Question 1109512
Annual means that our t (time) = 4 (4 quarters in a year). Thus, our interest is 0.08/4 = 0.02.
Just after interest is credited, an expense charge equal to 0.4% of the fund is withdrawn, leaving us with 99.6% of the money or 0.996. So, after this withdrawal our money becomes: 
(1.02 x 0.99.6)^4 = 1.0652 which makes the effective annual interest rate 6.52%
