Accounting Policies [Abstract]

Basis of Presentation

The accompanying financial statements have been presented on a condensed consolidated basis for the “Successor” periods subsequent to the Asset Acquisition, which include the three and six months ended June 30, 2017, and on a condensed combined basis for the “Predecessor” periods prior to the Asset Acquisition, which includes the three months ended March 31, 2016. The financial information of the Company has been separated by a vertical line on the face of the financial statements to identify these different bases of accounting for Predecessor and Successor periods.

The accompanying financial statements are presented in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In our opinion the financial statements include all adjustments (consisting of normal recurring accruals) necessary in order to make the financial statements not misleading.

Cash and Cash Equivalents and Restricted Cash

Cash and cash equivalents include short-term deposits and highly liquid investments that have original maturities of three months or less when purchased and are stated at cost, which approximates fair value. As of June 30, 2017 (Successor) and December 31, 2016 (Successor), restricted cash included in other long-term assets in the Condensed Balance Sheet represents amounts funded to an escrow account as collateral for coal royalties due under certain underground coal mining lease contracts.

Short-Term Investments

Instruments with maturities greater than three months, but less than twelve months, are included in short-term investments. The Company purchases United States Treasury bills with maturities ranging from six to twelve months which are classified as held to maturity and are carried at amortized cost, which approximates fair value. Securities classified as held to maturity securities are those securities that management has the intent and ability to hold to maturity.

New Accounting Pronouncements

In September 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments,” which eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Instead, an acquirer will recognize a measurement-period adjustment during the period in which it determines the amount of the adjustment. The guidance is effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. We adopted the amendments of ASU 2015-16, effective January 1, 2017. We recognized a $3.5 million measurement-period adjustment during the three months ended March 31, 2017 (Successor), which we reflected prospectively (see Note 3). 

In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” which defers the effective date of ASU 2014-09 by one year. ASU 2015-14 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period and permits early adoption on a limited basis. ASU 2014-09, “Revenue from Contracts with Customers”, requires an entity to recognize revenue upon transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The Company is currently in the process of evaluating the impact of this new pronouncement on its consolidated results of operations. The Company plans to complete its assessment of the impact of the new standard in 2017 and expects to be compliant by the first quarter of 2018.
