Pfizer, one of the largest pharmaceutical companies in the United States, is considering what its debt capacity is.

The Treasury bond rate at the time of the analysis was 6.50% and AAA bonds trade at a spread of 0.30% over the Treasury rate.
a. Estimate the current cost of capital for Pfizer.
b. It is estimated that Pfizer will have a BBB rating if it moves to a 30% debt ratio and that BBB bond shave a spread of 2% over the Treasury rate. Estimate the cost of capital if Pfizer moves to its optimal.
c. Assuming a constant growth rate of 6% in the firm value, how much will firm value change if Pfizer moves its optimal? What will the effect be on the stock price?
d. Pfizer has considerable R&D expenses. Will this fact affect whether Pfizer takes on the additional debt?
