Stock Repurchase Program. We currently have a stock repurchase program, approved by our Board, authorizing us to repurchase shares of our common stock from time-to-time as market and business conditions warrant (the “Stock Repurchase Program”). During the third quarter and nine months ended September 30, 2023, we repurchased approximately 1,991,000 shares of our common stock for $107.0 million (weighted-average price of $53.73 per share). During the third quarter of 2022 we repurchased approximately 488,000 shares of our common stock for $27.9 million (weighted-average price of $57.27 per share), and during the nine months ended September 30, 2022 we repurchased approximately 1,114,000 shares of our common stock for $65.5 million (weighted-average price of $58.80 per share), respectively.

As part of the 2022 Inflation Reduction Act, effective January 1, 2023, a one percent excise tax is imposed on net share repurchases during the year. As of September 30, 2023, we accrued $0.9 million for the excise tax which is included as a cost of treasury stock, however this is not reflected in the share repurchase amounts above.

As of September 30, 2023, the total remaining number of shares available for repurchase pursuant to the prior authorization (as defined below) under the Stock Repurchase Program totaled 0.1 million shares. In August 2023, our Board authorized an additional $100.0 million of repurchases under the Stock Repurchase Program in addition to, and after the repurchase of, the remaining 0.1 million shares under the prior authorization.

Stock Repurchases for Tax Withholdings. In addition to the above-mentioned stock repurchases, during the third quarters of 2023 and 2022, we repurchased and then cancelled approximately 3,000 shares of common stock for $0.1 million and approximately 7,000 shares of common stock for $0.4 million, respectively, and during the nine months ended September 30, 2023 and 2022 we repurchased and then cancelled approximately 171,000 shares of common stock for $9.6 million and approximately 132,000 shares of common stock for $8.4 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 August 2023, we increased the number of shares of our common stock authorized and reserved for issuance under the Amended and Restated 2005 Stock Incentive Plan by 2.9 million shares to a total of 27.9 million shares. This increase was approved by our stockholders at our 2023 Annual Meeting.

Cash Dividends. During the third quarter of 2023, our Board approved a quarterly cash dividend of $0.28 per share of common stock, totaling $8.7 million. During the third quarter of 2022, our Board approved a quarterly cash dividend of $0.265 per share of common stock, totaling $8.4 million. Dividends declared for the nine months ended September 30, 2023 and 2022 totaled $26.4 million and $25.4 million, respectively.

Warrants. In 2014, in conjunction with the execution of an amendment to our 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 solutions based on various milestones. The Stock Warrants have a ten-year term and an exercise price of $26.68 per warrant.

As of September 30, 2023, 1.0 million Stock Warrants remain issued, none of which have vested. The remaining unvested Stock Warrants will be accounted for as a customer contract cost asset once the performance conditions necessary for vesting are considered probable.
