Dear Shareholder:

We are pleased to provide the semi-annual report for the Travelers Series Fund
Inc. -- Smith Barney International Equity, Smith Barney Pacific Basin and GT
Global Strategic Income Portfolios ("Portfolios") for the period ended April 30,
1998. For your convenience, we have summarized the period's prevailing economic
and market conditions and outlined each Portfolio's investment strategy. A
detailed summary of performance and current holdings can be found in the
appropriate sections that follow.

Portfolio Highlights
Smith Barney International Equity Portfolio

For the six months ended April 30, 1998, the Smith Barney International Equity
Portfolio provided a total return of 12.17%. The MSCI EAFE Index had a return of
15.59% over the same period. (The Morgan Stanley Capital International ("MSCI")
EAFE Index is a composite portfolio consisting of equity total returns for the
countries of Europe, Australia, New Zealand and countries in the Far East.)

For much of the past three years the portfolio managers have materially
overweighted European stocks in the Portfolio, both in large and
mid-capitalization growth stocks. The strength of the U.S. dollar considerably
reduced unhedged returns in 1997, while the large capitalization stock market
bias so evident in the U.S. also caused large capitalization international
stocks to outperform smaller stocks. The Portfolio's emerging market (i.e.,
non-EAFE) exposure also did not contribute to returns during the year as the
emerging markets materially underperformed the developed markets.

The managers pursue a "bottom-up" approach to stock investing -- namely, they
look for promising companies and industries rather than trying to discover
investment opportunities based on the present or future condition of the global
economy, the financial markets or the performance of particular markets. They
seek companies growing at a faster rate to that of their local country. At the
same time, they strive to maintain a risk level no higher than that of the
overall international stock market through broad diversification in a variety of
markets.

In their view, three trends predominated in the international stock markets
during the latter stages of the reporting period:

     o    Large-capitalization stocks materially outperformed mid- and
          small-capitalization stocks.

     o    The stock markets of relatively mature, developed economies
          outperformed the more volatile and less liquid emerging markets.

     o    The strength of the U.S. dollar versus the currencies of the United
          States' major trading partners largely negated returns earned in local
          currencies.

The latter months of 1997 and early 1998 were marked by a sense of crisis in the
international markets. The Southeast Asian currency collapse radiated outward,
engulfing not only some of the strongest regional economies (such as Taiwan and
Singapore) but also ultimately crushing the Korean economy and its currency. In
Japan, the largest Asian stock market and economy and a major regional lender,
the crisis contributed to an already deteriorating local Japanese outlook.

The portfolio managers believe the Asian currency and economic collapse has
far-reaching and as yet not fully understood implications for global capital
markets. So far, rescue efforts have centered on creating stability and stemming
further precipitous declines in currencies and consumer and business confidence,
such as the feverish year-end efforts of the International Monetary Fund ("IMF")
and global banks to prevent a total collapse of the Korean financial system. In
light of this turmoil, the strength of the U.S. dollar and bond market, to some
degree, has reflected investor preferences for liquidity, stability and
strength.

But the intermediate effects of these financial woes on Asia cannot be denied:
economic contraction and decline, massive bankruptcies and debt restructurings
and reschedulings, potential labor and civil unrest, have all resulted in an
investment climate of much greater risk. Whether government and business policy
makers have the will and flexibility to make the correct rehabilitative choices
remains unanswerable and the managers believe another six to twelve months of
uncertainty in Asia appears very likely.

Moreover, European and U.S. companies may not escape untouched as their exports
to Asia decline. Furthermore, competitive Asian-produced goods are likely to
flood domestic markets now that prices (in U.S. dollars) have declined
substantially. While many U.S. companies have already used the Asian weakness as
an explanation for earnings shortfalls from consensus expectations in recent
reporting periods, the severity of the downturn should really be felt in 1998.

Yet, despite the number of bearish influences at work on the non-U.S. markets in
the past six months, there continue to be many positive developments such as:

     o    The push for European monetary union has created favorable
          macroeconomic conditions, the likes of which have not been seen for
          two decades. Interest rates and inflation are and likely will remain
          subdued, thus heightening demand for stocks from individuals and
          institutions. Eleven countries have successfully reformed their
          economies and qualified for the first round selections under the
          European Monetary Union ("EMU").

     o    Corporations in Europe are restructuring with great relish, boosting
          investor returns and for the first time aligning management interests
          with external shareholder interests through equity incentives.

     o    The strengthening of the U.S. dollar against its major trading
          partners of the past 30 months has improved export competitiveness for
          many major European and Asian exporters and led to an upturn in the
          consolidated European economy.

     o    Restructuring of many industries continues (such as in financial
          services and pharmaceuticals), as well as improving economies of scale
          and eliminating inefficient local and regional goods and service
          providers. At the same time, innovative mid-size companies are finding
          access to capital and an open door to technologies and processes that
          lower costs for businesses and consumers.

Smith Barney Pacific Basin Portfolio

For the six months ended April 30, 1998, the Smith Barney Pacific Basin
Portfolio generated a total return of -7.21%. The Portfolio's total return
exceeded its Lipper Analytical Services Inc. fund peer group average of -8.90%
over the same period, making the Portfolio one of the best performing funds in
its class.

Asian markets (excluding Japan) rebounded sharply during the second quarter,
helping the Portfolio to catch up with its benchmark -- the MSCI All Country
Asia Pacific Index. The portfolio managers believe the worst of the financial
meltdown in Asia is over and that adjustments currently underway will lead to
economic recovery for most countries over the next 12-18 months. (The MSCI All
Country Asia Pacific Index, comprising equities in Australia, New Zealand, Japan
and the Far East, is a common benchmark against which the performance of Asian
funds is measured.)

After suffering a free-fall during the second half of 1997, Asian stock prices
continued to slide in January but finally hit bottom in February and rebounded
sharply. This rebound, while good news for battered Asian investors, was not so
much an indication of bright prospects for Asian economies as it was a relief
rally that the worst may be over. Positive political and economic developments
continued into March, and investors felt comfortable buying oversold Asian blue
chip companies.

Several events triggered the turnaround in market sentiment. First, initiatives
taken by the Korean and Thai governments in conjunction with the IMF brought
hope that necessary structural reforms would finally begin. The announcement of
the Korean bank deal in late January was an especially important signal. (The
Korean government announced that it agreed to guarantee the loans of local banks
and issue bonds, in exchange for foreign commercial banks agreeing to rollover
short-term loans to the banking system). Another important but less publicized
factor was China's decision not to devalue the renmenbi, easing fears of another
round of damaging currency falls in the region. Finally, the lack of runaway
inflation had a stabilizing effect, reducing the need for high interest rates
and keeping currencies at attractive levels in real terms.

The Japanese stock market was out of sync with the rest of Asia, rising 12% in
U.S. dollar terms during January while regional markets fell. Investors were
hopeful that the thirty trillion yen financial package (about $250-$300 billion
dollars) proposed by the government, to provide better support for depositors,
shore-up the banking system and ease capital adequacy controls, would finally
get the Japanese economy back on track. However, government unwillingness to
combine this package with tax cuts, deregulation and financial restructuring,
tarnished the long-term outlook for growth in the Japanese economy, and caused
investors to lose confidence. The stock market was flat in February and fell by
7% in March, just when the rest of Asia was rallying strongly.

The managers believe that the worst of Asia's crisis is probably over but the
pain of adjustment is only beginning to be felt. Recessions are unfolding across
Asia, with Indonesia (1998 GDP estimated to decline by 10%), Korea and Thailand
(projected -4% GDP declines each) hit the hardest by last years' contagion.
Malaysia, despite government efforts, is now expected to fall into recession and
the Philippines is struggling to maintain growth at just above zero. Hong Kong
and Singapore will be hit harder than expected, affected by the sharp slowdown
in neighboring countries, and China will not meet its 8% growth target.
Australia and New Zealand escaped the financial turmoil suffered by regional
neighbors, but their growth prospects will be undermined by slower trade.

The short-term outlook for Japan is also poor, with the economy increasingly
looking like it's headed into recession. Japan's long period of economic
stagnation and recent ineffective attempts at boosting the economy indicate that
a sustained recovery cannot be achieved without deep structural and, especially,
financial reform. This requires strong political will and the ability to suffer
through painful reforms in order to emerge with a clean, efficient and
reinvigorated economy. The Japanese government has preferred to maintain the
status quo, using low interest rates and other funds to stave off a meltdown,
but this has not solved the country's structural problems. This has important

implications for the rest of Asia. First, a weak Japanese economy and yen pose a
double threat to Asian economies, since Japan is a major export destination as
well as the home of competitors and investors. Second, other countries would do
well to avoid the Japanese model and grasp the thorny nettles of reform as the
best way out of recession. Indeed, they will need to show progress in real
reform in order to attract the capital required for restructuring.

The portfolio managers expect most countries in Asia to suffer recession, or at
best slow growth, in 1998 as policy makers and corporations struggle through the
reform process. However, they are optimistic that these reform efforts will be
successful, and they look for growth in many countries to resume in the period
of 1999 through 2000. Going forward, we expect Asian stocks to perform strongly
next year.

First, while they remain skeptical of the Japanese government's efforts to
stimulate the economy, they find the Japanese stock market relatively less
volatile than other markets in the region at this time. Accordingly, the
managers have increased our exposure in select high quality Japanese companies.

Second, they believe that currency devaluations have made Asian products very
competitive in world markets and they expect exporters to thrive in the current
environment. In connection with this viewpoint, they have built positions in
selected exporters that are trading at very attractive levels currently and that
they expect can grow earnings by 15%-20% over the next few years.

Third, they are optimistic about the prospects for recovery in those countries
where governments are implementing reforms aggressively and working closely with
the IMF, including Thailand and Korea. At the same time, the managers are uneasy
with those countries where governments are resisting change and fighting with
the IMF, including Indonesia and Malaysia.

Fourth, the Pacific Basin is home to many world-class blue chip companies that
will survive the crisis and likely will emerge stronger as a result. However, it
is unrealistic to expect much in the way of performance from these companies
during 1998, as higher costs and slower economic growth will cause short-term
problems. The portfolio managers believe such companies will benefit in the long
run as they buy and consolidate weaker competitors, and that their shares should
be accumulated gradually. In the meantime, they have trimmed back holdings in
both Hong Kong and Singapore-based blue chips.

GT Global Strategic Income Portfolio

The investment objectives of the GT Global Strategic Income Portfolio are
primarily to seek high current income and secondarily to seek capital
appreciation. For the six months ended April 30, 1998, the Portfolio returned
5.43%, and


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

outperformed its Lipper Analytical Services Inc. peer group average of 3.84%
over the same period.

As you know, global and emerging market investing presents certain risks,
including risks related to currency fluctuations and political, economic and
social changes. In addition, investing in emerging market debt instruments
involves special considerations including the risk of default. These risks may
decrease the value of securities held by the Portfolio. The Portfolio may also
invest up to 50% of its total assets in debt securities rated below investment
grade. Such investments are speculative and involve a high degree of risk,
including the risk of default, and generally have more volatile prices than
higher quality securities.

After the first quarter of 1998, the portfolio managers outlook for bond markets
continues to be positive. Although the U.S. bond market may not surpass its
historic lows, the managers believe it is unlikely to reverse significantly, as
fundamentals remain positive. In Europe, they believe bonds will continue to
outperform in the near term as strong fundamentals argue for sustained lower
yields. While the portfolio managers believe that emerging bonds represent
reasonable value, they do recognize that political setbacks or adverse
developments in Eastern Asian financial markets could have an adverse impact.
They are, therefore, investing cautiously and selectively.

In closing, thank you for investing in the Smith Barney International Equity,
Smith Barney Pacific Basin and G.T. Global Strategic Income Portfolios. We look
forward to continuing to help you pursue your financial goals.

Sincerely,

     International Equity Portfolio on June 16, 1994 (commencement of
     operations), assuming reinvestment of dividends and capital gains, if any,
     at net asset value through April 30, 1998. The Morgan Stanley Capital
     International ("MSCI") EAFE-GDP Weighted Index and the MSCI EAFE Index are
     composite portfolios consisting of equity total returns for the countries
     of Europe, Australia, New Zealand and the Far East. The MSCI EAFE-GDP
     Weighted Index is weighted based on each country's Gross Domestic Product
     and the MSCI EAFE Index is weighted based on each company's market
     capitalization. The indices are unmanaged and are not subject to the same
     management and trading expenses of a mutual fund.

     All figures represent past performance and are not a guarantee of future
     results. Investment returns and principal value will fluctuate, and
     redemption value may be more or less than the original cost.

++   It is the opinion of management that the MSCI EAFE Index is a more
     appropriate broad-based benchmark for the market in which the Portfolio
     invests than the MSCI EAFE-GDP Weighted Index. In future reporting, the
     MSCI EAFE Index will be used as a basis of comparison of total return
     performance rather than the MSCI EAFE-GDP Weighted Index.

1. Significant Accounting Policies

The Smith Barney International Equity, Smith Barney Pacific Basin and GT Global
Strategic Income Portfolios ("Portfolio(s)") are separate investment portfolios
of the Travelers Series Fund Inc. ("Fund"). The Fund, a Maryland corporation, is
registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company and consists of these
Portfolios and ten other separate investment portfolios: AIM Capital
Appreciation, Alliance Growth, MFS Total Return, Putnam Diversified Income,
Smith Barney High Income, Smith Barney Large Cap Value (formerly known as Smith
Barney Income and Growth Portfolio), Smith Barney Money Market, Smith Barney
Large Capitalization Growth, TBC Managed Income and Van Kampen American Capital
Enterprise Portfolios. Shares of the Fund are offered only to insurance company
separate accounts which fund certain variable annuity and variable life
insurance contracts. The financial statements and financial highlights for the
other portfolios are presented in separate semi-annual reports.

The significant accounting policies consistently followed by the Portfolios are:
(a) security transactions are accounted for on trade date; (b) securities traded
on national securities markets are valued at the closing prices in the primary
exchange on which they are traded; securities listed or traded on certain
foreign exchanges or other markets whose operations are similar to the U.S.
over-the-counter market (including securities listed on exchanges where the
primary market is believed to be over-the-counter) and listed securities for
which no sales price was reported on that date are valued at the mean between
the bid and asked prices. Securities which are listed or traded on more than one
exchange or market are valued at the quotations on the exchange or market
determined to be the primary market for such securities; (c) securities maturing
within 60 days are valued at cost plus accreted discount or minus amortized
premium, which approximates value; (d) gains or losses on the sale of securities
are calculated by using the specific identification method; (e) interest income,
adjusted for amortization of premium and accretion of discount, is recorded on
an accrual basis; (f) dividend income is recorded on the ex-dividend date;
foreign dividends are recorded on the ex-dividend date or as soon as practical
after the Portfolios determine the existence of a dividend declaration after
exercising reasonable due diligence; (g) dividends and distributions to
shareholders are recorded on the ex-dividend date; (h) the accounting records of
the Portfolios are maintained in U.S. dollars. All assets and liabilities
denominated in foreign currencies are translated into U.S. dollars based on the
rate of exchange of such currencies against U.S. dollars on the date of
valuation. Purchases and sales of securities and income and expenses are
translated at the rate of exchange quoted on the respective date that such
transactions are recorded. Differences between income or expense amounts
recorded and collected or paid are adjusted when reported by

the custodian; (i) the character of income and gains to be distributed are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles. At October 31, 1997, reclassifications
were made to the capital accounts of Smith Barney International Equity Portfolio
to reflect permanent book/tax differences and income and gains available for
distribution under income tax regulations. Accordingly, a portion of net
investment loss amounting to $51,682 was reclassified to paid-in capital. Net
investment income, net realized gains and net assets were not affected by this
change; (j) each Portfolio intends to comply with the requirements of the
Internal Revenue Code of 1986, as amended pertaining to regulated investment
companies and make distributions of taxable income sufficient to relieve it from
substantially all Federal income and excise taxes; and (k) estimates and
assumptions are required to be made regarding assets, liabilities and changes in
net assets resulting from operations when financial statements are prepared.
Changes in the economic environment, financial markets and any other parameters
used in determining these estimates could cause actual results to differ.

In addition, the Portfolios may enter into forward exchange contracts in order
to hedge against foreign currency risk. These contracts are marked to market
daily, by recognizing the difference between the contract exchange rate and the
current market rate as an unrealized gain or loss. Realized gains or losses are
recognized when contracts are settled.

2. Management Agreement and Transactions with Affiliated Persons

Mutual Management Corp. ("MMC"), formerly known as Smith Barney Mutual Funds
Management Inc., a subsidiary of Salomon Smith Barney Holdings Inc. ("SSBH"),
acts as investment manager of the Smith Barney International Equity ("SBIE") and
the Smith Barney Pacific Basin ("SBPB") Portfolios. Travelers Investment
Adviser, Inc., ("TIA"), an affiliate of MMC, acts as the investment manager of
the GT Global Strategic Income Portfolio ("GTGSI"). SBIE and SBPB pay MMC a
management fee calculated at the annual rate of 0.90% of the average daily net
assets of each Portfolio, respectively. GTGSI pays TIA a management fee
calculated at an annual rate of 0.80% of its average daily net assets. These
fees are calculated daily and paid monthly.

TIA has entered into a subadvisory agreement with Chancellor LGT Asset
Management, Inc. ("LGT"). Pursuant to the subadvisory agreement, LGT is
responsible for the day-to-day portfolio operations and investment decisions for
GTGSI and is compensated for such services. TIA pays LGT a monthly fee
calculated at the annual rate of 0.375% of the average daily net assets of
GTGSI.

TIA has entered into a sub-administrative services agreement with MMC. TIA pays
MMC, as sub-administrator, a fee calculated at an annual rate of 0.10% of the
Portfolios' average daily net assets.

Smith Barney Inc. ("SB"), another subsidiary of SSBH, acts as distributor of
Fund shares. SB also acts as broker for certain portfolio transactions. For the
six months ended April 30, 1998, SB received no brokerage commissions.

All officers and one Director of the Fund are employees of SB.

4. Capital Loss Carryforward

At October 31, 1997, the Fund had capital loss carryforwards available to offset
future realized capital gains, if any, for Federal income tax purposes of
approximately $3,572,000 and $2,306,000 for SBIE and SBPB, respectively. To the
extent that these carryforward losses are used to offset capital gains, it is
probable that the gains so offset will not be distributed. The amounts and
expiration of the carryforward losses are indicated below. Expiration occurs on
October 31 of the year indicated.

6. Futures Contracts

Initial margin deposits are made upon entering into futures contracts and are
recognized as assets. Securities equal to the initial margin amount are
segregated by the custodian in the name of the broker. Additional securities are
also segregated up to the current market value of the futures contracts. During
the period the futures contract is open, changes in the value of the contract
are recognized as unrealized gains or losses by "marking to market" on a daily
basis to reflect the market value of the contract at the end of each day's
trading. Variation margin payments are received or made and recognized as assets
due from or liabilities due to broker, depending upon whether unrealized gains
or losses are incurred. When the contract is closed, the Portfolios record a
realized gain or loss equal to the difference between the proceeds from (or cost
of) the closing transactions and the Portfolios' basis in the contract.

The Portfolios enter into such contracts to hedge a portion of their portfolios.
The Portfolios bear the market risk that arises from changes in the value of the
financial instruments and securities indices (futures contracts).

At April 30, 1998, the Portfolios had no open futures contracts.

7. Option Contracts

Premiums paid when put or call options are purchased by the Portfolios represent
investments, which are marked-to-market daily and are included in the schedules
of investments. When a purchased option expires, the Portfolios will realize a
loss in the amount of the premium paid. When the Portfolios enter into closing
sales transaction, the Portfolios will realize a gain or loss depending on
whether the proceeds from the closing sales transactions are greater or less
than the premium paid for the option. When the Portfolios exercise a put option,
they will realize a gain or loss from the sale of the underlying security and
the proceeds from such sale will be decreased by the premium originally paid.
When the

================================================================================

================================================================================

Portfolios exercise a call option, the cost of the security which the Portfolios
purchase upon exercise will be increased by the premium originally paid.

At April 30, 1998, the Portfolios did not hold any purchased call or put
options.

When the Portfolios write a covered call or put option, an amount equal to the
premium received by the Portfolios is recorded as a liability, the value of
which is marked-to-market daily. When a written option expires, the Portfolios
realize a gain equal to the amount of the premium received. When the Portfolios
enter into a closing purchase transaction, the Portfolios realize a gain or loss
depending upon whether the cost of the closing transaction is greater or less
than the premium originally received, without regard to any unrealized gain or
loss on the underlying security, and the liability related to such option is
eliminated. When a written call option is exercised, the cost of the security
sold will be decreased by the premium originally received. When a written put
option is exercised, the amount of the premium originally received will reduce
the cost of the security which the Portfolios purchased upon exercise. When
written index options are exercised, settlement is made in cash.

The risk associated with purchasing options is limited to the premium originally
paid. The Portfolios enter into options for hedging purposes. The risk in
writing a covered call option is that the Portfolios give up the opportunity to
participate in any increase in the price of the underlying security beyond the
exercise price. The risk in writing a put option is that the Portfolios are
exposed to the risk of loss if the market price of the underlying security
declines.

During the period ended April 30, 1998, the Portfolios did not write any
options.

8. Reverse Repurchase Agreement

GTGSI may enter into reverse repurchase agreement transactions for leveraging
purposes. A reverse repurchase agreement involves a sale by GTGSI of securities
that it holds with an agreement by GTGSI to repurchase the same securities at an
agreed upon price and date. A reverse repurchase agreement involves the risk
that the market value of the securities sold by GTGSI may decline below the
repurchase price of the securities. GTGSI will establish a segregated account
with its custodian, in which GTGSI will maintain cash, U.S. government
securities or other liquid high grade debt obligations equal in value to its
obligations with respect to reverse repurchase agreements.

At April 30, 1998, GTGSI had no open reverse repurchase agreements.

9. Lending of Portfolio Securities

The Portfolios have an agreement with their custodian whereby the custodian may
lend securities owned by the Portfolios to brokers, dealers and other financial
organizations. Fees earned by the Portfolios on securities lending are recorded
as interest income. Loans of securities by the Portfolios are collateralized by
cash, U.S. government securities or high quality money market instruments that
are maintained at all times in an amount at least equal to the current market
value of the loaned securities, plus a margin which may vary depending on the
type of securities loaned. The custodian establishes and maintains the
collateral in segregated accounts.

The Portfolios maintain exposure for the risk of any loss in the investment of
amounts received as collateral.

At April 30, 1998, the Portfolios listed below had loaned common stock. The
market value for the securities on loan for each portfolio was as follows:

10. Portfolio Concentration

The Portfolios' investments in foreign securities may involve risks not present
in domestic investments. Since securities may be denominated in a foreign
currency and may require settlement in foreign currencies and pay interest or
dividends in foreign currencies, changes in the relationship of these foreign
currencies to the U.S. dollar can significantly affect the value of the
investments and earnings of the Portfolios. Foreign investments may also subject
the Portfolios to foreign government exchange restrictions, expropriation,
taxation or other political, social or economic developments, all of which could
affect the market and/or credit risk of the investments.

In addition to the risks described above, risks may arise from forward foreign
currency contracts with respect to the potential inability of counter- parties
to meet the terms of their contracts.

11. Securities Traded on a To-Be-Announced Basis

SBIE and GTGSI may trade securities on a "to-be-announced" ("TBA") basis. In a
TBA transaction, the Portfolios commit to purchasing or selling securities for
which specific information is not yet known at the time of the trade,
particularly the face amount and maturity date in GNMA transactions. Securities
purchased on a TBA basis are not settled until they are delivered to the
Portfolios, normally 15 to 45 days later. These transactions are subject to
market fluctuations and their current value is determined in the same manner as
for other securities.

At April 30, 1998, the Portfolios did not hold any TBA securities.

12. Capital Shares

At April 30, 1998, the Fund had six billion shares of capital stock authorized
with a par value of $0.00001 per share. Each share of a Portfolio represents an
equal proportionate interest in that Portfolio with each share of the same
Portfolio and has an equal entitlement to any dividends and distributions made
by the Portfolio.

Transactions in shares of each Portfolio were as follows:

     Proposal 2 requested that shareholders approve certain changes to the
fundamental policies of the Portfolios in order to modernize them in view of
certain regulatory, business or industry developments that have occurred since
original adoption of these policies by the Portfolios. The following chart
demonstrates that all proposals were approved by shareholders.

     Please note that "M" indicates a modification of the policy; "E" indicates
the elimination of the policy; and "R" indicates the reclassification of the
policy from fundamental (which would require shareholder approval to change) to
non-fundamental (which can be changed by a vote of the Board of Directors).

Dear Shareholder:

We are pleased to provide the semi-annual report for the Travelers Series Fund
Inc. - Smith Barney High Income and Putnam Diversified Income Portfolios
("Portfolios") for the six months ended April 30, 1998. In this report, we
summarize the period's prevailing economic and market conditions and outline the
investment strategy employed by each Portfolio. A detailed summary of
performance and current holdings can be found in the appropriate sections that
follow.

Portfolio Highlights
Smith Barney High Income Portfolio

The Smith Barney High Income Portfolio seeks high current income. Capital
appreciation is a secondary objective. For the six months ended April 30, 1998,
the Smith Barney High Income Portfolio returned 5.21%. This return compares
favorably with its Lipper Analytical Services, Inc. ("Lipper") peer group
average of 3.65% for the same period. (Lipper is an independent fund-tracking
organization.)

The high yield bond market generated positive performance during the six months
ended April 30, 1998. In the first quarter of 1998, the high yield bond market
continued to generate competitive performance returns. The lower-quality issues
generally outperformed the higher-quality issues, as the performance of the
lower-quality issues tends to correlate more closely to the U.S. stock market.

During the first quarter of 1998, the U.S. stock market rose by 10% to 15%
depending upon which stock market index was used. A strong U.S. economy, ample
liquidity in the financial markets and moderate inflation continued to fuel the
stock markets. Interest rates remained confined to a narrow range with little
change in the rates of intermediate- and long-term U.S. Treasury securities. The
Federal Reserve Board ("Fed") continued to remain on the sidelines, and
short-term interest rates stayed unchanged at 5.50%.

While the Asian crisis did not dampen U.S. economic growth, it did keep pressure
on worldwide inflation with price declines on a number of important global
commodities such as oil. The net result was extremely positive for U.S.
financial markets, particularly the U.S. stock market. The U.S. bond market was
stuck in a narrow trading range and we believe the bond market will probably
continue to trade in a narrow range as long as the Fed's monetary policy remains
on hold. However, in recent weeks, the Fed has grown more concerned over strong
U.S. economic growth and the possibility that inflation may be increasing. Yet
the evidence so far suggests otherwise, with most statistics indicating
relatively tame inflation during the first quarter of 1998.

During the first three months of 1998, the stock markets exhibited high
volatility with most major indices again moving toward record highs. Despite
record new issuance, the high yield bond market also generated strong
performance results in the first quarter. In the view of the portfolio manager,
this was likely in reaction to the continued strength in the U.S. stock markets.

The manager continues to believe that the U.S. economy's outlook remains mixed
and that many consumer-sensitive industries will continue to experience fierce
price competition. In addition, the significant problems in Asia could also put
severe pressure on commodity goods prices as troubled Asian companies attempt to
increase their exports to the rest of the world to make up for the expected
economic declines in their own region. Moreover, the manager believes that a
slowdown in overall world economic growth may occur in the coming months as the
severe economic decline in Asia sharply reduces demand for many U.S. and
European products. Consequently, the first half of 1998 could experience a
slight increase in the default rates of select high yield credits, especially
weaker, more vulnerable companies that are having difficulty competing. Given
the increased uncertainty over Asia, the manager expects stock market volatility
to further rise in the coming months.

The portfolio manager will therefore still avoid these areas of the U.S. economy
where consumer spending is weak as well as industries facing heavy pricing
competition. His emphasis will be on industries that are experiencing strong
growth such as telecommunications, media and cable television. He also plans on
owning stronger rated B and BB bonds and avoiding the weaker, lower tier issues
that are generally in the CCC/Caa rating category. The portfolio manager
believes his investment strategy is a prudent course of action given the higher
risks and volatility he expects in the world's financial markets going forward.

Putnam Diversified Income Portfolio

As the Putnam Diversified Income Portfolio began its fiscal year last October,
Putnam was reasonably optimistic about prospects for fixed-income markets around
the world. Less than one month into the period, however, several Asian economies
experienced economic meltdowns, sparking the largest single-day point decline in
the history of the Dow Jones Industrial Average ("DJIA"). (The DJIA is a
price-weighted average of 30 actively traded blue chip stocks, primarily
industrials.) This event, combined with continued economic weakness and
uncertainty in Asia, put the world's financial markets, and investors' nerves,
on edge.

For the six months ending April 30, 1998, the Putnam Diversified Income
Portfolio returned 4.14%. This return compares favorably with its Lehman
Brothers Aggregate Bond Index, which posted a total return of 3.59% over the
same period. (The Lehman Brothers Aggregate Bond Index is an unmanaged index
composed of the Lehman Intermediate Government/Corporate Bond Index and the
Mortgage-Back Securities Index and includes U.S. Treasury issues, agency issues,
corporate bond issues and mortgage-backed securities.)

While this backdrop has created a tumultuous environment for many markets, two
of the three key sectors in which the Portfolio invests - U.S. taxable
investment-grade securities and high-yield bonds - actually fared quite well
during the reporting period. International bond markets obviously faced tougher
times, but strategic portfolio shifts allowed Putnam to soften the blow of
Asia's currency and debt crises. As of April 30, 1997, 37% of the Portfolio's
holdings were allocated to U.S. government and mortgage securities, 38% to
high-yield bonds, and 19% to international bonds.

Throughout the period, the Asian crisis actually boosted performance in the
domestic bond market. Nervous international investors flocked to the high credit
quality and attractive yields offered by U.S. bonds, bidding up the prices of
U.S. Treasurys dramatically. While this flight to quality was good news for the
Portfolio, Putnam's focus on mortgage-backed securities, which also performed
well early in the period, meant the Portfolio did not take full advantage of the
Treasury rally. Toward the end of the period, the momentum of Treasurys slowed,
while the performance of mortgage-backed securities began to lag as well.

Putnam's decision to focus on mortgage-backed securities was based on the
interest-rate climate during the period under review. When interest rates are
falling, mortgage-backed securities present a higher prepayment risk - that is,
the chance that homeowners will refinance or pay off their mortgage loans early,
which dampens the value of these securities. To compensate investors for this


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

prepayment risk, mortgage-backed securities generally carry a higher yield than
most other U.S. government issues. The Portfolio's emphasis on mortgage-backed
securities was designed to take advantage of those higher yield opportunities.

The Asian currency and debt crisis took its toll on many international markets,
hitting the emerging markets especially hard. As investors deserted these bonds
in favor of more established markets, emerging markets plunged in October,
although they posted handsome gains for most of calendar 1997. After that rather
brief swoon, however, these bonds staged a remarkable recovery. In a situation
similar to the U.S. Treasury rally, this rebound helped the Portfolio; but
because this portion of the Portfolio was positioned defensively, it did not
take full advantage of the emerging-markets comeback.

In Europe, bond markets turned in robust returns as a result of sluggish
economic growth in Germany and expectations that the European Economic and
Monetary Union ("EMU") would begin as scheduled in January 1999. (The EMU will
unify the monetary policy and interest rates of 11 European countries.) Europe's
peripheral markets, such as Spain, Italy and Sweden, posted the best
performance, but the Portfolio's underweight position in these areas dragged
performance somewhat. The Portfolio benefited from a significant position in the
United Kingdom, where the bond market was buoyed by slowing economic growth and
low inflation. Putnam's decision to underweight Japanese government bonds meant
the Portfolio had only minimal exposure to these bonds, which were hurt by the
country's troubled political and economic climate and increasing concerns about
the long-term health of its economy.

The high-yield bond market was the strongest-performing sector of the domestic
bond market in the first calendar quarter of 1998, propelled by the same forces
that pushed U.S. Treasury bonds and many stocks higher. These forces included
solid economic growth and low inflation, which kept the Fed from increasing
interest rates.

Leading the way among high-yield bond issues were companies in the
telecommunications, cable TV and broadcasting industries - following a pattern
that has prevailed for well over a year. New issuance in the high-yield bond
market has continued at a record-breaking pace, driven by favorable interest
rates, expanding businesses and strong investor demand. Another factor boosting
the high-yield bond market has been the tremendous amount of merger and
acquisition activity. Larger, more creditworthy companies that have completed
cost-cutting programs are buying smaller high-yield bond issuers in an effort to
further grow their businesses or add niche products. This consolidation trend
was evident in many industries, including consumer products, telecommunications
and cable TV.

Putnam generally believes that the U.S. economy, driven by consumer demand, is
poised for continued strong growth with relatively low inflation going forward.
As a result, Putnam expects that the demand for high-yield bonds will remain
strong in the months ahead as investor confidence remains high.

However, Putnam is more cautious about international bond markets and the
outlook for global economic growth. Valuations in most foreign markets appear
stretched, particularly after the global flight to quality that has driven bond
yields lower worldwide. Putnam will continue to monitor the Asian turbulence
closely, realizing that its impact may be greater than previously forecast. The
Portfolio's ability to invest across multiple fixed-income sectors should enable
Putnam to position the portfolio defensively while still taking advantage of
attractive income opportunities. (Of course, no guarantees can be made that this
strategy will ultimately be successful.)

In closing, thank you for your investment in the Travelers Series Fund Inc. -
Smith Barney High Income and Putnam Diversified Income Portfolios. We look
forward to continuing to help you pursue your financial goals.

Sincerely,

Bond Ratings (unaudited)
================================================================================

All ratings are by Standard & Poor's Ratings Services ("Standard & Poor's"),
except that those identified by an asterisk (*) are rated by Moody's Investors
Service Inc.("Moody's"). The definitions of the applicable rating symbols are
set forth below:

Standard & Poor's -- Ratings from "AA" to "CC" may be modified by the addition
of a plus (+) or minus (-) sign to show relative standings within the major
rating categories

AAA       -- Bonds rated "AAA" have the highest rating assigned by Standard &
             Poor's. Capacity to pay interest and repay principal is extremely
             strong.

AA        -- Bonds rated "AA" have a very strong capacity to pay interest and
             repay principal and differ from the highest rated issue only in a
             small degree.

A         -- Bonds rated "A" have a strong capacity to pay interest and repay
             principal although it is somewhat more susceptible to the adverse
             effects of changes in circumstances and economic conditions than
             bonds in higher rated categories.

BBB       -- Bonds rated "BBB" are regarded as having an adequate capacity to
             pay interest and repay principal. Whereas they normally exhibit
             adequate protection parameters, adverse economic conditions or
             changing circumstances are more likely to lead to a weakened
             capacity to pay interest and repay principal for bonds in this
             category than in higher rated categories.

BB, B,    -- Bonds rated "BB", "B", "CCC", and "CC" are regarded, on balance, as
CCC,         predominantly speculative with respect to capacity to pay interest 
and CC       and repay principal in accordance with the terms of the obligation.
             "BB" represents the lowest degree of speculation and "CC" the      
             highest degree of speculation. While such bonds will likely have   
             some quality and protective characteristics, these are outweighed  
             by large uncertainties or major risk exposures to adverse          
             conditions.                                                        
          
Moody's-- Numerical modifiers 1, 2, and 3 may be applied to each generic rating
from "Aa" to "Ca", where 1 is the highest and 3 the lowest rating within its
generic category.

Aaa       -- Bonds that are rated "Aaa" are judged to be of the best quality.
             They carry the smallest degree of investment risk and are generally
             referred to as "gilt edge." Interest payments are protected by a
             large or by an exceptionally stable margin and principal is secure.
             While the various protective elements are likely to change, such
             changes as can be visualized are most unlikely to impair the
             fundamentally strong position of such issues.

Aa        -- Bonds that are rated "Aa" are judged to be of high quality by all
             standards. Together with the "Aaa" group they comprise what are
             generally known as high grade bonds. They are rated lower than the
             best bonds because margins of protection may not be as large as in
             "Aaa" securities or fluctuation of protective elements may be of
             greater amplitude or there may be other elements present which make
             the long-term risks appear somewhat larger than in "Aaa"
             securities.

A         -- Bonds that are rated "A" possess many favorable investment
             attributes and are to be considered as upper medium grade which
             suggest a susceptibility to impairment some time in the future.

Baa       -- Bonds that are rated "Baa" are considered as medium grade
             obligations, i.e., they are neither highly protected nor poorly
             secured. Interest payments and principal security appear adequate
             for the present but certain protective elements may be lacking or
             may be characteristically unreliable over any great length of time.
             Such bonds lack outstanding investment characteristics and in fact
             have speculative characteristics as well.

Ba        -- Bonds that are rated "Ba" are judged to have speculative elements;
             their future cannot be considered as well-assured. Often the
             protection of interest and principal payments may be very moderate
             and thereby not well safeguarded during both good and bad times
             over the future. Uncertainty of position characterizes bonds in
             this class.

B         -- Bonds that are rated "B" generally lack characteristics of
             desirable investments. Assurance of interest and principal payments
             or of maintenance of other terms of the contract over any long
             period of time may be small.

Caa       -- Bonds that are rated "Caa" are of poor standing. These issues may
             be in default, or present elements of danger may exist with respect
             to principal or interest.

Ca        -- Bonds that are rated "Ca" represent obligations which are
             speculative in a high degree. Such issues are often in default or
             have other marked shortcomings.

NR        -- Indicates that the bond is not rated by Standard & Poor's or
             Moody's.

1.   Significant Accounting Policies

The Smith Barney High Income and Putnam Diversified Income Portfolios
("Portfolio(s)") are separate investment portfolios of the Travelers Series Fund
Inc. ("Fund"). The Fund, a Maryland corporation, is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company and consists of these Portfolios and eleven other
separate investment portfolios: AIM Capital Appreciation, Alliance Growth, Van
Kampen American Capital Enterprise, Smith Barney Large Cap Value (formerly Smith
Barney Income and Growth), Smith Barney International Equity, Smith Barney
Pacific Basin, TBC Managed Income, GT Global Strategic Income, MFS Total Return,
Smith Barney Money Market and Smith Barney Large Capitalization Growth
Portfolios. Shares of the Fund are offered only to insurance company separate
accounts which fund certain variable annuity and variable life insurance
contracts. The financial statements and financial highlights for the other
portfolios are presented in separate semi-annual reports.

The significant accounting policies consistently followed by the Portfolios are:
(a) security transactions are accounted for on trade date; (b) securities traded
on national securities markets are valued at the closing prices on such markets;
securities for which no sales price was reported and U.S. government agencies
and obligations are valued at the mean between the bid and ask prices; (c)
securities maturing within 60 days are valued at cost plus accreted discount, or
minus amortized premium, which approximates value; (d) dividend income is
recorded on the ex-dividend date; foreign dividends are recorded on the
ex-dividend date or as soon as practical after the Portfolio determines the
existence of a dividend declaration after exercising reasonable due diligence;
(e) interest income, adjusted for accretion of original issue discount, is
recorded on an accrual basis; (f) gains or losses on the sale of securities are
calculated by using the specific identification method; (g) dividends and
distributions to shareholders are recorded on the ex-dividend date; (h) the
accounting records of the Portfolios are maintained in U.S. dollars. All assets
and liabilities denominated in foreign currencies are translated into U.S.
dollars based on the rate of exchange of such currencies against U.S. dollars on
the date of valuation. Purchases and sales of securities, and income and
expenses are translated at the rate of exchange quoted on the respective date
that such transactions are recorded. Differences between income or expense
amounts recorded and collected or paid are adjusted when reported by the
custodian bank; (i) the character of income and gains to be distributed are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles. At October 31, 1997, reclassifications
were made to the Portfolios' capital accounts to reflect permanent book/tax
differences and income and gains available for distribution under income tax
regulations. Net investment

income, net realized gains and net assets were not affected by this change; (j)
the Portfolios intend to comply with the requirements of the Internal Revenue
Code of 1986, as amended, pertaining to regulated investment companies and to
make distributions of taxable income sufficient to relieve it from substantially
all Federal income and excise taxes; and (k) estimates and assumptions are
required to be made regarding assets, liabilities and changes in net assets
resulting from operations when financial statements are prepared. Changes in the
economic environment, financial markets and any other parameters used in
determining these estimates could cause actual results to differ.

In addition, Putnam Diversified Income and Smith Barney High Income Portfolios
may enter into foreign currency exchange contracts in order to hedge against
foreign currency risk. These contracts are marked-to-market daily, by
recognizing the difference between the contract exchange rate and the current
market rate as an unrealized gain or loss. Realized gains or losses are
recognized when contracts are settled or closed.

2.   Management Agreement and Transactions with Affiliated Persons

Mutual Management Corp. ("MMC"), formerly known as Smith Barney Mutual Funds
Management Inc., a subsidiary of Salomon Smith Barney Holdings Inc. ("SSBH"),
acts as the investment manager of the Smith Barney High Income Portfolio
("SBHI"). Travelers Investment Adviser, Inc. ("TIA"), an affiliate of MMC, acts
as the investment manager of the Putnam Diversified Income Portfolio ("PDIP").
SBHI pays MMC a management fee calculated at an annual rate of 0.60% of the
average daily net assets of the Portfolio. PDIP pays TIA a management fee
calculated at an annual rate of 0.75% of the average daily net assets of the
Portfolio. These fees are calculated daily and paid monthly.

TIA has entered into a sub-advisory agreement with Putnam Investment Management,
Inc. ("PIM"). Pursuant to the sub-advisory agreement, PIM is responsible for the
day-to-day portfolio operations and investment decisions for PDIP and is
compensated for such service at the annual rate of 0.35% of the average daily
net assets of PDIP. This fee is calculated daily and paid monthly.

TIA has entered into a Sub-Administrative Services Agreement with MMC. TIA pays
MMC, as sub-administrator, a fee calculated at an annual rate of 0.10% of the
average daily net assets of PDIP.

Smith Barney Inc. ("SB"), another subsidiary of SSBH, acts as distributor of
Fund shares.

All officers and one Director of the Fund are employees of SB.

===============================================================================
</TABLE>

4.   Option Contracts

Premiums paid when put or call options are purchased by the Portfolios,
represent investments, which are marked-to-market daily and are included in the
schedules of investments. When a purchased option expires, the Portfolios will
realize a loss in the amount of the premium paid. When the Portfolios enter into
closing sales transaction, the Portfolios will realize a gain or loss depending
on whether the proceeds from the closing sales transaction are greater or lesser
than the premium paid for the option. When the Portfolios exercise a put option,
they will realize a gain or loss from the sale of the underlying security and
the proceeds from such sale will be decreased by the premium originally paid.
When the Portfolios exercise a call option, the cost of the security which the
Portfolios purchase upon exercise will be increased by the premium originally
paid.

At April 30, 1998, there were no open purchased call options.

When the Portfolios write a covered call or put option, an amount equal to the
premium received by the Portfolios is recorded as a liability, the value of
which is marked-to-market daily. When a written option expires, the Portfolios
realize a gain. When the Portfolios enter into a closing purchase transaction,
the Portfolios realize a gain or loss depending upon whether the cost of the
closing transaction is greater or less than the premium originally received
without regard to any unrealized gain or loss on the underlying security, and
the liability related to such option is eliminated. When a written call option
is exercised, the cost of the security sold will be decreased by the premium
originally received. When a

================================================================================

written put option is exercised, the amount of the premium originally received
will reduce the cost of the security which the Portfolios purchased upon
exercise. When written index options are exercised, settlement is made in cash.

The risk associated with purchasing options is limited to the premium originally
paid. The Portfolios enter into options for hedging purposes. The risk in
writing a covered call option is that the Portfolios give up the opportunity to
participate in any increase in the price of the underlying security beyond the
exercise price. The risk in writing a put option is that the Portfolios are
exposed to the risk of loss if the market price of the underlying security
declines.

The following covered call option transactions occurred in PDIP during the six
months ended April 30, 1998:

There were no open covered call option written contracts as of April 30, 1998.

5.   Foreign Currency Exchange Contracts

At April 30, 1998, the Portfolios had open foreign currency exchange contracts
as described below. The Portfolios record realized gains or losses at the time
the forward contract is offset by entry into a closing transaction or settlement
of the contract. The Portfolios bear the market risk that arises from changes in
foreign currency exchange rates. The unrealized gain (loss) on the contracts is
reflected in the accompanying financial statements as follows:

6.   Repurchase Agreements

The Portfolios purchase (and their custodian takes possession of) U.S.
government securities from banks and securities dealers subject to agreements to
resell the securities to the sellers at a future date (generally, the next
business day) at an agreed-upon higher repurchase price. The Portfolios require
continual maintenance of the market value of the collateral in amounts at least
equal to the repurchase price.

7.   Futures Contracts

Initial margin deposits made upon entering into futures contracts are recognized
as assets. Securities equal to the initial margin amount are segregated by the
custodian in the name of the broker. Additional securities are also segregated
up to the current market value of the futures contracts. During the period the
futures contract is open, changes in the value of the contract are recognized as
unrealized

gains or losses by "marking to market" on a daily basis to reflect
the market value of the contract at the end of each day's trading. Variation
margin payments are received or made and recognized as assets due from or
liabilities due to broker, depending upon whether unrealized gains or losses are
incurred. When the contract is closed, the Portfolios record a realized gain or
loss equal to the difference between the proceeds from (or cost of) the closing
transactions and the Portfolio's basis in the contract. The Portfolios enter
into such contracts to hedge a portion of their portfolios. The Portfolios bear
the market risk that arises from changes in the value of the financial
instruments and securities indices (futures contracts).

At April 30, 1998, the PDIP had the following open futures contracts:

8.   Lending of Portfolio Securities

The Portfolios have an agreement with their custodian whereby the custodian may
lend securities owned by the Portfolios to brokers, dealers and other financial
organizations. Fees earned by the Portfolios on securities lending are recorded
as interest income. Loans of securities by the Portfolios are collateralized by
cash, U.S. government securities or high quality money market instruments that
are maintained at all times in an amount at least equal to the current market
value of the loaned securities, plus a margin which may vary between 2% and 5%
depending on the type of securities loaned. The custodian establishes and
maintains the collateral in segregated accounts. The Portfolios maintain
exposure for the risk of any losses in the investment of amounts received as
collateral.

At April 30, 1998, the Portfolios had no securities on loan.

9.   Securities Traded on a When-Issued or To-Be-Announced Basis

PDIP may trade securities on a when-issued basis or on a to-be-announced ("TBA")
basis.

In a when-issued transaction the securities are purchased or sold by the
Portfolio with payment and delivery taking place in the future in order to
secure what is considered to be an advantageous price and yield to the

================================================================================

Portfolio at the time of entering into the transaction. Purchasing such
securities involves the risk of loss if the value of the securities declines
prior to settlement.

In a TBA transaction, the Portfolio commits to purchasing or selling securities
for which specific information is not yet known at the time of the trade,
particularly the face amount and maturity date. Securities purchased on a TBA
basis are not settled until they are delivered to the Portfolio, normally 15 to
45 days later. These transactions are subject to market fluctuations and their
current value is determined in the same manner as for other portfolio
securities.

At April 30, 1998, PDIP held three TBA securities with a cost of $3,326,436.

10.  Capital Shares

At April 30, 1998, the Fund had six billion shares of $0.00001 par value capital
stock authorized. Each share of a Portfolio represents an equal proportionate
interest in that Portfolio with each share of the same Portfolio and has an
equal entitlement to any dividends and distributions made by the Portfolio.

Transactions in shares of each Portfolio were as follows:

     method, rather than the undistributed net investment income method, because
     it more accurately reflects the per share data for the period.

     reimbursed the Portfolio for $19,028 in expenses for the period ended
     October 31, 1994. If such fees were not waived and expenses not reimbursed,
     the per share effect on net investment income and the expense ratios would

Proposal 2 requested that shareholders approve certain changes to the
fundamental policies of the Portfolios in order to modernize them in view of
certain regulatory, business or industry developments that have occurred since
original adoption of these policies by the Portfolios. The following chart
demonstrates that all proposals were approved by shareholders. 

Please note that "M" indicates a modification of the policy; "E" indicates the
elimination of the policy; and "R" indicates the reclassification of the policy
from fundamental (which would require shareholder approval to change) to
non-fundamental (which can be changed by a vote of the Board of Directors).

Dear Shareholder:

We are pleased to provide the semi-annual report of the Travelers Series Fund
Inc. -- Smith Barney Large Cap Value Portfolio (formerly known as Smith Barney
Income and Growth Portfolio), Alliance Growth Portfolio and Van Kampen American
Capital Enterprise Portfolio ("Portfolios") for the six months ended April 30,
1998. In this report, we summarize the period's prevailing economic and market
conditions and outline each Portfolio's investment strategy. A detailed summary
of performance and current holdings for each Portfolio can be found in the
appropriate sections that follow.

Portfolio Highlights
Smith Barney Large Cap Value Fund

For the six months ended April 30, 1998, the Smith Barney Large Cap Value
Portfolio ("Portfolio") had a total return of 17.71% which compared favorably to
the total return of 17.34% for its Lipper Analytical Services, Inc. ("Lipper")
growth fund peer group average over the same period. (Lipper is a major
fund-tracking organization.)

The Portfolio's managers typically choose large-capitalization companies that
have an above-market dividend yield and are undervalued by the marketplace. The
managers look to find a fundamental improvement underway, such as a new product
or new management, the positive effect of which has not yet been reflected in
the stock price.

The managers were impressed by the coming together of several positive events
sustaining this bull market, notwithstanding the fact that by many traditional
yardsticks, valuations are obviously trending higher. Specifically, the economy
continues to sustain its momentum, which points to ongoing growth in corporate
profits. What had previously been perceived as the Asian crisis (which had been
predicted to lead to the inevitable unraveling of all of the world's global
economies) is now being welcomed, at least from the perspective of the U.S.,
almost as the salvation of what otherwise might have become an overheated
economy for the Federal Reserve Board ("Fed") regulators.

Currently the Fed is unsettling to bond and stock investors alike with
threatening overtures of raising rates. In fact, the inflation news remains
surprisingly positive. Indeed, the markets recently rallied strongly as the
Employment Cost Index, allegedly one of Fed Chairman Greenspan's favorite
indices, came in short of popular expectations. Meanwhile, the demographics of
demand from the aging baby boomers both in the U.S., (and now overseas) continue
to create a positive demand for stocks just as supply is being contained by a
lack of initial public offerings, relatively speaking. Although the managers are
sensitive to the potential for short-term concerns about rates that can unsettle
the stock market, they nevertheless believe that the fundamentals are powerful
enough to allow the market to continue to go up.

The managers continue to be fully invested in the Portfolio, as is their custom.
The Portfolio enjoys an approximate 43% yield pick-up to the Standard & Poor's
500 Index, which should help to cushion volatility in a more difficult
environment and meanwhile acts as an ongoing way to enhance return potential.

Alliance Growth Portfolio

For the six months ended April 30, 1998, the Alliance Growth Portfolio
("Portfolio") generated a total return of 18.88%, outperforming the total return
of 17.34% for its Lipper growth fund peer group average.

The Portfolio's fiscal year ended on October 31, 1997, just days after the sharp
sell-off and equally rapid rebound marking the collapse of a number of Asian
currencies and securities markets. After holding up somewhat better than the
averages during the decline, the Portfolio lagged well behind in the initial
stage of recovery that was concentrated in very large capitalization stocks.
Since the initial month of recovery, the Portfolio has generally performed well
relative to the averages as the market has broadened out and the environment has
been more favorable to its style of investing that stresses large- and mid-cap
stocks but underweights the very largest companies that are most heavily
represented in the popular averages.

The chaos in Asian markets and economies appears not to have had any lasting
negative effect on the U.S. market. Paradoxically, it may have even had a
favorable impact in that it removed, for at least a few months, any likelihood
that the Fed would move to raise interest rates. Economic overheating and
resultant higher interest rates were what many investors had feared most. With
the sudden weakness in Asia, a weaker economy seemed more likely. As the first
quarter of 1998 unfolded it offered an unusually favorable climate for stocks.
Corporate earnings continued to grow, unemployment moved to the lowest level in
years and, at the same time, inflation and interest rates moved lower.

It is of course possible that the months ahead may continue to provide a balmy
climate for the stock market. Relative to Asia and Europe, the U.S. is still
primarily a domestic economy. The impact of bank failures or corporate
insolvencies in Asia should also fall much more heavily on Japanese and European
organizations rather than on American institutions.

One risk is that this is as good as it can get. The managers think that perhaps
we have seen the maximum benefit of lower commodity prices and Fed forbearance.
Perhaps the U.S. economy will finally slow and corporate profits will weaken. If
not, perhaps the Fed will decide that it is time to cool things down. At the
risk of appearing to repeat the same cautions with a foolish degree of
consistency, the managers once again note that stock market returns have been
far above long-term norms for an unusually long period of time. They would not
be surprised to see the market become less of a one way street in the months
ahead. That said, they do not believe that there is great short-term risk in the
market. Weakness from here would probably once again provide a buying
opportunity.

The managers' greater concern is that a continuation of favorable conditions may
lead to speculative overoptimism with an inevitably painful result. A more
moderate result is of course possible, and perhaps even likely. Although they
expect more modest returns than those achieved in recent years, they view the
longer-term outlook for both the U.S. economy and stock market to be quite
favorable. They are not inclined to change the areas of emphasis that have
predominated for several years now. Financial services and technology still look
most promising and they continue to underweight the commodity cyclical areas of
the economy. The pace of consolidation in financial services has quickened led
by huge combinations. They expect this trend to continue. In the technology
sector, they have continued to move away from PC-oriented chip and box companies
and toward those more involved in networking and telecommunications. There are
clearly revolutionary changes going on in all of communications as digital
technologies replace traditional analog ones. Greater capacity at lower cost is
making possible new uses. Digital communications traffic is growing at an
accelerating rate. Changing technology and regulation are creating new winners
and losers. This is arguably the world's largest industry and also its fastest
growing. The managers think that companies such as WorldCom and Cisco will
continue to lead the way for some time to come.

Van Kampen American Capital Enterprise Portfolio

For the six months ended April 30, 1998, the Van Kampen American Capital
Enterprise Portfolio ("Portfolio") generated a total return of 19.31%, which
compares favorably to the total return of 17.34% for its Lipper growth fund peer
group average.

The Portfolio is managed with a consistent investment philosophy: to own
companies with positive future fundamentals at attractive current prices.
Although this philosophy may sound simplistic, the managers believe that the
best total return potential is usually achieved by a primary focus on
disciplined stock selection. In selecting stocks, the managers of the Portfolio
generally look for at least one of the following fundamental characteristics:

   o Consistent earnings growth
   o Accelerating earnings growth
   o Better-than expected fundamentals
   o An underlying change in a company, industry, or regulatory environment

As long as the original criteria for purchasing a particular stock hold true and
its value remains relatively attractive, the stock usually stays in the
Portfolio. Today, high valuations are prevalent throughout much of the stock
market, so the managers are monitoring stock prices even more closely than
usual. Despite these constraints, they have been able to identify many suitable
securities to own in the Portfolio.

Favorable market and economic conditions once again aided the Portfolio's
performance. The Portfolio had modest turnover during the reporting period, with
the most notable change being a decrease in its holdings in technology. In
February, the technology industry began to suffer from an excess of personal
computers. Manufacturers such as Compaq and IBM, which sell computers to
retailers and wholesalers for distribution, had to reduce production of new
computers until inventory supply becomes more balanced with demand.
Consequently, the manufacturers of semiconductors, which are a critical
component of computers, had to reduce production as well. The managers decreased
the Portfolio's holdings in personal computers and semiconductors during the
reporting period, although this situation appears to be on its way toward some
resolution. Computer software remains the Portfolio's largest concentration
within technology, as these stocks were less affected by inventory issues.

The Portfolio maintained a significant position in consumer distribution or
retail, which contributed to positive performance. The confluence of several
factors made this sector attractive. On one hand, the U.S. is experiencing low
unemployment and rising disposable incomes, which have historically been
favorable to retail sales. On the other hand, retail management has shown
greater discipline about issues such as pricing and expansion. While the
emergence of an economic boom/bust scenario could be crippling to retailers, the
managers believe the continued slow but steady growth of the economy supports
strong future fundamentals for this sector. The Portfolio includes substantial
positions in grocery stores, including Safeway and Kroger, as well as general
retailers such as Dayton Hudson, TJDX Companies, and Ross Stores.

At the time of the last report on October 31, 1997, the effects of the Asian
economic crisis were unclear but ominous. Today, its effects are still
uncertain, but the outlook is more positive. While the Asian crisis has had a
severe impact on a few segments of the U.S market, so far it appears to be
fairly contained. The stock market was reaching new highs at the end of the
reporting period, and the managers expect a continuation of controlled but
slowing economic growth and low inflation. They believe these conditions should
benefit the Portfolio, and the portfolio management team is optimistic about
adding value over the long-term based on their disciplined investment management
philosophy.

In closing, thank you for investing in the Travelers Series Fund Inc. - Smith
Barney Large Cap Value Portfolio, Alliance Growth Portfolio and Van Kampen
American Capital Enterprise Portfolio. We look forward to continuing to help you
pursue your financial goals.

Sincerely,


/s/ Heath B. Mclendon

1. Significant Accounting Policies

The Smith Barney Large Cap Value Portfolio (formerly known as Smith Barney
Income and Growth Portfolio), Alliance Growth Portfolio and Van Kampen American
Capital Enterprise Portfolio ("Portfolio(s)") are separate investment portfolios
of the Travelers Series Fund Inc. ("Fund"). The Fund, a Maryland corporation, is
registered under the Investment Company Act of 1940, as amended, as an open-end
management investment company and consists of these Portfolios and ten other
separate investment portfolios: AIM Capital Appreciation, Smith Barney
International Equity, Smith Barney Pacific Basin, TBC Managed Income, Putnam
Diversified Income, GT Global Strategic Income, Smith Barney High Income, MFS
Total Return, Smith Barney Large Capitalization Growth and Smith Barney Money
Market Portfolios. Shares of the Fund are offered only to insurance company
separate accounts which fund certain variable annuity and variable life
insurance contracts. The financial statements and financial highlights for the
other portfolios are presented in separate semi-annual reports.

The significant accounting policies consistently followed by the Portfolios are:
(a) security transactions are accounted for on trade date; (b) securities traded
on national securities markets are valued at the closing prices on such markets;
securities for which no sales price was reported and U.S. government agencies
and obligations are valued at the mean between bid and ask prices; (c)
securities maturing within 60 days are valued at cost plus accreted discount, or
minus amortized premium, which approximates value; (d) dividend income is
recorded on the ex-dividend date; foreign dividends are recorded on the
ex-dividend date or as soon as practical after the Portfolios determine the
existence of a dividend declaration after exercising reasonable due diligence;
(e) interest income is recorded on an accrual basis; (f) dividends and
distributions to shareholders are recorded on the ex-dividend date; (g) gains or
losses on the sale of securities are calculated by using the specific
identification method; (h) the accounting records of the Portfolios are
maintained in U.S. dollars. All assets and liabilities denominated in foreign
currencies are translated into U.S. dollars based on the rate of exchange of
such currencies against U.S. dollars on the date of valuation. Purchases and
sales of securities, and income and expenses are translated at the rate of
exchange quoted on the respective date that such transactions are recorded.
Differences between income or expense amounts recorded and collected or paid are
adjusted when reported by the custodian bank; (i) the character of income and
gains to be distributed are determined in accordance with income tax regulations
which may differ from generally accepted accounting principles. At October 31,
1997, reclassifications were made to the capital accounts of the Alliance Growth
Portfolio to reflect

permanent book/tax differences and income and gains available for distributions
under income tax regulations. Net investment income, net realized gains and net
assets were not affected by this adjustment; (j) the Portfolios intend to comply
with the requirements of the Internal Revenue Code of 1986, as amended,
pertaining to regulated investment companies and to make distributions of
taxable income sufficient to relieve it from substantially all Federal income
and excise taxes; and (k) estimates and assumptions are required to be made
regarding assets, liabilities and changes in net assets resulting from
operations when financial statements are prepared. Changes in the economic
environment, financial markets and any other parameters used in determining
these estimates could cause actual results to differ.

2. Management Agreement and Transactions with Affiliated Persons

Mutual Management Corp. ("MMC"), formerly known as Smith Barney Mutual Funds
Management Inc., a subsidiary of Salomon Smith Barney Holdings Inc. ("SSBH"),
acts as the investment manager of the Smith Barney Large Cap Value Portfolio
("SBLCV"). Travelers Investment Adviser, Inc. ("TIA"), an affiliate of MMC, acts
as the investment manager of the Alliance Growth ("AGP") and the Van Kampen
American Capital Enterprise ("VKACEP") Portfolios. SBLCV pays MMC a management
fee calculated at an annual rate of 0.65% of the average daily net assets of the
Portfolio. AGP and VKACEP pay TIA a management fee calculated at an annual rate
of 0.80% and 0.70%, respectively, of the average daily net assets of each
Portfolio. These fees are calculated daily and paid monthly.

TIA has entered into sub-advisory agreements with Alliance Capital Management
L.P. ("Alliance Capital") and Van Kampen American Capital Asset Management, Inc.
("VKAC"). Pursuant to each sub-advisory agreement, Alliance Capital and VKAC are
responsible for the day-to-day portfolio operations and investment decisions and
are compensated for such services at an annual rate of 0.375% and 0.325% of the
average daily net assets of AGP and VKACEP, respectively. These fees are
calculated daily and paid monthly.

TIA has entered into a sub-administrative services agreement with MMC. TIA pays
MMC, as sub-administrator, a fee calculated at an annual rate of 0.10% of the
average daily net assets of AGP and VKACEP.

Smith Barney Inc. ("SB"), another subsidiary of SSBH, acts as distributor of
Fund shares. For the six months ended April 30, 1998, SB received brokerage
commissions of $83,530.

All officers and one director of the Fund are employees of SB.

4. Repurchase Agreements

The Portfolios purchase (and their custodian takes possession of) U.S.
government securities from banks and securities dealers subject to agreements to
resell the securities to the sellers at a future date (generally, the next
business day) at an agreed-upon higher repurchase price. The Portfolios require
continual maintenance of the market value of the collateral in amounts at least
equal to the repurchase price.

5. Futures Contracts

Initial margin deposits made upon entering into futures contracts are recognized
as assets. Securities equal to the initial margin amount are segregated by the
custodian in the name of the broker. Additional securities are also segregated
up to the current market value of the futures contract. During the period the
futures contract is open, changes in the value of the contract are recognized as
unrealized gains or losses by "marking to market" on a daily basis to reflect
the market value of the contract at the end of each day's trading. Variation
margin payments are received or made and recognized as assets due from or
liabilities due to broker, depending upon whether unrealized gains or losses are
incurred. When the contract is closed, the Portfolios record a realized gain or
loss equal to the

difference between the proceeds from (or cost of) the closing transactions and
the Portfolios' basis in the contract.

Only AGP and VKACEP may enter into such contracts to hedge a portion of their
portfolios. The Portfolios bear the market risk that arises from changes in the
value of the financial instruments and securities indices (futures contracts).

At April 30, 1998, AGP and VKACEP had no open futures contracts.

6. Options Contracts

AGP and VKACEP may purchase put or call options. Premiums paid when put or call
options are purchased represent investments, which are marked-to-market daily
and are included in the schedule of investments. When a purchased option
expires, a loss will be realized in the amount of the premium paid. When a
closing sales transaction is entered into, a gain or loss will be realized
depending on whether the proceeds from the closing sales transaction are greater
or less than the premium paid for the option. When a put option is exercised, a
gain or loss will be realized from the sale of the underlying security and the
proceeds from such sale decrease by the premium originally paid. When a call
option is exercised, the cost of the security purchased upon exercise will be
increased by the premium originally paid.

At April 30, 1998, AGP and VKACEP had no open purchased put or call option
contracts.

When AGP and VKACEP write a covered call or put option, an amount equal to the
premium received is recorded as a liability, the value of which is
marked-to-market daily. When a written option expires, a gain equal to the
amount of the premium received is realized. When a closing purchase transaction
is entered into, a gain or loss is realized depending upon whether the cost of
the closing transaction is greater or less than the premium originally received,
without regard to any unrealized gain or loss on the underlying security, and
the liability related to such option is eliminated. When a written call option
is exercised, the cost of the security sold will be decreased by the premium
originally received. When a written put option is exercised, the amount of the
premium originally received will reduce the cost of the security purchased upon
exercise. When written index options are exercised, settlement is made in cash.

The risk associated with purchasing options is limited to the premium originally
paid. The Portfolios enter into options for hedging purposes. The risk in
writing a covered call option is that the Portfolios give up the opportunity to
participate in any increase in the price of the underlying security beyond the
exercise price. The risk

in writing a put option is that the Portfolios are exposed to the risk of a loss
if the market price of the underlying security declines.

During the six months ended April 30, 1998, AGP and VKACEP did not write any
options.

7. Lending of Portfolio Securities

SBLCV and AGP have an agreement with their custodian whereby the custodian may
lend securities owned by the Portfolios to brokers, dealers and other financial
organizations. Fees earned by the Portfolios on securities lending are recorded
as interest income. Loans of securities by the Portfolios are collateralized by
cash, U.S. government securities or high quality money market instruments that
are maintained at all times in an amount at least equal to the current market
value of the loaned securities, plus a margin depending on the type of
securities loaned. The custodian establishes and maintains the collateral in
segregated accounts. The Portfolios maintain exposure for the risk of any losses
in the investment of amounts received as collateral.

At April 30, 1998, there were no securities on loan.

8. Capital Shares

At April 30, 1998, the Fund had six billion shares authorized with a par value
of $0.00001 per share. Each share of a Portfolio represents an equal
proportionate interest in that Portfolio with each other share of the same
Portfolio and has an equal entitlement to any dividends and distributions made
by the Portfolio.

Transactions in shares of each Portfolio were as follows:

Proposal 2 requested that shareholders approve certain changes to the
fundamental policies of the Portfolios in order to modernize them in view of
certain regulatory, business or industry developments that have occurred since
original adoption of these policies by the Portfolios. The following chart
demonstrates that all proposals were approved by shareholders.

Please note that "M" indicates a modification of the policy; "E" indicates the
elimination of the policy; and "R" indicates the reclassification of the policy
from fundamental (which would require shareholder approval to change) to
non-fundamental (which can be changed by a vote of the Board of Directors).

Dear Shareholder:

We are pleased to provide the semi-annual report for the Travelers Series Fund
Inc. - MFS Total Return, TBC Managed Income and Smith Barney Money Market
Portfolios ("Portfolios") for the period ended April 30, 1998. For your
convenience, we have summarized the period's prevailing economic and market
conditions and outlined each Portfolio's investment strategy. A detailed summary
of performance and current holdings can be found in the appropriate sections
that follow.

Portfolio Highlights
MFS Total Return Portfolio

The primary investment objective of the MFS Total Return Portfolio ("Portfolio")
is to obtain above-average income (compared to a portfolio entirely invested in
stocks) consistent with the prudent employment of capital. While current income
is the primary objective, the Portfolio's managers believe there should also be
a reasonable opportunity for growth of capital and income since many of the
securities offering a better-than-average yield may also possess growth
potential.

For the six months ended April 30, 1998 the Portfolio provided a total return of
11.82%. This compares to the 22.50% return for the Standard and Poor's 500
Composite Index ("S&P 500"), a popular, unmanaged index of common stock total
return performance, and to the 3.64% return for the Lehman Brothers Government
Corporate Bond Index, an unmanaged, market-value-weighted index of U.S. Treasury
and government-agency securities (excluding mortgage-backed securities) and
investment-grade domestic corporate debt. As a balanced fund, a large portion of
the Portfolio's total assets are invested in both stocks and bonds. In addition,
the Portfolio purchases preferred stocks and convertible bonds, which in many
cases can provide similar returns to common stocks but with less risk.

In general, the Portfolio has been helped by the strong pace of economic
activity and low levels of inflation during the past six months. This strong
macroeconomic environment has lead to higher corporate profits and rising stock
prices. Investors have responded by pouring money into the stock market, which
in turn has served to drive stock prices even higher.

Within the Portfolio, the managers' allocations remained conservative. For most
of the period, the Portfolio's stock weighting was between 55% and 58%. In
addition, the managers' stock selection process remains conservative, as they
have added to their existing holdings in utility stocks and insurance company
stocks.

In selecting stocks for the Portfolio, the portfolio managers look for large
companies with solid market positions or franchises that are "undervalued"
relative to their peer group in the S&P 500. Generally, the stocks in the
portfolio have lower levels of volatility then the overall stock market.

Financial services companies have a lot of characteristics the managers seek.
Their valuations relative to the S&P 500 are low, but their earnings visibility
is higher than that of the average company. Many of the earnings growth rates of
these companies are in the double digits, and their yields are attractive. Add
to that the huge consolidation that's going on in financial services, and the
managers think this remains a great sector.

The portfolio managers also see some attractive valuations in the utilities and
communications sectors. On the electric side, they think growth is modest but
valuations are good relative to the S&P 500. In telecommunications, they see
lots of consolidation, solid long-term growth rates and decent valuations.

While many of their stock picks have helped the overall Portfolio, some groups
have lagged during the reporting period. For example, the Portfolio's energy
stocks underperformed during the past six months. Oil supplies loosened up
during the period causing the price of oil to fall. This lead to
lower-than-expected earnings and weaker-than-expected stock appreciation. The
Portfolio's managers believe that energy stocks are undervalued and they remain
an integral part of the Portfolio.

The bond allocation is overweighted in the corporate bond sector. The managers
believe that as long as the economy is sound and inflation remains low, these
issues should do well.

Looking ahead, the biggest risk the managers have identified is probably
valuation levels. There has been a deceleration in earnings growth in the S&P
500 over the past several months, brought about in part by the Asian crisis but
also because this economic expansion is in its latter stages. Still, stock
prices have continued to go up, which means there has been higher priced but
decelerating earnings growth. As a result, the portfolio managers finally
believe the valuation risk in the markets are greater today than in the past.

TBC Managed Income Portfolio

The TBC Managed Income Portfolio's investment objective is to seek high current
income consistent with what The Boston Company Asset Management, LLC, believes
to be prudent risk of capital through investments in corporate debt obligations
(such as bonds, debentures, obligations convertible into common stocks and money
market instruments); preferred stocks; and obligations issued or guaranteed by
the U.S. government and its agencies or instrumentalities.

For the six months ended April 30, 1998, the Portfolio had a total return of
3.98% versus the total return of 3.59% for the Lehman Brothers Aggregate Bond
Index, an unmanaged bond index made up of more than 5,900 issues of U.S.
Treasuries and agencies, corporate bonds, mortgage-backed, and asset-backed
securities. In general the Portfolio's performance was helped by its allocation
in corporate bonds (both high yield and investment grade) and mortgage-backed
securities.

During the previous six months, the Portfolio's managers have maintained
approximately a 48% allocation in corporate securities. Approximately 22% of the
Portfolio was allocated to high yield bonds and the rest of the corporate bonds
were investment grade. As of April 30, 1998, industrials made up 24.3% of the
Portfolio and financial services 10.0%. The Portfolio has benefited from the
strong corporate allocation as corporate bonds have outperformed U.S. Treasuries
on a duration-adjusted basis. In particular, the Portfolio's finance holdings
have done well in this low interest-rate environment. Brokerage houses have seen
their spreads tighten, as their financial results have been strong. With the
Asian markets stabilizing, the fundamental environment for most companies has
remained quite positive, which is expected to provide continued support for
corporate bonds in the coming months. Credit fundamentals in the high yield bond
market remained positive throughout the reporting period. Companies in the
telecommunications and media sector benefited from strong product demand and
increased merger activity. The Portfolio benefited from the rating upgrades of
Tenet Healthcare, Niagara, Mohawk, Nextel Communications and McLeod
Communications.

Mortgage-backed securities outperformed comparable U.S. Treasuries by
approximately 50 basis points over the course of the period, with returns being
tempered by the highest prepayment speeds observed since 1993. The managers
increased the Portfolio's exposure to agency pass-throughs after the mortgage
spread to U.S. Treasuries widened. The managers continue to seek relative value
between all of the bond market sectors with a particular focus on corporate
bonds and mortgage-backed securities while emphasizing security selection within
these bond market sectors as their primary means for adding value.

Smith Barney Money Market Portfolio

The Smith Barney Money Market Portfolio seeks maximum current income and
preservation of capital. Investors should be aware that their investment in the
Portfolio is neither insured nor guaranteed by the U.S. government. The
Portfolio will seek to maintain a stable net asset value of $1.00 per share;
however, there is no assurance that it will be able to do so at all times.

The U.S. economy continues to grow steadily as the seventh year of economic
expansion concludes. Toward the end of 1997, it looked as if the turmoil in Asia
would cause a considerable downturn in U.S. economic growth. This fostered
concern about weaker exports, a stronger U.S. dollar and a possible Federal
Reserve Board ("Fed") monetary policy easing. Nevertheless, one month into the
second quarter of 1998, U.S. economic growth remains strong and any talk of
lower rates appeared to be premature.

In his semi-annual address to Congress in February 1998, Fed Chairman Alan
Greenspan eliminated any near-term easing prospects for interest rates.
Greenspan noted that "the key question going forward is whether the weakness in
Asia will be sufficient to check inflationary tendencies that might otherwise
result from the strength of domestic spending and tightening labor markets." As
a result, the Fed has kept short-term interest rates steady. The last time the
Fed changed the federal-funds rate was in March 1997. (The federal-funds rate is
the interest rate banks charge each other for overnight loans and a closely
watched indicator of the direction of interest rates.) The combination of firm
economic growth and relatively no inflation has left little need for a change in
monetary policy. Fed officials have more recently chosen to take a
"wait-and-see" approach.

In the U.S., the Portfolio's managers continue to see strong consumer demand,
solid job growth and a robust housing market. All of which is supported by a
strong stock market, rising personal incomes and unseasonably warm weather. As
of this writing, the U.S. unemployment rate stands at 4.7%. This low employment
has led to a shortage of qualified workers and has caused wages to rise. The
Employment Cost Index, a broad measure of wages, salaries and benefit costs,
rose only 0.7% in the first quarter of 1998 after rising 1% in the fourth
quarter of 1997. For the first quarter 1998, GDP grew at a 4.2% annual rate,
following a 3.7% pace in 1997.

We have yet to see higher consumer prices because global competition has left
little room for manufacturers to pass on any higher production costs. Wage gains
have provided a boost to U.S. consumption.

The short-term yield curve remains fairly flat and is priced to no action by the
Fed. (The yield curve shows the difference between short- and long-term yields.)
The difference in yields between overnight investments and one-year certificates
of deposit has narrowed to less than 35 basis points. The Portfolio's managers
continue to buy securities primarily with a maturity between three and six
months and they are maintaining an average maturity in the Portfolio in the
mid-50 day range.

In closing, thank you for investing in the Travelers Series Fund Inc. - MFS
Total Return, TBC Managed Income and Smith Barney Money Market Portfolios. We
look forward to helping you pursue your investment goals.

Sincerely,

+    Hypothetical illustration of $10,000 invested in shares of the TBC Managed
     Income Portfolio on June 16, 1994 (commencement of operations), assumes
     reinvestment of dividends and capital gains, if any, at net asset value
     through April 30, 1998. The Lehman Brothers Aggregate Bond Index is
     comprised of over 6,500 issues of U.S. Treasuries, Agencies, Corporate
     Bonds and Mortgage-Backed securities. The index is unmanaged and is not
     subject to the same management and trading expenses of a mutual fund.

     All figures represent past performance and are not a guarantee of future
     results. Investment returns and principal value will fluctuate, and
     redemption value may be more or less than the original cost.

================================================================================
Bond Ratings (unaudited)
================================================================================
All ratings are by Standard & Poor's Ratings Services ("Standard & Poor's"),
except that those identified by an asterisk (*) are rated by Moody's Investors
Service Inc. ("Moody's"). The definitions of the applicable rating symbols are
set forth below:

Standard & Poor's -- Ratings from "AA" to "CCC" may be modified by the addition
of a plus (+) or minus (-) sign to show relative standings within the major
rating categories.

AAA   -- Bonds rated "AAA" have the highest rating assigned by Standard &
         Poor's. Capacity to pay interest and repay principal is extremely
         strong.

AA    -- Bonds rated "AA" have a very strong capacity to pay interest and repay
         principal and differs from the highest rated issue only in a small
         degree.

A     -- Bonds rated "A" have a strong capacity to pay interest and repay
         principal although it is somewhat more susceptible to the adverse
         effects of changes in circumstances and economic conditions than bonds
         in higher rated categories.

BBB   -- Bonds rated "BBB" are regarded as having an adequate capacity to pay
         interest and repay principal. Whereas they normally exhibit adequate
         protection parameters, adverse economic conditions or changing
         circumstances are more likely to lead to a weakened capacity to pay
         interest and repay principal for bonds in this category than in higher
         rated categories.

BB, B -- Bonds rated "BB" and "B" are regarded, on balance, as predominantly    
and      speculative with respect to capacity to pay interest and repay         
CCC      principal in accordance with the terms of the obligation. "BB"         
         represents a lower degree of speculation than "B," and "CCC" the       
         highest degree of speculation. While such bonds will likely have some  
         quality and protective characteristics, these are outweighted by large 
         uncertainties or major risk exposure to adverse conditions.            
      
Moody's-- Numerical modifiers 1, 2 and 3 may be applied to each generic rating
from "A" to "Caa," where 1 is the highest and 3 the lowest rating within its
generic category.

A     -- Bonds that are rated "A" possess many favorable investment attributes
         and are to be considered as upper medium grade obligations. Factors
         giving security to principal and interest are considered adequate but
         elements may be present which suggest a susceptibility to impairment
         some time in the future.

Baa   -- Bonds that are rated "Baa" are considered as medium grade obligations,
         i.e., they are neither highly protected nor poorly secured. Interest
         payments and principal security appear adequate for the present but
         certain protective elements may be lacking or may be characteristically
         unreliable over any great length of time. Such bonds lack outstanding
         investment characteristics and in fact have speculative characteristics
         as well.

Ba    -- Bonds that are rated "Ba" are judged to have speculative elements;
         their future cannot be considered as well assured. Often the protection
         of interest and principal payments may be very moderate thereby not
         well safeguarded during both good and bad times over the future.
         Uncertainty of position characterizes bonds in this class.

B     -- Bonds that are rated "B" generally lack characteristics of desirable
         investments. Assurance of interest and principal payments or of
         maintenance of other terms of the contract over any long period of time
         may be small.

Caa   -- Bonds that are rated "Caa" are of poor standing. These issues may be in
         default, or present elements of danger may exist with respect to
         principal or interest.

NR    -- Indicates that the bond is not rated by Standard & Poor's or Moody's.

1.   Significant Accounting Policies

The MFS Total Return, TBC Managed Income and Smith Barney Money Market
Portfolios ("Portfolio(s)") are separate investment portfolios of the Travelers
Series Fund Inc. ("Fund"). The Fund, a Maryland corporation, is registered under
the Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company and consists of these Portfolios and ten other
separate investment portfolios: Alliance Growth, AIM Capital Appreciation, GT
Global Strategic Income, Putnam Diversified Income, Smith Barney High Income,
Smith Barney Large Cap Value (formerly known as Smith Barney Income and Growth
Portfolio), Smith Barney International Equity, Smith Barney Pacific Basin, Smith
Barney Large Capitalization Growth and Van Kampen American Capital Enterprise
Portfolios. Shares of the Fund are offered only to insurance company separate
accounts that fund certain variable annuity and variable life insurance
contracts. The financial statements and financial highlights for the other
portfolios are presented in separate semi-annual reports.

The significant accounting policies consistently followed by the Portfolios are:
(a) security transactions are accounted for on trade date; (b) the Smith Barney
Money Market Portfolio uses the amortized cost method for valuing all of its
portfolios securities; the MFS Total Return and TBC Managed Income Portfolios
use the amortized cost method for valuing securities with maturities less than
60 days, accordingly, the cost of securities plus accreted discount or minus
amortized premium, approximates value; (c) securities traded on national
securities markets are valued at the closing prices on such markets; securities
for which no sales price was reported and U.S. government agencies and
obligations are valued at the mean between the bid and ask prices; (d) dividend
income is recorded on the ex-dividend date; foreign dividends are recorded on
the ex-dividend date or as soon as practical after the Portfolio determines the
existence of a dividend declaration after exercising reasonable due diligence;
(e) gains or losses on the sale of securities are calculated by using the
specific identification method; (f) interest income, adjusted for amortization
of premium and accretion of discount, is recorded on an accrual basis; (g)
dividends and distributions to shareholders are recorded on the ex-dividend
date; (h) the accounting records of the Portfolios are maintained in U.S.
dollars. All assets and liabilities denominated in foreign currencies are
translated into U.S. dollars based on the rate of exchange of such currencies
against U.S. dollars on the date of valuation. Purchases and sales of
securities, and income and expenses are translated at the rate of exchange
quoted on the respective date that such transactions are recorded. Differences
between income or expense amounts recorded and collected or paid are adjusted
when reported by the custodian bank; (i) the character of income and gains to be
distributed are determined in accordance with income tax regulations which may
differ from generally accepted accounting

principles. At October 31, 1997, reclassifications were made to the capital
accounts of the MFS Total Return Portfolio and the TBC Managed Income Portfolio
to reflect permanent book/tax differences and income and gains available for
distributions under income tax regulations. Accordingly, a portion of
undistributed net investment income amounting to $2,784 was reclassified to
paid-in capital for the TBC Managed Income Portfolio. Net investment income, net
realized gains and net assets were not affected by this change; (j) the
Portfolios intend to comply with the requirements of the Internal Revenue Code
of 1986, as amended, pertaining to regulated investment companies and to make
distributions of taxable income sufficient to relieve it from substantially all
Federal income and excise taxes; and (k) estimates and assumptions are required
to be made regarding assets, liabilities and changes in net assets resulting
from operations when financial statements are prepared. Changes in the economic
environment, financial markets and any other parameters used in determining
these estimates could cause actual results to differ.

2.   Dividends

The Smith Barney Money Market Portfolio declares and records a dividend of
substantially all its net investment income on each business day. Such dividends
are paid or reinvested monthly on the payable date.

3.   Management Agreement and Transactions with Affiliated Persons

Mutual Management Corp. ("MMC"), formerly known as Smith Barney Mutual Funds
Management Inc., a subsidiary of Salomon Smith Barney Holdings Inc. ("SSBH"),
acts as investment manager of the Smith Barney Money Market Portfolio ("SBMM").
Travelers Investment Adviser, Inc. ("TIA"), an affiliate of MMC, acts as the
investment manager of the MFS Total Return ("MFSTR") and the TBC Managed Income
("TBCMI") Portfolios. Effective March 27, 1998, the management fee SBMM pays MMC
was decreased from an annual rate of 0.60% to 0.50% of the average daily net
assets of the Portfolio. MFSTR and TBCMI pay TIA a management fee calculated at
an annual rate of 0.80% and 0.65%, respectively, of the average daily net assets
of each Portfolio. These fees are calculated daily and paid monthly.

TIA has sub-advisory agreements with Massachusetts Financial Services Company
("MFS") and The Boston Company Asset Management, Inc. ("TBC"). Pursuant to each
sub-advisory agreement, MFS and TBC are responsible for the day-to-day portfolio
operations and investment decisions for MFSTR and TBCMI, respectively, and are
compensated for such services at an annual rate of 0.375% and 0.30%,
respectively, of the average daily net assets of MFSTR and TBCMI. These fees are
calculated daily and paid monthly.

average daily net assets of MFSTR and TBCMI.

Fund shares.

All officers and one Director of the Fund are employees of SB.

6.   Repurchase Agreements

The Portfolios purchase (and their custodian takes possession of) U.S.
government securities from banks and securities dealers subject to agreements to
resell the securities to the sellers at a future date (generally, the next
business day) at an agreed-upon higher repurchase price. The Portfolios require
continual maintenance of the market value of the collateral in amounts at least
equal to the repurchase price.

7.   Futures Contracts

MFSTR has the ability to enter into futures contracts.

Initial margin deposits made upon entering into futures contracts are recognized
as assets. Securities equal to the initial margin amount are segregated by the
custodian in the name of the broker. Additional securities are also segregated
up to the current market value of the futures contracts. During the period the
futures contract is open, changes in the value of the contract are recognized as
unrealized gains or losses by "marking to market" on a daily basis to reflect
the market value of the contract at the end of each day's trading. Variation
margin payments are received or made and recognized as assets due from or
liabilities due to broker, depending upon whether unrealized gains or losses are
incurred. When the contract is closed, the Portfolio records a realized gain or
loss equal to the difference between the proceeds from (or cost of) the closing
transactions and the Portfolio's basis in the contract. MFSTR enters into such
contracts to hedge a portion of its portfolio. The Portfolio bears the market
risk that arises from changes in the value of the financial instruments and
securities indices (futures contracts).

At April 30, 1998, MFSTR had no open futures contracts.

8.   Lending of Portfolio Securities

The Portfolios have an agreement with their custodian whereby the custodian may
lend securities owned by the Portfolios to brokers, dealers and other financial
organizations. Fees earned by the Portfolios on securities lending are recorded
as interest income. Loans of securities by the Portfolios are collateralized by
cash, U.S. government securities or high quality money market instruments that
are maintained at all times in an amount at least equal to the current market
value of the loaned securities, plus a margin which may vary between 2% and 5%
depending on the type of securities loaned. The custodian establishes and
maintains the collateral in segregated accounts.

At April 30, 1998, the Portfolios had no securities on loan.

9.   Options Contracts

Premiums paid when put or call options are purchased by the Portfolios represent
investments, which are marked-to-market daily and are included in the schedule
of investments. When a purchased option expires, the Portfolios will realize a
loss in the amount of the premium paid. When the Portfolios enter into a closing
sales transaction, the Portfolios will realize a gain or loss depending on
whether the proceeds from the closing sales transaction are greater or less than
the premium paid for the option. When the Portfolios exercise a put option, they
will realize a gain or loss from the sale of the underlying security and the
proceeds from such sale will be decreased by the premium originally paid. When
the Portfolios exercise a call option, the cost of the security which the
Portfolios purchase upon exercise will be increased by the premium originally
paid.

At April 30, 1998, the Portfolios had no open purchased put or call option
contracts.

When the Portfolios write a covered call or put option, an amount equal to the
premium received by the Portfolios is recorded as a liability, the value of
which is marked-to-market daily. When a written option expires, the Portfolios
realize a gain. When the Portfolios enter into a closing purchase transaction,
the Portfolios realize a gain or loss depending upon whether the cost of the
closing transaction is greater or less than the premium originally received
without regard to any unrealized gain or loss on the underlying security, and
the liability related to such option is eliminated. When a written call option
is exercised, the cost of the security sold will be decreased by the premium
originally received. When a put option is exercised, the amount of the premium
originally received will reduce the cost of the security which the Portfolios
purchased upon exercise. When the written index options are exercised,
settlement is made in cash.

The risk associated with purchasing options is limited to the premium originally
paid. The Portfolios enter into options for hedging purposes. The risk in
writing a covered call option is that the Portfolios give up the opportunity to
participate in any increase in the price of the underlying security beyond the
exercise price. The risk in writing a put option is that the Portfolios are
exposed to the risk of a loss if the market price of the underlying security
declines.

During the period ended April 30, 1998, the Portfolios did not write any
options.

10.  Securities Traded on a To-Be-Announced Basis

The Portfolios may trade securities on a "to-be-announced" ("TBA") basis. In a
TBA transaction, the Portfolios commits to purchasing or selling securities for
which specific information is not yet known at the time of the trade,
particularly the face amount and maturity date in GNMA transactions. Securities
purchased on a TBA basis are not settled until they are delivered to the
Portfolios normally 15 to 45 days later. These transactions are subject to
market fluctuations and their current value is determined in the same manner as
for other securities.

At April 30, 1998, TBCMI held seven TBA securities with a cost of $9,274,542.

11.  Capital Shares

At April 30, 1998, the Fund had six billion shares of capital stock authorized
with a par value of $0.00001 per share. Each share of a Portfolio represents an
identical interest in that Portfolio with each share of the same Portfolio and
has an equal entitlement to any dividends and distributions made by the
Portfolio.

Transactions in shares of each Portfolio were as follows:

Proposal 2 requested that shareholders approve certain changes to the
fundamental investment policies of the Portfolios in order to modernize them in
view of certain regulatory, business or industry developments that have occurred
since original adoption of these policies by the Portfolios. The following chart
demonstrates that all proposals were approved by shareholders.

Please note that "M" indicates a modification of the policy; "E" indicates the
elimination of the policy; and "R" indicates the reclassification of the policy
from fundamental (which would require shareholder approval to change) to
non-fundamental (which can be changed by a vote of the Board of Directors).

We are pleased to provide the semi-annual report of the Travelers Series Fund
Inc. -- AIM Capital Appreciation Portfolio ("Portfolio") for the period ended
April 30, 1998. In this report, we summarize the period's prevailing economic
and market conditions and outline our portfolio strategy. A detailed summary of
performance and current holdings can be found in the appropriate sections that
follow.

Portfolio Performance Update

The Portfolio seeks capital appreciation. Toward the end of the reporting
period, it seemed that investors were finally beginning to question their
preference for very large company stocks. Nevertheless, throughout the reporting
period, the mid-cap and smaller issues in which the Portfolio invests were out
of favor compared to large-capitalization stocks.

For the six months ended April 30, 1998, the total return for the Portfolio was
10.33%. This compares unfavorably to the 19.17% total return for the Standard &
Poor's Midcap 400 Index ("S&P 400 Index") of mid-capitalization stocks and the
17.24% return for the small-cap dominated Nasdaq Index. (The S&P 400 Index is an
unmanaged index made up of the common stocks of approximately 400
mid-capitalization companies.) By contrast, the large-capitalization company
dominated Standard & Poor's 500 Index rose 22.47% during the six months ended
April 30, 1998. (The S&P 500 Index is a capitalization-weighted measure of 500
widely held common stocks.)

Market Recap

The six-month period covered by this report had two distinct phases. During the
first half of the period, fallout from the currency and market crises in several
Asian nations dampened stock market performance dramatically. When markets are
shaky, investors tend to gravitate toward well-known, widely traded blue-chip
stocks, so the midsize and smaller companies that the Portfolio invests in were
especially hard hit. For example, the Portfolio produced a negative total return
for the first three months of the reporting period.

But the financial markets seemed to shrug off these difficulties as the new year
unfolded. A much-anticipated slowdown in the U.S. economy predicted to result
from the troubles in Asia never materialized. In fact, government data showed
U.S. gross domestic output rising at a 4.2% annual rate during the first quarter
of 1998. But inflation, widely believed to result from such robust economic
expansion, remained low. In fact, the Commerce Department's overall price index
rose an annualized 0.9% during the quarter -- its slowest rate in 34 years.

With expectations of a good economy, both the markets and the Portfolio
rebounded early in 1998. During the second three months of the reporting period,
the Portfolio rose roughly 12%.

Investment Strategy

The Portfolio continued to find opportunities in the retail and health-care
industries. The portfolio managers pared their holdings of energy stocks while
technology stocks in such industries as electronics, computers and computer
software remained the Portfolio's largest sector weighting.

Retail

As is to be expected, consumer cyclicals in general, and retailers in
particular, are doing very well in the current excellent economic expansion.
Personal earnings are up, and the Conference Board, a business research
organization, reported consumer confidence at a 29-year high in February. Good
times are buoying both discounters and sellers of high-profile brands.
Electronics-oriented stores are experiencing a sales rise with the arrival of
sub-$1,000 personal computers, among other products. The Portfolio's retail
holdings were among its best performers in early 1998.

Health Care

The Portfolio's health-care holdings also did well during the reporting period,
as a number of HMOs and other care providers were able to raise premiums for the
first time in years. Consolidation and cost cutting in the health care sector
have helped profit margins for many service providers while the FDA's gradual
streamlining of filing the approval systems has been a boon to many
pharmaceutical companies, especially those with new products or new drug
delivery systems.

Technology

Technology was not generally in favor for much of the reporting period, mainly
due to disappointing earnings from a few leading companies. Overall, this sector
has still performed well; for example, personal computer sales were up 16% in
the U.S. during the first quarter of 1998, with strong growth expected to
continue. In addition to hardware makers, the Portfolio has significant holdings
in the software industry. The Year 2000 problem continues to provide ample

work for companies with expertise in reprogramming computers to recognize this
date. Semiconductor holdings were pared down during the reporting period while
holdings in computer software were increased. Within the semiconductor industry,
the portfolio managers believe the makers of proprietary products remain far
more attractive than commodity manufacturers because of overcapacity.

Energy

Though energy stocks turned in very attractive performance for most of 1997,
these stocks could not maintain their momentum into the new year. The formerly
high-growth economies of Asia were significant energy users, and many investors
anticipated that as Asia's economic growth faltered, so would their demand for
oil and other energy products. Moreover, commodity prices in general fell
sharply in the make of Asia's financial difficulties. The Portfolio's holdings
in the energy sector were trimmed during the reporting period. The managers
continue to hold a number of oilfield-service companies, which are less closely
tied to the price of oil than drillers are. Many service companies have
contracts locked in for 1998 and 1999, so their revenues are relatively
predictable.

The portfolio managers believe the negative reaction to the energy and
technology sectors may be overblown. While economic growth in Asia has declined,
growth remains robust in the U.S., Europe and most developing nations. In
technology, a sizable proportion of electronic components made in Southeast Asia
goes to computer manufacturers in the U.S., therefore Asia's currency woes are
cutting these manufacturer's costs, not their markets.

Market Outlook

Almost unnoticed by the popular or business press, the dominance of very
large-capitalization stocks had slipped somewhat by the end of this reporting
period. For the three months ending April 30, 1998, S&P 400 Index outperformed
the large-cap S&P 500 Index. In our view, values in the mid-cap sector may
simply be more attractive. Earnings of mid-cap and smaller companies are growing
in the double digits and are projected to continue growing at high rates,
whereas actual first-quarter year-over-year earnings growth for the large
companies represented by the S&P 500 Index was in the single digits. The
managers believe you simply get more earnings by investing in smaller and
mid-cap stocks given the ultra high price/earnings ratios of many blue-chip
stocks. The portfolio managers expect this should ultimately translate into
continued strong performance for select mid-size company stocks.

With respect to the investing environment in general, most observers do not
expect dramatic change; they still foresee stable to lower interest rates,
healthy economic growth and subdued inflation as global competition and lower
energy costs offset any inflationary pressures of a tight labor market. In the
view of the portfolio's managers, no one has identified a good reason why the
seven-plus years of domestic economic expansion should end abruptly.

However, most investors would probably welcome some cooling off. One of the
events most likely to trigger a halt in the market's prolonged rise would be an
interest rate hike by the Federal Reserve Board, which has been hinting about
its concern over rapid economic growth and the dramatic rise in stock values. An
interest rate move would be forestalled by evidence that the economy is growing
a little less rapidly.

In closing, thank you for investing in the Travelers Series Fund Inc. -- AIM
Capital Appreciation Portfolio. We look forward to continuing to help you to
pursue your financial goals.

Sincerely,

1.   Significant Accounting Policies

The AIM Capital Appreciation Portfolio ("Portfolio") is a separate investment
portfolio of the Travelers Series Fund Inc. ("Fund"). The Fund, a Maryland
corporation, is registered under the Investment Company Act of 1940, as amended,
as an open-end management investment company and consists of this portfolio and
twelve other separate investment portfolios: Smith Barney Large Cap Value
(formerly known as Smith Barney Income and Growth), Alliance Growth, Van Kampen
American Capital Enterprise, Smith Barney International Equity, Smith Barney
Pacific Basin, TBC Managed Income, Putnam Diversified Income, GT Global
Strategic Income, Smith Barney High Income, MFS Total Return, Smith Barney Large
Capitalization Growth and Smith Barney Money Market Portfolios. Shares of the
Fund are offered only to insurance company separate accounts that fund certain
variable annuity and variable life insurance contracts. The financial statements
and financial highlights for the other portfolios are presented in separate
semi-annual reports.

The significant accounting policies followed by the Portfolio are: (a) security
transactions are accounted for on trade date; (b) securities traded on national
securities markets are valued at the closing prices on such markets; securities
for which no sales price was reported and U.S. government agencies and
obligations are valued at the mean between the bid and asked prices; (c)
securities maturing within 60 days are valued at cost plus accreted discount or
minus amortized premium, which approximates value; (d) interest income is
recorded on an accrual basis; (e) dividend income is recorded on the ex-dividend
date; foreign dividends are recorded on the ex-dividend date or as soon as
practical after the Portfolio determines the existence of a dividend declaration
after exercising reasonable due diligence; (f) gains or losses on the sale of
securities are calculated by using the specific identification method; (g) the
accounting records of the Portfolio are maintained in U.S. dollars. All assets
and liabilities denominated in foreign currencies are translated into U.S.
dollars based on the rate of exchange of such currencies against U.S. dollars on
the date of valuation. Purchases and sales of securities, and income and
expenses are translated at the rate of exchange quoted on the respective date
that such transactions are recorded. Differences between income or expense
amounts recorded and collected or paid are adjusted when reported by the
custodian; (h) the character of income and gains to be distributed are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles; (i) the Portfolio intends to comply
with the applicable provisions of the Internal Revenue Code of 1986, as amended,
pertaining to regulated investment companies and to make

distributions of taxable income sufficient to relieve it from substantially all
Federal income and excise taxes; and (j) estimates and assumptions are required
to be made regarding assets, liabilities and changes in net assets resulting
from operations when financial statements are prepared. Changes in the economic
environment, financial markets and any other parameters used in determining
these estimates could cause actual results to differ.

2.   Management Agreement and Transactions with Affiliated Persons

Travelers Investment Adviser, Inc. ("TIA"), acts as investment manager of the
Fund. The Portfolio pays TIA a management fee calculated at an annual rate of
0.80% on the average daily net assets. This fee is calculated daily and paid
monthly.

TIA has entered into a sub-advisory agreement with AIM Capital Management, Inc.
("AIM"). Pursuant to the sub-advisory agreement, AIM is responsible for the
day-to-day portfolio operations and investment decisions and is compensated for
such service at the annual rate of 0.375% of the Portfolio's average daily net
assets. TIA pays this fee to AIM on a monthly basis.

TIA has entered into a sub-administrative services agreement with Mutual
Management Corp. ("MMC"), formerly known as Smith Barney Mutual Funds Management
Inc., a subsidiary of Salomon Smith Barney Holdings Inc. ("SSBH"). TIA pays MMC,
as sub-administrator, a fee calculated at an annual rate of 0.10% of the
Portfolio's average daily net assets.

Smith Barney Inc. ("SB"), another subsidiary of SSBH, acts as distributor of
Fund shares and primary broker for its portfolio agency transactions.

All officers and one Director of the Fund are employees of SB.

future capital gains, expiring October 31, 2004. To the extent that these
carryforward losses are used to offset capital gains, it is probable that the
gains so offset will not be distributed.

5.   Lending of Portfolio Securities

The Portfolio has an agreement with its custodian whereby the custodian may lend
securities owned by the Portfolio to brokers, dealers and other financial
organizations. Fees earned by the Portfolio on securities lending are recorded
as interest income. Loans of securities by the Portfolio are collateralized by
cash, U.S. government securities or high quality money market instruments that
are maintained at all times in an amount at least equal to the current market
value of the loaned securities, plus a margin which may vary depending on the
type of securities loaned. The custodian establishes and maintains the
collateral in a segregated account.

At April 30, 1998, the Porfolio had no securities on loan.

6.   Futures Contracts

Initial margin deposits made upon entering into futures contracts are recognized
as assets. Securities equal to the initial margin amount are segregated by the
custodian in the name of the broker. Additional securities are also segregated
up to the current market value of the futures contract. During the period the
futures contract is open, changes in the value of the contract are recognized as
unrealized gains or losses by "marking to market" on a daily basis to reflect
the market value of the contract at the end of each day's trading. Variation
margin payments are received or made and recognized as assets due from or
liabilities due to broker, depending upon whether unrealized gains or losses are
incurred. When the contract is closed, the Portfolio records a realized gain or
loss equal to the difference between the proceeds from (or cost of) the closing
transactions and the Portfolio's basis in the contract.

================================================================================
Notes to Financial Statements (unaudited) (continued)
================================================================================

The Portfolio enters into such contracts to hedge a portion of its portfolio.
The Portfolio bears the market risk that arises from changes in the value of the
financial instruments and securities indices (futures contracts).

At April 30, 1998, the Portfolio had no open futures contracts.

7.   Options Contracts

When a Portfolio writes a covered call option, an amount equal to the premium
received by the Portfolio is recorded as a liability, the value of which is
marked-to-market daily. When a written option expires, the Portfolio realizes a
gain equal to the amount of the premium received. When the Portfolio enters into
a closing purchase transaction, the Portfolio realizes a gain or loss depending
upon whether the cost of the closing transaction is greater or less than the
premium originally received, without regard to any unrealized gain or loss on
the underlying security, and the liability related to such option is eliminated.
When a written call option is exercised, the cost of the security sold will be
decreased by the premium originally received. When written index options are
exercised, settlement is made in cash.

The risk in writing a covered call option is that the Portfolio gives up the
opportunity to participate in any increase in the price of the underlying
security beyond the exercise price.

During the six months ended April 30, 1998, the Portfolio did not write any
covered call options.

8.   Capital Shares

At April 30, 1998, the Fund had six billion shares of capital stock authorized
with a par value of $0.00001 per share. Each share represents an equal
proportionate interest and has an equal entitlement to any dividends and
distributions made by the Portfolio.

Transactions in shares of the Portfolio were as follows:

Proposal 2 requested that shareholders approve certain changes to the
fundamental investment policies of the Porfolios in order to modernize them in
view of certain regulatory, business or industry developments that have occurred
since original adoption of these policies by the Portfolios. The following chart
demonstrates that all proposals were approved by shareholders.

Please note that "M" indicates a modification of the policy; "E" indicates the
elimination of the policy; and "R" indicates the reclassification of the policy
from fundamental (which would require shareholder approval to change) to
non-fundamental (which can be changed by a vote of the Board of Directors).
