CHANGES TO PRINCIPAL INVESTMENTS AND STRATEGIES
Effective on or around November 1, 2000, the description of PIMCO
International Growth Fund under "Principal Investments and Strategies" in the
Fund's Fund Summary is amended to read in its entirety as follows:
The Fund seeks to achieve its investment objective by
normally investing at least 65% of its assets in an
international portfolio of common stocks and other equity
securities of companies located outside of the United
States. Although the Fund normally invests in issuers from
at least five different countries, it may at times invest
in fewer than five countries, or even a single country. The
Fund typically invests in approximately 50 to 60 stocks,
with each stock usually constituting from 1.25% to 4.0% of
the Fund's portfolio. The Fund may invest in both developed
and developing, or "emerging," markets. The Fund has no other
prescribed limits on geographic asset distribution and may
invest in any foreign securities market in the world. The
Fund may also invest in securities of foreign issuers
traded on U.S. securities markets, but will normally not
invest in U.S. issuers. The Fund invests most of its assets
in foreign securities which trade in currencies other than
the U.S. dollar and may invest directly in foreign
currencies.
The portfolio manager selects securities for the Fund using
the Sub-Adviser's "Best Research" investment style. The
Best Research style uses a research-driven "bottom-up"
approach that seeks to utilize the Sub-Adviser's global
research capabilities to identify companies with above-
average long-term growth prospects and attractive
valuations and that possess a sustainable competitive
advantage, such as superior or innovative products,
personnel and distribution systems. The portfolio manager
seeks to select those stocks with the best long-term
performance expectations, using a broad range of company
fundamentals, such as long-term growth prospects, price-to-
earnings ratios and other valuation measures, dividend and
profit growth, balance sheet strength and return on assets.
The portfolio managers sell stocks in order to adjust or
rebalance the Fund's portfolio and to replace companies
with weakening fundamentals.
The Fund may utilize foreign currency exchange contracts
and derivative instruments (such as stock index futures
contracts) primarily for portfolio management and hedging
purposes. The Fund may also invest in equity securities
other than common stocks (such as equity-linked securities,
preferred stocks and convertible securities) and may invest
up to 10% of its assets in other investment companies. In
response to unfavorable market and other conditions, the
Fund may make temporary investments of some or all of its
assets in foreign and domestic fixed income securities and
in equity securities of U.S. issuers. This would be
inconsistent with the Fund's investment objective and
principal strategies.
Change in Investment Objective
Effective on or around November 1, 2000, the Fund intends to change its
investment objective to read as follows: "Seeks capital appreciation."
EXPECTED CHANGES IN SUB-ADVISORY ARRANGEMENTS
Subject to the approval of the shareholders of the Fund, beginning on or
around November 1, 2000 PIMCO Advisors intends to retain PIMCO/Allianz
International Advisors LLC ("PAIA") as the sub-adviser to the Fund. PAIA is a
wholly owned subsidiary of PIMCO Advisors. As sub-adviser, PAIA will have full
investment discretion
<PAGE>
and will make all determinations with respect to the investment of the Fund's
assets. Summary information about PAIA and the individuals who will have primary
investment management responsibility for the Fund is provided below.
