Debt Disclosure [Abstract] |
CREDIT FACILITY | 9. CREDIT FACILITY The Company’s current and long-term debt obligation consists of amounts the Company is obligated to repay under the credit facility with Hercules Capital, Inc. (Hercules). In March 2019, the Company entered into a Loan and Security Agreement (Loan and Security Agreement or Hercules Credit Facility) with Hercules and several banks and other financial institutions or entities, from time-to-time parties thereto (collectively, referred to herein as Lender), providing for a term loan of up to $60.0 million, subject to the satisfaction of certain conditions contained therein, that is secured by a lien covering all of the Company’s assets, other than the Company’s intellectual property. The Loan and Security Agreement provided for (i) an initial term loan advance of up to $5.0 million at the Company’s option, which expired unutilized on April 15, 2019; (ii) three additional term loan advances of up to $15.0 million each, at the Company’s option, available to the Company upon the occurrence of certain pre-specified funding conditions prior to September 30, 2019 (2019 Tranche), March 31, 2020 (2020 Tranche), and March 31, 2021 (2021 Tranche); and (iii) a final additional term loan advance (Fourth Loan Tranche) of up to $10.0 million prior to December 31, 2021, at the Company’s option, subject to approval by the Lender’s investment committee. The 2019 Tranche was drawn down in full by the Company in September 2019 and the 2020 Tranche and 2021 Tranche expired unutilized prior to the Company satisfying the funding conditions for such tranche. On April 20, 2021, the Company entered into the First Amendment to the Loan and Security Agreement (First Amendment). The First Amendment, among other things, (i) increased the Fourth Loan Tranche from $10.0 million to $20.0 million and extended the deadline for drawing down the Fourth Loan Tranche to July 1, 2022; (ii) lowered the variable per annum rate of interest on borrowings under the Loan and Security Agreement from the greater of (a) 9.10% and (b) the prime rate (as reported in the Wall Street Journal or any successor publication thereto) plus 3.10% to the greater of (x) the Prime Rate (as defined in the Loan and Security Agreement) plus 3.10% or (y) 8.60%; (iii) extended the expiration of the period in which interest-only payments on borrowings under the Loan and Security Agreement are required from May 1, 2021 to July 1, 2022; and (iv) following the satisfaction of certain conditions, which conditions were satisfied in April 2021, further extended the expiration of the interest-only period and the deadline for drawing down the Fourth Loan Tranche to May 1, 2023. Repayment of the aggregate outstanding principal balance of the term loan, in monthly installments, commences upon expiration of the interest-only period and continues through October 1, 2023 (Maturity Date). The First Amendment was determined to be a modification in accordance with FASB ASC Topic 470 Debt, and did not result in extinguishment. On December 22, 2022, the Company entered into the Second Amendment to the Loan and Security Agreement (Second Amendment), which became effective as of December 31, 2022 (Second Amendment Effective Date). The Second Amendment, among other things, (i) extended the expiration of the period in which interest-only payments on borrowings under the Loan and Security Agreement are made from May 1, 2023 to May 1, 2024; (ii) extended the Maturity Date from October 1, 2023 to October 1, 2024; (iii) extended the availability of the Fourth Loan Tranche commitment of $20 million, which remained conditioned on approval by the Lenders’ investment committee, from May 1, 2023 to May 1, 2024; and (iv) amended the Prepayment Charge (as defined therein) to equal 0.75% of the amount prepaid during the 12-month period following the Second Amendment Effective Date, and 0% thereafter. In addition, a supplemental end of term charge of $292,500 (Supplemental End of Term Charge) shall be due on the earlier of (a) the Maturity Date, as amended, or (b) repayment of the aggregate amount of advances under the Loan and Security Agreement. The initial end of term charge of $1,042,500 (End of Term Charge) was paid on October 2, 2023. On April 29, 2024, the Company entered into the Third Amendment to the Loan and Security Agreement (Third Amendment). The Third Amendment, among other things, extended the expiration of the period in which interest-only payments on borrowings under the Loan and Security Agreement are made from May 1, 2024 to October 1, 2024. On May 1, 2024, the Fourth Loan Tranche commitment expired unutilized. The Second and Third Amendments were determined to be modifications in accordance with FASB ASC Topic 470 Debt, and did not result in extinguishment. On September 30, 2024, the Company entered into the Fourth Amendment to the Loan and Security Agreement (Fourth Amendment). The Fourth Amendment, among other things, (i) extended the expiration of the period in which interest-only payments on borrowings under the Loan and Security Agreement are made from October 1, 2024 to April 1, 2026; (ii) extended the Maturity Date from October 1, 2024 to April 1, 2026; and (iii) amended the term loan interest rate to be the greater of (a) the Prime Rate (as defined in the Loan and Security Agreement) plus 3.10%, or (b) 11.10%. In addition, a supplemental end of term charge of $300,000 (Second Supplemental End of Term Charge) shall be due on the earlier of (a) the Maturity Date, as amended, or (b) repayment of the aggregate amount of advances under the Loan and Security Agreement. The Supplemental End of Term Charge of $292,500 was paid on October 1, 2024. The Fourth Amendment was determined to be a modification in accordance with FASB ASC Topic 470 Debt, and did not result in extinguishment. On October 28, 2024, the Company entered into the Fifth Amendment to the Loan and Security Agreement (Fifth Amendment). The Fifth Amendment introduces, among other things, new definitions to include holding investments in a wholly owned subsidiary structured as a Massachusetts Security Corporation. In connection with the Hercules Credit Facility, the Company has incurred; a commitment charge of $25,000, transaction costs of $273,186, a fee of $375,000 upon closing, the End of Term Charge, which was paid in October 2023, and the Supplemental End of Term Charge, which was paid in October 2024. In addition, the Company will be required to pay the Second Supplemental End of Term Charge. The fees and transaction costs are amortized to interest expense from 2019 through the Maturity Date using the effective interest method. Using the effective interest method, the End of Term Charge was amortized to interest expense from 2019 through October 2023, the Supplemental End of Term Charge was amortized to interest expense from December 2022 through October 2024, and the Second Supplemental End of Term Charge is amortized to interest expense from September 2024 through the Maturity Date. The effective interest rate was 13.3% at September 30, 2024. At the Company’s option, the Company may elect to prepay all, but not less than all, of the outstanding term loan by paying the entire principal balance and all accrued and unpaid interest thereon, plus all fees and other amounts due under the Loan and Security Agreement as of the date of such prepayment. As of September 30, 2024, $15 million has been funded under the Loan and Security Agreement and no additional amounts were available to the Company for borrowing.
