This is taken from a CFAI mock:
[question removed by moderator] Question: Did he come up with this range by adding: 4% (contribution) + 2.5% (expense growth) + 1% (inflation)****I’m trying to make it simple so I’m not using geometric return … I thought 4% is 25% of annual operating budget, then 4%/25% = 16% should be the budget or what? - To meet the endowment’s spending needs for this year, the liquidity need is in the range of 4.5% –5% of the year-end portfolio value. Question: is this range = 2.5% + 1 + 0.65% or what? I got confused by the wording 25% of annual operating budget … Thanks,
