Investors should consider the investment objectives, risks, charges and expenses of the funds carefully before investing. This and other information are contained in the fund’s prospectus and summary prospectus, if available, which may be obtained by contacting your investment professional or PIMCO representative or by visiting www.pimco.com. Please read them carefully before you invest or send money.

Past performance is not a guarantee or a reliable indicator of future results. The performance figures presented reflect the total return performance for the institutional Class shares (after fees) and reflect changes in share price and reinvestment of dividend and capital gain distributions. All periods longer than one year are annualized. The minimum initial investment for Institutional class shares is $1 million; however, it may be modified for certain financial intermediaries who submit trades on behalf of eligible investors.

Investments made by a Fund and the results achieved by a Fund are not expected to be the same as those made by any other PIMCO-advised Fund, including those with a similar name, investment objective or policies. A new or smaller Fund’s performance may not represent how the Fund is expected to or may perform in the long-term. New Funds have limited operating histories for investors to evaluate and new and smaller Funds may not attract sufficient assets to achieve investment and trading efficiencies. A Fund may be forced to sell a comparatively large portion of its portfolio to meet significant shareholder redemptions for cash, or hold a comparatively large portion of its portfolio in cash due to significant share purchases for cash, in each case when the Fund otherwise would not seek to do so, which may adversely affect performance.

Differences in the Fund’s performance versus the index and related attribution information with respect to particular categories of securities or individual positions may be attributable, in part, to differences in the pricing methodologies used by the Fund and the index.

There is no assurance that any fund, including any fund that has experienced high or unusual performance for one or more periods, will experience similar levels of performance in the future. High performance is defined as a significant increase in either 1) a fund’s total return in excess of that of the fund’s benchmark between reporting periods or 2) a fund’s total return in excess of the fund’s historical returns between reporting periods. Unusual performance is defined as a significant change in a fund’s performance as compared to one or more previous reporting periods.

Past rankings are no guarantee of future rankings. Fund rankings: 1Yr. 1 out of 129; 5Yrs. 1 out of 81; 10 Yrs. 1 out of 42. Lipper Ranking for the Ultrashort Obligation Funds category as of 30 September 2017 for the Institutional Class Shares; other classes may have different performance characteristics. The Lipper Rankings are calculated by Lipper, Inc and are based on the total return performance, with distributions reinvested and operating expenses deducted. Rankings begin with the inception of the actual share class. Lipper does not take into account sales charges.

A word about risk: Investing in the bond market is subject to risks, including market, interest rate, issuer, credit, inflation risk, and liquidity risk. The value of most bonds and bond strategies are impacted by changes in interest rates. Bonds and bond strategies with longer durations tend to be more sensitive and volatile than those with shorter durations; bond prices generally fall as interest rates rise, and the current low interest rate environment increases this risk. Current reductions in bond counterparty capacity may contribute to decreased market liquidity and increased price volatility. Bond investments may be worth more or less than the original cost when redeemed. Investing in foreign denominated and/or domiciled securities may involve heightened risk due to currency fluctuations, and economic and political risks, which may be enhanced in emerging markets. Mortgage and asset-backed securities may be sensitive to changes in interest rates, subject to early repayment risk, and their value may fluctuate in response to the market’s perception of issuer creditworthiness; while generally supported by some form of government or private guarantee there is no assurance that private guarantors will meet their obligations. High-yield, lower-rated, securities involve greater risk than higher-rated securities; portfolios that invest in them may be subject to greater levels of credit and liquidity risk than portfolios that do not. Equities may decline in value due to both real and perceived general market, economic, and industry conditions. Swaps are a type of derivative; swaps are increasingly subject to central clearing and exchange-trading. Swaps that are not centrally cleared and exchange-traded may be less liquid than exchange-traded instruments. Derivatives may involve certain costs and risks such as liquidity, interest rate, market, credit, management and the risk that a position could not be closed when most advantageous. Investing in derivatives could lose more than the amount invested. Diversification does not ensure against loss.

There is no guarantee that these investment strategies will work under all market conditions or are suitable for all investors and each investor should evaluate their ability to invest long-term, especially during periods of downturn in the market. Investors should consult their investment professional prior to making an investment decision.
