We have operations in many countries. Operations outside of the U.S. in the aggregate represent a majority of our net sales and operating income, with a particular concentration in Malaysia. In addition, although we have repatriated a substantial amount of cash since the enactment of the U.S. Tax Cuts and Jobs Act ("U.S. Tax Reform") in 2017, a significant amount of our cash balances remain held outside of the U.S., with a particular concentration in Malaysia and China. We support customers operating in various countries and purchase a significant number of components manufactured in various countries. These international aspects of our operations, which are likely to increase over time, including with any introduction of facilities in new locations, subject us to risks that could materially impact our operations and operating results, such as the following:
- economic, political or civil instability - civil or international conflicts and war, including the risk of escalation in the Russia-Ukraine war, conflict in the Middle East, escalating tensions between China and Taiwan as well as China and the U.S.
- transportation delays or interruptions - exchange rate fluctuations - potential disruptions or restrictions on our ability to access cash amounts held outside of the U.S.
- changes in labor markets, such as government-mandated wage increases, increases to minimum wage requirements, changes in union-related laws, regulations or practices, limitations on immigration or the free movement of labor or restrictions on the use of migrant workers, and difficulties in appropriately staffing and managing personnel in diverse cultures and increased public scrutiny on labor practices - customers shifting parts of their manufacturing and supply chains to different countries, including re-shoring, which may impact footprint needs and create operational disruption due to transition efforts - compliance with laws, such as the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and the European Union's (EU's) General Data Protection Regulation (the "GDPR"), applicable to companies with global operations - changing global trade regulations, particularly relating to advanced semiconductors and chip-manufacturing equipment, which may limit the ability to ship certain components or product to customers in China, support certain programs in our China operations, and source the components necessary to manufacture customer product in China - changes in the taxation of earnings in the U.S. and in other countries - reputational risks related to, among other factors, varying standards and practices among countries - changes in duty rates - significant natural disasters and other events or factors impacting local infrastructure - the effects of other international political developments, such as tariffs, embargoes, sanctions, boycotts, trade wars, energy disruptions, trade agreements and changes in trade policies, including those which may be affected by the U.S. and other countries' political reactions to those actions, and - other regulatory and legal requirements and industry standards, and changes thereto.
As our international operations continue to expand, our failure to appropriately address foreign currency transactions or the currency exposures associated with assets and liabilities denominated in non-functional currencies could adversely affect our consolidated financial condition, results of operations and cash flows. In addition, developments affecting particular countries can adversely affect our ability to access cash or other assets held in such countries.
A significant portion of our operations is currently located in the APAC region, particularly in Malaysia. The concentration of our operations, workforce, assets and profitability in that region exposes us to adverse developments, economic, political or otherwise, in those countries.
Changes in policies or trade agreements by or changes in elected officials of the U.S. or other governments could negatively affect our operating results due to trade wars, changes in duties, tariffs or taxes, currency exchange rate fluctuations, higher costs of compliance, or limitations on currency or fund transfers, as well as government-imposed restrictions on producing certain products in, or shipping them to, specific countries. Our current facilities in Mexico operate under the Mexican Maquiladora ("IMMEX") program. This program provides for reduced tariffs and eased import regulations. We could be adversely affected by changes in the IMMEX program or our failure to comply with its requirements.
Additionally, continued uncertainty regarding commercial dealings, tariffs, export regulations and other trade protection measures between the U.S. and China, heightened by escalating geopolitical tensions, may affect our ability to do business in China, may impact the cost of our products originating in China and may impact the demand for our products manufactured in China in the event our customers reduce or eliminate their operations in China. These actions could also affect the cost and/or availability of materials or components that we procure from suppliers in China, as well as create disruptions, delays, shortages or increased costs within our global supply chain. Government-imposed restrictions on where we or our customers can produce certain types of products or source components or with whom we can conduct business, such as named companies or industries identified in the 2021 National Defense Authorization Act, outbound investment restrictions, and trade regulations limiting advanced semiconductors and chip-manufacturing equipment, could limit our ability to sell or manufacture products or services in China, or source components from certain companies or geographies. These factors can negatively affect our operating results and financial position, including reducing our revenues and profitability as a result of having to minimize engagements in China, requiring us to shift such production to other potentially higher-cost locations, or increasing the cost of sourcing components.
Further, the extent to which the conflict between Russia and Ukraine, conflict in the Middle East or the escalating tensions between China and Taiwan or China and the U.S. may impact our business or results of operations will depend on future developments, including the severity and duration of any conflicts, their impact on global supply chains and their impact on regional and global economic conditions including the ability of our customers or suppliers to do business in those or surrounding countries and the inflationary effects of such conflicts on our profitability. These tensions have resulted in, and may continue to cause, global disruptions creating significant volatility in financial markets and the global economy.
