TO OUR SHAREHOLDERS,

      As  hybrid  securities  with  equity  and  fixed  income  characteristics,
convertible security performance is impacted by stock and bond market trends. In
the second quarter of 2001, bonds were relatively flat.  Stocks rallied strongly
in April and early May, but gave  considerable  ground in June.  The Fund closed
the  quarter  with a  respectable  gain,  modestly  trailing  the  return on the
Standard & Poor's ("S&P") 500 Index.

INVESTMENT PERFORMANCE

      For the  second  quarter  ended June 30,  2001,  The  Gabelli  Convertible
Securities Fund's (the "Fund") net asset value ("NAV") total return was up 4.34%
after adjusting for the reinvestment of the $0.20 per share distribution paid on
June 25,  2001.  The S&P 500 Index and the Lipper  Convertible  Securities  Fund
Average rose 5.85% and 3.62%,  respectively,  over the same period.  The S&P 500
Index is an unmanaged  indicator of stock market  performance,  while the Lipper
Average  reflects the average  performance  of mutual funds  classified  in this
particular category.  The Fund rose 5.90% over the trailing  twelve-month period
after adjusting for the  reinvestment  of the $1.30 per share in  distributions.
The S&P 500 Index and Lipper Convertible Securities Fund Average declined 14.82%
and 10.65%, respectively, over the same twelve-month period.

      For the  two-year  period  ended June 30,  2001,  the Fund's  total return
averaged  3.72%  annually,   including  reinvestments  of  $2.33  per  share  in
distributions.  The S&P 500 Index  declined  4.42%  annually,  while the  Lipper
Convertible Securities Fund Average rose 6.76% annually,  over the same two-year
period.  For the five-year  period ended June 30, 2001,  the Fund's total return
averaged  8.35%  annually,  including  reinvestments  of  $5.105  per  share  in
distributions,  versus average annual total returns of 14.48% and 10.65% for the
S&P 500 Index and Lipper Convertible Securities Fund Average, respectively.

      Since  inception on July 3, 1989  through  June 30,  2001,  the Fund had a
cumulative total return of 192.86%,  including  adjustments of $11.366 per share
for distributions, which equates to an average annual total return of 9.37%.

      The Fund's common  shares ended the second  quarter at $10.75 per share on
the New York Stock  Exchange,  a premium  to the net asset  value of 3.37% and a
total  return of 7.43% for the second  quarter.  The Fund's  common  shares rose
25.30%  over  the  trailing   twelve-month   period  after   adjusting  for  all
distributions.

CORPORATE GOVERNANCE - GCV TRADING AT A PREMIUM!

      In past reports, we have outlined several management  initiatives that the
Board of  Directors  has taken to increase the Fund's  public  market price to 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. Additionally, when the Fund converted to closed-end
status in March 1995,  we expressed  our intent to have the Fund's common shares
track the Fund's net asset value.

      We are  happy to report to you that the  public  market  price is now at a
premium to the net asset  value.  As of the writing of this  shareholder  letter
(August 8, 2001),  the Fund's  shares were  trading at a premium of 3.65% to the
Fund's  net asset  value.  This is a  testament  to our  pro-active  shareholder
initiatives and the consistency of our performance over time.



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.

WHAT WE DO

      The success of momentum  investing in recent years and  investors'  desire
for instant  gratification have combined to make value investing appear dull. At
the risk of being dull, we will once again  describe the "boring" value approach
that has seen us through both good and bad markets over the last 12 years at the
Fund and for over 24 years at Gabelli Asset Management Company. In past reports,
we have tried to articulate  our  investment  philosophy  and  methodology.  The
following graphic further illustrates the interplay among the four components of
our valuation approach.

      Our  focus  is  on  free  cash  flow:  earnings  before  interest,  taxes,
depreciation and amortization minus the capital  expenditures  necessary to grow
the  business.  We believe  free cash flow is the best  barometer of a business'
value. Rising free cash flow often foreshadows net earnings improvement. We also
look at earnings per share  trends.  Unlike Wall  Street's  ubiquitous  earnings
momentum players,  we do not try to forecast earnings with accounting  precision
and then trade stocks based on quarterly  expectations and realities.  We simply
try to position ourselves in front of long-term earnings uptrends.  In addition,
we analyze on and off balance  sheet  assets and  liabilities  such as plant and
equipment,  inventories,  receivables,  and legal, environmental and health care
issues. We want to know everything and anything that will add to or detract from
our private market value estimates.

      Finally,  we look for a catalyst:  something  happening  in the  company's
industry or indigenous  to the company  itself that will surface  value.  In the
case of the independent  telephone stocks,  the catalyst is a regulatory change.
In the agricultural  equipment business,  it is the increasing world-wide demand
for  American  food and feed crops.  In other  instances,  it may be a change in
management,  sale or spin-off of a division or the  development  of a profitable
new business.

      Once we  identify  stocks  that  qualify  as  fundamental  and  conceptual
bargains,  we then become patient  investors.  This has been a proven  long-term
method for preserving and enhancing wealth in the U.S.  equities market.  At the
margin,  our new investments are focused on businesses that are well-managed and
will benefit from sustainable  long-term economic dynamics.  These include macro
trends,  such as the  globalization  of the market in filmed  entertainment  and
telecommunications, and micro trends, such as an increased focus on productivity
enhancing goods and services.

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

                                        3


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 4.4% during the second  quarter,  reflecting  the strength in the
U.S.  equity market.  This compared to a 5.9% rise in the S&P 500. Year to date,
convertibles  have demonstrated  their defensive  qualities by falling only 1.9%
versus a  decline  of 6.7% by the S&P 500.  The  average  convertible  now has a
conversion  premium  of 49% (up from 37% at the start of the year) and a current
yield of 3.8% (versus  4.5%).  The higher  conversion  premium and lower current
yield are partly due to the recent flood of zero-coupon  contingent deals coming
to the market. These transactions offer important tax and accounting benefits to
the  issuer,  but  appeal  primarily  to  non-taxable  investors.  Consequently,
zero-coupon convertibles have grown from 10% of the market at the end of 2000 to
over 30% currently.

      Since the beginning of the year, the domestic convertible market has grown
from $155 billion to $188  billion.  This growth has been the  consequence  of a
strong new issue calendar and lower redemption levels. New issuance is up 62% to
$57 billion  over the  comparable  period  last year,  which is just shy of last
year's total record of $60 billion.

      The best  performing  sector in the  convertible  market during the second
quarter was Healthcare (+13%),  while Utilities (-12%) was the worst performing.
Year to date,  the Consumer  Discretionary  (+19%) and Materials  (+18%) sectors
standout as winners while  Telecommunications  (-12%) was a laggard.  Meanwhile,
during the quarter, speculative grade convertibles outperformed investment grade
issues  (+4.8%  versus  +2.4%),   which  were  less  equity   sensitive;   small
capitalization  companies beat large  capitalization names (+5.7% versus +4.7%);
and growth bested value (+6.9% versus  +1.0%).  Finally,  balanced  convertibles
were the best performing during the quarter (+7.2%), but busted convertibles are
leading the way year to date (+9.3%).

COMMENTARY

A TUG OF WAR

      As evidenced by a record number of  pre-announced  earnings  shortfalls in
the second quarter,  six Federal  Reserve Board ("Fed")  interest rate cuts this
year  totaling  275 basis  points  (2.75%)  have yet to revive the sagging  U.S.
economy.  This should not come as a surprise. It takes time for Fed rate cuts to
work their magic, but the rabbit eventually  emerges from the hat. The $300-$600
federal income tax rebate many  Americans will be receiving in  August/September
should provide a modest boost for the economy.  Granted,  higher utilities bills
and expensive gasoline will soak up some of this cash.  However,  the tax rebate
should put consumers in a better mood and provide part of the underpinning for a
consumer led economic recovery beginning in the fourth quarter.  We also believe
inventory  in all but  telecommunications/technology  will have  largely  worked
through the system at that point.  Energy prices have abated  providing  further
relief.

      When will the stock market begin anticipating an economic  recovery?  In a
sense, it already has. The  April/early-May  rally  demonstrated  that investors
were  at  least  temporarily  willing  to look  past  poor  short-term  earnings
prospects and forward to better times in 2002.  Unfortunately,  when  confronted
with second quarter  earnings  "confessions"  and warnings that profits were not
likely to improve in the third quarter,  investors abandoned the "long view" and
once again focused on the short-term earnings negatives. We may see this pattern
hold for the balance of

                                        4


the year, as market  rallies are cut short by bad earnings news. So, we think it
will be difficult for the broad market indices to make much progress this year.

      Intermediate  term bonds were flat in the second  quarter,  but long bonds
retreated,  signally the market's  concern that aggressive Fed easing may create
inflationary pressure over the longer term. With the Fed reducing interest rates
by 25 rather than 50 basis  points at its late June  meeting,  the longer end of
the bond market may firm.

INVESTMENT SCORECARD

      This  quarter's  winners  came  from a wide  variety  of  industry  groups
including broadcasting (Granite  Broadcasting),  bananas (Chiquita),  industrial
cyclicals (WHX Corp.), and utilities (Northeast  Utilities).  Telecommunications
companies  dominated  our laggard's  list,  with Rogers  Communications,  United
States Cellular, and Nextel Communications retreating.

GOOD THINGS COME TO THOSE WHO WAIT

      The  critical  element  to our  success  in  the  equity  and  convertible
securities  markets  has been  patience  in both the  selection  process  and in
waiting for the values of portfolio positions to be recognized. We will continue
to be patient and  opportunistic  in  selecting  converts  for the Fund and will
invest in  short-term  instruments  (including  time  sensitive  workouts)  when
appropriate.  We purchased mostly  short-term U.S.  Treasury  obligations in the
past. However,  the U.S. financial system has improved  significantly and we now
take advantage of other  short-term  alternatives.  In this regard,  the Fund at
times engages in risk arbitrage to generate  returns.  By risk arbitrage we mean
investing in "event"  driven  situations;  primarily,  but not  exclusively,  in
announced   mergers,   acquisitions,   reorganizations   and   other   "workout"
opportunities. In order to avoid overall market risk in these opportunities, the
Fund will concentrate on lower risk transactions.

      Simply  stated,  risk  arbitrage is  investing in a merger or  acquisition
target after the deal has been  announced and  pocketing the spread  between the
trading  price of the target  company  following the  announcement  and the deal
price  upon  closing.  This  spread is  usually  relatively  narrow,  offering a
somewhat  modest nominal total return.  However,  since deals generally close in
much less than a year's time,  this modest total return  translates  into a much
more attractive annualized return.

      We borrow a quote from  Warren  Buffett to explain our  occasional  use of
risk arbitrage in the Fund: "Our  subsidiaries  sometimes engage in arbitrage as
an alternative to holding short-term cash equivalents.  We prefer, of course, to
make major long-term  commitments.  But we often have more cash than good ideas.
At such times  arbitrage  sometimes  promises much greater returns than Treasury
Bills and,  equally  important,  cools any  temptation  we may have to relax our
standards for long-term investments."

      In short,  the high cash  position in the Fund does not reflect any effort
on  our  part  to  time  the  convertible  securities  market.  It is  rather  a
consequence of our  value-oriented  discipline.  At the same time, a sampling of
our  convertible  securities  has been  called  by their  issuers  and we either
received cash or stock. Our portfolio  turnover rate reflects this activity,  as
well as our  investments  in "event"  driven  situations  that were  consummated
during  the  year.  We are  always  hard at work  evaluating  opportunities  and
identifying  fundamental  bargains to progress to a more fully invested posture.
However,  we will not stretch our fundamental  parameters and introduce  greater
market risk to the portfolio.

LET'S TALK CONVERTS

      The following are  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.

CITIZENS  COMMUNICATIONS  CO. (5.00% CV.  PFD.),  will soon become the country's
largest  independent  local  exchange  carrier with about 3 million access lines
once it completes several acquisitions of over 2 million lines for $6.5 billion.
Upon  completion  of these  transactions,  accompanied  by  divestitures  of its
utilities   operations,   the  company   will   reposition   itself  as  a  pure
telecommunications  company.  Citizens also owns 81% of a  competitive  carrier,
Electric  Lightwave (ELIX - $1.31 - Nasdaq),  with fiber optic networks covering
the Western part of the U.S.

HILTON HOTELS CORP. (HLT) (SUB. DEB. CV., 5.00%, 05/15/06), begun in 1919, owns,
manages,  and/or  franchises  nearly 1,800 hotels with 300,000 rooms  worldwide.
Hilton's  portfolio of brands, in addition to Hilton,  now includes Hampton Inn,
DoubleTree,  Embassy  Suites,  Homewood  Suites,  Red Lion Hotels and Inns,  and
Conrad International. The Company serves a variety of markets ranging from first
class luxury  hotels and resorts to  value-oriented  lodgings,  kitchen-equipped
suites,  and vacation  timeshare units.  Well-known hotel properties include The
Waldorf-Astoria in New York and Chicago's Palmer House Hilton.

KAMAN CORP. (SUB. DEB. CV., 6.00%,  03/15/12),  founded in 1945, is a pioneer in
the  helicopter  industry.  Aircraft  manufacturing  remains  the  core  of  the
business. Kaman serves both commercial and governmental markets with helicopters
and aircraft components. The company also produces specialized, high-value niche
market  products and  services  that tend to be  technological  leaders in their
markets.  Kaman is a major,  national distributor of original equipment,  repair
and  replacement  products  and  value-added  services to nearly every sector of
North American industry.  The company also manufactures and distributes  musical
instruments (Ovation guitars) and accessories to independent retailers.

ROBBINS & MYERS INC.  (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, and food and
beverage.  The Energy Systems  business,  with a $12 million  backlog along with
higher  sustained  crude oil and  natural  gas  prices  and  increased  drilling
activity, should remain strong through the balance of fiscal 2001. We think that
revenues in the Process  Systems segment will be down in 2001 due to weakness in
end  markets,  but with a backlog of almost  $86  million,  the  segment is well
positioned for the future. The company will continue to use its strong cash flow
to make acquisitions and develop new products enhancing its growth prospects.

SEALED  AIR  CORP.  ($2.00  CV.  PFD.,  SER.  A) is a  global  manufacturer  and
distributor of a wide range of protective and specialty  packaging materials and
systems  for  industrial,  food  and  consumer  products.  The  company  is well
positioned to benefit from case-ready packaging and electronic commerce.  Sealed
Air is a strong  free  cash flow  generator.  Such cash flow will be used to pay
down debt, make niche acquisitions and buy back stock.

SEQUA  CORP.  ($5.00 CV.  PFD.) is a  diversified  company  with  businesses  in
aerospace,   pre-paint  metal,  specialty  chemical  and  printing  and  cannery
equipment.  Chromalloy Gas Turbine,  Sequa's aerospace business,  is the largest
independent  supplier of overhaul and repair to 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

                                        6


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.,   4.00%,   02/01/02),
headquartered  in Long Island City, New York,  supplies  functional  replacement

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.

1998, and is now the largest solid waste company in North  America.  The company
provides a number of services,  including collection,  transfer,  landfill,  and

IN CONCLUSION

      A strong,  albeit short-lived,  stock market rally along with a relatively
stable bond market helped convertible securities generate respectable returns in
the second  quarter of 2001.  Looking ahead over the next several  quarters,  we
believe convertible  security yields will help support prices as stocks struggle
to reconcile good news (Fed rate

                                        8


cuts) with bad news  (generally  lousy  earnings).  When the stock market begins
recovering in 2002, convertibles should participate.

                               Sincerely,
                               /S/ MARIO J. GABELLI
                               MARIO J. GABELLI, CFA

                  THE GABELLI CONVERTIBLE SECURITIES FUND, INC.
                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1. ORGANIZATION. The Gabelli Convertible Securities Fund, Inc. (the "Fund") is a
closed-end  diversified  management  investment  company  registered  under  the
Investment  Company Act of 1940, as amended (the "1940 Act"),  whose  investment
objective  is to seek a high  level of total  return  through a  combination  of
current income and capital appreciation by investing in convertible  securities.
The Fund was  incorporated  in  Maryland  on  December  19,  1988 as an open-end
diversified management investment company and commenced investment operations on
July 3, 1989.  The Board of  Directors,  upon  approval at a special  meeting of
shareholders  held on February 17, 1995,  voted to approve the conversion of the
Fund to closed-end status, effective March 31, 1995.

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. If there were no asked prices quoted
on that day,  then the  security is valued at the  closing bid price.  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 Bank of
New York,  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.

                                       15


                  THE GABELLI CONVERTIBLE SECURITIES FUND, INC.
              NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)

If the seller defaults and the value of the collateral declines or if bankruptcy
proceedings   are  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. Such investments will only be
made if they are economically  appropriate to the reduction of risks involved in
the management of the Fund's investments. 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
appreciation/depreciation   on  investments  and  futures  contracts.  The  Fund
recognizes  a realized  gain or loss when the  contract  is closed.  At June 30,
2001, 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.

      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.  At June 30, 2001,  the Fund held no forward
foreign exchange contracts.

      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.

     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

                                       16


                  THE GABELLI CONVERTIBLE SECURITIES FUND, INC.
              NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)

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 as of 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. 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.  Distributions to shareholders of the Fund's
8.00% Cumulative Preferred Stock ("Cumulative Preferred Stock") are accrued on a
daily basis and are determined as described in Note 5.

      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.

3. AGREEMENTS AND  TRANSACTIONS  WITH  AFFILIATES.  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,  equal on an annual  basis to 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 and oversees
the  administration  of all  aspects of the Fund's  business  and  affairs.  The
Adviser  has  agreed to reduce  the  management  fee on the  incremental  assets
attributable  to the Cumulative  Preferred  Stock if the total return of the net
asset  value of the  common  shares of the  Fund,  including  distributions  and
advisory fee subject to reduction,  does not exceed the stated  dividend rate of
the  Cumulative  Preferred  Stock.  For the six months ended June 30, 2001,  the
Fund's total  return on the net asset value of the common  shares did not exceed
the  stated  dividend  rate  of  the  Cumulative  Preferred  Stock.  Thus,  such
management fees were not earned on the incremental assets.

      During the six months ended June 30, 2001, Gabelli & Company, Inc. and its
affiliates  received  $25,424 in brokerage  commissions as a result of executing
agency transactions in portfolio securities on behalf of the Fund.

4.  PORTFOLIO  SECURITIES.  Costs  of  purchases  and  proceeds  from  sales  of
securities,  other than short-term securities, for the six months ended June 30,
2001 aggregated $29,156,599 and $30,813,961, respectively.

5. CAPITAL.  The Articles of Incorporation,  dated December 19, 1988, permit the
Fund to issue 100,000,000 shares of common stock (par value $0.001).

      Transactions in capital stock were as follows:

      In addition,  the Fund has been authorized to issue up to 2,000,000 shares
of Preferred Stock of which  1,200,000  shares has been designated as $0.001 par
value 8%  Cumulative  Preferred  Stock.  Dividends  on shares of the  Cumulative
Preferred  Stock are  cumulative.  The Fund is  required to meet  certain  asset
coverage tests with respect to the Cumulative Preferred Stock. If the Fund fails
to meet these  requirements  and does not correct such failure,  the Fund may be
required to redeem,  in part or in full,  the  Cumulative  Preferred  Stock at a
redemption price of $25.00 per share plus an amount equal to the accumulated and
unpaid  dividends  whether or not declared on such shares in order to meet these
requirements.  Additionally,  failure to meet the  foregoing  asset  requirement
could  restrict the Fund's ability to pay dividends to Common  Shareholders  and
could lead to sales of portfolio  securities at inopportune times. The Preferred
Stock is  callable at the  redemption  price at the option of the Fund after May
15, 2002. This Cumulative  Preferred Stock introduced  leverage into the capital
structure  of the  Fund.  This  leverage  tends to  magnify  both the  risks and
opportunities to Common Shareholders.  At June 30, 2001, the 1,200,000 shares of
8% Cumulative  Preferred Stock  outstanding  accrued  dividends in the amount of
$46,667. The income received on the Fund's assets may vary in a manner unrelated
to the fixed rate, which could have either a beneficial or detrimental impact on
net investment income and gains available to Common Shareholders.

      The Fund  shall not  declare  dividends  or make  other  distributions  on
1,200,000  shares of Common  Stock or purchase any such shares if at the time of
the  declaration,  distribution or purchase,  asset coverage with respect to the
outstanding Preferred Stock would be less than 200%.

      The holders of Cumulative Preferred Stock have voting rights equivalent to
those of the holders of Common Stock (one vote per share) and will vote together
with holders of shares of Common Stock as a single class. In addition,  the 1940
Act  requires  that  along with  approval  of the  holders of a majority  of the
holders  of  Common  Stock,  approval  of a  majority  of  the  holders  of  any
outstanding shares of Cumulative  Preferred Stock, voting separately as a class,
would be required to (a) adopt any plan of  reorganization  that would adversely
affect the Cumulative  Preferred Stock, and (b) take any action requiring a vote
of  security  holders,  including,  among  other  things,  changes in the Fund's
subclassification  as  a  closed-end   investment  company  or  changes  in  its
fundamental investment restrictions.

      The Adviser has been  authorized to repurchase on behalf of the Fund up to
500,000  shares of Common  Stock of the Fund in the open  market,  whenever  the
shares are  trading at a discount of 10% or more from the net asset value of the
shares.  For the six months ended June 30, 2001, the Fund did not repurchase any
shares of  Common  Stock.  All  shares of  Common  Stock  repurchased  have been
retired.

                         AUTOMATIC DIVIDEND REINVESTMENT
                        AND VOLUNTARY CASH PURCHASE PLAN

ENROLLMENT IN THE PLAN

   It  is  the  Policy  of  The  Gabelli   Convertible   Securities  Fund,  Inc.
("Convertible  Securities  Fund")  to  automatically  reinvest  dividends.  As a
"registered"   shareholder  you  automatically   become  a  participant  in  the
Convertible Securities Fund's Automatic Dividend Reinvestment Plan (the "Plan").
The  Plan  authorizes  the  Convertible  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  Securities  Fund.  Plan  participants  may  send  their  stock
certificates to State Street Bank and Trust Company ("State  Street") 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 Securities Fund, Inc.
                     c/o State Street Bank and Trust Company
                                  P.O. Box 8200
                              Boston, MA 02266-8200

   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 or requesting a copy of the terms of the
Plan may contact State Street at 1 (800) 336-6983.

   SHAREHOLDERS WISHING TO LIQUIDATE REINVESTED SHARES held at State Street Bank
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  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 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
Securities  Fund valued at market  price.  If the  Convertible  Securities  Fund
should  declare a dividend or capital gains  distribution  payable only in cash,
State Street will buy Common Stock in the open market,  or on the New York Stock
Exchange or elsewhere, for the participants' accounts,  except that State Street
will  endeavor  to  terminate  purchases  in  the  open  market  and  cause  the
Convertible 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  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 State Street 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  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 State Street Bank and Trust Company for investments
in the  Convertible  Securities  Fund shares at the then current  market  price.
Shareholders  may send an amount  from $250 to  $10,000.  State  Street Bank and
Trust  Company will use these funds to purchase  shares in the open market on or
about the 1st and 15th of each month.  State Street Bank and Trust  Company 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 State Street Bank and Trust Company, P.O.
Box 8200,  Boston,  MA 02266-8200  such that State Street 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 State Street Bank and Trust  Company 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 Securities Fund.
