Trailing commission, also known as custody service fee, is the fee paid by the fund company to the sales organization to maintain the total amount of the fund, and its amount is calculated according to the holding time or market value of the fund share. The product provider collects fees from the customer's assets and returns them to the investment consultant in the form of commission.

The sales service fee refers to a certain percentage of the expenses accrued by the fund manager from the open-end fund property according to the agreement of the fund contract and the relevant laws and regulations in force at that time, which is used to pay the commission of the sales organization, the marketing expenses of the fund and the service fee of the fund share holders.

The fund management fee is the management remuneration paid to the fund manager, and its amount is generally extracted from the fund assets according to a certain proportion of the net asset value of the fund. Fund manager is the manager and user of fund assets, which plays a decisive role in maintaining and increasing the value of fund assets. Therefore, the proportion of fund management fees charged is higher than other expenses. Fund management fee is the main source of income for fund managers, and fund managers' fees cannot be spread into funds or fund companies, nor can they be charged to investors.

The fund custody fee refers to the fee charged by the fund custodian to provide services for the fund. Custody fees are usually drawn according to a certain proportion of the fund's net asset value, calculated and accumulated daily, and paid to the custodian at the end of each month. This fee is also paid from the fund assets and does not need to be charged to investors separately. The custody fee of the fund is included in the fixed cost. The proportion of fund custody fees is related to the size and location of the fund. Usually, the larger the fund scale, the lower the fund custody fee rate.

Fund management fees and custody fees are the remuneration received by managers and custodians for providing services to the fund, and are the business income of managers and custodians. The management fee and custody fee rates are generally agreed in the fund contract or the articles of association of the fund company after being approved by the fund supervision department, and shall not be changed at will. Expenses incurred by fund managers and custodians due to non-performance or incomplete performance of obligations or loss of fund assets, as well as expenses incurred due to handling matters unrelated to fund operation, shall not be included in fund management fees and custody fees.
