During periods of slowing economic activity, our customers may reduce their demand for our products, technology and professional services, which would reduce our sales, and our business, operating results and financial condition may be adversely affected. The global and domestic economies continue to face a number of economic challenges, including threatened sovereign defaults, credit downgrades, restricted credit for businesses and consumers and potentially falling demand for a variety of products and services. These developments, or the perception that any of them could occur, could result in longer sales cycles, slower adoption of new technologies and increased price competition for our products and services. We could also be exposed to credit risk and payment delinquencies on our accounts receivable, which are not covered by collateral.
Significant portions of our business are conducted outside the markets in which our products and solutions are manufactured or generally sold, and accordingly, we often export a substantial number of products into such markets. We may, therefore, be denied access to potential customers or suppliers or denied the ability to ship products from any of our subsidiaries into the countries in which we currently operate or wish to operate, as a result of economic, legislative, political and military conditions, including hostilities and acts of terrorism, in such countries.
In particular, there is currently significant uncertainty about the future relationship between the U.S. and various other countries, with respect to trade policies, treaties, government regulations, and tariffs. For example, the recent imposition of tariffs and/or changes in tariffs on various products by the U.S. and other countries, including China and Canada, have introduced greater uncertainty with respect to trade policies and government regulations affecting trade between the U.S. and other countries, and new and/or increased tariffs have subjected, and may in the future subject, us to additional costs and expenditure of resources. Major developments in trade relations, including the imposition of new or increased tariffs by the U.S. and/or other countries, and any emerging nationalist trends in specific countries could alter the trade environment and consumer purchasing behavior which, in turn, could have a material effect on our financial condition and results of operations. While the U.S. and China recently signed a "phase one" trade deal on January 15, 2020 to reduce planned increases to tariffs, concerns over the stability of bilateral trade relations remain. In addition, the UK's exit from the European Union on January 31, 2020, known as Brexit, and the ongoing negotiations of the future trading relationship between the UK and the European Union during the transition period set to end December 31, 2020 have yet to provide clarity on what the outcome will be for the UK or Europe. Changes related to Brexit could subject us to heightened risks in that region, including disruptions to trade and free movement of goods, services and people to and from the UK, disruptions to the workforce of our business partners, increased foreign exchange volatility with respect to the British pound and additional legal, political and economic uncertainty. If these actions impacting our international distribution and sales channels result in increased costs for us or our international partners, such changes could result in higher costs to us, adversely affecting our operations, particularly as we expand our international presence.
We may also be required in the future to increase our reserves for doubtful accounts. In addition, the fair value of some of our assets may decrease as a result of an uncertain economy and as a result, we may be required to record impairment charges in the future. If global economic and market conditions or economic conditions in key markets remain uncertain or weaken further, our financial condition and operating results may be materially adversely affected.
The spread of novel strain of coronavirus, COVID-19, may adversely affect our business operations and financial condition.
In December 2019, an outbreak of COVID-19 was reported in Wuhan, China. On March 11, 2020, the World Health Organization declared COVID-19 a global pandemic. This highly contagious disease has spread to most of the countries in the world and throughout both Israel and the United States, creating a serious impact on our customers, workforces, and suppliers, disrupting economies and financial markets, and potentially leading to a world-wide economic downturn. It has caused a disruption of the normal operations of many businesses, including the temporary closure or scale-back of business operations and the imposition of either quarantine or remote work or meeting requirements for employees, either by government order or on a voluntary basis. The pandemic may adversely affect our customers' ability to perform their missions and is in many cases disrupting their operations. It may also impact the ability of our subcontractors, partners, and suppliers to operate and fulfill their contractual obligations, and result in an increase in their costs and cause delays in performance. These supply chain effects, and the direct effect of the virus and the disruption on our operations, may negatively impact both our ability to meet customer demand and our revenue and profit margins. Both Israel and the United States have imposed quarantines and restrictions on travel and mass gatherings and curtailed and limited non-essential works in an attempt to slow the spread of the virus. Some of our employees are quarantined and in some cases, are working remotely due either to safety concerns and using various technologies to perform their functions. We may encounter delays or changes in customer demand, particularly if government funding priorities change. Additionally, the disruption and volatility in the global and domestic capital markets may increase the cost of capital and limit our ability to access capital. While the ultimate impact of the spread of COVID-19 is highly uncertain and subject to change, if protective or preventative measures expand, we may experience a material adverse effect on our business operations, revenues and financial condition.
