R. JAY GERKEN, CFA

Chairman, President and
Chief Executive Officer

Dear Shareholder,

Early this past summer bonds generally surrendered some of the gains they had
generated previously in 2003 due in part to signs of a sharp pick-up in the pace
of second-quarter economic growth. Despite subsequent reports of robust
third-quarter economic growth, comments from the Fed suggested to many investors
that it was likely to leave its interest rate targets at low levels for the
foreseeable future. As of the period's close, higher-rated corporate bonds
generally outperformed U.S. Treasury bonds with comparable maturities.

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

================================================================================
                                MANAGER OVERVIEW
================================================================================

Performance Review

For the 12 months ended December 31, 2003, Class A shares of the Smith Barney
Investment Grade Bond Fund, excluding sales charges, returned 5.22%. The fund's
Class A shares outperformed the fund's Lipper corporate debt funds A-rated
category average, which was 5.03% for the same period.(1) However, these shares
underperformed the fund's unmanaged benchmarks, the Lehman Brothers Long Term
Credit Bond Index(i) and Citigroup Credit Index 10+,(ii) which returned 10.81%
and 10.83%, respectively, for the same period. Over the period, corporate bonds
generally outperformed U.S. Treasuries with comparable maturities. We believe
the fund underperformed its unmanaged performance benchmarks, which are based
exclusively on the performance of corporate bonds, because during the reporting
period the fund held fixed-income instruments other than corporate bonds,
including U.S. government securities, to help preserve capital.

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 that gross domestic product ("GDP")(iii)
growth was stronger than expected, sparking concerns that inflation could pick
up. This led many investors to question whether the Fed's rate-cutting cycle had
run its course, which resulted in rising bond yields and a sharp decline in
prices over the summer.

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 shares 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 B shares returned -1.97%, Class L shares returned
- -1.87% and Class Y shares returned -1.46% for the six months ended December 31,
2003. Excluding sales charges, Class B shares returned 4.65%, Class L shares
returned 4.80% and Class Y shares returned 5.62% for the 12 months ended
December 31, 2003.

All index performance reflects no deductions for fees, expenses or taxes. The
Lehman Brothers Long-Term Credit Bond Index is a broad-based unmanaged index of
investment-grade corporate bonds. The Citigroup Credit Index 10+ is a

gains, if any, and excluding sales charges.

       2   Smith Barney Investment Grade Bond Fund | 2003 Annual Report


The decline was exacerbated due to selling from certain investors who held
mortgage-backed securities in their portfolios. Although Treasury notes and
bonds fluctuated significantly in July, the prices of shorter-term U.S.
Treasuries issues held up considerably better that month.

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. However, selling in the Treasury markets was more contained
than it was in July as we believe some of this economic growth was attributable
to one-time factors, such as the tax cuts and the end of major combat in Iraq,
and many analysts and investors felt that the Fed appeared to be in a holding
pattern.

According to estimates that were revised higher by the U.S. government later in
the quarter, real GDP increased 8.2% over the third quarter.(iv) Over the 12
months, corporate bonds (as well as mortgage-backed securities to a lesser
extent) generally outperformed U.S. Treasuries with similar maturities.

Portfolio Allocation Approach

Given our recent view of the economic environment, as of the period's close, we
maintained an overall shorter duration versus the benchmark index, as our goal
in this environment is to structure the portfolio focusing on sector allocation
and security selection while monitoring the movement in interest rates. We
continued to allocate investment capital primarily between corporate and
mortgage-backed fixed-income securities, as well as U.S. Treasuries, while
maintaining the ability to add exposure to other sectors when opportunities
arise.

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

Sincerely,


/s/ Gerald J. Culmone                  /s/ David A. Torchia

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

The definitions of the applicable rating symbols are set forth below:

Standard & Poor's Ratings Service ("Standard & Poor's") -- Ratings from "AA" to
"BB" 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 issues only in a small
       degree.
A   -- Bonds rated "A" have a strong capacity to pay interest and repay
       principal although they are 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  -- Bonds rated "BB" have less near-term vulnerability to default than other
       speculative issues. However, they face major ongoing uncertainties or
       exposure to adverse business, financial, or economic conditions which
       could lead to inadequate capacity to meet timely interest and principal
       payments.

Moody's Investors Service ("Moody's") -- Numerical modifiers 1, 2, and 3 may be
applied to each generic rating from "Aa" to "Baa", where 1 is the highest and 3
the lowest rating within its generic category.

Aaa -- Bonds 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 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 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 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.

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

       14  Smith Barney Investment Grade Bond Fund | 2003 Annual Report


================================================================================
Notes to Financial Statements
================================================================================

1. Significant Accounting Policies

Smith Barney Investment Grade Bond 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 Government
Securities Fund, Smith Barney Hansberger Global Value Fund, Smith Barney Small
Cap Value Fund, Smith Barney Small Cap Growth Fund, Smith Barney Group Spectrum
Fund, Smith Barney Multiple Discipline Funds -- Large Cap Growth and Value Fund
(formerly known as Smith Barney Premier Selections Large Cap Fund), Smith Barney
Multiple Discipline Funds -- All Cap Growth and Value Fund (formerly known as
Smith Barney Premier Selections All Cap Growth Fund) and Smith Barney Multiple
Discipline Funds -- Global All Cap Growth and Value Fund (formerly known as
Smith Barney Premier Selections Global Growth Fund). 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 prices were reported are valued at the mean between the bid and asked
prices; (c) securities for which market quotations are not available will be
valued in good faith at fair value by or under the direction of the Board of
Directors; (d) securities that have a maturity of more than 60 days are valued
at prices based on market quotations for securities of similar type, yield and
maturity; (e) securities maturing within 60 days are valued at cost plus
accreted discount, or minus amortized premium, which approximates value; (f)
dividend income is recorded on ex-dividend date and interest income, adjusted
for amortization of premium and accretion of discount, is recorded on an accrual
basis; (g) gains or losses on the sale of securities are calculated by using the
specific identification method; (h) 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; (i) class specific expenses are
charged to each class; management fees and general fund expenses are allocated
on the basis of relative net assets of each class or on another reasonable
basis; (j) the character of income and gains to be distributed is determined in
accordance with 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 capital accounts of the Fund to reflect
permanent book/tax differences and income and gains available for distributions
under income tax regulations. Net investment income, net realized loss and net
assets were not affected by this change; (k) 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; and (l) 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. 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 an annual rate of 0.45%
of the Fund's average daily net assets up to $500 million and 0.42% of the
Fund's average daily net assets thereafter. 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 up
to $500 million and 0.18% of the Fund's average daily net assets thereafter.
This fee is calculated daily and paid monthly.

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

Citicorp Trust Bank, fsb. ("CTB"), another subsidiary of Citigroup, acts as the
Fund's transfer agent. PFPC Inc. ("PFPC") and Primerica Shareholder Services
("PSS"), another subsidiary of Citigroup, 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. For
the year ended December 31, 2003, the Fund paid transfer agent fees of $351,009
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 4.50% and 1.00% for Class A and L
shares, respectively. There is a contingent deferred sales charge ("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 certain cases, 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 $1,625,000 and $225,000 on sales of the Fund's Class A
and L shares, respectively. In addition, CDSCs paid to CGM and its affiliates
were approximately:

                                     Class A           Class B           Class L

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 Fund requires continual
maintenance of the market value (plus accrued interest) of the collateral in
amounts at least equal to the repurchase price.

9. 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.

10. 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 Investment Grade Bond 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 broker. 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 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.

      (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 the 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
               financial officer have concluded that the registrant's disclosure
               controls and procedures (as defined in Rule 30a- 3(c) under the
               Investment Company Act of 1940, as amended (the "1940 Act")) are
               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.
