I also find it very strange... Nevertheless, get dividend = good news for investors.
I wonder if the 3rd Interim Dividend will be paid based on Mother Share + Exercised Rights ?

It is not strange.

It is normal for reit to give dividend prior before private placement or right issue.
As those income is generated before new shares being issued. So previous shareholders should get those income as dividend.

It is unfair for newly shareholders (from the RI) get enjoy the previous income generated prior before they subscribe the RI. 

As newly dividend payout will be diluted by new shares issued.

Why?

they cannot find others tax to replace this mah ....... unless GST inforce then may got hope ...... Gov always cut here increase there so at the end all same, only different group of income earners will change from here and there .... IMHO only .... 

dunno what mean.
Just know we all need to pay this 10% withholding tax for any Malaysia Reit dividend. And it cannot be claimed back even if you earn RM1/month. 

sunreits paying dividend every quarter.
Others Reits normally paying dividend every 6 months. At least getting above 5% dividend .
