Operating Results

Net interest margin for the second quarter of 2015 was 3.73%, compared to 3.72% for the prior quarter, and 3.66% for the second quarter of 2014. During the second quarter of 2015, our average interest-earning assets increased by $134.2 million, while our average interest-bearing liabilities increased by $89.1 million, compared to the second quarter of 2014. In addition, the yield on our interest-earning assets improved by one basis point, and the cost of our interest-bearing liabilities declined by five basis points, as compared to the second quarter of 2014.

The increase in noninterest income during the three and six month periods ended June 30, 2015 relates primarily to increases in loan and mortgage fee income and other income. A significant portion of our loan fee income relates to income derived from mortgage originations of $1.3 million and $2.5 million for the three and six months ended June 30, 2015, respectively, and $576 thousand and $880 thousand for the three and six months ended June 30, 2014, respectively.

The increase in noninterest expense during the 2015 periods relates primarily to an increase in salaries and benefits, partially offset by a decrease in other noninterest expense. In addition, real estate owned expenses increased by $860 thousand during the six months ended June 30, 2015, as compared to the prior year.

During the three months ended June 30, 2015, we recorded total credit costs of $1.1 million, including a $1.0 million provision for loan losses and $93 thousand expenses related to the sale and management of other real estate owned.

Net loan charge-offs for the second quarter of 2014 were $560 thousand, or 0.28% of average loans, annualized. For the six months ended June 30, 2015 and 2014, total credit costs were $2.5 million and $2.0 million, respectively. Our allowance for loan losses was $12.9 million, or 1.34% of loans, at June 30, 2015 which provides approximately 194% coverage of nonaccrual loans, compared to $11.1 million, or 1.37% of loans, and approximately 90% coverage of nonaccrual loans at June 30, 2014.

Nonperforming assets were $9.6 million, or 0.85% of total assets, as of June 30, 2015. Comparatively, nonperforming assets were $10.0 million, or 0.97% of total assets, at December 31, 2014, and $13.6 million, or 1.40% of total assets, at June 30, 2014. Of the $9.6 million in total nonperforming assets as of June 30, 2015, nonperforming loans represent $6.7 million and other real estate owned represents $2.9 million.
