4. Which of the following SHOULD be included in a project's free cash flow calculations?

investment in working capital

sunk costs

allocated overhead expenses

noncash revenues of the company's nearest competitor

Probability Return % 0.30 60 0.50 20 0.20 10

Explanation / Answer

1)

expected return for A=0.30*60%+0.50*20%+0.20*10%=18%+10%+2%=30%=0.30

variance for Stock A = 0.30*(0.60-0.30)^2+0.50*(0.20-0.30)^2+0.20*(0.10-0.30)^2

variance for Stock A = 0.30*(0.30)^2+0.50*(0.10)^2+0.20*(0.20)^2

variance for Stock A = 0.30*(0.09)+0.50*(0.01)+0.20*(0.04)=0.04

=>standard deviation for Stock A=sqrt(variance)=sqrt(0.04)=0.20=20%

2)Large US stocks

Large US stocks had the greatest average return and greatest volatility based on historical data from 1926 to the present as compared to other asset classes.

4) investment in working capital

investment in working capital SHOULD be included in a project's free cash flow calculations as these affect the cash flows of the firm.
