[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basis, certain fair value measurements presented in the table may reflect values at earlier measurement dates and may no longer represent the fair values at August 3, 2019, and August 4, 2018.

[2] Represents activity related to operating lease assets post-adoption of ASC 842, Leases.
