Lessee, Operating Leases [Text Block] | E. Leases We currently lease our Vista, California product manufacturing facility and Lugano, Switzerland product manufacturing and support facilities. On July 18, 2023, we entered into a Fourth Amendment to the Lease of our Vista, California manufacturing facility. The Fourth Amendment extended the term of the Lease by an additional ten years and five months commencing April 1, 2024. The amended lease covering two buildings and approximately 162,000 square feet resulted in an increase in base rent to $1.50 per square foot, after five free months of base rent beginning at the commencement of the extended term. NAI is constructing substantial improvements to the facilities including but not limited to installation of an approximately $2.3 million solar electrical generating system on both buildings, and other substantial improvements. Pursuant to the Fourth Amendment, the Landlord will reimburse NAI for up to $1.1 million of these tenant improvements to the buildings. Our lease liability and Right of Use asset were both increased by approximately $25.9 million as a result of this lease extension effective on the date that the Fourth Amendment was executed. On January 26, 2024, we exercised the early termination of an apartment lease in Lugano, Switzerland. The early termination reduced the lease term by 9 years and 8 months which ended on April 30, 2024. Our lease liability and Right of Use asset were both decreased by approximately $0.3 million as a result of the early termination of the lease agreement. On January 22, 2024, we entered into a lease for a new apartment in Lugano, Switzerland. This lease is for an initial term of 27 months, beginning April 1, 2024 and ending on June 30, 2026. Our leases are classified as operating leases. Substantially all our operating leases are comprised of payments for the use of manufacturing and office space. We have no leases classified as finance leases. As of September 30, 2025, the weighted average remaining lease term for our operating leases was 8.3 years and the weighted average discount rate for our operating leases was 5.94%. As of June 30, 2025, the weighted average remaining lease term for our operating leases was 8.6 years and the weighted average discount rate was 5.94%.
