Since 2009, the index of "customer service fee" has been added to the annual report of fund companies, which mostly counts the fees paid by fund companies to banks for selling funds, which is also commonly known as "trailing commission".

Generally, when the market is relatively poor, it is necessary for banks to maintain a certain share through various means. This is the need to give silver trailing commission in the next few years.

It is said that some small companies now have new hairstyle funds, and all the management fee income within one year is given to the bank as a trailing commission, that is, issuing a new fund may not necessarily get actual income within one year.
