Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	RELATED PARTY TRANSACTIONSAs noted in previous filings, DCI, a former affiliate of the Company, was named a party to several lawsuits in 1999 and 2000 regarding the activities of DCI while it was an operating subsidiary of an affiliate of the Company. The Company was named a party to several of the lawsuits (the “DCI Litigation”) due to its affiliation with DCI. In December 2000, the Company and DCI entered into a Litigation Cost Sharing Agreement (the “Agreement”) whereby the Company agreed to advance DCI's portion of the costs of defending against the DCI Litigation. As discussed in Note 1, certain plaintiffs are seeking to enforce the DCI judgment against the Company under various legal theories including pursuant to the Agreement. The Company's advances to cover DCI's costs for the DCI Litigation during the years ended December 31, 2020, 2019, and 2018 were $0, $63, and $307, respectively, not including interest. As of December 31, 2020, the Company has a receivable on its consolidated balance sheet of $15,961 for advances made in connection with the DCI Litigation and amounts due, including interest, under the Agreement, which has been fully reserved for collectability by the Company because DCI does not currently have any assets. DCI is currently wholly owned by an unaffiliated company whose sole shareholder is an executive of the Company..
