The growth rate of fund unit net value refers to the growth rate of fund unit net value at the end of the period relative to the beginning of the period. According to the relevant regulations of China Securities Regulatory Commission, the formula for calculating the growth rate of fund unit net value is: current unit net value growth rate = (net asset value of unit fund before the first dividend in the current period ÷ net asset value of unit fund at the beginning) ×××× (net asset value of unit fund at the end of the period ÷ net asset value of unit fund after the last dividend in the current period). -1 in which: (1) The net asset value of the fund shares before dividends is calculated according to the net asset value of the fund shares on the trading day before the ex-dividend date; (2) Net asset value of the fund unit after dividend = Net asset value of the fund unit before dividend-dividend amount of the unit; (3) the net asset value of the fund unit before raising = the net asset value of the fund on the trading day before the ex-dividend date of the paid-in fund ÷ the total share of the fund before raising; (4) Net asset value of fund unit after raising = (net asset value of paid-in fund on the trading day before ex-dividend date+raised amount+frozen interest during raising period+balance of raising expenses) ÷ Total fund share after raising (5) Net asset value of initial fund unit established during the calculation period = (paid-in fund on establishment date+frozen interest not converted into fund share during issuance period+balance of closed-end fund issuance expenses) ÷ Total fund unit share on establishment date.
