  (a) Returns  represent past  performance and do not guarantee  future results.
      Total returns and average  annual returns  reflect  changes in share price
      and reinvestment of dividends and are net of expenses.  Investment returns
      and the principal value of an investment  will fluctuate.  When shares are
      redeemed, they may be worth more or less than their original cost. The Dow
      Jones  Industrial  Average is an  unmanaged  index of 30 large  industrial
      stocks.  The S&P 500 Index and the Nasdaq  Composite  Index are  unmanaged
      indicators  of  stock  market   performance.   Dividends  are   considered
      reinvested  (except  for the  Nasdaq  Composite  Index).  Performance  for
      periods less than one year is not annualized.  Current  performance may be
      lower or higher than the performance data presented. Visit www.gabelli.com
      for  performance  information as of the most recent  month-end.  Investors
      should consider the investment objectives,  risks and charges and expenses
      of the Fund  before  investing.  The  prospectus  contains  more  complete
      information  about this and other  matters  and  should be read  carefully
      before  investing.  The Class AAA  Shares'  net asset  values  are used to
      calculate  performance  for the periods  prior to the  issuance of Class A
      Shares, Class B Shares and Class C Shares on December 31, 2003. The actual
      performance  for the Class B and Class C Shares  would have been lower due
      to the additional expenses associated with these classes of shares.
  (b) Performance is calculated  from  inception of Class AAA Shares on March 3,
      1986.
  (c) Includes the effect of the maximum 5.75% sales charge at the  beginning of
      the period.
  (d) Includes the effect of the applicable  contingent deferred sales charge at
      the end of the period shown for Class B and Class C Shares, respectively.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------
1.  ORGANIZATION.  The Gabelli Asset Fund (the "Fund") was organized on November
25, 1985 as a Massachusetts business trust. The Fund is a diversified,  open-end
management  investment  company  registered under the Investment  Company Act of
1940,  as amended (the "1940 Act").  The Fund's  primary  objective is growth of
capital. The Fund commenced investment operations on March 3, 1986.

2. SIGNIFICANT  ACCOUNTING POLICIES.  The preparation of financial statements in
accordance  with  U.S.  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 or traded in the U.S. over-the-counter market for
which market quotations are readily available are valued at the last quoted sale
price or a market's  official  closing  price 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. If no bid or asked  prices are quoted on such
day,  the  security is valued at the most  recently  available  price or, if the
Board of Trustees (the "Board") so determines, by such other method as the Board
shall


                                        9


THE GABELLI ASSET FUND
NOTES TO FINANCIAL STATEMENTS (CONTINUED)(UNAUDITED)
- --------------------------------------------------------------------------------
determine in good faith, to reflect its fair market value.  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").

Portfolio securities primarily traded on foreign markets are generally valued at
the preceding closing values of such securities on their respective exchanges or
if after the close,  market  conditions  change  significantly,  certain foreign
securities may be fair valued  pursuant to procedures  established by the Board.
Debt  instruments  that are not credit impaired with remaining  maturities of 60
days or less are valued at amortized cost, unless the Board determines such does
not reflect the securities'  fair value, in which case these  securities will be
valued at their fair value as determined by the Board. Debt instruments having a
maturity greater than 60 days for which 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 such day,  the security is valued using the closing bid
price.  Futures contracts are valued at the official closing settlement price of
the exchange or board of trade on which the applicable contract is traded.

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.  Fair valuation
methodologies  and procedures may include,  but are not limited to: analysis and
review of available  financial and non-financial  information about the company;
comparisons  to the  valuation  and changes in valuation of similar  securities,
including a comparison of foreign securities to the equivalent U.S. dollar value
ADR  securities at the close of the U.S.  exchange;  and evaluation of any other
information that could be indicative of the value of the security.

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, 2004, there were no open forward foreign
exchange contracts.

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

THE GABELLI ASSET FUND

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

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

DIVIDENDS AND  DISTRIBUTIONS  TO  SHAREHOLDERS.  Dividends and  distributions to
shareholders  are recorded on the ex-dividend  date.  Income  distributions  and
capital gain  distributions are determined in accordance with Federal income tax
regulations which may differ from accounting  principles  generally  accepted in
the United States.  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.

For the year ended  December 31, 2003,  reclassifications  were made to decrease
accumulated  net investment  income for $62,684 and to decrease  accumulated net
realized loss on investments and foreign currency transactions for $62,684.

The tax character of  distributions  paid during the fiscal year ended  December
31, 2003 was as follows:

                                                      ===========

EXPENSES. Certain administrative expenses are common to, and allocated among the
Classes of Shares.  Such allocations are made on the basis of average net assets
or other criteria  directly  affecting the expenses as determined by the Adviser
pursuant to procedures established by the Board.

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  (the  "Code").  It is the Fund's  policy to comply  with the
requirements  of the Code  applicable to regulated  investment  companies and to
distribute  substantially  all of its net investment  company taxable income and
net capital gains. Therefore, no provision for Federal income taxes is required.

Dividends and interest from non-U.S.  sources received by the Fund are generally
subject  to  non-U.S.  withholding  taxes  at  rates  ranging  up to  30%.  Such
withholding  taxes may be reduced or  eliminated  under the terms of  applicable
U.S. income tax treaties, and the Fund intends to undertake any procedural steps
required to claim the benefits of such treaties.

9. OTHER MATTERS.  On October 7, 2003,  the Fund's  Adviser  received a subpoena
from the Attorney  General of the State of New York  requesting  information  on
mutual fund shares trading practices. The Adviser has also received requests for
information from the SEC regarding  mutual fund trading  practices and valuation
of portfolio  securities.  The Adviser has responded to the  requests.  The Fund
does not believe that these matters will have a material  adverse  effect on the
Fund's financial position or the results of its operations.

10.  INDEMNIFICATIONS.  The Fund enters into contracts that contain a variety of
indemnifications. The  Fund's  maximum  exposure  under  these  arrangements  is
unknown.  However, the Fund has not had prior claims or losses pursuant to these
contracts and expects the risk of loss to be remote.

ITEM 9.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

The  Board  of  Trustees   has  a  Nominating   Committee   comprised  of  three
"non-interested" (as such term is defined by the Investment Company Act of 1940,
as  amended)  Trustees,  namely  Anthony  J.  Colavita,  Werner J.  Roeder,  and
Salvatore J. Zizza.  The  Nominating  Committee is responsible  for  identifying
individuals believed to be qualified to become Board members in the event that a
position is vacated or created.  The Nominating Committee will consider Trustees
candidates  recommended by shareholders.  In considering candidates submitted by
shareholders, the Nominating Committee will take into consideration the needs of
the Board of Trustees,  the qualifications of the candidate and the interests of
shareholders.  The  Nominating  Committee may also take into  consideration  the
number of shares  held by the  recommending  shareholder  and the length of time
that  such  shares  have  been  held.  To  have a  candidate  considered  by the
Nominating  Committee,  a shareholder must submit the  recommendation in writing
and must include the following information:

     o    The name of the shareholder and evidence of the person's  ownership of
          shares  of the Fund,  including  the  number  of shares  owned and the
          length of time of ownership;

     o    The name of the candidate,  the candidate's resume or a listing of his
          or her  qualifications  to be a Trustee  of the Fund and the  person's
          consent  to be  named  as a  Trustee  if  selected  by the  Nominating
          Committee and nominated by the Board of Trustees; and

     o    If  requested  by the  Nominating  Committee,  a completed  and signed
          directors questionnaire.

The shareholder  recommendation and information  described above must be sent to
the Fund's Secretary c/o Gabelli Funds, LLC, James E. McKee and must be received
by the  Secretary  no less than 120 days  prior to the  anniversary  date of the
Fund's most recent annual meeting of  shareholders  or, if the meeting has moved
by more than 30 days, a reasonable amount of time before the meeting.

The Nominating Committee believes that the minimum qualifications for serving as
a  Trustee  of the  Fund are that the  individual  demonstrate,  by  significant
accomplishment in his or her field, an ability to make a meaningful contribution
to the Board of Trustees'  oversight of the business and affairs of the Fund and
have an impeccable  record and reputation for honest and ethical conduct in both
his or her professional  and personal  activities.  In addition,  the Nominating
Committee  examines  a  candidate's   specific   experiences  and  skills,  time
availability in light of other commitments,  potential conflicts of interest and
independence  from management and the Fund. The Nominating  Committee also seeks
to have  the  Board  of  Trustees  represent  a  diversity  of  backgrounds  and
experience.





ITEM 10. CONTROLS AND PROCEDURES.

     (a) The registrant's  principal executive and principal financial officers,
         or  persons  performing  similar  functions,  have  concluded  that the
         registrant's  disclosure  controls and  procedures  (as defined in Rule
         30a-3(c)  under the  Investment  Company Act of 1940,  as amended  (the
         "1940 Act") (17 CFR 270.30a-3(c)))  are effective,  as of a date within
         90 days of the filing date of the report that  includes the  disclosure
         required by this paragraph, based on their evaluation of these controls
         and  procedures  required by Rule  30a-3(b)  under the 1940 Act (17 CFR
         270.30a-3(b))  and Rules  13a-15(b) or 15d-15(b)  under the  Securities
         Exchange   Act  of  1934,   as  amended   (17  CFR   240.13a-15(b)   or
         240.15d-15(b)).


     (b) There  were  no  changes  in the  registrant's  internal  control  over
         financial reporting (as defined in Rule 30a-3(d) under the 1940 Act (17
         CFR  270.30a-3(d))  that occurred during the  registrant's  last fiscal
         half-year (the  registrant's  second fiscal half-year in the case of an
         annual report) that has materially affected, or is reasonably likely to

         reporting.
