From the 1st page quote
"The last day of trading to receive the dividend. It is one trading day before the ex-dividend date, where the stock is said to be "cum dividend" (in other words, the stock that you hold comes with the dividend).
Existing shareholders and anyone who buy and hold the stock on this day (i.e. until the end of that particular trading day e.g. 5:00pm) will receive the dividend. Even if you bought the shares at 4:59pm on the last in-dividend date, you are still entitled as you held the shares until the ex-date.
After this date, the stock becomes ex-dividend"
