I go to google read some explanation for below Bonus/Dividend etc nouns ,
for double confirm I am not misunderstand , pls help me to correct it if i am worng.

Let assume the STOCK Price is RM1.00 , and i have 1000unit , is the Stock Par Value is RM0.50

First & Final Dividend 10% T.E
== That means base on the Ex-date Stock Price RM1.00 , I can get the dividend RM1000 x 0.1 x 0.5 = RM50 (TE means no tax at all)

Interim Dividend 1 sen T.E
== That means I can get 1sen x 1000units = RM10 (No Tax)

First & Final Dividend 2.5 Sen T.E
== That means I can get 2.5sen x 1000units = RM25 (No Tax)

Final Single Tier Dividend 2.5 Sen
== That means I can get 2.5sen x 1000units = RM25 , but TAX 26% x RM25 = RM6.5 (Tier = TAX 26%?), Finally i get RM25-RM6.5 = RM19.5

Bonus Issue 1 : 1
== Means i get the another 1000units shares , but the price will divided by 2 ,
but i dont know how they decide when the stock price to divide?

Rights Issue 3 : 1
I am no idea what rights issues is @@

Share Split 2:
== Means my shares will split from 1000unit to 2000units too~
but the price still will divided by 2 , what different between Bonus Issue 1:1 ?

Thank you !!!!!!!!!!!
