The COVID-19 outbreak in the United States has caused business disruption through mandated and voluntary closing of various businesses. While the disruption is currently expected to be temporary, there is considerable uncertainty around the duration of the closings and the impact of the pandemic on our business. Therefore, the Company expects this matter to continue to negatively impact its operating results in future periods. However, the full financial impact and duration cannot be reasonably estimated at this time.
