Accounting Policies [Abstract] |
Consolidation, Policy [Policy Text Block] | Basis of Presentation and Consolidation The consolidated financial statements include the accounts of Hallador Energy Company and its wholly-owned subsidiary Sunrise Coal, LLC (Sunrise). All significant intercompany accounts and transactions have been eliminated. We are engaged in the production of steam coal from mines located in western Indiana. We own a 45% equity interest in Savoy Energy L.P., a private oil and gas company which has operations in Michigan and a 50% interest in Sunrise Energy LLC, a private entity engaged primarily in natgas operations in the same vicinity as the Carlisle mine.
Reclassification, Policy [Policy Text Block] | Reclassification To maintain consistency and comparability, certain amounts in the 2012 financial statements have been reclassified to conform to current year presentation.
Inventory Supplies, Policy [Policy Text Block] | Inventories Coal and supplies inventories are valued at the lower of average cost or market. Coal inventory costs include labor, supplies, equipment costs and overhead.
Revenue Recognition, Services, Royalty Fees [Policy Text Block] | 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.
Coal Properties | Coal Properties Coal 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 underground mining equipment, coal properties are depreciated using the units-of-production method over the estimated recoverable reserves. Surface and underground mining equipment is depreciated using estimated useful lives ranging from five to twenty 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.
Mine Development | Mine Development Costs of developing new coal 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 (proved and probable) reserves.
Asset Retirement Obligations, Policy [Policy Text Block] | 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 asset retirement obligation assets are amortized using the units-of-production method over estimated recoverable (proved and probable) reserves. We are using a 5.5% discount rate. 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 assess 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. The table below (in thousands) reflects the changes to our ARO:
|  | 2013 |  |  | 2012 |
Balance beginning of year |  | $ | 2,573 |  |  | $ | 2,276 |
Accretion |  |  | 182 |  |  |  | 138 |
Additions – primarily Ace for 2013 |  |  | 2,535 |  |  |  | 159 |
Balance end of year |  | $ | 5,290 |  |  | $ | 2,573 |
Statement of Cash Flows Policy | Statement of Cash Flows Cash equivalents include investments with maturities when purchased of three months or less.
Income Tax, Policy [Policy Text Block] | 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.
Earnings Per Share, Policy [Policy Text Block] | Earnings per Share Basic earnings per share are computed on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share are 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 using the treasury stock method. Dilutive potential common shares include restricted stock units.
Use of Estimates, Policy [Policy Text Block] | 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 are related to deferred income tax assets and liabilities and coal reserves.
Revenue Recognition, Sales of Goods [Policy Text Block] | Revenue Recognition We recognize revenue from coal sales at the time risk of loss passes to the customer at contracted amounts and amounts are deemed collectible.
Long-Duration Contracts, Policy [Policy Text Block] | Long-term Contracts We evaluate each of our contracts to determine whether they meet the definition of a derivative and they do not. As of December 31, 2013, we are committed to supply to our customers 5.8 million tons of coal during the next three years. During 2013 four of our customers accounted for 94% of our coal sales: one for 39%, the second for 29%, the third for 14% and the fourth for 12%. During 2012 three of our customers accounted for 93% of our coal sales: one for 46%, the second for 31%, and the third for 16%. We are paid every two to four weeks and do not expect any credit losses.
Employee Stock Ownership Plan (ESOP), Policy [Policy Text Block] | 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 three to four years) using the straight-line method.
New Accounting Pronouncements, Policy [Policy Text Block] | New Accounting Pronouncements None of the recent FASB pronouncements will have any material effect on us.
Subsequent Events, Policy [Policy Text Block] | Subsequent Events We have evaluated all subsequent events through the date the financial statements were issued. No material recognized or non-recognizable subsequent events were identified.
