Other Noncurrent Assets And Liabilities [Abstract]
Other Noncurrent Assets And Liabilities	NOTE 10: OTHER NONCURRENT ASSETS AND LIABILITIES We have deferred compensation plans that permit certain employees to defer portions of their compensation and accrue income on the deferred amounts. Included in other noncurrent liabilities is $48.0 million and $142.0 million at April 30, 2012 and 2011, respectively, reflecting our obligation under these plans. The decline in the liability from the prior year is primarily due to amounts paid to former employees in connection with the sale of RSM. We purchased whole-life insurance contracts on certain participants to recover distributions made or to be made under these plans. The cash surrender value of the policies and other assets totaled $99.0 million and $105.0 million at April 30, 2012 and 2011, respectively. These assets are restricted, as they are only available to fund the related liabilities. Due to our plan to liquidate certain of these investments, at April 30, 2012, $81.4 million of these assets were classified as current and included in prepaid and other current assets on the consolidated balance sheet. The remaining balance as of April 30, 2012, and the entire balance as of April 30, 2011, was included in other noncurrent assets on the consolidated balance sheets.
