Your company is considering investing in a process improvement that would require an initial capital investment of $300 K. The projected revenue over the next five years are as follows:

Year	Revenue ($K)
1	90
2	90
3	90
4	90
5	90

The company can always leave the capital investment in the stock portfolio, which is projected to yield 10% p.a. over the next five years.

Should the company invest this amount ($300 K) in the process improvement or leave it in the stock portfolio?
