Notes to Financial Statements
Significant Accounting Policies [Text Block]	NOTE 1 Nature of Operations On July 3, 2008 one The consolidated financial statements include the accounts of Bancorp and its wholly-owned bank subsidiary. All material intercompany transactions have been eliminated. In the opinion of Management, the consolidated financial statements contain all adjustments necessary to present fairly the financial position, results of operations, changes in shareholders’ equity and cash flows. All adjustments are of a normal, recurring nature. Oak Valley Community Bank is a California State chartered bank. The Company was incorporated under the laws of the state of California on May 31, 1990, May 28, 1991. On December 23, 2015, 2). $7.3 The preparation of 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 period. Significant accounting estimates reflected in the Company’s consolidated financial statements include the allowance for loan losses, accounting for income taxes, fair value measurements, and the determination, recognition and measurement of impaired loans. Actual results could differ from these estimates. A summary of the significant accounting policies applied in the preparation of the accompanying consolidated financial statements follows. Subsequent events — December 31, 2016for Cash and cash equivalents — three one Securities available for sale — Investments with fair values that are less than amortized cost are considered impaired. Impairment may Other real estate owned — Loans originated Loan fees net of certain direct costs of origination are deferred and amortized, as an adjustment to interest yield, over the estimated life of the loan. Loans on which the accrual of interest has been discontinued are designated as non-accrual loans. Accrual of interest on loans is discontinued either when reasonable doubt exists as to the full and timely collection of interest or principal or when a loan becomes contractually past due by ninety Allowance for loan losses The allowance for loan losses is evaluated on a regular basis by management and is based on management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses. Such agencies may The allowance consists of specific, general, and unallocated components. The specific component relates to loans that are classified as impaired. Impaired loans, as defined, are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. The general component relates to non-impaired loans and is based on historical loss experience adjusted for qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. The Company considers a loan impaired when it is probable that all amounts of principal and interest due, according to the contractual terms of the loan agreement, will not be collected. Interest income is recognized on impaired loans in the same manner as non-accrual loans. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The method for calculating the allowance for unfunded loan commitments is based on an allowance percentage which is less than other outstanding loan types because they are at a lower risk level. This allowance percentage is evaluated by management periodically and is applied to the total undisbursed loan commitment balance to calculate the allowance for off-balance-sheet commitments. The Company considers a loan to be a troubled debt restructure (“TDR”) when the Company has granted a concession and the borrower is experiencing financial difficulty. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy. A TDR loan is kept on non-accrual status until the borrower has paid for six Acquired Loans and Leases — Loans and leases acquired through purchase or through a business combination are recorded at their fair value at the acquisition date. Credit discounts, which reflect estimates of credit losses, expected to be incurred over the life of the loan, are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition for evidence of deterioration in credit quality since their origination to determine if it is probable the Company will be unable to collect all contractually required payments. These loans are classified as Purchased Credit Impaired (“PCI”) loans, while all other acquired loans are classified as non-PCI loans. The Company has elected to account for PCI loans at the individual loan level. The Company estimates the amount and timing of expected cash flows for each loan. The expected cash flow in excess of the loan's carrying value, is referred to as the accretable yield, and is recorded as interest income over the remaining expected life of the loan. The excess of the loan's contractual principal and interest over expected cash flows is referred to as the non-accretable difference, and is representative of contractual amounts the Company does not expect to collect. The non-accretable difference is not recorded in the Company's consolidated financial statements. Quarterly, management performs an evaluation of expected future cash flows for PCI loans. If current expectations of future cash flows are less than management's previous expectations, other than due to decreases in interest rates and prepayment assumptions, an allowance for loan and leases losses is recorded with a charge to provision for loan and lease losses. If there has been a probable and significant increase in expected future cash flows over that which was previously expected, the Company first For acquired loans not considered credit impaired (“non-PCI”), we recognize the entire fair value discount accretion to interest income, based on contractual cash flows using an effective interest rate method for term loans, and on a straight line basis for revolving lines. When a non-PCI loan is placed on non-accrual status subsequent to acquisition, accretion stops until the loan is returned to accrual status. The level of accretion on non-PCI loans varies from period to period due to maturities and early pay-offs of these loans during the reporting periods. Subsequent to acquisition, if the probable and estimable losses for non-PCI loans exceed the amount of the remaining unaccreted discount, the excess is established as an allowance for loan losses. All acquired loans were acquired in acquisitions and do not represent loans purchased from third Premises and equipment — Building (in years) 31.5 Equipment (in years) 3 – 12 Furniture and fixtures (in years) 3 – 7 Leasehold improvements (in years) 5 – 15 Automobiles (in years) 3 – 5 Leasehold improvements are amortized over the lesser of the useful life of the asset or the remaining term of the lease. The straight-line method of depreciation is followed for all assets for financial reporting purposes, but accelerated methods are used for tax purposes. Deferred income taxes have been provided for the resulting temporary differences. Income taxes — The Company files income tax returns in the U.S. federal jurisdiction, and the state of California. With few exceptions, the Company is no longer subject to U.S. federal tax examinations by tax authorities for years before 2013 2012. Transfers of financial assets — (1) (2) (3) Advertising costs — $199,000 $189,000 December 31, 2016 2015, Comprehensive income — December 31, 2016 2015, $31,000 $121,000 Federal Reserve Bank Stock Federal Reserve Bank stock represents the Company’s investment in the stock of the Federal Reserve Bank (“FRB”) and is carried at par value, which reasonably approximates its fair value. While technically these are considered equity securities, there is no market for the FRB stock. Therefore, the shares are considered as restricted investment securities. Management periodically evaluates FRB stock for other-than-temporary impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) (2) (3) (4) Federal Home Loan Bank Stock Federal Home Loan Bank stock represents the Company’s investment in the stock of the Federal Home Loan Bank of San Francisco (“FHLB”) and is carried at par value, which reasonably approximates its fair value. While technically these are considered equity securities, there is no market for the FHLB stock. Therefore, the shares are considered as restricted investment securities. Management periodically evaluates FHLB stock for other-than-temporary impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) (2) (3) (4) Earnings per common share (“EPS”) 13 (1) (2) (3) two two Stock based compensation — The fair value of each option grant is estimated as of the grant date using a binomial option-pricing model for all grants. Expected volatility is based on the historical volatility of the price of the Company’s stock. The Company uses historical data to estimate option exercise and stock option forfeiture rates within the valuation model. The expected term of options granted for the binomial model is derived from applying a historical suboptimal exercise factor to the contractual term of the grant. For binomial pricing, the risk-free rate for periods is equal to the U.S. Treasury yield at the time of grant and commensurate with the contractual term of the grant. There were no stock options granted in 2016 2015. Fair values of financial instruments — December 31, 2016 2015. Fair value measurements — may The Company has established and documented a process for determining fair value. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when developing fair value measurements. Whenever there is no readily available market data, Management uses its best estimate and assumptions in determining fair value, but these estimates involve inherent uncertainties and the application of Management's judgment. As a result, if other assumptions had been used, our recorded earnings or disclosures could have been materially different from those reflected in these financial consolidated statements.

Expected cash flows for each acquired loan were projected based on contractual cash flows adjusted for expected prepayment, expected default (i.e. probability of default and loss severity), and principal recovery. Prepayment rates were applied to the principal outstanding based on the type of loan, where appropriate. Prepayments were based on a constant prepayment rate (“CPR”) applied across the life of a loan. The annual CPRs were between 0% 5%, Non-credit-impaired loans with similar characteristics were grouped together and were treated in the aggregate when applying the discount rate on the expected cash flows. Aggregation factors considered included the type of loan and related collateral, risk classification, fixed or variable interest rate, term of loan and whether or not the loan was amortizing. See Note 5 Core Deposit Intangible The core deposit intangible represents the estimated future benefits of acquired deposits and is booked separately from the related deposits.

Commercial and industrial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and prudently expand its business. Underwriting standards are designed to promote relationship banking rather than transactional banking. Once it is determined that the borrower’s management possesses sound ethics and solid business acumen, the Company’s management examines current and projected cash flows to determine the ability of the borrower to repay their obligations as agreed. Commercial and industrial loans are primarily made based on the identified cash flows of the borrower and secondarily may may may may may Commercial real estate loans are subject to underwriting standards and processes similar to commercial and industrial loans, in addition to those of real estate loans. These loans are viewed primarily as cash flow loans and secondarily may third December 31, 2016, 40.9% With respect to loans to developers and builders that are secured by non-owner occupied properties that the Company may may may The Company originates consumer loans utilizing a computer-based credit scoring analysis to supplement the underwriting process. To monitor and manage consumer loan risk, policies and procedures are developed and modified, as needed, jointly by line and staff personnel. This activity, coupled with relatively small loan amounts that are spread across many individual borrowers, minimizes risk. Additionally, trend and outlook reports are reviewed by management on a regular basis. Underwriting standards for home equity loans follow bank policy, which include, but are not limited to, a maximum loan-to-value percentage of 80%, 36% 42%, The Company maintains an independent loan review department that reviews and validates the credit risk program on a periodic basis. Results of these reviews are presented to management. The loan review process complements and reinforces the risk identification and assessment decisions made by lenders and credit personnel, as well as the Company’s policies and procedures. Purchased Credit-Impaired (“PCI”) Loans. 310 30 For acquired loans not considered credit-impaired, the difference between the contractual amounts due (principal amount) and the fair value is accounted for subsequently through accretion. We recognize discount accretion based on the acquired loan’s contractual cash flows using an effective interest rate method. The accretion is recognized through the net interest margin.

The cash flows expected to be collected are updated each quarter based on current assumptions regarding default rates, loss severities, and other factors that are reflective of current market conditions. Probable decreases in expected cash flows after acquisition result in the recognition of impairment as a specific allowance for loan losses or a charge-off to the allowance. The nonaccretable difference represents the difference between the undiscounted contractual cash flows and the undiscounted expected cash flows, and also reflects the estimated credit losses in the acquired loan portfolio at the acquisition date and can fluctuate due to changes in expected cash flows during the life of the PCI loans.

Portions of the allowance may The Company’s allowance for loan losses consists of three 310 450 450 The allowances established for probable losses on specific loans are based on a regular analysis and evaluation of problem loans. Loans are classified based on an internal credit risk grading process that evaluates, among other things: (i) the obligor’s ability to repay; (ii) the underlying collateral, if any; and (iii) the economic environment and industry in which the borrower operates. This analysis is performed at the relationship manager level for all commercial loans. When a loan has a calculated grade of 5 Historical valuation allowances are calculated based on the historical loss experience of specific types of loans and the internal risk grade of such loans at the time they were charged-off. The Company calculates historical loss ratios for pools of similar loans with similar characteristics based on the proportion of actual charge-offs experienced to the total population of loans in the pool. The historical loss ratios are periodically updated based on actual charge-off experience. A historical valuation allowance is established for each pool of similar loans based upon the product of the historical loss ratio and the total dollar amount of the loans in the pool. The Company’s pools of similar loans include similarly risk-graded groups of commercial and industrial loans, commercial real estate loans, consumer real estate loans and consumer and other loans. General valuation allowances are based on general economic conditions and other qualitative risk factors both internal and external to the Company. In general, such valuation allowances are determined by evaluating, among other things: (i) the experience, ability and effectiveness of the Company’s lending management and staff; (ii) the effectiveness of the Company’s loan policies, procedures and internal controls; (iii) changes in asset quality; (iv) changes in loan portfolio volume; (v) the composition and concentrations of credit; (vi) the impact of competition on loan structuring and pricing; (vii) the effectiveness of the internal loan review function; (viii) the impact of environmental risks on portfolio risks; and (ix) the impact of rising interest rates on portfolio risk. Management evaluates the degree of risk that each one Included in the general valuation allowances are allocations for groups of similar loans with risk characteristics that exceed certain concentration limits established by management. Concentration risk limits have been established, among other things, for certain industry concentrations, large balance and highly leveraged credit relationships that exceed specified risk grades, and loans originated with policy exceptions that exceed specified risk grades.

Regulatory Capital Requirements under Banking Regulations [Text Block]	NOTE 2 1 — REGULATORY MATTERS The Bank and the Company are subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory — and possibly additional discretionary — actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices.

Loans and Leases Receivable, Real Estate Acquired Through Foreclosure, Policy [Policy Text Block]	Other real estate owned —
Finance, Loans and Leases Receivable, Policy [Policy Text Block]	Loans originated Loan fees net of certain direct costs of origination are deferred and amortized, as an adjustment to interest yield, over the estimated life of the loan. Loans on which the accrual of interest has been discontinued are designated as non-accrual loans. Accrual of interest on loans is discontinued either when reasonable doubt exists as to the full and timely collection of interest or principal or when a loan becomes contractually past due by ninety
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for loan losses The allowance for loan losses is evaluated on a regular basis by management and is based on management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses. Such agencies may The allowance consists of specific, general, and unallocated components. The specific component relates to loans that are classified as impaired. Impaired loans, as defined, are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. The general component relates to non-impaired loans and is based on historical loss experience adjusted for qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. The Company considers a loan impaired when it is probable that all amounts of principal and interest due, according to the contractual terms of the loan agreement, will not be collected. Interest income is recognized on impaired loans in the same manner as non-accrual loans. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The method for calculating the allowance for unfunded loan commitments is based on an allowance percentage which is less than other outstanding loan types because they are at a lower risk level. This allowance percentage is evaluated by management periodically and is applied to the total undisbursed loan commitment balance to calculate the allowance for off-balance-sheet commitments. The Company considers a loan to be a troubled debt restructure (“TDR”) when the Company has granted a concession and the borrower is experiencing financial difficulty. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy. A TDR loan is kept on non-accrual status until the borrower has paid for six
Finance Loans and Leases Receivable Acquired, Policy [Policy Text Block]	Acquired Loans and Leases — Loans and leases acquired through purchase or through a business combination are recorded at their fair value at the acquisition date. Credit discounts, which reflect estimates of credit losses, expected to be incurred over the life of the loan, are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition for evidence of deterioration in credit quality since their origination to determine if it is probable the Company will be unable to collect all contractually required payments. These loans are classified as Purchased Credit Impaired (“PCI”) loans, while all other acquired loans are classified as non-PCI loans. The Company has elected to account for PCI loans at the individual loan level. The Company estimates the amount and timing of expected cash flows for each loan. The expected cash flow in excess of the loan's carrying value, is referred to as the accretable yield, and is recorded as interest income over the remaining expected life of the loan. The excess of the loan's contractual principal and interest over expected cash flows is referred to as the non-accretable difference, and is representative of contractual amounts the Company does not expect to collect. The non-accretable difference is not recorded in the Company's consolidated financial statements. Quarterly, management performs an evaluation of expected future cash flows for PCI loans. If current expectations of future cash flows are less than management's previous expectations, other than due to decreases in interest rates and prepayment assumptions, an allowance for loan and leases losses is recorded with a charge to provision for loan and lease losses. If there has been a probable and significant increase in expected future cash flows over that which was previously expected, the Company first For acquired loans not considered credit impaired (“non-PCI”), we recognize the entire fair value discount accretion to interest income, based on contractual cash flows using an effective interest rate method for term loans, and on a straight line basis for revolving lines. When a non-PCI loan is placed on non-accrual status subsequent to acquisition, accretion stops until the loan is returned to accrual status. The level of accretion on non-PCI loans varies from period to period due to maturities and early pay-offs of these loans during the reporting periods. Subsequent to acquisition, if the probable and estimable losses for non-PCI loans exceed the amount of the remaining unaccreted discount, the excess is established as an allowance for loan losses. All acquired loans were acquired in acquisitions and do not represent loans purchased from third

The straight-line method of depreciation is followed for all assets for financial reporting purposes, but accelerated methods are used for tax purposes. Deferred income taxes have been provided for the resulting temporary differences.
Income Tax, Policy [Policy Text Block]	Income taxes — The Company files income tax returns in the U.S. federal jurisdiction, and the state of California. With few exceptions, the Company is no longer subject to U.S. federal tax examinations by tax authorities for years before 2013 2012.

Federal Reserve Bank Stock, Policy [Policy Text Block]	Federal Reserve Bank Stock Federal Reserve Bank stock represents the Company’s investment in the stock of the Federal Reserve Bank (“FRB”) and is carried at par value, which reasonably approximates its fair value. While technically these are considered equity securities, there is no market for the FRB stock. Therefore, the shares are considered as restricted investment securities. Management periodically evaluates FRB stock for other-than-temporary impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) (2) (3) (4)

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock based compensation — The fair value of each option grant is estimated as of the grant date using a binomial option-pricing model for all grants. Expected volatility is based on the historical volatility of the price of the Company’s stock. The Company uses historical data to estimate option exercise and stock option forfeiture rates within the valuation model. The expected term of options granted for the binomial model is derived from applying a historical suboptimal exercise factor to the contractual term of the grant. For binomial pricing, the risk-free rate for periods is equal to the U.S. Treasury yield at the time of grant and commensurate with the contractual term of the grant. There were no stock options granted in 2016 2015.

Fair Value Measurement, Policy [Policy Text Block]	Fair value measurements — may The Company has established and documented a process for determining fair value. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when developing fair value measurements. Whenever there is no readily available market data, Management uses its best estimate and assumptions in determining fair value, but these estimates involve inherent uncertainties and the application of Management's judgment. As a result, if other assumptions had been used, our recorded earnings or disclosures could have been materially different from those reflected in these financial consolidated statements.
