Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies Disclosure [Text Block] | 10. Commitments and Contingencies In the ordinary course of business, the Company is subject to various claims and legal proceedings, workers’ compensation and product liability disputes. The Company is of the opinion that the ultimate resolution of these matters will not have a material adverse affect on the results of operations, cash flows or the financial position of the Company. As a result of environmental studies performed at the Company’s former facility located in Sarasota, Florida, the Company became aware of soil and groundwater contamination at the Company site. The Company engaged an environmental engineering consultant to assess the level of contamination and to develop a remediation and monitoring plan for the site. Soil remediation at the site was completed during the year ended December 31, 2010. Ground water remediation at the site is expected to begin during the third quarter of 2013, upon approval of a remedial action plan. During the years ended December 31, 2012 and 2011, environmental remediation costs incurred were immaterial. At December 31, 2012 and 2011, the Company had accrued an undiscounted liability of $1,340 and $1,921, respectively, related to future remediation. At December 31, 2012 and 2011, $733 and $0, respectively, were recorded as a component of accrued expenses and other current liabilities on the consolidated balance sheets while the remaining amounts were recorded as a component of other long-term liabilities. A majority of the costs associated with the recorded liability will be incurred at the start of the groundwater remediation, with the balance relating to monitoring costs to be incurred over multiple years. The recorded liability is based on assumptions of the proposed remedial action plan. In December 2011, the Company sold the Sarasota facility and related property. However, the liability to remediate the site contamination remains the responsibility of the Company. Due to the ongoing site remediation, the closing terms of the sale agreement included a requirement for the Company to maintain a $2,000 letter of credit for the benefit of the buyer. In addition, PST has civil, labor and tributary contingencies for which the likelihood of loss is deemed to be reasonably possible, but not probable, by its legal advisors, and, therefore, no accrual was recorded. Such contingencies amount to $11,925 and $13,349 at December, 2012 and 2011, respectively.
