convertible bond


A recent paper by Finnerty expresses the value of a convertible bond as the value of the straight bond component plus the value of the option to exchange the bond component for a specified number of conversion shares and develops a closed-form convertible bond valuation model. This article illustrates how to apply the model to value nonredeemable convertible bonds and callable convertible bonds. The article also compares model and market prices for a sample of 148 corporate convertible bonds issued between 2006 and 2010. The average median and mean pricing errors are -0.18% and 0.21%, respectively, which are within the average bid-ask spread for convertible bonds during the postcrisis sample period.
