DEBT | 4. DEBT The Company’s consolidated indebtedness is currently comprised of borrowings under its line of credit, term loans and mortgage notes. Borrowings under the non-recourse mortgage notes are secured by mortgages or deeds of trust and related assignments and security interests in collateralized and certain cross-collateralized properties, which are generally owned by single purpose entities. A summary of the Company’s debt is as follows: Weighted-Average Balance as of ($ in thousands) March 31, 2018 December 31, 2017 Maturity Date March 31, 2018 December 31, 2017 Line of credit (1) 2.86% 2.81% January 2020 $ 298,000 $ 275,000 Term loan (2) 2.50% 2.65% January 2021 350,000 350,000 Term loan (3) 3.63% 3.46% May 2022 150,000 150,000 Fixed-rate mortgage notes (4) 3.36% 3.36% July 2020 - December 2025 722,880 722,880 Total principal amount / weighted-average (5) 3.09% 3.10% $ 1,520,880 $ 1,497,880 Less unamortized debt issuance costs $ (8,155 ) $ (8,735 ) Total debt, net $ 1,512,725 $ 1,489,145 Gross book value of properties encumbered by debt $ 1,154,608 $ 1,153,150 (1) The effective interest rate is calculated based on either: (i) the London Interbank Offered Rate (“LIBOR”) multiplied by a statutory reserve rate plus a margin ranging from 1.40% to 2.30% ; or (ii) an alternative base rate plus a margin ranging from 0.40% to 1.30% , each depending on the Company’s consolidated leverage ratio. The weighted-average effective interest rate is the all-in interest rate, including the effects of interest rate swap agreements relating to $150.0 million in borrowings under this line of credit. As of March 31, 2018 , the unused and available portions under the line of credit were both $202.0 million . The line of credit is available for general corporate purposes, including but not limited to the acquisition and operation of permitted investments. (2) The effective interest rate is calculated based on either: (i) LIBOR multiplied by a statutory reserve rate, plus a margin ranging from 1.35% to 2.20% ; or (ii) an alternative base rate plus a margin ranging from 0.35% to 1.20% , each depending on the Company’s consolidated leverage ratio. The weighted-average effective interest rate is the all-in interest rate, including the effects of interest rate swap agreements. This term loan is available for general corporate purposes, including but not limited to the acquisition and operation of permitted investments. (3) The effective interest rate is calculated based on either: (i) LIBOR multiplied by a statutory reserve rate, plus a margin ranging from 1.60% to 2.50% ; or (ii) an alternative base rate plus a margin ranging from 0.60% to 1.50% , each depending on the Company’s consolidated leverage ratio. The weighted-average effective interest rate is the all-in interest rate. This term loan is available for general corporate purposes, including but not limited to the acquisition and operation of permitted investments. (4) Interest rates range from 2.94% to 3.65% , which includes the effects of an interest rate swap agreement relating to a variable-rate mortgage note with an outstanding amount of $97.0 million as of both March 31, 2018 and December 31, 2017 . The assets and credit of each of the Company’s consolidated properties pledged as collateral for the Company’s mortgage notes are not available to satisfy the Company’s other debt and obligations, unless the Company first satisfies the mortgage notes payable on the respective underlying properties. (5) The weighted-average remaining term of the Company’s consolidated debt was approximately 4.3 years as of March 31, 2018 , excluding any extension options on the line of credit. As of March 31, 2018 , the principal payments due on the Company’s consolidated debt during each of the next five years and thereafter were as follows: (in thousands) Line of Credit (1) Term Loans Mortgage Notes Total Remainder of 2018 $ — $ — $ 1,354 $ 1,354 2019 — — 2,191 2,191 2020 298,000 — 15,259 313,259 2021 — 350,000 6,047 356,047 2022 — 150,000 83,579 233,579 Thereafter — — 614,450 614,450 Total principal payments $ 298,000 $ 500,000 $ 722,880 $ 1,520,880 (1) The term of the line of credit may be extended pursuant to a one -year extension option, subject to certain conditions. Debt Covenants The Company’s 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. The Company was in compliance with all debt covenants as of March 31, 2018 . Derivative Instruments To manage interest rate risk for certain of its variable-rate debt, the Company uses interest rate swaps as part of its risk management strategy. These derivatives are designed to mitigate the risk of future interest rate increases by providing a fixed 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 the Company making fixed-rate payments over the life of the interest rate swap agreements without exchange of the underlying notional amount. As of March 31, 2018 , the Company had 11 outstanding interest rate swap agreements, which were associated with $597.0 million of debt, that were designated as cash flow hedges of interest rate risk. Certain of the Company’s variable-rate borrowings are not hedged, and therefore, to an extent, the Company has on-going exposure to interest rate movements. The effective portion of 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. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. For the three months ended March 31, 2018 and 2017 , there was no hedge ineffectiveness. The Company expects no hedge ineffectiveness in the next 12 months. The following table summarizes the location and fair value of the cash flow hedges on the Company’s condensed consolidated balance sheets: Fair Value as of Notional Balance Sheet March 31, December 31, (in thousands) Interest rate swaps $ 596,980 Other assets $ 21,856 $ 16,872 The following table presents the effect of the Company’s cash flow hedges on the Company’s condensed consolidated financial statements: For the Three Months (in thousands) 2018 2017 Interest rate swaps: Income recognized in AOCI (effective portion) $ 5,792 $ 1,355 (Income) loss reclassified from AOCI into income (effective portion) (808 ) 195 Net other comprehensive income $ 4,984 $ 1,550 |
