Goodwill</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Cooper has goodwill of $2.29 billion and $2.34 billion at June 30, 2010 and December 31, 2009, respectively. Goodwill is subject to an annual impairment test and Cooper has designated January 1 as the date of this test. If an event occurs, or circumstances change, that would more likely than not reduce the fair value of a reporting unit below its carrying value; an interim impairment test would be performed between annual tests. Cooper has identified eight reporting units for which goodwill is tested for impairment. The results of step one of the goodwill impairment tests as of January 1, 2010 did not require the completion of step two of the test for any reporting unit. As a result of the Tools joint venture as discussed above, Cooper completed an interim impairment test for the Tools reporting unit goodwill. The results of step one of the goodwill impairment test for the Tools reporting unit did not require the completion of step two of the test. </div> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock The carrying amount of goodwill, goodwill acquired during the year, goodwill impairment losses recognized, goodwill written off due to the sale of a business unit, goodwill not yet allocated, and any other changes to goodwill during the period in total and for each reportable segment.
