The day of the ex-dividend day, that is, the ex-dividend benchmark day will appear ex-dividend offer, that is, the market closing price of the day before the benchmark day, minus the company should be paid cash dividends, which is the day of the ex-dividend day of the opening price of the reference price.
The ex-dividend quote will appear on the day called the ex-dividend base day.
Calculation of the ex-rights price, divided into three cases:
1. When the gift: ex-rights price = (closing price of the day before the ex-rights day) ÷ ( 1 + the rate of delivery).
2. In case of compensated allotment of shares; ex-rights price = ( closing price on the day before the ex-rights day + allotment price × allotment rate) ÷ (1 + allotment rate).
3. When combining share delivery and compensated allotment: Ex-rights price = closing price on the day before the ex-rights date = allotment price × allotment rate ÷ (1 + allotment rate + allotment rate)
If ex-rights and ex-dividend are carried out at the same time, the formula will be as follows: ex-rights and ex-dividend offer of the same day = (previous day's closing price - amount of dividend + allotment price × allotment rate) ÷ (1 + allotment rate + allotment rate)
