9. COVID- 19   

In

December 2019,

a coronavirus (COVID-

19

) was reported in China and in

January 2020,

the World Health Organization (WHO) declared it a Public Health Emergency of International Concern. In

March 2020,

the WHO declared it a global pandemic. COVID-

19

continued to spread globally, directly impacting worldwide economic activity and financial markets. The extent of the COVID-

19

impact to future operational and financial performance will depend on the duration and spread of the outbreak, related public health measures, and their impact on the macroeconomy. While the Company expects this matter to negatively impact the Company's financial condition, results of operations, or cash flows, the extent of the financial impact and duration cannot be reasonably estimated at this time, as

none

of these impacts can be predicted with certainty.
