Share Repurchases
In March 2017, the Board authorized a share repurchase program to purchase up to $1,500. The program has no expiration date, but it may be suspended or discontinued at any time. In addition to this publicly announced program, we have a separate Board authorization to purchase shares to offset the impact of dilution from shares issued under our stock compensation plans.
During the three-month period ended October 29, 2017, we repurchased 2 million shares at a cost of $86. Of this amount, $75 was used to repurchase shares pursuant to our March 2017 publicly announced share repurchase program. Approximately $1,296 remained available under the March 2017 program as of October 29, 2017. During the three-month period ended October 30, 2016, we repurchased 2 million shares at a cost of $112.
