Based upon the contractual maturities, principal payments on the above notes are due in the amounts of $1.9 million in 2021, $0.9 million in 2022, $0.1 million in 2023 and $98.9 million in 2025.

Prior to May 2020, the Company had an available $150.0 million unsecured line of credit commitment (Existing Credit Agreement) for general corporate and acquisitions purposes and was previously scheduled to expire in November 2023. Under this agreement, interests are calculated, at the Company's election, based on either (a) an Alternate Base Rate plus the Applicable Rate (ABR Borrowing) or (b) LIBOR plus the Applicable Rate (Eurodollar Borrowing). The Applicable Rate, based on the Company's Leverage Ratio, ranges from 0.375% to 0.50% per annum for ABR Borrowings and 1.375% to 1.75% per annum for Eurodollar Borrowings based on the Company's consolidated Leverage Ratio. Also, a commitment fee accrues ranging from 0.20% to 0.35% per annum on the average daily unused portion of the line of credit commitment.

The Existing Credit Agreement contains customary affirmative and negative covenants, which include consolidated financial covenants (based on terms defined within the agreement) providing that (a) the ratio of EBITDA to fixed charges not be below 1.15 to 1.00 on a trailing four-quarter basis (Fixed Charge Ratio); (b) the ratio of total Indebtedness to EBITDA for the prior four consecutive quarters must not be greater than 3.50 to 1.00 (Leverage Ratio); (c) Capital Expenditures in the aggregate for the Company in any calendar year may not exceed $30.0 million, with certain allowances for carryover of unused amounts; and (d) Restricted Payments should not exceed $40.0 million annually.

In May 2020, the Company entered into an amended agreement with the lenders (First Amendment) which increased the available unsecured line of credit commitment to $200.0 million and extended the maturity of the line of credit to May 2025. The First Amendment, which includes an additional $50.0 million that the Company can request, revised the definition of EBITDA and added customary LIBOR benchmark replacement language to the Existing Credit Agreement.

As of December 31, 2020, line of credit borrowings of $98.9 million were outstanding and the remaining balance of the line of credit available for use was $98.6 million, net of an unused $2.5 million letter of credit. The Company was in compliance with all covenants as of December 31, 2020 and 2019, under the First Amendment and Existing Credit Agreement.

The Company's qualified intermediary in tax-deferred property exchanges pursuant to Section 1031 of the Internal Revenue Code (Section 1031) enters into short-term loan agreements with parties to an exchange in the ordinary course of its business. The outstanding balances pursuant to these loans, as included within other notes payable in the above table, were $0.7 million and $8.0 million as of December 31, 2020 and 2019, respectively, and are secured by cash that is included in cash and cash equivalents on the Company's consolidated balance sheet. Borrowings and repayments on these short-term loans are reflected as financing activities in the consolidated statements of cash flows.
