​ Net discount, premium and issuance costs associated with issuing these notes are amortized to expense over the respective terms using the interest method. On March 8, 2023, we issued $700.0 million of senior notes. We issued a $400.0 million series of notes that bear interest at 5.375% and will mature in 2033 and a $300.0 million series of notes that bear interest at 5.5% and will mature in 2053. Interest on the notes is payable semi-annually on March 15 and September 15 each year, beginning on September 15, 2023. The proceeds from these notes were used to repay at maturity our 3.125% notes payable due in 2023 and to redeem our floating rate notes payable due in 2055. We incurred a one-time cost to extinguish this debt before the scheduled maturity date, which was recorded in operating expenses on the consolidated statements of operations.
