Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivatives and Hedge Accounting Activities | NOTE 7. DERIVATIVES AND HEDGE ACCOUNTING ACTIVITIES See Note 2 for the Companies’ accounting policies, objectives and strategies for using derivative instruments. See Notes 2 and 6 for further information about fair value measurements and associated valuation methods for derivatives. Cash collateral is used in the table below to offset derivative assets and liabilities. In February 2022, Dominion Energy entered into contracts representing offsetting positions to certain existing exchange contracts with collateral requirements as well as new over-the-counter transactions that are not subject to collateral requirements. These contracts resulted in positions which limit the risk of increased cash collateral requirements. Certain accounts receivable and accounts payable recognized on the Companies’ Consolidated Balance Sheets, letters of credit and other forms of securities, as well as certain other long-term debt, all of which are not included in the tables below, are subject to offset under master netting or similar arrangements and would reduce the net exposure. See Note 18 for further information regarding other long-term debt, in the form of restructured derivatives, subject to offset under master netting or similar agreements. See Note 24 for further information regarding credit-related contingent features for the Companies derivative instruments. Balance Sheet Presentation The tables below present the Companies’ derivative asset and liability balances by type of financial instrument, if the gross amounts recognized in its Consolidated Balance Sheets were netted with derivative instruments and cash collateral received or paid:
