Examples. The following examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The examples assume that you invest $10,000 in a class of shares of the Fund for the time periods indicated.  The examples also assume 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 expenses would be as follows:

	If shares are redeemed											If shares are not redeemed
	1 Year		3 Years			5 Years			10 Years			1 Year		3 Years		5 Years		10 Years
Class A	$	563		$	750		$	952		$	1,535	$	563	$	750	$	952		$	1,535
Class B	$	669		$	825		$	1,104		$	1,582	$	169	$	525	$	904		$	1,582
Class C	$	269		$	525		$	904		$	1,970	$	169	$	525	$	904		$	1,970
Class N	$	218		$	367		$	637		$	1,405	$	118	$	367	$	637		$	1,405
Class Y	$	67		$	209		$	363		$	813	$	67	$	209	$	363		$	813

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 the annual fund operating expenses or in the examples, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 109% of the average value of its portfolio.

Principal Investment Strategies. The Fund mainly invests in debt securities issued or guaranteed by the U.S. Treasury or by other agencies or entities of the U.S. government, referred to as "instrumentalities." Debt securities are securities representing money borrowed by the issuer that must be repaid, specifying the amount of principal, the interest or discount rate, and the time or times at which payments are due.

• Under normal market conditions, the Fund will invest at least 80% of its net assets, plus borrowings for investment purposes, in U.S. government securities.

• The Fund typically invests a substantial portion of its assets in mortgage-related U.S. government securities, including collateralized mortgage obligations (called CMOs), mortgage participation certificates and forward rolls.

• The Fund may also invest up to 20% of its net assets in securities issued by private entities, including mortgage-related securities that do not have any government guarantees.

The Fund's portfolio managers weigh yields and relative values against risks and they currently focus on securities that have high relative income potential. The Fund may invest in debt securities that pay interest at fixed, floating or variable rates and can buy securities of any maturity. When the average maturity of the Fund's portfolio is longer, its share prices may fluctuate more when interest rates change. The Fund limits its investments in private issuer securities to investment-grade securities but it is not required to dispose of a debt security if its rating falls after the Fund buys it.

The Fund may use derivative instruments, including futures, CMOs, and total return swaps to try to enhance income and manage investment risks. The prices of derivative securities may be more volatile than the prices of other types of securities.

The Fund's share prices and distributions are not backed or guaranteed by the U.S. government.

Principal Risks. The price of the Fund's shares can go up and down substantially. The value of the Fund's investments may change because of broad changes in the markets in which the Fund invests or from poor security selection, which could cause the Fund to underperform other funds with similar objectives. There is no assurance that the Fund will achieve its investment objective. When you redeem your shares, they may be worth more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.

Risks of Debt Securities. Debt securities may be subject to credit risk, interest rate risk, prepayment risk and extension risk. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund's income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer's credit rating, for any reason, can also reduce the market value of the issuer's securities. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and may be worth less than the amount the Fund paid for them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. When interest rates fall, the issuers of debt securities may prepay principal more quickly than expected and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as "prepayment risk." When interest rates rise, debt securities may be repaid more slowly than expected and the value of the Fund's holdings may fall sharply. This is referred to as "extension risk." Interest rate changes normally have different effects on variable or floating rate securities than they do on securities with fixed interest rates.

Although most of the securities that the Fund invests in are issued or guaranteed by the U.S. Government or its agencies or instrumentalities, the Fund also invests in securities issued by private issuers, which do not have any government guarantees. While the Fund's investments in U.S. Government securities may be subject to little credit risk, the Fund's other investments in debt securities are subject to risks of default.

     Fixed-Income Market Risks. Recently, developments relating to subprime mortgages have adversely affected fixed-income securities markets in the United States, Europe and elsewhere. The values of many types of debt securities have been reduced, including debt securities that are not related to mortgage loans. These developments have reduced the willingness of some lenders to extend credit and have made it more difficult for borrowers to obtain financing on attractive terms or at all. In addition, broker-dealers and other market participants have been less willing to make a market in some types of debt instruments, which has impacted the liquidity of those instruments. These developments also have had a negative effect on the broader economy. There is a risk that the lack of liquidity or other adverse credit market conditions may hamper the Fund's ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

        Special Risks of Lower-Grade Securities. Lower-grade securities may be subject to wider market fluctuations and greater risk of loss of income and principal than investment-grade securities. While investment-grade securities are subject to risks of non-payment of interest and principal, in general those risks are greater for higher-yielding lower-grade bonds, whether rated or unrated. The market for lower-grade securities may be less liquid and therefore they may be harder to sell at an acceptable price, especially during times of market volatility or decline.

Risks of Derivative Investments. Derivatives may be volatile and may involve significant risks. The underlying security or other instrument on which a derivative is based, or the derivative itself, may not perform as expected. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund's initial investment. The Fund may also lose money on a derivative investment if the issuer fails to pay the amount due. Certain derivative investments held by the Fund may be illiquid, making it difficult to close out an unfavorable position. Derivative transactions may require the payment of premiums and can increase portfolio turnover. As a result of these risks, the Fund could realize little or no income or lose money from its investment, or a hedge might be unsuccessful.

Who Is the Fund Designed For? The Fund is designed primarily for investors seeking current income from a fund that invests mainly in U.S. government securities but also buys private-issuer mortgage-related securities. The Fund is intended to be a long-term investment, not a short-term trading vehicle. Because the Fund's income will fluctuate, it is not designed for investors needing an assured level of current income. The Fund is not a complete investment program. You should carefully consider your own investment goals and risk tolerance before investing in the Fund.

An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The Fund's Past Performance.
