	1	The goodwill of divested businesses relates to the 2011 divestiture as discussed in Note 14.

We test goodwill for impairment on an annual basis or more frequently if events or circumstances change in a manner that would more likely than not reduce the fair value of a reporting unit below its carrying value. While we have not completed our annual test and have not identified any events or changes in circumstances that indicate the fair value of any of our reporting units is below its carrying value, the timing of a sustained recovery in the construction industry may have a significant effect on the fair value of our reporting units. A significant decrease in the estimated fair value of one or more of our reporting units could result in the recognition of a material, noncash write-down of goodwill that would reduce equity and result in an increase in our total debt as a percentage of total capital (42.1% as of September 30, 2011). Our current bank credit facility and the indenture governing our notes contain a covenant limiting our total debt as a percentage of total capital to 65%. We believe that it is highly unlikely that any potential write-down in goodwill would result in a violation of this covenant.
