Effective December 14, 2011, the following information is added underneath the last risk appearing under the heading “Fund Summary — Principal Risks of Investing in the Fund”: “Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability. Financial Institutions Risk. Investments in financial institutions may be subject to certain risks, including, but not limited to, the risk of regulatory actions, changes in interest rates and concentration of loan portfolios in an industry or sector. Financial institutions are highly regulated and may suffer setbacks should regulatory rules and interpretations under which they operate change. Likewise, there is a high level of competition among financial institutions which could adversely affect the viability of an institution. Forward Currency Exchange Contracts. An underlying fund may enter into contracts with banks, brokers or dealers to purchase or sell foreign currencies at a future date (forward contracts). A forward currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward currency contracts are used to protect against uncertainty in the level of future currency exchange rates or to gain or modify exposure to a particular currency. An underlying fund will use these contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated. These strategies are implemented within the risk profile of the guidelines set forth in the prospectus. Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns. Preferred Securities Risk. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If an underlying fund owns a security that is deferring or omitting its distributions, an underlying fund may be required to report the distribution on its tax returns, even though it may not have received this income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments. REIT/Real Estate Risk. Investments in real-estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to and underlying fund's holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes. Tax Risk. If the U.S. Treasury Department were to exercise its authority to issue regulations that exclude from the definition of “qualifying income” foreign currency gains not directly related to the Fund's business of investing in securities, the Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Fund's Board of Trustees (Board) may authorize a significant change in investment strategy or Fund liquidation.”
