As compared with 2017, income tax expense in 2018 reflects the reduction of the corporate Federal income tax rate from 35% to 21%.
Commenting on M&T's results for the recent quarter, Darren J. King, Executive Vice President and Chief Financial Officer, noted, "M&T posted another quarter of strong financial results. Growth in net interest income, fueled by a wider net interest margin, reduced credit costs and controlled operating expenses led to an 8% rise in diluted earnings per common share compared with the second quarter. Reflecting the consistency of our earnings, we increased the quarterly common stock dividend by 25% to $1.00 per share."
