(7) Leases

The Company determines if an arrangement is an operating lease at inception. Operating leases are included in operating lease right‑of‑use assets and current and long‑term operating lease liabilities on the Company’s balance sheet. There were no long‑term operating leases as of September 30, 2023. During the quarter ended March 31, 2024, the Company renewed the lease for its office in Novato, California for an additional three years. The renewed lease will expire on July 31, 2027. The renewal created a long‑term operating lease asset recorded during the quarter ended March 31, 2024. There were no other long‑term operating leases as of September 30, 2025.

Upon renewal of the lease for its office in Novato, California, the Company recorded a right‑of‑use asset of $1.1 million on its balance sheet. Right‑of‑use assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right‑of‑use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the present value of lease payments, the Company uses its incremental borrowing rate based on the information available at the lease commencement date. The Company’s lease terms may include options to extend the lease when it is reasonably certain that it will exercise any such options. For its leases, the Company concluded that it is not reasonably certain that any renewal options would be exercised, and, therefore, the amounts are not recognized as part of operating lease right‑of‑use assets or operating lease liabilities. Leases with initial terms of 12 months or less, and certain office equipment leases that are deemed insignificant, are not recorded on the balance sheet and are expensed as incurred and included within rent expense under general and administrative expense. Lease expense related to operating leases is recognized on a straight-line basis over the expected lease terms.

The Company’s most significant leases are real estate leases of office facilities. The Company leases office space under non-cancelable operating leases. Its principal executive office is located in Novato, California, and it has additional offices in Austin, Texas, Dallas, Texas, Boston, Massachusetts, and Chapel Hill, North Carolina. Only the office lease in Novato, California has been capitalized because the other operating leases have terms of 12 months or less, including leases that are month‑to‑month in nature. Other supplemental cash flow information, lease term, and discount rate is as follows for the years ended September 30, 2025 and 2024:
