Intangible Contract Assets and Liabilities Disclosure [Abstract] |
Intangible Assets and Liabilities [Text Block] | Intangible Contract Assets and Liabilities As described in Note 2. “Emergence from the Chapter 11 Cases and Fresh Start Reporting,” and Note 3. “Acquisition of Shoal Creek Mine,” the Company has recorded intangible assets and liabilities to reflect the fair value of certain U.S. coal supply agreements as a result of differences between contract terms and estimated market terms for the same coal products, and also recorded intangible liabilities related to unutilized capacity under its port and rail take-or-pay contracts. The balances, net of accumulated amortization, and respective balance sheet classifications at December 31, 2018 and 2017, are set forth in the following tables:

Amortization of the intangible assets and liabilities related to coal supply agreements occurs ratably based upon coal volumes shipped per contract and is recorded as a component of “Depreciation, depletion and amortization” in the accompanying consolidated statements of operations. Such amortization amounted to net expense of $93.0 million and $121.3 million during the year ended December 31, 2018 and the period April 2 through December 31, 2017, respectively. The Company anticipates net amortization of sales contracts, based upon expected shipments in the next five years, to be an expense of approximately $27 million, $8 million, $3 million, $1 million and $1 million for the years 2019 through 2023, respectively. Future unutilized capacity and the amortization periods related to the take-or-pay contract intangible liabilities are based upon estimates of forecasted usage. Such amortization, which is classified as a reduction to “Operating costs and expenses” in the accompanying consolidated statements of operations, amounted to $26.6 million and $22.5 million during the year ended December 31, 2018 and the period April 2 through December 31, 2017, respectively. The Company anticipates net amortization of take-or-pay contract intangible liabilities to be approximately $17 million, $9 million, $4 million, $3 million and $3 million for the years 2019 through 2023, respectively, and $21 million thereafter.
