There is no assurance that a mutual fund will achieve its investment objective. Funds are subject to market risk, which is the possibility that the market values of securities owned by the fund will decline and that the value of fund shares may therefore be less than what you paid for them. Accordingly, you can lose money investing in this fund. Please be aware that this fund may be subject to certain additional risks. Foreign and emerging markets. Investments in foreign markets entail special risks such as currency, political, economic, and market risks. The risks of investing in emerging market countries are greater than the risks generally associated with foreign investments. REITs. The risks associated with ownership of real estate and the real estate industry in general include fluctuations in the value of underlying property, defaults by borrowers or tenants, market saturation, decreases in market rents, interest rates, property taxes, increases in operating expenses and political or regulatory occurrences adversely affecting real estate. Derivative instruments. Derivatives are subject to counterparty risk, can be illiquid, may disproportionately increase losses and may have a potentially large negative impact on the fund's performance. Investments in other investment companies, including ETFs, are commonly used when direct investments in certain countries are not permitted by foreign investors. Investments in other investment companies, including ETFs, may involve duplication of management fees and certain other expenses. Small- and mid-cap stocks. Stocks of small- and medium-sized companies entail special risks, such as limited product lines, markets, and financial resources, and greater market volatility than securities of larger, more-established companies.
