At September 30, 2021 and December 31, 2020, the net difference between the carrying amount of Dominion Energy’s investments and its share of underlying equity in net assets was $231 million and $213 million, respectively. At September 30, 2021, these differences are comprised of $27 million of equity method goodwill that is not being amortized, a $222 million basis difference from Dominion Energy’s investment in Cove Point, which is being amortized over the useful lives of the underlying assets, and a net $(18) million basis difference primarily attributable to an unfunded commitment made to Align RNG. At December 31, 2020, these differences are comprised of $27 million of equity method goodwill that is

not being amortized, a $227 million basis difference from Dominion Energy’s investment in Cove Point, which is being amortized over the useful lives of the underlying assets, and a net $(41) million basis difference primarily attributable to an unfunded commitment made to Align RNG.

In November 2020, in conjunction with the GT&S Transaction, Dominion Energy sold 100% of its general partner interest and 25% of the total limited partner interest in Cove Point. Dominion Energy retained a 50% noncontrolling limited partnership interest in Cove Point which is accounted for as an equity method investment, as discussed in Note 9 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020.

Income before income taxes recorded by Cove Point was $136 million and $132 million for the three months ended September 30, 2021 and 2020, respectively, and $410 million and $396 million for the nine months ended September 30, 2021 and 2020, respectively. For the periods prior to closing of the GT&S Transaction, earnings attributable to Dominion Energy are presented in discontinued operations and subsequent to the closing, earnings attributable to Dominion Energy are presented within earnings from equity method investees in its Consolidated Statements of Income.

Dominion Energy recorded distributions from Cove Point of $85 million and $235 million for the three and nine months ended September 30, 2021, respectively. No contributions were made to Cove Point for the three and nine months ended September 30, 2021.

A description of Dominion Energy’s investment in Atlantic Coast Pipeline, including events that led to the cancellation of the Atlantic Coast Pipeline Project in July 2020, is included in Note 9 to the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

At September 30, 2021 and December 31, 2020, Dominion Energy has recorded a liability of $112 million and $1.1 billion, respectively, in its Consolidated Balance Sheets as a result of its share of equity losses exceeding its investment which reflects Dominion Energy’s obligations on behalf of Atlantic Coast Pipeline related to its credit facility, through February 2021, and AROs.

In February 2021, Atlantic Coast Pipeline repaid the outstanding borrowed amounts and terminated its revolving credit facility. As of December 31, 2020, Atlantic Coast Pipeline had borrowed $1.8 billion against the revolving credit facility. Concurrently, Dominion Energy’s related guarantee agreement to support its portion of Atlantic Coast Pipeline’s borrowings was also terminated. Dominion Energy’s Consolidated Balance Sheets included a liability of $6 million associated with this guarantee agreement at December 31, 2020.

Dominion Energy recorded contributions of $45 million during the three months ended September 30, 2020, and $965 million and $74 million during the nine months ended September 30, 2021 and 2020, respectively, to Atlantic Coast Pipeline. Dominion Energy recorded no contributions during the three months ended September 30, 2021 to Atlantic Coast Pipeline.

Dominion Energy expects to incur additional losses from Atlantic Coast Pipeline as it completes wind-down activities. While Dominion Energy is unable to precisely estimate the amounts to be incurred by Atlantic Coast Pipeline, the portion of such amounts attributable to Dominion Energy is not expected to be material to Dominion Energy’s results of operations, financial position or statement of cash flows.

DETI provided services to Atlantic Coast Pipeline which totaled $7 million and $44 million for the three and nine months ended September 30, 2020, respectively, included in discontinued operations in Dominion Energy’s Consolidated Statements of Income.

The related disposal group is primarily comprised of customer receivables, goodwill, inventories, derivative assets and liabilities and accounts payable. All activity related to Wrangler is recorded in the Corporate and Other segment.

In September 2020, Dominion Energy sold its 50% noncontrolling partnership interest in Fowler Ridge to BP and terminated an affiliate’s long-term power, capacity and renewable energy credit contract with Fowler Ridge for a net payment by Dominion Energy of $150 million. Dominion Energy recognized a loss of $221 million ($165 million after-tax) on the contract termination, included in impairment of assets and other charges in its Consolidated Statements of Income for the three and nine months ended September 30, 2020.

The $150 million payment was allocated between the contract termination and sale based on the relative fair value of each using an income approach. The fair value determinations for the payment allocations are considered Level 3 fair value measurements due to the use of significant judgmental and unobservable inputs, including the amount of future cash flows and discount rate reflecting risks inherent in the future cash flows and market prices.
