(1)CenterPoint Energy’s lower effective tax rate on income from continuing operations for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 was primarily driven by the recognition of additional tax benefit for increased NOL carryback claims under the CARES Act and the effects of the lower book earnings on other rate drivers in the three months ended September 30, 2020.

(2)CenterPoint Energy’s higher effective tax rate on the loss from continuing operations for the nine months ended September 30, 2020 compared to the income from continuing operations for the nine months ended September 30, 2019 was primarily due to lower earnings from the impairment of CenterPoint Energy’s investment in Enable. Other effective tax rate drivers include the tax benefit for the NOL carryback claims under the CARES Act, which was partially offset by the non-deductible goodwill impairment at the Indiana Electric Integrated reporting unit.

(3)CenterPoint Energy’s lower effective tax rate on the loss from discontinued operations for the three months ended September 30, 2020 compared to the income from discontinued operations for the three months ended September 30, 2019 was primarily due to lower book earnings in the three months ended September 30, 2020.

(4)CenterPoint Energy’s lower effective tax rate on the loss from discontinued operations for the nine months ended September 30, 2020 compared to the income from discontinued operations for the nine months ended September 30, 2019 was primarily due to the tax impacts from the sale of the Infrastructure Services Disposal Group on April 9, 2020 and the sale of the Energy Services Disposal Group on June 1, 2020, the effect of which was compounded by lower book earnings in the nine months ended September 30, 2020. See Note 3 for further information.

(5)Houston Electric’s lower effective tax rate for the three and nine months ended September 30, 2020 compared to the same periods for 2019 was primarily due to an increase in the amount of amortization of the net regulatory EDIT liability.

(6)CERC’s higher effective tax rate on the loss from continuing operations for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 was driven by an increase in the amount of amortization of the net regulatory EDIT liability and a larger return-to-accrual tax benefit recognized in the three months ended September 30, 2020. These were partially offset by the absence of state deferred tax benefits as a result of certain state tax law changes and the release of a valuation allowance on certain state NOLs that were reported in the three months ended September 30, 2019.
