(2) The effective interest rate is calculated based on LIBOR, plus a margin ranging from 1.35% to 2.20% , depending on our consolidated leverage ratio. The weighted-average interest rate is the all-in interest rate, including the effects of interest swap agreements relating to approximately $150.0 million in borrowings under this term loan. This term loan 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. (3) The effective interest rate is calculated based on LIBOR, plus a margin ranging from 1.65% to 2.55% , depending on our consolidated leverage ratio. The weighted-average interest rate is the all-in interest rate and is fixed through interest swap agreements. This term loan 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. (4) Amount as of March 31, 2018 includes a $32.9 million floating-rate mortgage note that was subject to an interest rate spread of 1.60% over one-month LIBOR, which we have effectively fixed using an interest rate swap at 3.05% for the term of the borrowing. (5) The effective interest rate is calculated based on LIBOR plus a margin. As of both March 31, 2018 and December 31, 2017, our floating rate mortgage notes were subject to a weighted-average interest rate spread of 2.31% . (6) The weighted-average remaining term of our borrowings was approximately 2.6 years as of March 31, 2018 . As of March 31, 2018 , the principal payments due on our debt during each of the next five years and thereafter were as follows: (in thousands) Line of Credit (1) Term Loans (2) Mortgage Notes Total Remainder of 2018 $ — $ — $ 1,957 $ 1,957 2019 186,000 275,000 3,344 464,344 2020 — — 229,088 229,088 2021 — — 12,372 12,372 2022 — 200,000 3,246 203,246 Thereafter — — 151,482 151,482 Total principal payments $ 186,000 $ 475,000 $ 401,489 $ 1,062,489 (1) The term of the line of credit may be extended pursuant to a one -year extension option, subject to certain conditions. (2) The term of the $275.0 million term loan may be extended pursuant to a one -year extension option, subject to certain conditions. 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 covenants, including leverage ratio, fixed charge coverage ratio, and tangible net worth thresholds. We were in compliance with all debt covenants as of March 31, 2018 . 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 on-going exposure to interest rate movements. The change in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) (“AOCI”) on the condensed consolidated balance sheets and is subsequently reclassified into earnings as interest expense for the period that the hedged forecasted transaction affects earnings, which is when the interest expense is recognized on the related debt. During the next 12 months, we estimate that approximately $1.6 million will be reclassified as a decrease to interest expense related to active effective hedges of existing floating-rate debt, and we estimate that approximately $1.7 million will be reclassified as an increase to interest expense related to effective interest rate swaps where the hedging instrument has been terminated.
