recognition from Lipper Analytical Services, Inc. and Morningstar Inc., leading
fund tracking and fund rating organizations, as well as several leading industry
publications. The Funds' experienced team of portfolio managers at Salomon
Brothers Asset Management frequently provide their expert commentary on CNNfn,
CNBC and Bloomberg News.


ECONOMIC AND MARKET TRENDS

The U.S. stock market in particular got off to a surprisingly strong start in
the first quarter of 1998. Investors were expecting the worst on the earnings
front in early 1998 in the aftermath of the Asian crisis. The anxiously awaited
fourth quarter earnings season, however, turned out to be better than the "worst
case" scenario. As a result, investors let out a big sigh of relief and embarked
on a furious buying spree. In a broad-based market rally, the S&P 500 Index
gained 14% while the Russell 2000 Index(R) advanced by about 10% in the first
quarter of 1998. (The S&P 500 Index is a capitalization-weighted measure of 500
widely held common stocks. The Russell 2000 Index is made up of 2,000
smaller-capitalized U.S.-based companies whose common stocks trade on either the
New York, American or NASDAQ stock exchanges). For the six months ended June 30,
1998, the S&P 500 Index returned 17.72% and the Russell 2000 Index(R) generated
a total return of 4.93%.

Stock market volatility increased significantly in the second quarter. Investor
focus shifted from the prospects of a Federal Reserve Board ("Fed") monetary
policy tightening due to the Asian crisis and eventually to hopes of reasonable
corporate earnings growth for the second quarter. Large-capitalization stocks
posted a gain for the second quarter while small-capitalization stocks declined
and fell farther behind their large-cap stock counterparts.

In fact, in the second quarter, the largest 50 companies in the S&P 500 Index
had an average total return of about 8%, while the Index's other 450 companies,
on average, declined. This emphasis on large-cap growth stocks means that
value-oriented investment strategies generally lagged the market for the first
six

months of 1998. (Value investing means investing in stocks that are selling
for less than their intrinsic value, in the belief that the market will
eventually recognize their value).

As a nation, we are more affluent than ever before, with much of that wealth
created in the last 15 years. We are benefiting from a world that has been
largely at peace since the official end of the Cold War in 1989. We are reaping
the fruits of the restructuring of American businesses in the 70s and 80s, and
we are benefiting from growth in worldwide demand for our products.

This unparalleled U.S. prosperity today is now being followed closely by Europe.
Companies in Europe are undergoing restructuring similar to that of the U.S. for
the last two decades. More and more, the inefficiencies of state-controlled
institutions in Europe are being replaced with the expansion of a free and more
competitive marketplace. As we approach the dawn of a new millennium, these
positive developments have enabled both the U.S. and most of Europe to
experience the greatest peace and prosperity in generations.

The rapid rise of global markets in recent years has been helped in no small
measure with the aid of sophisticated monetary policy. In the U.S.,
policy-making bodies, such as the Fed, coupled with technology-led productivity
gains, have controlled inflation to the extent that it's not a significant
factor in the U.S. economy today. U.S. bond yields have stayed in a fairly
narrow range as the U.S. economy has continued to grow without any signs of
accelerating inflation. For the six months ended June 30, 1998, the Lehman
Brothers Aggregate Bond Index returned 3.93%. (The Lehman Brothers Aggregate
Bond Index is composed of the Government/Corporate Bond Index, the Asset-Backed
Securities Index and includes U.S. Treasury issues, agency issues, corporate
bond issues and mortgage-backed issues.)

In Europe, the move to a common currency has forced both fiscal and monetary
policy to accomplish the same objective of bringing inflation and interest rates
down significantly in countries such as Italy and Spain. As interest rates have
come down, investment funds have flowed into stock markets, which, in turn, have
helped propel dramatic gains in the U.S. and European financial markets.

Now, the developing world is taking its cue from the U.S. and Europe. Perhaps
the most meaningful example is Latin America, where, after a very rocky period
in the last decade, monetary and fiscal policy reforms have stabilized economies
and established a base for solid and sustainable future growth. Yet, while the
underlying factors are very positive, a large part of the world continues to be
fragile both economically and politically.

Currently, parts of Asia are not enjoying growth and prosperity, particularly
Japan, Southeast Asia and Korea, where extraordinary



                                                                               3

economic growth and expansion during the last several decades resulted in
overheated and overextended financial conditions that are currently in the
painful process of readjusting. In addition, Russia is now in difficulty as its
political and financial infrastructure has not been able to keep pace with the
State's rapid conversion to a capitalistic economy.

There are some signs that the bull market in U.S. stocks may be slowing down,
and with market volatility on the rise, unforeseen outside factors are having a
pronounced impact on the markets as the debate between bulls and bears escalates
and investor uncertainty rises. For example, the situation in Iran, year-2000
computer problems, the Clinton scandals and the crisis in Asia and Russia are
all global events that trigger market corrections. On the other hand, U.S.
economic growth is still strong, inflation appears to be subdued and wage
pressures in the U.S. remain moderate, conditions that are generally favorable
for U.S. equities and may cause the unprecedented bull run to continue.


CONCLUSION

We foresee a slower U.S. economy for the remainder of 1998. The absence of
inflationary pressures should keep long-term bond yields below 6% while the
combination of lofty valuations and slower corporate earnings growth could find
stocks at the upper end of a trading range for the rest of the year. Investors
globally continue to be concerned with the implications and opportunities
arising as a result of Asia's economic contraction. Other emerging markets have
also been a source of anxiety - most specifically Russia, which recently
devalued its currency. We think that significant capital must be committed to
Asia to recapitalize wounded financial institutions.

Commentaries from the Funds' managers follows, beginning on page six. On behalf
of everyone here at Salomon Brothers Asset Management, thank you for your
investment in the Salomon Brothers Investment Series. We look forward to helping
you pursue your financial goals in the years to come.


Sincerely,

         ASIA GROWTH FUND


INVESTMENT OBJECTIVE AND STRATEGY

The Salomon Brothers Asia Growth Fund seeks long-term capital appreciation. The
Fund invests at least 65% of total assets in the equity and equity-related
securities of companies located in Asian countries. Areas considered for
investments includes but are not limited to, China, Hong Kong, India, Indonesia,
South Korea, Malaysia, Philippines,Singapore, Thailand, and Taiwan. In seeking
to capture high long-term returns with volatility in line with or lower than
that usually experienced in the Asian markets, the Fund will allocate its assets
among countries and industries believed by the portfolio manager to be most
likely to benefit from positive regional economic trends.

for day-to-day Fund management.


PERFORMANCE UPDATE

The Asia Growth Fund's Class A shares returned - 23.93% for the six-month period
ended June 30, 1998. This compares favorably to the Morgan Stanley Capital
International All Country Asia Free Ex-Japan Index total return of - 26.23% for
the same period. In addition, the Lipper Analytical Services, Inc. Pacific
ex-Japan funds had a total return of - 23.69% during the same period. (Lipper is
a major fund-tracking organization.)

MARKET REVIEW AND PORTFOLIO HIGHLIGHTS

Asia's markets continued to underperform versus world equity indices as what was
perceived as a slowdown in economic growth in the region last year evolved into
a full-fledged recession and well-publicized financial crisis. South Asian
markets -- especially Indonesia, Malaysia, Thailand, the Philippines and, by
extension, Singapore -- were the most affected with their 1998 economic growth
forecasts significantly reduced to negative levels. Corporations reported poor
results on the back of this depressed growth environment and banks increased
their provisioning significantly to deal with rising non-performing loans.

In contrast, North Asian markets continued to outperform their South Asian
counterparts. The least affected market, Taiwan, reported slightly higher growth
levels and its corporations, especially in the technology industry, continue to
benefit from lower local currency input costs and a buoyant U.S. technology
industry. Korean authorities' efforts to implement International Monetary Fund
(IMF) austerity and reform measures appeared to be paying off with Korean bond
and currency markets strengthening significantly in the first half of 1998.

China continues to be the unknown factor in the area and its stated 8% Gross
Domestic Product (GDP) growth target for 1998 looks increasingly difficult to
achieve given Asia's financial turmoil. As a result, a fair amount of pressure
is being placed on China's currency to be devalued to levels more consistent
with other regional currencies. Overall, most Asian markets are technically well
oversold and seem to be discounting the worst possible business environment in
Asia.

As a result of the region's ongoing volatility, the Fund's portfolio cash
weightings are likely to remain at higher levels than normal. We see value
emerging in China-sensitive markets that have been heavily sold off on the back
of Yuan devaluation worries. For example, shares of companies that have no
exposure to Asia and no currency mismatch for their asset/liabilities mix, and
exhibit earnings growth levels of 10% to 15% are currently selling at extremely
low P/E and cash multiples and steep discount to book values.


MARKET OUTLOOK

In our view, the most important factors for Asia to stage a sustainable economic
recovery are:

 . A credible and permanent fiscal stimulus coupled with effective banking
  reforms from Japan

 . A commitment from the Chinese authorities to continue reforms of state-
  owned enterprises and adjust the currency

Deflationary forces in the region mean that the macro outlook is likely to
remain depressed for some time. Moreover, Asia's corporate sector is unlikely to
generate any earnings growth as companies continue to deal with potentially
damaging credit issues and overextended balance sheets. We are likely to witness
increasing pressure on the "last man standing" of regional fixed-exchange-rate
systems -- the Hong Kong Dollar ("HKD") peg as regional currency devaluation
pressures rise. Although we believe that the HKD peg -- should hold for
socio-political reasons such as the stability of Hong Kong's society, it is not
inconceivable that the peg will come under pressure and the patience of
authorities is likely to be tested yet again.

The prospect of higher HKD interest rates in a market dominated by property and
financial assets is not encouraging. We are therefore rethinking our longer-term
overweight stance toward Hong Kong stocks that now seem to deserve significantly
lower weightings in light of current circumstances. Yet, valuations in Asia are
at extremely low levels and seem to discount an indefinite crisis scenario. We
believe that value can be found in select Asian markets and securities given the
severe state of dislocation in most of Asia's financial markets.

We believe that Asia's markets have become an attractive case study for value
investing. If a correction happens in the U.S. stock market, the negative
correlation between Asian market returns and U.S. and European stocks could mean
that Asia's markets may ultimately perform better.

[LOGO] THE SALOMON BROTHERS
        CAPITAL FUND


INVESTMENT OBJECTIVE AND STRATEGY 

The Capital Fund seeks capital appreciation through investment primarily in
common stocks or securities convertible into common stocks. The Fund seeks to
achieve its investment objective through investments in securities that are
believed to have above-average price appreciation potential. Such investments
may also involve above-average risk. The Fund may invest in seasoned,
established companies, relatively small new companies as well as new issues. The
Fund will not invest more than 25% of its assets in any particular industry.


THE FUND MANAGER

[PHOTO] Ross Margolies, Managing Director and Portfolio Manager at Salomon
Brothers Asset Management Inc, has 17 years of investment industry experience in
the equity, convertible and high yield markets. Mr. Margolies is primarily
responsible for day-to-day Fund management.


PERFORMANCE UPDATE

The Capital Fund's Class A shares returned 15.24% for the six months ended June
30, 1998. This compares with a return of 15.11% for the Russell 3000 Index((R)),
17.72% for the S&P 500 Index and 12.85% for the Lipper Analytical Services, Inc.
capital appreciation average. (The Russell 3000 Index(R) is a market
capitalization weighted index made up of the 3000 largest U.S. stocks in terms
of market capitalization and is the Fund's performance benchmark.)


MARKET REVIEW

The U.S. equity market continued its march onward and upward during the first
half of 1998. It was, however, a fractured market with a handful of large
capitalization company stocks accounting for an even more disproportionate
amount of the returns than they had over the last few years. This was due to the
perceived safety of these large, growing companies as well as their inclusion in
popular indices such as the S&P 500 Index.

We expect many of these stocks to continue to outperform as long as the market
continues to reward companies that play the Orwellian doublespeak game of
announcing that they will miss their earnings targets only to exceed the new
lower targets. Additionally, the current investment psychology of buying stocks
for the long term without regard to price and, in the extreme, simply buying the
stocks in a popular index in the exact proportions that they appear in the
index, has led to a "commodization" of both stocks and the equity market. Thus,
the large capitalization portion of the stock market attracts capital from
investors whose intent is to buy "stock," as opposed to shares in companies.
This is one of the few possible explanations for the market's rise in the face
of weaker earnings prospects and the higher risk business environment that most
companies with global exposure face.


PORTFOLIO HIGHLIGHTS

The Capital Fund -- which uses a bottom-up approach to stock selection --
maintained its strategy of owning attractive stocks in all categories. The
first-half performance of the Capital Fund largely reflects our strategy of
weighing risk and potential reward as well as our focus on a diversified all
capitalization ("cap") investment strategy.

As of June 30, 1998, 59% of our positions were in small- or mid-cap company
stocks. We were particularly satisfied with the first half outperformance of the
Fund in light of the fact that the small- and mid-cap market sectors materially
underperformed large-cap stocks. Our stock selection within the small- and
mid-cap sections led to the Fund's outperformance.

8
<PAGE>
 
Key contributors to the Fund's first half of performance included cable, media
and telecom stocks  such as Cablevision, Frontier Corp., NTL Inc., WorldCom and
Viacom, and retailers such as Costco, Food Lion and Federated. Our biggest drag
on performance was our large weighting in tobacco stocks such as Philip Morris,
RJR Nabisco and Loews. Technology was generally a positive contributor as our
largest weighted positions (including Plantronics and Seagate) were winners.
Lastly, we cut our losses in Fine Host common stock and moved up in the capital
structure into its distressed convertible bonds.


MARKET OUTLOOK

The near-term outlook for corporate earnings is weak while the ongoing macro
environment of low interest rates and low inflation is very positive for
equities. Weakness in Asian and other economies seems to finally be biting into
the strength of many Western economies. As portfolio managers, we are walking a
tightrope that seems to get stretched further and thinner each quarter. While
the returns are exhilarating, missteps are punished by dramatic falls in price.

Cash is at low levels as we have found many attractive ideas. We believe that
the best way to manage in the current environment is to count on the twin safety
nets of valuation discipline and broad diversification among different types of
companies to help cushion our missteps. While individual position concentration
has risen, as we expect it to when we have strong confidence in our stock
selections, the Fund's portfolio has low sector concentration other than in
tobacco. The Fund's portfolio is currently skewed towards smaller-sized company
stocks and relatively low P/E multiple stocks.

For the balance of the year, we expect the Fund's weightings in technology to
continue to grow and we expect an opportunity to rebuild our energy positions.
We also expect to maintain or increase our tobacco positions. During the next 12
to 18 months, we expect to see a resolution to the debate between health
officials' position regarding the dangers of cigarette smoking and the tobacco
industry's civil libertarian position for the right of adults to use a dangerous
but still legal product. Our current view is that this resolution will not cause
the tobacco holding companies to go bankrupt and will allow them to engage in
financial and restructuring transactions, which will unlock value for their
shareholders.

                                                                               9

THE SALOMON BROTHERS
  INVESTORS FUND


INVESTMENT OBJECTIVE AND STRATEGY 

The Salomon Brothers Investors Fund seeks long-term growth of capital. Current
income is a secondary objective. The Fund invests primarily in common stocks
listed on the New York Stock Exchange and other U.S. exchanges. The portfolio
managers generally favor large-capitalization stocks representing well-known
companies with good growth potential at a reasonable price.


PERFORMANCE UPDATE

The Investors Fund's Class A shares returned 12.06% for the six-month period
ended June 30, 1998 compared to the S&P 500 Index, which returned 17.72% and the
Lipper Analytical Services, Inc. growth and income fund peer group average,
which returned 12.11%.


MARKET REVIEW AND PORTFOLIO HIGHLIGHTS 

Although the Fund performed in line with its peer group average, the performance
lagged the S&P 500 Index. The S&P 500 benefited from the continued leadership of
large-capitalization growth stocks. Five stocks alone -- Microsoft, Lucent,
General Electric, Wal-Mart and Coca-Cola -- accounted for almost one quarter of
the S&P 500's six-month return. Beyond a select group of large-cap growth
stocks, however, most stocks underperformed the benchmark indices.

While Morningstar Inc.'s large-cap growth index returned 20.3% in the six-month
period, the large-cap value index returned only 10.3%. The Russell 2000
Index(R) -- which is made up of smaller-sized companies -- returned an even
lower 4.93%. Despite the recent outperformance of large-cap growth stocks, we
remain committed to our discipline of identifying value in the marketplace. We
believe that strict adherence to our investment principles should prove to be
rewarding for our shareholders over time.

Economic turmoil in Asia affected investment performance in the United States as
investors focused on defensive sectors of the market, including pharmaceuticals,
consumer products and telecommunications companies. Commodity and cyclical
companies underperformed in the second quarter as commodity prices continued to
fall and GDP growth in the U.S. slowed to only 1.4%. Disinflation and slower
growth kept the Fed from raising interest rates, despite a tight labor market.

Significant contributors to the Fund's performance during the period under
review included Cablevision Systems, Warner Lambert, Liberty Media and WorldCom.
We believe the Fund's portfolio is well diversified, with overweighted positions
in sectors such as basic industries and transportation and underweighted
positions in the technology and health care sectors.

MARKET OUTLOOK

In the near term, our outlook for the market is cautious. In our opinion,
coporate earnings growth expectations for the second half of 1998 are still too
high. We believe the industries most vulnerable to further estimate cuts include
energy, basic industry and technology. Defensive sectors of the market with more
earnings stability remain expensive. We are also focusing on cyclical companies
where we believe that price declines are overdone. On a positive note, low
commodity prices and the strong U.S. dollar should keep inflation low, allowing
the favorable interest-rate environment to continue. Overall, the U.S. economy
is slowing but remains healthy. We therefore do not foresee a recession.

         TOTAL RETURN FUND


INVESTMENT OBJECTIVE AND STRATEGY 

The Fund seeks to obtain above-average income compared to a portfolio that
invests only in stocks. The Fund's secondary objective is to take advantage of
opportunities for growth of capital and income by investing in a variety of
asset classes including stocks, bonds and short-term obligations.

The Fund's equity investments have been in large-capitalization stocks that are
paying dividends greater than the S&P 500 Index average. With assets allocated
to investment-grade, high-yield and convertible securities, the bond portion of
the Fund's portfolio is distributed across a broader range of fixed income
instruments than most balanced funds. The Fund's strategic approach in the bond
market tends to raise its income potential and the variety of its bond holdings
also provides diversification benefits that the portfolio manager believes could
help to limit its volatility.

PERFORMANCE UPDATE

The Total Return Fund's Class A shares posted a return of 6.35% for the
six-month period ended June 30, 1998. This compares with a 10.80% total return
for a composite index of 50% Salomon Brothers Broad Investment Grade Bond Index
and 50% S&P 500, and 8.95% for the Lipper Analytical Services, Inc. balanced
fund peer group average.


MARKET REVIEW AND PORTFOLIO HIGHLIGHTS 

The stock market has developed a split personality of late. The very largest-
capitalization company stocks have run away from the pack while many other kinds
of stocks have been in a bear market for some months. The Total Return Fund has
been influenced by these recent events. We follow a value investment strategy
with an emphasis on seeking to deliver above-average income. This investment
style has been temporarily out of fashion, but we believe this is just another
market cycle. The Fund's performance benefited when value investing was in favor
in 1995 and 1996. Therefore, we plan to stick to our value investing style and
identify situations that are currently under stress but still have, in our
opinion, good long-term prospects. Examples of investments we have made that
typify this approach include real estate investment trusts ("REITs"), Amerada
Hess and Union Pacific.

In the bond portion of the Fund, we have continued to move toward high-grade
bonds and have decreased our exposure to high-yield bonds where yield spreads
had narrowed. Toward the end of the second quarter, when yield spreads widened,
we saw some opportunities to move back into some high-yield securities.


MARKET OUTLOOK

The U.S. stock market is fully priced without any visible acceleration in
earnings. We expect corporate earnings to slow for the next several quarters
and, therefore, we expect the stock market to become more volatile. We believe
the merits of investing in a balanced fund like the Total Return Fund that
offers less potential volatility should become more apparent in the months
ahead.

[LOGO] THE SALOMON BROTHERS
         HIGH YIELD BOND FUND


INVESTMENT OBJECTIVE AND STRATEGY 

The Salomon High Yield Bond Fund seeks to maximize current income by investing
primarily in a diversified portfolio of high-yield bonds rated in medium of
lower categories. As a secondary objective, the Fund seeks capital appreciation.

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. (Moody's and S&P are two major
credit reporting and bond rating agencies.) A key component of the Fund's
overall investment strategy is to determine the optimal asset allocation between
domestic high-yield bonds and international U.S. dollar-denominated bonds such
as Brady Bonds and lower-rated sovereign debt.


- --------------------------------------------------------------------------------
THE FUND MANAGER
- --------------------------------------------------------------------------------

[PHOTO] Peter J. Wilby, CFA, Managing Director and Senior Portfolio Manager at
Salomon Brothers Asset Management Inc, has 18 years of investment industry
experience principally in the high-yield and emerging debt markets. Mr. Wilby is
primarily responsible for the day-to-day management of the High Yield Bond Fund.


PERFORMANCE UPDATE

During the six-month period ended June 30, 1998, the Salomon Brothers High Yield
Bond Fund's Class A shares posted a return of 1.78%. This performance compares
with the 5.14% return for the high-yield bond market, as measured by the Salomon
Brothers High Yield Market Index, and a 4.42% return for the Lipper Analytical
Services, Inc. high current yield fund peer group average. In addition, this
compares to a -1.08% return for the J.P. Morgan Emerging Market Bond Index Plus,
a standard benchmark for the emerging debt market. During the reporting period,
the Fund's performance was hurt by its allocation in emerging markets debt,
which accounted for approximately 27% of the Fund's total net assets.


MARKET REVIEW AND PORTFOLIO HIGHLIGHTS 

In the first part of the six months ended June 30, 1998, corporate earnings and
credit quality were generally very good and supported credit spread tightening,
or reduction of the risk premium over U.S. Treasury bills. The high-yield bond
market's firmness appeared to be due to several factors, including a high level
of cash in the market, a strong rally in the U.S. Treasury market and strong
demand from both retail and institutional buyers. High-yield mutual funds were
aggressive buyers, as most funds experienced record inflows during the period.
Collateralized Bond Obligations (CBOs), insurance companies, pension funds and
other institutional buyers have also been active participants in the high-yield
bond market.

The high-yield bond market reversed its positive trend in the second quarter of
1998. Investors became increasingly concerned with the impact of fundamental
problems in Japan, Russia and Southeast Asia, and a "flight-to-quality," or a
reduction in investors' risk appetites, ensued. Technical conditions in the
high-yield bond market were also weak, due to heavy new issuance of more U.S.
high-yield bonds against a backdrop of heightened investor concerns. Toward
quarter-end, however, new issuance began to slow, bringing supply and demand
closer to equilibrium. In addition, the proposed buyout of TCI by AT&T and
continued merger and acquisition activity in the cable/media sector helped
provide a more positive tone to the market.

Leisure/lodging, retail stores, technology, cable & media and gaming were
outperforming industries during the six months ended June 30, 1998. The
performance of these industries was driven by the continued strength of U.S.
consumer spending, which was buoyed by rising incomes and double-digit gains in
the U.S. stock market. Underperforming industries during the reporting period
included auto manufacturing, energy, publishing, supermarkets and textile &
apparel. Reasons for the sectors underperforming were varied, but a continued
theme is economic weakness in Asia.

The emerging debt markets were slightly negative during the six months ended
June 30, 1998 and posted a return of -1.08% as measured by the J.P. Morgan
Emerging Market Bond Index Plus during that period. In comparison, the Salomon
Brothers Broad Investment Grade Bond Index, a proxy for investment-grade bonds,
posted a return of 3.97%.

During the reporting period, we continued to believe that the market risk in
Asia had not disappeared. Events leading up to January 1998, however, increased
our confidence in global emerging market bond prospects. It seemed to us that
Asian countries were beginning to take tangible steps to combat the weakness in
their currencies. For example, Korea exchanged over $20 billion in maturing
short-term debt for longer-term bonds and subscribed to an IMF reform package;
Thailand and Malaysia began to implement many IMF reforms; and China reaffirmed
its commitment to maintaining Hong Kong's U.S. dollar currency peg.
Consequently, we began to increase our exposure to the market. We increased our
exposure to those countries that had solid fundamentals and were not excessively
reliant on the international capital markets, but were sold off in sympathy with
Asia. Additionally, we continued to focus our investing in the U.S. dollar debt
sector of the market, as opposed to the local currency markets.

For the six-month period ended June 30, 1998, outperformers in the emerging debt
market included Argentina, Brazil, Mexico, Panama, The Philippines, Morocco,
Bulgaria and Poland. Underperformers for the period included Ecuador, Venezuela,
Peru and Russia, all driven down by world events and declined in commodity
prices.

[LOGO] THE SALOMON BROTHERS
         STRATEGIC BOND FUND


INVESTMENT OBJECTIVE AND STRATEGY

The Salomon Brothers Strategic Bond Fund seeks a high level of current income.
The Fund seeks to achieve its objective by investing in a globally diverse
portfolio of fixed-income securities. As a secondary objective, the Fund seeks
capital appreciation. Assets of the Fund may be deployed among various sectors
of the global bond markets, depending on portfolio managers' analysis of current
economic and market conditions and the relative risks and opportunities
presented by the various market segments.


PERFORMANCE UPDATE

For the six-month period ended June 30, 1998, the Strategic Bond Fund's Class A
shares posted a 2.33% total return without sales charge. This compares with the
3.96% return for the Salomon Brothers Broad Investment Grade Bond Index and the
2.71% return for the Lipper Analytical Services, Inc. multi-sector income fund
peer group average.


MARKET REVIEW AND PORTFOLIO HIGHLIGHTS 

The performance of the U.S. economy exceeded expectations during the first six
months of 1998. Low long-term interest rates, abundant money supply growth and
new highs in the stock markets were some of the factors that contributed to the
U.S. economy's healthy performance. In addition, investors concerned about
developments in Asia gravitated to the U.S. Treasury securities market as a
"safe haven."

As a result, the yield on the long bond reached its lowest level -- 5.57% --
since the U.S. government began regular sales of securities in 1977. The yield
curve flattened with spreads between the two-year U.S. Treasury note and 30-year
U.S. Treasury bond tightening to 15 basis points as of June 30, 1998. (The yield
curve shows the difference between short- and long-term rates. A basis point is
one one-hundredth of a percent.) This enabled long-term U.S. Treasuries to
out perform shorter term bonds.

During the first half of the year, all major credit-sensitive bond sectors
experienced heightened volatility. Emerging markets debt, which rallied in the
first quarter based on an optimistic outlook for reforms in Asia, gave up its
gains as attempts to implement reforms in the troubled region met with some
resistance. Events in Russia, India and Pakistan that unfolded in the second
quarter compounded existing challenges in Southeast Asia. Moreover, Japan's
economic and banking system problems have become more prominent and led to a
weakening of the Japanese yen versus the U.S. dollar. In addition to Asia's
economic problems, the markets had to endure a crisis of confidence in Russia.
Russia raised interest rates on overnight money to 150% at one point in order to
fund their liabilities. Russia's problems led to a sector-wide sell-off of
emerging markets debt.

<PAGE>
 
In the emerging markets debt sector, the Fund lightened up on its Russian
exposure and added to holdings in Bulgaria and Peru. Mexico and Argentina
continue to be core Fund holdings as we believe the fundamentals behind
these Latin American countries remain strong.

During the six months ended June 30, 1998, the high-yield bond market posted a
5.1% return. However, volatility in the high-yield bond market in the second
quarter increased. In addition, many corporations issued record levels of debt
to take advantage of low interest rates. This pressured the high-yield bond
market and, as a result, the yield spreads on high-yield bonds versus comparable
U.S. Treasuries rose to about 380 basis points, about 100 basis points higher
than the lows set in August of 1997. We were not deterred by the technically
induced spread widening and maintained the Fund's weightings in high-yield
bonds. In addition, we maintained the Fund's high credit quality standards
although a large number of new deals came to market with weaker underlying
fundamentals. We continue to seek opportunities to upgrade the Fund's credit
quality and we remain positive on high-yield bonds.


MARKET OUTLOOK

We believe that the Fed's monetary policy is firmly on hold for the time being
supported by few signs of inflation and the persistent crisis in Asia. We intend
to continue our strategy of investing in higher-yielding bond sectors that we
believe will provide superior returns over time.

         NATIONAL INTERMEDIATE
         MUNICIPAL FUND


INVESTMENT OBJECTIVE AND STRATEGY 

The Salomon Brothers National Intermediate Municipal Fund seeks to achieve a
high level of current income exempt from regular federal income taxes. 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. Please note that all or a portion of the Fund's income may be
subject to the federal alternative minimum tax (AMT).

Management Inc, has 20 years of investment industry experience. Ms. Whyte is
responsible for day-to-day Fund management.


PERFORMANCE UPDATE

For the six-month period ended June 30, 1998, the National Intermediate
Municipal Fund's Class A shares had a total return of 2.00% and slightly 
underperformed versus the return of 2.05% for the average intermediate
municipal debt fund as measured by Lipper Analytical Services, Inc. and the
2.34% return for the weighted average of the Lehman Brothers 1-10 year Municipal
Bond Index.


MARKET REVIEW

Returns for municipal bonds were favorable during the first half of 1998. U.S.
fixed-income securities benefited from benign inflation and the economic and
political turmoil in Asia. Treasuries were sought as a safe-haven by worldwide
investors and it was anticipated that the Asian problems would slow our economy.

Price advances for municipal bonds were tempered as compared to Treasuries due
to a near record pace of tax-exempt new issuance for the first six months of the
year. State and local governments took advantage of the current low interest
rate environment by issuing almost $146 billion of new debt during this time
period. Demand for municipals remains concentrated by property and casualty
insurance companies, corporations, mutual funds and, to a lesser degree,
individual investors. Year-to-date municipal bond new issue supply is 51% ahead
of 1997 levels.

Our philosophy of focusing on long-term fundamentals, rigorous credit analysis
and sector selection remains the credo for managing the Fund. Purchases in the
Fund have been concentrated in seven- to ten-year maturities and on high-quality
issues as credit quality spreads remained narrow.


MARKET OUTLOOK

The municipal new issue supply is likely to slow somewhat as is typical in the
summer months. We do expect a resurgence in the new issue calendar after the
Labor Day holiday through the early fall. Municipals are historically
undervalued due to the heavy supply this year. We expect them to remain
extremely attractive as supply is plentiful.

compares favorably with the Lipper Analytical Services, Inc. short-intermediate
U.S. government bond fund peer group average return of 2.84% for the same
period.


MARKET REVIEW AND PORTFOLIO HIGHLIGHTS 

The U.S. bond market began the first quarter of 1998 in dramatic fashion as the
continuation of late 1997's flight to quality trade pushed interest rates lower.
By the end of the first full week of trading, short-term interest rates were
down 50 basis points as the Asian financial crisis showed no signs of abating.
Yet, to the surprise of many market participants, the Asian financial crisis
appeared to be resolved later in January when Asian currencies stabilized and
their equity markets began to rally. As a result, interest rates reversed course
and rose both in February and March to end the quarter barely changed from
January 1, 1998 levels.

Turbulence in world financial markets reappeared and the U.S. bond market
registered solid gains in the second quarter of 1998. Weakness in Japan took
center stage with the U.S. dollar/yen exchange rate serving as a barometer for
market sentiment. The yen deteriorated by 4.3% versus the U.S. dollar over the
quarter despite concerted foreign currency exchange intervention by the U.S. and
Japan. All of the Asian difficulties, plus instability in Russia, rattled equity
markets and sent capital surging into the safe haven of U.S. Treasuries.

Due to the economic problems in Asia, we began the year with a fairly
constructive view of U.S. fixed-income markets. We believed Asia would slow U.S.
economic growth and push inflation lower, which would enable interest rates, in
particular long-term rates, to move modestly lower, pushing bond prices higher
during 1998. To take advantage of our expectations for lower rates and a flatter
yield curve, we kept the Fund's assets in longer maturities and over weighted
discount mortgage pass-throughs. These strategies were key to the Fund's
out performance thus far in 1998.


MARKET OUTLOOK

Looking ahead, Asian turmoil appears to have overshadowed feint warnings of
tightening from the Fed Chairman Alan Greenspan. Near term, current interest
rate levels will be difficult to sustain without a significant pullback in
equities or a further sharp rise in the U.S. dollar. However, any backups in
yields will likely be met with substantial buying interest. Overall, we expect a
relatively benign interest rate environment during the next six to twelve month
period and we expect mortgages to outperform U.S. Treasuries.

FOOTNOTES

 (*)   Return does not reflect the deduction of sales charge.

 (**)  Class A shares reflect the deduction of the maximum 4.75% sales charge.
       Class B & C shares reflect the maximum contingent deferred sales charge
       of 5.00% and 1.00%, respectively. Class O shares have no initial or
       contingent deferred sales charge.

(***)  As a percentage of net assets. 
(****) As a percentage of market value.

  +    Lipper Analytical Services, Inc., 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 effect of sales charges. Accordingly, the result in this table for
       the Class A, Class B and Class C shares of each Fund do not reflect the
       effects of the sales charges applicable to each Class. Lipper performance
       results represent changes in net asset value, adjusted to reflect
       reinvestment of dividends and capital gains.

 ++    When measured against the Fund's benchmark, the Salomon Brothers High-
       Yield Market Index, these industries have a greater percentage allocation
       within the Fund, and are therefore considered "overweighted."




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). Class A shares
reflect the deduction of an annual 0.25% 12b-1fee. Class B & 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. Class O shares are only available to
existing Class O shareholders. 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 imposed by SBAM to limit total Fund
operating expenses. Absent this expense cap, Fund returns would be lower.
Expense caps may be revised or terminated at any time.

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, the Salomon Brothers Investors Fund Inc (the
"Investors Fund") and the Salomon Brothers Capital Fund Inc (the "Capital
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 Asia Growth Fund (the
"Asia Growth Fund"), Salomon Brothers Small Cap Growth Fund (the "Small Cap
Fund"), Salomon Brothers Total Return Fund (the "Total Return Fund"), Salomon
Brothers High Yield Bond Fund (the "High Yield Bond Fund"), Salomon Brothers
Strategic Bond Fund (the "Strategic 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 New York Municipal Money Market Fund (the "New York
Municipal Money Fund"), Salomon Brothers Cash Management Fund (the "Cash
Management Fund"), and Salomon Brothers Institutional Money Market Fund (the
"Institutional Money Market Fund"). As of the date of this report the Small Cap
Fund had not yet commenced operations. Separate financial statements are
prepared for the Institutional Money Market Fund which is 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 and the Capital Fund, a non-diversified open-end management investment
company incorporated in Maryland on August 23, 1976. 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 Asia Growth Fund's objective is to seek
long-term capital appreciation; the Capital Fund's objective is to seek capital
appreciation through investments primarily in common stock, or securities
convertible into common stocks, which are believed to have above average price
appreciation potential; the Investors Fund's primary objective is to seek long-
term growth of capital; the Total Return Fund's primary objective is to obtain
above-average income (compared to a portfolio entirely invested in equity
securities); 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 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 New York Municipal Money Fund's objective is to
seek as high a level of current income exempt from federal income taxes, New
York State and New York City personal income taxes consistent with liquidity
and the stability of principal; 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.
 
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 commenced investment operations. A summary of those expenditures that
remain as of June 30, 1998 for each Fund is as follows:

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.
 
                                                                              81

 (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 are valued at amortized cost
which approximates market value. If a Fund, other than the New York Municipal
Money Fund and Cash Management Fund, acquires such securities with more than 60
days remaining to maturity, they are valued at current market value, until the
60th day prior to maturity, and are then valued on an amortized cost basis.
 
 Portfolio securities for the New York Municipal Money Fund and 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.
 
 Prior governmental approval for foreign investments may be required under
certain circumstances in some emerging market countries, and the extent of
foreign investment in domestic companies may be subject to limitation in other
emerging market countries. Foreign ownership limitations also may be imposed by
the charters of individual companies in emerging market 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 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 Asia Growth Fund, Capital Fund, Investors Fund,
Total Return Fund, High Yield Bond Fund, Strategic Bond Fund, and National
Intermediate Municipal 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 is recognized. Outstanding contracts may 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 Total Return Fund, Strategic Bond Fund, and U.S.
Government Income 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

NOTES TO FINANCIAL STATEMENTS
(unaudited) (continued)
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, 1998 was approximately $11,510,000, $23,695,000, and $2,786,000 for
the Total Return Fund, Strategic Bond Fund, and U.S. Government Income 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) REVERSE REPURCHASE AGREEMENTS. Certain Funds may enter into reverse
repurchase agreements in which a Fund sells portfolio securities and agrees to
repurchase them from the buyer at a particular date and price. Whenever a Fund
enters into a reverse repurchase agreement, it establishes a segregated account
consisting of liquid assets in an amount at least equal to the repurchase price
marked to market daily (including accrued interest), and subsequently monitors
the account to ensure that such equivalent value is maintained. A Fund pays
interest on amounts obtained pursuant to reverse repurchase agreements. Reverse
repurchase agreements are considered to be borrowings by a Fund. Transactions
in reverse repurchase agreements for the Funds during the six months ended June
30, 1998 were as follows:

U.S. Government Income Fund................ $1,858,931     4.13%     $2,466,750
</TABLE>
 
 (G) FOREIGN CURRENCY TRANSLATION. The accounting records of each Fund are
maintained in U.S. dollars. Investment securities and other assets and
liabilities of the Asia Growth Fund, Capital Fund, Investors Fund, Total Return
Fund, High Yield Bond Fund, and Strategic Bond 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.
 
 (H) FORWARD FOREIGN CURRENCY CONTRACTS. The Asia Growth Fund, Capital Fund,
Investors Fund, Total Return Fund, High Yield Bond Fund, and Strategic Bond
Fund may enter into forward foreign currency contracts. 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.
 
 (I) LOAN PARTICIPATIONS. The Total Return Fund, High Yield Bond Fund, and
Strategic Bond 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, 1998 were
$40,151,002 and $2,936,547, respectively.
 
                                                                              83
<PAGE>
 
NOTES TO FINANCIAL STATEMENTS
(unaudited) (continued)
 
 (J) FEDERAL INCOME TAXES. Each Fund has complied with the requirements of the
Internal Revenue Code applicable to regulated investment companies and
distributed all of its income, including any net realized gains, to
shareholders. Therefore, no Federal income tax or excise tax provision is
required for such Funds.
 
 (K) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends from net investment
income on the shares of each of the Funds (except the Asia Growth Fund,
Investors Fund, and Capital 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 and the
Capital 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.
 
 (L) 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.
 
 (M) 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.
 
 (N) OTHER. Investment transactions are recorded as of the trade date. Dividend
income is recorded on the ex-dividend date (except for the Asia Growth Fund,
where certain dividends may be recorded as soon as the Fund is informed of such
dividends). 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), 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.
 
 (O) CASH FLOW INFORMATION. Statement of Financial Accounting Standards Number
102 generally exempts entities such as the Funds from reporting a Statement of
Cash Flows. However, the amount and nature of certain activities entered into
by the Total Return Fund, Strategic Bond Fund, and U.S. Government Income Fund
may be considered financing arrangements, which may require the presentation of
a Statement of Cash Flows. General investing and operating activities of the
Funds are reported in the Statement of Changes in Net Assets and additional
information on cash receipts and cash payments are presented in the Statement
of Cash Flows. Accounting practices that do not affect reporting activities on
a cash basis include carrying investments at value and amortizing discounts or
premiums on debt obligations.
 
2. MANAGEMENT FEE AND OTHER AGREEMENTS
 
Each Fund retains SBAM, an indirect, wholly-owned subsidiary of Travelers Group
Inc. ("Travelers") to act as investment manager of each Fund, subject to the
supervision by the Board of Directors of each Fund. Each management agreement
with SBAM was most recently approved by shareholders at a special meeting held
on January 14, 1998. Approval of the agreements were necessary due to the
merger of Salomon Inc, which had been the ultimate parent company of the
investment manager, with and into Smith Barney Holdings Inc., a subsidiary of
Travelers, which occurred on November 28, 1997. On such date, Travelers became
the ultimate parent of SBAM.

NOTES TO FINANCIAL STATEMENTS
(unaudited) (continued)
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 Capital Fund and Investors Fund) is payable monthly
and is based on the following annual percentages of each Fund's average daily
net assets: .80% for the Asia Growth Fund, .55% for the Total Return Fund, .75%
for the High Yield Bond Fund and Strategic Bond Fund, .50% for the National
Intermediate Municipal Fund, .60% for the U.S. Government Income Fund, .20% for
the New York Municipal Money Fund and Cash Management Fund. The management fee
for the Capital Fund is payable monthly and is based on the following annual
percentages of the Fund's average daily net assets: first $100 million--1%;
next $100 million--.75% ; next $200 million--.625%; excess over $400 million--
 .50%. SBAM Limited, an affiliate of SBAM, provides certain advisory services to
SBAM for the benefit of the Strategic Bond Fund, as well as, certain
administrative services for the Asia Growth Fund. SBAM Limited is compensated
by SBAM at no additional expense to the Strategic Bond Fund and Asia Growth
Fund. SBAM has retained 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.
 
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"). For the period
January 1, 1997 through April 28, 1997 the base fee was paid quarterly based on
the following annual percentages of the Fund's average daily net assets: first
$350 million--.50%; next $150 million--.40%; next $250 million--.375%; next
$250 million--.35%; excess over $1 billion--.30%. At its Annual Meeting on
April 29, 1997, the Fund's shareholders approved an amendment to the Fund's
Management Agreement between the Fund and SBAM to increase the base fee
component of the management fee. Accordingly, as of April 29, 1997, the base
fee is paid quarterly based on the following annual rates:
 
<TABLE>

Next $250 million..............................................      .500%
Over $1 billion................................................      .450%
</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 more percentage points.
For the rolling one-year period ended March 31, 1998, the investment record of
the S&P 500 Index exceeded the Investors Fund's performance by approximately
nine percent. For the rolling one-year period ended June 30, 1998, the
investment record of the S&P 500 Index exceeded the Investors Fund's
performance by approximately eight percent. As a result, base management fees
were decreased, in aggregate, by $307,143 for the six months ended June 30,
1998.
 
For the six months ended June 30, 1998, SBAM waived management fees of $67,638,
$282,353, $112,183, $80,989, $36,971, $42,271 and $32,757 for the Asia Growth
Fund, Total Return Fund, High Yield Bond Fund, Strategic Bond Fund, National
Intermediate Municipal Fund, U.S. Government Income Fund, and Cash Management
Fund, respectively, and voluntarily absorbed expenses of $97,825, $32,582, and
$31,492 for the Asia Growth Fund, National Intermediate Municipal Fund, and
U.S. Government Income Fund, respectively.
 
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 six months ended June 30, 1998,
credits earned on outstanding cash balances were used to reduce custodian fees.
 
 
                                                                              85

NOTES TO FINANCIAL STATEMENTS
(unaudited) (continued)
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 New York Municipal Money Fund and 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 New York
Municipal Money Fund and 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 $21,900, $14,952, and $3,600 were paid by the Capital
Fund, Investors Fund, and Total Return Fund, respectively, to Smith Barney Inc.
 
Salomon Brothers received $223,926 as its portion of the front-end sales charge
on sales of Class A shares of the Funds during the six months ended June 30,
1998. In addition, contingent deferred sales charges of $1,040,681 were paid to
Salomon Brothers in connection with redemptions of certain Class B and Class C
shares of the Funds during the six months ended June 30, 1998.

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 New York Municipal Money Fund and Cash Management Fund invest in money
market instruments maturing in thirteen months or less whose short-term credit
ratings are within the 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 Money Fund pursues its investment
objective by investing at least 80% of its net assets in obligations that are
exempt from 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 Money 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 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.
 
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 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. The 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.
 
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
 
                                                                              91

a result, the Fund will assume the credit risk of both the borrower and the
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.

 (SPer)share information calculated using the average shares outstanding
   method, which more accurately represents 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 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.

 (SPer)share information calculated using the average shares outstanding meth-
   od, which more accurately represents 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.

    31, 1995.
 (SPer)share information calculated using the average shares outstanding meth-
   od, which more accurately represents 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 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.

included in this report. The other portfolios of the Company are reported in a
separate report and are not included herein. 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.
 
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 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 in which 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 Travelers Group Inc. ("Travelers"), 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 agreement with
SBAM was most recently approved by shareholders at a special meeting held on
January 14, 1998. Approval of the agreement was necessary due to the merger of
Salomon Inc, which had been the ultimate parent company of the investment
manager, with and into Smith Barney Holdings Inc., a subsidiary of Travelers,
which occurred on November 28, 1997. The management fee to SBAM is payable
monthly and is based on an annual rate of .20% of the Fund's average daily net
assets.
 
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 the six
months ended June 30, 1998, SBAM voluntarily waived management fees of $152,794.
 
Investors Bank & Trust Company ("IBT") serves as custodian and administrator for
the Fund, which includes performing custodial and certain administrative
services in connection with the operation of the Fund.
 
The Fund has an agreement with Salomon Brothers Inc, an affiliate of SBAM, to
distribute its shares.
 
3. CAPITAL STOCK
 
At June 30, 1998, 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.
