The new share repurchase program authorizes the purchase of up to $1.14 billion of our common stock through and including November 1, 2018. The new program will commence, at the option of the company, on either November 1, 2015, or the date on which we complete the purchase of $365 million of common stock under the existing stock repurchase program in fiscal 2015. Upon commencement, the new program replaces our existing stock repurchase program, which authorized the repurchase of shares to reduce or eliminate share dilution from equity programs.</link:label>
