The Company leases office and warehouse space primarily in four locations: Del Mar, CA; Hayward, CA; San Diego, CA and Edwardsville, IL. As each contract does not meet any of the criteria for financing lease classification, the Company has determined that each lease arrangement should be classified as an operating lease.

On August 12, 2022, the Company entered into an agreement (the “Lease”) with Liberty Industrial Park, LLC (“Landlord”) pursuant to which the Company leases 6,627 square feet of industrial space in San Diego, California from Landlord. The Lease has a commencement date of September 1, 2022. The Lease provides for an initial monthly base rent of $11,266, which increases on an annual basis to $13,180 per month in the final year. In addition, the Company is obligated to pay its share of maintenance costs of common areas.

The Company’s leases generally do not provide an implicit rate, and, therefore, the Company uses its incremental borrowing rate as the discount rate when measuring operating lease liabilities. The incremental borrowing rate represents an estimate of the interest rate the Company would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of a lease within a particular currency environment. The Company used its incremental borrowing rate as of January 1, 2019 for operating leases that commenced prior to that date. As of January 1, 2019, the Company’s incremental borrowing rate was 5.25%. For leases commencing after January 1, 2019 the Company uses its incremental borrowing rate at time of commencement. On April 1, 2021 and September 1, 2022, the Company’s incremental borrowing rate was 4.95% and 5.5%, respectively. The weighted average remaining lease term for operating leases is 5.0 years and the weighted average discount rate is 5.1%.

Lease expense for leases determined to be operating leases is recognized on a straight-line basis over the lease term. For 2022 and 2021, lease expense was approximately $0.7 million and $0.5 million respectively.
