Review of operations

For the nine month period ending September 30, 2013, net income available to common shareholders increased $1,178,000 or 18 percent compared to the first nine months of 2012. The increase in earnings was due primarily to an increase in net interest income and, to a lesser degree, decreases in the provision for loan losses, noninterest expense and preferred stock dividends, which more than offset a decrease in noninterest income and an increase in the provision for income taxes, as described below.

The $1,463,000 or 5 percent increase in net interest income was due primarily to a decrease in funding costs resulting from a larger proportion of low cost core deposits to total deposits and lower rates generally paid on all deposit products, which reflected unusually low market interest rates. The average balance of interest earning assets, principally commercial loans, increased approximately $51 million or 5 percent for the first nine months of 2013, compared to the same period of 2012. While the volume of earning assets increased, its effect on interest income was largely offset by lower yields, a reflection of the low interest rate environment.

The $180,000 or 16 percent decrease in the provision for loan losses was due primarily to improving credit quality and adequacy of the allowance for loan losses.

The $135,000 or 2 percent decrease in noninterest income was primarily the result of a decrease in gains from the periodic sale of investment securities. Gains from the sale of U.S. agency mortgage-back securities were greater in the first nine months of 2012 as selected instruments that no longer met the Corporation’s investment standards were liquidated. Core noninterest income, which excludes gains or losses from the sale of securities increased $252,000 or 4 percent, representing normal business growth.

The $274,000 or 1 percent decrease in noninterest expense was primarily the result of the $1,888,000 or 82 percent decrease in impairment costs associated with foreclosed real estate. The decrease in impairment costs more than offset the $1,241,000 or 11 percent increase in personnel expense, which resulted from expanding the banking franchise and normal business growth.

The $738,000 or 33 percent increase in the provision for income taxes was due to the 19 percent increase in income before income taxes.

The $134,000 or 42 percent decrease in preferred stock dividends was the result of a decrease in the dividend rate caused by the addition of loans that qualified for the U.S. Treasury’s Small Business Lending Fund Program. Dividends under this program are expected to average 1 percent this year, compared to approximately 1.5 percent for the year 2012.

Review of financial condition

On September 30, 2013, total assets were approximately $1.12 billion, representing a $52 million or 5 percent increase, compared to September 30, 2012. Compared to one year ago, asset growth occurred primarily in the commercial loan portfolio and was funded primarily by an increase in core deposits and, to a lesser degree, low-rate advances from the Federal Home Loan Bank of Pittsburgh. The growth of core deposits is a particular focus of the Corporation because the rates are relatively low, are a source of fee income and provide the opportunity to cross-sell other financial products and services. The Corporation excludes time deposits in its definition of core deposits.

As a result of profitable operations, the Corporation’s capital level remained sound as evidenced by capital ratios that exceed current regulatory requirements for well capitalized institutions as provided in the Financial Highlights section of this Earnings Release.
