The operation of Class A and Class C shares is exactly the same, but the difference is that their rate structure is different, which provides a choice for investors who hold for a long time and band. Class A is the front-end fee, which is charged at the time of purchase. Category C does not charge subscription fees, but charges sales service fees, which are accrued from the net asset value of the fund on a daily basis. Generally, you can choose Class A for a long time and Class C for a short time.
