Equity	4. EQUITY For all periods presented, DESC's authorized shares of common stock, no par value, were 50 million, of which 40.3 million were issued and outstanding, and DESC's authorized shares of preferred stock, no par value, were 20 million, of which 1,000 shares were issued and outstanding. All outstanding shares of common and preferred stock are held by SCANA. In September 2020, Dominion Energy issued $322 million of shares of Dominion Energy common stock in accordance with the settlement agreement associated with the Santee Cooper Ratepayer Case, as discussed in Note 12. In connection with this transaction, DESC recorded an equity contribution from Dominion Energy. During the three and nine months ended September 30, 2019, DESC received equity contributions of $50 million and $825 million, respectively, from its parent that were funded by Dominion Energy. DESC used these funds to redeem long-term debt and to repay intercompany credit agreement borrowings from Dominion Energy. See Note 6 to the Consolidated Financial Statements in DESC’s Annual Report on Form 10-K for the year ended December 31, 2019. At September 30, 2020, DESC’s retained earnings exceed the balance established by the Federal Power Act as a reserve on earnings attributable to hydroelectric generation plants. As a result, DESC is permitted to pay dividends without additional regulatory approval provided that such amounts would not bring the retained earnings balance below the threshold. There have been no other significant changes to dividend restrictions affecting DESC described in Note 5 to the Consolidated Financial Statements in DESC’s Annual Report on Form 10-K for the year ended December 31, 2019.
