Stockholders' Equity

Treasury Stock

In July 2010, our Board of Directors approved a common stock purchase plan to purchase up to $40.0 million of our common stock. This plan has no expiration date. During the three months endedMarch 31, 2018, we did not purchase any shares of our common stock under the stock purchase plan. As of March 31, 2018, the remaining authorized amount under this purchase plan is approximately $7.2 million. We are currently limited on share purchases in accordance with the terms and conditions of our Credit Facility (see Note 16: Long-Term Obligations). 

For the three months ended March 31, 2018, we withheld 23,101 shares of our common stock from employee vested restricted stock units in consideration for $5.3 million in payments made on the employee's behalf for their minimum statutory income tax withholding obligations. Treasury stock is used to issue shares for stock option exercises, restricted stock grants and employee stock purchase plan stock purchases.
