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 2017 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, 2018, and the results of its operations and its cash flows for the three month interim periods ended June 30, 2018 and 2017 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) 2014-09 - 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 adopted 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, there was no impact to interest income, our largest component of income. The Company adopted this ASU effective January 1, 2018 and it did not have a material impact on the Company’s consolidated financial position, cash flows or results of operations. No cumulative adjustment was required upon adoption. The Company performed 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. Approximately 91% of our revenue, including all of our net interest income and a portion of our noninterest income, is out of scope of the guidance. The contracts that are in scope of the guidance are primarily related to service charges and fees on deposit accounts, debit card fees, ATM processing fees, and other service charges, commissions and fees. We have completed analyzing the individual contracts in scope and determined our revenue recognition practices within the scope of the ASU as described below did not change in any material regard upon adoption of the ASU. Service Charges on Deposit Accounts: The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance. Merchant and Debit Card Fees: The Company earns interchange fees from cardholder transactions conducted through the payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. 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 was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The impact of adoption of this ASU by the Company was not material, but did result in a reclassification of an equity investment from securities available-for-sale to equity securities. The Company was required to adopt the ASU provisions on January 1, 2018, and for those equity securities with readily determinable fair values, the Company elected the modified retrospective transition approach with a cumulative effect adjustment to the balance sheet. The impact of the adoption of this accounting standard on the Company’s consolidated financial statements will be subject to the price volatility of the equity investments. As a result of the adoption, $204,000 of after-tax unrealized losses on equity securities was reclassified on January 1, 2018, from accumulated other comprehensive income to retained earnings. In addition, the fair value disclosures for financial instruments in Note 3 are computed using an exit price notion as required by the ASU. 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) 2016-13 - 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. The Company adopted this ASU effective January 1, 2018 and it did not have a material impact on the Company’s Consolidated Financial Statements.

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 2017 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, 2018, and the results of its operations and its cash flows for the three month interim periods ended June 30, 2018 and 2017 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:

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 adopted 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, there was no impact to interest income, our largest component of income. The Company adopted this ASU effective January 1, 2018 and it did not have a material impact on the Company’s consolidated financial position, cash flows or results of operations. No cumulative adjustment was required upon adoption.

The Company performed 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. Approximately 91% of our revenue, including all of our net interest income and a portion of our noninterest income, is out of scope of the guidance. The contracts that are in scope of the guidance are primarily related to service charges and fees on deposit accounts, debit card fees, ATM processing fees, and other service charges, commissions and fees. We have completed analyzing the individual contracts in scope and determined our revenue recognition practices within the scope of the ASU as described below did not change in any material regard upon adoption of the ASU.

Service Charges on Deposit Accounts: The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance.

Merchant and Debit Card Fees: The Company earns interchange fees from cardholder transactions conducted through the payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder.

In addition, the fair value disclosures for financial instruments in Note 3 are computed using an exit price notion as required by the ASU.

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.

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) 2016-13 - 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.

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.

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.

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. The Company adopted this ASU effective January 1, 2018 and it did not have a material impact on the Company’s Consolidated Financial Statements.
