Governments and businesses around the world have taken unprecedented actions to mitigate the spread of COVID-19, including but not limited to, shelter-in-place orders, quarantines, significant restrictions on travel, as well as restrictions that prohibit many employees from going to work. Our top concern is, and remains, the health and well-being of our employees around the world. To date, COVID-19 has surfaced in nearly all regions around the world and has impacted our sales channels, supply chain, manufacturing operations, workforce, and other key aspects of our operations. The outbreak and preventive measures taken to help curb the spread, including temporary plant closures in China, India, Italy and other countries where outbreaks and stay-at-home orders were most prevalent, had an adverse impact on our operations and business results for the first six months of 2020.</span></div>
