Subsequent Events [Abstract] |
Subsequent Events | SUBSEQUENT EVENTS As reported in Note 13 of FCX's annual report on Form 10-K for the year ended December 31, 2014, PT-FI entered into a Memorandum of Understanding (MOU) with the Indonesian government in July 2014. Under the MOU, PT-FI provided a $115 million assurance bond to support its commitment for smelter development, agreed to increased royalty rates and agreed to pay export duties (which were set at 7.5 percent, declining to 5.0 percent when smelter development progress exceeds 7.5 percent and are eliminated when development progress exceeds 30 percent). The MOU also anticipated an amendment of the COW within six months to address other matters; however, no terms of the COW other than those relating to the smelter bond, increased royalties and export duties were changed. In January 2015, the MOU was extended to July 25, 2015, and it expired on that date. The increased royalty rates, export duties and smelter assurance bond remain in effect. PT-FI is also required to apply for renewal of export permits at six-month intervals. On July 29, 2015, PT-FI's export permit was renewed through January 28, 2016. In connection with the renewal, export duties were reduced to 5.0 percent, as a result of smelter development progress. FCX evaluated events after June 30, 2015, and through the date the consolidated financial statements were issued, and determined any events or transactions occurring during this period that would require recognition or disclosure are appropriately addressed in these consolidated financial statements.
