No. It is NOT TRUE at all. I have been an ASB account holder since 2002 with a capped savings at RM10,000. That was because i was still under 18-year-old then. I was allowed to increase my investment in ASB to a maximum of RM200,000 a few years later.

And for your information, we did not get 10% return since the late 90s. The best return for ASB was 12% or 13% but that was in the early 90s, so my mom said. And things work a bit differently for ASB compared to ASW2020 and ASM. For ASB there are dividend and bonus. The calculation for bonus is based on average of your total fund for the past 10 years. The dividend for last year was 7% only, and 1.75% for bonus. Each account holder will get a full 7% dividend but not the full 1.75% bonus unless you've been holding the same amount of fund in the last 10 years. So the bottom line is that we did not get 10%+ return as you claimed and ASNB also did not say about the 100% confirmed return. Where did you see this thing about 100% confirmed divided every year ? The ASNB only guaranteed that you won't loss your principle, just like many of the principle guaranteed funds out there offered by commercial banks and investment banks.
Just so you know, Bernard Madoff's ponzi scheme also offered his investors a guaranteed return of 5%/pa. Why only 5% ? According to New York Post, he offered only 5% return so people won't get suspicious of the investment scheme he was running 

Obviosly we need a finance guru to explain about how ASNB works
