       On April&amp;#160;1, 2010, we purchased PWP Holdings, Inc. and PWP
       Industries for $200&amp;#160;million. The results of this business
       have been included in the consolidated financial statements as
       of that date.

       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 $97&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.
