As of September 30, 2025, the Company concluded that its continued loss history constitutes a triggering event as described in ASC 360-10-35-21, Property, Plant, and Equipment.  The Company performed a recoverability test and concluded that future undiscounted cash flows exceed the carrying amount of the Company’s long-lived assets and therefore no impairment charge was recorded.
