Kevin J.

Our efficiency ratio improved to 67.96%, in the 2013 fourth quarter, representing the lowest quarter in the past two years. The improvement in our efficiency ratio is consistent with our strategy to increase fee income and decrease noninterest expenses. We are also pleased to report that net loans increased 7.5% during 2013. Most of this growth came from our commercial real estate, residential real estate and indirect loan portfolios.”

Farmers will also hire a Financial Advisor, Mortgage Loan Consultant and Universal Banker for the office located at 20325 Center Ridge Road.

2013 Financial Highlights

Total loans were $630.7 million at year-end 2013, compared to $586.6 million at year-end 2012. This represents an increase of 7.52%. The improvement in the local economy is the main factor driving the increase in loans. Most of the increase in loans has occurred in the commercial real estate, residential real estate and indirect loan portfolios. Loans comprised 56.2% of the Bank’s average earning assets in 2013, compared to 54.8% in 2012.

Net charge-offs decreased from $2.9 million for the year ended December 31, 2012 to $1.4 million in 2013. Most of the improvement occurred in the commercial and commercial real estate loan portfolios. Non-performing assets to total assets remain at a safe level, currently at 0.81%. Early stage delinquencies also remain at low levels, down $58 thousand from December 31, 2012 to $3.6 million at December 31, 2013.

The net interest margin for the quarter ended December 31, 2013 was 3.53%, an improvement of 6 basis points over the 3.47% reported for the quarter ended September 30, 2013. Asset yields increased 6 basis points, while the cost of interest-bearing liabilities remain unchanged.

The Company underwent a cost reduction program in 2013 that included the closure of two retail branch locations and the elimination of several full time positions. In addition to the cost savings initiatives, the Company also made adjustments to the fee structure for its retail and commercial banking products and services. As a result of these actions, the Company’s efficiency ratio improved to 67.96% for the quarter ended December 31, 2013, which compares favorably to the 72.48% reported in the fourth quarter in 2012.

2014 Outlook

Mr. Helmick continued: “While the economy continues to slowly improve, we are excited about the opportunities to sustain the momentum our company has seen in loan growth while maintaining our consistent asset quality levels. We also continue our discipline of closely monitoring levels of non-interest income while growing non-interest revenues.”
