Fund conversion is mainly aimed at graded funds, and the main shares of graded funds are: parent fund, class A share and class B share. If the fund is not listed, the net value of Class B shares in regular conversion exceeds 1, and the conversion at this time is dividend. If it is converted irregularly, if there is a net increase, it is also a dividend. If the net value starts to fall below 0, there will be a loss.
