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):

		November 30, 2019							November 30, 2018
Description	Fair Value Hierarchy	Pre-Impairment Value		Inventory Impairment Charges			Fair Value (a)		Pre-Impairment Value		Inventory Impairment Charges			Fair Value (a)
Inventories (a)	Level 3	$	41,160	$	(14,031	)	$	27,129	$	70,156	$	(26,104	)	$	44,052

(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.
