Direct Answer
An ADR (American Depositary Receipt) is a US-listed, dollar-denominated certificate issued by a US depositary bank representing a stated number of a foreign company's ordinary shares held in custody abroad. It trades and settles on a US exchange like any domestic stock, while the foreign ordinary share itself trades directly on its home exchange, in the local currency, and requires a foreign-capable brokerage account to buy.
Key Takeaways
- An ADR represents a fixed number of underlying foreign ordinary shares - the ADR ratio - set by the depositary bank when the program is created.
- ADRs trade in US dollars on a US exchange or OTC market and settle like a normal US stock, with no foreign brokerage account required.
- Depositary banks convert foreign-currency dividends to US dollars for ADR holders, typically deducting a small conversion or custody fee.
- Sponsored ADRs involve the foreign company directly, carry SEC-level disclosure, and can list on NYSE or Nasdaq; unsponsored ADRs are bank-created, trade OTC, and carry lighter disclosure.
- Holding the foreign ordinary share directly can mean a tighter spread and no depositary fee, but requires direct FX conversion and foreign settlement and custody mechanics.
What Is an ADR?
An American Depositary Receipt is a negotiable US certificate representing ownership in a specified number of shares of a foreign company's stock. A US depositary bank holds the actual foreign ordinary shares in custody - usually through a custodian bank in the company's home market - and issues ADRs against them. The ADR itself is what trades on a US exchange or over-the-counter market, denominated in US dollars, while the underlying shares stay parked with the custodian abroad.
Because the ADR is a US security, it settles through the standard US clearing system (T+1, the same as an ordinary US stock), appears in a normal US brokerage account, and requires no foreign trading permissions. This is the main reason ADRs exist: they let US investors buy exposure to companies like a European luxury brand or an Asian semiconductor manufacturer without opening a foreign brokerage account or wiring money abroad.
What Does the ADR Ratio Mean?
The ADR ratio states how many underlying foreign ordinary shares one ADR represents. A 1:1 ratio means one ADR equals one ordinary share; other programs use ratios like 1:2, 1:4, or 1:20 - and in some cases a single ADR can represent a fraction of one ordinary share rather than a whole number of them. The depositary bank generally sets the ratio when the program launches, often to bring the ADR's US-dollar price into a range that's typical for a US-listed stock, and the ratio can be changed later through a ratio adjustment (economically similar to a stock split or reverse split).
Because the ratio varies by company and isn't a fixed rule, always confirm the current ratio for a specific ADR (from the depositary bank's program page or the company's investor relations site) rather than assuming any particular number - it directly affects how the ADR's price and dividend per share compare to the ordinary share's price and dividend on its home exchange.
How ADRs Trade, Settle, and Pay Dividends
ADRs trade during US market hours, in US dollars, through a normal US brokerage account - the same order types, the same commission structure, and the same settlement cycle as any other US-listed stock. No currency conversion happens at the point of purchase because the ADR itself is already dollar-denominated.
Dividends work differently under the hood. The foreign company pays its dividend in the local currency to the depositary bank, which converts the amount to US dollars at the prevailing exchange rate and distributes it to ADR holders - typically deducting a small conversion fee and, for sponsored programs, sometimes an annual custody or program fee disclosed in the depositary agreement. An investor holding the ordinary share directly instead receives the dividend in local currency and has to arrange their own conversion, which can be cheaper or more expensive depending on the investor's own banking or brokerage FX rates.
| Feature | ADR (US-listed) | Foreign ordinary share |
|---|---|---|
| Trading venue | US exchange or OTC market | Home-country exchange |
| Currency | US dollars | Local currency |
| Brokerage needed | Standard US brokerage account | Foreign-capable brokerage account |
| Dividend currency | US dollars (converted by depositary bank, fee applies) | Local currency (investor converts) |
| FX exposure | Indirect, via the underlying share's dollar value | Direct, at each conversion |
| Typical fees | Depositary conversion/custody fee | None from a depositary, but broker FX spread applies |
Sponsored vs. Unsponsored ADRs
This distinction matters for due diligence because it changes how much disclosure and oversight sits behind the certificate an investor is buying.
Sponsored ADRs
A sponsored ADR is created with the foreign company's direct involvement. The company signs a deposit agreement with a single depositary bank, and depending on the level (Level II or Level III), typically registers with the SEC and files periodic reports - often a Form 20-F annual report, which can differ in format from a domestic 10-K but still requires audited financials. Level II and Level III sponsored ADRs can list on a major exchange such as the NYSE or Nasdaq, subject to that exchange's listing standards. Sponsored programs generally offer investors more shareholder communication (annual reports, proxy materials) and a more liquid, exchange-traded market.
Unsponsored ADRs
An unsponsored ADR is created unilaterally by a depositary bank - sometimes more than one bank creates a separate unsponsored program for the same company - without a formal agreement with the foreign issuer. Unsponsored ADRs typically trade only over-the-counter, not on a major exchange, and carry lighter disclosure since the underlying company isn't directly involved in US reporting. That doesn't automatically make an unsponsored ADR unsafe, but it does mean the standard due-diligence checklist - confirming SEC filing status, exchange venue, and the depositary's own program disclosures - deserves an extra look before relying on it as a primary long-term holding.
| Item | Sponsored ADR | Unsponsored ADR |
|---|---|---|
| Company involvement | Direct - deposit agreement with one bank | None - created unilaterally by a bank |
| SEC filings | Typically yes (Level II/III) | Often exempt or minimal |
| Listing venue | Can list on NYSE/Nasdaq (Level II/III) | Usually OTC only |
| Disclosure level | Higher, comparable to other US-listed issuers | Lighter, worth extra verification |
Why Hold the Foreign Ordinary Share Instead?
An ADR isn't automatically the better choice - it's a convenience trade-off. An investor might prefer the foreign ordinary share directly for a few concrete reasons:
- Potentially tighter bid-ask spreads on the home exchange, where the stock is typically more heavily traded than the ADR itself.
- No depositary fee - the small per-share or annual charge the depositary bank deducts from ADR dividends and, in some programs, periodically from the ADR balance.
- Full access to shareholder mechanics in the home market, such as voting or corporate-action participation that can be more limited or administratively slower to reach ADR holders.
The cost of that choice is real: it requires a brokerage that offers direct foreign-market access (many mainstream US brokerages don't, for most retail accounts), and it exposes the investor directly to FX conversion on every trade and dividend, plus foreign settlement timelines and custody arrangements that the ADR structure otherwise handles behind the scenes. For a sponsored, SEC-registered ADR trading on a major exchange, the practical difference for a typical buy-and-hold investor is often small; the direct-ownership route matters more for active traders sensitive to spread cost or investors who specifically want full home-market shareholder rights.
Common Mistakes and How to Avoid Them
| Mistake | Why it causes problems | Better practice |
|---|---|---|
| Assuming a 1:1 ADR ratio | Comparing the ADR price directly to a headline ordinary-share price without adjusting for the ratio produces a meaningless comparison. | Confirm the specific ADR's ratio before comparing per-share price, dividend, or valuation metrics. |
| Treating all ADRs as equally disclosed | An unsponsored, OTC-traded ADR carries meaningfully lighter disclosure than a sponsored, exchange-listed one. | Check sponsorship status and SEC filing history before relying on an ADR as a core long-term holding. |
| Ignoring the depositary fee | A small recurring fee can quietly reduce realized dividend income over many years if never accounted for. | Read the deposit agreement's fee schedule, typically disclosed in the ADR's SEC filings or the depositary bank's program page. |
| Forgetting FX still matters | Because the ADR is dollar-denominated, investors can mistakenly think they've avoided currency risk entirely. | Recognize that the ADR's dollar value still moves with the underlying share's local-currency price and the exchange rate together. |
Risks and Limitations
Currency exposure doesn't disappear. Because an ADR's US-dollar price reflects the underlying ordinary share's local-currency price translated at the current exchange rate, ADR holders carry the same underlying FX exposure as a direct shareholder - the dollar-denomination only changes what currency the exposure is expressed in, not whether it exists.
Depositary and program risk. Fee schedules, ratio adjustments, and even ADR program terminations are set by the depositary bank and, for sponsored programs, the deposit agreement - terms that can change and that most investors never read in full before buying.
Unsponsored-program disclosure gaps. Lighter SEC oversight on unsponsored ADRs means an investor may have less timely or complete information than they would for a domestically listed company or a sponsored, exchange-listed ADR.

Frequently Asked Questions
What is the difference between a sponsored and an unsponsored ADR?
A sponsored ADR is created with the foreign company's direct involvement - the company works with a single depositary bank, typically files with the SEC, and the ADR can list on a major exchange like the NYSE or Nasdaq. An unsponsored ADR is created by a depositary bank on its own initiative, without a formal agreement with the foreign company, usually trades only over-the-counter, and carries lighter disclosure than a sponsored, exchange-listed ADR.
Do ADRs pay dividends in US dollars?
Yes. The depositary bank collects the dividend in the foreign currency, converts it to US dollars, and pays ADR holders in dollars - typically deducting a small conversion or custody fee before distribution. An investor holding the foreign ordinary share directly instead receives the dividend in the local currency and must convert it themselves.
What does the ADR ratio mean?
The ADR ratio states how many underlying foreign ordinary shares a single ADR represents - it might be 1-to-1, or a ratio like 1-to-2 or 1-to-20, depending on how the depositary bank sized the certificate relative to the foreign share's price. The ratio is set when the ADR program is created and generally does not change, though it can be adjusted later.
Can I buy foreign ordinary shares through a US brokerage?
Only if the brokerage offers direct access to the relevant foreign exchange, which many mainstream US brokerages do not for most retail accounts. Where that access exists, buying the ordinary share directly avoids ADR-related fees but exposes the investor to direct currency conversion, foreign settlement timelines, and custody arrangements that a US-listed ADR handles on the investor's behalf.
Why would an investor choose an ordinary share over an ADR?
Reasons include a potentially tighter bid-ask spread on the home exchange, avoiding the depositary bank's periodic fee, and access to the full float and voting mechanics of the local market. The tradeoff is needing a foreign-capable brokerage account and taking on direct FX conversion and foreign settlement and custody mechanics that the ADR structure otherwise absorbs.
