Commitments and Contingencies In July 2017, APTIM Corp. sued Allied and certain of its employees and affiliated entities in the U.S. District Court for the Northern District of Illinois, alleging, among other things, misappropriation of alleged trade secrets and civil conspiracy. APTIM also alleged tortious interference with their contractual and business relations because Exelon, our customer whose business makes up 100% of our nuclear services revenues, ended their business relationship with APTIM and started a new business relationship with Allied. The litigation was indefinitely stayed on June 21, 2018 pending resolution of the arbitration discussed in the next paragraph which has overlapping issues with this litigation. The parties were engaged in discovery relevant to APTIM's motion for preliminary injunction, which was filed last July, before the stay was entered. APTIM has an unspecified claim for damages that may proceed if the stay is lifted. No schedule for that phase of the case, and no trial date, has been set. APTIM has not identified its alleged damages. APTIM and its alleged predecessors in interest have also initiated judicial and arbitral proceedings in Louisiana against Dorsey Ron McCall, our Senior Vice President and Board Member. In June 2017, APTIMs alleged predecessor, The Shaw Group, Inc., sued Mr. McCall in Louisiana state court, alleging breaches of his employment agreement. APTIM later filed a petition in the U.S. District Court for the Eastern District of Louisiana seeking to stay the state-court litigation and compel arbitration of the breach-of-contract claims, which the district court granted, permitting APTIMs pending arbitration against Mr. McCall to proceed. Mr. McCall appealed that decision to the U.S. Court of Appeals for the Fifth Circuit, which affirmed the district courts order. Mr. McCall filed a petition for rehearing en banc on May 1, 2018 and the Fifth Circuit directed APTIM to file a response to the petition by May 24, 2018. On May 31, 2018, the Fifth Circuit denied Mr. McCalls petition. The matter has now proceeded to arbitration which has been set for March 11-22, 2019. McCall and APTIM each filed motions to dismiss certain claims asserted by the other. Each of those motions were denied on September 24, 2018 and October 24, 2018, respectively. The Company recently received an offer from APTIM to settle outstanding litigation, and is reviewing that proposal along with its insurance carrier. We are party to a lawsuit filed against North Carolina by a certain environmental advocacy group alleging that the issuance by the state of certain permits associated with our Brickhaven clay mine reclamation site exceeded the states power. Although the states authority to issue the bulk of the permits (i.e. the allowance to reclaim the original site with coal ash) was upheld, the portion of the permits that allows us to cut and prepare an additional portion of the site was held by the North Carolina Superior Court to exceed the relevant agencys statutory authority. The North Carolina Superior Courts decision was reversed and remanded back to the North Carolina Office of Administrative Hearing (OAH). If the OAH determines North Carolina exceeded its permitting authority with respect to either the original allowance or the cut and prepare portions of the permits or both, such decision, if ultimately upheld, could have an adverse effect on our operations and financial results. Allied, and its affiliate, Allied Power Resources, LLC, have been named in a collective action lawsuit filed in the U.S. District Court for the Northern District of Illinois, alleging violations of the Fair Labor Standards Act, and which includes related class claims alleging violations of the Illinois Minimum Wage Law and Pennsylvania Minimum Wage Act for failure to pay overtime. This case is one of a series filed against companies in the oil, gas, and energy industries in Illinois and Texas. The Plaintiffs have an unspecified claim for damages. The collective action class claims have not been certified and the case is currently stayed pending a mediation that is currently set for November 26, 2018. In addition to the above matters, we are from time to time party to various lawsuits, claims and other legal proceedings arising in the ordinary course of our business. While the outcome of such proceedings cannot be predicted with certainty, we do not expect them to have a material adverse impact on the Company. Included in general and administrative expense in the condensed consolidated statement of income for the quarter ended September 30, 2018, and in accrued liabilities in the condensed consolidated balance sheet as of September 30, 2018, was approximately $20.0 million in accruals related to outstanding legal matters. We believe that the amounts accrued are sufficient to cover any liabilities arising from the proceedings with APTIM and all other outstanding legal claims. Except as reflected in such accruals, we are currently unable to estimate a range of reasonably possible loss, or a range of reasonably possible loss in excess of the amount accrued, for outstanding legal matters.
