Payments For Repurchase Of Equity [Abstract]

12.	Share Repurchases

On November 1, 2017, the Board authorized a new share repurchase program, under which the Company may repurchase up to $500.0 in shares of Common Stock (the “2017 Share Repurchase Program”). The 2017 Share Repurchase Program does not have an expiration and will replace the 2016 Share Repurchase Program. The Company also continued its 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 the Company’s incentive plans.

In 2017, the Company purchased approximately 8.2 million shares of Common Stock for $400.0, of which $125.0 was purchased under the evergreen share repurchase program, $100.0 was purchased under the 2017 Share Repurchase Program, and $175.0 was purchased under the 2016 Share Repurchase Program. As a result of the Company’s purchases, there remained $400.0 under the 2017 Share Repurchase Program as of December 31, 2017.
