NEW ACCOUNTING STANDARDS

In April 2015, the Financial Accounting Standards Board issued an Accounting Standards Update (ASU) to simplify the presentation of debt issuance costs. This ASU requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. For public entities, this ASU is effective for annual periods beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. FCX adopted this ASU in first-quarter 2015 and retrospectively adjusted its previously issued financial statements. Upon adoption, FCX adjusted its December 31, 2014, balance sheet by decreasing other assets and long-term debt by $121 million for debt issuance costs related to corresponding debt balances. FCX elected to continue presenting debt issuance costs for its revolving credit facility as a deferred charge (asset) because of the volatility of its borrowings and repayments under the facility.
