Return on average assets and return on average equity were 1.45% and 13.00%, respectively, for the nine months ended September 30, 2018, compared to 1.14% and 10.41% for the same period in 2017.

On December 22, 2017, H.R.1, known as the “Tax Cuts and Jobs Act,” was signed into law. H.R.1, among other things, reduced the corporate income tax rate to 21% effective January 1, 2018. As a result of passage of the new tax law, Farmers effective tax rate decreased from 25.5% for the nine months ended September 30, 2017 to 14.7% for the nine months ended September 30, 2018. It is important to note that also as a result of the new tax law, Farmers determined that its net deferred tax assets needed to be reduced in the fourth quarter of 2017 by approximately $1.8 million, representing an impact on earnings per share of approximately $0.06 per diluted share for that fourth quarter, based on that quarter’s weighted average diluted shares outstanding of approximately 27.5 million.

Kevin J. Helmick, President and CEO, stated, “We are pleased to report another strong quarter which is the result of the successful execution of our strategic plan, continued strong loan growth, higher levels of noninterest income and a lower effective income tax rate.”

2018 Third Quarter Financial Highlights

Total loans were $1.69 billion at September 30, 2018, compared to $1.55 billion at September 30, 2017, representing an increase of 9.0%. The increase in loans is a direct result of Farmers’ focus on loan growth utilizing a talented lending and credit team, while adhering to a sound underwriting discipline. The increase in loans has occurred in the commercial and commercial real estate, residential real estate and agricultural loan portfolios. Loans now comprise 78.8% of the Bank’s average earning assets for the quarter ended September 30, 2018, an improvement compared to 77.6% for the same period in 2017. This improvement, along with the interest rate environment, has resulted in a 15.4% increase in loan income in the third quarter of 2018 compared to the same quarter in 2017.

Non-performing assets to total assets remain at a low level, currently at 0.40%. Early stage delinquencies also continue to remain at low levels, at $10.6 million, or 0.63% of total loans, at September 30, 2018. Net charge-offs for the current quarter were $338 thousand, compared to $592 thousand in the same quarter in 2017 and annualized net charge-offs as a percentage of average net loans outstanding is only 0.08% for the quarter ended September 30, 2018. Lending to the energy sector is insignificant and less than 1% of the loan portfolio.

The net interest margin for the three months ended September 30, 2018 was 3.86%, a 10 basis points decrease from the quarter ended September 30, 2017. In comparing the third quarter of 2018 to the same period in 2017, asset yields increased 21 basis points, while the cost of interest-bearing liabilities increased 41 basis points. Most of this increase was the result of higher rates paid on short-term borrowings and time deposits, consistent with increases in the federal funds sold rate. The net interest margin is impacted by the additional accretion as a result of the discounted loan portfolios acquired in the previous mergers, which increased the net interest margin by 4 and 3 basis points for the quarters ended September 30, 2018 and 2017, respectively.

Noninterest income increased 6.9% to $6.5 million for the quarter ended September 30, 2018 compared to $6.1 million in the same quarter of 2017. Trust fees increased $219 thousand or 13.6% in comparing the third quarter of 2018 to the same quarter in 2017. In the third quarter of 2018 investment commissions increased $89 thousand or 48.4%, service charges on deposit accounts increased $74 thousand or 6.9% and net gains on sale of loans increased $46 thousand or 6.1% from the third quarter in 2017. These increases were offset by a drop in other operating income of $70 thousand or 15%.

Farmers has remained committed to managing its level of noninterest expenses. Total noninterest expenses for the third quarter of 2018 increased 2.5% to $16.2 million compared to $15.8 million in the same quarter in 2017, primarily a result of increases in other operating expenses of $397 thousand which included $150 thousand in captive insurance losses and core processing charges of $76 thousand, offset by a $270 thousand decrease in merger related costs. It is important to note that annualized noninterest expenses measured as a percentage of quarterly average assets decreased from 2.96% in the third quarter of 2017 to 2.85% in the third quarter of 2018.

The efficiency ratio for the quarter ended September 30, 2018 improved to 58.70% compared to 59.93% for the same quarter in 2017. The main factors leading to this improvement were the increase in net interest income and noninterest income and a lower level of noninterest expenses relative to average assets as explained in the preceding paragraphs.

Mr. Helmick added, “We are encouraged by our financial results for the first three quarters of 2018 and look to use this momentum to sustain strong performance for the remainder of the year. As always, we will remain focused on delivering for the businesses, families and communities we serve.”
