Vermont Automotive is a regional chain of auto parts stores. The managers of the individual stores are evaluated using ROI. Vermont requires managers to earn an ROI of at least 10 percent of assets. The manager of the Erie store estimates revenues in the following year will be $3,750,000, cost of goods sold will be $2,180,000, and operating expenses for this level of sales will be $310,000. Investment in the store assets throughout the year is $3,500,000 before considering any changes. A representative of Hoffman Audio approached the manager about carrying Hoffman's line of car audio systems. This line is expected to generate $1,000,000 in sales in the coming year at the Erie store with a merchandise cost of $780,000. Annual operating expenses for this additional merchandise line total $120,000. To carry the line of goods, an inventory investment of $750,000 throughout the year is required. Hoffman is willing to "floor-plan" the merchandise so that the Erie store will not have to invest in any inventory. The cost of floor planning would be $65,000 per year. Vermont's marginal cost of capital is 7 percent. Ignore taxes. Required: a. What is the Erie store's expected ROI for the coming year if it does not carry Hoffman's merchandise? b.
