The impact of rights issues of convertible debt in Australian markets

Abstract

Australian convertible debt issues are rights issues of non-callable securities and are issued in a market characterised by thin trading, significant institutional investor participation rates and a high number of resource firms. However, this study documents a significant negative announcement effect for rights issues of convertible debt, similar to international evidence. An analysis of the determinants of the announcement effect supports variants of the information asymmetry and agency cost hypotheses. The results do not support the convertible debt models of Kim [Kim, Y., 1990. Informative conversion ratios, a signalling approach. Journal of Financial and Quantitative Analysis 25, 229–243], Brennan and Kraus [Brennan, M., Kraus, A., 1987. Efficient financing under asymmetric information. Journal of Finance 42, 1225–1243], Green [Green, R.C., 1984. Investment incentives, debt and warrants. Journal of Financial Economics 13, 115–136] but some support is found for Stein's [Stein, J., 1992. Convertible bonds as backdoor equity financing. Journal of Financial Economics 32, 3–22], convertible debt model and Mayers [Mayers, D., 1998. Why firms issue convertible bonds: the matching of financial and real investment options. Journal of Financial Economics 47, 83–102], sequential financing model. However, support is found for Brous and Kini [Brous, P.A., Kini, O., 1994. The valuation effects of equity issues and the level of institutional ownership: evidence from analysts’ earnings forecasts. Financial Management 23, 33–46], equity issue based external monitoring model and Eckbo and Masulis [Eckbo, B., Masulis, R., 1992. Adverse selection and the rights offer paradox.
