Funds at a Glance

          Each of the Funds described in this prospectus is a money
          market fund. Money market funds must follow strict rules about
          the quality, maturity and other features of securities they
          purchase. The Funds also try to maintain a share price of
          $1.00 while paying income to shareholders. However, no money
          market fund guarantees that you will receive your money back.

          Each Fund has its own goals and investment strategies, and
          each offers a different mix of investments. Of course, there
          is no assurance that any Fund will achieve its investment
          goals.

CitiFunds Institutional
Liquid Reserves

          This summary briefly describes CitiFunds Institutional Liquid
          Reserves and the principal risks of investing in it. Only
          Class A shares are offered by this prospectus. For more
          information, see MORE ABOUT THE FUNDS on page 34.

          FUND GOAL

          The Fund's goal is to provide shareholders with liquidity and
          as high a level of current income as is consistent with
          preservation of capital. Of course, there is no assurance that
          the Fund will achieve its goal.

          MAIN INVESTMENT STRATEGIES

          CitiFunds Institutional Liquid Reserves invests only in high
          quality, short-term money market instruments denominated in
          U.S. dollars. These may include:

            o obligations of U.S. and non-U.S. banks;

            o commercial paper and asset backed securities;

            o short-term obligations of the U.S. government and its
              agencies and instrumentalities, and repurchase agreements for
              these obligations; and

            o obligations issued or guaranteed by the governments of
              Western Europe, Australia, Japan and Canada.

          The Fund invests at least 25%, and may invest up to 100%, of
          its assets in bank obligations, such as certificates of
          deposit, fixed time deposits and bankers' acceptances.

          Please note that the Fund invests in securities through an
          underlying mutual fund.

          MAIN RISKS

          Investing in a mutual fund involves risk. Although CitiFunds
          Institutional Liquid Reserves seeks to preserve the value of
          your investment at $1.00 per share, it is possible to lose
          money by investing in this Fund. Please remember that an
          investment in the Fund is not a deposit of Citibank and is not
          insured or guaranteed by the Federal Deposit Insurance
          Corporation or any other government agency.

          The principal risks of investing in the Fund are described
          below. Please note that there are many other factors that
          could adversely affect your investment, and that could prevent
          the Fund from achieving its goals, which are not described
          here. More information about risks appears in the Funds'
          Statement of Additional Information. Before investing, you
          should carefully consider the risks that you will assume.

          YIELD FLUCTUATION. The Fund invests in short term money market
          instruments. As a result, the amount of income paid to you by
          the Fund will go up or down depending on day-to-day variations
          in short term interest rates. Investing in high quality,
          short-term instruments may result in a lower yield (the income
          on your investment) than investing in lower quality or longer-
          term instruments.

          CREDIT RISK. The Fund invests in debt securities that are
          rated, when the Fund buys them, in the highest short term
          rating category by nationally recognized rating agencies or,
          in Citibank's opinion, are of comparable quality. However, it
          is possible that some issuers will be unable to make the
          required payments on debt securities held by the Fund. Debt
          securities also go up or down in value based on the perceived
          creditworthiness of issuers. A default on an investment held
          by the Fund could cause the value of your investment in the
          Fund to decline.

          INTEREST RATE AND MARKET RISK. A major change in interest
          rates or a significant decline in the market value of a Fund
          investment, or other market event could cause the value of
          your investment in the Fund, or its yield, to decline.

          FOREIGN SECURITIES. You should be aware that investments in
          foreign securities involve risks relating to political, social
          and economic developments abroad, as well as risks resulting
          from the differences between the regulations to which U.S. and
          non-U.S. issuers and markets are subject. These risks may
          include expropriation of assets, confiscatory taxation,
          withholding taxes on dividends and interest paid on fund
          investments, fluctuations in currency exchange rates, currency
          exchange controls and other limitations on the use or transfer
          of assets by the Fund or issuers of securities, and political
          or social instability. In addition, foreign companies may not
          be subject to accounting standards or governmental supervision
          comparable to U.S. companies, and there may be less public
          information about their operations. Foreign markets may be
          less liquid and more volatile than U.S. markets. As a result,
          there may be rapid changes in the value of foreign securities.
          Foreign markets also may offer less protection to investors
          such as the Fund.

          CONCENTRATION IN THE BANKING INDUSTRY. CitiFunds Institutional
          Liquid Reserves concentrates in bank obligations. This means
          that an investment in the Fund is particularly susceptible to
          adverse events affecting the banking industry. Banks are
          highly regulated. Decisions by regulators may limit the loans
          banks make and the interest rates and fees they charge, and
          may reduce bank profitability. Banks also depend on being able
          to obtain funds at reasonable costs to finance their lending
          operations. This makes them sensitive to changes in money
          market and general economic conditions. When a bank's
          borrowers get in financial trouble, their failure to repay the
          bank will also affect the bank's financial situation.

          $1.00 NET ASSET VALUE. In order to maintain a $1.00 per share
          net asset value, the Fund could reduce the number of its
          outstanding shares. The Fund could do this if there were a
          default on an investment held by the Fund, or if the
          investment declined significantly in value. If this happened,
          you would own fewer shares. By investing in the Fund, you
          agree to this reduction should it become necessary.

Fund Performance

          The following bar chart and table can help you evaluate the
          risks and performance of the Fund. The bar chart shows the
          Fund's total returns for the calendar years indicated. The
          table compares the average annual returns for the Fund's Class
          A shares to the performance of the IBC Financial Data 1st Tier
          Institutional Money Market Funds Average. When you consider
          this information, please remember that the Fund's past
          performance is not necessarily an indication of how it will
          perform in the future. The Fund's performance reflects certain
          fee waivers or reimbursements. If these are reduced or
          eliminated, the Fund's performance may go down. For current
          yield information, please call 800-625-4554 toll free, or

          EXAMPLE

          This example is intended to help you compare the cost of
          investing in the Fund to the cost of investing in other mutual
          funds. The example assumes that:

            o you invest $10,000 in the Fund for the time periods
              indicated;

            o you reinvest all dividends;

            o you then sell all of your shares at the end of those periods;

            o your investment has a 5% return each year -- the assumption
              of a 5% return is required by the SEC for the purpose of this
              example and is not a prediction of the Fund's future
              performance; and

            o the operating expenses as shown in the table remain the same
              -- the example includes contractual fee waivers for the one
              year period, but does not include voluntary waivers and fee
              reimbursements.

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

CitiFunds Institutional
U.S. Treasury Reserves

          This summary briefly describes CitiFunds Institutional U.S.
          Treasury Reserves and the principal risks of investing in it.
          For more information, see MORE ABOUT THE FUNDS on page 34.

          FUND GOAL

          The Fund's goal is to provide its shareholders with liquidity
          and as high a level of current income from U.S. government
          obligations as is consistent with the preservation of capital.
          Of course, there is no assurance that the Fund will achieve
          its goal.

          MAIN INVESTMENT STRATEGIES

          Institutional U.S. Treasury Reserves may invest in:

            o U.S. Treasury bills, notes and bonds;

            o Treasury receipts; and

            o securities issued by U.S. government agencies and
              instrumentalities that are backed by the full faith and
              credit of the U.S. government.

          Please note that the Fund invests in securities through an
          underlying mutual fund.

          MAIN RISKS

          Investing in a mutual fund involves risk. Although CitiFunds
          Institutional U.S. Treasury Reserves seeks to preserve the
          value of your investment at $1.00 per share, it is possible to
          lose money by investing in this Fund. Please remember that an
          investment in the Fund is not a deposit of Citibank and is not
          insured or guaranteed by the Federal Deposit Insurance
          Corporation or any other government agency.

          The principal risks of investing in the Fund are described
          below. Please note that there are many other factors that
          could adversely affect your investment, and that could prevent
          the Fund from achieving its goals, which are not described
          here. More information about risks appears in the Fund's
          Statement of Additional Information. Before investing, you
          should carefully consider the risks that you will assume.

          YIELD FLUCTUATION.  The Fund invests in short term money
          market instruments. As a result, the amount of income paid to
          you by the Fund will go up or down depending on day-to-day
          variations in short term interest rates. Investing in high
          quality, short-term instruments may result in a lower yield
          (the income on your investment) than investing in lower
          quality or longer-term instruments.

          INTEREST RATE AND MARKET RISK. A major change in interest
          rates or a significant decline in the market value of a Fund
          investment, or other market event could cause the value of
          your investment in the Fund, or its yield, to decline.

          $1.00 NET ASSET VALUE.  In order to maintain a $1.00 per share
          net asset value, the Fund could reduce the number of its
          outstanding shares. The Fund could do this if there were a
          default on an investment held by the Fund, or if the
          investment declined significantly in value. If this happened,
          you would own fewer shares. By investing in the Fund, you
          agree to this reduction should it become necessary.

          risks and performance of the Fund. The bar chart shows the
          Fund's total returns for the calendar years indicated. The

          performance of the IBC Financial Data Institutional 100% U.S.
          Treasury Rated Money Market Funds Average. When you consider
          this information, please remember that the Fund's past
          performance is not necessarily an indication of how the Fund
          will perform in the future. The Fund's performance reflects
          certain fee waivers or reimbursements. If these are reduced or
          eliminated, the Fund's performance may go down. For current

  * In addition to the contractual fee waivers which terminate on
    December 31, 2000, certain of the Fund's service providers are
    voluntarily waiving fees or reimbursing expenses such that
    current net annual operating expenses are:                      0.25%

    These voluntary fee waivers and reimbursements may be reduced or terminated
    at any time. The Fund's service providers will consider renewal of the
    contractual arrangements each year.

          EXAMPLE

          This example is intended to help you compare the cost of
          investing in the Fund to the cost of investing in other mutual
          funds. The example assumes that:

            o you invest $10,000 in the Fund for the time periods
              indicated;

            o you reinvest all dividends;

            o you then sell all of your shares at the end of those periods;

            o your investment has a 5% return each year -- the assumption
              of a 5% return is required by the SEC for the purpose of this
              example and is not a prediction of the Fund's future
              performance; and

            o the Fund's operating expenses as shown in the table remain
              the same -- the example includes contractual fee waivers for
              the one year period, but does not include voluntary waivers
              and fee reimbursements.

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

CitiFunds Institutional
Tax Free Reserves

          This summary briefly describes CitiFunds Institutional Tax
          Free Reserves and the principal risks of investing in it. For
          more information, see MORE ABOUT THE FUNDS on page 34.

          FUND GOALS

          The Fund's goals are to provide its shareholders with high
          levels of current income exempt from federal income taxes,
          preservation of capital and liquidity. Of course, there is no
          assurance that the Fund will achieve its goals.

          MAIN INVESTMENT STRATEGIES

            o Under normal market conditions, Institutional Tax Free
              Reserves invests at least 80% of its assets in high quality
              municipal obligations and in participation interests in these
              obligations issued by banks, insurance companies and other
              financial institutions. Municipal obligations are debt
              securities issued by states, cities and towns and other
              public entities or qualifying issuers. The interest paid on
              these debt securities is free from federal income tax but is
              generally lower than the interest paid on taxable securities.

            o The Fund invests at least 25% of its assets in participation
              interests in municipal obligations that are secured by bank
              letters of credit or guarantees.

            o The Fund may invest up to 20% of its assets in high quality
              securities that pay interest that is subject to federal
              income tax or federal alternative minimum tax.

          Please note that the Fund invests in securities through an
          underlying mutual fund.

          MAIN RISKS

          Investing in a mutual fund involves risk. Although CitiFunds
          Institutional Tax Free Reserves seeks to preserve the value of
          your investment at $1.00 per share, it is possible to lose
          money by investing in this Fund. Please remember that an
          investment in the Fund is not a deposit of Citibank and is not
          insured or guaranteed by the Federal Deposit Insurance
          Corporation or any other government agency.

          The principal risks of investing in the Fund are described
          below. Please note that there are many other factors that
          could adversely affect your investment, and that could prevent
          the Fund from achieving its goals, which are not described
          here. More information about risks appears in the Funds'
          Statement of Additional Information. Before investing, you
          should carefully consider the risks that you will assume.

          YIELD FLUCTUATION.  The Fund invests in short term money
          market instruments. As a result, the amount of income paid to
          you by the Fund will go up or down depending on day-to-day
          variations in short term interest rates. Investing in high
          quality, short-term instruments may result in a lower yield
          (the income on your investment) than investing in lower
          quality or longer-term instruments.

          CREDIT RISK. The Fund invests in high quality debt securities,
          meaning securities that are rated, when the Fund buys them, in
          one of the two highest short term rating categories by
          nationally recognized rating agencies or, in Citibank's
          opinion, are of comparable quality. However, it is possible
          that some issuers will be unable to make the required payments
          on debt securities held by the Fund. Debt securities also go
          up or down in value based on the perceived creditworthiness of
          issuers. A default on an investment held by the Fund could
          cause the value of your investment in the Fund to decline.

          INTEREST RATE AND MARKET RISK. A major change in interest
          rates or a significant decline in the market value of a Fund
          investment, or other market event could cause the value of
          your investment in the Fund, or its yield, to decline.

          NON-DIVERSIFIED STATUS. CitiFunds Instutitional Tax Free
          Reserves is a non-diversified mutual fund. This means that it
          may invest a relatively high percentage of its assets in the
          obligations of a limited number of issuers. Institutional Tax
          Free Reserves also may invest 25% or more of its assets in
          securities of issuers that are located in the same state, that
          derive income from similar type projects or that are otherwise
          related. As a result, many securities held by the Fund may be
          adversely affected by a particular single economic, business,
          regulatory or political event. You should consider the
          potential risk inherent in these policies when you compare the
          Fund with a more diversified mutual fund.

          CONCENTRATION IN THE BANKING INDUSTRY. CitiFunds Instutitional
          Tax Free Reserves concentrates in participation interests in
          municipal obligations that are issued by banks and secured by
          bank letters of credit or guarantees. This means that an
          investment in the Fund is particularly susceptible to adverse
          events affecting the banking industry. Banks are highly
          regulated. Decisions by regulators may limit the loans banks
          make and the interest rates and fees they charge, and may
          reduce bank profitability. Banks also depend on being able to
          obtain funds at reasonable costs to finance their lending
          operations. This makes them sensitive to changes in money
          market and general economic conditions. When a bank's
          borrowers get in financial trouble, their failure to repay the
          bank will also affect the bank's financial situation.

          $1.00 NET ASSET VALUE. In order to maintain a $1.00 per share
          net asset value, the Fund could reduce the number of its
          outstanding shares. The Fund could do this if there were a
          default on an investment held by the Fund, or if the
          investment declined significantly in value. If this happened,
          you would own fewer shares. By investing in the Fund, you
          agree to this reduction should it become necessary.

Fund Performance

          The following bar chart and table can help you evaluate the
          risks and performance of the Fund. The bar chart shows the
          Fund's total returns for the calendar year indicated. The
          table compares the average annual returns for the Fund to the
          performance of the IBC Institutional Tax Free Money Funds
          Average. When you consider this information, please remember
          that the Fund's past performance is not necessarily an
          indication of how it will perform in the future. The Fund's
          performance reflects certain fee waivers or reimbursements. If
          these are reduced or eliminated, the Fund's performance may go
          down. For current yield information, please call 800-625-4554

          EXAMPLE

          This example is intended to help you compare the cost of
          investing in the Fund to the cost of investing in other mutual
          funds. The example assumes that:

            o you invest $10,000 in the Fund for the time periods
              indicated;

            o you reinvest all dividends;

            o you sell all of your shares at the end of those periods;

            o your investment has a 5% return each year -- the assumption
              of a 5% return is required by the SEC for the purpose of this
              example and is not a prediction of the Fund's future
              performance; and

            o the Fund's operating expenses as shown in the table remain
              the same -- the example includes contractual fee waivers for
              the one year period, but does not include voluntary waivers
              and fee reimbursements.

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

          HOW TO BUY SHARES

          Shares of the Funds are offered continuously and purchases may
          be made Monday through Friday, except on certain holidays.
          Shares may be purchased from the Funds' distributor or a
          broker-dealer or financial institution that has an agreement
          with the distributor. You must be a customer of a Shareholder
          Servicing Agent to purchase shares. Shareholder Servicing
          Agents are financial institutions that have entered into
          shareholder servicing agreements concerning the Funds. You pay
          no sales charge (load) to invest in the Funds. Each Fund and
          its distributor have the right to reject any purchase order or
          cease offering Fund shares at any time.

          Shares are purchased at net asset value (normally $1.00 per
          share) the next time it is calculated after your order is
          received and accepted by the distributor.

          Your Shareholder Servicing Agent will not transmit your
          purchase order for Fund shares until it receives the purchase
          price in federal or other immediately available funds. If you
          pay by check, the Shareholder Servicing Agent transmits the
          order when the check clears, usually within two business days.

          If you hold your shares through a Shareholder Servicing Agent,
          your Shareholder Servicing Agent will establish and maintain
          your account and be the shareholder of record. If you wish to
          transfer your account, you may only transfer it to another
          financial institution that acts as a Shareholder Servicing
          Agent, or you may set up an account directly with the Fund's
          transfer agent.

          CitiFunds Institutional Liquid Reserves offers two classes of
          shares, each with different shareholder servicing and
          distribution arrangements and fees. Only Class A shares are
          offered by this prospectus.

          HOW THE PRICE OF YOUR SHARES IS CALCULATED

          Each Fund calculates its net asset value (NAV) every day the
          New York Stock Exchange is open for trading. Institutional
          Liquid Reserves calculates its NAV at 3:00 p.m. Eastern time,
          and the other Funds calculate their NAVs at 12:00 noon Eastern
          time. On days when the financial markets in which the Funds
          invest close early, NAV may be calculated as of the earlier
          close of those markets. The Funds' securities are valued at
          amortized cost, which is approximately equal to market value.

          HOW TO SELL SHARES

          You may sell your shares on any business day. The price will
          be the NAV (normally $1.00 per share) the next time it is
          calculated after your redemption request has been received by
          your Shareholder Servicing Agent. You may contact your
          Shareholder Servicing Agent in writing or, if your Shareholder
          Servicing Agent permits, by telephone. All redemption requests
          must be in proper form, as determined by your Shareholder
          Servicing Agent.

          You will receive your redemption proceeds in federal funds
          normally on the business day on which you sell your shares but
          in any event within seven days. Your redemption proceeds may
          be delayed for up to ten days if your purchase was made by
          check. Your redemption proceeds may also be delayed, or your
          right to receive redemption proceeds suspended, if the New
          York Stock Exchange is closed (other than on weekends or
          holidays) or trading is restricted, or if an emergency exists.
          The Funds have the right to pay your redemption proceeds by
          giving you securities instead of cash. In that case, you may
          incur costs (such as brokerage commissions) converting the
          securities into cash. You should be aware that you may have to
          pay taxes on your redemption proceeds.

          Your Shareholder Servicing Agent may impose a minimum account
          balance requirement. If so, your Shareholder Servicing Agent
          reserves the right to close your account if it falls below the
          required minimum balance. You will have 60 days to make an
          additional investment. If you do not increase your balance,
          your Shareholder Servicing Agent may close your account and
          send the proceeds to you. Your shares will be sold at net
          asset value (normally $1.00 per share) on the day your account
          was closed. Please consult your Shareholder Servicing Agent
          for more information.

          EXCHANGES

          You may exchange your shares of the Funds for shares of
          certain CitiFunds or other funds managed by Citibank. Your
          Shareholder Servicing Agent can provide you with more
          information, including a prospectus for any fund to be
          acquired through an exchange. If your account application
          allows, you may arrange the exchange by telephone.

          Generally, there is no sales charge on shares you get through
          an exchange. However, if you are exchanging shares of a Fund
          for shares of another fund that are subject to an initial
          sales charge, and if the initial sales charge for the shares
          being exchanged into is greater than the sales charge, if any,
          you paid to acquire the Fund shares being exchanged, you will
          have to pay an initial sales charge at a rate equal to the
          difference.

          If you exchange your shares of a Fund for shares subject to an
          initial sales charge, you may qualify for reduction or
          elimination of the sales charge if you meet any of the
          following conditions:

            o You held the Fund shares being exchanged as of January 4,
              1999.

            o The Fund shares being exchanged were purchased with a sales
              charge or acquired through a previous exchange from shares
              purchased with a sales charge.

            o The Fund shares being exchanged represent capital
              appreciation or the reinvestment of dividends or capital
              gains distributions.

          To qualify for this reduction or elimination of the sales
          charge, you must notify your Shareholder Servicing Agent at
          the time of exchange. You may need to provide documentation to
          confirm your entitlement to the sales charge reduction or
          elimination.

          The exchange privilege may be changed or terminated at any
          time. You should be aware that you may have to pay taxes on
          your exchange.

          DIVIDENDS

          Each Fund calculates its net income each business day when it
          calculates its NAV, and declares dividends for all of its
          shareholders of record. Shares begin to accrue dividends on
          the day they are purchased. You will not receive dividends for
          the day on which you redeem your shares. Dividends are
          distributed once a month, on or before the last business day
          of the month. Unless you choose to receive your dividends in
          cash, you will receive them as full and fractional additional
          Fund shares.

          TAX MATTERS

          This discussion of taxes is for general information only. You
          should consult your own tax adviser about your particular
          situation.

          TAXATION OF DISTRIBUTIONS: For Institutional Liquid Reserves
          and Institutional U.S. Treasury Reserves, you normally will
          have to pay federal income tax on any distributions you
          receive from a Fund, whether you take distributions in cash or
          reinvest them in shares. Distributions designated as capital
          gain dividends are taxable as long-term capital gains. Other
          distributions are generally taxable as ordinary income. Some
          dividends paid in January may be taxable as if they had been
          paid the previous December.

          For Institutional Tax Free Reserves, the Fund expects that
          most of its net income will be attributable to interest on
          municipal obligations. As a result most of the Fund's
          dividends to you will not be subject to federal income tax.
          However, the Fund may invest from time to time in taxable
          securities, and certain Fund dividends may be subject to the
          federal alternative minimum tax. It is also possible, but not
          intended, that the Fund may realize short-term or long-term
          capital gains or losses. As a result, the Fund may designate
          some distributions as income or short-term capital gain
          dividends, generally taxable to you as ordinary income, or
          capital gains dividends, taxable to you as long-term capital
          gains, whether you take distributions in cash or reinvest them
          in additional shares.

          Fund dividends which Institutional Tax Free Reserves
          designates as not taxable are taken into account in
          determining the amount of your social security and railroad
          retirement benefits, if any, that may be subject to federal
          income tax. In addition, you may not claim a deduction for
          interest on indebtedness you incurred or continued for the
          purpose of owning Fund shares. Shareholders who are, or who
          are related to, "substantial users" of facilities financed by
          private activity bonds should consult their tax advisers
          before buying Fund shares.

          STATE AND LOCAL TAXES: Generally, you will have to pay state
          or local taxes on Fund dividends and other distributions,
          although distributions derived from interest on U.S.
          government obligations may be exempt from certain state and
          local taxes. Fund dividends that are not taxable to you for
          federal income tax purposes may still be taxable to you under
          the income or other tax laws of any state or local taxing
          authority.

          TAXATION OF TRANSACTIONS: If you sell your shares of a Fund,
          or exchange them for shares of another fund, it is considered
          a taxable event. Depending on your purchase price and the
          sales price of the shares you sell or exchange, you may have a
          gain or loss on the transaction. You are responsible for any
          tax liabilities generated by your transaction.

          BACKUP WITHHOLDING: The account application asks each new
          investor to certify that the investor's Social Security or
          taxpayer identification number is correct and that the
          shareholder is not subject to 31% backup withholding for
          failing to report income to the IRS. A Fund may be required to
          withhold (and pay over to the IRS for your credit) 31% of
          certain distributions it pays you if you fail to provide this
          information or otherwise violate IRS regulations.

          FOREIGN SHAREHOLDERS: Each Fund will withhold U.S. federal
          income tax payments at the rate of 30% (or any lower
          applicable treaty rate) on taxable dividends and other
          payments subject to withholding taxes that are made to persons
          who are not citizens or residents of the United States.
          Distributions received from a Fund by non-U.S. persons also
          may be subject to tax under the laws of their own
          jurisdictions.

Management of the Funds

          INVESTMENT ADVISER

          Each Fund draws on the strength and experience of Citibank.
          Citibank is the investment adviser of each Fund, and subject
          to policies set by the Funds' Trustees, Citibank makes
          investment decisions. Citibank has been managing money since
          1822. With its affiliates, it currently manages more than $351
          billion in assets worldwide.

          Citibank, with its headquarters at 153 East 53rd Street, New
          York, New York, is a wholly-owned subsidiary of Citigroup Inc.
          "CitiFunds" is a service mark of Citicorp.

          Citibank and its affiliates may have banking and investment
          banking relationships with the issuers of securities that are
          held in the Funds. However, in making investment decisions for
          the Funds, Citibank does not obtain or use material inside
          information acquired by any division, department or affiliate
          of Citibank in the course of those relationships. Citibank and
          its affiliates may have loans outstanding that are repaid with
          proceeds of securities purchased by the Funds.

          ADVISORY FEES

          For the Funds' fiscal year ended August 31, 1999 Citibank
          received the following fees:

- --------------------------------------------------------------------------------
                                              Fee, as percentage of average
  Fund                                       daily net assets, after waivers
 ...............................................................................
  INSTITUTIONAL LIQUID RESERVES -- CLASS A                 0.08%
 ...............................................................................
  INSTITUTIONAL U.S. TREASURY RESERVES                     0.07%
 ...............................................................................
  INSTITUTIONAL TAX FREE RESERVES                          0.11%
- --------------------------------------------------------------------------------

          DISTRIBUTION ARRANGEMENTS

          The Funds do not charge any sales loads, deferred sales loads
          or other fees in connection with the purchase of shares.

          The Funds have adopted distribution plans under rule 12b-1
          under the Investment Company Act of 1940. The plans allow
          Institutional U.S. Treasury Reserves, Institutional Tax Free
          Reserves and the Class A shares of Institutional Liquid
          Reserves to use up to 0.10% per year of its average daily net
          assets to compensate the Funds' distributor for its
          distribution activities. Because fees under the plans are paid
          out of Fund assets, over time these fees will increase the
          cost of your investment and may cost you more than paying
          other types of sales charges. The distributor currently waives
          a portion of these fees on a voluntary basis. This fee waiver
          may be terminated or reduced at any time.

          The distributor may make payments for distribution and/or
          shareholder servicing activities out of its past profits and
          other available sources. The distributor may also make
          payments for marketing, promotional or related expenses to
          dealers. The amount of these payments is determined by the
          distributor and may vary. Citibank may make similar payments
          under similar arrangements.

More About the Funds

          The Funds' goals, principal investments and risks are
          summarized in FUNDS AT A GLANCE. More information on
          investments and investment strategies appears below.

          PRINCIPAL INVESTMENT STRATEGIES

          The Funds' principal investment strategies are the strategies
          that, in the opinion of Citibank, are most likely to be
          important in trying to achieve each Fund's investment goals.
          Of course, there can be no assurance that any Fund will
          achieve its goals. Please note that each Fund may also use
          strategies and invest in securities that are not described
          below but that are described in the Statement of Additional
          Information. A Fund may not use all of the strategies and
          techniques or invest in all of the types of securities
          described in the Prospectus or in the Statement of Additional
          Information.

          Each Fund has specific investment policies and procedures
          designed to maintain a constant net asset value of $1.00 per
          share. Each Fund also complies with industry regulations that
          apply to money market funds. These regulations require that
          each Fund's investments mature or be deemed to mature within
          397 days from the date purchased and that the average maturity
          of each Fund's investments (on a dollar-weighted basis) be 90
          days or less. In addition, all of the Funds' investments must
          be in U.S. dollar-denominated high quality securities which
          have been determined by Citibank to present minimal credit
          risks. To be high quality, a security (or its issuer) must be
          rated in one of the two highest short-term rating categories
          by nationally recognized rating agencies, such as Moody's or
          Standard & Poor's, or, in Citibank's opinion, be of comparable
          quality. Investors should note that within these two rating
          categories there may be sub-categories or gradations
          indicating relative quality. If the credit quality of a
          security deteriorates after a Fund buys it, Citibank will
          decide whether the security should be held or sold.

- --------------------------------------------------------------------------------
          WHAT ARE MONEY MARKET INSTRUMENTS?
          A MONEY MARKET INSTRUMENT is a short-term IOU issued by banks
          or other corporations, or the U.S. or a foreign government and
          state or local governments. Money market instruments have
          maturity dates of 13 months or less. Money market instruments
          may include CERTIFICATES OF DEPOSIT, BANKERS' ACCEPTANCES,
          VARIABLE RATE DEMAND NOTES (where the interest rate is reset
          periodically and the holder may demand payment from the issuer
          at any time), FIXED-TERM OBLIGATIONS, COMMERCIAL PAPER (short
          term unsecured debt of corporations), ASSET-BACKED SECURITIES
          (which are backed by pools of accounts receivable such as car
          installment loans or credit card receivables) and REPURCHASE
          AGREEMENTS. In a repurchase agreement, the seller sells a
          security and agrees to buy it back at a later date (usually
          within seven days) and at a higher price, which reflects an
          agreed upon interest rate.
- --------------------------------------------------------------------------------

          CitiFunds Institutional Liquid Reserves invests in high
          quality U.S. dollar-denominated money market instruments of
          U.S. and non-U.S. issuers. These obligations include U.S.
          government obligations, obligations of U.S. and non-U.S.
          banks, obligations issued or guaranteed by the governments of
          Western Europe, Australia, Japan and Canada, commercial paper,
          asset backed securities and repurchase agreements. The Fund's
          U.S. government obligations may include U.S. Treasury bills,
          bonds and notes and obligations of U.S. government agencies
          and instrumentalities that may, but need not, be backed by the
          full faith and credit of the United States. While the Fund can
          invest in all of these types of obligations, the Fund invests
          at least 25% of its assets, and may invest all of its assets
          in bank obligations, including certificates of deposit, fixed
          time deposits and bankers' acceptances. Except for this
          concentration policy, the Fund's investment goals and policies
          may be changed without a shareholder vote.

          CitiFunds Institutional Liquid Reserves invests only in "first
          tier" securities. These securities are rated in the highest
          short-term rating category by nationally recognized rating
          agencies or, in Citibank's opinion, are of comparable quality.

          CitiFunds Institutional U.S. Treasury Reserves invests in U.S.
          Treasury bills, bonds, notes and receipts. Treasury receipts
          are interest coupons on other U.S. Treasury obligations. This
          Fund may also invest in short-term obligations of U.S.
          government agencies and instrumentalities, but only if the
          obligations are backed by the full faith and credit of the
          United States. The Fund's investment goals and policies may be
          changed without a shareholder vote. ALTHOUGH THE FUND INVESTS
          IN U.S. GOVERNMENT OBLIGATIONS, AN INVESTMENT IN THE FUND IS
          NEITHER INSURED NOR GUARANTEED BY THE U.S. GOVERNMENT.

          CitiFunds Institutional Tax Free Reserves invests primarily in
          high quality municipal obligations, including municipal money
          market instruments, and in participation interests in
          municipal obligations. Under normal market conditions, the
          Fund invests at least 80% of its assets in municipal
          obligations and participation interests. This policy cannot be
          changed without a shareholder vote.

          Municipal obligations bought by the Fund must be rated in the
          highest two rating categories of nationally recognized rating
          agencies or determined by Citibank to be of comparable
          quality.

- --------------------------------------------------------------------------------
          WHAT ARE MUNICIPAL OBLIGATIONS?
          Municipal obligations are fixed and variable rate obligations
          issued by or on behalf of states and municipal governments,
          Puerto Rico and other U.S. territories, and their authorities,
          agencies, instrumentalities and political subdivisions, and by
          other qualifying issuers. The interest on these obligations is
          exempt from federal income tax.

          Longer term municipal obligations (municipal bonds) generally
          are issued to raise funds for construction or to retire
          previous debt. Short term obligations (municipal notes or
          commercial paper) may be issued to finance short term cash
          needs in anticipation of receipt of tax and other revenues.
- --------------------------------------------------------------------------------

          CitiFunds Institutional Tax Free Reserves may invest in both
          "general obligation" securities, which are backed by the full
          faith, credit and taxing power of the issuer, and in "revenue"
          securities, which are payable only from revenues from a
          specific project or another revenue source. The Fund also may
          invest in private activity bonds, which fund privately
          operated industrial facilities. Payment on these bonds
          generally is made from payments by the operators of the
          facilities and is not backed by the taxing authority of the
          issuing municipality. The Fund may invest in municipal lease
          obligations, which are undivided interests issued by a state
          or municipality in a lease or installment purchase which
          generally relates to equipment or facilities. In some cases
          payments under municipal leases do not have to be made unless
          money is specifically approved for that purpose by an
          appropriate legislative body.

          CitiFunds Institutional Tax Free Reserves may purchase
          municipal obligations under arrangements (called stand-by
          commitments) where it can sell the securities at an agreed-
          upon price and date under certain circumstances. The Fund can
          also purchase securities under arrangements (called when-
          issued or forward-delivery basis) where the securities will
          not be delivered immediately. The Fund will set aside the
          assets to pay for these securities at the time of the
          agreement.

          CitiFunds Institutional Tax Free Reserves concentrates in
          participation interests issued by banks and other financial
          institutions and secured by bank letters of credit or
          guarantees. This means that the Fund will invest more than 25%
          of its assets in participation interests backed by banks. In a
          participation interest, the bank sells undivided interests in
          a municipal obligation it owns. These interests may be
          supported by a bank letter of credit or guarantee. The
          interest rate generally is adjusted periodically, and the
          holder can sell back to the issuer after a specified notice
          period. If interest rates rise or fall, the rates on
          participation interests and other variable rate instruments
          generally will be readjusted.

          CitiFunds Institutional Tax Free Reserves may also invest in
          taxable money market instruments, particularly if the after-
          tax return on those securities is greater than the return on
          municipal money market instruments. The Fund's taxable
          investments will be comparable in quality to their municipal
          investments. Under normal circumstances, not more than 20% of
          the Fund's assets are invested in taxable instruments. Except
          for its policy to invest in municipal obligations, the Fund's
          investment goals and policies may be changed without a
          shareholder vote.

          CitiFunds Institutional Tax Free Reserves may, from time to
          time, take temporary defensive positions that are inconsistent
          with the Fund's principal investment strategies in attempting
          to respond to adverse market, political or other conditions.
          When doing so, the Fund may invest without limit in high
          quality taxable money market instruments, and may not be
          pursuing its investment objectives.

          INVESTMENT STRUCTURE. The Funds do not invest directly in
          securities but instead invest through an underlying mutual
          fund having the same goals and strategies. Unless otherwise
          indicated, references to these Funds in this Prospectus
          include the underlying fund. Each Fund may stop investing in
          its corresponding underlying fund at any time, and will do so
          if the Fund's Trustees believe that to be in the shareholders'
          best interests. The Fund could then invest in another mutual
          fund or pooled investment vehicle, or could invest directly in
          securities.

          MANAGEMENT STYLE. Managers of mutual funds use different
          styles when selecting securities to purchase. Citibank's
          portfolio managers use a "top-down" approach when selecting
          securities for the Funds. When using a "top-down" approach,
          the portfolio manager looks first at broad economic factors
          and market conditions, such as prevailing and anticipated
          interest rates. On the basis of those factors and conditions,
          the manager selects optimal interest rates and maturities and
          chooses certain sectors or industries within the overall
          market. The manager then looks at individual companies within
          those sectors or industries to select securities for the
          investment portfolio.

          Since the Funds maintain a weighted average maturity of no
          more than 90 days, many of their investments are held until
          maturity. The manager may sell a security before maturity when
          it is necessary to do so to meet redemption requests. The
          manager may also sell a security if the manager believes the
          issuer is no longer as creditworthy, or in order to adjust the
          average weighted maturity of a Fund's portfolio (for example,
          to reflect changes in the manager's expectations concerning
          interest rates), or when the manager believes there is
          superior value in other market sectors or industries.
