Assume that Mendoza is exploring whether to enter a complementary line of business. The existing business line generates annual cash revenues of approximately $5,600,000 and cash expenses of $3,780,000, one-third of which are labor costs. The current level of Investment in this existing division is $12,300,000. (Sales and costs of this division are not affected by the investment decision regarding the complementary line.) Mendoza estimates that incremental (noncash) net working capital of 542.000 will be needed to support the new business line. No additional facilities-level costs would be needed to support the new line--there is currently sufficient excess capacity. However, the new line would require additional cash expenses (overhead costs) of $460,000 per year. Raw materials costs associated with the new line are expected to be $1,500,000 per year, while the total labor cost is expected to double. The CFO of the company estimates that new machinery costing $4,000,000 would need to be purchased. This machinery has a five year useful life and an estimated salvage (terminal) value of $640,000. For tax purposes, assume that the Mendoza Company would use the straight-line method (with estimated salvage value considered in the calculation), Assume, further, that the weighted-average cost of capital (WACC) for Mendoza is 11% (after-tax) and that the combined (federal and state) income tax rate is 42%. Finally, assume that the new business line is expected to generate annual cash revenue of $4 200.000
