Shareholders' Equity
Since the inception of the Company's stock repurchase plan in 2004 through September 30, 2021, the Company's Board of Directors has authorized the repurchase of $1.5 billion of the Company's common stock. 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.
Under this program, as of September 30, 2021, the Company had repurchased 28.1 million shares at an aggregate purchase price of $1,145.0 million and has $355.0 million remaining available. During the three and nine months ended September 30, 2021, the Company purchased an aggregate of $72.3 million and $127.2 million, respectively, of the Company's common stock under this program.
