3. STOCKHOLDERS’ EQUITY AND EQUITY COMPENSATION PLANS

Stock Repurchase Program. We currently have a stock repurchase program, approved by our Board of Directors (the “Board”), authorizing us to repurchase our common stock from time-to-time as market and business conditions warrant (the “Stock Repurchase Program”). We did not repurchase any shares under our Stock Repurchase Program during the six months ended June 30, 2014. During the six months ended June 30, 2013, we repurchased 0.5 million shares of our common stock for $10.0 million (weighted-average price of $20.21 per share). As of June 30, 2014, the total remaining number of shares available for repurchase under the Stock Repurchase Program totaled 2.1 million shares.

Stock Repurchases for Tax Withholdings. In addition to the above mentioned stock repurchases, during the six months ended June 30, 2014 and 2013, we repurchased and then cancelled 0.2 million shares of common stock for $6.6 million and 0.2 million shares of common stock for $4.9 million, respectively, in connection with minimum tax withholding requirements resulting from the vesting of restricted common stock under our stock incentive plans.

Dividends. In June 2013, the Board approved the initiation of a quarterly cash dividend to be paid to our stockholders. During the second quarter of 2014, the Board approved a quarterly cash dividend of $0.1575 per share of common stock, totaling $5.4 million. During the second quarter of 2013, the Board approved a quarterly cash dividend of $0.15 per share of common stock, totaling $5.1 million. Dividends for the six months ended June 30, 2014 and 2013, totaled $10.5 million and $5.1 million, respectively.

Stock Incentive Plan. In May 2014, our stockholders approved an increase of 2.9 million shares authorized for issuance under the 2005 Stock Incentive Plan, from 15.8 million shares to 18.7 million shares.
