2. In order to assess the adequacy of your fund, I made the following assumptions to help
me build an effective model :
You will be the only one drawing from the pension fund when you retire
The current fund value is assuming all interest payments have be accounted
for.
No inflation
Your postretirement income is inclusive of tax, and it is 60% of your income
today.
Our major assumption was that Bob’s ultimate goal was to find out at what reasonable
retirement age he would realize the highest value of his retirement fund.
