To Our Shareholders
 
This report contains a special performance review for each fund other than the
Cash Management Fund. We are very pleased with the aggregate performance of the
Investment Series Funds and our goal is to continue to reward shareholders with
high quality investment performance over time. One of the best ways to measure
our progress toward this goal is to compare the performance of our funds with
like funds. In the following pages, you can see how each of the Salomon Brothers
Investment Series Funds (other than Cash Management Fund and the Asia Growth
Fund) ranks within a universe of similar funds as compiled by Lipper Analytical
Services, a leading mutual fund rating service. (See pp. 3, 5, 7, 9, 13, 15 and
17.)
 
FINANCIAL MARKET RETURNS
During the first half of 1996 the stock market, as portrayed by the S&P 500
returned 10.1%. While off the pace of 1995, market performance was still strong.
The high grade bond markets (corporates, mortgages and governments) declined
1.3% as measured by the Salomon Brothers Broad Investment Grade Index. The
municipal bond market fared better than their high grade taxable counterparts
declining 0.5% as measured by the Lehman Municipal Bond Index. High yield and
emerging markets debt had positive performances, up 2.9% as measured by the
Salomon Brothers High Yield Market Index and 14.0% as measured by the Salomon
Brothers Brady Bond Index, respectively. Check your fund's individual
performance on the following pages.
 
THE ECONOMY
The current economic expansion is now 61 months old. This is the third longest
expansion in the post war era. At this point in the economic expansion, with a
low rate of unemployment at 5.3%, financial markets are generally fearful of
signs that inflation will begin to rise. During the first six months of 1996,
the rise of energy prices, grain prices and wages caused the long government
bond market to react quite poorly with interest rates rising from 6% to 7 1/4%.
However, the Federal Reserve did not tighten credit and the long bond market
calmed somewhat by the end of June.
 
Corporate profits, while slowing somewhat from the hectic expansion of 1994 and
1995, continued to show above average growth. Some of the more cyclical areas of
the economy such as paper, chemicals, metals and technology are showing lower
profitability. Other areas such as energy, financial services, retail and real
estate showed very strong growth in profitability. The stock market focused on
profits and rose despite the negative influence of the higher interest rates.
Likewise, the high yield bond market prospered as buoyant profits improved
corporate credit.
 
Looking ahead to the second half of 1996, we believe the economy will moderate
its growth rate. However, due to the advanced age of the economic cycle,
investors and the 'Fed' could react badly to any upward revisions in economic
growth or inflation rates. As a result any further acceleration in economic
activity is likely to be met by an increase in market volatility.
 
STRATEGY
The stock market has had a tremendous run up in price the last two years due to
strong profitability and preference among investors for stocks as opposed to
debt instruments. With both the economic and stock market cycles well advanced,
we are becoming risk averse and selective in our investment process. There has
been heavy speculation in many unseasoned areas and dividend yields are very
low, a situation in which shortfalls from expectations can be severely punished.
 
The debt markets have shown unusually disparate performance to date in 1996. The
high grade debt market is fearful of rising inflation typical of late stages of
economic cycles. Thus, we have been limiting our exposure to the risk of rising
interest rates and, have been more heavily weighting mortgage-backed and
corporate securities. The high yield market is benefiting from high earnings
levels which tends to improve the perception of credit ratings. Emerging markets
debt has experienced very positive returns as growth accelerates in emerging
economies after the credit crisis of 1993 and 1994.
 
OUR NEWEST ADDITION
Recognizing the need to offer our clients more diversified opportunities outside
the U.S., a new portfolio, the Asia Growth Fund, was added to the Salomon
Brothers Investment Series on April 29, 1996. We are excited by the addition of
this unique investment opportunity to the Salomon Brothers Investment Series and
we encourage you to read the market overview on page 10 provided by Mr.
Guarnieri, portfolio manager of this Fund.
 
At Salomon Brothers Asset Management Inc, we appreciate the confidence you have
shown in our family of funds and we intend to do everything we can to earn your
trust in the future. If you have any questions about the Salomon Brothers
Investment Series, or if you'd like a prospectus containing more information on

   SALOMON BROTHERS HIGH YIELD BOND FUND

Peter J. Wilby
                   MEET YOUR FUND MANAGER
                   Peter J. Wilby, Managing Director and Portfolio Manager at
                   Salomon Brothers Asset Management Inc, has 13 years of
                   experience managing high yield and emerging market debt
                   securities. Mr. Wilby is primarily responsible for day-to-day
                   Fund management.
 
                   INVESTMENT OBJECTIVE
                   To maximize current income by investing primarily in a
                   diversified portfolio of high yield, fixed income securities
                   rated in medium or lower categories. As a secondary
                   objective, the Fund seeks capital appreciation.
 
 
   INVESTMENT STRATEGY
   Under normal market conditions, the Fund intends to invest at least 65% of
   its assets in securities rated Baa or lower by Moody's Investors Services,
   Inc., or those rated BBB or lower by Standard & Poor's Corporation. A key
   component of the overall strategy is to seek to determine the optimal asset
   allocation between domestic high yield bonds and foreign fixed income
   securities such as Brady Bonds and lower-rated sovereign debt.
 
   MARKET REVIEW
   The High Yield Bond Fund continues to complement its portfolio by including
   exposure to emerging markets debt. This allocation, carefully monitored and
   re-evaluated as market conditions change, is a leading contributor to the
   strong relative performance of the High Yield Bond Fund versus other high
   current yield funds.
 
   In the higher-yielding sectors during the past several months, emerging debt
   markets were focused on the presidential election in Russia. As expected
   Boris Yeltsin, the pro-reform, free market candidate was re-elected,
   continuing the trend of positive political developments in emerging market
                    countries. In other areas, fundamental economic developments
                    have been very positive in Argentina and Mexico, as both
                    countries struggle to recover from deep recessions.
     [GRAPH]
                    In the U.S. corporate high-yield sector, spreads have
                    tightened slightly over Treasuries, and mutual fund inflows
                    have been high. The market has been stable, with heavy new
                    issue activity (including refinancings) and we expect yield
                    spreads over Treasuries to remain near current levels. Our
                    fundamental outlook is unchanged and we continue to believe
                    that selective buying is the best approach in this market.

                   affliate, Salomon Brothers Asset Management Limited, has 13
                   years of experience managing fixed income securities. Mr.
                   Scott is responsible for day to day management of certain
                   portions of the Fund's portfolio.
 
                   INVESTMENT OBJECTIVE
                   To seek a high level of current income. As a secondary
                   objective, the Fund seeks capital appreciation.
 

 
   INVESTMENT STRATEGY
   The Fund seeks to achieve its objective by investing in a globally diverse
   portfolio of fixed income instruments and by giving the investment manager
   broad discretion to deploy the Fund's assets among certain segments of the
                    fixed-income market that the investment manager believes
                    will contribute to the achievement of the Fund's objectives.
                    Assets of the Strategic Bond Fund may be deployed among
                    various sectors of the global fixed income market, depending
                    on the portfolio managers' analyses of current economic and
                    market conditions and the relative risks and opportunities
                    presented in various market segments.
 
                    MARKET REVIEW
                    Our investment process -- which is focused on identifying
                    and capturing relative value between global fixed income
                    markets -- led us to maintain the Fund's weightings
                    throughout the first half of 1996, with approximately
                    22% of the portfolio invested in emerging market debt and
                    48% invested in high yield securities. This allocation
                    generated highly favorable investment results, as the Fund
                    ranked near the top compared with other multi-sector bond
                    funds.
 [GRAPH]
                    Credit quality in the high yield bond market generally
                    continues to improve, as many U.S. corporations are using
                    higher earnings to pay down debt and strengthen their
                    balance sheets. We also continue to take a positive view of
                    opportunities in the emerging market debt sector, with Latin
                    America looking particularly attractive relative to other
                    regions. Exposure to Eastern European debt was reduced at
   the start of the second quarter to reap profits from a strong performance
   earlier in the year.
 
   The Fund also realized gains in the non-U.S. investment grade sector. A key
   move here saw a shift out of Canadian government bonds, which had rallied
   relative to U.S. Treasuries as the Canadian government took steps to reduce
   budget deficits at both the federal and provincial levels.

SALOMON  BROTHERS  INVESTMENT  SERIES

- --------------------------------------------------------------------------------


 
   Another strategy contributing to the Fund's strong performance was
   underweighting investment grade bonds during the first half of 1996. These
   issues were subject to troublesome volatility through the period, as interest
   rates spiked up periodically on the release of strong monthly employment
   reports. Our highly-defensive 2% position in investment grade debt as of June
   30, 1996 indicates our continued wariness toward this sector of the bond
   market.
 
   One of the strongest arguments for a global bond fund is the ability to
   rotate in or out of fixed-income sectors as opportunities arise to enhance
   performance or avoid risk. As we move into the second half of 1996, we intend
   to keep searching the globe for attractive fixed income investments.

Allan R. White

                   MEET YOUR FUND MANAGER
                   Allan R. White, Managing Director and Portfolio Manager at
                   Salomon Brothers Asset Management Inc, has 15 years of
                   experience managing equity, convertible and fixed income
                   securities. Mr. White is primarily responsible for day-to-day
                   Fund management.

                   INVESTMENT OBJECTIVE
                   Long-term growth of capital. Current income is a secondary
                   objective.
 
   INVESTMENT STRATEGY
   The Fund invests primarily in common stocks listed on the New York Stock
   Exchange and other U.S. exchanges. The portfolio manager maintains a
   long-term investment focus. While we believe that economic forecasting has a
   role to play in helping us identify promising stocks, we devote most of our
   resources to identifying attractive companies rather than trying to predict
   market trends. Our stock selection process continues to be aimed at finding
   companies with strong management, accelerating operating trends, healthy
   balance sheets and strong competitive positions.
 
   MARKET REVIEW
   Over the last eighteen months the equity markets have benefited from a
   confluence of positive factors. Inflation has been benign, economic growth
   has been moderate and earnings growth has been very strong. The Investors
   Fund's strong relative performance in the first half of 1996 came from
   security selection, and to a lesser degree, favorable sector weightings.
   Large positions aiding performance included Sears, Roebuck, Praxair, Tyco
   International and Stop & Shop Companies.
 
   During the second half of the year, we believe that markets may be
   characterized by more volatility than we have seen the last eighteen months.
   Steady earnings growth is highly valued in uncertain market environments. As
   a result, we have built up our positions in the medical sector. Operating
                    trends for companies such as SmithKline Beecham,
                    Rhone-Poulenc Rorer and Columbia/HCA Healthcare are very
                    favorable. We continue to search for undervalued stocks and
                    have begun selectively to buy high quality technology
[GRAPH]             stocks, after their recent declines.

Richard Dahlberg
                   MEET YOUR FUND MANAGER
                   Richard E. Dahlberg, Managing Director and Portfolio Manager
                   at Salomon Brothers Asset Management Inc, has 36 years of
                   experience managing equity securities. Mr. Dahlberg is
                   primarily responsible for day-to-day Fund management.

 
                   INVESTMENT OBJECTIVE
                   The Fund seeks to obtain above average income compared to a
                   portfolio that invests only in stocks. The Fund's secondary
                   objective is to seek growth of capital and income. The Fund
                   seeks to achieve its objectives by investing in a broad
   variety of securities including equities, fixed income securities and short
   term obligations.
 
 
   INVESTMENT STRATEGY
   The Fund seeks to produce substantial current income and provide for long
   term growth of capital and income. The Fund invests primarily in large
   capitalization stocks that are paying dividends greater than the Standard &
   Poor's 500 Index average. Fixed income assets are allocated among securities
   believed capable of achieving equity like returns, such as high yield bonds
   and convertible securities as well as in investment grade bonds.
 
   MARKET REVIEW
   A relative newcomer to the Salomon Brothers Investment Series, the Total
   Return Fund has generated impressive relative returns since inception in
   September 1995. This performance was aided during the first half of 1996 by
                    emphasis on financial services and energy stocks and by
                    avoiding areas where stocks appear to be over-priced, such
                    as technology stocks. The emphasis on high yield bonds as
                    opposed to government bonds also contributed to both income
                    and performance.
 
                    After a long bull market, many U.S. corporations are now at
                    lofty valuations. We believe that long-term investment value
                    lies with companies that serve developing countries, where
                    growth rates far exceed those of the developed nations. Two
                    beneficiaries of this trend, Eastman Kodak and Citicorp,
                    generate an ever growing portion of their revenue from
                    non-U.S. markets.
 
                    The energy sector is also benefiting from the rising
                    consumption of developing countries and showing significant
                    potential after 15 years of lackluster relative performance.
                    During the first half of 1996, the Fund held a number of
                    energy issues, including Dresser Industries, Suncor and
                    Williams Cos. We feel that prices for energy stocks do not
                    fully reflect their long-term potential and we will continue
                    to look for opportunities in this area.
 [GRAPH]
                    The Fund also benefited from investments in a number of real
                    estate investment trusts (REIT), which currently offer high
   current yields, plus the potential for future dividend growth. Like energy
   stocks, we believe REITs offer good value today and could be emerging from
   years of under-performance. With electric utilities currently less attractive
   due to uncertainty in the regulatory environment, we look to REITs to provide
   a healthy portion of

   the monthly income component investors expect from the Salomon Brothers Total
   Return Fund.
 
   Our wariness toward the technology sector significantly helped our
   performance versus the stock market during the first half of 1996. A year
   ago, we anticipated price declines of up to 50% in some technology stocks and
   many issues have already exceeded this plunge in value. Consequently, there
   may be an opportunity to buy technology issues at bargain prices over the
   next 6-12 months. On the bond side of the portfolio, the Fund's emphasis on
   higher yielding corporate debt greatly enhanced performance.
 
  
   As is generally the case after periods of speculation in the market, we
   believe that investors will be attracted to large, financially-sound
   companies for their stability, yield and dividend growth potential. We will
   continue to focus on the stocks of well-run, well-capitalized companies as
   the prices become attractive.

   SALOMON BROTHERS ASIA GROWTH FUND
 
[PHOTO]
Giampaolo G. Guarnieri

                   MEET YOUR FUND MANAGER
                   Giampaolo G. Guarnieri, Director, Portfolio Manager and
                   Co-Chief of Salomon Brothers Asset Management Asia Pacific
                   Limited (SBAM AP), has 10 years of experience managing equity
                   securities. SBAM AP is the Hong Kong affiliate of Salomon
                   Brothers Asset Management Inc and serves as a sub-advisor to
                   the Fund. Mr. Guarnieri is primarily responsible for day-to-
                   day Fund management.
 
   INVESTMENT OBJECTIVE
   Long-term capital appreciation.
 
   INVESTMENT STRATEGY
   The Fund invests primarily in the equity and equity-related securities of
   companies located in developing nations of the Pacific Rim, with the
   exception of Japan. Areas considered for investment include, but are not
   limited to, China, Hong Kong, Indonesia, Korea, Malaysia, the Philippines,
   Singapore and Thailand. In seeking to capture high long-term returns with
   reduced volatility, Fund managers will allocate assets among countries and
                    industries believed most likely to benefit from regional
                    economic trends.
 
                    MARKET REVIEW
                    The goal of our Asia Pacific equity investment process is to
                    capture the region's high potential returns while actively
                    managing volatility by spreading risk over a number of
                    countries, industries and companies. Our approach to Asian
                    markets is as follows. First, we evaluate the region's
                    economy, sectors and securities. We then apply proprietary
                    risk management and asset allocation tools in seeking to
                    reduce overall portfolio volatility.
 
                    Several Pacific rim countries currently offer excellent
                    investment opportunities for long-term equity investors. The
                    overall pace of Gross Domestic Product (GDP) growth in Asia
                    (excluding Japan) continues to be strong and, we believe,
                    the average growth rate could exceed 7% for the next few
                    years. Earnings-per-share growth for Pacific rim stocks has
                    also been quite impressive and we believe this figure could
                    average 15% going forward. Despite these growth rates,
                    market valuations remain attractive, especially in Hong
                    Kong, where equities may trade at 12 times estimated 1996
                    earnings.
    [GRAPH]


                    Long-term factors driving future growth include
                    infrastructure improvements, which are leading to greater
                    cross-border trade, intra-regional investment flows and
                    growing consumerism, as economic growth starts to penetrate
                    formerly dormant areas of Asia. As more and more Pacific rim
                    companies come to the equity markets for their
                    capital-raising needs, investors are being offered a rapidly
                    expanding menu of investment opportunities.

   SALOMON BROTHERS U.S. GOVERNMENT INCOME FUND

[PHOTO]
Roger Lavan
                   MEET YOUR FUND MANAGERS
                   Steven Guterman, Managing Director and Portfolio Manager at
                   Salomon Brothers Asset Management Inc, has 16 years of
                   experience managing fixed income securities. Mr. Guterman is
                   primarily responsible for day-to-day Fund management.
 
                   Roger Lavan, Director and Portfolio Manager at Salomon
                   Brothers Asset Management Inc, has 9 years of experience
                   managing fixed income securities. Mr. Lavan assists in the
                  day-to-day Fund management.

   INVESTMENT OBJECTIVE
   To obtain a high level of current income.
 
   INVESTMENT STRATEGY
   Under normal market conditions the Fund invests 100% of its net assets in
   debt obligations and mortgage-backed securities issued by or guaranteed by
   the U.S. government, its agencies or instrumentalities. The Fund expects to
   maintain an average portfolio duration of three to five years.
 
   MARKET REVIEW
   During the six months ended June 30, 1996, the Fund continued to overweight
   mortgage-backed securities while underweighting U.S. Treasuries. In the near
   term, we believe mortgage-backed securities will continue to be attractive,
   as higher interest rates have reduced the incentive for homeowners to
   refinance their mortgages. Barring a significant market rally, we believe
   mortgage-backed securities are likely to perform well in the coming months
   and will be favored over Treasuries in the Fund.
 
   In the first half, economic data -- such as home sales, the unemployment
   rate, and average hourly earnings -- pointed towards relatively strong
   economic growth with the possibility of higher levels of inflation. To
   protect the Fund from higher interest rates, a move to a more defensive
                    stance was taken early in the second quarter. The Fund's
                    duration -- which measures the sensitivity of the Fund's
                    holdings to interest rate changes -- was shortened to
                    approximately 2.5 years, down from 4.0 years at the end of
                    1995.
 
                    In an effort to offset the lower average duration from
                    significantly reducing the Fund's yield, U.S. Treasury
                    securities were swapped into higher-yielding agency mortgage
                    pass-through securities. This move was also designed to
                    protect the Fund should the Federal Reserve raise interest
[GRAPH]             rates during the second half of 1996. Looking forward, we
                    expect economic growth to slow over the coming months,
                    permitting the Fund to extend into longer maturity issues
                    in pursuit of higher yields.

   SALOMON BROTHERS NATIONAL INTERMEDIATE MUNICIPAL FUND

[PHOTO]
Marybeth Whyte
                   MEET YOUR FUND MANAGER
                   Marybeth Whyte, Director and Portfolio Manager at Salomon
                   Brothers Asset Management Inc, has 13 years of experience
                   managing municipal securities. Ms. Whyte is primarily
                   responsible for day-to-day Fund management.
 
                   INVESTMENT OBJECTIVE
                   To achieve a high level of current income exempt from regular
                   federal income taxes. All or a portion of the Fund's
                   dividends paid in respect to its shares may be subject to the
                   federal alternative minimum tax.

   INVESTMENT STRATEGY
   Under normal circumstances, at least 80% of the Fund's net assets will be
   invested in municipal obligations, the interest on which is exempt from
   regular federal income tax.
 
   MARKET REVIEW
   Our approach to the municipal bond market focuses on benefiting from
   long-term fundamentals rather than short-term market trends. Having witnessed
   relatively high levels of volatility during the past six months, we feel it
   is more important than ever to adhere to this approach, which emphasizes
   rigorous credit analysis and careful sector selection.
 
   In the first six months of 1996, robust demand from individual investors and
   insurance companies helped municipal bonds outperform taxable fixed-income
   securities. Even though stronger-than-expected economic data in April and May
   caused bond prices to falter, losses in the municipal sector were tempered
                    due to strong supply/demand technicals. Individual investors
                    were drawn to municipal bonds as long-term yields exceeded
                    6.0%, the stock market became more volatile and fear of a
                    flat tax lessened. On the institutional side, demand from
                    property and casualty insurance companies continued due to
                    their sustained profitability. Municipals gathered
                    additional strength as much of the estimated $25 billion
                    from June maturities, redemptions and coupon payments was
                    reinvested in the municipal market in a period of light new
                    issue supply.
  [GRAPH] 
                    In coming months, anticipated cash from municipal coupon
                    payments, maturities and redemptions, combined with an
                    expected light new issue calendar should enable municipals
                    to continue their favorable technical position.

   SALOMON BROTHERS NEW YORK MUNICIPAL BOND FUND

   MEET YOUR FUND MANAGER
   Marybeth Whyte, Director and Portfolio Manager at Salomon Brothers Asset
   Management Inc, has 13 years of experience managing municipal securities. Ms.
   Whyte is primarily responsible for day-to-day Fund management.
 
   INVESTMENT OBJECTIVE
   To achieve a high level of current income exempt from regular federal income
   taxes and New York State and New York City personal income taxes, consistent
   with the preservation of capital.
 
   INVESTMENT STRATEGY
   Under normal market conditions, the Fund will invest at least 65% of its net
   assets in obligations the interest on which is exempt from personal income
   taxes of New York State and New York City, and at least 80% of its net assets
   in obligations the interest on which is exempt from regular federal income
   taxes. All or a portion of the Fund's dividends paid in respect to its shares
   may be subject to the federal alternative minimum tax.
 
   MARKET REVIEW
   The New York municipal market performed in line with national municipal bonds
   during the first half of 1996. Municipals, including New York tax-exempts,
   outpaced their taxable counterparts during this time period despite a high
   level of volatility. This better relative performance was attributable to a
   favorable supply/demand imbalance in the municipal market. Furthermore, this
   imbalance was magnified in the New York arena, which witnessed a significant
   decline in new issue supply due to the inability of the state's legislature
   to pass a timely budget.
 
   For the first six months of the year, individual investors as well as
   property and casualty insurance companies were dominant buyers in the
   municipal market. Individual investors were enticed by the attractive nominal
   yields afforded in the marketplace. In addition, the stock market's
                    heightened volatility caused some individuals to increase
                    their asset allocation toward municipals. Property and
                    casualty insurance companies remain a market stalwart due to
                    their continued profitability. The New York municipal market
                    benefited from both scenarios.
 
                    Now that the New York State budget is in place we anticipate
                    an increase in new issues for the Empire State. Nonetheless,
                    we remain optimistic that the positive technicals in the
[GRAPH]             municipal market will continue in the coming months.

     `D' Return does not reflect the deduction of any sales charge.
 
 `D' `D' Lipper Analytical Services, an industry recognized analysis company,
         calculates rankings based on total return performance of funds
         within each category. Lipper rankings change monthly and do not
         reflect the effects of sales charges. Accordingly, the results in
         this table for the Class A, Class B and Class C shares of each Fund
         do not reflect the effect of the sales charges applicable to each
         Class, which are described in the footnotes below. Lipper
         performance results represent changes in net asset value, adjusted
         to reflect reinvestment of dividends and capital gains.Class A
         shares are subject to an annual 12b-1 service fee of .25% of the
         value of the average daily net assets. Class B and Class C shares
         are subject to an annual 12b-1 service and distribution fee of
         1.00%. Class O shares are not subject to an annual 12b-1 fee.
 
     * Maximum sales charge for Class A shares is 4.75% of the public offering
       price. Class A shares bear ongoing annual 12b-1 service fee of .25%.
 
    ** Maximum contingent deferred sales charge for Class B and Class C shares
       are 5% and 1%, respectively, and is reduced to 0% after 6 years and 1
       year, respectively. Class B and Class C shares are subject to annual
       12b-1 service and distribution fees in an aggregate amount of 1.00%.
 
    *** Each Fund offers Class O shares to existing shareholders of Class O
        shares in the Investment Series. Class O shares do not have initial or
        contingent deferred sales charges or ongoing distribution and service
        fees.
 
     [c] Commencement of investment operations.
 
   GENERAL PERFORMANCE AND RANKING NOTES
 
   Average annual total returns are based on changes in net asset value and
   assume the reinvestment of all dividends and/or capital gains distributions
   in additional shares with and without the effect of the maximum sales charge
   (Class A) and the contingent deferred sales charge (Class B and C). The
   average annual return for a period less than a year has not been annualized.
   Past performance does not guarantee future results. Investment return and
   principal value fluctuate so that an investor's shares, when redeemed, may be
   worth more or less than their original cost. Returns reflect a voluntary
   expense cap, (except for Investors Fund) imposed by SBAM to limit total Fund
   operating expenses. Absent this expense cap, Fund expenses would be higher
   and returns lower. As a result, the expense caps had a material effect on the
   ranking of each Class of each Fund in its relevant Lipper category.

SALOMON BROTHERS INVESTMENT SERIES

Notes  to  Financial  Statements (unaudited)
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
The Salomon Brothers Investment Series (the 'Investment Series') consists of
certain portfolios of the Salomon Brothers Series Funds Inc (the 'Series
Funds'), as indicated below, and the Salomon Brothers Investors Fund Inc (the
'Investors Fund'). The Series Funds were incorporated in Maryland on April 17,
1990 as an open-end management investment company, and currently operate 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 'Institutional Money Market 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'). Separate financial
statements are prepared for the New York Municipal Money Fund and the
Institutional Money Market Fund which are not part of the Investment Series. All
of the other portfolios of the Series Funds are included in the Investment
Series, which also includes the Investors Fund, a diversified open-end
management investment company incorporated in Maryland on April 2, 1958. The
Investment Series operates under a multiple class pricing structure, with each
portfolio of the Investment Series (individually, a 'Fund') offering Class A,
Class B, Class C, and Class O shares, each with their own expense structure.
Each Fund has a specific investment objective: the Cash Management Fund's
objective is to seek as high a level of current income as is consistent with
liquidity and the stability of principal; the New York Municipal Bond Fund's
objective is to achieve a high level of current income which is exempt from
regular federal income taxes and New York State and New York City personal
income taxes, consistent with the preservation of capital; the National
Intermediate Municipal Fund's objective is to seek a high level of current
income which is exempt from regular federal income taxes; the U.S. Government
Income Fund's objective is to seek a high level of current income; the High
Yield Bond Fund's primary objective is to maximize current income; the Strategic
Bond Fund's primary objective is to seek a high level of current income; the
Total Return Fund's primary objective is to obtain above-average income
(compared to a portfolio entirely invested in equity securities); the Asia
Growth Fund's and Investors Fund's objective is to seek long-term growth of
capital.
 
Certain costs incurred in connection with each Fund's organization, which were
payable to Salomon Brothers Asset Management Inc ('SBAM') have been deferred and
are being amortized by the Funds over a 60 month period from the date each Fund

</TABLE>
 
The following is a summary of significant accounting policies followed by the
Investment 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, other than the Cash Management 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.
 
          Portfolio securities for the Cash Management Fund 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.
 
                                                                         PAGE 55

Notes  to  Financial  Statements (unaudited)
 
          Foreign securities quoted in a foreign currency are translated into
     U.S. dollars using exchange rates at 2:30 p.m. Eastern time or at such
     other rates as 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.
 
          (B) FUTURES CONTRACTS. The New York Municipal Bond Fund, National
     Intermediate Municipal Fund, High Yield Bond Fund, Strategic Bond Fund,
     Total Return Fund, Asia Growth Fund and Investors Fund may enter into
     futures contracts, which involves paying or receiving variation margin,
     which will be recorded as unrealized gain or loss until the contract is
     closed. When the contract is closed, a realized gain or loss will be
     recognized. Outstanding contracts involve elements of market risk in excess
     of amounts reported in the financial statements.
 
          (C) 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.
 
          (D) MORTGAGE ROLLS. The U.S. Government Income Fund, Strategic Bond
     Fund and Total Return Fund may enter into mortgage 'dollar rolls' in which
     a Fund sells mortgage-backed securities for delivery in the current month
     and simultaneously contracts to repurchase substantially similar (same
     type, coupon and maturity) securities on a specified future date. The Fund
     is compensated by a fee paid by the counterparty. Dollar rolls are
     accounted for as financing arrangements; the fee is accrued into interest
     income ratably over the term of the dollar roll and any gain or loss on the
     roll is deferred until disposition of the rolled security. The average
     daily balance of dollar rolls outstanding during the six months ended June
     30, 1996 was approximately $1,023,000, $618,000, $109,000 for the U.S.
     Government Income Fund, Strategic Bond Fund and Total Return Fund,
     respectively.
 
          (E) 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 always 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.
 
          (F) FOREIGN CURRENCY TRANSLATION. The accounting records of each Fund
     are maintained in U.S. dollars. Investment securities and other assets and
     liabilities of the High Yield Bond Fund, Strategic Bond Fund, Total Return
     Fund, Asia Growth Fund and Investors Fund 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.
 
          (G) FORWARD FOREIGN CURRENCY CONTRACTS. The High Yield Bond Fund,
     Strategic Bond Fund, Total Return Fund, Asia Growth Fund and Investors 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.
 
          (H) LOAN PARTICIPATIONS. The High Yield Bond Fund, Strategic Bond Fund
     and Total Return Fund may invest in fixed and floating rate loans arranged
     through private negotiations between a foreign sovereign entity and one or
     more financial institutions ('lender'). The market values of the High Yield
     Bond Fund and the Strategic Bond Fund's loan participations at June 30,
     1996 were $1,083,749 and $361,250, respectively.
 
          In connection with purchasing participations, the Fund generally will
     have no right to enforce compliance by the borrower, and the Fund may not
     benefit directly from any collateral supporting the loan in which it has
     purchased the participation. As a result, the Fund will assume the credit
     risk of both the borrower and the
 
                                                                         PAGE 57

     lender that is selling the participation. In the event of the insolvency of
     the lender selling the participation, the Fund may be treated as a general
     creditor of the lender and may not benefit from any set-off between the
     lender and the borrower.
 
          (I) FEDERAL INCOME TAXES. Each Fund intends 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.
 
          (J) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends from net
     investment income on the shares of each of the Funds (except the Asia
     Growth Fund and Investors Fund) are declared each business day to
     shareholders of record that day, and are paid on the last business day of
     the month. Dividends from net investment income for the Asia Growth Fund
     will be declared on an annual basis. Dividends from net investment income
     for the Investors Fund are declared on a quarterly basis. 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 generally accepted accounting
     principles due primarily to differences in the treatment of foreign
     currency gains/losses, deferral of wash sales, and post-October losses
     incurred by each 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 distributions in excess of net investment income and
     distributions in excess of net realized capital gains.
 
          (K) CLASS ACCOUNTING. Investment income, common expenses and gain
     (loss) on investments are allocated to the various classes of a Fund on the
     basis of daily net assets of each class. Distribution and shareholder
     servicing fees relating to a specific class are charged directly to that
     class. No class has preferential dividend rights; differences in per share
     dividend rates are generally due to differences in separate class expenses.
 
          (L) EXPENSES. Direct expenses are charged to the Fund that incurred
     them, and general expenses of the Investment Series are allocated to the
     Funds based on each Fund's relative net assets.
 
          (M) OTHER. Investment transactions are recorded as of the trade date.
     Dividend income is recorded on the ex-dividend date. 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. Net investment income (other than distribution fees)
     and unrealized and realized gains or losses are allocated daily to

     each class of shares based upon the relative proportion of each class's net
     assets to the Fund's total net assets.
 
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 each Fund. SBAM furnishes the Investment Series with office
space and certain services and facilities required for conducting the business
of the Investment Series and pays the compensation of its officers. The
management fee for these services for each Fund (except the Investors Fund) is
payable monthly and is based on the following annual percentages of each Funds'
average daily net assets: .20% for the Cash Management Fund, .50% for the New
York Municipal Bond Fund and the National Intermediate Municipal Fund, .60% for
the U.S. Government Income Fund, .75% for the High Yield Bond Fund and Strategic
Bond Fund, .55% for the Total Return Fund and .80% for the Asia Growth Fund.
SBAM Limited provides certain advisory services to SBAM for the benefit of the
Strategic Bond Fund. SBAM Limited is compensated by SBAM at no additional
expense to the Strategic Bond Fund. SBAM has retained SBAM AP 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. SBAM Limited 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.
 
The Investors Fund pays SBAM a base fee subject to an increase or decrease
depending on the extent, if any, to which the investment performance of the
Investors Fund exceeds or is exceeded by the investment record of the Standard &
Poor's 500 Index of Composite Stocks ('S&P 500 Index'). The base fee is paid
quarterly based on the following annual rates:

Next $250 million...................................................................      .350%
Over $1 billion.....................................................................      .300%
</TABLE>
 
The performance adjustment is paid quarterly based on a rolling one year period.
A performance adjustment will only be made after the investment performance of
the Investors Fund exceeds or is exceeded by the investment record of the S&P
500 Index by at least one percentage point. For each percentage point by which
the investment performance of the Investors Fund exceeds or is exceeded by the
investment record of the S&P 500 Index, the base fee will be adjusted upward or
downward by .01% (annualized). The maximum annual adjustment is .10% which would
occur if the Investors Fund's performance exceeds or is exceeded by the S&P 500
Index by ten or
 
                                                                         PAGE 59

more percentage points. For the rolling years ended March 31, 1996 and June 30,
1996, the Investors Fund's performance exceeded the investment record of the S&P
Index by approximately two and three percent, respectively. As a result, base
management fees were increased by $19,564 at March 31, 1996, and $34,793 at June
30, 1996.
 
For the period ended June 30, 1996, SBAM waived management fees of $14,070,
$9,407, $27,483, $31,879, $78,869, $57,889, $66,106 and $6,014 for the Cash
Management 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, respectively, and voluntarily absorbed
expenses of $724, $10,369, $35,468, $35,313, $7,293, $39,794 and $4,890 for the
Cash Management Fund, New York Municipal Bond Fund, National Intermediate
Municipal Fund, U.S. Government Income Fund, Strategic Bond Fund, Total Return
Fund and Asia Growth Fund, respectively.
 
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 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
period ending June 30, 1996.
 
Investors Bank & Trust Company serves as custodian and administrator for each
Fund, which includes performing certain administrative services in connection
with the operation of each Fund. During the period ended June 30, 1996, credits
earned on outstanding cash balances were used to reduce custodian fees by $5,
$1,134, $1,148, $12, $391, $6, $218 and $202 for the Cash Management Fund, New
York Municipal Bond Fund, National Intermediate Municipal Fund, U.S. Government
Income Fund, High Yield Bond Fund, Total Return Fund, Asia Growth Fund and
Investors Fund, respectively.
 
Each Fund has an agreement with Salomon Brothers Inc ('Salomon Brothers'), an
affiliate of the Investment Adviser, to distribute its shares pursuant to a
multiple pricing system. Each class (except for Class O) of each Fund (except
for the Cash Management Fund) is authorized pursuant to a services and
distribution plan applicable to that class of shares (the 'Class A Plan,' the
'Class B Plan,' and the 'Class C Plan,' collectively, the 'Plans') adopted
pursuant to Rule 12b-1 under the Investment Company Act of 1940, as amended (the
'1940 Act'), to pay Salomon Brothers an annual service fee with respect to Class
A, Class B, and Class C shares of the applicable Funds at the rate of .25% of
the value of the average daily net assets of the respective class. Salomon
Brothers is also paid an annual distribution fee with respect to Class B and
Class C shares of each Fund (except for the Cash Management Fund) at the rate of
 .75% of the

value of the average daily net assets of the respective class. Class O shares
are not subject to a services and distribution plan fee.
 
Brokerage commissions of $600 and $29,364 were paid by the Total Return Fund and
Investors Fund, respectively, to Salomon Brothers, the Funds' distributor and an
indirect wholly-owned subsidiary of Salomon Inc, for transactions executed on
behalf of the Funds for the period ended June 30, 1996.
 
Salomon Brothers received $7,088 as its portion of the front-end sales charge on
sales of Class A shares of the Funds during the period ended June 30, 1996. In
addition, contingent deferred sales charges of $59,533 were paid to Salomon
Brothers in connection with redemptions of certain Class B and Class C shares of
the Funds during the period ended June 30, 1996.

During the period ended  June 30, 1996, net  realized gain from forward  foreign
currency  contracts for  the Strategic  Bond Fund  amounted to  $27,577, and net
realized losses from forward currency contracts amounted to $4,262 for the  Asia
Growth  Fund. Net realized  losses on mortgage dollar  rolls amounted to $29,766
and $21,828  for  the U.S.  Government  Income  Fund and  Strategic  Bond  Fund,
respectively.
 
5. PORTFOLIO INVESTMENT RISKS
 
CREDIT AND MARKET RISK. Funds that invest in high yield and emerging market
instruments are subject to certain credit and market risks. The yields of high
yield and emerging market 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.
 
The Cash Management 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. The
New York Municipal Bond Fund pursues its investment objectives by investing at
least 80% of its net assets in obligations that are exempt from regular federal
income taxes and at least 65% of its net assets in obligations that are exempt
from personal income taxes of the State and City of New York. Because the New
York Municipal Bond Fund invests primarily in obligations of the State and City
of New York, it is more susceptible to factors adversely affecting issuers of
such obligations than a fund that is more diversified.
 
FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK. Certain Funds 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 Statement 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.
 
Funds that enter into mortgage dollar rolls are subject to the risk that the
market value of the securities the Fund is obligated to repurchase under the
agreement may decline below the repurchase price. In the event the buyer of
securities under a mortgage dollar roll files for bankruptcy or becomes
insolvent, the Fund's use of proceeds of the dollar
 
                                                                         PAGE 65

roll may be restricted pending a determination by the other party, or its
trustee or receiver, whether to enforce the Fund's obligation to repurchase the
securities.
 
Consistent with their objective to seek high current income, the High Yield Bond
Fund and the Strategic 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 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.

 * Total return is calculated assuming a $1,000 investment on the first day of
   each period reported, reinvestment of all dividends at the net asset value on
   the payable date, and a sale at net asset value on the last day of each
   period reported. Initial sales charge or contingent deferred sales charge is
   not reflected in the calculation of total return. Total return calculated for
   a period of less than one year is not annualized.
 ** Annualized.

 * Total  return is calculated assuming a $1,000  investment on the first day of
   each period reported, reinvestment of all dividends at the net asset value on
   the payable date,  and a  sale at net  asset value  on the last  day of  each
   period  reported. Initial sales charge or contingent deferred sales charge is
   not reflected in the calculation of total return. Total return calculated for
   a period of less than one year is not annualized.
 ** Annualized.

31, 1995.
 SS Per share  information  calculated  using  the  average  shares  outstanding
    method, which more accurately represent amounts.
 * Total  return is calculated assuming a $1,000  investment on the first day of
   each period reported, reinvestment of all dividends at the net asset value on
   the payable date,  and a  sale at net  asset value  on the last  day of  each
   period  reported. Initial sales charge or contingent deferred sales charge is
   not reflected in the calculation of total return. Total return calculated for
   a period of less than one year is not annualized.
 ** Annualized.

 SS Per share  information  calculated  using  the  average  shares  outstanding
    method, which more accurately represent amounts.
 *  Total return is calculated assuming a $1,000  investment on the first day of
    each period reported, reinvestment of all dividends at the net  asset  value
    on the payable date, and a sale at net asset value on the last  day of  each
    period reported. Initial sales charge or contingent deferred sales charge is
    not reflected in the calculation of total return.  Total  return  calculated
    for a period of less than one year is not annualized.
 ** Annualized.

 * Total return is calculated assuming a $1,000 investment on the first day of
   each period reported, reinvestment of all dividends at the net asset value on
   the ex-dividend date, and a sale at net asset value on the last day of each
   period reported. Initial sales charge or contingent deferred sales charge is
   not reflected in the calculation of total return. Total return calculated for
   a period of less than one year is not annualized.
** Annualized.

SEMI-ANNUAL REPORT

                 Salomon Brothers
                 New York Municipal Money Market Fund
August 19, 1996
 
To Our Shareholders:
 
WE ARE PLEASED to provide this semi-annual report of the Salomon Brothers New
York Municipal Money Market Fund which includes market commentary and a
statement of the Fund's current investments, for the period ended June 30, 1996.
 
THE FUND'S ANNUALIZED YIELD for the seven days ended June 30, 1996 was 3.25%.
For the same period, shareholders reinvesting their dividends earned a
compounded effective annualized yield of 3.30%. During the six month period
ended June 30, 1996, the Fund returned 1.63% which exceeded the 1.42% average
return of New York municipal money market funds as measured by Lipper Analytical
Services*. This investment return ranked the Salomon Brothers New York Municipal
Money Market Fund #1 of 40 funds for the period.
 
ON JULY 17, 1996, the Fund's Board of Directors approved the implementation by
the Fund of the Multiple Class Pricing System currently in place for the other
funds which are part of the Salomon Brothers Investment Series family of funds.
 
UNDER THE Multiple Class Pricing System, the Funds in the Investment Series
offer different classes of shares. Except for the money market funds, like the
Fund, each class has different distribution and sales charge options. You will
continue to have the ability to purchase additional shares of the New York
Municipal Money Market Fund without paying any sales charges or distribution
fees and shares you currently hold also will not be subject to any sales charge
or distribution fees. In addition, you will be able to exchange your shares of
the Fund for shares of the other funds in the Investment Series, without
imposition of any sales charges, distribution or service fees.
 
FOLLOWING IMPLEMENTATION, you will no longer have the ability to exchange your
shares of the Fund for shares of Salomon Brothers Opportunity Fund Inc, but it
is anticipated that the Salomon Brothers Capital Fund Inc will be joining the
Investment Series and should that occur your ability to exchange for shares of
the Capital Fund will continue. The Fund will no longer have its own prospectus
and statement of additional information, but will be combined with the other
Funds in the Investment Series.
 
Economic Review
 
ECONOMIC GROWTH ACCELERATED during the first half of 1996 and
stronger-than-expected gains in employment and hourly wages lent support to the
possibility of higher inflation. We believe that this acceleration however, will
prove to be self-limiting: Gross Domestic Product growth will slow toward trend
level during the next six to nine months.
<PAGE>
<PAGE>
RECENTLY, THERE HAS been evidence that the pace of economic expansion has cooled
from its heated first-half pace. Thus, the Federal Reserve has been spared the
need for a much-anticipated summer tightening of credit. After some slowing in
consumer and factory activity in June and July, policymakers again have assumed
a wait-and-see posture. However, while market rates have retreated from their
earlier peaks, the risk of renewed interest rate pressures remains high. Hiring
demands are well above trend, and forward-looking labor market indicators signal
continued strength. Upbeat consumer sentiment echoes these solid labor gains,
belying any notion that consumers will continue to pull back. If consumers
return, a backdrop of lean inventories and limited slack could spark renewed
vigor in manufacturing and revived inflation concerns. Thus, the debate over
potential Fed tightening is likely to linger for some time.
 
ALL OF US at Salomon Brothers Asset Management Inc appreciate the confidence you
have demonstrated in the past and hope to continue to justify such confidence in
the future. Please call us with any questions at 1-800-SALOMON (1-800-725-6666).

                                                   Cordially,

                                                   /s/ MICHAEL S. HYLAND
 
                                                   MICHAEL S. HYLAND

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 "Fund"), Salomon Brothers Institutional Money
Market Fund (the "Institutional Money Market 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's objective is to seek as high a level of current income exempt
from federal, New York State and New York City personal income taxes as is
consistent with liquidity and the stability of principal. The Cash Management
Fund, Institutional Money Market 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.

SALOMON    BROTHERS     NEW     YORK     MUNICIPAL     MONEY     MARKET     FUND
 
       (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 month. Distributions of net realized gains to shareholders, if any, are
   declared annually and recorded on the ex-dividend date. Dividends and
   distributions are determined in accordance with income tax regulations, which
   may differ from GAAP.
 
       (D) EXPENSES. Direct expenses are charged to the Fund, and general
   expenses of the Company are allocated to the Fund based on relative average
   net assets for the period the expense was incurred.
 
       (E) OTHER. Investment transactions are recorded as of the trade date.
   Interest income, including the accretion of discounts or the amortization of
   premiums, is recognized when earned. Gains or losses on sales of 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.
 
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.
 
Investors Bank & Trust Company serves as custodian and administrator 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 $2,134 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.
 
                                                                         PAGE 11

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.
 
Net assets consist of:

                                                                                                ------------
</TABLE>
 
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. The Fund pursues its investment
objective by investing, under normal market conditions, at least 65% of its
total assets in obligations that are exempt from Federal income tax and from
personal income taxes of the State of New York and its cities. Because the Fund
invests primarily in obligations of the State of New York and its cities, it is
more susceptible to factors adversely affecting issuers of such obligations than
a fund that is more diversified.
 
At December 31, 1995, the Fund had net capital loss carry-forwards available to
offset future capital gains as follows:

</TABLE>
 
5.  Subsequent Event
 
On July 17, 1996, the Board of Directors of the Fund approved the implementation
of a multiple class pricing system. In connection with such implementation, the
Fund will designate all outstanding shares of capital stock as Class O and will
create three new classes designated Class A, Class B and Class C shares.

THE SALOMON BROTHERS Institutional Money Market Fund's annualized yield for the
seven days ended June 30, 1996 was 5.21%. For the same period, shareholders
reinvesting their dividends earned compounded effective annualized yields for
the Fund of 5.35%.
 
EFFECTIVE APRIL 29, 1996, the Fund was restructured as a general purpose money
market fund to be marketed primarily to institutional investors. This
restructuring was approved by shareholders at a special meeting held on March
26, 1996.
 
Economic Review
 
ECONOMIC GROWTH accelerated during the first half of 1996 and
stronger-than-expected gains in employment and hourly wages lent support to the
possibility of higher inflation. We believe that this acceleration however, will
prove to be self-limiting: Gross Domestic Product growth will slow toward trend
level during the next six to nine months.
 
RECENTLY, THERE HAS been evidence that the pace of economic expansion has cooled
from its heated first-half pace. Thus, the Federal Reserve has been spared the
need for a much-anticipated summer tightening of credit. After some slowing in
consumer and factory activity in June and July, policymakers again have assumed
a wait-and-see posture. However, while market rates have retreated from their
earlier peaks, the risk of renewed interest rate pressures remains high. Hiring
demands are well above trend, and forward-looking labor market indicators signal
continued strength. Upbeat consumer sentiment echoes these solid labor gains,
belying any notion that consumers will continue to pull back. If consumers
return, a backdrop of lean inventories and limited slack could spark renewed
vigor in manufacturing and revived inflation concern. Thus, the debate over
potential Fed tightening is likely to linger for some time.

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

SALOMON        BROTHERS        INSTITUTIONAL       MONEY       MARKET       FUND
 
   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 month. Distributions of net realized gains to shareholders, if any, are
   declared annually and recorded on the ex-dividend date. Dividends and
   distributions are determined in accordance with income tax regulations, which
   may differ from GAAP.
 
       (D) EXPENSES. Direct expenses are charged to the Fund, and general
   expenses of the Company are allocated to the Fund based on relative average
   net assets for the period the expense was incurred.
 
       (E) OTHER. Investment transactions are recorded as of the trade date.
   Interest income, including the accretion of discounts or the amortization of
   premiums, is recognized when earned. Gains or losses on sales of 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.

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.
