Stockholders’ Equity

We paid a quarterly dividend of $0.085 per share in each quarter of 2015.

During 2015, we repurchased 0.9 million shares of our common stock for $4.6 million under our stock repurchase programs that were publicly announced in August of 2014 and 2012. Under the program announced in August 2014 our Board of Directors has authorized us to spend up to $20.0 million to repurchase shares of our outstanding common stock. As of December 31, 2015, we had authorization to spend $11.4 million to repurchase additional shares under this program. From 1997 through December 2015, we have paid more than $1.2 billion to repurchase 67.9 million shares under this program and previously announced programs.

During 2015, we received 170,567 shares of our common stock, with an estimated market value of $1.1 million, in connection with vesting of shares as shares are returned to treasury to pay for an awardee’s tax obligation.
