Review of operations

For the six month period ending June 30, 2013, net income available to common shareholders increased $372,000 or 8 percent compared to the first six months of 2012. The increase in earnings was due primarily to increases in net interest income and noninterest income and a decrease in preferred stock dividends as described below.

The $699,000 or 4 percent pretax 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 $49 million or 5 percent for the first six 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 $306,000 or 8 percent pretax increase in noninterest income was primarily the result of increases in income from trust and investment services fees, service fees on deposits and gains from the sale of residential mortgage loans, all of which represented normal business growth.

The $134,000 or 52 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. The annualized dividend rate in effect for the period ended June 30, 2013 was 1 percent, compared to approximately 2 percent for the period ended June 30, 2012.

Review of financial condition

On June 30, 2013, total assets were approximately $1.1 billion, representing a $54 million or 5 percent increase, compared to June 30, 2012. Compared to one year ago, asset growth occurred primarily in the commercial loan portfolio and was funded by an increase in core deposits. 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.
