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. Read the prospectus and summary prospectus carefully before investing. Investing includes the risk of loss.

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. You should only consider it for the aggressive portion of your portfolio. The Fund’s returns will vary, and you could lose money by investing in the Fund. The Fund holds equities which may decline in value due to both real and perceived general market, economic, and industry conditions. Investing in securities of smaller companies tends to be more volatile and less liquid than securities of larger companies. International investing involves special risk considerations, including currency fluctuations, higher volatility, lower liquidity, economic and political risk. Investing in emerging markets can increase these risks. The securities of emerging market companies may be subject to greater volatility and less liquidity than companies in more developed markets. Individual securities may not perform as expected or a strategy used by the Adviser may fail to produce its intended result. Currency rates may fluctuate significantly over short periods of time and may reduce the returns of a portfolio. Convertible securities may be called before intended, which may have an adverse effect on investment objectives.

Top ten holdings are shown as % of total net assets. Sector and market-cap diversification exclude cash equivalents. Information about the Fund’s holdings should not be considered investment advice. There is no guarantee that the Fund will continue to hold any one particular security or stay invested in any one particular sector. Holdings are subject to change at any time.

The Morgan Stanley Capital International (MSCI) Emerging Markets Index (net) is a free float-adjusted market-capitalization-weighted index that is designed to measure equity market performance of emerging markets. The Index is unmanaged, does not incur fees or expenses, and cannot be invested in directly.

The Morningstar Diversified Emerging Markets Category represents the average annual composite performance of all mutual funds listed in the Diversified Emerging Markets 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.

Lipper Ratings are based on a Fund’s average annual total return.

Ratings and rankings are one measure of performance. Ratings may vary among share classes. Ratings reflect expense limitations in effect during the period, without such limitations returns would be lower. Past performance does not guarantee future results.

Weighted Average Market Capitalization: Market capitalization refers to the total market value of each company’s outstanding shares. The Weighted Average Market Capitalization for a portfolio is calculated as the average market capitalization of the stocks within the portfolio, weighted by the amount of each stock owned. Unweighted Median Market Capitalization: This calculation represents the median market capitalization of the stocks in the portfolio, regardless of the amount of each stock owned. P/E (Price/Earnings) Ratio: This ratio is a measure of valuation. It relates the price of the stock to the earnings per share (EPS) of the company. A stock with a higher P/E ratio would be considered more expensive relative to another stock with a lower P/E. An investor may pay a higher P/E for a stock for several reasons including, but not limited to, an expectation that the company possesses higher returns on invested capital, less economic sensitivity, higher consistency of earnings and/or higher earnings growth potential. EPS (Earnings Per Share) Growth Rate (Projected): This measure represents the weighted average of forecasted growth in earnings expected to be experienced by the stocks within the portfolio over the next 3-5 years. From a portfolio perspective, the portfolio P/E ratio and EPS Growth Rate are weighted averages of the individual holdings’ P/E ratios and EPS Growth Rates. Trailing 1-Year Turnover: This figure reflects the portfolio’s trading activity by calculating the amount of the portfolio’s holdings bought or sold over the prior year, expressed as a percentage of the portfolio’s average market value. Turnover figures may be related to the amount of trading costs experienced by the portfolio. Standard Deviation: A measure of the portfolio’s risk. A higher standard deviation represents a greater dispersion of returns, and thus, a greater amount of risk. Standard deviation returns shown are annualized and calculated using monthly returns. Funds without a 10-year history are reported against the Fund’s inception date. If the Fund’s inception date does not fall on the first day of a given month, the annualized standard deviation is calculated based on the first day of the month following the Fund’s inception date.
