Credit Quality

Nonperforming loans (defined as nonaccrual loans and loans 90 days or more past due and still accruing interest) decreased $742,000, or 12.7%, to $5,093,000 at December 31, 2013 from $5,835,000 at December 31, 2012. Nonperforming loans as a percentage of total loans were 1.00% at December 31, 2013, compared to 1.19% at December 31, 2012.

The overall level of nonperforming loans decreased $123,000 to $5,093,000 at December 31, 2013 from $5,216,000 at September 30, 2013. During the fourth quarter of 2013, the Company identified five loans totaling $631,000 as additional nonperforming loans. These additions were offset by reductions in nonperforming loans totaling $754,000 due primarily to collections received on certain loans and charge-offs. Of the five loans totaling $631,000 identified as nonaccrual loans and added to nonperforming loans, the largest loan of this group totaled $240,000. This loan is a commercial loan and it has a specific reserve of $150,000. The remaining four loans in this group of nonperforming loans totaled $391,000 and no specific reserves have been established for them.

Gross loan charge-offs for the fourth quarter of 2013 were $349,000 and recoveries totaled $338,000 resulting in net charge-offs of $11,000 compared to gross loan charge-offs for the fourth quarter of 2012 of $1,051,000 and recoveries of $82,000 resulting in net charge-offs of $969,000. Gross loan charge-offs for the year ended December 31, 2013 were $1,840,000 and recoveries for the same year totaled $683,000 resulting in net charge-offs of $1,157,000, compared to gross charge-offs for the year ended December 31, 2012 of $4,702,000 and recoveries of $404,000 resulting in net charge-offs of $4,298,000.

Nonperforming assets (nonperforming loans and other real estate owned (“OREO”)) totaled $8,547,000 at December 31, 2013, a decrease of $19,711,000, or 69.8%, from the December 31, 2012 balance of $28,258,000. Nonperforming assets as a percentage of total assets were 0.93% at December 31, 2013 compared to 3.13% at December 31, 2012.

The Company’s OREO properties decreased $11,591,000 to $3,454,000 at December 31, 2013 from $15,045,000 at September 30, 2013. The decrease in OREO was due to the sale of thirteen properties totaling $11,281,000, and the write-down of certain other OREO properties totaling $937,000 during the quarter ended December 31, 2013. The decrease was partially offset by the addition of one OREO property in the amount of $627,000, which was originally purchased for expansion by the Company but subsequently concluded that it was no longer needed.
