Fair Value, Assets and Liabilities Measured on Nonrecurring Basis

The following table summarizes the fair value remeasurements for property and equipment impairments recorded during the three and six months ended July 29, 2017, and July 30, 2016 ($ in millions):

	Impairments								Remaining Net Carrying Value(1)
	Three Months Ended				Six Months Ended
	July 29, 2017		July 30, 2016		July 29, 2017		July 30, 2016		July 29, 2017		July 30, 2016
Property and equipment (non-restructuring)	$	1	$	3	$	6	$	8	$	—	$	—
Property and equipment (restructuring)(2)	—		—		—		7		—		—
Total	$	1	$	3	$	6	$	15	$	—	$	—

(1) Remaining net carrying value approximates fair value. Because assets subject to long-lived asset impairment are not measured at fair value on a recurring basis, certain fair value measurements presented in the table may reflect values at earlier measurement dates and may no longer represent the fair values at July 29, 2017, and July 30, 2016.
