2 COVID - 19 VIRUS DEVELOPMENTS The World Health Organization declared COVID - 19 virus to be a global pandemic on March 11, 2020. T he rapid spread of the COVID - 19 virus in the United States invoked various Federal and State Authorities to make emergency declarations and issue executive orders to limit the spread of disease. Concerns about the spread of the disease and its anticipated negative impact on economic activity, severely disrupted both domestic and international financial markets. As the COVID - 19 events unfolded throughout the first quarter of 2020, the Company implemented various plans, strategies and protocols to protect its employees, maintain services for customers, assure the functional continuity of its operating systems, controls and processes, and mitigate financial risks posed by changing market conditions. Although there is a high degree of uncertainty around the magnitude and duration of the economic impact of the COVID - 19 pandemic, the Company’s management believes that its financial position, including high levels of capital and liquidity, will allow it to successfully endure the negative economic impacts of the crisis .
