In the case of upward conversion, the upward conversion of Class A is the same as the fixed conversion, and the agreed income is obtained by the share of the parent fund whose net value exceeds 1 yuan, and the share of Class B whose net value exceeds 1 yuan is converted into the parent fund. Folding up has no effect on Class A, but it will restore Class B to a higher initial net leverage.
Assuming that the discount of Class B is B net value ≤0.25 yuan, the discount date of Class B net value is 0.242 yuan, Class A net value is 1.036 yuan, and the parent fund net value is 0.639 yuan. Then every 1000 copies of Class B with a net value of 0.242 yuan will be converted into 242 new Class B with a net value of 1 yuan; Every 1000 A-class net worth 1.036 yuan is converted into 242 new A-class net worth 1 yuan and 1036-242=794 new parent fund net worth 1 yuan; Every 1000 parent fund with a net value of 0.639 yuan is converted into 639 new parent funds with a net value of 1 yuan.
When the discount approaches, the overflow value or discount of Class B funds that were originally traded at a premium or discount will be reduced to a quarter of the original value. For example, for Class B with an original spillover value of 0. 12 yuan, when the net value of 0.25 yuan is discounted, the transaction price is 0.28 yuan, and the spillover value is reduced to 0.03 yuan. Class B, originally traded at a discount value of 0.08 yuan, the discount price was 0.23 yuan when the net value was 0.25 yuan, and the discount value was reduced to 0.02 yuan. Class b, which was originally traded at parity, is still close to parity when there is a discount.
