LEASES |
LEASES | (12) LEASES The Company categorizes leases at their inception as either operating or financing leases. Leases include various office and warehouse facilities which have been categorized as operating leases, while certain equipment is leased under financing leases. During March 2022, the Company entered into a lease agreement for approximately 4,162 square feet of office space for the operations of ZMS in Boulder, Colorado. The lease began on April 1, 2022 and will run through April 1, 2025. The rent and common area maintenance charges are equal to $17.00 per square foot with annual increases of 3%. Upon lease commencement, the Company recorded an operating lease liability and corresponding right-of-use asset for $0.2 million each. During February 2023, the Company entered into a lease agreement for approximately 41,427 square feet of office space for the operations of ZMS in Englewood, CO. The lease commences on July 1, 2023 and runs through December 31, 2028. At the expiration of the lease term the Company has the option to renew the lease for one additional five-year period. The Company is entitled to rent abatements for the first six months of the lease and tenant improvement allowances. Payments based on the initial rate of $24.75 per square foot begin in January 2024. The price per square foot increases by an additional $0.50 during each subsequent twelve-month period of the lease after the abatement period. Upon lease commencement, the Company recorded an operating lease liability of $4.2 million and a corresponding right-of-use asset for $2.8 million. The Company’s operating leases do not provide an implicit rate, and therefore the Company uses its incremental borrowing rate as the discount rate when measuring the lease liability. 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. The Company’s weighted average borrowing rate was determined to be 4.78% for its operating lease liabilities. The Company’s equipment lease agreements have a weighted average rate of 2.72% which was used to measure its finance lease liability. As of December 31, 2023, the Company’s operating and financing leases have a weighted average remaining term of 4.32 years and 3.98 years, respectively. The table below reconciles the undiscounted future minimum lease payments under the Company’s operating and finance leases to the total operating and capital lease liabilities recognized on the consolidated balance sheets as of December 31, 2023 (in thousands): ​
