Impairmentsin 2011 reflectwrite-downsto estimates of fair value less costs to sell the assets of our Arkoma basin operations.These nonrecurring fair value measurements, which fall within Level 3 of the fair value hierarchy,are based on probability-weighted discounted cash flow analyses that include purchase offers we have received for the assets.

The assets of our discontinued operations comprise significantly less than 0.5 percent of our total consolidated assets as of September 30, 2011, and December 31, 2010, and are reported primarily within other current assets and deferred charges and other assets and deferred charges, respectively, on our Consolidated Balance Sheet. Liabilities of our discontinued operations are insignificant for these periods.
