The transaction price of closed-end funds is the market price that has been confirmed at the time of transaction; In contrast, the unit transaction price of open-ended funds depends on the net asset value of unit funds that are not known at the time of subscription and redemption (but can be calculated after the market closes on the day and announced on the next trading day).

Fund income distribution refers to the distribution of the net income of the Fund to fund holders in proportion to the number of fund units held.

If there is still any surplus after the fund's loss has been fully made up, the current year's income can be distributed. If the Fund suffers losses in the current year and has no net income, no income distribution shall be made.
