12. Contingencies In January 2016, WPP sent a demand letter to Macoupin claiming it had misapplied the royalty recoupment provision involving a coal mining lease and a rail infrastructure lease, resulting in underpayments of $3.3 million. In April 2016, WPP and HOD filed a complaint in the Circuit Court of Macoupin County, Illinois. We do not believe that the royalty recoupment provision was misapplied and have continued to apply the recoupment provision consistently with prior periods. While we believe that the language of the agreements and the parties course of performance thereunder support Macoupins position, should we not prevail, we would be responsible for paying WPP for any recoupment taken that is found to contravene the contractual language. In July 2015, we provided notice to WPP, a subsidiary of NRP, declaring a force majeure event at our Hillsboro mine due to a combustion event. As a result of the force majeure event, as of June 30, 2017, we have not made $61.0 million in minimum deficiency payments to WPP in accordance with the force majeure provisions of the royalty agreement. On November 24, 2015, WPP filed a Complaint in the Circuit Court of Montgomery County, Illinois, against Hillsboro. After we prevailed on various motions to dismiss the Complaint, as well as the First and Second Amended Complaints, WPP filed its Third Amended Complaint on January 16, 2017. In the Third Amended Complaint, WPP alleges that (i) the stoppage of mining operations as a result of the spontaneous combustion event does not constitute an event of force majeure under the royalty agreement, (ii) Hillsboros reliance on the force majeure language is a breach of the royalty agreement, and (iii) that Hillsboros failure to recommence mining is a further breach of the royalty agreement. Hillsboro denies each of these allegations. In addition, WPP, in the Third Amended Complaint, names Foresight Energy GP, LLC; Foresight Energy, LP; Foresight Energy, LLC; Foresight Energy Services, LLC; Coal Field Construction Company, LLC
