FCX’s consolidated effective income tax rate was 32 percent for first-quarter 2021 and 10 percent for first-quarter 2020. Because FCX's U.S. jurisdiction generated pre-tax losses in the first three months of 2020 that did not result in a realized tax benefit, applicable accounting rules required FCX to adjust its estimated annual effective tax rate to exclude the impact of U.S. pre-tax losses. Variations in the relative proportions of jurisdictional income result in fluctuations to FCX’s consolidated effective income tax rate. In connection with the negative impacts of the COVID-19 pandemic on the global economy, governments throughout the world are announcing measures that are intended to provide tax and other financial relief. Such measures include the American Rescue Plan Act of 2021 (ARPA), enacted on March 11, 2021, and the Coronavirus Aid, Relief, and Economic Security Act (CARES Act), enacted on March 27, 2020. None of these measures resulted in material impacts to FCX’s provision for income taxes for the three months ended March 31, 2021 and 2020. However, certain provisions of the CARES Act provided FCX with the opportunity to accelerate collections of tax refunds, primarily those associated with the U.S. alternative minimum tax. FCX collected U.S. alternative minimum tax credit refunds of $221 million in July 2020 and $24 million in October 2020. FCX collected the remaining U.S. alternative minimum tax credit refund of $23 million in March 2021. FCX continues to evaluate income tax accounting considerations of COVID-19 measures as they develop, including any impact on its measurement of existing deferred tax assets and deferred tax liabilities. FCX will recognize any impact from COVID-19 related changes to tax laws in the period in which the new legislation is enacted.
