Please carefully consider the William Blair Funds’ investment objectives, risks, charges, and expenses before investing. This and other information is contained in the Funds’ prospectus and summary prospectus, which you may obtain by calling 1-800-742-7272.

The William Blair Funds are distributed by William Blair & Company, L.L.C., member FINRA/SIPC.
Risks: The Fund involves a high level of risk and may not be appropriate for everyone. The Fund’s return will vary, and you could lose money by investing in the Fund. Investing in the bond market is subject to certain risks including market, interest rate, issuer, credit, and inflation risk. Rising interest rates generally cause bond prices to fall. Sovereign debt securities are subject to the risk that an entity may delay or refuse to pay interest or principal on its sovereign debt because of cash flow problems, insufficient foreign reserves, or political or other considerations. 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. Investing in foreign denominated and/or domiciled securities may involve heightened risk due to currency fluctuations, and economic and political risks. These risks may be enhanced in emerging markets. Derivatives may be subject to certain risks such as leveraging, liquidity, interest rate, credit, counterparty, management and the risk of mispricing or improper valuation. The Fund is non-diversified and may be more susceptible to adverse developments affecting any single issuer held by the Fund.

The JP Morgan Emerging Markets Bond Index (EMBI) Global Diversified tracks the total return of U.S.-dollar denominated debt instruments issued by sovereign and quasi-sovereign entities. The index is unmanaged, does not incur fees or expenses, and cannot be invested in directly.

The Morningstar Emerging Markets Bond category represents the average annual composite performance of all mutual funds listed in the Emerging Markets Bond category by Morningstar.
The Morningstar Rating for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange- traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product’s monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10 year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods.
