INCOME TAXES

For interim tax reporting, we estimate one single effective tax rate for tax jurisdictions not subject to a valuation allowance, which is applied to the year-to-date ordinary income/(loss). Tax effects of significant unusual or infrequently occurring items are excluded from the estimated annual effective tax rate calculation and recognized in the interim period in which they occur.

For the second quarter of 2016 and 2017, our effective tax rates were 31.4% and 9.3%, respectively. During the second quarter of 2017, we recognized a $421 million benefit for foreign tax credits expected to be realized in the foreseeable future. The tax benefit relates to investments in certain non-U.S. subsidiaries previously determined to be indefinitely reinvested in operations outside the United States. Our change in assertion for these investments is related to planned distributions in anticipation of potential U.S. corporate tax reform.
