Acquisition of Controlling Interest in Equity Method Investment
8. Acquisition of Controlling Interest in Equity Method Investment

Effective February 1, 2011, we acquired a controlling interest in the Clemenger Group, our affiliate in Australia and New Zealand, increasing our equity ownership from 46.7% to 73.7%. In connection with this transaction as required by FASB Accounting Standards Codification Topic 805 - Business Combinations, in the first quarter of 2011 we recorded a non-cash gain of $123.4 million resulting from the remeasurement of the carrying value of our equity interest to the acquisition date fair value. The difference between the fair value of our shares at the acquisition date and the carrying value of our investment held prior to the acquisition resulted in the remeasurement gain.
