Tax Cuts and Jobs Act, Other Tax Effect, Description |  |  |  |  |  |  |  | In 2017, the United States enacted comprehensive tax reform legislation known as the Tax Cuts and Jobs Act (the "2017 Tax Act") that, among other things, reduces the U.S. federal corporate income tax rate from 35% to 21% and implements a territorial tax system, but imposes an alternative "base erosion and anti-abuse tax" ("BEAT"), and an incremental tax on global intangible low taxed foreign income ("GILTI") effective January 1, 2018. In addition, the law imposed a one-time mandatory repatriation tax on accumulated post-1986 foreign earnings on domestic corporations effective for the 2017 tax year. |  |  |
