There are several fees for maintaining and adminstratoring the MPF Funds, viz. Custodian Fee, Management Fee and Administration Fee. Different funds may have different rate of Mangement fee subject to which fund house that you are selected. You cannot see the related fee from your statement as the fee has been absorbed from your investment fund prior to the investment.
For example, if the fund portfilio consists of two funds - one is conservative fund (like Bonds) and the other is relatively aggressive fund (e.g HK Equity). The Management and Admin fee of the latter is most likely higher than the former one. Hence, you have to check firstly before making the decision.
