_________________________
(1)Interest rates are the stated rates of interest on the debt instrument (not the effective interest rate) as of March 31, 2026, and therefore exclude the effects of related interest rate swaps and accretion and amortization of debt issuance costs related to refinancing transactions and additional borrowings. We present stated rates of interest because they reflect the rate at which cash will be paid for future debt service, except for the Sierre loan, for which interest is assessed in arrears.
(2)Amounts include unamortized debt issuance costs, fair value adjustments, and debt discounts.
(3)The Series 2025A Bonds and Series 2025B Bonds, as defined below, accrue interest at a fixed annual rate of 5% and 4.625%, respectively, ending with a mandatory tender for purchase on June 1, 2032. The Series 2025A and Series 2025B Bonds will mature on June 1, 2055.
(4)The Series 2026A Bonds, as defined below, accrue interest at a fixed annual rate of 4.3%, ending with a mandatory tender for purchase on March 1, 2033. The Series 2026A Bonds will mature on March 1, 2056.
