Leases

6 Months Ended

Oct. 31, 2025

The Company accounts for its leases under FASB ASC Topic 842, Leases. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the consolidated balance sheet as both a right-of-use ("ROU") asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease, if applicable, or the Company’s incremental borrowing rate. As the Company's leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. Lease liabilities are increased by interest and reduced by payments each period, and the right-of-use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right-of-use asset result in straight-line rent expense over the lease term.
