As of March 31, 2022, 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.
