Investing involves risk, including possible loss of principal.

Asset allocation and diversification do not ensure a profit or protect against a loss.

Real estate investment options are subject to some risks inherent in real estate and Real Estate Investment Trusts, such as risks associated with general and local economic conditions.

Fixed-income investment options (inclusive of U.S. Treasury Inflation-Protected Securities) are subject to interest rate risk, and their value will decline as interest rates rise. Neither the principal of the bond investment options nor their yields are guaranteed by the U.S. government or any other government entity.

Equity investment options involve greater risk, including heightened volatility, than fixed-income investment options. Fixed-income investment options are subject to interest rate risk, and their value will decline as interest rates rise.

Small-cap and mid-cap investment options are subject to more fluctuation in value and may have additional risks than other investment options with stocks of larger, more stable companies.

High yield investment options are subject to greater credit risk associated with high yield bonds.

International and global investment options are subject to additional risk due to fluctuating exchange rates, foreign accounting and financial policies, and other economic and political environments.

Concentrating investments in natural resources industries can be affected significantly by events relating to those industries, such as variations in the commodities markets, weather, disease, embargoes, international, political and economic developments, the success of exploration projects, tax and other government regulations and other factors.

REIT securities are subject to risk factors associated with the real estate industry and tax factors of REIT registration.

Global infrastructure companies may be subject to additional risk due to fluctuating exchange rates, foreign accounting and financial policies, and other economic and political environments.

Commodity-Related Investment Risk: The value of commodities investments will generally be affected by overall market movements and factors specific to a particular industry or commodity, which may include weather, embargoes, tariffs, and economic health, political, international regulatory and other developments. Exposure to the commodities markets may subject the fund to greater volatility than investments in traditional securities.

There is a risk of substantial loss associated with trading commodities, futures, options, derivatives and other financial instruments. Before trading, investors should carefully consider their financial position and risk tolerance to determine if the proposed trading style is appropriate. Investors should realize that when trading futures, commodities, options, derivatives and other financial instruments one could lose the full balance of their account. It is also possible to lose more than the initial deposit when trading derivatives or using leverage. All funds committed to such a trading strategy should be purely risk capital.

Commodity Index-Linked Notes Risk: The value of commodities may be affected by overall market movements and other factors affecting the value of a particular industry or commodity. These notes expose the fund to movements in commodity prices. They are also subject to credit, counterparty, and interest rate risk. Commodity index-linked notes are often leveraged. At the maturity of the note, the fund may receive more or less principal than it originally invested. The fund may also receive interest payments on the note that are less than the stated coupon interest payments.
