Total noninterest expense	$	30,354	$	28,570	$	26,655	$	1,784	6.2	%	$	3,699	13.9	%

•Noninterest expense increased $3.7 million, or 13.9%, from the prior-year quarter and $1.8 million from the linked-quarter. The increase compared to the prior-year quarter was due to higher base salaries from an annual merit increase and the Merger-related costs. The increase compared to the linked-quarter was due to the Merger-related costs, offset by a decrease in consulting costs related to technology initiatives for business intelligence and a data center relocation. These projects have been suspended due to the pending Merger.

•The taxable equivalent efficiency ratio* was 68.1% for the second quarter of 2018, compared to 62.8% and 64.1%, respectively, for the prior-year and linked-quarters. The taxable equivalent efficiency ratio is directly impacted by the tax rate paid by the Company. The efficiency ratio increases with a decrease in tax rates, and decreases with an increase in tax rates. Although the TCJA benefits net income due to the reduction in the federal income tax rate from 35% to 21%, it increases the taxable equivalent efficiency ratio.

Provision for Income Taxes

The effective tax rate was 18.1% in the second quarter of 2018, compared to 25.0% in fiscal 2017 (excluding a $7.2 million charge related to the TCJA). The majority of the decrease in the tax rate relates to the TCJA that became effective in the first quarter of 2018.

Prospectively, until closing of the Merger, the Company estimates that its effective tax rate will be approximately 18-19%.

•Fluctuations in interest rates and market prices could reduce our net interest margin and asset valuations and increase our expenses.

•Increased cybersecurity risk, including potential network breaches, business disruptions, or financial losses.
