Restructuring and Related Activities [Abstract] |
Restructuring Costs | Restructuring CostsIn December 2019, the Company initiated a restructuring, which included the closure of the Company's subsidiary in China, a commercial sales organization for the Company's products in China, that was substantially completed as of April 30, 2020. In fiscal year 2022, the legal closure of the Company's China subsidiary was delayed as a result of COVID-19-related shutdowns. As a result, the Company incurred operating expenses of $28,000 in its international operations related to the closure of the China subsidiary. The Company reflected all the expenses as operating expenses in the Consolidated Statement of Operations. The Company now expects the remaining administrative requirements for closure of the China subsidiary to be completed by the end of fiscal year 2023.
