TO OUR SHAREHOLDERS,

      Investors  hung  up on  global  telecommunications  stocks  in the  second
quarter  of  2000.  In  general,   telecommunications   companies  met  earnings
expectations,  industry  fundamentals  remained strong, and although  regulators
increased their scrutiny of proposed mergers in the telecommunications industry,
deals were  still  getting  done.  However,  concern  over high  valuations  and
investor  uneasiness sparked by the sharp technology stock correction inspired a
bout of profit taking in the telecommunications sector.

      Looking ahead, the long-term outlook for telecommunications stocks remains
quite  bright.  New  technology,  new products and services,  deregulation,  and
consolidation,  the four  forces  that have been  propelling  telecommunications
stocks,  are  still  in  place.  We  believe  that  after a brief  time on hold,
telecommunications stocks will regain momentum.


INVESTMENT PERFORMANCE

      For  the  second   quarter  ended  June  30,  2000,   The  Gabelli  Global

10.15%.  The Morgan  Stanley  Capital  International  World Free Index of global
equity markets and Salomon Smith Barney Global Telecommunications Index declined
3.81% and 20.90%, respectively, over the same period. Each index is an unmanaged

twelve-month  period.  The Morgan  Stanley  World Free Index and  Salomon  Smith
Barney  Global  Telecommunications  Index rose 12.37% and 19.80%,  respectively,
over the same twelve-month period.

      For the  five-year  period  ended June 30,  2000,  the Fund's total return

the  Morgan   Stanley   World  Free  Index  and  Salomon   Smith  Barney  Global
Telecommunications Index, respectively. Since inception on November 1, 1993

PAST  PERFORMANCE  IS NO GUARANTEE OF FUTURE  RESULTS.  Morningstar  proprietary
ratings reflect historical risk adjusted performance as of June 30, 2000 and are
subject to change every month.  Morningstar ratings are calculated from a Fund's
three,  five and  ten-year  average  annual  returns in excess of 90-day  T-Bill
returns with  appropriate  fee  adjustments and a risk factor that reflects fund
performance  below 90-day  T-Bill  returns.  The top 10% of the funds in a broad
asset class receive five stars,  the next 22.5% receive four stars, the next 35%
receive three stars, the next 22.5% receive two stars and the bottom 10% receive
one star.

COMMENTARY

TMT

      Last year the Fund excelled in what pundits called the "TMT"  (Technology,
Media,  and  Telecommunications)  stock  market.  This  quarter,  "tmt" has been
reduced to lowercase letters,  as all three groups declined.  Telecommunications
stocks  were  not  hit  nearly  as  hard  as  technology   stocks,  but  drifted
substantially lower than last quarter's marks. We believe industry  fundamentals
remain sound and that  earnings  will  continue to grow at an  attractive  pace.
However,  we  concede  that  after  several  years of  exceptional  performance,
telecommunications  stock prices had become  extended and some profit taking was
justified.

      We are not wringing our hands over this decline.  With momentum  investors
playing  an  increasingly  active  role  in  the  market,  stocks  in  spotlight
industries such as  telecommunications  will periodically  become overvalued and
vulnerable   to  a   correction.   This  hardly   diminishes   their   long-term
attractiveness.  As we have frequently stated, modern telecommunications systems
are critical for economic success on the world stage. Technology is creating new
ways to transmit  voice and data and a wealth of new products and services  that
businesses  and consumers  desire.  Regulatory  barriers  continue to come down.
Merger and  acquisition  activity  should  remain  strong as  telecommunications
companies seek to improve their competitive positions in the industry and extend
their franchises. In short, the long-term outlook could not be brighter.


                                        3
<PAGE>

      Competition in the various sectors of the telecommunications industry will
produce  winners and losers.  Our research  strives to identify those  companies
best positioned to prosper.  If we succeed, we believe the Fund will continue to
deliver attractive returns to shareholders.


THE SCORECARD

      In recent quarters,  we have had an exceptionally  high portfolio  batting
average in a very enthusiastic telecommunications stock market. This quarter, we
experienced a mid-season slump. We do not think we were swinging at bad pitches,
but that widespread  profit taking threw a sweeping curve at  telecommunications
investors.

      A few of the  Fund's  smaller  holdings  hit home runs,  such as  Furukawa
Electric,  Cable &  Wireless  Jamaica,  and  Harcourt  General,  which  hired an
investment backer to explore strategic  options,  including the possible sale of
the company.  Some of the larger holdings in the Fund hit for extra bases. Media
giant  Viacom  put  up  good  numbers,  our  largest  cable  television  holding
Cablevision  Systems posted a nice gain, and Regional Bell Operating Company SBC
Communications came through in the clutch.

      Our European, Asian, and Latin American telecommunications investments all
struck out and our wireless holdings never got the bat off their shoulders. Both
of these sectors had been knocking the cover off the ball in recent quarters and
were  particularly  vulnerable to profit taking.  Investors also booed AT&T, the
Babe Ruth of the telecommunications industry.

LET'S TALK STOCKS

      The  following  are stock  specifics  on  selected  holdings  of our Fund.
Favorable  earnings  prospects do not  necessarily  translate  into higher stock
prices,  but they do express a positive trend which we believe will develop over
time.  The share  prices of the  following  holdings  are stated in U.S.  dollar
equivalent terms as of June 30, 2000.

AT&T WIRELESS GROUP (AWE - $27.875 - NYSE),  owned by AT&T Corp.,  is the second
largest wireless  carrier in the U.S.,  serving over 10 million  customers.  The
company was spun-off as a tracking stock with AT&T maintaining majority control.
AWE  is  intended  to  track  the  performance  of  fixed  and  mobile  wireless
initiatives of AT&T.

CABLE & WIRELESS PLC (CWP - $50.0625 - NYSE) is a United Kingdom-based  provider
of global telecommunications  network services. Its key assets include ownership
in leading voice,  data & IP networks in the U.K. and U.S.;  numerous  stakes in
undersea telecom network routes;  and a strong regional presence in Asia/Pacific
& Europe and the  Caribbean/Latin  America.  Sale of Cable & Wireless HKT plc to
Pacific Century Cyberworks is still pending and is expected to close shortly. As
a result of this transaction, CWP will hold a meaningful position in PCCW.

CENTURYTEL INC. (CTL - $28.75 - NYSE), based in Monroe, Louisiana, is the eighth
largest local telephone  company in the U.S., with over 1.2 million access lines
in the South and Midwest.  CenturyTel also has over 700,000 cellular  customers.
Through  acquisitions,  CTL has created clusters of rural telephone and cellular
companies  within commuting  distance of metropolitan  areas in states including
Wisconsin,

                                        4
<PAGE>

Michigan,  Ohio,  Louisiana and Arkansas.  With the $2.2 billion  acquisition of
Portland-based Pacific Telecom, CTL has added seven states, ten cellular markets
and 640,000  access lines to its customer  base.  The acquired  operations  have
nearly doubled  Century's  revenues.  The company recently  announced that it is
acquiring  about 460,000 access lines in 3 states for $1.5 billion.  The company
continues to build value through other ventures, primarily its long distance and
competitive local exchange carrier operations.

GTE CORP. (GTE - $62.25 - NYSE),  following its merger with Bell Atlantic (BEL -
$50.8125  - NYSE),  has been  renamed  Verizon  Communications  (VZ - NYSE).  VZ
becomes  the largest  domestic  provider  of  wireline  communications,  with 95
million access line  equivalents.  Verizon is also the largest domestic wireless
carrier,  with about 25 million  subscribers,  and is one of the world's largest
and most successful  wireless  companies,  with domestic operations in 24 states
and international  investments in Latin America,  Europe and the Pacific Rim. In
early April,  BEL, GTE and Vodafone  AirTouch  (VOD - $41.4375 - NYSE)  finished
combining  their U.S.  wireless  operations  into a joint venture called Verizon
Wireless,  which will reach more than 90% of the U.S.  population.  VZ is also a
global leader in publishing directories and in providing Internet-based shopping
guides,  website creation and hosting,  and other electronic  commerce services.
The company has a mix of mature and start-up communications businesses in Europe
and the Pacific Rim, including a 24.9% stake in Telecom Corp. of New Zealand and
an 18.5% stake in Cable & Wireless Communications.

LIBERTY MEDIA GROUP (LMG'A - $24.25 - NYSE), owned by AT&T Corp. (T - $31.6245 -

interests  in  international   video  distribution   businesses,   international
telephony and domestic wireless,  plant and equipment  manufacturers,  and other
businesses related to broadband services.  Liberty Media Group Class A and Class
B common stock are tracking stocks of AT&T.

NORTEL  NETWORKS CORP. (NT - $68.25 - NYSE),  formerly  Northern  Telecom,  is a
leading global  supplier of data and telephony  network  solutions and services.
Its business consists of the design, development,  manufacture, marketing, sale,
financing,  installation,  servicing and support of data and telephony  networks
for carrier  and  enterprise  customers.  Customers  include  public and private
institutions;   local,  long-distance,   personal  communications  services  and
cellular mobile communications companies;  cable television companies;  Internet
service  providers;  and  utilities.  NT has a  presence  in over 150  countries
worldwide.

SBC  COMMUNICATIONS  INC. (SBC - $43.25 - NYSE) is the second  largest  regional
Bell  operating  company in the U.S.,  with over 60 million  domestic  and seven
million  proportionate  international  access  lines.  SBC also serves over 12.2
million  domestic and over four  million  proportionate  international  wireless
customers.  SBC has a  strong  presence  in  Europe  through  its  ownership  of
TeleDanmark (TLD - $34.00 - NYSE), Belgacom, Cegetel and other companies as well
as in Canada through ownership of Bell Canada (BCICF - $28.9375 - NASDAQ) and in
Mexico  through  Telmex  (TMX - $57.125 - NYSE).  In April,  SBC  announced  the
formation  of a joint  venture  with  BellSouth  (BLS -  $42.625  -  NYSE).  The
companies will combine their domestic  wireless  operations,  forming the second
largest wireless carrier in the U.S. behind Verizon Wireless (VZ - NYSE).

TELECOM ITALIA MOBILE SPA (TIM.MI - $10.24 - MILAN STOCK  EXCHANGE),  formerly a
subsidiary  of Telecom  Italia (the  provider  of wired local and long  distance
telephone service in Italy),  was spun-off in July 1998 and began trading on the
Milan Stock  Exchange as an  independent  company.  Telecom Italia Mobile is the
leading  cellular  provider  in Italy and  Europe,  with over 19 million  Global
Systems  for  Mobile   Communications   ("GSM")  subscribers.   The  competitive
environment in which Telecom Italia Mobile operates remains favorable, with only
two competitors, Omnitel and Wind.

TELEPHONE  &  DATA  SYSTEMS  INC.  (TDS  -  $100.25  -  AMEX)  is a  diversified
telecommunications  service company with cellular telephone, local telephone and
personal  communications  services  ("PCS")  operations.  TDS serves 3.7 million
customers  in 35  states.  TDS  conducts  the  vast  majority  of  its  cellular
operations  through its 81% owned United States  Cellular Corp.  (USM - $63.00 -
AMEX) and  conducts  its  telephone  operations  through  its  wholly-owned  TDS
Telecommunications  Corp.  ("TDS  Telecom")  subsidiary,  a  full-service  local
exchange  carrier.  Having  completed a merger of its 82%-owned  PCS  subsidiary
Aerial  Communications with VoiceStream  Wireless (VSTR - $116.2969 - NYSE), TDS
now owns 35.6 million shares of VSTR valued at over $5.0 billion.

VOICESTREAM  WIRELESS CORP. (VSTR - $116.2969 - NASDAQ) is one of the three U.S.
independent  wireless service  providers with licenses covering over 200 million
POPS (Points of Presence).  VSTR was spun-off of Western Wireless about fourteen
months ago and is the only national carrier utilizing GSM technology, a standard
which dominates in Europe.  VSTR's high growth rates and experienced  management
team,  as  well  as its  national  licenses,  make  the  company  an  attractive
acquisition target for major global telecommunications  companies, many of which
lack a U.S. presence.

IN CONCLUSION

      In recent years, we have benefited from a vibrant telecommunications stock
market.  We believe that solid earnings,  sound  fundamentals,  and the powerful
secular growth trends in the industry justified this advance.  This quarter,  we
experienced  some static on the line in the form of  widespread  profit  taking.
Going forward,  there will be other interruptions to contend with in the rapidly
changing  telecommunications  industry.  However, we believe our research driven

THE GABELLI GLOBAL TELECOMMUNICATIONS FUND
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
--------------------------------------------------------------------------------
1.  ORGANIZATION.  The Gabelli Global  Telecommunications  Fund (the "Fund"),  a
series of Gabelli Global Series Funds, Inc. (the  "Corporation"),  was organized
on July 16,  1993 as a  Maryland  corporation.  The  Fund is a  non-diversified,
open-end  management  investment company registered under the Investment Company
Act of 1940,  as amended (the "1940 Act"),  and one of four  separately  managed
portfolios  (collectively,  the  "Portfolios")  of the  Corporation.  The Fund's
primary  objective  is  capital  appreciation.  The  Fund  commenced  investment
operations on November 1, 1993.

2. SIGNIFICANT  ACCOUNTING POLICIES.  The preparation of financial statements in
accordance with generally accepted accounting  principles requires management to
make estimates and assumptions  that affect the reported amounts and disclosures
in the financial  statements.  Actual results could differ from those estimates.
The following is a summary of significant  accounting  policies  followed by the
Fund in the preparation of its financial statements.

SECURITY  VALUATION.  Portfolio  securities  listed or  traded  on a  nationally
recognized securities exchange, quoted by the National Association of Securities
Dealers Automated Quotations, Inc. ("NASDAQ") or traded on foreign exchanges are
valued at the last sale price on that  exchange  as of the close of  business on
the day the  securities  are being  valued (if there were no sales that day, the
security is valued at the  average of the  closing  bid and asked  prices or, if
there were no asked  prices  quoted on that day,  then the security is valued at
the closing bid price on that day,  except for open short  positions,  which are
valued at the last  asked  price).  All  other  portfolio  securities  for which
over-the-counter  market  quotations  are  readily  available  are valued at the
latest average of the bid and asked prices.  Portfolio securities traded on more
than one  national  securities  exchange or market are valued  according  to the
broadest and most  representative  market,  as determined by Gabelli Funds,  LLC
(the  "Adviser").  Securities  and assets for which  market  quotations  are not
readily  available  are valued at their fair value as  determined  in good faith
under procedures  established by and under the general  supervision of the Board
of Directors. Short term debt securities with remaining maturities of 60 days or
less are valued at amortized cost, unless the Directors  determine such does not
reflect the  securities'  fair  value,  in which case these  securities  will be
valued at their fair value as  determined  by the  Directors.  Debt  instruments
having a  maturity  greater  than 60 days are  valued at the  highest  bid price
obtained from a dealer maintaining an active market in those securities. Options
are valued at the last sale price on the  exchange on which they are listed.  If
no sales of such options  have taken place that day,  they will be valued at the
mean between their closing bid and asked prices.

REPURCHASE  AGREEMENTS.  The Fund may  enter  into  repurchase  agreements  with
primary  government  securities dealers recognized by the Federal Reserve Board,
with member banks of the Federal Reserve System or with other brokers or dealers
that meet credit guidelines established by the Adviser and reviewed by the Board
of Directors.  Under the terms of a typical repurchase agreement, the Fund takes
possession  of an  underlying  debt  obligation  subject to an obligation of the
seller to repurchase,  and the Fund to resell,  the obligation at an agreed-upon
price and time, thereby  determining the yield during the Fund's holding period.
The Fund will always receive and maintain  securities as collateral whose market
value, including accrued interest,  will be at least equal to 100% of the dollar
amount  invested by the Fund in each  agreement.  The Fund will make payment for
such  securities  only upon  physical  delivery  or upon  evidence of book entry
transfer of the collateral to the account of the  custodian.  To the extent that
any repurchase transaction exceeds one business day, the value of the collateral
is marked-to-market on a daily basis to maintain the adequacy of the collateral.
If the seller defaults and the value of the collateral declines or if bankruptcy
proceedings are

NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)
--------------------------------------------------------------------------------
commenced  with  respect  to the  seller  of the  security,  realization  of the
collateral by the Fund may be delayed or limited.

FUTURES  CONTRACTS.  The Fund may engage in futures contracts for the purpose of
hedging  against  changes in the value of its  portfolio  securities  and in the
value of  securities  it  intends  to  purchase.  Upon  entering  into a futures
contract,  the Fund is required to deposit  with the broker an amount of cash or
cash equivalents equal to a certain  percentage of the contract amount.  This is
known as the "initial margin". Subsequent payments ("variation margin") are made
or  received by the Fund each day,  depending  on the daily  fluctuation  of the
value of the  contract.  The daily  changes  in the  contract  are  included  in
unrealized gains or losses. The Fund recognizes a realized gain or loss when the
contract is closed. At June 30, 2000, there were no open futures contracts.

There are several  risks in  connection  with the use of futures  contracts as a
hedging device. The change in value of futures contracts  primarily  corresponds
with the value of their underlying instruments, which may not correlate with the
change in value of the hedged investments.  In addition,  there is the risk that
the Fund may not be able to  enter  into a  closing  transaction  because  of an
illiquid secondary market.

SECURITIES  SOLD SHORT. A short sale involves  selling a security which the Fund
does not own. The proceeds  received for short sales are recorded as liabilities
and the Fund records an unrealized  gain or loss to the extent of the difference
between the proceeds  received  and the value of the open short  position on the
day of  determination.  The Fund records a realized  gain or loss when the short
position is closed out. By entering into a short sale, the Fund bears the market
risk of an unfavorable change in the price of the security sold short. Dividends
on short sales are  recorded as an expense by the Fund on the  ex-dividend  date
and interest expense is recorded on the accrual basis.

FORWARD  FOREIGN  EXCHANGE  CONTRACTS.  The Fund may engage in  forward  foreign
exchange contracts for hedging a specific transaction with respect to either the
currency in which the  transaction is denominated or another  currency as deemed
appropriate by the Adviser. Forward foreign exchange contracts are valued at the
forward  rate and are  marked-to-market  daily.  The  change in market  value is
included in  unrealized  appreciation/depreciation  on  investments  and foreign
currency transactions.  When the contract is closed, the Fund records a realized
gain or loss equal to the  difference  between the value of the  contract at the
time it was opened and the value at the time it was closed.

The use of forward foreign exchange contracts does not eliminate fluctuations in
the underlying prices of the Fund's portfolio securities,  but it does establish
a rate of exchange that can be achieved in the future.  Although forward foreign
exchange  contracts  limit the risk of loss due to a decline in the value of the
hedged  currency,  they also limit any potential  gain/(loss)  that might result
should  the value of the  currency  increase.  In  addition,  the Fund  could be
exposed to risks if the  counterparties  to the contracts are unable to meet the
terms of their contracts.

FOREIGN CURRENCY  TRANSLATION.  The books and records of the Fund are maintained
in United States  (U.S.)  dollars.  Foreign  currencies,  investments  and other
assets and liabilities  are translated  into U.S.  dollars at the exchange rates
prevailing  at the end of the  period,  and  purchases  and sales of  investment
securities,  income and expenses are translated at the exchange rate  prevailing
on the respective dates of such transactions. Unrealized gains and losses, which
result from changes in foreign exchange rates and/or changes in market prices of
securities,  have  been  included  in  unrealized  appreciation/depreciation  on
investments and foreign

currency transactions.  Net realized foreign currency gains and losses resulting
from changes in exchange rates include foreign currency gains and losses between
trade date and settlement date on investment  securities  transactions,  foreign
currency  transactions  and the  difference  between the amounts of interest and
dividends  recorded on the books of the Fund and the amounts actually  received.
The  portion of foreign  currency  gains and losses  related to  fluctuation  in
exchange rates between the initial trade date and subsequent  sale trade date is
included in realized gain/(loss) on investments.

SECURITIES  TRANSACTIONS  AND INVESTMENT  INCOME.  Securities  transactions  are
accounted  for on the  trade  date  with  realized  gain or loss on  investments
determined  by using the  identified  cost method.  Interest  income  (including
amortization  of premium  and  accretion  of  discount)  is  recorded as earned.
Dividend income is recorded on the ex-dividend date.

DIVIDENDS AND  DISTRIBUTIONS  TO  SHAREHOLDERS.  Dividends and  distributions to
shareholders  are recorded on the ex-dividend  date.  Income  distributions  and
capital  gain  distributions  are  determined  in  accordance  with  income  tax
regulations which may differ from generally accepted accounting principles.These
differences  are  primarily  due to differing  treatments of income and gains on
various investment securities held by the Fund, timing differences and differing
characterization of distributions made by the Fund.

EXPENSES.  Certain  administrative  expenses are common to, and allocated among,
the  Portfolios.  Such  allocations  are made on the  basis of each  Portfolio's
average  net  assets  or other  criteria  directly  affecting  the  expenses  as
determined by the Adviser.

PROVISION  FOR  INCOME  TAXES.  The Fund  intends  to  continue  to qualify as a
regulated  investment company under Subchapter M of the Internal Revenue Code of
1986, as amended. As a result, a Federal income tax provision is not required.

Dividends and interest from non-U.S.  sources received by the Fund are generally
subject  to  non-U.S.  withholding  taxes  at  rates  ranging  up to  30%.  Such
withholding  taxes may be reduced or  eliminated  under the terms of  applicable
U.S. income tax treaties, and the Fund intends to undertake any procedural steps
required to claim the benefits of such  treaties.  If the value of more than 50%
of the Fund's total  assets at the close of any taxable year  consists of stocks
or securities of non-U.S.  corporations,  the Fund is permitted and may elect to
treat any non-U.S. taxes paid by it as paid by its shareholders.

3.  INVESTMENT  ADVISORY  AGREEMENT.  The Fund has  entered  into an  investment
advisory  agreement (the "Advisory  Agreement")  with the Adviser which provides
that the Fund will pay the Adviser a fee,  computed  daily and paid monthly,  at
the annual rate of 1.00% of the value of the Fund's average daily net assets. In
accordance  with the  Advisory  Agreement,  the  Adviser  provides a  continuous
investment program for the Fund's portfolio,  oversees the administration of all
aspects of the Fund's  business  and  affairs and pays the  compensation  of all
Officers and Directors of the Fund who are its affiliates.

4.  DISTRIBUTION  PLAN. The Fund's Board of Directors has adopted a distribution
plan (the "Plan")  pursuant to Rule 12b-1 under the 1940 Act. For the six months
ended June 30, 2000, the Fund incurred  distribution  costs payable to Gabelli &
Company,  Inc.,  an affiliate of the Adviser,  of $593,251 and $12 for Class AAA
and Class A,  respectively,  or 0.25% of average  daily net  assets,  the annual
limitation  under the Plan. Class B and Class C incurred  distribution  costs of
$66 and $20,  respectively,  or 1.00% of average  daily net  assets,  the annual
limitation under the Plan. Such payments are accrued daily and paid monthly.

9. NEW SHARE  CLASSES.  The Board of Directors of the Fund approved a Rule 18f-3
Multi-Class Plan relating to the creation of three additional  classes of shares
of the Fund -- Class A Shares, Class B Shares and Class C Shares (the "New Share
Classes"). The existing class of shares was redesignated as Class AAA Shares. In
addition,  the Board has also  approved  an Amended  and  Restated  Distribution
Agreement, Rule 12b-1 plans for each of the New Share Classes and an Amended and
Restated  Plan of  Distribution  for the  existing  class of shares  (Class  AAA
Shares).  The New Share  Classes were offered to the public as of March 1, 2000.
Class A shares are subject to a maximum front-end sales charge of 5.75%. Class B
shares are subject to a contingent  deferred sales charge (CDSC) upon redemption
within  six  years of  purchase.  The  applicable  CDSC is equal to a  declining
percentage  of the  lesser  of the net  asset  value  per  share  at the date of
original  purchase  or at the date of  redemption,  based on the  length of time
held. Class C shares are subject to a 1% CDSC for two years after purchase.
