[1] During most of 2013, the Company experienced minimal to negative provision expense as a result of lower general allocations of the allowance for loan losses. General allocations were impacted by improved economic trends that include: decreasing historical loan loss factor, lower delinquencies and lower classified/criticized assets.

[2] During the fourth quarter of 2012, the Company experienced a large recovery of $1,250 on a previously charged-off commercial loan which lowered net charge-offs. The large decrease in net charge-offs contributed to a lower historical loan loss factor that created a lower level of general allocations within the allowance for loan losses.

[3] During the first quarter of 2011, the Company began taking partial charge-offs more quickly on collateral dependent impaired loans as a result of management's evaluation of the trends in the real estate market, the status of long-term, collateral dependent impaired loans and the current regulatory environment. The increases in partial charge-offs contributed to a higher historical loan loss factor, which required additional general allocations within the allowance for loan losses.

[4] The Company's noninterest income was significantly impacted by seasonal tax refund processing fees. The Bank serves as a facilitator for the clearing of tax refunds for a single tax software provider. The Bank processes electronic refund checks/deposits associated with taxpayer refunds, and will, in turn, receive a fee paid by the third-party tax software provider for each transaction processed. Due to the seasonal nature of tax refund transactions, the majority of income was recorded during the first quarter.
