Shareholders' Equity  

Since the inception of the Company's stock repurchase plan in 2004 through September 30, 2022, the Company's Board of Directors has authorized the repurchase of $2.0 billion of the Company's common stock, including an additional $500 million approved by the Company’s Board of Directors at its regular board meeting in April 2022. Shares of the Company's common stock may be purchased in the open market or through privately negotiated transactions, subject to market conditions, and generally settle subsequent to the trade date.

Under this program as of September 30, 2022, the Company had repurchased 31.7 million shares at an aggregate purchase price of $1,470.6 million and had $529.4 million remaining available. During the nine months ended September 30, 2022, the Company repurchased an aggregate of $286.9 million of the Company's common stock under this program. The Company did not repurchase common stock during the three months ended September 30, 2022.
