Commitments and Contingencies COVID-19 The COVID-19 pandemic has led to severe disruptions in general economic activities, as businesses and federal, state, and local governments take increasingly broad actions to mitigate this public health crisis. While we have experienced some delays related to final third-party validation of certain of our products and product rollouts by customers using PURE Control, we have not experienced a material disruption to our business. In addition, we previously benefited from increased demand from our customers for our PURE Hard Surface product due to a focus on surface disinfecting in response to attempting to prevent COVID-19 transmission. We subsequently experienced an abatement in such demand and cannot assure you that demand will stabilize. Additionally, we are beginning to experience supply chain issues with our various plastic packaging configurations and citric acid. Further, on a go-forward basis, we cannot guarantee the overall economic conditions will not affect our business, as these conditions may significantly negatively impact all aspects of our business. Our business is dependent on the continued health and productivity of our employees, including our sales staff and corporate management team. Additionally, our liquidity could be negatively impacted if these conditions continue for a significant period of time and we may be required to pursue additional sources of financing to obtain working capital, maintain appropriate inventory levels, and meet our financial obligations. Currently, capital and credit markets have been disrupted by the crisis and our ability to obtain any required financing is not guaranteed and largely dependent upon evolving market conditions and other factors. Depending on the continued impact of the crisis, further actions may be required to improve our cash position and capital structure. The extent to which the COVID-19 pandemic ultimately impacts our business, sales, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration and spread of the outbreak, its severity, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions resume and, more specifically, the effect it has on our customers and suppliers. Even after the COVID-19 pandemic has subsided, we may experience significant impacts to our business as a result of its global economic impact, including any economic downturn or recession that has occurred or may occur in the future.
