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 presented in securities due within one year and amounts which represent the unamortized debt issuance costs and discount or premium. Additionally, the Dominion Energy carrying amount includes portions classified as held for sale and presented in current liabilities held for sale and noncurrent liabilities held for sale.
