Subsequent Event

On May 22, 2018, the Registrant's Board of Directors approved a new share repurchase program. This new program, which is effective June 1, 2018 and expires on January 31, 2022, authorizes the Company to repurchase up to $1.0 billion of its Common Stock through open market transactions, including through Rule 10b5-1 plans and one or more accelerated share repurchase or other structured repurchase transactions, and/or privately negotiated transactions. Purchases under this new program are discretionary and will be made from time to time based on market conditions and the Company's liquidity needs. This new program will replace the Company's 2016 Program announced in January 2016 (see "Note 11. Stockholders' Equity").

Under this new program, the Registrant's Board of Directors also approved the repurchase of $250.0 million of the Company's Common Stock through an accelerated share repurchase transaction, which the Company expects to enter into during its fiscal quarter ending July 31, 2018, subject to market conditions.
