TO OUR SHAREHOLDERS,

      Convertible  stocks and bonds are hybrid  securities.  Because they can be
converted into common stock,  performance will be impacted by the dominant trend
in the  equity  markets.  However,  due to  their  significantly  higher  yield,
performance is also influenced by the direction of the bond market. In the third
quarter of 2002, with the stock market tumbling,  the equity  characteristics of
converts  continued  to restrain  performance.  However,  the strong bond market
helped support  convertible  securities prices. We invest in converts we believe
to have  two-thirds the upside  potential of the underlying  stock and one-third
the downside  risk.  Once again,  comparing the Gabelli  Convertible  and Income
Securities  Fund's (the  "Fund's")  performance  this  quarter to the Standard &
Poor's ("S&P") 500 Index, our risk appraisals have proven accurate.

RIGHTS OFFERING 2002

      Your Board of Directors has announced a transferable rights offering.  The
Fund is offering  shareholders one  transferable  right for each share of common
stock held as of the record date.  Three rights will be required to purchase one
additional  share  at a  discounted  price  to the  market  value  and  free  of
commission.  Shareholders who fully exercise their primary  subscription  rights
may  oversubscribe  for  any  additional  amount  of  shares  they  wish.  These
oversubscription  shares  will be  distributed  based on a  pro-rata  allocation
formula.  The  rights  offering  will be made only by means of a  prospectus.  A
prospectus  describing  the rights  offering in greater detail will be mailed to
shareholders separately.

WHAT'S RIGHT ABOUT RIGHTS

      To raise additional  capital,  rights offerings have  historically  been a
fair and efficient method.  This method is widely used in England. A traditional
rights offering allows an issuer's  shareholders to participate  directly in the
growth  of  that  issuer  by  purchasing  additional  common  shares  at  a  set
subscription  price. We discuss some of the basic issues of rights offerings and
how they relate to the Gabelli  Convertible  and Income  Securities  Fund in the
following question and answer format.

RIGHTS OFFERING - Q&A

Q: WHAT ARE RIGHTS?
      Rights are privileges  granted to existing  shareholders  of a corporation
(in our case the Gabelli Convertible and Income Securities Fund) to subscribe to
shares of a new issue of common stock. These rights represent short-term options
granted by the corporation which the shareholder has the option of exercising.

Q: WHAT IS THE HISTORY OF RIGHTS OFFERINGS?
      Rights  offerings  have been used in  Europe  since the late 17th  century
following the  commencement  of the London Stock  Exchange.  In England,  rights
offerings are commonplace and  well-regarded by  shareholders,  and represent an
integral part of its capital markets.  While underwritten  public offerings have
been the preferred method of raising capital in the U.S.,  rights offerings have
become more understood and more widely used.  Today,  rights  offerings are even
more common in the U.S.  and we expect that their  frequency  and  effectiveness
will increase.

Q: WHAT IS A RIGHTS OFFERING AS IT RELATES TO CLOSED-END FUNDS?
      A  rights  offering  is  an  opportunity  for   shareholders  to  purchase
additional  shares of a publicly  traded  company or mutual  fund at a specified
price--the   "subscription   price"--with  a  nominal  commission.   To  attract
shareholder interest, the subscription price is set at a discount to the current
market  price.  Although  shareholders  are not required to purchase  additional
shares, they are given the opportunity,  or "right", to purchase shares based on
the number of underlying  shares they own on the record date.  Rights may either
be  transferable  or  non-transferable  and  the  offering  may  or  may  not be
underwritten  with a commitment by the underwriter to buy what is not subscribed
for.

Q: WHAT ARE TRANSFERABLE RIGHTS VERSUS NON-TRANSFERABLE RIGHTS?
      Non-transferable  rights  have  no  value  other  than  that  they  may be
exercised and do not trade on any exchange.

      Transferable   rights   may  trade  on  an   exchange   and   afford   the
non-subscribing  shareholder  the option of selling their rights on the exchange
or through  the  transfer  agent.  Selling the rights  allows a  non-subscribing
shareholder to recoup much of the potential dilution that may otherwise occur. A
non-transferable  rights  offering  does  not  permit  such  an  offset  so that
non-subscribing shareholders could experience full dilution.

Q: HOW IS A RIGHTS OFFERING BENEFICIAL TO SHAREHOLDERS?
      The Gabelli  Convertible and Income  Securities Fund shareholder  benefits
from the opportunity to purchase  additional shares with no commission if shares
are held directly  with the Fund or, in some  instances,  with a nominal  charge
from their  broker.  Thus, an investor is able to put more  financial  assets to
work in an  investment  discipline  in which  she or he  believes  and which has
performed well over an extended  period of time. The additional  capital that is
raised  by the  Fund  is used to  position  the  portfolio  to more  fully  take
advantage of new investment opportunities. Increasing the asset size of the Fund
may also result in lowering the Fund's fixed expenses as a percentage of average
net assets.

Q: HOW IS THE GABELLI  CONVERTIBLE  AND INCOME SECURITIES FUND'S RIGHTS OFFERING
BETTER THAN OTHER RIGHTS OFFERINGS BY CLOSED-END FUNDS?
      There are two types of rights offerings a closed-end fund may use to raise
additional capital: the direct offering method and the firm-underwritten method.
The  Gabelli  Convertible  and  Income  Securities  Fund is  utilizing  a direct
offering  method to realize the relative cost  advantages  associated  with this
approach as compared to a  firm-underwritten  method.  A direct  offering avoids
costly underwriting and distribution service fees that lessen shareholder value.

                                       2

Q: ARE THE SHAREHOLDERS IN FAVOR OF RIGHTS OFFERINGS?
      We have received  numerous requests from the shareholders of our Funds for
rights offerings.  Our shareholders have been  overwhelmingly in favor of rights
offerings  and look forward to future ones.  This  interest was evidenced by the
oversubscribed rights offerings that the Gabelli Equity Trust had in 1991, 1992,
1993, 1995 and 2001. Additional  confirmation is evident from the Gabelli Global
Multimedia   Trust's  (which  was  spun-off  from  the  Equity  Trust  in  1994)
oversubscribed rights offerings in 1995 and 2000 and the Gabelli Utility Trust's
(which  was  spun-off  from the  Equity  Trust in  1999)  oversubscribed  rights
offering in 2002.  This interest was further  confirmed with the response to the
Gabelli Equity Trust shareholder vote in 1993 in which shareholders voted 90% in
favor to provide rights offerings.

Q: WERE  SHAREHOLDERS  ABLE  TO  SELL THEIR RIGHTS IN PAST RIGHTS OFFERINGS FROM
GABELLI FUNDS?
      Yes,  registered  shareholders  of the Gabelli  Equity Trust,  the Gabelli
Global  Multimedia Trust and the Gabelli Utility Trust had the option of selling
all or a portion of their rights by designating  this desire on the Subscription
Certificate  that  accompanied  the Prospectus.  The certificate  must have been
returned to Equiserve  Trust  Company by the end of the  offering  period at the
designated address.

      Those who held shares  through a broker  could simply have made the broker
aware of their desire to sell or exercise the rights.

Q: WHAT ARE THE TRANSACTION COSTS ON THE SALE OF THE RIGHTS?
      Rights may be sold through Equiserve Trust Company with no fees and only a
nominal  commission;  however,  certain brokerage firms may charge a transaction
fee to sell or exercise rights.

Q: WHAT IF MY TOTAL NUMBER OF RIGHTS IS NOT EVENLY DIVISIBLE BY THREE?
      The Gabelli  Convertible  and Income  Securities  Fund will  automatically
round up  shareholders'  rights  allocation so that the total number of rights a
shareholder  is  granted  is evenly  divisible  by three  (the  number of rights
required to purchase an additional share).

A PROMISE KEPT

      When we asked  the  shareholders  of the Fund to vote to  convert  from an
open-end  investment  company to a closed-end  fund in 1995,  we  expressed  our
intent to have the Fund's common shares track the Fund's net asset value.  Based
on  the  Fund's  consistent  and  above  average  annualized  performance  since
inception, we expected that such a Fund would trade at or above net asset value.
In addition,  over the past few years the Board of Directors  has taken  several
initiatives  to maintain the Fund's  public  market price at a level equal to or
exceeding  the  Fund's  net asset  value.  These  initiatives  included  a stock
repurchase plan, a managed 8% Distribution  Policy and the issuance of preferred
stock.

      We are pleased to report that  management kept its promise to shareholders
and the Fund is trading at a premium to net asset value. In fact, the Fund began
trading at a premium in February 2001 and has continued to trade above net asset
value,  ending the  quarter at a 28.96%  premium.  We have been able to preserve
shareholder wealth during a tough market environment.  We have been conservative
during the past year and it has paid off; now is the time to be aggressive.

                                       3

PREMIUM / DISCOUNT DISCUSSION

      As a refresher to our shareholders,  the price of a closed-end mutual fund
is  determined in the open market by willing  buyers and sellers.  Shares of the
Fund trade on the New York Stock  Exchange and may trade at a premium to (higher
than) net  asset  value  ("NAV")  (the  market  value of the  Fund's  underlying
portfolio) or a discount to (lower than) net asset value.  Of the 519 closed-end
funds in the U.S.,  approximately  27% currently trade at premiums to NAV versus
26% five years ago and 58% ten years ago.

      Ideally,  the Fund's market price will generally track the NAV. The Fund's
premium or  discount  to NAV  fluctuates  over time. Over our Fund's  7 1/2-year
history as a closed-end  fund, the range fluctuated from a 34% premium in August
2002 to a 17% discount in April 2000.  Beginning in early 2001, the market price
of the Fund exceeded the NAV and this premium has gradually increased since.

      "Mr.  Market" often provides  opportunities  to invest at a discount.  The
Fund has undertaken various  initiatives to narrow the discount when appropriate
through distribution policies, share repurchase programs and use of leverage.

      The  Fund's  long-term  investment  goal is to seek a high  level of total
return  through a combination  of current  income and capital  appreciation.  We
believe that our securities  selection process adds to the investment  equation.
We have a successful history of investment providing shareholders average annual
returns of 7.1% since inception.  However, it is important to remember that "Mr.
Market" is a pendulum  that  swings  both  ways.  As the market  moves away from
momentum  investing and back to basics, we believe that an excessive premium for
the Fund is not likely to be sustainable.

8.00% CUMULATIVE PREFERRED STOCK - MANDATORY 50% REDEMPTION

      As  authorized  by the  Board  of  Directors,  the Fund is  redeeming  50%
(600,000  Shares) of its  outstanding  8.00%  Cumulative  Preferred  Stock.  The
redemption  date is November 12, 2002 and the  redemption  price is $25.2555 per
Preferred  Share,  which consists of $25.00 per Preferred Share plus accumulated
and unpaid dividends through the redemption date of $0.2555 per Preferred Share.

      The redemption will be made pro rata from each Preferred Stock Shareholder
based on the respective  number of Preferred  Shares held by each such holder on
the redemption date. From and after the redemption date, the Preferred Shares to
be redeemed will no longer be deemed outstanding, dividends will cease to accrue
and all the rights of the Preferred  Shareholders  with respect to the Preferred
Shares to be  redeemed  will cease,  except the right to receive the  redemption
price.  Shareholders of record will be mailed a redemption  notice and letter of
transmittal.  The redemption  price will be paid only to  shareholders of record
who complete and sign the letter of transmittal and submit  certificates for the
number of Preferred Shares being redeemed.  New  certificates  will be issued to
replace any excess Preferred Shares submitted.

      The Board has also authorized the Fund to issue additional preferred stock
in the future.  The actual amount of capital to be raised, the dividend rate and
the timing of any new offering will be determined at a later date.  Any offering
will be made only by means of a  prospectus.  Depending on  prevailing  interest
rates,  shareholder  interest and other factors, the Board may determine to seek
to structure any such offering so as to enable shareholders to exchange all or a
portion of their Preferred  Shares for such newly issued preferred stock in that
offering.

      The Fund's 8.00%  Cumulative  Preferred Stock paid a cash  distribution on
September  26,  2002 of $0.50  per  share.  For the  twelve-month  period  ended
September 30, 2002, Preferred Stock shareholders received distributions totaling
$2.00,  the  annual  dividend  rate  per  share  of  Preferred  Stock.  The next
distribution is scheduled for December 2002.

NEW NAME: SAME APPROACH

      Effective August 1, 2002, the Gabelli Convertible  Securities Fund changed
its name to the Gabelli  Convertible and Income  Securities  Fund.  Although our
name has changed, our approach has not.

      The Fund will maintain its investment objective of seeking a high level of
total return through a combination of current income and capital appreciation.

      With this change,  the Fund will have more investment  flexibility to meet
the new Securities and Exchange Commission ("SEC") requirement (Rule 35d-1) that
funds invest at least 80% of their assets in the type of securities specified in
their name, under normal market  conditions.  The Fund has determined that being
required to invest 80% of its assets  strictly in convertible  securities is not
always optimal and, accordingly, has determined to change its name as it strives
to achieve its goal of  preserving  and enhancing  capital.  The Fund expects to
continue  its  practice of investing  in  convertible  securities  to the extent
attractive opportunities are available.

OUR OBJECTIVE

      Our mandate is to preserve and enhance our shareholders'  wealth through a
conservative  and  disciplined  approach to investing in convertible  and income
securities.  Our goal is to generate  profitable  returns in strong  markets and
protect   principal  in  weak   markets  by  taking   advantage  of  the  unique
characteristics of convertible securities.

      Our Fund is managed with a goal of achieving a 600-800  basis point spread
above  long-term  Treasury  yields.  We hope to generate  these returns over the
long-term. This is the type of performance that our Fund has been recognized for
and we  anticipate  will  continue  in  the  future.  Of  course,  there  are no
guarantees.

CONVERTIBLE SECURITIES ARE "HYBRIDS"

      It is important to understand our stock selection discipline because price
movement in the underlying  equity will  generally  have the greatest  impact on
convertible  securities pricing.  The convertible  securities market consists of
bonds,  debentures,  corporate  notes,  preferred  stocks and  warrants or other
similar  securities  which may be converted  into or exchanged  for a prescribed
amount of  common  stock or other  equity  security  of the same or a  different
issuer  within a  particular  period of time at a  specified  price or  formula.
Converts are "hybrid" securities that combine the capital appreciation potential
of equities  with the higher  yield of fixed  income  instruments.  Our strategy
incorporates  the  purchase  of  convertible  securities  that are  trading at a
premium above parity with the common stock but which generally  provide a higher
yield  and,  over time,  capital  appreciation.  We will also seek out  "busted"
converts,  where the underlying  common stock has dropped  significantly and the
values  of  both  the  conversion  privilege  and the  convert  are  down.  Such
securities  will provide  both high yields and  long-term  capital  appreciation
potential.

CONVERTIBLE MARKET OVERVIEW

      The convertible  market,  as measured by the Merrill Lynch All Convertible
Index, fell 8.2% during the third quarter.  This compared to a decline of 19.8%,
17.3%,  and  17.4%  by the  Nasdaq  Composite,  the S&P  500  and the Dow  Jones
Industrial Indices, respectively.  Poor corporate earnings, corporate governance
issues and  tensions  in the Middle East hurt equity  markets.  This  provoked a
flight   to   quality   as   registered   by  the  AA1   rated   Merrill   Lynch
Government/Corporate  Bond  Index,  which  rose 5.9%.  Conversely,  the B1 rated
Merrill  Lynch  U.S.  High  Yield  Master II Index  fell 3.0% as credit  spreads
widened.  This trend was reflected in the  convertible  market,  as  speculative
grade  convertibles  dropped 10.0%,  while  investment grade issues fell by only
7.4%. The average  convertible now has the highest  conversion premium on record
of 106% (up from 75% last quarter), a current yield of 4.67% (versus 4.22%), and
a credit rating of BBB-, unchanged from last quarter.

                                       6

      The size of the  convertible  market  fell 11% during the  quarter to $197
billion  due  primarily  to poor price  performance.  Weak equity  markets  have
stunted  the new issue  market.  Year to date,  new deals  have  totalled  $44.6
billion versus $74.5 billion  during the comparable  period last year, a decline
of 40%. By product  type,  new  issuance  continues  to be dominated by the more
equity-like  structures  as  companies  strive  to  repair  balance  sheets  and
investors search for low premium  convertibles  with attractive  current yields.
Year to date,  convertible preferred stock and mandatory convertible  securities
constituted  44% of total new issue activity versus only 19% during all of 2001.
Finally, in an effort to capitalize on currently depressed levels, companies are
buying back their issues in the open market. Year to date, of the $21 billion in
redemptions, 29% (or $6 billion) represent company repurchases.

      Only two sectors rose during the  quarter:  Consumer  Staples  (+1.0%) and
Telecommunications   (+0.7%).   Although   down   27.8%   year  to   date,   the
Telecommunications  sector rose during the quarter due to the strong performance
of Nextel Communications and Level 3 Communications.  This sector makes up 6% of
the convertible market.  Utilities were the worst performing sector both for the
quarter  (-24.1%) and the year to date (-34.7%).  The sector was hit by the poor
performance  of issues like Calpine,  Duke Energy,  and Mirant.  Meanwhile,  the
Materials  (-17.4%) and Technology sectors (-14.8%) remained weak. These sectors
represent  4% and 20% of the  convertible  market  respectively.  The  Materials
sector was adversely  affected by declines at Freeport Copper,  Georgia Pacific,
and Sealed Air, which suffered from renewed concerns about asbestos liabilities.
Finally, busted convertibles (-4.1%), being less equity sensitive,  outperformed
balanced  (-14.9%)  and equity  sensitive  convertibles  (-16.0%),  while  small
capitalization   issuers   (-16.3%)   succumbed   to  mid   (-10.6%)  and  large
capitalization issuers (-4.4%) and value (-10.2%) gave in to growth (-5.9%).

COMMENTARY

THE ECONOMY: LIMPING ALONG

      Federal Reserve Board ("Fed")  Chairman  Greenspan  remains  confident the
economy is still on a modest growth path.  Equity  investors  aren't so sure. On
balance,  the  economic  data has been mixed.  Consumer  spending  has  remained
buoyant.  Housing  starts,  existing  home sales and auto sales are still  quite
healthy.  Retail  sales  have  held  up  well,  despite  the  drag  from  rising
unemployment and the toxic impact of the wealth effect.

      Why is the economy  treading  water?  The business sector is acting like a
deer caught in headlights. A dearth of capital spending continues to drag on the
economy and uncertainty  regarding Iraq is also probably  having an impact.  Oil
hovering over $30 per barrel is taking its toll on all. We saw impressive  Gross
Domestic Product ("GDP") growth in the first half of the year as companies began
rebuilding  inventories  depleted  during the  recession and in the aftermath of
9/11.  Then the  re-stocking  of shelves was put on hold as  corporate  managers
devoted much of their time, energy and resources to making sure their companies'
books were in good order and/or  shoring up balance  sheets.  As these tasks are
completed,  we should see the inventory  rebuilding cycle resume and the economy
make more  meaningful  progress,  though the West Coast dock  lock-out will mute
results. As corporate managers gain confidence that the recovery is for real, we
should also see a modest  up-tick in capital  spending take some of the economic
burden off the American  consumer's broad shoulders.  However,  in order for the
world  economies to gain  traction,  oil would need to be  plentiful  and priced
below $25 per barrel.

      Higher energy prices are essentially a tax on virtually every business and
consumer.  At around $30 per  barrel,  oil appears to be  discounting  a serious
disruption in supply resulting from a potential war in Iraq, and closer to home,
a threatened  strike by Mexican oil workers.  It is  impossible  to predict what
will happen in the coming months.  However, should the supply lines remain open,
we believe  oil prices will come down from  current  levels and no longer pose a
serious threat to a global economic recovery. Longer term, the U.S. must consume
less and find alternative ways to power our ubiquitous automobile.

THE STOCK MARKET: WHERE IS THE BOTTOM?

      When and where will the stock market  bottom out? We wish we knew. At this
juncture, stock prices appear to be discounting most if not all of the bad news.
In July and again in September, we witnessed the kind of near panic selling that
usually  foreshadows market bottoms. We believe the old adage that "bull markets
climb a wall of worry," and it is apparent that  investors  have plenty to worry
about. We also echo our observation  that the two ingredients for a stock market
recovery  -- low  interest  rates and a better  earnings  environment  -- are in
place.

PUTTING HUMPTY DUMPTY BACK TOGETHER

      When past market bubbles burst,  lots of debris washed ashore.  This time,
the bubble was bigger  and the  debris  was more  hideous  and more  widespread.
Accountants,  analysts,  and investment bankers (among others) lost their checks
and balances and did not act as safety nets and buffers.

      We are in a camp that believes that securities analysts do a terrific job.
Beginning in May of 1975, a payment  mechanism for research was removed with the
collapse  of fixed  price  commissions.  The  conflicts  in the late  1990s  are
directly traceable to "May Day." Where next? When we joined Wall Street in 1967,
research that was performed on a brokerage firm's investment  banking client was
identified as such. To get back there is an easy fix. Regulation Fair Disclosure
("FD") already put analysts back on the fundamental research track.

      Accountants  should not perform  services beyond audit  functions,  except
where the fee is small relative to the audit engagement.

      Perhaps we need to revisit the  Glass-Steagall  Act. The safeguards put in
place by that Act were there for a reason.

      All in all, we believe  that most  corporate  managers we see come to work
every day to grow the intrinsic value of their  enterprise and work hard to have
the public stock track the underlying value of the business.

      Our job remains the same -- to ferret out those  companies that Mr. Market
puts on the bargain counter.

ALL HAIL BONDS!

      Although  corporate bonds have not performed  nearly as well as Treasuries
(traditionally  investors' favorite port during stock market storms),  they have
delivered positive returns.  Preferred stocks,  which trade more like bonds than
stocks,  have  also  held up  well.  Consequently,  it is no  surprise  that our
portfolio of convertible bonds and convertible  preferreds  outperformed  equity
indices by such a wide margin.

INVESTMENT SCORECARD

      This  quarter's best  performing  holdings came from a variety of industry
groups including:  telecommunications  (Nextel Communications,  AT&T, and United
States  Cellular);  auto parts (WHX Corp.  and Allen Group);  and  manufacturing
(Thermo Fibertek).

      Among our biggest  disappointments  were  telecom  equipment  manufacturer
Lucent  Technologies,  utilities  company  Progress  Energy,  and amusement park
operator Six Flags.

LET'S TALK CONVERTS

      The following are specifics on selected  convertible holdings of our Fund.
Favorable  earnings  prospects do not  necessarily  translate  into higher stock
prices,  but they do express a positive  trend that we believe will develop over
time.

CITIZENS  COMMUNICATIONS  CO.  (CZN) (5.00% CV. PFD.) is one of the nation's top
three largest  independent local exchange carriers with about 2.5 million access
lines after completion of a $3.4 billion acquisition of almost 1.1 million lines
from  Frontier.  This and several  other  recent  acquisitions,  accompanied  by
divestitures of its utilities  operations,  have  repositioned  the company as a
pure telecommunications carrier. After recent completion of the tender offer for
19% of  shares  that it  already  did not  own,  CZN now owns  100% of  Electric
Lightwave  Inc., a competitive  carrier with fiber optic  networks  covering the
Western part of the U.S. The company is now focused on strengthening its balance
sheet by using the strong free cash flow of its local phone  operations  as well
as any potential  proceeds from the sale of the remaining utility  operations to
pay down debt.

FRANKLIN  RESOURCES  INC. (BEN) (ZERO COUPON,  05/11/31) is a financial  holding
company that provides  investment  advisory and management  services through its
Franklin, Templeton, Mutual Series, Bissett, and Fiduciary investment management
groups as well as banking  services  though  its  banking/finance  segment.  The
company has about $248 billion in assets under management across a wide-range of
investment products and styles.  Finally,  the company operates in 37 offices in
29 countries,  and is focused on further expanding its international  investment
management  business,  particularly  as pension systems are reformed in numerous
countries around the world.

GENERAL MOTORS CORP.  (GM) (5.25% CV. PFD.,  SER. B; 4.50% CV. PFD.,  SER. A) is
the largest  producer of motor vehicles in the world,  with unit sales of over 8
million cars,  trucks,  and commercial  vehicles in 2001 alone.  The company has
operating  subsidiaries in North America,  Europe,  Latin America, and Asia, and
equity  interests  in  manufacturers  in Europe (Fiat Auto  Holdings)  and Japan
(Isuzu, Suzuki,  Subaru).  General Motors Acceptance Corporation provides retail
and wholesale  financing to consumers and dealers worldwide,  as well as vehicle
leasing, mortgage, and insurance products. The company's Hughes Electronics (GMH
- $9.15 - NYSE) subsidiary provides direct-to-home satellite television services
to over 10 million consumers in the U.S. under the DirecTV brand name.

HILTON HOTELS CORP. (HLT) (SUB. DEB. CV., 5.00%,  05/16/06) is recognized as one
of the world's preeminent hospitality companies.  Hilton develops, owns, manages
and franchises hotels,  resorts and vacation ownership properties.  Based on the
number of hotel rooms,  Hilton is the nation's  third largest  lodging  company.
Hilton's hotel system  includes  approximately  2,000  properties  totaling over
333,000 rooms  worldwide.  The Company's  hotel brands  include  Hilton,  Hilton
Garden Inn,  Doubletree,  Embassy  Suites  Hotels,  Hampton  Inn,  Hampton Inn &
Suites,  Homewood Suites by Hilton,  Conrad,  and Harrison  Conference  Centers.
Flagship properties include the Waldorf Astoria,  the Hilton Chicago, the Hilton
Hawaiian Village Beach Resort & Spa and the Palmer House Hilton.  HLT formalized
a marketing  alliance with the British  company Hilton Group plc (HG.L - $2.52 -
London  Stock  Exchange),  owner of Hilton  International,  in  January  1997 to
reunite the Hilton name worldwide for the first time in over 30 years.

NEXTEL  COMMUNICATIONS INC. (NXTL) (5.25%,  01/15/10;  6.00%,  06/01/11;  4.75%,
07/01/07) is one of two remaining  independent national wireless carriers in the
U.S.,  servicing  over 10 million mostly  high-value  business  subscribers  and
controlling  wireless  licenses  covering  over 235  million  people.  Nextel is
differentiating itself by offering its unique direct-connect feature that allows
instant  two-way voice  communication.  Since the beginning of 2002, the company
has used a combination of cash and stock to reduce its debt by over $1.8 billion
while still maintaining a healthy cash balance.  Nextel has submitted a proposal
to the Federal  Communications  Commission  ("FCC") to re-allocate  its spectrum
portfolio at the radio frequencies also used by the public safety organizations.
The FCC  decision  is  expected  by the  end of 2002  and,  if  approved,  would
significantly strengthen Nextel's competitive position.

                                       9

NORTHROP GRUMMAN CORP. (NOC) (7.00% CV. PFD., SER. B) is a defense  technologies
company, specializing in electronics and systems integration. Their products are
at the heart of the  network-centric  integrated  battle  management  systems of
modern warfare. The Global Hawk unmanned aerial  reconnaissance system is one of
their most  recent  products.  They also  produce  nearly 60% of the  Pentagon's
airborne  radar  systems  and are well  positioned  in  missile  defense.  After
acquiring  Litton  Industries  and Newport News,  the company is now the world's
largest  naval  shipbuilder,  with  expertise  in  every  class of  nuclear  and
non-nuclear vessel. In July 2002, TRW, the aerospace and information  technology
company,  agreed to be acquired for $7.8 billion in stock. The pending deal will
make  Northrop a leader in military  satellites,  missile  systems,  and systems
integration.

ROBBINS & MYERS INC. (RBN) (SUB. DEB. CV., 6.50%,  09/01/03) is an international
manufacturer of industrial mixing  equipment,  glass-lined  vessels,  industrial
pumps and corrosion  resistant  products serving the process  industries such as
specialty  chemicals,  pharmaceuticals,  water treatment,  oil and gas, food and
beverage.  Recently the company  completed the acquisition of Romaco,  a company
with annual sales of approximately $150 million that manufactures the packaging,
printing and processing of pharmaceutical  products.  Romaco provides horizontal
integration  to Robbins'  mixer and vessel  businesses  and the  acquisition  is
expected  to be  accretive  to  earnings.  With  Romaco,  40% of Robbins & Myers
revenues  are in the  pharmaceutical  market that is generally  stable,  with an
average 6% to 8% rate of  growth.  The  company's  remaining  businesses  are in
specialty  chemical  (26%),  energy (20%),  water and wastewater  (4%) and other
industries.  Management's  use of its  strong  cash  flow to make  complementary
acquisitions  makes  Robbins & Myers an  attractive  company in a  consolidating
industry.

SEQUA CORP.  (SQA) ($5.00 CV. PFD.) is a diversified  company with businesses in
aerospace,  pre-paint metal, specialty chemical, printing and cannery equipment.
Chromalloy Gas Turbine,  Sequa's aerospace business,  is the largest independent
supplier of aftermarket  parts for the overhaul and repair of jet and industrial
gas  turbine  engines.  We believe  this  business  is  attractive  to  original
equipment engine manufacturers like General Electric and Pratt & Whitney who are
looking to grow their replacement  parts business.  With roughly $800 million in
revenues,  we estimate  Chromalloy's  private market value to be near the entire
public value of Sequa.

STANDARD  MOTOR  PRODUCTS  INC.  (SMP)  (SUB.   DEB.  CV.,   6.75%,   07/15/09),
headquartered  in Long Island City, New York,  supplies  functional  replacement
parts for the engine management, electrical and climate control systems of cars,
trucks and buses.  The company  services all makes and models,  both new and old
cars, imported and domestic.  SMP has two primary divisions -- engine management
and  temperature control --  and  believes it is the number one  supplier to the
North American aftermarket in each of these lines.

STOCK REPURCHASE PLAN

      The Fund is authorized  to  repurchase up to 500,000  shares of the Fund's
outstanding common shares.  Pursuant to this stock repurchase plan, the Fund may
from time to time  purchase  shares of its capital stock in the open market when
the shares are  trading at a discount of 10% or more from the net asset value of
the shares.  In total,  through  September  30, 2002,  305,200  shares have been
repurchased in the open market under this stock  repurchase plan. No shares were
repurchased during the third quarter because the Fund traded at a premium to net
asset value throughout the quarter.

COMMON STOCK 8% DISTRIBUTION POLICY

      The Fund continues to maintain its 8% Distribution Policy whereby the Fund
pays out to common  stock  shareholders  8% of its average net assets each year.
Pursuant to this policy,  the Fund distributed  $0.20 per share on September 24,
2002. The next distribution is scheduled for December 2002.

                                       10

      Under the policy,  distributions  are made at the annual rate of 8% of the
average of the  calendar  quarter-end  net assets of the Fund's  common stock at
December 2001 and March, June, and September 2002. The Fund normally distributes
$0.20 per share to common stock shareholders in March, June, and September.  The
fourth quarter  distribution is a variable  adjusting  distribution in December.
The adjusting  distribution is the greater of the remaining portion of 8% of the
average  net assets to be  distributed  (8% of the  average  net assets less the
cumulative   amount  paid  in  March,   June,  and  September)  or  the  minimum
distribution  required by IRS regulations.  Each quarter, the Board of Directors
reviews the amount of any potential  distribution  based on the income,  capital
gains or capital available.

IN CONCLUSION

      True to form,  convertible securities held up relatively well as the stock
market  continued  to  slump in the  third  quarter.  Hopefully,  in the not too
distant future, we will have the opportunity to see convertibles  participate in
a more forgiving stock market.

                                   Sincerely,

                                   /S/ MARIO J. GABELLI

                         AUTOMATIC DIVIDEND REINVESTMENT
                        AND VOLUNTARY CASH PURCHASE PLAN

ENROLLMENT IN THE PLAN

      It is the policy of The Gabelli  Convertible  and Income  Securities  Fund
Inc.  ("Convertible  and  Income  Securities  Fund") to  automatically  reinvest
dividends. As a "registered"  shareholder you automatically become a participant
in the Convertible and Income Securities Fund's Automatic Dividend  Reinvestment
Plan (the "Plan").  The Plan authorizes the  Convertible  and Income  Securities
Fund to issue shares to participants  upon an income dividend or a capital gains
distribution  regardless  of whether  the shares are  trading at a discount or a
premium to net asset value. All  distributions to shareholders  whose shares are
registered in their own names will be automatically  reinvested  pursuant to the
Plan in additional  shares of the Convertible and Income  Securities  Fund. Plan
participants  may send their  stock  certificates  to  EquiServe  Trust  Company
("EquiServe")  to be held in their  dividend  reinvestment  account.  Registered
shareholders  wishing to receive  their  distribution  in cash must  submit this
request in writing to:

             The Gabelli Convertible and Income Securities Fund Inc.
                                  c/o EquiServe
                                 P.O. Box 43011
                            Providence, RI 02940-3011

      Shareholders  requesting this cash election must include the shareholder's
name and  address as they  appear on the share  certificate.  Shareholders  with
additional  questions  regarding  the  Plan  may  contact  EquiServe  at 1 (800)
336-6983.

      SHAREHOLDERS WISHING TO LIQUIDATE REINVESTED SHARES held at EquiServe must
do so in  writing  or by  telephone.  Please  submit  your  request to the above
mentioned  address  or  telephone  number.  Include in your  request  your name,
address  and  account  number.  The  cost  to  liquidate  shares  is  $2.50  per
transaction as well as the brokerage commission incurred.  Brokerage charges are
expected to be less than the usual brokerage charge for such transactions.

      If your  shares  are held in the name of a broker,  bank or  nominee,  you
should contact such institution. If such institution is not participating in the
Plan,  your  account  will  be  credited  with  a cash  dividend.  In  order  to
participate in the Plan through such institution, it may be necessary for you to
have your shares taken out of "street name" and  re-registered in your own name.
Once  registered  in  your  own  name  your  dividends  will  be   automatically
reinvested. Certain brokers participate in the Plan. Shareholders holding shares
in "street name" at participating institutions will have dividends automatically
reinvested.  Shareholders  wishing  a cash  dividend  at such  institution  must

Plan in lieu of cash dividends is determined in the following manner.  Under the
Plan,  whenever the market price of the Convertible and Income Securities Fund's
Common  Stock is equal to or  exceeds  net asset  value at the time  shares  are
valued for purposes of determining  the number of shares  equivalent to the cash
dividends  or capital  gains  distribution,  participants  are issued  shares of
Common Stock  valued at the greater of (i) the net asset value as most  recently
determined or (ii) 95% of the then current market price of the  Convertible  and
Income  Securities  Fund's Common Stock.  The valuation  date is the dividend or
distribution  payment  date or,  if that date is not a New York  Stock  Exchange
trading day, the next trading day. If the net asset value of the Common Stock at
the time of valuation exceeds the market price of the Common Stock, participants
will receive shares from the  Convertible  and Income  Securities Fund valued at
market price.  If the  Convertible  and Income  Securities Fund should declare a
dividend or capital gains distribution  payable only in cash, EquiServe will buy
Common Stock in the open market, or on the New York Stock Exchange or elsewhere,
for the participants' accounts, except that EquiServe will endeavor to terminate
purchases  in the open market and cause the  Convertible  and Income  Securities
Fund to issue shares at net asset value if,  following the  commencement of such
purchases,  the market  value of the Common  Stock  exceeds the then current net
asset value.

      The automatic  reinvestment  of dividends and capital gains  distributions
will not  relieve  participants  of any  income tax which may be payable on such
distributions.  A participant in the Plan will be treated for Federal income tax
purposes  as  having  received,  on a  dividend  payment  date,  a  dividend  or
distribution in an amount equal to the cash the participant  could have received
instead of shares.

      The Convertible and Income  Securities Fund reserves the right to amend or
terminate  the Plan as  applied  to any  voluntary  cash  payments  made and any
dividend or distribution paid subsequent to written notice of the change sent to
the  members  of the Plan at  least  90 days  before  the  record  date for such
dividend  or  distribution.  The  Plan  also may be  amended  or  terminated  by
EquiServe  on at least 90 days'  written  notice  to  participants  in the Plan.

VOLUNTARY CASH PURCHASE PLAN

      The  Voluntary  Cash  Purchase  Plan  is  yet  another   vehicle  for  our
shareholders  to  increase  their  investment  in  the  Convertible  and  Income
Securities  Fund. In order to  participate  in the Voluntary Cash Purchase Plan,
shareholders must have their shares registered in their own name.

      Participants in the Voluntary Cash Purchase Plan have the option of making
additional  cash payments to EquiServe for  investments in the  Convertible  and
Income Securities  Fund's shares at the then current market price.  Shareholders
may send an  amount  from $250 to  $10,000.  EquiServe  will use these  funds to
purchase  shares in the open  market on or about the 1st and 15th of each month.
EquiServe will charge each shareholder who participates  $0.75,  plus a pro rata
share of the brokerage  commissions.  Brokerage  charges for such  purchases are
expected to be less than the usual brokerage charge for such transactions. It is
suggested that any voluntary cash payments be sent to EquiServe, P.O. Box 43011,
Providence,  RI 02940-3011   such  that   EquiServe   receives   such   payments
approximately  10 days before the investment  date.  Funds not received at least
five days before the investment date shall be held for investment until the next
purchase  date. A payment may be withdrawn  without charge if notice is received
by EquiServe at least 48 hours before such payment is to be invested.

Voluntary Cash Purchase Plan,  brochures are available by calling (914) 921-5070
or by writing directly to the Convertible and Income Securities Fund.
