Stock Repurchase Program	7. Stock Repurchase Activity In November 2015, the Board of Directors (Board) authorized a Stock Repurchase Program (Program) of $300.0 million to repurchase our common stock through February 2, 2019. The Program replaced an existing program and authorizes repurchases of our common stock in open market or negotiated transactions, with the amount and timing of repurchases dependent on market conditions and at the discretion of our management. In addition to the Program, we also acquire shares of our common stock from holders of restricted stock unit awards to satisfy tax withholding requirements due at vesting. Shares acquired from holders of restricted stock unit awards to satisfy tax withholding requirements do not reduce the Program authorization.
