FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;">The fund seeks as high a level of current income as is consistent with the preservation of capital and the maintenance of liquidity. </font></p>Principal Investment Strategy<p style="TEXT-ALIGN: left"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;">To pursue its goal, the fund normally invests in a diversified portfolio of high quality, short-term, dollar-denominated debt securities, including: securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities; certificates of deposit, time deposits, bankers' acceptances and other short-term securities issued by domestic or foreign banks or thrifts or their subsidiaries or branches; repurchase agreements, including tri-party repurchase agreements; asset-backed securities; municipal securities; domestic and dollar-denominated foreign commercial paper and other short-term corporate obligations, including those with floating or variable rates of interest; and dollar-denominated obligations issued or guaranteed by one or more foreign governments or any of their political subdivisions or agencies.</font></p> <br/><p style="TEXT-ALIGN: left"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;">The fund's investments are concentrated in the banking industry, because the fund normally invests at least 25% of its net assets in domestic or dollar-denominated foreign bank obligations. </font></p> <br/><p style="TEXT-ALIGN: left"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;">The fund is a money market fund subject to the maturity, quality, liquidity and diversification requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended, although the net asset value (NAV) of the fund's shares will "float," meaning the NAV will fluctuate with changes in the values of the fund's portfolio securities.</font></p>Example<p style="TEXT-ALIGN: left"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;">The 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 hold or redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same.

A sharp and unexpected rise in interest rates could cause the fund's share price to decline. A low interest rate environment may prevent the fund from providing a positive yield or paying fund expenses out of fund assets and could lead to a decline in the fund's share price.</font></p> <br/><p style="TEXT-ALIGN: left; MARGIN-LEFT: 9.35pt; TEXT-INDENT: -9.35pt"><font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; font-family: symbol;">·</font></font><font><font style="WORD-SPACING: 10pt"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; font-family: symbol;"> </font></font></font><font><i><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal">Liquidity risk</font></i></font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal">. When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities in a timely manner at or near their perceived value. In such a market, the value of such securities may fall dramatically, potentially leading to a decline in the fund's share price, even during periods of declining interest rates. </font></p> <br/><p style="TEXT-ALIGN: left; MARGIN-LEFT: 8.65pt; TEXT-INDENT: -8.65pt"><font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;">·</font></font><font><font style="WORD-SPACING: 10pt"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;"> </font></font></font><font><i><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; color: #000000;">Credit risk.</font></i></font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;"> Failure of an issuer of a security to make timely interest or principal payments when due, or a decline or perception of a decline in the credit quality of a security, can cause the security's price to fall. Although the fund invests only in high quality debt securities, the credit quality of the securities held by the fund can change rapidly in certain market environments, and the default or a significant price decline of a single holding could have the potential to cause significant deterioration of the fund's NAV. </font></p> <br/><p style="TEXT-ALIGN: left; MARGIN-LEFT: 8.65pt; TEXT-INDENT: -8.65pt"><font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;">·</font></font><font><font style="WORD-SPACING: 10pt"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;"> </font></font></font><font><i><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; color: #000000;">Floating NAV risk</font></i></font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;">. The fund does not maintain a stable NAV per share. The NAV of the fund's shares will be calculated to four decimal places and will "float," meaning the NAV will fluctuate with changes in the values of the fund's portfolio securities. You could lose money by investing in the fund.</font></p> <br/><p style="TEXT-ALIGN: left; MARGIN-LEFT: 8.65pt; TEXT-INDENT: -8.65pt"><font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;">·</font></font><font><font style="WORD-SPACING: 10pt"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;"> </font></font></font><font><i><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; color: #000000;">Liquidity fee and/or redemption gate risk.</font></i></font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;"> The fund may impose a fee upon the sale of your shares (a "liquidity fee") or may temporarily suspend your ability to sell shares (a redemption "gate") if the fund's liquidity falls below required minimums because of unusual market conditions, an unusually high volume of redemption requests, redemptions by a few large investors, or other reasons. If a liquidity fee is imposed by the fund, it would reduce the amount you will receive upon the redemption of your shares. A "gate" will suspend your ability to redeem your shares while the gate is imposed and may prevent the fund from being able to pay redemption proceeds within the allowable time period stated in this prospectus.</font></p> <br/><p style="TEXT-ALIGN: left; MARGIN-LEFT: 8.65pt; TEXT-INDENT: -8.65pt"><font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;">·</font></font><font><font style="WORD-SPACING: 10pt"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;"> </font></font></font><font><i><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; color: #000000;">Banking industry risk. </font></i></font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;">The risks generally associated with concentrating investments in the banking industry include interest rate risk, credit risk, and regulatory developments relating to the banking industry. </font></p> <br/><p style="TEXT-ALIGN: left; MARGIN-LEFT: 8.65pt; TEXT-INDENT: -8.65pt"><font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;">·</font></font><font><font style="WORD-SPACING: 10pt"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;"> </font></font></font><font><i><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; color: #000000;">Foreign investment risk.</font></i></font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;"> The risks generally associated with dollar-denominated foreign investments include economic and political developments, seizure or nationalization of deposits, imposition of taxes or other restrictions on payment of principal and interest.</font></p> <br/><p style="TEXT-ALIGN: left; MARGIN-LEFT: 8.65pt; TEXT-INDENT: -8.65pt"><font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;">·</font></font><font><font style="WORD-SPACING: 10pt"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;"> </font></font></font><font><i><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; color: #000000;">U.S. Treasury securities risk.</font></i></font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;"> A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate.</font></p> <br/><p style="TEXT-ALIGN: left; MARGIN-LEFT: 8.65pt; TEXT-INDENT: -8.65pt"><font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;">·</font></font><font><font style="WORD-SPACING: 10pt"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;"> </font></font></font><font><i><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; color: #000000;">Government securities risk.</font></i></font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;"> Not all obligations of the U.S. government, its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury.

Although the fund invests only in high quality debt securities, the credit quality of the securities held by the fund can change rapidly in certain market environments, and the default or a significant price decline of a single holding could have the potential to cause significant deterioration of the fund's NAV. </font></p> <br/><p style="TEXT-ALIGN: left; MARGIN-LEFT: 8.65pt; TEXT-INDENT: -8.65pt"><font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;">·</font></font><font><font style="WORD-SPACING: 10pt"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;"> </font></font></font><font><i><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; color: #000000;">Floating NAV risk</font></i></font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;">.

If a liquidity fee is imposed by the fund, it would reduce the amount you will receive upon the redemption of your shares.

Structured notes typically are purchased in privately negotiated transactions from financial institutions and, thus, an active trading market for such instruments may not exist.</font></p> <br/><p style="TEXT-ALIGN: left; MARGIN-LEFT: 8.65pt; TEXT-INDENT: -8.65pt"><font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;">·</font></font><font><font style="WORD-SPACING: 10pt"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;"> </font></font></font><font><i><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; color: #000000;">Tax risk. </font></i></font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;">To be tax-exempt, municipal obligations generally must meet certain regulatory requirements.

It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so.

The fund also may invest in high quality, short-term structured notes, which are derivative instruments whose value is tied to underlying municipal obligations. The fund also may invest temporarily in high quality, taxable money market instruments, including when the portfolio manager believes acceptable New York municipal obligations are unavailable for investment. In addition, a portion of the fund's assets may be invested in short-term, high quality municipal obligations that do not pay income that are exempt from New York state income taxes. </font></p> <br/><p style="TEXT-ALIGN: left"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;">The fund is a money market fund subject to the maturity, quality, liquidity and diversification requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended, and seeks to maintain a stable share price of $1.00.</font></p>Example<p style="TEXT-ALIGN: left"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;">The Example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.

It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The fund's yield will fluctuate as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in securities with different interest rates. The fund may impose a fee upon the sale of your shares (a "liquidity fee") or may temporarily suspend your ability to sell shares (a redemption "gate") if the fund's liquidity falls below required minimums because of market conditions or other factors.

Although the fund invests only in high quality debt securities, the credit quality of the securities held by the fund can change rapidly in certain market environments, and the default or a significant price decline of a single holding could have the potential to cause significant deterioration of the fund's NAV. </font></p> <br/><p style="TEXT-ALIGN: left; MARGIN-LEFT: 8.65pt; TEXT-INDENT: -8.65pt"><font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;">·</font></font><font><font style="WORD-SPACING: 10pt"><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000; font-family: symbol;"> </font></font></font><font><i><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; color: #000000;">Floating NAV risk</font></i></font><font style="FONT-SIZE: 10pt; FONT-WEIGHT: normal; FONT-STYLE: normal; color: #000000;">.

While the fund is permitted to invest in the full range of government securities, the fund currently is managed so that income paid by the fund will be exempt from state and local taxes.

The fund also may invest in high quality, short-term structured notes, which are derivative instruments whose value is tied to underlying municipal obligations. The fund also may invest temporarily in high quality, taxable money market instruments, including when the portfolio manager believes acceptable New York municipal obligations are unavailable for investment.

It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The fund's yield will fluctuate as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in securities with different interest rates. The fund may impose a fee upon the sale of your shares (a "liquidity fee") or may temporarily suspend your ability to sell shares (a redemption "gate") if the fund's liquidity falls below required minimums because of market conditions or other factors.

A sharp and unexpected rise in interest rates could impair the fund's ability to maintain a stable net asset value.

The 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 hold or redeem all of your shares at the end of those periods. 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:
To pursue its goal, the fund normally invests in a diversified portfolio of high quality, short-term, dollar-denominated debt securities, including: securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities; certificates of deposit, time deposits, bankers' acceptances and other short-term securities issued by domestic or foreign banks or thrifts or their subsidiaries or branches; repurchase agreements, including tri-party repurchase agreements; asset-backed securities; municipal securities; domestic and dollar-denominated foreign commercial paper and other short-term corporate obligations, including those with floating or variable rates of interest; and dollar-denominated obligations issued or guaranteed by one or more foreign governments or any of their political subdivisions or agencies.
The fund's investments are concentrated in the banking industry, because the fund normally invests at least 25% of its net assets in domestic or dollar-denominated foreign bank obligations.
The fund is a money market fund subject to the maturity, quality, liquidity and diversification requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended, although the net asset value (NAV) of the fund's shares will "float," meaning the NAV will fluctuate with changes in the values of the fund's portfolio securities.
Principal Risks
An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. You could lose money by investing in the fund. Because the share price of the fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them. The fund's yield will fluctuate as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in securities with different interest rates. The fund may impose a fee upon the sale of shares (a "liquidity fee") or may temporarily suspend your ability to sell shares (a redemption "gate") if the fund's liquidity falls below required minimums because of market conditions or other factors. Neither The Dreyfus Corporation nor its affiliates have a legal obligation to provide financial support to the fund, and you should not expect that The Dreyfus Corporation or its affiliates will provide financial support to the fund at any time. The following are the principal risks that could reduce the fund's income level and/or share price:
· Interest rate risk. This risk refers to the decline in the prices of fixed-income securities that may accompany a rise in the overall level of interest rates. A sharp and unexpected rise in interest rates could cause the fund's share price to decline. A low interest rate environment may prevent the fund from providing a positive yield or paying fund expenses out of fund assets and could lead to a decline in the fund's share price.
· Liquidity risk. When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities in a timely manner at or near their perceived value. In such a market, the value of such securities may fall dramatically, potentially leading to a decline in the fund's share price, even during periods of declining interest rates.
· Credit risk. Failure of an issuer of a security to make timely interest or principal payments when due, or a decline or perception of a decline in the credit quality of a security, can cause the security's price to fall. Although the fund invests only in high quality debt securities, the credit quality of the securities held by the fund can change rapidly in certain market environments, and the default or a significant price decline of a single holding could have the potential to cause significant deterioration of the fund's NAV.
· Floating NAV risk. The fund does not maintain a stable NAV per share. The NAV of the fund's shares will be calculated to four decimal places and will "float," meaning the NAV will fluctuate with changes in the values of the fund's portfolio securities. You could lose money by investing in the fund.
· Liquidity fee and/or redemption gate risk. The fund may impose a fee upon the sale of your shares (a "liquidity fee") or may temporarily suspend your ability to sell shares (a redemption "gate") if the fund's liquidity falls below required minimums because of unusual market conditions, an unusually high volume of redemption requests, redemptions by a few large investors, or other reasons. If a liquidity fee is imposed by the fund, it would reduce the amount you will receive upon the redemption of your shares. A "gate" will suspend your ability to redeem your shares while the gate is imposed and may prevent the fund from being able to pay redemption proceeds within the allowable time period stated in this prospectus.
· Banking industry risk. The risks generally associated with concentrating investments in the banking industry include interest rate risk, credit risk, and regulatory developments relating to the banking industry.
· Foreign investment risk. The risks generally associated with dollar-denominated foreign investments include economic and political developments, seizure or nationalization of deposits, imposition of taxes or other restrictions on payment of principal and interest.
· U.S. Treasury securities risk. A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate.
· Government securities risk. Not all obligations of the U.S. government, its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some obligations are backed only by the credit of the issuing agency or instrumentality, and in some cases there may be some risk of default by the issuer. Any guarantee by the U.S. government or its agencies or instrumentalities of a security held by the fund does not apply to the market value of such security or to shares of the fund itself. A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity.
· Repurchase agreement counterparty risk. The fund is subject to the risk that a counterparty in a repurchase agreement and/or, for a tri-party repurchase agreement, the third party bank providing payment administration, collateral custody and management services for the transaction, could fail to honor the terms of the agreement.
· Municipal securities risk. Municipal securities may be fully or partially backed or enhanced by the taxing authority of a local government, by the current or anticipated revenues from a specific project or specific assets, or by the credit of, or liquidity enhancement provided by, a private issuer. Special factors, such as legislative changes, and state and local economic and business developments, may adversely affect the yield and/or value of the fund's investments in municipal securities.

Risk/Return Summary Fee Table Includes the following information, in plain English under rule 421(d) under the Securities Act, after Item 2 Fees and expenses of the Fund This table describes the fees and expenses that you may pay if you buy and hold shared of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $[_____] in [name of fund family] funds. Shareholder Fees (fees paid directly from your investment) 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 you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. 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 may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds. For purposes of this Item, a "New Fund" is a Fund that does not include in Form N-1A financial statements reporting operating results or that includes financial statements for the Fund's initial fiscal year reporting operating results for a period of 6 months or less. The following Instructions apply to New Funds.
This table describes the fees and expenses that you may pay if you buy and hold shared of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $[_____] in [name of fund family] funds. Include the narrative explanations in the order indicated. A Fund may modify the narrative explanations if the explanation contains comparable information to that shown. The narrative explanation regarding sales charge discounts is only required by a Fund that offers such discounts and should specify the minimum level of investment required to qualify for a discount. Modify the narrative explanation to state that Fund shares are sold on a national securities exchange at the end of the time periods indicated, and that brokerage commissions for buying and selling Fund shares through a broker are not reflected.
Total Annual Fund Operating Expenses. If the Fund is a Feeder Fund, reflect the aggregate expenses of the Feeder Fund and the Master Fund in a single fee table using the captions provided. In a footnote to the fee table, state that the table and Example reflect the expenses of both the Feeder and Master Funds. If the prospectus offers more than one Class of a Multiple Class Fund or more than one Feeder Fund that invests in the same Master Fund, provide a separate response for each Class or Feeder Fund. Base the percentages of "Annual Fund Operating Expenses" on amounts incurred during the Fund's most recent fiscal year, but include in expenses amounts that would have been incurred absent expense reimbursement or fee waiver arrangements. If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."
Management Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."
Investment Objectives/Goals. Disclose the Fund's investment objectives or goals. A Fund also may identify its type or category (e.g., that it is a Money Market Fund or a balanced fund).
Investment Objectives/Goals. Disclose the Fund's investment objectives or goals. A Fund also may identify its type or category (e.g., that it is a Money Market Fund or a balanced fund).
"Other Expenses" include all expenses not otherwise disclosed in the table that are deducted from the Fund's assets or charged to all shareholder accounts. The amount of expenses deducted from the Fund's assets are the amounts shown as expenses in the Fund's statement of operations (including increases resulting from complying with paragraph 2(g) of rule 6-07 of Regulation S-X [17 CFR 210.6-07]). "Other Expenses" do not include extraordinary expenses as determined under generally accepted accounting principles (see Accounting Principles Board Opinion No. 30). If extraordinary expenses were incurred that materially affected the Fund's "Other Expenses," disclose in a footnote to the table what "Other Expenses" would have been had the extraordinary expenses been included.
If the Fund has annual returns for at least one calendar year, provide a table showing the Fund's (A) average annual total return; (B) average annual total return (after taxes on distributions); and (C) average annual total return (after taxes on distributions and redemption). A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____)

Narrative Risk Disclosure. A Fund may, in responding to this Item, describe the types of investors for whom the Fund is intended or the types of investment goals that may be consistent with an investment in the Fund.
Risk/Return Summary Investment Objectives/Goals Include the following information, in plain English under rule 421(d) under the Securities Act, in the order and subject matter indicated
Principal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.
Principal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.
The 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 hold or redeem all of your shares at the end of those periods. 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:
To pursue its goal, the fund normally invests in a diversified portfolio of high quality, short-term, dollar-denominated debt securities, including: securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities; certificates of deposit, time deposits, bankers' acceptances and other short-term securities issued by domestic or foreign banks or thrifts or their subsidiaries or branches; repurchase agreements, including tri-party repurchase agreements; asset-backed securities; municipal securities; domestic and dollar-denominated foreign commercial paper and other short-term corporate obligations, including those with floating or variable rates of interest; and dollar-denominated obligations issued or guaranteed by one or more foreign governments or any of their political subdivisions or agencies.
The fund's investments are concentrated in the banking industry, because the fund normally invests at least 25% of its net assets in domestic or dollar-denominated foreign bank obligations.
The fund is a money market fund subject to the maturity, quality, liquidity and diversification requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended, although the net asset value (NAV) of the fund's shares will "float," meaning the NAV will fluctuate with changes in the values of the fund's portfolio securities.
An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. You could lose money by investing in the fund. Because the share price of the fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them. The fund's yield will fluctuate as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in securities with different interest rates. The fund may impose a fee upon the sale of shares (a "liquidity fee") or may temporarily suspend your ability to sell shares (a redemption "gate") if the fund's liquidity falls below required minimums because of market conditions or other factors. Neither The Dreyfus Corporation nor its affiliates have a legal obligation to provide financial support to the fund, and you should not expect that The Dreyfus Corporation or its affiliates will provide financial support to the fund at any time. The following are the principal risks that could reduce the fund's income level and/or share price:
· Interest rate risk. This risk refers to the decline in the prices of fixed-income securities that may accompany a rise in the overall level of interest rates. A sharp and unexpected rise in interest rates could cause the fund's share price to decline. A low interest rate environment may prevent the fund from providing a positive yield or paying fund expenses out of fund assets and could lead to a decline in the fund's share price.
· Liquidity risk. When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities in a timely manner at or near their perceived value. In such a market, the value of such securities may fall dramatically, potentially leading to a decline in the fund's share price, even during periods of declining interest rates.
· Credit risk. Failure of an issuer of a security to make timely interest or principal payments when due, or a decline or perception of a decline in the credit quality of a security, can cause the security's price to fall. Although the fund invests only in high quality debt securities, the credit quality of the securities held by the fund can change rapidly in certain market environments, and the default or a significant price decline of a single holding could have the potential to cause significant deterioration of the fund's NAV.
· Floating NAV risk. The fund does not maintain a stable NAV per share. The NAV of the fund's shares will be calculated to four decimal places and will "float," meaning the NAV will fluctuate with changes in the values of the fund's portfolio securities. You could lose money by investing in the fund.
· Liquidity fee and/or redemption gate risk. The fund may impose a fee upon the sale of your shares (a "liquidity fee") or may temporarily suspend your ability to sell shares (a redemption "gate") if the fund's liquidity falls below required minimums because of unusual market conditions, an unusually high volume of redemption requests, redemptions by a few large investors, or other reasons. If a liquidity fee is imposed by the fund, it would reduce the amount you will receive upon the redemption of your shares. A "gate" will suspend your ability to redeem your shares while the gate is imposed and may prevent the fund from being able to pay redemption proceeds within the allowable time period stated in this prospectus.
· Banking industry risk. The risks generally associated with concentrating investments in the banking industry include interest rate risk, credit risk, and regulatory developments relating to the banking industry.
· Foreign investment risk. The risks generally associated with dollar-denominated foreign investments include economic and political developments, seizure or nationalization of deposits, imposition of taxes or other restrictions on payment of principal and interest.
· U.S. Treasury securities risk. A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate.
· Government securities risk. Not all obligations of the U.S. government, its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some obligations are backed only by the credit of the issuing agency or instrumentality, and in some cases there may be some risk of default by the issuer. Any guarantee by the U.S. government or its agencies or instrumentalities of a security held by the fund does not apply to the market value of such security or to shares of the fund itself. A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity.
· Repurchase agreement counterparty risk. The fund is subject to the risk that a counterparty in a repurchase agreement and/or, for a tri-party repurchase agreement, the third party bank providing payment administration, collateral custody and management services for the transaction, could fail to honor the terms of the agreement.
· Municipal securities risk. Municipal securities may be fully or partially backed or enhanced by the taxing authority of a local government, by the current or anticipated revenues from a specific project or specific assets, or by the credit of, or liquidity enhancement provided by, a private issuer. Special factors, such as legislative changes, and state and local economic and business developments, may adversely affect the yield and/or value of the fund's investments in municipal securities.
You could lose money by investing in the fund. Because the share price of the fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them.
An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.
