Fair Value Measurements

Dec. 31, 2023

NOTE 6. FAIR VALUE MEASUREMENTS

The Companies’ fair value measurements are made in accordance with the policies discussed in Note 2. See Note 7 for additional information about the Companies’ derivative and hedge accounting activities.

The Companies enter into certain physical and financial forwards, futures and options, which are considered Level 3 as they have one or more inputs that are not observable and are significant to the valuation. The discounted cash flow method is used to value Level 3 physical and financial forwards and futures contracts. An option model is used to value Level 3 physical options. The discounted cash flow model for forwards and futures calculates mark-to-market valuations based on forward market prices, original transaction prices, volumes, risk-free rate of return and credit spreads. The inputs into the option models are the forward market prices, implied price volatilities, risk-free rate of return, the option expiration dates, the option strike prices, the original sales prices and volumes. For Level 3 fair value measurements, certain forward market prices and implied price volatilities are considered unobservable.

The following table presents the Companies’ quantitative information about Level 3 fair value measurements at December 31, 2023. The range and weighted average are presented in dollars for market price inputs and percentages for price volatility.

Represents market prices beyond defined terms for Levels 1 and 2.

(4)

Represents volatilities unrepresented in published markets.

Sensitivity of the fair value measurements to changes in the significant unobservable inputs is as follows:


Significant Unobservable Inputs	Position	Change to Input	Impact on Fair Value Measurement
Market price	Buy	Increase (decrease)	Gain (loss)
Market price	Sell	Increase (decrease)	Loss (gain)
Price volatility	Buy	Increase (decrease)	Gain (loss)
Price volatility	Sell	Increase (decrease)	Loss (gain)

Nonrecurring Fair Value Measurements

See Note 3 for information on the nonrecurring fair value measurement associated with Dominion Energy’s acquisition of Birdseye. See Note 9 for information regarding nonrecurring fair value measurements associated with Dominion Energy’s noncontrolling interest in businesses and assets contributed to Wrangler and Dominion Energy’s noncontrolling ownership interest in Dominion Privatization. See Note 10 for information regarding impairment charges recorded by Dominion Energy associated with a corporate office building, nonregulated solar facilities and non-wholly-owned nonregulated solar facilities in partnerships.

In 2023, Dominion Energy recorded a charge of $15 million ($11 million after-tax) presented within discontinued operations in its Consolidated Statements of Income (reflected in the Corporate and Other segment) to adjust certain nonregulated solar assets down to their estimated fair value, using a market approach, of $22 million. The valuation is considered a Level 2 fair value measurement given that it is based on bids received. As discussed in Note 3, these assets were sold in August 2023.

In 2021, Dominion Energy recorded a charge of $20 million ($15 million after-tax) in impairment of assets and other charges in its Consolidated Statements of Income (reflected in the Corporate and Other segment) to write off substantially all of the long-lived assets of its nonregulated retail software development operations to their estimated fair value, using a market approach, of less than $1 million. The valuation is considered a Level 2 fair value measurement given that it is based on bids received.

In 2021, Dominion Energy recorded a charge of $16 million ($12 million after-tax) in impairment of assets and other charges in its Consolidated Statements of Income to adjust a corporate office building down to its estimated fair value, using both an income and market approach, of $26 million. The valuation is considered a Level 3 measurement due to the use of significant judgmental and unobservable inputs, including projected timing and amount of future cash flows and discount rates inherent in the future cash flows and market prices. The corporate office building is reflected in the Corporate and Other segment and presented as held for sale in Dominion Energy’s Consolidated Balance Sheets at both December 31, 2023 and 2022.

Recurring Fair Value Measurements

Fair value measurements are separately disclosed by level within the fair value hierarchy with a separate reconciliation of fair value measurements categorized as Level 3. Fair value disclosures for assets held in the Companies’ pension and other postretirement benefit plans are presented in Note 22.

The following table presents the Companies’ assets and liabilities that are measured at fair value on a recurring basis for each hierarchy level, including both current and noncurrent portions:

Fair Value of Financial Instruments

Substantially all of the Companies’ financial instruments are recorded at fair value, with the exception of the instruments described below, which are reported at historical cost. Estimated fair values have been determined using available market information and valuation methodologies considered appropriate by management. The carrying amount of cash, restricted cash and equivalents, customer and other receivables, affiliated receivables, short-term debt, affiliated current borrowings, payables to affiliates and accounts payable are representative of fair value because of the short-term nature of these instruments. For the Companies’ financial instruments that are not recorded at fair value, the carrying amounts and estimated fair values are as follows:


	Dominion Energy				Virginia Power
	Carrying Amount		Estimated Fair Value(1)		Carrying Amount		Estimated Fair Value(1)
(millions)
December 31, 2023
Long-term debt(2)	$	42,526	$	40,539	$	17,392	$	16,418
Supplemental credit facility borrowings		450		450
Junior subordinated notes(2)		1,388		1,374
December 31, 2022
Long-term debt(2)	$	39,680	$	36,426	$	15,616	$	14,067
Supplemental credit facility borrowings		450		450
Junior subordinated notes(2)		1,387		1,340

Fair value is estimated using market prices, where available, and interest rates currently available for issuance of debt with similar terms and remaining maturities. All fair value measurements are classified as Level 2. The carrying amount of debt issuances with short-term maturities and variable rates refinanced at current market rates is a reasonable estimate of their fair value.

(2)

Carrying amount includes current portions included in securities due within one year and amounts which represent the unamortized debt issuance costs and discount or premium. There were no fair value hedges associated with fixed-rate debt at December 31, 2023 and December 31, 2022. Additionally, Dominion Energy carrying amounts include portions classified as current liabilities held for sale at both December 31, 2023 and 2022.
