Income Taxes [Abstract]
Income Taxes	Note 9 – Income Taxes On December 22, 2017, the U.S. Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law. The Tax Act significantly changed the U.S. corporate income tax law by lowering the statutory corporate tax rate from 35% to 21%, imposing a one-time mandatory repatriation tax on earnings of foreign subsidiaries, and changing how foreign earnings are subject to U.S. tax. Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Act, we made reasonable estimates of the effects and recorded provisional amounts in our financial statements as of December 31, 2017, pursuant to the guidance of the U.S. Securities and Exchange Commission Staff Accounting Bulletin No. 118. We recorded income tax expense in 2017 for the impact of the Tax Act of approximately $13.0 million. This 2017 net amount is primarily comprised of $8.3 million from re-measurement of federal net deferred tax assets resulting from the reduction in the U.S. statutory corporate tax rate and a provisional amount of $4.7 million from the one-time mandatory repatriation tax on deferred earnings of our foreign subsidiaries. As we complete our analysis of the Tax Act, collect and prepare necessary data, and interpret any additional guidance issued by the U.S. Treasury Department and the IRS, we may make adjustments to the provisional amount. Those adjustments may materially impact our provision for income taxes in the period in which the adjustments are made. The accounting for the tax effects of the Tax Act will be completed in 2018. The interim provision for income taxes is different from the amount determined by applying the U.S. federal statutory rate to consolidated income before taxes. The differences are attributable to foreign tax rate differential, unrecognized tax benefits, and foreign tax credit. Our effective tax rate was 27.6% and 25.5% for the six months ended June 30, 2018 and 2017, respectively. The change between 2018 and 2017 is primarily related to the reduction of U.S. statutory corporate tax rate as the result of the Tax Act, foreign tax credit, partially offset by a change in the foreign tax rate differential and non-taxable insurance proceeds received in 2017.

Note 9 – Income Taxes

On December 22, 2017, the U.S. Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law. The Tax Act significantly changed the U.S. corporate income tax law by lowering the statutory corporate tax rate from 35% to 21%, imposing a one-time mandatory repatriation tax on earnings of foreign subsidiaries, and changing how foreign earnings are subject to U.S. tax. Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Act, we made reasonable estimates of the effects and recorded provisional amounts in our financial statements as of December 31, 2017, pursuant to the guidance of the U.S. Securities and Exchange Commission Staff Accounting Bulletin No. 118. We recorded income tax expense in 2017 for the impact of the Tax Act of approximately $13.0 million. This 2017 net amount is primarily comprised of $8.3 million from re-measurement of federal net deferred tax assets resulting from the reduction in the U.S. statutory corporate tax rate and a provisional amount of $4.7 million from the one-time mandatory repatriation tax on deferred earnings of our foreign subsidiaries. As we complete our analysis of the Tax Act, collect and prepare necessary data, and interpret any additional guidance issued by the U.S. Treasury Department and the IRS, we may make adjustments to the provisional amount. Those adjustments may materially impact our provision for income taxes in the period in which the adjustments are made. The accounting for the tax effects of the Tax Act will be completed in 2018.

The interim provision for income taxes is different from the amount determined by applying the U.S. federal statutory rate to consolidated income before taxes. The differences are attributable to foreign tax rate differential, unrecognized tax benefits, and foreign tax credit. Our effective tax rate was 27.6% and 25.5% for the six months ended June 30, 2018 and 2017, respectively. The change between 2018 and 2017 is primarily related to the reduction of U.S. statutory corporate tax rate as the result of the Tax Act, foreign tax credit, partially offset by a change in the foreign tax rate differential and non-taxable insurance proceeds received in 2017.
