Income Tax Policy [Abstract]
Taxes	7. Taxes The combined federal and state income tax rates were 32.3% in the second quarter of fiscal 2013 versus 34.1% in the corresponding period a year ago. The lower tax rate for the second quarter of fiscal 2013 resulted from favorable tax settlements with certain taxing authorities. Our effective income tax rate is evaluated each quarter. The effective income tax rate for the quarter may or may not represent the expected annual effective tax rate for the entire fiscal year and includes the impact of discrete items for the quarter. We expect the annual effective tax rate for fiscal 2013 to be in a range of 33.5% to 34.5%.
