Academic Explanation

ADRs are issued in two basic versions: sponsored and unsponsored. The most popular version today is sponsored, and for these, the creation of the ADR is initiated and supported by the company. As of 2002 there were 1,450 ADRs, including 200 unsponsored ADRs.

ADRs have no voting rights because the investor does not actually hold the shares.

There are four kinds of sponsored ADRs:

- Level I ADRs trade on the pink sheets (OTC bulletin board), are exempt from the SEC reporting requirements, but cannot be used for raising capital, or be listed on organized stock exchanges in the United States. More than eight hundred ADRs, such as Roche, Nestlé, and Volkswagen belong to this category. 

- Level II ADRs are listed and trade on U.S. exchanges—NYSE, AMEX, Nasdaq—but cannot be used for raising new equity capital. Financial statements must be partially reconciled with generally accepted accounting principles (GAAP). 

- Level III ADRs can raise new capital from American investors and are listed on U.S. exchanges. These ADRs are just like domestic stocks and require full compliance with GAAP and SEC regulations. 

- Rule 144A ADRs: Under Rule 144A, a company can raise new capital but only from qualified institutional buyers […]without compliance with GAAP/SEC regulations.
