The following information applies to the next four questions. You have been asked by the president of the Farr Construction Company to evaluate the proposed acquisition of a new earth mover. The mover's basic price is $50,000, and it would cost another $10,000 to modify it for special use. Assume that the mover falls into the MACRS three-year class (allowance percentages 33%, 45%, 15%, 7%), would be sold after 3 years for $20,000 and would require an increase in net working capital (spare parts inventory) of $2,000. The earth mover will have no effect on revenues, but it is expected to save the firm $20,000 per year in before-tax operating costs, mainly labor. The firms' marginal tax rate is 40%. Assume that the net working capital investment will be recouped at the end of year 3. Question 1: What is the initial cash flow at t=0? Select one: O a. -$62,000 O b. $60,000 c. -$48,000 d. $50,000 e. -$52,000 Question 2: What is the operating cash flow in Year 1? Select one: O a. $12,000 O b. $15,920 O c. $19,920 O d. $31,800 O e. $20,000 Question 3: What is the total terminal (non-operating) cash flow at the end of Year 3? Select one: O a $20,000 O b. $13,680 O c. $15,680 O d. $22,000 e. $17,800 Question 4: Given that the operating cash flow for year 2 is $22,800, and the operating cash flow for year 3 is $15,600, what is the project's NPV if the project's cost of capital is 10%? Select one: O a $1,547 b. $5,712 O c. $2,917 d. -$1,049 O e. $8,453
