“…By eliminating the conversion opportunity, managers force the convertible security holders to accept a fixed claim that is equal to the call price, thereby preventing them from sharing in any residual claim that is gained when the market realizes the firm's true value. The empirical studies of such "early" calls (e.g.. Tang, Kadapakkam, and Singer [1994], Hingorani, Makhija, and Shastri [1994]; Cowan, Nayar, and Singh [1993]) find positive abnormal returns to common stock when the calls are announced, suggesting that such calls signal managers' private expectations of higher future cash flows. These studies are not directly comparable to ours, given that "early" calls, by definition, are not delayed and do not serve as negative signals regarding future profitability.…”
