FNB Bancorp (Bulletin Board: FNBG), parent company of First National Bank of Northern California (the “Bank”), today announced net earnings available to common shareholders for the first quarter of 2011 of $589,000 or $0.18 per diluted share, compared to net earnings available to common shareholders of $792,000 or $0.24 per diluted share for the first quarter of 2010. Dividend payments on the preferred shares outstanding were made as required by the Treasury Department’s Capital Purchase Program during the quarters ended March 31, 2011 and 2010. The Bank’s balance sheet is highly liquid, the allowance for loan and lease losses is an adequate measurement of risk in the Bank's loan portfolio and the Bank continues to be “well capitalized” as defined by bank regulations. Total assets as of March 31, 2011 were $696,590,000 compared to $723,566,000 as of March 31, 2010. Our net loans decreased by $22,119,000 or 4.5% year over year and our deposits decreased by $14,096,000 or 2.3% during the same period. At March 31, 2011, the Company has considerable liquid assets on hand as evidenced by $131,861,000 in available for sale securities and $49,326,000 in cash and due from banks.

During April 2011, the Bank opened our newest branch, located in the Marina District of San Francisco, at 2197 Chestnut Street. The Chestnut Street branch is expected to be a strong source of new loan and deposit production. The initial reception from the local community has been very positive.

“In the current economic environment in which we operate, investable dollars are plentiful, but loan demand remains muted. Our local economy, outside of real estate activity, appears to be slowly improving. The recovery is coming, or so it seems, but it appears to be a weak recovery that has and will require, for better or worse, a significant amount of federal support. In the current environment, many potential borrowers are finding that obtaining a mortgage loan is exceedingly difficult. We are looking to expand the funding of single family mortgage loans in our marketplace, and we hopefully can take some of the mystery and guesswork out of the loan origination process. We are a true community bank in every sense of the word. We intend to keep the loans we originate in our own loan portfolio, and the opening of the Chestnut Street branch should help us to increase our production of deposits and single family mortgage loans and lines of credit,” stated Tom McGraw, Chief Executive Officer.

“During the first quarter of 2011, the Bank was able to increase our loan loss reserves as the size of our loan portfolio and our asset base decreased. Our Bank is in the business of bringing in local deposits and lending out funds to qualified borrowers in our marketplace. We continue to manage our asset portfolios in order to insure that risk levels contained within these portfolios are maintained at prudent levels. We are also seeking out new deposit and loan relationships, as evidenced by the opening of our Chestnut Street branch. Much of management’s attention in the recent past has been focused on risk management issues that exist within our asset portfolios and in improving asset quality to more historic levels. During the first quarter of 2011, profitability levels were still not where we would like them to be; however, the Bank’s net interest margin has remained higher than our peers. We have the capital, liquidity, and management ability to take advantage of market opportunities as they become available. It is our intent to continue to seek out growth opportunities, with the understanding that the strength of our institution is derived from our ability to grow the Bank through the increase of our deposit and loan relationships that are generated from our local marketplace,” continued Tom McGraw.
