Share Repurchases	7. Share Repurchases On October 28, 2021, the Board authorized a new share repurchase program, under which the Company may repurchase up to $1,000.0 in shares of Common Stock (the “2021 Share Repurchase Program”). The 2021 Share Repurchase Program does not have an expiration and replaced the 2017 Share Repurchase Program. All remaining dollars authorized for repurchase under the 2017 Share Repurchase Plan have been cancelled. The 2021 Share Repurchase Program did not modify the Company’s evergreen share repurchase program, authorized by the Board on January 29, 2014, under which the Company may repurchase, from time to time, Common Stock to reduce or eliminate dilution associated with issuances of Common Stock under its incentive plans. In December 2021, the Company executed open market purchases of 1.8 million shares for $170.3, inclusive of fees, of which $100.0 was purchased under the evergreen share repurchase program and $70.3 was purchased under the 2021 Share Repurchase Program. In December 2021, the Company also entered into an accelerated share repurchase contract ("ASR") with a commercial bank to purchase Common Stock. The Company paid $200.0 to the bank, inclusive of fees, and received an initial delivery of shares equal to $180.0, or 1.8 million shares. The Company used cash on hand and short-term borrowings to fund the initial purchase price. Upon the completion of the ASR, which ended in February 2022, the bank delivered an additional 0.2 million shares to the Company. The final shares delivered to the Company were determined by the average price per share paid by the bank during the purchase period. All 2.0 million shares were purchased under the 2021 Share Repurchase Program. As a result of the Company’s recent stock repurchases, there remains $729.7 of share repurchase availability under the 2021 Share Repurchase Program as of June 30, 2022.
