LETTER TO OUR SHAREHOLDERS

Dear Shareholder:

The six-month period ended February 28, 1998 was a good one for most financial
assets, especially U.S. stocks and bonds. A remarkably resilient economy, low
rates of inflation and lower interest rates were primarily responsible for the
above-average returns provided by longer-term investments. However, shorter-term
assets -- including money market securities -- did not share the benefits these
positive economic influences provided. As interest rates declined during the
period, so did yields on most money market securities.

   Nonetheless, we are pleased with the performance of CitiFundsSM Institutional
Liquid Reserves. Despite the difficult market environment for short-term
fixed-income securities, the portfolio provided shareholders with a competitive
level of investment income.

   Among other highlights of the reporting period, your Fund has changed its
name to CitiFunds Institutional Liquid Reserves. The Fund's investment objective
and management approach remain the same.

   Finally, we would like to thank you for your continued confidence and
participation.

Sincerely,

/S/ Philip W. Coolidge
    Philip W. Coolidge
    President
    March 20, 1998

PORTFOLIO ENVIRONMENT AND OUTLOOK

SHORT-TERM INTEREST RATES GENERALLY DECLINED OVER THE PAST SIX MONTHS. At the
same time, the U.S. economy continued to grow in the late stages of one of the
longest expansions since World War II. Unlike previous economic cycles, however,
this one has been particularly notable for its persistently low inflation rate.
Inflation has remained benign despite strong economic growth -- about 4% in 1997
- -- and low unemployment.

   A crisis in Emerging Asian markets, where currency devaluations in late
October led to sharp drops in stock and bond markets, provided more reason for
investors and economists to conclude that inflation would not become a problem.
Dramatically lower demand from the region for certain goods and services was
expected to dampen U.S. economic growth and relieve inflation pressures.
Accordingly, the Federal Reserve maintained its monetary policy, neither raising
nor lowering key short-term interest rates. The result: most short-term interest
rates and money market yields declined during the six-month period.

   OUR STRATEGY HAS BEEN TO ATTEMPT TO CAPTURE HIGH YIELDS in this environment
by allocating the fund's assets to those sectors of the market that we believe
provide the most attractive relative values. We look for such opportunities in a
variety of areas, including U.S. Treasury bills, commercial paper, certificates
of deposit, repurchase agreements, fixed-time deposits, bankers' acceptances,
asset-backed securities and floating rate notes.

   We found relatively attractive values in high-quality certificates of deposit
for most of the six-month period. Conversely, the fund had little exposure to
U.S. Treasury bills. We held no short-term securities issued by troubled Asian
financial institutions, enabling us to avoid the problems associated with
economic turmoil in the region.

   In addition, we actively managed the average maturity of the Portfolio in
anticipation of changes in short-term interest rates. As interest rates declined
during the six-month period, we maintained a relatively long average maturity in
order to capture higher yields for as long as possible. However, later in the
period, yields on longer-dated money market securities declined more rapidly
than yields on shorter-dated notes, and opportunities to capture higher yields
were limited using this strategy.

   WE EXPECT YIELDS ON MONEY MARKET SECURITIES TO STAY NEAR OR ONLY SLIGHTLY
BELOW CURRENT LEVELS. If our economic forecast is correct, longer-term interest
rates should decline modestly in response to slower U.S. economic growth. We
believe that the Federal Reserve Board would have little reason to raise
interest rates in a slow-growth environment. In fact, it is possible that the
Federal Reserve might reduce interest rates to stimulate growth if the economy
falters. Therefore, we currently intend to maintain our positions with respect
to the fund's average duration and sector rotation strategies.

   Whatever the next six months hold, we will continue to manage the Portfolio
according to the approach we have followed for years. We intend to adjust the
average maturity in anticipation of changes in interest rates and shift assets
among the sectors of the short-term money market that we believe are most
attractive. We believe that this strategy will provide competitive returns
commensurate with a stable principal value.

The Annualized Current 7-Day Yield reflects the amount of income generated by
the investment during that seven-day period and assumes that the income is
generated each week over a 365 day period. The yield is shown as a percentage of
the investment.

The Effective 7-Day Yield is calculated similarly, but when annualized the
income earned by the investment during that seven-day period is assumed to be
reinvested. The effective yield is slightly higher than the current yield
because of the compounding effect of this assumed reinvestment.

Note: A money market fund's yield more closely reflects the current earnings of
the fund than does the total return.

COMPARISON OF 7-DAY YIELDS FOR CITIFUNDS INSTITUTIONAL LIQUID RESERVES
VS. IBC INSTITUTIONAL TAXABLE MONEY MARKET FUNDS AVERAGE

As illustrated, CitiFunds Institutional Liquid Reserves generally provided a
higher annualized seven-day yield to that of a comparable IBC Money Fund
Average, as published in IBC Money Fund ReportTM, for the one year period.

Note: The Fund seeks to maintain a stable $1.00 per share price, although there
is no assurance that this will be so on a continuing basis. Fund shares are not
insured or guaranteed by the U.S. Government. Yields and total returns will
fluctuate and past performance is no guarantee of future results. Total return
figures include reinvestment of dividends. Returns and yields reflect certain
voluntary fee waivers. If the waivers were not in place, the Fund's returns and
yields would have been lower.

CITIFUNDS INSTITUTIONAL LIQUID RESERVES
NOTES TO FINANCIAL STATEMENTS (Unaudited)

1. SIGNIFICANT ACCOUNTING POLICIES CitiFunds Institutional Liquid Reserves (the
"Fund") is a separate diversified series of CitiFunds Institutional Trust (the
"Trust"), a Massachusetts business trust. Effective January 2, 1998 the Landmark
Institutional Liquid Reserves changed its name to CitiFunds Institutional Liquid
Reserves. The Trust also changed its name from Landmark Institutional Trust to
CitiFunds Institutional Trust. The Trust is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
The Fund invests all of its investable assets in Cash Reserves Portfolio (the
"Portfolio"), a management investment company for which Citibank, N.A.
("Citibank") serves as Investment Adviser. CFBDS, Inc. ("CFBDS"), (formerly
Landmark Funds Broker-Dealer Services, Inc.) acts as the Trust's Administrator
and Distributor. Citibank also serves as Sub-Administrator and makes Fund shares
available to customers as Shareholder Servicing Agents.

   The Trust seeks to achieve the Fund's investment objective to provide
liquidity and as high a level of current income as is consistent with the
preservation of capital by investing all of its investable assets in the
Portfolio, an open-end, diversified management investment company having the
same investment objective as the Fund. The value of such investment reflects the
Fund's proportionate interest (33.5% at February 28, 1998) in the net assets of
the Portfolio.

   The financial statements of the Portfolio, including the portfolio of
investments, are contained elsewhere in this report and should be read in
conjunction with the Fund's financial statements.

   The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.

   The significant accounting policies consistently followed by the Fund are as
follows:

   A. INVESTMENT VALUATION Valuation of securities by the Portfolio is discussed
in Note 1A of the Portfolio's Notes to Financial Statements, which are included
elsewhere in this report.

   B. INVESTMENT INCOME The Fund earns income, net of Portfolio expenses, daily
based on its investment in the Portfolio. 

   C. FEDERAL TAXES The Fund's policy is to comply with the provisions of the
Internal Revenue Code available to regulated investment companies and to
distribute to shareholders all of its taxable income. Accordingly, no provision
for federal income or excise tax is necessary.

   D. EXPENSES The Fund bears all costs of its operations other than expenses
specifically assumed by Citibank and CFBDS. Expenses incurred by the Trust with
respect to any two or more Funds in the series are allocated in proportion to
the average net assets of each fund, except where allocations of direct expenses
to each fund can otherwise be made fairly. Expenses directly attributable to a
fund are charged to that fund. The Fund's share of the Portfolio's expenses are
charged against and reduce the amount of the Fund's investment in the Portfolio.

2. DIVIDENDS The net income of the Fund is determined once daily, as of 3:00
p.m., Eastern time, and all of the net income of the Fund so determined is
declared as a dividend to shareholders of record at the time of such
determination. Dividends are distributed in the form of additional shares of the
Fund or, at the election of the shareholder, in cash (subject to the policies of
the shareholder's Shareholder Servicing Agent) on or prior to the last business
day of the month.

3. ADMINISTRATIVE SERVICES PLAN The Trust has adopted an Administrative Services
Plan which provides that the Trust, on behalf of each Fund, may obtain the
services of an Administrator, one or more Shareholder Servicing Agents, and
other Servicing Agents and may enter into agreements providing for the payment
of fees for such services. Under the Trust's Administrative Services Plan, the
aggregate of the fees paid to the Administrator from the Fund under such Plan
and of the fees paid to the Shareholder Servicing Agents from the Fund may not
exceed 0.45% of the Fund's average daily net assets on an annualized basis for
the Fund's then-current fiscal year.

   A. ADMINISTRATIVE FEES Under the terms of an Administrative Services
Agreement, CFBDS is entitled to an administrative fee from the Fund, as
compensation for overall administrative services and general office facilities,
which is accrued daily and paid monthly at an annual rate of 0.35% of the Fund's
average daily net assets. The Administrative fees amounted to $5,288,268 of
which $4,020,688 was voluntarily waived for the six months ended February 28,
1998. Citibank acts as Sub-Administrator and performs such duties and receives
such compensation from CFBDS as from time to time is agreed to by CFBDS and
Citibank. The Fund pays no compensation directly to any Trustee or to any
officer who is affiliated with the Administrator, all of whom receive
remuneration for their services to the Fund from the Administrator or its
affiliates. Certain of the officers and a Trustee of the Fund are officers and a
director of the Administrator or its affiliates.

   B. SHAREHOLDER SERVICING AGENTS FEES The Trust, on behalf of the Fund, has
entered into shareholder servicing agreements with each Shareholder Servicing
Agent pursuant to which that Shareholder Servicing Agent acts as an agent for
its customers and provides other related services. For their services, each
Shareholder Servicing Agent receives fees from the Fund, which may be paid
periodically, which may not exceed, on an annualized basis, an amount equal to
0.10% of the average daily net assets of the Fund represented by shares owned
during the period for which payment has been made by investors for whom such
Shareholder Servicing Agent maintains a servicing relationship. The Shareholder
Servicing Agents fees amounted to $1,510,934, all of which was voluntarily
waived for the six months ended February 28, 1998.

4. DISTRIBUTION FEES The Trust has adopted a Plan of Distribution pursuant to
Rule 12b-1 under the Investment Company Act of 1940, as amended, in which the
Fund reimburses the Distributor for expenses incurred or anticipated in
connection with the sale of shares of the Fund, at an annual rate not to exceed
0.10% of the Fund's average daily net assets of the Fund. The Distribution fees
amounted to $1,510,934, all of which was voluntarily waived for the six months
ended February 28, 1998. The Distributor has voluntarily agreed to assume all
distribution expenses through February 28, 1998.

5. SHARES OF BENEFICIAL INTEREST The Declaration of Trust permits the Trustees
to issue an unlimited number of full and fractional shares of beneficial
interest ($0.00001 par value).

6. INVESTMENT TRANSACTIONS Increases and decreases in the Fund's investment in
the Portfolio aggregated $7,582,541,953 and $6,742,810,237 respectively, for the
six months ended February 28, 1998.

CASH RESERVES PORTFOLIO
NOTES TO FINANCIAL STATEMENTS (Unaudited)

1. SIGNIFICANT ACCOUNTING POLICIES Cash Reserves Portfolio (the "Portfolio") is
registered under the U.S. Investment Company Act of 1940, as amended, as a
no-load, diversified, open-end management investment company which was organized
as a trust under the laws of the State of New York. The Declaration of Trust
permits the Trustees to issue beneficial interests in the Portfolio. Signature
Financial Group (Grand Cayman), Ltd. ("SFG") acts as the Portfolio's
Administrator and Citibank, N.A. ("Citibank") acts as the Investment Adviser.

   The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.

   The significant accounting policies consistently followed by the Portfolio
are as follows:

   A. Valuation of Investments Money market instruments are valued at amortized
cost, which the Trustees have determined in good faith constitutes fair value.
This method involves valuing a portfolio security at its cost and thereafter
assuming a constant amortization to maturity of any discount or premium. The
Portfolio's use of amortized cost is subject to the Portfolio's compliance with
certain conditions as specified under Rule 2a-7 of the U.S. Investment Company
Act of 1940.

   B. Interest Income and Expenses Interest income consists of interest accrued
and discount earned (including both original issue and market discount) on the
investments of the Portfolio, accrued ratably to the date of maturity, plus or
minus net realized gain or loss, if any, on investments. Expenses of the
Portfolio are accrued daily. The Portfolio bears all costs of its operations
other than expenses specifically assumed by Citibank and SFG.

   C. U.S. Federal Income Taxes The Portfolio is considered a partnership under
the U.S. Internal Revenue Code. Accordingly, no provision for federal income
taxes is necessary.

   D. Repurchase Agreements It is the policy of the Portfolio to require the
custodian bank to take possession, to have legally segregated in the Federal
Reserve Book Entry System or to have segregated within the custodian bank's
vault, all securities held as collateral in support of repurchase agreement
investments. Additionally, procedures have been established by the Portfolio to
monitor, on a daily basis, the market value of the repurchase agreement's
underlying investments to ensure the existence of a proper level of collateral.

   E. Fees Paid Indirectly The Portfolio's custodian bank calculates its fees
based on the Portfolio's average daily net assets. The fees are reduced
according to a fee arrangement, which provides for custody fees to be reduced
based on a formula developed to measure the value of cash deposited with the
custodian by the Portfolio. This amount is shown as a reduction of expenses on
the Statement of Operations.

   F. Other Purchases, maturities and sales of money market instruments are 
accounted for on the date of the transaction.

2. INVESTMENT ADVISORY FEES AND ADMINISTRATIVE FEES
   A. Investment Advisory Fee -- The Investment advisory fees paid to Citibank,
as compensation for overall investment management services, amounted to
$6,618,719, of which $3,040,866 was voluntarily waived for the six months ended
February 28, 1998. The investment advisory fees are computed at an annual rate
of 0.15% of the Portfolio's average daily net assets.

   B. Administrative Fees -- Under the terms of an Administrative Services
Agreement, the administrative fee paid to the Administrator, as compensation for
overall administrative services and general office facilities, are computed at
the annual rate of 0.05% of the Portfolio's average daily net assets. The
Administrative fees amounted to $2,206,240, all of which were voluntarily waived
for the six months ended February 28, 1998. The Portfolio pays no compensation
directly to any Trustee or to any officer who is affiliated with the
Administrator, all of whom receive remuneration for their services to the
Portfolio from the Administrator or its affiliates. Certain of the officers and
a Trustee of the Portfolio are officers and a director of the Administrator or
its affiliates.

3. INVESTMENT TRANSACTIONS Purchases, maturities and sales of money market
instruments aggregated $165,501,676,391 and $164,382,220,872, respectively, for
the six months ended February 28, 1998.

4. LINE OF CREDIT The Portfolio, along with other CitiFunds, entered into an
agreement with a bank which allows the Funds collectively to borrow up to $60
million for temporary or emergency purposes. Interest on borrowings, if any, is
charged to the specific fund executing the borrowing at the base rate of the
bank. The line of credit requires a quarterly payment of a commitment fee based
on the average daily unused portion of the line of credit. For the six months
ended February 28, 1998, the commitment fee allocated to the Portfolio was
$15,151. Since the line of credit was established, there have been no
borrowings.

LETTER TO OUR SHAREHOLDERS
Dear Shareholder:
 
The six-month period ended February 28, 1998 was a good one for most financial
assets, especially U.S. stocks and bonds. A remarkably resilient economy, low
rates of inflation and lower interest rates were primarily responsible for the
above-average returns provided by longer-term investments. However, shorter-term
assets -- including money market securities -- did not share the benefits these
positive economic influences provided. As interest rates declined during the
period, so did yields on most money market securities.

   Nonetheless, we are pleased with the performance of CitiFundsSM Institutional
U.S. Treasury Reserves. Despite the difficult market environment for short-term
fixed-income securities, the portfolio continued to provide shareholders with a
competitive level of investment income from short-term U.S. Treasury securities.

   Among other highlights of the reporting period, your Fund has changed its
name to CitiFunds Institutional U.S. Treasury Reserves. The Fund's investment
objective and management approach remain the same.

   Finally, we would like to thank you for your continued confidence and
participation.
 
    Sincerely,

/s/ PHILIP COOLIDGE 
    Philip W. Coolidge
    President
    March 20, 1998

PORTFOLIO ENVIRONMENT AND OUTLOOK
 
SHORT-TERM INTEREST RATES GENERALLY DECLINED OVER THE PAST SIX MONTHS. At the
same time, the U.S. economy continued to grow in the late stages of one of the
longest expansions since World War II. Unlike previous economic cycles, however,
this one has been particularly notable for its persistently low inflation rate.
Inflation has remained benign despite strong economic growth -- about 4% in
1997 -- and low unemployment.

   A crisis in emerging Asian markets, where currency devaluations in late
October led to sharp drops in stock and bond markets, provided more reason for
investors and economists to conclude that inflation would not soon become a
problem. Dramatically lower demand from Asia for certain goods and services from
multinational companies based in the U.S. was expected to dampen domestic
economic growth and forestall dormant inflation pressures. Accordingly, the
Federal Reserve maintained its monetary policy, neither raising nor lowering key
short-term interest rates.

   OUR STRATEGY HAS BEEN TO ATTEMPT TO MAINTAIN HIGH YIELDS in this environment
by managing the average maturity of the portfolio in anticipation of changes in
short-term interest rates. As interest rates declined, we maintained a
relatively long average maturity in order to capture higher yields for as long
as possible. However, because yields on longer-dated money market securities
declined more rapidly than yields on shorter-dated notes, opportunities to
capture higher yields were limited using this strategy. In addition, to maintain
its AAA rating, the portfolio does not exceed an average maturity of 60 days.

   What's more, yields on U.S. Treasury securities were unusually low relative
to other types of money market securities during the six-month period. This was
primarily a result of the federal government's progress toward balancing its
budget. A strong economy boosted tax revenues at the same time that a
restrictive fiscal policy curbed spending. Because the federal government has
less need to borrow under such conditions, the available supply of U.S. Treasury
bills and notes has become increasingly limited. Yet, demand for these
investments remains high from domestic and overseas investors seeking the
unparalleled credit quality of investments backed by the U.S. government.

   WE EXPECT YIELDS ON MONEY MARKET SECURITIES TO MOVE MODESTLY LOWER. If our
economic forecast is correct, longer-term interest rates should continue to
decline modestly in response to slower U.S. economic growth. We believe that the
Federal Reserve Board would have little reason to raise interest rates in a
slow-growth environment. In fact, it is possible that the Federal Reserve might
reduce key short-term interest rates to stimulate growth if the economy falters.

   Whatever the next six months hold, we will continue to manage the portfolio
according to the approach we have followed for years. We intend to adjust the
average maturity in anticipation of changes in interest rates and shift assets
among the sectors of the short-term money market that we believe are most
attractive. We believe that this strategy will provide competitive returns
commensurate with a stable principal value.

The Annualized Current 7-Day Yield reflects the amount of income generated by
the investment during the seven day period and assumes that the income is
generated each week over a 365 day period. The yield is shown as a percentage of
the investment.
 
The Effective 7-Day Yield is calculated similarly, but when annualized the
income earned by the investment during the seven day period is assumed to be
reinvested. The effective yield is slightly higher than the current yield
because of the compounding effect of this assumed reinvestment.
 
Note: A money market fund's yield more closely reflects the current earnings of
the fund than does the total return.
 
Note: The Fund seeks to maintain a stable $1.00 per share price, although there
is no assurance that this will be so on a continuing basis. Fund shares are not
insured or guaranteed by the U.S. Government. Yields and total returns will
fluctuate and past performance is no guarantee of future results. Total return
figures include reinvestment of dividends. Returns and yields reflect certain
voluntary fee waivers. If the waivers were not in place, the Fund's returns and
yields would have been lower.

CITIFUNDS INSTITUTIONAL U.S. TREASURY RESERVES
NOTES TO FINANCIAL STATEMENTS (Unaudited)
 
1. SIGNIFICANT ACCOUNTING POLICIES CitiFunds Institutional U.S. Treasury
Reserves (the 'Fund') is a diversified separate series of CitiFunds
Institutional Trust (the 'Trust'), a Massachusetts business trust. Effective
January 2, 1998, Landmark U.S. Treasury Reserves changed its name to CitiFunds
Institutional U.S. Treasury Reserves. The Trust also changed its name from
Landmark Institutional Trust to CitiFunds Institutional Trust. The Trust is
registered under the Investment Company Act of 1940, as amended, as an open-end
management investment company. The Fund invests all of its investable assets in
U.S. Treasury Reserves Portfolio (the 'Portfolio'), a management investment
company for which Citibank, N.A. ('Citibank') serves as Investment Adviser.
CFBDS, Inc. ('CFBDS'), (formerly Landmark Funds Broker-Dealer Services, Inc.),
acts as the Trust's Administrator and Distributor. Citibank also serves as
Sub-Administrator and makes shares available to customers through various
Shareholder Servicing Agents.

   The Trust seeks to achieve the Fund's investment objective of providing
shareholders with liquidity and as high a level of current income from U.S.
Government obligations as is consistent with preservation of capital by
investing all of its investable assets in the Portfolio, an open-end,
diversified management investment company having the same investment as the
Fund. The value of such investment reflects the Fund's proportionate interest
(25.9% at February 28, 1998) in the net assets of the Portfolio.

   The financial statements of the Portfolio, including the portfolio of
investments, are contained elsewhere in this report and should be read in
conjunction with the Fund's financial statements.

   The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.

   The significant accounting policies consistently followed by the Fund are in
conformity with generally accepted accounting principles and are as follows:

   A. Investment Income The Fund earns income, net of Portfolio expenses, daily
on its investment in the Portfolio.

   B. Federal Taxes The Fund's policy is to comply with the provisions of the
Internal Revenue Code available to regulated investment companies and to
distribute to shareholders all of its taxable income. Accordingly, no provision
for federal income or excise tax is necessary.

   C. Expenses The Fund bears all costs of its operations other than expenses
specifically assumed by Citibank and CFBDS. Expenses incurred by the Trust with
respect to any two or more Funds in a series are allocated in proportion to the
average net assets of each Fund, except where allocations of direct expenses to
each Fund can otherwise be made fairly. Expenses directly attributable to a Fund
are charged to that Fund.

   D. Other All the net investment income of the Portfolio is allocated pro
rata, based on respective ownership interests, among the Fund and other
investors in the Portfolio at the time of such determination.

   2. DIVIDENDS The net income of the Fund is determined once daily, as of 12:00
noon, Eastern standard time, and all of the net income of the Fund so determined
is declared as a dividend to shareholders of record at the time of such
determination. Dividends are distributed in the form of additional shares of the
Fund or, at the election of the shareholder, in cash (subject to the policies of
the shareholder's Shareholder Servicing Agent) on or prior to the last business
day of the month.

   3. ADMINISTRATIVE SERVICES PLAN The Trust has adopted an Administrative
Services Plan which provides that the Trust, on behalf of each Fund, may obtain
the services of an Administrator, one or more Shareholder Servicing Agents, and
other Servicing Agents and may enter into agreements providing for the payment
of fees for such services. Under the Trust's Administrative Services Plan, the
aggregate of the fee paid to the Administrator from the Fund and of the fees
paid to the Shareholder Servicing Agents from the Fund under such plan may not
exceed 0.45% of the Fund's average daily net assets on an annualized basis for
the Fund's then-current fiscal year.

   A. Administrative Fees Under the terms of an Administrative Services
Agreement, CFBDS is entitled to an administrative fee from the Fund, as
compensation for overall administrative services and general office facilities,
which is accrued daily and paid monthly at the annual rate of 0.35% of the
Fund's average daily net assets. The Administrative fees amounted to $512,191,
of which $348,081 was voluntarily waived for the six months ended February 28,
1998. Citibank acts as Sub-Administrator and performs such duties and receives
such compensation from CFBDS as from time to time is agreed to by CFBDS and
Citibank. The Fund pays no compensation directly to any Trustee or to any
officer who is affiliated with the Administrator, all of whom receive
remuneration for their services to the Fund from the Administrator or its
affiliates. Certain of the officers and a Trustee of the Fund are officers and a
director of the Administrator or its affiliates.

   B. Shareholder Servicing Fees The Trust, on behalf of the Fund, has entered
into shareholder servicing agreements with each Shareholder Servicing Agent
pursuant to which the Shareholder Servicing Agent acts as an agent for its
customers and provides other related services. For their services, each
Shareholder Servicing Agent receives fees from the Fund, which may be paid
periodically, but may not exceed, on an annualized basis, an amount equal to
0.10% of the average daily net assets of the Fund represented by shares owned
during the period for which payment is being made by investors for whom such
Shareholder Servicing Agent maintains a servicing relationship. The Shareholder
Servicing Agent fees amounted to $146,340, all of which was voluntarily waived
for the six months ended February 28, 1998.

   4. DISTRIBUTION FEES The Trust has adopted a Plan of Distribution pursuant to
Rule 12b-1 under the Investment Company Act of 1940, as amended, in which the
Fund reimburses the Distributor for expenses incurred or anticipated in
connection with the sale of shares of the Fund, limited to an annual rate of
0.10% of the average daily net assets of the Fund. The Distribution fees
amounted to $146,340, all of which was voluntarily waived for the six months
ended February 28, 1998.

   5. SHARES OF BENEFICIAL INTEREST The Declaration of Trust permits the
Trustees to issue an unlimited number of full and fractional shares of
beneficial interest ($0.00001 par value).

   6. INVESTMENT TRANSACTIONS Increases and decreases in the Fund's investment
in the Portfolio aggregated $369,043,263 and $475,169,042, respectively, for the
six months ended February 28, 1998.

U.S. TREASURY RESERVES PORTFOLIO
NOTES TO FINANCIAL STATEMENTS (Unaudited)
 
1. SIGNIFICANT ACCOUNTING POLICIES U.S. Treasury Reserves Portfolio (the
'Portfolio') is registered under the Investment Company Act of 1940, as amended,
as a no-load, diversified, open-end management investment company which was
organized as a trust under the laws of the State of New York. The Declaration of
Trust permits the Trustees to issue beneficial interests in the Portfolio. The
Investment Adviser of the Portfolio is Citibank N.A. ('Citibank'). Signature
Financial Group (Grand Cayman), Ltd. ('SFG') acts as the Portfolio's
Administrator.

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.

   The significant accounting policies consistently followed by the Portfolio
are as follows:

   A. Valuation of Investments Money market instruments are valued at amortized
cost, which the Trustees have determined in good faith constitutes fair value.
The Portfolio's use of amortized cost is subject to the Portfolio's compliance
with certain conditions as specified under Rule 2a-7 of the Investment Company
Act of 1940.

   B. Investment Income and Expenses Investment income consists of interest
accrued and discount earned (including both original issue and market discount),
adjusted for amortization of premium, on the investments of the Portfolio,
accrued ratably to the date of maturity, plus or minus net realized gain or
loss, if any, on investments. Expenses of the Portfolio are accrued daily.

   C. Federal Income Taxes The Portfolio's policy is to comply with the
applicable provisions of the Internal Revenue Code. Accordingly, no provision
for federal income taxes is necessary.

   D. Fees Paid Indirectly The Portfolio's custodian bank calculates its fees
based on the Portfolio's average daily net assets. The fee is reduced according
to a fee arrangement, which provides for custody fees to be reduced based on a
formula developed to measure the value of cash deposited with the custodian by
the Portfolio. This amount is shown as a reduction of expenses on the Statement
of Operations.

   E. Other Purchases, maturities and sales of money market instruments are
accounted for on the date of the transaction.
 
   2. INVESTMENT ADVISORY FEES AND ADMINISTRATIVE FEES
   A. Investment Advisory Fee The Investment advisory fees paid to Citibank, as
compensation for overall investment management services, amounted to $655,060,
of which $376,194 was voluntarily waived for the six months ended February 28,
1998. The investment advisory fee is computed at an annual rate of 0.15% of the
Portfolio's average daily net assets.

   B. Administrative Fees Under the terms of an Administrative Services
Agreement, the administrative fee paid to the Administrator, as compensation for
overall administrative services and general office facilities, is accrued daily
and paid monthly at the annual rate of 0.05% of the Portfolio's average daily
net assets. The Administrative fees amounted to $218,353, all of which was
voluntarily waived for the six months ended February 28, 1998. The Portfolio
pays no compensation directly to any Trustee or any officer who is affiliated
with the Administrator, all of whom receive remuneration for their services to
the Portfolio from the Administrator or its affiliates. Certain of the officers
and a Trustee of the Portfolio are officers and a director of the Administrator
or its affiliates.
 
   3. INVESTMENT TRANSACTIONS Purchases, maturities and sales of U.S. Treasury
obligations, aggregated $4,195,145,141 and $4,255,621,845, respectively, for the
six months ended February 28, 1998.
 
   4. LINE OF CREDIT The Portfolio, along with other CitiFunds, entered into an
agreement with a bank which allows the Funds collectively to borrow up to $60
million for temporary or emergency purposes. Interest on borrowings, if any, is
charged to the specific fund executing the borrowing at the base rate of the
bank. The line of credit requires a quarterly payment of a commitment fee based
on the average daily unused portion of the line of credit. For the six months
ended February 28, 1998, the commitment fee allocated to the Portfolio was
$1,664. Since the line of credit was established, there have been no borrowings.

LETTER TO OUR SHAREHOLDERS
Dear Shareholder:
 
The six-month period ended February 28, 1998 was a good one for most financial
assets, especially U.S. stocks and bonds. A remarkably resilient economy, low
rates of inflation and lower interest rates were primarily responsible for the
above-average returns provided by longer-term investments. However, shorter-term
assets did not share the benefits these positive economic influences provided.
As interest rates declined during the period, so did yields on most money market
securities.

   Nonetheless, we are pleased with the performance of CitiFundsSM Institutional
Tax Free Reserves. Despite the difficult market environment for short-term
tax-exempt securities, the portfolio continued to provide shareholders with a
competitive level of income that is largely free from federal income taxes.

   Among other highlights of the reporting period, your portfolio has changed
its name to CitiFunds Institutional Tax Free Reserves. The fund's investment
objective and management approach remain the same.

   Finally, we would like to thank you for your continued confidence and
participation.
 
     Sincerely,
 
/s/  Philip W. Coolidge

     Philip W. Coolidge
     President
     March 20, 1998

PORTFOLIO ENVIRONMENT AND OUTLOOK
 
SHORT-TERM INTEREST RATES GENERALLY DECLINED OVER THE PAST SIX MONTHS. At the
same time, the U.S. economy continued to grow in the late stages of one of the
longest expansions since World War II. Unlike previous economic cycles, however,
this one has been particularly notable for its persistently low inflation rate.
Inflation has remained benign despite strong economic growth and low
unemployment. As a result, fixed-income investors have grown increasingly
confident that inflation will not erode the future value of their principal and
income. They bid up the prices of bonds accordingly, and yields on money market
securities generally fell.

     The tax-exempt bond market also responded during the six-month period to
its own unique influences. While changes in the yields of short-term tax-exempt
securities generally tracked those of comparable taxable securities, supply-and-
demand factors helped keep tax-exempt yields high relative to U.S. Treasury
bills and notes. First, demand for short-term investments was relatively
constrained because the stellar returns provided by stocks and longer-term bonds
provided little incentive for investors to seek the safety of money market
funds. In addition, the possibility of changes in the rules governing corporate
holdings of municipal bonds reduced business demand for tax-exempt securities.
Yet, the available supply of short-term tax-exempt securities rose as
municipalities came to the market to take advantage of low interest rates,
putting upward pressure on rates.

     WE FOUND ATTRACTIVE INVESTMENT OPPORTUNITIES IN VARIABLE-RATE SECURITIES,
which were available with yields up to one percentage point higher than
comparable fixed-rate notes. Consequently, variable-rate notes comprised between
60% and 75% of the portfolio's assets on average during the six-month period.
Many municipalities used variable-rate securities to refinance their longer-term
debt, potentially enabling them to reduce their borrowing costs further if
interest rates continue to decline.

     The portfolio's increased exposure to variable-rate securities caused its
average maturity to decline from about 50 days at the start of the six-month
period to as low as 35 days. Later in the period, we took advantage of technical
factors to purchase longer-dated tax-exempt notes at favorable rates of
interest, and the portfolio's average maturity rose to as much as 60 days. In
our view, our current 'barbell' portfolio structure  --  short-term
variable-rate securities on one end, longer-term fixed-rate notes on the
other  --  positions the portfolio well for the future. If short-term tax-exempt
yields fall further, the longer-dated, fixed-rate holdings should help us
maintain relatively high yields. If interest rates rise, the portfolio's
shorter-term, variable-rate securities should help us participate in higher
yields as they become available.

     WE BELIEVE THAT MODESTLY LOWER SHORT-TERM INTEREST RATES ARE LIKELY.
Ultimately, however, we believe that the direction of tax-exempt money market
yields depends upon the U.S. economy and the nation's stock market. If the
economy slows, yields of short-term tax-exempt and taxable securities will
generally move lower. If slower economic growth causes a stock market
correction, investors may shift their assets to the short-term tax-exempt market
in order to avoid potential losses. In this case, higher demand for tax-exempt
securities may cause yields to decline further.

     Whatever the next six months hold, we will continue to manage the portfolio
according to the approach we have followed for years. We intend to adjust the
average maturity in anticipation of changes in interest rates and shift assets
amount the most attractive sectors of the tax-exempt marketplace. We fully
expect this strategy to provide competitive levels of federally tax-exempt
income commensurate with a stable principal value.

The Annualized Current 7-Day Yield reflects the amount of income generated by
the investment during that seven day period and assumes that the income is
generated each week over a 365 day period. The yield is shown as a percentage of
the investment.
 
The Effective 7-Day Yield is calculated similarly, but when annualized the
income earned by the investment during that seven day period is assumed to be
reinvested. The effective yield is slightly higher than the current yield
because of the compounding effect of this assumed reinvestment.
 
Note: A money market fund's yield more closely reflects the current earnings of
the fund than does the total return.

As illustrated, CitiFunds Institutional Tax Free Reserves provided a similar
annualized seven-day yield to that of a comparable IBC Money Fund Average, as
published in IBC Money Fund Report'tm', for the one year period.
 
Notes: The Fund seeks to maintain a stable $1.00 per share price, although there
is no assurance that this will be so on a continuing basis. Fund shares are not
insured or guaranteed by the U.S. Government. Yields and total returns will
fluctuate and past performance is no guarantee of future results. Total return
figures include reinvestment of dividends. Returns and yields reflect certain
voluntary fee waivers. If the waivers were not in place, the Fund's returns
would have been lower.

CITIFUNDS INSTITUTIONAL TAX FREE RESERVES
NOTES TO FINANCIAL STATEMENTS (Unaudited)
 
1. SIGNIFICANT ACCOUNTING POLICIES CitiFunds Institutional Tax Free Reserves
(the 'Fund') is a separate non-diversified series of CitiFunds Institutional
Trust (the 'Trust'), a Massachusetts business trust. The Trust is registered
under the Investment Company Act of 1940, as amended, as an open-end management
investment company. Effective January 2, 1998 Landmark Institutional Tax Free
Reserves changed its name to CitiFunds Institutional Tax Free Reserves. The
Trust also changed its name from Landmark Institutional Trust to CitiFunds
Institutional Trust. The Fund invests all of its investable assets in Tax Free
Reserves Portfolio (the 'Portfolio'), a management investment company for which
Citibank, N.A. ('Citibank') serves as Investment Adviser.

   CFBDS, Inc. ('CFBDS'), (formerly Landmark Funds Broker-Dealer Services, Inc.)
acts as the Fund's Administrator and Distributor. Citibank also serves as Sub-
Administrator and makes Fund shares available to customers as Shareholder
Servicing Agent.

   The Trust seeks to achieve the Fund's investment objective of a high level of
current income which is exempt from federal income taxes, consistent with
preservation of capital and liquidity, by investing all of its investable assets
in the Portfolio, an open-end, non-diversified management investment company
having the same investment objective as the Fund. The value of such investment
reflects the Fund's proportionate interest (approximately 12.2% at February 28,
1998) in the net assets of the Portfolio.

   The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.

   The financial statements of the Portfolio, including the portfolio of
investments, are contained elsewhere in this report and should be read in
conjunction with the Fund's financial statements.

   The significant accounting policies consistently followed by the Fund are in
conformity with generally accepted accounting principles and are as follows:

   A. Investment Income The Fund earns income, net of Portfolio expenses, daily
on its investment in the Portfolio.

   B. Federal Taxes The Fund's policy is to comply with the provisions of the
Internal Revenue Code available to regulated investment companies and to
distribute to shareholders all of its net investment income. Accordingly, no
provision for federal income or excise tax is necessary. Dividends paid by the
Fund from net interest received on tax-exempt money market instruments are not
includable by shareholders as gross income for federal income tax purposes
because the Fund intends to meet certain requirements of the Internal Revenue
Code applicable to regulated investment companies which will enable the Fund to
pay exempt-interest dividends. The portion of such interest, if any, earned on
private activity bonds issued after August 7, 1986, may be considered a tax
preference item to shareholders.

   C. Expenses The Fund bears all costs of its operations other than expenses
specifically assumed by Citibank and CFBDS.
 
2. DIVIDENDS The net income of the Fund is determined once daily, as of 12:00
noon, Eastern standard time, and all of the net income of the Fund so determined
is declared as a dividend to shareholders of record at the time of such
determination. Dividends are distributed in the form of additional shares of the
Fund or, at the election of the shareholder, in cash (subject to the policies of
the shareholder's Shareholder Servicing Agent) on or prior to the last business
day of the month.
 
3. ADMINISTRATIVE SERVICES PLAN The Fund has adopted an Administrative Services
Plan which provides that the Trust on behalf of each Fund, may obtain the
services of an Administrator, one or more Shareholder Servicing Agents, and
other Servicing Agents, and may enter into agreements providing for the payment
of fees for such services. Under the Trust's Administrative Services Plan, the
aggregate of the fee paid to the Administrator from the Fund and the fees paid
to the Shareholder Servicing Agents from the Fund may not exceed 0.45% of the
Fund's average daily net assets on an annualized basis for the Fund's
then-current fiscal year.

   A. Administrative Fees Under the terms of an Administrative Services
Agreement, CFBDS is entitled to an administrative fee, as compensation for
overall administrative services and general office facilities, which is computed
at the annual rate of 0.35% of the Fund's average daily net assets.
Administrative fees amounted to $91,633, all of which was voluntarily waived for
the six months ended February 28, 1998. Citibank acts as Sub-Administrator and
performs such duties and receives such compensation from CFBDS as from time to
time is agreed to by CFBDS and Citibank. The Fund pays no compensation directly
to any Trustee or any officer who is affiliated with the Administrator, all of
whom receive remuneration for their services to the Fund from the Administrator
or its affiliates. Certain of the officers and a Trustee of the Fund are
officers and a director of the Administrator or its affiliates.

   B. Shareholder Servicing Agent Fees The Trust, on behalf of the Fund, has
entered into shareholder servicing agreements with each Shareholder Servicing
Agent pursuant to which that Shareholder Servicing Agent acts as an agent for
its customers and provides other related services. For their services, each
Shareholder Servicing Agent receives a fee from the Fund, which may be paid
periodically, but may not exceed, on an annualized basis, an amount equal to
0.10% of the average daily net assets of the Fund represented by shares owned
during the period for which payment is being made by investors for whom such
Shareholder Servicing Agent maintains a servicing relationship. The Shareholder
Servicing Agent fees amounted to $26,181, all of which was voluntarily waived
for the six months ended February 28, 1998.
 
   4. DISTRIBUTION FEE The Trust has adopted a Plan of Distribution pursuant to
Rule 12b-1 under the Investment Company Act of 1940, as amended, in which the
Fund reimburses the Distributor for expenses incurred or anticipated in
connection with the sale of shares of the Fund, at an annual rate not to exceed
0.10% of the Fund's average daily net assets of the Fund. The distribution fees
amounted to $26,181, all of which was voluntarily waived for the six months
ended February 28, 1998.
 
   5. SHARE OF BENEFICIAL INTEREST The Declaration of Trust permits the Trustees
to issue an unlimited number of full and fractional Shares of Beneficial
Interest (without par value).
 
   6. INVESTMENT TRANSACTIONS Increases and decreases in the Fund's investment
in the Portfolio aggregated $75,546,297 and $69,587,165, respectively, for the
six months ended February 28, 1998.
 
   7. ASSUMPTION OF EXPENSES CFBDS has voluntarily agreed to pay a portion of
the unwaived expenses of the Fund for the six months ended February 28, 1998,
which amounted to $15,578.

TAX FREE RESERVES PORTFOLIO
NOTES TO FINANCIAL STATEMENTS (Unaudited)

1. SIGNIFICANT ACCOUNTING POLICIES Tax Free Reserves Portfolio (the "Portfolio")
is registered under the Investment Company Act of 1940, as amended, as a
no-load, non-diversified, open-end management investment company which was
organized as a trust under the laws of the State of New York. The Declaration of
Trust permits the Trustees to issue beneficial interests in the Portfolio.
CFBDS, Inc. ("CFBDS"), (formerly Landmark Funds Broker-Dealer Services, Inc.)
acts as the Portfolio's Administrator. Citibank, N.A. ("Citibank") acts as the
Investment Adviser.

   The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.

   The significant accounting policies consistently followed by the Portfolio
are as follows:

   A. Valuation of Investments Money market instruments are valued at amortized
cost, which the Trustees have determined in good faith constitutes fair value.
The Portfolio's use of amortized cost is subject to the Portfolio's compliance
with certain conditions as specified under Rule 2a-7 of the Investment Company
Act of 1940.

   B. Investment Income and Expenses Investment income consists of interest
accrued and discount earned (including both original issue and market discount),
adjusted for amortization of premium, on the investments of the Portfolio.
Expenses of the Portfolio are accrued daily.

   C. Federal Income Taxes The Portfolio's policy is to comply with the
applicable provisions of the Internal Revenue Code. Accordingly, no provision
for federal income taxes is necessary.

   D. Fees Paid Indirectly The Fund's custodian bank calculates its fees based
on the Fund's average daily net assets. The fee is reduced according to a fee
arrangement, which provides for custody fees to be reduced based on a formula
developed to measure the value of cash deposited with the custodian by the Fund.
This amount is shown as a reduction of expenses on the Statement of Operations.

   E. Other Purchases, maturities and sales, of money market instruments are
accounted for on the date of the transaction.

2. INVESTMENT ADVISORY FEE AND ADMINISTRATIVE FEE
   A. Investment Advisory Fee The investment advisory fee paid to Citibank, as
compensation for overall investment management services, amounted to $503,609,
of which $247,504 was voluntarily waived for the six months ended February 28,
1998. The investment advisory fee is computed at the annual rate of 0.20% of the
Portfolio's average daily net assets.

   B. Administrative Fee Under the terms of an Administrative Services
Agreement, the administrative fee payable to the Administrator, as compensation
for overall administrative services and general office facilities, is computed
at the annual rate of 0.05% of the Portfolio's average daily net assets and
amounted to $125,902, all of which was voluntarily waived for the six months
ended February 28, 1998. The Portfolio pays no compensation directly to any
Trustee or any officer who is affiliated with the Administrator, all of whom
receive remuneration for their services to the Portfolio from the Administrator
or its affiliates. Certain of the officers and a Trustee of the Portfolio are
officers and a director of the Administrator or its affiliates. 

3. INVESTMENT TRANSACTIONS Purchases, and maturities and sales of money market
instruments, exclusive of securities purchased subject to repurchase agreements,
aggregated $859,113,045 and $815,200,804, respectively, for the six months ended
February 28, 1998.

4. FEDERAL INCOME TAX BASIS OF INVESTMENT SECURITIES The cost of investment
securities owned at February 28, 1998, for federal income tax purposes, amounted
to $546,218,266.

5. LINE OF CREDIT The Portfolio, along with other CitiFunds, entered into an
agreement with a bank which allows the Funds collectively to borrow up to $60
million for temporary or emergency purposes. Interest on borrowings, if any, is
charged to the specific fund executing the borrowing at the base rate of the
bank. The line of credit requires a quarterly payment of a commitment fee based
on the average daily unused portion of the line of credit. For the six months
ended February 28, 1998, the commitment fee allocated to the Portfolio was $899.
Since the line of credit was established, there have been no borrowings.

LETTER TO OUR SHAREHOLDERS

Dear Shareholder:

The six-month period ended February 28, 1998 was a good one for most financial
assets, especially U.S. stocks and bonds. A remarkably resilient economy, low
rates of inflation and lower interest rates were primarily responsible for the
above-average returns provided by longer-term investments. However, shorter-term
assets did not share the benefits these positive economic influences provided.
As interest rates declined during the period, so did yields on most money market
securities.

   Nonetheless, we are pleased with the performance of CitiFundsSM Institutional
Cash Reserves. Despite the difficult market environment for short-term
fixed-income securities, the portfolio provided shareholders with a competitive
level of investment income while maintaining its Aaa rating by Moody's Investors
Service and AAAm rating by Standard & Poor's.

   Finally, we would like to thank you for your continued confidence and
participation.

    Sincerely,

/s/ Philip W. Coolidge

    Philip W. Coolidge
    President
    March 20, 1998

PORTFOLIO ENVIRONMENT AND OUTLOOK

SHORT-TERM INTEREST RATES GENERALLY DECLINED since CitiFunds Institutional Cash
Reserves commenced operations on October 17, 1997. At the same time, the U.S.
economy continued to grow in the late stages of one of the longest expansions
since World War II. Unlike previous economic cycles, however, this one has been
particularly notable for its persistently low inflation rate. Inflation has
remained benign despite strong economic growth -- about 4% in 1997 -- and low
unemployment.

   A crisis in emerging Asian markets, where currency devaluations in late
October led to sharp drops in stock and bond markets, provided more reason for
investors and economists to conclude that inflation would not become a problem.
Dramatically lower demand from the region for certain goods and services was
expected to dampen U.S. economic growth and relieve inflation pressures.
Accordingly, the Federal Reserve maintained its monetary policy, neither raising
nor lowering key short-term interest rates. The result: most short-term interest
rates and money-market yields declined during the six-month period.

   OUR STRATEGY IS TO ATTEMPT TO CAPTURE HIGH YIELDS in this environment by
allocating the Fund's assets to those sectors of the market that we believe
provide the most attractive relative values. We look for such opportunities in a
variety of areas, including U.S. Treasury bills, commercial paper, certificates
of deposit, repurchase agreements, fixed-time deposits, bankers' acceptances,
asset-backed securities and floating rate notes.

   We found relatively attractive values in high-quality certificates of deposit
for most of the period ended February 28, 1998. Conversely, the fund had little
exposure to U.S. Treasury bills. We held no short-term securities issued by
troubled Asian financial institutions, enabling us to avoid the problems
associated with economic turmoil in the region.

   In addition, we actively manage the average maturity of the Fund in
anticipation of changes in short-term interest rates. When the Fund commenced
operations, the money market curve had already flattened, so we maintained a
neutral average maturity of 40 to 45 days, and we have maintained that position
throughout the reporting period. We have been reluctant to lengthen the Fund's
average maturity because yields on longer-dated money market securities have
declined more rapidly than yields on shorter-dated notes, and we do not believe
that we would be adequately compensated for assuming the incremental risks of a
longer average maturity.

   WE EXPECT YIELDS ON MONEY MARKET SECURITIES TO STAY NEAR OR ONLY SLIGHTLY
BELOW CURRENT LEVELS. If our economic forecast is correct, longer-term interest
rates should decline modestly in response to slower U.S. economic growth. We
believe that the Federal Reserve Board would have little reason to raise
interest rates in a slow-growth environment. In fact, it is possible that the
Federal Reserve might reduce interest rates to stimulate growth if the economy
falters. Therefore, we currently intend to maintain our positions with respect
to the fund's average duration and sector rotation strategies.

   Whatever the next six months hold, we will continue to manage the Fund
according to the approach we have followed for years. We intend to adjust the
average maturity in anticipation of changes in interest rates and shift assets
among the sectors of the short-term market that we believe are most attractive.
We believe this strategy will provide competitive returns commensurate with a
stable principal value.

7-DAY YIELDS
Annualized Current      5.42%
Effective               5.57%

The Annualized Current 7-Day Yield reflects the amount of income generated by
the investment during that seven-day period and assumes that the income is
generated each week over a 365 day period. The yield is shown as a percentage of
the investment.

The Effective 7-Day Yield is calculated similarly, but when annualized the
income earned by the investment during that seven-day period is assumed to be
reinvested. The effective yield is slightly higher than the current yield
because of the compounding effect of this assumed reinvestment.

Note: A money market fund's yield more closely reflects the current earnings of
the fund than does the total return.

COMPARISON OF 7-DAY YIELDS FOR CITIFUNDS INSTITUTIONAL CASH RESERVES VS. IBC

As illustrated, CitiFunds Institutional Cash Reserves generally provided a
higher annualized seven-day yield to that of a comparable IBC Money Fund
Average, as published in IBC Money Fund ReportTM, for the one-year period.

Note: The Fund seeks to maintain a stable $1.00 per share price, although there
is no assurance that this will be so on a continuing basis. Fund shares are not
insured or guaranteed by the U.S. Government. Yields and total returns will
fluctuate and past performance is no guarantee of future results. Total return
figures include reinvestment of dividends. Returns and yields reflect certain
voluntary fee waivers. If the waivers were not in place, the Fund's returns and
yields would have been lower.

CITIFUNDS INSTITUTIONAL CASH RESERVES
NOTES TO FINANCIAL STATEMENTS (Unaudited)

1. SIGNIFICANT ACCOUNTING POLICIES CitiFunds Institutional Cash Reserves (the
"Fund") is a separate non-diversified series of CitiFunds Institutional Trust
(the "Trust"), which is organized as a Massachusetts business trust and is
registered under the Investment Company Act of 1940, as amended, as an open-end,
management investment company. The Investment Manager of the Fund is Citibank,
N.A. ("Citibank"). CFBDS, Inc. ("CFBDS"), (formerly Landmark Funds Broker-Dealer
Services, Inc.) acts as the Fund's Sub-Administrator and Distributor.

   The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.

   The significant accounting policies consistently followed by the Fund are in
conformity with generally accepted accounting principles and are as follows:

   A. VALUATION OF INVESTMENTS Money market instruments are valued at amortized
cost, which the Trustees have determined in good faith constitutes fair value.
This method involves valuing a Fund security at its cost and thereafter assuming
a constant amortization to maturity of any discount or premium. The Fund's use
of amortized cost is subject to the Fund's compliance with certain conditions as
specified under Rule 2a-7 of the Investment Company Act of 1940.

   B. INTEREST INCOME AND EXPENSES Interest income consists of interest accrued
and discount earned (including both original issue and market discount) on the
investments of the Fund, accrued ratably to the date of maturity, plus or minus
net realized gain or loss, if any, on investments. Expenses of the Fund are
accrued daily.

   C. FEDERAL TAXES The Fund's policy is to comply with the provisions of the
Internal Revenue Code available to regulated investment companies and to
distribute to shareholders all of its net investment income. Accordingly, no
provision for federal income or excise tax is necessary.

   D. EXPENSES The Fund bears all costs of its operations other than expenses
specifically assumed by Citibank and CFBDS. Expenses incurred by the Trust with
respect to any two or more Funds in a series are allocated in proportion to the
average net assets of each fund, except when allocations of direct expenses to
each fund can otherwise be made fairly. Expenses directly attributable to a fund
are charged to that fund.

   E. FEES PAID INDIRECTLY The Fund's custodian bank calculates its fees based
on the Fund's average daily net assets. The fee is reduced according to a fee
arrangement, which provides for custody fees to be reduced based on a formula
developed to measure the value of cash deposited with the custodian by the Fund.
This amount is shown as a reduction of expenses on the Statement of Operations.

   F. REPURCHASE AGREEMENTS It is the policy of the Fund to require the
custodian bank to take possession, to have legally segregated in the Federal
Reserve Book Entry System or to have segregated within the custodian bank's
vault, all securities held as collateral in support of repurchase agreement
investments. Additionally, procedures have been established by the Fund to
monitor, on a daily basis, the market value of the repurchase agreement's
underlying investments to ensure the existence of a proper level of collateral.

   G. OTHER Purchases, and maturities and sales of money market instruments are
accounted for on the date of the transaction.

2. DIVIDENDS The net income of the Fund is determined once daily, as of 4:00 pm,
Eastern standard time, and all of the net income of the Fund so determined is
declared as a dividend to shareholders of record at the time of such
determination. Dividends are distributed in the form of additional shares of the
Fund or, at the election of the shareholder, in cash on or prior to the last
business day of the month.

3. MANAGEMENT FEES Citibank is responsible for overall management of the Fund's
business affairs, and has a Management Agreement with the Fund. Citibank also
provides certain administrative services to the Fund. These administrative
services include providing general office facilities and supervising the overall
administration of the Fund. CFBDS acts as Sub-Administrator and performs such
duties and receives such compensation from Citibank as from time to time is
agreed to by Citibank and CFBDS.

   The management fees paid to Citibank, as compensation for overall investment
management services amounted to $127,046, of which $95,728 was voluntarily
waived for the period ended February 28, 1998. The management fees are computed
at an annual rate of 0.20% of the Fund's average daily net assets.

4. DISTRIBUTION FEES The Fund has adopted a Service Plan pursuant to Rule 12b-1
under the Investment Company Act of 1940, as amended, in which the Fund pays
fees for distribution, sales, marketing and shareholder services at an annual
rate not to exceed 0.10% of the Fund's average daily net assets. The
Distribution fee amounted to $42,349 all of which was voluntarily waived for the
period ended February 28, 1998.

5. SHARES OF BENEFICIAL INTEREST The Declaration of Trust permits the Trustees
to issue an unlimited number of full and fractional Shares of Beneficial
Interest (without par value).

6. INVESTMENT TRANSACTIONS Purchases, and maturities and sales of money market
instruments aggregated $4,486,974,203 and $4,050,474,151, respectively, for the
period ended February 28, 1998.

7. FEDERAL INCOME TAX BASIS of Investment Securities The cost of investment
securities owned at February 28, 1998, for federal income tax purposes, amounted
to $436,500,051.

8. LINE OF CREDIT The Fund, along with other CitiFunds, entered into an
agreement with a bank which allows the Funds collectively to borrow up to $60
million for temporary or emergency purposes. Interest on borrowings, if any, is
charged to the specific fund executing the borrowing at the base rate of the
bank. The line of credit requires a quarterly payment of a commitment fee based
on the average daily unused portion of the line of credit. For the period ended
February 28, 1998, the commitment fee allocated to the Fund was $211.
Since the line of credit was established, there have been no borrowings.
