The tax rate for the nine months ended March 31, 2012 and 2011 was 33% and 29%, respectively. The difference in the rates is primarily due to a full-year benefit of federal research and development tax credit in fiscal 2011 compared to only a six-month benefit in fiscal 2012. The effective tax rate for nine months ended March 31, 2012 and 2011 differed from the federal statutory rate primarily due to the impact of research and development tax credits and the impact of a Section 199 Manufacturing Deduction.
