In August 2023, our board of directors approved the repurchase of up to an additional $1,000.0 million of our Class A common stock. Such approval was in addition to the amount available for repurchases under prior approvals of our board of directors, such that our total approved authority under the program is $4,000.0 million of shares of our Class A common stock through 2025.
During the nine months ended September 30, 2023, we repurchased a total of 15,738 shares of our Class A common stock in the open market, which were retired upon repurchase, for an aggregate purchase price of $1,145.3 million. As of September 30, 2023, we had $1,554.6 million of remaining authorization available for repurchases.
