Are investors really made whole with a make-whole call provision?

After Dan’s EFN analysis for East Coast Yachts (see the Mini Case in Chapter 3), Larissa has decided to expand the company’s operations. She has asked Dan to enlist an underwriter to help sell $50 million in new 20-year bonds to finance new construction. Dan has entered into discussions with Kim McKenzie, an underwriter from the firm of Crowe &
Mallard, about which bond features East Coast Yachts should consider and also what coupon rate the issue will likely have. Although Dan is aware of bond features, he is uncertain as to the costs and benefits of some of them, so he isn’t clear on how each feature would affect the coupon rate of the bond issue.
