Gabelli Capital Asset Fund
- --------------------------------

Notes to Financial Statements
June 30, 2003 (Unaudited)

- ---------------
1. Organization
- ---------------

      The Gabelli Capital Asset Fund (the "Fund"), a series of Gabelli Capital
Series Funds, Inc. (the "Company"), was organized on April 8, 1993 as a Maryland
corporation. The Company is a diversified, open-end management investment
company registered under the Investment Company Act of 1940, as amended. The
Fund's primary objective is growth of capital. The Fund commenced investment
operations on May 1, 1995. Shares of the Fund are available to the public only
through the purchase of certain variable annuity and variable life insurance
contracts issued by The Guardian Insurance & Annuity Company, Inc. ("Guardian")
and other selected insurance companies.

- ----------------------------------
2. Significant Accounting Policies
- ----------------------------------

      The preparation of financial statements in accordance with accounting
principles generally accepted in the United States 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
Directors so determines, by such other method as the Board of Directors 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. 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 Board of
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 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. 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.

Securities Transactions and Investment Income.

      Securities transactions are accounted for on the trade date with realized
gain or loss on the sale of 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 and long term 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.

Provision for Income Taxes.

      The Fund has qualified and 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.

      The Fund has a net capital loss carryforward for Federal income tax
purposes at December 31, 2002 of $3,125,346. The capital loss carryforward is
available to reduce future distributions of net capital gains to shareholders
through 2010.

- -------------------------------------
3. Agreements with Affiliated Parties
- -------------------------------------

      Pursuant to a management agreement (the "Management Agreement"), the Fund
will pay Guardian Investor Services LLC (the "Manager") a fee, computed daily
and paid monthly, at the annual rate of 1.00% of the value of the Fund's average
daily net assets. Pursuant to an Investment Advisory Agreement among the Fund,
the Manager and the Adviser, the Adviser, under the supervision of the Company's
Board of Directors and the Manager, manages the Fund's assets in accordance with
the Fund's investment objectives and policies, makes investment decisions for
the Fund, places purchase and sale orders on behalf of the Fund, provides
investment research and provides facilities and personnel required for the
Fund's administrative needs. The Adviser may delegate its administrative role
and currently has done so to PFPC Inc., the Fund's sub-administrator (the
"Sub-Administrator"). The Adviser will supervise the performance of
administrative and professional services provided by others and pays the
compensation of the Sub-Administrator and all officers and Directors of the
Company who are its affiliates. As compensation for its services and the related
expenses borne by the Adviser, the Manager pays the Adviser a fee, computed
daily and paid monthly, at the annual rate of 0.75% of the value of the Fund's
average daily net assets.

- -----------------------
4. Portfolio Securities
- -----------------------

      Purchases and proceeds from the sales of securities for the six months
ended June 30, 2003, other than short term securities, aggregated $13,409,805
and $21,949,279, respectively.

- -------------------------------
5. Transactions with Affiliates
- -------------------------------

      During the six months ended June 30, 2003, the Fund paid brokerage
commissions of $49,488 to Gabelli & Company, Inc. and its affiliates.

      The cost of calculating the Fund's net asset value per share is a Fund
expense pursuant to the Investment Advisory Agreement among the Fund, the
Manager and the Adviser. During the six months ended June 30, 2003, the Fund
reimbursed the Adviser $17,263 in connection with the cost of computing the
Fund's net asset value.

- ------------------
6. Line of Credit.
- ------------------

      The Fund has access to an unsecured line of credit 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. There were no borrowings outstanding at June 30, 2003.

      The average daily amount of borrowings outstanding within the six months
ended June 30, 2003 was $455,359, with a related weighted interest rate of
2.04%. The maximum amount borrowed at any time during the six months ended June
30, 2003 was $3,130,000.

            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 Exchange Act (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 materially affect, the registrant's internal
            control over financial reporting.
