Really doesn't have much to do with present values For the retail investor it follows two stages.
Stage 1
The asset management company charges typically 0.75% PA. This can be higher but this is the standard rate on Irish managed funds and is the rate charged to institutional investors eg charities, large pension funds etc. This is charged internally on the total asset value of the fund at each valuation date. This can be accrued daily, monthly, quarterly. Roughly speaking, if you were to take the average asset value of the fund over the year and calculate 0.75% you wouldn't be two far away (however its important to note that this might not be the case over the past 24 months given volatility in asset prices)
Exact calc: management fee /365 X Daily asset valuation (AUM)
This is accrued daily and will give you the exact fee and is typically charged quarterly
Stage 2
Retail investors(joe bloggs) pay around 1.5% management fee and also pays as much as 3% on each cashflow e.g each time you pay money in they charge you 3% on that amount.
This added charge is not a managment fee per se although that may be what its described as. This is used primarily to pay the commission to independent brokers and banks who sell the product to you and I. To a lesser extent this also covers the added admin costs that arise from small investments (retail).
This really is commission (if you invest enough they may waive some of it) I would say its extortionate but thats just my opinion. you can invest in Rabbo funds at an institutional fee and they offer superior products than are typically offered in the Irish market place, however YOU have to decide what you want to invest in.
There is a big difference between the unit price on the asset manager quotes and the unit price that you recieve because of all the additional charges
The extra commission that is charged in a way pays for the investment advice you recieved from your financial advisor or bank representitive- so I hope it was correct and competent advice. God knows you pay enough for it!
Apologies if I seem patronising with all the examples but I think it helps illustrate the points better.
