Dear Shareholders:
 
    We  are pleased  to present the  Semi-Annual Report for  
the Lehman Brothers
Institutional Funds Group Trust  (the "Trust") for  the six-
month period  ending
July 31, 1994. This Report includes the portfolio holdings 
for each of the Money
Market and Fixed Income Funds that comprise the Trust, 
namely:
 
                               MONEY MARKET FUNDS
 
        - PRIME MONEY MARKET FUNDS
        Prime Money Market Fund
        Prime Value Money Market Fund
 
   
        - GOVERNMENT MONEY MARKET FUNDS
        Government Obligations Money Market Fund
        100% Government Obligations Money Market Fund (now 
"Cash
Management Fund")
        Treasury Instruments Money Market Fund II
        100% Treasury Instruments Money Market Fund
    
 
        - TAX-EXEMPT MONEY MARKET FUNDS
        Tax-Free Money Market Fund
        Municipal Money Market Fund
        California Municipal Money Market Fund
 
                               FIXED INCOME FUNDS
 
        - GOVERNMENT FIXED INCOME FUNDS
        Floating Rate U.S. Government Fund
        Short Duration U.S. Government Fund
 
RESPONDING TO A CHANGING RATE ENVIRONMENT
 
   
    The  new fiscal  year for the  Lehman Brothers 
Institutional  Funds began in
February amidst indications of strong  economic growth and 
concerns over  rising
inflation.  In an  effort to  moderate the  growth rate  and 
dampen inflationary
fears, the Federal Reserve Board tightened its monetary 
policy by increasing the
federal funds rate five times during the past six months. 
Indeed, as this letter
is being  written,  the Federal  Reserve  Board announced  
its  fifth  increase,
another  50 basis point  tightening, bringing aggregate  
federal funds increases
for the year to 175 basis points. Considering that interest 
rates had  generally
declined  over the past five years, the  speed and magnitude 
of this upward move
caused investors to  alter strategies and  corporate issuers 
to  scale back  new
issuance activity.
    
 
    In  managing the Funds  in this environment,  our 
primary focus  has been on
positioning the portfolios  to anticipate and  to take 
advantage  of the  higher
short-term  interest  rates,  while, with  respect  to the  
Money  Market Funds,
continuing to maintain a stable $1.00 per share net asset 
value. Fortunately, we
have met  this challenge  successfully  as several  of  the 
Money  Market  Funds
continue  to be among the performance  leaders in their 
respective categories as
reported in IBC/Donoghue's MONEY FUND REPORT.
 
   
    We take special pride in the fact that the Money Market 
Funds achieved these
results without using high  risk derivative instruments  
which have so  captured
the  attention  of  the  financial  press  and  securities  
regulators.  We have
maintained an investment strategy of not using the high risk 
derivatives because
we have viewed them as being beyond the spirit of Rule 2a-7, 
the SEC  regulation
governing a money market fund's ability to maintain a stable 
net asset value.
    
 
   
    We  are also pleased to  report that the Lehman  
Brothers Floating Rate U.S.
Government Fund and the Lehman Brothers Short Duration U.S. 
Government Fund have
produced solid  investment results  since they  were 
introduced  at the  end  of
March.  The total  return for  the three-month period  ended 
July  31, 1994, for
Floating Rate  U.S. Government  Fund  (Premier Class)  and 
Short  Duration  U.S.
Government  Fund  (Premier  and  Select  Class)  was  1.03%,  
1.21%  and  0.92%,
respectively.   While   we   acknowledge   that   these   
performance    records
    
 
                                       1
<PAGE>
   
cover  a period  of only  a few  months (and  are not  
necessarily indicative of
future performance),  as  with  our  Money  Market  Funds,  
these  results  were
accomplished without using high risk mortgage-backed 
derivative instruments.
    
 
COMBINING INVESTORS' NEEDS WITH OUR EXPERTISE -- SHORT 
DURATION MUNICIPAL FUND
 
   
    Matching  our  resources  with  our  investors'  needs  
is  central  to  our
philosophy.  Since  many  clients  have  expressed  an  
interest  in  tax-exempt
investment  products that  seek to provide  higher after-tax  
yields than fixed-
price money markets funds and with  minimal net asset value 
fluctuation, we  are
pleased  to announce that the Short Duration Municipal Fund 
will be available in
October, 1994.  The Fund  will be  managed  by our  talented 
team  of  portfolio
managers  and supported by  Lehman Brothers' Fixed  Income 
Research which placed
first in  INSTITUTIONAL INVESTOR  magazine's annual  "All-
American Fixed  Income
Research  Team"  poll  for  four years  from  1991  to 1994.  
When  the  Fund is
effective, your  Investor  Representative can  provide  you 
with  more  complete
information and a Prospectus which will contain management 
fees and expenses.
    
 
   
AN ENHANCEMENT TO OUR SERVICE DELIVERY . . . EXPRESSNET 
(LEX-SM-)
    
   
    In  our continuing effort to deliver the  highest 
quality service to you, we
enthusiastically announce the  introduction of our  new 
Windows-TM--based  order
entry system, EXPRESSNet (LEX-SM-), that allows you to trade 
directly on your PC
with  the Lehman  Brothers Institutional  Funds. With  LEX-
SM-, shareholders can
also  access  account  information   easily,  customize  
reports  and   retrieve
historical  yield  and dividend  information.  Your Investor  
Representative can
provide you with the information you will need to take 
advantage of LEX-SM-  and
trade directly on-line.
    
 
                                * * * * * * * *
 
    All  of us at Lehman Brothers trust that we will be able 
to continue to earn
your support and loyalty by providing you with superior 
investment products  and
services  . . . with a focus on quality in the prudent way 
we manage your assets

Clinton J. Kendrick                               Peter

Notes to Financial Statements (unaudited)
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
   
    Lehman   Brothers  Institutional   Funds  Group  Trust   
(the  "Trust")  was
established on November  25, 1992 as  a Massachusetts 
business  trust. It is  an
open-end  management investment company,  which consists of  
eleven funds: Prime
Money Market Fund, Prime Value  Money Market Fund, 
Government Obligations  Money
Market Fund, 100% Government Obligations Money Market Fund, 
Treasury Instruments
Money  Market Fund  II, 100%  Treasury Instruments  Money 
Market  Fund, Tax-Free
Money Market  Fund,  Municipal Money  Market  Fund, 
California  Municipal  Money
Market  Fund,  (collectively  the  "Money  Market  Funds"),  
Floating  Rate U.S.
Government Fund and Short Duration U.S. Government Fund (the 
"Funds"). All Money
Market Funds currently offer four classes of shares: Class 
A, Class B, Class  C,
and  Class E.  The Prime Value  Money Market Fund,  
Government Obligations Money
Market Fund and Municipal  Money Market Fund offered  Class 
D shares to  certain
individual  investors.  As of  March 28,  1994,  Class D  
shares were  no longer
offered. The Floating  Rate U.S.  Government Fund  and the  
Short Duration  U.S.
Government  Fund  currently  offer two  classes  of shares:  
Premier  and Select
shares. Class A shares  and Premier shares are  sold to 
institutional  investors
that  have not entered into servicing agreements.  Class B, 
Class C, Class E and
Select shares bear service fees. All classes of shares have 
identical rights and
privileges except  that Class  B, Class  C, Class  E and  
Select shares  possess
certain  exclusive voting rights on matters relating to 
their respective service
fees. As of July 31, 1994, the Board of Trustees had 
authorized the issuance  of
a third class of shares for the Floating Rate U.S. 
Government Fund and the Short
Duration  U.S. Government Fund which are designated for 
individual investors. As
of July 29, 1994, shares of the  Treasury Instruments Money 
Market Fund were  no
longer  sold to the public. 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  Money Market 
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.
    
 
   
    For the  Floating Rate  U.S. Government  Fund and  the 
Short  Duration  U.S.
Government  Fund, portfolio securities  for which market  
quotations are readily
available will be valued on the basis of quotations provided 
by dealers in  such
securities  or furnished  by a pricing  service. Portfolio  
securities for which
market quotations are not readily available  and other 
assets will be valued  at
fair  value using  methods determined  in good  faith by  
the Investment Adviser
under the supervision  of the Trustees  and may include  
yield equivalents or  a
pricing  matrix. Short-term obligations  having 60 days or  
less to maturity are
valued at amortized cost.
    
 
   
    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, the
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 Fund's Investment Adviser and 
Administrator, 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 Funds enter
into repurchase agreements to evaluate potential risks.
    
 
    FUTURES CONTRACTS:   The Floating Rate  U.S. Government 
Fund  and the  Short
Duration  U.S. Government Fund may engage in futures 
transactions. Upon entering
into a futures  contract, the Fund  is required  to deposit 
with  the broker  an
amount of cash or cash equivalents equal to a certain 
percentage of the contract
amount. This

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
   
is  known as the "initial margin."  Subsequent payments 
("variation margin") are
made or received by the Fund each day, depending on the 
daily fluctuation of the
value of  the  contract. The  daily  changes in  the  
contract are  recorded  as
unrealized gains or losses. The Fund recognizes a realized 
gain or loss when the
contract is closed.
    
 
    There are several risks in connection with the use of 
futures contracts as a
hedging  device.  The  change  in  the  value  of  futures  
contracts  primarily
corresponds with  the  value of  their  underlying 
instruments,  which  may  not
correlate  with the change in the value  of the hedged 
instruments. In addition,
there is the risk the Fund may not  be able to enter into a 
closing  transaction
because of an illiquid secondary market.
 
    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 and  
unrealized 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  
prorated among the
classes to which the expense  relates based on the  relative 
net assets of  each
class of shares.
    
 
    FEDERAL  INCOME TAXES:  The Funds  intend to qualify as 
regulated investment
companies by complying  with the requirements  of the 
Internal  Revenue Code  of
1986,  as  amended  and  applicable to  regulated  
investment  companies  and by
distributing 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 and are 
declared daily  and
paid  monthly. The Money Market Funds do not expect to 
realize any net long-term
capital gains and  therefore do not  contemplate payments of  
any capital  gains
dividends. Net capital gain distributions, if any, will be 
made annually for the
Floating Rate U.S. Government Fund and the Short Duration 
U.S. Government Fund.
    
 
   
    Income dividends and capital gain distribution are 
determined at fiscal year
end  in accordance with  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  the
Fund, timing differences and differing characterization of 
distributions made by
the Fund as a whole.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
   
Lehman Brothers. As of July 31, 1994, the Floating Rate U.S. 
Government Fund had
issued ten Select shares in  the amount of $100  to Lehman 
Brothers Inc.  During
the six months ended July 31, 1994, there was no income or 
expenses allocated to
Class B, Class C, Class D, Class E and Select shares that 
did not have activity.
    
 
6. 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  the Fund. In  the event that  
any of the initial
shares of the 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. CONCENTRATION OF CREDIT
 
    The  California  Municipal  Money  Market  Fund  
primarily  invests  in debt
obligations issued by the  State of California  and its 
political  subdivisions,
agencies and public authorities to obtain funds for various 
public purposes. The
Fund  is more susceptible  to factors adversely  affecting 
issuers of California
municipal securities  than  is  a  municipal  money  market  
fund  that  is  not
concentrated in these issuers to the same extent.
 
   
8. SUBSEQUENT EVENTS
    
   
    As  of August 3,  1994, the Board  of Trustees 
authorized  the issuance of a
fifth and  sixth class  of shares,  Select shares  and 
Global  Clearing  shares,
respectively,   for  the  Government  Obligations  Money  
Market  Fund  and  the
California Municipal Money Market Fund.
    
 
   
    As of August  26, 1994, the  100% Government Obligations  
Money Market  Fund
changed  its  name  to the  Cash  Management  Fund and  
changed  certain  of its
investment policies and limitations.
    
 
   
    As of October 3,  1994, the Trust  will begin offering a  
new Fund, the  New
York Municipal Money Market Fund.
