Derivative Instruments | Note 6.Derivative Instruments Derivative financial instruments are used to manage exposure to commodity price risk resulting from SCE’s electricity and natural gas procurement activities. The risks of fluctuating commodity prices are managed in part by entering into forward commodity transactions, including options, swaps and futures. To mitigate credit risk from counterparties in the event of nonperformance, master netting agreements are used whenever possible, and counterparties may be required to pledge collateral depending on the creditworthiness of each counterparty and the risk associated with the transaction. Certain power and gas contracts contain a provision that requires SCE to maintain an investment grade rating from the major credit rating agencies, referred to as a credit-risk-related contingent feature. If SCE's credit rating were to fall below investment grade, SCE may be required to post additional collateral to cover derivative liabilities and the related outstanding payables. The fair value of these derivative contracts and any related collateral were immaterial as of June 30, 2024 and December 31, 2023. SCE presents its derivative assets and liabilities, recorded at fair value, on a net basis on its consolidated balance sheets when subject to master netting agreements or similar agreements. Derivative positions are also offset against margin and cash collateral deposits. See Note 4 for a discussion of fair value of derivative instruments. The following table summarizes the gross and net fair values of SCE's commodity derivative instruments: ​

At June 30, 2024, SCE posted and accrued $180 million of cash collateral, of which $100 million was offset against derivative liabilities and $80 million was reflected in "Other current assets" on SCE's consolidated balance sheets. At December 31, 2023, SCE posted and accrued $121 million of cash collateral, of which $74 million was offset against derivative liabilities and $47 million was reflected in "Other current assets" on the consolidated balance sheets. Financial Statement Impact of Derivative Instruments SCE recognizes realized gains and losses on derivative instruments as purchased power expense and expects that such gains or losses will be part of the purchased power costs recovered from customers. As a result, realized gains and losses do not affect earnings, but may temporarily affect cash flows. Due to the expected future recovery from customers, unrealized gains and losses are recorded as regulatory assets and liabilities and therefore, also do not affect earnings. The remaining effects of derivative activities and related regulatory offsets are reported in cash flows from operating activities in SCE's consolidated statements of cash flows. The following table summarizes the (losses)/gains of SCE's economic hedging activity: ​
