PERFORMANCE INFORMATION
AVERAGE ANNUAL TOTAL RETURN. The Fund may from time to time advertise its
average annual total return. Average annual total return is determined
separately for Class A, Class B, Class C and Class Z shares.
Average annual total return is computed according to the following formula:
P(1+T)to the power of n = ERV
Where: P = a hypothetical initial payment of $1000.
T = average annual total return.
n = number of years.
ERV = ending redeemable value at the end of the 1, 5 or 10 year periods
(or fractional portion thereof) of a hypothetical $1000 payment
made at the beginning of the 1, 5 or 10 year periods.
Average annual total return takes into account any applicable initial or
deferred sales charges but does not take into account any federal or state
income taxes that may be payable upon redemption.
The average annual total return of the Class A shares for the one year, five
year and since inception (July 24, 1992) periods ended October 31, 1998 was
(34.35)%, (8.38)% and (0.03)%, respectively, and for the Class B shares, was
(36.34)%, (8.36)% and 0.08%, respectively, for the same periods. The average
annual total return for Class C shares for the one year and since inception
(August 1, 1994) periods ended October 31, 1998 was (32.44)% and (11.79)%,
respectively. The average annual total return for Class Z shares for the one
year and since inception (March 1, 1996) periods ended October 31, 1998 was
(30.67)% and (17.08)%, respectively.
YIELD. The Fund may from time to time advertise its yield as calculated over
a 30-day period. Yield is calculated separately for Class A, Class B, Class C
and Class Z shares. This yield will be computed by dividing the Fund's net
investment income per share earned during this 30-day period by the maximum
offering price per share on the last day of this period. Yield is calculated
according to the following formula:
YIELD = 2[( a - b +1)to the power of 6 - 1]
-----
cd
Where: a = dividends and interest earned during the period.
b = expenses accrued for the period (net of reimbursements).
c = the average daily number of shares outstanding during the period that
were entitled to receive dividends.
d = the maximum offering price per share on the last day of the period.
Yield fluctuates and an annualized yield quotation is not a representation
by the Fund as to what an investment in the Fund will actually yield for any
given period. Yields for the Fund will vary based on a number of factors
including changes in net asset value, market conditions, the level of interest
rates and the level of Fund income and expenses.

AGGREGATE TOTAL RETURN. The Fund may also advertise its aggregate total
return. Aggregate total return is determined separately for Class A, Class B,
Class C and Class Z shares.
Aggregate total return represents the cumulative change in the value of an
investment in the Fund and is computed according to the following formula:
ERV - P
-------
P
Where: P = a hypothetical initial payment of $1000.
ERV = ending redeemable value at the end of the 1, 5 or 10 year periods
(or fractional portion thereof) of a hypothetical $1000 payment
made at the beginning of the 1, 5 or 10 year periods.
Aggregate total return does not take into account any federal or state
income taxes that may be payable upon redemption or any applicable initial or
contingent deferred sales charges.
The aggregate total return for Class A shares for the one year, five year
and since inception (July 24, 1992) periods ended October 31, 1998 was (15.53)%,
(32.21)% and 9.29%, respectively, and for Class B shares was (16.32)%, (34.65)%
and 4.32%, respectively, for the same periods. The aggregate total return for
Class C shares for the one year and since inception (August 1, 1994) periods
ended October 31, 1998 was (16.32)% and (38.45)%, respectively. The aggregate
total return for Class Z shares for the one year and since inception (March 1,
1996) periods ended October 31, 1998 was (15.36)% and (35.89)%, respectively.
