The provision for income taxes in the first quarter reflects an estimated annual effective tax rate of 30 percent compared to 29 percent for the first quarter of 2011 and 26.5 percent for the full-year 2011 excluding discrete items. The increase from full-year 2011 is primarily due to expected changes in our geographic mix of profits from a tax perspective and the expiration of the U.S. research and development tax credit.
