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.<br /><br />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 Fund&#8217;s investments may include securities that do not produce immediate cash income, such as zero coupon securities and payment-in-kind securities.<br /><br />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 &#8220;to be announced&#8221; (TBA) transactions, which are transactions in which a fund buys or sells mortgage-backed securities on a forward commitment basis.<br /><br />The Fund can invest in derivative instruments including futures contracts.<br /><br />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.<br /><br />The portfolio managers utilize the Barclays US Government Index as a reference in structuring the portfolio. 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 Treasury Inflation-Protected Security (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 Barclays US Government Index).<br /><br />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.<br /><br/>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 Fund&#8217;s risk exposures and security selection on a real-time basis using proprietary communication technology.<br /><br />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 Fund&#8217;s macro risk exposure (such as duration, yield curve positioning and sector exposure), a need to limit or reduce the Fund&#8217;s exposure to a particular security or issuer, degradation of an issuer&#8217;s credit quality, or general liquidity needs of the Fund.<br /><br />The Fund invests in securities of all maturities, but will maintain a weighted average effective maturity for the portfolio of between three and 10 years.<br /><br />In attempting to meet its investment objective, the Fund engages in active and frequent trading of portfolio securities.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: <br /><br />Active Trading Risk. The Fund engages in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.<br /><br/>Collateralized Loan Obligations Risk. In addition to the normal interest rate, default and other risks of fixed income securities, collateralized loan obligations carry additional risks, including the possibility that distributions from collateral securities will not be adequate to make interest or other payments, the quality of the collateral may decline in value or default, the Fund may invest in collateralized loan obligations that are subordinate to other classes, values may be volatile, and disputes with the issuer may produce unexpected investment results.<br /><br />Credit Risk. The issuer of instruments in which the Fund invests may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer&#8217;s credit rating.<br /><br />Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index, commodity or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the Adviser elects not to do so due to availability, cost, market conditions or other factors.<br /><br />Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration.<br /><br />Management Risk. The investment techniques and risk analysis used by the Fund&#8217;s portfolio managers may not produce the desired results.<br /><br />Market Risk. The prices of and the income generated by the Fund&#8217;s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.<br /><br />Mortgage- and Asset-Backed Securities Risk. The Fund may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower&#8217;s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, the Fund may reinvest these early payments at lower interest rates, thereby reducing the Fund&#8217;s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of mortgage-backed securities and could result in losses to the Fund. The risk of such defaults is generally higher in the case of mortgage pools that include subprime mortgages. Subprime mortgages refer to loans made to borrowers with weakened credit histories or with lower capacity to make timely payments on their mortgages.<br /><br />Reinvestment Risk. Reinvestment risk is the risk that a bond&#8217;s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond.<br /><br />TBA Transactions Risk. TBA transactions involve the risk that the securities received may be less favorable than what was anticipated by the Fund when entering into the TBA transaction. TBA transactions also involve the risk that a counterparty will fail to deliver the securities, exposing the Fund to further losses. Whether or not the Fund takes delivery of the securities at the termination date of a TBA transaction, the Fund will nonetheless be exposed to changes in the value of the underlying investments during the term of the agreement.<br /><br />U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund&#8217;s ability to recover should they default.<br /><br />When-Issued and Delayed Delivery Risks. When-issued and delayed delivery transactions are subject to market risk as the value or yield of a security at delivery may be more or less than the purchase price or the yield generally available on securities when delivery occurs. In addition, the Fund is subject to counterparty risk because it relies on the buyer or seller, as the case may be, to consummate the transaction, and failure by the other party to complete the transaction may result in the Fund missing the opportunity of obtaining a price or yield considered to be advantageous.<br /><br />Zero Coupon or Pay-In-Kind Securities Risk. The value, interest rates, and liquidity of non-cash paying instruments, such as zero coupon and pay-in-kind securities, are subject to greater fluctuation than other types of securities.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.
