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 third quarter of 2013 of $2,880,000 or $0.75 per diluted share, compared to net earnings available to common shareholders of $4,783,000 or $1.27 per diluted share for the third quarter of 2012. Dividend payments on the preferred shares outstanding were made as required by the Treasury Department’s Small Business Lending (SBLF) Program. Total assets as of September 30, 2013 were $927,051,000 compared to $897,724,000 as of September 30, 2012. Our net loans increased by $10,615,000 since September 30, 2012. During this same time frame, our deposits decreased by $10,840,000. At September 30, 2013, the Company had considerable liquid assets on hand of $285,610,000 in available for sale securities, $6,979,000 in interest earning time deposits as well as $18,368,000 in cash and cash equivalents.

“During the third quarter of 2013, the Bank was able to increase our loan production and our net loans outstanding. At the same time, higher rate brokered time deposits acquired in our Oceanic Bank acquisition have been allowed to runoff. During the 12 month period ended September 30, 2013, which is also the first twelve months following our Oceanic Bank acquisition, our time deposit balances have decreased by $55,906,000 while our noninterest bearing demand deposits have grown by $15,068,000 and our savings and money market deposits have grown by $36,197,000. Overall, our deposit portfolio has performed well, with the decrease in total deposits in line with management’s projections. During the third quarter of 2013, there was an increase in the outstanding wholesale borrowings obtained from the Federal Home Loan Bank, which totaled $44,000,000 as of September 30, 2013. The Bank intends to slowly reduce the amount of our outstanding borrowings over the next twelve months by utilizing funds derived from principal repayments that occur within our investment portfolio and the slow and steady acquisition of additional deposit accounts and dollars. There was also a sizeable tax benefit recorded during the third quarter of 2013. Based on the filing of our 2012 income tax returns and a review of our expected profitability levels, the Bank was able to reverse, in total, our outstanding deferred tax asset valuation allowance,” stated Tom McGraw, Chief Executive Officer.

“During the third quarter, the Bank’s loan production activity was up substantially. Borrowers are beginning to make additional real estate investments in our service area. Overall, our assets grew by 2.8% during the quarter. Our stockholders’ equity increased during the third quarter by 3.0% and we remain “well capitalized” by regulatory definitions. As our capital base will allow, it is the intent of our Board to make additional redemptions of outstanding Small Business Lending Program preferred stock. The Oceanic Bank purchase has been fully integrated into the operations of the Company and our capital is growing in line with our growth in assets. Steps taken by management to prudently reduce our future noninterest expenses by closing some of our branch offices is making a difference. Our salary and benefit costs were $213,000 lower during the third quarter of 2013 when compared to the prior quarter. We understand that we must meet or exceed our customer’s expectations relative to their banking experience with us in order for us to continue to grow and be a positive influence in the communities we serve. For 50 years, we have built our organization around the idea that we must continually earn our customer’s business,” continued CEO Tom McGraw.
