As of March 31, 2020 , the unused and available portions under the line of credit were approximately $450.0 million and $256.0 million , respectively. The line of credit is available for general business purposes including, but not limited to, refinancing of existing indebtedness and financing the acquisition of permitted investments, including commercial properties. (2) The effective interest rate is calculated based on LIBOR, plus a margin ranging from 1.25% to 2.05% , depending on our consolidated leverage ratio. Total commitments for this term loan are $325.0 million . There are no amounts unused or available under this term loan as of March 31, 2020 . The weighted-average interest rate is the all-in interest rate, including the effects of interest rate swap agreements relating to approximately $300.0 million in borrowings under this term loan. (3) The effective interest rate is calculated based on LIBOR, plus a margin ranging from 1.25% to 2.05% , depending on our consolidated leverage ratio. Total commitments for this term loan are $200.0 million . There are no amounts unused or available under this term loan as of March 31, 2020 . The weighted-average interest rate is the all-in interest rate and is fixed through interest swap agreements. (4) The amount outstanding as of March 31, 2020 includes a $50.7 million floating-rate mortgage note that is subject to an interest rate spread of 1.65% over one-month LIBOR, which we have effectively fixed using an interest rate swap at 2.85% until the designated cash flow hedge expires in July 2021. This mortgage note matures in August 2023. (5) The effective interest rate is calculated based on LIBOR plus a margin. As of March 31, 2020 and December 31, 2019 , our floating-rate mortgage note was subject to a weighted-average interest rate spread of 2.25% and 2.25% , respectively. (6) The weighted-average remaining term of our borrowings was approximately 3.3 years as of March 31, 2020 , excluding the impact of certain extension options. As of March 31, 2020 , the principal payments due on our outstanding debt during each of the next five years and thereafter were as follows: (in thousands) Line of Credit Term Loans Mortgage Notes Total Remainder of 2020 $ — $ — $ 2,294 $ 2,294 2021 (1) — — 138,917 138,917 2022 (2) — 200,000 2,780 202,780 2023 (3) — — 48,799 48,799 2024 — 325,000 2,172 327,172 Thereafter — — 141,433 141,433 Total principal payments $ — $ 525,000 $ 336,395 $ 861,395 (1) Includes a $127.0 million floating-rate mortgage note with a maturity date of January 2021. The mortgage note may still be extended an additional one year, subject to certain conditions.

(3) The term of the line of credit may be extended pursuant to two six -month extension options, subject to certain conditions. In July 2017, the Financial Conduct Authority (“FCA”) that regulates LIBOR announced it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. As a result, the Federal Reserve Board and the Federal Reserve Bank of New York organized the Alternative Reference Rates Committee ("ARRC"), which identified the Secured Overnight Financing Rate ("SOFR") as its preferred alternative rate for LIBOR in derivatives and other financial contracts. We are not able to predict when LIBOR will cease to be available or when there will be sufficient liquidity in the SOFR markets. Any changes adopted by the FCA or other governing bodies in the method used for determining LIBOR may result in a sudden or prolonged increase or decrease in reported LIBOR. If that were to occur, our interest payments could change. In addition, uncertainty about the extent and manner of future changes may result in interest rates and/or payments that are higher or lower than if LIBOR were to remain available in its current form. As of March 31, 2020 , our line of credit, term loans and a $50.7 million mortgage note are our only indebtedness with initial maturity dates beyond 2021 that have exposure to LIBOR. The agreements governing the line of credit, term loans and mortgage note provide procedures for determining a replacement or alternative base rate in the event that LIBOR is discontinued. However, there can be no assurances as to whether such replacement or alternative base rate will be more or less favorable than LIBOR. We intend to monitor the developments with respect to the potential phasing out of LIBOR after 2021 and work with our lenders to seek to ensure any transition away from LIBOR will have minimal impact on our financial condition, but can provide no assurances regarding the impact of the discontinuation of LIBOR. Debt Covenants Our line of credit, term loans and mortgage note agreements contain various property-level covenants, including customary affirmative and negative covenants. In addition, the line of credit and term loan agreements contain certain corporate-level financial co venants, including leverage ratio, fixed charge coverage ratio, and tangible net worth thresholds. We were in compliance with our debt covenants as of March 31, 2020 . Derivative Instruments To manage interest rate risk for certain of our variable-rate debt, we use interest rate derivative instruments as part of our risk management strategy. These derivatives are designed to mitigate the risk of future interest rate increases by either providing a fixed interest rate or capping the variable interest rate for a limited, pre-determined period of time. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for us making fixed-rate payments over the life of the interest rate swap agreements without exchange of the underlying notional amount. Interest rate caps involve the receipt of variable amounts from a counterparty at the end of each period in which the interest rate exceeds the agreed fixed price. Interest rate caps are not designated as hedges. Certain of our variable-rate borrowings are not hedged, and therefore, to an extent, we have ongoing exposure to interest rate movements. During the next 12 months, we estimate that approximately $9.1 million will be reclassified as an increase to interest expense related to active effective hedges of existing floating-rate debt, and we estimate that approximately $0.1 million will be reclassified as an increase to interest expense related to terminated hedges where the likelihood of the originally hedged interest payments remains probable.
