Equity [Abstract] |
Stockholders' Equity | Stockholders’ Equity Repurchases of Class A Common Stock Repurchases of our Class A Common Stock occurred under a repurchase authorization granted by our Board of Directors and related to shares withheld as part of the vesting of restricted stock units (RSUs). On October 22, 2018, our Board of Directors approved an additional $250 million repurchase authorization of our Class A common stock, increasing our total share repurchase authorization to $500 million. Share repurchases under this authorization were as follows:
|  | Repurchases Occurring in 2021 |  | Cumulative Repurchases as of March 31, 2021
|  | Shares |  | Average Price |  | Shares |  | Average Price
Share Repurchase Authorization |  | — |  |  | $ | — |  |  | 3,719,048 |  |  | $ | 84.02 |
As of March 31, 2021, we had $187.5 million available for repurchases pursuant to our share repurchase authorization. In addition, during 2021, we repurchased 54,218 shares at an average price of $292.86 per share, for a total of $15.9 million, related to tax withholding associated with the vesting of RSUs. The repurchase of shares related to tax withholding associated with stock awards does not reduce the number of shares available for repurchase as approved by our Board of Directors. ATM Equity Offering On July 24, 2020, we entered into an ATM Equity Offering Sales Agreement, which allows us to offer and sell, from time to time, shares of our Class A common stock, no par value, having an aggregate gross sales price of up to $400 million. The shares will be issued pursuant to a registration statement on Form S-3 (File No. 333-239969), which became effective upon its filing on July 21, 2020. Under this agreement, we may enter into forward share purchase transactions. As of March 31, 2021, no amounts have been issued in relation to the ATM Equity Offering Sales Agreement.
