Clearcast Communications Inc. is considering allocating a limited amount of capital investment funds among four proposals. The amount of proposed investment, estimated Operating income, and net cash flow for each proposal are as follows: The company's capital rationing policy requires a maximum cash payback period of three years. In addition, a minimum average rate of return the remaining proposals. Present Value of $1 at Compound Interest \begin{tabular}{cccccc} \hline Year & 6% & 10% & 12% & 15% & 20% \\ \hline 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 \\ 7 & 0.665 & 0.513 & 0.452 & 0.376 & 0.279 \\ 8 & 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 \end{tabular} 5. Compute the present value index for each of the proposals in part (4). If required, round your answers to two decimal places. Select proposal to compute Present value index. Present value index (rounded) 6. Rank the proposals from most attractive to least attractive, based on the present values of net cash flows computed in part (4). Rank 1st Rank 2nd 7. Rank the proposals from most attractive to least attractive, based on the present value indexes computed in part (5). Rank 1st Rank 2nd 8. The analysis indicates that although Proposal has the larger net present value, it is not as attractive as Proposal in terms of the amount of present value per dollar invested. Proposal requires the larger investment. Thus, management should use investment resources for Proposal before investing in Proposal , absent any other qualitative considerations that may impact the decision
