Risks And Uncertainties [Abstract]
Risks and Uncertainties	12. RISKS AND UNCERTAINTIES Litigation On October 15, 2018, Varex Imaging Corporation (“Varex”) filed its original Complaint (Case No. 1:18-cv-06911) against Richardson Electronics Ltd. (“Richardson”) in the Northern District of Illinois, which was subsequently amended on November 27, 2018. Varex alleged counts of infringement of U.S. Patent Nos. 6,456,692 and 6,519,317. Subsequently, on October 24, 2018, Varex filed a motion for preliminary injunction to stop the sale of Richardson’s ALTA750^TM product. Richardson filed an opposition to the preliminary injunction. In January 2019, the Court took evidence on the preliminary injunction issue. On September 30, 2019, the Court denied Varex’s Motion for Preliminary Injunction. On August 6, 2020, Varex amended its Complaint to add claims of trade secret misappropriation and Richardson moved to dismiss that Amended Complaint on September 9, 2020. Richardson believes the lawsuit to be without merit and a loss is not probable or estimable based on the information at the time the financial statements were issued. Company Response to COVID-19 On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus originating in Wuhan, China (the “COVID-19 outbreak”) and the risks to the international community as the virus spreads globally. In March 2020, the WHO classified the COVID-19 outbreak as a pandemic based on the rapid increase in global exposure. Thereafter, most U.S. states imposed “shelter in place” directives on their populations to stem the spread of COVID-19. Of specific interest to the Company, shelter in place directives were imposed in the states of Illinois, Massachusetts and South Carolina. The shelter in place directives generally required the closure of businesses that did not provide essential functions. The Company was considered a critical supplier of products to healthcare and critical infrastructure businesses. Several of our largest customers mandated that we continue to supply parts so as not to disrupt the supply chain and their ability to serve critical industries. As such, the Company qualified as an “Essential Business”. Essential Businesses were allowed to continue to operate during shelter in place directives. We continued our manufacturing and distribution operations even when a shelter in place directive was issued. We limited the number of people in any one of our facilities by requiring only employees who could not perform their work remotely to physically work in a Company US-based facility. The Company advised all other employees that could perform their job functions remotely to do so. As such, the Company’s operations remained operational. The impact of the COVID-19 outbreak continues to evolve. As such, the full magnitude that the pandemic will have on the Company’s financial condition, liquidity and future results of operations is uncertain. Management is actively monitoring the global situation on its financial condition, liquidity, operations, suppliers, industry and workforce. As the spread of COVID-19 continues, our ability to meet customer demands for products may be impaired or, similarly, our customers may experience adverse business consequences due to COVID-19. Reduced demand for products or impaired ability to meet customer demand (including disruptions at our transportation service providers or vendors) could have a material adverse effect on our business, operations and financial performance. There was a decline in PMT sales during the first three months of fiscal 2021 as well as a decline in Canvys and Healthcare sales during the first six months of fiscal 2021. Some of these declines in sales were related to the COVID-19 global pandemic. While we had some COVID-19 related component delays impacting new product development schedules, we did not experience a major interruption in our supply chain. Given the daily evolution of the COVID-19 outbreak and the global responses to curb its spread, the Company is not presently able to estimate the effects of COVID-19 on its results of operations, financial condition or liquidity for fiscal year 2021. Company Response to CARES Act On March 27, 2020, Congress enacted the Coronavirus Aid, Relief and Economic Security (“CARES”) Act to provide certain relief as a result of the COVID-19 outbreak. The CARES Act includes provisions relating to refundable payroll tax credits, deferral of employer-side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, increased limitations on qualified charitable contributions and technical corrections to tax depreciation methods for qualified improvement property. As of November 28, 2020, the Company deferred $0.8 million of employer-side social security tax payments. The Company has estimated and recorded the overall effects of the CARES Act and does not anticipate a material change.
