Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill | Goodwill The Companies test goodwill for impairment at least annually or whenever there is a triggering event. There is an option to first make a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount before applying a quantitative goodwill impairment test. The quantitative goodwill impairment test compares the estimated fair value of a reporting unit with its carrying value, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying value, goodwill of the reporting unit is considered not impaired. If the carrying value exceeds the estimated fair value of the reporting unit, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Con Edison has recorded goodwill related to the O&R merger and the acquisition of a portion of Honeoye. Further, included within Con Edison's assets held for sale as of December 31, 2022 is goodwill related to the acquisitions of a residential solar company and a battery storage company by the Clean Energy Businesses. On March 1, 2023, Con Edison completed the sale of all of the stock of the Clean Energy Businesses. See Note W and Note X. In 2023 and 2022, Con Edison completed quantitative and qualitative impairment tests, respectively, for its goodwill of $406 million related to the O&R merger and determined that it was not impaired. For the impairment test, $245 million and $161 million of goodwill were allocated to CECONY and O&R, respectively. In 2021, Con Edison determined, based on a discounted cash flow analysis, that $7 million of goodwill was impaired related to Honeoye, $5 million of which was attributed to Con Edison Transmission and $2 million of which was attributed to CECONY. The remaining goodwill attributable to Honeoye was not material at December 31, 2023 or 2022. No other impairments or triggering events were identified for Con Edison's goodwill for the years ending December 31, 2023, 2022 or 2021. Estimates of future cash flows, projected growth rates, and discount rates inherent in the cash flow estimates for Con Edison subsidiaries other than the Utilities may vary significantly from actual results, which could result in a future impairment of goodwill.
