Investment and cash management policies have been implemented that limit deposit concentrations and limit investments to investment grade securities. The risk with respect to trade receivables is mitigated by monitoring payment terms and periodic credit evaluations we perform on our customers, the short duration of our payment terms and by the diversification of our customer base.

The extent to which the COVID-19 pandemic impacts our business, operations, financial results and financial position will depend on numerous evolving factors that the Company may not be able to accurately predict, including: the duration and scope of the pandemic; our efforts and efforts by governmental authorities to mitigate the COVID-19 pandemic, such as travel bans, shelter in place orders and business closures, and the related impact on resource allocations and manufacturing and supply chains; the impact of the pandemic on economic activity and actions taken in response; the effect on our customers' demand for our goods and services and our vendors ability to supply us with raw materials; the impact of providing a safe working environment to our employees, our ability to sell and provide our goods and services, which may be limited as a result of travel restrictions and people working from home; the ability of our customers to pay for our goods and services; and any closures of our offices and facilities and our customers' offices and facilities. Customers may also slow down decision-making, delay planned work or seek to terminate existing agreements.</span></div>The Company has assessed various accounting estimates and other matters, including those that require consideration of forecasted financial information, in context with the unknown future impacts of COVID-19 using information that is reasonably available to the Company at this time. As additional information becomes available, the future assessment of these estimates, including expectations at the time regarding the duration, scope and severity of the pandemic, as well as other factors, could materially adversely affect the consolidated financial statements in future reporting periods.
