“…Frequent attention has been paid in the finance literature to the valuation gain that can be realized for shareholders when a firm calls, for retirement and refunding, an existing nonconvertible debt issue (Bowlin, 1966;Boyce and Kalotay, 1979a;Brick and Wallingford, 1985;Emery and Lewellen, 1984;Finnerty, 1986;Lewellen and Emery, 1981;Livingston, 1980;Ofer and Taggart, 1977;Pye, 1966;Yawitz and Anderson, 1977).
