statements for a discussion of our borrowings and the terms of these debt facilities. As of September 30, 2020 and December 31, 2019, our long-term debt, including current portion, was $473.7 million and $468.2 million, respectively, which is presented net of $20.3 million and $22.2 million of deferred financing fees, respectively, in the condensed consolidated balance sheets. As of September 30, 2020, we had $1.4 million available under the current revolving credit facility. As of December 31, 2019, we had $15.4 million available under the current revolving credit facility. We may request an increase in (i) the Revolving Credit Facility and Tranche A Loans as would not cause the consolidated first lien leverage ratio, determined on a pro forma basis after giving effect to any such increase, to exceed 2.80:1.00 and (ii) the Tranche A-1 Loans, as would not cause the consolidated first lien leverage ratio, determined on a pro forma basis after giving effect to any such increase, to exceed (a) with respect to any increase, the proceeds of which will be used solely to finance an acquisition, 3.00:1.00 and (b) with respect to any other increase, 2.90:1.00, subject to the satisfaction of certain conditions in the Amended BoA Credit Agreement. We may request one or more additional term loan facilities or the increase of term loan commitments under the Amended Wilmington Credit Agreement as would not cause the consolidated total leverage ratio, determined on a pro forma basis after giving effect to any such addition and increase, to exceed 6.00:1.00, subject to the satisfaction of certain conditions in the Amended Wilmington Credit Agreement. We made $19.9 million of principal repayments under our Loan Agreements during the nine months ended September 30, 2020.
Off-Balance Sheet Arrangements
As of September 30, 2020 and December 31, 2019, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As a result, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
We limit exposure to foreign currency fluctuations by requiring payment under the majority of our licenses to be denominated in U.S. dollars. One of our license agreements is denominated in Canadian dollars. If there were an adverse change in the exchange rate from Canadian to U.S. dollars of 10%, the expected effect on net income would be immaterial.
Our earnings may also be affected by changes in LIBOR interest rates as a result of our Loan Agreements. As further discussed in Notes 4 and 8 to our accompanying unaudited condensed consolidated financial statements, we have entered into interest rate swaps to mitigate the effects of a change in LIBOR interest rates. An increase in LIBOR interest rates of one percent affecting the Loan Agreements would not have had a material effect on our results of operations during the three and nine months ended September 30, 2020 and 2019.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, under the supervision and with the participation of our Executive Chairman, Chief Financial Officer, and Senior Vice President of Finance evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of September 30, 2020, the end of the period covered by this report. Based on, and as of the date of such evaluation, the Executive Chairman, Chief Financial Officer, and Senior Vice President of Finance have concluded that our disclosure controls and procedures were effective as of September 30, 2020 such that the information required to be disclosed in our reports filed or submitted to the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and is accumulated and communicated to our management, including our principal executive officer and co-principal financial officers, as appropriate, to allow timely decisions regarding required disclosure.
