Income Taxes [Abstract]
Income Taxes	Note 13 — Income Taxes The Corporation’s provision for income taxes in interim periods is computed by applying its estimated annual effective tax rate against income before income tax expense for the period.

During the prior year quarter, the Corporation recognized the deferred tax effects of the reduced deductibility of the postretirement prescription drug coverage due to the enacted U.S. Patient Protection and Affordable Care Act, which increased the Corporation’s income tax expense by $1.6 million. At February 28, 2011, the Corporation had unrecognized tax benefits of $43.3 million that, if recognized, would have a favorable effect on the Corporation’s income tax expense of $32.8 million.

The Corporation is subject to examination by the U.S. Internal Revenue Service and various U.S. state and local jurisdictions for tax years 1996 to the present. The Corporation is also subject to tax examination in various international tax jurisdictions, including Canada, the United Kingdom, Australia, France, Italy, Mexico and New Zealand for tax years 2006 to the present.

Note 13 — Income Taxes

The Corporation’s provision for income taxes in interim periods is computed by applying its estimated annual effective tax rate against income before income tax expense for the period. In addition, non-recurring or discrete items are recorded during the period in which they occur. The magnitude of the impact that discrete items have on the Corporation’s quarterly effective tax rate is dependent on the level of income in the period. The effective tax rate was 35.8% and 39.6% for the three month periods ended May 27, 2011 and May 28, 2010, respectively. During the prior year quarter, the Corporation recognized the deferred tax effects of the reduced deductibility of the postretirement prescription drug coverage due to the enacted U.S. Patient Protection and Affordable Care Act, which increased the Corporation’s income tax expense by $1.6 million.

At February 28, 2011, the Corporation had unrecognized tax benefits of $43.3 million that, if recognized, would have a favorable effect on the Corporation’s income tax expense of $32.8 million. There were no significant changes to this amount during the first quarter of 2012. It is reasonably possible that the Corporation’s unrecognized tax positions as of February 28, 2011 could decrease approximately $9.5 million during the next twelve months due to anticipated settlements and resulting cash payments related to open years after 1996, which are currently under examination.

The Corporation recognizes interest and penalties accrued on unrecognized tax benefits and refundable income taxes as a component of income tax expense. During the first quarter of 2012, the Corporation recognized net expense of $0.5 million for interest and penalties on unrecognized tax benefits and refundable income taxes. As of May 27, 2011, the total amount of gross accrued interest and penalties related to unrecognized tax benefits less refundable income taxes was a net payable of $16.9 million.

The Corporation is subject to examination by the U.S. Internal Revenue Service and various U.S. state and local jurisdictions for tax years 1996 to the present. The Corporation is also subject to tax examination in various international tax jurisdictions, including Canada, the United Kingdom, Australia, France, Italy, Mexico and New Zealand for tax years 2006 to the present.
