ADRs vs Ordinary Shares Explained: Depositary Receipts, Fees and FX
An American Depositary Receipt (ADR) is a US-traded security representing an ownership interest in shares of a non-US company held through a depositary arrangement. An ADR may represent one underlying ordinary share, multiple shares or a fraction of one share. Its dollar price is linked to the home-market share price through the depositary ratio and foreign exchange, but fees, liquidity and trading schedules can create differences.
For global stock researchers, an ADR and its home-market ordinary share are related but not always interchangeable in practice. The structure affects custody fees, conversion, voting, settlement and reporting. This guide explains the depositary chain and numerical price relationship without assuming that a currency conversion or apparent price gap is a free arbitrage opportunity.
Key takeaways
- ADRs represent an interest in deposited underlying foreign shares through a US depositary bank.
- The ADR-to-ordinary-share ratio must be checked before comparing prices or market capitalisation.
- Depositary arrangements can charge custody, conversion and other fees.
- Trading currency in US dollars does not remove economic exposure to the company or foreign exchange.
- Sponsored and unsponsored ADR programmes differ in issuer involvement and disclosure arrangements.
What is an ADR and how is it created?
ADR stands for American Depositary Receipt, a negotiable security associated with American Depositary Shares (ADSs). SEC Investor.gov describes ADRs as representing interests in shares of non-US companies held through a US depositary bank, often through a local custodian. The ADR typically trades and settles through US market infrastructure, letting investors access foreign company exposure without directly placing an order on the company’s home exchange.
An ADR is not a new operating company or a separate business. It represents a contractual chain of interests connected to underlying shares. Depositary arrangements may specify how dividends are received and converted, whether and how voting instructions are collected, how corporate actions are handled and under what conditions investors can cancel ADRs in exchange for underlying local shares. These details belong in the deposit agreement.
ADR versus ADS: what the terms mean
American Depositary Shares are the interests in underlying deposited securities. Receipts evidence those interests; in market conversation, ADR and ADS are often used loosely or interchangeably. The depositary ratio is central: one ADR may represent one ordinary share, several ordinary shares or a fraction of one. Ratios can change due to corporate actions or depositary programme adjustments, so historic price series and current ratios may require reconciliation.
Do not compare a $100 ADR and a £20 ordinary share without considering both ratio and exchange rate. The higher ADR price may simply represent multiple underlying shares rather than an expensive claim on the same business. A correct economic comparison begins by converting the ordinary share quotation into USD and multiplying by the number of underlying shares represented by each ADR.
Worked example: converting a foreign share price
Assume a fictional UK company’s ordinary shares trade at £20 per share, and a US ADR represents two underlying ordinary shares. Suppose the exchange rate is £1 = $1.25. A simplified parity value per ADR is £20 × 2 × 1.25 = $50. The calculation ignores fees, market spread, time differences and any depositary programme restrictions.
If the UK shares rise to £22 while the dollar strengthens so that £1 = $1.15, the theoretical ADR parity becomes £22 × 2 × 1.15 = $50.60. Thus a 10% increase in the sterling share price translates into only a 1.2% rise in the illustrative dollar ADR parity because currency translation moved against it. A USD-traded security does not eliminate the economic effect of GBP/USD.
Sponsored versus unsponsored ADR arrangements
In a sponsored ADR programme, the foreign issuer enters into a deposit agreement with the depositary, with programme governance and disclosure determined by the relevant level and applicable regulations. Unsponsored programmes may be established by depositaries without the foreign company’s direct agreement. The distinction can affect issuer involvement, communications and the investor experience.
Not all ADR programmes have the same reporting and listing obligations. SEC investor education describes different programme levels, including exchange-listed arrangements and over-the-counter trading in other cases. Investors should identify the exact programme, listing venue, depositary and filings rather than assume that every foreign issuer has identical US disclosure requirements or investor protections.
Why depositary fees are important
Depositary banks may charge service or custody fees to ADR holders. SEC Investor.gov notes that these fees are often deducted from dividends distributed through the depositary chain but may also be collected through brokers when a programme does not pay periodic dividends. Other possible charges relate to conversion, issuance, cancellation, currency exchange and voting services.
The charges depend on the deposit agreement, so do not apply a single universal per-ADR fee. Review the fee schedule in the relevant Form F-6 registration statement and ask the broker how costs are passed through. When assessing expected dividend yield, account for foreign withholding, depositary fees, exchange conversion, brokerage charges and local tax treatment where relevant.
ADR prices and the timing of international markets
Home-market shares and US ADRs may trade during partly different market hours. A London exchange share can close before US trading ends. New information after the home close may cause the ADR to move even though the underlying ordinary share quotation appears unchanged on the last available home-market print. When the home market reopens, local prices may adjust to the new information.
This timing issue helps explain why a naive spreadsheet can show an apparent ADR premium or discount that is not immediately tradeable. Exchange rates may also change between market closes. True cross-market arbitrage requires access to both securities, the ability to create or cancel depositary receipts, available borrow, settlement arrangements and sufficient liquidity after fees.
Liquidity, spreads and conversion constraints
The local ordinary share and ADR can have very different trading volume and bid–ask spreads. One market may be more liquid for institutional blocks, while the other is more convenient for a particular investor. The cost of converting ADRs to underlying stock may be significant, and legal or operational restrictions can prevent quick conversions. Some programmes can be terminated or changed, triggering fees or other consequences.
Large differences in observed prices should be analysed in the context of executable bid and offer quotations, not just stale last-trade data. Broker custody capabilities also matter. Not every retail platform permits depositary cancellation or local-market delivery, so an apparent parity advantage may not be accessible to the end investor.
Shareholder voting, dividends and corporate actions
ADR investors may have a mechanism to instruct the depositary how to vote underlying shares, but timing and procedures differ from directly owning ordinary shares. In some cases, voting rights may be restricted by programme terms, local law or practical deadlines. Dividends paid in a home-market currency may be converted and distributed after taxes and applicable depositary fees. Investors should check whether the chosen broker forwards notices promptly.
Stock splits, share consolidations, rights offers, tender offers or spin-offs can be handled through the depositary rather than through direct local share registration. The ADR ratio can also change. This creates an additional layer of operational and disclosure risk. Consult the programme documents when a corporate action is announced; do not infer entitlements solely from the underlying ordinary share press release.
Reporting obligations and foreign-issuer analysis
Some foreign issuers with listed ADRs file Form 20-F annual reports and other US disclosures; many also publish home-market regulatory announcements. Requirements vary by issuer status and programme. The presence of an ADR ticker should not be interpreted as a guarantee of identical US and domestic accounting standards, timeliness or governance protections.
Review the company’s financial statements, auditor information, currency denomination, ownership structure, country risk and legal recourse available to depositary holders. An ADR gives exposure to a company’s business risks plus the contractual depositary arrangement. The issuer’s operating revenue currencies may be different from both the ADR trading currency and its home listing currency.
A practical international-equity checklist
Identify the exact ADR and underlying ordinary share identifiers and depositary ratio. Convert home share prices using the same timestamp and a consistent FX quote. Compare executable spreads, volumes and custody charges. Read the deposit agreement for voting, cash distributions, termination and conversion rights. Review foreign tax withholding, corporate-action notices and the company’s most relevant financial reports.
Finally separate three questions: whether the underlying company is attractive, whether an ADR is an appropriate instrument for accessing it and whether your base-currency return is acceptable. A company can be well researched while the specific depositary line is expensive or illiquid. Conversely, a liquid ADR does not reduce the business risk of a poorly financed issuer.
Common misconceptions
A high ADR dollar price does not prove the foreign stock is more expensive. A dollar-traded ADR is not a guaranteed hedge against exchange-rate movements. ADRs may have fees and voting arrangements distinct from direct share ownership. Sponsored and unsponsored programmes are not identical. Comparing stale home-market quotes against live ADR quotes can create false arbitrage conclusions.

Frequently asked questions
Is an ADR the same as an ordinary share?
It represents an interest in ordinary shares through a depositary arrangement. The holder’s trading, custody and corporate-action experience can differ.
Can one ADR represent more than one foreign share?
Yes. Ratios can be greater than one, one-to-one or fractional; check the programme.
Does owning an ADR eliminate FX risk?
No. The ADR trades in dollars, but its value is linked to underlying shares and currency conversion.
Do ADR holders always have identical voting rights?
Not necessarily. The deposit agreement and applicable local law determine voting processes and limitations.
Why might an ADR seem cheaper than the local share?
Check ratio, FX timestamp, market hours, quotes, spreads and fees before interpreting the apparent gap.
