NB&T Financial Group, Inc. (Nasdaq: NBTF), parent company of The National Bank and Trust Company ("NB&T"), Wilmington, Ohio, announced net income for 2014 was $4.8 million, or $1.41 basic earnings per share , an increase of 13.7% compared to $4.2 million, or $1.24 basic earnings per share, for 2013. Net income was up primarily due to an increase in net interest income of $1.1 million and a decrease in the loan loss provision of $2.1 million. These improvements were partially offset by an increase in non-interest expense of $1.1 million and a decrease in non-interest income of $1.4 million. Non-interest expenses increased in 2014 compared to 2013 primarily due to 2014 merger related expenses, bonus accrual and a true-up provision on a loss sharing agreement with the FDIC. The decrease in non-interest income is due primarily to no securities sales net gains in 2014 compared to $1.0 million in 2013.

Net income for the fourth quarter of 2014 was $1.3 million, or $.37 basic earnings per share, compared to net income of $1.0 million, or $.30 basic earnings per share, for the same period in 2013. The increase was primarily due to no loan loss provision in the fourth quarter of 2014 compared to a provision of $750,000 for the same period in 2013. In addition, net interest income increased $511,000 in the fourth quarter when compared to the same period last year, but was offset by $218,000 in merger-related expenses, a $240,000 bonus accrual and a $285,000 true-up provision on a loan loss sharing agreement with the FDIC.

Net interest income was $21.7 million for 2014, compared to $20.6 million for 2013. Net interest margin increased to 3.57% for 2014, compared to 3.37% for the previous year. Net interest income has increased primarily due to increased investment in long term tax-exempt municipal securities and slower prepayments on mortgage-related securities. As a result, investment interest income increased $1.2 million in 2014, compared to last year. In addition, lower interest expense of $405,000 in 2014 compared to 2013 contributed to the increase in net interest income. The decrease in interest expense was primarily due to continued runoff of higher priced time deposits. These two increases were partially offset by a decrease in loan interest income of $515,000, primarily due to lower average loan balances of $9.3 million in 2014 compared to 2013. Net interest income was $5.6 million for the fourth quarter of 2014, compared to $5.1 million for the fourth quarter of 2013.

The provision for loan losses for 2014 was $510,000, compared to $2.6 million the previous year. There was no provision for loan losses in the fourth quarter of 2014 compared to a provision of $750,000 during the same quarter last year. The lower 2014 loan loss provision was the result of lower charge-offs and continuing reduction in problem loans. Net charge-offs were down to $1.0 million for 2014, compared to $3.3 million in 2013. Net charge-offs for the fourth quarter of 2014 dropped to $333,000, from $2.6 million in the same quarter last year. Additionally, non-performing loans of $5.2 million at December 31, 2014, were down $616,000 compared to $5.8 million at December 31, 2013.

Total non-interest income was $8.3 million for 2014, down from $9.6 million for 2013. The decrease is primarily due to approximately $1.0 million in securities sale net gains during 2013 and a gain of $300,000 on the extinguishment of $1.0 million in trust preferred debt. There were no such gains during 2014. In addition, total NSF fees were down $272,000, or 12%, for 2014 compared to 2013. These reductions were partially offset by an increase in trust services income of $206,000, or 16%, in 2014 over 2013. Non-interest income for the fourth quarter of 2014 was $2.1 million, compared to $2.3 million for the same period last year.

Total non-interest expense was $23.5 in 2014, compared to $22.4 million in 2013. The increase is primarily due to merger-related expenses of $642,000 and a bonus accrual of $570,000. In addition, a true-up provision of $510,000 was made during 2014 under NB&T's March 2010 Purchase and Assumption Agreement with the FDIC. That agreement requires NB&T to reimburse the FDIC for a portion of the loss share funds previously paid by the FDIC to NB&T in the event losses fail to reach the expected loss level. These expenses were offset by a decrease of approximately $361,000 in state taxes due to Ohio's new financial institution tax replacing Ohio's bank franchise tax and a decrease of approximately $558,000 in professional fees, excluding merger-related expenses. Non-interest expense for the fourth quarter of 2014 was $6.0 million, compared to $5.4 million for the same period last year due to the previously discussed quarterly expenses.

On August 4, 2014, Peoples Bancorp Inc. ("Peoples") and NB&T announced the signing of an Agreement and Plan of Merger under which NB&T will be merged into Peoples. Under the terms of the agreement, shareholders of NB&T will receive 0.9319 shares of Peoples common stock and $7.75 in cash in exchange for each share of NB&T common stock. Peoples expects the acquisition of NB&T to be completed in the first quarter of 2015, subject to the satisfaction of customary closing conditions, including regulatory approvals and the approval of the shareholders of Peoples and NB&T. At that time, NB&T's offices will become branches of Peoples.

On December 16, 2014 the Board of Directors declared a dividend of $0.30 per share, payable January 26, 2015 to shareholders of record on December 31, 2014.
