Guys,
With data in the table on Exhibit 7 this is the terminal payoff I came up with from Cox's perspective. This is assuming that the investor to satisfy the obligation, buys the common stock at the end of 3 years with extra cash and chooses to retain the preferred stock as is, since it pays 7% coupon which is better than market rates for a BBB rated industrial bond (Exhibit 6). Notice the spread between the Call and Put (where the terminal payoff is a constant at 50$).
With this I think we can rewrite the Terminal payoff in terms of Call/Put/Stock as below.
From Parity Eqn: Bond - Put = Stock - Call
or
Bond - Put + Call = Stock
But I haven't figured out how to interpret this data and not sure if I'm in the right direction...
