Membership Interests [Abstract]
MEMBERSHIP INTERESTS	8. MEMBERSHIP INTERESTS Contributions On February 17, 2022, we received cash capital contributions from our members totaling $106 million. During 2021, we received the following cash capital contributions from our members. Receipt Date AmountFebruary 16, 2021 $ 63April 27, 2021 $ 63July 27, 2021 $ 62October 26, 2021 $ 67December 22, 2021 $ 450 Distributions Distributions are limited by the requirement to maintain our regulatory capital structure at or below the debt-to-equity ratio established periodically by the PUCT for ratemaking purposes. The PUCT has the authority to determine what types of debt and equity are included in a utility’s debt-to-equity ratio. For purposes of this ratio, debt is calculated as long-term debt including any finance leases plus unamortized gains on reacquired debt less unamortized issuance expenses, premiums and losses on reacquired debt. Equity is calculated as membership interests determined in accordance with GAAP, excluding accumulated other comprehensive loss and the effects of acquisition accounting from a 2007 transaction. The PUCT order issued in the Sempra Acquisition and our Limited Liability Company Agreement set forth various restrictions on distributions to our members. Among those restrictions is the commitment that we will make no distributions (other than contractual tax payments) to our members that would cause us to exceed the PUCT’s authorized debt-to-equity ratio. Our current authorized regulatory capital structure is 57.5% debt to 42.5% equity. The distribution restrictions also include the ability of a majority of our Disinterested Directors, or either of the two member directors designated by Texas Transmission, to limit distributions to the extent each determines it is necessary to meet expected future requirements of Oncor (including continuing compliance with the PUCT debt-to-equity ratio commitment). At December 31, 2021, our regulatory capitalization was 53.1% debt to 46.9% equity, and as a result we had $1.463 billion available to distribute to our members. On February 18, 2022, our board of directors declared a cash distribution of $106 million, which was paid to our members on February 18, 2022. During 2021, our board of directors declared, and we paid, the following cash distributions to our members: Declaration Date Payment Date AmountFebruary 17, 2021 February 18, 2021 $ 96April 28, 2021 April 29, 2021 $ 96July 28, 2021 July 29, 2021 $ 546October 27, 2021 October 28, 2021 $ 101 Accumulated Other Comprehensive Income (Loss) (AOCI) The following table presents the changes to AOCI for the years ended December 31, 2021, 2020 and 2019 net of tax.
