General Information [Abstract] |
General Information | GENERAL INFORMATION The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all information and disclosures required by generally accepted accounting principles (GAAP) in the United States (U.S.). Therefore, this information should be read in conjunction with Freeport-McMoRan Inc.’s (FCX) consolidated financial statements and notes contained in its annual report on Form 10-K for the year ended December 31, 2016. The information furnished herein reflects all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods reported. With the exception of the accounting for discontinued operations and assets held for sale, all such adjustments are, in the opinion of management, of a normal recurring nature. As a result of FCX’s sale of its interest in TF Holdings Limited (TFHL), FCX has reported TFHL as discontinued operations for all periods presented in the unaudited consolidated financial statements (refer to Note 2). Operating results for the three-month period ended March 31, 2017, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017. Oil and Gas Properties. In first-quarter 2016, FCX Oil & Gas LLC (FM O&G, a wholly owned subsidiary of FCX) determined the carrying values of certain of its unevaluated properties were impaired as of March 31, 2016. As a result, FM O&G transferred $3.1 billion of costs associated with unevaluated properties to the full cost pool, mostly reflecting impairment of the carrying values of unevaluated properties. Combined with the impact of the reduction in twelve-month historical prices and reserve revisions in first-quarter 2016, net capitalized costs exceeded the related ceiling test limitation under full cost accounting rules, which resulted in the recognition of a $3.8 billion impairment charge. Refer to Note 1 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion.
