1. GENERAL

During 2002, Plumas Bancorp (the “Company”) was incorporated as a bank holding company for the purpose of acquiring Plumas Bank (the “Bank”) in a one bank holding company reorganization. This corporate structure gives the Company and the Bank greater flexibility in terms of operation expansion and diversification. The Company formed Plumas Statutory Trust I (“Trust I”) for the sole purpose of issuing trust preferred securities on September 26, 2002. The Company formed Plumas Statutory Trust II (“Trust II”) for the sole purpose of issuing trust preferred securities on September 28, 2005.

The Bank operates eleven branches in California, including branches in Alturas, Chester, Fall River Mills, Greenville, Kings Beach, Portola, Quincy, Redding, Susanville, Tahoe City, and Truckee. The Bank’s administrative headquarters is in Quincy, California. In addition, the Bank operates a loan administrative office in Reno, Nevada and a lending office specializing in government-guaranteed lending in Auburn, California. The Bank’s primary source of revenue is generated from providing loans to customers who are predominately small and middle market businesses and individuals residing in the surrounding areas.

On July 21, 2010, President Barack Obama signed the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), which, in part, permanently raised the current standard maximum deposit insurance amount to $250,000. In addition, amendments to the Dodd-Frank Act extended unlimited FDIC insurance coverage for noninterest-bearing transaction deposit accounts for an additional two years. This unlimited insurance coverage for noninterest-bearing transaction accounts expired on December 31, 2012.

2. REGULATORY MATTERS

On February 15, 2012, the Bank received notice from the Federal Deposit Insurance Corporation (FDIC) and the California Department of Financial Institutions (“DFI”) that the Consent Order with the FDIC and the DFI which was effective on March 16, 2011 had been terminated. While the Bank is no longer subject to an Order, the Bank entered into an informal agreement with the FDIC and DFI which, among other things, requests that the Bank continue to maintain a Tier 1 Leverage Capital Ratio of 9% which is in excess of that required for well capitalized institutions and continue to reduce its level of classified asset balances that were outstanding as of September 30, 2011 to not more than 50% of Tier 1 Capital plus the allowance for loan losses. At December 31, 2012 this ratio was 32% and the Bank’s Tier 1 Leverage Capital Ratio was 10.4%. The FDIC and DFI terminated the informal agreement effective January 24, 2013.

On July 28, 2011 the Company entered into an agreement with the Federal Reserve Bank of San Francisco (the “FRB Agreement”). Under the terms of the FRB Agreement, Plumas Bancorp has agreed to take certain actions that are designed to maintain its financial soundness so that it may continue to serve as a source of strength to the Bank. Among other things, the FRB Agreement requires prior written approval related to the payment or taking of dividends and distributions, making any distributions of interest, principal or other sums on subordinated debentures or trust preferred securities, incurrence of debt, and the purchase or redemption of stock. In March 2013 the FRB allowed Plumas Bancorp to pay all past due and current interest on its trust preferred securities. As of March 31, 2013 the amount of the arrearage on the dividend payments of the Series A Preferred Stock is $1.8 million representing twelve quarterly payments.

On April 19, 2013 the Company received notice that the FRB Agreement had been terminated.

3. CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The condensed consolidated financial statements include the accounts of the Company and the accounts of its wholly-owned subsidiary, Plumas Bank. Plumas Statutory Trust I and Plumas Statutory Trust II are not consolidated into the Company’s consolidated financial statements and, accordingly, are accounted for under the equity method. In the opinion of management, the unaudited condensed consolidated financial statements contain all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the Company’s financial position at March 31, 2013 and the results of its operations and its cash flows for the three-month periods ended March 31, 2013 and 2012. Our condensed consolidated balance sheet at December 31, 2012 is derived from audited financial statements. Certain reclassifications have been made to prior period’s balances to conform to classifications used in 2013.

The unaudited condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim reporting on Form 10-Q. Accordingly, 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 (“GAAP”) have been omitted. The Company believes that the disclosures are adequate to make the information not misleading. These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2012 Annual Report to Shareholders on Form 10-K. The results of operations for the three-month period ended March 31, 2013 may not necessarily be indicative of future operating results. 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 periods reported. Actual results could differ significantly from those estimates.

Management has determined that because all of the commercial banking products and services offered by the Company are available in each branch of the Bank, all branches are located within the same economic environment and management does not allocate resources based on the performance of different lending or transaction activities, it is appropriate to aggregate the Bank branches and report them as a single operating segment. No single customer accounts for more than 10% of the revenues of the Company or the Bank.

4. INVESTMENT SECURITIES AVAILABLE FOR SALE

The amortized cost and estimated fair value of investment securities at March 31, 2013 and December 31, 2012 consisted of the following:

Unrealized gains on available-for-sale investment securities totaling $274,000 were recorded, net of $113,000 in tax expense, as accumulated other comprehensive income within shareholders’ equity at March 31, 2013. During the three months ended March 31, 2012, the Company sold three available-for-sale securities for total proceeds of $4,471,000, which resulted in the recognition of a $51,000 gross gain on sale. No securities were sold during the three months ended March 31, 2013.

Net unrealized gains on available-for-sale investment securities totaling $561,000 were recorded, net of $232,000 in tax expense, as accumulated other comprehensive income within shareholders’ equity at December 31, 2012. During the year ended December 31, 2012, the Company sold twenty-five available-for-sale investment securities for $20,773,000, recording a $403,000 gain on sale. No securities were sold at a loss.

Investment securities with unrealized losses at March 31, 2013 are summarized and classified according to the duration of the loss period as follows:

Investment securities with unrealized losses at December 31, 2012 are summarized and classified according to the duration of the loss period as follows:

There were no securities in a loss position for more than one year as of March 31, 2013 and December 31, 2012.

At March 31, 2013, the Company held 57 securities of which 16 were in a loss position. Of the securities in a loss position, all were in a loss position for less than twelve months. Of the 16 securities, 1 is a U.S. Government-sponsored agencies and 15 are U.S. Government-sponsored agencies collateralized by mortgage obligations. The unrealized losses primarily relate to changes in interest rates and other market conditions. All of the securities continue to pay as scheduled. When analyzing an issuer’s financial condition, management considers the length of time and extent to which the market value has been less than cost; the historical and implied volatility of the security; the financial condition of the issuer of the security; and the Company’s intent and ability to hold the security to recovery. As of March 31, 2013, management does not have the intent to sell these securities nor does it believe it is more likely than not that it will be required to sell these securities before the recovery of its amortized cost basis. Based on the Company’s evaluation of the above and other relevant factors, the Company does not believe the securities that are in an unrealized loss position as of March 31, 2013 are other than temporarily impaired.

The amortized cost and estimated fair value of investment securities at March 31, 2013 by contractual maturity are shown below. 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.

Investment securities with amortized costs totaling $47,300,000 and $44,305,000 and estimated fair values totaling $47,542,000 and $44,535,000 at March 31, 2013 and December 31, 2012, respectively, were pledged to secure deposits and repurchase agreements.

5. LOANS AND THE ALLOWANCE FOR LOAN LOSSES

Outstanding loans are summarized below, in thousands:

The recorded investment in impaired loans totaled $16,864,000 and $18,850,000 at March 31, 2013 and December 31, 2012. The Company had specific allowances for loan losses of $1,371,000 on impaired loans of $7,213,000 at March 31, 2013 as compared to specific allowances for loan losses of $1,186,000 on impaired loans of $14,334,000 at December 31, 2012. The balance of impaired loans in which no specific reserves were required totaled $9,651,000 and $4,516,000 at March 31, 2013 and December 31, 2012, respectively. The average recorded investment in impaired loans for the three months ended March 31, 2013 and March 31, 2012 was $17,440,000 and $23,944,000, respectively. The Company recognized $103,000 and $127,000 in interest income on a cash basis for impaired loans during the three months ended March 31, 2013 and 2012, respectively.

Included in impaired loans are troubled debt restructurings. A troubled debt restructuring is a formal restructure of a loan where the Company for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower. The concessions may be granted in various forms, one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a permanent reduction of the recorded investment in the loan.

The carrying value of troubled debt restructurings at March 31, 2013 and December 31, 2012 was $12,149,000 and $12,296,000, respectively. The Company has allocated $985,000 and $348,000 of specific reserves on loans to customers whose loan terms have been modified in troubled debt restructurings as of March 31, 2013 and December 31, 2011, respectively. The Company was not committed to lend additional amounts on loans classified as troubled debt restructurings at March 31, 2013 and December 31, 2012.

During the three month period ended March 31, 2013 and December 31, 2012, the terms of certain loans were modified as troubled debt restructurings. Modifications involving a reduction of the stated interest rate of the loan was for periods ranging from 1 month to 10 years. For the periods described above, modifications involving an extension of the maturity date were for periods ranging from 1 month to 10 years.

The following table presents loans by class modified as troubled debt restructurings that occurred during the three months ending March 31, 2013:

The troubled debt restructuring described above resulted in no allowance for loan losses or charge-offs during the three months ending March 31, 2013.

The following table presents loans by class modified as troubled debt restructurings for which there was a payment default within twelve months following the modification during the three months ended March 31, 2013.

The following table presents loans by class modified as troubled debt restructurings that occurred during the twelve months ending December 31, 2012:

The troubled debt restructurings described above decreased the allowance for loan losses by $118,000 during the twelve months ending December 31, 2012. The troubled debt restructurings described above did not result in charge offs during the twelve months ending December 31, 2012.

The following table presents loans by class modified as troubled debt restructurings for which there was a payment default within twelve months following the modification during the twelve months ended December 31, 2012.

The terms of certain other loans were modified during the three months ending March 31, 2013 and year ending December 31, 2012 that did not meet the definition of a troubled debt restructuring. These loans have a total recorded investment as of March 31, 2013 and December 31, 2012 of $874 thousand and $9 million, respectively.

These loans which were modified during the three month ended March 31, 2013 and year ended December 31, 2012 did not meet the definition of a troubled debt restructuring as the modification was a delay in a payment ranging from 30 days to 3 months that was considered to be insignificant or the borrower was not considered to be experiencing financial difficulties.

At March 31, 2013 and December 31, 2012, nonaccrual loans totaled $12,974,000 and $13,683,000, respectively. Interest foregone on nonaccrual loans totaled $180,000 and $200,000 for the three months ended March 31, 2013 and 2012, respectively. Loans past due 90 days or more and on accrual status totaled $1,258,000 and $15,000 at March 31, 2013 and December 31, 2012.

11

Salaries and employee benefits totaling $294,000 and $195,000 have been deferred as loan origination costs during the three months ended March 31, 2013 and 2012, respectively.

The Company assigns a risk rating to all loans and periodically, but not less than annually, performs detailed reviews of all such loans over $100,000 to identify credit risks and to assess the overall collectability of the portfolio. These risk ratings are also subject to examination by independent specialists engaged by the Company and the Company’s regulators. During these internal reviews, management monitors and analyzes the financial condition of borrowers and guarantors, trends in the industries in which borrowers operate and the fair values of collateral securing these loans. These credit quality indicators are used to assign a risk rating to each individual loan.

The risk ratings can be grouped into five major categories, defined as follows:

Pass – A pass loan is a strong credit with no existing or known potential weaknesses deserving of management’s close attention.

Watch – A Watch loan has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the Company’s credit position at some future date. Watch loans are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.

Substandard – A substandard loan is not adequately protected by the current sound worth and paying capacity of the borrower or the value of the collateral pledged, if any. Loans classified as substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Well defined weaknesses include a project’s lack of marketability, inadequate cash flow or collateral support, failure to complete construction on time or the project’s failure to fulfill economic expectations. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

Doubtful – Loans classified doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions and values, highly questionable and improbable.

Loss – Loans classified as loss are considered uncollectible and charged off immediately.
