Income Taxes [Abstract]
Income Taxes	Note K — Income Taxes Our effective tax rate (income taxes as a percentage of income before income taxes) was 34.2 percent in the second quarter of fiscal 2012 compared with 31.9 percent in the second quarter of fiscal 2011. In the second quarter of fiscal 2011, our effective tax rate benefited from a $5.9 million tax benefit associated with legislative action during the second quarter of fiscal 2011 that restored the U.S. Federal income tax credit for research and development expenses. Our effective tax rate was 32.8 percent in the first two quarters of fiscal 2012 compared with 33.5 percent in the first two quarters of fiscal 2011. In the first two quarters of fiscal 2012, our effective tax rate benefited from a reduction in state taxes due to changes in certain state tax laws and a reduction in estimated tax liabilities. In the first two quarters of fiscal 2011, the major discrete item was the same as that noted above regarding the second quarter of fiscal 2011.
