8. STOCKHOLDERS’ EQUITY AND EQUITY COMPENSATION PLANS

Stock Repurchase Program. We currently have a stock repurchase program, approved by our Board, authorizing us to repurchase our common stock from time-to-time as market and business conditions warrant (the “Stock Repurchase Program”). During the six months ended June 30, 2016 and 2015 we repurchased 0.3 million shares of our common stock for $9.5 million (weighted-average price of $36.07 per share) and 0.3 million shares of our common stock for $7.0 million (weighted-average price of $27.06 per share), respectively, under a SEC Rule 10b5-1 Plan.

As of June 30, 2016, the total remaining number of shares available for repurchase under the Stock Repurchase Program totaled 6.8 million shares.

Stock Repurchases for Tax Withholdings. In addition to the above mentioned stock repurchases, during the six months ended June 30, 2016 and 2015, we repurchased and then cancelled 0.3 million shares of common stock for $10.0 million and 0.2 million shares of common stock for $5.9 million, respectively, in connection with minimum tax withholding requirements resulting from the vesting of restricted common stock under our stock incentive plans.

Cash Dividends. During the second quarter of 2016, the Board approved a quarterly cash dividend of $0.185 per share of common stock, totaling $6.0 million. During the second quarter of 2015, the Board approved a quarterly cash dividend of $0.175 per share of common stock, totaling $5.7 million. Dividends declared for the six months ended June 30, 2016 and 2015 totaled $12.0 million and $11.5 million, respectively.

Warrants. In 2014, in conjunction with the execution of an amendment to our current agreement with Comcast Corporation (“Comcast”), we issued stock warrants (the “Warrant Agreement”) for the right to purchase up to approximately 2.9 million shares of our common stock (the “Stock Warrants”) as an additional incentive for Comcast to convert new customer accounts onto our Advanced Convergent Platform (“ACP”). The Stock Warrants have a 10-year term and an exercise price of $26.68 per warrant. As of June 30, 2016, approximately 1.0 million Stock Warrants have vested.

Upon vesting, the Stock Warrants are recorded as a client incentive asset with the corresponding offset to stockholders’ equity. The client incentive asset related to the Stock Warrants is amortized as a reduction in cloud and related solutions revenues over the remaining term of the Comcast amended agreement. As of June 30, 2016, we recorded a client incentive asset related to these Stock Warrants of $7.3 million and have amortized $2.7 million as a reduction in cloud and related solutions revenues.

The remaining unvested Stock Warrants will be accounted for as client incentive assets in the period the performance conditions necessary for vesting have been met. As of June 30, 2016, none of the Stock Warrants had been exercised.

Stock-Based Awards. A summary of our unvested restricted common stock activity during the second quarter is as follows (shares in thousands):

	Quarter Ended					Six Months Ended

Included in the awards granted during the six months ended June 30, 2016, are performance-based awards for 0.1 million restricted common stock shares issued to members of executive management, which vest in equal installments over three years upon meeting either pre-established financial performance objectives or pre-established total shareholder return objectives. The performance-based awards become fully vested upon a change in control, as defined, and the subsequent involuntary termination of employment.

All other restricted common stock shares granted during the quarter and six months ended June 30, 2016 are time-based awards, which vest annually primarily over four years with no restrictions other than the passage of time. Certain shares of the restricted common stock become fully vested upon a change in control, as defined, and the subsequent involuntary termination of employment.

We recorded stock-based compensation expense for the second quarters of 2016 and 2015 of $5.6 million and $5.4 million, respectively, and for the six months ended June 30, 2016 and 2015 of $12.1 million and $10.5 million, respectively.
