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. This 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); Targeted 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.
