THE GABELLI GROWTH FUND
DISCLOSURE OF FUND EXPENSES (UNAUDITED)
For the Six Month Period from January 1, 2005 through June 30, 2005
                                                                   EXPENSE TABLE
- --------------------------------------------------------------------------------
We believe it is important for you to understand the impact of fees and expenses
regarding  your  investment.  All mutual  funds have  operating  expenses.  As a
shareholder  of a fund,  you  incur  ongoing  costs,  which  include  costs  for
portfolio  management,  administrative  services,  and shareholder reports (like
this one), among others.  Operating  expenses,  which are deducted from a fund's
gross income,  directly  reduce the investment  return of a fund.  When a fund's
expenses are expressed as a percentage of its average net assets, this figure is
known as the expense  ratio.  The  following  examples  are intended to help you
understand  the  ongoing  costs (in  dollars) of  investing  in your Fund and to
compare these costs with those of other mutual funds.  The examples are based on
an  investment  of $1,000 made at the beginning of the period shown and held for
the entire period.

The Expense Table below illustrates your Fund's costs in two ways:

ACTUAL FUND  RETURN:  This section  provides  information  about actual  account
values and actual expenses. You may use this section to help you to estimate the
actual  expenses that you paid over the period after any fee waivers and expense
reimbursements.  The "Ending  Account  Value"  shown is derived  from the Fund's
ACTUAL return during the past six months,  and the "Expenses Paid During Period"
shows the dollar  amount  that would have been paid by an  investor  who started
with $1,000 in the Fund. You may use this information,  together with the amount
you invested, to estimate the expenses that you paid over the period.

To do so, simply  divide your account  value by $1,000 (for  example,  an $8,600
account value  divided by $1,000 = 8.6),  then multiply the result by the number
given for your Fund under the heading  "Expenses Paid During Period" to estimate
the expenses you paid during this period.

HYPOTHETICAL 5% RETURN:  This section provides  information  about  hypothetical
account  values and  hypothetical  expenses  based on the Fund's actual  expense
ratio. It assumes a hypothetical  annualized return of 5% before expenses during
the period shown.  In this case -- because the  hypothetical  return used is NOT
the Fund's actual return -- the results do not apply to your  investment and you
cannot use the  hypothetical  account  value and expense to estimate  the actual
ending  account  balance or expenses  you paid for the period.  This  example is
useful in making  comparisons  of the ongoing costs of investing in the Fund and
other  funds.  To do so,  compare  this  5%  hypothetical  example  with  the 5%
hypothetical examples that appear in shareholder reports of other funds.

Please note that the  expenses  shown in the table are meant to  highlight  your
ongoing  costs only and do not  reflect  any  transactional  costs such as sales
charges (loads),  redemption fees, or exchange fees, if any, which are described
in the Prospectus. If these costs were applied to your account, your costs would
be higher.  Therefore, the 5% hypothetical return is useful in comparing ongoing
costs only,  and will not help you determine the relative  total costs of owning
different funds. The "Annualized  Expense Ratio"  represents the actual expenses
for the last six  months  and may be  different  from the  expense  ratio in the
Financial Highlights which is for the six months ended June 30, 2005.

     by the number of days in the most recent fiscal half-year,  then divided by
     365.

THE GABELLI GROWTH FUND
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------


1.  ORGANIZATION.  The Gabelli Growth Fund (the "Fund") was organized on October
24, 1986 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 capital
appreciation. The Fund commenced investment operations on April 10, 1987.

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  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 of the foreign markets, but prior to the close of business on
the day the securities are being valued, 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
amount  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  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.

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.

DETERMINATION   OF  NET  ASSET  VALUE  AND  CALCULATION  OF  EXPENSES.   Certain
administrative  expenses are common to, and allocated among,  various affiliated
funds.  Such allocations are made on the basis of each Fund's average net assets
or other criteria  directly  affecting the expenses as determined by the Adviser
pursuant to procedures established by the Board.

In  calculating  net asset  value per share of each  class,  investment  income,
realized and  unrealized  gains and losses,  redemption  fees and expenses other
than class specific expenses,  are allocated daily to each class of shares based
upon the  proportion  of net assets of each class at the  beginning of each day.
Distribution expenses are solely borne by the class incurring the expense.

DIVIDENDS AND  DISTRIBUTIONS  TO  SHAREHOLDERS.  Dividends and  distributions to
shareholders are recorded on the ex-dividend date. Distributions to shareholders
are based on  ordinary  income and  long-term  capital  gains as  determined  in
accordance with Federal income tax regulations, which may differ from income and
capital gains as determined under U.S. 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 characterizations of distributions made by the Fund.

For the year ended  December 31, 2004,  reclassifications  were made to increase
accumulated net investment income by $7,501,356,  with an offsetting  adjustment
to additional paid-in capital.

No distributions were made during the year ended December 31, 2004.

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 policy of the Fund 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.

At December 31, 2004, the difference between book basis and tax basis unrealized
appreciation  was  attributable  primarily to the tax deferral of losses on wash
sales.

As of December 31, 2004, the components of  accumulated  earnings/(losses)  on a
tax basis were as follows:

       Accumulated capital loss carryforward ................  $(1,163,304,151)
       Net unrealized appreciation ..........................      146,644,157

At December 31, 2004,  the Fund has net capital loss  carryforwards  for Federal
income tax purposes of  $1,163,304,151,  which are  available  to reduce  future
required distributions of net capital gains to shareholders.  $68,961,980 of the
loss carryforward is available  through 2009;  $743,150,002 is available through
2010;  $350,050,494  is available  through  2011;  and  $1,141,675  is available
through 2012.

The following  summarizes  the tax cost of  investments  and related  unrealized
appreciation/depreciation at June 30, 2005:

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

5. PORTFOLIO SECURITIES. Purchases and proceeds from the sales of securities for

NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)
- --------------------------------------------------------------------------------


The cost of  calculating  the Fund's net asset value per share is a Fund expense
pursuant to the Advisory Agreement between the Fund and the Adviser.  During the
six months  ended June 30,  2005,  the Fund  reimbursed  the Adviser  $22,500 in
connection  with the cost of  computing  the  Fund's net asset  value,  which is
included in miscellaneous expenses in the Statement of Operations.

7. LINE OF CREDIT.  The Fund has access to an unsecured  line of credit of up to
$25,000,000  from the  custodian for temporary  borrowing  purposes.  Borrowings
under this  arrangement  bear  interest at 0.75% above the Federal Funds rate on
outstanding  balances.  During the six months  ended June 30, 2005 there were no
borrowings from the line of credit.

8. SHARES OF  BENEFICIAL  INTEREST.  The Fund  offers four  classes of shares --
Class AAA Shares,  Class A Shares,  Class B Shares and Class C Shares. Class AAA
Shares are offered only to investors  who acquire them  directly  from Gabelli &
Company or  through  selected  broker/dealers  without a sales  charge.  Class A
Shares are subject to a maximum front-end sales charge of 5.75%.  Class B Shares
are subject to a contingent  deferred  sales  charge  ("CDSC")  upon  redemption
within six years of purchase and  automatically  convert to Class A Shares after
eight  years  of the  original  purchase.  The  applicable  CDSC is  equal  to a
declining  percentage of the lesser of the net asset value per share at the date
of the original  purchase or at the date of  redemption,  based on the length of
time held.  Class C Shares are subject to a 1% CDSC for one year after purchase.
As of July 27, 2004, Class B Shares are available only through exchange of Class
B Shares of other Funds distributed by Gabelli & Company. The Board has approved
Class I Shares which have not been offered publicly.

Effective June 15, 2005, the Fund imposed a redemption fee of 2.00% on Class AAA
Shares,  Class A Shares,  Class B Shares and Class C Shares that are redeemed or
exchanged  on or before the seventh day after the date of a purchase.  (Prior to
June 15, 2005, the Fund imposed a redemption fee on shares that were redeemed or
exchanged  within the sixtieth day after the date of a purchase.) The redemption
fee  is  deducted  from  the  proceeds   otherwise   payable  to  the  redeeming
shareholders  and is retained by the Fund. The  redemption  fees retained by the
Fund during the six months ended June 30, 2005 amounted to $21,407.

The redemption fee does not apply to shares purchased  through programs that the
Adviser  determined to have  appropriate  short-term  trading policies in place.
Additionally,  certain recordkeepers for qualified and non-qualified  retirement
plans that could not collect the redemption fee at the participant  level due to
systems limitations have received an extension to implement such systems.

9. OTHER MATTERS. The Adviser and/or affiliates have received subpoenas from the
Attorney General of the State of New York and the SEC requesting  information on
mutual fund  shares  trading  practices.  Gabelli  Asset  Management  Inc.,  the
Adviser's  parent  company,  is responding  to these  requests for documents and
testimony.  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.

                             THE GABELLI GROWTH FUND

     BOARD CONSIDERATION AND RE-APPROVAL OF MANAGEMENT AGREEMENT (UNAUDITED)

At its meeting on February  16,  2005,  the Board of Trustees  ("Board")  of the
Trust approved the  continuation of the investment  advisory  agreement with the
Adviser for the Trust on the basis of the  recommendation  by the trustees  (the
"independent  trustees")  who are not  "interested  persons"  of the Trust.  The
following  paragraphs  summarize the material information and factors considered
by the  independent  trustees  as well as  their  conclusions  relative  to such
factors.

NATURE,  EXTENT AND QUALITY OF SERVICES.  The  independent  trustees  considered
information  regarding  the  portfolio  manager,  the depth of the analyst  pool
available to the Adviser and the portfolio manager, the scope of administrative,
shareholder  and other  services  supervised  or provided by the Adviser and the
absence of significant  service problems  reported to the Board. The independent
trustees noted the experience, length of service and reputation of the portfolio
manager.

INVESTMENT PERFORMANCE.  The independent trustees reviewed the short, medium and
long-term  performance  of the Trust  against a peer group of  large-cap  growth
funds.  The trustees noted that the Trust's  performance was near the top 25% of
the funds in its  category for the prior ten years but was in or near the lowest
25% of the funds in its category for shorter one, three,  and five year periods.
The  trustees  also  noted  that  relative  performance  had  shown  substantial
improvement in recent months.

PROFITABILITY.  The  independent  trustees  reviewed  summary data regarding the
profitability of the Trust to the Adviser both with an  administrative  overhead
charge and without  such a charge.  The trustees  also noted that the  Adviser's
affiliated  broker  received  distribution  fees  and  minor  amounts  of  sales
commissions  and that the  Adviser  received  a  moderate  level of soft  dollar
research benefits through the Trust's portfolio  brokerage.

ECONOMIES OF SCALE. The independent trustees discussed the major elements of the
Adviser's  cost  structure and the  relationship  of those elements to potential
economies of scale.  The  independent  trustees  agreed that the Adviser  should
gather and provide them with  information  regarding  possible ways of measuring
potential  economies of scale so that they would be in a position to review this
potential  issue  in  greater  detail  if the  Trust  grew  substantially  on an
inflation adjusted basis beyond its previous largest aggregate asset value.

SHARING  OF  ECONOMIES  OF  SCALE.  The  independent  trustees  noted  that  the
investment  management fee schedule for the Trust does not take into account any
potential  economies  of scale  that may  develop  or any  losses or  diminished
profitability to the Adviser in prior years.

SERVICE AND COST  COMPARISONS.  The  independent  trustees  compared the expense
ratios of the  investment  management  fee, other expenses and total expenses of
the Trust to similar expense ratios of the peer group of large-cap  growth funds
and  noted  that  the  Adviser's  management  fee  includes   substantially  all
administrative  services of the Trust as well as investment  advisory  services.
The trustees  noted that the Trust's  expense  ratios were above and the Trust's
size was below  average  within this  group.  The  trustees  also noted that the
management  fee structure was the same as that in effect for most of the Gabelli
funds.  The  trustees  did not compare the  management  fee to the fee for other
types of accounts managed by the Adviser.

CONCLUSIONS.  The independent  trustees  concluded that the Trust enjoyed highly
experienced  portfolio  management services and good ancillary services but that
the  intermediate  performance  record was poor and that the expense ratios were
significantly  higher than those of the peer group. The trustees also noted that
the portfolio  manager had previously  achieved  excellent  performance and that
near-term  relative  performance was also improving  although not yet as good as
the trustees  would like to see.  They  concluded  that the  positive  trend and
long-term  record of the  portfolio  manager were  sufficient in relation to the
performance factor to warrant renewal of the investment  management agreement at
this time and that the fee  structure of the Trust in relation to its peer group
should be revisited if both the long-term and short-term performance record were
not strong.  The trustees  concluded  that the  profitability  to the Adviser of
managing  the  Trust  was  reasonable  and that  economies  of scale  were not a
significant factor in their thinking at this time. The trustees did not view the
potential  profitability of ancillary services as material to their decision. On
the basis of the foregoing and without assigning particular weight to any single
conclusion, the independent trustees determined to recommend continuation of the
investment management agreement to the full Board of Trustees.
