Stock Repurchases

In February 2020, our board of directors authorized a $300 million incremental increase to our ongoing stock repurchase program. This repurchase authorization has no expiration. We retire shares in the period they are acquired and account for the payment as a reduction to stockholders' equity.

During the three months ended March 31, 2020, we repurchased 747,417 shares of common stock for approximately $40 million. As of March 31, 2020, approximately $495 million remained available for further repurchases of our common stock under all authorizations from our board of directors under this program.
