Interest charges on debt are $8,000 per year; preferred dividends are $5,000; tax rate is 34%. (A) Compute the operating breakeven point in units. (B) Compute the degree of operating leverage (DOL). (C) Compute the degree of financial leverage (DFL). (D) Compute the degree of total leverage (DTL) using Formula (12.9) on p. 478. Verify your figure by comparing with the product, DOL x DFL. (How do the two results compare?) (E) In Part D above, what assumption is made with regard to EPS? (Hint: See footnote on p. 478.)
