Because the back-end charges increase with the number of years, the reduction of the handling fee refers to the holding time. The holding period of funds purchased several times in the future can only be counted from the time of purchase, so when redeeming together, you need to find a fund contract to charge by file.
According to the rate design scheme of open-end funds, the redemption rate of many funds decreases with the extension of investors' holding period, and is redeemed in a first-in-first-out manner. The so-called first-in-first-out method refers to determining the holding time of the redeemed fund shares according to the principle of redeeming the purchased fund shares first when calculating the redemption fee, so as to determine its corresponding rate.
