Net interest margin improved 7 basis points to 3.36 percent in the quarter from 3.29 percent in the last year period. Efficiency ratio for the quarter improved to 63.90 percent from 63.96 percent in the previous year period. A decline in efficiency ratio indicates a rise in profitability.

Edward J. Wehmer, president and chief executive officer, commented, "Wintrust reported record net income of $58.4 million for the first quarter of 2017. These results were driven by our momentum from 2016 carrying into 2017 with continued steady loan growth in the first quarter. The first quarter of 2017 was also characterized by our increased net interest margin, improved credit quality metrics and reduced operating costs, while offsetting an expected decrease in mortgage banking revenue. As we saw in the first quarter, the structure of our balance sheet is well positioned to take advantage of higher interest rates, and is designed to provide an internal hedge to offset lower earnings from our mortgage banking operations and from reduced revenue from our covered call option program."
