Note 13. Income Taxes

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act ("Tax Act"). The Tax Act makes broad and complex changes to the U.S. tax code that affected 2017, including, but not limited to, (1) requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over eight years and (2) bonus depreciation that will allow for full expensing of qualified property.

The Tax Act also establishes new tax laws that affected 2018, including, but not limited to (1) the reduction of the U.S. federal corporate tax rate from 35% to 21%; (2) the elimination of the corporate alternative minimum tax ("AMT"); (3) the creation of the base erosion anti-abuse tax ("BEAT"), a new minimum tax; (4) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (5) a new provision designed to tax global intangible low-taxed income ("GILTI"), which allows for the possibility of using foreign tax credits ("FTC") and a deduction of up to 50% to offset the income tax liability (subject to some limitations); (6) a new limitation on deductible interest expense; (7) the repeal of the domestic production activity deduction; (8) limitations on the deductibility of certain executive compensation; (9) limitations on the use of FTCs to reduce the U.S. income tax liability; and (10) limitations on net operating losses ("NOL") generated after December 31, 2017, to 80% of taxable income.

The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company's accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, a company must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, a company should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

The Company has not completed the accounting for the income tax effects of certain elements of the Tax Act. If the Company was able to make reasonable estimates of the effects of elements for which an analysis is not yet complete, the Company recorded provisional adjustments, as described above. If the Company was not yet able to make reasonable estimates of the impact of certain elements, the Company has not recorded any adjustments related to those elements and have continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect before the Tax Act. As the Company completes the accounting of the income tax effects of the Tax Act, the Company anticipates that additional charges or benefits may be recorded at such time as prescribed by ASC 740 and SAB 118, and as further information becomes available regarding the Tax Act, the Company may make further adjustments to the provisions that have been recorded in the financial statements. The Company also continues to examine the impact of this tax reform legislation.

The Tax Act reduces the corporate tax rate to 21%, effective January 1, 2018. While the Company was able to make a reasonable estimate of the impact of the reduction in the corporate rate, that estimate may be affected by other analyses related to the Tax Act, including, but not limited to, a calculation of deemed repatriation of deferred foreign income and the state tax effect of adjustments made to federal temporary differences. In the nine month period ended September 30, 2018, the benefit recognized of $89.6 million in 2017 was increased by $8.2 million to $97.8 million in the three month period ended September 30, 2018. No additional changes were made to the $69.0 million benefit related to the reduction of the ASC 740-30 liability. These both remain estimates as of September 30, 2018.

The Deemed Repatriation Transition Tax ("Transition Tax") is a tax on previously untaxed accumulated and current earnings and profits ("E&P") of certain of the Company's foreign subsidiaries. To determine the amount of the Transition Tax, we must determine, in addition to other factors, the amount of post-1986 E&P of the relevant subsidiaries, the amount of non-U.S. income taxes paid on such earnings, and the impact of the accumulated overall foreign source loss on the Company's ability to utilize foreign tax credits. As of the nine month period ended September 30, 2018, the Company revised its estimate for the Transition Tax obligation to $51.7 million from the $63.3 million expensed in 2017. The Company continues to gather additional information to more precisely compute the amount of the Transition Tax obligation. The Transition Tax obligation remains an estimate as of September 30, 2018.

The Company's accounting for the following elements of the Tax Act is incomplete, and no provisional adjustments, other than the adjustment related to the effects of the transitional tax, were recorded related to ASC 740-30.

Due to complexities, the Company has not yet determined if a change to the policy concerning permanent reinvestment will be made as a result of the Tax Act. No additional adjustments relating to ASC 740-30 have been recorded in accordance with SAB 118.

For 2018, the Tax Act creates a new requirement that certain income (i.e., GILTI) earned by controlled foreign corporations ("CFC") must be included currently in the gross income of the CFCs' U.S. shareholder. GILTI is the excess of the shareholder's "net CFC tested income" over the net deemed tangible income return, which is currently defined as the excess of (1) 10% of the aggregate of the U.S. shareholder's pro rata share of the qualified business asset investment of each CFC with respect to which it is a U.S. shareholder over (2) the amount of certain interest expense taken into account in the determination of net CFC-tested income.

Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the "period cost method") or (2) factoring such amounts into a company's measurement of its deferred taxes (the "deferred method"). The Company has determined that it will follow the period costs method (option 1 above) going forward. The tax provision for the nine month period ended September 30, 2018 reflects this decision. All of the additional calculations and rule changes found in the Tax Act have been considered in the tax provision for the three and nine month periods ended September 30, 2018.

The following table summarizes the Company's provision (benefit) for income taxes and effective income tax provision rate for the three and nine month periods ended September 30, 2018 and 2017.

	For the Three Month Periods Ended September 30,						For the Nine Month Periods Ended September 30,
	2018			2017			2018			2017
Income (loss) before income taxes	$	94.8		$	32.4		$	238.1		$	(166.3	)
Provision (benefit) for income taxes	$	22.6		$	4.4		$	63.2		$	(41.2	)
Effective income tax rate		23.8	%		13.6	%		26.5	%		24.8	%

The increase in the provision for income taxes for the three month period ended September 30, 2018 when compared to the same three month period in 2017 is primarily due to the overall increase in global earnings when compared to the prior year. The effective income tax provision rate was impacted by the increase in global earnings and reduced by the windfall tax benefit to result in an overall increase in the rate for the three month period ended September 30, 2018 when compared to the same three month period of 2017.

The increase in the provision for income taxes and increase in the effective income tax provision rate for the nine month period ended September 30, 2018 when compared to the same nine month period of 2017 is primarily due to the overall increase in global earnings when compared to the prior year.
