Concentrations, Risks and Uncertainties	Note 11. Concentrations, Risks and Uncertainties Greystone derived approximately 87% and 85% of its total sales from four customers (three in fiscal year 2019) in fiscal years 2020 and 2019, respectively. The loss of a material amount of business from one or more of these customers could have a material adverse effect on Greystone. Greystone purchases damaged pallets from its customers at a price based on the value of the raw material content in the pallet. A majority of these purchases, totaling $1,409,045 and $1,249,653 in fiscal years 2020 and 2019, respectively, is from one of its major customers. COVID-19 The recent global outbreak of COVID-19 has created much uncertainty in the marketplace, and the full economic impact, duration and spread of the COVID-19 virus is uncertain and difficult to predict at this time considering the rapidly evolving landscape. To date, the demand for Greystone’s products has not been affected as Greystone’s pallets are generally used logistically by essential entities. Going forward, the major issue that Greystone has incurred is maintaining adequate work force to meet demand for pallets. While there has not been a reported case of COVID-19 at Greystone, the virus has impacted the overall workforce in the area as recruiting new employees has slowed, and a portion of the employees have opted to remain home for protection. Management is currently unable to estimate the impact of this economic event on its future financial position, results of operations and cash flows. Therefore, Greystone can give no assurances that this event will not have a material adverse effect on its financial position or results of operations. If the COVID-19 outbreak continues to evolve causing disruption to our workforce, customers and vendors, this economic event could have a material adverse effect on Greystone’s business, results of operations, financial condition and cash flows. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (CARES) Act was signed into law providing certain economic aid packages for small business. Greystone qualifies as a small business under CARES and has submitted an application for funding under the Paycheck Protections Program.
