Income Taxes

Effective Income Tax Rate and Income Tax Provision

On December 22, 2017, the U.S. Tax Cut and Jobs Act of 2017 ("TCJA") was enacted, substantially changing the U.S. tax system and affecting the Company in a number of ways. Notably, the TCJA:


•	establishes a flat corporate income tax rate of 21.0% on U.S. earnings;


•	imposes a one-time tax on unremitted cumulative non-U.S. earnings of foreign subsidiaries (“Transition Tax”);


•	generally allows for the repatriation of future earnings of foreign subsidiaries without incurring additional U.S. taxes by transitioning to a territorial system of taxation;


•	imposes a new minimum tax on certain non-U.S. earnings, irrespective of the territorial system of taxation, global intangible low-taxed income (GILTI);


•	subjects certain payments made by a U.S. company to a related foreign company to certain minimum taxes (Base Erosion Anti-Abuse Tax);


•	eliminates certain prior tax incentives for manufacturing in the United States and creates an incentive for U.S. companies to sell, lease or license goods and services abroad by allowing for a reduction in taxes owed on earnings related to such sales;


•	allows the cost of investments in certain depreciable assets acquired and placed in service after September 27, 2017 to be immediately expensed;


•	reduces deductions with respect to certain compensation paid to specified executive officers; and


•	allows for installment payments to be paid over a period of eight years.

On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared or analyzed in reasonable detail to complete the accounting for certain income tax effects of TCJA. SAB 118 provides that where reasonable estimates can be made, the provisional accounting should be based on such estimates and when no reasonable estimate can be made, the provisional accounting may be based on the tax law in effect before the TCJA. We have applied the guidance in SAB 118 when accounting for the enactment-date effects of TCJA. Accordingly, we remeasured U.S. deferred tax assets and liabilities based on the income tax rates at which the deferred tax assets and liabilities are expected to reverse in the future (generally 21%), in 2017. This remeasurement resulted in $41.1 million of tax expense for the year ended December 31, 2017. At December 31, 2017, we were not able to reasonably estimate the impact of Transition Tax. For a description of the impact of the TCJA for the year ended December 31, 2017, reference is made to Note 16, “Income Taxes,” of the Notes to Consolidated Financial Statements contained in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2017

The one-time Transition Tax is based our total post-1986 earnings and profits ("E&P") which we had deferred from U.S taxes under prior law. During the three months ended March 31, 2018, the Company recognized a provisional tax liability of $290.0 million for the Transition Tax. The actual amount of Transition Tax may differ from the provisional amount due to, among other things, changes in tax calculations associated with the sale of Diversey, which we have not yet finalized, changes in interpretations and assumptions the Company has made, changes in the treatment of Transition Tax by state taxing authorities and additional regulatory guidance that may be issued. Any adjustments made to the provisional amounts under SAB 118 will be recorded as discrete adjustments in the period identified (not to extend beyond the one-year measurement period provided in SAB 118). The accounting is expected to be complete when the 2017 U.S. corporate income tax return is filed in 2018.

For interim tax reporting, we estimate one single effective tax rate for tax jurisdictions not subject to a valuation allowance, which is applied to the year-to-date ordinary income/(loss). Tax effects of significant unusual or infrequently occurring items are excluded from the estimated annual effective tax rate calculation and recognized in the interim period in which they occur.

Our effective income tax rate for the three months ended March 31, 2018 was 283.3%. The difference between the Company’s effective income tax rate and the U.S. statutory rate of 21.0% relates to the provisional amount for Transition Tax associated with the TCJA, non-deductible expenses, state income taxes, and the effect of the GILTI provision enacted as part of the TCJA.

Our effective income tax rate for the three months ended March 31, 2017 was 164.9%. The rate is greater than the statutory rate primarily due to $126.9 million of tax expense related to the sale of Diversey, offset by $9.3 million of excess tax benefits on share-based compensation.

The GILTI provisions, which require us to include in our U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary's tangible assets, are complex and subject to continuing regulatory interpretation by the U.S. Internal Revenue Service ("IRS"). We are required to make an accounting policy election 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 the Company’s measurement of its deferred taxes (the “deferred method”). We have elected to recognize the GILTI as a period expense in the period the tax is incurred. Under this policy, we have not provided deferred taxes related to temporary differences that upon their reversal will affect the amount of income subject to GILTI in the period. This election increases the annual effective tax rate by approximately 3.6%. We will continue to refine our calculation which may result in changes to this amount.
