The net asset value of a fund unit refers to the net asset value of the fund represented by each fund unit. Net asset value of fund unit = (fund assets-fund liabilities)/fund share. \x0d\ Cumulative net value of fund units refers to the net asset value of units without considering previous dividends since the establishment of the fund. It is equal to the current net asset value of the fund, plus the accumulated dividend amount distributed since the establishment of the fund, reflecting the asset appreciation of the fund since its establishment. Cumulative unit net value = unit net value after the establishment of the fund+cumulative unit dividend amount.
