See Notes to Unaudited Consolidated Financial Statements   7  AMERICAN RIVER BANKSHARESNOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTSMarch 31, 20111. CONSOLIDATED FINANCIAL STATEMENTSIn the opinion of management, the unaudited consolidated financial statements contain all adjustments  (consisting of only normal recurring adjustments) necessary to present fairly the consolidated financial position of American River Bankshares (the “Company”) at March 31, 2011 and December 31, 2010, and the results of its operations and its cash flows for the three-month periods ended March 31, 2011 and 2010 and its statement of changes in shareholders’ equity for the year ended December 31, 2010 and the three months ended March 31, 2011 in conformity with accounting principles generally accepted in the United States of America.Certain disclosures normally presented in the notes to the annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted.  The Company believes that the disclosures are adequate to make the information not misleading.  These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2010 annual report on Form 10-K.   The results of operations for the three-month period ended March 31, 2011 may not necessarily be indicative of the operating results for the full year.In preparing such financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period.  Actual results could differ significantly from those estimates.  Material estimates that are particularly susceptible to significant changes in the near term relate to the determination of the allowance for loan and lease losses, the provision for taxes and the estimated fair value of investment securities and other real estate owned.Management has determined that since all of the banking products and services offered by the Company are available in each branch office of American River Bank, all branch offices are located within the same economic environment and management does not allocate resources based on the performance of different lending or transaction activities, it is appropriate to aggregate all of the branch offices and report them as a single operating segment.  No client accounts for more than ten percent (10%) of revenues for the Company or American River Bank.2. STOCK-BASED COMPENSATION  Equity Plans 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.  In 2000, the Board of Directors adopted and the Company’s shareholders approved a stock option plan (the “2000 Plan”), under which 379,571 options remain outstanding at March 31, 2011.  The total number of authorized shares that remain available for issuance under the 2010 Plan is 1,447,495.  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.  Under the 2010 Plan, the awards may be granted to employees and directors under incentive and nonstatutory agreements and other awards agreements.  The 2010 Plan and the 2000 Plan (collectively the “Plans”) require that the option price may not be less than the fair market 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.  New shares are issued upon exercise of an option.   8  During the third quarter of 2010, the Company awarded 29,334 shares of restricted common stock under the Company’s 2010 Equity Incentive Plan to certain employees and to directors.  Grant date fair value is determined by the market price of the Company’s common stock on the date of grant. The aggregate value of these shares at the grant date amounts to approximately $205,000 and is recognized ratably as compensation expense or director expense over the vesting periods.  The shares of common stock granted pursuant to such agreements vest in increments over one to five years from the date of grant.  The shares awarded to employees and directors under the restricted stock agreements vest on the applicable vesting dates only to the extent the recipient of the shares is then an employee or a director of the Company or one of its subsidiaries, and each recipient will forfeit all of the shares that have not vested on the date his or her employment or service is terminated. New shares are issued upon vesting of the restricted common stock. Equity Compensation For the three-month periods ended March 31, 2011 and 2010, the compensation cost recognized for equity compensation was $72,000 and $55,000, respectively.  The recognized tax benefit for equity compensation expense was $20,000 and $10,000, for the three-month periods ended March 31, 2011 and 2010, respectively. At March 31, 2011, the total compensation cost related to nonvested stock option awards not yet recorded is expected to be $140,000.  This amount will be recognized over the next four years and the weighted average period of recognizing these costs is expected to be 1.5 years. At March 31, 2011, the total compensation cost related to restricted stock awards not yet recorded is expected to be $130,000.  This amount will be recognized over the next four and a half years and the weighted average period of recognizing these costs is expected to be 1.4 years. Equity Plans Activity Stock Options There were no stock options awarded during the three-month periods ended March 31, 2011 and 2010.  A summary of option activity under the Plans as of March 31, 2011 and changes during the period then ended is presented below: Options Shares  Weighted Average Exercise Price  Weighted Average Remaining Contractual Term  Aggregate Intrinsic Value ($000) Outstanding at January 1, 2011  379,571  $17.18  4.7 years  $— Granted  —   —   —   — Exercised  —   —   —   — Cancelled  —   —   —   — Outstanding at March 31, 2011  379,571  $17.18  4.4 years  $—                 Exercisable at March 31, 2011  306,943  $18.10  4.8 years  $— Restricted StockThere was no restricted stock awarded during the three month periods ended March 31, 2011 or 2010.  There were no restricted awards that were fully vested, nor were there any awards that had been forfeited during the same period and the intrinsic value at March 31, 2011 was $194,000.Other Equity AwardsThere were no stock appreciation rights; restricted performance stock; unrestricted Company stock; or performance units awarded during the three month periods ended March 31, 2011 or 2010.The intrinsic value used for stock options and restricted stock was derived from the market price of the Company’s common stock of $6.60 as of March 31, 2011.   9  3. COMMITMENTS AND CONTINGENCIESIn the normal course of business there are outstanding various commitments to extend credit which are not reflected in the financial statements, including loan commitments of approximately $41,419,000 and standby letters of credit of approximately $10,121,000 at March 31, 2011.  Such loan commitments relate primarily to real estate construction loans, revolving lines of credit and other commercial loans.  However, all such commitments will not necessarily culminate in actual extensions of credit by the Company during 2011 as some of these are expected to expire without being fully drawn upon.Standby letters of credit are commitments issued to guarantee the performance or financial obligation of a client to a third party.  These guarantees are issued primarily relating to purchases of inventory or as security for real estate rents by commercial clients and are typically short-term in nature.  Credit risk is similar to that involved in extending loan commitments to clients and accordingly, evaluation and collateral requirements similar to those for loan commitments are used.  The majority of all such commitments are collateralized.  The fair value of the liability related to these standby letters of credit, which represents the fees received for issuing the guarantees was not significant at March 31, 2011 or March 31, 2010. 4. EARNINGS PER SHARE COMPUTATIONBasic earnings per share is computed by dividing net income by the weighted average common shares outstanding for the period (9,845,533 shares for the three-month period ended March 31, 2011 and 2010).  Diluted earnings per share reflect 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.  Diluted earnings per share is computed by dividing net income by the weighted average common shares outstanding for the period plus the dilutive effect of stock based awards (8,122 shares for the three-month period ended March 31, 2011 and zero shares for the three-month period ended March 31, 2010).  Earnings per share is retroactively adjusted for stock dividends and stock splits for all periods presented.5. COMPREHENSIVE INCOMEComprehensive income is reported in addition to net income for all periods presented.  Comprehensive income is comprised of net income plus other comprehensive income.  Other comprehensive income, net of taxes, was comprised of the unrealized gains on available-for-sale investment securities of $128,000 for the three-month period ended March 31, 2011 and $966,000 for the three-month period ended March 31, 2010. Comprehensive income was $334,000 for the three-month period ended March 31, 2011 and $1,272,000 for the three-month period ended March 31, 2010.  Reclassification adjustments resulting from gain or loss on sale of investment securities were not significant for all periods presented.6.

Net unrealized gains on available-for-sale investment securities totaling $1,980,000 were recorded, net of $792,000 in tax liabilities, as accumulated other comprehensive income within shareholders’ equity at March 31, 2010.  Proceeds and gross realized gains from the sale and call of available-for-sale investment securities for the period ended March 31, 2010 totaled $314,000 and $2,000, respectively.

At March 31, 2011, the Company held 170 securities of which 20 were in a loss position for less than twelve months and 9 were in a loss position for twelve months or more.  Of the 29 securities in a loss position, 11 are mortgage-backed securities, 11 are obligations of states and political subdivisions and 7 are corporate stocks.  At December 31, 2010, the Company held 168 securities of which 29 were in a loss position for less than twelve months and 5 were in a loss position for twelve months or more.  Of the 34 securities in a loss position, 15 are mortgage-backed securities, 11 are obligations of states and political subdivisions and 8 are corporate stocks. The unrealized loss on the Company’s investments in mortgage-backed securities and obligations of states and political subdivisions 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 until maturity, management does not consider these investments to be other-than-temporarily impaired. The amortized cost and estimated fair values of investment securities at March 31, 2011 by contractual maturity are shown below (dollars in thousands).   12     Available-for-Sale  Held-to-Maturity       Estimated     Estimated    Amortized  Fair  Amortized  Fair    Cost  Value  Cost  Value               Within one year $907  $915       After one year through five years  5,079   5,190       After five years through ten years  6,093   6,193       After ten years  5,538   5,510           17,617   17,808       Investment securities not due at a single maturity date:              Mortgage-backed securities  139,337   142,195  $5,486  $5,762 Corporate stock  77   89            $157,031  $160,092  $5,486  $5,762  Expected maturities will differ from contractual maturities because the issuers of the securities may have the right to call or prepay obligations with or without call or prepayment penalties. 7. IMPAIRED AND NONPERFORMING LOANS AND LEASES AND OTHER REAL ESTATE OWNED At March 31, 2011 and December 31, 2010, the recorded investment in nonperforming loans and leases was approximately $21,595,000 and $22,571,000, respectively.  Nonperforming loans and leases include all such loans and leases that are either placed on nonaccrual status or are 90 days past due as to principal or interest but still accrue interest because such loans are well-secured and in the process of collection.  The Company considers a loan to be impaired when, based on current information and events, it is probable that it will be unable to collect all amounts due (principal and interest) according to the contractual terms of the loan agreement.  At March 31, 2011, the recorded investment in loans and leases that were considered to be impaired totaled $38,550,000, which includes $21,338,000 in nonperforming loans and leases and $17,212,000 in performing loans and leases.  Of the total impaired loans of $38,550,000, loans totaling $21,699,000 were deemed to require no specific reserve and loans totaling $16,851,000 were deemed to require a related valuation allowance of $1,035,000.  At December 31, 2010, the recorded investment in loans and leases that were considered to be impaired totaled $40,237,000 and had a related valuation allowance of $1,619,000.  If interest had been accruing on the nonperforming loans, such income would have approximated $425,000 and $302,000 for the three months ended March 31, 2011 and 2010, respectively. At March 31, 2011, there were 27 loans and leases that were considered to be troubled debt restructurings.  Of these loans and leases, 14 were modified and are currently performing (less than ninety days past due) totaling $8,215,000 and 13 are considered nonperforming (and included in the $21,595,000 noted above), totaling $6,700,000.  At March 31, 2011 and December 31, 2010, there were no unfunded commitments on those loans considered troubled debt restructures. At March 31, 2011 and December 31, 2010, the recorded investment in other real estate owned (“OREO”) was  $3,742,000 and $2,696,000, respectively.  For the three months ended March 31, 2011, the Company transferred six properties from four relationships with loan balances in the amount of $1,988,000 to OREO and subsequently wrote these balances down by $222,000 to $1,766,000, and sold three properties with balances of $554,000 for a net loss of $28,000.  In addition to the $222,000 write downs, the Company also adjusted the balances, through charges to the allowance for loan and lease losses, to properties obtained in the prior quarter in the amount of $166,000.  The  March 31, 2011 OREO balance of $3,742,000 consists of 17 properties including 7 residential land properties in the amount of $513,000, 2 commercial land properties totaling $732,000, 4 commercial real estate properties in the amount of $1,717,000 and 4 are residential real estate properties in the amount of $780,000.  Nonperforming loans and leases and OREO at March 31, 2011 and December 31, 2010 are summarized as follows:   13   (in thousands) March 31,2011  December 31,2010         Nonaccrual loans and leases that are current to terms $1,559  $3,004 Nonaccrual loans and leases that are past due  20,036   19,567 Loans and leases past due 90 days and accruing interest  —   — Other real estate owned  3,742   2,696 Total nonperforming assets $25,337  $25,267           Nonperforming loans and leases to total loans and leases  6.48%  6.52%Total nonperforming assets to total assets  4.42%  4.36% Impaired loans and leases as of and for the periods ended March 31, 2011 and December 31, 2010 are summarized as follows: March 31, 2011    Unpaid     Average  Interest (dollars in thousands) Recorded  Principal  Related  Recorded  Income    Investment  Balance  Allowance  Investment  Recognized                  With no related allowance recorded:               Commercial:               Commercial $5,460  $7,286   —  $5,243  $44 Real estate:                    Commercial  7,301   9,186   —   8,183   55 Multi-family  2,589   2,682   —   1,985   9 Construction  4,586   6,620   —   4,641   — Residential  1,478   1,776   —   1,571   8 Other:                    Agriculture  129   322   —   129   — Consumer  156   156   —   182   4    $21,699  $28,028  $—  $21,934  $120                       With an allowance recorded:                    Commercial:                    Commercial $1,209  $1,209  $30  $2,220  $16 Real estate:                    Commercial  12,880   14,169   789   12,500   81 Multi-family  —   —   —   607   — Construction  441   580   9   221   6 Residential  1,832   1,874   197   1,422   21 Other:                    Agriculture  —   —   —   —   — Consumer  489   489   10   490   6    $16,851  $18,321  $1,035  $17,460  $130 Total:                    Commercial:                    Commercial $6,669  $8,495  $30  $7,463  $60 Real estate:                    Commercial  20,181   23,355   789   20,684   136 Multi-family  2,589   2,682   —   2,592   9 Construction  5,027   7,200   9   4,861   6 Residential  3,310   3,650   197   2,993   29 Other:                    Agriculture  129   322   —   129   — Consumer  645   645   10   672   10    $38,550  $46,349  $1,035  $39,394  $250   14   December 31, 2010    Unpaid     Average  Interest (dollars in thousands) Recorded  Principal  Related  Recorded  Income    Investment  Balance  Allowance  Investment  Recognized                  With no related allowance recorded:               Commercial:               Commercial $5,026  $5,418   —  $5,042  $137 Real estate:                    Commercial  9,066   12,149   —   14,013   424 Multi-family  1,382   2,382   —   1,383   70 Construction  4,695   7,064   —   6,545   43 Residential  1,663   1,835   —   1,593   50 Other:                    Agriculture  129   322   —   206   4 Consumer  207   207   —   317   16    $22,168  $29,377  $—  $29,099  $744                       With an allowance recorded:                    Commercial:                    Commercial $3,231  $3,231  $274  $3,452  $196 Real estate:                    Commercial  12,120   12,584   1,160   9,369   456 Multi-family  1,214   1,214   22   1,321   44 Residential  1,013   1,013   152   861   51 Other:                    Consumer  491   491   11   492   24    $18,069  $18,533  $1,619  $15,495  $771                       Total:                    Commercial:                    Commercial $8,257  $8,649  $274  $8,494  $333 Real estate:                    Commercial  21,186   24,733   1,160   23,382   880 Multi-family  2,596   3,596   22   2,704   114 Construction  4,695   7,064   —   6,545   43 Residential  2,676   2,848   152   2,454   101 Other:                    Agriculture  129   322   —   206   4 Consumer  698   698   11   809   40    $40,237  $47,910  $1,619  $44,594  $1,515  8.

BORROWING ARRANGEMENTS At March 31, 2011, the Company had $20,000,000 of unsecured short-term borrowing arrangements with two of its correspondent banks. There were no advances under the borrowing arrangements as of March 31, 2011 or December 31, 2010. The Company has a line of credit available with the Federal Home Loan Bank of San Francisco (the “FHLB”) which is secured by pledged mortgage loans and investment securities. Borrowings may include overnight advances as well as loans with terms of up to thirty years. Advances (both short and long-term) totaling $12,000,000 were outstanding from the FHLB at March 31, 2011, bearing interest rates ranging from 2.08% to 3.78% and maturing between August 22, 2011 and January 13, 2014. Advances totaling $17,000,000 were outstanding from the FHLB at December 31, 2010, bearing interest rates ranging from 1.85% to 3.78% and maturing between March 11, 2011 and January 13, 2014. Remaining amounts available under the borrowing arrangement with the FHLB at March 31, 2011 and December 31, 2010 totaled $70,058,000 and $55,165,000, respectively. The increased borrowing capacity during the first quarter of 2011 resulted from the reduction in outstanding borrowings and an increase in the borrowing capacity of the pledged collateral. In addition, the Company has a secured borrowing agreement with the Federal Reserve Bank of San Francisco. The borrowing can be secured by pledging selected loans and investment securities. Borrowings generally are short-term including overnight advances as well as loans with terms up to ninety days. Amounts available under this borrowing arrangement at March 31, 2011 and December 31, 2010 were $27,842,000 and $30,702,000, respectively. There were no advances outstanding under this borrowing arrangement as of March 31, 2011 and December 31, 2010. 10. INCOME TAXES The Company files its income taxes on a consolidated basis with its subsidiaries. The allocation of income tax expense (benefit) represents each entity’s proportionate share of the consolidated provision for (benefit from) 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. On the consolidated balance sheet, net deferred tax assets are included in accrued interest receivable and other assets. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The Company recognizes accrued interest and penalties related to unrecognized tax benefits, if applicable, as a component of interest expense in the consolidated statement of income. There have been no unrecognized tax benefits or accrued interest and penalties for the three month period ended March 31, 2011.   20   11. FAIR VALUE MEASUREMENTS The carrying amounts and estimated fair values of the Company’s financial instruments are as follows (dollars in thousands):    March 31, 2011  December 31, 2010       Estimated     Estimated    Carrying  Fair  Carrying  Fair    Amount  Value  Amount  Value Financial assets:                          Cash and cash equivalents $33,678  $33,678  $31,871  $31,871 Interest-bearing deposits in banks  2,248   2,248   2,248   2,248 Investment securities  165,578   165,854   160,664   160,987                   Loans and leases, net  325,647   319,884   338,533   332,964 FHLB stock  3,348   3,348   3,486   3,486 Accrued interest receivable  1,861   1,861   1,876   1,876 Cash surrender values of life insurance policies  11,087   11,087   11,019   11,019                  Financial liabilities:                                  Deposits $465,908  $466,767  $465,122  $465,985 Short-term borrowings  7,000   7,000   7,000   7,000 Long-term borrowings  5,000   5,174   10,000   10,523 Accrued interest payable  184   184   268   268 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. 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 March 31, 2011 and December 31, 2010: Cash and cash equivalents: For cash and cash equivalents, the carrying amount is estimated to be fair value. Investment securities: For investment securities, fair values are based on quoted market prices, where available. 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. Loans and leases: For variable-rate loans and leases that reprice frequently with no significant change in credit risk, fair values are based on carrying values. The fair values for other loans and leases are estimated using discounted cash flow analyses, using interest rates being offered at each reporting date for loans and leases with similar terms to borrowers of comparable creditworthiness. The carrying amount of accrued interest receivable approximates its fair value.   21   FHLB stock: The carrying amount of FHLB stock approximates its fair value. This investment is carried at cost and is redeemable at par with certain restrictions. Cash surrender values of life insurance policies: The fair values of life insurance policies are based on cash surrender values at each reporting date as provided by insurers. Deposits: The fair values for non-maturing deposits are, by definition, equal to the amount payable on demand at the reporting date represented by their carrying amount. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow analysis with interest rates offered at each reporting date for certificates with similar remaining maturities. The carrying amount of accrued interest payable approximates its fair value. Short-term and long-term borrowings: The fair values of short-term borrowings are estimated to be the carrying amount. The fair values of long-term borrowings are estimated using a discounted cash flow analysis with interest rates currently available for similar debt instruments. Commitments to extend credit: The fair value of commitments is based on fees currently charged to enter into similar agreements, net of origination fees. These fees were not material at March 31, 2011 and December 31, 2010. The following table presents information about the Company’s assets and liabilities measured at fair value on a recurring and nonrecurring basis as of March 31, 2011 and December 31, 2010, and indicates 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 information other than the 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. 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.   22   Description Fair Value  Fair Value Measurements Using  Total Gains(Losses) (dollars in thousands)    Quoted Prices in Active Markets for Identical Assets (Level 1)  Other Observable Inputs(Level 2)  Significant UnobservableInputs(Level 3)    March 31, 2011               Assets and liabilities measured on a recurring basis:               Available-for-sale securities:               Mortgage-backed securities $142,195     $142,195       Obligations of states and political subdivisions  17,808      17,808       Corporate stock  89  $30   59       Total recurring $160,092  $30  $160,062  $—  $—                       Assets and liabilities measured on a nonrecurring basis:                    Impaired loans:                    Commercial $1,179  $—  $—  $1,179  $19 Real estate:                    Commercial  12,312   —   1,540   10,772   (22)Multi-family  —   —   —   —   — Construction  433   —   80   353   (22)Residential  1,634   —   359   1,275   295 Other:                    Leases  —   —   —   —   — Agriculture  —   —   —   —   — Consumer  479   —   —   479   — Other real estate owned  3,742   —   3,742   —   172 Total nonrecurring $19,779  $—  $5,721  $14,058  $442   December 31, 2010                    Assets and liabilities measured on a recurring basis:                    Available-for-sale securities:                    Mortgage-backed securities $138,644   —  $138,644   —   — Obligations of states and political subdivisions  15,792   —   15,792   —   — Corporate stock  79  $75   4         Total recurring $154,515  $75  $154,440  $—  $—                       Assets and liabilities measured on a nonrecurring basis:                    Impaired loans:                    Commercial $4,197  $—  $3,870  $327  $(275)Real estate:                    Commercial  18,504   —   6,388   12,116   (381)Multi-family  1,214   —   —   1,214   (93)Construction  2,298   —   2,298   —   (952)Residential  2,098   —   1,085   1,013   (162)Other:                    Leases  27   —   —   27   — Agriculture  129   —   129   —   — Consumer  490   —   —   490   109 Other real estate owned  2,696   —   2,696   —   (908)Total nonrecurring $31,653  $—  $16,466  $15,187  $(2,662)   23   There were no significant transfers between level 1and level 2 during the three months ended March 31, 2011 or the twelve months ended December 31, 2010. 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 evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information. Evaluated pricing applications apply available information, as applicable, through processes such as benchmark curves, benchmarking to similar securities, sector groupings, and matrix pricing. Impaired loans and leases - The fair value calculation for impaired loans and leases is based upon the fair values of the assets obtained through either collateral valuations or present value of future cash flows. For Level 2 impaired loans and leases, the analysis consists of a collateral analysis inclusive of an appraisal and detailed review of any mitigating factors pertaining to a complete valuation of the asset. For Level 3 impaired loans or leases, the analysis is one of determining the credit’s value based upon a review of the present value of the loan or lease’s future cash flows. Other real estate owned - Other real estate owned (“OREO”) represents real estate which the Company has title to in partial or full satisfaction of loans. At or near the time of foreclosure, the Company obtains an independent third-party appraisal and the OREO is recorded at the fair value of the real estate less costs to sell, which becomes the property’s new basis. The value of the OREO properties is periodically assessed by performing a property valuation, which could include a full or partial appraisal, and performed by either internally or by an independent third-party. 12. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In April 2011, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2011-02, Receivables (Topic 310): A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring. The new standard provides clarification on what types of loan modifications constitute a troubled debt restructuring. The new standard provides that in evaluating whether a restructuring constitutes a troubled debt restructuring, a creditor must separately conclude that both of the following exist: (a) the restructuring constitutes a concession; and (b) the debtor is experiencing financial difficulties. The Company is required to adopt the provisions of ASU No. 2011-02 in its first interim period beginning on or after June 15, 2011, which must be applied retrospectively to any restructurings that occurred during the year of adoption. The Company is currently assessing the potential effect, if any, on its financial statements. 13. OTHER MATTERS In February 2010, in connection with American River Bank’s (the “Bank”) regularly scheduled 2009 Federal Deposit Insurance Corporation (the “FDIC”) examination, the Bank entered into a Memorandum of Understanding (the “Memorandum”) with the FDIC and the California Commissioner of Financial Institutions. The Memorandum covers actions to be taken by the Board of Directors and management to (a) enhance BSA compliance; (b) reduce the Bank’s level of classified assets and further strengthen and improve the Bank’s asset quality; (c) request regulatory approval prior to paying any cash dividends; and (d) maintain the Bank’s Tier 1 Leverage capital ratio at not less than 8% and a Total Risk-Based capital ratio of not less than 11%. As of March 31, 2011, the foregoing ratios for the Bank were 12.0% and 19.8%, respectively. The Company believes that the Bank is currently in compliance in all material respects with the actions described in the Memorandum. Consequently, the Company does not expect these actions to significantly change its business strategy in any material respect; however, noncompliance with provisions of the Memorandum could result in regulatory enforcement actions that could have a material adverse effect upon the Company.   24   Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations. The following is management’s discussion and analysis of the significant changes in American River Bankshares’ (the “Company”) balance sheet accounts between December 31, 2010 and March 31, 2011 and its income and expense accounts for the three-month periods ended March 31, 2011 and 2010. The discussion is designed to provide a better understanding of significant trends related to the Company’s financial condition, results of operations, liquidity, capital resources and interest rate sensitivity. This discussion and supporting tables and the consolidated financial statements and related notes appearing elsewhere in this report are unaudited. Interest income and net interest income are presented on a fully taxable equivalent basis (FTE) within management’s discussion and analysis. Certain matters discussed or incorporated by reference in this Quarterly Report on Form 10-Q including, but not limited to, matters described in “Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations,” are “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, Section 27A of the Securities Act of 1933, as amended, and subject to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements may contain words related to future projections including, but not limited to, words such as “believe,” “expect,” “anticipate,” “intend,” “may,” “will,” “should,” “could,” “would,” and variations of those words and similar words that are subject to risks, uncertainties and other factors that could cause actual results to differ materially from those projected. Factors that could cause or contribute to such differences include, but are not limited to, the following:   ●the duration of financial and economic volatility and decline and actions taken by the United States Congress and governmental agencies, including the United States Department of the Treasury, to deal with challenges to the U.S. financial system;  ●the risks presented by a continued economic recession, which could adversely affect credit quality, collateral values, including real estate collateral, investment values, liquidity and loan originations and loan portfolio delinquency rates;  ●variances in the actual versus projected growth in assets and return on assets;  ●potential continued or increasing loan and lease losses;  ●potential increasing levels of expenses associated with resolving nonperforming assets as well as regulatory changes;  ●changes in the interest rate environment including interest rates charged on loans, earned on securities investments and paid on deposits and other borrowed funds;  ●competitive effects;  ●potential declines in fee and other noninterest income earned associated with economic factors as well as regulatory changes;  ●general economic conditions nationally, regionally, and within our operating markets could be less favorable than expected or could have a more direct and pronounced effect on us than expected and adversely affect our ability to continue internal growth at historical rates and maintain the quality of our earning assets;  ●changes in the regulatory environment including government intervention in the U.S. financial system;  ●changes in business conditions and inflation;  ●changes in securities markets, public debt markets, and other capital markets;  ●potential data processing and other operational systems failures or fraud;  ●potential continued decline in real estate values in our operating markets;  ●the effects of uncontrollable events such as terrorism, the threat of terrorism or the impact of the current military conflicts in Afghanistan and Iraq and the conduct of the war on terrorism by the United States and its allies, worsening financial and economic conditions, natural disasters, and disruption of power supplies and communications;  ●changes in accounting standards, tax laws or regulations and interpretations of such standards, laws or regulations;  ●projected business increases following any future strategic expansion could be lower than expected;  ●the goodwill we have recorded in connection with acquisitions could become impaired, which may have an adverse impact on our earnings;   25     ●the reputation of the financial services industry could experience further deterioration, which could adversely affect our ability to access markets for funding and to acquire and retain customers; and  ●the efficiencies we may expect to receive from any investments in personnel and infrastructure may not be realized. The factors set forth under “Item 1A - Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, and other cautionary statements and information set forth in this Quarterly Report on Form 10-Q should be carefully considered and understood as being applicable to all related forward-looking statements contained in this Quarterly Report on Form 10-Q, when evaluating the business prospects of the Company and its subsidiaries. Forward-looking statements are not guarantees of performance. By their nature, they involve risks, uncertainties and assumptions. The future results and shareholder values may differ significantly from those expressed in these forward-looking statements. You are cautioned not to put undue reliance on any forward-looking statement. Any such statement speaks only as of the date of this report, and in the case of any documents that may be incorporated by reference, as of the date of those documents. We do not undertake any obligation to update or release any revisions to any forward-looking statements, to report any new information, future event or other circumstances after the date of this report or to reflect the occurrence of unanticipated events, except as required by law. However, your attention is directed to any further disclosures made on related subjects in our subsequent reports filed with the Securities and Exchange Commission (the “SEC”) on Forms 10-K, 10-Q and 8-K. Critical Accounting Policies General The Company’s financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The financial information contained within our statements is, to a significant extent, financial information that is based on measures of the financial effects of transactions and events that have already occurred. We use historical loss data and the economic environment as factors, among others, in determining the inherent loss that may be present in our loan and lease portfolio. Actual losses could differ significantly from the factors that we use. In addition, GAAP itself may change from one previously acceptable method to another method. Although the economics of our transactions would be the same, the timing of events that would impact our transactions could change. Allowance for Loan and Lease Losses The allowance for loan and lease losses is an estimate of the credit loss risk in our loan and lease portfolio. The allowance is based on two basic principles of accounting: (1) “Accounting for Contingencies,” which requires that losses be accrued when it is probable that a loss has occurred at the balance sheet date and such loss can be reasonably estimated; and (2) “Accounting by Creditors for Impairment of a Loan,” which requires that losses be accrued on impaired loans based on the differences between the value of collateral, present value of future cash flows or values that are observable in the secondary market and the loan balance. The allowance for loan and lease losses is determined based upon estimates that can and do change when the actual risk, loss events, or changes in other factors, occur. The analysis of the allowance uses an historical loss view as an indicator of future losses and as a result could differ from the loss incurred in the future. If the allowance for loan and lease losses falls below that deemed adequate (by reason of loan and lease growth, actual losses, the effect of changes in risk factors, or some combination of these), the Company has a strategy for supplementing the allowance for loan and lease losses, over the short-term. For further information regarding our allowance for loan and lease losses, see “Allowance for Loan and Lease Losses Activity” discussion later in this Item 2.   26   Stock-Based Compensation The Company recognizes compensation expense over the vesting period in an amount equal to the fair value of all share-based payments which consist of stock options and restricted stock awarded to directors and employees. The fair value of each award is estimated on the date of grant and amortized over the service period using a Black-Scholes-Merton based option valuation model that requires the use of assumptions. Critical assumptions that affect the estimated fair value of each award include expected stock price volatility, dividend yields, option life and the risk-free interest rate. Goodwill Business combinations involving the Company’s acquisition of the equity interests or net assets of another enterprise or the assumption of net liabilities in an acquisition of branch offices 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 in transactions accounted for under the purchase method of accounting. The value of goodwill is ultimately derived from the Company’s ability to generate net earnings after the acquisition. 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 a reporting unit level at least annually following the year of acquisition. The Company performed an evaluation of goodwill, recorded as a result of the Bank of Amador acquisition, during the fourth quarter of 2010 and determined that there was no impairment. While the Company believes all assumptions utilized in its assessment of goodwill for impairment are reasonable and appropriate, changes in earnings, the effective tax rate, historical earnings multiples and the cost of capital could all cause different results for the calculation of the present value of future cash flows upon which the assessment is based. Income Taxes The Company files its income taxes on a consolidated basis with its subsidiaries. The allocation of income tax expense (benefit) represents each entity’s proportionate share of the consolidated provision for (benefit from) 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. On the consolidated balance sheet, net deferred tax assets are included in accrued interest receivable and other assets. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The Company recognizes accrued interest and penalties related to unrecognized tax benefits, if applicable, as a component of interest expense in the consolidated statement of income. There have been no unrecognized tax benefits or accrued interest and penalties for the three month period ended March 31, 2011. General Development of Business The Company is a bank holding company registered under the Bank Holding Company Act of 1956, as amended. The Company was incorporated under the laws of the State of California in 1995. As a bank holding company, the Company is authorized to engage in the activities permitted under the Bank Holding Company Act of 1956, as amended, and regulations thereunder. Its principal office is located at 3100 Zinfandel Drive, Suite 450, Rancho Cordova, California 95670 and its telephone number is (916) 854-0123. The Company employed an equivalent of 111 full-time employees as of March 31, 2011. The Company owns 100% of the issued and outstanding common shares of its banking subsidiary, American River Bank (the “Bank”), and American River Financial, a California corporation which has been inactive since its incorporation in 2003.   27   American River Bank was incorporated and commenced business in Fair Oaks, California, in 1983 and thereafter moved its headquarters to Sacramento, California in 1985. American River Bank operates five full service offices in Sacramento and Placer Counties including the main office located at 1545 River Park Drive, Suite 107, Sacramento and branch offices in Sacramento, Fair Oaks, and Roseville. American River Bank also operates two full service offices in Sonoma County in Healdsburg and Santa Rosa, operated under the name “North Coast Bank, a division of American River Bank.” North Coast Bank was incorporated and commenced business in 1990 as Windsor Oaks National Bank in Windsor, California. In 1997, the name was changed to North Coast Bank. In 2000, North Coast Bank was acquired by the Company as a separate bank subsidiary. Effective December 31, 2003, North Coast Bank was merged with and into American River Bank. On December 3, 2004, the Company acquired Bank of Amador located in Jackson, California. Bank of Amador was merged with and into American River Bank and now operates three full service banking offices in Amador County in Jackson, Pioneer, and Ione, operating as “Bank of Amador, a division of American River Bank.” The Bank’s deposits are insured by the Federal Deposit Insurance Corporation (the “FDIC”) up to applicable legal limits. On July 21, 2010, President Obama signed the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”). The Dodd-Frank Act includes a permanent increase to $250,000 as the maximum FDIC insurance limit per depositor retroactive to January 1, 2008 and the extension of unlimited FDIC insurance for noninterest-bearing transaction accounts effective December 31, 2010 through December 31, 2012. On November 9, 2010, the FDIC implemented a final rule to increase the coverage and extension of FDIC insurance under the Dodd-Frank Act. FDIC insurance coverage and assessments are discussed under “Item 1A--Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010. American River Bank does not offer trust services or international banking services and does not plan to do so in the near future. American River Bank’s primary business is serving the commercial banking needs of small to mid-sized businesses within those counties listed above. American River Bank accepts checking and savings deposits, offers money market deposit accounts and certificates of deposit, makes secured and unsecured commercial, secured real estate, and other installment and term loans and offers other customary banking services. American River Bank also conducts lease financing for most types of business equipment. American River Bank owns 100% of two inactive companies, ARBCO and American River Mortgage. ARBCO was formed in 1984 to conduct real estate development and has been inactive since 1995. American River Mortgage has been inactive since its formation in 1994. During 2011, the Company conducted no significant activities other than holding the shares of its subsidiaries. However, it is authorized, with the prior approval of the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”), the Company’s principal regulator, to engage in a variety of activities which are deemed closely related to the business of banking. The common stock of the Company is registered under the Securities Exchange Act of 1934, as amended, and is listed and traded on the Nasdaq Global Select Market under the symbol “AMRB.” Overview The Company recorded net income of $206,000 for the quarter ended March 31, 2011, which was $100,000 (32.7%) below the $306,000 reported for the same period of 2010. Diluted earnings per share for the first quarter of 2011 were $0.02 compared to $0.03 recorded in the first quarter of 2010. The return on average equity (ROAE) and the return on average assets (ROAA) for the first quarter of 2011 were 0.93% and 0.14%, respectively, as compared to 1.41% and 0.21%, respectively, for the same period in 2010. Total assets of the Company decreased by $5,600,000 (1.0%) from $578,940,000 at December 31, 2010 to $573,340,000 at March 31, 2011. Net loans totaled $325,647,000 at March 31, 2011, down $12,886,000 (3.8%) from $338,533,000 at December 31, 2010. Deposit balances at March 31, 2011 totaled $465,908,000, up slightly from the $465,122,000 at December 31, 2010. The Company ended the first quarter of 2011 with a Tier 1 capital ratio of 12.8% and a total risk-based capital ratio of 21.0% compared to 12.6% and 20.3%, respectively, at December 31, 2010. Table One below provides a summary of the components of net income for the periods indicated (See the “Results of Operations” section that follows for an explanation of the fluctuations in the individual components).   28   Table One: Components of Net Income     For the three months   ended March 31 (dollars in thousands) 2011  2010 Net interest income* $5,279  $5,829 Provision for loan losses  (1,375)  (1,641)Noninterest income  433   461 Noninterest expense  (4,051)  (4,185)Provision for income taxes  (30)  (101)Tax equivalent adjustment  (50)  (57)         Net income $206  $306           Average total assets $576,622  $584,343 Net income (annualized) as a percentage of average total assets  0.14%  0.21%          * Fully taxable equivalent basis (FTE) Results of Operations Net Interest Income and Net Interest Margin Net interest income represents the excess of interest and fees earned on interest earning assets (loans and leases, securities, Federal funds sold and investments in time deposits) over the interest paid on interest-bearing deposits and borrowed funds. Net interest margin is net interest income expressed as a percentage of average earning assets. The Company’s net interest margin was 4.24% for the three months ended March 31, 2011 down 49 basis points from 4.73% for the three months ended March 31, 2010. The fully taxable equivalent interest income component for the first quarter of 2011 decreased $767,000 (11.3%) to $6,004,000 compared to $6,771,000 for the three months ended March 31, 2010. The decrease in the fully taxable equivalent interest income for the first quarter of 2011 compared to the same period in 2010 is broken down by rate (down $421,000) and volume (down $346,000). The rate decrease can be attributed to the overall lower interest rate environment, forgone interest on nonaccrual loans, and lower average loans replaced with higher average investment securities. During the first quarter of 2011, foregone interest income on nonaccrual loans was approximately $425,000, compared to foregone interest of $302,000 during the first quarter of 2010. The foregone interest of $425,000 had a 34 basis point negative impact on the yield on earning assets. The average balance of earning assets increased 1.0% from $500,142,000 in the first quarter of 2010 to $505,041,000 in the first quarter of 2011. The overall increase in average assets during the three-month period was predominately related to an increase in investment securities offset by a decrease in loans. When compared to the first quarter of 2010, average investment securities were up $43,298,000 (35.5%) to $165,123,000 for the first quarter of 2011 and average loan balances were down $40,647,000 (10.7%) to $337,670,000 for the first quarter of 2011. Non-earning cash and principal reductions from loan balances were invested into investment securities. The change in the mix of assets, caused by a reduction in loan balances and an increase in lower yielding investment security balances, contributed to the decrease in the net interest margin. The overall low interest rate environment, the negative effect of the foregone interest on loans, and the change in the asset mix resulted in a 67 basis point decrease in the yield on average earning assets from 5.49% for 2010 to 4.82% for 2011. The volume decrease of $346,000 occurred mainly as a result of the decrease in average loans. The market in which the Company operates continues to see a slowdown in new loan volume as existing and potential new borrowers continue to pay down debt and delay expansion plans.   29   Interest expense was $217,000 (11.3%) lower in the first quarter of 2011 versus the first quarter of 2010. The average balances on interest bearing liabilities were $18,802,000 (5.3%) lower in the first quarter of 2011 compared to the same quarter in 2010. The lower balances accounted for a $99,000 decrease in interest expense for the same periods. Average borrowings were down $8,167,000 (34.8%) and average time deposits balances were down $21,399,000 (16.7%) during the first quarter of 2010 compared to the first quarter of 2011. The Company focused its marketing efforts on replacing higher cost borrowings and time deposits with lower cost checking and money market accounts. Despite the drop in average time deposits, average total deposit balances increased slightly from $466,225,000 during the first quarter of 2010 to $466,234,000 during the first quarter of 2011. The Company continues to have success attracting new deposit relationships as a direct result of its business development efforts. As a result of the lower overall interest rate environment, the decrease in rates accounted for a $118,000 reduction in interest expense for the three-month period ended March 31, 2011 compared to the same quarter in 2010. Rates paid on interest bearing liabilities decreased 19 basis points from 1.03% to 0.84% for the first quarter of 2010 compared to the first quarter of 2011. Table Two, Analysis of Net Interest Margin on Earning Assets, and Table Three, Analysis of Volume and Rate Changes on Net Interest Income and Expenses, are provided to enable the reader to understand the components and trends of the Company’s interest income and expenses. Table Two provides an analysis of net interest margin on earning assets setting forth average assets, liabilities and shareholders’ equity; interest income earned and interest expense paid and average rates earned and paid; and the net interest margin on earning assets. Table Three sets forth a summary of the changes in interest income and interest expense from changes in average asset and liability balances (volume) and changes in average interest rates.

Provision for Loan and Lease Losses The Company provided $1,375,000 for loan and lease losses for the first quarter of 2011 as compared to $1,641,000 for the first quarter of 2010. Net loan and lease losses for the three months ended March 31, 2011 were $1,598,000 or 1.92% (on an annualized basis) of average loans and leases as compared to $1,170,000 or 1.25% (on an annualized basis) of average loans and leases for the three months ended March 31, 2010. The Company has continued to provide significant amounts to the reserve for loan and lease losses for 2011 resulting from a continued high level of nonperforming loans and leases. The high level of nonperforming loans and leases is due to the impact that the overall challenging economy in the Company’s market areas and the United States, overall, has had on the Company’s borrowers. Although loan charge-offs increased from 2010 to 2011, the provision for loan and lease losses decreased for the three months ended March 31, 2011 compared to the three months ended March 31, 2010. The majority of the loans charged off in the first three months of 2011 had specific reserves and those reserves were reduced as the loan balances were partially charged off. At March 31, 2011, specific reserves were $1,035,000 compared to $1,619,000 as of December 31, 2010. For additional information see the “Allowance for Loan and Lease Losses Activity.”   31   Noninterest Income Table Four below provides a summary of the components of noninterest income for the periods indicated (dollars in thousands): Table Four: Components of Noninterest Income     Three Months Ended March 31,    2011  2010 Service charges on deposit accounts $197  $233 Gain on sale of securities  2   2 Merchant fee income  102   97 Bank owned life insurance  68   59 Other  64   70 Total noninterest income $433  $461  Noninterest income decreased $28,000 (6.1%) to $433,000 for the three months ended March 31, 2011 as compared to $461,000 for the three months ended March 31, 2010. The decrease from the first quarter of 2010 to the first quarter of 2011 was primarily related to a decline in service charge income of $36,000 or 15.5% due to a decrease in fees from overdraft charges. Noninterest Expense Noninterest expense decreased $134,000 (3.2%) to a total of $4,051,000 in the first quarter of 2011 versus $4,185,000 in the first quarter of 2010. Salary and employee benefits expense increased $86,000 (4.3%) from $1,994,000 during the first quarter of 2010 to $2,080,000 during the first quarter of 2011. The increase in salary and employee benefits expense was due in part to a decrease in direct costs associated with the production of new loans and higher employer taxes and group insurance. The Company allocates the direct costs of originating loans as a credit to salary expense in accordance with generally accepted accounting principles. As loan volume decreases there are less direct costs of loan production charged against salary expense. The offset from direct cost reimbursement decreased $23,000 (22.1%) from $104,000 in 2010 to $81,000 in 2011. Taxes and insurance increased $43,000 (14.1%) from $306,000 in the first quarter of 2010 to $349,000 in the first quarter of 2011. Overall salary expense increased $12,000 (0.8%). On a quarter-over-quarter basis, occupancy expense decreased $53,000 (16.0%) and furniture and equipment expense decreased $11,000 (5.6%). FDIC assessments decreased $21,000 (6.6%) during 2011 to $298,000, from $319,000 in 2010. Other expense decreased $135,000 (10.1%) to a total of $1,208,000 in the first quarter of 2011 versus $1,343,000 in the first quarter of 2010. Much of the Other expense decrease is related to lower costs associated with maintaining the Company’s other real estate owned (“OREO”) properties. The total OREO expense in the first quarter of 2011 was $179,000 compared to $381,000 for the same period in 2010. Much of this OREO decrease is related to lower valuation allowances in 2011 as compared to 2010. The fully taxable equivalent efficiency ratio for the first quarter of 2011 increased to 69.96% from 65.56% for the first quarter of 2010. Provision for Income Taxes Federal and state income taxes for the quarter ended March 31, 2011 decreased $71,000 (70.3%) to $30,000, compared to $101,000 in the first quarter of 2010. The decrease was primarily related to the lower level of taxable income. The effective tax rate for the quarter ended March 31, 2011 was 12.7%, a decrease from 24.8% for the first quarter of 2010. The lower effective tax rate in 2011 results from the Company realizing the benefits of tax-free income related to such items as municipal bonds and bank owned life insurance against an overall lower amount of taxable income.Balance Sheet Analysis The Company’s total assets were $573,340,000 at March 31, 2011 as compared to $578,940,000 at December 31, 2010, representing a decrease of $5,600,000 (1.0%). The average assets for the three months ended March 31, 2011 were $576,622,000, which represents a decrease of $7,721,000 or 1.3% over the balance of $584,343,000 during the three-month period ended March 31, 2010.   32   Investment Securities The Company classifies its investment securities as available-for-sale or held-to-maturity. The Company’s intent is to hold all securities classified as held-to-maturity until maturity and management believes that it has the ability to do so. Securities available-for-sale may be sold to implement asset/liability management strategies and in response to changes in interest rates, prepayment rates and similar factors. During the first quarter of 2011, the Company used the proceeds from loan paydowns and maturities and principal payments from investment securities to purchase mortgage backed-securities and municipal bonds. Table Five below summarizes the values of the Company’s investment securities held on March 31, 2011 and December 31, 2010. Table Five: Investment Securities Composition      (dollars in thousands)             Available-for-sale (at fair value) March 31, 2011  December 31,2010 Debt securities:      Mortgage-backed securities $142,195  $138,644 Obligations of states and political subdivisions  17,808   15,792 Corporate stock  89   79 Total available-for-sale investment securities $160,092  $154,515 Held-to-maturity (at amortized cost)         Debt securities:        Mortgage-backed securities $5,486  $6,149 Total held-to-maturity investment securities $5,486  $6,149  Management periodically evaluates each investment security in a loss position for other than temporary impairment relying primarily on industry analyst reports, observation of market conditions and interest rate fluctuations. Management has the ability and intent to hold securities with established maturity dates until recovery of fair value, which may be until maturity, and believes it will be able to collect all amounts due according to the contractual terms for all of the underlying investment securities; therefore, management does not consider these investments to be other-than-temporarily-impaired. Loans and Leases The Company concentrates its lending activities in the following principal areas: (1) commercial; (2) commercial real estate; (3) multi-family real estate; (4) real estate construction (both commercial and residential); (5) residential real estate; (6) lease financing receivable; (7) agriculture; and (8) consumer loans. The Company’s continuing focus in our market area, new borrowers developed through the Company’s marketing efforts, and credit extensions expanded to existing borrowers resulted in the Company originating $6 million in new loans during the first three months of 2011. Normal pay downs, loan charge-offs, and loans transferred to OREO resulted in an overall decrease in total loans and leases of $13,132,000 (3.8%) from December 31, 2010. The market in which the Company operates continues to see a slowdown in new loan volume as existing borrowers continue to pay down debt and delay expansion plans. Table Six below summarizes the composition of the loan portfolio as of March 31, 2011 and December 31, 2010.   33   Table Six: Loan and Lease Portfolio Composition(dollars in thousands) March 31, 2011  December 31, 2010  Change in   Percentage   $  %  $  %  dollars  change Commercial $51,821   16% $58,261   17% $(6,440)  (11.1%)Real estate                        Commercial  211,168   63%  216,076   62%  (4,908)  (2.3%)Multi-family  8,606   3%  6,968   2%  1,638   23.5%Construction  14,544   4%  15,971   5%  (1,427)  (8.9%)Residential  24,866   7%  26,099   7%  (1,233)  (4.7%)Lease financing receivable  2,384   1%  2,766   1%  (382)  (13.8%)Agriculture  7,361   2%  7,202   2%  159   2.2%Consumer  12,663   4%  13,202   4%  (539)  (4.1%)Total loans and leases  333,413   100%  346,545   100%  (13,132)  (3.8%)Deferred loan and lease fees, net  (404)      (427)      23     Allowance for loan and lease losses  (7,362)      (7,585)      223     Total net loans and leases $325,647      $338,533      $(12,886)  (3.8%)A significant portion of the Company’s loans and leases are direct loans and leases made to individuals and local businesses. The Company relies substantially on local promotional activity and personal contacts by American River Bank officers, directors and employees to compete with other financial institutions. The Company makes loans and leases to borrowers whose applications include a sound purpose and a viable primary repayment source, generally supported by a secondary source of repayment. Commercial loans consist of credit lines for operating needs, loans for equipment purchases, working capital, and various other business loan products. Consumer loans include a range of traditional consumer loan products such as personal lines of credit and homeowner equity lines of credit and loans to finance purchases of autos, boats, recreational vehicles, mobile homes and various other consumer items. Construction loans are generally comprised of commitments to customers within the Company’s service area for construction of commercial properties, multi-family properties and custom and semi-custom single-family residences. Other real estate loans consist primarily of loans secured by first trust deeds on commercial, multi-family, and residential properties typically with maturities from 3 to 10 years and original loan-to-value ratios generally from 65% to 75%. Agriculture loans consist primarily of vineyard loans and development loans to plant vineyards. In general, except in the case of loans under SBA programs or Farm Services Agency guarantees, the Company does not make long-term mortgage loans. “Subprime” real estate loans generally refer to residential mortgages made to higher-risk borrowers with lower credit and/or income histories. Within the industry, many of these loans were originated with adjustable interest rates that reset upward after an introductory period. These “subprime” loans coupled with declines in housing prices have led to an increase in the banking industry’s default rates resulting in many instances of increased foreclosure rates as the adjustable interest rates reset to higher levels. The Company did not have any such “subprime” loans at March 31, 2011 and December 31, 2010. Risk Elements The Company assesses and manages credit risk on an ongoing basis through a total credit culture that emphasizes excellent credit quality, extensive internal monitoring and established formal lending policies. Additionally, the Company contracts with an outside loan review consultant to periodically review the existing loan and lease portfolio. Management believes its ability to identify and assess risk and return characteristics of the Company’s loan and lease portfolio is critical for profitability and growth. Management strives to continue its emphasis on credit quality in the loan and lease approval process, through active credit administration and regular monitoring. With this in mind, management has designed and implemented a comprehensive loan and lease review and grading system that functions to continually assess the credit risk inherent in the loan and lease portfolio. The Company is taking actions to further strengthen and improve its asset quality in accordance with recommendations arising out of its 2009 regulatory examination including, among other matters, enhancement of existing procedures for appraisals and re-appraisals on secured loans and other real estate owned, and problem loan identification, including identification of impaired loans and leases and identification of troubled debt restructured loans. See also “Note 13— OTHER MATTERS,” for more information regarding the Memorandum entered into with the FDIC and the California Commissioner of Financial Institutions.   34   Ultimately, underlying trends in economic and business cycles influence credit quality. American River Bank’s business is concentrated in the Sacramento Metropolitan Statistical Area, which is a diversified economy, but with a large State of California government presence and employment base, in Sonoma County, through North Coast Bank, a division of American River Bank, whose business is focused on businesses within the two communities in which it has offices (Santa Rosa and Healdsburg) and in Amador County, through Bank of Amador, a division of American River Bank, whose business is focused on businesses and consumers within the three communities in which it has offices (Jackson, Pioneer, and Ione) as well as a diversified residential construction loan business in numerous Northern California counties. The economy of Sonoma County is diversified with professional services, manufacturing, agriculture and real estate investment and construction, while the economy of Amador County is reliant upon government, services, retail trade, manufacturing industries and Indian gaming. The Company has significant extensions of credit and commitments to extend credit that are secured by real estate. The ultimate repayment of these loans is generally dependent on personal or business cash flows or the sale or refinancing of the real estate. The Company monitors the effects of current and expected market conditions and other factors on the collectability of real estate loans. The more significant factors management considers involve the following: lease rate and terms, vacancy rates, absorption and sale rates and capitalization rates; real estate values, supply and demand factors, and rates of return; operating expenses; inflation and deflation; and sufficiency of repayment sources independent of the real estate including, in some instances, personal guarantees. In extending credit and commitments to borrowers, the Company generally requires collateral and/or guarantees as security. The repayment of such loans is expected to come from cash flow or from proceeds from the sale of selected assets of the borrowers. The Company’s requirement for collateral and/or guarantees is determined on a case-by-case basis in connection with management’s evaluation of the creditworthiness of the borrower. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, income-producing properties, residences and other real property. The Company secures its collateral by perfecting its security interest in business assets, obtaining deeds of trust, or outright possession among other means. In management’s judgment, a concentration exists in real estate loans, which represented approximately 77.7% of the Company’s loan and lease portfolio at March 31, 2011, an increase from 76.5% at December 31, 2010. Management believes that the residential land and residential construction portion of the Company’s loan portfolio carries more than the normal credit risk it has seen in the past several years, due primarily to severely curtailed demand for new and resale residential property, a large supply of unsold residential land and new and resale homes, and observed reductions in values throughout the Company’s market area. Management has responded by evaluating loans that it considers to carry any significant risk above the normal risk of collectability by taking actions where possible to reduce credit risk exposure by methods that include, but are not limited to, seeking liquidation of the loan by the borrower, seeking additional tangible collateral or other repayment support, converting the property through judicial or non-judicial foreclosure proceedings, and other collection techniques. Management currently believes that it maintains its allowance for loan and lease losses at levels adequate to reflect the loss risk inherent in its total loan portfolio. A continued substantial further decline in the economy in general, or a continued additional decline in real estate values in the Company’s primary market areas, in particular, has had and could continue to have an adverse impact on the collectability of real estate loans and require an increase in the provision for loan and lease losses. This could adversely affect the Company’s future prospects, results of operations, profitability and stock price. Management believes that its lending practices and underwriting standards are structured with the intent to minimize losses; however, there is no assurance that losses will not occur. The Company’s loan practices and underwriting standards include, but are not limited to, the following: (1) maintaining a thorough understanding of the Company’s service area and originating a significant majority of its loans within that area, (2) maintaining a thorough understanding of borrowers’ knowledge, capacity, and market position in their field of expertise, (3) basing real estate loan approvals not only on market demand for the project, but also on the borrowers’ capacity to support the project financially in the event it does not perform to expectations (whether sale or income performance), and (4) maintaining conforming and prudent loan-to-value and loan-to-cost ratios based on independent outside appraisals and ongoing inspection and analysis by the Company’s lending officers or contracted third-party professionals.   35   Nonperforming Loans and Leases Management generally places loans and leases on nonaccrual status when they become 90 days past due or if a loss is expected, unless the loan or lease is well secured and in the process of collection. Loans and leases are partially or fully charged off when, in the opinion of management, collection of such amount appears unlikely. At March 31, 2011, nonperforming loans and leases (those loans and leases on nonaccrual status and those loans and leases still accruing and past due 90 days or more) were $21,595,000 or 6.48% of total loans and leases. The $21,595,000 in nonperforming loans and leases was made up of fifty-four loans and two leases. Eleven of those loans totaling $1,559,000 were current (less than 30 days past due) pursuant to their original or modified terms. Nonperforming loans and leases were $22,571,000 or 6.77% of total loans and leases at December 31, 2010. Of the March 31, 2011 balance, a valuation allowance of $416,000 was established on the nonperforming loans. Of the December 31, 2010 balance, a valuation allowance of $385,000 was established. The overall level of nonperforming loans decreased $976,000 (4.3%) to $21,595,000 at March 31, 2011 compared to $22,571,000 at of December 31, 2010. At December 31, 2010, nonperforming loans were comprised of twenty-nine real estate loans totaling $18,735,000; fifteen commercial loans totaling $3,491,000; seven consumer loans totaling $317,000; and three leases totaling $28,000. During the first quarter of 2011, five of those loans totaling $1,988,000 were moved to OREO, four loans were partially charged off in the amount of $521,000, one loan in the amount of $2,000 was paid off, one loan was completely charged off in the amount of $27,000, one loan in the amount of $49,000 was current and returned to performing status and ten loans in the total amount of $1,666,000 were placed on nonperforming status. The Company also collected approximately $55,000 in principal paydowns. Of the ten loans added in the first quarter, seven in the total amount of $1,305,000 are real estate secured, one in the amount of $95,000 was a commercial loan and two in the amount of $266,000 were consumer loans. Two of these lending relationships were over $250,000. The first consisted of five loans originated to a single borrower for real estate development in Placer and Sacramento Counties. The five loans totaled $588,000. The second relationship was one loan secured by commercial property in Sacramento County in the amount of $473,000. The net interest due on nonaccrual loans and leases but excluded from interest income was $425,000 for the three months ended March 31, 2011, compared to foregone interest of $302,000 during the same period in 2010. There were no loan or lease concentrations in excess of 10% of total loans and leases not otherwise disclosed as a category of loans and leases as of March 31, 2011. Management is not aware of any potential problem loans, which were accruing and current at March 31, 2011, where serious doubt exists as to the ability of the borrower to comply with the present repayment terms and that would result in a significant loss to the Company. Table Seven below sets forth nonaccrual loans and loans past due 90 days or more as of March 31, 2011 and December 31, 2010. Table Seven: Nonperforming Loans and Leases (dollars in thousands) March 31,  December 31,   2011  2010 Past due 90 days or more and still accruing      Commercial $—  $— Real estate  —   — Lease financing receivable  —   — Consumer and other  —   — Nonaccrual        Commercial  3,387   3,491 Real estate  17,650   18,735 Lease financing receivable  25   28 Consumer and other  533   317 Total nonperforming loans $21,595  $22,571    36   Impaired Loans and Leases The Company considers a loan to be impaired when, based on current information and events, it is probable that it will be unable to collect all amounts due (principal and interest) according to the original contractual terms of the loan or lease agreement. The measurement of impairment may be based on (i) the present value of the expected cash flows of the impaired loan or lease discounted at the loan or lease’s original effective interest rate, (ii) the observable market price of the impaired loan or lease, or (iii) the fair value of the collateral of a collateral-dependent loan. The Company does not apply this definition to smaller-balance loans or leases that are collectively evaluated for credit risk. In assessing whether a loan or lease is impaired, the Company typically reviews loans or leases graded substandard or lower with outstanding principal balances in excess of $100,000 as well as loans considered troubled debt restructures with outstanding principal balances in excess of $25,000. At March 31, 2011, the recorded investment in loans and leases that were considered to be impaired totaled $38,550,000, which includes $20,156,000 in performing loans and leases. Of the total impaired loans of $38,550,000, loans totaling $21,699,000 were deemed to require no specific reserve and loans totaling $16,851,000 were deemed to require a related valuation allowance of $1,035,000. Of the $21,699,000 impaired loans that did not carry a specific reserve there were $10,464,000 in loans or leases that had previous partial charge-offs and $11,235,000 in loans or leases that were analyzed and determined not to require a specific reserve or charge-off because the collateral value or discounted cash flow value exceeded the loan or lease balance. The recorded investment in loans and leases that were considered to be impaired totaled $40,237,000 at December 31, 2010. Of the total impaired loans of $40,237,000, loans totaling $22,168,000 were deemed to require no specific reserve and loans totaling $18,069,000 were deemed to require a related valuation allowance of $1,619,000. The Company has been operating in a market that has experienced significant decreases in real estate values of commercial, residential, land, and construction properties. As such, the Company is focused on monitoring collateral values for those loans considered collateral dependent. The collateral evaluations performed by the Company are updated as necessary, which is generally once every six months, and are reviewed by a qualified credit officer. In the first three months of 2011, the Company had a net charge-off of $1,598,000 with a provision of $1,375,000. In the first three months of 2010, the Company had net charge-offs of $1,170,000 with a provision of $1,641,000. At March 31, 2011, there were fourteen loans and leases that were modified and are currently performing (less than ninety days past due) totaling $8,215,000 and thirteen loans and leases that are considered nonperforming (and included in Table Seven above), totaling $6,700,000, that are considered troubled debt restructures (“TDR”). These TDRs have a specific reserve of $187,000. As of March 31, 2011, of the twenty-seven TDRs, there were thirteen extensions, five changes in terms, four rate reductions, three term outs, one interest only structure change and one forbearance. All were performing as agreed except for five extensions, four rate reductions, two changes to amortizing loans, one interest only structure change, and one term out. The Company generally requires TDRs that are on non-accrual status to make six consecutive payments on the restructured loan or lease prior to returning the loan or lease to accrual status. Allowance for Loan and Lease Losses Activity The Company maintains an allowance for loan and lease losses (“ALLL”) to cover probable losses inherent in the loan and lease portfolio, which is based upon management’s estimated range of those losses. The ALLL is established through a provision for loan and lease losses and is increased by provisions charged against current earnings and recoveries and reduced by charge-offs. Actual losses for loans and leases can vary significantly from this estimate. The methodology and assumptions used to calculate the allowance are continually reviewed as to their appropriateness given the most recent losses realized and other factors that influence the estimation process. The model assumptions and resulting allowance level are adjusted accordingly as these factors change. The adequacy of the ALLL and the level of the related provision for loan and lease losses is determined based on management’s judgment after consideration of numerous factors including but not limited to: (i) local and regional economic conditions, (ii) the financial condition of the borrowers, (iii) loan impairment and the related level of expected charge-offs, (iv) evaluation of industry trends, (v) industry and other concentrations, (vi) loans and leases which are contractually current as to payment terms but demonstrate a higher degree of risk as identified by management, (vii) continuing evaluations of the performing loan portfolio, (viii) ongoing review and evaluation of problem loans identified as having loss potential, (ix) quarterly review by the Board of Directors, and (x) assessments by banking regulators and other third parties. Management and the Board of Directors evaluate the ALLL and determine its appropriate level considering objective and subjective measures, such as knowledge of the borrowers’ business, valuation of collateral, the determination of impaired loans or leases and exposure to potential losses.   37   The allowance for loan and lease losses totaled $7,362,000 or 2.21% of total loans and leases at March 31, 2011 compared to $7,585,000 or 2.19% of total loans and leases at December 31, 2010. The Company establishes general and specific reserves in accordance with the generally accepted accounting principles. The ALLL is maintained by categories of the loan and lease portfolio based on loan type and loan rating; however, the entire allowance is available to cover actual loan and lease losses. While management uses available information to recognize possible losses on loans and leases, future additions to the allowance may be necessary, based on changes in economic conditions and other matters. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s ALLL. Such agencies may require the Company to provide additions to the allowance based on their judgment of information available to them at the time of their examination. The allowance for loans and leases as a percentage of non-performing loans and leases was 34.1% at March 31, 2011 and 33.6% at December 31, 2010. The allowance for loans and leases as a percentage of impaired loans and leases was 20.1% at March 31, 2011 and 18.9% at December 31, 2010. Of the total non-performing and impaired loans and leases outstanding as of March 31, 2011, there were $20,088,000 in loans or leases that had been reduced by partial charge-offs of $7,801,000. As these loan or lease balances are charged off, the remaining balances, following analysis, normally do not require specific reserves and are not eligible for general reserves. The impact on credit ratios is such that the Company’s allowance for loan and lease losses as a percentage may be lower, however, the partial charge-offs have reduced the potential future losses related to those credits. The Company’s policy with regard to loan or lease charge-offs continues to be that a loan or lease is charged off against the allowance for loan and lease losses when management believes that the collectability of the principal is unlikely. Generally, a loan or lease is charged off when estimated losses related to impaired loans and leases are identified. If the loan is collateralized by real estate the impaired portion will be charged off to the allowance for loan and lease losses unless it in the process of collection, in which case a specific reserve may be warranted. If the collateral is other than real estate the Company will typically charge-off the impaired portion of a loan, unless it is in the process of collection, in which case a specific reserve may be warranted. It is the policy of management to maintain the allowance for loan and lease losses at a level believed to be adequate for known and inherent risks in the portfolio. Our methodology incorporates a variety of risk considerations, both quantitative and qualitative, in establishing an allowance for loan and lease losses that management believes is appropriate at each reporting date. Based on information currently available to analyze inherent credit risk, including economic factors, overall credit quality, historical delinquencies and a history of actual charge-offs, management believes that the provision for loan and lease losses and the allowance for loan and lease losses are prudent and adequate. Adjustments may be made based on differences from estimated loan and lease growth, the types of loans constituting this growth, changes in risk ratings within the portfolio, and general economic conditions. However, no prediction of the ultimate level of loans and leases charged off in future periods can be made with any certainty.

This compares to 14 properties totaling $2,696,000 at December 31, 2010 and 18 properties totaling $3,271,000 at March 31, 2010. During the first quarter of 2011, the Company sold three properties with balances of $554,000 for a loss of $28,000 and added six properties to OREO with fair values less costs to sell totaling $1,766,000 after writing the related loans down by $222,000 through the allowance for loan losses. Of the six properties added during the quarter was one is a multi-tenant office building in Sacramento County carried for $1,037,000; two properties are single family residences (one in El Dorado County carried for $210,000 and the other in Calaveras County carried for $127,000); two properties are commercial buildings both in Calaveras County (one is a wine storage facility carried at $178,000 and the other is a single tenant lease of a 2,300 square foot retail building carried for $131,000); and one property is 2.1 acres of residential land in Calaveras County carried for $83,000. The Company periodically obtains property valuations to determine whether the recorded book value represents fair value. During the first quarter of 2011, this valuation process resulted in the Company reducing the book value of the OREO properties by $37,000. In addition, the Company received updated appraisals on two properties that were obtained in late 2010 resulting in write downs to the allowance for loan and lease losses of $166,000. At March 31, 2011, the OREO reserve was $63,000. This compares to a reserve balance of zero at March 31, 2010 and $100,000 at December 31, 2010. The Company believes that all 17 OREO properties owned at March 31, 2011 are carried approximately at fair value.   39   Deposits At March 31, 2011, total deposits were $465,908,000 representing a slight increase from the December 31, 2010 balance of $465,122,000. The Company’s deposit growth plan for 2011 is to concentrate its efforts on increasing noninterest-bearing demand, interest-bearing money market and NOW accounts, and savings accounts and allow higher cost time deposits to mature and close. The Company experienced increases in noninterest-bearing ($3,516,000 or 2.8%), interest-bearing checking ($659,000 or 1.5%), money market ($2,952,000 or 2.1%) and savings ($853,000 or 1.9%) accounts and a decrease in time deposits ($7,194,000 or 6.5%) during the first quarter of 2011. Other Borrowed Funds Other borrowings outstanding as of March 31, 2011 and December 31, 2010, consist of advances (both long-term and short-term) from the Federal Home Loan Bank of San Francisco (“FHLB”). Table Nine below summarizes these borrowings. Table Nine: Other Borrowed Funds            (dollars in thousands)              March 31, 2011  December 31, 2010   Amount  Rate  Amount  RateShort-term borrowings:                             FHLB advances $7,000   2.57% $7,000   2.40%                 Long-term borrowings:                                 FHLB advances $5,000   2.73% $10,000   2.41%The maximum amount of short-term borrowings at any month-end during the first quarters of 2011 and 2010 was $12,000,000 and $9,500,000, respectively. The FHLB advances are collateralized by loans and securities pledged to the FHLB. The following is a breakdown of rates and maturities on FHLB advances (dollars in thousands):   Short-term  Long-term Amount $7,000  $5,000 Maturity2011 to 2012  2012 to 2014 Average rates  2.57%  2.73%The Company has also been issued a total of $10,000,000 in letters of credit by the FHLB which are pledged to secure Local Agency Deposits. The letters of credit act as a guarantee of payment to certain third parties in accordance with specified terms and conditions. The letters of credit were not drawn upon in 2011 or 2010 and management does not currently expect to draw upon these lines in the foreseeable future. See the Liquidity section that follows for additional information on FHLB borrowings. Capital Resources The Company and American River Bank are subject to certain regulatory capital requirements administered by the Federal Reserve Board and the Federal Deposit Insurance Corporation (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 and the regulatory framework for prompt corrective action, banks 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. The Company’s and American River Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. As a result of a 2009 FDIC examination, management entered into a Memorandum of Understanding as of February 10, 2010 with the FDIC and the California Commissioner of Financial Institutions, which requires the Bank to take certain actions including maintaining the Bank’s Tier I Leverage capital ratio at not less than 8% and a Total Risk-Based capital ratio of not less than 11%. As of March 31, 2011, the foregoing capital ratios for the Bank were 12.0% and 19.8%, respectively. We believe that we are currently in compliance in all material respects with the actions described in the Memorandum, including the capital ratios as described above. See “Note 13, OTHER MATTERS” herein for more information regarding the Memorandum.   40   At March 31, 2011, shareholders’ equity was $89,950,000, representing an increase of $406,000 (0.5%) from $89,544,000 at December 31, 2010. The increase results from net income for the period, the stock based compensation, and the increase in other comprehensive income. The ratio of total risk-based capital to risk adjusted assets was 21.0% at March 31, 2011 and 20.3% at December 31, 2010. Tier 1 risk-based capital to risk-adjusted assets was 19.8% at March 31, 2011 and 19.1% at December 31, 2010. The leverage ratio was 12.8% at March 31, 2011 and 12.6% at December 31, 2010. Table Ten below lists the Company’s actual capital ratios at March 31, 2011 and December 31, 2010 as well as the minimum capital ratios for capital adequacy. Table Ten: Capital Ratios     Capital to Risk-Adjusted Assets At March 31, 2011 At December 31, 2010 Minimum Regulatory Capital Requirements          Leverage ratio 12.8% 12.6% 4.00%          Tier 1 Risk-Based Capital 19.8% 19.1% 4.00%          Total Risk-Based Capital 21.0% 20.3% 8.00% Capital ratios are reviewed on a regular basis to ensure that capital exceeds the prescribed regulatory requirements and is adequate to meet future needs. Management believes that both the Company and American River Bank met all of their capital adequacy requirements as of March 31, 2011 and December 31, 2010. On December 17, 2009, the Company filed a Current Report with the SEC on Form 8-K announcing the completion of an offering of approximately $24 million of its common stock. Effective July 27, 2009, the Company temporarily suspended both the payment of cash dividends and stock repurchases. See Part II, Item 2, for additional disclosure regarding the stock repurchase plan. Inflation The impact of inflation on a financial institution differs significantly from that exerted on manufacturing or other commercial concerns primarily because its assets and liabilities are largely monetary. In general, inflation primarily affects the Company and it subsidiaries through its effect on market rates of interest, which affects the Company’s ability to attract loan customers. Inflation affects the growth of total assets by increasing the level of loan demand and potentially adversely affects capital adequacy because loan growth in inflationary periods can increase at rates higher than the rate that capital grows through retention of earnings which may be generated in the future. In addition to its effects on interest rates, inflation increases overall operating expenses. Inflation has not had a significant effect upon the results of operations of the Company and its subsidiaries during the periods ended March 31, 2011 and 2010. Liquidity Liquidity management refers to the Company’s ability to provide funds on an ongoing basis to meet fluctuations in deposit levels as well as the credit needs and requirements of its clients. Both assets and liabilities contribute to the Company’s liquidity position. Federal funds lines, short-term investments and securities, and loan and lease repayments contribute to liquidity, along with deposit increases, while loan and lease funding and deposit withdrawals decrease liquidity. The Company assesses the likelihood of projected funding requirements by reviewing historical funding patterns, current and forecasted economic conditions and individual client funding needs. Commitments to fund loans and outstanding standby letters of credit at March 31, 2011 were approximately $41,419,000 and $10,121,000, respectively. Such loan commitments relate primarily to revolving lines of credit and other commercial loans and to real estate construction loans. Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.   41   The Company’s sources of liquidity consist of cash and due from correspondent banks, overnight funds sold to correspondent banks, unpledged marketable investments and loans held for sale and/or pledged for secured borrowings. At March 31, 2011, consolidated liquid assets totaled $137.4 million or 24.0% of total assets compared to $128.1 million or 22.1% of total assets on December 31, 2010. In addition to liquid assets, the Company maintains two short-term unsecured lines of credit in the amount of $20,000,000 with two of its correspondent banks. At March 31, 2011, the Company had $20,000,000 available under these credit lines. Additionally, the Bank is a member of the FHLB. At March 31, 2011, the Bank could have arranged for up to $92,058,000 in secured borrowings from the FHLB. These borrowings are secured by pledged mortgage loans and investment securities. At March 31, 2011, the Company had advances, borrowings and commitments (including letters of credit) outstanding of $22,000,000, leaving $70,058,000 available under these FHLB secured borrowing arrangements. American River Bank also has a secured borrowing arrangement with the Federal Reserve Bank of San Francisco. The borrowing can be secured by pledging selected loans and investment securities. At March 31, 2011, the Company’s borrowing capacity at the Federal Reserve Bank was $27,842,000. The Company serves primarily a business and professional customer base and, as such, its deposit base is susceptible to economic fluctuations. Accordingly, management strives to maintain a balanced position of liquid assets and borrowing capacity to offset the potential runoff of these volatile and/or cyclical deposits. Liquidity is also affected by portfolio maturities and the effect of interest rate fluctuations on the marketability of both assets and liabilities. The Company can sell any of its unpledged securities held in the available-for-sale category to meet liquidity needs. The Bank has established a master repurchase agreement with a correspondent bank to enable such transactions. Futhermore, the Bank can pledge additional unencumbered securities to borrow from the Federal Reserve Bank of San Francisco and the FHLB. Off-Balance Sheet Items 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 letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized on the balance sheet. The Company’s exposure to credit loss in the event of nonperformance by the other party for commitments to extend credit and letters of credit is represented by the contractual amount of those instruments. The Company applies the same credit policies to commitments and letters of credit as it does for loans included on the consolidated balance sheet. As of March 31, 2011 and December 31, 2010, commitments to extend credit and standby letters of credit were the only financial instruments with off-balance sheet risk. The Company has not entered into any contracts for financial derivative instruments such as futures, swaps, options or similar instruments. Loan commitments and standby letters of credit were $51,540,000 and $52,481,000 at March 31, 2011 and December 31, 2010, respectively. As a percentage of net loans and leases these off-balance sheet items represent 15.8% and 15.5%, respectively. The Company has certain ongoing commitments under operating leases. These commitments do not significantly impact operating results. Website Access American River Bankshares maintains a website where certain information about the Company is posted.

Quantitative and Qualitative Disclosures About Market Risk. Market Risk Management Overview. Market risk is the risk of loss from adverse changes in market prices and rates. The Company’s market risk arises primarily from interest rate risk inherent in its loan, investment and deposit functions. The goal for managing the assets and liabilities of the Company is to maximize shareholder value and earnings while maintaining a high quality balance sheet without exposing the Company to undue interest rate risk. The Board of Directors has overall responsibility for the interest rate risk management policies. The Company has a Risk Management Committee, made up of Company management that establishes and monitors guidelines to control the sensitivity of earnings to changes in interest rates. Asset/Liability Management. Activities involved in asset/liability management include but are not limited to lending, accepting and placing deposits and investing in securities. Interest rate risk is the primary market risk associated with asset/liability management. Sensitivity of earnings to interest rate changes arises when yields on assets change in a different time period or in a different amount from that of interest costs on liabilities. To mitigate interest rate risk, the structure of the balance sheet is managed with the goal that movements of interest rates on assets and liabilities are correlated and contribute to earnings even in periods of volatile interest rates. The asset/liability management policy sets limits on the acceptable amount of variance in net interest margin and market value of equity under changing interest environments. The Company uses simulation models to forecast earnings, net interest margin and market value of equity. Simulation of earnings is the primary tool used to measure the sensitivity of earnings to interest rate changes. Using computer-modeling techniques, the Company is able to estimate the potential impact of changing interest rates on earnings. A balance sheet forecast is prepared quarterly using inputs of actual loans, securities and interest-bearing liabilities (i.e. deposits/borrowings) positions as the beginning base. The forecast balance sheet is processed against three interest rate scenarios. The scenarios include a 200 basis point rising rate forecast, a flat rate forecast and a 200 basis point falling rate forecast which take place within a one-year time frame. The net interest income is measured during the year assuming a gradual change in rates over the twelve-month horizon. The simulation modeling indicated below attempts to estimate changes in the Company’s net interest income utilizing a forecast balance sheet projected from the end of period balances. Table Eleven below summarizes the effect on net interest income (NII) of a ±200 basis point change in interest rates as measured against a constant rate (no change) scenario. Table Eleven: Interest Rate Risk Simulation of Net Interest as of March 31, 2011 and December 31, 2010(dollars in thousands)  $ Change in NIIfrom Current12 Month HorizonMarch 31, 2011  $ Change in NIIfrom Current12 Month HorizonDecember 31, 2010 Variation from a constant rate scenario            +200bp  $37  $289      - 200bp  $ (1,380)  $  (1,739)  Management does not consider the fluctuations, as outlined in the table above, to have a material impact on the Company’s projected results and are within the tolerance levels outlined in the Company’s interest rate risk polices. The simulations of earnings do not incorporate any management actions, which might moderate the negative consequences of interest rate deviations. Therefore, they do not reflect likely actual results, but serve as reasonable estimates of interest rate risk.   43   Item 4. Controls and Procedures. The Company, under the supervision and with the participation of its management, including the Chief Executive Officer and the Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s “disclosure controls and procedures” (as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of March 31, 2011. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective in timely making known to them material information relating to the Company and the Company’s consolidated subsidiaries required to be disclosed in the Company’s reports filed or submitted under the Exchange Act. During the quarter ended March 31, 2011, there have been no changes in the Company’s internal control over financial reporting that have significantly affected, or are reasonably likely to materially affect, these controls. PART II – OTHER INFORMATION Item 1. Legal Proceedings. From time to time, the Company and/or its subsidiaries is a party to claims and legal proceedings arising in the ordinary course of business. The Company’s management is not aware of any significant pending legal proceedings to which either it or its subsidiaries may be a party or has recently been a party, which will have a significant adverse effect on the financial condition or results of operations of the Company or its subsidiaries, taken as a whole. Item 1A. Risk Factors. There have been no significant changes in the risk factors previously disclosed in the Company’s Form 10-K for the period ended December 31, 2010, filed with the Securities and Exchange Commission on March 4, 2011. Item 2. Unregistered Sales of Equity Securities and Use of Proceeds. On January 16, 2008, the Board of Directors of the Company authorized a stock repurchase program which allows for the repurchase of up to six and one half percent (6.5%) annually of the Company’s outstanding shares of common stock. On July 27, 2009, the Company announced that the Board of Directors was temporarily suspending the stock repurchase program, therefore the number of shares reported in column (d) of the table as shares that may be repurchased under the plan are zero for the periods stated. The Company relies on distributions from the Bank in the form of cash dividends in order to fund its repurchase program. As a result of a regularly scheduled FDIC examination in 2009, the Bank entered into a Memorandum of Understanding in February 2010 with the FDIC and the California Commissioner of Financial Institutions which requires the Bank to take certain actions including restricting the payment of cash dividends. As a result, any future cash dividends from the Bank will require prior approval from its regulators. The following table lists shares repurchased during the quarter ended March 31, 2011 and the maximum amount available to repurchase under the repurchase plan, which as a result on the suspension of the repurchase program was zero.
