Conversion trigger date (T- 1): when the net value of Grade B is lower than 0.25, conversion will be triggered. On that day, Grade A and Grade B traded normally, and the parent fund applied for redemption normally.

Conversion base date (T): suspension of application for redemption of the parent fund; Shares A and B shall be suspended for one hour from 9: 30am to10: 30am, and resumed after10: 30am; Shares A and B shall be suspended for one hour from 13: 00 pm to 14: 00 pm, and resumed after 14:00 pm. At this point, the fund name will be preceded by "*". On this day, the B-base traded on the Shanghai Stock Exchange, that is, the variety starting with "50", will not carry "*", and will only suspend trading for one hour at 9: 30 am-10: 30 am.

After the close of the day, we can know that due to the conversion, the B share bought will lose money instantly without considering other factors:

Formula 1: The loss caused by discount is: premium rate * net value of B shares/closing price of B shares on the previous day (transaction price) Formula 2: The number of B shares after discount is: net value of B shares * original shares.
