Goodwill And Intangible Assets Disclosure [Abstract] |
Goodwill | (5) GOODWILL During 2016, we recorded goodwill associated with the acquisition of Memorial Resource Development Corp. (the “MRD Merger”), which represented the cost of the acquired entity over the net amounts assigned to assets acquired and liabilities assumed. Goodwill is assessed for impairment whenever events or circumstances indicate that impairment of the carrying value of goodwill is likely, but no less often than annually. During fourth quarter 2017, we performed our annual qualitative assessment of goodwill to determine whether it was more likely than not that the fair value of our business (our reporting unit) was less than its carrying amount. Based on the results of this assessment, we determined it was not likely that goodwill was impaired. We are not aware of any events or circumstances that occurred during first quarter 2018 that would have more likely than not reduced the fair value of our reporting unit below its carrying value.
