Schedule of Annual Maturities of Long-Term Debt

The following schedule of annual maturities of the principal amount of total debt assumes we use available capacity under our revolving credit agreement to refinance unsecured floating rate term loan payments and unsecured notes due in 2019 and 2020. Based on this refinancing assumption, all of the obligations due prior to 2023 are reflected as maturities for 2023, the year the revolving credit agreement expires (in thousands).

The revolving credit agreement expires in 2023. Excluding our ability to repay funds with the revolving credit agreement, contractual debt maturities are $420 million for 2019, $725 million in 2020 and $350 million in 2021.
