Commitments and Contingencies

The Company accrues for cost related to contingencies when a loss is probable and the amount is reasonably determinable. Disclosure of contingencies is included in the financial statements when it is at least reasonably possible that a material loss or an additional material loss in excess of amounts already accrued may be incurred.
 
The Company is a party to numerous claims and lawsuits with respect to various matters. As of December 31, 2017 and 2016, the Company had accrued $0.2 million and $2.2 million, respectively, for all legal matters, including $0.2 million and $2.2 million, respectively, classified as current.  The ultimate resolution of any such legal matter could result in outcomes which may be materially different from amounts the Company has accrued for such matters.

 The Company has unconditional purchase obligations relating to purchases of coal, materials and supplies and capital commitments, other than reserve acquisitions, and is also a party to transportation capacity commitments. The future commitments under these agreements total $97.2 million in 2018, and is immaterial thereafter. The Company recognized expense relating to transportation capacity agreements of $1.6 million during the period January 1 through October 1, 2016; and $52.9 million during the year ended December 31, 2015, respectively.
