Related-Party Transactions [Abstract]
RELATED-PARTY TRANSACTIONS	10. RELATED-PARTY TRANSACTIONS The following represent our significant related-party transactions and related matters. We are not a member of another entity’s consolidated tax group, but our owners’ federal income tax returns include their portion of our results. Under the terms of a tax sharing agreement among us, Oncor Holdings, Texas Transmission and STH, we are generally obligated to make payments to our owners, pro rata in accordance with their respective membership interests, in an aggregate amount that is substantially equal to the amount of federal income taxes that we would have been required to pay if we were filing our own corporate income tax return. STH will file a combined Texas margin tax return which includes our results and our share of Texas margin tax payments, which are accounted for as income taxes and calculated as if we were filing our own return. See discussion in Note 1 under “Provision in Lieu of Income Taxes.” Under the “in lieu of” tax concept, all in lieu of tax assets and tax liabilities represent amounts that will eventually be settled with our members. In the event such amounts are not paid under the tax sharing agreement, it is probable that these regulatory amounts will continue to be included in Oncor’s rate setting processes. Amounts payable to (receivable from) members related to income taxes under the agreement and reported on our balance sheet consisted of the following: At December 31, 2021 At December 31, 2020 STH Texas Transmission Total STH Texas Transmission Total Federal income taxes payable (receivable) $ (5) $ (1) $ (6) $ (6) $ (1) $ (7)Texas margin tax payable 24 - 24 23 - 23Net payable (receivable) $ 19 $ (1) $ 18 $ 17 $ (1) $ 16 Cash payments made to our members related to income taxes consisted of the following: Year Ended December 31, 2021 2020 2019 STH Texas Transm.
