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 for the years ended November 30, 2013 and 2012 (in thousands):

	Fair Value
Description	Hierarchy	November 30, 2013 (a)		November 30, 2012 (a)
Long-lived assets held and used	Level 3	$	1,143	$	39,851

(a) Amounts represent the aggregate fair value for communities or land parcels where we recognized inventory impairment charges during the period, as of the date that the fair value measurements were made. The carrying value for these communities or land parcels may have subsequently increased or decreased from the fair value reflected due to activity that has occurred since the measurement date.
