FUND HIGHLIGHT
- --------------------------------------------------------------------------------
Our investment strategy is designed to provide our shareholders with the
potential for upside stock market participation, a competitive stream of income
and downside protection. The way we accomplish our strategy is to combine
equities (stocks and convertibles) with bonds and stock market index exposure
(S&P Index futures and options). The bonds provide most of the income while the
stocks should provide long-term appreciation. The Index exposure assures that
the Fund will participate with the market, in both directions, even if our
quality investment approach is temporarily out of favor.

HEATH B. MCLENDON            ROSS MARGOLIES

Chairman                     Investment Officer


Dear Shareholder:

We are pleased to present the annual report for the Smith Barney Premium Total
Return ("Fund") for the year ended December 31, 1999. In this report, we discuss
stock market conditions and review our investment strategy during the reporting
period. A more detailed summary of performance and current holdings can be found
in the appropriate sections that follow. Any discussion of the Fund's holdings
is as of December 31, 1999. Please refer to pages nine through twenty for a list
of the Fund's holdings. We hope you find this report to be informative and
useful.


Performance Overview
For the year ended December 31, 1999 the Fund provided a total return of 5.37%
for its Class A shares, excluding the effects of sales charges. During this same
period, the U.S. stock market, as measured by the Standard and Poor's 500 Index
("S&P 500"), had a total return of 21.03%. (The S&P 500 is a market
capitalization-weighted measure of 500 widely held common stocks.)

The Fund's relative performance has improved over the past year.* We believe
that our new investment strategy, which is described in greater detail later on
in this letter, has contributed significantly to the Fund's performance relative
to the market. (Of course, past performance is not indicative of future
results.) For the period from May 1, 1999 through December 31, 1999 the Fund's
Class A shares returned 5.95%, excluding the effects of sales charges, versus
10.04% for the S&P 500.** Additional Fund performance information can be found
beginning on page five.

Investment Strategy
The Fund's investment strategy is designed to capture as much as possible of the
stock market's long-term appreciation potential while at the same time seeking
to pay a regular monthly income dividend and having substantially lower
potential volatility than the overall stock market. Another way to view the
Fund's strategy is that our goal is to generate a compound annual return at or
around that of the S&P 500 over an entire market cycle that includes both a bull
and bear market. (Of course, no guarantees can be made that our goal will be
met.)

At the same time, because the Fund assumes less risk than the overall stock
market, its annual volatility (i.e., a measure of risk) should be substantially
lower than that of the S&P 500. (Again, no assurances can be made that the Fund
will in fact have lower volatility than the S&P 500.) Over shorter periods of
time such as one year, we expect that the Fund should post a

- ----------
*    Ross S. Margolies, a Managing Director and Co-Chief Investment Officer of
     Salomon Brothers Asset Management Inc., ("SaBAM"), and his investment team
     were designated portfolio managers of the Fund on April 26, 1999. On June
     30, 1999, the shareholders of the Fund approved a new sub-investment
     advisory agreement ("Agreement") with SaBAM. The Agreement will be in
     effect for an initial two-year period ending June 30, 2001, and may
     continue thereafter from year to year only if specifically approved at
     least annually by the Board of Trustees or by a vote of a majority of the
     outstanding voting shares of the Fund, and in either event, the vote of a
     majority of the non-interested Trustees. The Fund's investment objective --
     total return consisting of long-term capital appreciation and income --
     remains unchanged.

**   Please note that the Fund's Class A shares returned 0.65% with sales
     charges over the same time period. Moreover, the Fund's average annual
     total returns were 0.08%, 14.47% and 12.70%, with sales charges,
     respectively, for the one-year period ended December 31, 1999, five-year
     period ended December 31, 1999 and from inception (11/6/92) through
     December 31, 1999.

total return (including dividends) of more than 75% of the S&P 500's during up
markets and participate in less than 75% of the stock market's decline during
down years. We believe that these three Fund attributes (the potential for
upside participation, competitive monthly income and potential protection) are
appropriate based on the risk and reward profiles of our shareholders.

Our core investment style is centered on a bottom-up stock picking*** strategy.
We focus on thoroughly understanding a company's business, its strategy,
competitive position and industry. Our seasoned financial analysis pays close
attention to a company's resources to meet its goals and the consistency of the
numbers to determine their quality (e.g., are receivables growing much faster
than sales, a sign that current sales may overstate a long-term trend).
Moreover, we carefully analyze the numbers to create a framework to ascertain a
stock's valuation and risk. These and other factors are then weighed before we
make a final judgement. If all of these factors lead us to conclude that the
risk and reward trade-off of a particular security is favorable, we will then
invest.

Our portfolio is designed to meet a strict set of investment objectives. We use
tools such as diversification, position weighting and asset allocation to
determine exactly how much of each security to own in the portfolio. For
instance, in the Fund, not only do our best ideas get higher weightings, our
higher risk ideas get lower weightings. We also try to make sure that the Fund's
portfolio has some exposure to important growing parts of the economy such as
technology, telecommunications, healthcare, financials and consumer.

As mentioned previously, the Fund's investment strategy is designed to provide
our shareholders with the potential for some upside participation, a competitive
stream of income and downside protection. The way we accomplish our strategy is
to combine equities (i.e., stocks and convertibles) with bonds and stock market
index exposure (i.e., S&P 500 futures and options).

The bonds provide most of the income while the stocks should provide long-term
appreciation potential based on our bottom-up stock selection process. In our
view, the index exposure assures that the Fund will participate with the stock
market, in both directions, even if our equity investment approach is
temporarily out of favor.

As you may remember, before our designation as managers, the Fund relied on a
deep value investment strategy. This style has been out of favor in recent years
and led the previous investment team to have virtually no exposure to the
fast-growing technology sector. While value strategies may be viable over the
long term, both pure value and pure growth strategies are susceptible to
significant periods of being out of favor with the market. We believe that our
blend approach to the stock and index portions of the Fund's portfolio assures
some stock market participation under most conditions.

In addition to our core investment strategy that seeks low volatility, we
regularly buy some puts on the stock market as an added measure of insurance.
(Puts are options that increase in value when the market goes down, softening
the impact of any decline on the portfolio.) This small portion of the Fund's
Portfolio, as of December 31, 1999, becomes meaningful in the event of a sharp
or large decline in the market. Please refer to the Fund's holdings on page
nineteen for additional information on these options as of December 31, 1999.


Market Overview and Outlook
The 1999 stock market will go down in history as one of the most unusual markets
of all time. After recovering from the effects of the 1998 Asian

economic crises, the stock market soared to new heights and increased
volatility. During the beginning of the year, the market was very narrow with
only a small group of blue-chip stocks appreciating. In mid April, we
experienced a violent rotation into undervalued broad market stocks. By the end
of the year, while the market broadening continued to help some stocks, most of
the market's focus had shifted to the NASDAQ-listed technology companies. During
1999, market indices such as the S&P 500, and the Russell 3000 Index**** were up
over 20%; the NASDAQ composite Index+ ("NASDAQ") increased by 85.59% led by both
blue chip and speculative technology issues.

The most fundamental change in the market that we observed in 1999 was that all
of the historical rules of traditional security analysis seemed to be discarded.
Particularly in the Internet sector, the market rewarded concepts over profits.
In many cases it became disrespectful to report earnings -- the market instead
focused on issues such as number of potential customers instead of profitable
sales to actual customers. While the market seems to think that profitability
and cash flow are no longer important, the strategy of "buying sales" (i.e.
losing money on sales in order to establish a market share position) is as old
as commerce itself. The only difference this time is that the stock market is
ignoring the fact that in the end companies need to generate cash flow and
profits in order to survive and thrive.

How does one invest in this environment? The biggest adjustment to our process
in 1999 has been to increase our focus on the Internet. The development of the
Internet is one of those events that will change the way we live and work
forever. It is as fundamental a change as was the development of telephones or
the harnessing of electricity. These advances happen regularly throughout
history and we are living through one of those momentous times right now.

If you closely examine the Fund's portfolio, you will see that relatively little
of your money is invested in traditional Internet companies (i.e., the
"dot.coms"). We find the long-term risk and reward proposition in most of these
companies to be very unattractive. Most of these companies do not have
sustainable business models (translation: in our opinion they will always lose
money), while others have valuations that assume they will be the only survivors
in the eventual shakeout.

However, you will see a lot of your money invested in companies++ that benefit
from or build the Internet. In the Fund, we own companies such as...
 .    Seagate (a company that provides disk drives and software for storage as
     well as indirect exposure with partial ownership of companies such as
     Veritas)
 .    Federated Department Stores (one of the leading operators of full-line
     department stores and a leader in the "clicks and mortar" e-commerce
     strategy and owner of several valuable Internet businesses)
 .    GTE (a company merging with Bell Atlantic, the combined company will be the
     leading U.S. wireless company also offering telecom services such as local,
     long distance and high speed Internet access)

It is our strong belief that over time the leading established companies that
embrace today's new technologies should emerge as the dominant and most
profitable companies in the economy. Their stocks should recognize this over
time. On the other hand, we believe the stock market will eventually lose
patience with those traditional Internet companies that cannot transform
themselves into growth companies with enough profits to support their stock
price.

Going forward, we expect many companies to reap the benefits of their current
investments in technology. We also expect many technology companies to continue
to grow as they innovate. There will also be a maturing in the technology
sector, as it has become a bigger part of the market and economy than energy was
in the 1980s. During the next decade the technology sector will not go the way
of the energy sector, but the two industries in our view share a common factor.
The early 1980s expectations of oil prices soaring to $100 per barrel led to
extreme valuations for these companies and a gold rush effect of too much
capital being put into the sector. Eventually the laws of large numbers and
diminishing returns caught up with the energy sector. Cost of energy became too
large of an input into the economy and people figured out ways to utilize it
more efficiently at the same time that capacity was expanding rapidly.

With technology companies representing about 30% of the S&P 500, similar
long-term risks exist in the technology sector. This is partly offset by the
fact that technology investment improves productivity while higher energy prices
are merely increased costs. We keep these factors in mind even when we are only
forecasting out one year as stock prices discount the long-term prospects of
companies.

You can expect the Fund to consistently apply its investment strategy in the
future. We will invest in both users and manufacturers of technology when we
believe that their risk/reward ratios are favorable. At the same time the index
exposure in the Fund should provide some participation in the stock market
whether our particular investment style is in or out of favor.

Thank you for your investment in the Smith Barney Premium Total Return Fund. We
are looking forward to continuing to help you pursue your financial goals in the
new century.


Sincerely,

+    Hypothetical illustration of $10,000 invested in Class B shares on December
     31, 1989, assuming reinvestment of dividends and capital gains, if any, at
     net asset value through December 31, 1999, compared to the Standard &
     Poor's 500 Index. The index is composed of 500 widely held common stocks
     listed on the New York Stock Exchange, American Stock Exchange and
     over-the-counter market. The index is unmanaged and is not subject to the
     same management and trading expenses as a mutual fund. The performance of
     the Fund'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 values 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 from "AA" to "CCC" may be modified by the addition
of a plus (+) or a minus (-) sign to show relative standings within the major
rating categories.

AAA      -- Bonds rated "AAA" have the highest rating assigned by S&P to a debt
            obligation. Capacity to pay interest and repay principal is
            extremely strong.
AA       -- Bonds rated "AA" have a very strong capacity to pay interest and
            repay principal and differs from the highest rated 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
            debt 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 for
            bonds in higher rated categories.
BB, B,   -- Bonds rated "BB" and "B" are regarded, on balance, as predominantly
CCC         speculative with respect to  capacity to pay interest and repay
and CC      principal in accordance with the terms of the obligation. "BB"
            indicates a lower degree of speculation and "CC" the highest degree
            of speculation. While such bonds will likely have some quality and
            protective characteristics, these are outweighed by large
            uncertainties or major risk exposures to adverse conditions.

Moody's -- Numerical modifiers 1, 2, and 3 may be applied to each generic rating
from "Aa" to "Caa", 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 these bonds.
Aa       -- Bonds rated "Aa" are judged to be of the 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 that 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 that suggest a susceptibility to impairment
            some time in the future.
Baa      -- Bonds rated "Baa" are considered to be medium grade obligations;
            that is they are neither highly protected nor poorly secured.
            Interest payment 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. These
            bonds lack outstanding investment characteristics and may have
            speculative characteristics as well.
Ba       -- Bonds rated "Ba" are judged to have speculative elements; their
            future cannot be considered as well assured. Often the protection of
            interest and principal payments may be very moderate and thereby may
            not well safeguarded during both good and bad times over the future.
            Uncertainty of position characterizes bonds in this class.

B        -- Bonds rated "B" generally lack characteristics of desirable
            investments. Assurance of interest and principal payment or of
            maintenance of other terms of the contract over any long period of
            time may be small.
Caa      -- Bonds rated "Caa" are of poor standing. These issues may be in
            default, or present elements of danger may exist with respect to
            principal or interest.
NR       -- Indicates that the bond is not rated by Standard & Poor's or
            Moody's.

1. Significant Accounting Policies

The Smith Barney Premium Total Return Fund ("Fund"), a separate investment fund
of Smith Barney Income Funds ("Trust"), a Massachusetts business trust, is
registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company. The Trust consists of this
Fund and seven other separate investment funds: Smith Barney Exchange Reserve
Fund, Smith Barney Convertible Fund, Smith Barney High Income Fund, Smith Barney
Municipal High Income Fund, Smith Barney Diversified Strategic Income Fund,
Smith Barney Balanced Fund and Smith Barney Total Return Bond 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) investments are
valued at market value or, in the absence of market value with respect to any
portfolio securities, at fair value as determined by or under the direction of
the Board of Trustees. Portfolio securities that are traded primarily on a
domestic or foreign exchange are valued at the last sale price on that exchange
or, if there were no sales during the day, at the current quoted bid price.
Over-the-counter securities are valued on the basis of the bid price at the
close of business each day. Options are generally valued at the mean of the
quoted bid and asked prices. Investments in U.S. government securities (other
than short-term securities) are valued at the mean of the quoted bid and asked
price; (c) securities maturing within 60 days are valued at cost plus accreted
discount, or minus amortized premium, which approximates value; (d) interest
income, adjusted for amortization of premium and accretion of discount, is
recorded on the accrual basis; (e) dividend income is recorded on the
ex-dividend date; foreign dividend income is recorded on the ex-dividend date or
as soon as practical after the Fund determines the existence of a dividend
declaration after exercising reasonable due diligence; (f) dividends and
distributions to shareholders are recorded on the ex-dividend date; (g) gains or
losses on the sale of securities are calculated by using the specific
identification method; (h) the accounting records are maintained in U.S.
dollars. All assets and liabilities denominated in foreign currencies are
translated into U.S. dollars based on the rate of exchange of such currencies
against U.S. dollars on the date of valuation. Purchases and sales of
securities, and income and expenses are translated at the rate of exchange
quoted on the respective date that such transactions are recorded. Differences
between income and expense amounts recorded and collected or paid are adjusted
when reported by the custodian bank; (i) direct expenses are charged to each
class; management fees and general fund expenses are allocated on the basis of
relative net assets of each class; (j) 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 Fund's capital accounts to reflect permanent
book/tax differences and income and gains available for distributions under
income tax regulations. Accordingly, a portion of accumulated net realized gains
amounting to $153,385,958 was reclassified to paid-in capital. Net investment
income, net realized gains 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.

In addition, the Fund may from time to time enter into options and/or futures
contracts in order to hedge market risk.


2. Investment Advisory Agreement, Administration Agreement and Other
   Transactions

SSB Citi Fund Management LLC ("SSBC"), formerly known as SSBC Fund Management
Inc., 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 Trust. The Fund pays SSBC an advisory fee calculated at an annual
rate of 0.55% of the average daily net assets. This fee is calculated daily and
paid monthly.

SSBC has entered into a sub-advisory agreement with Salomon Brothers Asset
Management ("SaBAM"), an affiliate of SSBC. Pursuant to the sub-advisory
agreement, SaBAM is responsible for the day-to-day portfolio operations and
investment decisions for the Fund. Effective June 14, 1999, SSBC pays SaBAM a
monthly fee calculated at an annual rate of 0.15% of the average daily net
assets of the Fund. This fee is paid monthly. Prior to June 14, 1999, Boston
Partners Asset Management, L.P. was the Fund's sub-advisor and was paid a
monthly fee calculated at an annual rate of 0.15% of the Fund's average daily
net assets.

SSBC acts as the Fund's administrator for which the Fund 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.

Effective October 1999, Smith Barney Private Trust Company ("Private Trust"),
another subsidiary of Citigroup, became the Fund's transfer agent and PFPC
Global Fund Services ("PFPC") became the sub-transfer agent. Private Trust
receives account fees and asset-based fees that vary according to the size and
type of account. PFPC is responsible for shareholder recordkeeping and financial
processing for all shareholder accounts and is paid by Private Trust. During the
period October 1, 1999 through December 31, 1999, the Fund paid transfer agent
fees of $531,292 to Private Trust.

CFBDS, Inc. ("CFBDS") acts as the Fund's distributor. Salomon Smith Barney Inc.
("SSB"), another subsidiary of SSBH, as well as certain other broker-dealers,
continues to sell Fund shares to the public as a member of the selling group.

SSB acts as the primary broker for its portfolio agency transactions. For the
year ended December 31, 1999, SSB received total brokerage commissions of
$8,400.

There is a contingent deferred sales charge ("CDSC") of 5.00% on Class B shares,
which applies if redemption occurs within one year from purchase and declines
thereafter by 1.00% per year until no CDSC is incurred. Class L and O 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.

For the year ended December 31, 1999, CFBDS and SSB received sales charges of
$272,000 and $88,000 on sales of the Fund's Class A and Class L shares,
respectively. In addition, CDSCs paid to SSB were approximately:

                   Class A      Class B         Class L        Class O
================================================================================

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

All officers and one Trustee of the Trust are employees of SSB.


3. Investments

During the year ended December 31, 1999, the aggregate cost of purchases and
proceeds from sales of investments (including maturities, but excluding
short-term securities) were as follows:

================================================================================
Purchases                                                        $2,842,809,006
- --------------------------------------------------------------------------------
Sales                                                             4,718,050,327
================================================================================

At December 31, 1999, the aggregate gross unrealized appreciation and
depreciation of investments for Federal income tax purposes were substantially
as follows:

================================================================================
Gross unrealized appreciation                                      $375,774,413
Gross unrealized depreciation                                       (80,061,912)
- --------------------------------------------------------------------------------
Net unrealized appreciation                                        $295,712,501
================================================================================


4. Futures Contracts

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

The Fund enters into such contracts to hedge a portion of its portfolio. The
Fund bears the market risk that arises from changes in the value of the
financial instruments and securities indices (futures contracts) and the credit
risk should a counterparty fail to perform under such contracts.

At December 31, 1999, the Fund had the following open futures contracts:

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


5. Option Contracts

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

At December 31, 1999, the Fund had four purchased call options with a total cost
of $115,453,000 and sixteen purchased put options with a total cost of
$21,765,250.

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

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

The following written covered call option transactions occurred during the year
ended December 31, 1999:

6. Repurchase Agreements

The Fund 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 Fund requires continual maintenance
of the market value of the collateral in amounts at least equal to the
repurchase price.


7. Lending of Portfolio Securities

The Fund has an agreement with its custodian whereby the custodian may lend
securities owned by the Fund to brokers, dealers and other financial
organizations, and receives a lenders fee. Fees earned by the Fund on securities
lending are recorded in interest income. Loans of securities by the Fund 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.

Independent Auditors' Report
- --------------------------------------------------------------------------------
The Shareholders and Board of Trustees of
Smith Barney Income Funds:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Smith Barney Premium Total Return Fund of Smith
Barney Income Funds as of December 31, 1999, 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 the financial
highlights for each of the years in the three-year period then ended, the period
from August 1, 1996 to December 31, 1996 and for each of the years in the
two-year period ended July 31, 1996. 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 generally accepted auditing
standards. 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, 1999, by correspondence with the custodian. As to securities
purchased or sold but not yet received or delivered, we performed other
appropriate auditing procedures. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Smith
Barney Premium Total Return Fund of Smith Barney Income Funds as of December 31,
1999, 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 the
financial highlights for each of the periods referred to above, in conformity
with generally accepted accounting principles.

                                                                    /s/ KPMG LLP
