Effect of Covid-19 Pandemic [Text Block]	16. COVID- 19 Overview: The pandemic caused by the disease COVID-19 was first reported in Wuhan, China in December 2019 and has since spread throughout the world. Financial markets have been volatile due to uncertainty with respect to the severity and duration of the pandemic. The pandemic resulted in federal, state and local governments around the world implementing increasingly stringent measures to help control the spread of the virus, including quarantines, “shelter in place” and “stay at home” orders, travel restrictions or bans, business curtailments, school closures, and other protective measures. Our aerospace segment qualified as “essential” under applicable federal guidance and state orders. The facilities have continued operations. We are enforcing social distancing and enhanced health, safety and sanitization measures in accordance with guidelines from the Center for Disease Control (the “CDC”). Our professional services operations at the Boot Hill Casino & Resort was forced to close from March 18, 2020 thru May 21, 2020. The casino reopened to the public on May 22, 2020 with reduced hours to allow for extra time for cleaning and sanitizing in accordance with CDC guidelines and limited number of games and food offerings. We are also continuing to enforce social distancing measures throughout the casino and are subject to state mandated restrictions. Since reopening the Boot Hill Casino & Resort we have experienced lower customer headcount, which has been off-set by a larger net revenue per customer. The COVID-19 pandemic impacted our business operations and financial results beginning in the fourth quarter of fiscal 2020 and continues to impact us. We face numerous uncertainties in estimating the direct and indirect effects on our present and future business operations, financial condition, results of operations, and liquidity. Due to several rapidly changing variables related to the COVID-19 pandemic, we cannot reasonably estimate future economic trends and the timing of when stability will return. As schools, businesses and the economy in general have slowly reopened, and vaccinations rates in our operating territory improve and new infections decline, we have continued to see improvements in customer headcount. However, the unpredictable nature of the pandemic could again lead to closures, decreased traffic and demand, and increased COVID-19- related operating expenses, for the foreseeable future. While COVID-19 has resulted in, and will continue to bring, significant challenges and uncertainty to our operating environment, we believe that our resilient business model and the strength of our brand and balance sheet position us well to emerge from the pandemic.
