For the nine months ended September 30, 2020 and 2019, revenues received from our international customers constituted approximately 47% and 41%, respectively, of our total revenue. Additionally, for the years ended December 31, 2019 and 2018,revenues received from our international customers constituted approximately 40% and 44%, respectively, of our total revenue. We expect that future revenue derived from international sources will continue to represent a significant portion of our total revenue.
To the extent that customer sales are not denominated in U.S. dollars, any royalties which are based on a percentage of the customers' sales that we receive as a result of such sales could be subject to fluctuations in currency exchange rates. In addition, if the effective price of licensed products sold by our foreign customers were to increase as a result of fluctuations in the exchange rate of the relevant currencies, demand for licensed products could fall, which in turn would reduce our royalties. We do not use financial instruments to hedge foreign exchange rate risk.
Trade-related government actions, whether implemented by the US government, China or other countries, that impose barriers or restrictions that would impact our ability to sell or ship products to certain customers may have a negative impact on our financial condition and results of operations. We cannot predict the actions government entities may take in this context and may be unable to quickly offset or effectively react to government actions that restrict our ability to sell to certain customers or in certain jurisdictions. Government actions that affect our customers' ability to sell products or access critical elements of their supply chains may result in a decreased demand for their products, which may consequently reduce their demand for our products.
We currently have international business operations in the United Kingdom, France and the Netherlands, international design operations in Canada, India and Finland, and business development operations in China, Japan, Korea, and Taiwan. Our international operations and revenue are subject to a variety of risks which are beyond our control, including:
- hiring, maintaining and managing a workforce and facilities remotely and under various legal systems, including compliance with local labor and employment laws;- non-compliance with our code of conduct or other corporate policies;- natural disasters, acts of war, terrorism, widespread global pandemics or illness, such as the current Novel Coronavirus (COVID-19), or security breaches;- export controls, tariffs, import and licensing restrictions and other trade barriers;- profits, if any, earned abroad being subject to local tax laws and not being repatriated to the United States or, if repatriation is possible, limited in amount;- adverse tax treatment of revenue from international sources and changes to tax codes, including being subject to foreign tax laws and being liable for paying withholding, income or other taxes in foreign jurisdictions;- unanticipated changes in foreign government laws and regulations;- increased financial accounting and reporting burdens and complexities;- lack of protection of our intellectual property and other contract rights by jurisdictions in which we may do business to the same extent as the laws of the United States;- potential vulnerability to computer system, internet or other systemic attacks, such as denial of service, viruses or other malware which may be caused by criminals, terrorists or other sophisticated organizations;- social, political and economic instability;- geopolitical issues, including changes in diplomatic and trade relationships, in particular with China; and - cultural differences in the conduct of business both with customers and in conducting business in our international facilities and international sales offices.
We and our customers are subject to many of the risks described above with respect to companies which are located in different countries. There can be no assurance that one or more of the risks associated with our international operations will not result in a material adverse effect on our business, financial condition or results of operations.
