+++  Effective in 2008, a change in accounting policy was adopted with regard to
     the calculation of the portfolio turnover rate. Had this policy been
     adopted retroactively, the portfolio turnover rate for the fiscal years
     ended December 31, 2007, 2006, 2005, 2004, and 2003 would have been 98%,
     65%, 59%, 72%, and 56%, respectively.

     recharacterization at fiscal year end.

(a)  Calculated based upon average common shares outstanding on the record dates
     throughout the periods.

(b)  The ratios do not include a reduction of expenses for custodian fee credits
     on cash balances maintained with the custodian. Including such custodian
     fee credits for the fiscal years ended December 31, 2007 and December 31,
     2006, the ratios of operating expenses to average net assets attributable
     to common shares net of advisory fee reduction would have been 1.74% and
     2.05%, respectively, and the ratios of operating expenses to average net
     assets including liquidation value of preferred shares would have been
     1.17% and 1.37%, respectively. For the six months ended June 30, 2008 and
     the fiscal year ended December 31, 2005, the effect of the custodian fee
     credits was minimal.

(c)  The Fund incurred dividend expense on securities sold short for the fiscal
     year ended December 31, 2006. If dividend expense had not been incurred,
     the ratio of operating expenses to average net assets attributable to
     common shares would have been 2.06% and the ratio of operating expenses to
     average net assets including liquidation value of preferred shares would
     have been 1.37%. For the fiscal year ended December 31, 2007, the effect of
     the dividend expense on securities sold short was minimal.

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

1. ORGANIZATION. The Gabelli Convertible and Income Securities Fund Inc. (the
"Fund") is a diversified closed-end 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 a diversified open-end management investment company and commenced
investment operations on July 3, 1989 as The Gabelli Convertible Securities
Fund, Inc. The Board of Directors (the "Board"), 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.

     Effective August 1, 2002, the Fund changed its name to The Gabelli
Convertible and Income Securities Fund Inc. Consistent with its new name, under
normal market conditions, the Fund will invest at least 80% of its net assets in
a combination of convertible securities and income producing securities (the
"80% Policy"). The Fund expects to continue its practice of focusing on
convertible securities to the extent attractive opportunities are available. The
80% Policy may be changed without shareholder approval. However, the Fund has
adopted a policy to provide shareholders with notice at least 60 days prior to
the implementation of any change in the 80% Policy.

2. SIGNIFICANT ACCOUNTING POLICIES. The preparation of financial statements in
accordance with United States ("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 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 a foreign market are generally
valued at the preceding closing values of such securities on the relevant
market, but may be fair valued pursuant to procedures established by the Board
if market conditions change significantly after the close of the foreign market
but prior to the close of business on the day the securities are being valued.
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 fair valued 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 fair valued as determined by 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

              NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)

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.

     On January 1, 2008, the Fund adopted Statement of Financial Accounting
Standard No. 157, "Fair Value Measurements" ("SFAS 157") that clarifies the
definition of fair value for financial reporting, establishes a framework for
measuring fair value, and requires additional disclosures about the use of fair
value measurements. The three levels of the fair value hierarchy under SFAS 157
are described below:

     -    Level 1 - quoted prices in active markets for identical securities;

     -    Level 2 - other significant observable inputs (including quoted prices
          for similar securities, interest rates, prepayment speeds, credit
          risk, etc.); and

     -    Level 3 - significant unobservable inputs (including the Fund's
          determinations as to the fair value of investments).

     The inputs or methodology used for valuing securities are not necessarily
an indication of the risk associated with investing in those securities. The
summary of inputs used to value the Fund's net assets as of June 30, 2008 is as
follows:

*    Other financial instruments are derivative instruments not reflected in the
     Schedule of Investments, such as futures, forwards, and swaps which are
     valued at the unrealized appreciation/depreciation on the investment.

significant unobservable inputs were used to determine fair value:

     In March 2008, The Financial Accounting Standards Board (The "FASB") issued
Statement of Financial Accounting Standard No. 161, "Disclosures about
Derivative Instruments and Hedging Activities" ("SFAS 161") that is effective
for fiscal years beginning after November 15, 2008. SFAS 161 is intended to
improve financial reporting for derivative instruments by requiring enhanced
disclosure that enables investors to understand how and why an entity uses
derivatives, how derivatives are accounted for, and how derivative instruments
affect an entity's results of operations and financial position. Management is
currently evaluating the implications of SFAS 161 on the Fund's financial
statement disclosures.

     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


                                       13


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

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 June 30,
2008, there were no open repurchase agreements.

     SWAP AGREEMENTS. The Fund may enter into equity and contract for difference
swap transactions. The use of swaps and caps is a highly specialized activity
that involves investment techniques and risks different from those associated
with ordinary portfolio transactions. In a swap, a set of future cash flows are
exchanged between two counterparties. One of these cash flow streams will
typically be based on a reference interest rate combined with the performance of
a notional value of shares of a stock. The other will be based on the
performance of the shares of a stock. There is no assurance that the swap
contract counterparties will be able to meet their obligations pursuant to a
swap contract or that, in the event of default, the Fund will succeed in
pursuing contractual remedies. The Fund thus assumes the risk that it may be
delayed in or prevented from obtaining payments owed to it pursuant to a swap
contract. The creditworthiness of the swap contract counterparties is closely
monitored in order to minimize this risk. Depending on the general state of
short-term interest rates and the returns on the Fund's portfolio securities at
that point in time, such a default could negatively affect the Fund's ability to
make dividend payments. In addition, at the time the a swap transaction reaches
its scheduled termination date, there is a risk that the Fund will not be able
to obtain a replacement transaction or that the terms of the replacement will
not be as favorable as on the expiring transaction. If this occurs, it could
have a negative impact on the Fund's ability to make dividend payments.

     The use of derivative instruments involves, to varying degrees, elements of
market and counterparty risk in excess of the amount recognized below.

     Unrealized gains related to swaps are reported as an asset and unrealized
losses are reported as a liability in the Statement of Assets and Liabilities.
The change in value of swaps, including the accrual of periodic amounts of
interest to be paid or received on swaps, is reported as unrealized gains or
losses in the Statement of Operations. A realized gain or loss is recorded upon
payment or receipt of a periodic payment or termination of swap agreements.

     The Fund has entered into a contract for difference swap agreement with
Bear, Stearns International Limited. Details of the swap at June 30, 2008 are as
follows:

     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. Upon entering into a futures
contract, the


                                       14



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

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 fluctuations in the value
of the contract, which are included in unrealized appreciation/depreciation on
investments and futures contracts. The Fund recognizes a realized gain or loss
when the contract is closed.

     There are several risks in connection with the use of futures contracts as
a hedging instrument. 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. At June 30, 2008, there were no open
futures contracts.

     SECURITIES SOLD SHORT. The Fund may enter into short sale transactions.
Short selling involves selling securities that may or may not be owned and, at
times, borrowing the same securities for delivery to the purchaser, with an
obligation to replace such borrowed securities at a later date. The proceeds
received from 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 an 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. The Fund did not hold any short positions as
of June 30, 2008.

     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 June 30, 2008, there were no open forward foreign
exchange contracts.

     FOREIGN CURRENCY TRANSLATIONS. The books and records of the Fund are
maintained in 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.

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

     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 saleable among qualified
institutional investors under special rules adopted by the 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.

     CUSTODIAN FEE CREDITS AND INTEREST EXPENSE. 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, if any, shown as "custodian fee credits." When cash balances are
overdrawn, the Fund is charged an overdraft fee of 2.00% above the federal funds
rate on outstanding balances. This amount, if any, would be shown as "interest
expense" in the Statement of Operations.

     DISTRIBUTIONS TO SHAREHOLDERS. Distributions to common 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
and foreign currency transactions held by the Fund, timing differences, and
differing characterizations of distributions made by the Fund. Distributions
from net investment income include net realized gains on foreign currency
transactions. These book/tax differences are either temporary or permanent in
nature. To the extent these differences are permanent, adjustments are made to
the appropriate capital accounts in the period when the differences arise. These
reclassifications have no impact on the NAV of the Fund.

     Distributions to shareholders of the Fund's 6.00% Series B Cumulative
Preferred Stock and Series C Auction Rate Cumulative Preferred Stock
("Cumulative Preferred Stock") are recorded 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 (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.

     As of December 31, 2007, the components of accumulated earnings/(losses) on
a tax basis were as follows:

     adjustments from partnerships, and five year qualified tax gain.

     FASB Interpretation No. 48, "Accounting for Uncertainty in Income Taxes, an
Interpretation of FASB Statement No. 109" (the "Interpretation") established a
minimum threshold for financial statement recognition of the benefit of
positions taken in filing tax returns (including whether the Fund is taxable in
a particular jurisdiction) and required certain expanded tax disclosures.

     For the six months ended June 30, 2008, the Fund did not have any liability
for any unrecognized tax benefits. The Fund recognizes interest and penalties,
if any, related to unrecognized tax benefits as income tax expenses in the
Statement of Operations. The Fund is not subject to examination by U.S. federal
tax authorities for tax years before 2004 and by state tax authorities for tax
years before 2003.

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 including the liquidation value of preferred stock. 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 NAV of the common shares of the Fund,
including distributions and advisory fee subject to reduction, does not exceed
the stated dividend rate or corresponding swap rate of each particular series of
the Cumulative Preferred Stock for the fiscal year.

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

     The Fund's total return on the NAV of the Common Shares is monitored on a
monthly basis to assess whether the total return on the NAV of the Common Shares
exceeds the stated dividend rate or corresponding swap rate of each particular
series of Cumulative Preferred Stock for the period. For the six months ended
June 30, 2008, the Fund's total return on the NAV of the Common Shares did not
exceed the stated dividend rate or net swap expense on any outstanding Preferred
Stock. Thus, management fees with respect to the liquidation value of the
preferred stock assets were reduced by $243,392.

     During the six months ended June 30, 2008, the Fund paid brokerage
commissions on security trades of $15,159 to Gabelli & Company, Inc. ("Gabelli &
Company"), an affiliate of the Adviser.

     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 six
months ended June 30, 2008, the Fund paid or accrued $22,500 to the Adviser in
connection with the cost of computing the Fund's NAV.

     As per the approval of the Board, the Fund compensates officers of the
Fund, who are employed by the Fund and are not employed by the Adviser (although
the officers may receive incentive based variable compensation from affiliates
of the Adviser, and pays its allocated portion of the cost of the Fund's Chief
Compliance Officer). For the six months ended June 30, 2008, the Fund paid or
accrued $93,592, which is included in payroll expenses in the Statement of
Operations.

     The Fund pays each Director who is not considered to be an affiliated
person an annual retainer of $5,000 plus $750 for each Board meeting attended
and they are reimbursed for any out of pocket expenses incurred in attending
meetings. All Board committee members receive $500 per meeting attended. In
addition, the Audit Committee Chairman receives an annual fee of $3,000, the
Nominating Committee Chairman receives an annual fee of $2,000, and the Lead
Director receives an annual fee of $1,000. Directors who are directors or
employees of the Adviser or an affiliated company receive no compensation or
expense reimbursement from the Fund.

4. PORTFOLIO SECURITIES. Purchases and proceeds from the sales of securities for
the six months ended June 30, 2008, other than short-term securities and U.S.
Government obligations, aggregated $22,899,174 and $20,526,113, respectively.

     Purchases and proceeds from the sales of U.S. Government obligations for
the six months ended June 30, 2008, other than short-term obligations,
aggregated $3,347,403 and $15,448,000, respectively.

5. CAPITAL. The charter permits the Fund to issue 998,000,000 shares of common
stock (par value $0.001). The Board has authorized the repurchase of up to
500,000 common shares on the open market when the shares are trading at a
discount of 10% or more (or such other percentage as the Board may determine
from time to time) from the NAV of the shares. During the six months ended June
30, 2008, the Fund did not repurchase any shares of its common stock in the open
market.

     Transactions in common stock were as follows:

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

     The Fund's Articles of Incorporation authorize the issuance of up to
2,000,000 shares of $0.001 par value Cumulative Preferred Stock. The Cumulative
Preferred Stock is senior to the common stock and results in the financial
leveraging of the common stock. Such leveraging tends to magnify both the risks
and opportunities to common shareholders. Dividends on shares of the Cumulative
Preferred Stock are cumulative. The Fund is required by the 1940 Act and by the
Articles Supplementary 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 6.00% Series B and Series C Auction Rate Cumulative Preferred Stock at
redemption prices of $25.00 and $25,000, respectively, 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 coverage requirements could restrict the Fund's ability to pay
dividends to common shareholders and could lead to sales of portfolio securities
at inopportune times. The income received on the Fund's assets may vary in a
manner unrelated to the fixed and variable rates, which could have either a
beneficial or detrimental impact on net investment income and gains available to
common shareholders.

     At the Fund's February 19, 2008 Board meeting, the Board approved the
filing of a shelf registration with the SEC. The shelf offering went effective
June 12, 2008 and gives the Fund the ability to offer additional preferred
shares and promissory notes.

     On March 18, 2003, the Fund received net proceeds of $23,994,241 after
underwriting discounts of $787,500 and offering expenses of $218,259 from the
public offering of 1,000,000 shares of 6.00% Series B Cumulative Preferred
Stock. Commencing March 19, 2008 and thereafter, the Fund, at its option, may
redeem the 6.00% Series B Cumulative Preferred Stock in whole or in part at the
redemption price at any time. The Board has authorized the repurchase on the
open market at prices less than the $25 liquidation value of the Cumulative
Preferred Stock. During the six months ended June 30, 2008, the Fund did not
repurchase any shares of 6.00% Series B Cumulative Preferred Stock. At June 30,
2008, 990,800 shares of 6.00% Series B Cumulative Preferred Stock were
outstanding and accrued dividends amounted to $20,642.

     On March 18, 2003, the Fund received net proceeds of $24,531,741 after
underwriting discounts of $250,000 and offering expenses of $218,259 from the
public offering of 1,000 shares of Series C Auction Rate Cumulative Preferred
Stock. The dividend rate, as set by the auction process, which is generally held
every seven days, is expected to vary with short-term interest rates. If the
number of Series C Auction Rate Cumulative Preferred Stock subject to bid orders
by potential holders is less than the number of Series C Auction Rate Cumulative
Preferred Stock subject to sell orders, then the auction is considered to be a
failed auction, and the dividend rate will be the maximum rate. In that event,
holders that have submitted sell orders may not be able to sell any or all of
the Series C Auction Rate Cumulative Preferred Stock for which they have
submitted sell orders. On June 25, 2008, the Fund, as authorized by the Board,
redeemed 100% (1,000 shares) of its Series C Auction Rate Cumulative Preferred
Stock (the "Series C Preferred Stock"). Shareholders of the Series C Preferred
Stock received the redemption price of $25,000 per share, which was equal to the
liquidation preference of the Series C Preferred Stock, together with any
accumulated and unpaid dividends, for each of his or her shares of Series C
Preferred Stock redeemed.

     The holders of Cumulative Preferred Stock generally are entitled to one
vote per share held on each matter submitted to a vote of shareholders of the
Fund and will vote together with holders of common stock as a single class. The
holders of Cumulative Preferred Stock voting together as a single class also
have the right currently to elect two Directors and under certain circumstances
are entitled to elect a majority of the Board of Directors. In addition, the
affirmative vote of a majority of the votes entitled to be cast by holders of
all outstanding shares of the preferred stock, voting as a single class, will be
required to approve any plan of reorganization adversely affecting the preferred

class, voting separately, of the Fund's outstanding voting stock must approve
the conversion of the Fund from a closed-end to an open-end investment company.
The approval of a majority (as defined in the 1940 Act) of the outstanding
preferred stock and a majority (as defined in the 1940 Act) of the Fund's
outstanding voting securities are required to approve certain other actions,
including changes in the Fund's investment objectives or fundamental investment
policies.

6. TRANSACTIONS IN SECURITIES OF AFFILIATED ISSUERS. The 1940 Act defines
affiliated issuers as those in which the Fund's holdings of an issuer represent
5% or more of the outstanding voting securities of the issuer. A summary of the
Fund's transactions in the securities of this issuer during the six months ended
June 30, 2008 is set forth below:



                                                  NET CHANGE                    PERCENT

7. 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.

8. OTHER MATTERS. On April 24, 2008, the Adviser entered into an administrative
settlement with the SEC to resolve the SEC's inquiry regarding prior frequent
trading activity in shares of the GAMCO Global Growth Fund (the "Global Growth
Fund") by one investor who was banned from the Global Growth Fund in August
2002. In the settlement, the SEC found that the Adviser had violated Section
206(2) of the Investment Advisers Act, Section 17(d) of the 1940 Act and Rule
17d-1 thereunder, and had aided and abetted and caused violations of Section
12(d)(1)(B)(i) of the 1940 Act. Under the terms of the settlement, the Adviser,
while neither admitting nor denying the SEC's findings and allegations, agreed,
among other things, to pay the previously reserved total of $16 million
(including a $5 million penalty), of which at least $11 million will be
distributed to shareholders of the Global Growth Fund in accordance with a plan
to be developed by an independent distribution consultant and approved by the
independent directors of the Global Growth Fund and the staff of the SEC, and to
cease and desist from future violations of the above referenced federal
securities laws. The settlement will not have a material adverse impact on the
Adviser or its ability to fulfill its obligations under the Advisory Agreement.
On the same day, the SEC filed a civil action against the Executive Vice
President and Chief Operating Officer of the Adviser, alleging violations of
certain federal securities laws arising from the same matter. The officer is
also an officer of the Global Growth Fund and other funds in the Gabelli/GAMCO
fund complex. The officer denies the allegations and is continuing in his
positions with the Adviser and the funds. The Adviser currently expects that any
resolution of the action against the officer will not have a material adverse
impact on the Adviser or its ability to fulfill its obligations under the
Advisory Agreement.

     On a separate matter, in August 2008, the Adviser made an offer to the
staff of the SEC to settle a previously disclosed matter concerning compliance
with Section 19(a) and Rule 19a-1 of the 1940 Act by two closed-end funds
managed by the Adviser. These provisions require registered investment companies
to provide written statements to shareholders when a distribution is made in the
nature of a dividend from a source other than net investment income. While the
two funds sent annual statements and provided other materials containing this
information, the funds did not send the notices required by Rule 19a-1 to
shareholders with each distribution in 2002 and 2003. The Adviser believes that
the funds have been in compliance with Rule 19a-1 since that time. The Adviser
believes that the settlement would have no effect on the funds or any material
adverse effect on the Adviser or its ability to manage the funds. This offer of
settlement is subject to final agreement regarding the specific language of the
SEC's administrative order and other settlement documents and approval by the
SEC.

              NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)

                                  COMMON SHARES
                                CUSIP: 36240B109

We are pleased to report the payment of a distribution in the amount of $0.20
per share payable on June 24, 2008 to shareholders of record on June 16, 2008.
As of the record date, $0.017 per share of the distribution is derived from net
investment income and the remainder of the distribution, or $0.183 per share, is
deemed a return of capital. These estimates are based on earnings as of the
record date. After giving effect to the distribution, the aggregate of the
undistributed net realized losses on the sale of securities and net unrealized
depreciation of portfolio securities is $1,144,111, of which $414,648 represents
net unrealized depreciation of portfolio securities. Prior distributions within
2008 would have similar characterizations. The actual composition of the
distribution may change based on the Fund's investment activity through December
31, 2008. Shareholders will be notified regarding the components of all
distributions for the year and the related tax treatment via Form 1099-DIV in
early 2009.

 BOARD CONSIDERATION AND RE-APPROVAL OF INVESTMENT ADVISORY CONTRACT (UNAUDITED)

At its meeting on May 22, 2008, the Board of Directors ("Board") of the Fund
approved the continuation of the investment advisory contract with the Adviser
for the Fund on the basis of the recommendation by the directors who are not
"interested persons" of the Fund (the "Independent Board Members"). The
following paragraphs summarize the material information and factors considered
by the Independent Board Members as well as their conclusions relative to such
factors.

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

INVESTMENT PERFORMANCE. The Independent Board Members reviewed the short,
medium, and longer-term performance of the Fund against a peer group of
convertible securities and income/preferred stock closed-end funds. The
Independent Board Members noted that the Fund's short, medium, and long-term
comparative performance was in the top quintile to the top half, which was
reasonable particularly in light of the Fund's conservative stance.

PROFITABILITY. The Independent Board Members reviewed summary data regarding the
profitability of the Fund to the Adviser and found the profitability to be
normal. The Independent Board Members also noted that a substantial portion of
the Fund's portfolio transactions were executed by an affiliated broker, and
that the affiliated broker received distribution fees and commissions from the
Fund. The Adviser received a moderate amount of soft dollar benefits (but no
third party research services) from unaffiliated brokers through the Fund's
portfolio brokerage.

ECONOMIES OF SCALE. The Independent Board Members discussed the major elements
of the Adviser's cost structure and the relationship of those elements to
potential economies of scale. The Independent Board Members noted that the Fund
was a closed-end fund and unlikely to realize any economies of scale potentially
available through growth.

SHARING OF ECONOMIES OF SCALE. The Independent Board Members noted that the
investment management fee schedule for the Fund does not take into account any
potential economies of scale.

SERVICE AND COST COMPARISONS. The Independent Board Members compared the expense
ratios of the investment advisory fee, other expenses, and total expenses of the
Fund with similar expense ratios of the peer group of closed-end funds and noted
that the advisory fee includes substantially all administrative services of the
Fund as well as investment advisory services of the Adviser. The Independent
Board Members noted that the Fund's expense ratios were above average and the
Fund's size was below average within the group. The Independent Board Members
were presented with, but did not consider to be material to their decision,
various information comparing the advisory fee with the fee for other types of
accounts managed by the Adviser.

CONCLUSIONS. The Independent Board Members concluded that the Fund enjoyed
highly experienced portfolio management services, good ancillary services, and a
reasonable performance record within its conservative stance. The Independent
Board Members also concluded that the Fund's expense ratios were reasonable in
light of the Fund's size, and that, in part due to the Fund's structure as a
closed-end fund, economies of scale were not a significant factor in their
thinking. The Independent Board Members 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 Board Members determined to recommend continuation of the investment
management agreement to the full Board.
