The conversion ratio is established when the bond is issued, and is: par value divided by the conversion price. In this case, the conversion price is set at $40 per share, so the conversion ratio is $1,000 par / $40 conversion price = 25:1 (25 shares per bond). If the bond moves to a 10 point premium over par, its new price will be 110, or $1,100 per bond. For the common stock to be valued at parity to the bond, the price per share must be $1,100 / 25 shares per bond = $44 per share parity price.
