The management of Revco Products is exploring four different investment opportunities. Information on the four projects under study follows:

Project Number

	1			2			3			4
Investment required	$	(640,000	)	$	(590,000	)	$	(440,000	)	$	(530,000	)
Present value of cash inflows at a 9% discount rate		704,620			661,810			528,465			680,400
Net present value	$	64,620		$	71,810		$	88,465		$	150,400
Life of the project		7 years			14 years			7 years			4 years
Internal rate of return		12%			11%			15%			21%

Because the companys required rate of return is 9%, a 9% discount rate has been used in the present value computations above. Limited funds are available for investment, so the company cant accept all of the available projects.

Compute the project profitability index for each investment project.

Rank the four projects according to preference, in terms of net present value, project profitability index and internal rate of return.
