INCOME TAXES	6 Months Ended

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Note 5. Income Taxes The effective tax rate increased for the quarter primarily driven by $291 million of tax costs associated with the internal restructuring of the transportation systems business in advance of its anticipated spin-off and decreased tax benefits from employee share-based payments, partially offset by tax benefits from US Tax Reform. The effective tax rate increased for the six months primarily driven by $291 million of tax costs associated with the internal restructuring of the transportation systems business in advance of its anticipated spin-off and decreased tax benefits from employee share-based payments, partially offset by tax benefits from US Tax Reform and decreased tax expense for reserves. The effective tax rate for the quarter and six months ended June 30, 2018 was higher than the U.S. federal statutory rate of 21% primarily from tax costs associated with the internal restructuring of the transportation systems business in advance of its anticipated spin-off, state income taxes and U.S tax reform’s expansion of the anti-deferral rules that impose U.S. taxes on foreign earnings. On December 22, 2017, the U.S. government enacted tax legislation that included changes to the taxation of foreign earnings by implementing a dividend exemption system, expansion of the current anti-deferral rules, a minimum tax on low-taxed foreign earnings and new measures to deter base erosion. The tax legislation also included a permanent reduction in the corporate tax rate to 21%, repeal of the corporate alternative minimum tax, expensing of capital investment, and limitation of the deduction for interest expense. Furthermore, as part of the transition to the new tax system, a one-time transition tax was imposed on a U.S. shareholder’s historical undistributed earnings of foreign affiliates. As described in Note 5 Income Taxes in our 2017 Annual Report on Form 10-K, we were able to reasonably estimate certain effects of the tax legislation and, therefore, recorded provisional amounts, including the deemed repatriation transition tax. The Company has not finalized the accounting for the tax effects of the tax legislation and for the six months ended June 30, 2018, we have not made any material measurement period adjustments related to the provisional amounts. However, we continue to gather additional information and expect to complete our accounting within the prescribed measurement period.
