Accounting Policies [Abstract]	'
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
		2	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	General
	The accounting and reporting policies of the Company and its subsidiaries conform with accounting principles generally accepted in the United States of America and prevailing practices within the financial services industry.
	Reclassifications
	Certain reclassifications have been made to prior years’ balances to conform to classifications used in 2013. Reclassifications had no affect on prior year net income or shareholders’ equity.
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany transactions and accounts have been eliminated in consolidation.
	Use of Estimates
	The preparation of 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. The allowance for loan and lease losses and fair values of financial instruments are particularly subject to change.
	Cash and Cash Equivalents
	For the purpose of the statement of cash flows, cash and due from banks and Federal funds sold are considered to be cash equivalents. Generally, Federal funds are sold for one-day periods.
	Interest-Bearing Deposits in Banks
	Interest-bearing deposits in banks mature within one year and are carried at cost.
	Investment Securities
	Investments are classified into the following categories:
		●	Available-for-sale securities, reported at fair value, with unrealized gains and losses excluded from earnings and reported, net of taxes, as accumulated other comprehensive income (loss) within shareholders’ equity.
		●	Held-to-maturity securities, which management has the positive intent and ability to hold to maturity, reported at amortized cost, adjusted for the accretion of discounts and amortization of premiums.
	Management determines the appropriate classification of its investments at the time of purchase and may only change the classification in certain limited circumstances. All transfers between categories are accounted for at fair value. There were no transfers during the years ended December 31, 2013 and 2012.
	Gains or losses on the sale of investment securities are computed on the specific identification method. Interest earned on investment securities is reported in interest income, net of applicable adjustments for accretion of discounts and amortization of premiums.
	An investment security is impaired when its carrying value is greater than its fair value. Investment securities that are impaired are evaluated on at least a quarterly basis and more frequently when economic or market conditions warrant such an evaluation to determine whether a decline in their value is other than temporary. Management utilizes criteria such as the magnitude and duration of the decline and the intent and ability of the Company to retain its investment in the securities for a period of time sufficient to allow for an anticipated recovery in fair value, in addition to the reasons underlying the decline, to determine whether the loss in value is other than temporary. The term “other than temporary” is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value is not necessarily favorable, or that there is a lack of evidence to support a realizable value equal to or greater than the carrying value of the investment. For debt securities, once a decline in value is determined to be other than temporary and management does not intend to sell the security or it is more likely than not that management will not be required to sell the security before recovery, only the portion of the impairment loss representing credit exposure is recognized as a charge to earnings, with the balance recognized as a charge to other comprehensive income. If management intends to sell the security or it is more likely than not that management will be required to sell the security before recovering its forecasted cost, the entire impairment loss is recognized as a charge to earnings. For equity securities, the entire amount of impairment is recognized through earnings.
	Federal Home Loan Bank Stock
	Investments in Federal Home Loan Bank of San Francisco (the “FHLB”) stock are carried at cost and are redeemable at par with certain restrictions. Investments in FHLB stock are necessary to participate in FHLB programs.
	Loans and Leases
	Loans and leases that management has both the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal amounts outstanding, adjusted for unearned income, deferred loan origination fees and costs, purchase premiums and discounts, write-downs and the allowance for loan and lease losses. Loan and lease origination fees, net of certain deferred origination costs, and purchase premiums and discounts are recognized as an adjustment to the yield of the related loans and leases.
	For all classes of loans and leases, the accrual of interest is discontinued when, in the opinion of management, there is an indication that the borrower may be unable to meet payment requirements within an acceptable time frame relative to the terms stated in the loan agreement. Upon such discontinuance, all unpaid accrued interest is reversed against current income unless the loan or lease is well secured and in the process of collection. Interest received on nonaccrual loans and leases is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Generally, loans and leases are restored to accrual status when the obligation is brought current and has performed in accordance with the contractual terms for a reasonable period of time and the ultimate collectability of the total contractual principal and interest is no longer in doubt.
	Direct financing leases are carried net of unearned income. Income from leases is recognized by a method that approximates a level yield on the outstanding net investment in the lease.
	Loan Sales and Servicing
	Included in the loan and lease portfolio are Small Business Administration (“SBA”) loans and Farm Service Agency guaranteed loans that may be sold in the secondary market. At the time the loan is sold, the related right to service the loan is either retained, with the Company earning future servicing income, or released in exchange for a one-time servicing-released premium. Loans subsequently transferred to the loan portfolio are transferred at the lower of cost or fair value at the date of transfer. Any difference between the carrying amount of the loan and its outstanding principal balance is recognized as an adjustment to yield by the interest method. There were no loans held for sale at December 31, 2013 and 2012.
	SBA and Farm Service Agency loans with unpaid balances of $269,000 and $328,000 were being serviced for others as of December 31, 2013 and 2012, respectively. The Company also serviced loans that are participated with other financial institutions totaling $8,320,000 and $10,108,000 as of December 31, 2013 and 2012, respectively.
	Servicing rights acquired through 1) a purchase or 2) the origination of loans which are sold or securitized with servicing rights retained are recognized as separate assets or liabilities. Servicing assets or liabilities are initially recorded at fair value and are subsequently amortized in proportion to and over the period of the related net servicing income or expense. Servicing assets are periodically evaluated for impairment. Servicing assets were not considered material for disclosure purposes at December 31, 2013 and 2012.
	Allowance for Loan and Lease Losses
	The allowance for loan and lease losses is an estimate of probable credit losses inherent in the Company’s credit portfolio that have been incurred as of the balance-sheet date. The allowance is established through a provision for loan and lease losses which is charged to expense. Additions to the allowance are expected to maintain the adequacy of the total allowance after credit losses and loan growth. Credit exposures determined to be uncollectible are charged against the allowance. Cash received on previously charged off amounts is typically recorded as a recovery to the allowance. The overall allowance consists of two primary components, specific reserves related to impaired credits and general reserves for inherent probable losses related to credits that are not impaired.
	For all classes of the portfolio, a loan or lease is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the original agreement. Impaired loans are individually evaluated to determine the extent of impairment, if any, except for smaller-balance loans that are collectively evaluated for credit risk. When a loan or lease is impaired, the Company measures impairment based on the present value of expected future cash flows discounted at the credit’s original interest rate, except that as a practical expedient, it may measure impairment based on a credit’s observable market price, or the fair value of the collateral if the credit is collateral dependent. A loan or lease is collateral dependent if the repayment of the credit is expected to be provided solely by the sale or operation of the underlying collateral.
	For all portfolio segments, a restructuring of a debt constitutes a troubled debt restructuring (“TDR”) if the Company grants a concession to the borrower for economic or legal reasons related to the borrower’s financial difficulties that it would not otherwise consider. Restructured workout loans typically present an elevated level of credit risk as the borrowers are not able to perform according to the original contractual terms. Loans or leases that are reported as TDRs are considered impaired and measured for impairment as described above.
	For all portfolio segments, the determination of the general reserve for loans and leases that are not impaired is based on estimates made by management, to include, but not limited to, consideration of historical losses by portfolio segment, internal asset classifications, and qualitative factors to include economic trends in the Company’s service areas, industry experience and trends, geographic concentrations, estimated collateral values, the Company’s underwriting policies, the character of the credit portfolio, and probable losses inherent in the portfolio taken as a whole.
	The Company determines a separate allowance for each portfolio segment. These portfolio segments include commercial, real estate construction (including land and development loans), residential real estate, multi-family real estate, commercial real estate, leases, agriculture and consumer loans. The allowance for loan and lease losses attributable to each portfolio segment, which includes both impaired credits and credits that are not impaired, is combined to determine the Company’s overall allowance, which is included as a component of loans and leases on the consolidated balance sheet and available for all loss exposures.
	The Company assigns a risk rating to all loans and periodically performs detailed reviews of all such loans over a certain threshold to identify credit risks and to assess the overall collectability of the portfolio. These risk ratings are also subject to examination by independent specialists engaged by the Company and the Company’s regulators. During the internal reviews, management monitors and analyzes the financial condition of borrowers and guarantors, trends in the industries in which borrowers operate and the fair values of collateral securing these loans. These credit quality indicators are used to assign a risk rating to each individual credit. The risk ratings can be grouped into six major categories, defined as follows:
	Pass – A pass loan is a strong credit with no existing or known potential weaknesses deserving of management’s close attention.
	Watch – A watch credit is a loan or lease that otherwise meets the definition of a standard or minimum acceptable quality loan, but which requires more than normal attention due to any of the following items: deterioration of borrower financial condition less severe than those warranting more adverse grading, deterioration of repayment ability and/or collateral value, increased leverage, adverse effects from a downturn in the economy, local market or industry, adverse changes in local or regional employer, management changes (including illness, disability, and death), and adverse legal action. Payments are current per the terms of the agreement. If conditions persist or worsen, a more severe risk grade may be warranted.
	Special Mention – A special mention credit is a loan or lease that has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the credit or in the Company’s position at some future date. Special Mention credits are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.
	Substandard – A substandard credit is a loan or lease that is not adequately protected by the current sound worth and paying capacity of the borrower or the value of the collateral pledged, if any. Credits classified as substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Well defined weaknesses include inadequate cash flow or collateral support, a project’s lack of marketability, failure to complete construction on time or a project’s failure to fulfill economic expectations. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
	Doubtful – Credits classified as doubtful are loans or leases that have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions and values, highly questionable and improbable.
	Loss – Credits classified as loss are loans or leases considered uncollectible and charged off immediately.
	The general reserve component of the allowance for loan and lease losses also consists of reserve factors that are based on management’s assessment of the following for each portfolio segment: (1) inherent credit risk, (2) historical losses and (3) other qualitative factors. These reserve factors are inherently subjective and are driven by the repayment risk associated with each portfolio segment described below.
	Real Estate- Commercial – Commercial real estate mortgage loans generally possess a higher inherent risk of loss than other real estate portfolio segments, except land and construction loans. Adverse economic developments or an overbuilt market impact commercial real estate projects and may result in troubled loans. Trends in vacancy rates of commercial properties impact the credit quality of these loans. High vacancy rates reduce operating revenues and the ability for properties to produce sufficient cash flow to service debt obligations.
	Real Estate- Construction – These loans generally possess a higher inherent risk of loss than other real estate portfolio segments. A major risk arises from the necessity to complete projects within specified cost and time lines. Trends in the construction industry significantly impact the credit quality of these loans, as demand drives construction activity. In addition, trends in real estate values significantly impact the credit quality of these loans, as property values determine the economic viability of construction projects.
	Real Estate- Multi-family – Multi-family loans are non-construction term mortgages for the acquisition, refinance, or improvement of residential rental properties with generally more than 4 dwelling units. Underwriting is generally based on borrower creditworthiness, sufficiency of net operating income to service the bank loan payment, and a prudent loan-to-value ratio, among other factors.
	Real Estate- Residential – Residential loans are generally loans to purchase or refinance 1-4 unit single-family residences, either owner-occupied or investor-owned. Some residential loans are short term to match their intended source of repayment through sale or refinance. The remainder are fixed or floating-rate term first mortgages with an original maturity between 2 and 10 years, generally with payments based on a 25-30 year amortization.
	Commercial – Commercial loans generally possess a lower inherent risk of loss than real estate portfolio segments because these loans are generally underwritten to existing cash flows of operating businesses. Debt coverage is provided by business cash flows and economic trends influenced by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans.
	Lease Financing Receivable – Leases originated by the bank are non-consumer finance leases (as contrasted with operating leases) for the acquisition of titled and non-titled business equipment. Leases are generally amortized over a period from 36 to 84 months, depending on the useful life of the equipment acquired. Residual (balloon) payments at lease end range from 0-20% of original cost, and are a non-optional obligation of the lessee. Lessees are contractually responsible for all costs, expenses, taxes, and liability associated with the leased equipment.
	Agricultural – Loans secured by crop production and livestock are especially vulnerable to two risk factors that are largely outside the control of the Company and borrowers: commodity prices and weather conditions.
	Consumer – The consumer loan portfolio is comprised of a large number of small loans scheduled to be amortized over a specific period. Most installment loans are made directly for consumer purchases, but business loans granted for the purchase of heavy equipment or industrial vehicles may also be included. Also included in the consumer loan portfolio are home equity lines of credit. Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate that the borrowers’ capacity to repay their obligations may be deteriorating.
	Although management believes the allowance to be adequate, ultimate losses may vary from its estimates. At least quarterly, the Board of Directors reviews the adequacy of the allowance, including consideration of the relative risks in the portfolio, current economic conditions and other factors. If the Board of Directors and management determine that changes are warranted based on those reviews, the allowance is adjusted. In addition, the Company’s primary regulators, the FDIC and the California Department of Business Oversight, as an integral part of their examination process, review the adequacy of the allowance. These regulatory agencies may require additions to the allowance based on their judgment about information available at the time of their examinations.
	Allowance for Credit Losses on Off-Balance-Sheet Credit Exposures
	The Company also maintains a separate allowance for off-balance-sheet commitments. Management estimates probable incurred losses using historical data and utilization assumptions. The allowance for off-balance-sheet commitments is included in accrued interest payable and other liabilities on the consolidated balance sheet.
	Other Real Estate Owned (OREO)
	Other real estate owned includes real estate acquired in full or partial settlement of loan obligations. When property is acquired, any excess of the recorded investment in the loan balance and accrued interest income over the estimated fair market value of the property less estimated selling costs is charged against the allowance for loan and lease losses. A valuation allowance for losses on other real estate may be maintained to provide for temporary declines in value. The valuation allowance is established through a provision for losses on other real estate which is included in other expenses. Subsequent gains or losses on sales or writedowns resulting from permanent impairments are recorded in other income or expense as incurred. During 2013, the Company received $7,475,000 in net proceeds from the sale of other real estate owned with net gains of $44,000 recognized on the sale. During 2012, the Company received $3,637,000 in net proceeds from the sale of other real estate owned with net losses of $2,000 recognized on the sale. The recorded investment in other real estate owned totaled $6,621,000 and $12,237,000 at December 31, 2013 and 2012, respectively, and had related valuation allowances of $106,000 and $175,000, respectively.
	Premises and Equipment
	Premises and equipment are carried at cost. Depreciation is determined using the straight-line method over the estimated useful lives of the related assets. The useful life of the building and improvements is forty years. The useful lives of furniture, fixtures and equipment are estimated to be three to ten years. Leasehold improvements are amortized over the life of the asset or the term of the related lease, whichever is shorter. When assets are sold or otherwise disposed of, the cost and related accumulated depreciation or amortization are removed from the accounts, and any resulting gain or loss is recognized in income for the period. The cost of maintenance and repairs is charged to expense as incurred. Impairment of long-lived assets is evaluated by management based upon an event or changes in circumstances surrounding the underlying assets which indicate long-lived assets may be impaired.
	Goodwill and Intangible Assets
	Business combinations involving the Company’s acquisition of equity interests or net assets of another enterprise or the assumption of net liabilities in an acquisition of branches constituting a business may give rise to goodwill. Goodwill represents the excess of the cost of an acquired entity over the net of the amounts assigned to assets acquired and liabilities assumed. The value of goodwill is ultimately derived from the Company’s ability to generate net earnings after the acquisition and is not deductible for tax purposes. A decline in net earnings could be indicative of a decline in the fair value of goodwill and result in impairment. For that reason, goodwill is assessed for impairment at least annually. Impairment exists when a reporting unit’s carrying value of goodwill exceeds its fair value. At December 31, 2013, the Company had one reporting unit and that reporting unit had positive equity and the Company elected to perform a qualitative assessment to determine if it was more likely than not that the fair value of the reporting unit exceeded its carrying value, including goodwill. The qualitative assessment indicated that it was more likely than not that the fair value of the reporting unit exceeded its carrying value, resulting in no impairment.
	Intangible assets are comprised of core deposit intangibles which represent the estimated fair value of the long-term deposit relationships that were assumed when the Company acquired Bank of Amador in December 2004. Core deposit intangibles are amortized over a period that approximates the expected run-off of the deposit base, which, in this case, is eight years. The intangible asset related to the Bank of Amador acquisition became fully amortized during 2012.
	Bank-Owned Life Insurance
The Company has purchased life insurance policies on certain key executives. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Income Taxes
The Company files its income taxes on a consolidated basis with its subsidiaries. The allocation of income tax expense represents each entity’s proportionate share of the consolidated provision for income taxes.
The Company accounts for income taxes using the balance sheet method, under which deferred tax assets and liabilities are recognized for the tax consequences of temporary differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. The deferred provision for income taxes is the result of the net change in the deferred tax asset and deferred tax liability balances during the year. This amount combined with the current taxes payable or refundable, results in the income tax expense for the current year. On the consolidated balance sheet, net deferred tax assets are included in accrued interest receivable and other assets.
The realization of deferred income tax assets is assessed and a valuation allowance is recorded if it is “more likely than not” that all or a portion of the deferred tax assets will not be realized. “More likely than not” is defined as greater than a 50% chance. All available evidence, both positive and negative is considered to determine whether, based on the weight of that evidence, a valuation allowance is needed. Based upon the Company’s analysis of available evidence, the Company determined that it is “more likely than not” that all of the deferred income tax assets as of December 31, 2013 and 2012 will be fully realized and therefore no valuation allowance was recorded.
The Company uses a comprehensive model for recognizing, measuring, presenting and disclosing in the financial statements tax positions taken or expected to be taken on a tax return. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Interest expense and penalties associated with unrecognized tax benefits, if any, are classified as income tax expense in the consolidated statement of income.
Comprehensive Income
Comprehensive income is reported in addition to net income for all periods presented. Comprehensive income is a more inclusive financial reporting methodology that includes disclosure of other comprehensive income (loss) that historically has not been recognized in the calculation of net income. Unrealized gains and losses on the Company’s available-for-sale investment securities are included in other comprehensive income (loss), adjusted for realized gains or losses included in net income. Total comprehensive income and the components of accumulated other comprehensive income (loss) are presented in the consolidated statements of comprehensive income.
Earnings Per Share
Basic earnings per share (“EPS”), which excludes dilution, is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock, such as stock options or restricted stock, result in the issuance of common stock that share in the earnings of the Company. The treasury stock method has been applied to determine the dilutive effect of stock options and restricted stock in computing diluted EPS. Earnings and dividends per share are restated for all stock splits and stock dividends through the date of issuance of the consolidated financial statements. There were no stock splits or stock dividends in 2013, 2012 or 2011.
Stock-Based Compensation
At December 31, 2013, the Company had two stock-based compensation plans, which are described more fully in Note 13. Compensation expense, net of related tax benefits, recorded in 2013, 2012 and 2011 totaled $84,000, $102,000 and $180,000, or $0.01, $0.01 and $0.02 per diluted share, respectively. Compensation expense is recognized over the vesting period on a straight line accounting basis.
The fair value of each option award is estimated on the date of grant using a Black-Scholes-Merton based option valuation model that uses the assumptions noted in the following table. Because Black-Scholes-Merton based option valuation models incorporate ranges of assumptions for inputs, those ranges are disclosed. Expected volatilities are based on historical volatility of the Company’s stock and other factors. The Company uses historical data to estimate the dividend yield, option life and forfeiture rate within the valuation model. The expected option life represents the period of time that options granted are expected to be outstanding. The risk-free rate for the period representing the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.
		2012
Dividend yield			0	%
Expected volatility			28.8	%
Risk-free interest rate			1.19	%
Expected option life in years			7
Weighted average fair value of options granted during the year		$	2.31
There were no options granted in 2013 or 2011 under either stock-based compensation plans.
Restricted stock awards are grants of shares of the Company’s common stock that are subject to forfeiture until specific conditions or goals are met. Conditions may be based on continuing employment or service and/or achieving specified performance goals. During the period of restriction, Plan participants holding restricted share awards have voting and cash dividend rights. The restrictions lapse in accordance with a schedule or with other conditions determined by the Board of Directors as reflected in each award agreement. Upon the vesting of each restricted stock award, the Company issues the associated common shares from its inventory of authorized common shares. All outstanding awards under the Plan immediately vest in the event of a change of control of the Company. The shares associated with any awards that fail to vest become available for re-issuance under the Plan.
The following is a summary of stock-based compensation information as of or for the years ended December 31, 2013, 2012 and 2011:

Operating Segments
While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
Adoption of New Accounting Standards
In February 2013, the Financial Accounting Standards Board amended existing guidance related to reporting amounts reclassified out of other comprehensive income out of accumulated other comprehensive income.  These amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. These amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. Generally Accepted Accounting Principles (“GAAP”) to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional details about those amounts. These amendments are effective prospectively for interim and annual reporting periods beginning after December 15, 2012. The effect of adopting this standard did not have a material effect on the Company’s consolidated financial position, results of operations or cash flows.

FAIR VALUE MEASUREMENTS	'
		3	FAIR VALUE MEASUREMENTS
	The following tables present information about the Company’s assets and liabilities measured at fair value on a recurring and nonrecurring basis as of December 31, 2013 and December 31, 2012. They indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. 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.
	Estimated fair values are disclosed for financial instruments for which it is practicable to estimate fair value. These estimates are made at a specific point in time based on relevant market data and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates.
	The carrying amounts and estimated fair values of the Company’s financial instruments are as follows (dollars in thousands):

	Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the fair values presented.
	The following methods and assumptions were used by the Company to estimate the fair values of its financial instruments at December 31, 2013 and December 31, 2012:
	Cash and due from banks: The carrying amounts of cash and short-term instruments approximate fair values and are classified as Level 1.
	Interest-bearing deposits in banks: The fair values of interest-bearing deposits in banks are estimated by discounting their future cash flows using rates at each reporting date for instruments with similar remaining maturities offered by comparable financial institutions and are classified as Level 2.
	Investment securities: For investment securities, fair values are based on quoted market prices, where available, and are classified as Level 1. If quoted market prices are not available, fair values are estimated using quoted market prices for similar securities and indications of value provided by brokers and are classified as Level 2.
	FHLB stock: It is not practicable to determine the fair value of FHLB stock due to restrictions placed on its transferability.
	Loans and leases: Fair values of loans, excluding loans held for sale, are estimated as follows:  For variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values resulting in a Level 3 classification. Fair values for other loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality also resulting in a Level 3 classification. Impaired loans are valued at the lower of cost or fair value. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price.
	Deposits: The fair values disclosed for demand deposits (e.g. interest and non-interest checking, passbook savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e. their carrying amount) resulting in a Level 1 classification. For time deposits, the fair values for fixed rate certificates of deposit are estimated using a discounted cash flow methodology that applies market interest rates to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification.
	Short-term and long-term borrowings: The fair value of short-term borrowings is estimated to be the carrying amount and is classified as Level 1. The fair value of long-term borrowings is estimated using a discounted cash flow analysis using interest rates currently available for similar debt instruments and are classified as Level 2.
	Accrued interest receivable and payable: The carrying amount of accrued interest receivable and accrued interest payable approximates fair value resulting in a Level 2 or 3 classification consistent with the asset or liability it is associated with..
	Off-balance sheet instruments: Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The fair value of commitments was not material at December 31, 2013 and December 31, 2012.
	Assets and liabilities measured at fair value on a recurring and non-recurring basis are presented in the following table:

There were no transfers between Levels 1 and 2 during the years ended December 31, 2013 or December 31, 2012.
The following methods were used to estimate the fair value of each class of financial instrument above:
Available-for-sale securities – Fair values for investment securities are based on quoted market prices, if available, and are considered Level 1, or evaluated using pricing models that vary by asset class and incorporate available trade, bid and other market information and are considered Level 2. Pricing applications apply available information, as applicable, through processes such as benchmark curves, benchmarking to like securities, sector groupings and matrix pricing.
Impaired loans – The fair value of collateral dependent impaired loans adjusted for specific allocations of the allowance for loan losses is generally based on recent real estate appraisals and/or evaluations. These appraisals and/or evaluations may utilize a single valuation approach or a combination of approaches including comparable sales, cost and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income and other available data. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. The valuation technique used for all Level 3 nonrecurring impaired loans is the sales comparison approach less a reserve for past dues taxes and selling costs ranging from 8% to 10%.
Other real estate owned – Certain commercial and residential real estate properties classified as OREO are measured at fair value, less costs to sell. Fair values are based on recent real estate appraisals and/or evaluations. These appraisals and/or evaluations may use a single valuation approach or a combination of approaches including comparable sales, cost and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income and other available data. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. The valuation technique used for all Level 3 nonrecurring OREO is the sales comparison approach less selling costs ranging from 8% to 10%.

At December 31, 2013, the Company held 216 securities of which 49 were in a loss position for less than twelve months and five were in a loss position for twelve months or more. Of these securities 44 are mortgage-backed securities and five are obligations of states and political subdivisions.
The unrealized loss on the Company’s investments in mortgage-backed securities is primarily driven by interest rates. Because the decline in market value is attributable to a change in interest rates and not credit quality, and because the Company has the ability and intent to hold these investments until recovery of fair value, which may be maturity, management does not consider these investments to be other-than-temporarily impaired.

Troubled Debt Restructurings
At December 31, 2013 and 2012, the Company had $13,207,000 and $17,367,000 in loans to clients whose loan terms were modified in troubled debt restructurings, respectively. The Company had allocated $817,000 and $1,575,000 of specific reserves to these troubled debt restructurings as of December 31, 2013 and 2012, respectively. The Company has not committed to lend additional amounts as of December 31, 2013 and 2012 to borrowers with outstanding loans that are classified as troubled debt restructurings.
During the period ended December 31, 2013, the terms of certain loans were modified as troubled debt restructurings. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan at a stated rate of interest lower than the current market rate for new debt with similar risk; an extension of the maturity date; or a term out of a revolving loan.
Modifications involving a reduction of the stated interest rate of the loan were for periods ranging from one month to eight years. Modifications involving an extension of the maturity date were for periods ranging from six months to eight years.

	Financial Instruments With Off-Balance-Sheet Risk
	The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business in order to meet the financing needs of its customers and to reduce its exposure to fluctuations in interest rates. These financial instruments consist of commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized on the consolidated balance sheet.
	The Company’s exposure to credit loss in the event of nonperformance by the other party for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and standby letters of credit as it does for loans included on the consolidated balance sheet.
	The following financial instruments represent off-balance-sheet credit risk (dollars in thousands):
			December 31,
			2013				2012
	Commitments to extend credit:
	Revolving lines of credit secured by 1-4 family residences		$	2,071			$	3,644
	Commercial real estate, construction and land development commitments secured by real estate			11,890				7,587
	Other unused commitments, principally commercial loans			17,720				15,287
			$	31,681			$	26,518
	Standby letters of credit		$	6,363			$	6,506
	At inception, real estate commitments are generally secured by property with a loan to value ratio of 55% to 75%. In addition, the majority of the Company’s commitments have variable interest rates.
	Commitments to extend credit are agreements to lend to a client as long as there is no violation of any conditions established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Each client’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies but may include accounts receivable, inventory, equipment and deeds of trust on residential real estate and income-producing commercial properties.
	Standby letters of credit are conditional commitments issued to guarantee the performance or financial obligation of a client to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to clients.
	Significant Concentrations of Credit Risk
	The Company grants real estate mortgage, real estate construction, commercial, agricultural and consumer loans to clients throughout Sacramento, Placer, Yolo, Amador, El Dorado, and Sonoma counties.
	In management’s judgment, a concentration exists in real estate-related loans which represented approximately 86% and 83% of the Company’s loan portfolio at December 31, 2013 and 2012, respectively. A continued substantial decline in the economy in general, or a continued decline in real estate values in the Company’s primary market areas in particular, could have an adverse impact on collectability of these loans. However, personal and business income represents the primary source of repayment for a majority of these loans.
	Correspondent Banking Agreements
	The Company maintains funds on deposit with other federally insured financial institutions under correspondent banking agreements. The Company had $2,768,000 in uninsured deposits at December 31, 2013. There were no uninsured deposits at December 31, 2012.
	Contingencies
	The Company is subject to legal proceedings and claims which arise in the ordinary course of business. In the opinion of management, the amount of ultimate liability with respect to such actions will not materially affect the consolidated financial position or results of operations of the Company.

	Stock Based Compensation
	In 2000, the Board of Directors adopted and the Company’s shareholders approved a stock option plan (the “2000 Plan”), under which 260,594 options remain outstanding at December 31, 2013. On March 17, 2010, the Board of Directors adopted the 2010 Equity Incentive Plan (the “2010 Plan”). The 2010 Plan was approved by the Company’s shareholders on May 20, 2010. The total number of authorized shares that are available for issuance under the 2010 Plan is 1,432,312. The 2010 Plan provides for the following types of stock-based awards: incentive stock options; nonqualified stock options; stock appreciation rights; restricted stock; restricted performance stock; unrestricted Company stock; and performance units. Awards granted under the 2000 Plan were either incentive stock options or nonqualified stock options. The 2010 Plan and the 2000 Plan (collectively the “Plans”), under which equity incentives may be granted to employees and directors under incentive and nonstatutory agreements, require that the option price may not be less than the fair value of the stock at the date the option is granted. The option awards under the Plans expire on dates determined by the Board of Directors, but not later than ten years from the date of award. The vesting period is generally five years; however, the vesting period can be modified at the discretion of the Company’s Board of Directors. Outstanding option awards under the Plans are exercisable until their expiration; however, no new options will be awarded under the 2000 Plan. The Plans do not provide for the settlement of awards in cash and new shares are issued upon exercise of an option.

Regulatory Capital Requirements [Abstract]	'
REGULATORY MATTERS	'
		14	REGULATORY MATTERS
	Dividends
	Upon declaration by the Board of Directors of the Company, all shareholders of record will be entitled to receive dividends. There is no assurance, however, that any dividends will be paid in the future since they are subject to regulatory restrictions, and dependent upon earnings, financial condition and capital requirements of the Company and its subsidiaries. On July 24, 2009, the Board of Directors temporarily suspended the payment of cash dividends until such time as it is prudent to reestablish payment of cash dividends. As a result there were no cash dividends declared or paid in 2011, 2012 or 2013.
	As a California corporation, the Company’s ability to pay cash dividends is subject to restrictions set forth in the California General Corporation Law (the “Corporation Law”). The Corporation Law provides that neither a corporation nor any of its subsidiaries shall make a distribution to the corporation’s shareholders unless the board of directors has determined in good faith either of the following: (1) the amount of retained earnings of the corporation immediately prior to the distribution equals or exceeds the sum of (A) the amount of the proposed distribution plus (B) the preferential dividends arrears amount; or (2) immediately after the distribution, the value of the corporation’s assets would equal or exceed the sum of its total liabilities plus the preferential rights amount. The good faith determination of the board of directors may be based upon (1) financial statements prepared on the basis of reasonable accounting practices and principles, (2) a fair valuation, or (3) any other method reasonable under the circumstances; provided, that a distribution may not be made if the corporation or subsidiary making the distribution is, or is likely to be, unable to meet its liabilities (except those whose payment is otherwise adequately provided for) as they mature. The term “preferential dividends arrears amount” means the amount, if any, of cumulative dividends in arrears on all shares having a preference with respect to payment of dividends over the class or series to which the applicable distribution is being made, provided that if the articles of incorporation provide that a distribution can be made without regard to preferential dividends arrears amount, then the preferential dividends arrears amount shall be zero. The term “preferential rights amount” means the amount that would be needed if the corporation were to be dissolved at the time of the distribution to satisfy the preferential rights, including accrued but unpaid dividends, of other shareholders upon dissolution that are superior to the rights of the shareholders receiving the distribution, provided that if the articles of incorporation provide that a distribution can be made without regard to any preferential rights, then the preferential rights amount shall be zero.
	In addition, the California Financial Code restricts the total dividend payment of any state banking corporation in any calendar year to the lesser of (1) the bank’s retained earnings or (2) the bank’s net income for its last three fiscal years, less distributions made to shareholders during the same three-year period. In addition, subject to prior regulatory approval, any state banking corporation may request an exception to this restriction.
	Regulatory Capital
	The Company and ARB are subject to certain regulatory capital requirements administered by the Board of Governors of the Federal Reserve System and the FDIC. Failure to meet these 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 consolidated financial statements.
	Under capital adequacy guidelines, the Company and ARB must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. These quantitative measures are established by regulation and require that minimum amounts and ratios of total and Tier 1 capital to risk-weighted assets and of Tier 1 capital to average assets be maintained. Capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.
	To be categorized as well capitalized, ARB must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table below.
	Management believes that the Company and ARB met all their capital adequacy requirements as of December 31, 2013 and 2012.

EMPLOYEE BENEFIT PLANS	'
		16	EMPLOYEE BENEFIT PLANS
	American River Bankshares 401(k) Plan
	The American River Bankshares 401(k) Plan has been in place since January 1, 1993 and is available to all employees. Under the plan, the Company will match 100% of each participant’s contribution up to 3% of annual compensation plus 50% of the next 2% of annual compensation. Employer Safe Harbor matching contributions are 100% vested upon entering the plan. The Company’s contributions totaled $181,000, $184,000 and $172,000 for the years ended December 31, 2013, 2012 and 2011, respectively.
	Employee Stock Purchase Plan
	The Company contracts with an administrator for an Employee Stock Purchase Plan which allows employees to purchase the Company’s stock at fair market value as of the date of purchase. The Company bears all costs of administering the Plan, including broker’s fees, commissions, postage and other costs actually incurred.
	American River Bankshares Deferred Compensation Plan
	The Company has established a Deferred Compensation Plan for certain members of the management team and a Deferred Fee Agreement for Non-Employee Directors for the purpose of providing the opportunity for participants to defer compensation. Participants of the management team, who are selected by a committee designated by the Board of Directors, may elect to defer annually a minimum of $5,000 or a maximum of eighty percent of their base salary and all of their cash bonus. Directors may also elect to defer up to one hundred percent of their monthly fees. The Company bears all administration costs and accrues interest on the participants’ deferred balances at a rate based on U.S. Government Treasury rates plus 4.0%. This rate was 4.72% at December 31, 2013. Deferred compensation, including interest earned, totaled $2,543,000 and $2,436,000 at December 31, 2013 and 2012, respectively. The expense recognized under this plan totaled $117,000, $116,000 and $138,000 for the years ended December 31, 2013, 2012 and 2011, respectively.
	Salary Continuation Plan
	The Company has agreements to provide certain current executives, or their designated beneficiaries, with annual benefits for up to 15 years after retirement or death. These benefits are substantially equivalent to those available under life insurance policies purchased by the Company on the lives of the executives. The Company accrues for these future benefits from the effective date of the agreements until the executives’ expected final payment dates in a systematic and rational manner. As of December 31, 2013 and 2012, the Company had accrued $1,132,000 and $1,054,000, respectively, for potential benefits payable. This payable approximates the then present value of the benefits expected to be provided at retirement and is included in accrued interest payable and other liabilities on the consolidated balance sheet. The expense recognized under this plan totaled $170,000, $143,000 and $166,000 for the years ended December 31, 2013, 2012 and 2011, respectively.
	In connection with these plans, the Company invested in single premium life insurance policies with cash surrender values totaling $12,686,000 and $12,858,000 at December 31, 2013 and 2012, respectively. On the consolidated balance sheet, the cash surrender value of life insurance policies is included in accrued interest receivable and other assets. Tax-exempt income on these policies, net of expense, totaled approximately $365,000, $267,000 and $272,000 for the years ended December 31, 2013, 2012 and 2011, respectively. In 2013, $118,000 of this tax-exempt income was from the death benefit proceeds of a life insurance policy on a former director.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
General	'
	General
	The accounting and reporting policies of the Company and its subsidiaries conform with accounting principles generally accepted in the United States of America and prevailing practices within the financial services industry.
Reclassifications	'
	Reclassifications
	Certain reclassifications have been made to prior years’ balances to conform to classifications used in 2013. Reclassifications had no affect on prior year net income or shareholders’ equity.
Principles of Consolidation	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany transactions and accounts have been eliminated in consolidation.
Use of Estimates	'
	Use of Estimates
	The preparation of 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. The allowance for loan and lease losses and fair values of financial instruments are particularly subject to change.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	For the purpose of the statement of cash flows, cash and due from banks and Federal funds sold are considered to be cash equivalents. Generally, Federal funds are sold for one-day periods.
Interest-Bearing Deposits in Banks	'
	Interest-Bearing Deposits in Banks
	Interest-bearing deposits in banks mature within one year and are carried at cost.
Investment Securities	'
	Investment Securities
	Investments are classified into the following categories:
		●	Available-for-sale securities, reported at fair value, with unrealized gains and losses excluded from earnings and reported, net of taxes, as accumulated other comprehensive income (loss) within shareholders’ equity.
		●	Held-to-maturity securities, which management has the positive intent and ability to hold to maturity, reported at amortized cost, adjusted for the accretion of discounts and amortization of premiums.
	Management determines the appropriate classification of its investments at the time of purchase and may only change the classification in certain limited circumstances. All transfers between categories are accounted for at fair value. There were no transfers during the years ended December 31, 2013 and 2012.
	Gains or losses on the sale of investment securities are computed on the specific identification method. Interest earned on investment securities is reported in interest income, net of applicable adjustments for accretion of discounts and amortization of premiums.
	An investment security is impaired when its carrying value is greater than its fair value. Investment securities that are impaired are evaluated on at least a quarterly basis and more frequently when economic or market conditions warrant such an evaluation to determine whether a decline in their value is other than temporary. Management utilizes criteria such as the magnitude and duration of the decline and the intent and ability of the Company to retain its investment in the securities for a period of time sufficient to allow for an anticipated recovery in fair value, in addition to the reasons underlying the decline, to determine whether the loss in value is other than temporary. The term “other than temporary” is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value is not necessarily favorable, or that there is a lack of evidence to support a realizable value equal to or greater than the carrying value of the investment. For debt securities, once a decline in value is determined to be other than temporary and management does not intend to sell the security or it is more likely than not that management will not be required to sell the security before recovery, only the portion of the impairment loss representing credit exposure is recognized as a charge to earnings, with the balance recognized as a charge to other comprehensive income. If management intends to sell the security or it is more likely than not that management will be required to sell the security before recovering its forecasted cost, the entire impairment loss is recognized as a charge to earnings. For equity securities, the entire amount of impairment is recognized through earnings.
Federal Home Loan Bank Stock	'
	Federal Home Loan Bank Stock
	Investments in Federal Home Loan Bank of San Francisco (the “FHLB”) stock are carried at cost and are redeemable at par with certain restrictions. Investments in FHLB stock are necessary to participate in FHLB programs.
Loans and Leases	'
	Loans and Leases
	Loans and leases that management has both the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal amounts outstanding, adjusted for unearned income, deferred loan origination fees and costs, purchase premiums and discounts, write-downs and the allowance for loan and lease losses. Loan and lease origination fees, net of certain deferred origination costs, and purchase premiums and discounts are recognized as an adjustment to the yield of the related loans and leases.
	For all classes of loans and leases, the accrual of interest is discontinued when, in the opinion of management, there is an indication that the borrower may be unable to meet payment requirements within an acceptable time frame relative to the terms stated in the loan agreement. Upon such discontinuance, all unpaid accrued interest is reversed against current income unless the loan or lease is well secured and in the process of collection. Interest received on nonaccrual loans and leases is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Generally, loans and leases are restored to accrual status when the obligation is brought current and has performed in accordance with the contractual terms for a reasonable period of time and the ultimate collectability of the total contractual principal and interest is no longer in doubt.
	Direct financing leases are carried net of unearned income. Income from leases is recognized by a method that approximates a level yield on the outstanding net investment in the lease.
Loan Sales and Servicing	'
	Loan Sales and Servicing
	Included in the loan and lease portfolio are Small Business Administration (“SBA”) loans and Farm Service Agency guaranteed loans that may be sold in the secondary market. At the time the loan is sold, the related right to service the loan is either retained, with the Company earning future servicing income, or released in exchange for a one-time servicing-released premium. Loans subsequently transferred to the loan portfolio are transferred at the lower of cost or fair value at the date of transfer. Any difference between the carrying amount of the loan and its outstanding principal balance is recognized as an adjustment to yield by the interest method. There were no loans held for sale at December 31, 2013 and 2012.
	SBA and Farm Service Agency loans with unpaid balances of $269,000 and $328,000 were being serviced for others as of December 31, 2013 and 2012, respectively. The Company also serviced loans that are participated with other financial institutions totaling $8,320,000 and $10,108,000 as of December 31, 2013 and 2012, respectively.
	Servicing rights acquired through 1) a purchase or 2) the origination of loans which are sold or securitized with servicing rights retained are recognized as separate assets or liabilities. Servicing assets or liabilities are initially recorded at fair value and are subsequently amortized in proportion to and over the period of the related net servicing income or expense. Servicing assets are periodically evaluated for impairment. Servicing assets were not considered material for disclosure purposes at December 31, 2013 and 2012.
Allowance for Loan and Lease Losses	'
	Allowance for Loan and Lease Losses
	The allowance for loan and lease losses is an estimate of probable credit losses inherent in the Company’s credit portfolio that have been incurred as of the balance-sheet date. The allowance is established through a provision for loan and lease losses which is charged to expense. Additions to the allowance are expected to maintain the adequacy of the total allowance after credit losses and loan growth. Credit exposures determined to be uncollectible are charged against the allowance. Cash received on previously charged off amounts is typically recorded as a recovery to the allowance. The overall allowance consists of two primary components, specific reserves related to impaired credits and general reserves for inherent probable losses related to credits that are not impaired.
	For all classes of the portfolio, a loan or lease is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the original agreement. Impaired loans are individually evaluated to determine the extent of impairment, if any, except for smaller-balance loans that are collectively evaluated for credit risk. When a loan or lease is impaired, the Company measures impairment based on the present value of expected future cash flows discounted at the credit’s original interest rate, except that as a practical expedient, it may measure impairment based on a credit’s observable market price, or the fair value of the collateral if the credit is collateral dependent. A loan or lease is collateral dependent if the repayment of the credit is expected to be provided solely by the sale or operation of the underlying collateral.
	For all portfolio segments, a restructuring of a debt constitutes a troubled debt restructuring (“TDR”) if the Company grants a concession to the borrower for economic or legal reasons related to the borrower’s financial difficulties that it would not otherwise consider. Restructured workout loans typically present an elevated level of credit risk as the borrowers are not able to perform according to the original contractual terms. Loans or leases that are reported as TDRs are considered impaired and measured for impairment as described above.
	For all portfolio segments, the determination of the general reserve for loans and leases that are not impaired is based on estimates made by management, to include, but not limited to, consideration of historical losses by portfolio segment, internal asset classifications, and qualitative factors to include economic trends in the Company’s service areas, industry experience and trends, geographic concentrations, estimated collateral values, the Company’s underwriting policies, the character of the credit portfolio, and probable losses inherent in the portfolio taken as a whole.
	The Company determines a separate allowance for each portfolio segment. These portfolio segments include commercial, real estate construction (including land and development loans), residential real estate, multi-family real estate, commercial real estate, leases, agriculture and consumer loans. The allowance for loan and lease losses attributable to each portfolio segment, which includes both impaired credits and credits that are not impaired, is combined to determine the Company’s overall allowance, which is included as a component of loans and leases on the consolidated balance sheet and available for all loss exposures.
	The Company assigns a risk rating to all loans and periodically performs detailed reviews of all such loans over a certain threshold to identify credit risks and to assess the overall collectability of the portfolio. These risk ratings are also subject to examination by independent specialists engaged by the Company and the Company’s regulators. During the internal reviews, management monitors and analyzes the financial condition of borrowers and guarantors, trends in the industries in which borrowers operate and the fair values of collateral securing these loans. These credit quality indicators are used to assign a risk rating to each individual credit. The risk ratings can be grouped into six major categories, defined as follows:
	Pass – A pass loan is a strong credit with no existing or known potential weaknesses deserving of management’s close attention.
	Watch – A watch credit is a loan or lease that otherwise meets the definition of a standard or minimum acceptable quality loan, but which requires more than normal attention due to any of the following items: deterioration of borrower financial condition less severe than those warranting more adverse grading, deterioration of repayment ability and/or collateral value, increased leverage, adverse effects from a downturn in the economy, local market or industry, adverse changes in local or regional employer, management changes (including illness, disability, and death), and adverse legal action. Payments are current per the terms of the agreement. If conditions persist or worsen, a more severe risk grade may be warranted.
	Special Mention – A special mention credit is a loan or lease that has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the credit or in the Company’s position at some future date. Special Mention credits are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.
	Substandard – A substandard credit is a loan or lease that is not adequately protected by the current sound worth and paying capacity of the borrower or the value of the collateral pledged, if any. Credits classified as substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Well defined weaknesses include inadequate cash flow or collateral support, a project’s lack of marketability, failure to complete construction on time or a project’s failure to fulfill economic expectations. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
	Doubtful – Credits classified as doubtful are loans or leases that have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions and values, highly questionable and improbable.
	Loss – Credits classified as loss are loans or leases considered uncollectible and charged off immediately.
	The general reserve component of the allowance for loan and lease losses also consists of reserve factors that are based on management’s assessment of the following for each portfolio segment: (1) inherent credit risk, (2) historical losses and (3) other qualitative factors. These reserve factors are inherently subjective and are driven by the repayment risk associated with each portfolio segment described below.
	Real Estate- Commercial – Commercial real estate mortgage loans generally possess a higher inherent risk of loss than other real estate portfolio segments, except land and construction loans. Adverse economic developments or an overbuilt market impact commercial real estate projects and may result in troubled loans. Trends in vacancy rates of commercial properties impact the credit quality of these loans. High vacancy rates reduce operating revenues and the ability for properties to produce sufficient cash flow to service debt obligations.
	Real Estate- Construction – These loans generally possess a higher inherent risk of loss than other real estate portfolio segments. A major risk arises from the necessity to complete projects within specified cost and time lines. Trends in the construction industry significantly impact the credit quality of these loans, as demand drives construction activity. In addition, trends in real estate values significantly impact the credit quality of these loans, as property values determine the economic viability of construction projects.
	Real Estate- Multi-family – Multi-family loans are non-construction term mortgages for the acquisition, refinance, or improvement of residential rental properties with generally more than 4 dwelling units. Underwriting is generally based on borrower creditworthiness, sufficiency of net operating income to service the bank loan payment, and a prudent loan-to-value ratio, among other factors.
	Real Estate- Residential – Residential loans are generally loans to purchase or refinance 1-4 unit single-family residences, either owner-occupied or investor-owned. Some residential loans are short term to match their intended source of repayment through sale or refinance. The remainder are fixed or floating-rate term first mortgages with an original maturity between 2 and 10 years, generally with payments based on a 25-30 year amortization.
	Commercial – Commercial loans generally possess a lower inherent risk of loss than real estate portfolio segments because these loans are generally underwritten to existing cash flows of operating businesses. Debt coverage is provided by business cash flows and economic trends influenced by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans.
	Lease Financing Receivable – Leases originated by the bank are non-consumer finance leases (as contrasted with operating leases) for the acquisition of titled and non-titled business equipment. Leases are generally amortized over a period from 36 to 84 months, depending on the useful life of the equipment acquired. Residual (balloon) payments at lease end range from 0-20% of original cost, and are a non-optional obligation of the lessee. Lessees are contractually responsible for all costs, expenses, taxes, and liability associated with the leased equipment.
	Agricultural – Loans secured by crop production and livestock are especially vulnerable to two risk factors that are largely outside the control of the Company and borrowers: commodity prices and weather conditions.
	Consumer – The consumer loan portfolio is comprised of a large number of small loans scheduled to be amortized over a specific period. Most installment loans are made directly for consumer purchases, but business loans granted for the purchase of heavy equipment or industrial vehicles may also be included. Also included in the consumer loan portfolio are home equity lines of credit. Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate that the borrowers’ capacity to repay their obligations may be deteriorating.
	Although management believes the allowance to be adequate, ultimate losses may vary from its estimates. At least quarterly, the Board of Directors reviews the adequacy of the allowance, including consideration of the relative risks in the portfolio, current economic conditions and other factors. If the Board of Directors and management determine that changes are warranted based on those reviews, the allowance is adjusted. In addition, the Company’s primary regulators, the FDIC and the California Department of Business Oversight, as an integral part of their examination process, review the adequacy of the allowance. These regulatory agencies may require additions to the allowance based on their judgment about information available at the time of their examinations.
Allowance for Credit Losses on Off-Balance-Sheet Credit Exposures	'
	Allowance for Credit Losses on Off-Balance-Sheet Credit Exposures
	The Company also maintains a separate allowance for off-balance-sheet commitments. Management estimates probable incurred losses using historical data and utilization assumptions. The allowance for off-balance-sheet commitments is included in accrued interest payable and other liabilities on the consolidated balance sheet.
Other Real Estate Owned (OREO)	'
	Other Real Estate Owned (OREO)
	Other real estate owned includes real estate acquired in full or partial settlement of loan obligations. When property is acquired, any excess of the recorded investment in the loan balance and accrued interest income over the estimated fair market value of the property less estimated selling costs is charged against the allowance for loan and lease losses. A valuation allowance for losses on other real estate may be maintained to provide for temporary declines in value. The valuation allowance is established through a provision for losses on other real estate which is included in other expenses. Subsequent gains or losses on sales or writedowns resulting from permanent impairments are recorded in other income or expense as incurred. During 2013, the Company received $7,475,000 in net proceeds from the sale of other real estate owned with net gains of $44,000 recognized on the sale. During 2012, the Company received $3,637,000 in net proceeds from the sale of other real estate owned with net losses of $2,000 recognized on the sale. The recorded investment in other real estate owned totaled $6,621,000 and $12,237,000 at December 31, 2013 and 2012, respectively, and had related valuation allowances of $106,000 and $175,000, respectively.
Premises and Equipment	'
	Premises and Equipment
	Premises and equipment are carried at cost. Depreciation is determined using the straight-line method over the estimated useful lives of the related assets. The useful life of the building and improvements is forty years. The useful lives of furniture, fixtures and equipment are estimated to be three to ten years. Leasehold improvements are amortized over the life of the asset or the term of the related lease, whichever is shorter. When assets are sold or otherwise disposed of, the cost and related accumulated depreciation or amortization are removed from the accounts, and any resulting gain or loss is recognized in income for the period. The cost of maintenance and repairs is charged to expense as incurred. Impairment of long-lived assets is evaluated by management based upon an event or changes in circumstances surrounding the underlying assets which indicate long-lived assets may be impaired.
Goodwill and Intangible Assets	'
	Goodwill and Intangible Assets
	Business combinations involving the Company’s acquisition of equity interests or net assets of another enterprise or the assumption of net liabilities in an acquisition of branches constituting a business may give rise to goodwill. Goodwill represents the excess of the cost of an acquired entity over the net of the amounts assigned to assets acquired and liabilities assumed. The value of goodwill is ultimately derived from the Company’s ability to generate net earnings after the acquisition and is not deductible for tax purposes. A decline in net earnings could be indicative of a decline in the fair value of goodwill and result in impairment. For that reason, goodwill is assessed for impairment at least annually. Impairment exists when a reporting unit’s carrying value of goodwill exceeds its fair value. At December 31, 2013, the Company had one reporting unit and that reporting unit had positive equity and the Company elected to perform a qualitative assessment to determine if it was more likely than not that the fair value of the reporting unit exceeded its carrying value, including goodwill. The qualitative assessment indicated that it was more likely than not that the fair value of the reporting unit exceeded its carrying value, resulting in no impairment.
	Intangible assets are comprised of core deposit intangibles which represent the estimated fair value of the long-term deposit relationships that were assumed when the Company acquired Bank of Amador in December 2004. Core deposit intangibles are amortized over a period that approximates the expected run-off of the deposit base, which, in this case, is eight years. The intangible asset related to the Bank of Amador acquisition became fully amortized during 2012.
Bank-Owned Life Insurance	'
	Bank-Owned Life Insurance
	The Company has purchased life insurance policies on certain key executives. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Income Taxes	'
	Income Taxes
	The Company files its income taxes on a consolidated basis with its subsidiaries. The allocation of income tax expense represents each entity’s proportionate share of the consolidated provision for income taxes.
	The Company accounts for income taxes using the balance sheet method, under which deferred tax assets and liabilities are recognized for the tax consequences of temporary differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. The deferred provision for income taxes is the result of the net change in the deferred tax asset and deferred tax liability balances during the year. This amount combined with the current taxes payable or refundable, results in the income tax expense for the current year. On the consolidated balance sheet, net deferred tax assets are included in accrued interest receivable and other assets.
	The realization of deferred income tax assets is assessed and a valuation allowance is recorded if it is “more likely than not” that all or a portion of the deferred tax assets will not be realized. “More likely than not” is defined as greater than a 50% chance. All available evidence, both positive and negative is considered to determine whether, based on the weight of that evidence, a valuation allowance is needed. Based upon the Company’s analysis of available evidence, the Company determined that it is “more likely than not” that all of the deferred income tax assets as of December 31, 2013 and 2012 will be fully realized and therefore no valuation allowance was recorded.
	The Company uses a comprehensive model for recognizing, measuring, presenting and disclosing in the financial statements tax positions taken or expected to be taken on a tax return. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Interest expense and penalties associated with unrecognized tax benefits, if any, are classified as income tax expense in the consolidated statement of income.
Comprehensive Income	'
	Comprehensive Income
	Comprehensive income is reported in addition to net income for all periods presented. Comprehensive income is a more inclusive financial reporting methodology that includes disclosure of other comprehensive income (loss) that historically has not been recognized in the calculation of net income. Unrealized gains and losses on the Company’s available-for-sale investment securities are included in other comprehensive income (loss), adjusted for realized gains or losses included in net income. Total comprehensive income and the components of accumulated other comprehensive income (loss) are presented in the consolidated statements of comprehensive income.
Earnings Per Share	'
	Earnings Per Share
	Basic earnings per share (“EPS”), which excludes dilution, is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock, such as stock options or restricted stock, result in the issuance of common stock that share in the earnings of the Company. The treasury stock method has been applied to determine the dilutive effect of stock options and restricted stock in computing diluted EPS. Earnings and dividends per share are restated for all stock splits and stock dividends through the date of issuance of the consolidated financial statements. There were no stock splits or stock dividends in 2013, 2012 or 2011.
Stock-Based Compensation	'
	Stock-Based Compensation
	At December 31, 2013, the Company had two stock-based compensation plans, which are described more fully in Note 13. Compensation expense, net of related tax benefits, recorded in 2013, 2012 and 2011 totaled $84,000, $102,000 and $180,000, or $0.01, $0.01 and $0.02 per diluted share, respectively. Compensation expense is recognized over the vesting period on a straight line accounting basis.
	The fair value of each option award is estimated on the date of grant using a Black-Scholes-Merton based option valuation model that uses the assumptions noted in the following table. Because Black-Scholes-Merton based option valuation models incorporate ranges of assumptions for inputs, those ranges are disclosed. Expected volatilities are based on historical volatility of the Company’s stock and other factors. The Company uses historical data to estimate the dividend yield, option life and forfeiture rate within the valuation model. The expected option life represents the period of time that options granted are expected to be outstanding. The risk-free rate for the period representing the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

	Dividend yield			0	%
	Expected volatility			28.8	%
	Risk-free interest rate			1.19	%
	Expected option life in years			7
	Weighted average fair value of options granted during the year		$	2.31
	There were no options granted in 2013 or 2011 under either stock-based compensation plans.
	Restricted stock awards are grants of shares of the Company’s common stock that are subject to forfeiture until specific conditions or goals are met. Conditions may be based on continuing employment or service and/or achieving specified performance goals. During the period of restriction, Plan participants holding restricted share awards have voting and cash dividend rights. The restrictions lapse in accordance with a schedule or with other conditions determined by the Board of Directors as reflected in each award agreement. Upon the vesting of each restricted stock award, the Company issues the associated common shares from its inventory of authorized common shares. All outstanding awards under the Plan immediately vest in the event of a change of control of the Company. The shares associated with any awards that fail to vest become available for re-issuance under the Plan.
	The following is a summary of stock-based compensation information as of or for the years ended December 31, 2013, 2012 and 2011:

Operating Segments	'
	Operating Segments
	While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
Adoption of New Accounting Standards	'
	Adoption of New Accounting Standards
	In February 2013, the Financial Accounting Standards Board amended existing guidance related to reporting amounts reclassified out of other comprehensive income out of accumulated other comprehensive income.  These amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. These amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. Generally Accepted Accounting Principles (“GAAP”) to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional details about those amounts. These amendments are effective prospectively for interim and annual reporting periods beginning after December 15, 2012. The effect of adopting this standard did not have a material effect on the Company’s consolidated financial position, results of operations or cash flows.

Of the 16,207restricted common shares, 9,898 will vest one year from the date of the award and 6,309 will vest 20% per year from the date of the award.

The 2010 Plan provides for the following types of stock-based awards: incentive stock options; nonqualified stock options; stock appreciation rights; restricted stock; restricted performance stock; unrestricted Company stock; and performance units. Awards granted under the 2000 Plan were either incentive stock options or nonqualified stock options. The 2010 Plan and the 2000 Plan (collectively the “Plans”), under which equity incentives may be granted to employees and directors under incentive and nonstatutory agreements, require that the option price may not be less than the fair value of the stock at the date the option is granted. The option awards under the Plans expire on dates determined by the Board of Directors, but not later than ten years from the date of award. The vesting period is generally five years; however, the vesting period can be modified at the discretion of the Company’s Board of Directors. Outstanding option awards under the Plans are exercisable until their expiration; however, no new options will be awarded under the 2000 Plan. The Plans do not provide for the settlement of awards in cash and new shares are issued upon exercise of an option.
