Transactions Through Third Parties
You may buy or sell shares through certain 401(k) plans, banks, broker-dealers,
financial advisors or other investment professionals. These organizations may
charge you a fee for this service and may have different policies. Some policy
differences may include different minimum investment amounts, exchange
privileges, fund choices and cutoff times for investments. The Fund is not

accept purchase or sale orders on the Fund's behalf.
