Industry conditions, growth opportunities and market reactions to convertible debt financing decisions

Firms that issue convertible debt have high debt- and equity-related costs of external finance. Existing theories of convertible debt finance differ primarily in their identification of the specific causes of the debt- and equity-related costs of external finance. To assess the theoretical issuance motives separately, we propose a simple framework that characterizes how issuers should design convertible debt to efficiently mitigate specific debt- and equityrelated costs of external finance. We provide evidence from 588 security offer announcements that supports the hypotheses that: (1) convertible debt can be designed to mitigate different combinations of debt- and equity-related costs of external finance and (2) share price reactions depend on the security design decisions. The results also illustrate that the relations between firm value, financial leverage, investment opportunities, and the rate of future growth are more complex among convertible debt issuers than situations where firms issue standard financial securities.
