatory guidance regarding safety and soundness surrounding capital and includes other non-financial measures such as asset quality, financial condition, capital adequacy, liquidity, future earnings projections, capital planning and credit concentrations. Should the FRB object to the dividend payments, the Company would be precluded from paying interest on the subordinated debentures after giving notice within 15 days before the payment date. Payments would not commence until approval is received or the Company no longer needs to provide notice under applicable guidance. The Company has the right, assuming no default has occurred, to defer payments of interest on the subordinated debentures at any time for a period not to exceed 20 consecutive quarters. The Company has not deferred any interest payments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 9 - Derivative Financial Instruments The Company is exposed to certain risks relating to its ongoing business operations and utilizes interest rate swap agreements (“swaps”) as part of its asset/liability management strategy to help manage its interest rate risk position. The Company has two counterparty banks. Derivative Financial Instruments Acquired from 1 st At March 31, 2016, the Company has twelve interest rate swap agreements with customers and twelve offsetting interest-rate swaps with a counterparty bank that were acquired as a result of the merger with 1 st The structure of the swaps is as follows: The Company enters into a swap with its customers to allow them to convert variable rate loans to fixed rate loans, and at the same time, the Company enters into a swap with the counterparty bank to allow the Company to pass on the interest-rate risk associated with fixed rate loans. The net effect of the transaction allows the Company to receive interest on the loan from the customer at a variable rate based on LIBOR plus a spread. The changes in the fair value of the swaps primarily offset each other and therefore should not have a significant impact on the Company’s results of operations. Our interest rate swap derivatives acquired from 1 st The Company believes the risk of loss associated with counterparty borrowers relating to interest rate swaps is mitigated as the loans with swaps are underwritten to take into account potential additional exposure, although there can be no assurances in this regard since the performance of the swaps is subject to market and counterparty risk. At March 31, 2016 and December 31, 2015, the total notional amount of the Company’s swaps with the counterparty bank was $27 million and $28 million, respectively. The following tables present the fair values of the asset and liability of the Company’s derivative instruments acquired from 1 st March 31, 2016 December 31, 2015 Interest rate swap contracts fair value $ 1,503 $ 881 Balance sheet location Accrued Interest Accrued Interest March 31, 2016 December 31, 2015 Interest rate swap contracts fair value $ 1,503 $ 881 Balance sheet location Accrued Interest Accrued Interest Derivative Financial Instruments Acquired from PC Bancorp At March 31, 2016, the Company also has nineteen pay-fixed, receive-variable, interest rate swaps that are designed to convert fixed rate loans into variable rate loans. The Company acquired these interest rate swap contracts on July 31, 2012 as a result of the merger with PC Bancorp. All of the interest rate swap contracts acquired from PC Bancorp are with the same counterparty bank. The outstanding swaps have original maturities of up to 15 years.

Balance Sheet Offsetting	Note 10 – Balance Sheet Offsetting Assets and liabilities relating to certain financial instruments, including derivatives, and securities sold under repurchase agreements (“Repos”), may be eligible for offset in the consolidated balance sheets as permitted under accounting guidance. The Company’s interest rate swap derivatives are subject to a master bilateral netting and offsetting arrangement under specific conditions as defined within a master agreement governing all interest rate swap contracts that the Company and the counterparty banks have entered into. In addition, the master agreement under which the interest rate contracts have been written require the pledging of assets by the Company based on certain risk thresholds. The Company has pledged a certificate of deposit and investment securities as collateral under the swap agreements. The pledged collateral under the swap agreements are reported in the Company’s consolidated balance sheets, unless the Company defaults under the master agreement. The Company currently does not net or offset the interest rate swap contracts in its consolidated balance sheets, as reflected within the table below. The Company’s securities sold under repurchase agreements represent transactions the Company has entered into with several deposit customers. These transactions represent the sale of securities on an overnight or on a term basis to our deposit customers under an agreement to repurchase the securities from the customers the next business day or at maturity. There is an individual contract for each customer with only one transaction per customer. There is no master agreement that provides for the netting arrangement or the offsetting of these individual transactions or for the netting of collateral positions. The Company does not net or offset the Repos in its consolidated balance sheets as reflected within the table below.

Stock Options and Restricted Stock	Note 11 - Stock Options and Restricted Stock Equity Compensation Plans The Company’s 2007 Equity and Incentive Plan (“Equity Plan”) was adopted by the Company in 2007 and replaced two prior equity compensation plans. The Equity Plan provides for significant flexibility in determining the types and terms of awards that may be made to participants. The Equity Plan was revised and approved by the Company’s shareholders in 2011 and adopted by the Company as part of the Bank holding company reorganization. This plan is designed to promote the interest of the Company in aiding the Company to attract and retain employees, officers and non-employee directors who are expected to contribute to the future success of the organization. The Equity Plan is intended to provide participants with incentives to maximize their efforts on behalf of the Company through stock-based awards that provide an opportunity for stock ownership. This plan provides the Company with a flexible equity incentive compensation program, which allows the Company to grant stock options, restricted stock, restricted stock award units and performance units. Certain options and share awards provide for accelerated vesting, if there is a change in control, as defined in the Equity Plan. These plans are described more fully in Note 16 - Stock Options and Restricted Stock in the Company’s Form 10-K for the year ended December 31, 2015. At March 31, 2016, future compensation expense related to unvested restricted stock grants are reflected in the table below (dollars in thousands): Future Restricted Stock Expense Remainder of 2016 $ 2,048 2017 1,034 2018 296 2019 36 Thereafter — Total $ 3,414 At March 31, 2016, the weighted-average period over which the total compensation cost related to unvested restricted stock grants not yet recognized is 1.4 years. There was no future compensation expense related to unvested stock options as of March 31, 2016. All stock options outstanding at March 31, 2016 are vested. Stock Options There were no stock options granted by the Company since 2010. The following table summarizes the share option activity under the plans as of the date and for the period indicated: Shares Weighted Weighted (in years) Aggregate (in thousands) Outstanding stock options at December 31, 2015 557,471 $ 10.57 0.8 $ 8,248 Granted — Exercised (189,489 ) Forfeited — Expired — Outstanding stock options at March 31, 2016 367,982 $ 12.10 0.7 $ 3,357 Exercisable options at March 31, 2016 367,982 $ 12.10 0.7 $ 3,357 Unvested options at March 31, 2016 — $ — — $ — The total intrinsic value of options exercised during the three months ended March 31, 2016 and 2015 was $2.9 million and $643 thousand, respectively. Restricted Stock The weighted-average grant-date fair value per share in the table below is calculated by taking the total aggregate cost of the restricted shares issued divided by the number of shares of restricted stock issued. The aggregate cost of the restricted stock was calculated by multiplying the number of shares granted at each of the grant dates by the closing stock price of the Company’s common stock on the date of the grant. The following table summarizes the restricted stock activity under the Equity Plan for the period indicated: Number of Shares Weighted-Average Grant-Date Fair Value Restricted Stock: Unvested at December 31, 2015 311,458 $ 19.29 Granted 41,809 22.65 Vested (36,325 ) 18.95 Cancelled and forfeited (4,000 ) — Unvested at March 31, 2016 312,942 $ 20.02 Restricted stock compensation expense related to the restricted stock grants reflected in the table above was $776 thousand and $512 thousand for the three months ended March 31, 2016 and 2015, respectively. Restricted stock awards reflected in the table above are valued at the closing stock price on the date of grant and are expensed to stock based compensation expense over the period for which the related service is performed. In 2015, the Company granted 40,000 shares of Restricted Stock Unit (“RSU”) under the Equity Plan to one of its executive officers. Such grant is reflected in the table above. The shares of common stock underlying the 40,000 shares of RSU will not be issued until the RSUs vest and are not included in the Company’s shares issued and outstanding as of March 31, 2016. The RSUs are valued at the closing stock price on the date of grant and are expensed to stock based compensation expense over the period for which the related service is performed.

Equity [Abstract]
Shareholders' Equity	Note 12 – Shareholders’ Equity Common Stock Holders of shares of the Company’s common stock are entitled to one vote for each share held of record on all matters voted upon by shareholders. Furthermore, the holders of the Company’s common stock have no preemptive rights to subscribe for new issue securities, and shares of the Company’s common stock are not subject to redemption, conversion, or sinking fund provisions. With respect to the payment of dividends, after the preferential dividends upon all other classes and series of stock entitled thereto have been paid or declared and set apart for payment, then the holders of the Company’s common stock are entitled to such dividends as may be declared by the Company’s board of directors out of funds legally available under the laws of the State of California. Upon the Company’s liquidation or dissolution, the assets legally available for distribution to holders of the Company’s shares of common stock, after payment of all the Company’s obligations and payment of any liquidation preference of all other classes and series of stock entitled thereto, including the Company’s preferred stock, are distributable ratably among the holders of the Company’s common stock. During 2016, the Company issued 189,489 shares of stock from the exercise of employee stock options for a total value of $1.4 million. The Company also issued 41,809 shares of restricted stock to the Company’s directors and employees, cancelled 4,000 shares of unvested restricted stock related to employee turnover and cancelled 13,304 shares of restricted stock that had a value of $294 thousand when employees elected to pay their tax obligation via the repurchase of the stock by the Company. The net issuance of restricted stock for 2016 was 37,809 shares. The Equity Plan, as amended, allows employees to make an election to have a portion of their restricted stock that became vested during the year repurchased by the Company to provide funds to pay the employee’s tax obligation related to the vesting of the stock. Preferred Stock The Company completed the merger with 1 st st Dividends on the Company’s Series A Preferred Stock are payable quarterly in arrears if authorized and declared by the Company’s board of directors out of legally available funds, on a non-cumulative basis, on the $1 thousand per share liquidation preference amount. Dividends are payable on January 1, April 1, July 1 and October 1 of each year. The current coupon dividend rate was adjusted to 9% on March 1, 2016 through perpetuity. However, the dividend yield through November 30, 2018 approximates 7% as a result of business combination accounting. Dividends on the Series A Preferred Stock are non-cumulative. There is no sinking fund with respect to dividends on the Series A Preferred Stock. So long as the Company’s Series A Preferred Stock remains outstanding, the Company may declare and pay dividends on the common stock only if full dividends on all outstanding shares of Series A Preferred Stock for the most recently completed dividend period have been or are contemporaneously declared and paid. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, holders of the Series A Preferred Stock will be entitled to receive for each share of Series A Preferred Stock, out of the Company’s assets or proceeds available for distribution to the Company’s shareholders, subject to any rights of the Company’s creditors, before any distribution of assets or proceeds is made to or set aside for the holders of the common stock, payment of an amount equal to the sum of (i) the $1 thousand liquidation preference amount per share and (ii) the amount of any accrued and unpaid dividends on the Series A Preferred Stock. To the extent the assets or proceeds available for distribution to shareholders are not sufficient to fully pay the liquidation payments owing to the holders of the Series A Preferred Stock and the holders of any other class or series of the stock ranking equally with the Series A Preferred Stock, the holders of the Series A Preferred Stock and such the Company’s stock will share ratably in the distribution. Holders of the Series A Preferred Stock have no right to exchange or convert their shares into common stock or any other securities and do not have voting rights.

Fair Value Disclosures [Abstract]
Fair Value Information	Note 14 - Fair Value Information Fair Value Measurement Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for an asset or liability in an orderly transaction between market participants at the measurement date. ASC Topic 825 requires disclosure of the fair value of financial assets and financial liabilities, including both those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis and a non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value, and for estimating the fair value of financial assets and financial liabilities not recorded at fair value, are discussed below. In accordance with accounting guidance, the Company groups its financial assets and financial liabilities measured 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 as follows: • Level 1 – Observable unadjusted quoted market prices in active markets for identical assets and liabilities that the reporting entity has the ability to access at the measurement date. • Level 2 – Significant other observable market based inputs, other than Level 1 prices such as quoted prices for similar assets or liabilities or unobservable inputs that are corroborated by market data. This includes quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data, either directly or indirectly. This would include those financial instruments that are valued using models or other valuation methodologies where substantially all of the assumptions are observable in the marketplace, can be derived from observable market data or are supported by observable levels at which transactions are executed in the marketplace. • Level 3 – Significant unobservable inputs that reflect a reporting entity’s evaluation about the assumptions that market participants would use in pricing an asset or liability. Assets measured utilizing level 3 are for positions that are not traded in active markets or are subject to transfer restrictions, and or where valuations are adjusted to reflect illiquidity and or non-transferability. These assumptions are not corroborated by market data. This is comprised of financial instruments whose fair value is estimated based on internally developed models or methodologies utilizing significant inputs that are generally less readily observable from objective sources. Management uses a combination of reviews of the underlying financial statements, appraisals and management’s judgment regarding credit quality to determine the value of the financial asset or liability. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Management maximizes the use of observable inputs and attempts to minimize the use of unobservable inputs when determining fair value measurements. The following is a description of both the general and specific valuation methodologies used for certain instruments measured at fair value, as well as the general classification of these instruments pursuant to the valuation hierarchy. Investment Securities Available-for-Sale and Held-to-Maturity Securities classified as available-for-sale are accounted for at their current fair value rather than amortized historical cost. Unrealized gains or losses are excluded from net income and reported as an amount net of taxes as a separate component of accumulated other comprehensive income included in shareholders’ equity. Securities classified as held-to-maturity are accounted for at their amortized historical cost. The Company considers the inputs utilized to fair value the available-for-sale and held-to-maturity investment securities to be observable market inputs and classified these financial assets within the Level 2 fair value hierarchy. Management bases the fair value for these investments primarily on third party price indications provided by independent pricing sources utilized by the Company’s bond accounting system to obtain market pricing on its individual securities. Vining Sparks, who provides the Company with its bond accounting system, utilizes pricing from three independent third party pricing sources for pricing of securities. These third party pricing sources utilize quoted market prices, or when quoted market prices are not available, the fair values are estimated using nationally recognized third-party vendor pricing models, of which the inputs are observable. However, the fair value reported may not be indicative of the amounts that could be realized in an actual market exchange. The fair value of the Company’s U.S. Agency and available-for-sale and held-to-maturity investment securities are calculated using an option adjusted spread model from one of the nationally recognized third-party pricing models. Depending on the assumptions used and the treasury yield curve and other interest rate assumptions, the fair value could vary significantly in the near term.

Additionally, there were no transfers of assets either between Level 1 and Level 2 nor in or out of Level 3 of the fair value hierarchy for assets measured on a recurring basis for the period ended March 31, 2016. Assets Measured at Fair Value on a Non-recurring Basis The Company may be required periodically, to measure certain financial assets and financial liabilities at fair value on a nonrecurring basis, that is, the instruments are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). These include assets that are measured at the lower of cost or fair value that were recognized at fair value below cost at the end of or during the period. There were no transfers of assets either between Level 1 and Level 2 nor in or out of Level 3 of the fair value hierarchy for assets measured on a non-recurring basis for the three months ended March 31, 2016. The following table presents the balances of assets and liabilities measured at fair value on a non-recurring basis by caption and by level within the fair value hierarchy as of the dates indicated (dollars in thousands): Net Carrying Value Quoted Prices Significant Significant Financial Assets – March 31, 2016 Collateral dependent impaired loans with specific valuation allowance and/or partial charge-offs (non-purchased credit impaired loans) $ — $ — $ — $ — Other real estate owned — — — — Total $ — $ — $ — $ — Financial Assets – December 31, 2015 Collateral dependent impaired loans with specific valuation allowance and/or partial charge-offs (non-purchased credit impaired loans) $ — $ — $ — $ — Other real estate owned 325 — — 325 Total $ 325 $ — $ — $ 325 The following table presents the significant unobservable inputs used in the fair value measurements for Level 3 assets and liabilities measured at fair value on a recurring or non-recurring basis as of the dates indicated (dollars in thousands): Fair Value Valuation Methodology Valuation Model Unobservable Financial Assets – March 31, 2016 Collateral dependent impaired loans with specific valuation allowance and/or partial charge-off $ — — — — Other real estate owned $ — — — — Total $ — Financial Assets – December 31, 2015 Collateral dependent impaired loans with specific valuation allowance and/or partial charge-off $ — — — — Other real estate owned $ 325 Broker opinion of value Sales approach Estimated selling costs 6% Total $ 325 Fair Value of Financial Assets and Liabilities ASC Topic 825 requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or on a non-recurring basis. The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to develop the estimates of fair value. Accordingly, the estimates presented below are not necessarily indicative of the amounts the Company could have realized in a current market exchange as of March 31, 2016 and December 31, 2015. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. The description of the valuation methodologies used for assets and liabilities measured at fair value and for estimating fair value for financial instruments not recorded at fair value has been described above.

Accounting Policies [Abstract]
Use of Estimates in the Preparation of Consolidated Financial Statements	Use of Estimates in the Preparation of Consolidated Financial Statements The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In addition, these accounting principles require the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements. Estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan loss and various assets and liabilities measured at fair value. While management uses the most current available information to recognize losses on loans, future additions to the allowance for loan loss may be necessary based on, among other factors, changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan loss. Regulatory agencies may require the Company to recognize changes to the allowance for loan loss based on their judgment about information available to them at the time of their examination.
