Environmental Matters [Abstract] |
Environmental Costs, Policy [Policy Text Block] | Environmental Matters We are not aware of any potential unasserted environmental claims that may be brought against us. We are involved in environmental investigation and/or remediation at two of our plant sites no longer used for operations. We use environmental consultants to assist us in evaluating our environmental liabilities in order to establish appropriate accruals in our financial statements. Accruals are recorded when environmental remediation is probable and the costs can be reasonably estimated. A number of factors affect the cost of environmental remediation, including the determination of the extent of contamination, the length of time remediation may require, the complexity of environmental regulations and the advancement of remediation technology. Considering these factors, we have estimated (without discounting) the costs of remediation, which will be incurred over a period of several years. Recovery from insurance or other third parties is not anticipated. We are not yet able to determine when such remediation activity will be complete, but estimates for certain remediation efforts are projected through fiscal 2015. At April 28, 2012 and April 30, 2011, we had accruals, primarily based upon independent engineering studies, for environmental matters of $2,881 and $4,669, respectively, of which $500 was classified in other accrued expenses and the remainder was included in other long-term liabilities on our consolidated balance sheet. We believe the provisions made for environmental matters are adequate to satisfy liabilities relating to such matters, however it is reasonably possible that costs could exceed accrued amounts if the selected methods of remediation do not reduce the contaminates at the sites to levels acceptable to federal and state regulatory agencies. In fiscal 2012, we spent $1,501 on remediation cleanups and related studies compared with $527 in fiscal 2011 and $474 in fiscal 2010. The costs associated with environmental matters as they relate to day-to-day activities were not material in fiscal 2012, 2011 or 2010.

- Definition Disclosure of accounting policy for obligations that resulted from improper or other-than normal operation of a long-lived asset in the past. This accounting policy may address (1) whether the related remediation costs are expensed or capitalized, (2) whether the obligation is measured on a discounted basis, (3) the event, situation, or set of circumstances that generally triggers recognition of loss contingencies arising from the entity's environmental remediation-related obligations, and (4) the timing of recognition of any recoveries. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 410 -SubTopic 30 -URI http://asc.fasb.org/subtopic&trid=2175709 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Emerging Issues Task Force (EITF) -Number 89-13 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
