Intangible Assets [Abstract]

Intangible Assets

NOTE 12.  INTANGIBLE ASSETS

We conduct our annual impairment testing of non-amortizable intangible assets during the fourth quarter.  In 2010 our impairment analysis determined that the carrying value of our Wood Flooring trademarks was in excess of the fair value.  We determined the fair value of these intangible assets by utilizing relief from royalty analysis that incorporated projections of revenue and cash flows.  The initial fair value for these intangible assets was determined in 2006 as part of fresh start reporting.  The fair values were negatively affected by lower expected future sales in the U.S. residential housing market.  Based on the result of the analysis, we recorded non-cash impairment charges of $22.4 million in the fourth quarter of 2010.  See Note 2 to the Consolidated Financial Statements for a discussion of our accounting policy for intangible assets.

The following table details amounts related to our intangible assets as of December 31, 2012 and 2011:
