The effective tax rate for the six months ended December 31, 2011 and 2010 was 34% and 30%, respectively. The difference in the rates is primarily due to a full-year benefit of federal research and development tax credit in fiscal 2011compared to only a six-month benefit in fiscal 2012. The effective tax rate for six months ended December 31, 2011 and 2010 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.
