Share Repurchases

7.    Share Repurchases

  On November 1, 2017, the Company’s Board of Directors (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”).  The 2017 Share Repurchase Program does not have an expiration.  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 connection with the evergreen repurchase program, in January 2019, the Company executed open market purchases of $100.0 of its Common Stock.
