Past performance is no guarantee of future results. Investment return and the principal value of an investment will fluctuate. Shares may be worth more or less than original cost when redeemed.

This Fund may invest at least 80% of its assets in high-yield securities that are below investment grade but rated at least B by Moody's or S&P. Lower rated bonds generally involve a greater risk to principal than higher rated bonds. This Fund may also invest in mortgage-related securities, 15% in euro-denominated securities, without limit in U.S. dollar-denominated foreign securities, and up to 25% in derivatives. Foreign securities may entail greater risk due to foreign economic and political developments. Mortgage-backed securities are subject to prepayment risk and may be sensitive to changes in prevailing interest rates. When interest rates rise, the value of fixed income securities generally declines. This Fund may use these derivative instruments for hedging purposes or as part of its investment strategy. Use of these instruments may involve certain costs and risks such as liquidity risk, interest rate risk, market risk, credit risk, management risk and the risk that a fund could not close out a position when it would be most advantageous to do so. Portfolios investing in derivatives could lose more than the principal amount invested in those instruments.

Risk Section Source: IDS GmbH-Analysis and Reporting Services, an investment analysis and reporting service which is a subsidiary of Allianz SE. This section is based on the actual share class and measures volatility. The different elements comprising this section are explained below. The overall market is represented by the unmanaged index which is the fund? official benchmark in its prospectus. Beta measures the market related volatility of a portfolio. The beta of the market is 1 by definition. A beta greater than 1 indicates that a portfolio's market risk is greater than the overall market's, while a beta less than 1 indicates a lower market risk. It is important to note that having a low market risk does not necessarily imply low volatility. A portfolio may have a low beta while experiencing volatility due to factors independent of the market. R-squared measures the percentage of a portfolio's movements that are explained by movements in the overall market. Standard deviation is an absolute measure of volatility measuring dispersion about an average which, for a mutual fund, depicts how widely the returns varied over a certain period of time.

PIMCO's average credit quality statistic is intended to provide clients with helpful insight into a portfolio's sensitivity to changes in credit spreads. In general, instruments are weighted at their market value. Certain derivatives, such as swaps, are weighted at "bond equivalent value", which is the notional amount of the instrument adjusted by the current gain or loss on the position. The two "legs" of a swap are included separately in the calculation. The "risky" leg (e.g. the fixed leg for interest rate swaps or the reference entity for credit default swaps) is assigned a credit rating associated with the regional market (for interest rate swaps) or reference entity (for credit default swaps) of the instrument. The "floating" leg is assigned a short-term rating of A1/P1.
