8-7 Operating Leverage and Fluctuations in Operating Earnings Assume that Jason Kidwell (from Problem 8-6) is able to purchase Toys n Things Inc. for $2.2 million. Jason estimates that after initiating his changes in the companys operations (i.e., the salary savings plus outsourcing savings described in Problem 8-6), the firms cost of goods sold are 55% of firm revenues, and operating expenses are equal to a fixed component of $250,000 plus a variable cost component equal to 10% of revenues. Under these circumstances, estimate the firms net operating income for revenue levels of $1 million, $2 million, and $4 million. What is the percentage change in operating income if revenues go from $2 million to $4 million? What is the percentage change in operating income if revenues change from $2 million to $1 million? Assume now that Jason is able to modify the firms cost structure such that the fixed component of operating expenses declines to $50,000 per year but the variable cost rises to 30% of firm revenues. Answer Problem 8-7(a) under this revised cost structure. Which of the two cost structures generates the highest level of operating leverage? What should be the effect of the change in cost structure on the firms equity beta?
