Tax Cuts and Jobs Act

During the fourth quarter of 2017, the TCJ Act was enacted in the United States. Among its many provisions, the TCJ Act imposed a mandatory one-time transition tax on undistributed international earnings and reduced the U.S. corporate income tax rate from 35% to 21%, effective January 1, 2018. As a result of the enactment of the TCJ Act, we recognized a provisional net tax expense of $2.5 billion in the fourth quarter of 2017. See Note 5 to our consolidated financial statements in our 2017 Form 10-K for further information on this provisional net tax expense.

During the first quarter of 2018, we recorded an additional provisional transition tax expense of $1 million, reflecting the impact of actions taken by states within the United States that adopted the TCJ Act. Additionally, during the second quarter of 2018, the Internal Revenue Service (IRS) issued new transition tax guidance. As a result of this guidance, we expect to record additional provisional transition tax expense in the second quarter of 2018 of approximately $700-$800 million.

The TCJ Act also created a new requirement that certain income earned by foreign subsidiaries, known as global intangible low-tax income (GILTI), must be included in the gross income of their U.S. shareholder. The FASB allows an accounting policy election of either recognizing deferred taxes for temporary differences expected to reverse as GILTI in future years or recognizing such taxes as a current-period expense when incurred. During the first quarter of 2018, we elected to treat the tax effect of GILTI as a current-period expense when incurred.

The components of the provisional net tax expense recorded in 2017 and the first quarter of 2018 were based on currently available information and additional information needs to be prepared, obtained and/or analyzed to determine the final amounts. The provisional tax expense for the mandatory repatriation of undistributed international earnings will require further analysis of certain foreign exchange gains or losses, substantiation of foreign tax credits, as well as estimated cash and cash equivalents as of November 30, 2018, the tax year-end of our foreign subsidiaries. The provisional tax benefit for the remeasurement of deferred taxes will require additional information necessary for the preparation of our U.S. federal tax return, and further analysis and interpretation of certain provisions of the TCJ Act impacting deferred taxes, for example 100% expensing of qualified assets, could impact our deferred tax balance as of December 30, 2017.

Tax effects for these items will be recorded in subsequent quarters, as discrete adjustments to our income tax provision, once complete. We elected to adopt the SEC issued guidance that allows for a measurement period, not to exceed one year after the enactment date of the TCJ Act, to finalize the recording of the related tax impacts. We currently anticipate finalizing and recording any resulting adjustments by the end of 2018.

The recorded impact of the TCJ Act is provisional and the final amount may differ, possibly materially, due to, among other things, changes in estimates, interpretations and assumptions we have made, changes in IRS interpretations, the issuance of new guidance, legislative actions, changes in accounting standards or related interpretations in response to the TCJ Act and future actions by states within the United States that have not currently adopted the TCJ Act.

Risk Factors” and Note 5 to our consolidated financial statements in our 2017 Form 10-K and “Our Critical Accounting Policies,” “Our Business Risks” and “Our Liquidity and Capital Resources” in Management’s Discussion and Analysis of Financial Condition and Results of Operations in this Form 10-Q.
