Income Tax Disclosure [Abstract] |
INCOME TAXES | 13. INCOME TAXES The effective tax rate for the three and nine months ended September 30, 2019 was 19.8% and 21.0%, respectively. The effective tax rate for the three and nine months ended September 30, 2018 was 17.2% and 19.3%, 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 effective tax rates for the current year periods are higher than the prior year periods primarily due to the full application of the international provisions of U.S. tax reform, as well as the discrete effect of accruing taxes attributable to the undistributed earnings of operations in China that are expected to be remitted in the future. The total amount of unrecognized tax benefits was reduced from $1.3 million to $0.1 million during the nine months ended September 30, 2019 due to the resolution of transfer pricing matters associated with the Canadian taxing authority.
