Impairment of Assets [Abstract] |
Asset Impairment Charges [Text Block] | Impairment of Assets In August 2011, Enogex recorded a pre-tax impairment loss related to its Atoka joint venture which operated a 20 MMcf/d refrigeration processing plant which processed gas gathered in the Atoka, OK area. The processing plant was leased on a month-to-month basis. In August 2011, management made a decision to use third-party processing exclusively for gathered volumes dedicated to Atoka and, therefore, to take the processing plant out of service and return it to the lessor in accordance with the rental agreement. As a result Enogex recorded a pre-tax impairment loss of $5.0 million associated with the cost it had capitalized in connection with the installation of the leased plant as those costs were determined to be not recoverable through future cash flows. The noncontrolling interest portion of the pre-tax impairment loss was $2.5 million which was included in Net Income Attributable to Noncontrolling Interests in the Company's Consolidated Statement of Income.
