New Accounting Standards | NEW ACCOUNTING STANDARDFinancial Instruments. In June 2016, the Financial Accounting Standards Board issued an Accounting Standards Update (ASU) that requires entities to estimate all expected credit losses for most financial assets held at the reporting date based on an expected loss model, which requires consideration of historical experience, current conditions, and reasonable and supportable forecasts. FCX adopted this ASU effective January 1, 2020, and the adoption of this ASU did not have a material impact on its consolidated financial statements.
