Valuation Effects of Corporate Debt Offerings

This paper analyzes the effect of corporate debt offerings on stock prices. Straight debt offerings have non-positive price effects, while convertible debt offerings have significantly negative effects. Public utility mortgage (non-convertible) bond offerings have marginally negative effects, and the effect is significantly negative when the proceeds are used to finance the utility's investment program. Cross-sectional regressions reveal no relation between offer-induced price effects and offering size, rating, post-offer changes in abnormal earnings or debt-related tax shields. The evidence is inconsistent with theories predicting that the price effects of capital structure changes go in the direction of the leverage change
