The majority of our manufacturing and distribution facilities are in Mexico, China and other countries in Asia Pacific, Eastern and Western Europe, South America and Northern Africa. We also purchase raw materials and other supplies from many different countries around the world. For the year ended December 31, 2023, approximately 65% of our net revenue came from sales outside the U.S. International operations are subject to certain risks inherent in doing business globally, including:
- exposure to local economic, political and labor conditions;- unexpected changes in laws, regulations, economic and trade sanctions, trade or monetary or fiscal policy, including interest rates, foreign currency exchange rates and changes in the rate of inflation in the U.S. and other countries;- tariffs, quotas, customs and other import or export restrictions and other trade barriers;- expropriation and nationalization;- difficulty of enforcing agreements, collecting receivables and protecting assets through certain non-U.S. legal systems;- reduced technology, data or intellectual property protections;- limitations on repatriation of earnings;- withholding and other taxes on remittances and other payments by subsidiaries;- investment restrictions or requirements;- violence and civil unrest in local countries, including the conflict between Ukraine and Russia and the conflicts in the Middle East; and - compliance with the requirements of an increasing body of applicable anti-bribery laws, including the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and similar laws of various other countries.
Additionally, our global operations may also be adversely affected by political events, terrorist events and hostilities, complications due to natural, nuclear or other disasters or the spread of an infectious disease, virus or other widespread illness. For instance, the outbreak of armed conflicts in the Middle East beginning in October 2023 has created numerous uncertainties, including the risk that the conflicts spread to the broader region, and their impact on the global economy and supply chains.
In addition, the conflict between Ukraine and Russia, which began in February 2022, has had, and is expected to continue to have, negative economic impacts to both countries and to the European and global economies. In response to the conflict, the European Union ("the E.U."), the U.S. and other nations implemented broad economic sanctions against Russia. These countries may impose further sanctions and take other actions as the situation continues. While the sanctions announced to date have not had a material adverse impact on us, any further sanctions imposed or actions taken by these countries, and any retaliatory measures by Russia in response, including restrictions on energy supplies from Russia to countries in the region and asset expropriations, could increase our costs, reduce our sales and earnings or otherwise have an adverse effect on our operations.
Ukraine and Russia are significant global producers of raw materials used in our supply chain, including copper, aluminum, palladium and neon gases. Disruptions in the supply and volatility in the price of these materials and other inputs produced by Ukraine or Russia, including increased logistics costs and longer transit times, could adversely impact our business and results of operations. The conflict has also increased the possibility of cyberattacks occurring, which could either directly or indirectly impact our operations. Furthermore, the conflict has caused our customers to analyze their and their suppliers' continued presence in the region and future customer production plans in the region remain uncertain.
We do not have a material physical presence in either Ukraine or Russia, with less than 1% of our workforce located in the countries as of December 31, 2023 and less than 1% of our net sales for the year ended December 31, 2023 generated from manufacturing facilities in those countries. However, the impacts of the conflict have adversely impacted, and may continue to adversely impact, global economies, and in particular, the European economy, a region which accounted for approximately 34% of our net sales for the year ended December 31, 2023. As a result of the conflict, the Company ceased using certain long-lived assets in Ukraine and consequently recorded non-cash impairment charges of $11 million during the year ended December 31, 2023. These charges were recorded within cost of sales in the statement of operations.
We continue to monitor the situation and will seek to minimize its impact to our business, while prioritizing the safety and well-being of our employees located in both countries and our compliance with applicable laws and regulations in the locations where we operate. Any of the impacts mentioned above, among others, could adversely affect our business, business opportunities, results of operations, financial condition and cash flows.
In addition, the global spread of COVID-19, which originated in late 2019 and was later declared a pandemic by the World Health Organization in March 2020, caused certain governmental authorities worldwide to initiate "lockdown" orders for all non-essential activities, which at times, included extended shutdowns of businesses in the impacted regions. This includes the lockdowns in China that occurred in 2022, as discussed further above. This or any further widespread public health crises in China or any other country in which we operate could result in social, economic and labor instability. These uncertainties could have a material adverse effect on the continuity of our business and our results of operations and financial condition.
Effective January 1, 2024, the government of Mexico implemented a country-wide statutory minimum wage increase of 20%. Additionally, the government of Mexico has indicated it may implement other labor reforms, such as a bill to shorten the work week from 48 to 40 hours. While management has implemented measures to mitigate the impact of these labor reforms on our cost structure, we cannot predict the ultimate future impact on our business.
Existing free trade laws and regulations, such as the United States-Mexico-Canada Agreement, provide certain beneficial duties and tariffs for qualifying imports and exports, subject to compliance with the applicable classification and other requirements. Changes in laws or policies governing the terms of trade, and in particular increased trade restrictions, tariffs or taxes on imports from countries where we manufacture products, such as China and Mexico, could have a material adverse effect on our business and financial results. For example, in October 2022, the U.S. government imposed additional export control restrictions targeting the export, re-export or transfer of, among other products, certain advanced computing semiconductors, semiconductor manufacturing items and related technology to China, which could further disrupt supply chains and adversely impact our business. Furthermore, management continues to monitor the volatile geopolitical environment to identify, quantify and assess proposed or threatened duties, taxes or other business restrictions which could adversely affect our business and financial results.
Increasing our manufacturing footprint in Asian markets, including China, and our business relationships with Asian automotive manufacturers are important elements of our long-term strategy. In addition, our strategy includes increasing revenue and expanding our manufacturing footprint in lower-cost regions. As a result, our exposure to the risks described above may be greater in the future. The likelihood of such occurrences and their potential impact on us vary from country to country and are unpredictable.
