16.    Subsequent event

On March 10, 2016, the Company announced that the Board of Directors authorized a new share repurchase program (the 2016 Share Repurchase Program) pursuant to which the Company may repurchase up to $425,000 of the Company’s common stock. The 2016 Share Repurchase Program authorization revokes the previously authorized but unused amounts from the 2014 Share Repurchase Program. The 2016 Share Repurchase Program does not have an expiration date and may be suspended or discontinued at any time. As part of the 2016 Share Repurchase Program, the Company entered into an Accelerated Share Repurchase (ASR) agreement with Goldman, Sachs & Co. to repurchase $200,000 of the Company’s common stock. Under the ASR agreement, the Company paid $200,000 to Goldman, Sachs & Co. and received an initial delivery of 852 shares in the first quarter of 2016, which represents 80% of the total shares the Company expects to receive based on the market price at the time of the initial delivery. The final number of shares delivered upon settlement of the agreement will be determined with reference to the average price of the Company’s common stock over the term of the ASR agreement.
