Basis of Accounting [Text Block]	NOTE 1 – BASIS OF PRESENTATION On July 3, 2008 (the “Effective Date”), a bank holding company reorganization was completed whereby Oak Valley Bancorp (“the Company”) became the parent holding company for Oak Valley Community Bank ( the “Bank”). On the Effective Date, a tax-free exchange was completed whereby each outstanding share of the Bank was converted into one share of the Company and the Bank became the sole wholly-owned subsidiary of the holding company. On December 23, 2015, the Company completed its acquisition of Mother Lode Bank (“MLB”), a California state-chartered bank headquartered in Sonora, California, in a transaction in which Mother Lode Bank was merged with and into the Bank, with the Bank as the surviving company in the transaction. The purchase price for Mother Lode Bank was approximately $7.3 million. As of the acquisition date, Mother Lode Bank’s total assets were $78.7 million and total deposits were $71.1 million. 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, and began operations in Oakdale on May 28, 1991. The Company operates branches in Oakdale, Sonora, Bridgeport, Bishop, Mammoth Lakes, Modesto, Manteca, Patterson, Turlock, Ripon, Stockton, Tracy and Escalon, California. The Bridgeport, Mammoth Lakes, and Bishop branches operate as a separate division, Eastern Sierra Community Bank. The Company’s primary source of revenue is providing loans to customers who are predominantly middle-market businesses. The consolidated financial statements include the accounts of the Company 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. 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, determination of non-accrual loans, other-than-temporary impairment of investment securities, the fair value measurements, deferred compensation plans, and the determination, recognition and measurement of impaired loans. Actual results could differ from these estimates. The interim consolidated financial statements included in this report are unaudited but reflect all adjustments which, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the interim periods presented. All such adjustments are of a normal recurring nature. The results of operations for the three and six month periods ended June 30, 2016 are not necessarily indicative of the results of a full year’s operations. Certain prior year amounts have been reclassified to conform to the current year presentation. There was no effect on net income or shareholders’ equity as a result of reclassifications. For further information, refer to the audited consolidated financial statements and footnotes included in the Company’s Form 10-K for the year ended December 31, 2015.

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	NOTE 2 – RECENT ACCOUNTING PRONOUNCEMENTS In September, 2015, the FASB issued ASU No. 2015-16, Simplifying the Accounting for Measurement Period Adjustments (Topic 805). This ASU eliminates the requirement to restate prior period financial statements for measurement period adjustments to assets acquired and liabilities assumed in a business combination. The new guidance under this update requires the cumulative impact of measurement period adjustments be recognized in the period the adjustment is determined. This update does not change what constitutes a measurement period adjustment, nor does it change the length of the measurement period. The new standard is effective for interim annual periods beginning after December 15, 2015 and should be applied prospectively to measurement period adjustments that occur after the effective date. The adoption of this update is not expected to have a material impact on the Company’s consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this ASU make improvements to GAAP related to financial instruments that include the following as applicable to us. ● Equity investments, except for those accounted for under the equity method of accounting or those that result in consolidation of the investee, are required to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. ● Simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment - if impairment exists, this requires measuring the investment at fair value. ● Eliminates the requirement for public companies to disclose the method(s) and significant assumptions used to estimate the fair value that is currently required to be disclosed for financial instruments measured at amortized cost on the balance sheet. ● Public companies will be required to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. ● Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements. ● The reporting entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity's other deferred tax assets. ASU 2016-01 is effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. This ASU will impact our financial statement disclosures, however, we do not expect this ASU to have a material impact on our financial condition or results of operations. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This ASU was issued to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities, including leases classified as operating leases under previous GAAP, on the balance sheet and requiring additional disclosures of key information about leasing arrangements. ASU 2016-02 is effective for annual periods, including interim periods within those annual periods beginning after December 15, 2018 and requires a modified retrospective approach to adoption. Early application of the amendments is permitted. We are currently evaluating the provisions of this ASU and will be monitoring developments and additional guidance to determine the potential outcome the amendments will have on our financial condition and results of operations.

Notes to Financial Statements
Business Combination Disclosure [Text Block]	NOTE 3 – ACQUISITION On December 23, 2015, in effort to expand our market presence and enhance shareholder value, the Company acquired 100% of the outstanding common shares of Mother Lode Bank ("MLB") and all unexercised options to purchase MLB common stock were cancelled, in exchange for $7,336,000 in cash (the "MLB Acquisition"). In conjunction with the MLB Acquisition, MLB was merged with and into Oak Valley Community Bank. On January 29, 2016, the two acquired MLB branches in Sonora were closed after management determined that our two existing branches in Sonora would be able to support our new customers. The assets acquired and liabilities assumed, both tangible and intangible, were recorded at their fair values as of the acquisition date in accordance with ASC 805. We have not identified additional information that existed at the acquisition date that would affect the measurement of assets acquired and liabilities assumed. Accordingly, there have been no changes in the fair value of assets acquired or liabilities assumed since the acquisition date. The acquisition was treated as a "reorganization" within the definition of section 368(a) of the Internal Revenue Code and is generally considered tax-free for U.S. federal income tax purposes. The following table reflects the estimated fair values of the assets acquired and liabilities assumed related to the MLB Acquisition: (Dollars in thousands) Acquisition Date Assets: Cash and cash equivalents $ 30,804 Loans 42,831 Core deposit intangible 1,031 Deferred tax asset 2,651 Goodwill 662 Other assets 738 Total assets acquired $ 78,717 Liabilities: Deposits: Non-interest bearing $ 36,177 Interest bearing Transaction accounts 6,112 Savings accounts 15,727 Money market accounts 7,602 Other time accounts 5,507 Total deposits 71,125 Other liabilities 256 Total liabilities assumed $ 71,381 Merger consideration $ 7,336 The following table presents the net assets acquired from MLB and the estimated fair value adjustments: (Dollars in thousands) Acquisition Date Book value of net assets acquired from Mother Lode Bank $ 4,884 Fair value adjustments: Loans (2,960 ) Reversal of Allowance for Loan Loss 1,279 Core deposit intangible asset 1,031 Other assets & liabilities, net (210 ) Total purchase accounting adjustments $ (860 ) Deferred tax asset (tax effect of purchase accounting adjustments at 41.15%) 354 DTA Carryforward 2,296 Fair value of net assets acquired from Mother Lode Bank $ 6,674 Merger consideration 7,336 Less: fair value of net assets acquired (6,674 ) Goodwill $ 662 As a result of the MLB Acquisition, we recorded $662,000 in goodwill, which represents the excess of the total purchase price paid over the fair value of the assets acquired, net of the fair values of liabilities assumed. Goodwill mainly reflects expected value created through the combined operations of MLB and the Company. At December 31, 2015, we determined that the fair value of our traditional community banking activities (provided through our branch network) exceeded the carrying amount. Therefore, no impairment on goodwill has been recorded. The following is a description of the methods used to determine the fair values of significant assets and liabilities at acquisition date presented above. Loans The fair values for acquired loans were developed based upon the present values of the expected cash flows utilizing market-derived discount rates. 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% and 5%, depending on the characteristics of the loan pool (e.g. construction, commercial real estate, etc.). 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 for additional information. Core Deposit Intangible The core deposit intangible represents the estimated future benefits of acquired deposits and is booked separately from the related deposits. The value of the core deposit intangible asset was determined using a discounted cash flow approach to arrive at the cost differential between the core deposits (non-maturity deposits such as transaction, savings and money market accounts) and alternative funding sources. A core deposit intangible asset of $1,031,000 was recorded on December 23, 2015, of which $40,000 and $81,000 was amortized during the three and six month periods ended June 30, 2016, respectively. The core deposit intangible is amortized on an accelerated basis over an estimated ten-year life, and it is evaluated periodically for impairment. No impairment loss was recognized as of June 30, 2016. Acquisition Related Expenses Acquisition-related expenses are recognized as incurred and continue until all systems have been converted and operational functions become fully integrated. We incurred one-time third-party acquisition-related expenses in the consolidated statements of income totaling $83,000 and $141,000 during the three and six month periods ended June 30, 2016, respectively. The conversion of the operating systems was completed in April 2016.

Management periodically evaluates each available-for-sale investment security in an unrealized loss position to determine if the impairment is temporary or other than temporary. This evaluation encompasses various factors including, the nature of the investment, the cause of the impairment, the severity and duration of the impairment, credit ratings and other credit related factors such as third party guarantees and volatility of the security’s fair value. Management has determined that no investment security is other than temporarily impaired. The unrealized losses are due primarily to interest rate changes and the Company does not intend to sell the securities and it is not likely that we will be required to sell the securities before the earlier of the forecasted recovery or the maturity of the underlying investment security. The amortized cost and estimated fair value of investment securities at June 30, 2016, by contractual maturity or call date, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Loans, Notes, Trade and Other Receivables Disclosure [Text Block]	NOTE 5 – LOANS Our customers are primarily located in Stanislaus, San Joaquin, Tuolumne, Inyo, and Mono Counties. As of June 30, 2016, approximately 78% of the Company’s loans are commercial real estate loans which include construction loans. Approximately 12% of the Company’s loans are for general commercial uses including professional, retail, and small business. Additionally, 6% of the Company’s loans are for residential real estate and other consumer loans. The remaining 4% are agriculture loans. Loan totals were as follows: (in thousands) June 30, 2016 December 31, 2015 Commercial real estate: Commercial real estate- construction $ 16,459 $ 19,363 Commercial real estate- mortgages 371,393 363,644 Land 9,478 10,239 Farmland 56,260 29,801 Commercial and industrial 65,359 63,776 Consumer 910 774 Consumer residential 35,275 32,588 Agriculture 24,640 20,847 Total loans 579,774 541,032 Less: Deferred loan fees and costs, net (2,426 ) (3,282 ) Allowance for loan losses (7,680 ) (7,356 ) Net loans $ 569,668 $ 530,394 Loan Origination/Risk Management. 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, our 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 on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial and industrial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. 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 as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The properties securing the Company’s commercial real estate portfolio are diverse in terms of type and geographic location. This diversity helps reduce the Company’s exposure to adverse economic events that affect any single market or industry. Management monitors and evaluates commercial real estate loans based on collateral, geography and risk grade criteria. As a general rule, the Company avoids financing single-purpose projects unless other underwriting factors are present to help mitigate risk. The Company also utilizes third-party experts to provide insight and guidance about economic conditions and trends affecting market areas it serves. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner occupied loans. At June 30, 2016 and December 31, 2015, commercial real estate loans equal to approximately 42.8% and 44.3%, respectively, of the outstanding principal balance of our commercial real estate loans were secured by owner-occupied properties. With respect to loans to developers and builders that are secured by non-owner occupied properties that the Company may originate from time to time, the Company generally requires the borrower to have had an existing relationship with the Company and have a proven record of success. Construction loans are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analysis of absorption and lease rates and financial analysis of the developers and property owners. Construction loans are generally based upon estimates of costs and value associated with the complete project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions and the availability of long-term financing. Agricultural production, real estate and development lending is susceptible to credit risks including adverse weather conditions, pest and disease, as well as market price fluctuations and foreign competition. Agricultural loan underwriting standards are maintained by following Company policies and procedures in place to minimize risk in this lending segment. These standards consist of limiting credit to experienced farmers who have demonstrated farm management capabilities, requiring cash flow projections displaying margins sufficient for repayment from normal farm operations along with equity injected as required by policy, as well as providing adequate secondary repayment and sponsorship including satisfactory collateral support. Credit enhancement obtained through government guarantee programs may also be used to provide further support as available. The Company originates consumer loans utilizing common underwriting criteria specified in policy. 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 1-4 family, home equity lines and loans follow bank policy, which include, but are not limited to, a maximum loan-to-value percentage of 80%, a maximum housing and total debt ratio of 36% and 42%, respectively and other specified credit and documentation requirements. 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 Bank’s policies and procedures. Purchased Credit-Impaired (“PCI”) Loans. 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 following table presents the fair value of purchased credit-impaired and other loans acquired from Mother Lode Bank as of the acquisition date: December 23, 2015 (in thousands) Purchased credit-impaired loans Other purchased loans Total Contractually required payments including interest $ 1,982 $ 44,007 $ 45,989 Less: nonaccretable difference (1,103 ) 0 (1,103 ) Cash flows expected to be collected (undiscounted) 879 44,007 44,886 Accretable yield (14 ) (2,041 ) (2,055 ) Fair value of purchased loans $ 865 $ 41,966 $ 42,831 The following table reflects the outstanding balance and related carrying value of PCI loans as of June 30, 2016 and December 31, 2015: (in thousands) June 30, 2016 December 31, 2015 Commercial real estate: Unpaid principal balance Carrying value Unpaid principal balance Carrying value Commercial real estate- construction $ 0 $ 0 $ 0 $ 0 Commercial real estate- mortgages 0 0 196 118 Land 795 286 795 269 Farmland 0 0 0 0 Commercial and industrial 529 529 794 478 Consumer 0 0 0 0 Consumer residential 0 0 0 0 Agriculture 0 0 0 0 Total purchased credit-impaired loans $ 1,324 $ 815 $ 1,785 $ 865 For the PCI loans, the accretable yield represents the excess of the cash flows expected to be collected at acquisition over the fair value of the loans at the acquisition date, and is accreted into interest income over the estimated remaining life of the purchased credit-impaired loans using the effective yield method, provided that the timing and amount of future cash flows is reasonably estimable. 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 accretable yield balance for PCI loans was $14,000 at December 31, 2015, all of which was accreted to interest income during the first quarter of 2016, as each of the PCI loans had short-term maturities. 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. Non-Accrual and Past Due Loans.

At December 31, 2015, there were 5 loans that were considered to be troubled debt restructurings, all of which are considered non-accrual totaling $3,060,000. At June 30, 2016 and December 31, 2015 there were no unfunded commitments on loans classified as a troubled debt restructures. We have allocated $680,000 and $722,000 of specific reserves to loans whose terms have been modified in troubled debt restructurings as of June 30, 2016 and December 31, 2015, respectively. The modification of the terms of such loans typically includes one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date; or a temporary payment modification in which the payment amount allocated towards principal was reduced. In some cases, a permanent reduction of the accrued interest on the loan is conceded. During the six months ended June 30, 2016, one loan was modified as troubled debt restructuring by extending the maturity date. During the three and six month periods ended June 30, 2015, the terms of two loans were modified as troubled debt restructurings by extending the maturity dates.

There were no loans modified as troubled debt restructurings within the previous twelve months and for which there was a payment default during the three and six month periods ended June 30, 2016 and 2015. A loan is considered to be in payment default once it is ninety days contractually past due under the modified terms. Loan Risk Grades – We grade loans using the following letter system: 1 Exceptional Loan 2 Quality Loan 3A Better Than Acceptable Loan 3B Acceptable Loan 3C Marginally Acceptable Loan 4 (W) Watch Acceptable Loan 5 Other Loans Especially Mentioned 6 Substandard Loan 7 Doubtful Loan 8 Loss 1. Exceptional Loan - A high level of liquidity and whose debt-servicing capacity exceeds expected obligations by a substantial margin. - Where leverage is below average for the industry and earnings are consistent or growing without severe vulnerability to economic cycles. - Also included in this rating (but not mandatory unless one or more of the preceding characteristics are missing) are loans that are fully secured and properly margined by our own time instruments or U.S. blue chip securities. To be properly margined cash collateral must be equal to, or greater than, 110% of the loan amount. 2. Quality Loan - Unquestionable debt-servicing capacity to cover all obligations in the ordinary course of business from well-defined primary and secondary sources. - Consistent strong earnings. - A solid equity base. 3A. Better than Acceptable Loan - Strong earnings with no loss in last three years and ample cash flow to service all debt well above policy guidelines. - Long term experienced management with depth and defined management succession. - The loan has no exceptions to policy. - Loan-to-value on real estate secured transactions is 10% to 20% less than policy guidelines. - Very liquid balance sheet that may have cash available to pay off our loan completely. - Little to no debt on balance sheet. 3B. Acceptable Loan - Are those where the borrower has average financial strengths, a history of profitable operations and experienced management. - Are those where the borrower can be expected to handle normal credit needs in a satisfactory manner. 3C. Marginally Acceptable Requires collateral. A credit facility where the borrower has average financial strengths, but usually lacks reliable secondary sources of repayment other than the subject collateral. Other common characteristics can include some or all of the following: minimal background experience of management, lacking continuity of management, a start-up operation, erratic historical profitability (acceptable reasons-well identified), lack of or marginal sponsorship of guarantor, and government guaranteed loans. 4W Watch Acceptable 5 Other Loans Especially Mentioned (Special Mention) - The lending officer may be unable to properly supervise the credit because of an inadequate loan or credit agreement. - Questions exist regarding the condition of and/or control over collateral. - Economic or market conditions may unfavorably affect the obligor in the future. - A declining trend in the obligor’s operations or an imbalanced position in the balance sheet exists, but not to the point that repayment is jeopardized. 6 Substandard Loan 7 Doubtful Loan A proper classification of such a credit would show 40 percent substandard, 25 percent doubtful, and 35 percent loss. A credit classified as doubtful should be resolved within a ‘reasonable’ period of time. Reasonable is generally defined as the period between examinations. In other words, a credit classified doubtful at an examination should be cleared up before the next exam. However, there may be situations that warrant continuation of the doubtful classification a while longer. 8 Loss As of June 30, 2016 and December 31, 2015, there are no loans that are classified with a risk grade of 8- Loss.

The level of the allowance reflects management’s continuing evaluation of industry concentrations, specific credit risks, loan loss experience, current loan portfolio quality, present economic, political and regulatory conditions and unidentified losses inherent in the current loan portfolio. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off. While management utilizes its best judgment and information available, the ultimate adequacy of the allowance is dependent upon a variety of factors beyond the Company’s control, including, among other things, the performance of the Company’s loan portfolio, the economy, changes in interest rates and the view of the regulatory authorities toward loan classifications. The Company’s allowance for loan losses consists of three elements: (i) specific valuation allowances determined in accordance with ASC Topic 310 based on probable losses on specific loans; (ii) historical valuation allowances determined in accordance with ASC Topic 450 based on historical loan loss experience for similar loans with similar characteristics and trends, adjusted, as necessary, to reflect the impact of current conditions; and (iii) general valuation allowances determined in accordance with ASC Topic 450 based on general economic conditions and other qualitative risk factors both internal and external to the Bank and the Company. 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 or higher, a special assets officer analyzes the loan to determine whether the loan is impaired and, if impaired, the need to specifically allocate a portion of the allowance for loan losses to the loan. Specific valuation allowances are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk grade of the loan and economic conditions affecting the borrower’s industry, among other things. 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 Bank and the Company. In general, such valuation allowances are determined by evaluating, among other things: (i) the experience, ability and effectiveness of the Bank’s lending management and staff; (ii) the effectiveness of the Bank’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 of these components has on the quality of the loan portfolio on a quarterly basis. Each component is determined to have either a high, moderate or low degree of risk. The results are then input into a “general allocation matrix” to determine an appropriate general valuation allowance. 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. Loans identified as losses by management, internal loan review and/or bank examiners are charged-off. Furthermore, consumer loan accounts are charged-off automatically based on regulatory requirements. The following table details activity in the allowance for loan losses by portfolio segment for the three and six months ended June 30, 2016 and 2015. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.

This reserve percentage, based on many factors including historical losses and existing economic conditions, is evaluated by management periodically and is applied to the total undisbursed loan commitment balance to calculate the reserve for off-balance-sheet commitments. Reserves for off-balance-sheet commitments are recorded in interest payable and other liabilities on the condensed consolidated balance sheets. At June 30, 2016 and December 31, 2015, loans carried at $579,774,000 and $541,032,000, respectively, were pledged as collateral on advances from the Federal Home Loan Bank.

Real Estate Owned [Text Block]	NOTE 6 – OTHER REAL ESTATE OWNED As of June 30, 2016, the Company owned three properties classified as other real estate totaling $1,231,000, compared to five properties totaling $2,066 ,000 as of December 31, 2015. Each of the OREO properties was acquired through loan foreclosure, except for one property with a balance of $275,000 that was acquired in the Mother Lode Bank acquisition. One of the properties owned at June 30, 2016 and December 31, 2015, was a residential land property that was written down to a zero balance because the public utilities have not been obtainable rendering these land lots unmarketable at this time. There was one sale during the six months ended June 30, 2016 that accounted for the disposition of two OREO properties, and there were no sales during the six months ended June 30, 2015. Real estate properties acquired through, or in lieu of, loan foreclosure are to be sold and are initially recorded at the lower of carrying amount of the loan or fair value of the property at the date of foreclosure less selling costs. Subsequent to foreclosure, valuations are periodically performed and any subject revisions in the estimate of fair value are reported as adjustment to the carrying value of the real estate, provided the adjusted carrying amount does not exceed the original amount at foreclosure. Revenues and expenses from operations and changes in the valuation allowance are included in other operating expenses.

Pension and Other Postretirement Benefits Disclosure [Text Block]	NOTE 7 – OTHER POST-RETIREMENT BENEFIT PLANS During January 2008, the Bank awarded certain officers a salary continuation plan (the “Plan”). Under the Plan, the participants will be provided with a fixed annual retirement benefit for ten to twenty years after retirement . The Bank is also responsible for certain pre-retirement death benefits under the Plan. In connection with the implementation of the Plan, the Bank purchased single premium life insurance policies on the life of each of the officers covered under the Plan. The Bank is the owner and partial beneficiary of these life insurance policies. The assets of the Plan, under Internal Revenue Service regulations, are owned by the Bank and are available to satisfy the Company’s general creditors. In August 2001, the Board of Directors of the Bank authorized Director Retirement Plans (“DRP”) with each director. The Bank awarded a director retirement plan to two of its directors in January 2008 and to three of its newest directors in March 2014. Under the DRP, the participants will be provided with a fixed annual retirement benefit for ten years after retirement. The Bank is also responsible for certain pre-retirement death benefits under the DRP. In connection with the implementation of the DRP, the Bank purchased single premium life insurance policies on the life of each director covered under the DRP. The Bank is the owner and partial beneficiary of these life insurance policies. The assets of the DRP, under Internal Revenue Service regulations, are the property of the Bank and are available to satisfy the Bank’s general creditors. Future compensation under both plans is earned for services rendered through retirement. The Bank accrues for the salary continuation liability based on anticipated years of service and vesting schedules provided under the plans. The Bank’s current benefit liability is determined based on vesting and the present value of the benefits at a corresponding discount rate. The discount rate used is an equivalent rate for investment-grade bonds with lives matching those of the service periods remaining for the salary continuation contracts, which average approximately 1 0 years. The salary continuation liability as of June 30, 2016 and December 31, 2015 was $2,463,000 and $2,440,000, respectively, and is reported in interest payable and other liabilities on the condensed consolidated balance sheets. During January 2008, the Bank purchased $4.7 million in bank owned life insurance policies and entered into split-dollar life insurance agreements with certain officers and directors. During March 2014, the Bank purchased an additional $1.0 million in bank owned life insurance policies and entered into split-dollar life insurance agreements with its three newest directors. In connection with the implementation of the split-dollar agreements, the Bank purchased single premium life insurance policies on the life of each of the officers and directors covered by the split-dollar life insurance agreements. The Bank is the owner of the policies and the partial beneficiary in an amount equal to the cash surrender value of the policies. The combined cash surrender value of all Bank-owned life insurance policies recorded in interest receivable and other assets on the condensed consolidated balance sheets were $13,766,000 and $13,747,000 at June 30, 2016 and December 31, 2015, respectively.

Fair Value, Measurement Inputs, Disclosure [Text Block]	NOTE 8 — FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS Fair values of financial instruments — Fair value measurements defines fair value, establishes a framework for measuring fair value, establishes a three-level valuation hierarchy for disclosure of fair value measurement and enhances disclosure requirements for fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follow: Level 1: Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2: Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstance that caused the transfer, which generally corresponds with the Company’s quarterly valuation process. There were no transfers between levels during the six month periods ended June 30, 2016 or 2015. Following is a description of valuation methodologies used for assets and liabilities in the tables below: Cash and cash equivalents – Restricted Equity Securities- Loans receivable Deposit liabilities Interest receivable and payable - Off-balance-sheet instruments .

Available-for-sale securities - Impaired loans Accounting by Creditors for Impairment of a Loan Other Real Estate Owned Net realizable value of the underlying collateral is the fair value of the collateral less estimated selling costs and any prior liens. Appraisals, recent comparable sales, offers and listing prices are factored in when valuing the collateral. We review and verify the qualifications and licenses of the certified general appraisers used for appraising commercial properties or certified residential appraisers for residential properties. Real estate appraisals may utilize a combination of approaches including replacement cost, sales comparison and the income approach. Comparable sales and income data are analyzed by the appraisers and adjusted to reflect differences between them and the subject property such as type, leasing status and physical condition. When the appraisals are received, Management reviews the assumptions and methodology utilized in the appraisal, as well as the overall resulting value in conjunction with independent data sources such as recent market data and industry-wide statistics. We generally use a 6% discount for selling costs which is applied to all properties, regardless of size. Appraised values may be adjusted to reflect changes in market conditions that have occurred subsequent to the appraisal date, or for revised estimates regarding the timing or cost of the property sale. These adjustments are based on qualitative judgments made by management on a case-by-case basis. No fair value adjustments were made to OREO properties during the three and six months ended June 30, 2016. There have been no significant changes in the valuation techniques during the period ended June 30, 2016.

Earnings Per Share [Text Block]	NOTE 9 – EARNINGS PER SHARE Earnings per share (“EPS”) are based upon the weighted average number of common shares outstanding during each year. The following table shows: (1) weighted average basic shares, (2) effect of dilutive securities related to stock options and non-vested restricted stock, and (3) weighted average shares of common stock and common stock equivalents. Net income available to common stockholders is calculated as net income reduced by dividends accumulated on preferred stock, if any. Basic EPS are calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding during each period, excluding unvested restricted stock awards. Diluted EPS are calculated using the weighted average diluted shares, which reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. The dilutive shares included in year-to-date diluted EPS is a weighted average of the dilutive shares included in each quarterly diluted EPS computation under the treasury stock method. We have two forms of outstanding common stock: common stock and unvested restricted stock awards. Holders of restricted stock awards receive non-forfeitable dividends at the same rate as common stockholders and they both share equally in undistributed earnings. Therefore, under the two class method the difference in EPS is not significant for these participating securities. The Company’s calculation of basic and diluted earnings per share (“EPS”) for the three and six month periods ended June 30, 2016 and 2015 are reflected in the table below.

Anti-dilutive weighted average stock options of 51,843 and 56,919 were outstanding during the three and six month periods of 2015, respectively, with prices ranging from $9.95 to $15.67. These options were not included in the computation of diluted EPS because the options’ exercise price was greater than the average market price of the common shares. These options begin to expire in 2016 . There were no anti-dilutive non-vested restricted stock grants for the three and six months ended June 30, 2016 and 2015.
