Operating Leases |  |
Operating Leases | Note 6 – Operating Leases The Company determines if a contract is, or contains, a lease at contract inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current portion of operating lease liabilities and operating lease liabilities, net of current portion in the Company’s consolidated balance sheets. Finance leases are included in property and equipment, current portion of finance lease obligations and finance lease obligations, net of current portion in the Company’s condensed consolidated balance sheets. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. In addition, ROU assets include initial direct costs incurred by the lessee as well as any lease payments made at or before the commencement date and exclude lease incentives. The Company used the implicit rate in the lease in determining the present value of lease payments. Lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Leases with a term of one year or less are generally not included in ROU assets and corresponding operating lease liabilities. In 2023, the Company entered into a lease agreement for office space in Chicago, Illinois, commencing on August 1, 2023 for a term of three years and four months and expiring on November 30, 2026. The monthly rent for August to November 2023 was abated and the Company started to make monthly rental installments from December 2023 of $12,847. The monthly rental payment increases by approximately 2% every August starting from 2024. On July 20, 2023, the Company entered into another lease agreement for laboratory facilities in Iowa City, Iowa, commencing on August 1, 2023 for a term of five years and four months and expiring on November 30, 2028. The monthly rent for August to November 2023 was abated and the Company agreed to pay a monthly rent of $8,505 ($102,060 annually) commencing December 1, 2023. In addition, the landlord agreed to provide the Company with a one-time Tenant Improvement Allowance (“TIA”) in the amount of up to, but not exceeding $50 per rentable square foot of the premises for a maximum allowance of $253,000. Pursuant to ASC Topic 842 Leases, the Company accounted for both leases as operating leases and accounted for the TIA as a lease incentive, which was estimated to be payable on December 1, 2023. The Company received the TIA from landlord in maximum amount of $253,000 on January 16, 2024 and recorded a reimbursement receivable from landlord of $253,000 as of December 31, 2023. During the year ended December 31, 2023, the Company recorded ROU assets of $663,875 and operating lease liabilities of $642,523 at the lease commencement date. The discount rate used to determine the present value is the incremental borrowing rate, estimated to be 4.57% for Chicago lease and 4.24% for Iowa City lease, respectively, as the interest rate implicit in our lease is not readily determinable. As of June 30, 2025 and December 31, 2024, operating lease ROU assets and operating lease liabilities are recorded on the condensed consolidated balance sheets as follows:
