5.	Shareholders’ Equity and Earnings Per Common Share

In December, 2018, our Board of Directors authorized a share repurchase plan (the “Repurchase Plan”) to buy back up to 5% of our outstanding common stock through December 31, 2019. In May 2019, we completed the repurchase of 5% of our outstanding common shares. In June 2019, our Board of Directors authorized a 300,000 share expansion of the 2019 repurchase plan. We expect to accomplish any remaining repurchases through open market transactions, though we could execute repurchases through other means, such as privately negotiated transactions. The timing and amount of any share repurchases will depend on a variety of factors, including, among others, securities law restrictions, the trading price of our common stock, regulatory requirements, potential alternative uses for capital, and our financial performance. The Repurchase Plan does not obligate us to acquire any particular amount of common stock, and it may be modified or suspended at any time at our discretion. We expect to fund any repurchases from cash on hand. During the nine month periods ended September 30, 2019 and 2018 repurchases were made totaling 1,204,688 shares and zero shares of common stock, respectively for an aggregate purchase price of $26.3 million and zero, respectively.

Weighted average stock options outstanding that were not considered in computing diluted net income per common share because they were anti-dilutive were zero for the three and nine month periods ended September 30, 2019 and 2018, respectively.
