INCOME TAXES	INCOME TAXES The provision for taxes is based upon using the Company's projected annual effective tax rate of 22% before non-recurring discrete items for the three month periods ended March 31, 2018 and 2017. The difference between the Company's projected annual effective tax rate of 22% and its reported tax rate of 21% and 19% during the three months ending March 31, 2018 and 2017, respectively, is related to the timing of excess tax benefits associated with stock option exercises. On December 22, 2017, the Tax Cuts and Jobs Act (the "Act") significantly revised U.S. corporate income tax law. The Act includes, among other things, a reduction in the U.S. federal corporate income tax rate from 35% to 21% effective for taxable years beginning after December 31, 2017, and the implementation of a modified territorial tax system that includes a one-time transition tax on deemed repatriated earnings of foreign subsidiaries ("Transition Tax") that is payable over a period of up to eight years. Our accounting for the Act is based upon reasonable estimates, however, the Company estimates may change upon the finalization of the Act's implementation and additional interpretive guidance from regulatory authorities. Among other things, the Company needs to complete its analysis of historical foreign earnings and related taxes paid and its analysis of foreign cash equivalents. In addition, the Company needs to complete its analysis of deemed repatriation of deferred foreign income and related state tax effects.
