February 16, 1996

To Our Shareholders:

We are pleased to provide this annual report for the period ended December 31,
1995 for the Salomon Brothers Investment Series, which includes the Salomon
Brothers Cash Management Fund, Salomon Brothers New York Municipal Bond Fund,
Salomon Brothers National Intermediate Municipal Fund, Salomon Brothers U.S.
Government Income Fund, Salomon Brothers High Yield Bond Fund, Salomon Brothers
Strategic Bond Fund, Salomon Brothers Total Return Fund and Salomon Brothers
Investors Fund. On the following pages, you will find a performance review for
each fund, their audited financial statements for the period ended December 31,
1995, the related report of independent accountants and other information about
the funds.

The stock market enjoyed a banner year in 1995, with the Standard & Poor's
Index of 500 stocks rising by 37.5% on a total return basis.  Volatility
remained low for the third year in a row. Moderate economic growth, low
inflation, declining interest rates and strong growth in corporate profits
created ideal conditions for the market. In the U.S., large capitalization
stocks led the advance, and technology, health care and financial services
companies were the best performing groups.

The bond market also experienced an impressive rally in 1995, as the Salomon
Brothers Broad Investment Grade Bond Index increased 18.5% for the year. The
rally was supported by signs of economic growth deceleration and an overall
shift in investor sentiment that the Federal Reserve Board would remain under
pressure to ease monetary policy by lowering interest rates. Investor sentiment
in the municipal bond market turned sharply negative in the second quarter,
when fears of a flat tax surfaced. These concerns began to dissipate at the end
of the year, and the market has performed relatively well versus Treasuries
since then.

Global economic weakness continues to dominate our thinking. In the U.S., there
has been ample confirmation of the uneven quality of the current expansion. Job
growth has slowed. Although housing starts have bounced back somewhat, it will
likely take a substantial drop in mortgage rates to trigger any meaningful
pickup in the months ahead. Despite weakness abroad, exports show surprising
vigor. The dollar's strengthening, however, could slow further growth in that
area. Although external demand for U.S. goods remains solid, domestic demand is
suffering as the economic expansion matures, consumer debt burdens grow and
income gains slow.

Reinforced by fiscal restraint, these factors point to a period of slower
growth that will encourage further easing of monetary policy by the Federal
Reserve. We continue to look for an economic environment characterized by slow
growth and low inflation.

Portfolio Review

NEW YORK MUNICIPAL BOND FUND

The New York Municipal Bond Fund commenced investment operations on February 1,
1993. On January 3, 1995 the Fund began offering Class A, Class B, Class C and
Class O Shares. The Fund seeks 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.

For the period January 3, 1995 through December 31, 1995, the Fund had a total
return exclusive of sales charges of 17.7% for Class A Shares, 17.0% for Class
B Shares, 17.0% for Class C Shares and 18.8% for Class O Shares. Total return
for the Fund including the effects of the maximum 4.75% front-end and any
applicable deferred sales charges was 12.1% for Class A Shares, 12.0% for Class
B Shares, 16.0% for Class C Shares and 18.8% for Class O Shares for the same
period. This compares with a total return of 19.0% for the twelve-month period
ended December 31, 1995 for the Lehman Brothers 7 Year through Long Municipal
Bond Index* and a 16.7% average of 88 New York Municipal Bond Funds tracked by
Lipper Analytical Services, Inc.

The Fund's underperformance, prior to the deduction of applicable sales
charges, relative to the benchmark was caused by our emphasis on income rather
than principal appreciation.

The portfolio contained a large percentage of longer maturity bonds and some
Baa/BBB rated credits. As interest rates fell during the year, investors began
purchasing lower rated investment grade bonds for additional yield. As a
result, the Fund not only benefited from the decline in interest rates, but
also from a relatively strong performance of many lower rated credits. Income
was enhanced by owning long maturity bonds, lower rated credits and by a number
of older high coupon bonds in the portfolio.

As the market rallied during 1995, many of the longer bonds began trading to
shorter calls, thus limiting their upside potential. Since we believed the bond
market would continue to appreciate in price, we repositioned the portfolio by
selling some of those bonds trading to their call. We then purchased current
coupon municipals to allow for continued price appreciation. Additionally, we
upgraded the average credit quality of the portfolio by selling some lower
rated credits which had performed relatively well and in our opinion no longer
offered the same value.

NATIONAL INTERMEDIATE MUNICIPAL FUND

The National Intermediate Municipal Fund seeks to achieve a high level of
current income which is exempt from regular Federal income taxes by investing
primarily in a portfolio of municipal securities.

For the period February 22, 1995 (commencement of investment operations)
through December 31, 1995, the Fund had a total return exclusive of sales
charges of 8.7% for Class A Shares, 8.0% for Class B Shares, 8.0% for Class C
Shares and 9.0% for Class O Shares. Total return for the Fund including the
effects of the maximum 4.75% front-end and any applicable deferred sales
charges was 3.6% for Class A Shares, 3.0% for Class B Shares, 7.0% for Class C
Shares and 9.0% for Class O Shares for the same period. This compares with a
total return of 9.2% for the Lehman Brothers 1-10 year Municipal Bond Index*
and an 8.4% average of 31 Intermediate Municipal Bond Funds tracked by Lipper
Analytical Services, Inc.

The Fund's modest underperformance, prior to the deduction of applicable sales
charges, relative to the benchmark was caused by our emphasis on current income
rather than principal appreciation.

During 1995, the average maturity of the Fund was toward the longer end of its
ten-year maturity constraint. The Fund's longer maturity bias enabled it to
participate in 1995's bond market rally. However, in accordance with its
investment objective, the Fund also held a significant number of higher coupon
bonds to bolster current income.

U.S. GOVERNMENT INCOME FUND

The U.S. Government Income Fund seeks to obtain a high level of current income
by investing under normal circumstances 100% of its assets in debt obligations
and mortgage-backed securities issued or guaranteed by the U.S. government, its
agencies or instrumentalities.

For the period February 22, 1995 (commencement of investment operations)
through December 31, 1995, the Fund had a total return exclusive of sales
charges of 9.5% for Class A Shares, 8.8% for Class B Shares, 8.8% for Class C
Shares and 9.7% for Class O Shares. Total return for the Fund including the
effects of the maximum 4.75% front-end and any applicable deferred sales
charges was 4.3% for Class A Shares, 3.8% for Class B Shares, 7.8% for Class C
Shares and 9.7% for Class O Shares for the same period. This compares with a
total return of 9.1% for the Salomon Brothers 1-5 year Treasury Bond Index* and
a 7.8% average of 138 Short-Term U.S. Government Bond Funds tracked by Lipper
Analytical Services, Inc.

The Fund, prior to the deduction of applicable sales charges, relative to the
benchmark, outperformed for Class A Shares and Class O Shares while
underperformed for Class B Shares and Class C Shares. The portfolio's average
maturity was relatively long compared to the benchmark during 1995. This
structure contributed significantly to the Fund's results. The Fund's
performance also benefited from its position in discount mortgage
pass-throughs. The Fund's strategy will continue to emphasize longer-term
instruments, given our view that interest rates will fall further.

Portfolio Review (continued)

HIGH YIELD BOND FUND

The High Yield Bond Fund seeks to maximize current income by investing
primarily in a diversified portfolio of high yield fixed-income securities
rated in medium or lower rating categories or determined by the investment
manager to be of comparable quality.

For the period February 22, 1995 (commencement of investment operations)
through December 31, 1995, the Fund had a total return exclusive of sales
charges of 16.6% for Class A Shares, 15.7% for Class B Shares, 15.8% for Class
C Shares and 16.8% for Class O Shares. Total return for the Fund including the
effects of the maximum 4.75% front-end and any applicable deferred sales
charges was 11.0% for Class A Shares, 10.7% for Class B Shares, 14.8% for Class
C Shares and 16.8% for Class O Shares for the same period. This compares with a
total return of 14.2% for the Salomon Brothers High Yield Market Index* and a
13.0% average of 153 High Yield Market Funds tracked by Lipper Analytical
Services, Inc.

The Fund's out-performance relative to the benchmark, prior to the deduction of
applicable sales charges, relative to the benchmark, was the result of the 20%
portfolio allocation to emerging market and high yield sovereign debt
securities during the year. Both were strong performers during the period. The
Fund started buying emerging markets and sovereign debt securities in
early 1995. The market at that time was declining as a result of the large
sell-off that followed the devaluation of the Mexican peso in December 1994. 
The Fund's allocation to this sector is in U.S. dollar-denominated government 
debt or Brady Bonds which declined as a side effect of the peso-denominated 
market sell-off. From February 28, 1995 to December 31, 1995 Brady Bonds 
generally returned 38.11% as measured by the Salomon Brothers Brady Bond Index.

Also contributing to the Fund's out-performance was a rotation in the portfolio
to more defensive, non-cyclical corporate debt issues. Non-cyclical debt
issues totaled 33.2% of the corporate bond portion of the portfolio at December
31, 1995. As U.S. economic growth slowed, non-cyclical issues out-performed
cyclical corporate debt issues significantly.

We continue to maintain a defensive posture in the Fund with a 15.7% allocation
in U.S. dollar-denominated international investments. We expect to rotate the
corporate debt exposure to more cyclical companies when the U.S. economy shows
signs of strengthening. We will reduce the allocation to emerging market
government bonds when we feel the market has completely recovered from last
year's sell-off.

STRATEGIC BOND FUND

The Strategic Bond Fund seeks a high level of current income by investing in a
globally diverse portfolio of fixed-income investments 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
best contribute to the achievement of the Fund's objective. As a secondary
objective, the Fund seeks capital appreciation.

For the period February 22, 1995 (commencement of investment operations)
through December 31, 1995, the Fund had a total return exclusive of sales
charges of 16.8% for Class A Shares, 16.1% for Class B Shares, 16.1% for Class
C Shares and 17.0% for Class O Shares. Total return for the Fund including the
effects of the maximum 4.75% front-end and any applicable deferred sales
charges was 11.3% for Class A Shares, 11.1% for Class B Shares, 15.1% for Class
C Shares and 17.0% for Class O Shares for the same period. This compares with a
total return of 13.5% for the Salomon Brothers Broad Investment Grade Index*
and a 14.5% average of 161 General Bond Funds tracked by Lipper Analytical
Services, Inc.

The Fund's out-performance, prior to deduction of applicable sales charges,
relative to the benchmark, was driven by significant positions in high yield
and emerging markets debt. The two sectors, accounting for 70% to 75% of
holdings in 1995, were the best performers in the fixed income markets last
year. The emerging debt markets achieved particularly strong performance in the
fourth quarter. The Fund's investment strategy continues to emphasize positions
in high yield bonds which should continue to perform well in a slow-growing
economic environment. The Fund also maintains positions in emerging debt
markets which are likely to benefit from increasing investor confidence and
participation.

TOTAL RETURN FUND

The Total Return Fund seeks to obtain above-average income compared to a
portfolio entirely invested in equity securities by investing in a broad
variety of securities including equity securities, fixed income securities and
short-term obligations. As a secondary objective, the Fund will seek to take
advantage of opportunities for growth of capital and income.

For the period September 11, 1995 (commencement of investment operations)
through December 31, 1995, the Fund had a total return exclusive of sales
charges of 6.7% for Class A Shares, 6.4% for Class B Shares, 6.5% for Class C
Shares and 6.9% for Class O Shares. Total return for the Fund including the
effects of the maximum 4.75% front-end and any applicable deferred sales
charges was 1.6% for Class A Shares, 1.4% for Class B Shares, 5.5% for Class C
Shares and 6.9% for Class O Shares for the same period. This compares with a
total return of 6.5% for a composite index of 50% Standard and Poor's 500
Composite Stock Price Index and 50% Salomon Brothers Broad Investment Grade
Bond Index and a 5.0% average of 30 Balanced Funds tracked by Lipper Analytical
Services, Inc.

The Fund's out-performance, prior to deduction of applicable sales charges,
relative to the benchmark was driven, in part, by portfolio allocations such as
high yield bonds and convertible securities. Significant sector concentrations
in the equity portfolio including an overweighted position in energy stocks
also contributed to positive performance. This diversification between stocks
and bonds is aimed at reducing the volatility of the Fund's performance over
the long term and at producing above-average current income compared to a
portfolio of stocks only.

In 1995, the stock market rose to historically high valuation levels. The high
levels were supported by record corporate profitability and substantially lower
interest rates. In 1996, we believe that earnings in cyclical stocks, such as
auto, paper, chemical and technology companies, may be disappointing in the
context of a slowing economy.

As a result of the large gains in the stock market in 1995, the Fund has
developed a somewhat conservative stance. Our current portfolio allocations are
approximately 45% equities, 40% bonds, 10% convertible and preferred securities
and 5% short-term investments. In terms of the bond allocation, we believe that
high yield bonds offer the most attractive relative value at this time. The
equity portfolio is overweighted in oil companies such as Amoco, Royal Dutch
Petroleum and Exxon due to an improving outlook for this industry sector as
well as the defensive character of their relatively high dividend yields. Other
major equity positions are in utilities and Real Estate Investment Trusts
(REITs).

INVESTORS FUND

The Investors Fund commenced operations on May 29, 1958. On January 3, 1995 the
Fund began offering Class A, Class B, Class C and Class O Shares. The Investors
Fund seeks long-term growth of capital by investing primarily in common stocks
of well-known companies with current income as a secondary goal.

Allan R. White, who previously shared primary responsibility for the day-to-day
portfolio management of the Fund with another senior portfolio manager, has
assumed sole responsibility for these matters. He is aided by Pamela Milunovich
as junior portfolio manager. A Vice President with the Fund's investment
advisor, Salomon Brothers Asset Management Inc, Ms. Milunovich brings 10 years
of experience to the Fund. In her role as Senior Analyst for Salomon Brothers
Asset Management Inc, Ms. Milunovich has been responsible for stock selection
in the financial, retail and computer service sectors.

For the period January 3, 1995 through December 31, 1995, the Fund had a total
return exclusive of sales charges of 35.3% for Class A Shares, 34.5% for Class
B Shares, 34.5% for Class C Shares and 35.4% for Class O Shares. Total return
for the Fund including the effects of the maximum 4.75% front-end and any
applicable deferred sales charges was 28.9% for Class A Shares, 29.5% for Class
B Shares, 33.5% for Class C Shares and 35.4% for Class O Shares for the same
period. This compares with a total return of 37.5% for the twelve months ended
December 31, 1995 for the Standard and Poor's 500 Composite Stock Price Index
and a 30.8% average of 439 Growth and Income Funds tracked by Lipper Analytical
Services, Inc.

The Fund's under-performance, prior to the deduction of the applicable sales
charges, relative to the benchmark was due in part to the result of the Fund's
cash position. Our holdings in financial stocks performed well. Technology
holdings were pared to a below-market weight in the second quarter -- a
position that underperformed initially, but helped results in the last part of
the year. The Fund's position in retail stocks is divided between department
stores (Federated Department Stores and Sears, Roebuck) and food retailers
(Penn Traffic, Kroger, Stop & Shop Companies and Albertson's). Despite
the challenging consumer environment, department store stocks were strong
performers in 1995. In fact, Sears, Roebuck was the second best performing
stock in the Dow Jones Industrial Average Index for the year.

Portfolio Review (concluded)

With the chance of earnings disappointments increasing in a slowing economy,
the Fund is emphasizing companies with less cyclical exposure and more
predictable earnings growth. SmithKline Beecham-ADR, First Data and The Bank of
New York are among the Fund's top ten holdings. We consider companies that are
restructuring such as Ball, Federated Department Stores and Sears, Roebuck to
be defensive holdings in a decelerating economy since they are less dependent
on top line growth to achieve their earnings estimates. In addition, we
have added holdings of companies with middle-size capitalizations ($500 million
to $5 billion) to the Fund's portfolio over the past several months. These
companies typically have less overseas exposure than larger firms, and thus
these holdings should help insulate the portfolio from potential negative
effects of decelerating European markets and the impact of a stronger dollar.

NOTES TO FINANCIAL STATEMENTS
 
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 operates as a
series company comprised of nine 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 U.S.
Treasury Securities Money Market Fund (the "U.S. Treasury 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"), and Salomon Brothers Total Return Fund (the "Total Return Fund").
Separate financial statements are prepared for the New York Municipal Money Fund
and U.S. Treasury 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 achieve a high level of current income which is exempt
from regular federal income taxes; the U.S. Government Income Fund's objective
is to obtain a high level of current income; the High Yield Bond Fund's
objective is to maximize current income; the Strategic Bond Fund's objective is
to seek a high level of current income; the Total Return Fund's objective is to
obtain above-average income (compared to a portfolio entirely invested in equity
securities); the 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
commenced
 
                                                                         PAGE 41

</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.
 
          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.
 
PAGE 42
<PAGE>   44
 
SALOMON  BROTHERS  INVESTMENT  SERIES
 

 
          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 will be 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 and Investors Fund may enter into futures contracts for
     hedging purposes, 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 and the Strategic
     Bond 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 period ended December 31,
     1995 was approximately $2,150,000 and $1,052,000 for the U.S. Government
     Income Fund and the Strategic Bond 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 and Investors
 
                                                                         PAGE 43

SALOMON  BROTHERS  INVESTMENT  SERIES

NOTES TO FINANCIAL STATEMENTS
 
     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 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 December 31,
     1995 were $336,250 each.
 
          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 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 for each of the Funds (except the Investors Fund) are
     declared each business day to shareholders of record that day, and are paid
     on the last business
 
PAGE 44
<PAGE>   46
 
SALOMON  BROTHERS  INVESTMENT  SERIES
 


 
     day of the month. 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 and 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.
 
          (N) 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 U.S. Government Income Fund and Strategic
     Bond 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 Salomon Inc, to
act as investment manager, subject to the supervision by the Board of Directors
of each Fund. SBAM furnishes each Fund in the Investment Series with office
space and certain
 
                                                                         PAGE 45

NOTES TO FINANCIAL STATEMENTS
 
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, and .55%
for the Total Return 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.
 
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:

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. The first performance adjustment
reducing the management fee by $267,836 was made on September 30, 1995,
representing a seven percent higher performance by the S&P 500 Index for the
period from October 1, 1994 through September 30, 1995. An additional reduction
in the base management fee of $31,182 was recorded for the quarter ended
December 31, 1995, representing a three percent higher performance by the S&P
500 Index.
 
For the year ended December 31, 1995, SBAM waived management fees of $25,505,
$19,069, $44,953, $53,073, $79,385, $71,026 and $15,069 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 and Total
Return Fund, respectively, and voluntarily absorbed expenses of $75,716,

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 year
ending December 31, 1995.
 
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 year ended December 31, 1995,
credits earned on outstanding cash balances were used to reduce custodian fees
by $9, $1,758, $5,279, $21, $735, $208, $13 and $529 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 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 $210 and $95,179 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 December 31, 1995.
 
Salomon Brothers received $1,990 as its portion of the front-end sales charge on
sales of Class A shares of the Funds. In addition, contingent deferred sales
charges of $2,290 were paid to Salomon Brothers in connection with redemptions
of certain Class B and Class C shares of the Funds during the year ended
December 31, 1995.

During the year ended December 31, 1995, net realized loss from written option
transactions for the Investors Fund amounted to $268,953 and net realized loss
from purchased option transactions amounted to $113,136, for a net realized loss
on all option transactions for the Investors Fund of $382,089.
 
During the period ended December 31, 1995, net realized gain from forward
foreign currency contracts for the Strategic Bond Fund amounted to $67,840, and
net realized gains on mortgage dollar rolls amounted to $57,813 and $17,359 for
the U.S. Government Income Fund and the Strategic Bond Fund, respectively.
 
During the year ended December 31, 1995, permanent book/tax differences of
$(23,543) and $63 for the Strategic Bond Fund and Investors Fund, respectively,
arising primarily from foreign currency gains (losses) have been reclassified
from accumulated gain (loss) on investments to undistributed net investment
income. Net investment income, net realized losses and net assets were not
affected by this reclassification.
 
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 credit ratings are within the highest ratings
category of two nationally recognized statistical rating organizations
("NRSROs") or if rated by only one
 
                                                                         PAGE 51
<PAGE>   53
 
SALOMON  BROTHERS  INVESTMENT  SERIES
 
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
 
NRSRO, the highest rating of 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 the interest on which is exempt from regular federal income taxes
and at least 65% of its net assets in obligations the interest on which is
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 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.
 
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 covered call option is that the Fund may forego the
opportunity of profit if the market price of the underlying security increases
and the option is exercised. A risk in writing a put option is that the Fund may
incur a loss if the market price of the underlying security decreases and the
option is exercised. In addition, there is the risk that the Fund may not be
able to enter 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.

REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Boards of Directors and Shareholders of
 
Salomon Brothers Cash Management Fund
 
Salomon Brothers New York Municipal Bond Fund
 
Salomon Brothers National Intermediate Municipal Fund
 
Salomon Brothers U.S. Government Income Fund
 
Salomon Brothers High Yield Bond Fund
 
Salomon Brothers Strategic Bond Fund
 
Salomon Brothers Total Return Fund

In our opinion, the accompanying statements of assets and liabilities, including
the portfolios of investments, and the related statements of operations, of cash
flows (for Salomon Brothers U.S. Government Income Fund) and of changes in net
assets and the financial highlights present fairly, in all material respects,
the financial position of the Salomon Brothers Cash Management Fund, Salomon
Brothers New York Municipal Bond Fund, Salomon Brothers National Intermediate
Municipal Fund, Salomon Brothers U.S. Government Income Fund, Salomon Brothers
High Yield Bond Fund, Salomon Brothers Strategic Bond Fund, Salomon Brothers
Total Return Fund (seven of the portfolios constituting Salomon Brothers Series
Funds Inc) and Salomon Brothers Investors Fund Inc (hereafter referred to as the
"Funds") at December 31, 1995, the results of each of their operations, the cash
flows (for Salomon Brothers U.S. Government Income Fund), the changes in each of
their net assets and the financial highlights for the periods indicated, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Funds' management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with generally
accepted auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 1995 by
correspondence with the custodian and brokers and the application of alternative
auditing procedures where confirmations from brokers were not received, provide
a reasonable basis for the opinion expressed above.

*    Maximum sales charge for Class A shares is 4.75% of the public offering
     price. Class A shares bear ongoing 12b-1 service fees.

**   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 bear ongoing 12b-1
     distribution and service fees.

+    Commencement of investment operations was January 3, 1995 for Class A, B
     and C and February 1, 1993 for Class O shares, respectively.

Note:     The average annual total returns reflect investment of dividends
          and/or capital gains distributions in additional shares with and
          without the effect of the maximum sales charge (Class A) or
          contingent deferred sales charge (Class B and C). The average annual
          return for a period less than a year has not been annualized.

          The Fund offers Class O shares to the 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.

          During the periods shown above, the Fund's investment adviser waived
          fees and/or reimbursed certain expenses of the Fund, as shown in the
          preceding audited financial statements. Absent such waivers and/or
          reimbursements, the Fund's average annual returns would have been
          lower.

          The investment return and principal value of an investment in the
          Fund will fluctuate so that an investor's shares, when redeemed, may
          be worth more or less than their original cost.

*    Maximum sales charge for Class A shares is 4.75% of the public offering
     price. Class A shares bear ongoing 12b-1 service fees.

**   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 bear ongoing 12b-1
     distribution and service fees.

+    Commencement of investment operations was February 22, 1995 for Class A,
     B, C and O shares.

@    The Salomon Brothers Broad Investment Grade Index is valued at month-end
     only. As a result, while the Fund's total return calculations used in this
     comparison are for the period February 22, 1995 through December 31, 1995,
     the Index returns are for the period March 1, 1995 through December 31,
     1995.

Note:      The average annual total returns reflect investment of dividends
           and/or capital gains distributions in additional shares with and
           without the effect of the maximum sales charge (Class A) or
           contingent deferred sales charge (Class B and C). The average annual
           return for a period less than a year has not been annualized.

           The Fund offers Class O shares to the 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.

           During its fiscal year ended December 31, 1995, the Fund's
           investment adviser reimbursed certain expenses of the Fund, as shown
           in the preceding audited financial statements. Absent such
           reimbursements, the Fund's average annual returns would have been
           lower.

           The investment return and principal value of an investment in the
           Fund will fluctuate so that an investor's shares, when redeemed, may
           be worth more or less than their original cost.

                           SALOMON BROTHERS 
                           NEW YORK MUNICIPAL MONEY MARKET FUND
 
                           SALOMON BROTHERS
February 20, 1996          U.S. TREASURY SECURITIES MONEY MARKET FUND
 
To Our Shareholders:
 
WE ARE PLEASED to provide this annual report for the period ended December 31,
1995 for the Salomon Brothers New York Municipal Money Market Fund and the
Salomon Brothers U.S. Treasury Securities Money Market Fund.
 
ANNUALIZED YIELDS for the seven days ended February 15, 1996 were 3.04% for the
New York Municipal Money Market Fund and 4.28% for the U.S. Treasury Securities
Money Market Fund. For the same period, shareholders reinvesting their dividends
obtained compounded effective annualized yields for the Funds of 3.09% and
4.38%, respectively.
 
THE BOND MARKET experienced an impressive rally in 1995. The Salomon Brothers
Broad Investment Grade Bond Index increased 18.5% for the year. The rally was
supported by signs of economic deceleration and an overall shift in investor
sentiment that the Fed would remain under pressure to ease monetary policy by
lowering interest rates. Investor sentiment in the municipal bond market turned
sharply negative in the second quarter, when fears of a flat tax structure
surfaced. These concerns began to dissipate at the end of the year, and the
market has performed well since then.
 
GLOBAL ECONOMIC WEAKNESS continues to dominate our thinking. In the United
States, there has been ample confirmation of the uneven quality of the current
expansion. Job growth has slowed. Although housing starts have bounced back
somewhat, it will likely take a substantial drop in mortgage rates to trigger
any meaningful pickup in the months ahead. Despite weakness abroad, exports show
surprising vigor. The dollar's strengthening, however, could slow further growth
in that area. Although external demand for U.S. goods remains solid, domestic
demand is suffering as the economic expansion matures, consumer debt burdens
grow and income gains slow.
 
REINFORCED BY FISCAL restraint, these factors point to a period of slower growth
that will encourage further easing of monetary policy by the Federal Reserve. We
continue to look for an economic environment characterized by slow growth and
low inflation.

                   SPECIAL NOTICE TO OUR SHAREHOLDERS OF THE
                   U.S. TREASURY SECURITIES MONEY MARKET FUND
 
We are pleased to inform you that the Board of Directors of Salomon Brothers
Series Funds Inc has approved changes for the Salomon Brothers U.S. Treasury
Securities Money Market Fund aimed at attracting new investors. The Board
believes that implementation of these changes will benefit all of the Fund's
shareholders and make the Fund a more attractive and valuable investment
opportunity. Specifically, as explained in the proxy statement being mailed to
shareholders, the Board has approved a proposal from the Funds' investment
manager, Salomon Brothers Asset Management Inc ("SBAM"), to restructure the Fund
as a general purpose, money market fund to be marketed primarily to
institutions. Under SBAM's proposal, all existing investors would continue to be
entitled to remain in the Fund and add to their investments.
 
In connection with this restructuring, through the proxy materials, shareholders
are being asked to approve an amendment to the Fund's investment objective, an
amendment to the Fund's investment limitations and an amendment to the
investment management contract with SBAM to change the management fee from .10%
of average daily net assets to .20%. However, SBAM will impose a voluntary cap
on the total expenses of the Fund at .18% of average daily net assets for at
least the next year, and at no more than .25% thereafter. For the year ended
December 31, 1995, the expense ratio was .65%. Therefore, the expense ratio of
the Fund will decline substantially from its current rate.
 
I ENCOURAGE YOU TO REVIEW THE DETAILS ON THE PROPOSED AMENDMENTS COVERED IN THE
PROXY STATEMENT. PLEASE CALL US AT 1-800-SALOMON (1-800-725-6666) WITH ANY
QUESTIONS.

SALOMON BROTHERS MONEY MARKET FUNDS

NOTES TO FINANCIAL STATEMENTS
 
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 nine 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 U.S. Treasury Securities Money Market Fund (the "U.S. Treasury 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"), and Salomon Brothers Total Return Fund (the "Total Return Fund"). The
New York Municipal Money Fund and the U.S. Treasury Fund (individually, a
"Fund", collectively, the "Funds") are included in this report. The New York
Municipal Money 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 U.S. Treasury
Fund's objective is to seek a high level of current income by investing only in
short-term United States government and government agency securities. 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,
and Total Return Fund are reported in a separate report and are not included
herein.
 
Following is a summary of significant accounting policies followed by each 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.  Each 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.

<PAGE>   92
 
SALOMON BROTHERS MONEY MARKET FUNDS
 
- --------------------------------------------------------------------------------
 
          (C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends on the
     shares of each Fund are declared each business day to shareholders of
     record 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 that incurred
     them, and general expenses of the Company are allocated to the Funds 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 each
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 the following annual percentages of the Funds' average daily net
assets: .20% for the New York Municipal Money Fund and .10% for the U.S.
Treasury Fund. For the year ended December 31, 1995, SBAM voluntarily waived
management fees of $31,455 and $7,096 for the New York Municipal Money Fund and
U.S. Treasury 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 year
ended December 31, 1995.
 
                                                                         PAGE 15

NOTES TO FINANCIAL STATEMENTS
 
The U.S. Treasury Fund incurred realized losses on the sale of certain
securities in current and previous years. In order to maintain a $1 net asset
value per share, SBAM contributed $48,447 to offset cumulative net realized
losses. For tax purposes, this contribution was applied against the realized
losses for the year ended December 31, 1995. Accordingly, such amount has been
reclassified from paid-in-capital to accumulated net realized loss on
investments in the composition of net assets detailed in Note 3.
 
Investors Bank & Trust Company serves as custodian and administrator for each
Fund, which includes performing custodial and certain administrative services in
connection with the operation of each Fund. During the year ended December 31,
1995, custodian fees were reduced by $6,021 and $31 for the New York Municipal
Money Fund and U.S. Treasury Fund, respectively, relating to credits earned on
cash balances held by the custodian.
 
Each Fund has an agreement with Salomon Brothers Inc to distribute its shares.
 
3. CAPITAL STOCK
 
At December 31, 1995, the Company had 10,000,000,000 shares of authorized
capital stock, par value $.001 per share, of which the New York Municipal Money
Fund and the U.S. Treasury Fund each had 1,111,111,112 shares authorized.
 
Net assets, after re-classification of book/tax differences, consist of:

4. PORTFOLIO ACTIVITY
 
The New York Municipal Money Fund invests in money market instruments maturing
in thirteen months or less whose credit ratings are within the highest ratings
category of two nationally recognized statistical rating organizations
("NRSROs") or if rated by only one NRSRO, the highest rating of that NRSRO, or,
if not rated, are believed by the investment manager to be of comparable
quality. The U.S. Treasury Fund invests in U.S. Treasury Securities maturing in
thirteen months or less. The New York Municipal Money Fund pursues its
investment objectives by investing at least 65% of its net assets in obligations
that are exempt from regular Federal income tax and 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.
 
During the year ended December 31, 1995, the New York Municipal Money Fund and
U.S. Treasury Fund utilized $27,604 and $6,411, respectively, of capital loss
carry-forwards to offset net realized capital gains. At December 31, 1995, the
Funds had net capital loss carry-forwards available to offset future capital
gains as follows:

REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Salomon Brothers New York Municipal Money Market Fund and
Salomon Brothers U.S. Treasury Securities Money Market Fund
 
In our opinion, the accompanying statements of assets and liabilities, including
the portfolios of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Salomon Brothers New York Municipal
Money Market Fund and Salomon Brothers U.S. Treasury Securities Money Market
Fund (two of the portfolios constituting Salomon Brothers Series Funds Inc,
hereafter referred to as the "Funds") at December 31, 1995, the results of each
of their operations for the year then ended, the changes in each of their net
assets for each of the two years in the period then ended and the financial
highlights for each of the periods indicated, in conformity with generally
accepted accounting principles. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Funds' management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 1995 by
correspondence with the custodian, provide a reasonable basis for the opinion
expressed above.
