On May 9, 2019, we closed on a new $350,000 unsecured credit facility that consists entirely of a revolving line of credit (the “Unsecured Revolving Line of Credit”), refinancing and terminating the previous unsecured credit facility. We have the right to increase the aggregate amount of the Unsecured Revolving Line of Credit to up to $600,000. The maturity date on borrowings outstanding under the Unsecured Revolving Line of Credit is May 9, 2023, subject to our option to extend the revolving commitment for two additional 6-month periods under certain circumstances, including the payment of an extension fee. We may prepay the Unsecured Revolving Line of Credit, in whole or in part, at any time without a prepayment fee or penalty. At our option, borrowings under the Unsecured Revolving Line of Credit will bear interest at a rate equal to either (i) the 1-month LIBOR rate plus a margin of 125 to 200 basis points, or (ii) a base rate plus a margin of 25 to 100 basis points. The applicable margin is determined based upon our total consolidated leverage ratio, as defined in the agreements. At the time of closing, based on our leverage ratio, the margin spread to LIBOR was 155 basis points. We recognized the refinance as a modification of our prior unsecured credit facility and incurred deferred financing costs of $1,129 associated with this transaction.

On April 30, 2019, we extinguished a property mortgage in the amount of $18,850 in connection with a property disposition.

On July 18, 2019, we extinguished two property mortgages in the amounts of $20,527 and $14,235, respectively, in connection with two property dispositions.
