Exchangeable bond (or XB) is a type of hybrid security consisting of a straight bond and an embedded option to exchange the bond for the stock of a company other than the issuer (usually a subsidiary or company in which the issuer owns a stake) at some future date and under prescribed conditions. An exchangeable bond is different from a convertible bond. A convertible bond gives the holder the option to convert bond into shares of the issuer.

The pricing of an exchangeable bond is similar to that of convertible bond, splitting it in straight debt part and an embedded option part and valuing the two separately.

Price of exchangeable bond = price of straight bond + price of option to exchange
