The internal rate of return method is used by King Bros. Construction Co. in analyzing a capital expenditure proposal that involves an investment of $80,766 and annual net cash flows of $18,000 for each of the eight years of its useful life.

10	7.360	6.145	5.650	5.019	4.192

a. Determine a present value factor for an annuity of $1 which can be used in determining the internal rate of return. If required, round your answer to three decimal places.

b. Using the factor determined in part (a) and the present value of an annuity of $1 table above, determine the internal rate of return for the proposal. %

The capital investment committee of Ellis Transport and Storage Inc. is considering two investment projects. The estimated income from operations and net cash flows from each investment are as follows:

	Warehouse					Tracking Technology
Year	Income from Operations		Net Cash Flow			Income from Operations		Net Cash Flow
1	$57,200		$172,000			$120,000		$275,000
2	57,200		172,000			92,000		232,000
3	57,200		172,000			46,000		163,000
4	57,200		172,000			20,000		112,000
5	57,200		172,000			8,000		78,000
Total	$286,000		$860,000			$286,000		$860,000

Each project requires an investment of $520,000. Straight-line depreciation will be used, and no residual value is expected. The committee has selected a rate of 15% for purposes of the net present value analysis.

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
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

Required:

1a. Compute the average rate of return for each investment. If required, round your answer to one decimal place.

	Average Rate of Return
Warehouse	%
Tracking Technology	%

1b. Compute the net present value for each investment. Use the present value of $1 table above. If required, use the minus sign to indicate a negative net present value.

	Warehouse	Tracking Technology
Present value of net cash flow total	$	$
Less amount to be invested	$	$
Net present value	$	$

2. The warehouse has a net present value as tracking technology cash flows occur in time. Thus, if only one of the two projects can be accepted, the would be the more attractive.
