LETTER TO OUR SHAREHOLDERS


Dear Shareholder:

   Rising interest rates during the reporting period have benefited money market
investors,  who earned  higher  yields  while  preserving  capital.  The Federal
Reserve  Board (the "Fed")  raised  interest  rates three times in 1999 and most
recently on February 2, 2000, for a total increase of 100 basis points. (A basis
point  is .01% or one  one-hundredth  of a  percent.)  The  Fed's  actions  were
implemented to forestall a reacceleration of inflation,  a potential consequence
of the continued robust growth of the U.S. economy.

   In this  environment,  the CitiFunds'  investment  adviser,  Citibank,  N.A.,
continued to manage  CitiFunds  Institutional  Liquid  Reserves with the goal of
achieving its investment  objective:  providing liquidity and as high a level of
current income as is consistent with the preservation of capital.

   This report reviews the Fund's investment  activities and performance  during
the six months ended  February 29,  2000,  and provides a summary of  Citibank's
perspective on and outlook for the money market securities marketplace.

   Thank you for your continued confidence and participation.

Sincerely,

/s/ Philip W. Coolidge

PORTFOLIO ENVIRONMENT AND OUTLOOK

   THE PAST SIX MONTHS HAVE BEEN GENERALLY REWARDING FOR MANY MONEY MARKET
INVESTORS. Yields on most money market securities ended the six-month reporting
period higher than where they began, reflecting the general trend of higher
short-term interest rates in a period of rising interest rates.

   The economic conditions that led to higher rates during the reporting period
included strong U.S. economic growth, low inflation, robust consumer spending
and rising demand for U.S. exports. Even concerns regarding potential
Y2K-related problems did not cause the rate of economic growth to moderate
significantly.

   As a result of these influences, many investors became concerned that
unsustainable economic growth might cause long-dormant inflationary pressures to
resurface. In an attempt to forestall a potential reacceleration of inflation,
the Fed raised interest rates three 25-basis point increments during 1999 and
raised rates an additional 25 basis points on February 2, 2000.

   THE FUND'S MANAGERS' PRIMARY STRATEGY DURING MOST OF THE SIX-MONTH PERIOD WAS
TO ACTIVELY MANAGE THE FUND'S AVERAGE MATURITY according to their outlook
regarding the direction of interest rates and prevailing yields among money
market instruments of different maturities. (Maturity is the date on which the
principal amount of a note, draft, acceptance bond or other debt instrument
becomes due and payable.) When the six-month reporting period began, the
managers maintained the Fund's neutral average maturity, striking a balance
between the need for flexibility during a period of rising interest rates while
purchasing securities they believed to be of compelling values. Toward the end
of 1999, the Fund's average maturity was reduced in order to enhance liquidity
and keep assets available for higher-yielding securities as they became
available.

   Beginning in the middle of January 2000, the Fund's managers began to
gradually extend the Fund's average maturity to take advantage of
higher-yielding opportunities among money market instruments with moderately
longer maturities. As of February 29, 2000, the Fund's average maturity was 85
days.

   ADDITIONALLY, THE MANAGERS ACTIVELY MANAGED THE MIX OF MONEY MARKET
INSTRUMENTS WITHIN THE PORTFOLIO. As interest rates rose, commercial paper and
bank certificates of deposit represented the most attractive values, in the
managers' opinion. For example, toward year-end 1999, the managers shifted
assets to high quality, U.S. dollar-denominated CDs issued by foreign banks
(known as Yankee CDs) in order to capture higher yields. On the other hand, the
managers generally avoided U.S. Treasury bills, which offered relatively low
yields throughout the six-month period.

   Looking forward, the Fund's managers believe that investors are expecting
more rate hikes from the Fed, and that future INCREASES HAVE ALREADY BEEN
INCORPORATED IN THE YIELDS OF MONEY MARKET SECURITIES. ACCORDINGLY, THE FUND'S
MANAGERS BELIEVE THAT OVER THE LONGER TERM, INTEREST RATES MAY BEGIN TO DECLINE
IF THE U.S. ECONOMY BEGINS TO SHOW EVIDENCE THAT IT IS MODERATING. Therefore,
the managers are carefully looking for opportunities to take advantage of
changes in interest rates, including possibly extending the Fund's average
maturity further to lock in higher yields when deemed appropriate.

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 FINANCIAL DATA 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 Financial Data
Money Market Funds Average, as published in IBC Money Fund ReportTM, for the one
year period.

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.  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.  The value of such investment
reflects the Fund's  proportionate  interest (40.5% at February 29, 2000) in the
net  assets  of the  Portfolio.  CFBDS,  Inc.  ("CFBDS")  acts  as  the  Trust's
Administrator  and Distributor.  Citibank also serves as  Sub-Administrator  and
makes shares available to customers as Shareholder Servicing Agent.

   The  preparation of financial  statements in accordance  with U.S.  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 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 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.

                                                                               9

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. For the six months ended February 29, 2000,
management  agreed to  voluntarily  limit Fund  expenses to 0.20,  inclusive  of
Portfolio allocated expenses.

   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  $10,338,032 of
which  $8,311,432 was  voluntarily  waived for the six months ended February 29,
2000.  Citibank  acts as  Sub-Administrator  and  performs  certain  duties  and
receives  compensation  from  CFBDS  from time to time as agreed to by CFBDS and
Citibank. Citibank is a wholly-owned subsidiary of Citigroup Inc.

   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  $2,953,723,  all of which was  voluntarily
waived for the six months ended February 29, 2000.

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 $2,953,723,  all of which was voluntarily  waived for the six months
ended  February  29,  2000.  The  Distributor  voluntarily  agreed to assume all
distribution expenses through February 29, 2000.

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 $13,368,300,164 and $13,709,027,988,  respectively, for
the six months ended February 29, 2000.

                                                                              11

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.
Citibank is a wholly-owned subsidiary of Citigroup Inc.

   The  preparation of financial  statements in accordance with United States of
America 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 AGREEMENT  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.  OTHER  Purchases, maturities and  sales of money market  instruments  are
accounted for on the date of the transaction.

                                                                              19

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 $11,526,046
of which $5,707,922 was voluntarily waived for the six months ended February 29,
2000.  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 $3,842,015, all of which were voluntarily waived
for the six months ended February 29, 2000.  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 $175,256,041,856 and $175,492,697,226,  respectively, for
the six months ended February 29, 2000.

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 $75
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 29, 2000,  the  commitment  fee  allocated to the  Portfolio was
$22,033.  Since  the  line  of  credit  was  established,  there  have  been  no
borrowings.

LETTER TO OUR SHAREHOLDERS


Dear Shareholder:

   Rising interest rates during the reporting period have benefited money market
investors,  who earned  higher  yields  while  preserving  capital.  The Federal
Reserve  Board (the "Fed")  raised  interest  rates three times in 1999 and most
recently on February 2, 2000 for a total increase of 100 basis points.  (A basis
point  is .01% or one  one-hundredth  of a  percent.)  The  Fed's  actions  were
implemented to forestall a reacceleration of inflation,  a potential consequence
of the continued growth of the U.S. economy.

   In this  environment,  the CitiFunds'  investment  adviser,  Citibank,  N.A.,
continued to manage CitiFunds Institutional U.S. Treasury Reserves with the goal
of achieving its investment  objective:  providing liquidity and as high a level
of current income from U.S.  government  obligations  as is consistent  with the
preservation of capital.

   This report reviews the Fund's investment  activities and performance  during
the six months ended  February 29,  2000,  and provides a summary of  Citibank's
perspective on and outlook for the money market securities marketplace.

   Thank you for your continued confidence and participation.

Sincerely,



/s/ Philip W. Coolidge

Philip W. Coolidge

March 15, 2000


                                                                               1

PORTFOLIO ENVIRONMENT AND OUTLOOK

   THE PAST SIX MONTHS  HAVE BEEN  GENERALLY  REWARDING  FOR MANY  INVESTORS  IN
SHORT-TERM  U.S.  TREASURY  SECURITIES.  Yields  on such  investments  ended the
six-month reporting period higher than where they began,  reflecting the general
trend of higher short-term  interest rates in a period of rising interest rates.
While rising interest rates  negatively  affected the prices of long-term bonds,
price declines were much more modest among  short-term  securities such as those
in which the Portfolio invests.

   The positive economic conditions that led to higher interest rates during the
reporting  period included strong U.S.  economic growth,  low inflation,  robust
consumer  spending  and  rising  demand for U.S.  exports.  As a result of these
factors, many investors became concerned that unsustainable U.S. economic growth
might cause  inflationary  pressures to resurface.  As previously  noted,  in an
attempt to forestall a potential  reacceleration  of  inflation,  the Fed raised
interest rates in three 25-basis point increments during 1999 and raised them an
additional 25 basis points on February 2, 2000.

   DESPITE THE POSITIVE  EFFECTS OF HIGHER  INTEREST  RATES,  THE U.S.  TREASURY
MARKET'S RETURNS WERE CONSTRAINED BY ITS OWN  MARKET-SPECIFIC  INFLUENCES,  MOST
NOTABLY CHANGES IN THE BALANCE BETWEEN SUPPLY AND DEMAND. Issuance of short-term
U.S.  Treasury  securities  generally fell during the reporting  period,  as the
strong U.S.  economy  enabled the federal  government to post a budget  surplus,
reducing the government's need to borrow.

   At the same time,  demand was strong  from  foreign  and  domestic  investors
seeking a relatively  safe place for money awaiting  reinvestment in longer-term
securities.  Because of this imbalance between supply and demand, yields on U.S.
Treasury  securities  tended  to rise  less  than  yields  of  other  short-term
instruments.

   THE PORTFOLIO  MANAGERS' STRATEGY DURING THE SIX-MONTH PERIOD WAS TO MAINTAIN
A RELATIVELY SHORT AVERAGE MATURITY, which was designed to enhance liquidity and
keep assets available for  higher-yielding  securities as they became available.
As of February 29, 2000, the Portfolio's average maturity was 52 days. (Maturity
is the date on which the principal amount of a note,  draft,  acceptance bond or
other debt  instrument  becomes due and payable.) The  portfolio's  policy is to
maintain  a  maximum  average  maturity  of not  more  than 60 days in  order to
maintain  its AAA/Aaa  ratings by both  Standard & Poor's and Moody's  Investors
Service Inc.  (Standard & Poor's  Corporation and Moody's  Investor Service Inc.
are two major credit reporting and bond-rating agencies.)

   In addition,  THE MANAGERS  ACTIVELY MANAGED THE MIX OF MATURITIES WITHIN THE
FUND'S PORTFOLIO.  Because of year-end and Y2K-related concerns,  many investors
gravitated  to U.S.  Treasury  securities  maturing  during the first quarter of
2000. The Fund's managers avoided these maturities  because of their low yields.
Instead,  short-term  securities were emphasized as the end of 1999  approached,
and the investment team purchased short-term Cash Management Bills issued by the
U.S.  Treasury to ensure market  liquidity  during the  transition  from 1999 to
2000.  Y2K-related  market  disruptions  have  not  materialized.  However,  the
managers took  advantage of this  temporary  opportunity to capture higher yield
potential for the Fund's portfolio.


2
<PAGE>

   Looking forward,  the Fund's managers expect interest rates to remain near or
slightly  above  current  levels  if the Fed  continues  to move  toward  a more
restrictive  monetary policy.  However,  MANAGEMENT  BELIEVES THAT OVER THE LONG
TERM, INTEREST RATES MAY BEGIN TO DECLINE IF THE ECONOMY BEGINS TO SHOW EVIDENCE
THAT IT IS  MODERATING.  Accordingly,  the managers are carefully  searching for
opportunities  to take advantage of changes in the direction of interest  rates,
including possibly extending the Fund's average maturity within its conservative
parameters to lock in higher yields in the near term.

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:  Mutual fund shares are not  guaranteed or insured by the Federal  Deposit
Insurance  Corporation or any other government agency.  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.

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. 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"),  an open-end,  diversified
management  investment company for which Citibank,  N.A.  ("Citibank") serves as
Investment   Adviser.   The  value  of  such  investment   reflects  the  Fund's
proportionate  interest  (49.2% at February  29,  2000) in the net assets of the
Portfolio.  CFBDS,  Inc.  ("CFBDS"),  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. Citibank is
a wholly-owned subsidiary of Citigroup Inc.

   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.


                                                                               9

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. For the six months ended February 29, 2000,
management agreed to voluntarily limit Fund expenses to 0.25%.

   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 $1,042,733,
of which $669,326 was contractually waived for the six months ended February 29,
2000.  The  contractual  fee waivers of 0.20%  terminate  on December  31, 2000.
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  AGENT 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  $297,924,  all of which were  contractually
waived for the six months ended February 29, 2000. The  contractual  fee waivers
terminate on December 31, 2000.

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 $297,924,  all of which was contractually  waived for the six months
ended February 29, 2000. The contractual  fee waivers  terminate on December 31,
2000.  The  Distributor  has  contractually  agreed to assume  all  distribution
expenses through February 29, 2000.

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  $1,090,238,899 and $1,109,181,763,  respectively,  for
the six months ended February 29, 2000.

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.
CFBDS,  Inc  ("CFBDS"),  acts as the  Portfolio's  Administrator.  Citibank N.A.
("Citibank")  acts  as  the  Investment  Adviser.  Citibank  is  a  wholly-owned
subsidiary of Citigroup Inc.

   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  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

   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  $299,947,  all of which was
contractually waived for the six months ended February 29, 2000. The contractual
fee waivers  terminate on December 31, 2000. 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 $5,191,970,429 and $5,156,117,240, respectively, for the
six months ended February 29, 2000.

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 $75
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 29, 2000,  the  commitment  fee  allocated to the  Portfolio was
$1,815. Since the line of credit was established, there have been no borrowings.

LETTER TO OUR SHAREHOLDERS

Dear Shareholder:

   Rising interest rates during the reporting  period have benefited  tax-exempt
money market investors,  who earned higher yields while preserving capital.  The
Federal  Reserve Board (the "Fed") raised interest rates three times in 1999 and
most recently on February 2, 2000 for a total  increase of 100 basis points.  (A
basis point is .01% or one  one-hundredth  of a percent.) The Fed's actions were
implemented to forestall a reacceleration of inflation,  a potential consequence
of the continued robust growth of the U.S. economy.

   In this  environment,  the CitiFunds'  investment  adviser,  Citibank,  N.A.,
continued to manage CitiFunds  Institutional  Tax Free Reserves with the goal of
achieving its investment objective: providing high levels of current income that
are exempt from federal income taxes, preservation of capital and liquidity.

   This report reviews the Fund's investment  activities and performance  during
the six months ended  February 29,  2000,  and provides a summary of  Citibank's
perspective  on  and  outlook  for  the  tax-exempt   money  market   securities
marketplace.

   Thank you for your continued confidence and participation.

Sincerely,

/s/ Philip W. Coolidge
    ------------------

PORTFOLIO ENVIRONMENT AND OUTLOOK

   THE PAST SIX MONTHS  HAVE BEEN  GENERALLY  REWARDING  FOR MANY  MONEY  MARKET
INVESTORS.  Yields on  tax-exempt  money market  securities  ended the six-month
reporting  period higher than where they began,  reflecting the general trend of
short-term interest rates in a period of rising interest rates.

   The economic  conditions that led to higher rates during the reporting period
included strong U.S.  economic growth,  low inflation,  robust consumer spending
and rising demand for U.S. exports. As a result of these factors, many investors
became  concerned that  unsustainable  economic growth might cause  inflationary
pressures to resurface. In an attempt to forestall a potential reacceleration of
inflation,  the Fed raised  interest rates in three  25-basis  point  increments
during 1999 and raised them an additional 25 basis points on February 2, 2000.

   DESPITE  THE  POSITIVE  EFFECTS  OF  HIGHER  INTEREST  RATES,   HOWEVER,  THE
TAX-EXEMPT  MONEY MARKET'S  RETURNS WERE  CONSTRAINED BY ADVERSE  CHANGES IN THE
BALANCE BETWEEN SUPPLY AND DEMAND.  Issuance of short-term  municipal securities
generally  fell during the  reporting  period  because  the strong U.S.  economy
enabled  many states and  municipalities  to improve  their  fiscal  operations,
reducing their need to borrow in order to cover short-term deficits. At the same
time,  demand  rose from  individuals  seeking  competitive  tax-exempt  yields.
Because of this  imbalance  between supply and demand,  tax-exempt  money market
yields tended to rise less than the yields of taxable money market instruments.

   THE FUND'S  MANAGERS'  STRATEGY DURING THE SIX-MONTH PERIOD WAS TO MAINTAIN A
RELATIVELY SHORT AVERAGE  MATURITY,  which was designed to enhance liquidity and
keep assets available for higher yielding  securities as they became  available.
As of February 29, 2000, the Fund's average  maturity was 33 days.  (Maturity is
the date on which the  principal  amount of a note,  draft,  acceptance  bond or
other debt instrument becomes due and payable.)

   IN  ADDITION,   THE  MANAGERS  ACTIVELY  MANAGED  THE  MIX  OF  MONEY  MARKET
INSTRUMENTS  WITHIN THE FUND'S PORTFOLIO DURING THE REPORTING PERIOD. A relative
shortage  of  municipal  notes  made it  more  difficult  to find  high-yielding
opportunities in high-quality, highly liquid instruments. Instead, opportunities
were  located  primarily  in  Variable  Rate  Demand  Notes  (VRDNs),  which are
short-term instruments that are securitized and issued by investment banks..

   At the end of 1999,  daily and weekly VRDNs comprised about 69% of the Fund's
portfolio.  This highly  liquid  asset mix was designed to protect the Fund from
potential  Y2K-related  problems  that  have  not  surfaced.  By the  end of the
reporting  period,  VRDNs comprised  approximately  67% of the Fund's portfolio,
with the remainder  allocated among  municipal  notes and tax-exempt  commercial
paper.

   Looking forward,  the Fund's managers expect interest rates to remain near or
slightly  above  current  levels  if the Fed  continues  to move  toward  a more
restrictive monetary policy.  However, THE MANAGERS BELIEVE THAT OVER THE LONGER
TERM, INTEREST RATES MAY BEGIN TO DECLINE IF THE ECONOMY BEGINS TO SHOW EVIDENCE
THAT IT IS  MODERATING.  Accordingly,  the  managers are  carefully  looking for
opportunities to take advantage of changes in interest rates, including possibly
extending the Fund's average maturity to lock in higher yields in the near term.

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.

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.  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.  The value of such
investment reflects the Fund's  proportionate  interest  (approximately 19.9% at
February 29, 2000) in the net assets of the Portfolio.  CFBDS,  Inc.  ("CFBDS"),
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. Citibank is a wholly-owned subsidiary of Citigroup Inc.

   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.  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.

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

                                                                               9

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. For the six months ended February 29, 2000, management
agreed to voluntarily limit Fund expenses to 0.25%.

   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 $212,524,  of which $205,146 was  contractually
waived for the six months ended February 29, 2000. The contractual fee waiver of
0.25% terminates on December 31, 2000.  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 $60,721 all of which was  contractually  waived
for the  six  months  ended  February  29,  2000.  The  contractual  fee  waiver
terminates  on December 31, 2000.

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 $60,721,  all of which was  contractually  waived for the six months
ended February 29, 2000. The contractual  fee waiver  terminates on December 31,
2000.

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,  nondiversified,  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"),  acts as the Portfolio's  Administrator.  Citibank,  N.A.
("Citibank")  acts  as  the  Investment  Adviser.  Citibank  is  a  wholly-owned
subsidiary of Citigroup Inc.

   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 Portfolio's custodian 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 FEE AND ADMINISTRATIVE FEE

   A.  INVESTMENT ADVISORY FEE  The investment advisory fee paid to Citibank, as
compensation for overall investment  management services,  amounted to $615,240,
of which $262,136 was  voluntarily  waived for the six months ended February 29,
2000. 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  $153,810,  all of which was  voluntarily  waived for the six months
ended February 29, 2000. The Port-

folio  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 $1,251,850,907 and $1,245,096,446,  respectively,  for the six months
ended February 29, 2000.

4. FEDERAL INCOME TAX BASIS OF INVESTMENT SECURITIES   The  cost  of  investment
securities owned at February 29, 2000, for federal income tax purposes, amounted
to $671,113,025.

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 $75
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 29, 2000, the commitment fee allocated to the Portfolio was $814.
Since the line of credit was established, there have been no borrowings.

                                                                              23

LETTER TO OUR SHAREHOLDERS


Dear Shareholder:

   Rising interest rates during the reporting period have benefited money market
investors,  who earned  higher  yields  while  preserving  capital.  The Federal
Reserve  Board (the "Fed")  raised  interest  rates three times in 1999 and most
recently on February 2, 2000 for a total increase of 100 basis points.  (A basis
point  is .01% or one  one-hundredth  of a  percent.)  The  Fed's  actions  were
implemented to forestall a reacceleration of inflation,  a potential consequence
of the continued robust growth of the U.S. economy.

   In this  environment,  the CitiFunds'  investment  adviser,  Citibank,  N.A.,
continued  to manage  CitiFunds  Institutional  Cash  Reserves  with the goal of
achieving its investment  objective:  providing liquidity and as high a level of
current income as is consistent with the preservation of capital.

   This report reviews the Fund's investment  activities and performance  during
the six months ended  February 29,  2000,  and provides a summary of  Citibank's
perspective on and outlook for the money market securities marketplace.

   Thank you for your continued confidence and participation.

Sincerely,


/s/ Philip W. Coolidge

                                                                               1
<PAGE>

PORTFOLIO ENVIRONMENT AND OUTLOOK
   THE PAST SIX MONTHS  HAVE BEEN  GENERALLY  REWARDING  FOR MANY  MONEY  MARKET
INVESTORS.  Yields on most money market securities ended the six-month reporting
period higher than where they began,  reflecting the general trend of short-term
interest rates in a period of rising interest rates.
   The  economic  conditions  that  led to  higher  interest  rates  during  the
reporting  period included strong U.S.  economic growth,  low inflation,  robust
consumer  spending  and  rising  demand for U.S.  exports.  As a result of these
factors,  many investors  became  concerned that  unsustainable  economic growth
might cause  inflationary  pressures to resurface.  As previously  noted,  in an
attempt to forestall a potential  reacceleration  of  inflation,  the Fed raised
interest rates in three 25-basis point increments during 1999 and raised them an
additional 25 basis points on February 2, 2000.
   THE FUND'S  MANAGERS'  STRATEGY DURING THE SIX-MONTH PERIOD WAS TO MANAGE THE
FUND'S  AVERAGE  MATURITY  OPPORTUNISTICALLY,  extending and reducing the Fund's
sensitivity to changing  interest  rates.  For example,  immediately  before the
Federal Reserve Board's Open Market Committee meetings in November and February,
the managers extended the Fund's average maturity to take advantage of a steeper
yield  curve.  (The yield curve is the  graphic  depiction  of the  relationship
between the yield on bonds of the same credit quality but different maturities.)
The managers also extended maturities just prior to the date change from 1999 to
2000, when higher yielding securities were temporarily available. As of February
29, 2000, the Fund's average maturity was 17 days.
   In  addition,   THE  MANAGERS  ACTIVELY  MANAGED  THE  MIX  OF  MONEY  MARKET
INSTRUMENTS WITHIN THE FUND'S PORTFOLIO.  In the managers' opinion,  as interest
rates  rose,  asset-backed  commercial  paper and bank  certificates  of deposit
represented the most attractive values. For example, toward the end of 1999, the
Fund's assets were shifted to high quality, U.S.  dollar-denominated  CDs issued
by foreign banks (known as Yankee CDs) in order to capture  higher  yields.  The
Fund's managers also found occasional  opportunities in U.S.  government  agency
securities selling at a discount to face value. On the other hand, U.S. Treasury
bills, which offered relatively low yields throughout the six-month period, were
avoided.
   Looking forward,  the Fund's managers expect interest rates to remain near or
slightly  above  current  levels  if the Fed  continues  to move  toward  a more
restrictive  monetary policy.  However,  THE MANAGERS BELIEVE THAT OVER THE LONG
TERM, INTEREST RATES MAY BEGIN TO DECLINE IF THE ECONOMY BEGINS TO SHOW EVIDENCE
THAT IT IS  MODERATING.  Accordingly,  the managers are watching  carefully  for
opportunities to take advantage of changes in interest rates, including possibly
extending  the Fund's  average  maturity to lock in higher  yields over the near
term.

7-DAY YIELDS
Annualized Current5.65%
Effective         5.81%

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  Cash Reserves  generally  provided a
higher  annualized  seven-day  yield to that of a comparable  IBC Financial Data
Money Market Funds Average,  as published in IBC Money Fund Report(TM),  for the
one-year period.

Note:  Mutual fund shares are not  guaranteed or insured by the Federal  Deposit
Insurance  Corporation or any other government agency.  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"),  acts as the Fund's Sub-Administrator
and Distributor. Citibank is a wholly-owned subsidiary of Citigroup Inc.
   The Fund offers  Class L and Class S shares.  The Fund  commenced  its public
offering  of Class S shares  on  October  6,  1999.  Each  class  has  different
eligibility  requirements and its own combination of charges and fees.  Expenses
of the Fund are borne  pro-rata by the  holders of each class of shares,  except
that each class bears  expenses  unique to that class  (including the Rule 12b-1
service and  distribution  fees applicable to such class),  and votes as a class
only with respect to its own Rule 12b-1 plan. Shares of each class would receive
their pro-rata share of the assets of the Fund, if the Fund were liquidated.
   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.  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

10

CITIFUNDS INSTITUTIONAL CASH RESERVES
NOTES TO FINANCIAL STATEMENTS (Unaudited)

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.
   F. 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 5:00 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 $354,144,  of which  $203,259 was  voluntarily
waived for the six months  ended  February  29, 2000.  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 per Class L and Class S
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% and 0.25% of the Fund's  Class L
and Class S average daily net assets respectively. The Distribution fee amounted
to $175,247 of which $88,399 was voluntarily  waived for Class L, and $4,590 for
Class S for the six months ended February 29, 2000.

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 $6,797,723,701 and $6,670,732,657,  respectively, for the
six months ended February 29, 2000.

7. FEDERAL  INCOME TAX BASIS OF  INVESTMENT  SECURITIES  The cost of  investment
securities owned at February 29, 2000, for federal income tax purposes, amounted
to $531,686,973.


                                                                              11

CITIFUNDS INSTITUTIONAL CASH RESERVES

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 $75
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 29, 2000,  the  commitment  fee  allocated to the Fund was $437.
Since the line of credit was established, there have been no borrowings.
