In September 2015, the Company announced that the Board of Directors had approved a share repurchase program under which the Company is authorized to repurchase up to $900.0 million of the Company’s common stock. This $900.0 million share repurchase program has no stated expiration and replaced any previously authorized repurchase programs. As of June 30, 2018, the Company had approximately $567.7 million remaining available for share repurchases under the program. The Company expects any share repurchases to be made through purchases from time to time in the open market at prevailing market prices, through private transactions or block trades. The timing and amount of any repurchases will depend on market conditions, share price, applicable legal requirements and other factors.
