     Set  forth  in the  chart below  is  performance data  provided by  SBAM AP
relating, (i) for the  period from January  1, 1992 to February  28, 1995, to  a
non-U.S.  collective investment vehicle  (the 'Offshore Fund  I') managed by the
portfolio manager of the Asia Growth Fund  while he was employed by a  different
investment adviser unaffiliated with SBAM (ii) for the quarters ending September
30,  1995,  December 31,  1995  and March  31,  1996, to  a  non-U.S. collective
investment vehicle  managed  by  the portfolio  manager  after  commencement  of
employment  with an affiliate of SBAM (the 'Offshore Fund II') and (iii) for the
quarters ending  June  30,  1996  and   September  30,  1996,  to  a   composite
('Composite')  consisting of Offshore  Fund II and  Salomon Brothers Asia Growth
Fund ('Retail Asia Growth Fund'), a  portfolio of Salomon Brothers Series  Funds
Inc,  a U.S. registered investment company. The Retail Asia Growth Fund and Asia
Growth Fund  have  the same  portfolio  manager and  have  identical  investment
objectives,  policies and strategies. Both Offshore  Fund I and Offshore Fund II
have  substantially  similar,  though  not  identical,  investment   objectives,
policies  and strategies as those of the  Fund. With respect to Offshore Fund I,
the period  shown  reflects the  period  for  which the  portfolio  manager  was
primarily responsible for the day-to-day management of the portfolio of Offshore
Fund I. During the period shown for Offshore Fund I, the size of the fund ranged
from approximately $45 million to $95 million and during the period shown solely
for  Offshore Fund II, the size of the fund ranged from approximately $8 million
to $10 million.  During the  period shown  for the  Composite, the  size of  the
Composite ranged from approximately $10 million to $18.5 million.

index is  composed  of  a sample of companies  from the following ten countries:
Hong  Kong, India, Indonesia, Korea, Malaysia, Pakistan, Philippines, Singapore,
Sri Lanka and Thailand. Constituent  stocks are  selected for the  index on  the
basis  of industry  representation, liquidity and sufficient float. The index is
unmanaged  and accordingly, does not  reflect the effect  of operating expenses,
including  advisory fees,  transaction  costs   and  other  expenses   but  does
reflect reinvestment of dividends.

     The performance data  shown below should  be read in  conjunction with  the
information in 'General' that follows:

* This  figure is a weighted-average figure, representing,  for  the period from
  September 1, 1995 to April 30, 1996, total return of Offshore Fund II, and for
  the period May 1, 1996 to September 30, 1996, for the Composite.

     General.  The performance  results shown above  are based  on total returns
reflecting realized and unrealized gains  and losses and income, including  that
derived from cash positions. Returns are calculated monthly for Offshore Fund I,
Offshore Fund II and the Retail Asia Growth Fund and are compounded monthly. The
investment results are time-weighted  on a daily basis and market-weighted based
on  market  values determined as of the first business day of  each  month.  The
performance results  are  net  of  transaction costs and advisory and other fees
incurred and  reflect reinvestment of dividends and capital gains distributions,
if any.

     The performance results  shown above  are not performance  results for  the
Asia  Growth  Fund,  which  has  recently  commenced  investment operations. The
results shown above should not be deemed to be indicative of
    
 
                                       3

future results  for the  Asia  Growth Fund  owing  to differences  in  brokerage
commissions  and dealer  spreads, expenses, including  investment advisory fees,
the size of positions taken  in relation to fund  size, timing of purchases  and
sales  and market conditions at the time  of a transaction, timing of cash flows
and availability of cash for new investments.

     Although substantially  similar, the  investment objectives,  policies  and
strategies  for Offshore Fund I and Offshore Fund  II differ in certain respects
from  those  of  the  Asia  Growth Fund. In addition, such accounts were and are
managed  without   regard  to  certain   tax  requirements  applicable  to  U.S.
registered  investment companies that limit  the proportions of short-term gains
that such companies may  realize to maintain their  tax status. See  'Dividends,
Distributions  and Taxes.' Accordingly, the  performance results shown above and
that of the Asia Growth Fund are expected to differ.

SALOMON BROTHERS INSTITUTIONAL SERIES FUNDS INC
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------
    
 
   
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

The Salomon Brothers Institutional High Yield Bond Fund (the 'High Yield Bond
Fund'), Salomon Brothers Institutional Asia Growth Fund (the 'Asia Growth Fund')
and Salomon Brothers Institutional Emerging Markets Debt Fund (the 'Emerging
Markets Debt Fund') are portfolios of the Salomon Brothers Institutional Series
Funds Inc (the 'Institutional Series'). The High Yield Bond Fund and the Asia
Growth Fund (each, a 'Fund' and collectively, the 'Funds') are included in this
report. The Emerging Markets Debt Fund has not commenced investment operations
and is therefore not included in this report. The Institutional Series is an
open-end investment company incorporated in Maryland on January 19, 1996. Each
Fund has a specific investment objective: the High Yield Bond Fund's objective
is to maximize total return by investing primarily in a portfolio of high yield
fixed-income securities that offer a yield above that generally available on
debt securities in the four highest rating categories of the recognized rating
services; the Asia Growth Fund's objective is to seek long-term capital
appreciation.

The following is a summary of significant accounting policies followed by the
Institutional Series in the preparation of its financial statements. The
policies are in conformity with generally accepted accounting principles
('GAAP'). The preparation of financial statements in accordance with GAAP
requires management to make estimates of certain reported amounts in the
financial statements. Actual amounts could differ from those estimates.

     (A) INVESTMENT VALUATION. Portfolio securities listed or traded on national
     securities exchanges, or reported on the NASDAQ national market system, are
     valued at the last sale price, or if there have been no sales on that day,
     at the mean of the current bid and asked price which represents the current
     value of the security. Over-the-counter securities are valued at the mean
     of the current bid and asked price. Debt securities are valued by using
     either market quotations or independent pricing services which use prices
     provided by market-makers or estimates of market values obtained from yield
     data relating to instruments or securities with similar characteristics.
     Publicly traded sovereign bonds are typically traded internationally on the
     over-the-counter market and are valued at the mean of the last current bid
     and asked price as of the close of business of that market. Short-term
     securities with less than 60 days remaining to maturity when acquired by a
     Fund will be valued at amortized cost which approximates market value. If a
     Fund acquires such securities with more than 60 days remaining to maturity,
     they will be valued at current market value (using the bid price), until
     the 60th day prior to maturity, and will then be valued on an amortized
     cost basis.

     Prior governmental approval for foreign investments may be required under
     certain circumstances in some emerging countries, and the extent of foreign
     investment in domestic companies may be subject to limitation in other
     emerging countries. Foreign ownership limitations also may be imposed by
     the charters of individual companies in emerging countries to prevent,
     among other things, violation of foreign investment limitations. As a
     result, an additional class of shares (identified as 'Foreign Shares' in
     the Portfolio of Investments) may be created and offered for investment by
     such companies. The 'local' and 'foreign' shares' market values may differ.

     Foreign securities quoted in a foreign currency are translated into U.S.
     dollars using exchange rates at 2:30 p.m. Eastern time (12:30 p.m. for the
     Asia Growth Fund), or at such other rates as Salomon Brothers Asset
     Management ('SBAM') may determine to be appropriate in computing net asset
     value.

     Securities for which reliable quotations or prices from pricing services
     are not readily available (as may be the case for securities of limited
     marketability) and all other assets are valued at their respective fair
     value as determined in good faith by, or under procedures established by,
     the Board of Directors.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------
 
   
     (B) OPTION CONTRACTS. When a Fund writes or purchases a call or a put
     option, an amount equal to the premium received or paid by the Fund is
     recorded as a liability or asset, the value of which is marked-to-market
     daily to reflect the current market value of the option. When the option
     expires, the Fund realizes a gain or loss equal to the amount of the
     premium received or paid. When the Fund exercises an option or enters into
     a closing transaction by purchasing or selling an offsetting option, it
     realizes a gain or loss without regard to any unrealized gain or loss on
     the underlying security. When a written call option is exercised, the Fund
     realizes a gain or loss from the sale of the underlying security and the
     proceeds from such sale are increased by the premium originally received.
     When a written put option is exercised, the amount of the premium received
     reduces the cost of the security that the Fund purchased upon exercise of
     the option.

     (C) REPURCHASE AGREEMENTS. When entering into repurchase agreements, it is
     each Fund's policy that the Fund take possession, through its custodian, of
     the underlying collateral and monitor the collateral's value at the time
     the agreement is entered into and on a daily basis during the term of the
     repurchase agreement to ensure that it equals or exceeds the repurchase
     price. In the event of default or bankruptcy by the other party to the
     agreement, realization and/or retention of the collateral may be subject to
     legal proceedings.

     (D) FOREIGN CURRENCY TRANSLATION. The accounting records of each Fund are
     maintained in U.S. dollars. Investment securities and other assets and
     liabilities of the Funds denominated in a foreign currency are translated
     into U.S. dollars at the prevailing rates of exchange each day. Purchases
     and sales of securities, income receipts and expense payments are
     translated into U.S. dollars at the prevailing exchange rate on the
     respective dates of the transactions. Net realized gains and losses on
     foreign currency transactions represent net gains and losses from sales and
     maturities of forward currency contracts, disposition of foreign
     currencies, currency gains and losses realized between the trade and
     settlement dates on securities transactions and the difference between the
     amount of net investment income accrued and the U.S. dollar amount actually
     received. The effect of changes in foreign currency exchange rates on
     investments in securities are not segregated in the Statements of
     Operations from the effects of changes in market prices of those
     securities, but are included with the net realized and unrealized gain or
     loss on investments.

     (E) FORWARD FOREIGN CURRENCY CONTRACTS. Each Fund may enter into forward
     foreign currency contracts in connection with planned purchases or sales of
     securities or to hedge the value of portfolio securities. A forward foreign
     currency contract is an agreement between two parties to buy and sell a
     currency at a set price on a future date. The contract is marked-to-market
     daily and the change in value is recorded by the Fund as an unrealized gain
     or loss. When a forward foreign currency contract is extinguished, through
     either delivery or offset by entering into another forward foreign currency
     contract, the Fund records a realized gain or loss equal to the difference
     between the value of the contract at the time it was opened and the value
     of the contract at the time it was extinguished or offset.

     (F) FEDERAL INCOME TAXES. Each Fund intends to comply with the requirements
     of the Internal Revenue Code applicable to regulated investment companies
     by distributing all of its income, including any net realized gains, to
     shareholders. Therefore, no Federal income tax or excise tax provision is
     required.

     (G) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Each Fund will declare
     dividends from net investment income annually. Distributions of net
     realized gains to shareholders of each Fund, if any, are declared at least
     annually. Dividends and distributions to shareholders of each Fund are
     recorded on the ex-dividend date and are determined in accordance with
     income tax regulations which may differ from GAAP primarily due to
     differences in the treatment of foreign currency gains/losses, deferral of
     wash sales, and post-October losses incurred by each
    
 
                                       15

     Fund. Permanent book/tax differences are reclassified within the capital
     accounts based on their federal income tax basis treatment; temporary
     differences do not require reclassifications. Dividends and distributions
     which exceed net investment income and net realized gains for financial
     reporting purposes but not for tax purposes are reported as dividends in
     excess of net investment income and distributions in excess of net realized
     capital gains.

     (H) EXPENSES. Direct expenses are charged to the Fund that incurred them,
     and general expenses of the Institutional Series are allocated to the Funds
     based on each Fund's relative net assets.

     (I) ORGANIZATIONAL COSTS. Certain costs incurred in connection with each
     Fund's organization have been deferred and are being amortized by the Funds
     over a 60 month period from the date each Fund commenced investment
     operations.

     (J) OTHER. Investment transactions are recorded as of the trade date.
     Dividend income is recorded on the ex-dividend date or on a when-known
     basis. Interest income, including the accretion of discounts or
     amortization of premiums, is recognized when earned. Gains or losses on
     sales of securities are calculated for financial accounting and Federal
     income tax purposes on the identified cost basis.

2. MANAGEMENT FEE AND OTHER AGREEMENTS

Each Fund retains SBAM, an indirect wholly owned subsidiary of Salomon Inc, to
act as investment manager of each Fund, subject to the supervision by the Board
of Directors of the Institutional Series. Among other things, SBAM furnishes the
Funds with office space and certain services and facilities required for
conducting the business of the Funds, and pays the compensation of its officers.
The management fee for these services for each Fund is payable monthly and is
based on the following annual percentages of each Funds' average daily net
assets: .50% for the High Yield Bond Fund and .75% for the Asia Growth Fund.
SBAM has retained Salomon Brothers Asset Management Asia Pacific Limited ('SBAM
AP'), an affiliate of SBAM, to act as sub-advisor to the Asia Growth Fund. SBAM
AP is compensated by SBAM at no additional expense to the Asia Growth Fund.
Salomon Brothers Asset Management Limited ('SBAM Limited'), an affiliate of
SBAM, provides certain administrative services to the Asia Growth Fund. For such
administrative services, SBAM Limited is compensated by SBAM at no additional
expense to the Asia Growth Fund.

If in any fiscal year total expenses of any Fund, excluding taxes, interest,
brokerage and extraordinary expenses, but including the management fee, exceed
the most stringent expense limitation imposed by state securities regulations
applicable to each Fund, SBAM will pay or reimburse the Funds for the excess.
Currently, this limitation on an annual basis is 2.5% of the first $30 million
of average daily net assets, 2.0% of the next $70 million of average daily net
assets and 1.5% of average daily net assets in excess of $100 million. For the
period ended August 31, 1996, there was no such reimbursement. However, SBAM has
voluntarily agreed to waive its management fees and absorb a portion of expenses
to the extent that each Fund's operating expense ratio exceeds, on an annual
basis, .55% and 1.00% of average daily net assets for the High Yield Bond Fund
and Asia Growth Fund, respectivley. For the period ended August 31, 1996, SBAM
waived management fees of $4,179 and $6,681 for the High Yield Bond Fund and
Asia Growth Fund, respectively, and voluntarily absorbed expenses of $83,409 and
$85,596 for the High Yield Bond Fund and Asia Growth Fund, respectively.

Investors Bank & Trust Company ('IBT') serves as custodian, transfer agent and
administrator for each Fund, which includes performing certain administrative
services in connection with the operation of each Fund. IBT has agreed to waive
a portion of its custody fees until October 31, 1996. In addition, a credit is
earned on outstanding cash balances held by the custodian during

were waived by IBT for each Fund and credits of $875 and $659 were earned on
outstanding cash balances for the High Yield Bond Fund and the Asia Growth Fund,
respectively.

5. PORTFOLIO INVESTMENT RISKS

CREDIT AND MARKET RISK. Funds that invest in high yield instruments are subject
to certain credit and market risks. The yields of high yield debt obligations
reflect, among other things, perceived credit risk. The Funds' investment in
securities rated below investment grade typically involve risks not associated
with higher rated securities including, among others, greater risk of timely and
ultimate payment of interest and principal, greater market price volatility and
less liquid secondary market trading. The consequences of political, social,
economic or diplomatic changes may have

disruptive effects on the market prices of investments held by the Funds. The
Funds' investment in non-dollar denominated securities may also result in
foreign currency losses caused by devaluations and exchange rate fluctuations.

FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK. Both Funds may enter into
forward foreign currency contracts ('forward contracts') to facilitate
settlement of foreign currency denominated portfolio transactions or to manage
foreign currency exposure associated with foreign currency denominated
securities. Forward contracts involve elements of market risk in excess of the
amounts reflected in the Statements of Assets and Liabilities. The Funds bear
the risk of an unfavorable change in the foreign exchange rate underlying the
forward contract. Risks may also arise upon entering into these contracts from
the potential inability of the counterparties to meet the terms of their
contracts.

Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of U.S. dollar denominated
transactions as a result of, among other factors, the possibility of lower
levels of governmental supervision and regulation of foreign securities markets
and the possibility of political or economic instability.

The High Yield Bond Fund may invest in instruments whose values and interest
rates may be linked to foreign currencies, interest rates, indices or some other
financial indicator. The value at maturity or interest rates for these
instruments will increase or decrease according to the change in the indicator
to which it is indexed. These securities are generally more volatile in nature
and the risk of loss of principal is greater.

A risk in writing a covered call option is that the Fund may forego the
opportunity of profit if the market price of the underlying security increases
and the option is exercised. A risk in writing a put option is that the Fund may
incur a loss if the market price of the underlying security decreases and the
option is exercised. In addition, there is the risk that the Fund may not be
able to enter into a closing transaction because of an illiquid secondary
market.

SALOMON BROTHERS INSTITUTIONAL SERIES FUNDS INC
NOTES TO FINANCIAL STATEMENTS -- (UNAUDITED)
- --------------------------------------------------------------------------------
 
   
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
    
 
   
Salomon Brothers Series Funds Inc (the 'Company') was incorporated in Maryland
on April 17, 1990 as an open-end management investment company, and currently
operates as a series company comprised of ten portfolios: Salomon Brothers Cash
Management Fund (the 'Cash Management Fund'), Salomon Brothers New York
Municipal Money Market Fund, (the 'New York Municipal Money Fund'), Salomon
Brothers Institutional Money Market Fund (the 'Fund'), Salomon Brothers New York
Municipal Bond Fund (the 'New York Municipal Bond Fund'), Salomon Brothers
National Intermediate Municipal Fund (the 'National Intermediate Municipal
Fund'), Salomon Brothers U.S. Government Income Fund (the 'U.S. Government
Income Fund'), Salomon Brothers High Yield Bond Fund (the 'High Yield Bond
Fund'), Salomon Brothers Strategic Bond Fund (the 'Strategic Bond Fund'),
Salomon Brothers Total Return Fund (the 'Total Return Fund'), and Salomon
Brothers Asia Growth Fund (the 'Asia Growth Fund'). The Fund is included in this
report. The Fund changed its name from Salomon Brothers U.S. Treasury Securities
Money Market Fund to its current name on April 29, 1996. Prior to April 29,
1996, the Fund's objective was to seek a high level of current income by
investing only in short-term United States government and government agency
securities. The Fund's current objective is to seek as high a level of current
income as is consistent with liquidity and the stability of principal. The Cash
Management Fund, New York Municipal Money Fund, New York Municipal Bond Fund,
National Intermediate Municipal Fund, U.S. Government Income Fund, High Yield
Bond Fund, Strategic Bond Fund, Total Return Fund, and Asia Growth Fund are
reported in separate reports and are not included herein.
    
 
   
Following  is a summary of significant  accounting policies followed by the Fund
in the preparation of its financial  statements. The policies are in  conformity
with  generally  accepted  accounting principles  ('GAAP').  The  preparation of
financial statements  in  accordance  with  GAAP  requires  management  to  make
estimates  of  certain  reported  amounts in  the  financial  statements. Actual
amounts could differ from those estimates.
    
 
   
     (A) SECURITIES VALUATION. Portfolio securities are valued using the
     amortized cost method, which involves initially valuing an investment at
     its cost and thereafter assuming a constant amortization to maturity of any
     premium or discount. This method results in a value approximating market
     value and does not include unrealized gains or losses.
    
 
   
     (B) FEDERAL INCOME TAXES. The Fund has complied and intends to continue to
     comply with the requirements of the Internal Revenue Code applicable to
     regulated investment companies, including the distribution requirements of
     the Tax Reform Act of 1986, and to distribute all of its income, including
     any net realized gains, to shareholders. Therefore, no Federal income tax
     or excise tax provision is required.
    
 
   
     (C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends on the shares of
     the Fund are declared each business day to shareholders of record at twelve
     noon (New York time) on that day, and paid on the last business day of the

     (E) OTHER.  Investment transactions  are  recorded as  of the  trade  date.
     Interest  income, including the accretion  of discounts or the amortization

     securities are calculated on the identified cost basis.
    
 
   
2. MANAGEMENT FEE AND OTHER AGREEMENTS
    
 
   
The Company retains Salomon Brothers Asset Management Inc ('SBAM'), an indirect
wholly owned subsidiary of Salomon Inc, to act as investment manager of the
Fund, subject to the supervision by the Board of Directors of the Company. SBAM
furnishes the Company with office space and certain services and facilities
required for conducting the business of the Company and pays the compensation of
its officers. The management fee for these services is payable monthly and is
based on an annual rate of .20% of the Fund's average daily net assets. Prior to
April 29, 1996, the management fee was based on an annual rate of .10% of the
Fund's average daily net assets.
    
 
   
If in any fiscal year total expenses of the Fund, excluding taxes, interest,
brokerage and extraordinary expenses, but including the management fee, exceed
the most stringent expense limitations imposed by state securities regulations
applicable to the Fund, SBAM will pay or reimburse the Fund for the excess.
Currently, the most restrictive of these limitations on an annual basis is 2.5%
of the first $30 million of average daily net assets, 2.0% of the next $70
million of average daily net assets and 1.5% of average daily net assets in
excess of $100 million. No such expense reimbursement was required for the six
months ended June 30, 1996.
    
 
   
Under a voluntary agreement between SBAM and the Fund, SBAM has agreed to reduce
or otherwise limit the expenses of the Fund (exclusive of taxes, interest and
extraordinary expenses such as litigation and indemnification expenses), on an
annualized basis, to .18% of the Fund's average daily net assets for a period
ending April 29, 1997, and to no more than .25% thereafter. For the six months
ended June 30, 1996, SBAM voluntarily waived management fees of $5,522 and
voluntarily absorbed $18,542 of expenses.
    
 
   
Investors Bank & Trust Company serves as custodian, administrator and
shareholder servicing agent for the Fund, which includes performing custodial
and certain administrative services in connection with the operation of the
Fund. During the six months ended June 30, 1996, custodian fees were reduced by
$266 for the Fund, relating to credits earned on cash balances held by the
custodian.
    
 
   
The Fund has an agreement with Salomon Brothers Inc to distribute its shares.
    
 
   
3. CAPITAL STOCK
    
 
   
At June 30, 1996, the Company had 10,000,000,000 shares of authorized capital
stock, par value $.001 per share, of which the Fund had 1,000,000,000 shares
authorized.

4. PORTFOLIO ACTIVITY
    
 
   
The Fund invests in money market instruments maturing in thirteen months or less
whose short-term credit ratings are within the two highest ratings categories of
two nationally recognized statistical rating organizations ('NRSROs') or if
rated by only one NRSRO, that NRSRO, or, if not rated, are believed by the
investment manager to be of comparable quality.
    
 
   
At December 31, 1995, the Fund had $176 in net capital loss carry-forwards
expiring in 2002 available to offset future capital gains.

ITEM 27. INDEMNIFICATION
 
     Reference is made to Article VII of Registrant's Articles of Incorporation,
Article V of Registrant's By-Laws and  Section 4 of the Distribution  Agreements
between the Registrant and Salomon Brothers Inc.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of  1933,  as amended  (the 'Securities  Act'), may  be permitted  to directors,
officers and controlling  persons of  the Registrant pursuant  to the  foregoing
provisions,  or otherwise, the Registrant understands that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in  the Securities  Act and  is, therefore,  unenforceable. In  the
event  that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the  Registrant in the successful  defense of any  action,
suit  or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will,  unless
in  the  opinion of  its  counsel the  matter  has been  settled  by controlling
precedent, submit to a  court of appropriate  jurisdiction the question  whether
such  indemnification  by  it  is  against public  policy  as  expressed  in the
Securities Act and will be governed by the final adjudication of such issue.
 
ITEM 28. BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER
 
     The list required by  this Item 28  of officers and  directors of SBAM  and
SBAM  AP,  together  with  information as  to  any  other  business, profession,
vocation or employment of a substantial  nature engaged in by such officers  and
directors during the past two years, is incorporated by reference to Schedules A
