Strategy. The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities issued, guaranteed or otherwise backed by the U.S. Government, its agencies, instrumentalities or sponsored corporations (each, a Federal Agency), and in derivatives and other instruments that have economic characteristics similar to such securities.

These securities include: (1) direct obligations of the U.S. Treasury, including bills, notes and bonds, and (2) obligations issued or guaranteed by Federal Agencies and supported by (a) the full faith and credit of the U.S. Treasury, (b) the right of the issuer to borrow from the U.S. Treasury, or (c) the credit of the Federal Agency. The Fund primarily invests in fixed income securities of the following types: callable bonds that can be redeemed by the issuer prior to their stated maturity; bullet-maturity debt bonds with a stated maturity date; mortgage-backed securities (MBS) consisting of interests in underlying mortgages with maturities of up to thirty years; and U.S. Treasury and Federal Agency holdings, including U.S. Treasury Inflation Protected Securities (TIPS). TIPS are publicly issued, dollar denominated U.S. government securities issued by the U.S. Treasury that have principal and interest payments linked to official inflation (as measured by the Consumer Price Index or CPI) and their payments are supported by the full faith and credit of the United States. The Fund may purchase mortgage-backed and asset-backed securities such as collateralized mortgage obligations (CMOs), collateralized loan obligations (CLOs) and collateralized debt obligations (CDOs). The Funds investments may include securities that do not produce immediate cash income, such as zero coupon securities and payment-in-kind securities. Some of the securities that the Fund invests in may be subject to resale restrictions and are exempt from registration under the Securities Act of 1933, as amended (Securities Act), such as those contained in Rule 144A promulgated under the Securities Act. The Fund may purchase and sell securities on a when-issued and delayed delivery basis, which means that the Fund may buy or sell a security with payment and delivery taking place in the future. The Fund may also engage in to be announced (TBA) transactions, which are transactions in which a fund buys or sells mortgage-backed securities on a forward commitment basis. The Fund may engage in short sales of TBA mortgages, including short sales on TBA mortgages the Fund does not own. The Fund can invest in derivative instruments, including swap contracts, options and futures contracts. The Fund can use swap contracts, including interest rate swaps, to hedge or adjust its exposure to interest rates. The Fund can further use volatility swaps and credit default swaps to manage interest rate exposure; and total return swaps to manage interest rate and credit exposures. The Fund can use options, including swaptions (options on swaps), to manage interest rate risk. The Fund can further use options on bond or rate futures to manage interest rate exposure. The Fund can use futures contracts, including interest rate futures contracts, to increase or reduce exposure to changes in interest rates. The Fund can also use futures contracts, including Treasury futures, to gain exposure to the U.S. Treasury and Federal Agency MBS markets while deploying Fund assets in other securities. The portfolio managers utilize the Bloomberg Intermediate U.S. Government Index as a reference in structuring and reviewing the portfolio, but the Fund is not an index fund that seeks to replicate the performance of the index. The portfolio managers decide on appropriate risk factors such as duration, the shape of the U.S. Treasury yield curve, Federal Agency exposure, Federal Agency MBS exposure, and TIPS exposure relative to this index. The portfolio managers then employ proprietary technology to calculate appropriate position sizes for each of these risk factors. In doing so, the portfolio managers consider recommendations from a globally interconnected team of specialist decision makers in positioning the Fund to generate alpha (return on investments in excess of the Bloomberg Intermediate U.S. Government Index). The portfolio managers generally rely upon a team of market-specific specialists for trade execution and for assistance in determining efficient ways (in terms of cost-efficiency and selection) to implement those recommendations. Although a variety of specialists provide input in the management of the Fund, the portfolio managers retain responsibility for ensuring the Fund is positioned appropriately in terms of risk exposures and position sizes. Specialists employ a bottom-up approach to recommending larger or smaller exposure to specific risk factors. In general, specialists will look for attractive risk-reward opportunities and securities that best enable the Fund to pursue those opportunities. The portfolio managers consider the recommendations of these market-specific specialists in adjusting the Funds risk exposures and security selection on a real-time basis using proprietary communication technology. Decisions to purchase or sell securities are determined by the relative value considerations of the investment professionals that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situation-specific opportunities. The purchase or sale of securities may be related to a decision to alter the Funds macro risk exposure (such as duration, yield, curve positioning and sector exposure), a need to limit or reduce the Funds exposure to a particular security or issuer, degradation of an issuers credit quality, or general liquidity needs of the Fund. The Fund invests in securities of all maturities, but will maintain a weighted average effective maturity for the portfolio of between three and ten years. In attempting to meet its investment objective or to manage subscription and redemption requests, the Fund may engage in active and frequent trading of portfolio securities. Show less
