Goodwill and Intangible Assets

NOTE 11. GOODWILL AND INTANGIBLE ASSETS

Goodwill

In September 2020, Dominion Energy updated its operating segments following the July 2020 agreement to sell its gas transmission and storage operations to BHE. See Note 3 for information on the goodwill recast to held for sale associated with the GT&S Transaction and Q-Pipe Transaction. In addition, goodwill associated with Dominion Energy’s nonregulated retail energy marketing operations was reassigned to the Corporate and Other segment using a relative fair value allocation approach with the historical information recast herein. The changes in Dominion Energy’s carrying amount and segment allocation of goodwill are presented below:
