[LOGO]  Income and Broad Market Participation with Some Downside Protection

        Manager Ross S. Margolies and his team carefully seek to uncover
        tomorrow's growth and income opportunities.

[LOGO]  Diversification Matters

        Because the best performing asset class can change from year to
        year, investing across asset classes makes sense. Your investment in the
        Fund offers you a convenient way to participate in different asset
        classes. This combination may potentially help reduce overall risk to
        your portfolio. Keep in mind, diversification does not assure against
        market loss.

[LOGO]  An Asset Allocation Model

        Ross S. Margolies uses an asset allocation model which includes a
        combination of equity securities, fixed income securities with a
        participation in index futures, options and cash. * The strategic
        combination of these three elements looks to provide current income
        while maintaining the potential to provide most of the stock market's
        long-term appreciation, yet more downside protection than the market as
        a whole. Please note that the Fund's asset allocation is subject to
        change.

[LOGO]  A Commitment to Managing Your Serious Money

        SSB Citi Fund Management LLC ("SSB Citi"), the investment management
        division of Citigroup, is comprised of Smith Barney Asset
        Management, Salomon Brothers Asset Management and Citibank Global Asset
        Management, organizations with powerful investment capabilities.

        SSB Citi, as a member of one of the largest financial services providers
        in the world, offers you the benefits of our unparalleled global
        capabilities.

        At SSB Citi, you gain access to portfolio management delivered
        professionally. We are proud to offer you, the serious investor, a
        variety of managed solutions.

        * Please note that the Fund's asset allocation is subject to change.
          Futures (forward contracts traded on an established exchange) and
          options (contracts that represent the right to buy and sell an
          underlying asset by a specified time for a specified price) are also
          known as derivative contracts. A derivative is commonly defined as a
          financial instrument whose value is "derived" from, or based on, an
          underlying security, asset or index. Derivatives are subject to the
          same fundamental relationship between risk and potential return as are
          all investments. The higher the risk of a derivative, the greater its
          potential return. The lower the risk of the derivative, the lower its
          potential return. The Premium Total Return Fund may, but not need to,
          use derivative contracts, such as futures and options on securities,
          securities indices, options on futures, and swaps in order to hedge
          against the impact of adverse changes in the market value of portfolio
          securities because of changes in stock market prices or interest
          rates, as a substitute for buying and selling securities, and to
          increase the Fund's total return. Please note that even a small
          investment in derivative contracts can disproportionately increase
          losses and reduce opportunities for gains when stock prices and
          interest rates are changing. Moreover, the Fund may not fully benefit
          from or may lose money on derivatives if changes in their value do not
          correspond accurately to changes in the value of the Fund's holdings.
          The other parties to certain derivative contracts present the same
          types of default risk as issuers of fixed income securities. The use
          of derivatives can also make the Fund less liquid and harder to value,
          especially in declining markets. Principal value and investment
          returns will fluctuate and investors' shares, when redeemed, may be
          worth more or less than their original cost.

The Smith Barney Premium Total Return Fund was designed to provide the potential
for upside stock market participation, a competitive stream of income and some
downside protection. Increasing levels of market volatility have recently become
a part of the financial landscape, that in our view, clearly demonstrate the
necessity of professional money management. As professional money managers,
portfolio manager Ross S. Margolies and his team search for promising investment
opportunities.

<PAGE>

Dear Shareholder,

We are pleased to present the semi-annual report for the Smith Barney Premium
Total Return Fund ("Fund") for the period ended June 30, 2000. 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. We hope you find this
report to be informative and useful. Please note that the Fund's holdings are
subject to change and any discussion of holdings is as of June 30, 2000. Please
refer to pages 12 through 22 for a complete list and percentage breakdown of the
Fund's holdings.

Performance Update

For the six months ended June 30, 2000, the Fund's Class A shares, without sales
charges, returned 6.49%. The Fund's Class A shares, with sales charges, returned
1.18% for the same time period. During this same period, the U.S. stock market,
as measured by the Standard and Poor's 500 Index ("S&P 500")/1/ returned a
negative 0.43%.

We are pleased to report that the Premium Total Return Fund's relative
performance has improved over the past year./2/ We believe that our investment
strategy, which is described in greater detail later 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.)

               -------------------------------------------------
                    OUR INVESTMENT STRATEGY IS DESIGNED TO
                 PROVIDE THE POTENTIAL FOR UPSIDE STOCK MARKET
                    PARTICIPATION, A COMPETITIVE STREAM OF
                     INCOME AND SOME DOWNSIDE PROTECTION.
               -------------------------------------------------

Additional Fund performance information can be found on pages eight through ten.

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 generally assumes less risk than the overall
stock market, we believe 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.)

   common stocks. Please note that an investor cannot invest directly in an
   index.

2  Ross S. Margolies, a Managing Director and Co-Chief Investment Officer of
   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 Salomon Brothers
   Asset Management Inc ("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.

<PAGE>

Over shorter periods of time such as one year, we expect that the Fund should
post a total return (including dividends) of more than 75% of the S&P 500 during
rising markets and participate in less than 75% of the stock market's decline
during down years. We feel that these three Fund attributes -- the potential for
upside participation, competitive monthly income and potential protection -- are
appropriate based on the risk and reward needs of our shareholders.

Our core investment style is centered on a bottom-up/3/ stock picking strategy.
We focus on thoroughly understanding a company's business, its strategy,
competitive position and industry. We also seek to determine whether a
particular management is credible and the right team is in place to lead the
company under consideration. Our financial analysis focuses on a company's
resources to meet its goals and the consistency of the numbers to determine
their quality. (For instance, 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 and growing parts of the economy such
as technology, telecommunications, healthcare, financials and consumer.

                 -------------------------------------------
                     AN IMPORTANT PART OF OUR INVESTMENT
                           STRATEGY IS CONSISTENCY.
                 -------------------------------------------

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 some 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 index 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
mar-ket, in both directions, even if our equity investment approach is
temporarily out of favor. 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 holding 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.) As of June
30, 2000, this small portion of the Fund's portfolio, becomes meaningful in the
event of a sharp or large decline in the market.

Another important aspect of our investment strategy is consistency. The Fund's
shareholders that read these management discussions will note a consistency of
investment strategy and style over time. It is our belief that even an average
investment strategy (let alone a superior one) applied consistently over time
will outperform the appropriate market index over the long term. This is because
the strategy may be positioned to take advantage of the short-term overreactions
that the market has always had.

______________
3  A bottom-up approach to investing is to search for outstanding performance of
   individual stocks before considering the impact of economic trends.

Market Overview and Outlook

Even though it made no headway, the stock market offered something for everyone
during the first half of 2000. Initially the speculative momentum market of 1999
continued the market rally, peaking during the second week of March. The Fed's
continued increases in interest rates then continued, leading to a dramatic
sell-off, particularly in the volatile NASDAQ/4/ market, through May. At the
same time, many oversold "Old Economy" stocks rallied as money rotated from the
Internet and Biotechology stocks into areas such as consumer staples. By the end
of the half, most of the market losses were recovered so that most broad indices
were down modestly for the half of the year.

One way to describe what happened is that "investment gravity" finally took hold
of stocks that previously seemed to continually go up. The catalyst was the
seemingly unrelated comments by U.S. President Bill Clinton and British Prime
Minister Tony Blair that genomics companies would not reap all of the benefits
of the public research money devoted to their field of science. The sell-off in
Biotechology stocks spread like a contagion to all high-priced growth stocks.
For a relatively brief time, earnings counted and stories were discounted. Then
some Internet stocks, by the end of June, the market was once again awarding
future potential a premium to proven ability.

Our view is that the Fund's investment strategy worked well throughout the
period. When the market was rising, our broad, diversified stock exposure
allowed us to participate. When the market declined, the portfolio's structure
helped to dampen the effect. Positive stock selection, particularly in companies
that we still own such as Safeway (a food and drug chain), 3Com (a network
access and interface equipment company), Nabisco Group Holdings, (a food
products company), Seagate Technology, (a supplier of data storage products) and
Devon Energy, (a leading oil and gas producer), led to the Fund's outperforming
the market. (Of course, past performance is not indicative of future results.)

           ----------------------------------------------------------
              THE WIRELESS INTERNET, WHICH PROVIDES WEB ACCESS TO
               PALM HAND-HELD DEVICES, IS BEING PROMOTED AS THE
                MOST PROMISING TECHNOLOGICAL DEVELOPMENT SINCE
               THE INTERNET. INDUSTRY FORECASTS SAY THAT IN FIVE
               YEARS, AS MANY AS 500 MILLION PEOPLE WORLDWIDE --
                ONE OF EVERY DOZEN -- WILL HAVE PHONES OR OTHER
                DEVICES CAPABLE OF WIRELESS INTERNET ACCESS./5/
           ----------------------------------------------------------

Going forward we expect to hold many of these stocks but we will have to find
replacement ideas for some like Nabisco and Seagate which will be taken over
later this year. The convertible bonds we owned also were significant positive
Fund contributors during the reporting period -- this modest allocation to the
Fund's portfolio continues to be very important as it allows us to get exposure
to high-growth areas like Technology and Biotechnology while limiting the higher
risk of owning the stocks of the same companies.

We continue to see the growth of the Internet as one of the driving forces of
the economy going forward. 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, a view we see
the broad market starting to embrace. 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 any eventual shakeout in the Internet.

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:

  .  3Com, a company that split into two pieces on July 28, 2000 -- Palm, Inc.
     maker of the Palm Pilot, the leading Personal Digital Assistant ("PDA")
     which will soon offer wireless Internet access and the remaining 3Com
     networking business helping individual access the Internet;

  .  Federated Department Stores, a leader in the "clicks and mortar" e-commerce
     strategy and owner of several valuable Internet businesses; and

  .  Verizon Communications, formed from the merger of Bell Atlantic and
     GTE; Verizon Communications is the leading U.S. wireless company also
     offering telecom services such as local, long distance and high speed
     Internet access

It is our 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. And while no guarantees can be given, their stocks
should recognize this over time. On the other hand, we believe the stock market
will continue to lose patience with those traditional Internet companies that
cannot transform themselves into growth companies with enough profits to support
their stock price.

We will invest in both users and manufacturers of technology when we believe
that their risk and reward ratios are favorable. At the same time, we believe
that the S&P 500 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 June 30,
     1990, assuming reinvestment of dividends and capital gains, if any, at net
     asset value through June 30, 2000, 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,  -- Bonds rated "BB" and "B" are regarded, on balance, as predominantly
B,      speculative with respect to capacity to pay

CCC     interest and repay principal in accordance with the terms of the
        obligation. "BB" indicates a lower degree of
and CC  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.

D    -- Bonds rated "D" are in default, and payment of interest and/or repayment
        of principal is in arrears.

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 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 the 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.

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.

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 Fund's sub-transfer
agent. CFTC receives account fees and asset-based fees that vary according to
the size and type of account. PFPCis 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 Fund paid transfer agent fees of
$863,461 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 received brokerage commissions of $37,668.

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
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 six months ended June 30,2000, CFBDS and SSB received sales charges of
$68,000 and $30,000 on sales of the Fund's Class A and Class L
shares, respectively. In addition, CDSCs paid to SSB were approximately:

--------------------------------------------------
Net unrealized appreciation          $ 241,203,112
==================================================

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 counter-party fail to perform under such contracts.

At June 30, 2000, 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 June 30, 2000, the Fund had three purchased call options with a total cost of
$53,102,750 and ten purchased put options with a total cost of $14,600,675.

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 six
months ended June 30, 2000:

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.
