Subsequent Events [Abstract] |
Subsequent Events | Subsequent Events Subsequent events are defined as those events or transactions that occur after the balance sheet date, but before the financial statements are filed with the Securities and Exchange Commission. During the fourth quarter of fiscal 2020, the Company executed the first amendment to its operating lease at 1330 Piccard Drive in Rockville, Maryland. This amendment expands the premises ("Expansion Premises") for which the Company leases laboratory and office space and extends the existing lease by six months to match the term of the Expansion Premises lease. The Expansion Premises operating lease commencement date is June 1, 2020 and the lease expires February 28, 2029. In accordance with ASC 842, "Leases", the Company evaluated the first amendment and also performed a reassessment of the existing lease to determine the impact of the six-month term extension. The Company did not recognize rental expense under this amendment during fiscal 2020 as the Expansion Premises operating lease commencement date is during fiscal 2021. Upon the Expansion Premises operating lease commencement date, the Company will recognize an operating ROU asset and related operating lease liability of $3.8 million, respectively, related to the Expansion Premises lease. The Company will also recognize an operating ROU asset and related operating lease liability of approximately $118,000 and $125,000, respectively, related to the extension of the current lease, as well as interest and amortization expense of $7,000. On June 30, 2020, the Company terminated its operating lease at 1405 Research Boulevard in Rockville, Maryland, where it also leased laboratory and office space, in order to transition its activities from this location to the Expansion Premises, as defined above, during the first quarter of fiscal 2021. Upon lease termination, the Company will recognize a decrease in the related operating ROU asset and operating lease liability of approximately $850,000 and $926,000, respectively, as well as a gain on lease termination of $76,000.
