ITEM 1. REPORTS TO STOCKHOLDERS.

The Report to Shareholders is attached herewith.


                           THE GABELLI UTILITIES FUND

                                  ANNUAL REPORT
                                DECEMBER 31, 2005




TO OUR SHAREHOLDERS,
      The Sarbanes-Oxley Act requires a Fund's principal executive and financial
officers  to  certify  the  entire   contents  of  the  semi-annual  and  annual
shareholder  reports in a filing with the Securities and Exchange  Commission on
Form N-CSR. This certification  would cover the portfolio  manager's  commentary
and  subjective  opinions  if they are  attached  to or a part of the  financial
statements. Many of these comments and opinions would be difficult or impossible
to certify.
      Because we do not want our portfolio  managers to eliminate their opinions
and/or  restrict their  commentary to historical  facts, we have separated their
commentary from the financial  statements and investment portfolio and have sent
it to  you  separately.  Both  the  commentary  and  the  financial  statements,
including  the  portfolio  of  investments,  will be available on our website at
www.gabelli.com/funds.
      Enclosed are the audited financial statements and the investment portfolio
as of  December  31,  2005 with a  description  of  factors  that  affected  the
performance during the past year.

PERFORMANCE DISCUSSION
      During 2005,  the Gabelli  Utilities  Fund rose 8.36% compared to gains by
the S&P 500 Utility  Index and the average  utility fund  monitored by Lipper of
16.84% and  13.37%,  respectively.  The fourth  quarter  was a tough  period for
utility stocks,  but overall the full year 2005 was a good one for these stocks.
After  positive  moves during the first three  quarters of 2005,  utility stocks
suffered modest declines in the final quarter of the year.
      Looking back at the full year 2005,  the biggest event,  with  significant
positive  long-term  implications,  was the passage of the Energy  Policy Act of
2005. This was the first  comprehensive  energy legislation to be passed in more
than a decade and it was signed into law by President Bush in August. The Energy
Policy Act repealed the 1935 Public Utility Holding Company Act, known as PUHCA.
Repeal of PUHCA removes a number of rules that  restricted  utility  mergers and
acquisitions  in the U.S. For  instance,  the recently  announced  merger of FPL
Group Inc. and Constellation Energy Group could not have taken place if the 1935
PUHCA  rules were still in effect.  The Fund has  investments  in several of the
smaller  and  mid-sized   utilities  that  we  think  are  attractive   takeover
candidates.
      Another  major event of 2005 for utilities was the huge increase in energy
prices. Fuel prices were moving up moderately during the first half of 2005, but
then they soared during the third quarter.  However,  during the fourth quarter,
fuel prices did not retreat much at all.
      The Fund benefited from its large holding in Allegheny  Energy Inc.,  that
rose by 60.5%  during  2005.  Other  major  electric  utility  holdings  helping
performance in 2005 were Edison International,  that went up by 36.2%, UniSource
Energy  Corp.,  up  29.4%,  and  Electric  Power  Development  Corp.,  up 22.9%.
Companies in diverse  sectors that  contributed  to returns in 2005 included the
cable and wireless  company Rogers  Communications  Inc.  (+61.6%),  the Denmark
based  telecom TDC A/S  (+63.0%),  and the Spanish  utility  ENDESA SA (+28.5%),
which at the end of 2005 entered into talks to be acquired.
      The  Fund's  performance  was  dimmed by its  holding  in  Duquesne  Light
Holdings  Inc.,  that fell by 13.4%  during  2005 and also by Energy East Corp.,
that  declined  by 14.5%  for the same  period.  Cable  and  satellite  holdings
Echostar  Communications  Corp.  (-18.3%) and Cablevision  Systems Corp. (-5.7%)
also delivered a negative impact on our Fund.

                                           Sincerely yours,

                                           /s/ Bruce N. Alpert

THE GABELLI UTILITIES FUND
DISCLOSURE OF FUND EXPENSES (UNAUDITED)
For the Six Month Period from July 1, 2005 through December 31, 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 year ended December 31, 2005.

Class A, Class B, and Class C Shares, respectively, of the distributions paid in
2005 were a nontaxable  return of capital which should be deducted from the cost
basis of the securities held as of the payment date.
U.S. GOVERNMENT INCOME:
The  percentage of the ordinary  income  dividend paid by the Fund during fiscal
year 2005 which was derived from U.S. Treasury securities was 6.34%. Such income
is  exempt  from  state  and  local tax in all  states.  However,  many  states,
including  New York and  California,  allow a tax exemption for a portion of the
income  earned only if a mutual fund has  invested at least 50% of its assets at
the end of each quarter of the Fund's fiscal year in U.S. Government securities.
The Gabelli Utilities Fund did not meet this strict  requirement in 2005. Due to
the  diversity  in state and local tax law, it is  recommended  that you consult
your personal tax adviser as to the applicability of the information provided to
your specific situation.

THE GABELLI UTILITIES FUND
NOTES TO FINANCIAL STATEMENTS
================================================================================

1.  ORGANIZATION.  The Gabelli  Utilities Fund (the "Fund") was organized on May
18,  1999 as a Delaware  statutory  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 commenced  operations on August 31,
1999.  The Fund's  primary  objective is to provide a high level of total return
through a combination of capital appreciation and current income.

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 with remaining maturities of 60 days or less that
are not  credit  impaired  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 average of the latest 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.

                                       10

THE GABELLI UTILITIES FUND
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
================================================================================

REPURCHASE  AGREEMENTS.  The Fund may  enter  into  repurchase  agreements  with
primary  government  securities dealers recognized by the Federal Reserve Board,
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.  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 102% 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.
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. At December
31, 2005, there were no open repurchase agreements.

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 translations.  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 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 December 31, 2005,  there were no open forward  foreign  exchange
contracts.

FOREIGN CURRENCY TRANSLATIONS.  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 current exchange
rates.  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 that 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  currency
translations.  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.

                                       11

THE GABELLI UTILITIES FUND
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
================================================================================

FOREIGN  SECURITIES.  The Fund  may  directly  purchase  securities  of  foreign
issuers.  Investing in securities of foreign issuers  involves special risks not
typically  associated  with investing in securities of U.S.  issuers.  The risks
include  possible  revaluation of currencies,  the ability to repatriate  funds,
less complete financial information about companies, and possible future adverse
political  and  economic  developments.  Moreover,  securities  of many  foreign
issuers and their markets may be less liquid and their prices more volatile than
those of securities of comparable U.S. issuers.

FOREIGN  TAXES.  The Fund may be subject to  foreign  taxes on income,  gains on
investments,  or currency  repatriation,  a portion of which may be recoverable.
The Fund will accrue such taxes and  recoveries  as  applicable,  based upon its
current interpretation of tax rules and regulations that exist in the markets in
which it invests.

RESTRICTED  AND  ILLIQUID  SECURITIES.  The Fund may invest up to 15% of its net
assets in  securities  for which the markets are illiquid.  Illiquid  securities
include  securities the disposition of which is subject to substantial  legal or
contractual  restrictions.  The sale of illiquid  securities often requires more
time and  results  in higher  brokerage  charges or dealer  discounts  and other
selling  expenses  than does the sale of  securities  eligible  for  trading  on
national securities  exchanges or in the  over-the-counter  markets.  Restricted
securities  may  sell at a price  lower  than  similar  securities  that are not
subject to  restrictions  on resale.  Securities  freely salable among qualified
institutional  investors  under  special  rules  adopted by the  Securities  and
Exchange  Commission  ("SEC") may be treated as liquid if they satisfy liquidity
standards  established by the Board. The continued  liquidity of such securities
is not as well assured as that of publicly  traded  securities,  and accordingly
the Board will monitor their liquidity.

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 on the accrual
basis.  Premiums  and  discounts  on debt  securities  are  amortized  using the
effective  yield  to  maturity  method.  Dividend  income  is  recorded  on  the
ex-dividend date except for certain  dividends which are recorded as soon as the
Fund is informed of the dividend.

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  ("NAV")  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 borne solely by the class incurring the expense.

CUSTODIAN FEE CREDITS. When cash balances are maintained in the custody account,
the Fund receives  credits which are used to offset  custodian  fees.  The gross
expenses paid under the custody  arrangement  are included in custodian  fees in
the  Statement of  Operations  with the  corresponding  expense  offset shown as
"custodian fee credits".

DIVIDENDS AND  DISTRIBUTIONS  TO  SHAREHOLDERS.  Dividends and  distributions to
shareholders are recorded on the ex-dividend date. Distributions to shareholders
are based on income and 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.  Distributions
made in excess of current  earnings  and profits on a tax basis are treated as a
non-taxable return of capital.  These book/tax  differences are either temporary
or  permanent  in  nature.  To  the  extent  these  differences  are  permanent,
adjustments are made to the  appropriate  equity accounts in the period when the
differences arise. These reclassifications have no impact on the NAV of the Fund
and  the  calculation  of net  investment  income  per  share  in the  Financial
Highlights  excludes  these  adjustments.  For the year ended December 31, 2005,
reclassifications  were made to decrease  accumulated  net investment  income by
$89,548 and decrease accumulated distributions in excess of net realized gain on
investments and foreign  currency  transactions by $2,047,324 with an offsetting
adjustment to additional paid-in capital.

The tax character of distributions paid during the years ended December 31, 2005
and December 31, 2004 was as follows:

Since  January 2000,  the Fund has had a fixed  distribution  policy.  Under the
policy,  the Fund declares and pays monthly  distributions  from net  investment
income,   capital  gains,  and  paid  in  capital.  The  actual  source  of  the
distribution is determined  after the end of the year.  Pursuant to this policy,
distributions during the year were made in excess of required distributions.  To
the extent such  distributions were made from current earnings and profits, they
were considered  ordinary income or long-term  capital gains. The Fund's current
distribution  policy  may  restrict  the  Fund's  ability  to  pass  through  to
shareholders all of its net realized  long-term  capital gains as a Capital Gain
Dividend,  subject to the maximum  federal income tax rate of 15%, and may cause
such gains to be treated as ordinary  income subject to a maximum federal income
tax rate of 35%. The Fund continues to evaluate its distribution policy in light
of  ongoing  economic  and  market  conditions  and may change the amount of the
monthly  distributions in the future.  The current  annualized rate is $0.84 per
share.

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.

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
Officers and Trustees of the Fund who are affiliated persons of the Adviser. The
Adviser  contractually agreed to waive investment advisory fees and/or reimburse
expenses of the Fund to the extent  necessary to maintain the  annualized  total
operating expenses for Class AAA, Class A, Class B, and Class C at 2.00%, 2.00%,
2.75%, and 2.75%, respectively, of average daily net assets. The Fund is obliged
to repay the Adviser for a period of two fiscal years  following the fiscal year
in which the Adviser  reimbursed  the Fund only to the extent that the operating
expenses of the Fund fall below 2.00%,  2.00%, 2.75%, and 2.75% of average daily
net assets for Class AAA, Class A, Class B, and Class C Shares, respectively. No
expense  reimbursements  were made by the Adviser during 2004 and 2005 and there
is no amount owed to the Adviser by the Fund at December 31, 2005.

4.  DISTRIBUTION  PLAN.  The Fund's Board has adopted a  distribution  plan (the
"Plan")  for each class of shares  pursuant  to Rule  12b-1  under the 1940 Act.
Gabelli & Company,  Inc.  ("Gabelli &  Company"),  an  affiliate of the Adviser,
serves as  distributor  of the Fund.  Under the Class AAA, Class A, Class B, and
Class C Share  Plans,  payments  are  authorized  to Gabelli & Company at annual
rates of 0.25%, 0.25%, 1.00%, and 1.00%, respectively,  of the average daily net
assets of those classes,  the annual  limitations under each Plan. Such payments
are accrued daily and paid monthly.

5. PORTFOLIO SECURITIES. Purchases and proceeds from the sales of securities for
the year ended December 31, 2005, other than short-term  securities,  aggregated
$252,405,989 and $32,673,663, respectively.

6. SHARES OF  BENEFICIAL  INTEREST.  The Fund  currently  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  approximately eight years after the original purchase.  The applicable
CDSC is equal to a  declining  percentage  of the lesser of the NAV per share at
the date of 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.  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,  Class A, Class B, and Class C Shares that are  redeemed or exchanged on or
before the  seventh  day after the date of a  purchase.  (From  November 1, 2004
through  June 14, 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 years ended  December 31, 2005 and December 31, 2004 amounted to
$20,804 and $4,853, respectively.

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.

Transactions in shares of beneficial interest were as follows:

7.  TRANSACTIONS  WITH AFFILIATES.  During the year ended December 31, 2005, the
Fund paid  brokerage  commissions  of $307,050  to Gabelli & Company.  Gabelli &
Company has informed the Fund that it received  commissions  (sales  charges and
underwriting fees) from investors on sales and redemptions of Fund shares during
the year ended December 31, 2005 in the amount of $503,467.

The cost of calculating  the Fund's NAV per share is a Fund expense  pursuant to
the Advisory  Agreement between the Fund and the Adviser.  During the year ended
December 31, 2005, the Fund  reimbursed the Adviser  $45,000 in connection  with
the cost of  computing  the  Fund's  NAV,  which is  included  in  miscellaneous
expenses in the Statement of Operations.

8. CONCENTRATION  RISKS. The Fund invests a high percentage of its assets in the
utilities  sector.  As a result,  the Fund may be more  susceptible to economic,
political, and regulatory developments, positive or negative, and may experience
increased  volatility  to the  Fund's  NAV and a  magnified  effect in its total
return.

9.  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.

10. 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 trading practices involving certain funds managed by the Adviser.
GAMCO  Investors,  Inc., the Adviser's  parent  company,  is responding to these
requests for documents and testimony.  On a separate matter,  in September 2005,
the Adviser was informed by the staff of the SEC that the staff may recommend to
the Commission that an  administrative  remedy and a monetary  penalty be sought
from the Adviser in connection with the actions of two of seven closed-end funds
managed by the Adviser relating to Section 19(a) and Rule 19a-1 of the 1940 Act.
These  provisions  require  registered  investment  companies to provide written
statements to shareholders  when a dividend is made from a source other than net
investment  income.  While the two closed-end  funds sent annual  statements and
provided other  materials  containing this  information,  the funds did not send
written  statements to shareholders with each distribution in 2002 and 2003. The
Adviser  believes  that all of the  funds  are now in  compliance.  The  Adviser
believes  that these  matters  would have no effect on the Fund or any  material
adverse effect on the Adviser or its ability to manage the Fund.

THE GABELLI UTILITIES FUND
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
===============================================================================

To the Shareholders and Board of Trustees of
The Gabelli Utilities Fund

We have  audited the  accompanying  statement of assets and  liabilities  of The
Gabelli Utilities Fund (the "Fund"),  including the schedule of investments,  as
of December 31, 2005, and the related  statement of operations for the year then
ended,  the statements of changes in net assets for each of the two years in the
period  then  ended,  and the  financial  highlights  for  each  of the  periods
indicated therein.  These financial  statements and financial highlights are the
responsibility  of the Fund's  management.  Our  responsibility is to express an
opinion on these  financial  statements  and financial  highlights  based on our
audits.

We conducted our audits in accordance  with the standards of the Public  Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material  misstatement.  We were
not engaged to perform an audit of the Fund's  internal  control over  financial
reporting.  Our audits included consideration of internal control over financial
reporting as a basis for designing audit  procedures that are appropriate in the
circumstances,  but  not  for  the  purpose  of  expressing  an  opinion  on the
effectiveness  of  the  Fund's  internal   control  over  financial   reporting.
Accordingly,  we express no such opinion. An audit also includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements and financial  highlights,  assessing the accounting  principles used
and  significant  estimates  made by  management,  and  evaluating  the  overall
financial  statement  presentation.  Our  procedures  included  confirmation  of
securities  owned as of December 31,  2005,  by  correspondence  with the Fund's
custodian and brokers. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion,  the financial  statements and financial  highlights referred to
above present fairly, in all material  respects,  the financial  position of The
Gabelli  Utilities  Fund at December 31, 2005, the results of its operations for
the year then ended,  the changes in its net assets for each of the two years in
the period  then ended,  and the  financial  highlights  for each of the periods
indicated  therein,  in  conformity  with  U.S.  generally  accepted  accounting
principles.


                                                          /s/ ERNST & YOUNG, LLP

          aggregate amount of all such permissible  non-audit  services provided
          to  the  registrant,   Gabelli  and  any  Covered  Services   Provider
          constitutes  not more than 5% of the total amount of revenues  paid by

          which  the  permissible  non-audit  services  are  provided;  (ii) the
          permissible  non-audit  services were not recognized by the registrant
          at the time of the engagement to be non-audit services; and (iii) such

                           (b) N/A

                           (c) 100%

     (f)  The  percentage  of  hours  expended  on  the  principal  accountant's
          engagement to audit the registrant's financial statements for the most
          recent fiscal year that were  attributed to work  performed by persons
          other than the principal accountant's  full-time,  permanent employees
          was zero percent (0%).

     (g)  The aggregate non-audit fees billed by the registrant's accountant for
          services rendered to the registrant,  and rendered to the registrant's
          investment  adviser  (not  including  any  sub-adviser  whose  role is
          primarily  portfolio  management and is subcontracted with or overseen
          by another investment adviser), and any entity controlling, controlled
          by, or under common  control with the adviser  that  provides  ongoing
          services to the  registrant  for each of the last two fiscal  years of
          the registrant was $68,600 in 2005 and $68,400 in 2004.

     (h)  The  registrant's  audit  committee  of the  board  of  directors  has
          considered  whether the  provision  of  non-audit  services  that were
          rendered to the  registrant's  investment  adviser (not  including any
          sub-adviser  whose  role  is  primarily  portfolio  management  and is
          subcontracted with or overseen by another investment adviser), and any
          entity  controlling,  controlled  by, or under common control with the
          investment  adviser that provides  ongoing  services to the registrant
          that were not  pre-approved  pursuant to paragraph  (c)(7)(ii) of Rule
          2-01 of Regulation S-X is compatible  with  maintaining  the principal
          accountant's independence.
