Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The interim unaudited condensed consolidated financial statements of Central Valley Community Bancorp and subsidiary have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the SEC). These interim condensed consolidated financial statements include the accounts of Central Valley Community Bancorp and its wholly owned subsidiary Central Valley Community Bank (the Bank) (collectively, the Company). All significant intercompany accounts and transactions have been eliminated in consolidation. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) have been omitted. The Company believes that the disclosures are adequate to make the information presented not misleading. These interim unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s 2016 Annual Report to Shareholders on Form 10-K. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the Company’s financial position at September 30, 2017 , and the results of its operations for the three and nine months ended September 30, 2017 and 2016 and its cash flows for the nine month interim periods ended September 30, 2017 and 2016 have been included. The results of operations for interim periods are not necessarily indicative of results for the full year. The preparation of these interim unaudited condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Management has determined that since all of the banking products and services offered by the Company are available in each branch of the Bank, all branches are located within the same economic environment, and management does not allocate resources based on the performance of different lending or transaction activities, it is appropriate to aggregate the Bank branches and report them as a single operating segment. No customer accounts for more than 10 percent of revenues for the Company or the Bank. Impact of New Financial Accounting Standards: FASB Accounting Standards Update (ASU) 2016-09 - Revenue from Contracts with Customers (Topic 606): Revenue from Contracts with Customers was issued in May 2014 . This ASU is the result of a joint project initiated by the FASB and the International Accounting Standards Board (IASB) to clarify the principles for recognizing revenue, and to develop common revenue standards and disclosure requirements that would: (1) remove inconsistencies and weaknesses in revenue requirements; (2) provide a more robust framework for addressing revenue issues; (3) improve comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets; (4) provide more useful information to users of financial statements through improved disclosures; and (5) simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. The guidance affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets. The core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides steps to follow to achieve the core principle. An entity should disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Qualitative and quantitative information is required with regard to contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. This ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods therein, with early adoption permitted for reporting periods beginning after December 15, 2016. The Company plans to adopt ASU 2014-09 on January 1, 2018 utilizing the modified retrospective approach. Since the guidance does not apply to revenue associated with financial instruments such as loans and investments, which are accounted for under other provisions of GAAP, we do not expect it to impact interest income, our largest component of income. The Company is currently performing an overall assessment of revenue streams potentially affected by the ASU, including certain deposit related fees and interchange fees, to determine the potential impact of this guidance on our consolidated financial statements. FASB Accounting Standards Update (ASU) 2016-01 - Financial Instruments - Overall (Subtopic 825-10) : Recognition and Measurement of Financial Assets and Financial Liabilities, was issued January 2016. The main provisions of the update are to eliminate the available-for-sale classification of accounting for equity securities and to adjust the fair value disclosures for financial instruments carried at amortized costs such that the disclosed fair values represent an exit price as opposed to an entry price. The provisions of this update will require that equity securities be carried at fair market value on the balance sheet and any periodic changes in value will be adjustments to the income statement. A practical expedient is provided for equity securities without a readily determinable fair value, such that these securities can be carried at cost less any impairment. ASU No. 2016-01 is effective for interim and annual reporting periods beginning after December 15, 2017. The Company has performed a preliminary evaluation of the provisions of ASU No. 2016-01 and based on this evaluation, has determined that ASU No. 2016-01 is not expected to have a material impact on the Company’s financial position, results of operations or its cash flows. FASB Accounting Standards Update (ASU) 2016-02 - Leases - Overall (Subtopic 845), was issued February 2016. The update requires all leases, with the exception of short-term leases that have contractual terms of no greater than one year, to be recorded on the balance sheet. Under the provisions of the update, leases classified as operating will be reflected on the balance sheet with the recognition of both a right-of-use asset and a lease liability. Under the update, a distinction will exist between finance and operating type leases and the rules for determining which classification a lease will fall into are similar to existing rules. For public business entities, the amendments of this update are effective for interim and annual periods beginning after December 15, 2018. The update requires a modified retrospective transition under which comparative balance sheets from the earliest historical period presented will be revised to reflect what the financials would have looked like were the provisions of the update applied consistently in all prior periods. The Company is currently evaluating the provisions of ASU No. 2016-02 and has determined that the provisions of ASU No. 2016-02 will result in an increase in assets to recognize the present value of the lease obligations with a corresponding increase in liabilities; however, the Company does not expect this to have a material impact on the Company’s results of operations or cash flows. FASB Accounting Standards Update (ASU) 2016-09 - Compensation - Stock Compensation (Subtopic 718) : Improvements to Employee Share-Based Payment Accounting, was issued March 2016. T his ASU includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. Some of the key provisions of this new ASU include: (1) companies will no longer record excess tax benefits and certain tax deficiencies in additional paid-in capital (“APIC”). Instead, they will record all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement, and APIC pools will be eliminated. The guidance also eliminates the requirement that excess tax benefits be realized before companies can recognize them. In addition, the guidance requires companies to present excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity; (2) increase the amount an employer can withhold to cover income taxes on awards and still qualify for the exception to liability classification for shares used to satisfy the employer’s statutory income tax withholding obligation. The new guidance will also require an employer to classify the cash paid to a tax authority when shares are withheld to satisfy its statutory income tax withholding obligation as a financing activity on its statement of cash flows (current guidance did not specify how these cash flows should be classified); and (3) permit companies to make an accounting policy election for the impact of forfeitures on the recognition of expense for share-based payment awards. Forfeitures can be estimated, as required today, or recognized when they occur. ASU No. 2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016. Early adoption was permitted, but all of the guidance must be adopted in the same period. Effective January 1, 2017, the Company adopted ASU 2016-09 “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” including the election to continue to treat option forfeitures on an expected basis and to provide cash flow disclosures on a prospective basis. During the three and nine months ended September 30, 2017 the adoption of this standard resulted in the recognition of $0 and $104,000 , respectively in excess tax benefits related to the exercise of stock options during the period. FASB Accounting Standards Update (ASU) 2016-13 - Measurement of Credit Losses on Financial Instruments (Subtopic 326) : Financial Instruments - Credit Losses, commonly referred to as “CECL,” was issued June 2016. The provisions of the update eliminate the probable initial recognition threshold under current GAAP which requires reserves to be based on an incurred loss methodology. Under CECL, reserves required for financial assets measured at amortized cost will reflect an organization’s estimate of all expected credit losses over the contractual term of the financial asset and thereby require the use of reasonable and supportable forecasts to estimate future credit losses. Because CECL encompasses all financial assets carried at amortized cost, the requirement that reserves be established based on an organization’s reasonable and supportable estimate of expected credit losses extends to held to maturity (“HTM”) debt securities. Under the provisions of the update, credit losses recognized on available for sale (“AFS”) debt securities will be presented as an allowance as opposed to a write-down. In addition, CECL will modify the accounting for purchased loans, with credit deterioration since origination, so that reserves are established at the date of acquisition for purchased loans. Under current GAAP a purchased loan’s contractual balance is adjusted to fair value through a credit discount and no reserve is recorded on the purchased loan upon acquisition. Since under CECL reserves will be established for purchased loans at the time of acquisition, the accounting for purchased loans is made more comparable to the accounting for originated loans. Finally, increased disclosure requirements under CECL require organizations to present the currently required credit quality disclosures disaggregated by the year of origination or vintage. The FASB expects that the evaluation of underwriting standards and credit quality trends by financial statement users will be enhanced with the additional vintage disclosures. For public business entities that are SEC filers, the amendments of the update will become effective beginning January 1, 2020. While the Company is currently evaluating the provisions of ASU No. 2016-13 to determine the potential impact the new standard will have on the Company’s Consolidated Financial Statements, it has taken steps to prepare for the implementation when it becomes effective, such as forming an internal task force, gathering pertinent data, consulting with outside professionals, and evaluating its current IT systems. Management expects to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the first reporting period in which the new standard is effective, but cannot yet estimate the magnitude of the one-time adjustment or the overall impact of the new guidance on the Company’s financial position, results of operations or cash flows. FASB Accounting Standards Update (ASU) 2017-04 - Intangibles Goodwill and Other (Subtopic 350) : Simplifying the Test for Goodwill Impairment, was issued January 2017. The provisions of the update eliminate the existing second step of the goodwill impairment test which provides for the allocation of reporting unit fair value among existing assets and liabilities, with the net leftover amount representing the implied fair value of goodwill. In replacement of the existing goodwill impairment rule, the update will provide that impairment should be recognized as the excess of any of the reporting unit’s goodwill over the fair value of the reporting unit. Under the provisions of this update, the amount of the impairment is limited to the carrying value of the reporting unit’s goodwill. For public business entities that are SEC filers, the amendments of the update will become effective in fiscal years beginning after December 15, 2019. FASB Accounting Standards Update (ASU) 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) : Premium Amortization on Purchased Callable Debt Securities, was issued March 2017. The provisions of the update require premiums recognized upon the purchase of callable debt securities to be amortized to the earliest call date in order to avoid losses recognized upon call. For public business entities that are SEC filers, the amendments of the update will become effective in fiscal years beginning after December 15, 2018. Management does not expect the requirements of this update to have a material impact on the Company’s financial position, results of operations or cash flows. FASB Accounting Standards Update (ASU) 2017-09 - Compensation - Stock Compensation (Subtopic 718) : Scope of Modification Accounting, was issued May 2017. The amendments in ASU 2017-09 provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. An entity should account for the effects of a modification unless all of the following conditions are met: the fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified; the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; and the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments in this Update should be applied prospectively to an award modified on or after the adoption date. The amendments in this Update are effective for annual periods, and interim periods within those annual periods, beginning after December 31, 2017. Early adoption is permitted, including adoption in any interim period. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements. FASB Accounting Standards Update (ASU) 2017-12 - Derivatives and Hedging (Topic 815) ; T argeted Improvements to Accounting for Hedging Activities was issued August 2017. This ASU’s objectives are to (1) improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities by better aligning the entity’s financial reporting for hedging relationships with those risk management activities; and (2) reduce the complexity of and simplify the application of hedge accounting by preparers. ASU No. 2017-12 is effective for interim and annual reporting periods beginning after December 15, 2018; early adoption is permitted. The Company currently does not designate any derivative financial instruments as formal hedging relationships, and therefore, does not utilize hedge accounting. However, the Company is currently evaluating this ASU to determine whether its provisions will enhance the Company’s ability to employ risk management strategies, while improving the transparency and understanding of those strategies for financial statement users.

Sierra Vista Bank’s assets as of October 1, 2016 totaled approximately $155.154 million. The acquired assets and liabilities were recorded at fair value at the date of acquisition. Under the terms of the merger agreement, the Company issued an aggregate of approximately 1.059 million shares of its common stock and cash totaling approximately $9.469 million to the former shareholders of Sierra Vista Bank. In accordance with GAAP guidance for business combinations, the Company recorded $10.314 million of goodwill and $508,000 of other intangible assets on the acquisition date. The other intangible assets are primarily related to core deposits and are being amortized using a straight-line method over a period of ten years with no significant residual value. For tax purposes, purchase accounting adjustments including goodwill are all non-taxable and/or non-deductible. The fair values of assets acquired and liabilities assumed are subject to adjustment during the first twelve months after the acquisition date if additional information becomes available to indicate a more accurate or appropriate value for an asset or liability. During the nine-month period ended September 30, 2017 , the Company determined that a measurement adjustment was appropriate which resulted in an $80,000 increase to goodwill. The acquisition was consistent with the Company’s strategy to build a regional presence in Central California. The acquisition offers the Company the opportunity to increase profitability by introducing existing products and services to the acquired customer base as well as add new customers in the expanded region. Goodwill arising from the acquisition consisted largely of synergies and the cost savings resulting from the combined operations. Pro Forma Results of Operations The following table presents pro forma results of operations information for the periods presented as if the acquisition had occurred on January 1, 2016 after giving effect to certain adjustments. The unaudited pro forma results of operations for the nine months ended September 30, 2016 include the historical accounts of the Company and Sierra Vista Bank and pro forma adjustments as may be required, including the amortization of intangibles with definite lives and the amortization or accretion of any premiums or discounts arising from fair value adjustments for assets acquired and liabilities assumed. The pro forma information is intended for informational purposes only and is not necessarily indicative of the Company’s future operating results or operating results that would have occurred had the acquisition been completed at the beginning of 2016. No assumptions have been applied to the pro forma results of operations regarding possible revenue enhancements, expense efficiencies or asset dispositions. (In thousands, except per-share amounts): Pro Forma Results of Operations For the Nine Months (In thousands, except per share amounts) 2016 Net interest income $ 37,741 (Reversal of) Provision for credit losses (5,750 ) Non-interest income 7,692 Non-interest expense 36,449 Income before provision for income taxes 14,734 Provision for income taxes 4,326 Net income $ 10,408 Basic earnings per common share $ 0.95 Diluted earnings per common share $ 0.94 On October 1, 2017, the Company completed the acquisition of Folsom Lake Bank (“Folsom”) for an aggregate transaction value of $28.5 million . Folsom was merged into the Bank, and the Company issued 1,276,888 shares of common stock to the former shareholders of Folsom. The Company also assumed the outstanding Folsom stock options. Folsom operated three full-service branches in Folsom, Rancho Cordova, and Roseville, California. Folsom’s assets (unaudited) as of September 30, 2017 totaled approximately $197.3 million . The acquired assets and liabilities will be recorded at fair value at the date of acquisition and will be reflected in the Company’s December 31, 2017 financial statements. The Company also expects to record goodwill and a core deposit intangible related to this transaction, but those amounts are not yet known as the initial fair value accounting is incomplete. The goodwill will not be deductible for tax purposes.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair Value Hierarchy Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. In accordance with applicable guidance, the Company groups its assets and 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. Valuations within these levels are based upon: Level 1 — Quoted market prices (unadjusted) for identical instruments traded in active exchange markets that the Company has the ability to access as of the measurement date. Level 2 — 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 or can be corroborated by observable market data. Level 3 — Model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use on pricing the asset or liability. Valuation techniques include management judgment and estimation which may be significant. Management monitors the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, we report the transfer at the beginning of the reporting period. The estimated carrying and fair values of the Company’s financial instruments are as follows (in thousands): September 30, 2017 Carrying Amount Fair Value (In thousands) Level 1 Level 2 Level 3 Total Financial assets: Cash and due from banks $ 26,195 $ 26,195 $ — $ — $ 26,195 Interest-earning deposits in other banks 9,494 9,494 — — 9,494 Federal funds sold — — — — — Available-for-sale investment securities 515,077 7,486 507,591 — 515,077 Loans, net 769,810 — — 781,683 781,683 Federal Home Loan Bank stock 5,594 N/A N/A N/A N/A Accrued interest receivable 6,345 19 3,138 3,188 6,345 Financial liabilities: Deposits 1,218,385 1,097,742 119,843 — 1,217,585 Junior subordinated deferrable interest debentures 5,155 — — 3,400 3,400 Accrued interest payable 103 — 64 39 103 December 31, 2016 Carrying Amount Fair Value (In thousands) Level 1 Level 2 Level 3 Total Financial assets: Cash and due from banks $ 28,185 $ 28,185 $ — $ — $ 28,185 Interest-earning deposits in other banks 10,368 10,368 — — 10,368 Federal funds sold 15 15 — — 15 Available-for-sale investment securities 547,749 7,416 540,333 — 547,749 Loans, net 747,302 — — 761,023 761,023 Federal Home Loan Bank stock 5,594 N/A N/A N/A N/A Accrued interest receivable 7,885 26 4,517 3,342 7,885 Financial liabilities: Deposits 1,255,979 1,099,200 156,711 — 1,255,911 Short-term borrowings 400 — 400 — 400 Junior subordinated deferrable interest debentures 5,155 — — 3,235 3,235 Accrued interest payable 144 — 111 33 144 These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates. These estimates are made at a specific point in time based on relevant market data and information about the financial instruments. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the fair values presented. The methods and assumptions used to estimate fair values are described as follows: (a) Cash and Cash Equivalents — The carrying amounts of cash and due from banks, interest-earning deposits in other banks, and Federal funds sold approximate fair values and are classified as Level 1. (b) Investment Securities — Investment securities in Level 1 are mutual funds and fair values are based on quoted market prices for identical instruments traded in active markets. Fair values for investment securities classified in Level 2 are based on quoted market prices for similar securities in active markets. For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators. (c) Loans — Fair values of loans are estimated as follows: For variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values resulting in a Level 3 classification. Purchased credit impaired (PCI) loans are measured at estimated fair value on the date of acquisition. Carrying value is calculated as the present value of expected cash flows and approximates fair value. Fair values for other loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality resulting in a Level 3 classification. Impaired loans are initially valued at the lower of cost or fair value. Impaired loans carried at fair value generally receive specific allocations of the allowance for credit losses. For collateral dependent real estate loans, fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price. (d) FHLB Stock — It is not practicable to determine the fair value of FHLB stock due to restrictions placed on its transferability. (e) Other real estate owned — OREO is measured at fair value less estimated costs to sell when acquired, establishing a new cost basis. Fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process to adjust for differences between the comparable sales and income data available. The Company records OREO as non-recurring with level 3 measurement inputs. (f) Deposits — Fair value of demand deposit, savings, and money market accounts are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amount), resulting in a Level 1 classification. Fair value for fixed and variable rate certificates of deposit are estimated using discounted cash flow analyses using interest rates offered at each reporting date by the Company for certificates with similar remaining maturities resulting in a Level 2 classification. (g) Short-Term Borrowings — The fair values of the Company’s federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings, generally maturing within ninety days, are based on the market rates for similar types of borrowing arrangements resulting in a Level 2 classification. (h) Other Borrowings — The fair values of the Company’s long-term borrowings are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 2 classification. The fair values of the Company’s Subordinated Debentures are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 3 classification. (i) Accrued Interest Receivable/Payable — The fair value of accrued interest receivable and payable is based on the fair value hierarchy of the related asset or liability. (j) Off-Balance Sheet Instruments — Fair values for off-balance sheet, credit-related financial instruments 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. The fair value of commitments is not considered significant for financial reporting purposes. Assets Recorded at Fair Value The following tables present information about the Company’s assets and liabilities measured at fair value on a recurring and non-recurring basis as of September 30, 2017 : Recurring Basis The Company is required or permitted to record the following assets at fair value on a recurring basis as of September 30, 2017 (in thousands).

Fair values for available-for-sale investment securities in Level 2 are based on quoted market prices for similar securities in active markets. For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators. Management evaluates the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total assets, total liabilities or total earnings. During the nine months ended September 30, 2017 , no transfers between levels occurred. There were no Level 3 assets measured at fair value on a recurring basis at or during the nine months ended September 30, 2017 . Also there were no liabilities measured at fair value on a recurring basis at September 30, 2017 . Non-recurring Basis The Company may be required, from time to time, to measure certain assets and liabilities at fair value on a non-recurring basis. These include assets and liabilities that are measured at the lower of cost or fair value that were recognized at fair value which was below cost at September 30, 2017 (in thousands). Description Fair Value Level 1 Level 2 Level 3 Consumer: Equity loans and lines of credit $ 16 $ — $ — $ 16 Total impaired loans 16 — — 16 Other repossessed assets $ 194 $ — $ — $ 194 Other real estate owned — — — — Total assets measured at fair value on a non-recurring basis $ 210 $ — $ — $ 210 At the time a loan is considered impaired, it is valued at the lower of cost or fair value. Impaired loans carried at fair value generally receive specific allocations of the allowance for credit losses. For collateral dependent real estate loans, fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. The fair value of impaired loans is based on the fair value of the collateral. Impaired loans were determined to be collateral dependent and categorized as Level 3 due to ongoing real estate market conditions resulting in inactive market data, which in turn required the use of unobservable inputs and assumptions in fair value measurements. Impaired loans evaluated under the discounted cash flow method are excluded from the table above. The discounted cash flow methods as prescribed by ASC Topic 310 is not a fair value measurement since the discount rate utilized is the loan’s effective interest rate which is not a market rate. There were no changes in valuation techniques used during the nine month period ended September 30, 2017 . Appraisals for collateral-dependent impaired loans are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value is compared with independent data sources such as recent market data or industry-wide statistics. Impaired loans that are measured for impairment using the fair value of the collateral for collateral dependent loans, had a principal balance of $45,000 with a valuation allowance of $29,000 at September 30, 2017 , resulting in fair value of $16,000 . The valuation allowance represent specific allocation for the allowance for credit losses for impaired loans. There were no charge-offs related to loans carried at fair value during the nine months ended September 30, 2017 and 2016 . Activity related to changes in the allowance for loan losses related to impaired loans for the three months ended September 30, 2017 and 2016 was not considered significant for disclosure purposes. At September 30, 2017 , other repossessed assets were recorded at their estimated fair value of $194,000 . Write downs related to other repossessed assets for the three and nine months ended September 30, 2017 and 2016 were not significant for disclosure purposes. There were no liabilities measured at fair value on a non-recurring basis at September 30, 2017 .

Investments, Debt and Equity Securities [Abstract]
Investments	Investments The investment portfolio consists primarily of U.S. Government sponsored entity and agency securities collateralized by residential mortgage obligations, private label residential mortgage backed securities (PLRMBS), and obligations of states and political subdivisions securities. As of September 30, 2017 , $96,042,000 of these securities were held as collateral for borrowing arrangements, public funds, and for other purposes. The fair value of the available-for-sale investment portfolio reflected a net unrealized gain of $7,600,000 at September 30, 2017 compared to an unrealized loss of $891,000 at December 31, 2016 . The unrealized gain recorded is net of $3,195,000 and $(375,000) in tax liabilities (benefits) as accumulated other comprehensive income within shareholders’ equity at September 30, 2017 and December 31, 2016 , respectively. The following table sets forth the carrying values and estimated fair values of our investment securities portfolio at the dates indicated (in thousands): September 30, 2017 Available-for-Sale Securities Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value Debt securities: U.S. Government agencies $ 61,253 $ 598 $ (47 ) $ 61,804 Obligations of states and political subdivisions 204,841 8,660 (516 ) 212,985 U.S. Government sponsored entities and agencies collateralized by residential mortgage obligations 190,028 696 (2,375 ) 188,349 Private label mortgage backed securities 43,855 977 (379 ) 44,453 Other equity securities 7,500 — (14 ) 7,486 Total available-for-sale $ 507,477 $ 10,931 $ (3,331 ) $ 515,077 December 31, 2016 Available-for-Sale Securities Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value Debt securities: U.S. Government agencies $ 69,005 $ 242 $ (277 ) $ 68,970 Obligations of states and political subdivisions 288,543 6,109 (4,353 ) 290,299 U.S. Government sponsored entities and agencies collateralized by residential mortgage obligations 181,785 484 (4,048 ) 178,221 Private label mortgage backed securities 1,807 1,036 — 2,843 Other equity securities 7,500 — (84 ) 7,416 Total available-for-sale $ 548,640 $ 7,871 $ (8,762 ) $ 547,749 Proceeds and gross realized gains (losses) from the sales or calls of investment securities for the periods ended September 30, 2017 and 2016 are shown below (in thousands): For the Three Months Ended September 30, For the Nine Months Available-for-Sale Securities 2017 2016 2017 2016 Proceeds from sales or calls $ 26,286 $ 21,239 $ 101,293 $ 84,283 Gross realized gains from sales or calls 210 306 3,601 1,277 Gross realized losses from sales or calls (41 ) (20 ) (793 ) (137 ) For the Three Months Ended September 30, For the Nine Months Held-to-Maturity Securities 2017 2016 2017 2016 Proceeds from sales or calls $ — $ — $ — $ 9,257 Gross realized gains from sales or calls — — — 696 During 2014, to better manage our interest rate risk, the Company transferred from available-for-sale to held-to-maturity selected municipal securities in our portfolio having a book value of approximately $31 million , a market value of approximately $32 million , and a net unrecognized gain of approximately $163,000 . During the first quarter of 2016, the Company sold certain investment securities of which the Company identified that five of the 13 securities sold were previously designated as held-to-maturity (HTM). Through an oversight during the portfolio restructuring analysis related to this transaction, the Company unintentionally sold these five HTM securities. The book value of the HTM securities sold was $8.5 million . The gain realized on the sale of the HTM securities was $696,000 . As such, the Company was required to reclassify the remaining HTM securities with a fair value of $23.1 million to the available-for-sale designation. Losses recognized in 2017 and 2016 were incurred in order to reposition the investment securities portfolio based on the current rate environment. The securities which were sold at a loss were acquired when the rate environment was not as volatile. As market interest rates or risks associated with a security’s issuer continue to change and impact the actual or perceived values of investment securities, the Company may determine that selling these securities and using proceeds to purchase securities that fit with the Company’s current risk profile is appropriate and beneficial to the Company. The provision for income taxes includes $1,181,000 and $479,000 income tax impact from the reclassification of unrealized net gains on securities to realized net gains on securities for the nine months ended September 30, 2017 and 2016 , respectively. The provision for income taxes includes $71,000 and $120,000 income tax impact from the reclassification of unrealized net gains on available-for-sale securities to realized net gains on available-for-sale securities for the three months ended September 30, 2017 and 2016 , respectively. Investment securities, aggregated by investment category, with unrealized losses as of the dates indicated are summarized and classified according to the duration of the loss period as follows (in thousands): September 30, 2017 Less than 12 Months 12 Months or More Total Fair Unrealized Fair Unrealized Fair Unrealized Available-for-Sale Securities Value Losses Value Losses Value Losses Debt securities: U.S. Government agencies $ — $ — $ 7,272 $ (47 ) $ 7,272 $ (47 ) Obligations of states and political subdivisions 8,239 (65 ) 18,216 (451 ) 26,455 (516 ) U.S. Government sponsored entities and agencies collateralized by residential mortgage obligations 54,089 (199 ) 66,868 (2,176 ) 120,957 (2,375 ) Private label mortgage backed securities 41,941 (379 ) — — 41,941 (379 ) Other equity securities 7,486 (14 ) — — 7,486 (14 ) Total available-for-sale $ 111,755 $ (657 ) $ 92,356 $ (2,674 ) $ 204,111 $ (3,331 ) December 31, 2016 Less than 12 Months 12 Months or More Total Fair Unrealized Fair Unrealized Fair Unrealized Available-for-Sale Securities Value Losses Value Losses Value Losses Debt securities: U.S. Government agencies $ 34,586 $ (198 ) $ 10,438 $ (79 ) $ 45,024 $ (277 ) Obligations of states and political subdivisions 122,522 (4,353 ) — — 122,522 (4,353 ) U.S. Government sponsored entities and agencies collateralized by residential mortgage obligations 118,719 (3,866 ) 7,666 (182 ) 126,385 (4,048 ) Other equity securities 7,416 (84 ) — — 7,416 (84 ) Total available-for-sale $ 283,243 $ (8,501 ) $ 18,104 $ (261 ) $ 301,347 $ (8,762 ) The Company periodically evaluates each investment security for other-than-temporary impairment, relying primarily on industry analyst reports, observation of market conditions and interest rate fluctuations. The portion of the impairment that is attributable to a shortage in the present value of expected future cash flows relative to the amortized cost should be recorded as a current period charge to earnings. The discount rate in this analysis is the original yield expected at time of purchase. As of September 30, 2017, the Company performed an analysis of the investment portfolio to determine whether any of the investments held in the portfolio had an other-than-temporary impairment (OTTI). The Company evaluated all individual available-for-sale investment securities with an unrealized loss at September 30, 2017 and identified those that had an unrealized loss for at least a consecutive 12 month period, which had an unrealized loss at September 30, 2017 greater than 10% of the recorded book value on that date, or which had an unrealized loss of more than $10,000. The Company also analyzed any securities that may have been downgraded by credit rating agencies. For those bonds that met the evaluation criteria, management obtained and reviewed the most recently published national credit ratings for those bonds. For those bonds that were obligations of states and political subdivisions with an investment grade rating by the rating agencies, the Company also evaluated the financial condition of the municipality and any applicable municipal bond insurance provider and concluded during March 2016 that a $136,000 credit related impairment related to one security with a fair value of $2,995,000 and a pre-impairment amortized cost of $3,131,000 existed. The Company recorded an other-than-temporary impairment loss of $136,000 during the nine months ended September 30, 2016 . There were no OTTI losses recorded during the nine months ended September 30, 2017 . There were no OTTI losses recorded during the three months ended September 30, 2016 . U.S. Government Agencies At September 30, 2017 , the Company held 21 U.S. Government agency securities, of which none were in a loss position for less than 12 months and two were in a loss position or had been in a loss position for 12 months or more. The unrealized losses on the Company’s investments in direct obligations of U.S. government agencies were caused by interest rate changes. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized costs of the investment. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company has the ability and intent to hold, and it is more likely than not that it will not be required to sell, those investments until a recovery of fair value, which may be the maturity date, the Company does not consider those investments to be other-than-temporarily impaired at September 30, 2017 . Obligations of States and Political Subdivisions At September 30, 2017 , the Company held 122 obligations of states and political subdivision securities of which two were in a loss position for less than 12 months and six were in a loss position or had been in a loss position for 12 months or more. The unrealized losses on the Company’s investments in obligations of states and political subdivision securities were caused by interest rate changes. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company has the ability to hold and does not intend to sell, and it is more likely than not that it will not be required to sell those investments until a recovery of fair value, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at September 30, 2017. U.S. Government Sponsored Entities and Agencies Collateralized by Residential Mortgage Obligations At September 30, 2017 , the Company held 142 U.S. Government sponsored entity and agency securities collateralized by residential mortgage obligations of which 23 were in a loss position for less than 12 months and 26 have been in a loss position for more than 12 months. The unrealized losses on the Company’s investments in U.S. Government sponsored entities and agencies collateralized by residential mortgage obligations were caused by interest rate changes. The contractual cash flows of those investments are guaranteed by an agency or sponsored entity of the U.S. Government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost of the Company’s investment. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company has the ability to hold and does not intend to sell, and it is more likely than not that it will not be required to sell those investments until a recovery of fair value, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at September 30, 2017 . Private Label Mortgage Backed Securities At September 30, 2017 , the Company had a total of 22 PLMBS with a remaining principal balance of $43,855,000 and a net unrealized gain of approximately $599,000 . Ten of these PLMBS with a remaining principal balance of $1,431,000 had credit ratings below investment grade. Eight of the PLMBS securities were in a loss position for less than 12 months at September 30, 2017 . Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company has the ability and intent to hold, and it is more likely than not that it will not be required to sell, those investments until a recovery of fair value, which may be the maturity date, the Company does not consider those investments to be other-than-temporarily impaired at September 30, 2017 . The Company continues to monitor these securities for indications that declines in value, if any, may be other-than-temporary. Other Equity Securities At September 30, 2017 , the Company had one mutual fund equity investment which had an unrealized loss of $14,000 at September 30, 2017 . The equity investment was in a loss position for less than 12 months at September 30, 2017 . The following tables provide a roll forward for the nine month periods ended September 30, 2017 and 2016 of investment securities credit losses recorded in earnings. The beginning balance represents the credit loss component for which OTTI occurred on debt securities in prior periods. Additions represent the first time a debt security was credit impaired or when subsequent credit impairments have occurred on securities for which OTTI credit losses have been previously recognized.

Purchased Credit Impaired Loans The Company has loans that were acquired in acquisitions for which there was at acquisition evidence of deterioration of credit quality since origination, and for which it was probable at acquisition that all contractually required payments would not be collected. The carrying amount of those loans is included in the balance sheet amounts of loans receivable at September 30, 2017 and December 31, 2016 . The amounts of loans at September 30, 2017 and December 31, 2016 are as follows (in thousands): September 30, 2017 December 31, 2016 Commercial $ 404 $ 612 Outstanding balance $ 404 $ 612 Carrying amount, net of allowance of $0 $ 404 $ 612 Purchased credit impaired (PCI) loans are recorded at the amount paid, such that there is no carryover of the seller’s allowance for loan losses. The Company estimates the amount and timing of expected cash flows for each loan and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan’s contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. Loans acquired during each year for which it was probable at acquisition that all contractually required payments would not be collected are as follows (in thousands): September 30, 2017 December 31, 2016 Contractually required payments receivable on PCI loans at acquisition: Commercial $ — $ 982 Total $ — $ 982 Cash flows expected to be collected at acquisition $ — $ 693 Fair value of acquired loans at acquisition $ — $ 631 Certain of the loans acquired by the Company that are within the scope of Topic ASC 310-30 are not accounted for using the income recognition model of the Topic because the Company cannot reliably estimate cash flows expected to be collected. The carrying amounts of such loans (which are included in the carrying amount, net of allowance, described above) are as follows. September 30, 2017 December 31, 2016 Loans acquired during the year $ — $ 631 Loans at the end of the period $ 404 $ 612 Allowance for Credit Losses The allowance for credit losses (the “Allowance”) is a valuation allowance for probable incurred credit losses in the Company’s loan portfolio. The Allowance is established through a provision for credit losses which is charged to expense. Additions to the Allowance are expected to maintain the adequacy of the total Allowance after credit losses and loan growth. Credit exposures determined to be uncollectible are charged against the Allowance. Cash received on previously charged-off credits is recorded as a recovery to the Allowance. The overall Allowance consists of two primary components, specific reserves related to impaired loans and general reserves for probable incurred losses related to loans that are not impaired. For all portfolio segments, the determination of the general reserve for loans that are not impaired is based on estimates made by management, including but not limited to, consideration of historical losses by portfolio segment (and in certain cases peer data) over the most recent 20 quarters, and qualitative factors including economic trends in the Company’s service areas, industry experience and trends, geographic concentrations, estimated collateral values, the Company’s underwriting policies, the character of the loan portfolio, and probable losses inherent in the portfolio taken as a whole.

Foregone interest on nonaccrual loans totaled $54,000 and $12,000 for the three month periods ended September 30, 2017 and 2016 , respectively. Troubled Debt Restructurings: As of September 30, 2017 and December 31, 2016 , the Company has a recorded investment in troubled debt restructurings of $2,722,000 and $3,109,000 , respectively. The Company has allocated $26,000 and $82,000 of specific reserves to loans whose terms have been modified in troubled debt restructurings as of September 30, 2017 and December 31, 2016 , respectively. The Company has committed to lend no additional amounts as of September 30, 2017 to customers with outstanding loans that are classified as troubled debt restructurings. During the nine month period ended September 30, 2017 two loans were modified as troubled debt restructurings. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan or an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk. During the same period, there were no troubled debt restructurings in which the amount of principal or accrued interest owed from the borrower was forgiven or which resulted in a charge-off or change to the allowance for loan losses.

Goodwill and Intangible Assets

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets Business combinations involving the Company’s acquisition of the equity interests or net assets of another enterprise give rise to goodwill. Total goodwill at September 30, 2017 was $40,311,000 consisting of $14,643,000 , $8,934,000 , $6,340,000 , and $10,394,000 representing the excess of the cost of Service 1 st Bancorp, Bank of Madera County, Visalia Community Bank, and Sierra Vista Bank respectively, over the net amounts assigned to assets acquired and liabilities assumed in the transactions accounted for under the purchase method of accounting. The value of goodwill is ultimately derived from the Company’s ability to generate net earnings after the acquisitions and is not deductible for tax purposes. T he fair values of assets acquired and liabilities assumed are subject to adjustment during the first twelve months after the acquisition date if additional information becomes available to indicate a more accurate or appropriate value for an asset or liability. A decline in net earnings could be indicative of a decline in the fair value of goodwill and result in impairment. For that reason, goodwill is assessed at least annually for impairment. The Company has selected September 30 as the date to perform the annual impairment test. As of September 30, 2017, management assessed qualitative factors including performance trends and noted no factors indicating goodwill impairment. Goodwill is also tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the Company below its carrying amount. No such events or circumstances arose during the first nine months of 2017 . The intangible assets at September 30, 2017 represent the estimated fair value of the core deposit relationships acquired in the acquisition of Sierra Vista Bank in 2016 of $508,000 and the 2013 acquisition of Visalia Community Bank of $1,365,000 . Core deposit intangibles are being amortized by the straight-line method (which approximates the effective interest method) over an estimated life of ten years from the date of acquisition. The carrying value of intangible assets at September 30, 2017 was $1,243,000 net of $630,000 in accumulated amortization expense. Management evaluates the remaining useful lives quarterly to determine whether events or circumstances warrant a revision to the remaining periods of amortization. Based on the evaluation, no change to the remaining useful lives was required in the third quarter of 2017 . Management performed an annual impairment test on core deposit intangibles as of September 30, 2017 and determined no impairment was necessary. Amortization expense recognized was $141,000 and $102,000 for the nine month periods ended September 30, 2017 and 2016 , respectively. Amortization expense recognized was $47,000 and $34,000 for the three month periods ended September 30, 2017 and 2016 , respectively. The following table summarizes the Company’s estimated remaining core deposit intangible amortization expense for each of the next five years (in thousands): Years Ending Estimated Core Deposit Intangible Amortization 2017 $ 49 2018 188 2019 188 2020 188 2021 188 Thereafter 442 $ 1,243

Borrowing Arrangements	Borrowing Arrangements As of September 30, 2017 and December 31, 2016 , the Company had no Federal Home Loan Bank (FHLB) of San Francisco advances. FHLB advances are secured under the standard credit and securities-backed credit programs. Investment securities with amortized costs totaling $428,000 and $584,000 , and market values totaling $465,000 and $637,000 at September 30, 2017 and December 31, 2016 , respectively, were pledged under the securities-backed credit program. The Bank’s credit limit varies according to the amount and composition of the investment and loan portfolios pledged as collateral. As of September 30, 2017 , the Company had no Federal funds purchased. The Company had $400,000 in Federal funds purchased on December 31, 2016 .

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company files its income taxes on a consolidated basis with its subsidiary. The allocation of income tax expense (benefit) represents each entity’s proportionate share of the consolidated provision for income taxes. Deferred tax assets and liabilities are recognized for the tax consequences of temporary differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. On the consolidated balance sheets, net deferred tax assets are included in accrued interest receivable and other assets. The Company establishes a tax valuation allowance when it is more likely than not that a recorded tax benefit is not expected to be fully realized. The expense to create the tax valuation allowance is recorded as an additional income tax expense in the period the tax valuation allowance is created. Effective January 1, 2017, the Company adopted ASU 2016-09 “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” which resulted in the recognition of $0 and $104,000 in excess tax benefits related to the exercise of stock options during the three and nine months ended September 30, 2017 . Accounting for uncertainty in income taxes - The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as a component of tax expense in the consolidated statements of income. As of September 30, 2017 and December 31, 2016 , the reserve for uncertain tax positions attributable to tax deductions related to enterprise zone activities in California was $197,000 and $298,000 , respectively. The Company does not expect the total amount of unrecognized tax benefits to significantly increase or decrease in the next 12 months.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the normal course of business, the Company is 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 balance sheets. The contract or notional amounts of these instruments reflect the extent of involvement the Company has in particular classes of financial instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for loans. Commitments to extend credit amounting to $322,070,000 and $259,415,000 were outstanding at September 30, 2017 and December 31, 2016 , respectively. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract unless waived by the Bank. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Included in commitments to extend credit are undisbursed lines of credit totaling $320,275,000 and $257,557,000 at September 30, 2017 and December 31, 2016 , respectively. Undisbursed lines of credit include credits whereby customers can repay principal and request principal advances during the term of the loan at their discretion and most expire between one and 12 months . Included in undisbursed lines of credit are commitments for the undisbursed portions of construction loans totaling $91,419,000 and $43,208,000 as of September 30, 2017 and December 31, 2016 , respectively. These commitments are agreements to lend to customers, subject to meeting certain construction progress requirements established in the contracts. The underlying construction loans have fixed expiration dates. Standby letters of credit and financial guarantees amounting to $1,795,000 and $1,858,000 were outstanding at September 30, 2017 and December 31, 2016 , respectively. Standby letters of credit and financial guarantees are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing arrangements. Most standby letters of credit and guarantees carry a one year term or less. The fair value of the liability related to these standby letters of credit, which represents the fees received for their issuance, was not significant at September 30, 2017 or December 31, 2016 . The Company recognizes these fees as revenue over the term of the commitment or when the commitment is used. The Company generally requires collateral or other security to support financial instruments with credit risk. Management does not anticipate any material loss will result from the outstanding commitments to extend credit, standby letters of credit and financial guarantees. At September 30, 2017 and December 31, 2016 , the balance of a contingent allocation for probable loan loss experience on unfunded obligations was $225,000 and $125,000 , respectively. The contingent allocation for probable loan loss experience on unfunded obligations is calculated by management using an appropriate, systematic, and consistently applied process. While related to credit losses, this allocation is not a part of the allowance for credit losses and is considered separately as a liability for accounting and regulatory reporting purposes, and is included in Other Liabilities on the Company’s balance sheet. The Company is subject to legal proceedings and claims which arise in the ordinary course of business. In the opinion of management, the amount of ultimate liability with respect to such actions will not materially affect the consolidated financial position or consolidated results of operations of the Company.

Earnings Per Share

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share (EPS), which excludes dilution, is computed by dividing income 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 securities or other contracts to issue common stock, such as stock options, stock appreciation rights settled in stock or restricted stock awards, result in the issuance of common stock which shares in the earnings of the Company. A reconciliation of the numerators and denominators of the basic and diluted EPS computations is as follows: Basic Earnings Per Share For the Three Months For the Nine Months (In thousands, except share and per share amounts) 2017 2016 2017 2016 Net Income $ 4,494 $ 3,114 $ 13,691 $ 12,575 Less: Preferred stock dividends and accretion — — — — Net income available to common shareholders $ 4,494 $ 3,114 $ 13,691 $ 12,575 Weighted average shares outstanding 12,208,313 10,984,141 12,183,363 10,969,633 Basic earnings per share $ 0.37 $ 0.28 $ 1.12 $ 1.15 Diluted Earnings Per Share For the Three Months For the Nine Months (In thousands, except share and per share amounts) 2017 2016 2017 2016 Net income available to common shareholders $ 4,494 $ 3,114 $ 13,691 $ 12,575 Weighted average shares outstanding 12,208,313 10,984,141 12,183,363 10,969,633 Effect of dilutive stock options 116,941 108,533 132,487 98,412 Weighted average shares of common stock and common stock equivalents 12,325,254 11,092,674 12,315,850 11,068,045 Diluted earnings per share $ 0.36 $ 0.28 $ 1.11 $ 1.14 No outstanding options or restricted stock awards were anti-dilutive for the nine months ended September 30, 2017 . Outstanding options and restricted stock of 54,650 were not factored into the calculation of dilutive stock options for the nine months ended September 30, 2016 , because they were anti-dilutive. During the three-month period ended September 30, 2017 no options or restricted stock awards were anti-dilutive. During the three-month period ended September 30, 2016 , 45,800 options or restricted stock awards were not factored into the calculation because they were anti-dilutive.

Share-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	Share-Based Compensation The Company has three share-based compensation plans as described below. Share-based compensation cost recognized for those plans was $310,000 and $196,000 for the nine months ended September 30, 2017 and 2016 , respectively. For the quarters ended September 30, 2017 and 2016 , share-based compensation was $77,000 and $89,000 , respectively. The recognized tax benefits for the share-based compensation expense, forfeitures of restricted stock, and exercise of stock options, resulted in the recognition of $102,000 and $38,000 , respectively, for the nine month periods ended September 30, 2017 and 2016 . For the quarters ended September 30, 2017 and 2016 , recognized tax benefits were $0 and $10,000 , respectively. The Company adopted ASU 2016-09 “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” during the nine months ended September 30, 2017 . The Central Valley Community Bancorp 2000 Stock Option Plan (2000 Plan) expired on November 15, 2010. The Central Valley Community Bancorp 2005 Omnibus Incentive Plan (2005 Plan) was adopted in May 2005 and expired March 16, 2015. The Central Valley Community Bancorp 2015 Omnibus Incentive Plan (2015 Plan) was adopted in May 2015. The plan provides for awards in the form of incentive stock options, non-statutory stock options, stock appreciation rights, and restricted stock. The plan also allows for performance awards that may be in the form of cash or shares of the Company, including restricted stock. Outstanding arrangements to issue shares under this plan including options, will continue in force until expiration according to their respective terms. Effective June 2, 2017, the Company adopted an Employee Stock Purchase Plan (ESPP) whereby our employees may purchase Company common stock through payroll deductions of between one percent and 15 percent of pay in each pay period. Shares are purchased at the end of the six -month offering period at a 10 percent discount from the closing market price on the last day of each offering period. The Company has reserved 500,000 common shares to be set aside for the ESPP, and there were 500,000 shares available for future purchase under the plan as of September 30, 2017 . Stock Option Plan The Company bases the fair value of the options granted on the date of grant using a Black-Scholes Merton option pricing model that uses assumptions based on expected option life and the level of estimated forfeitures, expected stock volatility, risk free interest rate, and dividend yield. The expected term and level of estimated forfeitures of the Company’s options are based on the Company’s own historical experience. Stock volatility is based on the historical volatility of the Company’s stock. The risk-free rate is based on the U. S. Treasury yield curve for the periods within the contractual life of the options in effect at the time of grant. The compensation cost for options granted is based on the weighted average grant date fair value per share. No options to purchase shares of the Company’s common stock were granted during the nine month periods ended September 30, 2017 and 2016 . A summary of the combined activity of the Company’s stock option compensation plans for the nine month periods ended September 30, 2017 follows (in thousands, except per share amounts): Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (In thousands) Options outstanding at January 1, 2017 202,215 $ 6.87 Options exercised (69,965 ) $ 6.75 Options forfeited (1,380 ) $ 8.02 Options outstanding at September 30, 2017 130,870 $ 6.92 3.84 $ 2,012 Options vested or expected to vest at September 30, 2017 130,850 $ 6.92 3.84 $ 2,012 Options exercisable at September 30, 2017 130,670 $ 6.92 3.84 $ 2,010 Information related to the stock option plan is as follows (in thousands): For the Three Months For the Nine Months 2017 2016 2017 2016 Intrinsic value of options exercised $ 13 $ 71 $ 964 $ 197 Cash received from options exercised $ 7 $ 48 $ 473 $ 208 Excess tax benefit realized for option exercises $ — $ 10 $ 104 $ 19 As of September 30, 2017 , there was no remaining unrecognized compensation cost related to nonvested stock options granted under all plans. The total fair value of options vested was $46,000 and $51,000 during the nine months ended September 30, 2017 and 2016 , respectively. Restricted Common Stock Awards The 2005 Plan and 2015 Plan provide for the issuance of restricted common stock to directors and officers. Restricted common stock grants typically vest over a five -year period. Restricted common stock (all of which are shares of our common stock) is subject to forfeiture if employment terminates prior to vesting. The cost of these awards is recognized over the vesting period of the awards based on the fair value of our common stock on the date of the grant. The following table summarizes restricted stock activity for the nine month period ended September 30, 2017 as follows: Shares Weighted Average Grant-Date Fair Value Nonvested outstanding shares at January 1, 2017 93,501 $ 13.35 Granted — $ — Vested (27,373 ) $ 13.34 Forfeited (1,590 ) $ 14.10 Nonvested outstanding shares at September 30, 2017 64,538 $ 13.34 There were no grants of restricted stock during the quarter ended September 30, 2017 or 2016. During the nine -month period ended September 30, 2017 , no shares of restricted common stock were granted from outstanding grants under the 2005 and 2015 Plans. During the nine -month period ended September 30, 2016 , 54,650 shares of restricted common stock were granted from outstanding grants under the 2005 and 2015 Plan. The restricted common stock had a fair market value of $14.10 per share on the date of grant during the nine -month period ended September 30, 2016 . These restricted common stock awards vest 20% after Year 1, and thereafter, 20% of the remaining restricted stock will vest on each anniversary of the initial award commencement date and will be fully vested on the fifth such anniversary. As of September 30, 2017 , there were 64,538 shares of restricted stock that are nonvested and expected to vest. As of September 30, 2017 , there was $736,000 of total unrecognized compensation cost related to nonvested restricted common stock awards. Restricted stock compensation expense is recognized on a straight-line basis over the vesting period. This cost is expected to be recognized over a weighted-average remaining period of 3.06 years and will be adjusted for subsequent changes in estimated forfeitures. Restricted common stock awards had an intrinsic value of $1,439,000 at September 30, 2017 .

Subsequent Events	Subsequent Events On October 18, 2017, the board of directors declared a $0.06 per share cash dividend payable on November 17, 2017 to shareholders of record as of November 3, 2017. Effective October 1, 2017, The Company and Folsom Lake Bank, headquarter in Folsom, California completed a merger under which Folsom Lake Bank (“Folsom”), with three full-service offices in Folsom, Rancho Cordova, and Roseville merged with and into Central Valley Community Bancorp’s subsidiary, Central Valley Community Bank, in an all-stock transaction. Folsom’s assets (unaudited) as of September 30, 2017 totaled approximately $197.3 million . The acquired assets and liabilities will be recorded at fair value at the date of acquisition and will be reflected in the Company’s December 31, 2017 financial statements. The Company also expects to record goodwill and a core deposit intangible related to this transaction, but those amounts are not yet known as the initial fair value accounting is incomplete. The goodwill will not be deductible for tax purposes. Under the terms of the merger agreement, the Company issued 1,276,888 shares of common stock to the former shareholders of Folsom.

Accounting Policies [Abstract]
Basis of Accounting	The interim unaudited condensed consolidated financial statements of Central Valley Community Bancorp and subsidiary have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the SEC). These interim condensed consolidated financial statements include the accounts of Central Valley Community Bancorp and its wholly owned subsidiary Central Valley Community Bank (the Bank) (collectively, the Company). All significant intercompany accounts and transactions have been eliminated in consolidation. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) have been omitted. The Company believes that the disclosures are adequate to make the information presented not misleading. These interim unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s 2016 Annual Report to Shareholders on Form 10-K. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the Company’s financial position at September 30, 2017 , and the results of its operations for the three and nine months ended September 30, 2017 and 2016 and its cash flows for the nine month interim periods ended September 30, 2017 and 2016 have been included. The results of operations for interim periods are not necessarily indicative of results for the full year. The preparation of these interim unaudited condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Segment Reporting	Management has determined that since all of the banking products and services offered by the Company are available in each branch of the Bank, all branches are located within the same economic environment, and management does not allocate resources based on the performance of different lending or transaction activities, it is appropriate to aggregate the Bank branches and report them as a single operating segment.
Concentration of Credit Risk	No customer accounts for more than 10 percent of revenues for the Company or the Bank.
Impact of New Financial Accounting Standards	Impact of New Financial Accounting Standards: FASB Accounting Standards Update (ASU) 2016-09 - Revenue from Contracts with Customers (Topic 606): Revenue from Contracts with Customers was issued in May 2014 . This ASU is the result of a joint project initiated by the FASB and the International Accounting Standards Board (IASB) to clarify the principles for recognizing revenue, and to develop common revenue standards and disclosure requirements that would: (1) remove inconsistencies and weaknesses in revenue requirements; (2) provide a more robust framework for addressing revenue issues; (3) improve comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets; (4) provide more useful information to users of financial statements through improved disclosures; and (5) simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. The guidance affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets. The core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides steps to follow to achieve the core principle. An entity should disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Qualitative and quantitative information is required with regard to contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. This ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods therein, with early adoption permitted for reporting periods beginning after December 15, 2016. The Company plans to adopt ASU 2014-09 on January 1, 2018 utilizing the modified retrospective approach. Since the guidance does not apply to revenue associated with financial instruments such as loans and investments, which are accounted for under other provisions of GAAP, we do not expect it to impact interest income, our largest component of income. The Company is currently performing an overall assessment of revenue streams potentially affected by the ASU, including certain deposit related fees and interchange fees, to determine the potential impact of this guidance on our consolidated financial statements. FASB Accounting Standards Update (ASU) 2016-01 - Financial Instruments - Overall (Subtopic 825-10) : Recognition and Measurement of Financial Assets and Financial Liabilities, was issued January 2016. The main provisions of the update are to eliminate the available-for-sale classification of accounting for equity securities and to adjust the fair value disclosures for financial instruments carried at amortized costs such that the disclosed fair values represent an exit price as opposed to an entry price. The provisions of this update will require that equity securities be carried at fair market value on the balance sheet and any periodic changes in value will be adjustments to the income statement. A practical expedient is provided for equity securities without a readily determinable fair value, such that these securities can be carried at cost less any impairment. ASU No. 2016-01 is effective for interim and annual reporting periods beginning after December 15, 2017. The Company has performed a preliminary evaluation of the provisions of ASU No. 2016-01 and based on this evaluation, has determined that ASU No. 2016-01 is not expected to have a material impact on the Company’s financial position, results of operations or its cash flows. FASB Accounting Standards Update (ASU) 2016-02 - Leases - Overall (Subtopic 845), was issued February 2016. The update requires all leases, with the exception of short-term leases that have contractual terms of no greater than one year, to be recorded on the balance sheet. Under the provisions of the update, leases classified as operating will be reflected on the balance sheet with the recognition of both a right-of-use asset and a lease liability. Under the update, a distinction will exist between finance and operating type leases and the rules for determining which classification a lease will fall into are similar to existing rules. For public business entities, the amendments of this update are effective for interim and annual periods beginning after December 15, 2018. The update requires a modified retrospective transition under which comparative balance sheets from the earliest historical period presented will be revised to reflect what the financials would have looked like were the provisions of the update applied consistently in all prior periods. The Company is currently evaluating the provisions of ASU No. 2016-02 and has determined that the provisions of ASU No. 2016-02 will result in an increase in assets to recognize the present value of the lease obligations with a corresponding increase in liabilities; however, the Company does not expect this to have a material impact on the Company’s results of operations or cash flows. FASB Accounting Standards Update (ASU) 2016-09 - Compensation - Stock Compensation (Subtopic 718) : Improvements to Employee Share-Based Payment Accounting, was issued March 2016. T his ASU includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. Some of the key provisions of this new ASU include: (1) companies will no longer record excess tax benefits and certain tax deficiencies in additional paid-in capital (“APIC”). Instead, they will record all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement, and APIC pools will be eliminated. The guidance also eliminates the requirement that excess tax benefits be realized before companies can recognize them. In addition, the guidance requires companies to present excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity; (2) increase the amount an employer can withhold to cover income taxes on awards and still qualify for the exception to liability classification for shares used to satisfy the employer’s statutory income tax withholding obligation. The new guidance will also require an employer to classify the cash paid to a tax authority when shares are withheld to satisfy its statutory income tax withholding obligation as a financing activity on its statement of cash flows (current guidance did not specify how these cash flows should be classified); and (3) permit companies to make an accounting policy election for the impact of forfeitures on the recognition of expense for share-based payment awards. Forfeitures can be estimated, as required today, or recognized when they occur. ASU No. 2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016. Early adoption was permitted, but all of the guidance must be adopted in the same period. Effective January 1, 2017, the Company adopted ASU 2016-09 “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” including the election to continue to treat option forfeitures on an expected basis and to provide cash flow disclosures on a prospective basis. During the three and nine months ended September 30, 2017 the adoption of this standard resulted in the recognition of $0 and $104,000 , respectively in excess tax benefits related to the exercise of stock options during the period. FASB Accounting Standards Update (ASU) 2016-13 - Measurement of Credit Losses on Financial Instruments (Subtopic 326) : Financial Instruments - Credit Losses, commonly referred to as “CECL,” was issued June 2016. The provisions of the update eliminate the probable initial recognition threshold under current GAAP which requires reserves to be based on an incurred loss methodology. Under CECL, reserves required for financial assets measured at amortized cost will reflect an organization’s estimate of all expected credit losses over the contractual term of the financial asset and thereby require the use of reasonable and supportable forecasts to estimate future credit losses. Because CECL encompasses all financial assets carried at amortized cost, the requirement that reserves be established based on an organization’s reasonable and supportable estimate of expected credit losses extends to held to maturity (“HTM”) debt securities. Under the provisions of the update, credit losses recognized on available for sale (“AFS”) debt securities will be presented as an allowance as opposed to a write-down. In addition, CECL will modify the accounting for purchased loans, with credit deterioration since origination, so that reserves are established at the date of acquisition for purchased loans. Under current GAAP a purchased loan’s contractual balance is adjusted to fair value through a credit discount and no reserve is recorded on the purchased loan upon acquisition. Since under CECL reserves will be established for purchased loans at the time of acquisition, the accounting for purchased loans is made more comparable to the accounting for originated loans. Finally, increased disclosure requirements under CECL require organizations to present the currently required credit quality disclosures disaggregated by the year of origination or vintage. The FASB expects that the evaluation of underwriting standards and credit quality trends by financial statement users will be enhanced with the additional vintage disclosures. For public business entities that are SEC filers, the amendments of the update will become effective beginning January 1, 2020. While the Company is currently evaluating the provisions of ASU No. 2016-13 to determine the potential impact the new standard will have on the Company’s Consolidated Financial Statements, it has taken steps to prepare for the implementation when it becomes effective, such as forming an internal task force, gathering pertinent data, consulting with outside professionals, and evaluating its current IT systems. Management expects to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the first reporting period in which the new standard is effective, but cannot yet estimate the magnitude of the one-time adjustment or the overall impact of the new guidance on the Company’s financial position, results of operations or cash flows. FASB Accounting Standards Update (ASU) 2017-04 - Intangibles Goodwill and Other (Subtopic 350) : Simplifying the Test for Goodwill Impairment, was issued January 2017. The provisions of the update eliminate the existing second step of the goodwill impairment test which provides for the allocation of reporting unit fair value among existing assets and liabilities, with the net leftover amount representing the implied fair value of goodwill. In replacement of the existing goodwill impairment rule, the update will provide that impairment should be recognized as the excess of any of the reporting unit’s goodwill over the fair value of the reporting unit. Under the provisions of this update, the amount of the impairment is limited to the carrying value of the reporting unit’s goodwill. For public business entities that are SEC filers, the amendments of the update will become effective in fiscal years beginning after December 15, 2019. FASB Accounting Standards Update (ASU) 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) : Premium Amortization on Purchased Callable Debt Securities, was issued March 2017. The provisions of the update require premiums recognized upon the purchase of callable debt securities to be amortized to the earliest call date in order to avoid losses recognized upon call. For public business entities that are SEC filers, the amendments of the update will become effective in fiscal years beginning after December 15, 2018. Management does not expect the requirements of this update to have a material impact on the Company’s financial position, results of operations or cash flows. FASB Accounting Standards Update (ASU) 2017-09 - Compensation - Stock Compensation (Subtopic 718) : Scope of Modification Accounting, was issued May 2017. The amendments in ASU 2017-09 provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. An entity should account for the effects of a modification unless all of the following conditions are met: the fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified; the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; and the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments in this Update should be applied prospectively to an award modified on or after the adoption date. The amendments in this Update are effective for annual periods, and interim periods within those annual periods, beginning after December 31, 2017. Early adoption is permitted, including adoption in any interim period. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements. FASB Accounting Standards Update (ASU) 2017-12 - Derivatives and Hedging (Topic 815) ; T argeted Improvements to Accounting for Hedging Activities was issued August 2017. This ASU’s objectives are to (1) improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities by better aligning the entity’s financial reporting for hedging relationships with those risk management activities; and (2) reduce the complexity of and simplify the application of hedge accounting by preparers. ASU No. 2017-12 is effective for interim and annual reporting periods beginning after December 15, 2018; early adoption is permitted. The Company currently does not designate any derivative financial instruments as formal hedging relationships, and therefore, does not utilize hedge accounting. However, the Company is currently evaluating this ASU to determine whether its provisions will enhance the Company’s ability to employ risk management strategies, while improving the transparency and understanding of those strategies for financial statement users.

The Company estimates the amount and timing of expected cash flows for each loan and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan’s contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. Loans acquired during each year for which it was probable at acquisition that all contractually required payments would not be collected are as follows (in thousands): September 30, 2017 December 31, 2016 Contractually required payments receivable on PCI loans at acquisition: Commercial $ — $ 982 Total $ — $ 982 Cash flows expected to be collected at acquisition $ — $ 693 Fair value of acquired loans at acquisition $ — $ 631 Certain of the loans acquired by the Company that are within the scope of Topic ASC 310-30 are not accounted for using the income recognition model of the Topic because the Company cannot reliably estimate cash flows expected to be collected.
