Our business, operations and performance are dependent in part on worldwide economic conditions and events that may be outside of our control, such as political and social unrest, terrorist attacks, hostilities, malicious human acts, climate change, natural disasters (including extreme weather), pandemics or other major public health concerns and other similar events, and the impact these conditions and events have on the overall demand for enterprise computing infrastructure solutions and on the economic health and general willingness of our current and prospective end customers to purchase our solutions and to continue spending on IT in general. The global macroeconomic environment has been, and may continue to be, inconsistent, challenging and unpredictable due to international trade disputes, tariffs, including those recently imposed by the U.S. government on Chinese imports to the U.S., restrictions on sales and technology transfers, uncertainties related to changes in public policies such as domestic and international regulations, taxes, or international trade agreements, elections, geopolitical turmoil and civil unrests, instability in the global credit markets, uncertainties regarding the effects of the United Kingdom's separation from the European Union, commonly known as "Brexit", actual or potential government shutdowns, and other disruptions to global and regional economies and markets. Specifically, pandemics have caused and may in the future cause travel bans or disruptions, supply chain delays and disruptions, and additional macroeconomic uncertainty, and could cause various negative effects, including an inability to meet with actual or potential customers, our customers deciding to delay or abandon their planned purchases, us deciding to delay, cancel, or withdraw from user and industry conferences and other marketing events, and delays or disruptions in our or our partners' supply chains, including delays or disruptions in procuring and shipping the hardware appliances on which our software solutions run. As a result, we may experience extended sales cycles, our ability to close transactions with new and existing customers and partners may be negatively impacted, potentially significantly, our ability to recognize revenue from software transactions we do close may be negatively impacted, potentially significantly, our demand generation activities, and the efficiency and effect of those activities, may be negatively affected, our ability to provide 24x7 worldwide support to our customers may be effected, and it may continue to be more difficult for us to forecast our operating results. Any of these global economic conditions could have the effect of reducing overall IT spending and could cause our customers to modify spending priorities or delay or abandon purchasing decisions, thereby lengthening sales cycles and potentially lowering prices for our solutions and product and services offerings, and may make it difficult for us to forecast our sales and operating results and to make decisions about future investments, any of which could materially harm our business, operating results and financial condition.
