This is problem 12-8 on page 429 of your text: You must evaluate the purchase of a spectrometer for the R&D department. The base price is $140,000, and it would cost another $30,000 to modify the equpment for special use by the firm. The equipment falls into the MACRS 3-year class and would be sold after 3 years for $60,000. The applicable depreciation rates are 33%, 45%, 15%, and 7% as discussed in Appendix 12A. The equipment would require an $8,000 increase in net operating working capital (spare parts inventory). The project would have no effect on revenues, but it should save the firm $50,000 per year in before-tax labor costs. The firm's marginal federal-plus-state tax rate is 40%. The firm's WACC ("hurdle rate" or "required rate of return") is 12% Question 12 (1 point) Given the information in the problem: What is the project's Modified Internal Rate of Return (MIRR)? 12% 7.74% 6.03% 4.02%
