fee is referred to as the flotation cost. The amount of fee depends on the size and type of offering. Flotation cost is generally less for debt and preferred issues, and most analysts ignore it while calculating the cost of capital. However, the flotation cost can be substantial for issue of common stock, and can go as high as 68%.
