Commitments And Contingencies [Abstract] |
Commitments And Contingencies | N. COMMITMENTS AND CONTINGENCIES In the ordinary course of its business operations, the Company enters into arrangements that obligate it to make future payments under contracts such as lease agreements. Additionally, the Company is involved, from time to time, in commercial litigation, employment disputes, administrative proceedings, business disputes and other legal proceedings. The Company has established accruals for certain proceedings based on an assessment of probability of loss. The Company believes that any potential loss in excess of the amounts accrued would not have a material effect on the business or its consolidated financial statements. Such proceedings are exclusive of environmental remediation matters which are discussed separately below. Environmental Remediation In 1992, the Company entered into a consent decree with the U.S. Environmental Protection Agency (the “EPA”) in which the Company committed to remediate environmental contamination of the groundwater that was discovered in 1982 through 1990 at and adjacent to its Lindsay, Nebraska facility (the “site”). The site was added to the EPA’s list of priority superfund sites in 1989. Between 1993 and 1995, remediation plans for the site were approved by the EPA and fully implemented by the Company. Since 1998, the primary remaining contamination at the site has been the presence of volatile organic compounds in the soil and groundwater. To date, the remediation process has consisted primarily of drilling wells into the aquifer and pumping water to the surface to allow these contaminants to be removed by aeration. In fiscal 2012, the Company undertook an investigation to assess further potential site remediation and containment actions. In connection with the receipt of preliminary results of this investigation and other evaluations, the Company estimated that it would incur $7.2 million in remediation of source area contamination and operating costs and accrued that undiscounted amount. The EPA has not approved the Company’s remediation plan. In addition to the source area noted above, the Company has determined that volatile organic compounds also exist under one of the manufacturing buildings on the site. Due to the location, the Company has not yet determined the extent of these compounds or the extent to which they are contributing to groundwater contamination. Based on the current stage of discussions with the EPA and the uncertainty of the remediation actions that may be required with respect to this affected area, if any, the Company believes that meaningful estimates of costs or range of costs cannot currently be made and accordingly have not been accrued. In fiscal 2013, the Company and the EPA conducted a periodic five-year review of the status of the remediation of the contamination of the site. During a meeting with the EPA in December 2014, the EPA requested that the Company prepare a feasibility study related to the site, which resulted in a revision to the Company’s remediation timeline. In November 2014, the Company accrued $1.5 million of incremental operating costs to reflect its updated timeline of when an approved remediation plan could begin. The Company now intends to perform its investigation of the soil and groundwater on the site during the first half of calendar 2016. In connection with the development of the feasibility study, the Company will assess revisions to its remediation plan and expects to meet with the EPA toward the end of calendar 2016 to determine how to proceed. The Company accrues the anticipated cost of investigation and remediation when the obligation is probable and can be reasonably estimated. Although the Company has accrued all reasonably estimable costs associated with the site, it anticipates there could be revisions to the current remediation plan as well as additional testing and environmental monitoring as part of the Company’s ongoing discussions with the EPA regarding the development and implementation of the remedial action plans. While a ny revisions could be material to the operating results of any f iscal quarter or fiscal year, t he Company does not expect such additional expenses would have a material adverse effect on its liquidity or financial condition. The following table summarizes the undiscounted environmental remediation liability classifications included in the balance sheet as of August 31, 2015 and 2014:
Environmental Remediation Liabilities
