5. Income Taxes

The effective tax rate for the first quarter of 2012 and 2011 was 41.9 percent and 39.3 percent, respectively. The effective tax rates for the first quarter of fiscal 2012 and 2011 are higher than the statutory rate due primarily to the impact of non-deductible expenses related to post-retirement benefit costs.
