Contractual Obligation, Fiscal Year Maturity | Contractual Obligations. We have certain contractual obligations requiring payments at specified periods. The obligations include long-term debt, lease obligations, energy commodity contracts and obligations for various services including pipeline capacity and outsourcing of IT services. The total contractual obligations in existence at December 31, 2020 and their maturities were:

(1) Long-term debt balance excludes unamortized issuance costs and discounts of $86.9 million. (2) Finance lease payments shown above are inclusive of interest totaling $69.7 million. (3) Operating lease payments shown above are inclusive of interest totaling $7.8 million. Operating lease balances do not include obligations for possible fleet vehicle lease renewals beyond the initial lease term. While we have the ability to renew these leases beyond the initial term, we are not reasonably certain (as that term is defined in ASC 842) to do so as they are renewed month-to-month after the first year. If we were to continue the fleet vehicle leases outstanding at December 31, 2020, payments would be $30.0 million in 2021, $27.7 million in 2022, $24.9 million in 2023, $22.0 million in 2024, $19.0 million in 2025 and $21.5 million thereafter. (4)In February 2021, the demand rate increased for our pipeline service obligations, resulting in a total increase of $638.6 million in addition to our future pipeline service obligations shown above. (5)On February 9, 2021, a rail transportation contract for the transportation of coal was fully executed between NIPSCO and a counterparty, replacing the prior agreement. The minimum coal tonnage shipment commitment for 2021 was eliminated under the new agreement, reducing our contractual obligation for 2021 by $12.1 million. (6)Other liabilities shown above are inclusive of the Rosewater Developer payment due in 2023.
