The 2020 Loan Agreement provided for a $165.0 million senior secured credit facility (the "Credit Facility"), encompassing a $130.0 million delayed draw term loan facility (the "Delayed Draw Facility") and a $35.0 million revolving loan facility (the "Revolving Loan Facility"), which replaced the Company's prior $55.0 million delayed draw term loan facility and $35.0 million revolving loan facility. The Credit Facility had a maturity date of April 17, 2025 and borrowings thereunder bored interest at variable rates depending on the Company's election, either at a base rate or at LIBOR, in each case, plus an applicable margin. Subject to the Company's leverage ratio, the applicable margin varied between 0.50% and 1.00% for base rate loans and 1.50% and 2.00% for LIBOR loans. Borrowings under the Credit Facility were secured by substantially all of the Company's and certain of its subsidiaries' assets. During the first quarter of 2020, the Company borrowed an additional $20.9 million under the Credit Facility, which consisted of $13.9 million related to Delayed Draw Term Loans, net of unamortized debt issuance cost of less than $0.1 million, and $7.0 million related to the Revolving Loan Facility, bringing the total outstanding debt to $76.0 million. Subsequent to the additional borrowings, the Company paid down the total outstanding debt on its Credit Facility of $76.0 million during the second quarter of 2020. As a result, the Company had no debt outstanding under the Credit Facility as of December 31, 2020. Net borrowings under our credit facilities totaled $54.5 million at December 31, 2019, of which $40.5 million net of unamortized debt issuance cost of $0.6 million, related to the Draw Term Loans and $14.0 million related to the Revolving Loan Facility. In connection with entering into the Credit Facility, the Company incurred $0.8 million of debt issuance cost which is capitalized on the balance sheet and amortized over the life of the Credit Facility. As of December 31, 2020, there was $1.2 million of the remaining debt issuance cost from the Credit Facility as well as fees incurred from the prior credit facilities. Interest expense and fees totaled $1.2 million, $1.0 million and $0.2 million for the years ended December 31, 2020, 2019 and 2018, respectively. There was $0.1 million accrued interest on the credit facilities as of December 31, 2020, $0.3 million of accrued interest on the credit facilities as of December 31, 2019, and less than $0.1 million of accrued interest on the credit facilities as of December 31, 2018.
