Unit net value, that is, the net asset value of each fund share, is an indicator of fund performance and also the transaction price of open-end funds. The calculation formula of unit net value is: Net unit value = (total assets-total liabilities)/total fund shares. Total assets refer to the total assets of the fund, including stocks, bonds, bank deposits and other securities. Total liabilities refer to liabilities arising from fund operation, including various expenses payable.

The cumulative net value of fund units is the sum of the net value of fund units and the cumulative dividend amount of units after the establishment of the fund, which reflects all the income since the establishment of the fund. Cumulative net value of fund unit = net value of fund unit+cumulative dividend amount of unit in the history of fund (sum of all dividend amounts in the history of fund/total share of fund)

The price of closed-end funds includes the issue price in the primary market and the transaction price in the secondary market. The issue price of a fund refers to the price determined by the fund issuer to sell the fund shares to the fund investors when the fund is issued; Fund market price refers to the price at which fund investors buy and sell fund shares in the securities market. The price of open-end fund refers to the price at which fund holders buy or redeem fund shares from fund companies, which is calculated based on the net asset value of the fund.
