Share Repurchases On November 1, 2017, the Board authorized a share repurchase program, under which the Company may repurchase up to $500.0 in shares of Common Stock (the “2017 Share Repurchase Program”).

In December 2020, the Company entered into an accelerated share repurchase (“ASR”) contract with a commercial bank to purchase Common Stock. The Company paid $300.0 to the bank, inclusive of fees, and received an initial delivery of shares equal to $270.0, or 3.1 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 2021, the bank delivered an additional 0.4 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.
