Income Taxes	Note 11. Income Taxes Our effective income tax rate was 23.4 percent for the three months ended September 30, 2017, as compared to 30.8 percent for the three months ended September 30, 2016, and 22.8 percent for the nine months ended September 30, 2017, as compared to 30.7 percent for the nine months ended September 30, 2016. The decrease in our effective tax rate for the three months ended September 30, 2017, as compared to the same period in the prior year, was primarily related to the adoption of ASU 2016-09 related to share-based compensation, which reduced our effective tax rate by approximately 4 percent, and the expected utilization of foreign tax credits, which reduced our effective tax rate by approximately 3 percent. The decrease in our effective tax rate for the nine months ended September 30, 2017, as compared to the same period in the prior year, was primarily related to the adoption of ASU 2016-09 related to share-based compensation, which reduced our effective tax rate by approximately 8 percent, and the expected utilization of foreign tax credits, which reduced our effective tax rate by approximately 1 percent.
