Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund

shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.

Principal Investment Strategies

The Fund employs an active management approach, investing mainly in stocks of companies located outside the United States. The Fund is expected to diversify its assets in countries across developed and emerging markets. In selecting stocks, the Fund’s advisors evaluate foreign markets around the world and choose large-, mid-, and small-capitalization companies considered to have above-average growth potential. The Fund has multiple investment advisors, each of which independently selects and maintains a portfolio of common stocks for the Fund.

Principal Risks

As with any investment, an investment in the Fund could lose money over any time period. The Fund’s share price and total return may fluctuate, potentially within a wide range. The principal risks of investing in the Fund are summarized below. Each of the following risks could affect the Fund’s performance:

• General Market Risk. The markets in which the Fund invests can be affected by a variety of factors. These factors, which can be real or perceived, may include economic, market, political, and regulatory conditions and developments as well as local, regional, or global events such as wars, military conflicts, natural disasters, and public health issues. In addition, investor sentiment and expectations regarding these factors can also impact the markets. Different parts of the market, including different industries and sectors as well as different types of securities, may react differently to factors that affect the market. These factors can contribute to market uncertainty, market volatility, and fluctuations in the value of the Fund’s investments, thereby resulting in potential losses to the Fund over short or long periods.

• Investing in Foreign Markets. Foreign markets can perform differently than U.S. markets. World events could adversely affect the value and/or liquidity of securities of foreign companies or foreign issuers, potentially in ways that differ from impacts to U.S. companies or issuers. Further, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region could adversely impact a different country or region. In addition, the rights and remedies associated with investments in a fund that invests in foreign securities may be different than a fund that invests in domestic securities. To the extent that the Fund invests a large portion of its assets in securities of issuers located primarily in one country or region, the Fund’s performance may be hurt disproportionately by the poor performance of its investments in such country or region. 

• Investing in Emerging Markets. Investments in emerging markets are subject to higher degrees of risk and volatility than investments in developed markets. Compared with developed markets, emerging markets can have greater custodial and operational risks; less developed legal, tax, regulatory, financial reporting, accounting, and recordkeeping systems; and greater political, social, and economic instability than developed markets. In addition, emerging markets generally have less efficient trading markets with lower overall liquidity and more volatile currency exchange rates. Each of these risks can cause losses to the Fund’s investments and/or impact the Fund’s performance.

• Currency Risk. The Fund is subject to the risk that foreign currency will perform differently than U.S. dollars and increase the potential loss to the Fund. Currency exchange rates may be volatile, move rapidly, and change as a result of changes in interest rates, inflation rates, government surpluses or deficits, and monetary policy or currency controls imposed by local governments or supranational entities such as the International Monetary Fund. Changes in currency exchange rates can affect the value of the Fund’s holdings.

• Investments Economically Tied to China. The risks described under Investing in Foreign Markets, Investing in Emerging Markets, and Currency Risk apply to, and may be heightened with respect to, the Fund’s investments in companies or issuers economically tied to China. The Fund also is subject to unique risks due to the considerable degrees of social and humanitarian, legal, regulatory, political, and economic uncertainty associated with investments in companies or issuers economically tied to China. All of these factors, among others, could have negative impacts on the Fund. For example, the Fund may not be able to access its desired amount of shares of companies incorporated in China that trade on the Shanghai and Shenzhen Stock Exchanges (A-shares) and/or the Hong Kong Stock Exchange (H-shares), which may cause the Fund to miss out on investment opportunities. Investments economically tied to China may be (or become in the future) restricted or sanctioned by the U.S. government, which could cause these securities to decline in value or become less liquid. If the Fund’s holdings become impacted by restrictions or sanctions, the Fund may incur losses. Additionally, the Fund may gain exposure to certain companies in China through legal structures known as variable interest entities (VIEs), which provide exposure to Chinese companies through contractual arrangements instead of equity ownership. Investing through a VIE does not offer the same level of investor protection as direct ownership and is subject to risks including breach of the contractual arrangements, difficulty in enforcing the contractual arrangements outside of the United States, and intervention by the U.S. government. These risks could significantly affect a VIE’s market value, which in turn could impact the Fund’s performance.

• Investing in Equity Markets. The Fund invests in the equity markets. Equity markets have historically been cyclical, having periods of time when stock values rise and fall. Market volatility can lead to significant fluctuations in stock values, resulting in potential losses to the Fund.

• Market Capitalization (Market Cap). Companies are generally classified into three types of market cap depending on their size: small-, mid-, and large-cap. Companies can be further classified into micro- or mega-cap. Different factors can affect each market cap uniquely, and historically small- and mid-cap stocks have typically been more volatile due to the effects of changing economic conditions. Large companies may not reach the same levels of growth or performance as smaller companies, and they may be slower to react to competitive challenges. The performance of funds that invest in a subset of market caps could diverge from the performance of a fund that is focused on a broader representation of the stock market.

• Growth Investing. The Fund’s approach to growth investing could cause it to underperform other stock funds that use a different investment style. Growth stocks typically produce lower yields because growth companies prefer to reinvest earnings into research and development to promote growth and increase profitability. Research and development can be expensive and may not always produce favorable results, which could harm a company’s performance relative to the broader market.

• Active Management. The Fund is actively managed. The advisors’ security selection and/or strategy execution could cause the Fund to underperform relevant securities markets or other funds with a similar investment objective.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are shown only for the Investor Shares and may differ for each share class. After-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares may be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.
