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 Premium 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

                                                                               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 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 PREMIUM LIQUID RESERVES VS. IBC

As illustrated, CitiFunds Premium 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 Report(TM), for the one
year period.

CITIFUNDS PREMIUM LIQUID RESERVES
NOTES TO FINANCIAL STATEMENTS (Unaudited)


1.  SIGNIFICANT  ACCOUNTING  POLICIES  CitiFunds  Premium  Liquid  Reserves (the
"Fund")  is a  separate  diversified  series of  CitiFunds  Premium  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  (6.2% 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 cusotmers 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 when 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 0.40%,  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 $1,509,556 of
which  $725,461 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 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.  Shareholder
Servicing  Agent fees amounted to $431,302 for the six months ended February 29,
2000.

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  Premium 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

                                                                               1
<PAGE>

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.

<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.


FUND FACTS

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 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.

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 PREMIUM U.S. TREASURY RESERVES
NOTES TO FINANCIAL STATEMENTS (Unaudited)

1. SIGNIFICANT ACCOUNTING POLICIES CitiFunds Premium U.S. Treasury Reserves (the
"Fund")  is a  diversified  separate  series of  CitiFunds  Premium  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 (26.5% 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  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  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 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 0.45%.

   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 $468,548,
of which $222,095 was  voluntarily  waived for the six months ended February 29,
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, 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 $133,871 for the six months ended February 29,
2000.

4. DISTRIBUTION FEES  The Trust 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
$133,871,  all of which was voluntarily waived for the six months ended February
29, 2000. The  Distributor  has  voluntarily  agreed to assume all  distribution
expenses through 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
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 $899,841 of
which  $520,464 was  voluntarily  waived for the six months  ended  February 29,
2000. The investment  advisory fee is computed at an annual rate of 0.15% of the
Portfolio's average daily net assets.




                                                                              15

U.S. TREASURY RESERVES PORTFOLIO
NOTES TO FINANCIAL STATEMENTS (Unaudited) (Continued)

   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.
