On December 22, 2017, the U.S. government enacted comprehensive tax legislation (the “Tax Act”), which significantly revises the ongoing U.S. corporate income tax law by lowering the U.S. federal corporate income tax rate from 35% to 21%, implementing a territorial tax system, imposing one-time tax on foreign unremitted earnings and setting limitations on deductibility of certain costs (e.g., interest expense), among other things. Due to the complexities involved in accounting for the recently enacted Tax Act, the U.S. Securities and Exchange Commission’s Staff Accounting Bulletin (“SAB”) 118 requires that the company include in its financial statements the reasonable estimate of the impact of the Tax Act on earnings to the extent such reasonable estimate has been determined. Accordingly, the company recorded the following reasonable estimates of the tax impact in its earnings for the year ended December 31, 2017.
(a) | For the year ended December 31, 2017, the company accrued a reasonable estimate of $196,010 of tax expense for the Tax Act’s one-time transition tax on the foreign subsidiaries’ accumulated, unremitted earnings going back to 1986.
(b) | For the year ended December 31, 2017, the company accrued $71,261 in provisional tax benefit related to the net change in deferred tax liabilities stemming from the Tax Act’s reduction of the U.S. federal tax rate from 35% to 21%, and disallowance of certain incentive based compensation tax deductibility under Internal Revenue Code Section 162(m).
The Tax Act also includes a provision to tax global intangible low-taxed income (“GILTI”) of foreign subsidiaries and a base erosion anti-abuse tax (“BEAT”) measure that taxes certain payments between a U.S. corporation and its subsidiaries. The company will be subject to the GILTI and BEAT provisions effective beginning January 1, 2018 and is in the process of analyzing their effects, including how to account for the GILTI provision from an accounting policy standpoint.
