       On April&amp;#160;1, 2010, we purchased PWP Holdings, Inc. and PWP
       Industries for $203&amp;#160;million, which includes a
       $3&amp;#160;million working capital adjustment. The results of this
       business have been included in the consolidated financial
       statements as of that date.
   &lt;/div&gt;

       The total cost of the acquisition was allocated to the assets
       acquired and the liabilities assumed based on their respective
       fair values. Allocations were based on preliminary estimates of
       the fair market value of assets and
   liabilities, which are subject to revision based on receipt of
       final appraisals. Goodwill and other intangible assets recorded
       in connection with the acquisition totaled $100&amp;#160;million and
       $15&amp;#160;million, respectively. Recorded intangible assets
       pertaining to customer relationships and non-compete agreements
       are being amortized over a
       &lt;font style="white-space: nowrap"&gt;15-year&lt;/font&gt;
       period.
