Abstract: Corporations finance themselves by selling claims to the expected future cash flows generated by their assets. The two basic claims issued are debt claims in the form of bonds and equity claims in the form of common stocks. Between these two endpoints, there exists a continuum of securities that possess features of both bonds and stocks. Among the most prominent of these hybrid securities is convertible bonds. A convertible bond is a combination of an option-free bond and the option to convert the bond into a given number of shares of the issuer's common stock. Convertible bonds may also be callable or putable or both. Depending on the performance of the underlying company, a convertible bond may behave more like a common stock or more like an option-free bond.
