Loomis Sayles Investment Grade Bond Fund invests primarily in investment-grade fixed-income securities, although it may invest up to 10% of its assets in lower-rated fixed income securities.

While they can potentially enhance returns, lower-rated fixed-income securities are also considered riskier than investment-grade securities because there is a greater rate of default among the issuers of such securities. Mutual funds that invest in bonds can lose their value as interest rates rise, and an investor can lose principal.

The fund is structured with a benchmark aware risk and return objective. Individual investment ideas are evaluated based on investment return potential and contribution to portfolio risk. Portfolio construction is driven by bottom-up security selection and top-down macroeconomic analysis. We believe the resulting portfolio is well diversified and positioned to generate strong long-term risk-adjusted investment performance.

Because the Fund can invest a significant percentage of assets in foreign securities the value of the Fund shares can be adversely affected by changes in currency exchange rates, political, and economic developments. In emerging markets these risks can be significant. The Fund is subject to currency risk, which is the risk that fluctuations in exchange rates between the U.S. dollar and foreign currencies may cause the value of a Fund's investments to decline. Funds that invest in securities denominated in, or receive revenues in, foreign currency are subject to currency risk. Accordingly, the purchase of fund shares should be viewed as a long-term investment.

Because the Fund can invest a significant percentage of assets in debt securities that are rated below investment grade the value of fund shares can be adversely affected by changes in economic conditions or other circumstances. These events could reduce or eliminate the capacity of issuers of these securities to make principal and interest payments. Lower rated debt securities have speculative characteristics because of the credit risk of their issuers and may be subject to greater price volatility than higher rated investments. In addition, the secondary market for these securities may lack liquidity which, in turn, may adversely affect the value of these securities and that of the Fund. Accordingly, the purchase of fund shares should be viewed as a long-term investment.
