Desai Industries is analyzing an average-risk project, and the following data have been developed. Unit sales will be constant, but the sales price should increase with inflation. Fixed costs will also be constant, but variable costs should rise with inflation. The project should last for 3 years. Under the new tax law, the equipment used in the project is eligible for 100% bonus depreciation, so it will be fully depreciated at t = 0. At the end of the project's life, the equipment would have no salvage value. No change in net operating working capital (NOWC) would be required for the project. This is just one of many projects for the firm, so any losses on this project can be used to offset gains on other firm projects. What is the project's expected NPV? Do not round the intermediate calculations and round the final answer to the nearest whole number. WACC 10.0% Equpiment cost $200,000 Units sold 53,000 Average price per unit, Year 1 $26.00 Fixed op. costs (constant) $150,000 Variable op. cost/unit, Year 1 $20.40 Expected annual inflation rate 5.00% Tax rate 25.0% O a. $191,591 O b. $100,143 O c. $150,143 O d. $179,635 O e. $141,591 Your company, CSUS Inc., is considering a new project whose data are shown below. The required equipment has a 3-year tax life. Under the new law, the equipment used in the project is eligible for 100% bonus depreciation, so the equipment will be fully depreciated at t = 0. The equipment has no salvage value at the end of the project's life, and the project does not require any additional operating working capital. Revenues and operating costs are expected to be constant over the project's 10-year expected operating life. What is the project's Year 4 cash flow? Equipment cost $70,000 $36,700 Sales revenues, each year Operating costs $26,200 Tax rate 25.0% O a. $8,400 O b. $13,125 O c. $7,875 O d. $13,708 O e. $10,500
