INCOME TAXES

Variations in the relative proportions of jurisdictional income result in fluctuations to FCX’s consolidated effective income tax rate. FCX’s consolidated effective income tax rate was 57 percent for first-quarter 2019 and 38 percent for first-quarter 2018. Geographic sources of FCX’s benefit from (provision for) income taxes follow (in millions):

FCX's first-quarter 2019 consolidated effective income tax rate is a function of the combined effective tax rates for the jurisdictions in which FCX operates, excluding the U.S. jurisdiction. Because FCX's U.S. jurisdiction generated net losses in first-quarter 2019 that will not result in a realized tax benefit, applicable accounting rules require FCX to adjust its estimated annual effective tax rate to exclude the impact of U.S. net losses.
