284 Chapter 12 Capital Structure
23. The degree of operating leverage is defined as the percentage change in operating earnings
associated with a given percentage change in sales.
24. Two firms, although they operate in different industries, have the same expected earnings per
share and the same standard deviation of expected EPS. Thus, the two firms must have the same
business risk.
25. A consistent supply of capital is essential for the long-run success of a firm. Although a firm may
have access to capital under all types of economic conditions, the concept of financial flexibility
implies that the firm can obtain capital on acceptable, competitive terms.
26. The benefit to the firm of the tax deductibility of interest can be lowered if the firm’s marginal tax
rate is reduced by accumulated depreciation or tax-loss carry-forwards.
27. An all equity firm has some risk inherent in its operations. When the firm decides to finance some
of its operations with debt, it exposes itself to financial risk and it increases its business risk.
28. Risk can be apportioned between financial and business risk. Financial risk and business risk are
related in that, as business risk increases so does financial risk, although the correlation between
the two is not perfect.
29. The fact that some managers are more aggressive in their use of debt financing in attempting to
boost profits does not influence the optimal or value-maximizing capital structure.
30. If we include the cost of bankruptcy in the MM analysis of capital structure in a world with taxes,
we would tend to believe that the cost of debt increases as leverage increases and that there is
probably an optimal capital structure.
31. As the percentage of debt in a firm’s capital structure increases, its financial risk increases. Once
the firm increases its debt beyond the optimal level, rising interest charges result in an immediate
decrease in EPS.
32. Firm A has a higher degree of business risk than Firm B. Firm A can offset this by using less
financial leverage. Therefore, the variability of both firms’ expected EBITs could actually be
identical.
33. Generally, as debt is substituted for equity, risk, as measured by the coefficient of variation of
EPS, increases. This negative effect works against the positive effect of substituting debt for
equity, which is that higher leverage increases expected EPS.
