Legal proceedings may materially adversely affect our business and our results of operations, cash flows and financial condition.
We have been party to, and in the future may become subject to, legal proceedings in the operation of our business, including in respect of the implementation of our mergers and acquisitions strategy. Such legal proceedings include, but not limited to, those relating to advertising, consumer protection, employee matters, tax matters, alleged service and system malfunctions, alleged intellectual property infringement and claims relating to our contracts, licenses and strategic investments, as well as claims by or against our shareholders (present or past), directors, officers and employees.
Legal proceedings targeting our games and claiming violations of laws could occur based on the unique and particular laws of each jurisdiction, particularly as litigation claims and regulations continue to evolve. Defending ourselves against claims by third parties, or the initiation of litigation to enforce any rights that we may have against third parties, could result in substantial costs and diversion of our resources, causing a material adverse effect on our business, financial condition and results of operations.
Given the nature of our business, we may from time to time be party to various legal, administrative and regulatory inquiries, investigations, proceedings and claims that arise in the ordinary course of business. Because the outcome of such legal matters is inherently uncertain, they could have a material adverse effect on our results of operations, cash flows or financial condition.
We rely on a limited number of geographies for a significant portion of our revenues.
Although we have players across the globe, we derive a significant portion of our revenues from a limited number of countries and are dependent on access to those markets. For example, for the year ended December 31, 2021, 31.5% of our revenues were derived from users located in the United States, 24.5% of our revenues were derived from users located in Asia, with Japan and South Korea being the key drivers, and 21.6% of our revenues were derived from users located in Europe. Our ability to retain paying players depends on our success in these geographies, and if we were to lose access to these markets or experience a decline in players in these geographies for any reason, it would have a material adverse effect on our business, financial condition and results of operations.
If general economic conditions decline, demand for our games could decline. In addition, our business is vulnerable to changing economic conditions and to other factors that adversely affect the gaming industry, which could negatively impact our business.
In-game purchases involve discretionary spending on the part of consumers. Consumers are generally more willing to make discretionary purchases, including purchases of games and services like ours, during periods in which favorable economic conditions prevail. As a result, our games may be sensitive to general economic conditions and economic cycles. A reduction or shift in domestic or international consumer spending could result in an increase in our marketing and promotional expenses, in an effort to offset that reduction, and could negatively impact our business. Discretionary spending on entertainment activities could further decline for reasons beyond our control, such as natural disasters, acts of war, pandemics, terrorism, transportation disruptions or the results of adverse weather conditions. Additionally, disposable income available for discretionary spending may be reduced by unemployment, higher housing, energy, interest, or other costs, or where the actual or perceived wealth of customers has decreased because of circumstances such as lower residential real estate values, increased foreclosure rates, inflation, increased tax rates, or other economic disruptions. Any prolonged or significant decrease in consumer spending on entertainment activities could result in reduced play levels in decreased spending on our games, and could adversely impact our results of operations, cash flows and financial condition.
Our systems and operations are vulnerable to damage or interruption from natural disasters, power losses, telecommunications failures, cyber-attacks, terrorist attacks, acts of war, human errors, break-ins and similar events.
We may experience disruption as a result of catastrophic events such as natural disasters, power losses, telecommunications failures, cyber-attacks, terrorist attacks, acts of war, human errors, break-ins and similar events. In the occurrence of a catastrophic event, including a global pandemic like the ongoing COVID-19 pandemic, we may be unable to continue our operations and may endure system interruptions, reputational harm, delays in application development, lengthy interruptions in our services, breaches of data security and loss of critical data, such as player, customer and billing data as well as trade secret or other confidential information, software versions or other relevant data regarding operations, and we do not maintain insurance policies to compensate us for any resulting losses, which could have a material adverse effect on our business, financial condition and results of operations. As a result of the COVID-19 pandemic, we grant our employees the choice to work remotely. If a natural disaster, power outage,
