Inventory Impairments and Land Option Contract Abandonments [Abstract]

Summary of Quantitative Unobservable Inputs Utilized in Determining the Fair Value of Communities

The following table summarizes ranges for significant quantitative unobservable inputs we utilized in our fair value measurements with respect to the impaired communities or land parcels written down to fair value during the periods presented:

	Nine Months Ended August 31,				Three Months Ended August 31,
Unobservable Input (a)	2013			2012	2013			2012
Average selling price	$	—		$115,200 - $497,900	$	—		$152,000 - $246,200
Deliveries per month	—			1 - 6	—			2 - 4
Discount rate	—		%	17% - 20%	—		%	17% - 20%

(a) The ranges of inputs used primarily reflect the underlying variability among the various housing markets where each of the impacted communities or land parcels are located, rather than changes in prevailing market conditions.
