You are the sole bondholder in a firm that will be liquidated at its market value next year. For example, if the market value of the firm ends up being $70M next year, then the firm will be sold (liquidated) for $70M. Your main concern is that you will not be paid back the $50M you are owed next year, as the market value of the firm next year could end up being less than the $50M that you are owed. 

a) Provide the payoff diagram for the bondholder with the market value of the firm on the x-axis. The financial manager of the firm is deciding whether he should take on one last risky project before the firm is liquidated next year. If this project is accepted, then the potential liquidation value of the firm could be much higher next year, but it could also be much lower. If the manager does not take on the risky project, we will assume that the manager does nothing instead. 

b) Suppose that the financial manager decides to do nothing. In this case, the market value of the firm will equal either $60M (state A) or $40M (state B) next year, with equal probability. It follows that upon liquidation next year, the bondholder with either receive the $50M they are owed (state A) or only $40M (state B). In each state, the stockholder receives whatever is left over after the bondholder is paid off. What is the expected liquidation value of the firm? 

What is the expected payoff to the bondholder? What is the expected payoff to the stockholder?
