Example.This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those

periods. This Example does not include commissions and/or other forms of compensation that investors may pay on transactions in Class Y and Class R6 shares. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

	1 Year	3 Years	5 Years	10 Years
Class A	$509	$688	$882	$1,441
Class C	$265	$511	$881	$1,718
Class R	$114	$356	$617	$1,363
Class Y	$63	$199	$346	$774
Class R5	$59	$186	$324	$726
Class R6	$52	$164	$285	$640

You would pay the following expenses if you did not redeem your shares:

	1 Year	3 Years	5 Years	10 Years
Class A	$509	$688	$882	$1,441
Class C	$165	$511	$881	$1,718
Class R	$114	$356	$617	$1,363
Class Y	$63	$199	$346	$774
Class R5	$59	$186	$324	$726
Class R6	$52	$164	$285	$640

Portfolio Turnover.The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 427% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in mortgage-backed securities of any maturity or type guaranteed by, or secured by collateral that is guaranteed by, the U.S. government, its agencies, instrumentalities or sponsored corporations (a Federal Agency), and in mortgage-backed securities privately issued in the United States, and in derivatives and other instruments that have economic characteristics similar to such securities.

Mortgage-backed securities generally consist of government mortgage pass-through securities, collateralized mortgage obligations (CMOs), multiclass pass-through securities, private mortgage pass-through securities, stripped mortgage securities and inverse floaters. The Fund historically has invested primarily in mortgage-backed securities that directly or indirectly represent a participation in, or are secured by and payable from, mortgage loans secured by real property. Mortgage-backed securities also include mortgage pass-through certificates representing participation interests in pools of mortgage loans originated by the U.S. government or private lenders and guaranteed by U.S. government agencies such as the Government National Mortgage Association (GNMA), the Federal National Mortgage Association (FNMA) or the Federal Home Loan Mortgage Corporation (FHLMC).

The Fund may invest in real estate mortgage investment conduits (REMICs).

The Fund may invest in stripped mortgage securities, which are derivative multi-class mortgage securities.

The Fund may also invest in asset-backed securities.

The Fund may invest in illiquid or thinly traded securities. The Fund may also invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933. The Fund's investments may include securities that do not produce immediate cash income, such as zero coupon securities and payment-in-kind securities.

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. TBA transactions may be conducted as dollar rolls. The Fund may engage in short sales of TBA mortgages, including short sales of 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 also use swap contracts, including credit default swaps, to create long or short exposure to corporate or sovereign debt securities. The Fund can further use total return swaps to gain exposure to a reference asset, and volatility swaps to adjust the volatility profile of the Fund.

The Fund can use options, including swaptions (options on swaps), to manage interest rate risk and options on bond or rate futures to manage interest rate exposure.

The Fund can use futures contracts, including interest rate futures, to increase or reduce its exposure to interest rate changes.

The Fund utilizes active duration (i.e., making investments to reduce or increase the sensitivity of the Fund's portfolio to interest rate changes) and yield curve positioning (i.e., making investments that allow the Fund to benefit from varying interest rates) for risk management and for generating alpha (return on investments in excess of the Bloomberg U.S. Mortgage-Backed Securities Index).

The portfolio managers utilize the Bloomberg U.S. Mortgage-Backed Securities 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 mortgage-backed security 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 seek to generate alpha.

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. Specialist investment professionals employ both top down and bottom-up analysis in determining whether to recommend larger or smaller exposure to specific risk factors. In general, these specialists will look for what they believe are 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's risk exposures and security selection on a real-time basis using proprietary communication technology. 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.

Decisions to purchase or sell securities are determined by the relative value considerations of the portfolio managers 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's macro risk exposure (such as duration, yield curve positioning and sector exposure), a decision to limit or reduce the Fund's exposure to a particular security or issuer, degradation of an issuer's credit quality or general liquidity needs of the Fund.

In attempting to meet its investment objective or to manage subscription and redemption requests, the Fund engages in active and frequent trading of portfolio securities.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. 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:

Market Risk. The market values of the Fund's investments, and therefore the value of the Fund's shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund's investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, military conflict, acts of terrorism, economic crisis or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund's distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer's financial strength, the market's perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The credit analysis applied to the Fund's debt securities may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.

Changing Fixed Income Market Conditions Risk. Increases in the federal funds and equivalent foreign rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed income markets. As a result, the value of the Fund's investments and share price may decline. Changes in central bank policies could also result in higher than normal redemptions by shareholders, which could potentially increase the Fund's portfolio turnover rate and transaction costs.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities, including collateralized debt obligations and collateralized mortgage obligations, are subject to prepayment or call risk, which is the risk that a borrower's payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. This could result in the Fund reinvesting these early payments at lower interest rates, thereby reducing the Fund's income. Mortgage- and asset-backed securities also are subject to extension risk, which is the risk that an unexpected rise in interest rates could reduce the rate of prepayments, causing the price of the mortgage- and asset-backed securities and the Fund's share price to fall. 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. Privately-issued mortgage-backed securities and asset-backed securities may be less liquid than other types of securities and the Fund may be unable to sell these securities at the time or price it desires. During periods of market stress or high redemptions, the Fund may be forced to sell these securities at significantly reduced prices, resulting in losses. Liquid privately-issued mortgage-backed securities and asset-backed securities can become illiquid during periods of market stress. Privately-issued mortgage-related securities are not subject to the same underwriting requirements as those with government or government-sponsored entity guarantees and, therefore, mortgage loans underlying privately-issued mortgage-related securities may have less favorable collateral, credit risk, liquidity risk or other underwriting characteristics, and wider variances in interest rate, term, size, purpose and borrower characteristics. The Fund may invest in mortgage pools that include subprime mortgages, which are loans made to borrowers with weakened credit histories or with lower capacity to make timely payments on their mortgages. Liquidity risk is even greater for mortgage pools that include subprime mortgages.

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. The higher yields and interest rates on pay-in-kind securities reflect the payment deferral and increased credit risk associated with such instruments and that such investments may represent a higher credit risk than loans that periodically pay interest.

When-Issued, Delayed Delivery and Forward Commitment Risks. When-issued and delayed delivery transactions subject the Fund to market risk because the value or yield of a security at delivery may be more or less than the purchase price or yield generally available when delivery occurs, and counterparty risk because the Fund relies on the buyer or seller, as the case may be, to consummate the transaction. These transactions also have a leveraging effect on the Fund because the Fund commits to purchase securities that it does not have to pay for until a later date, which increases the Fund's overall investment exposure and, as a result, its volatility.

TBA Transactions Risk. TBA transactions involve the risk of loss if the securities received are less favorable than what was anticipated by the Fund when entering into the TBA transaction, or if the counterparty fails to deliver the securities. When the Fund enters into a short sale of a TBA mortgage it does not own, the Fund may have to purchase deliverable mortgages to

settle the short sale at a higher price than anticipated, thereby causing a loss. As there is no limit on how much the price of mortgage securities can increase, the Fund's exposure is unlimited. The Fund may not always be able to purchase mortgage securities to close out the short position at a particular time or at an acceptable price. In addition, taking short positions results in a form of leverage, which could increase the volatility of the Fund's share price.

Dollar Roll Transactions Risk. Dollar roll transactions occur in connection with TBA transactions and involve the risk that the market value of the securities the Fund is required to purchase may decline below the agreed upon purchase price of those securities. Dollar roll transactions add a form of leverage to the Fund's portfolio, which may make the Fund's returns more volatile and increase the risk of loss. In addition, dollar roll transactions may increase the Fund's portfolio turnover, which may result in increased brokerage costs and may lower the Fund's actual return.

U.S. Government Obligations Risk. Obligations of U.S. government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. government, which could affect the Fund's ability to recover should they default. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Liquidity Risk. The Fund may be unable to sell illiquid investments at the time or price it desires and, as a result, could lose its entire investment in such investments. Liquid securities can become illiquid during periods of market stress. If a significant amount of the Fund's securities become illiquid, the Fund may not be able to timely pay redemption proceeds and may need to sell securities at significantly reduced prices.

Derivatives Risk. The value of a derivative instrument depends largely on (and is derived from) the value of an underlying security, currency, commodity, interest rate, index or other asset (each referred to as an underlying asset). In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage and liquidity risks. Counterparty risk is the risk that the counterparty to the derivative contract will default on its obligation to pay the Fund the amount owed or otherwise perform under the derivative contract. Derivatives create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Fund's returns more volatile and increase the risk of loss. Derivative instruments may also be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be harder to value, less tax efficient and subject to changing government regulation that could impact the Fund's ability to use certain derivatives or their cost. Derivatives strategies may not always be successful. For example, derivatives used for hedging or to gain or limit exposure to a particular market segment may not provide the expected benefits, particularly during adverse market conditions.

Rule 144A Securities and Other Exempt Securities Risk. The market for Rule 144A and other securities exempt from certain registration requirements may be less active than the market for publicly-traded securities. Rule 144A and other exempt securities carry the risk that their liquidity may become impaired and the Fund may be unable to dispose of the securities at a desirable time or price.

Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and other governmental actions and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely

impact the Fund, including by adversely impacting the Fund's operations, universe of potential investment options, and return potential.

Active Trading Risk. Active trading of portfolio securities may result in added expenses, a lower return and increased tax liability.

Management Risk. The Fund is actively managed and depends heavily on the Adviser's judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund's portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser's investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Performance Information

The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31.
