Long-Term Debt On February 20, 2018, we entered into a $175.0 million Loan Agreement with CRG Servicing LLC (“CRG”). Net proceeds under the Loan Agreement were $173.3 million. The Term Loans under the Loan Agreement bear interest at a rate equal to 9.5% per annum. At December 31, 2020, the effective interest rate was 10.3%. At our option, until September 30, 2023, a portion of the interest payments may be paid in kind, and thereby added to the principal. Through December 31, 2020, a portion of our interest was paid in kind, which increased the principal amount of the Term Loans to $180.9 million, net of debt discount of $1.1 million. The Term Loans have a maturity date of December 31, 2023, unless earlier prepaid. The Term Loans and paid-in-kind interest will be entirely payable at maturity. In August 2019, we entered into a second amendment to the Loan Agreement (the “Second Amendment”). The Second Amendment amended the annual net sales threshold for sales of HEPLISAV-B, revising the twelve-month measurement periods from beginning on January 1 of each year to beginning on July 1 of each year and ending on June 30, 2023. The Second Amendment also revised the fee payable upon partial prepayment or at maturity of the Term Loans from 3% to 4% of the aggregate principal amounts. In November 2020, we entered into a third amendment to the Loan Agreement (the “Third Amendment”). The Third Amendment modified the annual net sales threshold requirement to include sales of CpG 1018 and removed the annual net sales threshold requirement for the twelve-month period beginning July 1, 2020 and ending on June 30, 2021. The obligations under the Loan Agreement are secured, subject to customary permitted liens and other agreed upon exceptions, by a perfected security interest in (i) all tangible and intangible assets of the Company and any future subsidiary guarantors, except for certain customary excluded property, and (ii) all of the capital stock owned by the Company and such future subsidiary guarantors (limited, in the case of the stock of certain non-U.S. subsidiaries of the Company and certain U.S. subsidiaries substantially all of whose assets consist of equity interests in non-U.S. subsidiaries, to 65% of the capital stock of such subsidiaries, subject to certain exceptions). The obligations under the Loan Agreement will be guaranteed by each of the Company’s future direct and indirect subsidiaries (other than certain non-U.S. subsidiaries of the Company and certain U.S. subsidiaries substantially all of whose assets consist of equity interests in non-U.S. subsidiaries, subject to certain exceptions). The Loan Agreement contains customary covenants and requires us to comply with a $15.0 million daily minimum combined cash and investment balance covenant and a twelve-month period revenue requirement starting on July 1, 2019 for sales of HEPLISAV-B and CpG 1018. We recorded $19.1 million, $16.5 million and $8.8 million of interest expense related to the Term Loans during the year ended December 31, 2020, 2019 and 2018, respectively.
