Since the inception of the Company's stock repurchase plan in 2004 through June 30, 2023, the Company's Board of Directors has authorized the repurchase of $2.0 billion of the Company's common stock, excluding excise tax. 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. The repurchase program does not obligate the Company to acquire any specific number of shares or to acquire shares over any specified period of time.

During the three and six months ended June 30, 2023, the Company repurchased an aggregate of $62.9 million and $78.7 million, respectively, of common stock under this program, excluding excise tax.
