Common Stock Repurchase Program

In June 2016, as part of its common stock repurchase program, the Company entered into an accelerated share repurchase program with a third-party financial institution under which it made an upfront payment of $100 million in exchange for an initial delivery of 0.9 million shares of its Class A common stock, representing 90% of the total shares that were ultimately expected to be delivered over the program's term (the "ASR Program"). The initial shares received, which had an aggregate cost of $90 million based on the June 20, 2016 closing share price, were immediately retired and recorded as an increase to treasury stock.

In September 2016, at the ASR Program's conclusion, the Company received 0.1 million additional shares and accordingly recorded a related $10 million increase to treasury stock. The number of additional shares delivered was based on the volume-weighted average price per share of the Company's Class A common stock over the term of the ASR Program, less an agreed upon discount. The average price per share paid for all of the shares delivered under the ASR Program was $98.48.

A summary of the Company's repurchases of Class A common stock under its common stock repurchase program, including the ASR Program, is as follows:



	Six Months Ended
	September 30, 2017		October 1, 2016
	(millions)
Cost of shares repurchased	$	—	$	100.0
Number of shares repurchased	0.0		1.0

As of September 30, 2017, the remaining availability under the Company's Class A common stock repurchase program was approximately $100 million. Repurchases of shares of Class A common stock are subject to overall business and market conditions.

In addition, during each of the six-month periods ended September 30, 2017 and October 1, 2016, 0.2 million shares of Class A common stock, at a cost of $14.6 million and $14.9 million, respectively, were surrendered to or withheld by the Company in satisfaction of withholding taxes in connection with the vesting of awards under the Company's 1997 Long-Term Stock Incentive Plan, as amended (the "1997 Incentive Plan"), and its Amended and Restated 2010 Long-Term Stock Incentive Plan (the "2010 Incentive Plan").

Repurchased and surrendered shares are accounted for as treasury stock at cost and held in treasury for future use.

Dividends

Since 2003, the Company has maintained a regular quarterly cash dividend program on its common stock. The second quarter Fiscal 2018 dividend of $0.50 per share was declared on September 15, 2017, was payable to stockholders of record at the close of business on September 29, 2017, and was paid on October 13, 2017. Dividends paid amounted to $81.1 million and $82.6 million during the six-month periods ended September 30, 2017 and October 1, 2016, respectively.
