Treasury Stock

In March 2016, our Board of Directors authorized a share repurchase program that allows the Company to repurchase shares of our common stock up to $300 million, excluding transaction costs. The repurchases are to be effectuated in the open market, by block purchase, or possibly through other transactions managed by broker-dealers. No time limit was set for completion of the program.

During the nine months ended October 1, 2016, we repurchased 3.7 million shares for consideration of $200 million. These shares were recorded as treasury stock and accounted for under the cost method. No repurchased shares have been retired. At October 1, 2016, $100 million remains available for repurchase under the program.
