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 135 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 into the new millennium.

TO THE SHAREHOLDERS

The past fiscal year witnessed a significant turnaround for the global economy
and stock markets. In the wake of the global financial crisis in 1998, major
central banks around the world lowered interest rates and provided liquidity. In
response, the world economy recovered significantly and stock markets rallied
strongly. In particular, Asian markets surged from very depressed levels.

The 12-month period was thus positive for global investors, including investors
in Seligman Henderson Global Fund Series, which boasts double-digit 12-month
returns for each Fund in the Series. While investor sentiment is vastly improved
from one year ago, the outstanding stock market returns and robust economic
growth have triggered concerns regarding inflation. The US Federal Reserve
Board, in particular, has been vigilant and raised the federal funds rate three
times during calendar year 1999, which completely reversed all of 1998's rate
cuts.

Looking ahead, we believe that the environment for global stock markets will
continue to be positive, although it will be difficult for stock markets to
match some of the spectacular gains they posted this past fiscal year. The
possibility of rising interest rates may dampen returns somewhat, but we believe
that strong economic growth around the world will continue to create a
supportive environment for global stock markets.

As the millennium approaches, we have become concerned that the media's focus on
the Year 2000 (Y2K) computer issue, and the fears that this attention may spark,
will cause some investors to take actions that are not in their best long-term
interests. In our view, the primary danger to investors is losing sight of their
long-term financial goals and altering their portfolios and asset allocations in
an attempt to respond to the confusion surrounding this issue.

In the US, governments and businesses have committed substantial resources to
this issue and, while there may be scattered inconveniences, we believe that the
US will enter the year 2000 relatively seamlessly, and that much of the rest of
the developed world is also well positioned to deal with the new millennium. We
are confident that the financial services industry (including the Funds'
custodians and foreign sub-custodians) will experience no major disruptions.

For the past several years, J. & W. Seligman & Co. Incorporated, your Funds'
manager, has been working to ensure that shareholders do not experience any
Y2K-related inconveniences. We are pleased to report that the early start has
paid off. During the spring of this year, Seligman participated in Y2K testing
conducted by the Securities Industry Association, a US trade group. These tests
were completed without any Y2K-related problems on the part of Seligman. Tests
with key service providers were also conducted, all of which were successfully
completed in a Y2K environment. The Funds' portfolio management teams have also
sought to minimize the impact on Fund portfolios from companies, including those
companies based outside the US, that we believe are not adequately prepared for
the year 2000.

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

During the fiscal year ended October 31, 1999, economic activity improved
markedly and global stock markets recovered sharply. At calendar year end 1998,
investors were concerned about the prospects for the world economy; however,
throughout calendar year 1999, the economic outlook steadily improved for all
regions. In particular, two of the largest economies, Japan and Germany, which
had been laggards, improved considerably. The strong global recovery has
generally improved investor sentiment, but has also raised concerns that overly
robust growth could trigger inflation, and global interest rates have moved
higher in response.

UNITED STATES

In October 1998, investors were concerned that the US economy might have been
pulled into a recession as a result of the world economic crisis. However, rate
easings by the US Federal Reserve Board and other central banks enabled the
global economy to recover. In the US, growth continued to be so strong that the
Fed became concerned that the pace of expansion might pose an inflationary
threat. The Fed thus reversed all its 1998 rate cuts during calendar year 1999.
The US stock market hit new highs during the fiscal year and posted strong
returns, although the gains were not as extraordinary as those posted by many of
the foreign markets that were very depressed last year.

UNITED KINGDOM

Overall, the stock market in the UK delivered strong performance, but there was
significant divergence between sectors. Service and domestic-related areas
performed well, while exports continued to suffer as a result of the strength of
the British pound sterling.

CONTINENTAL EUROPE

In the early part of the fiscal year, most major economies in Continental Europe
were struggling to grow at a reasonable pace. This was evidenced by the weakness
of the euro against the dollar since the formation of European Monetary Union at
the beginning of calendar year 1999. However, easier monetary policy, combined
with a weak currency and a resurgence in Asian economic activity, boosted the
economy overall, and manufacturing in particular. This improved the outlook for
Germany -- Europe's largest economy -- where manufacturing continues to play a
crucial role.

European stock markets generally followed the trends of the US markets, but a
weak currency caused US-dollar returns to be lower. Corporate profits continued
to grow at a reasonable pace, and a significant amount of merger and acquisition
activity has helped to maintain investor interest in the markets.

JAPAN

The Japanese government's continued huge fiscal expenditures finally began to
pay off and economic growth in the first half of the calendar year was ahead of
most expectations. Improvement in the private sector contributed to a stronger
yen, which has been slightly negative for economic growth, but positive for
foreign investors. The improving economy, in addition to corporate
restructuring, allowed the Japanese stock market to deliver the best performance
of the major markets during the one-year period under review.

PACIFIC REGION

Many Pacific region economies, although not all, have recovered markedly during
calendar year 1999. The economies of Korea and Singapore were the most improved
and their markets delivered the best performances in the region. By contrast,
Hong Kong lagged somewhat, since it did not have a weak currency to assist its
exports. More recently, stock markets have leveled off somewhat following the
large gains of the first half of the Fund's fiscal year.

EMERGING MARKETS

Despite the problems in Brazil in the early part of the period, Latin America
performed well as a result of the improving outlook for world economic growth.
The Russian economy also stabilized, benefiting emerging markets in Europe.

SUMMARY

This past fiscal year has been one of improving economic conditions worldwide.
While this has led to strong stock market returns, particularly in some of the
markets which were hardest hit by the economic crisis of 1998, it has also
produced inflationary concerns. Although there have been no clear signs of
inflation, central banks in the US, UK, and countries within European Monetary
Union have recently raised short-term rates in response. Long-term bond yields
also reacted negatively to rising world demand and rose significantly. Rising
rates modestly dampened returns for most Western stock markets. The most
spectacular gains have been in Asia, where we believe there is still ample room
for recovery before inflation becomes a threat.

INVESTMENT REPORT
Seligman Henderson International Fund


PERFORMANCE REVIEW

For the fiscal year ended October 31, 1999, Seligman Henderson International
Fund posted a total return of 20.96%, based on the net asset value of Class A
shares, compared to 25.42% for the Lipper International Funds Average and 23.37%
for the Morgan Stanley Capital International Europe, Australasia, Far East (MSCI
EAFE) Index.

The fiscal year was characterized by wide variations in regional stock market
performance. European markets, in general, rose modestly. Although the economic
background was positive, higher short- and long-term interest rates placed a
drag on market performance. In contrast, Asian stock markets -- both in Japan
and elsewhere -- rose strongly, as investors became confident that the economic
recovery in the region would be sustained.

PORTFOLIO STRATEGY

UNITED KINGDOM

The UK stock market generally tracked the ups and downs of the US market, with
significant volatility. As it became clear that the global economy was
recovering, domestic and economically sensitive stocks began to perform well.
However, there was an abrupt change in July when the Bank of England raised
interest rates, causing cyclical stocks to sell off sharply. Throughout the
period, UK technology and telecommunications stocks performed well.

The Fund's weighting in the UK remained generally stable over the period. The
Fund was overweighted in economically sensitive stocks, and this contributed to
positive performance for most of the year. Following the interest rate hike in
the UK, however, we adopted a more neutral position on these stocks.

CONTINENTAL EUROPE

In local currency terms, European stock markets performed reasonably well.
However, the weakness of the euro depressed US dollar returns, which were
generally flat for the fiscal year. Also, as in the UK, there were significant
performance differences between sectors. Economically sensitive stocks generally
performed well, while defensive stocks underperformed. Telecommunication and
technology stocks were strong performers throughout the year. A positive factor
for the market has been the large amount of merger and acquisition activity,
particularly in the financial and manufacturing sectors, which we believe is
likely to continue throughout the next fiscal year.

The Fund's overweighting in Continental Europe throughout the year dampened Fund
performance relative to its benchmarks. However, our decision to reduce the
Fund's exposure to defensive stocks early in the year was beneficial. Now that
the economic recovery has broadened throughout Europe and strong corporate
profit growth is expected to con-tinue, we will likely maintain the Fund's
overweighted position in Continental Europe.

JAPAN

The Japanese stock market, boosted by a very strong rise in the Japanese yen
versus the US dollar, was the

INVESTMENT REPORT

strongest-performing major stock market this year. The big turnaround came
toward the end of the first quarter at the first signs of economic recovery. In
particular, the stock market rally has been driven by large inflows of money
from foreign investors. The strong yen, however, dampened profits in the export
sector. Investors have focused on what could be described as "new Japan" stocks,
mainly in the service and technology sectors.

The Fund initially had a low weighting in Japan. We did, however, increase this
weighting significantly during the fiscal year, particularly in early March.
However, the Fund remains underweighted versus the MSCI EAFE Index. We will
likely further increase the Fund's weighting in Japan during the coming fiscal
year, but we will be cautious because we are slightly concerned about the yen at
current levels and think that it may now begin to weaken. We believe that this
may in fact be required to keep the Japanese economy moving forward.

PACIFIC REGION

In the Pacific, stock market performance was mixed. The strongest economic and
market recoveries were in Korea and Singapore. In contrast, continued political
turmoil in Indonesia negatively affected stock market performance there. Hong
Kong and Australia both posted moderate gains, both in terms of economic growth
and stock market performance. Overall, improving economic growth on a global
basis should be positive for the Pacific region.

The Fund remained underweighted in the region, which was clearly a negative,
given the strength of the regional recovery. However, over the last few months,
Asian stock markets have slightly underperformed those elsewhere, and this
weakness may provide the Fund with an opportunity to increase the portfolio's
exposure to the region during the coming fiscal year.

EMERGING MARKETS

Improving global growth is generally positive for emerging markets, and they
thus performed well during the fiscal year. The fears of last year have
subsided, and foreign investors have gradually started to return to these
markets. The Fund reduced its exposure to emerging markets during the period,
but the portfolio's overweighting in Greece helped overall performance.


OUTLOOK

The global economic outlook remains positive, with steady growth and low
inflation likely to continue. While interest rates are unlikely to rise
sufficiently to be a serious negative, central banks are now more wary of
creeping inflation, and interest rates may rise slightly further from current
levels, which could somewhat dampen sentiment and stock market performance. We
expect earnings growth outside the US to continue, and international stock
markets to perform better following their long period of underperformance
against the US stock market.

   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 per share 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 for
     Class B shares are calculated with and without the effect of the maximum 5%
     contingent deferred sales charge ("CDSC"), 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 C shares are calculated with and
     without the effect of the initial 1% maximum sales charge and the 1% CDSC,
     charged on redemptions made within 18 months of the date of purchase.
     Returns for Class D shares are calculated with and without the effect of
     the 1% CDSC, charged on redemptions made within one year of the date of
     purchase.
 *** The Lipper International Funds Average and the Morgan Stanley Capital
     International 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 CDSC is 5% for periods of one year or less, and 3% since inception.

PERFORMANCE AND PORTFOLIO OVERVIEW
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, and assumes that all distributions within the period are
invested in additional shares, since the commencement of investment operations
on April 7, 1992, through October 31, 1999, to a $10,000 hypothetical investment
made in the Lipper International Funds Average and the Morgan Stanley Capital
International Europe, Australasia, Far East Index (MSCI EAFE Index) for the same
period. It is important to keep in mind that indices and averages exclude the
effect of fees and/or 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, Class C, and Class 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

For the fiscal year ended October 31, 1999, Seligman Henderson Emerging Markets
Growth Fund posted a total return of 29.15%, based on the net asset value of
Class A shares, compared to 35.90% for the Lipper Emerging Markets Funds Average
and 44.63% for the Morgan Stanley Capital International Emerging Markets Free
(MSCI EMF) Index.

During the first half of the Fund's fiscal year, emerging markets rose strongly
on a relief rally following the extreme market weakness experienced during the
Russian currency devaluation crisis of August/September 1998. Korea, Indonesia,
Malaysia, and Russia benefited the most, and their markets doubled during that
six-month period. During the second half of the Fund's fiscal year, however,
market performance was more mixed. Latin America, in particular, suffered over
US interest rate worries.

The Fund's underperformance compared to its benchmarks during the fiscal year
was largely due to two factors. First, at the beginning of the fiscal year, we
were concerned about the financial condition of corporations in Asia and were
thus cautious about investing in the region; these markets subsequently rallied
strongly. Second, we overweighted the Fund in emerging Europe during the first
fiscal quarter because we expected strong economic recoveries in the region.
However, these economies did not recover until the third calendar quarter of
1999 and, in the interim, the Kosovo military conflict damaged investor
confidence in these markets.

PORTFOLIO STRATEGY

During the fiscal year, we made a number of major asset allocation changes to
the Fund's portfolio. We began to overweight the Pacific region, which began to
experience a significant economic recovery during the period. We reduced the
Fund's holdings in Central Europe during the Kosovo crisis and then again at the
end of the fiscal year, when we reduced the portfolio's exposure to Greece,
which we perceived to be overvalued. We increased the Fund's exposure to India
during the second half of the fiscal year when it became evident that the
economy was experiencing a major recovery. Also in the second half of the Fund's
fiscal year, we increased the portfolio's exposure to South Africa when a
revival in commodities became evident.

NORTH PACIFIC REGION

In the North Pacific, the South Korean market rose 161.8%, substantially
outperforming other regional markets. Improving market confidence based on
economic recovery, inflows of liquidity from foreign investors, and a balance of
payments surplus were the principal causes behind the rally. The Taiwanese
market, which fell less than other regional markets during the 1997/1998 crisis,
also rebounded, but by a more subdued 27.9%. For most of the fiscal year, the
Chinese stock market was affected by concerns over deflation and poor growth
prospects, and rose a relatively modest 14.1%.

Early in the fiscal year, we increased the Fund's exposure to both the Korean
and Taiwanese markets. In Taiwan, we moved the Fund's focus away from closed-end
funds and invested in domestic technology issues. In China, we continued to
pursue infrastructure stocks.

- --------------------------------------------------------------------------------
 FUND OBJECTIVE
 Seligman Henderson Emerging Markets Growth Fund, which commenced operations on
 May 28, 1996, seeks long-term capital appreciation by investing primarily in
 equity securities of emerging markets around the world.

INVESTMENT REPORT
Seligman Henderson Emerging Markets Growth Fund


SOUTH PACIFIC REGION

Performances in the South Pacific markets of Indonesia, Thailand, and the
Philippines varied greatly. Despite political uncertainty, the Indonesian market
posted the best performance, rising 164.3%, due to a strong rally in the rupiah
and improving confidence in the economy. In Thailand and the Philippines, the
markets were more subdued as a result of weak economic improvement, and rose
27.6% and 8.3%, respectively.

The Fund maintained limited exposure to these markets during the period. We
reduced the Fund's exposure to Indonesia ahead of the millennium because we
believe that this country's computers may not be as prepared as we would like
for the year 2000.

During the fiscal year, we avoided the Malaysian stock market. The government
only recently, in October 1999, clarified the currency controls it had imposed
in September 1998, and we felt that this market thus posed too many
uncertainties during this time period.

Over the fiscal year as a whole, Latin American markets posted positive results,
but gains were less spectacular than those of other regions. The Mexican market
advanced 36.6% due to an acceleration in economic growth and a benign interest
rate environment. The Chilean and Argentinean markets advanced 19.6% and 16.2%,
respectively. Despite the floating of the Brazilian currency in January and its
subsequent devaluation, the Brazilian market gained 3.2%.

During the period under review, we repositioned the Fund's portfolio in Mexico
from defensive stocks (with an emphasis on bottlers) to cyclical stocks. In
Brazil, we increased the portfolio's weighting in export-oriented stocks, after
the Brazilian currency devaluation.

EMERGING EUROPE

Performance in emerging European markets varied widely, with Russia, Greece, and
Turkey delivering the strongest performances. The Russian market rebounded
sharply from the August 1998 crisis and rose 103.3%. The Greek market rose 87.5%
as a result of the planned entry of the drachma into European Monetary Union,
which is expected to produce sharply lower interest rates. The Turkish market
also posted a strong performance of 78.9% based on expectations that inflation
will be reduced and interest rates will decline.

In contrast, market performances in Central Europe were relatively lackluster as
a result of poor economic growth and high levels of uncertainty during the
Kosovo crisis. The Polish market rose 6.6%, the Hungarian market rose 10.2%, and
the Czech Republic market rose 11.4%.

We maintained a significant weighting in Greece throughout the year, and the
Fund's Greek-bank holdings showed strong appreciation during the period. We also
re-established some of the Fund's positions in Russia during the period.

OTHER MARKETS

An acceleration of the Indian economy positively affected the Indian stock
market, which rose 61.5% during the period. By contrast, the South African
market rose just 12.3% due to high domestic interest rates and a fragile
currency.

During the period, we increased the Fund's exposure to the Indian stock market
and increased holdings in precious and base metals in South Africa.


OUTLOOK

The outlook for emerging markets for the coming fiscal year is encouraging, with
global economic growth accelerating and commodity prices likely to rally
further. Despite the recent rally, the Morgan Stanley Capital International
Emerging Markets Free Index is still more than 25% below its peak, which was
reached on September 1994, and we believe there is still great potential for
appreciation. However, rising US interest rates may cause some short-term
volatility.

PERFORMANCE AND PORTFOLIO OVERVIEW
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 3% contingent deferred sales
charge ("CDSC") for Class B shares, and without the 1% CDSC for Class D shares,
and assumes that all distributions within the period are invested in additional
shares, since the commencement of operations on May 28, 1996, through October
31, 1999, 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 indices and averages exclude the effect of fees and/or sales
charges.

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

     As shown on page 14, the performance of Class C shares will be greater than
or less than the performance shown for Class A, Class B 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 Growth Opportunities Fund


PERFORMANCE REVIEW

For the fiscal year ended October 31, 1999, Seligman Henderson Global Growth
Opportunities Fund posted a total return of 33.68%, based on the net asset value
of Class A shares, outpacing both the 26.28% total return of the Lipper Global
Funds Average and the 25.33% total return of the Morgan Stanley Capital
International World Index.

As markets around the world recovered over the past fiscal year, the Fund's
relative performance was influenced positively by three major factors. First,
the Fund was overweighted in the technology and telecommunications sub-themes,
which contributed significantly to the Fund's performance, since these sectors
outperformed the broader markets by a wide margin. The continually increasing
use of mobile communication devices, the Internet, and data transfer drove
demand for computers, software, and connectivity steadily higher during the
one-year period. Second, the Fund's emphasis on Japanese emerging growth
companies was timely, as this area of the market more than doubled in value
during the year. Third, the Fund's limited exposure to health care was
beneficial since the sector, which was plagued by investor concerns regarding
slower growth rates in the future, lagged considerably behind the broader market
averages.

PORTFOLIO STRATEGY

The Fund remained broadly invested in three major growth themes : Quality of
Life (29%), Productivity (42%), and Consumption (20%). During the year, we
significantly increased the Fund's exposure to the Productivity theme, which
includes information technology and telecommunication services, and reduced
exposure to the Consumption and Quality of Life themes.

QUALITY OF LIFE

During the first six months of the fiscal year, we substantially reduced the
Fund's investment in the health care sub-theme. While pharmaceutical stocks
continue to have exciting long-term growth prospects, supported by patents and
proprietary research, we concluded that, for many holdings, optimism for the
future was fully reflected in current prices.

PRODUCTIVITY

We continued to add substantially to the telecommunications sub-theme. The
increase in voice and data traffic over growing numbers of networks shows no
sign of abating. In fact, the demand for ever-greater bandwidth is likely to
accelerate. Telecommunications has now over

- --------------------------------------------------------------------------------
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.

taken both technology and consumer staples as the biggest sub-theme, with
approximately 16% of the Fund's total net assets invested in this area.

Around the world, we added several new telephone stocks. The most significant of
these include the dominant fixed-line and mobile network providers. In total,
the Fund has sixteen telecommunications-related investments.

Within the technology sub-theme, we added new investments in Asia. Following the
sharp economic contraction in the region, technology-related stocks there
offered what we perceived to be rare growth opportunities. In Japan, we added
companies involved in computer-system integration.

CONSUMPTION

During the first half of the fiscal year, rising consumer confidence in
Continental Europe, which was due to falling unemployment and record low
interest rates, led us to increase exposure to consumer-related stocks in this
region. However, as increasing competition put pressure on profit margins, we
sold some retailers. Throughout the world, traditional retailing has been
threatened by new competition, including Internet retailing.

OUTLOOK

The news about global economic activity continues to be surprisingly positive.
As a result, interest rates are likely to move somewhat higher, first in the US
and Europe, and eventually in Asia. However, we believe that much of this
increase has already been anticipated by the markets. As long as inflationary
pressures remain relatively muted, we believe that investors will not be overly
concerned about higher interest rates. We expect that, as central banks around
the world tighten their monetary policies in pre-emptive moves against
inflation, long-term bond yields in most markets will begin to decline. Such a
scenario would be supportive for growth stocks.

Among the themes emphasized by the Fund, we are most encouraged by the outlook
for the technology and telecommunications sub-themes. Despite currently high
valuations, we expect that accelerating demand and corporate activity will
create exciting growth opportunities in these sectors.

In an environment of low inflation and intense competition, real growth will
continue to be scarce. The experience of recent years has also shown that
investors around the world are eager to invest in businesses that promise high
profit growth, and we believe that this situation will continue. During the
coming fiscal year, we will continue to apply our thematic approach when looking
for companies with prospects for superior growth.

    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 per share 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 B shares are calculated with and
      without the effect of the maximum 5% contingent deferred sales charge
      ("CDSC"), 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 C shares are calculated with and without the effect of the initial
      1% maximum sales charge and the 1% CDSC, charged on redemptions made
      within 18 months of the date of purchase. Returns for Class D shares are
      calculated with and without the effect of the 1% CDSC, charged on
      redemptions made within one year of the date of purchase.
  *** The Lipper Global Funds Average and the Morgan Stanley Capital
      International (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 CDSC is 5% for periods of one year or less, and 3% since inception.

PERFORMANCE AND PORTFOLIO OVERVIEW
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 charge ("CDSC") for Class D shares, and assumes that all distributions
within the period are invested in additional shares, since the commencement of
investment operations on November 1, 1995, through October 31, 1999, to a
$10,000 hypothetical investment made in the Lipper Global Funds Average and the
Morgan Stanley Capital International World Index (MSCIWorld Index) for the same
period. It is important to keep in mind that indices and averages exclude the
effect of fees and/or 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 performances of Class B and Class C 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

For the fiscal year ended October 31, 1999, Seligman Henderson Global Smaller
Companies Fund posted a total return of 11.55%, based on the net asset value of
Class A shares, compared to 26.86% for the Lipper Global Small Cap Funds Average
and 17.46% for the Salomon Smith Barney Extended Market Index World.

The performances of smaller companies around the world were mixed during the
fiscal year. Continually improving world economic growth should have provided a
very positive environment for global smaller companies. However, these companies
generally -- with the exception of some very specific sectors -- suffered from a
lack of pricing power, resulting in a difficult operating environment for many
of them. Recently, in some markets, small-capitalization stock performance has
been improving.

- --------------------------------------------------------------------------------
FUND OBJECTIVE

Seligman Henderson Global Smaller Companies Fund, which commenced investment
operations on September 9, 1992, seeks long-term capital appreciation by
investing in smaller-company stocks in the US and around the world.

PORTFOLIO STRATEGY

UNITED STATES

In the US, smaller companies trailed significantly behind their
large-capitalization counterparts. The Fund's US portfolio also suffered during
the period from its exposure to some health care stocks that delivered poor
performances during the fiscal year. However, the Fund benefited from being
underweighted, versus the Salomon Smith Barney Extended Market Index World, in
the US small-capitalization market.

UNITED KINGDOM

Of all the major markets, UK smaller companies delivered the strongest
performances relative to larger companies, particularly during the first six
months of the calendar year. More recently, however, smaller companies in the UK
have slightly underperformed the broader market as interest rates have begun to
move higher.

During the fiscal year, the Fund remained consistently overweighted in the UK,
with particular emphasis on service companies and technology. This has been a
benefit as several companies in these areas have performed very well. However,
we believe that these companies are nearly fully valued, and we anticipate
steadily decreasing our

INVESTMENT REPORT

weighting in the UK in favor of other international regions over the next few
months.


CONTINENTAL EUROPE

Smaller companies in Continental Europe generally remained out of favor through
most of the period. The focus of most of the merger and acquisition activity was
concentrated among large companies. As a result, smaller companies have not
performed particularly well, even where earnings growth has been very positive.

The portfolio's generally neutral to slightly overweighted position in
Continental Europe during the period had a negative impact on the Fund's
relative performance. Within the Fund's international portfolio, we have been
more optimistic regarding the prospects for other areas. However, valuations are
now quite low, and we are looking for an opportunity to increase our weighting,
since economic growth prospects are also improving.

JAPAN

While smaller companies participated in the Japanese stock market rally, they
generally lagged the returns of larger companies. However, certain companies and
sectors, where investors perceive good growth prospects, have performed well.
These have generally been "new Japan" stocks and fall largely within the service
and technology areas. Looking ahead, we believe that the improving economic
outlook will be supportive of smaller companies overall.

We began to significantly overweight Japan in the early part of the calendar
year, which was beneficial for performance. In particular, the Fund has good
exposure to companies that have the potential to grow rapidly, and some of these
have performed well during the year. However, valuations for high-growth
companies are now quite high, and we thus do not anticipate increasing the
Fund's Japanese weighting any further.

PACIFIC REGION

Smaller companies generally performed in line with larger companies throughout
the region, and thus rose during the course of the fiscal year. As elsewhere in
the world, however, the market has become sharply polarized. Companies showing
good bottom-line growth have performed well, while all others have stagnated.

During the course of the fiscal year, we began to significantly overweight the
Fund's position in the Pacific region. We have focused on technology and
service-related areas, and the companies in the Fund's portfolio have generally
performed well. The year 2000 seems likely to be positive for small companies in
the Pacific. We anticipate remaining overweighted in the region and may even
increase the Fund's exposure further.

OUTLOOK

Although smaller companies have underperformed the broader markets overall, the
best smaller companies have generally been rewarded. The global economic
background is supportive, but investors continue to demand high liquidity, and
this does not favor smaller companies. Valuations as a whole are attractive, but
in some specific growth areas, such as technology, we believe that they are now
quite high.

The coming fiscal year is likely to be challenging. The ongoing focus on
liquidity has favored larger companies, but we believe that this could turn
around sharply over the next 12 months. Overall, we believe the outlook for
smaller companies around the world is positive.

   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 per share 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 B shares are calculated with and
      without the effect of the maximum 5% contingent deferred sales charge
      ("CDSC"), 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 C shares are calculated with and without the effect of the initial
      1% maximum sales charge and the 1% CDSC, charged on redemptions made
      within 18 months of the date of purchase. Returns for Class D shares are
      calculated with and without the effect of the 1% CDSC, charged on
      redemptions made within one year of the date of purchase.

   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, Class C, and Class 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 fiscal year ended October 31, 1999, Seligman Henderson Global Technology
Fund posted a total return of 89.40%, based on the net asset value of Class A
shares, compared to 26.18% for the Lipper Global Funds Average, 109.20% for the
Lipper Science & Technology Funds Average, and 25.33% for the Morgan Stanley
Capital International World Index.

The global technology sector delivered outstanding performance during the fiscal
year ended October 31, 1999. In most market sectors around the world, the
disinflationary environment that has been prevalent around the globe has had a
negative effect on corporate earnings. The technology industry, however, has
continued to deliver strong earnings growth, and technology stock prices have
thus received a higher and higher scarcity premium.

- --------------------------------------------------------------------------------
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.

PORTFOLIO STRATEGY

The Fund's "growth-at-a-reasonable-price" philosophy proved to be a prudent
approach during the period. The Fund has avoided investing in stocks with
price-to-earning ratios that we believe are too high, and has therefore largely
avoided the highly volatile Internet sector. While this strategy hurt the Fund's
relative performance during the first quarter of 1999, when the sector posted
spectacular gains, the Fund was also able to outperform its peers when these
stocks experienced a sharp pullback in May. The Fund's low exposure to this
sector has also allowed the Fund to be less volatile than many of its peers.

INVESTMENT REPORT
Seligman Henderson Global Technology Fund


After gaining some liquidity during the summer, we entered the latter part of
the year fully invested. Asset allocation between different geographical areas
has remained relatively unchanged, but we markedly increased the Fund's exposure
to cyclical technology companies. The semiconductor industry is just one year
into what we believe will be a two- to three-year upswing, and we anticipate
continuing strong performance over the next 12 months.


UNITED STATES

Despite a dramatic selloff of Internet stocks over the summer, the US technology
sector, after an initial setback, performed well, with the Pacific Stock
Exchange Technology Index rising nearly 30% during the second half of the fiscal
year alone. Communications stocks continued to rise strongly as a result of
surging demand for infrastructure, and frenetic merger/acquisition activity
among carriers. Semiconductor companies performed well as orders surged, causing
their stock prices to rise dramatically. Although Y2K may cause some disruption
in demand, most investors seem willing to look past what we believe should be
only a brief hiatus in this momentum.

EUROPE

In Europe, initial nervousness about Y2K seems to have subsided. The Morgan
Stanley Eurotech Index rose 60% during the fiscal year, led by the strength of
wireless stocks and enthusiasm regarding the recovery prospects for some of the
more cyclical technology companies. There is increasing evidence that demand for
technology products and services in Europe will accelerate as adoption rates
begin to move toward the more advanced levels prevalent in the US.

ASIA

Asia also lags far behind the US in terms of demand for technology but, with
recovery solidly underway, this appears to be changing rapidly. During the
fiscal year, Japanese and Taiwanese semiconductor shares enjoyed a particularly
strong rally.

OUTLOOK

Valuations for technology stocks have risen to levels not seen in many years.
However, the sector's earnings momentum remains strong and, relative to the
broader markets, has seldom been better. While we believe that investor
enthusiasm for these stocks calls for caution, we remain optimistic about the
outlook for global technology.

   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 per share 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 B shares are calculated with and
      without the effect of the maximum 5% contingent deferred sales charge
      ("CDSC"), 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 C shares are calculated with and without the effect of the initial
      1% maximum sales charge and the 1% CDSC, charged on redemptions made
      within 18 months of the date of purchase. Returns for Class D shares are
      calculated with and without the effect of the 1% CDSC, charged on
      redemptions made within one year of the date of purchase.
  *** The Lipper Global Funds Average, the Lipper Science & Technology Funds
      Average, and the Morgan Stanley Capital International (MSCI) World Index
      are unmanaged benchmarks that assume reinvestment of dividends. The Lipper
      Global Funds Average and the Lipper Science & Technology Funds Average
      exclude the effect of sales charges and the MSCIWorld Index excludes the
      effect of fees and sales charges. The monthly performances of the Lipper
      Global Funds Average and the Lipper Science &Technology Funds Average are
      used in the Performance and Portfolio Overview. Investors cannot invest
      directly in an average or an index.

PERFORMANCE AND PORTFOLIO OVERVIEW
Seligman Henderson Global Technology Fund


     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
charge ("CDSC") for Class D shares, and assumes that all distributions are
invested in additional shares, since the commencement of operations on May 23,
1994, through October 31, 1999, to a $10,000 hypothetical investment made in the
Lipper Global Funds Average, the Lipper Science &Technology 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 indices and averages exclude
the effect of fees and/or 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 48, the performances of Class B and Class C 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.

NOTES TO FINANCIAL STATEMENTS

1. MULTIPLE CLASSES OF SHARES -- Seligman Henderson Global Fund Series, Inc.
(the "Series") consists of five separate Funds: Seligman Henderson International
Fund (the "International Fund"), Seligman Henderson Emerging Markets Growth Fund
(the "Emerging Markets Growth Fund"), Seligman Henderson Global Growth
Opportunities Fund (the "Global Growth Opportunities Fund"), Seligman Henderson
Global Smaller Companies Fund (the "Global Smaller Companies Fund"), and
Seligman Henderson Global Technology Fund (the "Global Technology Fund"). Each
Fund of the Series 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 Series 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 for
each Fund 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 Series:

a. SECURITY VALUATION -- Securities traded on an exchange 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 for which there is no last sales price, 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 Fund may temporarily hold funds in
   foreign currencies. The books and records of the Series 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 Series' 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 Series. 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
   Series' 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 Series 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 Series 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.


                                       59
<PAGE>

NOTES TO FINANCIAL STATEMENTS

c. FORWARD CURRENCY CONTRACTS -- The Series 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 or forward 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 Fund 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 Series' 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 -- Each Fund's income, expenses (other than
   class-specific expenses), and realized and unrealized gains or losses are
   allocated daily to each class of shares of that Fund based upon the relative
   value of the 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, 1999, 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 any Fund of the Series. On
   November 18, 1999, the International Fund, Global Growth Opportunities Fund,
   and Global Technology Fund declared distributions per share of $1,728,
   $1,171, and $2,446, respectively, from net realized long-term gains from
   investment transactions. The capital gains were paid on November 23, 1999, to
   shareholders of record on November 18, 1999.

3. PURCHASES AND SALES OF SECURITIES -- Purchases and sales of portfolio
securities, excluding short-term investments, for the year ended October 31,
1999, were as follows:

       FUND                     PURCHASES          SALES

purposes was as follows: International Fund $70,293,520; Emerging Markets Growth
Fund $52,665,054; Global Growth Opportunities Fund $154,558,723; Global Smaller

   Each Fund of the Series 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 Series pursuant to the Plan. For the year
ended October 31, 1999, 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 $103,943, $68,209,
$279,246, $678,107, and $1,543,038, respectively, or 0.24%, 0.25%, 0.25%, 0.25%,

distribution assistance of up to 0.75% on an annual basis of such average daily
net assets. Such fees are paid monthly by the Series 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 Series 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

5. COMMITTED LINE OF CREDIT -- The Series is a participant in a joint $750
million committed line of credit that is shared by substantially all funds in
the Seligman Group of Investment Companies. Each Fund's borrowings are limited
to 5% 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%. Each
Fund incurs a commitment fee of 0.08% 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 2000, but is renewable annually with
the consent of the participating banks.

   During the year ended October 31, 1999, the Global Smaller Companies Fund
periodically borrowed from the credit facility. The average outstanding daily
balance of the bank loans (based on the number of days the loans were
outstanding) was $11,145,000, with a weighted interest rate of 5.24%. The
maximum borrowing outstanding during the year was $17,400,000. The interest
expense incurred for the year was $19,461, which is included in miscellaneous
expenses in the Statements of Operations.

6. CAPITAL LOSS CARRYFORWARD -- At October 31, 1999, the Emerging Markets Growth
Fund had a net capital loss carryforward for federal income tax purposes of
$18,873,104, which is available for offset against future taxable net capital
gains, expiring in various amounts through 2006. Accordingly, no capital gain
distributions are expected to be paid to shareholders of this Fund until net
capital gains have been realized in excess of the available capital loss
carryforwards.

FINANCIAL HIGHLIGHTS

The tables below are intended to help you understand the financial performance
of each Class of each Fund for the past five years or from its inception if less
than five 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 during the period. "Total
return" shows the rate that you would have earned (or lost) on an investment in
each Class, assuming you reinvested all your dividend 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 HENDERSON GLOBAL FUND SERIES, INC.:

We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments, of Seligman Henderson Global Fund Series, Inc.,
(comprising, respectively, the International Fund, the Emerging Markets Growth
Fund, the Global Growth Opportunities Fund, the Global Smaller Companies Fund,
and the Global Technology Fund), as of October 31, 1999, the related statements
of operations for the year then ended and of changes in net assets for each of
the years in the two-year period then ended, and the financial highlights for
each of the periods presented. These financial statements and financial
highlights are the responsibility of the Series' 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, 1999, by correspondence with the Series' 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 referred to
above present fairly, in all material respects, the financial position of each
of the respective Funds constituting the Seligman Henderson Global Fund Series,
Inc. as of October 31, 1999, the results of their operations, the changes in
their net assets, and their 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 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 -- Adocument 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.
