Term Loan [Abstract] |
Term Loan | 8. Term Loan On April 28, 2020, the Company entered into a Loan and Security Agreement (the Loan Agreement) as amended on July 8, 2020, September 14, 2020, September 15, 2020, October 21, 2021 (the 2021 Loan Amendment), December 2, 2022 (the 2022 Loan Amendment) and May 30, 2023 with Banc of California (formerly known as Pacific Western Bank) to finance leasehold improvements for the facilities in Redwood City, CA and other purposes permitted under the Loan Agreement. Under the 2021 Loan Amendment, Banc of California will provide one or more Term Loans (as defined in the 2021 Loan Amendment), as well as Non-Formula Ancillary Services which shall not exceed $5.5 million in the aggregate. Non-Formula Ancillary Services are defined as automated clearinghouse transactions, corporate credit card services, letters of credit, or other treasury management services. Per the terms of the Loan Agreement, the aggregate sum of the outstanding Term Loans and Non-Formula Ancillary Services shall at no time exceed $15.0 million, which each Term Loan to be in an amount of not less than $1.0 million. On March 13, 2023, the Company and Banc of California executed a letter agreeing that, notwithstanding the covenants included in the 2022 Loan Amendment, until June 30, 2023 (i) the Company and its subsidiaries will not be required to maintain the lesser of $200 million or seventy percent (70%) of its combined balances in demand deposit accounts, money market funds and/or insured cash sweep (ICS) accounts with Banc of California and (ii) the Company must maintain its combined balances at Banc of California or its affiliates, including Pacific Western Asset Management (the Letter). On May 30, 2023, the Company further amended its Loan Agreement with Banc of California (the 2023 Loan Amendment). Pursuant to the 2023 Loan Amendment, the Company must maintain the lesser of (i) $35.0 million or (ii) all of the Company’s combined balances in demand deposit accounts, money market accounts, and/or insured cash sweep accounts with Banc of California. If the Company’s total cash and investments drop to less than $35.0 million, the 2023 Loan Amendment permits the Company to maintain cash and/or investments in one or more accounts outside of Banc of California up to a total of $2.5 million. In April 2024, the Term Loan availability under the Loan Agreement expired. The Non-Formula Ancillary Services, which shall not exceed $5.5 million in the aggregate, remained available. On November 27, 2024, the Company executed a payoff letter (the Payoff Letter) with Banc of California to repay in full all outstanding indebtedness and terminate all commitments and obligations, subject to certain exceptions, under the Loan Agreement. Under the Payoff Letter, the Company agreed to pay Banc of California approximately $10,000 in administrative fees and establish cash collateral accounts and execute pledge and security agreements to secure ancillary services provided by Banc of California. The Company paid the $10,000 administrative fees in December 2024. No termination penalty was paid in connection with the Payoff Letter. As of March 31, 2026, we have $2.9 million of restricted cash held in cash collateral accounts.
