[1] | (1) Represents activity related to our remaining vacant space liability for U.S. large-format store closures in fiscal 2013. We may continue to incur immaterial adjustments to the liability for changes in sublease assumptions or potential lease buyouts. In addition, lease payments for vacated stores will continue until leases expire or are terminated. The remaining vacant space liability was $18 million at January 30, 2016.
[2] | (2) Activity primarily relates to our fiscal 2013 Best Buy Europe restructuring program, which is included in discontinued operations due to the sale of our 50% ownership interest in Best Buy Europe in fiscal 2014. Restructuring charges primarily consist of property and equipment impairments and employee termination benefits.
