9. Income Taxes

In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (“SAB 118”). This update provides guidance on income tax accounting implications under Public Law 115-97, informally known as the Tax Cuts and Jobs Act (the "Tax Act"), which was enacted on December 22, 2017. The Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering the statutory corporate tax rate from 35 percent to 21 percent, eliminating certain deductions, imposing a mandatory one-time tax on accumulated earnings of foreign subsidiaries, introducing new tax regimes, and changing how foreign earnings are subject to U.S. tax. SAB 118 addressed the application of GAAP to situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act.

As of the fourth quarter of 2017, the Company had not completed the determination of the accounting implications of the Tax Act on the Company’s tax accruals. However, we reasonably estimated the effects of the Tax Act and recognized a provisional net tax expense of $99 million associated with the Tax Act in the fourth quarter of 2017. During the second quarter of 2018, the Company reduced its provisional calculation by $1 million, which represented a revised estimate of foreign tax credits. Our accounting for the Tax Act is still incomplete as we have not finalized the deemed repatriation of deferred foreign income and prior-year deferred tax activity. We are continuing to gather additional information to complete our accounting for these items and expect to complete our accounting within the one-year time period provided by SAB 118.

The Company continues to evaluate the provisions of the Tax Act, including the global intangible low-taxed income (“GILTI”), the foreign derived intangible income (“FDII”) provisions, and the base erosion and anti-abuse tax (“BEAT”). The Company has made an accounting policy election to treat GILTI taxes as a current period expense.

The ultimate effect of the Tax Act may differ from these provisional amounts, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued, as well as any related actions the Company may take.
