Summary of Significant Accounting Policies [Abstract] |
Basis of Presentation and Consolidation | Basis of Presentation and Consolidation ﻿ The condensed consolidated financial statements include the accounts of Hallador Energy Company (hereinafter known as, “we, us, or our”) and its wholly-owned subsidiaries Sunrise Coal, LLC (Sunrise) and Hourglass Sands, LLC (Hourglass), and Sunrise’s wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. Sunrise is engaged in the production of steam coal from mines located in western Indiana. Hourglass is in the development stage and is engaged in the production of frac sand in the State of Colorado (see Note 15).
Segment Information | Segment Information ﻿ The Company’s significant operating segments include the Oaktown and Carlisle underground mines located in southwestern Indiana. The Company’s chief operating decision maker (“CODM”) reviews the operating results, assesses performance and makes decisions about allocation of resources to these segments at the mine level, however, we aggregate the results of operations of the mines for reporting purposes since the nature of the product, production process, customer type, product distribution, and long-term economic characteristics at each location are similar.
Allowance for Doubtful Accounts | Allowance for Doubtful Accounts ﻿ The Company evaluates the need for an allowance for uncollectible receivables based on a review of account balances that are likely to be uncollectible, as determined by such variables as customer creditworthiness, the age of the receivables and disputed amounts. Historically, credit losses have been insignificant. At December 31, 2018 and 2017, no allowance was recorded for uncollectible accounts receivable as all amounts were deemed collectible.
Inventory | Inventory ﻿ Inventory and parts and supplies are valued at the lower of average cost or net realizable value. Inventory costs include labor, supplies, operating overhead, and other related costs incurred at or on behalf of the mining location, including depreciation, depletion, and amortization of equipment, buildings, mineral rights, and mine development costs.
Prepaid Expense | Prepaid expenses ﻿ Prepaid expenses include prepaid insurance, prepaid maintenance expense, and a prepaid balance with our primary parts and supplies vendor.
Advance Royalties | Advance Royalties ﻿ Coal leases that require minimum annual or advance payments and are recoverable from future production are generally deferred and charged to expense as the coal is subsequently produced. Advance royalties are included in other assets.
Mining Properties | Mining Properties ﻿ Mining properties are recorded at cost. Interest costs applicable to major asset additions are capitalized during the construction period. Expenditures that extend the useful lives or increase the productivity of the assets are capitalized. The cost of maintenance and repairs that do not extend the useful lives or increase the productivity of the assets are expensed as incurred. Other than land and most mining equipment, mining properties are depreciated using the units-of-production method over the estimated recoverable reserves. Most surface and underground mining equipment is depreciated using estimated useful lives ranging from three to twenty-five years. ﻿ If facts and circumstances suggest that a long-lived asset may be impaired, the carrying value is reviewed for recoverability. If this review indicates that the carrying value of the asset will not be recoverable through estimated undiscounted future net cash flows related to the asset over its remaining life, then an impairment loss is recognized by reducing the carrying value of the asset to its estimated fair value. See Note 2 for further discussion of impairments.
Mine Development | Mine Development ﻿ Costs of developing new mines, including asset retirement obligation assets, or significantly expanding the capacity of existing mines, are capitalized and amortized using the units-of-production method over estimated recoverable reserves.
Asset Retirement Obligations (ARO) - Reclamation | Asset Retirement Obligations (ARO) – Reclamation ﻿ At the time they are incurred, legal obligations associated with the retirement of long-lived assets are reflected at their estimated fair value, with a corresponding charge to mine development. Obligations are typically incurred when we commence development of underground and surface mines and include reclamation of support facilities, refuse areas and slurry ponds. ﻿ Obligations are reflected at the present value of their future cash flows. We reflect accretion of the obligations for the period from the date they are incurred through the date they are extinguished. The ARO assets are amortized using the units-of-production method over estimated recoverable (proved and probable) reserves. We are using discount rates ranging from 5.0% to 10%. Federal and state laws require that mines be reclaimed in accordance with specific standards and approved reclamation plans, as outlined in mining permits. Activities include reclamation of pit and support acreage at surface mines, sealing portals at underground mines, and reclamation of refuse areas and slurry ponds. ﻿ We review our ARO at least annually and reflect revisions for permit changes, changes in our estimated reclamation costs and changes in the estimated timing of such costs. In the event we are not able to perform reclamation, we have surety bonds totaling $26 million to cover ARO. ﻿ The table below (in thousands) reflects the changes to our ARO:

﻿
Statement of Cash Flows | Statement of Cash Flows ﻿ Cash equivalents include investments with maturities when purchased of three months or less.
Income Taxes | Income Taxes ﻿ Income taxes are provided based on the liability method of accounting. The provision for income taxes is based on pretax financial income. Deferred tax assets and liabilities are recognized for the future expected tax consequences of temporary differences between income tax and financial reporting and principally relate to differences in the tax basis of assets and liabilities and their reported amounts, using enacted tax rates in effect for the year in which differences are expected to reverse.
Net Income per Share | Net Income per Share ﻿ Basic net income per share is computed on the basis of the weighted average number of shares of common stock outstanding during the period using the two-class method for our common shares and RSUs which share in the Company’s earnings. Diluted net income per share is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period. Dilutive potential common shares include restricted stock units and are included in basic net income per share, using the two-class method.
Use of Estimates in the Preparation of Financial Statements | Use of Estimates in the Preparation of Financial Statements ﻿ The preparation of financial statements in conformity with generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual amounts could differ from those estimates. The most significant estimates included in the preparation of the financial statements relate to: (i) deferred income tax accounts, (ii) coal reserves, (iii) depreciation, depletion, and amortization, (iv) estimates relating to interest rate swaps, and (v) estimates used in our impairment analysis. ﻿
Long-term Contracts | Long-term Contracts ﻿ As of December 31, 2018, we are committed to supplying our customers up to a maximum of 30.5 million tons of coal through 2024 of which 20.7 million tons are priced. ﻿ For 2018, we derived 82% of our coal sales from four customers, each representing at least 10% of our coal sales. 77% of our accounts receivable were from five customers, each representing more than 10% of the December 31, 2018 balance. ﻿ For 2017, we derived 92% of our coal sales from five customers, each representing at least 10% of our coal sales. 83% of our accounts receivable were from four of these customers, each representing more than 10% of the December 31, 2017 balance. ﻿
Stock-based Compensation | ﻿ Stock-based Compensation ﻿ Stock-based compensation is measured at the grant date based on the fair value of the award and is recognized as expense over the applicable vesting period of the stock award (generally two to four years) using the straight-line method. ﻿
New Accounting Pronouncements | New Accounting Standards Issued and Adopted ﻿ IIn May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 is a comprehensive revenue recognition standard that supersedes nearly all existing revenue recognition guidance under current U.S. GAAP and replaces it with a principle-based approach for determining revenue recognition. On January 1, 2018, we adopted the new accounting standard and all of the related amendments to all contracts using the modified retrospective method. Adoption of the new revenue standard did not result in a material cumulative effect adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. We do not expect the adoption of the new revenue standard to have a material impact to our net income on an ongoing basis, however we recognized revenue of $0.5 million over the course of the year related to MSHA costs that would have been recognized in a future period under the old standard. See “Note 14 - Revenue” to these consolidated financial statements for additional disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 requires equity investments that are not accounted for under the equity method of accounting or that do not result in consolidation of the investee to be measured at fair value with changes recognized in net earnings. ASU 2016-01 also eliminates the available-for-sale classification for equity investments that recognized changes in fair value as a component of other comprehensive income. We adopted ASU 2016-01 on January 1, 2018, using the modified retrospective method, which resulted in a $1.1 million (net of tax) cumulative-effect adjustment from accumulated other comprehensive income to retained earnings. Adoption of ASU 2016-01 did not have a material impact on our results of operations and/or cash flows. In November 2016, the FASB issued guidance regarding the presentation of restricted cash in the statement of cash flows (ASU 2016-18). This update is effective for annual reporting periods beginning after December 15, 2017, and early adoption is permitted. We have adopted the new standard as of January 1, 2018. Adoption of ASU 2016-18 did not have a material impact on the company’s results of operations and/or cash flows. In January 2017, the FASB issued new guidance to assist in determining if a set of assets and activities being acquired or sold is a business (ASU 2017-01). It also provided a framework to assist entities in evaluating whether both an input and a substantive process are present, which at a minimum, must be present to be considered a business. We have adopted the new standard as of January 1, 2018. The standard does not have an impact on our historical recognition of asset acquisitions and business combinations. However, we expect there may be an impact on how we account for such acquisitions in the future. In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018-02 allows companies to reclassify stranded tax effects resulting from the 2017 Tax Act from accumulated other comprehensive income to retained earnings. The company elected to early adopt ASU 2018-02 on January 1, 2018, which resulted in a reclassification of $192,000 of stranded tax effects, related to our unrealized gain on marketable securities, from accumulated other comprehensive income to retained earnings. Adoption of ASU 2018-02 did not have a material impact on our results of operations and/or cash flows. ﻿ ﻿ New Accounting Standards Issued and Not Yet Adopted ﻿ IIn February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (ASU 2016-02). ASU 2016-02 increases transparency and comparability among organizations by requiring lessees to record right-to-use assets and corresponding lease liabilities on the balance sheet and disclosing key information about lease arrangements. The new guidance will classify leases as either finance or operating (similar to current standard’s “capital” or “operating” classification), with classification affecting the pattern of income recognition in the statement of income. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The FASB continues to issue clarifications, updates and implementation guidance to ASU 2016-02 which we continue to monitor, such as ASU 2018-01, Leases (Topic 842) ("ASU 2018-01") and ASU 2018-11, Leases (Topic 842) ("ASU 2018-11") which provides practical expedients for transition to Topic 842. ASU 2018-01 allows for companies that did not previously recognize land easements as leases to continue this practice for existing leases but will still require the evaluation of new lease arrangements, including land easements. ASU 2018-11 provides an option to apply the transition provisions of the new standard at its adoption date instead of at the earliest comparative period presented and permits lessors to not separate non-lease components from the associated lease component if certain conditions are met. We will elect to apply this option at the adoption date. ﻿ We have completed our review of our current population of leases and continue our efforts to update the population for new leases. We have also developed internal controls and systems for our implementation and ongoing accounting for leases. We will recognize lease liabilities and offsetting right-of-use assets of approximately $0.5 million in our consolidated balance sheets for operating leases upon adoption on January 1, 2019. ﻿
Subsequent Events | Subsequent Events ﻿ In January 2019, we declared a dividend of $.04 per share to shareholders of record as of January 31, 2019. The dividend was paid on February 15, 2019. ﻿ In January 2019, we sold our overriding royalty interests in certain producing oil properties in Southern Wyoming for $2.5 million and recognized a gain for the same amount.
