ADRs and Foreign Companies: What Are You Actually Buying?

US markets host a large number of foreign companies from around the world: TSMC, ASML, Toyota, Alibaba, and many more. When you buy these companies, what you often acquire is not their original shares listed on their home exchange but a type of certificate called an ADR. Understanding it is essential when investing in non-US companies on US markets.

What Is an ADR?

An ADR (American Depositary Receipt) is a certificate that lets a foreign company trade on a US exchange: a US depositary bank holds the foreign company's actual shares and then issues corresponding certificates (ADRs) that list in the US. The ADR you buy represents a set number of the underlying foreign shares. It lets you buy global companies in US dollars without opening an overseas account, which is very convenient, but what you hold is a certificate, with the depositary bank added as an intermediary layer.

Special Structures Behind Some ADRs (the VIE Example)

Not all ADRs are alike. Because of foreign-ownership restrictions in certain industries, some emerging-market companies adopt special structures such as the VIE (variable interest entity): the entity actually listed in the US is an offshore-registered shell company that controls the real operating entity onshore through a series of contracts, rather than owning it directly. This means investors hold economic interests under contractual control rather than direct equity in the operating entity. Such structures introduce additional uncertainty and are an unavoidable feature of some ADRs.

Several Types of Risk to Understand

• Structural risk: the legal enforceability of contractual-control structures such as VIEs is uncertain in extreme scenarios.
• Policy and regulatory risk: regulatory changes in both the company's home country and the US can materially affect the share price, and some sectors have historically been extremely volatile.
• Delisting/audit risk: disputes over cross-border audit oversight have at times put some foreign companies under delisting pressure, so watch compliance developments.
• Currency risk: the business is denominated in the local currency while the shares trade in US dollars, so exchange-rate swings affect your actual returns.

“Risk comes from not knowing what you are doing.”— Warren Buffett

Approach It Rationally, Not Fearfully

None of this is meant to steer you away from foreign companies or ADRs; the point is that before investing you should understand exactly what you are buying and where the risk comes from. This is the circle-of-competence principle in action: if you cannot make sense of an ADR's structure and its home country's policies, do not take a large position. Once you understand it, then decide whether it is worth it and how much to allocate.

How This Maps to Our Platform

When this platform values a business, structural and policy risk form part of the long-term assumptions and shape the required return and scenario judgments. For ADR names with unusual structures, pay particular attention to how the report flags risk and uncertainty, and combine that with your own understanding of the relevant policies to reach a rounded judgment.
