Until the additional $70.0 million, net of a $350,000 discount, was drawn in March 2019, the Borrowers were assessed a fee on the undrawn amounts. This fee amounted to $0.4 million in the first quarter of 2019.

At June 30, 2019, there was $14.0 million outstanding on the revolving credit facility; no amount was outstanding as of December 31, 2018. The variable interest rate on the revolving credit facility was 7.4% at June 30, 2019. Undrawn commitment for a letter of credit under the revolving credit facility was approximately $0.1 million.

As a result of the Third Amendment, borrowings under the Senior Credit Agreement are subject to an applicable margin, or percentage per annum, equal to: (i) with respect to Initial Term Loans, (a) for LIBOR Rate Loans, 5.00% per annum and (b) for Base Rate Loans, 4.00% per annum; and (ii) with respect to Revolving Loans (a) for LIBOR Rate Loans and Letter of Credit fees, 5.00% per annum, (b) for Base Rate Loans, 4.00% per annum, and (c) for unused commitment fees, 0.50% per annum.

Under the Senior Credit Agreement, the Borrowers are required to make quarterly principal payments of approximately $1.0 million. Additionally, the Borrowers may be obligated to make certain additional mandatory prepayments based on excess cash flow, as defined in the Senior Credit Agreement. No such prepayment was due for the year ended December 31, 2018.

Contractual principal payments for long-term debt, excluding amounts outstanding on the revolving credit agreement, due after June 30, 2019 are as follows:
