COVID-19 Pandemic In March 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic. The rapid spread of COVID-19 caused volatility and disruption in financial markets and prompted governments and businesses to take unprecedented measures such as travel restrictions, quarantines, shelter-in-place orders, and business shutdowns. The impact of the COVID-19 pandemic continues to evolve due to, among other reasons, the emergence of additional variants or strains of COVID-19. As such, the full magnitude of the pandemic’s effect on the Company’s financial condition, liquidity, and future results of operations is uncertain. Management continues to actively monitor the Company’s financial condition, liquidity, operations, suppliers, industry, and workforce, but currently does not anticipate any material impairments as a result of COVID-19 and will continue to evaluate the impact of COVID-19 on an ongoing basis.
