The Company has entered into two operating leases from which it conducts its business.

With respect to SINTX operations, the Company leases 29,534 square feet of office, warehouse and manufacturing space under a single operating lease. This lease expires at the end of 2024. The lease has two five-year extension options.

On August 19, 2021, the Company, on behalf of SINTX Armor, entered into an Industrial Lease Agreement (the “SINTX Armor Lease”) pursuant to which the Company has agreed to lease approximately 10,936 square feet of office and manufacturing space from which SINTX Armor will conduct its operations. The term of the SINTX Armor Lease is 122 months through October 2031.

Leases with an initial term of 12 months or less are not recorded on the balance sheet. Lease expense is recognized on a straight-line basis over the term of the lease. The Company accounts for lease components separately from the non-lease components. The depreciable life of the assets and leasehold improvements are limited by the expected lease term.

As of March 31, 2022, the operating lease right-of-use assets totaled approximately $2.3 million, and the operating lease liability totaled approximately $2.3 million. Non-cash operating lease expense during the three months ended March 31, 2022 and 2021, totaled approximately $0.1 and $0.1 million, respectively. As of March 31, 2022, the weighted-average discount rate for the Company’s operating lease was 6.5%.
