Andrea G. Short, President and Chief Executive Officer, commented, “We are pleased to announce that we achieved record quarterly net income during the third quarter along with net interest margin expansion and an improved efficiency ratio. Average loans and leases grew $112.77 million, up 1.58% while average deposits increased marginally due to seasonal outflows of public fund deposits, compared to the previous quarter. Average year-to-date deposits, net of brokered deposits, increased $238.74 million or 3.50% compared to the prior year. Strong credit quality continued during the quarter with low net charge-offs, a lower provision for credit losses, and a reduction in nonperforming assets. Our liquidity and capital positions remained strong during the quarter.
