Just want to share that I just surrendered my AIA Achiever recently.
Bought it 8 years ago.
Premium paid $48,000 for 8 years ($500 monthly)
Surrender Value $51,321.39
The charges are too high and I will not recommend it to anyone.
I just realised you are lucky to get your money back, check out this guy, also hold AIA Achiever for 8 years, lost money:
http://www.my15hourworkweek.com/2014/04/27/money-mistake-19-aia-achiever-plan/By the time I surrendered this policy in Feb this year, I had been holding this policy for 8 years and 1 month. That’s $9,700 poured in. But the withdrawal value was only about $8,900! Even if I had just put the money under my pillow for the past 8 years earning 0% interest, I would have been better off with an extra $800.

You don't seem to be able to comprehend a very simple assertion that the numbers do not add up.
