Assume that MM’s theory holds except for taxes. There is no growth, and the $60 of debt is expected to be permanent. Assume a 33% corporate tax rate.

a.	How much of the firm’s value is accounted for by the debt-generated tax shield? (Round your answer to 2 decimal places.)

PV tax shield

b.	What is United Frypan’s after-tax WACC if rdebt = 6.7% and requity = 16.3%? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

c.

Now suppose that Congress passes a law that eliminates the deductibility of interest for tax purposes after a grace period of 5 years. What will be the new value of the firm, other things equal? Assume an 6.7% borrowing rate. (Do not round intermediate calculations. Round your answer to 2 decimal places.)

New value of the firm

Explanation:

Some values below may show as rounded for display purposes, though unrounded numbers should be used for the actual calculations.

a.

PV tax shield = 0.33 × debt = 0.33 × $60 = $19.80

b.

c.

Annual tax shield = 0.33 × interest expense = 0.33 × (0.067 × $60) = $1.33

PV tax shield = $1.33 × annuity factor (6.7%, 5 years)

                   

The total value of the firm falls by $19.80 − $5.48 = $14.32.

The total value of the firm = $205 − $14.32 = $190.68.
