INFORMATION.

Introduction

Each fund is a money market mutual fund with a separate investment portfolio.
The operations and results of one fund are unrelated to those of the other fund.
This combined prospectus has been prepared for the convenience of investors so
that investors can consider two investment choices in one document.

As a money market fund, each fund is subject to maturity, quality and
diversification requirements designed to help it maintain a stable share price.

Generally, each fund is required to invest at least 95% of its assets in the
securities of issuers with the highest credit rating, with the remainder
invested in securities with the second-highest credit rating, or the unrated
equivalent as determined by Dreyfus. Each fund intends to purchase securities
with the highest credit rating only, or the unrated equivalent.

An investment in a fund is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. Although each fund seeks
to preserve the value of a shareholder's investment at $1.00 per share, it is
possible to lose money by investing in a fund.


Concepts to understand

MONEY MARKET FUND: a specific type of fund that seeks to maintain a $1.00 price
per share. Money market funds are subject to strict federal requirements and
must:

(pound) maintain an average dollar-weighted portfolio maturity of 90 days or
        less

(pound) buy individual securities that have remaining maturities of 13 months or
        less

(pound) invest only in high quality, dollar-denominated obligations


CREDIT RATING: a measure of the issuer's expected ability to make all required
interest and principal payments in a timely manner. An issuer with the highest
credit rating has a very strong degree of certainty (or safety) with respect to
making all payments. An issuer with the second-highest credit rating has a
strong capacity to make all payments, but the degree of safety is somewhat less.


The Funds
<PAGE>

Dreyfus Institutional Preferred Money Market Fund

GOAL/APPROACH


The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity. To pursue this goal,
the fund invests in a diversified portfolio of high quality, short-term debt
securities, including:

(pound)  securities issued or guaranteed by the U.S. government or its agencies
         or instrumentalities

(pound)  certificates of deposit, time deposits, bankers' acceptances and other
         short-term securities issued by domestic or foreign banks or their
         subsidiaries or branches

(pound)  repurchase agreements

(pound)  domestic and dollar-denominated foreign commercial paper and other
         short-term corporate obligations, including those with floating or
         variable rates of interest

(pound)  asset-backed securities


Normally, the fund invests at least 25% of its total assets in bank obligations

MAIN RISKS

The fund's yield will fluctuate, as market conditions and interest rates change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.



While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

(pound)  interest rates could rise sharply, causing the value of the fund's
         securities, and share price, to drop

(pound)  any of the fund's holdings could have its credit rating downgraded or
         could default

(pound)  the risks generally associated with concentrating investments in the
         banking industry, such as interest rate risk, credit risk and
         regulatory developments relating to the banking industry

(pound)  the risks generally associated with dollar-denominated foreign
         investments, such as economic and political developments, seizure or
         nationalization of deposits, imposition of taxes or other restrictions
         on the payment of principal and interest

Concepts to understand


REPURCHASE AGREEMENT: a U.S. commercial bank or securities dealer sells
typically U.S. government securities to the fund and agrees to repurchase them
at an agreed-upon date (usually the next day) and price. These agreements offer
the fund a means of investing money for a short period of time.

PAST PERFORMANCE

The bar chart and table below show some of the risks of investing in the fund.

EXPENSES

Fund investors pay certain fees and expenses in connection with the fund, which
are described in the table below. Annual fund operating expenses are paid out of
fund assets, so their effect is included in the share price. The fund has no
sales charge (load) or Rule 12b-1 distribution fees.

</TABLE>


This example shows what an investor could pay in expenses over time. It uses the
same hypothetical conditions other funds use in their prospectuses: $10,000
initial investment, 5% total return each year and no changes in expenses. The
figures shown would be the same whether the investor sold the shares at the end
of a period or kept them. Because actual return and expenses will be different,
the example is for comparison only.


What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives an investor the opportunity to participate in financial markets. It
strives to reach its stated goal, although as with all mutual funds, it cannot
offer guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. An investor could lose money in this fund, but also has the
potential to make money.

Concepts to understand

MANAGEMENT FEE: the fee paid to Dreyfus for managing the fund. Unlike the
arrangements between most investment advisers and their funds, Dreyfus pays all
fund expenses except for brokerage fees, taxes, interest, fees and expenses of
the independent board members, fees and expenses of independent counsel to the
fund and to the independent board members, and extraordinary expenses.

MANAGEMENT


The investment adviser for each fund is The Dreyfus Corporation, 200 Park
Avenue, New York, New York 10166. Founded in 1947, Dreyfus manages more than
$129 billion in over 160 mutual fund portfolios. For the past fiscal year,
Dreyfus Institutional Preferred Money Market Fund paid Dreyfus a management fee
at the annual rate of 0.10% of the fund's average daily net assets. Dreyfus
Institutional Preferred Plus Money Market Fund has agreed to pay Dreyfus an
annual management fee of 0.10% of the fund's average daily net assets. Dreyfus
is the primary mutual fund business of Mellon Financial Corporation, a global
financial services company with approximately $2.5 trillion of assets under
management, administration or custody, including approximately $485 billion
under management. Mellon provides wealth management, global investment services
and a comprehensive array of banking services to individuals, businesses and
institutions. Mellon is headquartered in Pittsburgh, Pennsylvania.

The funds, Dreyfus and Dreyfus Service Corporation (each fund's distributor)
each have adopted a code of ethics that permits its personnel, subject to such
code, to invest in securities, including securities that may be purchased or
held by each fund. The Dreyfus code of ethics restricts the personal securities
transactions of its employees, and requires portfolio managers and other
investment personnel to comply with the code's preclearance and disclosure
procedures. Its primary purpose is to ensure that personal trading by Dreyfus
employees does not disadvantage any Dreyfus-managed fund.

transfer agent is open. Orders in proper form will be priced at the NAV next
calculated after the orders and Federal Funds are received by the fund's
custodian or other authorized entity.


Investors whose orders are placed and payments are received in or converted into
Federal Funds by the fund's custodian by 12:00 noon, will become effective at
the price determined at 5:00 p.m. and will receive the dividend declared on that
day. Except as described below, investors whose payments are received in or
converted into Federal Funds after 12:00 noon by the fund's custodian, will
begin to accrue dividends on the following business day.

Orders in proper form received by Dreyfus Institutional Services Division after
12:00 noon, but prior to 5:00 p.m., and payments for which are received by the
fund's custodian by 6:00 p.m., will become effective at the price determined at
5:00 p.m., and the shares so purchased will receive the dividend declared on
such day.


For each fund, all times are Eastern time.

Each fund's investments are valued based on amortized cost.

--------------------------------------------------------------------------------

REGULAR ACCOUNTS                $1 BILLION*            NO MINIMUM

*The minimum initial investment is $1 billion, unless: (a) the investor has
invested at least $1 billion in one fund, in which case there would be no
minimum initial investment amount for the other fund; or (b) the investor has,
in the opinion of Dreyfus Institutional Services Division, adequate intent and
availability of assets to reach a future aggregate level of investment of $1
billion in the funds.


Concepts to understand


NET ASSET VALUE (NAV): a mutual fund's share price on a given day. A fund's NAV
is calculated by dividing the value of its net assets by the number of existing
shares.

AMORTIZED COST: a method of valuing a money market fund's portfolio securities,
which does not take into account unrealized gains and losses. As a result,
portfolio securities are valued at their acquisition cost, adjusted over time
based on the discounts or premiums reflected in their purchase price. This
method of valuation is designed to permit a fund to maintain a stable net asset
value.

<PAGE>
Selling shares

Investors may sell (redeem) shares at any time and the shares will be sold at
the next determined NAV. If a request for redemption is received in proper form,
and transmitted to the fund's custodian by 5:00 p.m. Eastern time, the proceeds
of the redemption, if transfer by wire is requested, ordinarily will be
transmitted in Federal Funds on the same day, and the shares will not receive
the dividend declared on that day. If the request is received later that day,
the shares will receive the dividend declared on that day, and the proceeds of
redemption, if wire transfer is requested, ordinarily will be transmitted in
Federal Funds on the next business day. Orders will be processed promptly and
investors generally will receive the proceeds within a week. Any certificates
representing fund shares being sold must be returned with the redemption
request.

General policies

Unless an investor declines telephone privileges on the application, the
investor may be responsible for any fraudulent telephone order as long as
Dreyfus takes reasonable measures to verify the order.


Each fund reserves the right to:

(pound)  refuse any purchase request or exchange request that could adversely
         affect the fund or its operations

(pound)  change or discontinue its exchange privilege, or temporarily suspend
         this privilege during unusual market conditions

(pound)  change its minimum investment amounts

(pound)  delay sending out redemption proceeds for up to seven days (generally
         applies only in cases of very large redemptions, excessive trading or
         during unusual market conditions)

Each fund also reserves the right to make a "redemption in kind" -- payment in
portfolio securities rather than cash -- if the amount the investor is redeeming
is large enough to affect fund operations (for example, if it represents more
than 1% of the fund's assets).


Account Information
<PAGE>

DISTRIBUTIONS AND TAXES


Each fund usually declares dividends from its net investment income every day
the New York Stock Exchange or the fund's transfer agent is open, and pays such
dividends to its shareholders once a month. Each fund distributes any net
capital gains it has realized once a year. Dividends and distributions will be
reinvested in the fund unless the investor instructs the fund otherwise. There
are no fees or sales charges on reinvestments.


Fund dividends and distributions are taxable to most U.S. investors as ordinary
income (unless the investor's investment is in a tax-advantaged account). The
tax status of any distribution is the same regardless of how long the investor
has been in the fund and whether distributions are reinvested or taken in cash.
The tax status of dividends and distributions will be detailed in an annual tax
statement from the fund.

Because everyone's tax situation is unique, an investor should always consult a
tax professional about federal, state and local tax consequences.


SERVICES FOR FUND INVESTORS

Exchange privilege

An investor may purchase, in exchange for shares of one fund, shares of the
other fund. An exchange may be requested in writing or by telephone. Any new
account established through an exchange will have the same privileges as the
original account (as long as they are available). There is currently no fee for
exchanges.


Dreyfus Auto-Exchange privilege

Dreyfus Auto-Exchange privilege enables an investor to invest regularly (on a
monthly, semi-monthly, quarterly or annual basis), in exchange for shares of one
fund, in shares of the other fund, if the investor is a shareholder in such
other fund. There is currently no fee for this privilege.

                    DESCRIPTION OF THE COMPANY AND THE FUNDS

          The Company is a Massachusetts business trust that was formed and
commenced operations on June 11, 1997. Prior to ________, 2000, the Company's
name was Dreyfus Institutional Preferred Money Market Fund. Each Fund is a
separate portfolio of the Company, an open-end management investment company,
known as a money market mutual fund. Each Fund is a diversified fund, which
means that, with respect to 75% of the Fund's total assets, the Fund will not
invest more than 5% of its assets in the securities of any single issuer.

          The Dreyfus Corporation (the "Manager") serves as each Fund's
investment adviser.

          Dreyfus Service Corporation (the "Distributor") is the distributor of
each Fund's shares.


CERTAIN PORTFOLIO SECURITIES


          The following information supplements and should be read in
conjunction with the Funds' Prospectus.

          U.S. GOVERNMENT SECURITIES. (All Funds) Each Fund may invest in
securities issued or guaranteed by the U.S. Government or its agencies or
instrumentalities, which include U.S. Treasury securities, that differ in their
interest rates, maturities and times of issuance. Some obligations issued or
guaranteed by U.S. Government agencies and instrumentalities are supported by
the full faith and credit of the U.S. Treasury; others by the right of the
issuer to borrow from the Treasury; others by discretionary authority of the
U.S. Government to purchase certain obligations of the agency or
instrumentality; and others only by the credit of the agency or instrumentality.
These securities bear fixed, floating or variable rates of interest. While the
U.S. Government currently provides financial support to such U.S.
Government-sponsored agencies or instrumentalities, no assurance can be given
that it will always do so, since it is not so obligated by law.

          FOREIGN GOVERNMENT OBLIGATIONS; SECURITIES OF SUPRANATIONAL ENTITIES.
(Dreyfus Institutional Preferred Plus Money Market Fund only) The Fund may
invest in obligations issued or guaranteed by one or more foreign governments or
any of their political subdivisions, agencies or instrumentalities that are
determined by the Manager to be of comparable quality to the other obligations
in which the Fund may invest. Such securities also include debt obligations of
supranational entities. Supranational Entities include organizations designated
or supported by governmental entities to promote economic reconstruction or
development and international banking institutions and related government
agencies. Examples include the International Bank for Reconstruction and
Development (the World Bank), the European Coal and Steel Community, the Asian
Development Bank and the InterAmerican Development Bank.

          BANK OBLIGATIONS. (All Funds) Each Fund may purchase certificates of
deposit ("CDs"), time deposits ("TDs"), bankers' acceptances and other
short-term obligations issued by domestic banks, foreign subsidiaries or foreign
branches of domestic banks, domestic and foreign branches of foreign banks,
domestic savings and loan associations and other banking institutions.


          CDs are negotiable certificates evidencing the obligation of a bank to
repay funds deposited with it for a specified period of time.

          TDs are non-negotiable deposits maintained in a banking institution
for a specified period of time (in no event longer than seven days) at a stated
interest rate.

          Bankers' acceptances are credit instruments evidencing the obligation
of a bank to pay a draft drawn on it by a customer. These instruments reflect
the obligation both of the bank and the drawer to pay the face amount of the
instrument upon maturity. The other short-term obligations may include
uninsured, direct obligations bearing fixed, floating or variable interest
rates.


          Domestic commercial banks organized under Federal law are supervised
and examined by the Comptroller of the Currency and are required to be members
of the Federal Reserve System and to have their deposits insured by the Federal
Deposit Insurance Corporation (the "FDIC"). Domestic banks organized under state
law are supervised and examined by state banking authorities but are members of
the Federal Reserve System only if they elect to join. In addition, state banks
whose CDs may be purchased by the Fund are insured by the Bank Insurance Fund
administered by the FDIC (although such insurance may not be of material benefit
to the Fund, depending on the principal amount of the CDs of each bank held by
the Fund) and are subject to Federal examination and to a substantial body of
Federal law and regulation. As a result of Federal or state laws and
regulations, domestic branches of domestic banks whose CDs may be purchased by a
Fund are, among other things, generally required to maintain specified levels of
reserves, are limited in the amounts which they can loan to a single borrower
and are subject to other regulation designed to promote financial soundness.
However, not all of such laws and regulations apply to the foreign branches of
domestic banks.


          Obligations of foreign branches of domestic banks, foreign
subsidiaries of domestic banks and domestic and foreign branches of foreign
banks, such as CDs and TDs, may be general obligations of the parent banks in
addition to the issuing branch, or may be limited by the terms of a specific
obligation and governmental regulation. Such obligations are subject to
different risks than are those of domestic banks. These risks include foreign
economic and political developments, foreign governmental restrictions that may
adversely affect payment of principal and interest on the obligations, foreign
exchange controls and foreign withholding and other taxes on interest income.
Foreign branches and subsidiaries are not necessarily subject to the same or
similar regulatory requirements that apply to domestic banks, such as mandatory
reserve requirements, loan limitations, and accounting, auditing and financial
recordkeeping requirements. In addition, less information may be publicly
available about a foreign branch of a domestic bank or about a foreign bank than
about a domestic bank.

          Obligations of United States branches of foreign banks may be general
obligations of the parent bank in addition to the issuing branch, or may be
limited by the terms of a specific obligation or by Federal or state regulation
as well as governmental action in the country in which the foreign bank has its
head office. A domestic branch of a foreign bank with assets in excess of $1
billion may or may not be subject to reserve requirements imposed by the Federal
Reserve System or by the state in which the branch is located if the branch is
licensed in that state.

         In addition, Federal branches licensed by the Comptroller of the
Currency and branches licensed by certain states ("State Branches") may be
required to: (1) pledge to the regulator, by depositing assets with a designated
bank within the state, a certain percentage of their assets as fixed from time
to time by the appropriate regulatory authority; and (2) maintain assets within
the state in an amount equal to a specified percentage of the aggregate amount
of liabilities of the foreign bank payable at or through all of its agencies or
branches within the state. The deposits of Federal and State Branches generally
must be insured by the FDIC if such branches take deposits of less than
$100,000.

          In view of the foregoing factors associated with the purchase of CDs
and TDs issued by foreign branches of domestic banks, by foreign subsidiaries of
domestic banks, by foreign branches of foreign banks or by domestic branches of
foreign banks, the Manager carefully evaluates such investments on a
case-by-case basis.


          Each Fund may purchase CDs issued by banks, savings and loan
associations and similar thrift institutions with less than $1 billion in
assets, whose deposits are insured by the FDIC, provided the Fund purchases any
such CD in a principal amount of not more than $100,000, which amount would be
fully insured by the Bank Insurance Fund or the Savings Association Insurance
Fund administered by the FDIC. Interest payments on such a CD are not so
insured. The Fund will not own more than one such CD per such issuer.

          COMMERCIAL PAPER. (All Funds) Each Fund may purchase commercial paper
consisting of short-term, unsecured promissory notes issued to finance
short-term credit needs. The commercial paper purchased by the Funds will
consist only of direct obligations issued by domestic and foreign entities. The
other corporate obligations in which each Fund may invest consist of high
quality, U.S. dollar denominated short-term bonds and notes (including variable
amount master demand notes).

          FLOATING AND VARIABLE RATE OBLIGATIONS. (All Funds) Each Fund may
purchase floating and variable rate demand notes and bonds, which are
obligations ordinarily having stated maturities in excess of 13 months, but
which permit the holder to demand payment of principal at any time, or at
specified intervals not exceeding 13 months, in each case upon not more than 30
days' notice. Variable rate demand notes include master demand notes which are
obligations that permit the Fund to invest fluctuating amounts, at varying rates
of interest, pursuant to direct arrangements between the Fund, as lender, and
the borrower. These obligations permit daily changes in the amounts borrowed.
Because these obligations are direct lending arrangements between the lender and
borrower, it is not contemplated that such instruments generally will be traded,
and there generally is no established secondary market for these obligations,
although they are redeemable at face value, plus accrued interest. Accordingly,
where these obligations are not secured by letters of credit or other credit
support arrangements, the Fund's right to redeem is dependent on the ability of
the borrower to pay principal and interest on demand.

          REPURCHASE AGREEMENTS. (All Funds) Each Fund may enter into repurchase
agreements. In a repurchase agreement, the Fund buys, and the seller agrees to
repurchase, a security at a mutually agreed upon time and price (usually within
seven days). The repurchase agreement thereby determines the yield during the
purchaser's holding period, while the seller's obligation to repurchase is
secured by the value of the underlying security. The Funds' custodian will have
custody of, and will segregate, securities acquired by a Fund under a repurchase
agreement. Repurchase agreements are considered by the staff of the Securities
and Exchange Commission to be loans by the Fund that enters into them.
Repurchase agreements could involve risks in the event of a default or
insolvency of the other party to the agreement, including possible delays or
restrictions upon the Fund's ability to dispose of the underlying securities. In
an attempt to reduce the risk of incurring a loss on a repurchase agreement,
each Fund will enter into repurchase agreements only with domestic banks with
total assets in excess of $1 billion, or primary government securities dealers
reporting to the Federal Reserve Bank of New York, with respect to securities of
the type in which the Fund may invest, and will require that additional
securities be deposited with it if the value of the securities purchased should
decrease below the resale price.

          ASSET-BACKED SECURITIES. (All Funds) Each Fund may invest in
asset-backed securities, which are securities issued by special purpose entities
whose primary assets consist of a pool of mortgages, loans, receivables or other
assets. Payment of principal and interest may depend largely on the cash flows
generated by the assets backing the securities and in certain cases, supported
by letters of credit, surety bonds or other forms of credit or liquidity
enhancements. The value of these asset-backed securities also may be affected by
the creditworthiness of the servicing agent for the pool of assets, the
originator of the loans or receivables or the financial institutions providing
the credit support.

          ILLIQUID SECURITIES. (All Funds) Each Fund may invest up to 10% of the
value of its net assets in securities as to which a liquid trading market does
not exist, provided such investments are consistent with the Fund's investment
objective. Such securities may include securities that are not readily
marketable, such as securities that are subject to legal or contractual
restrictions on resale, and repurchase agreements providing for settlement in
more than seven days after notice. As to these securities, the Fund is subject
to a risk that should the Fund desire to sell them when a ready buyer is not
available at a price the Fund deems representative of their value, the value of
the Fund's net assets could be adversely affected.


INVESTMENT TECHNIQUES


          The following information supplements and should be read in
conjunction with the Funds' Prospectus.

          BORROWING MONEY. (All Funds) Each Fund is permitted to borrow to the
extent permitted under the Investment Company Act of 1940, as amended (the "1940
Act"), which permits an investment company to borrow an amount up to 33-1/3% of
the value of its total assets. Except for when it enters into reverse repurchase
agreements described below, each Fund currently intends to borrow money only for
temporary or emergency (not leveraging) purposes in an amount up to 15% of the
value of its total assets (including the amount borrowed) at the time the
borrowing is made. While such borrowings exceed 5% of the value of a Fund's
total assets, the Fund will not make any additional investments. In addition,
each Fund may borrow for investment purposes on a secured basis through entering
into reverse repurchase agreements, as described below.

          REVERSE REPURCHASE AGREEMENTS. (All Funds) Each Fund may enter into
reverse repurchase agreements with banks, broker/dealers or other financial
institutions. These agreements involve the transfer by the Fund of an underlying
debt instrument in return for cash proceeds based on a percentage of the value
of the security. The Fund retains the right to receive interest and principal
payments on the security. The Fund will use the proceeds of reverse repurchase
agreements only to make investments which generally either mature, or have a
demand feature to resell to the issuer, at a date simultaneous with or prior to
the expiration of the reverse repurchase agreement. At an agreed upon future
date, the Fund repurchases the security, at principal, plus accrued interest. As
a result of these transactions, the Fund is exposed to greater potential
fluctuations in the value of its assets and its net asset value per share. These
borrowings will be subject to interest costs which may or may not be recovered
by appreciation of the securities purchased; in certain cases, interest costs
may exceed the return received on the securities purchased. Reverse repurchase
agreements constitute borrowings under the 1940 Act and, therefore, together
with other borrowings, will be subject to the limitations on borrowing set forth
in the 1940 Act. To the extent a Fund enters into a reverse repurchase
agreement, the Fund will segregate permissible liquid assets at least equal to
the aggregate amount of its reverse repurchase obligations, plus accrued
interest, in certain cases, in accordance with releases promulgated by the
Securities and Exchange Commission.

          LENDING PORTFOLIO SECURITIES. (All Funds) Each Fund may lend
securities from its portfolio to brokers, dealers and other financial
institutions needing to borrow securities to complete certain transactions. The
Fund continues to be entitled to payments in amounts equal to the interest or
other distributions payable on the loaned securities which affords the Fund an
opportunity to earn interest on the amount of the loan and on the loaned
securities' collateral. Loans of portfolio securities may not exceed 33-1/3% of
the value of the Fund's total assets, and the Fund will receive collateral
consisting of cash or U.S. Government securities which will be maintained at all
times in an amount equal to at least 100% of the current market value of the
loaned securities. Such loans are terminable by the Fund at any time upon
specified notice. The Fund might experience risk of loss if the institution with
which it has engaged in a portfolio loan transaction breaches its agreement with
the Fund. In connection with its securities lending transactions, a Fund may
return to the borrower or a third party which is unaffiliated with the Fund, and
which is acting as a "placing broker," a part of the interest earned from the
investment of collateral received for securities loaned.

          FORWARD COMMITMENTS. (All Funds) Each Fund may purchase money market
instruments on a forward commitment or when-issued basis, which means that
delivery and payment take place a number of days after the date of the
commitment to purchase. The payment obligation and the interest rate receivable
on a forward commitment or when-issued security are fixed when the Fund enters
into the commitment, but the Fund does not make payment until it receives
delivery from the counterparty. A Fund will commit to purchase such securities
only with the intention of actually acquiring the securities, but the Fund may
sell these securities before the settlement date if it is deemed advisable. The
Fund will segregate permissible liquid assets at least equal at all times to the
amount of the Fund's purchase commitments.


          Securities purchased on a forward commitment or when-issued basis are
subject to changes in value (generally changing in the same way, i.e.,
appreciating when interest rates decline and depreciating when interest rates
rise) based upon the public's perception of the creditworthiness of the issuer
and changes, real or anticipated, in the level of interest rates. Securities
purchased on a forward commitment or when-issued basis may expose the Fund to
risks because they may experience such fluctuations prior to their actual
delivery. Purchasing securities on a when-issued basis can involve the
additional risk that the yield available in the market when the delivery takes
place actually may be higher than that obtained in the transaction itself.
Purchasing securities on a forward commitment or when-issued basis when the Fund
is fully or almost fully invested may result in greater potential fluctuation in
the value of the Fund's net assets and its net asset value per share.

INVESTMENTS CONSIDERATIONS AND RISKS


          GENERAL. (All Funds) Each Fund attempts to increase yields by trading
to take advantage of short-term market variations. This policy is expected to
result in high portfolio turnover but should not adversely affect the Funds
since the Funds usually do not pay brokerage commissions when purchasing
short-term obligations. The value of the portfolio securities held by a Fund
will vary inversely to changes in prevailing interest rates. Thus, if interest
rates have increased from the time a security was purchased, such security, if
sold, might be sold at a price less than its cost. Similarly, if interest rates
have declined from the time a security was purchased, such security, if sold,
might be sold at a price greater than its purchase cost. In either instance, if
the security was purchased at face value and held to maturity, no gain or loss
would be realized.

          BANK SECURITIES. (All Funds) To the extent a Fund's investments are
concentrated in the banking industry, the Fund will have correspondingly greater
exposure to the risk factors which are characteristic of such investments.
Sustained increases in interest rates can adversely affect the availability or
liquidity and cost of capital funds for a bank's lending activities, and a
deterioration in general economic conditions could increase the exposure to
credit losses. In addition, the value of and the investment return on the Fund's
shares could be affected by economic or regulatory developments in or related to
the banking industry, which industry also is subject to the effects of
competition within the banking industry as well as with other types of financial
institutions. Each Fund, however, will seek to minimize its exposure to such
risks by investing only in debt securities which are determined to be of highest
quality.

          FOREIGN SECURITIES. (All Funds) Since a Fund's portfolio may contain
securities issued by foreign branches of domestic banks, domestic and foreign
branches of foreign banks, and commercial paper issued by foreign issuers, the
Fund may be subject to additional investment risks with respect to such
securities that are different in some respects from those incurred by a fund
which invests only in debt obligations of U.S. domestic issuers, although such
obligations may be higher yielding when compared to the securities of U.S.
domestic issuers. Such risks include possible future political and economic
developments, seizure or nationalization of foreign deposits, imposition of
foreign withholding taxes on interest income payable on the securities,
establishment of exchange controls, or adoption of other foreign governmental
restrictions which might adversely affect the payment of principal and interest
on these securities.

          SIMULTANEOUS INVESTMENTS. (All Funds) Investment decisions for each
Fund are made independently from those of the other Fund and other investment
companies advised by the Manager. If, however, such other Fund or investment
companies desire to invest in, or dispose of, the same securities as the Fund,
available investments or opportunities for sales will be allocated equitably to
each. In some cases, this procedure may adversely affect the size of the
position obtained for or disposed of by a Fund or the price paid or received by
a Fund.


INVESTMENT RESTRICTIONS


          Each Fund's investment objective is a fundamental policy, which cannot
be changed without approval by the holders of a majority (as defined in the 1940
Act) of the Fund's outstanding voting shares. In addition, each Fund has adopted
investment restrictions numbered 1 through 9 as fundamental policies. Investment
restrictions numbered 10 and 11 are not fundamental policies and may be changed,
as to a Fund, by vote of a majority of the Company's Board members at any time.
Neither Fund may:


          1. Invest in commodities.


          2. Borrow money, except to the extent permitted under the 1940 Act,
which currently limits borrowing to up to 33-1/3% of the value of the Fund's
total assets.


          3. Purchase or sell securities on margin.

          4. Issue any senior security (as such term is defined in Section 18(f)
of the 1940 Act).

          5. Act as underwriter of securities of other issuers, except to the
extent the Fund may be deemed an underwriter under the Securities Act of 1933,
as amended, by virtue of disposing of portfolio securities.

          6. Purchase, hold or deal in real estate, or oil, gas, or other
mineral leases or exploration or development programs, but the Fund may purchase
and sell securities that are secured by real estate or issued by companies that
invest in or deal in real estate.


          7. Make loans to others except through the purchase of debt
obligations and the entry into repurchase agreements. However, the Fund may lend
its portfolio securities in an amount not to exceed 33-1/3% of the value of its
total assets. Any loans of portfolio securities will be made according to
guidelines established by the Securities and Exchange Commission and the
Company's Board.


          8. Invest more than 5% of its assets in the obligations of any one
issuer, except that up to 25% of the value of the Fund's total assets may be
invested without regard to any such limitations.

          9. Invest less than 25% of its total assets in securities issued by
banks or invest more than 25% in the securities of issuers in any other
industry, provided that there shall be no limitation on the purchase of
obligations issued or guaranteed by the U.S. Government, its agencies or
instrumentalities. Notwithstanding the foregoing, for temporary defensive
purposes the Fund may invest less than 25% of its assets in bank obligations.

          10. Pledge, mortgage, hypothecate or otherwise encumber its assets,
except to the extent necessary to secure permitted borrowings and to the extent
related to the deposit of assets in escrow in connection with the purchase of
securities on a when-issued or forward commitment basis.

          11. Enter into repurchase agreements providing for settlement in more
than seven days after notice or purchase securities which are illiquid if, in
the aggregate, more than 10% of the value of the Fund's net assets would be so
invested.

          If a percentage restriction is adhered to at the time of investment, a
later increase or decrease in percentage resulting from a change in values or
assets will not constitute a violation of that restriction.

                             MANAGEMENT ARRANGEMENTS


          INVESTMENT ADVISER. The Manager is a wholly-owned subsidiary of Mellon
Bank, N.A., which is a wholly-owned subsidiary of Mellon Financial Corporation
("Mellon"). Mellon is a global multibank financial holding company incorporated
under Pennsylvania law in 1971 and registered under the Federal Bank Holding
Company Act of 1956, as amended. Mellon provides a comprehensive range of
financial products and services in domestic and selected international markets.
Mellon is among the twenty largest bank holding companies in the United States
based on total assets.

          The Manager provides management services pursuant to the Management
Agreement (the "Agreement") between the Manager and the Company. As to each
Fund, the Agreement is subject to annual approval by (i) the Company's Board or
(ii) vote of a majority (as defined in the 1940 Act) of the Fund's outstanding
voting securities, provided that in either event the continuance also is
approved by a majority of the Board members who are not "interested persons" (as
defined in the 1940 Act) of the Company or the Manager, by vote cast in person
at a meeting called for the purpose of voting on such approval. As to each Fund,
the Agreement is terminable without penalty on 60 days' notice by the Board or
by vote of the holders of a majority of the Fund's shares or, upon not less than
90 days' notice, by the Manager. The Agreement will terminate automatically, as
to the relevant Fund, in the event of its assignment (as defined in the 1940
Act).


          The following persons are officers and/or directors of the Manager:
Christopher M. Condron, Chairman of the Board and Chief Executive Officer;
Stephen E. Canter, President, Chief Operating Officer, Chief Investment Officer
and a director; Thomas F. Eggers, Vice Chairman--Institutional and a director;
Lawrence S. Kash, Vice Chairman; J. David Officer, Vice Chairman and a director;
Ronald P. O'Hanley III, Vice Chairman; William T. Sandalls, Jr., Executive Vice
President; Stephen R. Byers, Senior Vice President; Patrice M. Kozlowski, Senior
Vice President--Corporate Communications; Mark N. Jacobs, Vice President,
General Counsel and Secretary; Diane P. Durnin, Vice President--Product
Development; Mary Beth Leibig, Vice President--Human Resources; Ray Van Cott,
Vice President--Information Systems; Theodore A. Schachar, Vice President--Tax;
Wendy Strutt, Vice President; William H. Maresca, Controller; James Bitetto,
Assistant Secretary; Steven F. Newman, Assistant Secretary; and Mandell L.
Berman, Burton C. Borgelt, Steven G. Elliot, Martin G. McGuinn, Richard W. Sabo
and Richard F. Syron, directors.


          The Manager manages each Fund's portfolio of investments in accordance
with the stated policies of the Fund, subject to the approval of the Company's
Board. The Manager is responsible for investment decisions, and provides the
Funds with portfolio managers who are authorized by the Company's Board to
execute purchases and sales of securities. The Funds' portfolio managers are
Bernard W. Kiernan, Jr., Patricia A. Larkin and Thomas Riordan. The Manager also
maintains a research department with a professional staff of securities analysts
who provide research services for the Funds and for other funds advised by the
Manager.

          The Manager's Code of Ethics subjects its employees' personal
securities transactions to various restrictions to ensure that such trading does
not disadvantage any fund advised by the Manager. In that regard, portfolio
managers and other investment personnel of the Manager must preclear and report
their personal securities transactions and holdings, which are reviewed for
compliance with the Code of Ethics, and are also subject to the oversight of
Mellon's Investment Ethics Committee. Portfolio managers and other investment
personnel who comply with the Code of Ethic's preclearance and disclosure
procedures and the requirements of the Committee, may be permitted to purchase,
sell or hold securities which also may be or are held in fund(s) they manage or
for which they otherwise provide investment advice.

          The Manager maintains office facilities on behalf of the Company and
furnishes statistical and research data, clerical help, accounting, data
processing, bookkeeping and internal auditing and certain other required
services to the Company. The Manager may pay the Distributor for shareholder
services from the Manager's own assets, including past profits but not including
the management fee paid by the Funds. The Distributor may use part or all of
such payments to pay securities dealers, banks or other financial institutions
in respect of these services. The Manager also may make such advertising and
promotional expenditures, using its own resources, as it from time to time deems
appropriate.

          All expenses incurred in the operation of the Company are borne by the
Manager, except the management fee, taxes, interest, brokerage fees and
commissions, if any, fees and expenses of non-interested Board members, fees and
expenses of independent counsel to the Company and to the non-interested Board
members, and any extraordinary expenses.

          As compensation for the Manager's services, the Company has agreed to
pay the Manager a monthly fee at the annual rate of 0.10% of the value of each
Fund's average daily net assets. All fees and expenses are accrued daily and
deducted before declaration of dividends to shareholders. The Manager has agreed
to reduce its management fee in an amount equal to the accrued fees and expenses
of the non-interested Board members, and the fees and expenses of independent
counsel to the Company and to the non-interested Board members. The management
fees paid by Dreyfus Institutional Preferred Money Market Fund to the Manager
for the period June 11, 1997 (commencement of operations) through March 31, 1998
and the fiscal years ended March 31, 1999 and 2000, amounted to $853,116,
$1,722,571 and $2,576,727, respectively. Dreyfus Institutional Preferred Plus
Money Market Fund had not commenced operations as of the date of this Statement
of Additional Information.

          The aggregate of the fees payable to the Manager is not subject to
reduction as the value of the Funds' net assets increases.

          DISTRIBUTOR. The Distributor, a wholly-owned subsidiary of the Manager
located at 200 Park Avenue, New York, New York 10166, serves as each Fund's
distributor on a best efforts basis pursuant to an agreement with the Company
which is renewable annually.

          TRANSFER AND DIVIDEND DISBURSING AGENT AND CUSTODIAN. Dreyfus
Transfer, Inc. (the "Transfer Agent"), a wholly-owned subsidiary of the Manager,
P.O. Box 9671, Providence, Rhode Island 02940-9671, is the Company's transfer
and dividend disbursing agent. Under a transfer agency agreement with the
Company, the Transfer Agent arranges for the maintenance of shareholder account
records for each Fund, the handling of certain communications between
shareholders and the Fund and the payment of dividends and distributions payable
by the Fund. For these services, the Transfer Agent receives a monthly fee
computed on the basis of the number of shareholder accounts it maintains for
each Fund during the month, and is reimbursed for certain out-of-pocket
expenses.

          The Bank of New York (the "Custodian"), 100 Church Street, New York,
New York 10286, is each Fund's custodian. The Custodian has no part in
determining the investment policies of the Funds or which securities are to be
purchased or sold by the Funds. Under a custody agreement with the Company, the
Custodian holds each Fund's securities and keeps all necessary accounts and
records.


                                HOW TO BUY SHARES


          Each Fund is designed for institutional investors, particularly
colleges and universities for the investment of endowment and other funds. Fund
shares will not be sold to institutions which desire to use the Funds as
commercial sweep accounts.

          The minimum initial investment is $1 billion, unless the investor has
invested at least $1 billion in one Fund, in which case there wold be no minimum
initial investment amount for the other Fund, or the investor has, in the
opinion of Dreyfus Institutional Services Division, a division of the
Distributor, adequate intent and availability of funds to reach a future
aggregate level of investment of $1 billion in the Funds. There is no minimum
for subsequent purchases. The initial investment must be accompanied by the
Account Application. Share certificates are issued only upon the investor's
written request. No certificates are issued for fractional shares. The Company
reserves the right to reject any purchase order.

          Fund shares are sold on a continuous basis at the net asset value per
share next determined after an order in proper form and Federal Funds (monies of
member banks in the Federal Reserve System which are held on deposit at a
Federal Reserve Bank) are received by the Custodian or by any agent or entity
subject to the direction of such agents. If an investor does not remit Federal
Funds, its payment must be converted into Federal Funds. This usually occurs
within one business day of receipt of a bank wire and within two business days
of receipt of a check drawn on a member bank of the Federal Reserve System.
Checks drawn on banks which are not members of the Federal Reserve System may
take considerably longer to convert into Federal Funds. Prior to receipt of
Federal Funds, the investor's money will not be invested.


          Each Fund's net asset value per share is determined as of 5:00 p.m.,
New York time, on each day the New York Stock Exchange or the Transfer Agent is
open for business. Net asset value per share is computed by dividing the value
of the Fund's net assets (i.e., the value of its assets less liabilities) by the
total number of the Fund's shares outstanding. See "Determination of Net Asset
Value."

          Investors whose orders are placed and payments are received in or
converted into Federal Funds by the Custodian by 12:00 Noon, New York time, will
become effective at the price determined at 5:00 p.m., New York time, and will
receive the dividend declared on such day. Except as described below, investors
whose payments are received in or converted into Federal Funds after 12:00 Noon,
New York time, by the Custodian, will begin to accrue dividends on the following
business day.

          Orders in proper form received by Dreyfus Institutional Services
Division in New York after 12:00 Noon, New York time, but prior to 5:00 p.m.,
New York time, and payments for which are received by the Custodian by 6:00
p.m., New York time, will become effective at the price determined at 5:00 p.m.,
New York time, and the shares so purchased will receive the dividend declared on
such day.


          USING FEDERAL FUNDS. The Transfer Agent or the Company may attempt to
notify the investor upon receipt of checks drawn on banks that are not members
of the Federal Reserve System as to the possible delay in conversion into
Federal Funds and may attempt to arrange for a better means of transmitting the
money.


                              HOW TO REDEEM SHARES


          WIRE REDEMPTION PRIVILEGE. By using this privilege, the investor
authorizes the Transfer Agent to act on wire, telephone or letter redemption
instructions from any person representing himself or herself to be an authorized
representative of the investor, and reasonably believed by the Transfer Agent to
be genuine. Ordinarily, the Company will initiate payment for shares redeemed
pursuant to this privilege on the same business day if Dreyfus Institutional
Services Division receives the redemption request in proper form in New York by
5:00 p.m., New York time; otherwise the Company will initiate payment on the
next business day. Redemption proceeds will be transferred by Federal Reserve
wire only to a bank that is a member of the Federal Reserve System.


          Investors with access to telegraphic equipment may wire redemption
requests to the Transfer Agent by employing the following transmittal code which
may be used for domestic or overseas transmission:

                                                 Transfer Agent's
         TRANSMITTAL CODE                        ANSWER BACK SIGN
         ----------------                        ----------------
                144295                           144295 TSSG PREP

          Investors who do not have direct access to telegraphic equipment may
have the wire transmitted by contacting a TRT Cables operator at 1-800-654-7171,
toll free. Investors should advise the operator that the above transmittal code
must be used and should inform the operator of the Transfer Agent's answer back
sign.


          The Company reserves the right to refuse any request made by wire or
telephone and may limit the amount involved or the number of telephone
redemptions. This procedure may be modified or terminated at any time by the
Transfer Agent or the Company. Shares for which certificates have been issued
may not be redeemed by wire or telephone.

          REDEMPTION THROUGH COMPATIBLE AUTOMATED FACILITIES. Each Fund makes
available to institutions the ability to redeem shares through a compatible
automated interface or trading system. Investors desiring to redeem shares in
this manner should call Dreyfus Institutional Services Division at one of the
telephone numbers listed on the cover of this Statement of Additional
Information to determine whether their automated facilities are compatible and
to receive instructions for redeeming shares in this manner.

          REDEMPTION COMMITMENT. The Company has committed to pay in cash all
redemption requests by any shareholders of record, limited in amount during any
90-day period to the lesser of $250,000 or 1% of the value of a Fund's net
assets at the beginning of such period. Such commitment is irrevocable without
the prior approval of the Securities and Exchange Commission. In the case of
requests for redemption in excess of such amount, the Company's Board reserves
the right to make payments in whole or in part in securities or other assets of
the Fund in case of an emergency or any time a cash distribution would impair
the liquidity of the Fund to the detriment of the existing shareholders. In such
event, the securities would be valued in the same manner as the Fund's portfolio
is valued. If the recipient sells such securities, brokerage charges might be
incurred.

          SUSPENSION OF REDEMPTIONS. The right of redemption may be suspended or
the date of payment postponed (a) during any period when the New York Stock
Exchange is closed (other than customary weekend and holiday closings), (b) when
trading in the markets the relevant Fund ordinarily utilizes is restricted, or
when an emergency exists as determined by the Securities and Exchange Commission
so that disposal of the Fund's investments or determination of its net asset
value is not reasonably practicable, or (c) for such other periods as the
Securities and Exchange Commission by order may permit to protect the Fund's
investors.


                        DETERMINATION OF NET ASSET VALUE


          AMORTIZED COST PRICING. The valuation of each Fund's portfolio
securities is based upon their amortized cost which does not take into account
unrealized capital gains or losses. This involves valuing an instrument at its
cost and thereafter assuming a constant amortization to maturity of any discount
or premium, regardless of the impact of fluctuating interest rates on the market
value of the instrument. While this method provides certainty in valuation, it
may result in periods during which value, as determined by amortized cost, is
higher or lower than the price the Fund would receive if it sold the instrument.

          The Company's Board has established, as a particular responsibility
within the overall duty of care owed to each Fund's investors, procedures
reasonably designed to stabilize each Fund's price per share as computed for the
purpose of purchases and redemptions at $1.00. Such procedures include review of
each Fund's portfolio holdings by the Company's Board, at such intervals as it
deems appropriate, to determine whether the Fund's net asset value per share
calculated by using available market quotations or market equivalents deviates
from $1.00 per share based on amortized cost. In such review, investments for
which market quotations are readily available will be valued at the most recent
bid price or yield equivalent for such securities or for securities of
comparable maturity, quality and type, as obtained from one or more of the major
market makers for the securities to be valued. Other investments and assets will
be valued at fair value as determined in good faith by the Company's' Board.

          The extent of any deviation between a Fund's net asset value based
upon available market quotations or market equivalents and $1.00 per share based
on amortized cost will be examined by the Company's Board. If such deviation
exceeds 1/2%, the Company's Board will consider promptly what action, if any,
will be initiated. In the event the Company's Board determines that a deviation
exists which may result in material dilution or other unfair results to
investors or existing shareholders, it has agreed to take such corrective action
as it regards as necessary and appropriate including: selling portfolio
instruments prior to maturity to realize capital gains or losses or to shorten
average portfolio maturity; withholding dividends or paying distributions from
capital or capital gains; redeeming shares in kind; or establishing a net asset
value by using available market quotations or market equivalents.

          NEW YORK STOCK EXCHANGE AND TRANSFER AGENT CLOSINGS. The following are
the holidays (as observed) on which both the New York Stock Exchange and the
Transfer Agent currently are closed: New Year's Day, Martin Luther King Jr. Day,
Presidents' Day, Memorial Day, Independence Day, Labor Day, Thanksgiving and
Christmas. The New York Stock Exchange also is closed on Good Friday.

                              SHAREHOLDER SERVICES

          FUND EXCHANGES. Shares of one Fund may be exchanged for shares of the
other Fund. To request an exchange, exchange instructions must be given in
writing or by telephone. By using the Telephone Exchange Privilege, the investor
authorizes the Transfer Agent to act on exchange instructions from any person
representing himself or herself to be an authorized representative of the
investor and reasonably believed by the Transfer Agent to be genuine. Telephone
exchanges may be subject to limitations as to the amount involved or the number
of telephone exchanges permitted. Shares will be exchanged at the net asset
value next determined after receipt of an exchange request in proper form.
Shares in certificate form are not eligible for telephone exchange.

          No fees currently are charged shareholders directly in connection with
exchanges, although the Company reserves the right, upon not less than 60 days'
written notice, to charge shareholders a nominal administrative fee in
accordance with rules promulgated by the Securities and Exchange Commission.

          DREYFUS AUTO-EXCHANGE PRIVILEGE. Dreyfus Auto-Exchange Privilege
permits an investor to purchase, in exchange for shares of one Fund, shares of
the other Fund if the investor is a shareholder in such other Fund. This
Privilege is available only for existing accounts. Shares will be exchanged on
the basis of relative net asset value. Enrollment in or modification or
cancellation of this Privilege is effective three business days following
notification by the investor. An investor will be notified if its account falls
below the amount designated under this Privilege. In this case, an investor's
account will fall to zero unless additional investments are made in excess of
the designated amount prior to the next Auto-Exchange transaction. Shares in
certificate form are not eligible for this Privilege.

          Fund Exchanges and the Dreyfus Auto-Exchange Privilege are available
to investors resident in any state in which shares of the Fund being acquired
may legally be sold. Shares may be exchanged only between accounts having
identical names and other identifying designations.

          The Company reserves the right to reject any exchange request in whole
or in part. The availability of Fund Exchanges or the Dreyfus Auto-Exchange
Privilege may be modified or terminated at any time upon notice to investors.


                       DIVIDENDS, DISTRIBUTIONS AND TAXES


          Management believes that Dreyfus Institutional Preferred Money Market
Fund has qualified for the fiscal year ended March 31, 2000 as a "regulated
investment company" under the Internal Revenue Code of 1986, as amended (the
"Code"). It is expected that Dreyfus Institutional Preferred Plus Money Market
Fund will qualify as a regulated investment company under the Code. Each Fund
intends to continue to so qualify if such qualification is in the best interests
of its shareholders. Such qualification relieves the Fund of any liability for
Federal income tax to the extent its earnings are distributed in accordance with
applicable provisions of the Code. If a Fund did not qualify as a regulated
investment company, it would be treated for tax purposes as an ordinary
corporation subject to Federal income tax.

          Each Fund ordinarily declares dividends from net investment income on
each day the New York Stock Exchange or the Transfer Agent is open for business.
Each Fund's earnings for Saturdays, Sundays and holidays are declared as
dividends on the preceding business day. Dividends usually are paid on the last
calendar day of each month, and automatically are reinvested in additional
shares of the Fund at net asset value or, at the investor's option, paid in
cash. If an investor redeems all shares in its account at any time during the
month, all dividends to which the investor is entitled are paid along with the
proceeds of the redemption.

          Ordinarily, gains and losses realized from portfolio transactions will
be treated as capital gain or loss. However, all or a portion of any gain
realized from the sale or other disposition of certain market discount bonds
will be treated as ordinary income.


                             PORTFOLIO TRANSACTIONS


          Portfolio securities ordinarily are purchased directly from the issuer
or from an underwriter or a market maker for the securities. Usually no
brokerage commissions will be paid by the Funds for such purchases. Purchases
from underwriters of portfolio securities may include a concession paid by the
issuer to the underwriter and the purchase price paid to, and sales price
received from, market makers for the securities may reflect the spread between
the bid and asked price.

          Transactions will be allocated to various dealers by the Funds'
portfolio managers in their best judgment. The primary consideration will be
prompt and effective execution of orders at the most favorable price. Subject to
that primary consideration, dealers may be selected for research, statistical or
other services to enable the Manager to supplement its own research and analysis
with the views and information of other securities firms and may be selected
based upon their sales of share of the Funds or other funds advised by the
Manager or its affiliates.

          Research services furnished by brokers through which the Funds will
effect securities transactions may be used by the Manager in advising other
funds it advises and, conversely, research services furnished to the Manager by
brokers in connection with other funds the Manager advises may be used by the
Manager in advising the Funds. Although it is not possible to place a dollar
value on these services, it is the opinion of the Manager that the receipt and
study of such services should not reduce the overall expenses of its research
department.


                                YIELD INFORMATION


          For the seven-day period ended March 31, 2000, Dreyfus Institutional
Preferred Money Market Fund's yield and effective yield were 6.02% and 6.20%,
respectively. Dreyfus Institutional Preferred Plus Money Market Fund had not
commenced operations as of the date of this Statement of Additional Information.


          Yield is computed in accordance with a standardized method which
involves determining the net change in the value of a hypothetical pre-existing
fund account having a balance of one share at the beginning of a seven calendar
day period for which yield is to be quoted, dividing the net change by the value
of the account at the beginning of the period to obtain the base period return,
and annualizing the results (i.e., multiplying the base period return by 365/7).
The net change in the value of the account reflects the value of additional
shares purchased with dividends declared on the original share and any such
additional shares and fees that may be charged to the shareholder's account, in
proportion to the length of the base period and the fund's average account size,
but does not include realized gains and losses or unrealized appreciation and
depreciation. Effective yield is computed by adding 1 to the base period return
(calculated as described above), raising that sum to a power equal to 365
divided by 7, and subtracting 1 from the result.


          Yields will fluctuate and are not necessarily representative of future
results. Each investor should remember that yield is a function of the type and
quality of the instruments in the portfolio, portfolio maturity and operating
expenses. An investor's principal in a Fund is not guaranteed. See
"Determination of Net Asset Value" for a discussion of the manner in which each
Fund's price per share is determined.

          Comparative performance information may be used from time to time in
advertising or marketing the Funds' shares, including data from Lipper
Analytical Services, Inc., Bank Rate Monitor(TM), IBC's Money Fund Report(TM),
Morningstar, Inc. and other industry publications.

          In early 1974, the Manager commenced offering the first money market
fund to be widely offered on a retail basis, Dreyfus Liquid Assets, Inc. Money
market mutual funds have subsequently grown into a trillion dollar industry.
Currently, the Manager manages approximately $55 billion in money market fund
assets, including approximately $43 billion in money market funds designed for
institutional investors.

                   INFORMATION ABOUT THE COMPANY AND THE FUNDS


          Each Fund share has one vote and, when issued and paid for in
accordance with the terms of the offering, is fully paid and nonassessable. Fund
shares are of one class and have equal rights as to dividends and in
liquidation. Shares have no preemptive, subscription or conversion rights, and
are freely transferable.


          The Company is organized as an unincorporated business trust under the
laws of the Commonwealth of Massachusetts. Under Massachusetts law, shareholders
of a Fund could, under certain circumstances, be held personally liable for the
obligations of that Fund. However, the Company's Agreement and Declaration of
Trust (the "Trust Agreement") disclaims shareholder liability for acts or
obligations of the Company and requires that notice of such disclaimer be given
in the agreement, obligation or instrument entered into or executed by the
Company or a Board member. The Trust Agreement provides for indemnification from
the Fund's property for all losses and expenses of any shareholder held
personally liable for the obligations of the Fund. Thus, the risk of a
shareholder incurring financial loss on account of a shareholder liability is
limited to circumstances in which the Fund itself would be unable to meet its
obligations, a possibility which management believes is remote. Upon payment of
any liability incurred by a Fund, the shareholder paying such liability will be
entitled to reimbursement from the general assets of the Fund. The Company
intends to conduct its operations in a way so as to avoid, as far as possible,
ultimate liability of the shareholders for liabilities of the Funds.

          The Company is a "series fund," which is a mutual fund divided into
separate portfolios, each of which is treated as a separate entity for certain
matters under the 1940 Act and for other purposes. A shareholder of one
portfolio is not deemed to be a shareholder of any other portfolio. For certain
matters shareholders vote together as a group; as to others they vote separately
by portfolio.

          To date, the Board has authorized the creation of two series of
shares. All consideration received by the Company for shares of a series, and
all assets in which such consideration is invested, will belong to that series
(subject only to the rights of creditors of the Company) and will be subject to
the liabilities related thereto. The income attributable to, and the expenses
of, a series will be treated separately from those of the other series. The
Company has the ability to create, from time to time, new series without
shareholder approval.

          Rule 18f-2 under the 1940 Act provides that any matter required to be
submitted under the provisions of the 1940 Act or applicable state law or
otherwise to the holders of the outstanding voting securities of an investment
company, such as the Company, will not be deemed to have been effectively acted
upon unless approved by the holders of a majority of the outstanding shares of
each series affected by such matter. Rule 18f-2 further provides that a series
shall be deemed to be affected by a matter unless it is clear that the interests
of each series in the matter are identical or that the matter does not affect
any interest of such series. However, the Rule exempts the selection of
independent accountants and the election of Board members from the separate
voting requirements of the Rule.

          Unless otherwise required by the 1940 Act, ordinarily it will not be
necessary for the Company to hold annual meetings of shareholders. As a result,
shareholders may not consider each year the election of Board members or the
appointment of auditors. However, the holders of at least 10% of the shares
outstanding and entitled to vote may require the Company to hold a special
meeting of shareholders for purposes of removing a Board member from office.
Shareholders may remove a Board member by the affirmative vote of two-thirds of
the Company's outstanding voting shares. In addition, the Board will call a
meeting of shareholders for the purpose of electing Board members if, at any
time, less than a majority of the Board members then holding office have been
elected by shareholders.

          Each Fund will send annual and semi-annual financial statements to all
its shareholders.


                        COUNSEL AND INDEPENDENT AUDITORS


          Stroock & Stroock & Lavan LLP, 180 Maiden Lane, New York, New York
10038-4982, as counsel for the Company, has rendered its opinion as to certain
legal matters regarding the due authorization and valid issuance of the shares
being sold pursuant to the Funds' Prospectus.

          ______________________________________________________, independent
auditors, have been selected as independent auditors of the Company.

                                    APPENDIX

          Descriptions of the highest commercial paper, bond and other short-
and long-term rating categories assigned by Standard & Poor's Ratings Group
("S&P"), Moody's Investors Service, Inc. ("Moody's"), Fitch IBCA, Inc.
("Fitch"), Duff & Phelps Credit Rating Co. ("Duff") and Thomson BankWatch, Inc.
("BankWatch"):

COMMERCIAL PAPER RATINGS AND SHORT-TERM RATINGS

          The designation A-1 by S&P indicates that the degree of safety
regarding timely payment is either overwhelming or very strong. Those issues
determined to possess overwhelming safety characteristics are denoted with a
plus sign (+) designation.

          The rating Prime-1 (P-1) is the highest commercial paper rating
assigned by Moody's. Issuers of P-1 paper must have a superior capacity for
repayment of short-term promissory obligations, and ordinarily will be evidenced
by leading market positions in well established industries, high rates of return
on funds employed, conservative capitalization structures with moderate reliance
on debt and ample asset protection, broad margins in earnings coverage of fixed
financial charges and high internal cash generation, and well established access
to a range of financial markets and assured sources of alternate liquidity.

          The rating Fitch-1 (Highest Grade) is the highest commercial paper
rating assigned by Fitch. Paper rated Fitch-1 is regarded as having the
strongest degree of assurance for timely payment.

          The rating Duff-1 is the highest commercial paper rating assigned by
Duff. Paper rated Duff-1 is regarded as having very high certainty of timely
payment with excellent liquidity factors which are supported by ample asset
protection. Risk factors are minor.

          The rating TBW-1 is the highest short-term obligation rating assigned
by BankWatch. Obligations rated TBW-1 are regarded as having the strongest
capacity for timely repayment.

BOND RATINGS AND LONG-TERM RATINGS

          Bonds rated AAA are considered by S&P to be the highest grade
obligation and possess an extremely strong capacity to pay principal and
interest.

          Bonds rated Aaa are judged by Moody's to be of the best quality. Bonds
rated Aa by Moody's are judged by Moody's to be of high quality by all standards
and, together with the Aaa group, they comprise what are generally known as
high-grade bonds.

          Bonds rated AAA by Fitch are judged by Fitch to be strictly high
grade, broadly marketable and suitable for investment by trustees and fiduciary
institutions and liable to but slight market fluctuation other than through
changes in the money rate. The prime feature of an AAA bond is a showing of
earnings several times or many times interest requirements, with such stability
of applicable earnings that safety is beyond reasonable question whatever
changes occur in conditions.

          Bonds rated AAA by Duff are considered to be of the highest credit
quality. The risk factors are negligible, being only slightly more than U.S.
Treasury debt.

          Obligations rated AAA by IBCA have the lowest expectation of
investment risk. Capacity for timely repayment of principal and interest is
substantial, such that adverse changes in business, economic or financial
conditions are unlikely to increase investment risk significantly. Obligations
rated AA by IBCA have a very low expectation of investment risk. Capacity for
timely repayment of principal and interest is substantial. Adverse changes in
business, economic or financial conditions may increase investment risk albeit
not very significantly.

          IBCA also assigns a rating to certain international and U.S. banks. An
IBCA bank rating represents IBCA's current assessment of the strength of the
bank and whether such bank would receive support should it experience
difficulties. In its assessment of a bank, IBCA uses a dual rating system
comprised of Legal Ratings and Individual Ratings. In addition, IBCA assigns
banks long- and short-term ratings as used in the corporate ratings discussed
above. Legal Ratings, which range in gradation from 1 through 5, address the
question of whether the bank would receive support provided by central banks or
shareholders if it experienced difficulties, and such ratings are considered by
IBCA to be a prime factor in its assessment of credit risk. Individual Ratings,
which range in gradations from A through E, represent IBCA's assessment of a
bank's economic merits and address the question of how the bank would be viewed
if it were entirely independent and could not rely on support from state
authorities or its owners.

          In addition to ratings of short-term obligations, BankWatch assigns a
rating to each issuer it rates, in gradations of A through E. BankWatch examines
all segments of the organization including, where applicable, the holding
company, member banks or associations, and other subsidiaries. In those
instances where financial disclosure is incomplete or untimely, a qualified
rating (QR) is assigned to the institution. BankWatch also assigns, in the case
of foreign banks, a country rating which represents an assessment of the overall
political and economic stability of the country in which the bank is domiciled.

          Not Applicable

ITEM 25.  INDEMNIFICATION
-------   ---------------

          Reference is made to Article EIGHTH of the Registrant's Amended and
          Restated Declaration of Trust, filed as Exhibit 1 to Pre-Effective
          Amendment No. 1. The application of these provisions is limited by
          Article 10 of the Registrant's By-laws, filed as Exhibit 2 to
          Pre-Effective Amendment No. 1, and by the following undertaking set
          forth in the rules promulgated by the Securities and Exchange
          Commission.

          Insofar as indemnification for liabilities arising under the
          Securities Act of 1933 may be permitted to trustees, officers and
          controlling persons of the registrant pursuant to the foregoing
          provisions, or otherwise, the registrant has been advised that in the
          opinion of the Securities and Exchange Commission such indemnification
          is against public policy as expressed in such Act and is, therefore,
          unenforceable. In the event that a claim for indemnification against
          such liabilities (other than the payment by the registrant of expenses
          incurred or paid by a trustee, officer or controlling person of the
          registrant in the successful defense of any action, suit or
          proceeding) is asserted by such trustee, officer or controlling person
          in connection with the securities being registered, the registrant
          will, unless in the opinion of its counsel the matter has been settled
          by a controlling precedent, submit to a court of appropriate
          jurisdiction the question whether such indemnification by it is
          against public policy as expressed in such Act and will be governed by
          the final adjudication of such issue.

          Reference is also made to the Distribution Agreement filed as Exhibit
          (e) to Post-Effective Amendment No. 5.

ITEM 26.  BUSINESS AND OTHER CONNECTONS OF INVESTMENT ADVISER.
-------   ---------------------------------------------------

          The Dreyfus Corporation ("Dreyfus") and subsidiary companies comprise
          a financial service organization whose business consists primarily of
          providing investment management services as the investment adviser and
          manager for sponsored investment companies registered under the
          Investment Company Act of 1940 and as an investment adviser to
          institutional and individual accounts. Dreyfus also serves as
          sub-investment adviser to and/or administrator of other investment
          companies. Dreyfus Service Corporation, a wholly-owned subsidiary of
          Dreyfus, serves primarily as a registered broker-dealer and
          distributor of other investment companies advised and administered by
          Dreyfus. Dreyfus Investment Advisors, Inc., another wholly-owned
          subsidiary, provides investment management services to various pension
          plans, institutions and individuals.
