This calculation uses the formula:

                         P ( 1 + T ) /\  n  =  ERV

Where:

                         P            = A hypothetical initial payment of:            $1,000
                                      = ERV(0)

                         T            = Average annual total return
                                      = ((ERV(10)/P) /\ (1/10)) -1

                         n            = Number of years

                         ERV(n)       = Ending redeemable value at the end of year n
                                      = ERV(n-1) x ((b/a) - c)            for n = 1 to 9
                                      = ERV(9) x ((b/a) - c) - (d x P)    for n = 10

Non-Standard Average Annual Total Return *

The non-standard average annual total return is calculated in the same manner as
the standard average annual total return except that the withdrawal charge
percentage will be assumed to be 0%.
