Income Tax Disclosure [Abstract] |
INCOME TAXES | 12. INCOME TAXES The effective tax rate for the three months ended March 31, 2019 and 2018 was 21.7% and 19.6%, respectively. WESCO’s effective tax rate is typically impacted by the tax effect of intercompany financing, foreign tax rate differences, nondeductible expenses and state income taxes. The higher effective tax rate for the three months ended March 31, 2019 was primarily due to the full application of the international provisions of U.S. tax reform. There have been no material adjustments to liabilities for uncertain tax positions since the last annual disclosure for the year ended December 31, 2018.
