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.  With stocks
declining in the first  quarter as investors  pondered the  consequences  of war
with Iraq,  the equity  characteristics  of converts were a modest  negative for
performance.  However,  the strong  performance  of the  corporate  bond  market
enhanced  convertible  returns.  On a net asset value ("NAV") basis, the Gabelli
Convertible  and  Income  Securities  Fund  (the  "Fund")  gained  2.24% for the
quarter,  and with investors favoring more stable  income-producing  stocks, the
Fund's market price rose 12.93%.

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 547 closed-end
funds in the U.S.,  approximately  33% currently trade at premiums to NAV versus
26% five years ago and 60% 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 8-year history,
the range  fluctuated  from a 31%  premium in August  2002 to a 17%  discount in
April 2000. Since early 2001, the market price of the Fund has exceeded the NAV.

      "Mr.  Market" often provides  opportunities  to invest at a discount.  The
Fund has  various  initiatives  in place to narrow any  existing  discount  when
appropriate through distribution policies, share repurchase programs and the 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 7.4% 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.

6.00% CUMULATIVE PREFERRED STOCK / SERIES C AUCTION RATE CUMULATIVE PREFERRED
STOCK

      As authorized  by the Board of Directors,  the Fund redeemed the remaining
50% (600,000  Shares) of its  outstanding  8.00%  Cumulative  Preferred Stock in
conjunction  with the issuance of two new series of Preferred  Stock.  The 8.00%
Preferred  Stock was  redeemed on February  11,  2003 at a  redemption  price of
$25.25 per  Preferred  Share,  which  consists of $25.00 per share of  Preferred
Stock (the liquidation value), plus accumulated and unpaid dividends through the
redemption  date of  $0.25  per  share of  Preferred  Stock.  The new  preferred
issuance  consists of $25 million of 6.00% Series B Cumulative  Preferred  Stock
and $25  million  of Series C  Auction  Rate  Cumulative  Preferred  Stock.  The
proceeds raised will be used for investment purposes.

      The 6.00% Series B Preferred  Shares are rated "Aaa" by Moody's  Investors
Service,  Inc. The 6.00% Series B Preferred  Shares are perpetual,  non-callable
for five  years and were  issued at $25 per  share.  Distributions  will be paid
quarterly  beginning on June 26, 2003. The 6.00% Series B Preferred Shares trade
on the New York Stock Exchange under the symbol "GCV Pr B". The Series C Auction
Rate Preferred  Shares are rated "Aaa" by Moody's  Investors  Service,  Inc. and
"AAA" by Fitch,  Inc. The Series C Preferred  Shares are perpetual and generally
are  callable at any time without  premium.  The initial  dividend  rate for the
Series C Preferred  Shares was 1.30% for the period  ending March 25, 2003.  The
dividend rates for subsequent  periods will be determined by an auction process.
The Series C Auction Rate Preferred Shares do not trade on an exchange.

      It  should  be noted  that the  Investment  Adviser  will  not  receive  a
management fee on the  incremental  assets raised unless the total return of the
Fund to common  shareholders  during any year exceeds the  dividend  rate of the
preferred  stock,  including the costs of any interest  rate swap  agreement the
Fund may enter into to protect against short-term interest rate increases.

OUR OBJECTIVE

      Our mandate is to preserve and enhance our shareholders'  wealth through a
conservative and disciplined approach to convertible  securities investing.  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,  gained  3.07% during the first  quarter.  This  outperformed  the equity
markets as the Nasdaq gained a modest 0.42% while both the Dow Jones  Industrial
Average  and the  Standard & Poor's  ("S&P")  500 Index fell by 3.76% and 3.15%,
respectively.  Most  of  this  out  performance  was  due to the  tightening  of
speculative  grade credit  spreads.  The B1 rated  Merrill Lynch U.S. High Yield
Master II Index rose by 7.14% during the quarter as credit spreads  tightened by
13% from 871 basis points to 757 basis points. Conversely, the AA1 rated Merrill
Lynch   Government/Corporate   Bond  Index  gained  just  1.11%.  Equity  market
volatility,  as measured by the Chicago Board Option Exchange ("OEX") Volatility
Index, rose by only 3 points during the quarter to 33, but vacillated between 26
and 40. It had been as high as 50% in July 2002.  These trends were reflected in
the  convertible   market  as  speculative  grade   convertibles   significantly
outperformed  their  investment-graded  counterparts  during the quarter gaining
6.19% versus a decline of 0.04%,  respectively.  The domestic convertible market
is composed of 39% speculative grade credits,  48% investment grade credits, and
13% non-rated credits.

      As expected, weak equity performance caused the average conversion premium
to expand as convertibles  outperformed  their underlying  equities.  During the
quarter, the average conversion premium rose from 98% to 103%. At the same time,
the  average  current  yield  fell  slightly  from 4.3% to 4.1% while the credit
quality remained constant at BB+.

      During the first quarter, the size of the convertible market grew by 5% to
$224 billion assisted by positive net new issuance of $7 billion. However, total
new issuance remains muted with only $14 billion year to date versus $30 billion
over the same period last year.  Investors' demand for current yield in the form
of convertible paper has permitted issuers to benefit from very favorable terms.
Theoretical  cheapness  at issue has now dropped to 0.74% from 3.23% in February
with the average  conversion  premium  rising to 45% from 31% in January.  In an
effort to bring  issuers  to market,  Mandalay  Resorts  succeeded  in pricing a
convertible/warrant structure on a record 100% premium.

COMMENTARY

THE POST-IRAQ ECONOMY AND MARKET

      As we prepare this letter, U.S.-led coalition forces control almost all of
Iraq and the quick and  decisive  victory  most of the world  hoped for has been
achieved.  Investor  focus is already  shifting  from the war to the economy and
corporate  earnings.   Over  the  next  several  months,  we  will  see  whether
uncertainty regarding Iraq has been the primary restraint on the economy.

      Recently released economic data has been troublesome. Institute for Supply
Management   ("ISM")   barometers   indicate  that  manufacturing  and  services
contracted in March.  New jobless  claims are again  trending  higher,  consumer
sentiment  readings  remain near  10-year  lows,  consumer  spending is off, the
robust new housing market is showing signs of softening, and business investment
and capital spending,  which had shown modest  improvement in the fourth quarter
of 2002, has stalled.

      Importantly,  however,  oil prices  have come way down from their  pre-war
peaks and we believe  will  eventually  settle in the mid-$20 per barrel  range.
This is the equivalent of an enormous tax cut for  individuals  and  businesses.
Victory in Iraq has also increased President Bush's political capital, improving
the  chance  that we will see at  least  some of the  Administration's  economic
stimulus package make it through  Congress.  Finally,  the Federal Reserve Board
still has leverage in the form of another rate cut if needed  and/or the ability
to inject additional liquidity into the financial system. Our conclusion is that
the economy  will  regain its  footing and stocks can make some  progress in the
second half of 2003.

                                       4

      Longer term,  our outlook for the economy and markets has not changed.  We
are still  anticipating  an extended  period of modest  economic  and  corporate
profit growth.  Over the next five years,  we expect  annualized  Gross Domestic
Product  ("GDP")  growth in the 3% range and 6%  annualized  growth in corporate
profits.  If interest rates remain  relatively low, this would likely  translate
into  stock  market  gains in line  with  earnings  growth.  If  rates  increase
significantly, price/earnings multiple contraction would likely result in a flat
market.  In  either  scenario,  we  believe  investors  will  continue  to favor
income-generating securities.

A STABLE BOND MARKET

      Corporate  bonds performed quite well in the first quarter and yields have
come down. If inflation  remains subdued and the economy  continues along a slow
growth  path,  we should enjoy a  relatively  stable bond market with  dividends
being the primary  component  of total  return.  If the economy  reflates in the
quarters following the war, bonds could be vulnerable.

INVESTMENT SCORECARD

      The  best  performing  sectors  during  the  quarter  included  technology
(+9.2%),  utilities (+6.4%) and  telecommunications  (+5.9%). The Fund benefited
from its  holdings in Lucent,  Mirant,  Nextel and Sealed Air.  Lagging  sectors
included industrials (-1.9%), transportation (-0.46%) and consumer discretionary
(-0.35%).  In general,  our utilities  investments  disappointed  with Northeast
Utilities and Progress Energy among our poorest  performers.  In the year ahead,
convertibles  should  benefit from a combination of attractive  current  income,
continued credit spread tightening and capital appreciation.

LET'S TALK CONVERTS

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

AGERE SYSTEMS INC.  (AGR'A) (SUB. DEB. CV., 6.50%,  12/15/09) is a developer and
manufacturer  of  integrated  circuits  ("ICs")  that  access,  move  and  store
information  in a broad  range of  computing  and  communications  applications.
Agere, based in Allentown,  PA, was spun-off from Lucent Technologies in June of
2002.  The company  has a strong  product mix and  attractive  end markets  that
should  allow the company to deliver  growth as the  semiconductor  and personal
computer  cycles  return to  normalcy.  Agere  continues to maintain its leading
position in the  computing  and  wireless  markets  including  the  Wireless LAN
(802.11) arena, an emerging technology that enables mobile broadband access from
almost anywhere.

BROADWING  INC.  (BRW)  (6.75% CV.  PFD.,  SER.  B) located in  Cincinnati,  OH,
received its new name in 1999 when local phone provider  Cincinnati  Bell made a
$3.2  billion   acquisition  of  IXC  Communications  and  gained  access  to  a
nation-wide all optical fiber network.  Broadwing's  Cincinnati-based operations
include one  million  local phone  lines and about  465,000  wireless  customers
through  its 80%  ownership  of a  wireless  joint  venture  with AT&T  Wireless
Services (AWE - $6.60 - NYSE).  Broadwing  recently announced its intent to sell
broadband  operations.  Proceeds  from the sale of broadband  together with $350
million  financing to be provided by Goldman  Sachs will be used to de-lever the
company and restructure the bank credit facility.

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

                                       5

groups as well as banking  services  through its  banking/finance  segment.  The
company has $252  billion in assets  under  management  across a  wide-range  of
investment products and styles.  Finally,  the company operates in 51 offices in
28 countries,  and is focused on further expanding its international  investment
management  business,  particularly  as pension systems are reformed in numerous
countries around the world.

GENCORP INC. (GY) (SUB.  DEB. CV.,  5.75%,  04/15/07) has three main  divisions:
value-added systems for the aerospace and defense industries, integrated vehicle
sealing  systems  for  the  automotive  industry,  and  fine  chemicals  for the
pharmaceutical  industry.  GenCorp's  products  include  satellite  payloads and
ground systems, launch vehicle propulsion systems, and tactical weapons systems.
In 2002, the company earned $30 million on $1.1 billion of sales. GenCorp has an
equity market  capitalization  of $318 million and net debt of $352 million,  of
which the convertible  represents $150 million.  Last year the company generated
$110  million of EBITDA  (earnings  before  interest,  taxes,  depreciation  and
amortization)  and spent $45  million  on  capital  expenditures.  Liquidity  is
sufficient  with  interest  cover  of over  five  times.  The  company  also has
significant  real estate  holdings and recently  announced a joint  venture with
Panattoni to begin commercial development of some of these assets.

HILTON HOTELS CORP. (HLT) (SUB. DEB. CV., 5.00%,  05/15/06) is recognized as one
of the world's preeminent hospitality companies.  Hilton develops, owns, manages
and franchises hotels, resorts and vacation ownership properties. Hilton's hotel
system  includes  approximately  2,100  properties  totaling  over 337,000 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.

SEQUA CORP. (SQA'A) ($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  March  31,  2003,  305,200  shares  have been
repurchased in the open market under this stock  repurchase plan. Since the Fund
continues to trade at a premium to net asset  value,  we have been unable to buy
additional shares.

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 Convertible and Income  Securities Fund distributed
$0.20 per share on March 25, 2003. The next  distribution  is scheduled for June
2003.

                                       6

      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,  March,  June and September.  The Fund normally  distributes $0.20 per
share to common stock shareholders at quarter-end 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
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

      Convertible  securities  performed  well in the first quarter as investors
gravitated to less volatile income  generating  securities.  If the stock market
can make modest  progress and the corporate  bond market  remains  stable in the
year ahead, convertible securities should produce satisfactory returns.


                                           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
contact their broker to make this change.

  The number of shares of Common Stock  distributed to  participants in the 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.

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