How to calculate ASB Dividend and Bonus

I have been told that ASB Dividend and Bonus are calculated as follows:

Dividend

Formula : (total minimum monthly balance) x dividend /12

Let’s say you invest $200 every month from 0, and dividend for that year is 7% (last year 2008 dividen), your dividend will be…

(200+400+600+800+1000+1200+1400+1600+1800+2000+2200+2400) x 0.07 / 12 = RM91

Bonus

Formula : (total minimum monthly balance) x bonus / 120

Let’s say you invest $100 every month from 0, and bonus for that year is 1%, your bonus will be…

(200+400+600+800+1000+1200+1400+1600+1800+2000+2200+2400) x 0.01 / 120= RM1.3

I'm not it is correct either.
