Lease terminates						The stated term of the lease commenced on June 1, 2023 and terminates on September 30, 2033, ten years and four months. The lease term is based on the non-cancellable period in the lease agreement. There are two options to extend the lease, each for a term of five years; however, the extension options were not included in the measurement of the right-of-use asset and lease liability because it is not reasonably certain that the Company will exercise such extension options.
