Situation
Proposition I.
rsL = rsU + (rsU-rd)x (D/S)
WACC =
wd*rd + wce*rs = (D/V)*rd + (S/V)*rs
WACC = 2.24% + 11.8%
Chapter 21. Mini Case
David Lyons, the CEO of Lyons Solar Technologies, is concerned about his firm's level of debt financing. The company uses short-
term debt to finance its temporary working capital needs, but it does not use any permanent (long-term) debt. Other solar
technology companies average about 30 percent debt, and Mr. Lyons wonders why the difference occurs, and what its effects are
on stock prices. To gain some insights into the matter, he poses the following questions to you, his recently hired assistant.
a. Business Week recently ran an article on companies' debt policies, and the names Modigliani and Miller (MM) were mentioned
several times as leading researchers on the theory of capital structure. Briefly, who are MM, and what assumptions are embedded
MM assumptions hold, and then:
a. Find V, S, rsL, and WACC for Firms U and L.

1. The gain from the tax shield will be lower using the compressed APV model than under MM because the
CAPV model discounts the interest tax shield at the unlevered cost of equity, which is larger than the cost of
debt. The MM model discounts the tax shield at the cost of debt.
3. The value of the firm, whether levered or not, will be larger with growth, provided ROIC is greater than
WACC. Although we don't show it here, ROIC is greater than WACC, so the value of the firm increases with

e. Suppose the expected free cash flow for Year 1 is $250,000 but it is expected to grow faster than 7% during
the next 3 years: FCF2 = $290,000 and FCF3 = $320,000, after which it will grow at a constant rate of 7%. The
expected interest expense at Year 1 is $80,000, but it is expected to grow over the next couple of years
before the capital structure becomes constant: Interest expense at Year 2 will be $95,000, at Year 3 it will be
$120,000 and it will grow at 7% thereafter. What is the estimated horizon unlevered value of operations (i.e.,
