The net asset value of a fund is the balance of the total market value of the fund assets minus its liabilities. The total market value of fund assets refers to the total assets of all assets (including stocks, bonds, bank deposits and other securities) owned by the fund at a certain point in time; Liabilities are the expenses and interests that the fund must pay to others in the process of operation and financing.

The net asset value of a fund unit refers to the net asset value of a fund represented by each fund unit, and the calculation formula is: net asset value of a fund unit = (total assets-total liabilities)/total number of fund units.
