Supplement, dated August 11, 2000, to the
Statement of Additional Information, dated May 1, 2000,
of Seligman High Income Fund Series (the "Fund")
on behalf of its
Seligman U.S. Government Securities Series
Seligman High-Yield Bond Series
(collectively, the "Series")
Effective August 11, 2000, the following disclosure replaces (a) the last
two full paragraphs in the discussion of "Calculation of Performance Data" on
pages 31 and 32 and (b) the seventh full paragraph under the section "General
Information -- Custodian" on page 33 of the Fund's Statement of Additional
Information:
Pages 31 and 32
From time to time, reference may be made in advertisements, sales literature or
other promotional material (collectively, "Promotional Material") to performance
information, including mutual fund rankings prepared by independent reporting
services which monitor the performance of mutual funds, including but not
limited to Lipper Analytical Services, Inc. and Morningstar, Inc. In calculating
the total return of the Series' Class A, Class B, Class C, and Class D shares,
the Lipper analysis assumes investment of all dividends and distributions paid,
but does not take into account applicable sales charges. Morningstar's rankings
are calculated using a fund's average annual returns for a certain period and a
risk factor that reflects a fund's performance relative to three-month Treasury
Bill monthly returns. Morningstar's ratings range from five stars (highest) to
one star (lowest) and represent Morningstar's assessment of the historical risk
level and total return of a fund for 3-, 5-, and 10-year periods and, on an
overall basis, based on weighted-average of those periods. Ratings are not
absolute and do not represent future performance results.
Each Series' Promotional Material may disclose (i) the top ten holdings included
in the Series' portfolio holdings, (ii) market sectors and statistical data
describing portfolio composition, (iii) discussions of general economic or
financial principals, (iv) discussions of general economic trends, (v)
descriptions of investment strategies for each Series (vi) descriptions or
comparisons of various savings and investment products, which may not include a
Series and (vii) comparisons of investment products (including a Series) with
relevant market or industry indices or appropriate benchmarks. Each Series may
also include calculations, such as hypothetical compounding examples, which
describe hypothetical investment results. Such performance examples will be
based on an express set of assumptions and are not indicative of the future
performance of the Series.
From time to time, each Series' Promotional Materials may portray the historical
returns of various asset classes. Such presentations will typically compare the
average annual rates of return of inflation, U.S. Treasury bills, bonds,
large-cap stocks, and small-cap stocks. There are important differences between
each of these investments that should be considered in viewing any such
comparison. The market value of stocks will fluctuate with market conditions,
and small-stock prices generally will fluctuate more than large-stock prices.
Stocks are generally more volatile than bonds. In return for this volatility,
stocks have generally performed better than bonds or cash over time. Bond prices
generally will fluctuate inversely with interest rates and other market
conditions, and the prices of bonds with longer maturities generally will
fluctuate more than those of shorter-maturity bonds. Interest rates for bonds
may be fixed at the time of issuance, and payment of principal and interest may
be guaranteed by the issuer and, in the case of U.S. Treasury obligations,
backed by the full faith and credit of the U.S. Treasury.
Each Series may also refer in Promotional Material to selections from editorials
or articles about the Series, including reprints of comments, listings and
columns in the financial and other press, the sources of which include BARRON'S,
BUSINESS WEEK, CDA/WIESENBERGER MUTUAL FUNDS INVESTMENT REPORT, CHRISTIAN
SCIENCE MONITOR, FINANCIAL PLANNING, FINANCIAL TIMES, FINANCIAL WORLD, FORBES,
FORTUNE, INDIVIDUAL INVESTOR, INVESTMENT ADVISOR, INVESTORS BUSINESS DAILY,
KIPLINGER'S, LOS ANGELES TIMES, MONEY MAGAZINE, MORNINGSTAR, INC., PENSION AND
INVESTMENTS, SMART MONEY, THE NEW YORK TIMES, THE WALL STREET JOURNAL, USA
TODAY, U.S. NEWS AND WORLD REPORT, WORTH MAGAZINE, WASHINGTON POST and YOUR
MONEY.
Each Series' Promotional Material may make reference to a Series' "Beta,"
"Standard Deviation," or "Alpha." Beta measures the volatility of a Series, as
compared to that of the overall market. Standard deviation measures how widely
the Series' performance has varied from its average performance, and is an
indicator of the Series' potential for volatility. Alpha measures the difference
between the returns of a Series and the returns of the market, adjusted for
volatility.
