Net present value method, present value index, and analysis for a service company Continental Railroad Company is evaluating three capital investment proposals by using the net present value method. Relevant data related to the proposals are summarized as follows: Maintenance Equipment Ramp Facilities Computer Network Amount to be invested $692,682 $452,204 $227,289 Annual net cash flows: Year 1 315,000 233,000 148,000 Year 2 293,000 210,000 102,000 Year 3 268,000 186,000 74,000 Present Value of $1 at Compound Interest Year 6% 10% 12% 15% 20% 1 0.943 0.909 0.893 0.870 0.833 2 0.890 0.826 0.797 0.756 0.694 3 0.840 0.751 0.712 0.658 0.579 4 0.792 0.683 0.636 0.572 0.482 5 0.747 0.621 0.567 0.497 0.402 6 0.705 0.564 0.507 0.432 0.335 0.665 0.513. 0.452 0.376 0.279 0.627 0.467 0.404 0.327 0.233 9 0.592 0.424 0.361 0.284 0.194 10 0.558 0.386 0.322 0.247 0.162 Required: 1. Assuming that the desired rate of return is 15%, prepare a net present value analysis for each proposal. Use the present value of $1 table above. If required, use the minus sign to indicate a negative net present value. If required, round to the nearest dollar. Total present value of net cash flow Maintenance Equipment Ramp Facilities Computer Network Less amount to be invested Net present value 2. Determine a present value index for each proposal. If retired, round your answers to two decimal places. Present Value Index Maintenance Equipment Ramp Facilities Computer Network 3. The computer network has the largest present value index. Although ramp facilities has the largest net present , as revealed by the present value value, it returns less present value per dollar invested than does the computer network indexes. The present value index for the maintenance equipment is less than 1, indicating that it does not meet the minimum
