Because of the numerous risks and uncertainties associated with product development and commercialization, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve or maintain profitability. Until such time, if ever, as we can generate substantial revenue sufficient to achieve profitability, we expect to finance our operations through a combination of equity offerings, debt financings and strategic alliances. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all. If we are unable to raise capital or enter into such agreements as, and when, needed, we may have to significantly delay, scale back or discontinue the further development and commercialization efforts of one or more of our products, or may be forced to reduce or terminate our operations.
We believe that our existing cash and cash equivalents and revenue from product and service, will enable us to fund our operating expenses, capital expenditure requirements and debt service payments for at least the next 12 months. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. See “Liquidity and Capital Resources.”
COVID-19
In December 2019, a novel strain of coronavirus, or COVID-19, emerged in Wuhan, Hubei Province, China. Less than four months later, in March 2020, the World Health Organization declared COVID-19 a pandemic. The impact of this pandemic has been and will likely continue to be extensive in many aspects of society, which has resulted in and will likely continue to result in significant disruptions to the global economy, as well as businesses and capital markets around the world.
In 2021, we experienced extended lead times on our supply chain, limitations on travel for our employees and customers, and delays in product installations, trainings, or shipments to and from affected countries. In 2022, we are continuing to see these impacts, which also include lockdowns in China related to the COVID-19 pandemic.
We do not yet know the net impact that the COVID-19 pandemic may have on our business and cannot guarantee that it will not be materially negative. For example, in 2021, we recorded an increase to our allowance for doubtful accounts of $1.7 million for a customer in the Middle East where due to the credit and economic conditions, including the impact of COVID-19, we determined that it is probable that collection will not occur. Although we continue to monitor the situation and may adjust our current policies as more information and public health guidance become available, the ongoing effects of the COVID-19 pandemic and/or the precautionary measures that we have adopted may create operational and other challenges, any of which could harm our business and results of operations. While we maintain an inventory of finished products and raw materials used in our products, a prolonged pandemic could lead to shortages in the raw materials necessary to manufacture our products. If we experience a prolonged disruption in our manufacturing, supply chains or commercial operations, or if demand for our products or our customers’ ability to make payments is significantly reduced as a result of the COVID-19 pandemic, we would expect to experience a material adverse impact on our business, financial condition, results of operations and prospects.
Historically, a significant portion of our field sales, customer training events and other application services have been conducted in person, and the rollout of our new products has historically been supported by our participation at industry conferences. Currently, as a result of the work and travel restrictions related to the COVID-19 pandemic, and the precautionary measures that we have adopted, a significant portion of our field sales and professional services activities continue to be conducted remotely, which has resulted in a decrease in our travel expenditures. However, we have recently permitted certain of our employees to travel to our customers and industry conferences where permitted by local authorities, and expect that our travel expenditures will also begin to increase. Any prolonged restrictive measures put in place in order to control the spread of COVID-19, including new variants, or other adverse public health developments in any of our targeted markets may have a material and adverse effect on our business operations and results of operations. We do not yet know the extent of the negative impact of such restrictions and precautionary measures, including the lifting of our travel restrictions in limited circumstances, on our ability to attract new customers or retain and expand our relationships with existing customers over the near and long term.
Factors Affecting Our Performance
We believe that our financial performance has been and in the foreseeable future will continue to be primarily driven by the following factors. While each of these factors presents significant opportunities for our business, they also pose important challenges that we must successfully address to sustain our growth and improve our results of operations. Our ability to successfully address the factors below is subject to various risks and uncertainties.
