On September 17, 2015, we entered into a credit agreement with KeyBank National Association (“KeyBank”) with respect to a $325,000 senior secured credit facility (the “Secured Credit Facility”). We incurred upfront costs of $4,722 associated with this facility that were capitalized as deferred financing costs. The Secured Credit Facility consisted of a revolving line of credit in an amount of up to $125,000 and a term loan in an amount of no less than $200,000.

On December 21, 2016, we entered into an increase agreement with KeyBank which amended the terms of the previous Secured Credit Facility. The amended agreement increased the revolving line of credit to $172,500, which reflected the conversion of a portion of the term loan line of credit, which had previously been repaid and was therefore unavailable for re-borrowing, into availability under the revolving line of credit. The amended revised Secured Credit Facility had a total capacity was $312,500. The other features of the facility remained the same.

On May 1, 2017, we entered into a $300,000 unsecured credit facility (the “Unsecured Credit Facility), refinancing and terminating the previous Secured Credit Facility. The Unsecured Credit Facility is comprised of a $50,000 term loan and a revolving commitment of up to $250,000. Additionally, we have the right to increase the aggregate amount of the Unsecured Credit Facility to up to $500,000. The maturity date on the new term loan is May 1, 2022. The maturity date on borrowings outstanding under the revolving commitment is May 1, 2021, subject to our option to extend the revolving commitment for two additional 6-month periods under certain circumstances. We may prepay the Unsecured Credit Facility, in whole or in part, at any time without prepayment fee or penalty, subject to the payment of any breakage costs associated with LIBOR borrowings and certain other conditions as set forth in the loan agreement. At our option, borrowings under the Unsecured Credit Facility will bear interest at a rate equal to either (i) the 1-month LIBOR rate plus a margin of 130 to 220 basis points, or (ii) a base rate plus a margin of 30 to 120 basis points. The applicable margin is determined based upon our total consolidated leverage ratio. In addition, we pay a fee of either 15 basis points (if greater than or equal to 50% of the revolver is used) or 25 basis points (if less than 50% of the revolver is used) on the unused portion of the revolver. The Unsecured Credit Facility requires regular interest only payments. We recognized the refinance as a partial extinguishment of our prior Secured Credit Facility and recognized a loss on extinguishment of debt of $572.

In addition to certain negative covenants, our Unsecured Credit Facility with KeyBank has financial covenants that require us to (i) maintain a consolidated leverage ratio below thresholds described in the debt agreement, (ii) maintain a minimum consolidated fixed charge coverage ratio, (iii) maintain a minimum consolidated tangible net worth, and (iv) maintain a minimum liquidity amount. Additionally, the covenants (i) limit (a) the amount of distributions that IRT can make to a percentage of Funds from Operations (as such term is described in the debt agreement), (b) the amount of recourse indebtedness that may be incurred by us, and (c) the amount of unhedged variable rate indebtedness that may be incurred by us, and (ii) require us to maintain a pool of unencumbered properties with an occupancy level of not less than 85%.

On September 17, 2015, we entered into a credit agreement with KeyBank with respect to a $120,000 senior interim term loan facility (“Interim Facility”). We incurred upfront deferred costs of $2,092 associated with this Interim Facility. On June 24, 2016, the Interim Facility was amended to replace the Interim Facility with a $40,000 senior secured term loan. Upon entering into the senior secured term loan, we borrowed $40,000, using $416 to pay closing costs and $33,512 to repay the remaining balance under the Interim Facility. The maturity date of the senior secured term loan was September 17, 2018, subject to acceleration in the event of customary events of default. The term loan required monthly interest only payments. The senior secured term loan was repaid in October 2016.

On November 20, 2017, we entered into a loan agreement for a $100,000 unsecured term loan that will mature in November 2024. We incurred upfront deferred costs of $917 associated with this facility. The unsecured term loan requires monthly interest only payments. The interest rate on the unsecured term loan is LIBOR plus a spread of 1.60% - 2.50% based on our consolidated leverage ratio. The proceeds from this loan reduced borrowings then outstanding under the revolving portion of our Unsecured Credit Facility.

On October 30, 2018, we entered into a five-year, $200,000 unsecured term loan agreement with KeyBank. The loan matures in January 2024 and bears interest at a spread over LIBOR, based on our overall leverage. At closing, the spread to LIBOR was 145 basis points. At closing, we drew $150,000 under the loan. The remaining $50,000 was drawn in February 2019. We applied proceeds of both draws to reduce outstanding borrowings under our Unsecured Credit Facility. We incurred upfront deferred costs of $821 associated with this facility.
