INCOME TAXES

The worldwide effective income tax rates for the fiscal six months of 2012 and 2011 were 24.9% and 21.2%, respectively. The higher effective tax rate in 2012 as compared to 2011 was primarily due to lower tax rates associated with the Synthes integration and transaction costs and litigation accruals which added 2.8 points to the effective tax rate. The expiration of the Research and Development tax credit at year end 2011 increased the 2012 tax rate by 0.6 points.
