Income Tax Disclosure [Abstract] |
INCOME TAXES | INCOME TAXES FirstEnergy’s and FES’ interim effective tax rates reflect the estimated annual effective tax rates for 2017 and 2016. These tax rates are affected by estimated annual permanent items, such as AFUDC equity and other flow-through items, as well as discrete items that may occur in any given period, but are not consistent from period to period. FirstEnergy’s effective tax rate for the three months ended March 31, 2017 and 2016 was 38.1% and 39.4%, respectively. The decrease in the effective tax rate is primarily due to tax benefits recognized in the first quarter of 2017. FES’ effective tax rate for the three months ended March 31, 2017 and 2016 was 33.9% on pre-tax losses and 38.5% on pre-tax income, respectively. The change in the effective tax rate is primarily due to valuation allowances on state tax benefits resulting from charges associated with long-term coal transportation contract disputes, as discussed in Note 10, Commitments, Guarantees, and Contingencies. As of March 31, 2017, it is reasonably possible that approximately $51 million of unrecognized tax benefits may be resolved within the next twelve months as a result of the statute of limitations expiring and expected resolution with respect to certain claims, of which approximately $26 million would affect FirstEnergy's effective tax rate. In February 2017, the IRS completed its examination of FirstEnergy's 2015 federal income tax return and issued a Full Acceptance Letter with no changes or adjustments to FirstEnergy's taxable income or effective tax rate.
