Although the fund&lt;br /&gt;seeks to preserve the value of your investment at $1.00 per share, it is&lt;br /&gt;possible to lose money by investing in the fund.&lt;br /&gt; &lt;br /&gt;The fund&apos;s yield will fluctuate as the short-term securities in its portfolio&lt;br /&gt;mature and the proceeds are reinvested in securities with different interest&lt;br /&gt;rates. Additionally, while the fund has maintained a constant share price since&lt;br /&gt;inception, and will continue to try to do so, neither The Dreyfus Corporation&lt;br /&gt;nor its affiliates are required to make a capital infusion, enter into a capital &lt;br /&gt;support agreement or take other actions to prevent the fund&apos;s share price from &lt;br /&gt;falling below $1.00. The following are the principal risks that could reduce &lt;br /&gt;the fund&apos;s income level and/or share price:&lt;br /&gt; &lt;br /&gt;o Interest rate risk. This risk refers to the decline in the prices of&lt;br /&gt;fixed-income securities that may accompany a rise in the overall level of&lt;br /&gt;interest rates. A sharp and unexpected rise in interest rates could cause a&lt;br /&gt;money market fund&apos;s share price to drop below a dollar.&lt;br /&gt; &lt;br /&gt;o Credit risk. Failure of an issuer to make timely interest or principal&lt;br /&gt;payments, or a decline or perception of a decline in the credit quality of a&lt;br /&gt;security, can cause the security&apos;s price to fall, potentially lowering the&lt;br /&gt;fund&apos;s share price. Although the fund invests only in high quality debt&lt;br /&gt;securities, any of the fund&apos;s holdings could have its credit rating downgraded&lt;br /&gt;or could default. The credit quality of the securities held by the fund can&lt;br /&gt;change rapidly in certain market environments, and the default of a single&lt;br /&gt;holding could have the potential to cause significant deterioration of the&lt;br /&gt;fund&apos;s net asset value.&lt;br /&gt; &lt;br /&gt;o Liquidity risk. When there is little or no active trading market for specific&lt;br /&gt;types of securities, it can become more difficult to sell the securities at or&lt;br /&gt;near their perceived value. In such a market, the value of such securities may&lt;br /&gt;fall dramatically, potentially lowering the fund&apos;s share price, even during&lt;br /&gt;periods of declining interest rates. Also, during such periods, redemptions by a&lt;br /&gt;few large investors in the fund may have a significant adverse effect on the&lt;br /&gt;fund&apos;s net asset value and remaining fund shareholders.&lt;br /&gt; &lt;br /&gt;o State-specific risk. The fund is subject to the risk that New York&apos;s economy,&lt;br /&gt;and the revenues underlying its municipal obligations, may decline. Investing&lt;br /&gt;primarily in a single state makes the fund more sensitive to risks specific to&lt;br /&gt;the state and may magnify other risks.&lt;br /&gt; &lt;br /&gt;o Tax risk. To be tax-exempt, municipal obligations generally must meet certain&lt;br /&gt;regulatory requirements. If any such municipal obligation fails to meet these&lt;br /&gt;regulatory requirements, the interest received by the fund from its investment&lt;br /&gt;in such obligations and distributed to fund shareholders will be taxable.&lt;br /&gt; &lt;br /&gt;o Structured notes risk. Structured notes, a type of derivative instrument, can&lt;br /&gt;be volatile, and the possibility of default by the financial institution or&lt;br /&gt;counterparty may be greater for these instruments than for other types of money&lt;br /&gt;market instruments. Structured notes typically are purchased in privately&lt;br /&gt;negotiated transactions from financial institutions and, thus, an active trading&lt;br /&gt;market for such instruments may not exist.&lt;br /&gt; &lt;br /&gt;o Non-diversification risk. The fund is non-diversified, which means that a&lt;br /&gt;relatively high percentage of the fund&apos;s assets may be invested in a limited&lt;br /&gt;number of issuers. Therefore, the fund&apos;s performance may be more vulnerable to&lt;br /&gt;changes in the market value of a single issuer or group of issuers and more&lt;br /&gt;susceptible to risks associated with a single economic, political or regulatory&lt;br /&gt;occurrence than a diversified fund.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

The fund invests at least 80% of its&lt;br /&gt;assets in municipal bonds rated investment grade (Baa/BBB or higher) or the&lt;br /&gt;unrated equivalent as determined by The Dreyfus Corporation. For additional&lt;br /&gt;yield, the fund may invest up to 20% of its assets in municipal bonds rated&lt;br /&gt;below investment grade ("high yield" or "junk" bonds) or the unrated equivalent&lt;br /&gt;as determined by The Dreyfus Corporation. The dollar-weighted average maturity&lt;br /&gt;of the fund&apos;s portfolio normally exceeds ten years, but the fund may invest&lt;br /&gt;without regard to maturity.&lt;br /&gt; &lt;br /&gt;The portfolio managers focus on identifying undervalued sectors and securities.&lt;br /&gt;To select municipal bonds for the fund, the portfolio managers use fundamental&lt;br /&gt;credit analysis to estimate the relative value and attractiveness of various&lt;br /&gt;sectors and securities and actively trade among various sectors, based on their&lt;br /&gt;apparent relative values.&lt;br /&gt; &lt;br /&gt;Although the fund seeks to provide income exempt from federal, New York state&lt;br /&gt;and New York city income taxes, income from some of the fund&apos;s holdings may be&lt;br /&gt;subject to the federal alternative minimum tax. In addition, the fund may invest&lt;br /&gt;temporarily in taxable obligations.&lt;/tt&gt;</rr:StrategyNarrativeTextBlock>

It is not insured or guaranteed&lt;br /&gt;by the Federal Deposit Insurance Corporation (FDIC) or any other government&lt;br /&gt;agency. It is not a complete investment program. The fund&apos;s share price&lt;br /&gt;fluctuates, sometimes dramatically, which means you could lose money.&lt;br /&gt; &lt;br /&gt;o Municipal bond market risk. The amount of public information available about&lt;br /&gt;municipal bonds is generally less than that for corporate equities or bonds.&lt;br /&gt;Special factors, such as legislative changes, and state and local economic and&lt;br /&gt;business developments, may adversely affect the yield and/or value of the fund&apos;s&lt;br /&gt;investments in municipal bonds. Other factors include the general conditions of&lt;br /&gt;the municipal bond market, the size of the particular offering, the maturity of&lt;br /&gt;the obligation and the rating of the issue. Changes in economic, business or&lt;br /&gt;political conditions relating to a particular municipal project, municipality,&lt;br /&gt;or state in which the fund invests may have an impact on the fund&apos;s share price.&lt;br /&gt; &lt;br /&gt;o Interest rate risk. Prices of municipal bonds tend to move inversely with&lt;br /&gt;changes in interest rates. Typically, a rise in rates will adversely affect bond&lt;br /&gt;prices and, accordingly, the fund&apos;s share price. The longer the effective&lt;br /&gt;maturity and duration of the fund&apos;s portfolio, the more the fund&apos;s share price&lt;br /&gt;is likely to react to interest rates.&lt;br /&gt; &lt;br /&gt;o Credit risk. Failure of an issuer to make timely interest or principal&lt;br /&gt;payments, or a decline or perception of a decline in the credit quality of a&lt;br /&gt;municipal bond, can cause the bond&apos;s price to fall, potentially lowering the&lt;br /&gt;fund&apos;s share price. The lower a bond&apos;s credit rating, the greater the chance -&lt;br /&gt;in the rating agency&apos;s opinion - that the bond issuer will default or fail to&lt;br /&gt;meet its payment obligations. To the extent the fund invests in high yield&lt;br /&gt;("junk") bonds, its portfolio is subject to heightened credit risk.&lt;br /&gt; &lt;br /&gt;o Liquidity risk. When there is little or no active trading market for specific&lt;br /&gt;types of securities, it can become more difficult to sell the securities at or&lt;br /&gt;near their perceived value. In such a market, the value of such securities and&lt;br /&gt;the fund&apos;s share price may fall dramatically, even during periods of declining&lt;br /&gt;interest rates. The secondary market for certain municipal bonds tends to be&lt;br /&gt;less well developed or liquid than many other securities markets, which may&lt;br /&gt;adversely affect the fund&apos;s ability to sell such municipal bonds at attractive&lt;br /&gt;prices.&lt;br /&gt; &lt;br /&gt;o State-specific risk. The fund is subject to the risk that New York&apos;s economy,&lt;br /&gt;and the revenues underlying its municipal obligations, may decline. Investing&lt;br /&gt;primarily in a single state makes the fund more sensitive to risks specific to&lt;br /&gt;the state and may magnify other risks.&lt;br /&gt; &lt;br /&gt;o Non-diversification risk. The fund is non-diversified, meaning that a&lt;br /&gt;relatively high percentage of the fund&apos;s assets may be invested in a limited&lt;br /&gt;number of issuers. Therefore, the fund&apos;s performance may be more vulnerable to&lt;br /&gt;changes in the market value of a single issuer or group of issuers and more&lt;br /&gt;susceptible to risks associated with a single economic, political or regulatory&lt;br /&gt;occurrence than a diversified fund.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>
