Stockholders’ Equity
In May 2014, our board of directors approved a share repurchase program authorizing the repurchase of up to $50.0 million of our outstanding common stock for a period of up to one year after the approval date. Shares repurchased under the plan are retired. Our board of directors approved a one year extension of this program in both 2015 and 2016. On April 28, 2017, our board of directors again approved a one year extension of the share repurchase program. The terms of this extension permit the repurchase of up to $50.0 million of our common stock during the period commencing on the extension day and ending on May 4, 2018.
There was no repurchase activity during the three months ended March 31, 2018 and 2017.
