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 2018 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 June 30, 2019, and the results of its operations and its cash flows for the six-month interim periods ended June 30, 2019 and 2018 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) 2016-02 - Leases - Overall (Subtopic 845), was issued February 2016. ASU 2016-02 will, among other things, require lessees to recognize a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 does not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model and ASC Topic 606, “Revenue from Contracts with Customers.” ASU 2016-02 was effective for us on January 1, 2019 and initially required transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. In July 2018, the FASB issued ASU 2018-11, “Leases (Topic 842) - Targeted Improvements,” which, among other things, provides an additional transition method that would allow entities to not apply the guidance in ASU 2016-02 in the comparative periods presented in the financial statements and instead recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. In December 2018, the FASB also issued ASU 2018-20, “Leases (Topic 842) - Narrow- Scope Improvements for Lessors,” which provides for certain policy elections and changes lessor accounting for sales and similar taxes and certain lessor costs. As of January 1, 2019, the Company adopted ASU 2016-02 and has recorded a right-of-use asset and lease liability of approximately $10 million on the balance sheet for its operating leases where it is a lessee. We elected to apply certain practical expedients provided under ASU 2016-02 whereby we will not reassess(i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for any existing leases. We also did not apply the recognition requirements of ASU 2016-02 to any short-term leases (as defined by related accounting guidance). We account for lease and non-lease components separately because such amounts are readily determinable under our lease contracts and because we expect this election will result in a lower impact on our balance sheet. 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. The Company has formed an internal task force that is responsible for oversight of the Company’s implementation strategy for compliance with provisions of the new standard. The Company has also established a project management governance process to manage the implementation across affected disciplines. An external provider specializing in community bank loss driver and CECL reserving model design as well as other related consulting services has been retained, and we have begun to evaluate potential CECL modeling alternatives. As part of this process, the Company has determined potential loan pool segmentation and sub-segmentation under CECL, as well as begun to evaluate the key economic loss drivers for each segment. Further, the Company has begun developing internal controls around the CECL process, data, calculations and implementation. The Company presently plans to generate and evaluate model scenarios under CECL in tandem with its current reserving processes for interim and annual reporting periods during the second half of 2019. While the Company is currently unable to reasonably estimate the impact of adopting this new guidance, management expects the impact of adoption will be significantly influenced by the composition and quality of the Company’s loans as well as the economic conditions as of the date of adoption. The Company also anticipates significant changes to the processes and procedures for calculating the reserve for credit losses and continues to evaluate the potential impact on our consolidated financial statements. 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. The Company adopted ASU 2017-04 effective during the first quarter of 2019 and it did not have a material impact on the Company’s financial position, results of operations or cash flows. 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 become effective in fiscal years beginning after December 15, 2018. The Company adopted this ASU effective January 1, 2019 and it did not have a material impact on the Company’s financial position, results of operations or cash flows. FASB Accounting Standards Update (ASU) 2018-13 - Fair Value Measurement (Subtopic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, was issued August 2018. The primary focus of ASU 2018-13 is to improve the effectiveness of the disclosure requirements for fair value measurements. The changes affect all companies that are required to include fair value measurement disclosures. In general, the amendments in ASU 2018-13 are effective for all entities for fiscal years and interim periods within those fiscal years, beginning after December 15, 2019. An entity is permitted to early adopt the removed or modified disclosures upon the issuance of ASU 2018-13 and may delay adoption of the additional disclosures, which are required for public companies only, until their effective date. Management is currently evaluating the impact these changes will have on the Company’s consolidated financial statements and disclosures.
