Providers often use a Management Expense Ratio (MER) to produce a single figure of expenses so that you or your adviser can compare products quickly and easily. Members of the Investment Savings and Insurance Association (ISI) are obliged to give MERs for most of their products. Non-members (such as banks) do not have to. Sometimes a measure called the Ongoing Management Charge (OMC) is used for a similar purpose.
The MER is usually quoted as a percentage of the product’s assets. However, MERs are not always successful in providing a complete comparison between products. That’s because:
While MERs are not perfect, they are the only industry tool that attempts to compare the fee structures of different products. Therefore, you should always ask to see the MER if it is available.
