Mandatory Convertible

A bond that must be converted into common stock in the company issuing it on or before a certain date. An advantage of a mandatory convertible to the investor is the fact that it guarantees a certain return up to the conversion date, after which there is no guaranteed return but the possibility of a much higher return. A publicly-traded company issues mandatory convertibles when it needs to raise the capital provided by issuing stock, but when doing so would put a strain on the price of existing shares.
