to all bros and sis here,
am relatively new in share trading. would like to seek further clarifications to the following:

I have 500shares of MAS
Announcement as follows:

Full Description:
Renounceable rights issue of new ordinary shares of RM1.00 each in Malaysian Airline System Berhad ("MAS") (Rights Shares) at an issue price of RM1.60 per rights share on the basis of one (1) rights share for every one (1) existing ordinary share of RM1.00 each held in MAS as at 5.00pm on 10 February 2010 ("Rights Issue")

Dispatch Date: 12/02/2010

Last Day and Time for:
- Sale of Provisional Allotment of Right: 22/02/2010 05:00PM

Can anybody simplify the above to laymen terms? Don't have a clue of rights and warrants thingy. Much help is appreciated.
My most curious Q would be:
Do i need to top up/additional payment to get the rights?
When can i dump the rights?

Thank you in advance.

I used that before, that's ok (I used MBB to be precise).
