On June 20, 2018, SJI issued an aggregate of $475.0 million of Floating Rate Senior Notes, Series 2018D, due 2019 on the one-year anniversary of the date of initial issuance.

SJI guaranteed this facility until the closing of the Acquisition (see Notes 1 and 17). On June 28, 2018, the lenders funded the term loan facility. At the election of the Company, the term loans will bear interest at a variable base rate or a variable LIBOR. The facility contains among others, a financial covenant, limiting the ratio of total indebtedness to total capitalization of the Company (as defined in the term loan credit agreement) by no more than 0.70 to 1.0, measured at the end of each fiscal quarter. The Company was in compliance with this covenant at September 30, 2018. The April 2018 and June 2018 debt issuances were used to fund the Acquisition, which closed July 1, 2018 (see Notes 1 and 17). In August 2018, SJG retired $10.0 million of 7.97% MTN's. SJI and SJG did not issue or retire any other long-term debt during the nine months ended September 30, 2018.
