The income tax expense for the third quarter and first nine months of 2017 was calculated using the forecasted multi-jurisdictional annual effective tax rates to determine a blended annual effective tax rate. The effective tax rate differs from the U.S. federal statutory rate of 35% primarily due to the projected mix of earnings in international jurisdictions with relatively lower tax rates and tax benefits related to foreign tax credits, which are partially offset by losses in jurisdictions with no tax benefit due to valuation allowances.

Income tax expense increased for the third quarter of 2017 compared to the third quarter of 2016 primarily due to the significant increase in pre-tax earnings, primarily in non-U.S. jurisdictions. The expense was partially offset by favorable U.S. tax deductions, tax credits and favorable discrete tax amounts.

Income tax expense for the nine months ended September 30, 2017 is lower than the nine months ended September 30, 2016 primarily due to the net reversal of accruals for prior year uncertain tax positions recorded discretely and favorable U.S. tax deductions and tax credits.
