Sponsored vs. unsponsored ADRs: who set it up, and why it matters

Every ADR has a depositary bank behind it. The question is whether the foreign company asked for it. A sponsored ADR exists because the company signed a contract with one depositary. An unsponsored ADR exists because a depositary decided there was enough U.S. demand to open one on its own. The difference rarely shows up in a stock quote, but it can show up in your fees, your dividends, and how much you can learn about what you own.

Sponsored ADRs

In a sponsored program, the foreign company enters into a deposit agreement with a single depositary bank. That agreement spells out who pays for what, how dividends are distributed, how votes are passed through, and what happens if the program ends. The SEC describes the depositary in a sponsored program as handling recordkeeping, shareholder communications, and dividend payments under its agreement with the company.

Sponsored programs come in levels. The lowest trades over the counter; the higher levels list on the NYSE or Nasdaq and require the company to file annual reports with the SEC. Every exchange-listed ADR is sponsored. Details are in ADR levels explained.

Because the company is a party, it has a say in the fee schedule and usually supports the program with English-language reports, investor relations contacts, and proxy materials that reach ADR holders.

Unsponsored ADRs

An unsponsored ADR is created by a depositary bank without a deposit agreement with the company. The SEC notes these are often established in response to U.S. market interest rather than at the company's request. They trade only over the counter.

The legal opening for unsponsored programs is the SEC's Rule 12g3-2(b) exemption, which lets a foreign company avoid SEC registration if its shares are primarily traded on a foreign exchange and it publishes its key home-market documents in English online. In 2008 the SEC made that exemption automatic, with no application needed. To open an unsponsored program, the depositary files a registration statement on Form F-6 stating that it reasonably believes the company qualifies. Global Finance reported that more than 1,000 unsponsored programs were created in the three months after the amended rule took effect in October 2008.

Unsponsored programs remain an active channel. In June 2025, BNY announced an unsponsored ADR on a Canadian supermarket chain, which it described as the first ADR on a Canadian equity. Canadian investors have historically just bought the shares directly; see buying Canadian stocks from the U.S.

Why one company can have several unsponsored ADRs

A sponsored program has one depositary by contract. Unsponsored programs have no such exclusivity, so competing banks can each open their own on the same company's shares. You might see two or three OTC tickers for the same European company, each run by a different depositary.

They are not interchangeable. Each one has:

• its own ratio of ADRs to ordinary shares,
• its own fee schedule, set by that depositary alone,
• its own exchange-rate practice when converting dividends, and
• its own liquidity, which may be thin.

As a result, two unsponsored ADRs on the same company can pay slightly different dollar dividends for the same underlying payout. When a company later decides to set up a sponsored program, existing unsponsored programs are typically terminated or folded into it. That transition is covered in ADR terminations and delistings.

Fee and information differences

Fees on both types are charged per ADR, usually netted from dividends. The amounts vary by program, so the only reliable figure is the one in that ADR's own documents. See ADR fees for how to find it.

On information: a sponsored Level II or III company files an annual report on Form 20-F with the SEC, available on EDGAR. An unsponsored ADR's company files nothing with the SEC; you rely on its English-language disclosures in the home market, which may follow different accounting rules. Our guide to reading foreign financial statements helps there.

How to tell which one you hold

1. Check where it trades. If it is on the NYSE or Nasdaq, it is sponsored. If it is OTC, it could be either.
2. Look at the company's investor relations site. Companies with sponsored programs usually have an "ADR" page naming the depositary, ticker, CUSIP, and ratio. If the page names a different bank than the one behind your ticker, yours is likely unsponsored.
3. Find the Form F-6 on EDGAR. Every ADR is registered on Form F-6. Search EDGAR for the company name and look for F-6 filings. Unsponsored filings are sometimes filed under a name that includes "unsponsored ADR facility" and list only the depositary as the filer, with no company signature.
4. Check the depositary's directory. BNY, Citi, JPMorgan (adr.com), and Deutsche Bank each publish program listings that typically state whether a program is sponsored, its level, and its ratio.
5. Ask your broker. The ADR's CUSIP pins down exactly which program you own.

Does it matter for you?

For a long-term holder collecting dividends, the main practical differences are information quality, fee control, and what happens if the program is shut down. None of that makes an unsponsored ADR unusable, but it does mean doing a little more homework. If the company also has a sponsored program or a liquid home-market listing, compare your options using our guide to ADRs vs. foreign ordinary shares.
