Summary of Significant Accounting Policies (Textual)
Number of consolidated partnerships | Partnership							47
Cost method investments, additional information							The cost method of accounting is generally used for investments in affiliates in which we have less than 20% of the voting interests of a corporate affiliate (or less than a 3% to 5% interest of a partnership or limited liability company) and do not have significant influence.
Equity method investment, additional information							If we hold between 20% and 50% of the voting interest in non-consolidated corporate affiliates or generally greater than a 3% to 5% interest of a partnership or limited liability company and can exert significant influence or control (e.g., through our influence with a seat on the board of directors or management of operations), the equity method of accounting is generally used to account for the investment. Equity method investments will increase or decrease by our share of the affiliate's profits or losses and such profits or losses are recognized in our unaudited consolidated statements of operations. For our equity method investment in Carbon Appalachia, we use the hypothetical liquidation at book value method to recognize our share of the affiliate's profits or losses.
