Covid-19 Pandemic	2. COVID-19 PANDEMIC: In December 2019, a novel strain of coronavirus ("Covid-19") was first identified, and in March 2020, the World Health Organization categorized Covid-19 as a pandemic. The Covid-19 pandemic is affecting our customers, suppliers, service providers and employees, and the ultimate impacts of Covid-19 on our business, results of operations, liquidity and prospects are not fully known at this time. The Covid-19 outbreak has had a minimal impact on our business to date. However, the following risks and uncertainties are impacting our business: · Our key factories are located in Minnesota and Singapore. Both of these locations are subject to government mandated shelter-in-place orders. Because our operations have been deemed essential, we have been able to keep our factories up and running while the shelter-in-place mandates are in effect. We have implemented split-shifts for our factory operations to minimize the number of employees in our facilities at any given time, however, this has not affected our production capacity. Our non-factory employees are required to work remotely. To date, the shelter-in-place mandates have had a minimal impact to operations, but that could change if the pandemic worsens and is more than temporary. · Sales of some products, mainly our SQ3000 Multi-Function inspection and measurement systems and MX memory module inspection products, require customer acceptance due to performance or other criteria that is considered more than a formality. Many of our customer’s factories have remained open during the Covid-19 pandemic because they are deemed to be essential under most government shelter-in-place mandates. However, this could change if the pandemic worsens and continuing global travel restrictions could hinder our ability to obtain customer acceptances in a timely manner, and therefore impact the timing of revenue recognition. · We have experienced some supply disruptions due to the Covid-19 pandemic, mainly from suppliers not deemed essential by shelter-in-place mandates in certain countries. Key supply chain disruptions have mostly been resolved currently, but that could change significantly if the pandemic worsens and is more than temporary. To date, our on-hand inventories have been sufficient to enable us to work through any supply disruptions. Although we cannot estimate the length or gravity of the impact of the Covid-19 outbreak at this time, if the pandemic continues, it may have an adverse effect on our results of future operations, financial position and liquidity in fiscal year 2020. CARES Act On March 27, 2020, the "Coronavirus Aid, Relief and Economic Security (CARES) Act" was signed into law in the United States. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods and alternative tax credit refunds.
