Earnings Per Share Computations Table Basic EPS is calculated by dividing earnings attributable to common shares (from both continuing and discontinued operations) by the weighted-average number of common shares outstanding for the period. Diluted EPS includes the potential dilution of common stock equivalent shares that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

(1)    Includes 451 and 535 fully vested RSUs held in our Deferred Compensation Plan for the three months ended September 30, 2021 and 2020, respectively, and 453 and 536 of such RSUs for the nine months ended September 30, 2021 and 2020, respectively. These fully vested RSUs are included in weighted-average common shares outstanding for basic EPS because there are no conditions under which the corresponding shares will not be issued.
(2)    In the three months ended September 30, 2021, the total weighted-average number of potentially dilutive stock options and RSUs was 699. However, these securities were not included in the computation of EPS because to do so would have decreased losses per share.
(3)    Due to market fluctuations of both Sempra common stock and the comparative indices used to determine the vesting percentage of our total shareholder return performance-based RSUs, which we discuss in Note 10 of the Notes to Consolidated Financial Statements in the Annual Report, dilutive RSUs may vary widely from period-to-period.

(1)    Amounts include principal balances plus accumulated interest outstanding.
(2)    U.S. dollar-denominated loan at a variable interest rate based on 1-month LIBOR plus 196 bps (2.11% at December 31, 2020). At December 31, 2020, $1 million of accrued interest receivable is included in Due from Unconsolidated Affiliates – Current. In March 2021, IEnova acquired the 50% equity interest in ESJ that it did not already own and ESJ became a wholly owned, consolidated subsidiary, resulting in the elimination of this note receivable.
(3)    Mexican peso-denominated revolving line of credit for up to 14.2 billion Mexican pesos or approximately $689 million U.S. dollar-equivalent at September 30, 2021, at a variable interest rate based on the 91-day Interbank Equilibrium Interest Rate plus 220 bps (7.02% at September 30, 2021), to finance construction of a natural gas marine pipeline. At both September 30, 2021 and December 31, 2020, $2 million of accrued interest receivable is included in Due from Unconsolidated Affiliates – Current. At September 30, 2021, we classified this revolving line of credit as noncurrent because we expect to extend the maturity date on a long-term basis prior to its stated maturity date.
(4)    U.S. dollar-denominated loan at a variable interest rate based on 6-month LIBOR plus 290 bps (3.06% at September 30, 2021).
(5)     U.S. dollar-denominated loans at fixed interest rates.
(6)    SDG&E and SoCalGas are included in the consolidated income tax return of Sempra, and their respective income tax expense is computed as an amount equal to that which would result from each company having always filed a separate return.

The following table summarizes income statement information from unconsolidated affiliates.
