American Depositary Receipt (ADR)
ADRs lower the barrier to cross-border investing and, for overseas companies, open a route into US capital markets—which is why they are so widely used in global equity investing. Many well-known companies are listed in the US as ADRs, making it far easier to take part in the growth of businesses around the world, alongside tools such as US stocks and ETFs for a diversified portfolio.
This article covers what an ADR is, how one works, the different levels, the benefits and risks, how ADRs compare with ordinary shares and GDRs, and what to check before you invest.
- An ADR is a US-bank-issued certificate representing foreign shares, traded in US dollars on US markets.
- Four parties make an ADR work: the company, a local custodian, a US depositary bank, and you.
- ADRs come in Level 1 (OTC), Level 2 (exchange-listed), and Level 3 (can raise new capital).
- One ADR doesn't always equal one underlying share—check the ADR ratio before comparing prices.

1. What Is an American Depositary Receipt (ADR)?
An American Depositary Receipt (ADR) is a certificate issued by a US depositary bank that represents ordinary shares in a foreign company. It lets investors buy and sell shares in non-US businesses in US dollars, on US securities markets.
The main purpose of an ADR is to lower the barrier to cross-border investing for global investors, while helping overseas companies reach US capital markets. Many internationally known companies—TSMC, Alibaba, and Sony among them—trade in the US in ADR form.
Core Features of an ADR
| Feature | Description |
|---|---|
| Traded in US dollars | Bought and sold directly in USD on a US exchange or over the counter |
| Backed by foreign shares | One ADR represents a set number of the foreign company's ordinary shares |
| Issued by a depositary bank | A major US bank handles issuance and administration |
| Convenient access | No overseas brokerage account needed to invest in global companies |
| Dividend entitlement | Most ADRs carry dividend rights similar to the underlying shares |
What Is the ADR Ratio?
When investing in ADRs, pay attention to the ADR ratio—because one ADR does not necessarily equal one underlying share.
| Example ratio | What it means |
|---|---|
| 1 ADR = 1 share | One ADR corresponds to one underlying share |
| 1 ADR = 5 shares | One ADR corresponds to five underlying shares |
| 5 ADRs = 1 share | Five ADRs represent a single underlying share |
Only once you know the ratio can you compare the ADR price against the underlying share price properly.
2. How Does an ADR Work? Depositary Banks, Underlying Shares, and the ADR Ratio
An ADR works by holding the overseas company's shares with a custodian bank; a US depositary bank then issues ADRs against the shares it holds, and those ADRs trade on the US market.
The ADR Issuance Process
Issuing an ADR breaks down into four broad steps:
- ① The overseas company issues its shares: the foreign business first issues ordinary shares in its home market.
- ② A custodian bank holds the shares: those shares are held by a local custodian.
- ③ A US depositary bank issues ADRs: the depositary bank issues ADRs matching the shares held.
- ④ Investors trade on the US market: investors buy and sell the ADRs in US dollars on a US exchange or OTC.
The Main Parties Involved
| Party | Main role |
|---|---|
| Overseas company | Issues the underlying shares and provides company information |
| Custodian bank | Holds the underlying shares in the local market |
| US depositary bank | Issues ADRs and handles dividends, disclosure, and other administration |
| Investor | Buys and sells ADRs and holds the corresponding economic rights |
How Is an ADR Priced?
An ADR's market price is driven mainly by three things:
- The underlying share price: the ADR tracks the rises and falls of the share behind it.
- The ADR ratio: ratios differ by company, so check how many underlying shares one ADR represents.
- FX moves: because the underlying trades in local currency, exchange rate shifts also feed into the ADR's dollar price.
So even though an ADR trades in dollars, its price reflects both the underlying share's performance and currency moves. Watch for short-term discounts or premiums between an ADR and its underlying shares.
3. What Types of ADR Are There? Level 1, Level 2, and Level 3 Compared
Depending on where they list and the regulation involved, ADRs fall into three types: Level 1, Level 2, and Level 3. The biggest differences are whether they can list on a major US exchange, and whether they can raise capital publicly.
Level 1 ADR
Level 1 ADRs carry the lightest regulatory requirements and usually trade over the counter (OTC). They don't have to meet full US listing standards, which makes them a common first step for overseas companies entering the US market.
Level 2 ADR
Level 2 ADRs can list and trade on the New York Stock Exchange (NYSE) or Nasdaq (NASDAQ). The company must meet Securities and Exchange Commission (SEC) disclosure requirements, but cannot raise new capital this way.
Level 3 ADR
Level 3 ADRs are the most fully regulated type. They can list on major US exchanges and also issue new shares publicly to raise capital, which is why they suit large companies committing seriously to US capital markets.
Comparison: The Three ADR Levels
| Item | Level 1 | Level 2 | Level 3 |
|---|---|---|---|
| Market | OTC | NYSE/NASDAQ | NYSE/NASDAQ |
| SEC regulation | Lighter | Stricter | Fullest |
| Can raise capital | × | × | ○ |
| Disclosure | Basic requirements | Full disclosure | Full disclosure |
| Suits | First step into the US market | Raising international visibility | Committing to US capital markets |
4. What Are the Benefits and Risks of Investing in ADRs?
ADRs make it easier to take part in opportunities at overseas companies, but like any financial product they carry both advantages and risks. Knowing them helps you judge whether ADRs fit what you're trying to do.
Benefit 1: A Lower Barrier to Overseas Investing
Investing in ADRs doesn't require opening a brokerage account in the company's home country. You buy and sell overseas equities through the US market, which removes much of the practical friction of cross-border investing.
Benefit 2: Trading in US Dollars
ADRs are priced and traded in US dollars, so you don't need to deal in the local currency. The process closely resembles trading ordinary US stocks, which also makes the portfolio easier to manage.
Benefit 3: Broader Global Allocation
Through ADRs you can invest in listed companies from Asia, Europe, and other markets—useful for spreading exposure across regions and adding diversity to a portfolio.
Risk 1: Currency Moves Affect the Price
Although ADRs trade in dollars, what sits behind them is a foreign company's shares. Moves in the underlying market's currency can therefore still affect how an ADR performs.
Risk 2: Liquidity, Discounts, and Premiums
Some ADRs trade on low volume, which can widen the bid-ask spread. An ADR's market price can also sit at a discount or premium to the converted price of the underlying, so the two don't always line up exactly.
5. ADRs vs Ordinary Shares vs GDRs: What's the Difference?
ADRs, ordinary shares, and Global Depositary Receipts (GDRs) all let you take part in a company's growth, but they differ in where they trade, how they're issued, and who they're for.
Comparison: ADRs, Ordinary Shares, and GDRs
| Item | ADR | Ordinary shares | GDR |
|---|---|---|---|
| Issued by | A US depositary bank | The company directly | An international depositary bank |
| Market | US exchanges/OTC | The company's home exchange | European or international markets |
| Currency | US dollars | Local currency | Mostly USD or EUR |
| Suits | Investing in overseas firms via the US market | Investing in the home market | International institutions and global investors |
If you want to hold the company's shares directly, ordinary shares fit better. If you want to reach overseas companies through the US market, an ADR is usually more convenient. GDRs are mostly used when a company raises capital or trades across several international markets.
6. What to Check Before Investing in ADRs: Fees, Tax, FX, and CFDs
Once you understand how ADRs work, a few checks before you actually invest will help keep costs down and avoid misreadings caused by differences between systems.
Confirm the ADR Ratio
Ratios differ from company to company—1:1, 1:2, and 1:5 are all common. Check the ratio before comparing an ADR's price with the underlying, so you don't misjudge whether a share looks cheap or expensive.
Watch Depositary Fees and Dividend Tax
Some ADRs carry a depositary service fee (ADR fee), usually charged by the depositary bank. Dividends may also have withholding tax deducted under the rules of the company's country of registration, so what you actually receive can differ from what you expected.
Check Volume and Liquidity
ADRs with lower volume tend to have wider bid-ask spreads, which can raise your trading costs. If you're starting out, it's worth focusing on the more actively traded ADRs first.
Also Worth Knowing: CFDs as an Alternative
If you care more about short-term price moves than holding the ADR itself, you can also take part in the price action of some overseas companies through a contract for difference (CFD).
CFDs don't require holding the actual certificate or shares and are more flexible to trade, but they carry leverage and margin risk—which makes them better suited as a supporting tool for experienced investors.
7. ADR FAQ
Q1. Can an ADR be converted into the underlying shares?
Yes, though whether you can depends on the terms of the issue and your broker's services.
Conversion is generally handled through the depositary bank, but it usually involves conversion fees, paperwork, and processing time—which is why most ordinary investors rarely convert between ADRs and underlying shares.
Q2. Why is an ADR's price sometimes different from the underlying share?
An ADR's price generally references the underlying share price, the ADR ratio, and FX—but US market supply and demand, different trading hours, and market sentiment can still produce a discount or premium.
When the gap gets too wide, arbitrage usually pulls the two prices back toward a more reasonable range.
Q3. Which companies issue ADRs?
Many overseas companies looking to expand into US capital markets may issue ADRs.
Large listed companies across Asia, Europe, and Latin America, for example, may list via ADRs on the New York Stock Exchange (NYSE), Nasdaq (NASDAQ), or over the counter (OTC), making it easier for global investors to trade them.
Q4. Are ADRs suitable for long-term investing?
If the company's fundamentals are sound, an ADR can serve as a long-term holding.
That said, keep an eye on currency moves, liquidity, and depositary fees, and plan your allocation around your own goals and risk tolerance.
Q5. Do ADRs always pay dividends?
Not necessarily.
Whether a dividend is paid depends on the issuing company's dividend policy. If the company pays a cash dividend, ADR holders usually receive the corresponding amount—though depositary service fees and applicable taxes may be deducted from it.
Q6. Besides ADRs, how else can I invest in overseas companies?
Alongside investing in ADRs directly, you can buy ordinary shares in overseas markets, invest in relevant ETFs, or use products such as US stock CFDs.
Each differs in how it trades and in cost, leverage, and risk profile, so choose the route that matches what you need.
8. Conclusion
American Depositary Receipts let investors reach opportunities at overseas companies through the US market, and they are a common cross-border tool in global capital markets. Understanding how ADRs work, the levels, the benefits and risks, and how they differ from ordinary shares and GDRs all lead to better-informed decisions.
Before investing in ADRs, check the ratio, depositary fees, tax treatment, and liquidity—then pick the route that fits your goals and risk tolerance, and build a more complete global allocation from there.
