Dear Shareholders: 

    We are pleased to present  the  Semi-Annual  Report for the Lehman  Brothers
Institutional  Funds Group Trust (the "Trust" or the "Funds") for the  six-month
period ended July 31, 1996. This Report includes the portfolio  holdings for the
Prime,  Government and Tax-Exempt  Money Market Funds  currently  offered by the
Trust that are  designed  to meet the cash  management  and  liquidity  needs of
institutional investors.

THE ECONOMY 

    The underlying strength of the U.S. economy in the first quarter of 1996 was
extremely difficult to gauge. Early in the period, economic activity appeared to
be on the verge of recession  following a very anemic fourth  quarter of 1995 in
which Gross Domestic Product ("GDP") growth was only 0.5%.  Short-term  interest
rates trended lower as most  investors  believed that the Federal  Reserve Board
(the "Fed")  would ease  monetary  policy by reducing the target fed funds rate,
which  it  did  on  January  31,  1996  by 25  basis  points,  citing  "receding
inflationary  pressures and a moderating economic  expansion."  Long-term rates,
however,   had  begun  to  rise  in   December  as  bond   investors   expressed
disappointment over congressional  failure to reach agreement on balanced budget
legislation.  As February began, the economic landscape became less clear due to
the lack of timeliness and reliability of economic data that was released in the
aftermath of the shutdown of U.S. Government operations.  Faced with uncertainty
as to the strength,  or even  direction,  of the economy,  anxious  fixed-income
investors  engaged in a  sell-off  in late  February  after  Chairman  Greenspan
testified at the  Humphrey-Hawkins  hearings that the economy was healthier than
the data would indicate.

    As March began, the most  significant  event was the release of the February
Employment  Report  which  showed a huge  increase in job  creation.  Short- and
long-term  interest rates gapped upward as investors  acknowledged a major shift
in  economic  expectations  from one of modest  growth  with low  inflation  and
declining interest rates to one which was based upon faster growth, concern over
inflation, and the possibility of a pre-emptive tightening of monetary policy by
the Fed. In April, investors were looking for the economic data flow to begin to
exhibit a clear trend that was not distorted by the government shutdown,  severe
weather,  or the General Motors strike.  As the quarter  unfolded,  a pattern of
strength became apparent in many sectors of the economy.  Consumer sentiment was
buoyed  by  strong  job  growth,  higher  income,  and the  wealth  effect  of a
spectacular stock market. This elevated consumer willingness to spend on housing
and other consumer  durables such as autos.  Increased  consumer debt also was a
factor in spurring retail sales. On the production side,  inventory levels were,
for the most part,  at desired  levels  which gave  manufacturers  the chance to
crank up  production in order to meet the new demand.  All the while,  inflation
remained  manageable,  although  slight  pressure  became  noticeable in certain
commodities and employees' wages.

    As a result of this indisputable strength, economists were obliged to revise
their estimates for GDP for the first and second quarters and the full year. The
actual first quarter GDP of 2.2% was well above early  estimates of 1.5% and the
second quarter  preliminary  rate of growth was 4.2%.  This pace, in combination
with an outlook for slower  growth in the second half of 1996,  would  translate
into an annual  rate of about 2.5% to 3.0% which we  believe  exceeds  the Fed's
target for sustainable growth without inflation.  Throughout the second quarter,
fixed-income  investors  became  convinced  that the Fed would soon adopt a more
restrictive  monetary  policy  in light of the  economic  strength  even  though
inflation  was still  below 3.0% -- the only  question  was one of timing.  As a
result of this consensus,  long-term Treasury rates rose from 6.69% on March 29,
1996 to as high as 7.20% in mid-June. A strong rally in early August brought the
rate back down to 6.68%  based  upon  weaker  July data.  The rate  subsequently
retraced to 7.00% by late August as the market resumed its Fed tightening  vigil
after new signs of strength.  The  three-month  Treasury  bill rate movement was
much more modest, rising from 5.14% to a high of 5.30% before settling back down
to 5.20%.

PORTFOLIO STRATEGY AND PERFORMANCE RESULTS 

  TAXABLE FUNDS 

    Early in the period,  the average  maturities  of the Taxable  Money  Market
Funds were  extended  modestly in line with the Fed's  policy of monetary  ease.
However,  as the economy  strengthened  and the probability for a tighter policy
loomed,  the strategy was changed to shorten  portfolios  as much as possible in
order to provide for expected  greater  liquidity needs and to take advantage of
expected higher rates.  In spite of the fact that the short-term  yield curve is
relatively  steep from one day to one year (75 basis points) in  anticipation of
some Fed tightening action, it is too early to undertake a meaningful  extension
without more  conclusive  economic  data. The targeted  average  maturity of the
taxable funds remains at 30-45 days.


                                       1


  TAX-EXEMPT FUNDS 

    Unlike the taxable  fixed-income  market  which was driven by  economic  and
monetary  signals,  the tax-  exempt  market was  influenced  more by  technical
factors over the course of the period and  experienced a high degree of seasonal
volatility.  Rates began the second  quarter at seasonally  low levels due to an
infusion of cash in early April from bond coupon payments and normal maturities.
Mid-April saw a reversal as individuals  made  redemptions from tax-exempt funds
in order to make personal income tax payments. This forced fund managers to sell
some securities which pushed rates higher.  This trend was reversed in early May
as cash from May coupon payments and maturities flowed into the market and drove
rates lower once again.  By mid-May,  the cash had been fully invested and rates
rose as demand eased. The June experience was similar to that of May.

    We expected to see a gradual upward  movement of rates in July and August as
the  previously-described  note proceeds were absorbed by a growing  calendar of
re-issued notes.  These two factors created the first buying  opportunity of the
third  quarter  and  we  attempted  to  take  advantage  by  extending   average
maturities.

    The Trust  continued to perform well when  compared  with other money market
funds offered to the institutional  investor. For example, based on total return
for the 12 months ended July 31, 1996, Prime Value Money Market Fund Class A was
ranked  third and Prime Money  Market Fund Class A ranked fifth place out of the
139 First Tier  Institutional  Only Funds tracked by IBC/Donaghue,  Inc.'s Money
Fund Insight  ("IBC/  Donoghue").  The  Municipal  Money Market Fund Class A and
Tax-Free Money market Fund Class A were the number one- and  four-ranked  funds,
respectively,  among 71 tax-free  institutional funds reporting to IBC/Donoghue.
Some or all of the funds in each category,  including the Lehman Brothers Funds,
reported expense  reimbursements  or fee waivers from time to time without which
the reported returns would have been lower.  Past performance is no guarantee of
future results.

                                * * * * * 

    As you have most likely been made aware at this time,  the Board of Trustees
of Lehman Brothers Institutional Funds Group Trust (the "Trust") has unanimously
endorsed a proposal (a) to combine three of its funds with three portfolios of a
trust sponsored by Federated  Investors and (b) to change the investment advisor
of three other funds from Lehman Brothers  Global Asset  Management to Federated
Management. Each transaction requires shareholder approval and will also involve
the election of new Trustees of the Trust.

    With respect to Prime Money Market Fund,  Prime Value Money Market Fund, and
Municipal Money Market Fund, shareholders will be asked to approve adoption of a
new  investment  advisory  contract  with  Federated  Management,  an investment
advisory subsidiary of Federated Investors, and the election of the new Trustees
to the Trust.

    With  respect  to  Government   Obligations  Money  Market  Fund,   Treasury
Instruments Money Market Fund II, and Tax-Free Money Market Fund  (individually,
the  "Fund"),  shareholders  of each  Fund,  will be asked to approve a proposed
Agreement and Plan of Reorganization  between the Trust, on behalf of each Fund,
and Money Market  Obligations  Trust,  on behalf of one of its  portfolios  (the
"Portfolio"),  whereby a  Portfolio  of Money  Market  Obligations  Trust  would
acquire all of the assets of the  relevant  Fund in exchange  for  Institutional
Shares and  Institutional  Service Shares of the Portfolio to be distributed pro
rata by the Fund to holders of Class A Shares and Class B Shares,  respectively,
in complete liquidation of the Fund.

    Federated  Investors,  founded  in 1955,  is a  Pittsburgh-based  investment
manager with approximately $70 billion in assets under management. Federated has
been a pioneer in cash management,  having created the first institutional money
market  fund in 1976.  Federated  currently  offers over 40 money  market  funds
managed specifically to meet the requirements of the institutional market.

Sincerely,

the public:  Prime Money Market Fund, Prime Value Money Market Fund,  Government
Obligations Money Market Fund, Cash Management Fund, Treasury  Instruments Money
Market Fund II,  Tax-Free  Money  Market Fund and  Municipal  Money  Market Fund
(collectively,  the  "Funds").  All the  Funds,  except  Cash  Management  Fund,
currently  offer four classes of shares:  Class A, Class B, Class C and Class E.
Cash  Management Fund currently  offers Class A Shares only.  Class A shares are
sold to institutional investors that have not entered into servicing agreements.
Class B, Class C and Class E shares are sold to institutional investors and bear
service fees. All classes of shares have identical rights and privileges  except
that Class B, Class C and Class E possess  certain  exclusive  voting  rights on
matters relating to their respective service fees.

     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 following is a
summary of significant accounting policies consistently followed by the Funds in
the preparation of their financial statements.

     Portfolio valuation:  Securities of the Funds are valued at amortized cost,
which  approximates  market value.  Amortized cost valuation  involves valuing a
security at cost initially, and, thereafter, assuming a constant amortization to
maturity  of any  discount  or  premium,  as long as the  effect of  fluctuating
interest rates on the market value of the instruments is not significant.

     Repurchase  agreements:  Certain Funds may engage in  repurchase  agreement
transactions. The Fund values repurchase agreements at cost and accrues interest
into interest receivable.  Under the terms of a typical repurchase agreement,  a
Fund takes possession of the underlying debt obligation subject to an obligation
of the  seller to  repurchase,  and the Fund to  resell,  the  obligation  at an
agreed-upon  price and time,  thereby  determining  the yield  during the Fund's
holding period.  This arrangement  results in a fixed rate of return that is not
subject to market  fluctuations  during the Fund's holding period.  The value of
the collateral,  taken as a part of the repurchase agreement,  is at least equal
at all  times to the  total  amount  of the  repurchase  obligations,  including
interest.  In the event of counterparty  default,  the Fund has the right to use
the collateral to offset losses incurred. There is potential loss to the Fund in
the event the Fund is delayed or prevented from exercising its rights to dispose
of the collateral  securities,  including the risk of a possible  decline in the
value of the  underlying  securities  during the period  while the Fund seeks to
assert its rights. The Trust's Investment Adviser,  acting under the supervision
of the  Board  of  Trustees,  reviews  the  value  of  the  collateral  and  the
creditworthiness  of those  banks and  dealers  with which the Fund  enters into
repurchase agreements to evaluate potential risks.

     Securities transactions and investment income:  Securities transactions are
recorded as of the trade date. Realized gains and losses on investments sold are
recorded on the basis of  identified  cost.  Interest  income is recorded on the
accrual  basis.  Investment  income and realized  gains and losses are allocated
based upon the relative net assets of each class of shares.

     Expenses: Operating expenses directly attributable to a class of shares are
charged  to  that  class'  operations.   Expenses  of  the  Funds  not  directly
attributable  to the  operations of any class of shares are pro-rated  among the
classes to which the expense  relates  based on the  relative net assets of each
class of shares.

     Federal  income taxes:  The Funds have qualified and intend to qualify each
year as  regulated  investment  companies  pursuant to the  requirements  of the
Internal Revenue Code of 1986, as amended.  The Funds  distribute  substantially
all of their taxable income to their shareholders,  therefore, no Federal income
tax provision is required.

     Dividends and distributions to shareholders:  Dividends from net investment
income of each Fund are  determined  on a class level,  declared  daily and paid
monthly. The Funds do not expect to realize any net long-term capital gains and,
therefore, do not contemplate payments of any capital gains dividends.

     Income dividends and capital gain distributions,  if any, are determined at
fiscal year end in  accordance  with Federal  income tax  regulations  which may
differ from generally  accepted  accounting  principles.  These  differences are
primarily due to differing  treatments of income and gains on various investment
securities held by a Fund, timing differences and differing  characterization of
distributions made by a Fund as a whole.

3. SERVICE AGREEMENTS 

     Lehman Brothers acts as Distributor of the Trust's shares. Pursuant to Rule
12b-1  under the  Investment  Company Act of 1940,  as  amended,  the Funds have
adopted  either  Service  Agreements  or  Service  and  Distribution  Agreements
("Service  Agreements") with institutional  investors such as banks, savings and
loan  associations and other financial  institutions  ("Service  Organizations")
which  may  purchase  Class B,  Class C and Class E  shares.  Under the  Service
Agreements,  each Fund compensates  Service  Organizations for providing certain
services  to the  Funds  and  holders  of Class B,  Class C and  Class E shares.
Service  Agreement  fees are paid by each Fund based on the value of the average
daily net  assets of each  respective  class of  shares at the  annual  rates as
follows:  0.25% for the Class B shares,  0.35% for the Class C shares  and 0.15%
for the Class E shares.

4. SHARES OF BENEFICIAL INTEREST 

     The Trustees  have  authority  to issue an  unlimited  number of $0.001 par
value shares of beneficial interest currently divided into four classes for each
Fund,  except for the Cash  Management  Fund.  Since the Funds have sold shares,
issued  shares as  reinvestments  of  dividends  and  redeemed  shares only at a
constant net asset value of $1.00 per share, the number of shares represented by
such sales, reinvestments and redemptions is the same as the amounts shown below
for such transactions.

     The tables below summarize transactions of each class of shares, at $1.00:

5.   ORGANIZATION COSTS 

     The Funds bear all costs in connection  with their  organization  including
fees and expenses of registering  and qualifying  their shares for  distribution
under  Federal  and  state  securities  regulations.  All such  costs  are being
amortized  on the  straight-line  method  over a period of five  years  from the
commencement  of  operations  of each Fund. In the event that any of the initial
shares of a Fund are redeemed during such amortization  period, the Fund will be
reimbursed for any unamortized  organization costs in the same proportion as the
number of shares redeemed bears to the number of initial shares held at the time
of redemption.

7. SUBSEQUENT EVENT 

     On September 6, 1996, the Board of Trustees unanimously endorsed a proposal
(a) to combine three of the Funds with three  portfolios of a trust sponsored by
Federated  Investors  and (b) to change the  investment  advisor of three  other
Funds from LBGAM to Federated Management.  Each transaction requires shareholder
approval and will also involve the election of new Trustees of the Trust.

     With respect to the Prime Money Market Fund,  Prime Value Money Market Fund
and Municipal Money Market Fund,  shareholders will be asked to approve adoption
of a new investment advisory contract with Federated  Management,  an investment
advisory subsidiary of Federated Investors, and the election of the new Trustees
to the Trust.

     With  respect  to  Government   Obligations  Money  Market  Fund,  Treasury
Instruments Money Market Fund II, and Tax-Free Money Market Fund  (individually,
the  "Fund"),  shareholders  of each  Fund will be asked to  approve a  proposed
Agreement and Plan of Reorganization  between the Trust, on behalf of each Fund,
and Money Market  Obligations  Trust,  on behalf of one of its  portfolios  (the
"Portfolio"),  whereby a  Portfolio  of Money  Market  Obligations  Trust  would
acquire all of the assets of the  relevant  Fund in exchange  for  Institutional
Shares and  Institutional  Service Shares of the Portfolio to be distributed pro
rata by the Fund to holders of Class A Shares and Class B Shares,  respectively,
in complete liquidation of the Fund.
