(1)In the third quarter of 2024, we issued $700 million principal amount of Senior Unsecured Notes due in July 2034 (“2034 Notes”), which bear interest at a rate of 6.375%. The notes were issued for gross proceeds of $695 million, resulting in a yield to maturity of 6.476%. We used a portion of the proceeds from this issuance to redeem the outstanding principal amount of the 2025 notes. There was no premium paid upon redemption.
(2)Prior to this date, we may redeem, at our option, some or all of the 2026 Notes for the outstanding principal amount plus the applicable “make-whole” premium as defined in the indenture governing the 2026 Notes plus accrued and unpaid interest through the redemption date. In addition, prior to this date, we may redeem up to 40% of the Senior Unsecured Notes using the proceeds of certain equity offerings at a price equal to par plus the coupon percentage of the principal amount thereof, plus accrued but unpaid interest, if any, to, but excluding, the applicable redemption date. On, or subsequent to, this date we may redeem the 2026 Notes in whole or in part at redemption prices defined in the indenture governing the 2026 Notes, plus accrued and unpaid interest though the redemption date.
(3)Prior to this date, we may redeem, at our option, some or all of the 2027 Notes for the outstanding principal amount plus the applicable “make-whole” premium as defined in the indenture governing the 2027 Notes plus accrued and unpaid interest through the redemption date. In addition, prior to this date, we may redeem up to 40% of the Senior Unsecured Notes using the proceeds of certain equity offerings at a price equal to par plus the coupon percentage of the principal amount thereof, plus accrued but unpaid interest, if any, to, but excluding, the applicable redemption date. On, or subsequent to, this date we may redeem the 2027 Notes in whole or in part at a price equal to 100% of the principal amount, plus accrued and unpaid interest though the redemption date.
(4)In January 2024 in a follow-on offering we issued $200 million principal amount of 2027 Notes for net proceeds of $204 million, equivalent to a yield to maturity of 7.08% for the new issuance.
(5)We issued the $375 million aggregate principal amount of the 2030 Notes for total proceeds of $371 million ($367 million net of issuance costs) at an effective interest rate of 3.87%. We may redeem the 2030 Notes in whole or in part at redemption prices defined in the indenture governing the 2030 Notes plus accrued and unpaid interest though the redemption date.
