Net investments in foreign subsidiaries
We are also exposed to the impact of foreign exchange fluctuations on our investments in wholly-owned foreign subsidiaries denominated in a currency other than the U.S. dollar, which could adversely impact the U.S. dollar value of these investments and therefore the value of future repatriated earnings. During fiscal 2008, we began to hedge certain net investment positions in Euro-functional currency foreign subsidiaries to mitigate the effects of foreign exchange fluctuations on net investments, with the effect of preserving the value of future repatriated earnings. In accordance with FAS 133, the effective portion of the change in fair value of the forward contracts designated as net investment hedges is recorded in the cumulative translation adjustment component of accumulated other comprehensive income. Any ineffective portion, which was not material for any year presented, is immediately recognized in earnings as a component of other (income) expense, net. To minimize credit risk, we have structured these net investment hedges to be generally less than six months in duration. Upon maturity, the hedges are settled based on the current fair value of the forward contracts with the realized gain or loss remaining in OCI; concurrent with settlement, we enter into new forward contracts at the current market rate. The impact of net investment hedges reflected in OCI was a pre-tax gain (loss) of $161.4 million and ($68.6) million in 2009 and 2008, respectively. Cash flows from net investment hedge settlements totaled $191.3 million and ($76.0) million in 2009 and 2008, respectively.
