​ Note 1. Basis of Presentation The accompanying condensed financial statements of Edison International Parent should be read in conjunction with the consolidated financial statements and notes thereto of Edison International and subsidiaries ("Registrant") included in this Form 10-K. Edison International Parent's significant accounting policies are consistent with those of the Registrant, SCE and other wholly owned and controlled subsidiaries. Dividends Received Edison International Parent received cash dividends from SCE of $1.3 billion, $975 million and $1.3 billion in 2022, 2021 and 2020, respectively. Dividend Restrictions CPUC holding company rules require that SCE's dividend policy be established by SCE's Board of Directors on the same basis as if SCE were a stand-alone utility company, and that the capital requirements of SCE, as deemed to be necessary to meet SCE's electricity service obligations, shall receive first priority from the Boards of Directors of both Edison International and SCE. In addition, the CPUC regulates SCE's capital structure which limits the dividends it may pay to its shareholders. The common equity component of SCE's CPUC authorized capital structure is 52% on a weighted average basis over the January 1, 2023 to December 31, 2025 compliance period. This is unchanged from the January 1, 2020 to December 31, 2022 compliance period. The CPUC authorized capital structure differs from the capital structure calculated based on GAAP due to certain exclusions allowed by CPUC, including the impact of SCE's contributions to the Wildfire Insurance Fund under AB 1054. For further information, see "Business—SCE—Overview of Ratemaking Process" and "Business—Southern California Wildfires." In May 2020, the CPUC issued a decision on SCE's application to the CPUC for waiver of compliance with its equity ratio requirement, that allows SCE to exclude from its equity ratio calculations (i) net charges accrued in connection with the 2017/2018 Wildfire/Mudslide Events and (ii) debt issued for the purpose of paying claims related to the 2017/2018 Wildfire/Mudslide Events up to an amount equal to the net charges accrued in connection with the 2017/2018 Wildfire/Mudslide Events. With these exclusions, SCE was in compliance with its authorized capital structure for the compliance period from January 1, 2020 to December 31, 2022. The temporary exclusion lapsed on May 7, 2022. In April 2022, SCE filed another application requesting continued waiver of compliance with its equity ratio requirement. Under the CPUC's rules, SCE will not be deemed to be in violation of the equity ratio requirement while the waiver application is pending resolution. While the exclusion is in place, SCE is required to notify the CPUC if an adverse financial event reduces SCE's spot equity ratio by more than one percent from the level most recently filed with the CPUC in the proceeding. The last spot equity ratio SCE filed with the CPUC in the proceeding did not exclude the then $1.8 billion net charge and was 45.2% as of December 31, 2018 (at the time the common equity component of SCE's CPUC authorized capital structure was required to remain at or above 48% on a weighted average basis over the applicable 37-month period). SCE's spot equity ratio on December 31, 2018 would have been 48.7% had the $1.8 billion net charge at December 31, 2018 been excluded, therefore SCE will notify the CPUC if its spot ratio drops below 47.7% in any quarter. For further information, see "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies—Contingencies—Southern California Wildfires and Mudslides." Note 2. Debt and Equity Financing Long-Term Debt At December 31, 2022, Edison International Parent had, $400 million of 2.95% senior notes due in 2023, $500 million of 3.55% senior notes due in 2024, $400 million of 4.95% senior notes and $400 million of 4.70% senior notes due in 2025, $600 million of 5.75% senior notes due in 2027, $550 million of 4.125% senior notes due in 2028 and $550 million 6.95% senior notes due in 2029. Credit Agreements and Short-Term Debt The following table summarizes the status of the credit facility at December 31, 2022:
​ | ​ | ​ | ​
(in millions) |  |  | ​

Outstanding borrowings | ​ |  | 90
Amount available | ​ | $ | 1,410
In May 2022, Edison International Parent amended its revolving credit facility to extend the termination date to May 2026. The aggregate maximum principal amount under the Edison International Parent revolving credit facility may be increased up to $2.0 billion, provided that additional lender commitments are obtained. As of December 31, 2022, Edison International Parent has outstanding term loans of $600 million due in April 2023 and $400 million due in November 2023, each bearing interest at either an adjusted term SOFR plus 0.70% and 0.95%, respectively, or a base rate with no applicable margin. Edison International used the proceeds for general corporate purposes. The debt covenant in Edison International Parent's credit facility requires a consolidated debt to total capitalization ratio of less than or equal to 0.70 to 1. At December 31, 2022, Edison International's consolidated debt to total capitalization ratio was 0.64 to 1. Equity In the third quarter of 2022, Edison International filed a prospectus supplement and executed several distribution agreements with certain sales agents to establish an "at-the-market"("ATM") program, under which it may sell shares of its common stock having an aggregate sales price of up to $500 million. As of December 31, 2022, no sales had occurred and Edison International has no obligation to sell the remaining available shares. Edison International continued to settle its ongoing common stock requirements of various internal programs through issuance of new common stock. During the twelve months ended December 31, 2022, 1,253,049 shares of common stock were issued as stock compensation awards for net cash receipts of $57 million, 273,642 shares of new common stock were issued in lieu of distributing $18 million to shareholders opting to receive dividend payments in the form of additional common stock, 157,000 shares of common stock were purchased by employees through the 401(k) defined contribution savings plan for net cash receipts of $10 million as dividend payments, 109,750 shares of common stock were issued related to optional cash investments of $7 million and 36,912 shares of common stock were issued to employees through the ESPP for net cash receipts of $2 million. During the twelve months ended December 31, 2021, 629,092 shares of common stock were issued as stock compensation awards for net cash receipts of $25 million, 522,400 shares of common stock were purchased by employees through the 401(k) defined contribution savings plan for net cash receipts of $30 million, 293,031 shares of new common stock were issued in lieu of distributing $17 million to shareholders opting to receive dividend payments in the form of additional common stock and 26,475 shares of common stock related to optional cash investments of $2 million. Starting July 2021, the 401(k) defined contribution savings plan no longer offers Edison International's stock as an investment option to employees. Subsequent to the change, stock issued through the 401(k) defined contribution savings plan were dividend payments made in the form of additional common stock. Preferred Stock Issuance In 2021, Edison International issued 1,250,000 shares of 5.375% Fixed-Rate Reset Cumulative Perpetual Preferred Stock, Series A, and 750,000 shares of its 5.00% Fixed-Rate Reset Cumulative Perpetual Preferred Stock, Series B, each with a liquidation value of $1,000 per share. The dividends are payable on a semi-annual basis, commencing September 15, 2021 and March 15, 2022, respectively. The dividend rate will be reset every five years beginning on March 15, 2026 and March 15, 2027, respectively, to equal the then-current five-year U.S. Treasury rate plus a spread of 4.698% and 3.901%, respectively. The net proceeds of $2.0 billion were used to repay commercial paper borrowings and for general corporate purposes, including making a total of $900 million equity contribution to SCE. Note 3. Related-Party Transactions Edison International's Parent expense from services provided by SCE was $2 million in 2022, $2 million in 2021 and $2 million in 2020. Edison International Parent's interest expense from loans due to affiliates was $3 million in 2022, $5 million in 2021 and $4 million in 2020. Edison International Parent had current related-party receivables of $389 million and $361 million and current related-party payables of $166 million and $211 million at December 31, 2022 and 2021, respectively. Edison International Parent had long-term related-party receivables of $8 million and $52 million at December 31, 2022 and 2021, respectively, and long-term related-party payables of $130 million and $227 million at December 31, 2022 and 2021, respectively.
