The calculation formula is: the net asset value of a fund unit is equal to (total assets minus total liabilities) or the total number of fund units.

1. Among them, total assets refer to all assets owned by the fund, including stocks, bonds, bank deposits and other securities, etc.; total liabilities refer to the liabilities formed during the operation and financing of the fund, including Various expenses payable to others, interest on funds payable, etc.

2. The cumulative fund net value is equal to the sum of the unit net value and the cumulative dividends and dividends since the fund was established. It is a reference value. For example, for example: the net value of a certain fund unit on February 2, 2006 was 1.0486 yuan, and the cash dividend distributed in April 2006 was 0.025 yuan per fund unit, then the cumulative net value is equal to 1.0486 plus 0.025, which is equal to 1.0736 yuan.
