Andrew J. Ryback, interim president and chief executive officer, remarked:

“The Board of Directors and executive management team are pleased to announce that the Company achieved profitability for the fourth consecutive quarter despite continuing economic challenges. While not satisfied with our earnings, we have stabilized our operating performance with reduced credit losses, a continued focus on cost controls, growth in our government guaranteed lending operations and additional items of non-interest income.”

“Plumas Bancorp’s and Plumas Bank’s capital ratios have improved significantly compared to year end 2009,” continued Ryback. “During 2010, the Bank’s tier 1 leverage, tier 1 risk-based and total risk-based capital ratios grew by 150 basis points, 300 basis points and 300 basis points, respectively and ended the year at 8.9%, 12.8% and 14.0%, respectively. Furthermore, our strong liquidity position provides us with the flexibility to mitigate considerable fluctuations in our funding needs.” He added, “Our top priority is ensuring that our credit risk is proactively managed. Because of that, we’ve restructured our credit administration function and dedicated our highest level loan administrator to the task of accelerating the reduction in problem assets and mitigating losses. This action step, along with a continued strong focus on cost control and revenue growth will position the Company for a higher level of profitability in future periods.”

“We continue to meet the challenges presented by a very stressed economy and are confident that we are well positioned to deal successfully with any future challenges,” concluded Ryback.

Chairman of the Board, Daniel E. West, added, “Last December Plumas Bank celebrated a significant milestone — our 30^th Anniversary. It has been both a privilege and a pleasure to have served our customers for three decades and we look forward to many more years of meeting the financial needs of our local communities. Finally, we would like to take this opportunity to acknowledge our shareholders for their continued confidence in our Company and to thank them for their patience as we continue to work toward a higher level of financial strength and stability.”

Asset Quality

Nonperforming loans at December 31, 2010 were $25.4 million, an increase of $11.1 million over the $14.3 million balance at December 31, 2009. Nonperforming loans as a percentage of total loans increased to 8.07% at December 31, 2010 up from 4.30% at December 31, 2009. The increase in nonperforming loans mostly relates to two large relationships totaling $8 million. These loans were measured for impairment and it was determined that a $0.6 million allowance for impairment was required at December 31, 2010.

Nonperforming assets (which are comprised of nonperforming loans, other real estate owned and repossessed vehicle holdings) at December 31, 2010 were $34.2 million, an increase of $8.6 million over the $25.6 million balance at December 31, 2009.

Repossessed vehicles and OREO (other real estate owned) are carried at the lesser of cost or fair market value, less selling costs. OREO holdings represented thirty-one properties totaling $8.9 million at December 31, 2010 and twenty-nine properties totaling $11.2 million at December 31, 2009. Nonperforming assets as a percentage of total assets increased to 7.07% at December 31, 2010 up from 4.84% at December 31, 2009.

During the year ended December 31, 2010 we recorded a provision for loan losses of $5.5 million down $9.0 million from the $14.5 million provision recorded during the year ended December 31, 2009. The Company recorded a $1.8 million provision for loan losses for the three months ended December 31, 2010 compared to the $3.2 million in provision for loan losses for the three months ended December 31, 2009.

Net charge-offs totaled $7.7 million during the year ended December 31, 2010 and $12.2 million during the same period in 2009. Net charge-offs as a percentage of average loans decreased from 3.43% during the year ended December 31, 2009 to 2.39% during the current period. While we incurred significant charge-offs during the 2010 period, $3.1 million of the charge-offs had been incorporated in the allowance for loan losses at December 31, 2009 as specific reserves on impaired loans. The allowance for loan losses totaled $7.3 million at December 31, 2010 and $9.6 million at December 31, 2009. The decrease in the allowance for loan losses from December 31, 2009 is attributable to a $2.4 million decrease in specific reserves related to impaired loans from $4.3 million at December 31, 2009 to $1.9 million at December 31, 2010. General reserves increased by $133 thousand to $5.4 million at December 31, 2010. As a percentage of total loans general reserves were 1.73% at December 31, 2010 and 1.59% at December 31, 2009. Overall, the allowance for loan losses as a percentage of total loans decreased from 2.88% at December 31, 2009 to 2.33% at December 31, 2010, driven by the decline in specific reserves on impaired loans.

“The increase in nonperforming loans resulted from changes in the quality of two large real estate loan relationships that we have been monitoring actively for some time. We are encouraged that, despite the increase in nonperforming loans, the losses associated with such loans were nominal and we are seeing some stabilization of real estate prices in our markets. While far from robust, we are not seeing the declines in appraised values that we saw in the last two years and we are optimistic that this trend will continue in 2011,” stated Ryback.

Cash, Borrowings, Loans and Deposits

On-balance sheet liquidity has improved since December 31, 2009 with increases in cash and due from banks and decreases in borrowings. Cash and due from banks increased by $5.1 million from $59.5 million at December 31, 2009 to $64.6 million at December 31, 2010. Borrowings at the Federal Home Loan Bank (FHLB) totaled $40 million at December 31, 2009, while no borrowings with the FHLB were outstanding at December 31, 2010. Somewhat offsetting these items were a decrease in investments securities of $24.9 million.

Net loans decreased by $16 million, or 5.0% from $323 million at December 31, 2009 to $307 million at December 31, 2010. This decline in net loans was mostly related to normal pay downs and prepayments and loan charge-offs. Deposits decreased by $8 million from $433 million at December 31, 2009 to $425 million at December 31, 2010 mostly related to a decline in our public agency NOW accounts as we significantly lowered the rate paid on these municipal accounts in 2010.

Shareholders’ Equity

Total shareholders’ equity decreased by $243 thousand from $38.2 million at December 31, 2009 to $38.0 million at December 31, 2010. This decrease relates to a $674 thousand decline in unrealized gains on available-for-sale investment securities from $622 thousand at December 31, 2009 to an unrealized loss of $52 thousand at December 31, 2010.

Book value per common share decreased slightly to $5.51 at December 31, 2010 from $5.58 at December 31, 2009. Plumas Bancorp’s total risk-based capital ratio increased from 11.6% at December 31, 2009 to 13.9% at December 31, 2010 and its leverage capital ratio increased from 7.9% at December 31, 2009 to 8.9% at December 31, 2010.

Net Interest Income and Net Interest Margin

Net interest income for the year ended December 31, 2010 was $17.5 million, a decline of $1.7 million from the $19.2 million earned during the same period in 2009. The largest components of the decrease in net interest income was a decline in the average balance of loans and an increase in interest foregone on nonaccrual loans. Other significant changes, resulting in a decrease in net interest income, included a decline in yield on the Company’s investment portfolio and an increase in the average balance of deposits. These items were partially offset by declines in rates paid on deposit and subordinated debentures and an increase in the average balance of investment securities and other interest earning assets. Net interest margin for the year ended December 31, 2010 decreased 27 basis points, or 6%, to 4.25%, down from 4.52% for the same period in 2009.

Net interest income was $4.3 million for the three months ended December 31, 2010, a decrease of $502 thousand, or 10%, from $4.8 million for the same period in 2009. The decline in net interest income was primarily related to a decrease in the average balance and yield on loans and investments. The effect of these items on net interest income was partially offset by a decline in the rates paid on deposit and a decline in average balance and yield on FHLB borrowings. Net interest margin for the three months ended December 31, 2010 decreased 24 basis points to 4.10%, down from 4.34% for the same period in 2009.

Non-Interest Income and Expense

During the year ended December 31, 2010 non-interest income increased by $2.8 million to $8.6 million, from $5.8 million during the year ended December 31, 2009. This increase was primarily related to three items, the largest of which was a $1.4 million gain on the sale of our merchant processing portfolio. During June 2010 we entered into an alliance with a world-wide merchant processing leader. In conjunction with this alliance we sold our merchant processing business, recording a one-time gain of $1.4 million. The Company believes that this alliance provides our customers with a superior merchant processing solution. Additionally we sold $40.9 million in securities recording a gain on sale of $1.2 million. Finally, we recorded a gain on sale of SBA loans of $1.1 million representing the sale of $13.6 million in loans. During the three months ended December 31, 2010, total non-interest income increased by $309 thousand from the same period in 2009. This primarily relates to a $380 thousand gain on the sale of $18.9 million in securities during the 2010 quarter.

During the year ended December 31, 2010, total non-interest expense decreased by $7.1 million, or 27%, to $19.2 million, down from $26.3 million for the comparable period in 2009. The largest component of this decline was a $4.4 million decrease in the provision for OREO losses from $4.8 million during 2009 to $0.4 million during the current year. We also were able to achieve significant reductions in most other categories of expense including declines in salaries and employee benefits ($1.3 million), occupancy and equipment costs ($663 thousand), professional fees ($202 thousand) and losses/gains on the sale of OREO ($201 thousand). These items were partially offset by increases in outside service fees ($222 thousand) and OREO carrying costs ($203 thousand).

Salaries and employee benefits decreased by $1.3 million primarily related to four items. Salary expense, excluding commissions, declined by $796 thousand related to reduced staffing in all areas with the exception of government guaranteed lending and problem assets. While the Company has effectively reduced personnel in most functional areas, we have increased staffing in our problem asset department to effectively manage our increased level of nonperforming assets. Decreases in other employee benefits include reductions in stock compensation expense, the elimination of bonuses for 2010 and, effective April 1, 2010, the discontinuation of the Company’s 401k matching contributions. The reduction in occupancy and equipment expense primarily relates to cost savings at our Redding branch as a result of the purchase of this facility on March 31, 2010.

Losses on the sale of OREO totaled $158 thousand during 2009; however, during 2010 we recorded net gains on sale of OREO totaling $43 thousand.

The increase in outside service fees was primarily related to the outsourcing of daily management of our computer network operations, while the increase in OREO carrying costs is primarily related to the increase in average OREO balances.

During the three months ended December 31, 2010, total non-interest expense decreased by $4.9 million, or 52%, to $4.4 million, down from $9.3 million for the comparable period in 2009. The decrease in non-interest expense was primarily the result of decreases of $3.9 million in the provision for OREO losses. In addition, salaries and employee benefits decreased by $274 thousand and occupancy and equipment expense declined by $154 thousand.
