[This study examines the testable implications of two hypotheses for why firms undertook debt-equity swaps over the period August 1981-June 1984. The first hypothesis is that firms used the accounting-based reported earnings gain from the swap to smooth an unexpected and transitory decrease in their earnings per share. The second hypothesis is that a swap enabled the firm to relax potentially binding sinking-fund constraints in the cheapest feasible manner. Empirically, this study concludes that firms undertook debt-equity swaps for both reasons, but that swapping to smooth earnings was a much stronger motivation than swapping to relax potentially binding sinking-fund constraints.]
