[1] During the second and fourth quarters of 2018, the Company experienced negative provision expense in large part to the improvement in certain economic risk factors during those periods. This included lower classified loans, as well as the improvements in historical loan loss rates, loan delinquency, and regional unemployment conditions.

[2] During the third quarter of 2017, the Company experienced higher provision expense that was primarily related to general increases in specific allocations and increases in charge-offs within the commercial and residential real estate portfolios.

[3] 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 refund product 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 refund product provider for each transaction processed. Due to the seasonal nature of tax refund transactions, the majority of income was recorded during the first quarter.
