[1] The foreign currency translation adjustments relate primarily to the strengthening of the U.S. Dollar relative to the local currencies our subsidiaries, principally the Euro and British Pound Sterling. Foreign currency translation adjustments, net of tax, includes net gains from fair value adjustments at June 30, 2012 of $60.9 million after tax ($104.5 million before tax) and net gains from fair value adjustments at December 31, 2011 of $46.2 million after tax ($79.1 million before tax) associated with net investment hedges (See Note 5). The remaining balance in currency translation adjustments excludes income taxes due to the Company’s practice and intention to reinvest the earnings of its foreign subsidiaries in those operations.
