The Company may be involved from time to time in legal proceedings, claims and assessments arising from the ordinary course of business. Such matters are subject to many uncertainties, and outcomes are not predictable with assurance. During 2022, a former employee who was terminated in 2021 brought an age discrimination claim against the Company. During the fourth quarter of 2023, the Company settled the claim with the former employee. The Company deemed it probable that its insurance company would pay its share of the claim. As a result of this assumed gain contingency, the Company reduced its accrual to an amount that is not expected to be covered by insurance, and recorded a liability of approximately $55,000 for severance and legal expenses as of December 31, 2023. The settlement was paid and all insurance proceeds were received during the three months ended March 31, 2024. There is no other material litigation against the Company at this time.

The Company has a non-cancelable sublease agreement for its corporate headquarters in Boston, Massachusetts, which expires in January 2025 and a lease agreement for office space in Fort Worth, TX. which expires in December 2025. In August 2024, the Company entered into a new lease agreement for its new corporate headquarters and manufacturing facility in Burlington, Massachusetts, which the Company expects to begin occupying by the end of 2024, with a term of approximately 88 months following the rent commencement date. The Company has the option to extend the new lease for an additional five years, subject to certain conditions being satisfied. Under the new lease, the Company provided a security deposit to the landlord in the form of a letter of credit for $375,000. The Company has collateralized the letter of credit with cash in a separate bank account, which is accounted for as long-term restricted cash on the condensed consolidated balance sheet. Termination options are either not included, or have expired, for the Company’s other existing operating leases. Certain arrangements have discounted rent periods or escalating rent payment provisions. Leases with an initial term of twelve months or less are not recorded on the condensed consolidated balance sheets. We recognize rent expense on a straight-line basis over the lease term.
