Strategy. The Fund seeks to achieve its goal by investing under normal circumstances in commodity-linked derivative instruments and fixed income instruments. Commodities are assets such as oil, natural gas, agricultural products or metals. The Fund seeks to gain long and short exposure to the commodity markets by investing, directly or indirectly, in futures contracts on individual commodities and other commodity-linked derivative instruments. The performance of these commodity-linked derivative instruments is expected to correspond to the performance of the commodity underlying the derivative instrument, without requiring the Fund to invest directly in commodities.

Commodities are assets such as oil, natural gas, agricultural products or metals. The Fund seeks to gain long and short exposure to the commodity markets by investing, directly or indirectly, in futures contracts on individual commodities and other commodity-linked derivative instruments. The performance of these commodity-linked derivative instruments is expected to correspond to the performance of the commodity underlying the derivative instrument, without requiring the Fund to invest directly in commodities. Although the Fund may make these investments in commodity-linked derivative instruments directly, the Fund expects to gain exposure to these investments primarily by investing in a wholly owned subsidiary of the Fund formed in the Cayman Islands (Subsidiary). The Subsidiary is managed by Neuberger Berman Investment Advisers LLC and has the same investment goal as the Fund. The Subsidiary may invest without limitation in commodity-linked derivative instruments. The Subsidiary also may invest in fixed income securities, cash or cash equivalent instruments, or money market mutual funds, some of which may serve as collateral for the Subsidiarys derivative instruments. The Fund will not invest more than 25% of the value of its total assets in the Subsidiary at the end of any quarter of its taxable year. In managing the Funds commodity investments, the Portfolio Managers seek to identify investment opportunities using quantitative investment models and fundamental analyses with an emphasis on risk management in an attempt to take advantage of both short-term and long-term opportunities in commodity markets. By managing a broadly diversified portfolio of commodity investments with an active investment approach, the Portfolio Managers seek to provide investors with an investment vehicle whose returns are not highly correlated with other major asset classes. The Fund may take short positions in commodities. These shorts, bought as derivatives, either anticipate price declines or serve as hedging strategies for risk management. The Portfolio Managers will use various quantitative models employing strategies intended to identify investment opportunities and determine portfolio weightings in different commodity sectors and markets. These strategies include: (i) a risk-balancing strategy that considers the total portfolio risk the Portfolio Managers believe to be associated with each commodity; (ii) a strategy that endeavors to assess top down macro variables among various commodity sectors (such as, energy, industrial, metals, including industrial and strategic metals (e.g., uranium) and precious metals, agricultural, livestock and softs (e.g., sugar, cotton, cocoa and coffee)); and/or (iii) a strategy that endeavors to assess the outlook for individual commodities within each commodity sector. From time to time, the Funds investment program may emphasize a particular sector of the commodities markets. If the Fund emphasizes one or more sectors the performance of your investment in the Fund will likely be affected by events affecting the performance of those sectors. Additional information about certain risks related to the various commodities market sectors are summarized under Additional Information about Principal Investment Risks in the Prospectus. The Funds fixed income investments will be primarily in investment grade fixed income securities and are intended to provide liquidity and preserve capital and may serve as collateral for the Funds derivative instruments. These may include fixed income securities issued by the U.S. government and its agencies and instrumentalities, mortgage-backed securities, asset-backed securities, and securities issued by corporations or trust entities as well as floating rate securities. The Fund considers fixed income securities to be investment grade if, at the time of investment, they are rated within the four highest categories by at least one independent credit rating agency or, if unrated, are determined by the Portfolio Managers to be of comparable quality. The Fund also aims to keep the duration of the fixed income portfolio short. The Fund may invest in cash or cash equivalent instruments. Because the Fund will use derivatives to gain exposure to commodities, and because derivatives may not require the Fund to deposit the full notional amount of the investment, the Fund may invest a significant amount of its assets in money market mutual funds or other fixed income investments, as described above. In relation to this Fund, notional refers to the total value of the Funds aggregate positions. The Funds (and the Subsidiarys) use of commodity-linked derivative instruments to obtain long and short exposure to the commodity markets may result in leverage, which amplifies the risks that are associated with the commodities underlying the derivative instruments. The Funds aggregate investment exposure, as measured on a notional basis, may be greater than 100% of the Funds total assets from time to time. Although the Fund invests primarily in domestic securities and other instruments, it may also invest in foreign securities and other foreign instruments, which may be denominated in any currency. In an effort to achieve its goal, the Fund may engage in active and frequent trading. Show less
