Stock Repurchases

In February 2022, our board of directors authorized a $300 million incremental increase to our ongoing stock repurchase program. This repurchase authorization has no expiration. On March 17, 2022, we completed a tender offer through which we repurchased 3,653,690 shares of common stock at a price of $86.50 per share, for total consideration of approximately $319 million, which includes costs directly attributable to the purchase.

During the six months ended June 30, 2022, we repurchased a total of 4,419,423 shares of common stock for approximately $380 million, plus costs, including shares repurchased through our tender offer.

We retire shares in the period they are acquired and account for the payment as a reduction to stockholders' equity. As of June 30, 2022, approximately $184 million remained available for further repurchases of our common stock under all authorizations from our board of directors under this program.
