New Accounting Pronouncements and Changes in Accounting Principles [Text Block] | NEW ACCOUNTING STANDARDS Revenue Recognition. In May 2014, the Financial Accounting Standards Board (FASB) issued a new Accounting Standards Update (ASU) related to revenue recognition. FCX adopted this standard effective January 1, 2018, under the modified retrospective approach applied to contracts that remain in force at the adoption date. The adoption of this standard did not result in any financial statement impacts or changes to FCX’s revenue recognition policies or processes as revenue is primarily derived from arrangements in which the transfer of control coincides with the fulfillment of performance obligations (refer to Note 1 of FCX’s annual report on Form 10-K for disclosure of FCX’s revenue recognition policy). In connection with the adoption of the standard and consistent with FCX’s policy prior to adoption of the standard, FCX has elected to account for shipping and handling activities performed after control of goods has been transferred to a customer as a fulfillment cost recorded in production and delivery costs on the consolidated statements of income. FCX recognizes revenue for all of its products upon transfer of control in an amount that reflects the consideration it expects to receive in exchange for those products. Transfer of control is in accordance with the terms of customer contracts, which is generally upon shipment or delivery of the product. While payment terms vary by contract, terms generally include payment to be made within 30 days, but not longer than 60 days. Certain of FCX’s concentrate and cathode sales contracts also provide for provisional pricing, which is accounted for as an embedded derivative (refer to Note 6 for further discussion). For provisionally priced sales, 90 percent to 100 percent of the provisional payment is made upon shipment or within 20 days, and final balances are settled in a contractually specified future month (generally one to four months from the shipment date) based on quoted monthly average spot copper prices on the LME or COMEX and the London gold price. FCX’s product revenues are also recorded net of treatment charges, royalties and export duties. Refer to Note 9 for a summary of revenue by product type. Financial Instruments. In January 2016, FASB issued an ASU that amends the guidance on the classification and measurement of financial instruments. This ASU makes limited changes to prior guidance and amends certain disclosure requirements. FCX adopted this ASU effective January 1, 2018, and adoption did not have a material impact on its financial statements. Statement of Cash Flows: Restricted Cash. In November 2016, FASB issued an ASU that changes the classification and presentation of restricted cash and restricted cash equivalents on the statement of cash flows. The ASU requires that a statement of cash flows include the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. FCX adopted this ASU effective January 1, 2018, and adjusted its consolidated statement of cash flows for the three months ended March 31, 2017, to include restricted cash and restricted cash equivalents with cash and cash equivalents. The impact of adopting this ASU for the three months ended March 31, 2017, follows (in millions):
|  | Previously Reported |  | Impact of Adoption |  | Current Presentation
Other, net included in cash flow from investing activities |  | $ | (21 | ) |  | $ | 4 |  |  | $ | (17 | )
Cash flow from investing activities |  | (365 | ) |  | 4 |  |  | (361 | )
Net decrease in cash, cash equivalents, restricted cash and restricted cash equivalents |  | (252 | ) |  | 4 |  |  | (248 | )
Cash, cash equivalents, restricted cash and restricted cash equivalents at beginning of year |  | 4,245 |  |  | 158 |  |  | 4,403 |
Cash, cash equivalents, restricted cash and restricted cash equivalents at end of period |  | 4,001 |  |  | 162 |  |  | 4,163 |
Net Periodic Pension and Postretirement Benefit Cost. In March 2017, FASB issued an ASU that changes how entities with defined benefit pension or other postretirement benefit plans present net periodic benefit cost in the income statement. This ASU requires the service cost component of net periodic benefit cost to be presented in the same income statement line item or items as other compensation costs for those employees who are receiving the benefit. In addition, only the service cost component is eligible for capitalization when applicable (i.e., as a cost of inventory or an internally constructed asset). The other components of net periodic benefit cost are required to be presented separately from the service cost component and outside of operating income. These other components of net periodic benefit cost are not eligible for capitalization, and FCX elected to include these other components in other income, net. FCX adopted this ASU effective January 1, 2018, and adjusted its presentation in the consolidated statement of income for the three months ended March 31, 2017, to conform with the new guidance. The impact of adopting this ASU for the three months ended March 31, 2017, follows (in millions):
|  | Previously Reported |  | Impact of Adoption |  | Current Presentation
Production and delivery |  | $ | 2,200 |  |  | $ | (12 | ) |  | $ | 2,188 |
Total cost of sales |  | 2,589 |  |  | (12 | ) |  | 2,577 |
Selling, general and administrative expenses |  | 153 |  |  | (2 | ) |  | 151 |
Mining exploration and research expenses |  | 15 |  |  | (1 | ) |  | 14 |
Environmental obligations and shutdown costs |  | 27 |  |  | (2 | ) |  | 25 |
Total costs and expenses |  | 2,761 |  |  | (17 | ) |  | 2,744 |
Operating income |  | 580 |  |  | 17 |  |  | 597 |
Other income, net |  | 25 |  |  | (17 | ) |  | 8 |
