For cash flow in 11.2. vou should do vour work in Excel or an equivalent spreadsheet. 1. Park 11.2 The Wellington Construction Company is considering acquiring a new earthmover. The mover's basic price is $90,000, and it will cost another $18,000 to modify it for special use by the company. This earthmover falls into the MACRS five-year class. It will be sold after four years for $30,000. The purchase of the earthmover will have no effect on revenues, but it is expected to save the firm $35,000 per year in before-tax operating costs, mainly labor. The firm's marginal tax rate (federal plus state) is 25%, and its MARR is 10%. a. Is this project acceptable, based on the most likely estimates given? b. Suppose that the project will require an increase in net working capital (spare- parts inventory) of $5,000, which will be recovered at the end of year 4. Taking this new requirement into account, would the project still be acceptable? If the firm's MARR is increased to 18% and with the working capital requirement from (b) not in effect, what would be the required savings in labor so that the project remains profitable?
