JAMES E. CONROY

Vice President and
Investment Officer

Dear Shareholder:

We are pleased to provide the semi-annual report for the Smith Barney Government
Securities Fund ("Portfolio") for the period ended June 30, 2000. In this
report, we summarize the period's prevailing economic and market conditions and
outline our portfolio strategy.1 A more detailed summary of performance can be
found in the appropriate sections that follow. We hope you find this report to
be useful and informative.

Performance Update
For the six months ended June 30, 2000, the Portfolio's Class A shares, without
and with sales charges, returned 3.89% and a negative 0.75%, respectively. In
comparison, the peer group average for general U.S. government funds posted a
return of 3.95% for the same period according to Lipper Inc. ("Lipper"). (Lipper
is an independent fund-tracking organization. The Portfolio's calculation of the
Lipper peer group average includes the reinvestment of all capital gains and
dividends without the effects of sales charges.) Also, the Lehman Brothers
Government Bond Index ("Lehman Index")2 returned 4.18% for the same period. In
addition, during the past six months, the Portfolio distributed income dividends
totaling $0.27 per Class A share. For additional performance information please
refer to pages six through eight.

The continued strength of the U.S. stock markets and the inverted yield curve
has made investing in bonds challenging. (The yield curve is a graphical
depiction of the relationship between the yield on bonds of the same credit
quality but different maturities. An inverted yield curve illustrates an
occurrence when shorter-term bonds have higher yields than longer-term bonds.)
However,it is our belief that the Federal Reserve Board's ("Fed") actions may
ultimately slow economic conditions and make bonds more appealing to many
investors over time. Additionally, we think that long-term rates may possibly
decline by the end of the year.

----------
1    The information provided represents the opinion of the manager and is not
     intended to be a forecast of future events, a guarantee of future results
     nor investment advice. Further, there is no assurance that certain
     securities will remain in or out of the Portfolio.

2    The Lehman Index is a broad-based unmanaged index of all U.S. government
     obligations. An investor cannot invest directly in an index.

Market Update and Outlook
In our view, the issues that significantly impacted the performance of the bond
market during the period were:

     . The increase in interest rates by the Fed;
     . The U.S. Treasury's buyback program;
     . Reduced mutual fund inflows; and
     . Investor concerns regarding credit quality, the extreme levels of market
       volatility and illiquidity.

The Fed raised interest rates three times for a total of 75 basis points3 during
the reporting period. In addition, the plan by the U.S. Treasury to buy back
more than $30 billion of its long-term debt obligations has led to reduced
supply in the market. As such, the price of longer-term bonds increased in
relation to their shorter-term counterparts, as reflected by an inverted yield
curve. Instead of a "normal" yield curve, with yields rising steadily along with
the maturity of Treasury bonds, the highest yields were for shorter-term bonds.

Investment Strategy & Portfolio Update4
The Portfolio seeks high current return and invests primarily in debt securities
issued or guaranteed by the U.S. government, its agencies or instrumentalities.
These securities include U.S. Treasury securities and mortgage-related
securities. Mortgage-related securities issued by federal agencies or
instrumentalities may be backed by the full faith and credit of the U.S.
Treasury, by the right of the issuer to borrow from the U.S. government or only
by the credit of the issuer itself. (Please note that the Portfolio's shares are
not guaranteed by the U.S. government or its agencies.)

During the period, the Portfolio's income orientation helped returns somewhat
due to our emphasis on mortgage-backed securities. We employed this strategy in
an attempt to mirror the 5-10 year U.S. Treasury benchmark. In addition, we have
maintained a duration of 4.5 to 6.5 years in the Portfolio during the period.

Our investment strategy has also included slowly buying U.S. Treasuries and
extending maturities as interest rates have continued to rise during the period.
In our view, we have probably seen the highs in yields over the near-term. Our
investment strategy in the coming months will be to increase our U.S. Treasury
exposure and reduce our mortgage-backed securities holdings as we believe rates
will continue to decline.

----------
3    A basis point is 0.01% or one one-hundredth of a percent.

4    Please note that the Portfolio's holdings are subject to change and any
     discussion of holdings is as of June 30, 2000. Please refer to page 11 for
     a complete list and percentage breakdown of the Portfolio's holdings.

We also avoided Federal Home Loan Mortgage Corporation ("Freddie Mac")5
obligations and Federal National Mortgage Association ("Fannie Mae")6
obligations during the period due to concerns regarding the future of federal
guarantees. Both the U.S. Treasury and Congress have questioned the rates that
these agencies receive versus corporations with similar balance sheets who for
the most part are required to finance their activities at higher interest rates.
These comments temporarily hurt the performance of Freddie Mac and Fannie Mae
securities, but benefited Government National Mortgage Association ("Ginnie
Mae")7 obligations. Many investors shifted their assets from Fannie Mae and
Freddie Mac securities, which are indirect obligations of the U.S. government,
to what they deemed to be the relative safe haven of Ginnie Mae securities,
which are direct obligations of the U.S. government.

The Portfolio's holdings of securities in the 8% to 81/2% coupon range during
the period were overweight versus its Lipper peer group. We believe that any
future decrease in interest rates may only benefit the Lipper average on a
short-term basis. As such, we are confident that our investment strategy should
benefit the Portfolio in times of rising and decreasing interest rates. (Of
course no guarantees can be given that our expectations will be met.)

As of June 30, 2000, the Portfolio's allocation was approximately 66% in
mortgage-backed securities, 21% in U.S. government obligations and 13% in
short-term instruments. And while no guarantees can be given, we believe our
strategy should continue to benefit the Portfolio.

The chart below shows the yields from U.S. Treasuries during the period under
review.

     Mortgage Corporation consisting of pooled mortgages backed by federal
     guarantees.

6    Fannie Mae obligations are securities offered by the Federal National
     Mortgage Association consisting of mortgages backed by the Federal Housing
     Administration and some non- governmentally backed mortgages.

7    Ginnie Mae obligations are securities backed by a pool of mortgages and
     guaranteed by the Government National Mortgage Association which passes
     through to investors the interest and principal payments to the bank or
     savings and loan that originated their mortgage.

(1)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value and does not reflect deduction of the applicable
     sales charges with respect to Class A and L shares or the applicable
     contingent deferred sales charges ("CDSC") with respect to Class B and L
     shares.
(2)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value. In addition, Class A and L shares reflect the
     deduction of the maximum initial sales charges of 4.50% and 1.00%,
     respectively. Class B shares reflect the deduction of a 4.50% CDSC, which
     applies if shares are redeemed within one year from purchase. This CDSC
     declines by 0.50% the first year after purchase and thereafter by 1.00% per
     year until no CDSC is incurred. Class L shares also reflect the deduction
     of a 1.00% CDSC, which applies if shares are redeemed within the first year
     of purchase.
*    Inception dates for Class A, B, L, Y and Z shares are November 6, 1992,
     March 20, 1984, February 4, 1993, February 7, 1996 and January 4, 1999,
     respectively.

+    Hypothetical illustration of $10,000 invested in Class B shares on June 30,
     1990, assuming reinvestment of dividends and capital gains, if any, at net
     asset value through June 30, 2000. The Lehman Brothers Government Bond
     Index is a broad-based index of all public debt obligations of the U.S.
     Government and its agencies and has an average maturity of approximately
     nine years. The Lipper General U.S. Government Peer Group Average is
     composed of the Portfolio's peer group of 189 mutual funds investing in
     U.S. Government securities as of June 30, 2000. The index is unmanaged and
     is not subject to the same management and trading expenses as a mutual
     fund. The performance of the Portfolio's other classes may be greater or
     less than the Class B shares' performance indicated on this chart,
     depending on whether greater or lesser sales charges and fees were incurred
     by shareholders investing in other classes.

     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. No adjustment
     has been made for shareholder tax liability on dividends or capital gains.

Portfolio Breakdown

                                    [GRAPH]

66.0% Mortgage-Backed Securities

20.9% U.S. Government and Agency Obligations

13.1% Repurchase Agreement

U.S. Government and Agency Obligations are obligations of, or guaranteed by, the
United States Government, its agencies or instrumentalities and include such
instruments as Treasury bills, notes and bonds.

Mortgage-Backed Securities are debt securities issued by the U.S. government
agencies such as the Federal Home Loan Mortgage Corporation (FHLMC), Federal
National Mortgage Association (FNMA) and Government National Mortgage
Association (GNMA). They represent thousands of individual home mortgages that
are pooled to form securities. As homeowners pay interest and principal each
month, these payments are passed on to investors. Mortgage-backed securities are
backed by the full faith and credit of the issuing agency.

1. Significant Accounting Policies

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

The significant accounting policies consistently 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 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 bid price, or in the absence of a recent bid price, at
the bid equivalent obtained from one or more of the major market makers; (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 accretion of original issue 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; (g) direct expenses are charged to each
portfolio and each class; management fees and general expenses are allocated on
the basis of the relative net assets; (h) 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; (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 December 31, 1999,
reclassifications were made to the Portfolio'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) 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

SSB Citi Fund Management LLC ("SSBC"), a subsidiary of Salomon Smith Barney
Holdings Inc. ("SSBH"), which, in turn, is a subsidiary of Citigroup Inc.
("Citigroup"), acts as investment advisor to the Portfolio. The Portfolio pays
SSBC an advisory fee calculated at the following annual rates of average daily
net assets: 0.35% up to $2 billion, 0.30% of the next $2 billion, 0.25% of the
next $2 billion, 0.20% of the next $2 billion and then 0.15% of the remaining
average daily net assets. This fee is calculated daily and paid monthly.

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

Citi Fiduciary Trust Company ("CFTC"), formerly known as Smith Barney Private
Trust Company, another subsidiary of Citigroup, acts as the Portfolio's transfer
agent and PFPC Global Fund Services ("PFPC") acts as the Portfolio's
sub-transfer agent. CFTC receives account fees and asset-based fees that vary
according to the account size and type of account. PFPC is responsible for
shareholder recordkeeping and financial processing for all shareholder accounts
and is paid by CFTC. During the six months ended June 30, 2000, the Portfolio
paid transfer agent fees of $132,204 to CFTC.

Effective June 5, 2000, Salomon Smith Barney Inc. ("SSB"), another subsidiary of
SSBH, became the Portfolio's distributor replacing CFBDS, Inc. ("CFBDS"). In
addition, SSB acts as the primary broker for the Fund's portfolio agency
transactions. Certain other broker-dealers, continue to sell Portfolio shares to
the public as members of the selling group.

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. This CDSC declines by 0.50% the first year after purchase 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 the first year of
purchase. In addition, Class A shares have a 1.00% CDSC, which applies if
redemption occurs within the first year of purchase. 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.

Notes to Financial Statements (unaudited)(continued)
--------------------------------------------------------------------------------
For the six months ended June 30, 2000, CFBDS and SSB received sales charges of
approximately $39,000 and $16,000 on sales of the Portfolio's Class A and L
shares, respectively. In addition, CDSCs paid to SSB were approximately $81,000
for Class B shares.

Pursuant to a Distribution Plan, the Portfolio pays a service fee with respect
to Class A, B and L shares calculated at the annual rate of 0.25% of the average
daily net assets for each respective class. The Portfolio also pays a
distribution fee with respect to Class B and L shares calculated at the annual
rate of 0.50% and 0.45% of the average daily net assets for each class,
respectively. For the six months ended June 30, 2000, total Distribution Plan
fees incurred were:

                                            Class A        Class B      Class L
================================================================================
Distribution Plan Fees                      $345,406       $213,858     $22,040
================================================================================

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

3. Investments

During the six months ended June 30, 2000, the aggregate cost of purchases and
proceeds from sales of investments (including maturities, but excluding
short-term securities) were as follows:

================================================================================
Purchases                                                          $820,315,743
--------------------------------------------------------------------------------
Sales                                                               892,062,362
================================================================================

At June 30, 2000, aggregate gross unrealized appreciation and depreciation of
investments for Federal income tax purposes were substantially as follows:

================================================================================
Gross unrealized appreciation                                        $5,106,344
Gross unrealized depreciation                                        (1,393,645)
--------------------------------------------------------------------------------
Net unrealized appreciation                                          $3,712,699

4. Capital Loss Carryforward

At December 31, 1999, the Portfolio had, for Federal tax purposes, approximately
$75,237,000 of unused capital loss carryforwards available to offset future
capital gains. 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 amount and expiration of the carryforwards are indicated below. Expiration
occurs on December 31 of the year indicated:

                                          2002           2003           2007
================================================================================
Capital Loss Carryforward               $31,677,000    $195,000      $43,365,000
================================================================================

5. Repurchase Agreements

The Portfolio purchases (and its 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 Portfolio requires continual
maintenance of the market value of the collateral in amounts at least equal to
the repurchase price.

6. Reverse Repurchase Agreements

The Portfolio may enter into reverse repurchase agreement transactions for
leveraging purposes. A reverse repurchase agreement involves a sale by the
Portfolio of securities that it holds with an agreement by the Portfolio 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 the Portfolio may decline below the repurchase price of the securities.
The Portfolio will establish a segregated account with its custodian, in which
the Portfolio 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.

During the six months ended June 30, 2000, the Portfolio did not enter into any
reverse repurchase agreements.

<PAGE>

--------------------------------------------------------------------------------
Notes to Financial Statements (unaudited)(continued)
--------------------------------------------------------------------------------
7. Futures Contracts

Initial margin deposits made upon entering into futures contracts are recognized
as assets. The initial margin is segregated by the custodian and is noted in the
schedule of investments. 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 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.

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 June 30, 2000, the Portfolio had no open futures contracts.

8.  Options Contracts

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

At June 30, 2000, the Portfolio had no purchased call or put options.

When a Portfolio writes a covered call or put 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 a put option is
exercised, the amount of the premium originally received will reduce the cost of
the security which the Portfolio 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 Portfolio enters into options for hedging purposes. 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. The risk in writing a put option is that the Portfolio is
exposed to the risk of a loss if the market price of the underlying security
declines.

During the six months ended June 30, 2000, the Portfolio did not write any call
or put option contracts.

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

The Portfolio may trade securities on a "to-be-announced" ("TBA") basis. 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 June 30, 2000, the Portfolio did not hold any TBA securities.

10.  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,and receives a lenders fee. Fees earned by the Portfolio on
securities lending are recorded in 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. The Fund maintains
exposure for the risk of any losses in the investment of amounts received as
collateral.

At June 30, 2000, the Portfolio had no securities on loan.

FUND HIGHLIGHT
--------------------------------------------------------------------------------

Strict adherence to our approach of investing in companies with positive
earnings characteristics and reasonable stock valuations continued to drive the
Fund's performance results during the period. In addition, sticking to our
investment philosophy of being fully invested enabled the Fund to capture higher
returns from stocks versus the yields from either bonds or cash equivalents.

Performance Update

For the six months ended June 30, 2000, the Fund's Class A shares reported
negative total returns of 5.25% and 0.24%, with and without sales charges,
respectively. In comparison, the Standard & Poor's 500 Index ("S&P 500")
returned negative 0.43% and the Russell 1000 Growth Index returned 4.23% for the
same period.1

Investment Strategy and Portfolio Update

In our inaugural report to shareholders two years ago, we stated that we are
active managers. We have specific criteria that we look for in every company
that we invest in. As long as a particular holding meets our criteria, it will
remain in the Fund's portfolio. When that criteria is no longer met, the
security is sold and replaced with one that meets our strict parameters.

We are also bottom-up2 managers who strive to remain fully invested at all
times. We seek to identify companies that we believe may provide the best
returns to our shareholders over time, while at the same time trying to help
minimize risk.

Strict adherence to our approach of investing in companies with positive
earnings characteristics and reasonable stock valuations continued to influence
the Fund's performance results during the period.

Market and Portfolio Outlook3

The first six months of this year can be characterized as two periods. For the
first three months, your Fund was appreciating more rapidly than the market.
Such performance was the result of favorable stock selection and emphasizing
sectors of the market that were performing well. Specifically, our investments
in technology stocks like LSI Logic, Apple Computer and Applied Material
performed well. In the telecommunications sector, Nextel was a positive
performer. Also, our investments in healthcare stocks were rewarded with
favorable performance results.

The period April through June can best be described as one when your Fund was
not holding up well in a declining market, specifically during the month of May.
Most stocks in the portfolio contributed to the decline during the period,
regardless of the area of the market each stock was associated with.

The net result is that both the portfolio and the market experienced a
considerable amount of volatility, but basically did not perform well for the
first

1    The S&P 500 is a market capitalization-weighted measure of 500 widely held
     common stocks. The Russell 1000 Growth Index contains those securities in
     the underlying indexes with higher price-to-book ratios and higher
     forecasted growth ratios. An investor cannot invest directly in an index.

2    Bottom-up approach investing is to search for outstanding performance of
     individual stocks before considering the impact of economic trends.

3    Please note the Fund's holdings are subject to change and any discussion of
     the holdings is as of June 30, 2000. Please refer to pages 7 through 9 for
     a complete list and percentage breakdown of the Fund's holdings.

six months of the year. The beginning of the year witnessed the lack of validity
of Y2K concerns. It also was a period where economic activity and corporate
profit growth was solid. The second quarter can be best described as a period
where investors experienced elevated concerns about the impact of rising
interest rates on the economy and corporate profits. It also contained
considerable rotation within stock groups by investors, causing significant
fluctuations in individual stock prices. While we do not disregard the negative
impact rising interest rates may have on stock valuations, we think the
directional bias for the market should be up for the remainder of the year.

Generally, the Fund invests in companies where business trends are good, current
earnings characteristics and visibility are positive, and stock valuations are
deemed to be reasonable. We expect these specific companies and those with
similar traits to be rewarded with above-average results for the remainder of
the year. We continue to find a reasonable number of companies with these
characteristics to invest in. Many continue to be in technology, consumer
cyclical, utility and capital goods sectors of the market. General Electric,
Analog Devices, Pharmacia and Tyco International are examples of stocks that
currently fit our criteria. We continue to evaluate and monitor companies in the
financial, consumer staples and oil service sectors of the market for possible
investment opportunities. Finally, attention to earnings and valuation risks
deserves a premium in the current market environment. We seek to continue to
sell aggressively those companies that violate our sell discipline for either
fundamental or valuation reasons. This year, the market may be rewarding stock
selection.

Thank you for your investment in the Concert Peachtree Growth Fund. We look
forward to serving your investment needs in the future.

Respectfully submitted,

(1)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value and does not reflect the deduction of the
     applicable sales charges with respect to Class A and L shares or the
     applicable contingent deferred sales charges ("CDSC") with respect to Class
     B and L shares.

(2)  Performance calculations for Class A and B shares include the historical
     return information related to the Common Sense II Aggressive Opportunity
     Fund of the Common Sense Trust, which was the predecessor fund, for the
     period from May 3, 1994 through June 30, 1995.

(3)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value. In addition, Class A and Class L shares reflect
     the deduction of the maximum initial sales charge of 5.00% and 1.00%,
     respectively; Class B shares reflect the deduction of a 5.00% CDSC, which
     applies if shares are redeemed within one year from purchase. Thereafter,
     the CDSC declines by 1.00% per year until no CDSC is incurred. Class L
     shares also reflect the deduction of a 1.00% CDSC, which applies if shares
     are redeemed within the first year of purchase.

*    Inception dates for Class A, B, L and Y shares are July 3, 1995, July 3,
     1995, August 8, 1995 and October 15, 1997, respectively.

+    Total return is not annualized, as it may not be representative of the
     total return for the year.

+ Hypothetical illustration of $10,000 invested in Class A and B shares on May
  3, 1994 (inception of Common Sense II Aggressive Opportunity Fund of the
  Common Sense Trust ("Common Sense") which was the predecessor Fund), assuming
  deduction of the maximum 5.00% sales charge at the time of investment for
  Class A shares and reinvestment of dividends and capital gain, if any, at net
  asset value through June 30, 2000. (Performance calculations include the
  historical return information related to Common Sense for the period from May
  3, 1994 through June 30, 1995). The Russell 2000 Index is composed of the
  2,000 smallest companies in the Russell 3000 Index. The Russell 3000 Index is
  composed of 3,000 of the largest U.S. companies by market capitalization. The
  Russell 1000 Index measures the performance of the 1,000 largest companies in
  the Russell 3000 Index. The Russell 1000 Growth Index measures the performance
  of those Russell 1000 companies with higher price-to-book ratios and higher
  forecasted growth values. The indexes are unmanaged and are not subject to the
  same management and trading expenses as a mutual fund. An investor may not
  invest directly in an index. The performance of the Fund's other classes may
  be greater or less than the Class A and B shares' performance indicated on
  this chart, depending on whether greater or lesser sales charges and fees were
  incurred by shareholders investing in other classes.

  All figures represent past performance and are not a guarantee of future
  results. Investment returns and principal value will fluctuate, and redemption
  values may be more or less than the original cost. No adjustment has been made
  for shareholder tax liability on dividends or capital gains.

1. Significant Accounting Policies

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

The significant accounting policies consistently 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 price on such markets;
securities traded in the over-the-counter market and listed securities for which
no sales price were reported are valued at bid price, or in the absence of a
recent bid price, at the bid equivalent obtained from one or more of the major
market makers; (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, other than U.S. government agencies, 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 is recorded on an accrual basis; (g)
dividends and distributions to shareholders are recorded on the ex-dividend
date; (h) gains or losses on the sale of securities are calculated using the
specific identification method; (i) the accounting records are maintained in
U.S. dollars. All assets and liabilities denominated in foreign currencies are
translated into 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; (j) direct expenses are charged to each class;
management fees and general portfolio expenses are allocated on the basis of
relative net assets; (k) 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;
(l) the character of income and gains distributed are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles. At December 31, 1999, reclassifications were made to the Portfolio'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 (m)
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 Other Transactions

SSB Citi Fund Management LLC ("SSBC"), a subsidiary of Salomon Smith Barney
Holdings Inc. ("SSBH"), which in turn, is a subsidiary of Citigroup Inc.
("Citigroup"), acts as investment manager of the Fund. The Portfolio pays SSBC a
management fee calculated at an annual rate of 1.00% of the average daily net
assets up to $250 million and 0.85% of the average daily net assets in excess of
$250 million. This fee is calculated daily and paid monthly.

Citi Fiduciary Trust Company ("CFTC"), formerly known as Smith Barney Private
Trust Company, another subsidiary of Citigroup, acts as the Fund's transfer
agent and PFPC Global Fund Services ("PFPC") acts as the sub-transfer agent.
CFTC receives account fees and asset-based fees that vary according to the
account size and type of account. PFPC is responsible for shareholder
recordkeeping and financial processing for all shareholder accounts and are paid
by CFTC. During the six months ended June 30, 2000, the Portfolio paid transfer
agent fees of $5,541 to CFTC.

Effective June 5, 2000, Salomon Smith Barney Inc. ("SSB"), another subsidiary of
SSBH, became the Fund's distributor replacing CFBDS, Inc. ("CFBDS"). In
addition, SSB acts as the primary broker for the Fund's portfolio agency
transactions. Certain other broker-dealers continue to sell Fund shares to the
public as members of the selling group. For the six months ended June 30, 2000,
SSB and its affiliates did not receive brokerage commissions.

There are maximum initial sales charges of 5.00% and 1.00% for Class A and L
shares, respectively. There is a contingent deferred sales charge ("CDSC") of
5.00% on Class B shares, which applies if redemption occurs within one year from
initial purchase and declines thereafter by 1.00% per year until no CSDC is
incurred. Class L shares also have a 1.00% CDSC, which applies if redemption
occurs within the first year of purchase. In addition, Class A shares also have
a 1.00% CDSC, which applies if redemption occurs within the first year of
purchase. 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 six months ended June 30, 2000, CFBDS and SSB received sales charges of
approximately $49,000 and $1,000 for Class A and Class L shares, respectively.
In addition, CDSCs paid to SSB were approximately $3,000 for Class B shares.

Pursuant to a Distribution Plan, the Portfolio pays a service fee with respect
to Class A, B and L shares calculated at the annual rate of 0.25% of the average
daily net assets for each respective class. The Portfolio also pays a
distribution fee with respect to Class B and L shares calculated at an annual
rate of 0.75% of the average daily net assets of each class.

For the six months ended June 30, 2000, total Distribution Plan fees incurred by
the Portfolio were:

                                   Class A            Class B            Class L
================================================================================
Distribution Plan Fees             $156,810           $492,949            $3,386
================================================================================

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

3. Investments

During the six months ended June 30, 2000, the aggregate cost of purchases and
proceeds from sales of investments (including maturities, but excluding
short-term securities) were as follows:

================================================================================
Purchases                                                          $307,351,841
--------------------------------------------------------------------------------
Sales                                                               293,955,163
================================================================================

At June 30, 2000, the aggregate gross unrealized appreciation and depreciation
of investments for Federal income tax purposes were substantially as follows:

================================================================================
Gross unrealized appreciation                                      $ 64,742,940

4. Repurchase Agreements

The Portfolio purchases (and its 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 Portfolio requires continual
maintenance of the market value of the collateral in amounts at least equal to
the repurchase price.

5. Option Contracts

Premiums paid when put or call options are purchased by the Portfolio, represent
investments, which are marked-to-market daily. When a purchased option expires,
the Portfolio will realize a loss in the amount of the premium paid. When the
Portfolio enters into a closing sales transaction, the Portfolio will realize a
gain or loss depending on whether the sales proceeds from the closing sales
transaction are greater or less than the premium paid for the option. When the
Portfolio 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 Portfolio exercises a call option, the
cost of the security which the Portfolio purchases upon exercise will be
increased by the premium originally paid.

At June 30, 2000, the Portfolio had no purchased call or put options.

When a Portfolio writes a covered call or put 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 a written put
option is exercised, the amount of the premium originally received will reduce
the cost of the security which the Portfolio purchased upon exercise. When a
written index option is exercised, settlement is made in cash. The risk
associated with purchasing options is limited to the premium originally paid.
The Portfolio enters into options for hedging purposes. 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. The risk in writing a put option is that the Portfolio is
exposed to the risk of loss if the market price of the underlying security
declines.

During the six months ended June 30, 2000, the Portfolio did not write any call
or put option contracts.

6. 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. The Portfolio maintains exposure for the
risk of any losses in the investment of amounts received as collateral.

expenses, including those specifically related to the distribution of its
shares.

      any, at net asset value and does not reflect the deduction of the
      applicable sales charges with respect to Class A and L shares or the

      Class B and L shares.

(2)   Assumes reinvestment of all dividends and capital gain distributions, if
      any, at net asset value. In addition, Class A and L shares reflect the
      deduction of the maximum initial sales charge of 4.50% and 1.00%,
      respectively; and Class B shares reflect the deduction of a 4.50% CDSC,
      which applies if shares are redeemed within one year from purchase. This
      CDSC declines by 0.50% the first year after purchase and thereafter by
      1.00% per year until no CDSC is incurred. Class L shares also reflect the
      deduction of a 1.00% CDSC, which applies if shares are redeemed within the
      first year of purchase.

      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.

+     Total return is not annualized, as it may not be representative of the
      total return for the year.

++    Inception dates for Class A, B and L shares are November 6, 1992, January
      4, 1982 and February 26, 1993, respectively.

FUND HIGHLIGHT
================================================================================

During the period covered by this report, our strategy included slowly buying
longer-dated U.S. Treasuries and extending maturities as interest rates rose
during the period. Due to the U.S. Treasury's plan to buy back more than $30
billion of long-term debt, we anticipate that interest rates on the long end of
the yield curve will continue to be lower than rates on the short end of the
yield curve. (Of course, no guarantees can be given that our expectations will
be met.)

James E.
Conroy

Vice President and
Investment Officer

Dear Shareholder:

We are pleased to provide the semi-annual report for the Smith Barney Investment
Grade Bond Fund ("Portfolio") for the period ended June 30, 2000. In this
report, we summarize the period's prevailing economic and market conditions and
outline our investment strategy.(1) A more detailed summary of performance can
be found in the appropriate sections that follow. We hope you find this report
to be useful and informative.

Performance Update(2)

For the six months ended June 30, 2000, the Portfolio's Class A shares, without
sales charges, returned 3.58%. The Portfolio's Class A shares, with sales
charges, returned a negative 1.09%. In comparison, the Salomon Smith Barney
Corporate Index 10+ ("SSB Index")(3) returned 1.92% for the same time period.

In addition, during the past six months, the Portfolio distributed income
dividends totaling $0.35 per Class A share. For additional performance
information please refer to pages four through six.

Market Update and Outlook

In our view, the issues that significantly impacted the performance of the bond
market during the period were:

o     The increase in interest rates by the Federal Reserve Board ("Fed");

o     The U.S. Treasury's buyback program;

o     Reduced mutual fund inflows; and

o     Investor concerns regarding credit quality, the extreme levels of market
      volatility and illiquidity.

The Fed raised interest rates three times for a total of 75 basis points(4)
during the reporting period. In addition, the plan by the U.S. Treasury to buy
back more than $30 billion of its long-term debt obligations has led to reduced
supply in the market. As such, the price of longer-term bonds increased in
relation to their shorter-term counterparts, as reflected by an inverted yield
curve. Instead of a "normal" yield curve, with yields rising steadily along with
the maturity of Treasury bonds, the highest yields were for shorter-term bonds.

During the period covered by this report, our strategy included slowly buying
longer-dated U.S. Treasuries and extending maturities as interest rates rose
during the period. Due to the U.S. Treasury's buyback program, we anticipate
that interest rates on the long end of the yield curve will continue to be lower
than rates on the short end of the yield curve. (Of course, no guarantees can be
given that our expectations will be met.)

Investment Strategy

The Portfolio seeks as high a level of current income as is consistent with
prudent investment management and preservation of capital by investing primarily
in "investment grade" fixed-income securities. Investment grade securities are
securities rated by a national ratings organization (e.g., Moody's Investors
Service, Inc. or Standard & Poor's Ratings Service) within one of the top four
catagories, or, if unrated, judged by the manager to be of comparable credit
quality. The Portfolio may also invest in U.S. government securities and U.S.
dollar-denominated fixed-income securities of foreign issuers. The Portfolio may
invest in securities of any maturity.

1     The information provided represents the opinion of the manager and is not
      intended to be a forecast of future events, a guarantee of future results
      nor investment advice. Further, there is no assurance that certain
      securities will remain in or out of the Portfolio.
2     Please note that the Portfolio's holdings are subject to change and any
      discussion of holdings is as of June 30, 2000. Please refer to pages eight
      through ten for a complete list and percentage breakdown of the
      Portfolio's holdings.
3     The SSB Index is a broad-based unmanaged index of investment grade
      corporate bonds with maturities of ten years or more. Please note that an
      investor cannot invest directly in an index.
4     A basis point is 0.01% or one one-hundredth of a percent.

2                                        2000 Semi-Annual Report to Shareholders
<PAGE>

We continue to emphasize individual bond selection while diversifying the
Portfolio's investments across a range of issues, industries and maturity dates.
In selecting individual corporate bonds for investment, we:

o     Use fundamental credit analysis to estimate the relative value and
      attractiveness of various companies and bond issues;

o     Seek to identify undervalued corporate bond issues and avoid issues that
      may be subject to credit downgrades; and

o     Determine sector and maturity weightings based on intermediate and
      long-term assessments of the economic environment and interest rate
      outlook.

Additionally, going forward, we will look to lengthen the Portfolio's duration
and identify those securities that we deem as appropriate investments.

The chart below shows the yields from U.S. Treasuries during the period under
review.

century.

(1)   Assumes reinvestment of all dividends and capital gain distributions, if
      any, at net asset value and does not reflect the deduction of the
      applicable sales charges with respect to Class A and L shares or the
      applicable contingent deferred sales charges ("CDSC") with respect to
      Class B and L shares.
(2)   Assumes reinvestment of all dividends and capital gain distributions, if
      any, at net asset value. In addition, Class A and L shares reflect the
      deduction of the maximum initial sales charge of 4.50% and 1.00%,
      respectively; Class B shares reflect the deduction of a 4.50% CDSC, which
      applies if shares are redeemed within one year from initial purchase. This
      CDSC declines by 0.50% the first year after purchase and thereafter by
      1.00% per year until no CDSC is incurred. Class L shares also reflect the
      deduction of a 1.00% CDSC, which applies if shares are redeemed within the
      first year of purchase.
*     Inception dates for Class A, B, L and Y shares are November 6, 1992,
      January 4, 1982, February 26, 1993 and February 7, 1996, respectively.

+     Hypothetical illustration of $10,000 invested in Class B shares on June
      30, 1990, assuming reinvestment of dividends and capital gains, if any, at
      net asset value through June 30, 2000. The Salomon Smith Barney Corporate
      Index 10+ is a broad-based unmanaged index of investment grade corporate
      bonds with maturities of ten years or more. The Index is unmanaged and is
      not subject to the same management and trading expenses as a mutual fund.
      The Lipper Corporate Debt A-Rated Average is composed of the Portfolio's
      peer group of 179 mutual funds as of June 30, 2000. The performance of the
      Portfolio's other classes may be greater or less than the Class B shares'
      performance indicated on this chart, depending on whether greater or
      lesser sales charges and fees were incurred by shareholders investing in
      the other classes.

      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. No adjustment
      has been made for shareholder tax liability on dividends or capital gains.

================================================================================
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, Inc. ("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.

Notes to Financial Statements (unaudited)

1. Significant Accounting Policies

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

The significant accounting policies consistently 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 price on such markets;
securities for which no sales price were reported are valued at bid price, or in
the absence of a recent bid price, at the bid equivalent obtained from one or
more of the major market makers; (c) 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; (d) securities maturing within 60 days are
valued at cost plus accreted discount, or minus amortized premium, which
approximates value; (e) dividend income is recorded on ex-dividend date and
interest income 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) direct expenses are charged to each class; management fees and general
portfolio expenses are allocated on the basis of relative net assets; (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; (j) 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
December 31, 1999, reclassifications were made to the Portfolio'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 (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. Investment Advisory Agreement, Administration Agreement and Other
Transactions

SSB Citi Fund Management LLC ("SSBC"), a subsidiary of Salomon Smith Barney
Holdings Inc. ("SSBH"), which, in turn, is a subsidiary of Citigroup Inc.
("Citigroup") acts as investment adviser to the Portfolio. The Portfolio pays
SSBC an advisory fee calculated at an annual rate of 0.45% of the average daily
net assets up to $500 million and 0.42% of the average daily net assets
thereafter. This fee is calculated daily and paid monthly.

Citi Fiduciary Trust Company ("CFTC"), formerly known as Smith Barney Private
Trust Company, another subsidiary of Citigroup, acts as the Portfolio's transfer
agent and PFPC Global Fund Services ("PFPC") acts as the Portfolio's
sub-transfer agent. CFTC receives account fees and asset-based fees that

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

vary according to the account size and type of account. PFPC is responsible for
shareholder recordkeeping and financial processing for all shareholder accounts
and is paid by CFTC. For the six months ended June 30, 2000, the Portfolio paid
transfer agent fees of $139,638 to CFTC.

SSBC also acts as the Portfolio's administrator for which the Portfolio pays a
fee calculated at an annual rate of 0.20% of the average daily net assets up to
$500 million and 0.18% of the average daily net assets thereafter. This fee is
calculated daily and paid monthly.

Effective June 5, 2000, Salomon Smith Barney Inc. ("SSB"), another subsidiary of
SSBH, became the Portfolio's distributor replacing CFBDS, Inc. ("CFBDS"). In
addition, SSB acts as the primary broker for the Portfolio's agency
transactions. Certain other broker-dealers, continue to sell Portfolio shares to
the public as members of the selling group.

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. This CDSC declines by 0.50% the first year after purchase 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 the first year of
purchase. In certain cases, Class A shares have a 1.00% CDSC, which applies if
redemption occurs within the first year of purchase. 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 six months ended June 30, 2000, SSB and CFBDS received sales charges of
approximately $72,000 and $14,000 on sales of the Portfolio's Class A and L
shares, respectively. In addition, CDSCs paid to SSB were approximately:

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

Pursuant to a Distribution Plan, the Portfolio pays a service fee with respect

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
in 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. The Portfolio maintains exposure for the
risk of any losses in the investment of amounts received as collateral.
