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 second quarters of 2020 and 2019 we repurchased approximately 9,000 shares of our common stock for $0.4 million (weighted-average price of $40.74 per share) and approximately 144,000 shares of our common stock for $6.5 million (weighted-average price of $45.39 per share), respectively, and during the six months ended June 30, 2020 and 2019 we repurchased approximately 151,000 shares of our common stock for $6.8 million (weighted-average price of $44.99 per share) and approximately 393,000 shares of our common stock for $15.8 million (weighted-average price of $40.31 per share), respectively, under a SEC Rule 10b5-1 Plan. In early April 2020, we suspended stock repurchases under the Stock Repurchase Program and terminated our existing SEC Rule 10b5-1 Plan.

As of June 30, 2020, the total remaining number of shares available for repurchase under the Stock Repurchase Program totaled 4.8 million shares.

Stock Repurchases for Tax Withholdings. In addition to the above-mentioned stock repurchases, during the second quarters of 2020 and 2019 we repurchased and then cancelled approximately 2,000 shares of common stock for $0.1 million and approximately 4,000 shares of common stock for $0.4 million, respectively, and during the six months ended June 30, 2020 and 2019 we repurchased and then cancelled approximately 159,000 shares of common stock for $7.7 million and approximately 107,000 shares of common stock for $4.5 million, respectively, in connection with minimum tax withholding requirements resulting from the vesting of restricted common stock under our stock incentive plans.

Stock Incentive Plan. In May 2020, our stockholders approved an increase of 3.6 million shares authorized for issuance under the Amended and Restated 2005 Stock Incentive Plan, from 21.4 million shares to 25.0 million shares.

Cash Dividends. During the second quarter of 2020, the Board approved a quarterly cash dividend of $0.235 per share of common stock, totaling $7.8 million. During the second quarter of 2019, the Board approved a quarterly cash dividend of $0.2225 per share of common stock, totaling $7.4 million. Dividends declared for the six months ended June 30, 2020 and 2019 totaled $15.5 million and $14.7 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 2.9 million shares of our common stock (the “Stock Warrants”) as an additional incentive for Comcast to convert customer accounts onto our Advanced Convergent Platform (“ACP”) based on various milestones. The Stock Warrants have a ten-year term and an exercise price of $26.68 per warrant.

As of June 30, 2020, 1.0 million Stock Warrants remain issued, none of which were vested. The remaining unvested Stock Warrants will be accounted for as a client contract cost asset once the performance conditions necessary for vesting are considered probable.

Certain performance-based awards become fully vested upon a change in control, as defined, and the subsequent involuntary termination of employment, or death.

The other restricted common stock shares granted during the six months ended June 30, 2020 are primarily time-based awards, which vest annually 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, or death.
