YES is inder YTL Communications & itself is under YTLPower........however I think both YTLE & YTLPower are interrelated. Mind you YTLE has the 2.3GHz Worldwide Interoperability for Microwave Access (WiMAX) spectrum in Peninsular Malaysia which YTLPower doesn't have. According to my sources, YTLPower paid & provide all the infrastructure [ very expensive] & YTLE provide the  Wimax spectrum [ the incubator].......so it 60:40 percentage on profits.......could someone me please correct me if I am wrong. If I were you I would go for YTLE shares........more power so to say.
Cheers brother SuperToi........you have a great weekend too.
