Contingent Liability [Abstract]
Legal Matters and Contingencies [Text Block]	Contingent Liabilities In 2012, the Company identified that a site it owns in Decatur, Alabama contains hazardous substances in the soil and groundwater as a result of historical operations prior to the Company's ownership. The Company has retained an environmental consulting firm to further investigate the contamination including the measurement and monitoring of the site. In August 2013, the site was enrolled in Alabama's voluntary cleanup program. On October 30, 2014, the Company received estimates from its environmental consulting firm with three potential remediation solutions. The estimates include a range of viable remedial approaches, but agreement with Alabama’s voluntary cleanup program has not yet been reached. The first solution includes limited excavation and removal of the contaminated soil along with monitoring for a period up to 10 years. The second solution includes the first solution plus the installation of a groundwater extraction system. The third scenario includes the first and second solutions plus treatment injections to reduce the degradation time. The estimated expenditures over a 10-year period under the three scenarios range from $0.3 million to $1.4 million, of which up to $0.3 million may be capitalized. As the Company has determined that a loss is probable, however no scenario is more likely than the other at this time, a liability in the amount of $0.3 million was established in 2014. As of June 30, 2015, approximately $0.2 million remains accrued for remediation in other long-term liabilities on the accompanying consolidated balance sheet.
