THORNBURG FUNDS
Supplement to Institutional Class Shares Prospectus
November 2, 1998
This information supplements the Thornburg Funds Institutional
Class Shares Prospectus dated November 2, 1998.
The following information is added to the section entitled "Your
Account - Buying Fund Shares," which begins on page 25 of the
Prospectus:
Each Fund may authorize certain securities brokers to
accept on its behalf purchase and redemption orders
received in good form, and some of those brokers may
be authorized to designate other intermediaries to
accept purchase and redemption orders on the Fund's
behalf. Provided the order is promptly transmitted to
the Fund, the Fund will be deemed to have received a
purchase or redemption order at the time it is
accepted by such an authorized broker or its designee,
and customer orders will be priced based upon the
Fund's net asset value next computed after the order
is accepted by the authorized broker or its designee.
Investors may be charged a fee if they effect
transactions in Fund shares through a broker or agent.
