Fair Value Disclosures [Abstract]

Assets measured at fair value on a nonrecurring basis

The following table presents the fair value hierarchy and our assets measured at fair value on a nonrecurring basis (in thousands):

	Fair Value Hierarchy	For the Years Ended November 30,
Description		2017		2016
Inventories (a)	Level 2	$	—	$	3,657
Inventories (a)	Level 3	38,357		37,329

(a) Amounts represent the aggregate fair value for real estate assets impacted by inventory impairment charges during the applicable period, as of the date that the fair value measurements were made. The carrying value for these real estate assets may have subsequently increased or decreased from the fair value reflected due to activity that has occurred since the measurement date.

The following table presents the fair value hierarchy, carrying values and estimated fair values of our financial instruments, except those for which the carrying values approximate fair values (in thousands):
