The Fund invests only in securities rated investment grade at the time of purchase by a third-party rating agency or, if unrated, deemed to be of comparable quality. Up to 20% of the Funds net assets may be invested in sectors outside the Funds benchmark index, the Bloomberg World Government 1-10 year Inflation-Linked Bond Index USD hedged (the Index). The Fund seeks to maintain an average duration (a measure of interest rate sensitivity) that is within +/ 20% of the duration of the Index. The Fund generally invests at least 40% of its net assets in debt obligations of foreign governments, and their agencies or instrumentalities. This amount may be reduced to 20% if market conditions for these investments or specific foreign markets are deemed unfavorable. The Fund may invest in derivatives such as futures (including bond and interest rate futures), forward contracts, including forward foreign currency contracts, swaps and options. The Fund may enter into derivatives for investment purposes, for risk management (hedging) purposes, and to increase flexibility. The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The portfolio managers may hedge any portion of the non-U.S. dollar denominated securities in the Fund to the U.S. dollar. The Funds investment strategy may involve the frequent trading of portfolio securities. This may cause the Fund to incur higher transaction costs (which may adversely affect the Funds performance). The Fund may hold cash or cash equivalents in order to shorten the duration of the portfolio or to otherwise implement the Funds investment strategy or for temporary defensive purposes. The Fund is non-diversified for purposes of the Investment Company Act of 1940, and as a result may invest a greater percentage of assets in a particular issuer than a diversified fund. Show less
