Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill (CenterPoint Energy and CERC) | Goodwill (CenterPoint Energy and CERC) CenterPoint Energy’s goodwill by reportable segment as of both March 31, 2024 and December 31, 2023 is as follows:
|  | December 31, 2023 |  | Held For Sale |  |  |  | March 31, 2024
|  | (in millions)
Electric (1) |  | $ | 936 |  |  | $ | — |  |  |  |  | $ | 936 |
Natural gas (2) |  | 2,920 |  |  | 217 |  |  |  |  | 2,703 |

(1)Amount presented is net of the accumulated goodwill impairment charge of $185 million recorded in 2020. (2)If a disposal group reflects a component of a reporting unit and meets the definition of a business, the goodwill within that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As a result, goodwill attributable to the Louisiana and Mississippi natural gas LDC businesses to be disposed of is classified as held for sale as of March 31, 2024. CenterPoint Energy has not recognized any goodwill impairments within the Natural Gas reportable segment during the three months ended March 31, 2024. For further information, see Note 3. CERC’s goodwill as of both March 31, 2024 and December 31, 2023 is as follows:
|  | December 31, 2023 |  | Held For Sale |  |  |  | March 31, 2024
|  | (in millions)
Goodwill (1) |  | $ | 1,583 |  |  | $ | 122 |  |  |  |  | $ | 1,461 |
(1)In connection with the classification of the Louisiana and Mississippi natural gas LDC businesses as held for sale as of March 31, 2024 described above, goodwill attributable to CERC to be disposed of as part of the transaction is classified as held for sale as of March 31, 2024. CERC has not recognized any goodwill impairments during the three months ended March 31, 2024. For further information, see Note 3. CenterPoint Energy and CERC perform goodwill impairment tests at least annually and evaluate goodwill when events or changes in circumstances indicate that its carrying value may not be recoverable. The impairment evaluation for goodwill is performed by comparing the fair value of each reporting unit with the carrying amount of the reporting unit, including goodwill. The reporting units approximate the reportable segments, with the exception of Energy Systems Group, which was a separate reporting unit but was included in Corporate and Other at CenterPoint Energy. The estimated fair value of the reporting unit is primarily determined based on an income approach or a weighted combination of income and market approaches. If the carrying amount is in excess of the estimated fair value of the reporting unit, then the excess amount is recorded as an impairment charge, not to exceed the carrying amount of goodwill.
