Jennifer, a senior project manager, estimated net cash flow after taxes (CFAT) for a large project she is working on. The additional CFAT of $2,800,000 in year 10 is the salvage value, estimated at 9% of the $31 million first cost for all capital assets.


The PW value at the current MARR of 7% per year is

PW = ?31,000 + 5400(P?A,7%,6) + 2040(P?A,7%,4)(P?F,7%,6) + 2800(P?F,7%,10) = $767

Jennifer believes the MARR will vary over a relatively narrow range, as will the CFAT, especially during the out years of 7 through 10. She is willing to accept the other estimates as certain. Use the following probabil­ity distribution assumptions for MARR and CFAT to perform a simulation—hand- or spreadsheet-based.
MARR. Uniform distribution over the range 6% to 10%.
CFAT, years 7 through 10. Uniform distribu­tion over the range $1,600,000 to $2,400,000 for each year.
