Share Repurchases

In November 2012, our Board of Directors authorized a share repurchase program. In February 2017, our Board of Directors increased the amount that we are authorized to expend on future repurchases to $1,000.0 under our repurchase program, which superseded all prior repurchase programs. The entire amount authorized pursuant to this February 2017 Board approval has been utilized. On October 22, 2019, the Board of Directors approved a share repurchase authorization of up to $1,000.0. On July 28, 2020, the Board of Directors approved a new share repurchase authorization of up to an additional $1,500.0. The repurchase program does not have an expiration date and we are not obligated to acquire a particular number of shares. The repurchase program may be discontinued at any time at our discretion. Under the program, we repurchased 0.6 and 3.1 shares of our common stock at a cost of $73.5 and $334.6 during the three months ended September 30, 2020 and 2019, respectively. During the nine months ended September 30, 2020 and 2019, we repurchased 4.2 and 3.5 shares of our common stock at a cost of $434.3 and $383.5, respectively.

Subsequent to September 30, 2020, we repurchased 0.4 shares of common stock under our repurchase program at a cost of $45.2. As of October 27, 2020, there is a total of $2,055.9 remaining for repurchases under the repurchase program.
