Legal Matters and Contingencies [Text Block]	(14) Contingencies Legal proceedings. On November 19, 2007, Dywidag Systems International, Inc. (“DSI”) filed a third-party lawsuit in the Ohio Court of Claims alleging that certain epoxy-coated strand sold by the Company to DSI in 2002, and supplied by DSI to the Ohio Department of Transportation (“ODOT”) for a bridge project, was defective. The third-party action sought recovery of any damages which could have been assessed against DSI in the action filed against it by ODOT, which allegedly could have been in excess of $8.3 million, plus $2.7 million in damages allegedly incurred by DSI. In 2009, the Ohio court granted the Company’s motion for summary judgment as to the third-party claim against it on the grounds that the statute of limitations had expired, but DSI filed an interlocutory appeal of that ruling. In addition, the Company previously filed a lawsuit against DSI in the North Carolina Superior Court in Surry County seeking recovery of $1.4 million (plus interest) owed for other products sold by the Company to DSI, which action was removed by DSI to the U.S. District Court for the Middle District of North Carolina. On October 7, 2010, the Company participated in a structured mediation with ODOT and DSI which led to settlement of all of the above legal matters. The parties dismissed the action in the Middle District of North Carolina on December 23, 2010, and the Ohio Court of Claims action was dismissed on January 21, 2011. Pursuant to the settlement agreement, which was approved by the Ohio Court of Claims on January 5, 2011, the parties released each other from all liability arising out of the sale of strand for the bridge project. In connection with the settlement, the Company reserved the remaining outstanding balance that it was owed by DSI and agreed to make a cash payment of $600,000 to ODOT. During the second quarter of 2011, the Company paid the $600,000 settlement to ODOT and wrote off the DSI receivables against the previously established reserve. The resolution of this matter has enabled the Company to reinstate its commercial relationship with DSI that had existed prior to the initiation of the legal proceedings. The Company is involved in other lawsuits, claims, investigations and proceedings, including commercial, environmental and employment matters, which arise in the ordinary course of business. The Company does not expect that the ultimate costs to resolve these matters will have a material adverse effect on its financial position, results of operations or cash flows.
