SELIGMAN -- TIMES CHANGE...VALUES ENDURE

J. & W. SELIGMAN & CO. INCORPORATED IS A FIRM WITH A LONG TRADITION OF
INVESTMENT EXPERTISE, OFFERING A BROAD ARRAY OF INVESTMENT CHOICES TO HELP
TODAY'S INVESTORS SEEK THEIR LONG-TERM FINANCIAL GOALS.


TIMES CHANGE...
Established in 1864, Seligman has a history of providing financial services
marked not by fanfare, but rather by a quiet and firm adherence to financial
prudence. While the world has changed dramatically in the 136 years since
Seligman first opened its doors, the firm has continued to offer its clients
high-quality investment solutions through changing times.

In the late 19th century, as the country grew, Seligman helped finance the
westward expansion of the railroads, the construction of the Panama Canal, and
the launching of urban transit systems. In the first part of the 20th century,
as America became an industrial power, the firm helped fund the growing capital
needs of the nascent automobile and steel industries.

With the formation of Tri-Continental Corporation in 1929 -- today, the nation's
largest diversified publicly-traded closed-end investment company -- Seligman
began shifting its emphasis from investment banking to investment management.
Despite the stock market crash and ensuing depression, Seligman was convinced of
the importance that investment companies could have in building wealth for
individual investors and began managing its first mutual fund in 1930.

In the decades that followed, Seligman has continued to offer forward-looking
investment solutions, including equity funds that specialize in small companies,
technology, or international securities, and bond funds that focus on high-yield
issuers, US government bonds, or municipal securities.

 ...VALUES ENDURE
Seligman is proud of its distinctive past and of the traditional values that
continue to shape the firm's business decisions and investment judgment. While
much has changed over the years, the firm's commitment to providing prudent
investment management that seeks to build wealth for clients over time is an
enduring value that will guide Seligman in the new millennium.

TO THE SHAREHOLDERS

The first half of 2000 was a challenging time for the stock market, while the
bond market stabilized and outperformed equities. In this environment, Seligman
Income Fund, which invests in both the equity and fixed-income markets,
delivered a total return of 0.75% based on the net asset value of Class A
shares, while the Lipper Income Funds Average returned 1.88% and the Lehman
Brothers Aggregate Bond Index returned 3.99%. The stock market, as measured by
the Standard & Poor's 500 Composite Stock Price Index (S&P 500) declined -0.42%.
These returns were not surprising, given the economic environment.

As early as June 1999, in an effort to slow the economy, the Federal Reserve
Board began raising interest rates. Over the course of this one-year period, the
federal funds rate was increased by 175 basis points, from 4.75%, before the
June 1999 Fed meeting, to 6.50%, following the most recent increase of 50 basis
points in May 2000. Despite these persistent tightening actions, the Fed's
efforts seemed to have little effect on the strong US economy. Investors soon
became concerned that the Fed would be unable to achieve its objective of an
economic "soft landing." Ongoing economic strength could also prompt the Fed to
continue raising interest rates, possibly significantly, which could adversely
affect corporate profits and stock prices.

Although short-term rates moved significantly higher during the period,
long-term rates actually declined, for a sustained bond market rally. At the
beginning of the period, the 30-year US Treasury bond was yielding 6.6%; by the
end of the period, it was yielding 5.9% -- a decrease of 70 basis points.
Seligman Income Fund benefited from its balanced exposure to the bond market
during this time.

Investor fear finally induced a significant correction in the Nasdaq Composite
Index (a technology-heavy index) in March. From March 10 through May 23, 2000,
this index lost 37% of its market value. During this correction, investors
abandoned some of the high-risk, and often speculative, technology stocks that
had been in demand for most of 1999.

Looking ahead, we believe that the economy will continue to moderate, and that
Seligman Income Fund, which is balanced among stocks and bonds, should perform
well in such an environment. Investors should work with their financial advisors
to ensure that their portfolios are appropriately balanced based upon their time
frames, their risk tolerances, and their unique financial situations.

While we feel that the economic slowdown and the corresponding moderation of the
stock market are healthy long-term trends, the investment environment may in
fact become more challenging. The rest of 2000 may present an environment that
is more complex, making professional management and diversification, such as is
offered through mutual funds, crucial. Mutual funds provide investors with an
opportunity to obtain the services of money managers who have years of
investment experience and the support of research teams to find the most
promising opportunities. Mutual funds can also provide diversification, which is
important for long-term investment success.

Thank you for your continued support of Seligman Income Fund. A discussion with
your Portfolio Managers, as well as the Fund's investment results, portfolio of
investments, and financial statements, follows this letter. We look forward to
continuing to serve your investment needs.

By order of the Board of Directors,

INTERVIEW WITH YOUR PORTFOLIO MANAGERS,
CHARLES C. SMITH, JR. AND RODNEY COLLINS

Q:  HOW DID SELIGMAN INCOME FUND PERFORM DURING THE FIRST SIX MONTHS OF 2000?
A:  During the first six months of 2000, Seligman Income Fund posted a total
    return of 0.75% based on the net asset value of Class A shares. At the same
    time, the Lipper Income Funds Average returned 1.88%, the Lehman Brothers
    Aggregate Bond Index returned 3.99%, and the S&P 500 returned -0.42%.

Q:  WHAT ECONOMIC AND MARKET FACTORS AFFECTED THE FUND'S PERFORMANCE DURING THE
    FIRST HALF OF THE FISCAL YEAR?
A:  The Federal Reserve Board has been raising interest rates, steadily and
    somewhat aggressively, for one full year now in an attempt to place a drag
    on the economy. At first, these actions seemed to have little or no effect
    -- consumer confidence remained high, which fueled spending; unemployment
    remained historically low, which nearly created a labor shortage; and price
    increases in some areas of the economy seemed to be accelerating.

    Toward the end of the first quarter of 2000, investors began to worry that
    the Fed's actions thus far had been insufficient, forcing it to continue to
    raise rates, which could adversely affect stocks. This growing uncertainty
    finally toppled the most richly valued stocks -- mostly technology stocks --
    by the middle of March. The Nasdaq Composite Index (a technology-heavy
    index) peaked at 5049 on March 10 and reached a low of 3165 on May 23 -- a
    37% decline from peak to trough. During this two-month period of steep
    losses in the technology sector, investors began to focus on companies that
    could deliver solid earnings, rather than just on those whose prices had
    been driven by momentum.

    In June, evidence began to appear that the economy was in fact slowing, and
    at the Fed's June meeting interest rates were left unchanged -- a
    confirmation that the Fed was becoming convinced that its previous actions
    were having the desired effect. This lifted some of the uncertainty from the
    market, and technology stocks staged a recovery, while value-style stocks
    lagged for the month.

    While short-term rates rose during this time, long-term yields actually
    fell. The long end of the bond market was anticipating an economic slowdown
    and an end to the Fed's tightening monetary actions. So despite the Fed's
    continued rate hikes, the bond market rallied and fixed-income securities
    outperformed common stocks for the first six months of the year.

--------------------------------------------------------------------------------
A TEAM APPROACH

Seligman Income Fund is managed by the Seligman Growth and Income Team, headed
by Charles C. Smith, Jr. Mr. Smith and Rodney Collins, the Fund's Co-Portfolio
Manager, are assisted in the management of the Fund by seasoned research
professionals who are responsible for identifying the most attractive corporate
and government securities and dividend-paying common stocks, consistent with the
Fund's objective.

INTERVIEW WITH YOUR PORTFOLIO MANAGERS,
CHARLES C. SMITH, JR. AND RODNEY COLLINS

Q:  WHAT WAS YOUR INVESTMENT STRATEGY?

A:  We continued to focus on pursuing greater total return potential for the
    portfolio. At period-end, the portfolio was 57% invested in common stocks
    and 42% invested in fixed-income securities. This represents a significantly
    greater exposure to common stocks than the Fund has had historically. We
    believe that, over the long term, this more balanced approach will provide
    the Fund with increased opportunities for capital appreciation.

    During the first six months of this year, the bond portion of the portfolio
    delivered the strongest results, and the Fund benefited from its balanced
    structure. The bond portfolio was generally 55% invested in corporate
    fixed-income securities, 40% in US government securities, and 5% in cash.
    The portfolio continues to consist of high-quality issues, with fewer than
    1% of the bonds in the portfolio rated below investment grade.

    In the equity portion of the portfolio, we continued to underweight
    technology stocks because we believed that this sector was excessively
    valued. However, in March, when this sector experienced a correction, we
    increased the Fund's exposure to technology, and we will continue to watch
    for opportunities if the sector continues to experience price weakness.
    However, we will remain mindful of valuations, and will not pursue these
    companies if we think their prices are unreasonable. We believe that the
    weakness in technology will continue through the end of the summer and into
    the fall, and we'll look for opportunities to take advantage of any such
    weakness to buy high-quality technology companies for the portfolio.

Q:  WHAT SECTORS CONTRIBUTED POSITIVELY TO PORTFOLIO PERFORMANCE?
A:  Seligman Income Fund's overweighting in energy and utilities was clearly a
    benefit during the first half of the year as the increase in oil prices and
    increased demand for natural gas pushed stocks for these companies higher.
    We think energy stocks will continue to do well as the global economy
    continues to recover.

    The Fund remained overweighted in financial stocks. Although these stocks
    generally do not perform well in a rising-rate environment -- and, in fact,
    the sector as a whole was flat for the period -- the financial stocks in the
    portfolio delivered generally strong performances, and they made a positive
    contribution to the Fund's returns.

Q:  WHAT SECTORS DETRACTED FROM PORTFOLIO PERFORMANCE?
A:  The worst-performing market sectors during the first half of the year were
    basic materials, consumer stocks, and telecommunications. Fortunately, the
    Fund was underweighted in basic materials and consumer stocks. We were
    overweighted in telecommunications, which hurt the Fund's performance
    relative to its benchmarks, but we plan to remain overweighted, because we
    believe that these stocks represent good value for the long term.

Q:  WHAT IS YOUR OUTLOOK?

A:  We expect the economy and the stock market will continue to moderate, as we
    began to see during the end of the first half of the year. In such an
    environment, we feel that investors will once again focus on corporate
    earnings and stock-price valuations. We have said for some time that the
    exuberance in the market would necessarily have to abate, and that the
    market would, at some point, once again focus on fundamentals. We believe
    this is beginning to happen and that it should favor the Fund's investment
    approach which focuses on identifying well-managed companies that trade at
    what we believe are attractive valuations relative to their earnings and
    cash flow. However, market cycles do not end overnight. We expect relatively
    high market volatility through the end of the year, although perhaps not to
    the extent that we saw in 1999. We also feel that the market will continue
    to broaden, which should benefit a well-diversified portfolio, such as that
    of Seligman Income Fund.

These charts reflect the growth of a $10,000 investment for a 10-year period for
Class A shares and since inception for Class B, Class C, and Class D shares,
assuming that all distributions within the periods are invested in additional
shares. Since the measured periods vary, the charts are plotted using different
scales and are not comparable.

----------
 * Net of the 4.75% or 1% maximum initial sales charge for Class A or Class C
   shares, respectively.
** Excludes the effects of the 2% or 1% CDSC for Class B or Class C shares,
   respectively.

----------
 * Non-income producing security.

 + Investments in mortgage-backed and asset-backed securities are subject to
   principal paydowns. As a result of prepayments from refinancing or
   satisfaction of the underlying instruments, the average life may be less than
   the original maturity. This in turn may impact the ultimate yield realized
   from these instruments.

++ Deferred-interest debentures pay no interest for a stipulated number of
   years, after which they pay the indicated coupon rate.

NOTES TO FINANCIAL STATEMENTS


1. MULTIPLE CLASSES OF SHARES -- Seligman Income Fund, Inc. (the "Fund") offers
four classes of shares. Class A shares are sold with an initial sales charge of
up to 4.75% and a continuing service fee of up to 0.25% on an annual basis.
Class A shares purchased in an amount of $1,000,000 or more are sold without an
initial sales charge but are subject to a contingent deferred sales charge
("CDSC") of 1% on redemptions within 18 months of purchase. Class B shares are
sold without an initial sales charge but are subject to a distribution fee of
0.75% and a service fee of up to 0.25% on an annual basis, and a CDSC, if
applicable, of 5% on redemptions in the first year of purchase, declining to 1%
in the sixth year and 0% thereafter. Class B shares will automatically convert
to Class A shares on the last day of the month that precedes the eighth
anniversary of their date of purchase. The Fund began offering Class C shares on
May 27, 1999. Class C shares are sold with an initial sales charge of up to 1%
and are subject to a distribution fee of up to 0.75% and a service fee of up to
0.25% on an annual basis, and a CDSC, if applicable, of 1% imposed on
redemptions made within 18 months of purchase. Class D shares are sold without
an initial sales charge but are subject to a distribution fee of up to 0.75% and
a service fee of up to 0.25% on an annual basis, and a CDSC, if applicable, of
1% imposed on redemptions made within one year of purchase. The four classes of
shares represent interests in the same portfolio of investments, have the same
rights and are generally identical in all respects except that each class bears
its separate distribution and certain other class-specific expenses, and has
exclusive voting rights with respect to any matter on which a separate vote of
any class is required.

2. SIGNIFICANT ACCOUNTING POLICIES -- The financial statements have been
prepared in conformity with accounting principles generally accepted in the
United States of America, which require management to make certain estimates and
assumptions at the date of the financial statements. The following summarizes
the significant accounting policies of the Fund:

a.  SECURITY VALUATION -- Investments in US Government and Government agency
    securities, bonds, and stocks are valued at current market values or, in
    their absence, at fair values determined in accordance with procedures
    approved by the Board of Directors. Securities traded on an exchange are
    valued at last sales prices or, in their absence and in the case of
    over-the-counter securities, at the mean of bid and asked prices. Short-term
    holdings maturing in 60 days or less are valued at amortized cost.

b.  FOREIGN CURRENCY TRANSACTIONS -- The books and records of the Fund are
    maintained in US dollars. The market value of investment securities, other
    assets and liabilities denominated in foreign currencies are translated into
    US dollars at the daily rate of exchange as reported by a pricing service.
    Purchases and sales of investment securities, income, and expenses are
    translated into US dollars at the rate of exchange prevailing on the
    respective dates of such transactions.

      The Fund separates that portion of the results of operations resulting
    from changes in the foreign exchange rates from the fluctuations arising
    from changes in the market prices of securities held in the portfolio.
    Similarly, the Fund separates the effect of changes in foreign exchange
    rates from the fluctuations arising from changes in the market prices of
    portfolio securities sold during the period.

c.  FEDERAL TAXES -- There is no provision for federal income tax. The Fund has
    elected to be taxed as a regulated investment company and intends to
    distribute substantially all taxable net income and net gain realized.

d.  SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME -- Investment
    transactions are recorded on trade dates. Identified cost of investments
    sold is used for both financial statement and federal income tax purposes.
    Dividends receivable and payable are recorded on ex-dividend dates, except
    that certain dividends from foreign securities where the ex-dividend dates
    may have passed are recorded as soon as the Fund is informed of the
    dividend. Interest income is recorded on an accrual basis.

e.  MULTIPLE CLASS ALLOCATIONS -- All income, expenses (other than
    class-specific expenses), and realized and unrealized gains or losses are
    allocated daily to each class of shares based upon the relative value of
    shares of each class. Class-specific expenses, which include distribution
    and service fees and any other items that are specifically attributable to a
    particular class, are charged directly to such class. For the six months
    ended June 30, 2000, distribution and service fees were the only
    class-specific expenses.

f.  DISTRIBUTIONS TO SHAREHOLDERS -- The treatment for financial statement
    purposes of distributions made to shareholders during the year from net
    investment income or net realized gains may differ from their ultimate
    treatment for federal income tax purposes. These differences are caused
    primarily by differences in the timing of the recognition of certain
    components of income, expense, or realized capital gain for federal income
    tax purposes. Where such differences are permanent in nature, they are
    reclassified in the components of net assets based on their ultimate
    characterization for federal income tax purposes. Any such reclassification
    will have no effect on net assets, results of operations, or net asset
    values per share of the Fund.

NOTES TO FINANCIAL STATEMENTS

3. PURCHASES AND SALES OF SECURITIES -- Purchases and sales of portfolio
securities, excluding US Government obligations and short-term investments, for
the six months ended June 30, 2000, amounted to $67,468,510 and $94,368,283,
respectively; purchases and sales of USGovernment obligations were $7,332,292
and $5,796,651, respectively.

    At June 30, 2000, the cost of investments for federal income tax purposes
was substantially the same as the cost for financial reporting purposes, and the
tax basis gross unrealized appreciation and depreciation of portfolio securities
amounted to $21,150,901 and $12,174,931, respectively.

4. MANAGEMENT FEE, DISTRIBUTION SERVICES, AND OTHER TRANSACTIONS -- J. & W.
Seligman & Co. Incorporated (the "Manager") manages the affairs of the Fund and
provides the necessary personnel and facilities. Compensation of all officers of
the Fund, all directors of the Fund who are employees or consultants of the
Manager, and all personnel of the Fund and the Manager is paid by the Manager.
The Manager receives a fee, calculated daily and payable monthly, equal to 0.60%
per annum of the first $1 billion of the Fund's average daily net assets, 0.55%
per annum of the next $1 billion of the Fund's average daily net assets, and
0.50% per annum of the Fund's average daily net assets in excess of $2 billion.
The management fee reflected in the Statement of Operations represents 0.60% per
annum of the Fund's average daily net assets.

    Seligman Advisors, Inc. (the "Distributor"), agent for the distribution of
the Fund's shares and an affiliate of the Manager, received concessions of
$3,175 from sales of Class A shares. Commissions of $24,795 and $9,360 were paid
to dealers for sales of Class A and Class C shares, respectively.

    The Fund has an Administration, Shareholder Services and Distribution Plan
(the "Plan") with respect to distribution of its shares. Under the Plan, with
respect to Class A shares, service organizations can enter into agreements with
the Distributor and receive a continuing fee of up to 0.25% on an annual basis,
payable quarterly, of the average daily net assets of the Class A shares
attributable to the particular service organizations for providing personal
services and/or the maintenance of shareholder accounts. The Distributor charges
such fees to the Fund pursuant to the Plan. For the six months ended June 30,
2000, fees incurred under the Plan aggregated $223,821, or 0.25% per annum of
the average daily net assets of Class A shares.

    Under the Plan, with respect to Class B shares, Class C shares, and Class D
shares, service organizations can enter into agreements with the Distributor and
receive a continuing fee for providing personal services and/or the maintenance
of shareholder accounts of up to 0.25% on an annual basis of the average daily
net assets of the Class B, Class C, and Class D shares for which the
organizations are responsible; and, for Class C and Class D shares, fees for
providing other distribution assistance of up to 0.75% on an annual basis of
such average daily net assets. Such fees are paid monthly by the Fund to the
Distributor pursuant to the Plan.

    With respect to Class B shares, a distribution fee of 0.75% on an annual
basis of average daily net assets is payable monthly by the Fund to the
Distributor; however, the Distributor has sold its rights to this fee to a third
party (the "Purchaser"), which provides funding to the Distributor to enable it
to pay commissions to dealers at the time of the sale of the related Class B
shares.

    For the six months ended June 30, 2000, fees incurred under the Plan,
equivalent to 1% per annum of the average daily net assets of Class B, Class C,
and Class D shares, amounted to $97,971, $10,436, and $235,112, respectively.

    The Distributor is entitled to retain any CDSC imposed on certain
redemptions of Class A and Class C shares occurring within 18 months of purchase
and on redemptions of Class D shares occurring within one year of purchase. For
the six months ended June 30, 2000, such charges amounted to $3,235.

    The Distributor has sold its rights to collect any CDSC imposed on
redemptions of Class B shares to the Purchaser. In connection with the sale of
its rights to collect any CDSC and the distribution fees with respect to Class B
shares described above, the Distributor receives payments from the Purchaser
based on the value of Class Bshares sold. The aggregate of such payments
retained by the Distributor, for the six months ended June 30, 2000, amounted to
$1,040.

    Seligman Services, Inc., an affiliate of the Manager, is eligible to receive
commissions from certain sales of shares of the Fund, as well as distribution
and service fees pursuant to the Plan. For the six months ended June 30, 2000,
Seligman Services, Inc. received commissions of $2,864 from the sales of shares
of the Fund. Seligman Services, Inc. also received distribution and service fees
of $19,350, pursuant to the Plan.

    Seligman Data Corp., which is owned by the Fund and certain associated
investment companies, charged the Fund at cost $267,521 for shareholder account
services. The Fund's investment in Seligman Data Corp. is recorded at a cost of
$3,553.

    Certain officers and directors of the Fund are officers or directors of the
Manager, the Distributor, Seligman Services, Inc., and/or Seligman Data Corp.

    The Fund has a compensation arrangement under which directors who receive
fees may elect to defer receiving such



                                       15

NOTES TO FINANCIAL STATEMENTS

fees. Directors may elect to have their deferred fees accrue interest or earn a
return based on the performance of the Fund or other funds in the Seligman Group
of Investment Companies. The cost of such fees and earnings accrued thereon is
included in directors' fees and expenses, and the accumulated balance thereof at
June 30, 2000, of $90,537 is included in other liabilities. Deferred fees and
related accrued earnings are not deductible for federal income tax purposes
until such amounts are paid.

5. COMMITTED LINE OF CREDIT -- The Fund is a participant in a joint $825 million
committed line of credit that is shared by substantially all open-end funds in
the Seligman Group of Investment Companies. The Fund's borrowings are limited to
10% of its net assets. Borrowings pursuant to the credit facility are subject to
interest at a rate equal to the overnight federal funds rate plus 0.50%. The
Fund incurs a commitment fee of 0.10% per annum on its share of the unused
portion of the credit facility. The credit facility may be drawn upon only for
temporary purposes and is subject to certain other customary restrictions. The
credit facility commitment expires in June 2001, but is renewable annually with
the consent of the participating banks. For the six months ended June 30, 2000,
the Fund did not borrow from the credit facility.

6. CAPITAL LOSS CARRYFORWARD -- At December 31, 1999, the Fund had a net capital
loss carryforward for federal income tax purposes of $910,188, which is
available for offset against future taxable net capital gains, expiring in 2007.
Accordingly, no capital gains distributions are expected to be paid to
shareholders until net capital gains have been realized in excess of the
available capital loss carryforwards.

7. CAPITAL SHARE TRANSACTIONS -- The Fund has authorized 500,000,000 shares of
$1 par value Capital Stock. Transactions in shares of Capital Stock were as
follows:

FINANCIAL HIGHLIGHTS


    The tables below are intended to help you understand each Class's financial
performance for the past five and one-half years or from its inception if less
than five and one-half years. Certain information reflects financial results for
a single share of a Class that was held throughout the periods shown. Per share
amounts are calculated using average shares outstanding. "Total return" shows
the rate that you would have earned (or lost) on an investment in each Class,
assuming you reinvested all your dividends and capital gain distributions. Total
returns do not reflect any sales charges and are not annualized for periods of
less than one year.

REPORT OF INDEPENDENT AUDITORS


--------------------------------------------------------------------------------
THE BOARD OF DIRECTORS AND SHAREHOLDERS,
SELIGMAN INCOME FUND, INC.:

We have audited the accompanying statement of assets and liabilities of Seligman
Income Fund, Inc., including the portfolio of investments, as of June 30, 2000,
and the related statements of operations for the six months then ended, and of
changes in net assets for the six months then ended and for the year ended
December 31, 1999, and the financial highlights for each of the periods
presented. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements.

Our procedures included confirmation of securities owned as of June 30, 2000, by
correspondence with the Fund's custodian and brokers; where replies were not
received from brokers, we performed other 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
Seligman Income Fund, Inc. as of June 30, 2000, the results of its operations
for the six months then ended, and the changes in its net assets and the
financial highlights for all the respective stated periods in conformity with
accounting principles generally accepted in the United States of America.

GLOSSARY OF FINANCIAL TERMS


CAPITAL GAIN DISTRIBUTION -- A payment to mutual fund shareholders of profits
realized on the sale of securities in a fund's portfolio.

CAPITAL APPRECIATION/DEPRECIATION -- An increase or decrease in the market value
of a mutual fund's portfolio securities, which is reflected in the net asset
value of the fund's shares. Capital appreciation/depreciation of an individual
security is in relation to the original purchase price.

COMPOUNDING -- The change in the value of an investment as shareholders receive
earnings on their investment's earnings. For example, if $1,000 is invested at a
fixed rate of 7% a year, the initial investment is worth $1,070 after one year.
If the return is compounded, second year earnings will not be based on the
original $1,000, but on the $1,070, which includes the first year's earnings.

CONTINGENT DEFERRED SALES CHARGE (CDSC) -- Depending on the class of shares
owned, a fee charged by a mutual fund when shares are sold back to the fund. The
CDSC expires after a fixed time period.

DIVIDEND -- A payment by a mutual fund, usually derived from the fund's net
investment income (dividends and interest less expenses).

DIVIDEND YIELD -- A measurement of a fund's dividend as a percentage of the
maximum offering price or net asset value.

EXPENSE RATIO -- The cost of doing business for a mutual fund, expressed as a
percent of the fund's net assets.

INVESTMENT OBJECTIVE -- The shared investment goal of a fund and its
shareholders.

MANAGEMENT FEE -- The amount paid by a mutual fund to its investment advisor(s).

MULTIPLE CLASSES OF SHARES -- Although an individual mutual fund invests in only
one portfolio of securities, it may offer investors several purchase options
which are "classes" of shares. Multiple classes permit shareholders to choose
the fee structure that best meets their needs and goals. Generally, each class
will differ in terms of how and when sales charges and certain fees are
assessed.

NATIONAL ASSOCIATION OF SECURITIES DEALERS, INC. (NASD) -- A self-regulatory
body with authority over firms that distribute mutual funds.

NET ASSET VALUE (NAV) PER SHARE -- The market worth of one fund share, obtained
by adding a mutual fund's total assets (securities, cash, and any accrued
earnings), subtracting liabilities, and dividing the resulting net assets by the
number of shares outstanding.

OFFERING PRICE -- The price at which a mutual fund's share can be purchased. The
offering price per share is the current net asset value plus any sales charge.

PORTFOLIO TURNOVER -- A measure of the trading activity in a mutual fund's
investment portfolio that reflects how often securities are bought and sold.

PROSPECTUS -- The legal document describing a mutual fund to all prospective
shareholders. It contains information required by the Securities and Exchange
Commission (SEC), such as a fund's investment objective and policies, services,
investment restrictions, how shares are bought and sold, fund fees and other
charges, and the fund's financial highlights.

SEC YIELD -- SEC Yield refers to the net income earned by a fund during a recent
30-day period. This income is annualized and then divided by the maximum
offering price per share on the last day of the 30-day period. The SEC Yield
formula reflects semiannual compounding.

SECURITIES AND EXCHANGE COMMISSION -- The primary US federal agency that
regulates the registration and distribution of mutual fund shares.

STATEMENT OF ADDITIONAL INFORMATION -- A document that contains more detailed
information about an investment company and that supplements the prospectus. It
is available at no charge upon request.

TOTAL RETURN -- A measure of a fund's performance encompassing all elements of
return. Reflects the change in share price over a given period and assumes all
distributions are taken in additional fund shares. The AVERAGE ANNUAL TOTAL
RETURN represents the average annual compounded rate of return for the periods
presented.

YIELD ON SECURITIES -- For bonds, the current yield is the coupon rate of
interest, divided by the purchase price. For stocks, the yield is measured by
dividing dividends paid by the market price of the stock.
