Income Tax Disclosure [Abstract] |
INCOME TAXES | 9. INCOME TAXES The effective tax rate for the three and six months ended June 30, 2017 was 25.3% and 25.1%, respectively. The effective tax rate for the three and six months ended June 30, 2016 was 27.3% and 29.2%, respectively. WESCO’s effective tax rate is lower than the federal statutory rate of 35% due to benefits resulting from the tax effect of intercompany financing and lower tax rates on foreign earnings, which are partially offset by nondeductible expenses and state taxes. The current year's effective tax rate is lower than the prior year primarily due to favorable discrete items, including a benefit from the exercise and vesting of stock-based awards, as well as the mix of income earned in jurisdictions with lower tax rates. The total amount of unrecognized tax benefits was reduced by $1.5 million during the six months ended June 30, 2017 to $4.7 million due to the expiration of statutes of limitation and the settlement of state audits. At June 30, 2017, the amount of unrecognized tax benefits that could affect the effective tax rate if recognized in the consolidated financial statements was $6.0 million. Within the next twelve months, it is reasonably possible that the amount of unrecognized tax benefits will decrease by approximately $0.3 million due to the expiration of statutes of limitation and the settlement of state audits. Of this amount, $0.1 million could impact the effective tax rate.
