TO THE SHAREHOLDERS

    We are pleased to provide you with the 1997 Annual Report for Seligman
Henderson Global Fund Series, Inc., which includes Seligman Henderson
International Fund, Seligman Henderson Emerging Markets Growth Fund, Seligman
Henderson Global Growth Opportunities Fund, Seligman Henderson Global Smaller
Companies Fund, and Seligman Henderson Global Technology Fund.

    The Funds had varied investment results for the fiscal year ended October
31, 1997, reflecting the differences in each Fund's investment objective and
regional weightings. Fund-specific information, including investment reports
from the Portfolio Managers, begins on page 3.

    The last 12 months have been challenging. Through October 31, 1997, market
performance was differentiated according to geographic region. Overall, while
the fundamental economic and financial background remained generally supportive
in the Western Hemisphere, the Pacific markets experienced increasing
difficulties. Steady growth continued in the US and the UK, and the core
Continental European economies showed stronger signs of economic recovery.

    On the other hand, Japan continued to experience both economic stagnation
and a weakened equity market, despite a historically low interest rate
environment. A wave of currency devaluations swept through the Southeast Asian
nations, causing sharp corrections in the regional equity markets. While Latin
American markets remained unscathed for a period, the spillover of the
corrections had begun to affect these markets toward the end of the Funds'
fiscal year. A more detailed discussion of economic and market conditions in the
last 12 months appears on page 2.

    Even though the recent volatility in the global equity markets has been
disconcerting, we remain positive on the long-term prospects. The US and the
European stock markets were able to endure a correction and recover in a timely
fashion because of supportive underlying fundamentals. In contrast, the dangers
of excessive growth -- such as what occurred in Southeast Asia -- have become
more clear. Nonetheless, the recent events in Southeast Asia may, over time,
help these governments lay more robust foundations for continued prosperity
based on solid financial, monetary, and fiscal practices.

    Investments in the international markets still play an important part in a
long-term investment strategy and in a diversified portfolio. We do not expect
the current turmoil to reduce the long-term importance of emerging markets, nor
the contributions these nations are projected to make to the global economy in
the next century. We also believe that Seligman Henderson Global Fund Series is
well positioned to benefit from the future growth of the global equity markets.

    This Shareholder Report has been redesigned in conjunction with a corporate
effort to enhance the overall clarity and quality of all communications to our
Shareholders. We hope you find the additional information contained herein
helpful.

    Thank you for your continued support of Seligman Henderson Global Fund
Series. We look forward to serving your global investment needs for many years
to come.

By order of the Board of Directors,

MARKET AND ECONOMIC OVERVIEW

OVERVIEW

    The past 12 months brought exceptionally divergent performances among
regional economies and markets. Generally speaking, economies and stock markets
in the Americas and Europe performed well. In contrast, economies and stock
markets performed poorly in Japan and the broader Pacific region.

UNITED STATES

    In the United States, the generally benign backdrop of steady economic
growth and low inflation continued. Declining bond yields, combined with
satisfactory corporate profit growth, allowed the stock market to continue
pushing ahead despite a correction in October. The US dollar was generally
strong, rising markedly against most major European currencies and the Japanese
yen.

UNITED KINGDOM

    The United Kingdom's economy continued to grow rapidly. Growth was strong
enough to prompt four short-term interest rate increases in attempts to slow the
pace of economic expansion. Inflation remained reasonably low, although it was
not as subdued as in the US. This background led to a strong sterling, which had
some damaging effects on corporate profitability but generally helped improve
returns in US dollar terms.

CONTINENTAL EUROPE

    In Continental Europe, there were growing signs of recovery in the core
economies such as France and Germany. The recovery was led by strong exports,
due to the significant weakness of Continental European currencies against the
US dollar. The domestic corporate consumer, however, has been a bit slower to
recover confidence. European businesses, particularly in Germany, have made
major efforts to restructure, as evidenced by strongly positive corporate profit
figures.

    Progress towards the European Monetary Union (EMU) continued at a rapid
pace, and it now looks likely to begin, as scheduled, in January 1999 with 11
countries participating. The major beneficiaries of EMU have been Italy and
Spain, which have both seen sharp declines in bond market yields. There have
also been some impressive returns in local currency terms, although these were
somewhat dissipated when converted to the US dollar. The best performing markets
were in Spain and Italy, but Switzerland and the Netherlands also provided solid
returns. The French market lagged other Continental European markets, due to
concerns regarding new political and economic reforms.

JAPAN

    The Japanese economy, which looked as though it might be recovering in the
early part of 1997, faltered following the rise in consumption taxes in April.
Economic growth is now virtually non-existent. The authorities have had
difficulties trying to alleviate this problem. The Japanese budget deficit rose
rapidly, and there was political pressure to keep the yen from devaluing too
quickly. Corporate profits, however, continued to do reasonably well, as the
export sector was supported by the weakness of the yen. The banking sector
continued to be hard hit and recently suffered from the problems spilling over
from Southeast Asia. While the stock market rallied in the early part of 1997,
it fell sharply in the third calendar quarter and remains depressed.

PACIFIC REGION

    In the Pacific region, the problems that started in Thailand in the early
part of 1997 gradually spread. Currencies devalued rapidly in Indonesia,
Malaysia, and the Philippines, and more recently, similar problems have spread
to the North with mounting fears in Hong Kong and South Korea. These problems
resulted from a legacy of accelerated growth and rising current account
deficits. Thus far, the reaction of authorities has been ineffective and
difficulties seem likely to persist in the region. In US dollar terms, the
region's stock markets collapsed, with many markets trading 50% below their peak
levels.

EMERGING MARKETS

    It has been a much better period for emerging markets outside the Pacific
region, as stock markets in Latin America and emerging Europe generally
performed well. However, there have been fears recently that the problems seen
in the Pacific region could spread to some of these countries. However, the
economic backgrounds are generally fundamentally stronger than those in the
Pacific region, and we believe these markets should not be as negatively
impacted.

SUMMARY

    In Western markets, economic growth is likely to remain satisfactory and
inflation will probably remain low. However, the problems of the Pacific region,
if allowed to spread, could have more serious consequences for Western markets
than has been the case thus far. The major risk is that continued competitive
devaluations could negatively impact Japan. Many Southeast Asian countries are
seeking to export their way out of trouble, and Western exports could suffer in
comparison. There may already be deflation in the traded goods sector in
Southeast Asia, and there are some risks that this could spread to the West.

    For now, we do not expect the situation to worsen, but it needs to be
carefully monitored. The volatility seen in the global stock markets recently
could well continue in the short term. While market volatility could provide
attractive buying opportunities from time to time, investors should remain
cautious until the problems of the Pacific region and Japan can be more fully
assessed and properly addressed.

INVESTMENT REPORT
SELIGMAN HENDERSON INTERNATIONAL FUND

PERFORMANCE REVIEW

For the 12 months ended October 31, 1997, Seligman Henderson International Fund
posted a total return of 9.83% based on the net asset value of Class A shares,
versus the 10.28% total return of its peers, as measured by the Lipper
International Funds Average, and the 4.92% total return of stocks in the
international markets, as represented by the Morgan Stanley Capital
International EAFE (Europe, Australasia, Far East) Index (MSCI EAFE Index).
Throughout the fiscal year, there was a fair amount of volatility and divergence
in performance across regional markets. Continental Europe enjoyed a
continuation of a strong bull market, with stocks rising nearly 26%. In
contrast, certain markets in the Pacific region declined more than 20%.

PORTFOLIO STRATEGY

UNITED KINGDOM

o   In the United Kingdom, the market was boosted by a stronger sterling, rising
    28.6% for the 12 months ended October 31, 1997. Economic growth has been
    running at an annualized rate of 3.5% to 4.0%, well above trend, and booming
    consumer and service sectors have more than compensated for a struggling
    manufacturing sector.

    DURING THE FISCAL YEAR, WE INCREASED OUR WEIGHTING IN THE UK TO 21.7% FROM
    16.4% 12 MONTHS AGO, AS WE BELIEVED ITS MARKET LOOKED MORE REASONABLY VALUED
    THAN MANY OTHERS IN THE WORLD. OUR STRATEGY HAS BEEN TO FAVOR
    DOMESTIC-ORIENTED STOCKS, SUCH AS Railtrack Group, THE MONOPOLY PROVIDER OF
    RAIL SERVICES.

CONTINENTAL EUROPE

o   In Continental Europe, rising economic growth and low inflation have created
    a favorable backdrop for equity markets. Italy, Spain, and Switzerland
    posted the greatest gains, each rising more than 30% for the 12 months ended
    October 31, 1997. Continental Europe is in an early stage of an economic
    cycle and could see several more years of economic growth and rising
    corporate profits. We believe that the growing popularity of equity
    investing in Continental Europe will also continue to fuel strong cash flows
    into the markets.

    THE FUND'S WEIGHTING IN CONTINENTAL EUROPE, EXCLUDING THE EMERGING EUROPEAN
    MARKETS, WAS INCREASED TO 45.2%, FROM 38.0% 12 MONTHS AGO, AS WE BELIEVE
    THERE IS STILL GOOD LONG-TERM POTENTIAL. WE SEE THE GREATEST PROSPECTS FOR
    FUTURE EARNINGS GROWTH IN CYCLICAL COMPANIES AND CORPORATE RESTRUCTURING
    STORIES, SUCH AS Thyssen IN GERMANY, A MANUFACTURER OF STEEL PRODUCTS.

JAPAN

o   For the 12 months ended October 31, 1997, the Japanese equity market fell
    18.7%. The Japanese economy, which had looked as though it might be
    recovering at the beginning of the calendar year, has been struggling from
    the effects of the consumption tax hike. In addition, while corporate
    profits have held up thus far, the anticipated fall in Japanese exports to
    the Pacific region does not bode well.

    DUE TO THE POOR ECONOMIC AND FINANCIAL BACKGROUND, THE FUND'S WEIGHTING IN
    JAPAN WAS REDUCED TO 15.6% FROM 23.3%

FUND OBJECTIVE

Seligman Henderson International Fund, which commenced investment operations on
April 7, 1992, seeks long-term capital appreciation by investing primarily in
the stocks of larger-sized companies outside the US.

                                                                           -----
                                                                               3

INVESTMENT REPORT
SELIGMAN HENDERSON INTERNATIONAL FUND


    12 MONTHS AGO. WE EXPECT THE MARKET TO REMAIN IN ITS CURRENT TRADING RANGE
    UNTIL ECONOMIC RECOVERY BECOMES MORE CERTAIN. ADDITIONAL FUND ASSETS WILL
    NOT BE COMMITTED TO JAPAN UNTIL THE ECONOMIC ENVIRONMENT IMPROVES MARKEDLY.

PACIFIC REGION

o   Southeast Asian markets have been battered by currency crises. The Thai baht
    was the first currency to experience a devaluation, which then spread
    throughout the Pacific region, provoking an upset in the global equity
    markets. Malaysia, Thailand, and the Philippines were hardest hit, each
    falling more than 50%.

    GIVEN THE ECONOMIC RISKS, WE SUBSTANTIALLY REDUCED THE FUND'S WEIGHTING IN
    THE REGION TO 2.2%, DOWN FROM 15.2% 12 MONTHS AGO. IT MAY TAKE SOME TIME FOR
    GOVERNMENTS TO IMPLEMENT POLICIES THAT WILL RESTORE CONFIDENCE IN THESE
    MARKETS AND ECONOMIES. UNTIL SUCH TIME, WE WILL AVOID ADDITIONAL INVESTMENTS
    IN THIS REGION.

EMERGING MARKETS

o   As for the emerging markets, stock markets generally performed very well.
    Emerging European markets demonstrated the greatest gains, led by Russia,
    which finished up 139.1% for the 12-month period ended October 31, 1997.
    Latin America also posted strong results and, until the global weakness in
    October, contained some of the best-performing markets.

    WE INCREASED THE FUND'S WEIGHTING IN THE EMERGING MARKETS TO 11.8% FROM 5.4%
    AT OCTOBER 31, 1996, AS WE DO NOT EXPECT THE PROBLEMS OF THE PACIFIC REGION
    TO SPREAD TO THESE COUNTRIES BECAUSE THEIR ECONOMIC CLIMATES ARE HEALTHIER.

SUMMARY

Looking forward, the near-term outlook for equity markets remains mixed. The
turmoil in the Pacific region has heightened investors' awareness of the high
valuation levels found in many regions. Furthermore, if the problems seen in the
Pacific region were to spread, this could potentially hinder Continental
Europe's economic recovery and reduce corporate profitability elsewhere in the
world. However, we believe that the problems seen in the Pacific region will be
contained and that the global economy should continue its expansion, with an
eventual recovery in the Pacific region and Japan.

Note: All figures are in US dollar terms. All specific market performance
information included in the Investment Report is taken from the MSCI country
index for the 12-month period ended October 31, 1997, unless otherwise stated.

    Performance data quoted represent changes in prices and assume that all
distributions within the periods are invested in additional shares. The rates of
return will vary and the principal value of an investment will fluctuate.
Shares, if redeemed, may be worth more or less than their original cost.

- ----------
    * Returns for periods of less than one year are not annualized.
   ** Return figures reflect any change in price and assume the investment of
      dividends and capital gain distributions. Returns for Class A shares are
      calculated with and without the effect of the initial 4.75% maximum sales
      charge. Returns for Class A shares also reflect the effect of the service
      fee of up to 0.25% under the Administration, Shareholder Services and
      Distribution Plan after September 21, 1993, only. Returns of Class B
      shares are calculated with and without the effect of the maximum 5%
      contingent deferred sales load ("CDSL"), charged on redemptions made
      within one year of the date of purchase, declining to 1% in the sixth year
      and 0% thereafter. Returns for Class D shares are calculated with and
      without the effect of the 1% CDSL, charged on redemptions made within one
      year of the date of purchase.
  *** The Lipper International Funds Average and the Morgan Stanley Capital
      International EAFE (Europe, Australasia, Far East) Index (MSCI EAFE Index)
      are unmanaged benchmarks that assume reinvestment of dividends. The Lipper
      International Funds Average excludes the effect of sales charges and the
      MSCI EAFE Index excludes the effect of fees and sales charges. The monthly
      performance of the Lipper International Funds Average is used in the
      Performance and Portfolio Overview. Investors cannot invest directly in an
      average or an index.
    + The CDSL is 5% for periods of one year or less, and 4% since inception.
   ++ From March 31, 1992.
  +++ From April 30, 1996.
    # From September 30, 1993.
   ## On November 21, 1997, a capital gain of $1.222 per share was paid to
      shareholders.
  ### Represents the per share amount of net unrealized appreciation of
      portfolio securities as of October 31, 1997.

SELIGMAN HENDERSON INTERNATIONAL FUND

  This chart compares a $10,000 hypothetical investment made in Seligman
Henderson International Fund Class A shares, with and without the initial 4.75%
maximum sales charge, since the commencement of investment operations on April
7, 1992, through October 31, 1997, to a $10,000 hypothetical investment made in
the Lipper International Funds Average and the Morgan Stanley Capital
International EAFE (Europe, Australasia, Far East) Index (MSCIEAFE Index) for
the same period. It is important to keep in mind that the Index excludes the
effect of fees or sales charges, and the Average excludes the effect of sales
charges.

    There are specific risks associated with global investing, such as currency
fluctuations, foreign taxation, differences in financial reporting practices,
and rapid changes in political and economic conditions.

    As shown on page 6, the performances of Class B and D shares will be greater
than or less than the performance shown for Class A shares, based on the
differences in sales charges and fees paid by shareholders. Past performance is
not indicative of future investment results.

INVESTMENT REPORT
SELIGMAN HENDERSON EMERGING MARKETS GROWTH FUND

PERFORMANCE REVIEW

The 12 months ended October 31, 1997, was an extremely volatile period for the
emerging markets, with the most notable event being the currency crisis among
the members of the Association of South East Asian Nations (ASEAN). In the
12-month period, Seligman Henderson Emerging Markets Growth Fund performed
comparatively well, posting a total return of 8.26% based on the net asset value
of Class A shares, against the 3.93% total return of the Lipper Emerging Markets
Funds Average and the -9.74% total return of the Morgan Stanley Capital
International Emerging Markets Free Index (MSCI EMF Index).

Overall, the Fund largely avoided the difficulties of the currency crisis in the
ASEAN markets and made significant advances during the early part of 1997, as
non-ASEAN markets rallied. The Fund, however, was affected by general declines
in the emerging markets during the October weakness in the global equity
markets. Cash levels were gradually increased beginning in September 1997 as
global market uncertainty grew.

PORTFOLIO STRATEGY

PACIFIC REGION

o   The ASEAN currency crisis was caused by a combination of over-valued
    exchange rates, high levels of foreign indebtedness, over-investment in
    property and other unproductive assets, and poor economic management. The
    problems began in Thailand and spread to the other ASEAN economies. Over the
    last 12 months, poor market performance, combined with currency
    devaluations, led to some very large losses in these markets. Thailand fell
    68.9%, Malaysia fell 57.8%, and the Philippines and Indonesia fell 54.8% and
    43.4%, respectively.

    AT OCTOBER 31, 1996, THE FUND HAD A WEIGHTING OF 14.9% IN THE ASEAN MARKETS.
    THIS WEIGHTING WAS REDUCED TO A VERY LOW LEVEL IN JULY 1997, AS THE SEVERITY
    OF THE CRISIS BECAME APPARENT. THE FUND ENDED ITS FISCAL YEAR AT A WEIGHTING
    OF 2.0% IN ASEAN MARKETS, SUBSTANTIALLY LESS THAN THE 13.6% WEIGHTING OF THE
    MSCI EMF INDEX.

o   The Northeast Asian markets generally avoided the problems of the ASEAN
    markets until July 1997, and China and Taiwan provided solid gains. However,
    South Korea's stock market was weak, burdened by poor domestic liquidity.
    The Northeast Asian markets started showing significant weakness in August.
    In October, markets fell sharply as first the Hong Kong dollar, and then the
    South Korean won, were subject to attack. In the 12 months ended October 31,
    1997, the Chinese market gained 20.6%, but the Taiwanese market fell 3.4%
    and South Korea's market fell 46.5%.

    THE FUND'S EXPOSURE TO THE NORTHEAST ASIAN MARKETS OF CHINA, TAIWAN, AND
    SOUTH KOREA WAS REDUCED IN SEPTEMBER AND OCTOBER AND ENDED THE 12-MONTH
    PERIOD AT 14.2%. NONETHELESS, KEY "RED CHIPS" SUCH AS Qingling Motors,
    Huaneng Power International, AND China Everbright, AND TAIWANESE TECHNOLOGY
    STOCKS SUCH AS Synnex Technology International AND Siliconware Precision
    Industries REMAIN IN THE PORTFOLIO. HOWEVER, AFTER OCTOBER 31, 1997, THE
    FUND'S EXPOSURE TO SOUTH KOREA WAS ELIMINATED BEFORE THE CURRENCY
    DEVALUATION AND THE SUBSEQUENT INTERNATIONAL MONETARY FUND PACKAGE.

INVESTMENT REPORT
SELIGMAN HENDERSON EMERGING MARKETS GROWTH FUND

LATIN AMERICA

o   Latin American equity markets continued to benefit from the economic
    recovery that began when the Mexican crisis ended in early 1995. Until the
    world-wide weakness in October 1997, the region contained some of the best
    performing emerging markets. The Brazilian stock market had a strong rally
    in the early part of 1997, due to optimism regarding the country's economic
    reforms. However, this market subsequently experienced sharp declines as
    doubts emerged over the sustainability of the government's currency policy.
    Overall, Brazil was up 14.5% for the 12-month period ended October 31, 1997.
    Mexico and Argentina continued to benefit from economic recovery, following
    the 1994 crisis, and their markets finished the 12-month period ended
    October 31, 1997, up 34.2% and 20.5%, respectively. The Chilean market
    remained pressured by worries over inflation and the currency, and ended the
    period marginally lower.

    THE FUND MAINTAINED ITS YEAR-LONG OVERWEIGHTING IN LATIN AMERICA, WHICH
    IMPROVED THE PORTFOLIO'S OVERALL RESULTS AS THESE MARKETS WERE SOMEWHAT LESS
    IMPACTED BY THE RECENT VOLATILITY IN THE PACIFIC REGION. AT OCTOBER 31,
    1997, THE FUND'S INVESTMENTS WERE FOCUSED IN MEXICO AT 10.3% AND BRAZIL AT
    9.6%, AS THESE ARE BY FAR THE LARGEST MARKETS IN THE REGION. OVERALL, THE
    FUND HAD A WEIGHTING OF 28.7% IN LATIN AMERICA, HAVING STOOD AT 26.7% AT
    OCTOBER 31, 1996. WE PLAN TO MAINTAIN THE FUND'S SUBSTANTIAL INVESTMENT IN
    THIS REGION GOING FORWARD WITH AN ADDITIONAL EMPHASIS ON MEXICO, AS ITS
    ECONOMIC RECOVERY SEEMS ENTRENCHED.

    WITHIN MEXICO, THE PORTFOLIO HAS BEEN INCREASINGLY FOCUSED ON CONSUMER
    STOCKS SUCH AS Grupo Televisa, Femsa, Panamerican Beverages, AND Grupo
    Iusacell, TOGETHER WITH INDUSTRIAL AND EXPORT STOCKS SUCH AS Desc AND ALFA.
    THE BRAZILIAN PORTFOLIO HAS BECOME INCREASINGLY FOCUSED ON PRIVATIZATION
    STOCKS IN THE UTILITIES SECTOR SUCH AS Telebras, CEMIG, AND SABESP.

CENTRAL/SOUTHERN EUROPE

o   Performance in Central/Southern Europe was diverse, reflecting the differing
    outlooks for the economies within the region. The Russian market continued
    to power ahead, bolstered by increasing domestic and foreign investor
    confidence, and finished 139.1% higher for the 12-month period ended October
    31, 1997. The market in Turkey rose 89.1% during the 12-month period on the
    expectation of currency reforms. The Hungarian market improved 84.3%, fueled
    by earlier economic reforms and good domestic liquidity. The Portuguese and
    Greek markets produced more modest returns of 42.8% and 32.2%, respectively.
    In contrast, the Czech market lost 12.6% after a banking crisis, and the
    Polish market fell 11.0% on fears of a currency crisis.

    THE FUND HAD A WEIGHTING OF 18.7% IN CENTRAL/SOUTHERN EUROPE AS OF OCTOBER
    31, 1996, AND HELD A SUBSTANTIAL POSITION IN THE REGION FOR THE LAST 12
    MONTHS. THE FUND HAD A WEIGHTING OF 20.4% IN THE REGION AT OCTOBER 31, 1997,
    AND WILL LIKELY MAINTAIN THIS INVESTMENT LEVEL GOING FORWARD. THE FUND'S
    INVESTMENTS WERE PRINCIPALLY IN MARKETS THAT BENEFITED FROM CONTINUING
    ECONOMIC RECOVERY AND IMPROVING LIQUIDITY, SUCH AS RUSSIA AT 8.6%, PORTUGAL
    AT 4.2%, AND HUNGARY AT 3.0%.

    THE RUSSIAN PORTFOLIO WAS FOCUSED ON OIL AND GAS STOCKS AND FEATURED A LARGE
    HOLDING IN Tatneft, TOGETHER WITH HOLDINGS IN Lukoil Holding AND
    Surgutneftegaz. BOTH THE PORTUGUESE AND HUNGARIAN PORTFOLIOS CONTAINED
    PROMINENT STOCKS, SUCH AS Portugal Telecom IN PORTUGAL, A PROVIDER OF
    TELECOMMUNICATIONS SERVICES, AND MOL Magyar Olaj-es Gazipari IN HUNGARY, AN
    OIL AND GAS PRODUCER AND DISTRIBUTOR.

INDIAN SUBCONTINENT/AFRICA

o    Within the Indian Subcontinent/Africa, market moves were more modest.
     Although Indian interest rates fell and domestic liquidity improved, lack
     of domestic confidence and the absence of an economic upturn limited the
     market's rise to 16.9% in the 12-month period ended October 31, 1997. Among
     the more significant markets, Egypt was the best performer, due to optimism
     over economic reforms. Its market was up 69.3% for the 12 months ended
     October 31, 1997. In contrast, the South African market slid 8.3%, affected
     by high domestic interest rates.

     AT OCTOBER 31, 1997, THE FUND'S WEIGHTING IN THE INDIAN SUBCONTINENT/AFRICA
     STOOD AT 17.4%, PRIMARILY SPLIT BETWEEN INDIA AND SOUTH AFRICA. THIS WAS A
     SLIGHT INCREASE FROM A WEIGHTING OF 13.5% AT OCTOBER 31, 1996. THE INDIAN
     PORTFOLIO WAS DIVERSIFIED WITH THE ADDITION OF Videsh Sanchar Nigam, A
     PROVIDER OF INTERNATIONAL TELECOMMUNICATIONS SERVICES. WITHIN THE SOUTH
     AFRICAN PORTFOLIO, THE FOCUS HAS BEEN ON INDUSTRIAL AND COMMERCIAL STOCKS,
     SUCH AS Metro Cash & Carry, RATHER THAN ON MINERAL PRODUCERS.

SUMMARY

The global equity markets have been exceptionally volatile as the Fund begins
its new fiscal year, due to the possibility of further currency problems. The
recent declines in the markets have created significant opportunities in certain
emerging markets, although recovery in some ASEAN countries may take an extended
period of time. At October 31, 1997, cash levels stood at a defensively high
level of 17.4%. As global markets stabilize, the cash within the Fund will be
invested in markets whose economies have more positive outlooks.

information included in the Investment Report is taken from the MSCI country
index for the 12-month period ended October 31, 1997, unless otherwise stated.

CAPITAL LOSS INFORMATION

FOR THE YEAR ENDED OCTOBER 31, 1997
REALIZED ..................   $(0.190)
UNREALIZED ................    (0.011)#

    Performance data quoted represent changes in prices and assume that all
distributions within the periods are invested in additional shares. The rates of
return will vary and the principal value of an investment will fluctuate.
Shares, if redeemed, may be worth more or less than their original cost.

- ----------
    * Returns for periods of less than one year are not annualized.
   ** Return figures reflect any change in price and assume the investment of
      dividends and capital gain distributions. Returns for Class A shares are
      calculated with and without the effect of the initial 4.75% maximum sales
      charge. Returns of Class B shares are calculated with and without the
      effect of the maximum 5% contingent deferred sales load ("CDSL"), charged
      on redemptions made within one year of the date of purchase, declining to
      1% in the sixth year and 0% thereafter. Returns for Class D shares are
      calculated with and without the effect of the 1% CDSL, charged on
      redemptions made within one year of the date of purchase.
  *** The Lipper Emerging Markets Funds Average and the Morgan Stanley Capital
      International Emerging Markets Free Index (MSCI EMF Index) are unmanaged
      benchmarks that assume reinvestment of dividends. The Lipper Emerging
      Markets Funds Average excludes the effect of sales charges and the MSCI
      EMF Index excludes the effect of fees and sales charges. The monthly
      performance of the Lipper Emerging Markets Funds Average is used in the
      Performance and Portfolio Overview. Investors cannot invest directly in an
      average or an index.
    + The CDSL is 5% for periods of one year or less, and 4% since inception.
   ++ From May 31, 1996.
    # Represents the per share amount of net unrealized depreciation of
      portfolio securities as of October 31, 1997.

SELIGMAN HENDERSON EMERGING MARKETS GROWTH FUND

  This chart compares a $10,000 hypothetical investment made in Seligman
Henderson Emerging Markets Growth Fund, with and without the initial 4.75%
maximum sales charge for Class A shares, with the 4% contingent deferred sales
load ("CDSL") for Class B shares, and without the 1% CDSL for Class D shares,
since the commencement of operations on May 28, 1996, through October 31, 1997,
to a $10,000 hypothetical investment made in the Lipper Emerging Markets Funds
Average and the Morgan Stanley Capital International Emerging Markets Free Index
(MSCI EMF Index) for the same period. It is important to keep in mind that the
Index excludes the effect of fees or sales charges, and the Average excludes the
effect of sales charges.

INVESTMENT REPORT
SELIGMAN HENDERSON GLOBAL GROWTH OPPORTUNITIES FUND

PERFORMANCE REVIEW

For the 12 months ended October 31, 1997, Seligman Henderson Global Growth
Opportunities Fund posted a total return of 13.86% based on the net asset value
of Class A shares, compared to the 16.45% total return of its peers, as measured
by the Lipper Global Funds Average. Stocks around the world, as measured by the
Morgan Stanley Capital International World Index (MSCI World Index), posted a
total return of 17.25% for the period. Given its growth objective, the Fund was
substantially invested in the Pacific region and Latin America, where stocks
with strong earnings growth rates were found. Many of these stocks saw their
valuations reduced in the currency crisis, which contributed to the Fund's
relative underperformance.

The past 12 months offered strikingly differentiated economic and market
performance around the world. While the Americas prospered with continuing
benign surprises regarding growth and inflation, the Pacific region suffered a
significant economic deterioration that culminated in widespread currency
crises. Meanwhile, Continental Europe enjoyed the best increase in economic and
earnings growth as a result of currency devaluation. In each case, stock market
performance reflected these regional developments.

PORTFOLIO STRATEGY

Throughout its fiscal year, the Fund maintained fairly balanced investments
among its four major themes: 32% was invested in PRODUCTIVITY, 30% in QUALITY OF
LIFE, 23% in CONSUMER IS KING; and the smallest portion of the Fund's
investments was in GLOBAL TRADE, which accounted for 15% of the Fund's total
assets.

PRODUCTIVITY

o   A key focus for corporate management around the world continued to be the
    search for improved productivity and reduced costs. Greater investment in
    technology and an acceleration in outsourcing were two popular methods for
    achieving those goals.

    AS A RESULT, SOME OF THE MOST SUCCESSFUL INVESTMENTS IN THE FUND WERE
    RELATED TO THE PRODUCTIVITY THEME, SPECIFICALLY STOCKS IN THE Technology AND
    Outsourcing SUB-THEMES. FOR EXAMPLE, ALL THE FOLLOWING PROVED TO BE STRONG
    PERFORMERS: Microsoft IN THE UNITED STATES, A PRODUCER OF MICROCOMPUTER
    SOFTWARE; L.M. Ericsson Telefon IN SWEDEN, A MANUFACTURER OF
    TELECOMMUNICATIONS EQUIPMENT; AND Parity IN THE UNITED KINGDOM, A PROVIDER
    OF SOFTWARE ENGINEERING AND CONSULTING SERVICES.

QUALITY OF LIFE

o   This area provided some of the most exciting sub-themes for finding growth
    stocks, particularly in the Health Care and Tourism sub-themes.

    IN Health Care, TWO OF THE BIGGEST WINNERS IN THE PAST 12 MONTHS INCLUDED
    Pfizer IN THE US AND Richter Gedeon IN HUNGARY. BOTH PHARMACEUTICAL STOCKS
    PRODUCED BETTER-THAN-EXPECTED EARNINGS GROWTH. WE ALSO PURCHASED Genset, A
    LEADING BIOMEDICAL RESEARCH COMPANY BASED IN FRANCE. Genset IS MAPPING THE

FUND OBJECTIVE

Seligman Henderson Global Growth Opportunities Fund, which commenced operations
on November 1, 1995, seeks long-term capital appreciation by investing primarily
in the stocks of companies that have the potential to benefit from global
economic or social trends.

INVESTMENT REPORT
SELIGMAN HENDERSON GLOBAL GROWTH OPPORTUNITIES FUND


    HUMAN GENE WITH THE OBJECTIVE OF USING THE GENOMIC DATABASE TO IMPROVE THE
    EFFICIENCY OF CLINICAL TRIALS FOR NEW DRUGS.

    IN Tourism, CHEAPER CURRENCIES AND GREATER ECONOMIC ACTIVITY HAVE BEEN THE
    MAJOR FACTORS SUPPORTING THE INDUSTRY. RISING TRAFFIC AND HIGHER OCCUPANCY
    RATES ARE RAISING THE EARNINGS PROFILE OF THESE COMPANIES. THROUGHOUT THE
    FISCAL YEAR, WE CONTINUED TO ADD STOCKS RELATED TO EUROPEAN TOURISM, SUCH AS
    Airtours IN THE UK, A TOUR OPERATOR.

CONSUMER IS KING

o   While consumption was strong in the US and the UK during the past 12 months,
    it was disappointing elsewhere. However, improving consumer confidence in
    Continental Europe held promise for the future. Despite a mixed background,
    there were many pockets of buoyant consumption.

    IN PARTICULAR, THE FUND'S Global Brand Power SUB-THEME WAS MOST REWARDING.
    TWO GERMAN COMPANIES -- Adidas, A MANUFACTURER OF SPORTING GOODS, AND
    Porsche, A MANUFACTURER OF LUXURY SPORTS CARS -- ENJOYED RAPIDLY GROWING
    DEMAND, THE RESULT OF AGGRESSIVE PRODUCT STRATEGIES AND IMPRESSIVE
    EXECUTION.

GLOBAL TRADE

o   Although GLOBAL TRADE continued to grow at a faster pace than global
    economic growth, we found few obvious direct beneficiaries. Instead, we
    concentrated on the Telecommunications and Natural Resources sub-themes,
    which led us mostly to the emerging markets. While in developed markets such
    businesses are normally mature, with slow earnings growth, in many
    developing countries both sectors can enjoy rapid growth. For example, as
    these countries become wired, telephone traffic should soar. Similarly, more
    efficient use of Latin America's and Eastern Europe's vast natural resources
    should result in rapid earnings growth.

    WITH THIS IN MIND, WE INVESTED IN TELECOMMUNICATIONS COMPANIES IN INDIA,
    BRAZIL, AND MEXICO. WE WERE ALSO LED TO OIL AND GAS COMPANIES IN BRAZIL,
    HUNGARY, AND RUSSIA. OVER THE 12-MONTH PERIOD, THE FUND'S WEIGHTING IN THE
    EMERGING MARKETS INCREASED SLIGHTLY FROM 8.5% TO 10.0% AT OCTOBER 31, 1997.

JAPAN AND THE PACIFIC REGION

o   The Fund's biggest disappointments during the past 12 months were in Japan
    and the Pacific region. In Japan, the Fund's emphasis on attractively valued
    mid-capitalization growth stocks was not particularly rewarding, as nervous
    investors continued to seek safety in large-capitalization stocks despite
    their lofty valuations. In the Pacific region, we de-emphasized property and
    bank stocks in favor of technology and consumer staples. However, in the
    recent turmoil, even these sectors saw indiscriminate reductions in
    valuations.

    OVERALL, THE FUND'S EXPOSURE TO JAPAN WAS REDUCED TO 9.6% FROM 16.6% 12
    MONTHS AGO. WITH LITTLE IMPROVEMENT IN SIGHT, WE SIGNIFICANTLY REDUCED THE
    FUND'S EXPOSURE TO THE PACIFIC REGION OVER THE PAST 12 MONTHS, FROM 11.2% TO
    4.6% AT OCTOBER 31, 1997.

SUMMARY

The near-term outlook for global equity markets remains uncertain. Recent market
volatility is a result of the heightened economic and valuation risks perceived
to exist around the world. The economic shocks emanating from the Pacific region
could reduce the outlook for economic and earnings growth worldwide.

However, the slowdown in the Pacific region could prove disinflationary for the
US, the UK, and Continental Europe. Therefore, we do not believe that the US
Federal Reserve Board or the German Bundesbank will need to raise interest rates
in the very near term. Looking forward, we continue to believe that Continental
Europe has the strongest future growth prospects. Accordingly, the Fund's
largest weighting is in this region with 32.8% at October 31, 1997, (excluding
Hungary which is an emerging market), significantly higher than the 25.7%
weighting at October 31, 1996.

We believe that the current environment of worldwide excess capacity and low
pricing power could make profit margins more vulnerable and earnings expansion
more prized. Growth stocks should then command a higher premium. Our thematic
investment approach is designed to find such rewarding growth opportunities, and
we will continue to apply this discipline in the year ahead.

Note: All figures are in US dollar terms. All specific market performance
information included in the Investment Report is taken from the MSCI country
index for the 12-month period ended October 31, 1997, unless otherwise stated.

PERFORMANCE AND PORTFOLIO OVERVIEW                              October 31, 1997
SELIGMAN HENDERSON GLOBAL GROWTH OPPORTUNITIES FUND

    This chart compares a $10,000 hypothetical investment made in Seligman
Henderson Global Growth Opportunities Fund, with and without the initial 4.75%
maximum sales charge for Class A shares, and without the 1% contingent deferred
sales load ("CDSL") for Class D shares, since the commencement of investment
operations on November 1, 1995, through October 31, 1997, to a $10,000
hypothetical investment made in the Lipper Global Funds Average and the Morgan
Stanley Capital International World Index (MSCI World Index) for the same
period. It is important to keep in mind that the Index excludes the effect of
fees or sales charges, and the Average excludes the effect of sales charges.

    There are specific risks associated with global investing, such as currency
fluctuations, foreign taxation, differences in financial reporting practices,
and rapid changes in political and economic conditions.

    As shown on page 24, the performance of Class B shares will be greater than
or less than the performances shown for Class A shares and Class D shares, based
on the differences in sales charges and fees paid by shareholders. Past
performance is not indicative of future investment results.

INVESTMENT REPORT
SELIGMAN HENDERSON GLOBAL SMALLER COMPANIES FUND

PERFORMANCE REVIEW

Seligman Henderson Global Smaller Companies Fund posted a total return of 8.28%
based on the net asset value of Class A shares for the 12 months ended October
31, 1997. In the same period, the Fund's peers, as measured by the Lipper Global
Small Cap Funds Average, had a total return of 11.43%. This compares to a total
return of 13.36% for small-capitalization stocks as a group, as represented by
the Salomon Brothers World Extended Market Index (Salomon Brothers World EM
Index).

The relative underperformance of the Fund was a result of its underweighted
position in the United States, its larger exposure to Japan, and its policy of
focusing investments in developed rather than emerging markets.

Throughout the fiscal year, investors were focused on liquid issues, which tend
to be large-capitalization stocks. As a result, small-cap stocks underperformed
relative to large-cap stocks. Nonetheless, there were periods of regional
small-cap outperformance -- the first calendar quarter of 1997 in the United
Kingdom and the second and third calendar quarters of 1997 in the United States.
October proved to be the most volatile month for world equities in a decade, as
equity markets everywhere experienced important declines as a result of the
currency crisis in the Pacific region.


PORTFOLIO STRATEGY

UNITED STATES

o    In the US, the stock market was fueled by higher-than-expected economic
     growth and corporate earnings, with lower-than-expected inflation. This
     environment favored large-cap stocks. However, beginning in May, small-cap
     stocks' favorable earnings reports began to be noticed. This, combined with
     their lower valuations, shifted the spotlight onto the small-cap arena.
     Small-caps began to outperform large-caps, with sustained outperformance
     beginning in August.

     THE FUND'S WEIGHTING IN THE US INCREASED FROM 30.0% 12 MONTHS AGO TO A
     CURRENT WEIGHTING OF 42.7%. OVER THE FISCAL YEAR, WE CONTINUED TO EMPHASIZE
     THE BUSINESS SERVICES INDUSTRY, DUE TO CORPORATE AMERICA'S GROWING RELIANCE
     ON OUTSOURCING. AS THE ECONOMIC EXPANSION CREATED NEW JOB OPPORTUNITIES, WE
     ALSO INCREASED OUR POSITIONS IN COMPANIES THAT PROVIDE TEMPORARY STAFFING
     SERVICES, ADDING TO AccuStaff AND INVESTING IN Alternative Resources.

UNITED KINGDOM

o    In the UK, the equity market had much to digest in the last 12 months: the
     first change in government in 18 years; a strong currency; and rising
     interest rates. Sterling's strength in the first calendar quarter of 1997
     dampened the performance of large-cap stocks more than that of
     domestically-oriented small-cap issues. From April through the end of
     October 1997, however, the performance of small-cap stocks was
     disappointing.

     HAVING INCREASED THE FUND'S EXPOSURE TO THE UK AT THE END OF 1996, THE FUND
     BENEFITED FROM THE RALLY THAT TOOK PLACE AT THE BEGINNING OF 1997. WE
     CONTINUED TO EMPHASIZE COMPANIES WITH ABOVE-MARKET EARNINGS GROWTH, ADDING
     Games Workshop Group, A MANUFACTURER AND RETAILER OF SPECIALTY GAMES, AND
     Electronics Boutique, A RETAILER OF ELECTRONIC GAMES. AT OCTOBER 31, 1997,
     THE FUND'S WEIGHTING IN THE UK STOOD AT 18.2%, COMPARED TO 14.3% 12 MONTHS
     AGO.

INVESTMENT REPORT
SELIGMAN HENDERSON GLOBAL SMALLER COMPANIES FUND


CONTINENTAL EUROPE

o    In Continental Europe, investors focused on large, multinational companies,
     which consequently outperformed small companies during the Fund's fiscal
     year. Even so, small-cap stocks in this region have offered attractive
     returns, gaining 18.0% in the 12 months ended October 31, 1997.

     AS ECONOMIC MOMENTUM MOVES FROM THE EXPORT SECTORS TO THE DOMESTIC SECTORS
     OF THESE ECONOMIES, THE LOWER VALUATIONS AND HIGHER EARNINGS POTENTIAL OF
     SMALL-CAPS SHOULD BEGIN TO ATTRACT MORE INVESTOR ATTENTION. CONCERNS ABOUT
     THE IMPACT OF THE PROBLEMS IN THE PACIFIC REGION ON THE EXPORT EARNINGS OF
     LARGE COMPANIES SHOULD ALSO SUPPORT SMALLER COMPANIES. AT OCTOBER 31, 1997,
     THE FUND HAD A WEIGHTING OF 25.7% IN CONTINENTAL EUROPE, VIRTUALLY
     UNCHANGED FROM 26.5% ON OCTOBER 31, 1996. WE PLAN TO CONTINUE EMPHASIZING
     THIS REGION IN THE YEAR AHEAD.

JAPAN

o    The index for smaller companies in Japan fell 34.0% in the past 12 months.
     This compares to a decline in the main market index, the Nikkei, of 24.0%.
     Confidence in Japan's economic recovery evaporated as the year progressed
     and was further hindered by the imposition of a higher consumption tax.
     This particularly affected the more domestically-oriented small-cap stocks.

     THE FUND'S WEIGHTING IN JAPAN, WHICH WAS 17.8% AT OCTOBER 31, 1996,
     DECLINED TO 8.2% BY OCTOBER 31, 1997. NEW PURCHASES FOCUSED ON THE MORE
     DEFENSIVE SECTORS OF THE MARKET SUCH AS HEALTH CARE AND FOOD-RELATED
     STOCKS, AND INCLUDED Fujicco, Hogy Medical, Sundrug, AND Yokohama Reito.

PACIFIC REGION

o    In the Pacific region, equity markets rose during the first six months of
     the Fund's fiscal year. However, the devaluation of the Thai baht
     precipitated a crisis that spread throughout the region in the second half
     of the Fund's fiscal year, resulting in substantial reductions in the
     prices of large and small companies alike.

     WE BEGAN TO SIGNIFICANTLY REDUCE THE FUND'S WEIGHTING IN THE PACIFIC REGION
     IN JUNE 1997, AND IT NOW STANDS AT 2.4% FROM 7.1% 12 MONTHS AGO.

SUMMARY

Globally, smaller companies have lower valuations and stronger projected
earnings growth than larger companies. The unpopularity of small companies in
the last 12 months reflected investors' preoccupation with liquidity and concern
that, in an era of low inflation, large companies would tend to have more
pricing power. However, we believe that the fundamentals of smaller companies
will eventually attract investor attention. This certainly happened in the US,
where smaller companies outperformed in May, August, and September. Further, in
the market turmoil of October, smaller companies did not decline as much as
large companies. While it is doubtful that this outperformance represents a
sentiment change toward smaller companies, we continue to believe that the
attractive valuations of smaller companies will eventually be recognized.

Note: All figures are in US dollar terms. All specific market performance
information included in the Investment Report is taken from the Salomon Brothers
World EM country index for the 12-month period ended October 31, 1997, unless
otherwise stated.

  Performance data quoted represent changes in prices and assume that all
distributions within the periods are invested in additional shares. The rates of
return will vary and the principal value of an investment will fluctuate.
Shares, if redeemed, may be worth more or less than their original cost.

- --------------------------------------------------------------------------------
    * Returns for periods of less than one year are not annualized.
   ** Return figures reflect any change in price and assume the investment of
      dividends and capital gain distributions. Returns for Class A shares are
      calculated with and without the effect of the initial 4.75% maximum sales
      charge. Returns of Class B shares are calculated with and without the
      effect of the maximum 5% contingent deferred sales load ("CDSL"), charged
      only on redemptions made within one year of the date of purchase,
      declining to 1% in the sixth year and 0% thereafter. Returns for Class D
      shares are calculated with and without the effect of the 1% CDSL, charged
      only on redemptions made within one year of the date of purchase.
  *** The Lipper Global Small Cap Funds Average, the Morgan Stanley Capital
      International World Index (MSCI World Index), and the Salomon Brothers
      World Extended Market Index (Salomon Brothers World EM Index) are
      unmanaged benchmarks that assume reinvestment of dividends. The Lipper
      Global Small Cap Funds Average excludes the effect of sales charges, and
      the MSCI World Index and the Salomon Brothers World EM Index exclude the
      effect of fees and sales charges. The monthly performance of the Lipper
      Global Small Cap Funds Average is used in the Performance and Portfolio
      Overview. Investors cannot invest directly in an average or an index.
    + The CDSL is 5% for periods of one year or less, and 4% since inception.
   ++ From August 31, 1992.
  +++ From April 30, 1996.

PERFORMANCE AND PORTFOLIO OVERVIEW                              October 31, 1997
SELIGMAN HENDERSON GLOBAL SMALLER COMPANIES FUND

    This chart compares a $10,000 hypothetical investment made in Seligman
Henderson Global Smaller Companies Fund Class A shares, with and without the
initial 4.75% maximum sales charge, since the commencement of investment
operations on September 9, 1992, through October 31, 1997, to a $10,000
hypothetical investment made in the Lipper Global Small Cap Funds Average, the
Morgan Stanley Capital International World Index (MSCI World Index), and the
Salomon Brothers World Extended Market Index (Salomon Brothers World EM Index)
for the same period. It is important to keep in mind that the Indices exclude
the effect of fees or sales charges, and the Average excludes the effect of
sales charges.

    Seligman Henderson Global Smaller Companies Fund will no longer be compared
to the MSCI World Index after October 31, 1997, as this index measures the
performance of more than 1,460 securities around the world, with capitalizations
of all sizes. Your Fund invests primarily in smaller companies and the Manager
believes that the Salomon Brothers World EM Index is a more appropriate
benchmark for your Fund, as it reflects the performance of small-capitalization
stocks. The Salomon Brothers World EM Index reflects the performance of the
bottom 20% capitalizations within the Salomon Brothers World Broad Market Index,
which represents the universe of global securities with market capitalizations
greater than US $100 million. Therefore, your Fund will continue to be compared
to the Salomon Brothers World EM Index and the Lipper Global Small Cap Funds
Average.

    There are specific risks associated with global investing, such as currency
fluctuations, foreign taxation, differences in financial reporting practices,
and rapid changes in political and economic conditions.

    As shown on page 34, the performances of Class B and D shares will be
greater than or less than the performance shown for Class A shares, based on the
differences in sales charges and fees paid by shareholders. Past performance is
not indicative of future investment results.

INVESTMENT REPORT
SELIGMAN HENDERSON GLOBAL TECHNOLOGY FUND

PERFORMANCE REVIEW

For the 12 months ended October 31, 1997, Seligman Henderson Global Technology
Fund performed strongly, posting a total return of 33.86% based on the net asset
value of Class A shares, compared to the 16.45% total return of its peers, as
measured by the Lipper Global Funds Average. Stocks around the world, as
measured by the Morgan Stanley Capital International World Index (MSCI World
Index), posted a total return of 17.25% for the period.

Overall, healthy rates of economic growth and benign inflationary pressures
provided a supportive framework for equity markets during the Fund's fiscal
year. Although market volatility increased markedly in the last six months,
stock prices continued to appreciate until October, when markets, including
technology stocks, fell sharply.

In general, the past 12 months were distinguished by a polarization in the
performance of the United States and European markets versus those in the
Pacific region. While the former produced outstanding returns, the latter fell
sharply. With the exception of the United Kingdom, technology stocks generally
outperformed in the equity markets.


PORTFOLIO STRATEGY

COMPUTING AND SEMICONDUCTORS

o   Perhaps the most notable feature of the technology sector's performance was
    a sharp recovery in the semiconductor industry. Following a difficult period
    in 1996, semiconductor stocks soared, with semiconductor production
    equipment makers leading the way. The personal computer industry showed
    continued strong growth with the top producers gaining significant market
    share.

    THE US PORTION OF THE FUND'S PORTFOLIO PERFORMED STRONGLY, BENEFITING FROM
    ITS HEAVY WEIGHTING IN THE SEMICONDUCTOR PRODUCTION EQUIPMENT AND DATA
    STORAGE AREAS. THE FUND HAD A US WEIGHTING OF 56.5% AT OCTOBER 31, 1997,
    HAVING STOOD AT 55.7% ON OCTOBER 31, 1996.

COMMUNICATIONS

o   The wireless communications industry benefited from both the increased
    demand for infrastructure and the end of the inventory adjustment phase that
    had plagued the industry in 1995 and 1996. The "Year 2000" problem ensured a
    very strong market for both software products and consulting companies,
    while producing growing demand for enterprise storage suppliers. In
    contrast, networking companies saw a slowdown in growth from the dizzying
    levels achieved in previous years. As a result, related sub-sectors, such as
    networking distribution, posted very mixed results.

    THE FUND ENJOYED EXCELLENT PERFORMANCE FROM ITS HEAVY WEIGHTING IN
    INFORMATION TECHNOLOGY CONSULTING STOCKS, AND FROM A WELL-TIMED EXIT FROM
    THE US NETWORKING SECTOR EARLY IN 1997. HOWEVER, THESE GAINS WERE PARTLY
    COUNTERED BY WEAKNESS IN UK AND CONTINENTAL EUROPEAN NETWORKING STOCKS.

PACIFIC REGION

o   The Fund's weighting in the Pacific region remained modest throughout the
    fiscal year, reflecting our concerns about the economic fundamentals and
    outlook, and the valuations of companies.

FUND OBJECTIVE

Seligman Henderson Global Technology Fund, which commenced operations on May 23,
1994, seeks long-term capital appreciation by investing in securities of
companies around the world that operate in the technology and technology-related
industries.
- --------------------------------------------------------------------------------

                                                                           -----
                                                                              49

INVESTMENT REPORT
SELIGMAN HENDERSON GLOBAL TECHNOLOGY FUND

    THE FUND NEVERTHELESS ACHIEVED GOOD RETURNS FROM ITS PORTFOLIO OF JAPANESE
    COMPANIES AND OUTSTANDING PERFORMANCE FROM ITS HOLDINGS IN TAIWAN, BEFORE
    THE WEIGHTING WAS SHARPLY REDUCED DURING THE SUMMER. THE FUND'S JAPAN
    WEIGHTING STOOD AT 8.2% ON OCTOBER 31, 1997, DOWN FROM 10.0% 12 MONTHS AGO.
    THE FUND'S WEIGHTING IN THE PACIFIC REGION WAS 6.7% ON OCTOBER 31, 1997,
    SLIGHTLY HIGHER THAN THE 4.9% ON OCTOBER 31, 1996.


SUMMARY

It is not yet clear how serious the impact of the problems in the Pacific region
will be on demand for technology-based products. However, it is likely that
demand for PCs, peripherals, components, and wireless equipment will be
impacted. Over the next few quarters, companies' future earnings will be harder
to predict.

Nevertheless, many areas of the technology industry should be unaffected by the
problems in the Pacific region. Within the Fund, we plan to emphasize
sub-sectors, such as software, storage, computer and business services, and
medical products and technology. The Fund's exposure to the Pacific region is
not likely to be increased, despite the substantial price declines in those
markets. Instead, the Fund's portfolio will be focused on domestically-oriented
technology companies based in the US, the UK, and Continental Europe.

We expect the recent pattern of market volatility to continue, but believe that
any slowdown in the overall rate of corporate profit growth will highlight the
superior growth potential of the technology sector. In a deflationary
environment, companies could be obliged to sustain profit growth by reducing
costs through the implementation of technology. Technology spending should
therefore remain buoyant, and we anticipate strong relative share price
performance from select stocks.

Note: All figures are in US dollar terms. The following indices were used to
evaluate regional performance for the 12-month period ended October 31, 1997:
Datastream US Pacific Stock Exchange Index, Datastream UK Electronics Index,
Datastream Europe ex-UK Electronics Index (does not include the UK), Datastream
Japan Electronics Index, Datastream Asian Electronics Index, and Datastream
Pacific Basin Electronics Index.

  Performance data quoted represent changes in prices and assume that all
distributions within the periods are invested in additional shares. The rates of
return will vary and the principal value of an investment will fluctuate.
Shares, if redeemed, may be worth more or less than their original cost.


- --------------------
    * Returns for periods of less than one year are not annualized.
   ** Return figures reflect any change in price and assume the investment of
      dividends and capital gain distributions. Returns for Class A shares are
      calculated with and without the effect of the initial 4.75% maximum sales
      charge. Returns of Class B shares are calculated with and without the
      effect of the maximum 5% contingent deferred sales load ("CDSL"), charged
      on redemptions made within one year of the date of purchase, declining to
      1% in the sixth year and 0% thereafter. Returns for Class D shares are
      calculated with and without the effect of the 1% CDSL, charged on
      redemptions made within one year of the date of purchase.
  *** The Lipper Global Funds Average and the Morgan Stanley Capital
      International World Index (MSCI World Index) are unmanaged benchmarks that
      assume reinvestment of dividends. The Lipper Global Funds Average excludes
      the effect of sales charges and the MSCIWorld Index excludes the effect of
      fees and sales charges. The monthly performance of the Lipper Global Funds
      Average is used in the Performance and Portfolio Overview. Investors
      cannot invest directly in an average or an index.
    + The CDSL is 5% for periods of one year or less, and 4% since inception.

  This chart compares a $10,000 hypothetical investment made in Seligman
Henderson Global Technology Fund, with and without the initial 4.75% maximum
sales charge for Class A shares, and without the 1% contingent deferred sales
load ("CDSL") for Class D shares, since the commencement of operations on May
23, 1994, through October 31, 1997, to a $10,000 hypothetical investment made in
the Lipper Global Funds Average and the Morgan Stanley Capital International
World Index (MSCI World Index) for the same period. It is important to keep in
mind that the Index excludes the effect of fees or sales charges, and the
Average excludes the effect of sales charges.

  There are specific risks associated with global investing, such as currency
fluctuations, foreign taxation, differences in financial reporting practices,
and rapid changes in political and economic conditions.

  As shown on page 52, the performance of Class B shares will be greater than or
less than the performances shown for Class A shares and Class D shares, based
on the differences in sales charges and fees paid by shareholders.  Past 
performance is not indicative of future investment results.

operations prior to their commencements on November 1, 1995, and May 28, 1996,
respectively, other than those relating to organizational matters. Each Series
of the Fund offers three classes of shares. All shares existing prior to the
commencement of Class D shares (May 3, 1993, in the case of the Global Smaller
Companies Fund, and September 21, 1993, in the case of the International Fund)
were classified as Class A shares. The Fund began offering Class B shares on
April 22, 1996, for the then existing Series.

    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 load ("CDSL") 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 CDSL, 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. 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 CDSL, if applicable, of 1% imposed on redemptions made
within one year of purchase. The three classes of shares for each Series
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 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 generally accepted accounting principles 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 -- Securities traded on a foreign exchange or
    over-the-counter market are valued at the last sales price on the primary
    exchange or market on which they are traded. United Kingdom securities and
    securities for which there are no recent sales transactions are valued based
    on quotations provided by primary market makers in such securities. Other
    securities not listed on an exchange or security market, or securities in
    which there were no transactions, are valued at the mean of the most recent
    bid and asked prices. Any securities for which recent market quotations are
    not readily available are valued at fair value determined in accordance with
    procedures approved by the Board of Directors. Short-term holdings which
    mature in more than 60 days are valued at current market quotations.
    Short-term holdings maturing in 60 days or less are valued at amortized
    cost.

b.  FOREIGN SECURITIES -- Investments in foreign securities will primarily be
    traded in foreign currencies, and each Series may temporarily hold funds in
    foreign currencies. The books and records of the Fund are maintained in US
    dollars. Foreign currency amounts are translated into US dollars on the
    following basis:

    (i) market value of investment securities, other assets, and liabilities, at
        the daily rate of exchange as reported by a pricing service;

    (ii) purchases and sales of investment securities, income, and expenses, at
        the rate of exchange prevailing on the respective dates of such
        transactions.

    The Fund's net asset values per share will be affected by changes in
currency exchange rates. Changes in foreign currency exchange rates may also
affect the value of dividends and interest earned, gains and losses realized on
sales of securities, and net investment income and gains, if any, which are to
be distributed to shareholders of the Fund. The rate of exchange between the US
dollar and other currencies is determined by the forces of supply and demand in
the foreign exchange markets.

    Net realized foreign exchange gains and losses arise from sales of portfolio
securities, sales and maturities of short-term securities, sales of foreign
currencies, currency gains or losses realized between the trade and settlement
dates on securities transactions, and the difference between the amounts of
dividends, interest, and foreign withholding taxes recorded on the Fund's books,
and the US dollar equivalents of the amounts actually received or paid. Net
unrealized foreign exchange gains and losses arise from changes in the value of
portfolio securities and other foreign currency denominated assets and
liabilities at period end, resulting from changes in exchange rates.

    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


- ------

================================================================================
NOTES TO FINANCIAL STATEMENTS

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.  FORWARD CURRENCY CONTRACTS -- The Fund may enter into forward currency
    contracts in order to hedge its exposure to changes in foreign currency
    exchange rates on its foreign portfolio holdings, or other amounts
    receivable or payable in foreign currency. A forward contract is a
    commitment to purchase or sell a foreign currency at a future date at a
    negotiated forward rate. Certain risks may arise upon entering into these
    contracts from the potential inability of counterparties to meet the terms
    of their contracts. The contracts are valued daily at current exchange rates
    and any unrealized gain or loss is included in net unrealized appreciation
    or depreciation on translation of assets and liabilities denominated in
    foreign currencies and forward currency contracts. The gain or loss, if any,
    arising from the difference between the settlement value of the forward
    contract and the closing of such contract, is included in net realized gain
    or loss from foreign currency transactions.

d.  FEDERAL TAXES -- There is no provision for federal income tax. Each Series
    has elected to be taxed as a regulated investment company and intends to
    distribute substantially all taxable net income and net gain realized, if
    any, annually. Withholding taxes on foreign dividends and interest have been
    provided for in accordance with the Fund's understanding of the applicable
    country's tax rules and rates.

e.  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 dividends.
    Interest income is recorded on an accrual basis.

f.  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 attributed to a
    particular class, are charged directly to such class. For the year ended
    October 31, 1997, distribution and service fees were the only class-specific
    expenses.

g.  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 primarily are
    caused by differences in the timing of the recognition of certain components
    of income, expense, or realized capital gain; and the recharacterization of
    foreign exchange gains or losses to either ordinary income or realized
    capital gains 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 reclassifications will have no effect on net assets, results of
    operations, or net asset value per share of the Fund.

3. PURCHASES AND SALES OF SECURITIES-- Purchases and sales of portfolio
securities, excluding short-term investments, for the year ended October, 31,
1997, were as follows:

purposes was substantially the same as the cost for financial reporting
purposes, and the tax basis gross unrealized appreciation and depreciation of
portfolio securities, including the effects of foreign currency translations,

other Series' average daily net assets, of which 1.15% and 0.90%, respectively,
are paid to the Subadviser.

Global Technology Fund ..............        210,590             1,713,143

     Each Series of 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 year
ended October 31, 1997, fees incurred by the International Fund, the Emerging
Markets Growth Fund, the Global Growth Opportunities Fund, the Global Smaller
Companies Fund, and the Global Technology Fund aggregated $101,145, $88,081,
$270,908, $997,468, and $1,450,470, respectively, or 0.20%, 0.23%, 0.24%, 0.24%,
and 0.25%, respectively, per annum of the average daily net assets of Class A
shares.

     Under the Plan, with respect to Class B 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 and Class D shares for which the organizations are
responsible; and, for Class D shares only, 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 substantially all
of 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 year ended October 31, 1997, fees incurred under the Plan,
equivalent to 1% per annum of the average daily net assets of Class B and Class
D shares, were as follows:

    The Distributor is entitled to retain any CDSL imposed on redemptions of
Class D shares occurring within one year of purchase and on certain redemptions
of Class Ashares occurring within 18 months of purchase. For the year ended
October 31, 1997, such charges were as follows:

shares described above, the Distributor receives payments from the Purchaser
based on the value of Class B shares sold. The aggregate amounts of such
payments and the Class B shares distribution fees retained by the Distributor
for the year ended October 31, 1997, were as follows:

Global Technology Fund                         2,355,588

    Certain officers and directors of the Fund are officers or directors of the
Manager, the Subadviser, 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 fees. Interest is accrued on the deferred
balances. Deferred fees and the related accrued interest are not deductible for
federal income tax purposes until such amounts are paid. The annual cost of such
fees and interest is included in directors' fees and expenses, and the following
accumulated balances thereof at October 31, 1997 are included in other
liabilities:

     SERIES                                       AMOUNT

5. COMMITTED LINE OF CREDIT -- The Fund has a $100 million committed line of
credit facility with a group of banks. Borrowings pursuant to the credit
facility are subject to interest at a rate equal to the federal funds rate plus
0.50% per annum. The Fund incurs a commitment fee of 0.10% per annum on 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 one year from the date of
the agreement but is renewable with the consent of the participating banks. To
date, the Fund has not borrowed from the credit facility.

6. LOSS CARRYFORWARD -- In accordance with current federal income tax law, each
of the Series' net realized capital gains and losses are considered separately
for purposes of determining taxable capital gains. At October 31, 1997, the
Emerging Markets Growth Fund had a net capital loss carryforward for federal
income tax purposes of $3,465,552, which is available for offset against future
taxable capital gains, expiring in various amounts through 2005. Accordingly, no
capital gain distributions are expected to be paid to shareholders until net
capital gains have been realized in excess of the available capital loss
carryforward.


7. AFFILIATED ISSUERS -- As defined under the Investment Company Act of 1940, as
amended, affiliated issuers are those issuers in which a Series' holdings
represent 5% or more of the outstanding voting securities. A summary of the
Fund's transactions in the securities of these issuers during the year ended
October 31, 1997 is as follows:

FINANCIAL HIGHLIGHTS


    The Fund's financial highlights are presented below. "Per share operating
performance" data is designed to allow investors to trace the operating
performance of each Class, on a per share basis, from the beginning net asset
value to the ending net asset value, so that investors can understand what
effect the individual items have on their investment, assuming it was held
throughout the period. Generally, the per share amounts are derived by
converting the actual dollar amounts incurred for each item, as disclosed in the
financial statements, to their equivalent per share amounts based on average
shares outstanding.

    "Total return based on net asset value" measures each Class's performance
assuming that investors purchased Fund shares at net asset value as of the
beginning of the period, invested dividends and capital gains paid at net asset
value, and then sold their shares at the net asset value on the last day of the
period. The total return computations do not reflect any sales charges investors
may incur in purchasing or selling shares of each Series. Total returns for
periods of less than one year are not annualized.

    "Average commission rate paid" represents the average commissions paid by
each Series to purchase or sell portfolio securities. It is determined by
dividing the total commission dollars paid by the number of shares purchased and
sold during the period for which the commissions were paid. This rate is
provided for the periods beginning November 1, 1995.

REPORT OF INDEPENDENT AUDITORS

- --------------------------------------------------------------------------------
THE BOARD OF DIRECTORS AND SHAREHOLDERS,
SELIGMAN HENDERSON GLOBAL FUND SERIES, INC.:

We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments, of the International Fund, the Emerging Markets
Growth Fund, the Global Growth Opportunities Fund, the Global Smaller Companies
Fund, and the Global Technology Fund Series of Seligman Henderson Global Fund
Series, Inc. as of October 31, 1997, the related statements of operations for
the year then ended and of changes in net assets (1) for the year then ended,
(2) for the year ended October 31, 1996 for the International Fund, the Global
Growth Opportunities Fund, the Global Smaller Companies Fund, and the Global
Technology Fund, and (3) for the period May 28, 1996 (commencement of
operations) to October 31, 1996, for the Emerging Markets Growth Fund, 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 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 at October
31, 1997, 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, such financial statements and financial highlights present
fairly, in all material respects, the financial position of each Series of
Seligman Henderson Global Fund Series, Inc. as of October 31, 1997, the results
of their operations, the changes in their net assets, and the financial
highlights for the respective stated periods in conformity with generally
accepted accounting principles.

GLOSSARY OF FINANCIAL TERMS

CAPITAL GAIN DISTRIBUTION -- A payment to mutual fund shareholders of profits
realized on the sale of securities in the fund's portfolio. For tax purposes,
these profits may be considered short-, mid-, or long-term capital gains and may
be taxed at different rates.

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 LOAD (CDSL) -- Depending on the class of shares owned,
a fee charged by a mutual fund when shares are sold back to the fund (the CDSL
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.

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 (OP) -- 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, officers and directors, how shares are bought and
redeemed, fund fees and other charges, and the fund's financial statements.

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 -- Document that contains updated or more
detailed information about a mutual fund and 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.
