The description of the investment policies of the Portfolios listed above
(collectively, the "Portfolios") is revised as follows:
On September 1, 1998, the Malaysian government announced a series of
capital and foreign exchange controls on the Malaysian currency, the ringgit,
and on transactions on the Kuala Lampur Stock Exchange, that operate to severely
constrain or prohibit foreign investors, including the corresponding series (the
"Series") in which the Portfolios invest their assets, from repatriating assets.
While there is some confusion in the market concerning the interpretations of
these changes, it appears that the Portfolios and Series will not be permitted
to convert the proceeds of the sale of their Malaysian investments into U.S.
dollars prior to September 1, 1999.
As a consequence of these developments, the Portfolios and Series have
stopped trading securities in Malaysia. With respect to the current Malaysian
investments owned by the Portfolios and Series, the Portfolios and Series are
presently valuing the securities in good faith at fair value by discounting the
current market prices of the Malaysian securities and discounting the U.S.
dollar-ringgit currency exchange rate. Pending further clarification from
Malaysian regulatory authorities regarding the controls identified above, the
Portfolios and Series will treat their investments in Malaysian securities as
illiquid.
The Pacific Rim Small Company Portfolio has ceased selling its shares until
the scope and application of the exchange controls are clarified. The
International Small Company Portfolio, which has invested in the Pacific Rim
Small Company Series, will continue to sell its shares but has discontinued
further investing in the Pacific Rim Small Company Series.
