Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our effective tax rate was 27 percent and 26 percent for the three-month and nine-month periods ended September 30, 2018, respectively. Our tax rate was higher than our 2018 statutory tax rate of 21 percent due primarily to an increase from U.S. and foreign taxes on foreign earnings of four percent, and an increase from state and local taxes, net of U.S. Federal tax benefit, of two percent and three percent for the three-month and nine-month periods ended September 30, 2018, respectively. The effective tax rate in the three-month period was also higher by one percent due to non-deductible compensation resulting from recently issued IRS guidance related to the application of the 2017 Act. These increases were partially offset by an income tax benefit on stock-based compensation of one percent and two percent for the three-month and nine-month periods ended September 30, 2018, respectively. Our effective tax rate of 38 percent for the three-month period ending September 30, 2017 was higher than our 2017 statutory tax rate of 35 percent due primarily to an increase from state and local taxes, net of U.S. Federal tax benefit, of two percent, an increase due to a change in the mix of earnings from lower to higher tax jurisdictions of two percent, partially offset by an income tax benefit on stock-based compensation of one percent. Our effective tax rate of 34 percent for the nine-month period ending September 30, 2017 was lower than our 2017 statutory tax rate due primarily to an income tax benefit on stock-based compensation of three percent, partially offset by an increase from state and local taxes, net of U.S. Federal tax benefit, of two percent.

Our effective tax rate was 27 percent and 26 percent for the three-month and nine-month periods ended September 30, 2018, respectively. Our tax rate was higher than our 2018 statutory tax rate of 21 percent due primarily to an increase from U.S. and foreign taxes on foreign earnings of four percent, and an increase from state and local taxes, net of U.S. Federal tax benefit, of two percent and three percent for the three-month and nine-month periods ended September 30, 2018, respectively. The effective tax rate in the three-month period was also higher by one percent due to non-deductible compensation resulting from recently issued IRS guidance related to the application of the 2017 Act.

Our effective tax rate of 38 percent for the three-month period ending September 30, 2017 was higher than our 2017 statutory tax rate of 35 percent due primarily to an increase from state and local taxes, net of U.S. Federal tax benefit, of two percent, an increase due to a change in the mix of earnings from lower to higher tax jurisdictions of two percent, partially offset by an income tax benefit on stock-based compensation of one percent. Our effective tax rate of 34 percent for the nine-month period ending September 30, 2017 was lower than our 2017 statutory tax rate due primarily to an income tax benefit on stock-based compensation of three percent, partially offset by an increase from state and local taxes, net of U.S. Federal tax benefit, of two percent.
