After 4 years of use, a well logging tool manufacturer company has decided to replace capital equipment used on its formation repeat tester product line. The equipment was MACRS-depreciated over a 3-year recovery period. After-tax MARR is 12% per year, and Te is 30% in the United States. The cash flow data is tabulated in $1000 units (for example, 230 would mean $230,000). year Purchase, $ Gross income, $ Salvage, $ Operating expenses, S -1800 850 960 650 350 -120 -170 -220 -210 4 700 a) Utilize the CFBT series and AW value to determine whether the equipment investment exceeded the MARR Hint: Positive values of Annual Worth or Present Worth indicate justified projects. (3.25 Marks) 6) Calculate MACRS depreciation and estimate the CFAT series over 4 years. Neglect any tax impact caused by the $700.000 salvage received in year 4. (1.25 Marks) (c) Utilize the CFAT series and AW value to determine whether the investment exceeded the MARR. Hint: Positive values of Annual Worth or Present Worth indicate justified projects. (1.75 Mark) d) Determine the After-Tax ROR of the project by two different ways: First, by estimating the Before-Tax ROR and calculation of the After-Tax ROR from the value of Before-Tax ROR. Second, by estimating the After-Tax ROR directly from CFAT data. Which value is higher? Note: You can consider linear interpolation between 5% and 30%. Write down the interpolation steps. (4 Marks)
