Recoverability Schedule of Inventory Assets Held for Development, by Reportable Segment

The table below summarizes the results of our undiscounted cash flow analysis by reportable segment, where applicable, for the quarters ended March 31, 2016 and March 31, 2015:

($ in thousands)		Undiscounted Cash Flow Analyses Prepared
Segment (a)	# of Communities on Watch List (b)	# of Communities	Pre-analysis Book Value (BV)		Aggregate Undiscounted Cash Flow as a % of BV (c)
Quarter Ended March 31, 2016
West	2	2	$	20,809	108.0	%
Corporate and unallocated (d)	—	—	1,105		N/A (e)
Total	2	2	$	21,914
Quarter Ended March 31, 2015
West	1	—	$	—	—	%

^(a) We have elected to aggregate our disclosure at the reportable segment level because we believe this level of disclosure is most meaningful to the readers of our financial statements.

^(b) Totals in this column exclude communities that are closing out (and have less than 10 closings remaining), as well as communities that are excluded due to certain qualitative considerations that would imply that low profitability levels are temporary in nature.

^(c) An aggregate undiscounted cash flow as a percentage of book value under 100% would indicate a possible impairment and is consistent with our “watch list” methodology. While this metric was above 100% for the current quarter in total, the community that we ultimately impaired was below 100%, while the community we did not impair was above 100%.

^(d) Amount represents capitalized interest and indirects balance related to the communities for which an undiscounted cash flow analysis was prepared. Capitalized interest and indirects are maintained within our Corporate and unallocated segment.

^(e) N/A - not applicable.
