R. JAY GERKEN, CFA
Chairman, President and Chief Executive Officer


Dear Shareholder,

Early this past summer bonds surrendered some of the gains they had generated
previously in 2003 due in part to signs of a sharp pick-up in the economy.
Despite subsequent reports of robust third-quarter economic growth, which
raised interest rate concerns, bond investors welcomed comments from the Fed
suggesting that it was likely to leave its interest rate targets at current
levels for the foreseeable future.

Please read on for a more detailed look at prevailing economic and market
conditions during the fund's fiscal year and to learn how those conditions and
changes made to the portfolio during this time may have affected fund
performance.

Information About Your Fund
In recent months several issues in the mutual fund industry have come under the
scrutiny of federal and state regulators. The fund's Adviser and some of its
affiliates have received requests for information from various government
regulators regarding market timing, late trading, fees and other mutual fund
issues in connection with various investigations. The regulators appear to be
examining, among other things, the fund's response to market timing and
shareholder exchange activity, including compliance with prospectus disclosure
related to these subjects. The fund has been informed that the Adviser and its
affiliates are responding to those information requests, but are not in a
position to predict the outcome of these requests and investigations.

As always, thank you for your confidence in our stewardship of your assets. We
look forward to helping you continue to meet your financial goals.

Sincerely,

/s/ R. Jay Gerken

Performance Review
For the 12 months ended December 31, 2003, Class A shares of the Smith Barney
Government Securities Fund, excluding sales charges, returned 1.83%. These
shares outperformed the fund's Lipper general U.S. government funds category
average, which returned 1.30% for the same period./1/ In comparison, the fund's
unmanaged benchmark, the Lehman Brothers Government Bond Index/i/ ("Index"),
returned 2.36% for the same period. During the period, the fund generally
benefited from its exposure to mortgage-backed securities, which modestly
outperformed U.S. Treasuries with comparable maturities.

Market Overview
When the period began, we believe concerns about a faltering economy and stock
market volatility, coupled with expectations that interest rates would drop,
triggered an investor flight to quality and led to increased demand for
investment-grade fixed-income securities. Because bond prices typically move
opposite to interest rate movements, many longer-term fixed-income securities
appreciated over the first five months of 2003.

The Fed proceeded to reduce its interest rate targets in June to their lowest
levels since the Eisenhower Administration. Shortly after the Fed's rate
reduction, signs suggested to many investors that gross domestic product
("GDP")/ii/ growth was stronger than expected, sparking concerns that inflation
could pick up. This led many to question whether the Fed's rate-cutting cycle

   All figures represent past performance and are not a guarantee of future
   results. Principal value and investment returns will fluctuate and
   investors' shares, when redeemed, may be worth more or less than their
   original cost.

   Class A share returns assume the reinvestment of income dividends and
   capital gains distributions at net asset value and the deduction of all fund
   expenses. Returns have not been adjusted to include sales charges that may
   apply when shares are purchased or the deduction of taxes that a shareholder
   would pay on fund distributions. Excluding sales charges, Class 1 shares
   returned -0.75%, Class B shares returned -1.17%, Class L shares returned
   -1.13% and Class Y shares returned -0.64% for the six months ended December
   31, 2003. Excluding sales charges, Class 1 shares returned 1.95%, Class B
   shares returned 1.30%, Class L shares returned 1.29% and Class Y shares
   returned 2.17% for the 12 months ended December 31, 2003.

   All index performance reflects no deduction for fees, expenses or taxes. The

had run its course, which resulted in rising bond yields and a sharp decline in
prices over the summer. The decline was exacerbated due to selling from certain
investors who held mortgage-backed securities in their portfolios.

Prices of Treasuries bounced back to some extent in September. Concerns about
rising interest rates resurfaced after the Commerce Department released
preliminary third-quarter data stating that the economy grew at its fastest
pace in almost 20 years. According to estimates that were revised higher later
in the quarter, GDP increased 8.2% over the quarter./iii/ However, selling in
the Treasury markets was more contained than it was in July, as we believed
some of this economic growth was attributable to one-time factors, such as the
tax cuts and end of major combat in Iraq, and many analysts and investors felt
that the Fed appeared to be in a holding pattern.

        3 Smith Barney Government Securities Fund | 2003 Annual Report





Portfolio Allocation Approach
We continued to allocate investment capital primarily between mortgage-backed
fixed-income securities and U.S. Treasuries through the end of the period,
while maintaining the ability to add exposure to other sectors when
opportunities arise. We have remained cautious in anticipation of the
possibility for a rise in rates. Therefore, we continued to underweight U.S.
Treasury bonds while allocating capital to mortgage-backed securities to seek
enhanced yields.

Thank you for your investment in the Smith Barney Government Securities Fund.
We appreciate that you have entrusted us to manage your money and value our
relationship with you.

        13 Smith Barney Government Securities Fund | 2003 Annual Report




 NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

The Smith Barney Government Securities Fund ("Fund"), a separate investment
fund of Smith Barney Investment Funds Inc. ("Company"), a Maryland corporation,
is registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company. The Company consists of
this Fund and eight other separate investment funds: Smith Barney Investment
Grade Bond, Smith Barney Hansberger Global Value, Smith Barney Small Cap Value,
Smith Barney Multiple Discipline Funds -- Large Cap Growth and Value (formerly
known as Smith Barney Premier Selections Large Cap), Smith Barney Multiple
Discipline Funds -- All Cap Growth and Value (formerly known as Smith Barney
Premier Selections All Cap Growth), Smith Barney Multiple Discipline
Funds -- Global All Cap Growth and Value (formerly known as Smith Barney
Premier Selections Global Growth), Smith Barney Group Spectrum and Smith Barney
Small Cap Growth Funds. The financial statements and financial highlights for
the other funds are presented in separate shareholder reports.

The significant accounting policies consistently followed by the Fund are:
(a) security transactions are accounted for on trade date; (b) securities
traded on national securities markets are valued at the closing price on such
markets; securities traded in the over-the-counter market and listed securities
for which no sales price was reported and U.S. government and government agency
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,
adjusted for amortization of premium and accretion of discount, is recorded on
the accrual basis; (e) gains or losses on the sale of securities are calculated
by using the specific identification method; (f) dividends and distributions to
shareholders are recorded on the ex-dividend date; the Fund distributes
dividends monthly and capital gains, if any, at least annually; (g) class
specific expenses are charged to each class; management fees and general
expenses are allocated on the basis of the relative net assets of each class or
on another reasonable basis; (h) 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; (i) the character of
income and gains to be distributed is determined in accordance with

        14 Smith Barney Government Securities Fund | 2003 Annual Report




 NOTES TO FINANCIAL STATEMENTS (CONTINUED)

income tax regulations which may differ from accounting principles generally
accepted in the United States of America. At December 31, 2003,
reclassifications were made to the Fund's capital accounts 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 change; and (j) the Fund 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.

2. Investment Advisory Agreement, Administration Agreement and Other
   Transactions

Smith Barney Fund Management LLC ("SBFM"), an indirect wholly-owned subsidiary
of Citigroup Inc. ("Citigroup"), acts as investment adviser to the Fund. The
Fund pays SBFM an investment advisory fee calculated at the following annual
rates of the Fund's average daily net assets: 0.35% up to $2 billion, 0.30% on
the next $2 billion, 0.25% on the next $2 billion, 0.20% on the next $2 billion
and then 0.15% of the Fund's remaining average daily net assets. This fee is
calculated daily and paid monthly.

SBFM also acts as the Fund's administrator for which the Fund pays a fee
calculated at an annual rate of 0.20% of the Fund's average daily net assets.
This fee is calculated daily and paid monthly.

Citicorp Trust Bank, fsb. ("CTB"), another subsidiary of Citigroup, acts as the
Fund's transfer agent. PFPC Inc. ("PFPC") and Primerica Shareholder Services
("PSS") act as the Fund's sub-transfer agents. CTB receives account fees and
asset-based fees that vary according to the size and type of account. PFPC and
PSS are responsible for shareholder recordkeeping and financial processing for
all shareholder accounts and are paid by CTB. During the year ended December
31, 2003, the Fund paid transfer agent fees of $508,881 to CTB.

Citigroup Global Markets Inc. ("CGM") (formerly known as Salomon Smith Barney
Inc.) and PFS Distributors, Inc., both of which are subsidiaries of Citigroup,
act as the Fund's distributors.

There are maximum initial sales charges of 6.75%, 4.50% and 1.00% for Class 1,
A and L shares, respectively. There is a contingent deferred sales charge

        15 Smith Barney Government Securities Fund | 2003 Annual Report



 NOTES TO FINANCIAL STATEMENTS (CONTINUED)


("CDSC") of 4.50% on Class B shares, which applies if redemption occurs within
one year from purchase payment. This CDSC declines by 0.50% the first year
after purchase payment and thereafter by 1.00% per year until no CDSC is
incurred. Class L shares also have a 1.00% CDSC, which applies if redemption
occurs within one year from purchase payment. In addition, Class A shares have
a 1.00% CDSC, which applies if redemption occurs within one year from purchase
payment. This CDSC only applies to those purchases of Class A shares which,
when combined with current holdings of Class A shares, equal or exceed $500,000
in the aggregate. These purchases do not incur an initial sales charge.

For the year ended December 31, 2003, CGM and its affiliates received sales
charges of approximately $111,000, $1,438,000 and $53,000 on sales of the
Fund's Class 1, A and L shares, respectively. In addition, for the year ended
December 31, 2003, CDSCs paid to CGM and its affiliates were approximately:



                               Class A Class B  Class L
                         ------------------------------
                                       
                         CDSCs $1,000  $478,000 $13,000
                         ------------------------------


All officers and one Director of the Company are employees of Citigroup or
its affiliates.

3. Investments

proceeds from sales of investments (including maturities of long-term
investments, but excluding short-term investments, mortgage dollar rolls and

 NOTES TO FINANCIAL STATEMENTS (CONTINUED)


4. Repurchase Agreements

The Fund purchases (and the custodian takes possession of) U.S. government
securities from 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 Fund requires continual
maintenance of the market value (plus accrued interest) of the collateral in
amounts at least equal to the repurchase price.

5. Futures Contracts

Securities or cash equal to the initial margin amount are either deposited with
the broker or segregated by the custodian upon entering into 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 made
or received 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 Fund records a realized gain or loss equal to the
difference between the proceeds from (or cost of ) the closing transactions and
the Fund's basis in the contract. The Fund enters into such contracts typically
to hedge a portion of its portfolio. The Fund bears the market risk that arises
from changes in the value of the financial instruments and securities indices
(futures contracts).

At December 31, 2003, the Fund had the following open futures contracts:

6. Option Contracts

Premiums paid when put or call options are purchased by the Fund represent
investments, which are marked-to-market daily and are included in the schedule
of investments. When a purchased option expires, the Fund will realize a loss
in the amount of the premium paid. When the Fund enters into a closing sales
transaction, the Fund 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 Fund exercises a put option, it 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 Fund exercises a call option, the cost of the security which the Fund
purchases upon exercise will be increased by the premium originally paid.

At December 31, 2003, the Fund held purchased put options with a total cost of
$46,766.

When a Fund writes a covered call or put option, an amount equal to the premium
received by the Fund is recorded as a liability, the value of which is
marked-to-market daily. When a written option expires, the Fund realizes a gain
equal to the amount of the premium received. When the Fund enters into a
closing purchase transaction, the Fund 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 a put option is exercised,
the amount of the premium originally received will reduce the cost of the
security which the Fund 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 Fund enters into options for hedging purposes. The risk in
writing a covered call option is that the Fund gives 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 Fund is exposed to
the risk of a loss if the market price of the underlying security declines. The
risk in writing a call option is that the Fund is exposed to the risk that the
market price of the underlying security increases.

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

The Fund may trade securities on a "to-be-announced" ("TBA") basis. In a TBA
transaction, the Fund 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 Fund, 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 December 31, 2003, the Fund held TBA securities with a cost of $109,588,438.

8. Mortgage Dollar Rolls
The Fund may enter into mortgage dollar roll transactions. A mortgage dollar
roll transaction involves a sale by the Fund of mortgage related securities
that it holds with an agreement by the Fund to repurchase similar securities at
an agreed upon price and date. The securities purchased will bear the same
interest rate as those sold, but generally will be collateralized by pools of
mortgages with different prepayment histories than those securities sold.
Proceeds from the sale will be reinvested and the income from these
investments, together with any additional income received on the sale, is
included in investment income. Losses may arise due to changes in the value of
the securities or if the counterparty does not perform under the terms of the
agreement. If the counterparty files for bankruptcy or becomes insolvent, the
Fund's right to repurchase the securities may be limited.

During the year ended December 31, 2003, the Fund entered into mortgage dollar
roll transactions in the aggregate amount of $1,605,508,477.

12.Capital Loss Carryforward

At December 31, 2003, the Fund had, for Federal income tax purposes,
approximately $68,039,000 of unused capital loss carryforwards available to
offset future capital gains. To the extent that these capital carryforward
losses are used to offset capital gains, it is probable that the gains so
offset will not be distributed.

The amount and year of expiration for each carryforward loss is indicated
below. Expiration occurs on December 31 of the year indicated:



                                    2006      2007        2008

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


In addition, the Fund had $567,103 of capital losses realized after October 31,
2003, which were deferred for Federal income tax purposes to the first day of
the following fiscal year.

13.Income Tax Information and Distributions to  Shareholders

The tax basis components of distributable earnings at December 31 were:



                                                  2003          2002

       Unrealized appreciation (depreciation)     (462,310)   30,228,638
       ------------------------------------------------------------------


At December 31, 2003, the difference between book basis and tax basis
unrealized appreciation and depreciation was attributable primarily to wash
sale loss deferrals, mark to market of derivative contracts and straddle loss
deferrals.

At December 31, 2002, the difference between book basis and tax basis
unrealized appreciation was attributable primarily to wash sale loss deferrals.

The tax character of distributions paid during the year ended December 31 was:

        22 Smith Barney Government Securities Fund | 2003 Annual Report





 NOTES TO FINANCIAL STATEMENTS (CONTINUED)


14.Additional Information

The Fund has received the following information from Citigroup Asset Management
("CAM"), the Citigroup business unit which includes the Fund's Investment
Manager and other investment advisory companies, all of which are indirect,
wholly-owned subsidiaries of Citigroup. CAM is reviewing its entry, through an
affiliate, into the transfer agent business in the period 1997-1999. As CAM
currently understands the facts, at the time CAM decided to enter the transfer
agent business, CAM sub-contracted for a period of five years certain of the
transfer agency services to a third party and also concluded a revenue
guarantee agreement with this sub-contractor providing that the sub-contractor
would guarantee certain benefits to CAM or its affiliates (the "Revenue
Guarantee Agreement"). In connection with the subsequent purchase of the
sub-contractor's business by an affiliate of the current sub-transfer agent
(PFPC Inc.) used by CAM on many of the funds it manages, this Revenue Guarantee
Agreement was amended eliminating those benefits in exchange for arrangements
that included a one-time payment from the sub-contractor.

The Boards of CAM-managed funds (the "Boards") were not informed of the Revenue
Guarantee Agreement with the sub-contractor at the time the Boards considered
and approved the transfer agent arrangements. Nor were the Boards informed of
the subsequent amendment to the Revenue Guarantee Agreement when that occurred.

CAM has begun to take corrective actions. CAM will pay to the applicable funds
approximately $17 million (plus interest) that CAM and its affiliates received
from the Revenue Guarantee Agreement and its amendment. CAM also plans an
independent review to verify that the transfer agency fees charged by CAM were
fairly priced as compared to competitive alternatives. CAM is instituting new
procedures and making changes designed to ensure no similar arrangements are
entered into in the future.

CAM has briefed the SEC, the New York State Attorney General and other
regulators with respect to this matter, as well as the U.S. Attorney who is
investigating the matter. CAM is cooperating with governmental authorities on
this matter, the ultimate outcome of which is not yet determinable.

15.Subsequent Event

Effective February 2, 2004, the 1.00% initial sales charge on Class L shares
will no longer be imposed.

 INDEPENDENT AUDITORS' REPORT

The Shareholders and Board of Directors of
Smith Barney Investment Funds Inc.:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of the Smith Barney Government Securities Fund of
Smith Barney Investment Funds Inc. ("Fund") as of December 31, 2003, and the
related statement of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended
and financial highlights for each of the years in the five-year period then
ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures
included confirmation of securities owned as of December 31, 2003, by
correspondence with the custodian and the broker. As to securities purchased,
but not yet received, we performed other appropriate auditing procedures. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Fund as of December 31, 2003, and the results of its operations for the year
then ended, the changes in its net assets for each of the years in the two-year
period then ended and its financial highlights for each of the years in the
five-year period then ended, in conformity with accounting principles generally
accepted in the United States of America.

               The Charter for the Audit Committee (the "Committee") of the
               Board of each registered investment company (the "Fund") advised
               by Smith Barney Fund Management LLC or Salomon Brothers Asset
               Management Inc. or one of their affiliates (each, an "Adviser")
               requires that the Committee shall approve (a) all audit and
               permissible non-audit services to be provided to the Fund and (b)
               all permissible non-audit services to be provided by the Fund's
               independent auditors to the Adviser and any Covered Service
               Providers if the engagement relates directly to the operations
               and financial reporting of the Fund. The Committee may implement
               policies and procedures by which such services are approved other
               than by the full Committee.

               The Committee shall not approve non-audit services that the
               Committee believes may impair the independence of the auditors.
               As of the date of the approval of this Audit Committee Charter,
               permissible non-audit services include any professional services
               (including tax services), that are not prohibited services as
               described below, provided to the Fund by the independent
               auditors, other than those provided to the Fund in connection
               with an audit or a review of the financial statements of the
               Fund. Permissible non-audit services may not include: (i)
               bookkeeping or other services related to the accounting records
               or financial statements of the Fund; (ii) financial information
               systems design and implementation; (iii) appraisal or valuation
               services, fairness opinions or contribution-in-kind reports; (iv)
               actuarial services; (v) internal audit outsourcing services; (vi)
               management functions or human resources; (vii) broker or dealer,
               investment adviser or investment banking services; (viii) legal
               services and expert services unrelated to the audit; and (ix) any
               other service the Public Company Accounting Oversight Board
               determines, by regulation, is impermissible.

               Pre-approval by the Committee of any permissible non-audit
               services is not required so long as: (i) the aggregate amount of
               all such permissible non-audit services provided to the Fund, the
               Adviser and any service providers controlling, controlled by or
               under common control with the Adviser that provide ongoing
               services to the Fund ("Covered Service Providers") constitutes
               not more than 5% of the total amount of revenues paid to the
               independent auditors during the fiscal year in which the
               permissible non-audit services are provided to (a) the Fund, (b)
               the Adviser and (c) any entity controlling, controlled by or
               under common control with the Adviser that provides ongoing
               services to the Fund during the fiscal year in which the services
               are provided that would have to be approved by the Committee;
               (ii) the permissible non-audit services were not recognized by
               the Fund at the time of the engagement to be non-audit services;
               and (iii) such services are promptly brought to the attention of
               the Committee and approved by the Committee (or its delegate(s))
               prior to the completion of the audit.

           (2)

        (f)    N/A

        (g)    Non-audit fees billed - $100,000 and $1.2 million for the years
               ended 12/31/2003 and 12/31/2002.

        (h)    Yes. The Smith Barney Investment Funds Inc. Audit Committee has
               considered whether the provision of non-audit services that were
               rendered to Service Affiliates which were not pre-approved (not
               requiring pre-approval) is compatible with maintaining the
               Accountant's independence. All services provided by the
               Accountant to Smith Barney Investment Funds Inc. or to Service
               Affiliates which were required to be pre-approved were pre-
               approved as required.

        (a)    The registrant's principal executive officer and principal

               effective as of a date within 90 days of the filing date of this
               report that includes the disclosure required by this paragraph,
               based on their evaluation of the disclosure controls and
               procedures required by Rule 30a-3(b) under the 1940 Act and
               15d-15(b) under the Securities Exchange Act of 1934.

        (b)    There were no changes in the registrant's internal control over
               financial reporting (as defined in Rule 30a-3(d) under the 1940
               Act) that occurred during the registrant's last fiscal half-year
               (the registrant's second fiscal half-year in the case of an
               annual report) that have materially affected, or are likely to
               materially affect the registrant's internal control over
               financial reporting.
