(8) Leases

The Company has an operating lease for lab space from Sanford Health (a former related party), under a lease that started in June 2014 and ran through June 2019, at which time the lease was amended to run through August 2024. This lease can be terminated with one year advance written notice. The lease is for $66,993 per month. The operating lease does not include an option to extend beyond the life of the current term. The lease does not provide an implicit rate, and, therefore, the Company used an IBR of 4.54% as the discount rate when measuring the operating lease liability. The Company estimated the incremental borrowing rate based upon comparing interest rates available in the market for similar borrowings and the credit quality of the Company.

The Company entered into a lease for office, laboratory, and warehouse space in November 2020. This lease has a 3-year term, with options to extend for three additional periods of three years each. The options were not included in the right of use calculation as it is unclear as to whether or not the location will meet the Company’s requirements beyond the next three years. The lease cost is $36,125 per month. The Company used an IBR of 4.69% as the discount rate when measuring the operating lease liability. The Company estimated the incremental borrowing rate based upon comparing interest rates available in the market for similar borrowings and the credit quality of the Company.

The Company entered into a lease for barn space for the housing of goats in April 2020. This lease has a 2-year term, with automatic renewals for a one-year period after the initial term expires until either party terminates. The options were not included in the right of use calculation, as the goat project is mostly funded by government grants, and those grants do not currently extend beyond the initial lease term. The lease cost is $665 per month for the first year, then $678 per month for the second year. The Company used an IBR of

4.08% as the discount rate when measuring the operating lease liability. The Company estimated the incremental borrowing rate based upon comparing interest rates available in the market for similar borrowings and the credit quality of the Company.

The Company has the following finance leases:

•In December 2018, the Company entered into a finance lease with Dakota Ag Properties for a new animal facility which includes the surrounding land. The facility and the land have been accounted for as separate lease components. The lease is based upon payback of $4,000,000 in construction costs, with a 20-year term at an interest rate of 8%. The monthly payment for this lease is $33,458. The Company has the option to purchase the asset at any time during the term of the lease for the balance of the unamortized lease payments.

•In December 2018, the Company entered into an equipment lease for a 12,000-gallon propane tank that is located on the Company’s animal facility. The lease is for five years, with an annual payment of $8,199. The Company has the option to purchase the asset at any time during the term of the lease for the balance of the unamortized lease payments.

•In July 2018, the Company entered into a lease agreement with a bank, for a Ruby Cell Analyzer. The lease agreement is for a five-year term. The monthly payment for this lease is $807. The Company has the option to purchase the asset at the end of the lease for $1.

•In March 2019, the Company entered into two lease agreements for laboratory equipment. The leases are each for a 3-year term and a combined monthly payment of $5,956. Both leases have a $1 purchase option at the end of the lease term.

The lease agreements do not require material variable lease payments, residual value guarantees or restrictive covenants.

The amortizable lives of the operating lease assets are limited by their expected lease terms. The amortizable lives of the finance lease assets are limited by their expected lives, as the Company intends to exercise the purchase options at the end of the leases. The following is the estimated useful lives of the finance lease assets:

Animal Facility	40 years
Equipment	3 –7 years
Land	Indefinite
