1) Cooper and Morton, LLP, a law firm, is considering the replacement of its old accounting system with new software that should save $19,000 per year in net cash operating costs. The old system has zero disposal value, but it could be used for the next 12 years. The estimated useful life of the new software is 12 years with zero salvage value, and it will cost $190,000. The required rate of return is 14%.

Requirements:

1.	What is the payback period?
2.	Compute the NPV.
3.	Management is unsure about the useful life. What would be the NPV if the useful life were
	(a) 5 years instead of 12 or (b) 20 years instead of 12?
4.	Suppose the life will be 12 years, but the savings will be $15,000 per year instead of $19,000. What would be the NPV?
5.	Suppose the annual savings will be $16,000 for 8 years. What would be the NPV?
