GENERAL	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. In addition to its branch network, the Bank operates an 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. The Bank’s deposits are insured by the Federal Deposit Insurance Corporation (FDIC) up to applicable legal limits. The Bank participated in the Federal Deposit Insurance Corporation (FDIC) Transaction Account Guarantee Program. Under the program, through December 31, 2010, all noninterest-bearing transaction accounts were fully guaranteed by the FDIC for the entire amount in the account. 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. Amendments related to the enactment of the Dodd-Frank Act now provide full deposit insurance coverage for noninterest bearing deposit transaction accounts beginning December 31, 2010 for an additional two year period.
