Expen
se Ex ample
As a shar eholder
of a Fund,
you incur two types
of costs:
(1) tr ansaction
costs ,
including
sales char ges (loads)
on pur chase
payments
(these
char ges vary among
the
shar e classes);
and (2) ongoing
costs , including
management
fees; distribution
and service
(12b-1)
fees (these
char ges vary among
the shar e classes);
and other Fund expenses
. This
Example
is intended
to help you under stand your ongoing
costs (in dollar s) of investing
in each Fund and to compar
e these costs with the ongoing
costs of investing
in other
mutual
funds .
The Example
is based
on an investment
of $1,000
invested
at the beginning
of the
period
and held for the entir e period
(November
1, 20 23 thr ough April 30, 20 24).
Actual
Expen
ses
For each class of each Fund, the fir st line of the applicable
table on the following
pages
pr ovides
information
about
actual
account
values
and actual
expenses
. You may use the
information
in this line, together
with the amount
you invested,
to estimate
the expenses
that you paid over the period.
Simply
divide
your account
value by $1,000
(for example,
an
$8,600
account
value divided
by $1,000
= 8.6), then multiply
the result by the number
in
the fir st line under
the heading
titled “Expenses
Paid During
Period 11/1/23
– 4/30/24”
to
estimate
the expenses
you paid on your account
during
this period.
Hypothetical
Example
for
Compari
son
Purposes
For each class of each Fund, the second
line of the applicable
table on the following
pages pr ovides
information
about hypothetical
account
values
and hypothetical
expenses
based
on the Fund’s
actual
expense
ratio and an assumed
rate of return of 5% per year
befor e expenses
, which
is not the Fund’s
actual
return.
The hypothetical
account
values
and expenses
may not be used to estimate
the actual
ending
account
balance
or expenses
you paid for the period.
You may use this information
to compar
e the ongoing
costs of
investing
in each Fund and other funds . To do so, compar
e this 5% hypothetical
example
with the 5% hypothetical
examples
that appear
in the shar eholder
reports
of the
other funds .
