GAMCO International Growth Fund, Inc. Annual Report — December 31, 2014
	Caesar M. P. Bryan
	Portfolio Manager

To Our Shareholders,

For the year ended December 31, 2014, the net asset value (“NAV”) per Class AAA Share of the GAMCO International Growth Fund, Inc. decreased 5.5% compared with a decrease of 4.9% for the Morgan Stanley Capital International (“MSCI”) Europe, Australasia, and the Far East (“EAFE”) Index. See page 3 for additional performance information.

Enclosed are the financial statements, including the schedule of investments, as of December 31, 2014.

Performance Discussion (Unaudited)

We purchase attractively valued companies that we believe have the opportunity to grow earnings more rapidly than average within that company’s local market. We pay close attention to a company’s market position, management, and balance sheet, with particular emphasis on the ability of the company to finance its growth. Generally, we value a company relative to its local market, but where appropriate, we will attempt to benefit from valuation discrepancies between markets. Our primary focus is on security selection and not country allocation, but the Fund will remain diversified by sector and geography. Country allocation is likely to reflect broad, economic, financial, and currency trends, as well as relative size of the market.

The Fund is focused on developed countries and not the emerging markets. We have concentrated the Fund’s investments in the Japan (26.2% of net assets as of December 31, 2014), the United Kingdom (18.7%), Switzerland (18.5%), France (10.1%), and Hong Kong (6.6%). Our exposure to the Japanese markets hurt performance in 2014. Japan slipped back into recession as confidence in Abenomics, an agenda largely focused on stimulus measures, waned. Rising sales taxes, intended to increase government revenues, have been blamed for triggering the downturn by deterring consumer spending.

The financial markets were pretty steady in 2014. Stocks and bonds traded in relatively narrow ranges. Like 2013, the market did not have a full 10% correction, although it came close. Interest rates surprised by quietly falling. Stocks rose through a combination of rising earnings and expanding valuations.

Some of our stronger performing stocks were Naspers Ltd. (3.3% of net assets as of December 31, 2014), a multinational media group whose segments include Internet, pay television, print media and related technology in emerging markets; Novartis AG (3.4%), a Swiss healthcare solutions provider with a large portfolio consisting of medicines, eye care, generic pharmaceuticals, vaccines and diagnostic tools; and Unicharm Corp. (2.2%), a Japanese company mainly engaged in the manufacture and sale of diapers, sanitary health, and pet care products.

Some of our weaker holdings were Kinnevik Investment AB (2.9%), an investment company which manages a portfolio of listed holdings, primarily in the telecommunications and media sectors. In addition, the company invests in small and mid-size companies with significant growth potential, focusing primarily on online, microfinance, and agriculture businesses; Yahoo! Japan Corp. (1.0%), a Japanese internet company formed as a joint venture between the American internet company Yahoo! and the Japanese internet company SoftBank; and Rio Tinto plc (2.5%), an international mining company. Rio Tinto’s business is finding, mining, and processing mineral resources including aluminum, copper, diamonds, gold, and iron ore.

We appreciate your confidence and trust.

	Sincerely yours,
	Bruce N. Alpert
	President

In the current prospectuses dated April 30, 2014, as amended August 25, 2014, the expense ratios for Class AAA, A, C, and I Shares are 2.24%, 2.24%, 2.99%, and 1.99%, respectively, and the net expense ratios in the current prospectuses for these share classes after contractual reimbursements by Gabelli Funds, LLC, (the “Adviser”) are 2.24%, 2.24%, 2.99%, and 1.00%, respectively. See page 10 for the expense ratios for the year ended December 31, 2014. Class AAA and Class I Shares do not have a sales charge. The maximum sales charge for Class A Shares and Class C Shares is 5.75% and 1.00%, respectively.
(a)	Returns represent past performance and do not guarantee future results. Total returns and average annual returns reflect changes in share price, reinvestment of distributions, and are net of expenses. Investment returns and the principal value of an investment will fluctuate. When shares are redeemed, they may be worth more or less than their original cost. Current performance may be lower or higher than the performance data presented. Visit www.gabelli.com for performance information as of the most recent month end. Returns for Class I Shares would have been lower had the Adviser not reimbursed certain expenses. The Fund imposes a 2% redemption fee on shares sold or exchanged within seven days after the date of purchase. Investors should carefully consider the investment objectives, risks, charges, and expenses of the Fund before investing. The prospectuses contain information about these and other matters and should be read carefully before investing. To obtain a prospectus, please visit our website at www.gabelli.com. Investing in foreign securities involves risks not ordinarily associated with investments in domestic issues, including currency fluctuation, economic, and political risks. The Class AAA Share NAVs are used to calculate performance for the periods prior to the issuance of Class A Shares, Class C Shares, and Class I Shares on July 25, 2001, December 17, 2000, and January 11, 2008, respectively. The actual performance of the Class A Shares and Class C Shares would have been lower due to the additional fees and expenses associated with these classes of shares. The actual performance of the Class I Shares would have been higher due to lower expenses related to this class of shares. The MSCI EAFE Index is an unmanaged indicator of international stock market performance, while the Lipper International Large-Cap Growth Fund Classification and the Lipper International Multi-Cap Growth Fund Classification reflect the average performance of mutual funds classified in these particular categories. Dividends are considered reinvested. You cannot invest directly in an index.
(b)	Performance results include the effect of the maximum 5.75% sales charge at the beginning of the period.
(c)	Assuming payment of the 1% maximum contingent deferred sales charge imposed on redemptions made within one year of purchase.

GAMCO International Growth Fund, Inc.
Disclosure of Fund Expenses (Unaudited)
For the Six Month Period from July 1, 2014 through December 31, 2014	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, 2014.

Class I	$1,000.00	$1,018.50	1.33%	$  6.77

* Expenses are equal to the Fund’s annualized expense ratio for the last six months multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half year (184 days), then divided by 365.

Notes to Financial Statements

1. Organization. GAMCO International Growth Fund, Inc. was incorporated on May 25, 1994 in Maryland. 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 long term capital appreciation. The Fund commenced investment operations on June 30, 1995.

2. Significant Accounting Policies. As an investment company, the Fund follows the investment company accounting and reporting guidance, which is part of U.S. generally accepted accounting principles (“GAAP”) that may require the use of management estimates and assumptions in the preparation of its 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 (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 sixty 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 sixty 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. U.S. government obligations with maturities greater than sixty days are normally valued using a model that incorporates market observable data such as reported sales of similar securities, broker quotes, yields, bids, offers, and reference data. Certain securities are valued principally using dealer quotations.

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 with the valuation and changes in valuation of similar securities, including a comparison of foreign securities with the equivalent U.S. dollar value American Depositary Receipt 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.

The Fund employs a fair value model to adjust prices to reflect events affecting the values of certain portfolio securities, which occur between the close of trading on the principal market for such securities (foreign exchanges

Notes to Financial Statements (Continued)

and over-the-counter markets) at the time when net asset values of the Fund are determined. If the Fund’s valuation committee believes that a particular event would materially affect net asset value, further adjustment is considered.

The inputs and valuation techniques used to measure fair value of the Fund’s investments are summarized into three levels as described in the hierarchy 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 Board’s determinations as to the fair value of investments).

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input both individually and in the aggregate that is significant to the fair value measurement. 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 the Fund’s investments in securities by inputs used to value the Fund’s investments as of December 31, 2014 is as follows:

	Valuation Inputs
	Level 1 Quoted Prices			Level 2 Other Significant Observable Inputs			Total Market Value at 12/31/14

TOTAL INVESTMENTS IN SECURITIES – ASSETS		$	1,566,427		$	24,132,679		$	25,699,106

(a) Please refer to the Schedule of Investments for the industry classifications of these portfolio holdings.

During the year ended December 31, 2014, certain foreign securities were transferred from Level 1 to Level 2 due to the application of fair value procedures resulting from volatility in U.S. markets after the close of the foreign markets. The beginning of period value of the securities that transferred from Level 1 to Level 2 during the period amounted to $23,694,407 or 78.85% of net assets as of December 31, 2013. The Fund’s policy is to recognize transfers among Levels as of the beginning of the reporting period.

There were no Level 3 investments held at December 31, 2014 or 2013.

Additional Information to Evaluate Qualitative Information.

General. The Fund uses recognized industry pricing services – approved by the Board and unaffiliated with the Adviser – to value most of its securities, and uses broker quotes provided by market makers of securities not valued by these and other recognized pricing sources. Several different pricing feeds are received to value domestic equity securities, international equity securities, preferred equity securities, and fixed income securities. The data within these feeds is ultimately sourced from major stock exchanges and trading systems where these

12

GAMCO International Growth Fund, Inc.

Notes to Financial Statements (Continued)

securities trade. The prices supplied by external sources are checked by obtaining quotations or actual transaction prices from market participants. If a price obtained from the pricing source is deemed unreliable, prices will be sought from another pricing service or from a broker/dealer that trades that security or similar securities.

Fair Valuation. Fair valued securities may be common and preferred equities, warrants, options, rights, and fixed income obligations. Where appropriate, Level 3 securities are those for which market quotations are not available, such as securities not traded for several days, or for which current bids are not available, or which are restricted as to transfer. Among the factors to be considered to fair value a security are recent prices of comparable securities that are publicly traded, reliable prices of securities not publicly traded, the use of valuation models, current analyst reports, valuing the income or cash flow of the issuer, or cost if the preceding factors do not apply. A significant change in the unobservable inputs could result in a lower or higher value in Level 3 securities. The circumstances of Level 3 securities are frequently monitored to determine if fair valuation measures continue to apply.

The Adviser reports quarterly to the Board the results of the application of fair valuation policies and procedures. These include back testing the prices realized in subsequent trades of these fair valued securities to fair values previously recognized.

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 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 purchase trade date and subsequent sale trade date is included in realized gain/(loss) on investments.

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 inability 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.

Securities Transactions and Investment Income. Securities transactions are accounted for on the trade date with realized gain/(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

13

GAMCO International Growth Fund, Inc.

Notes to Financial Statements (Continued)

the ex-dividend date, except for certain dividends from foreign securities that are recorded as soon after the ex-dividend date as the Fund becomes aware of such dividends.

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 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.

Distributions to Shareholders. 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 GAAP. 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 for federal income tax purposes 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. Permanent differences were primarily due to the tax treatment of currency gains and losses and reclassifications of gains on investments in passive foreign investment companies. These reclassifications have no impact on the NAV of the Fund. For the year ended December 31, 2014, reclassifications were made to increase accumulated net investment loss by $182 and increase accumulated net realized gain on investments and foreign currency transactions by $182.

The tax character of distributions paid durning the years ended December 31, 2014 and 2013 was as follows:

	Year Ended December 31, 2014			Year Ended December 31, 2013
Distributions paid from:
Ordinary income (inclusive of short term capital gains)		$	62,739		$	94,418
Net long term capital gains			841,647			1,366,985
Total distributions paid		$	904,386		$	1,461,403

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.

14

GAMCO International Growth Fund, Inc.

Notes to Financial Statements (Continued)

As of December 31, 2014, the components of accumulated earnings/losses on a tax basis were as follows:

Undistributed ordinary income	$	56,678
Undistributed long term capital gains		3,738
Net unrealized appreciation on investments and foreign currency translations		6,753,309
Total	$	6,813,725

Under the Regulated Investment Company Modernization Act of 2010, the Fund is permitted to carry forward for an unlimited period capital losses incurred. As a result of the rule, post-enactment capital losses that are carried forward will retain their character as either short term or long term capital losses.

At December 31, 2014, the temporary differences between book basis and tax basis net unrealized appreciation were primarily due to mark-to-market adjustments on investments in passive foreign investment companies.

The following summarizes the tax cost of investments and the related net unrealized appreciation at December 31, 2014:

	Cost	Gross Unrealized Appreciation	Gross Unrealized Depreciation	Net Unrealized Appreciation
Investments	$18,938,639	$8,123,055	$(1,362,588)	$6,760,467

The Fund is required to evaluate tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Income tax and related interest and penalties would be recognized by the Fund as tax expense in the Statement of Operations if the tax positions were deemed not to meet the more-likely-than-not threshold. For the year ended December 31, 2014, the Fund did not incur any income tax, interest, or penalties. As of December 31, 2014, the Adviser has reviewed all open tax years and concluded that there was no impact to the Fund’s net assets or results of operations. The Fund’s federal and state tax returns for the prior three fiscal years remain open, subject to examination. On an ongoing basis, the Adviser will monitor the Fund’s tax positions to determine if adjustments to this conclusion are necessary.

3. Investment Advisory Agreement and Other Transactions. 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 Directors of the Fund who are affiliated persons of the Adviser.

The Adviser, effective August 25, 2014, has contractually agreed to waive its investment advisory fee and/or reimburse expenses of Class I Shares to the extent necessary to maintain the total operating expenses (excluding brokerage, acquired fund fees and expenses, interest, taxes, and extraordinary expenses) until at least April 30, 2016 at no more than 1.00% of the value of its average daily net assets. For the year ended December 31, 2014, the Adviser reimbursed the Fund in the amount of $9,385.

The Fund pays each Director who is not considered to be an affiliated person an annual retainer of $1,000 plus $500 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. The Chairman of the Audit Committee and the Lead Director each receive an annual fee of $1,000. A Director may receive a single meeting fee, allocated among the participating funds, for attending certain meetings held on behalf of

15

GAMCO International Growth Fund, Inc.

Notes to Financial Statements (Continued)

multiple funds. Directors who are directors or employees of the Adviser or an affiliated company receive no compensation or expense reimbursement from the Fund.

4. Distribution Plan. The Fund’s Board has adopted a distribution plan (the “Plan”) for each class of shares, except for Class I Shares, pursuant to Rule 12b-1 under the 1940 Act. Under the Class AAA, Class A, and Class C Share Plans, payments are authorized to G.distributors, LLC (the “Distributor”), an affiliate of the Adviser, at annual rates of 0.25%, 0.25%, 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 sales of securities during the year ended December 31, 2014, other than short term securities and U.S. Government obligations, aggregated $3,282,642 and $6,016,454, respectively.

6. Transactions with Affiliates. During the year ended December 31, 2014, the Distributor retained a total of $540 from investors representing commissions (sales charges and underwriting fees) on sales and redemptions of Fund shares.

The cost of calculating the Fund’s NAV per share is a Fund expense pursuant to the Advisory Agreement. The Adviser did not seek a reimbursement during the year ended December 31, 2014.

7. Line of Credit. The Fund participates in an unsecured line of credit of up to $75,000,000 under which it may borrow up to 10% of its net assets from the custodian for temporary borrowing purposes. Borrowings under this arrangement bear interest at the higher of the sum of the overnight LIBOR rate plus 100 basis points or the sum of the federal funds rate plus 100 basis points at the time of borrowing. This amount, if any, would be included in “Interest expense” in the Statement of Operations. At December 31, 2014, there was $156,000 outstanding under the line of credit.

The average daily amount of borrowings outstanding under the line of credit during the year ended December 31, 2014 was $63,671, with a weighted average interest rate of 1.12%. The maximum amount borrowed at any time during the year was $703,000.

8. Capital Stock. The Fund offers four classes of shares – Class AAA Shares, Class A Shares, Class C Shares, and Class I Shares.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of

GAMCO International Growth Fund, Inc.

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of GAMCO International Growth Fund, Inc. (the “Fund”), as of December 31, 2014, 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 five years in the period then ended. 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, 2014, by correspondence with the Fund’s custodian. 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 Fund at December 31, 2014, 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 its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

As of the end of the period covered by the report, the registrant’s Board of Directors has determined that Salvatore J. Zizza is qualified to serve as an audit committee financial expert serving on its audit committee and that he is “independent,” as defined by Item 3 of Form N-CSR.

(e)(1) Disclose the audit committee’s pre-approval policies and procedures described in paragraph (c)(7) of Rule 2-01 of Regulation S-X.

Pre-Approval Policies and Procedures. The Audit Committee (“Committee”) of the registrant is responsible for pre-approving (i) all audit and permissible non-audit services to be provided by the independent registered public accounting firm to the registrant and (ii) all permissible non-audit services to be provided by the independent registered public accounting firm to the Adviser, Gabelli Funds, LLC, and any affiliate of Gabelli Funds, LLC (“Gabelli”) that provides services to the registrant (a “Covered Services Provider”) if the independent registered public accounting firm’s engagement related directly to the operations and financial reporting of the registrant. The Committee may delegate its responsibility to pre-approve any such audit and permissible non-audit services to the Chairperson of the Committee, and the Chairperson must report to the Committee, at its next regularly scheduled meeting after the Chairperson’s pre-approval of such services, his or her decision(s). The Committee may also establish detailed pre-approval policies and procedures for pre-approval of such services in accordance with applicable laws, including the delegation of some or all of the Committee’s pre-approval responsibilities to the other persons (other than Gabelli or the registrant’s officers). Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the permissible non-audit services were not recognized by the registrant at the time of the engagement to be non-audit services; and (ii) such services are promptly brought to the attention of the Committee and approved by the Committee or Chairperson prior to the completion of the audit.

(e)(2) The percentage of services described in each of paragraphs (b) through (d) of this Item that were approved by the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X are as follows:

(b) N/A

(c) 100%

(d) N/A

(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 less than fifty percent.

(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 $33,520 for 2013 and $37,645 for 2014.

(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.

EX-99.CODE ETH

Joint Code of Ethics for Chief Executive

and Senior Financial Officers of the Gabelli/GAMCO/TETON Funds

Each affiliated registered investment company (each a “Company”) is committed to conducting business in accordance with applicable laws, rules and regulations and the highest standards of business ethics, and to full and accurate disclosure — financial and otherwise — in compliance with applicable law. This Code of Ethics, applicable to each Company’s Chief Executive Officer, President, Chief Financial Officer and Treasurer (or persons performing similar functions) (together, “Senior Officers”), sets forth policies to guide you in the performance of your duties.

As a Senior Officer, you must comply with applicable law. You also have a responsibility to conduct yourself in an honest and ethical manner. You have leadership responsibilities that include creating a culture of high ethical standards and a commitment to compliance, maintaining a work environment that encourages the internal reporting of compliance concerns and promptly addressing compliance concerns.

This Code of Ethics recognizes that the Senior Officers are subject to certain conflicts of interest inherent in the operation of investment companies, because the Senior Officers currently or may in the future serve as Senior Officers of each of the Companies, as officers or employees of the investment advisor to the Companies or service providers thereof (the “Advisor”) and/or affiliates of the Advisor (the “Advisory Group”) and as officers or trustees/directors of other registered investment companies and unregistered investment funds advised by the Advisory Group. This Code of Ethics also recognizes that certain laws and regulations applicable to, and certain policies and procedures adopted by, the Companies or the Advisory Group govern your conduct in connection with many of the conflict of interest situations that arise in connection with the operations of the Companies, including:

• the Investment Company Act of 1940, and the rules and regulation promulgated thereunder by the Securities and Exchange Commission (the “1940 Act”);

• the Investment Advisers Act of 1940, and the rules and regulations promulgated thereunder by the Securities and Exchange Commission (the “Advisers Act”);

• the Code of Ethics adopted by each Company pursuant to Rule 17j-1(c) under the 1940 Act (collectively, the “Trust’s 1940 Act Code of Ethics”);

• one or more codes of ethics adopted by the Advisory Group that have been reviewed and approved by those trustees/directors (the “Directors”) of each Company that are not “interested persons” of such Company (the “Independent Directors”) within the meaning of the 1940 Act (the “Advisory Group’s 1940 Act Code of Ethics” and, together with such Company’s 1940 Act Code of Ethics, the “1940 Act Codes of Ethics”);

Revised: July 30, 2014

1

• the policies and procedures adopted by each Company to address conflict of interest situations, such as procedures under Rule 10f-3, Rule 17a-7 and Rule 17e-1 under the 1940 Act (collectively, the “Conflict Policies”); and

• the Advisory Group’s policies and procedures to address, among other things, conflict of interest situations and related matters (collectively, the “Advisory Policies”).

The provisions of the 1940 Act, the Advisers Act, the 1940 Act Codes of Ethics, the Conflict Policies and the Advisory Policies are referred to herein collectively as the “Additional Conflict Rules”.

This Code of Ethics is different from, and is intended to supplement, the Additional Conflict Rules. Accordingly, a violation of the Additional Conflict Rules by a Senior Officer is hereby deemed not to be a violation of this Code of Ethics, unless and until the Directors shall determine that any such violation of the Additional Conflict Rules is also a violation of this Code of Ethics.

Senior Officers Should Act Honestly and Candidly

Each Senior Officer has a responsibility to each Company to act with integrity. Integrity requires, among other things, being honest and candid. Deceit and subordination of principle are inconsistent with integrity.

Each Senior Officer must:

• act with integrity, including being honest and candid while still maintaining the confidentiality of information where required by law or the Additional Conflict Rules;

• comply with the laws, rules and regulations that govern the conduct of each Company’s operations and report any suspected violations thereof in accordance with the section below entitled “Compliance With Code Of Ethics”; and

• adhere to a high standard of business ethics.

Conflicts Of Interest

A conflict of interest for the purpose of this Code of Ethics occurs when your private interests interfere in any way, or even appear to interfere, with the interests of a Company.

Revised: July 30, 2014

Senior Officers are expected to use objective and unbiased standards when making decisions that affect each Company, keeping in mind that Senior Officers are subject to certain inherent conflicts of interest because Senior Officers of a Company also are or may be officers of other Companies and/or the Advisory Group (as a result of which it is incumbent upon you to be familiar with and to seek to comply with the Additional Conflict Rules).

You are required to conduct the business of each Company in an honest and ethical manner, including the ethical handling of actual or apparent conflicts of interest between personal and business relationships. When making any investment, accepting any position or benefits, participating in any transaction or business arrangement or otherwise acting in a manner that creates or appears to create a conflict of interest with respect to each Company where you are receiving a personal benefit, you should act in accordance with the letter and spirit of this Code of Ethics.

If you are in doubt as to the application or interpretation of this Code of Ethics to you as a Senior Officer of a Company, you should make full disclosure of all relevant facts and circumstances to the Chief Compliance Officer of the Advisory Group (the “CCO”) and obtain the approval of the CCO prior to taking action.

Some conflict of interest situations that should always be approved by the CCO, if material, include the following:

• the receipt of any entertainment or non-nominal gift by the Senior Officer, or a member of his or her family, from any company with which a Company has current or prospective business dealings (other than the Advisory Group), unless such entertainment or gift is business related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety;

• any ownership interest in, or any consulting or employment relationship with, of any of the Companies’ service providers, other than the Advisory Group; or

• a direct or indirect financial interest in commissions, transaction charges or spreads paid by a Company for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Senior Officer’s employment by the Advisory Group, such as compensation or equity ownership.

Disclosures

It is the policy of each Company to make full, fair, accurate, timely and understandable disclosure in compliance with all applicable laws and regulations in all reports and documents that such Company files with, or submits to, the Securities and Exchange Commission or a national securities exchange and in all other public

communications made by such Company. As a Senior Officer, you are required to promote compliance with this policy and to abide by such Company’s standards, policies and procedures designed to promote compliance with this policy.

Each Senior Officer must:

• familiarize himself or herself with the disclosure requirements applicable to each Company as well as the business and financial operations of each Company; and

• not knowingly misrepresent, or cause others to misrepresent, facts about any Company to others, including to the Directors, such Company’s independent auditors, such Company’s counsel, any counsel to the Independent Directors, governmental regulators or self-regulatory organizations.

Compliance With Code Of Ethics

If you know of or suspect a violation of this Code of Ethics or other laws, regulations, policies or procedures applicable to the Company, you must report that information on a timely basis to the CCO or report it anonymously by following the “whistle blower” policies adopted by the Advisory Group from time to time. No one will be subject to retaliation because of a good faith report of a suspected violation.

Each Company will follow these procedures in investigating and enforcing this Code of Ethics, and in reporting on this Code of Ethics:

• the CCO will take all appropriate action to investigate any actual or potential violations reported to him or her;

• violations and potential violations will be reported to the Board of Directors of each affected Company after such investigation;

• if the Board of Directors determines that a violation has occurred, it will take all appropriate disciplinary or preventive action; and

• appropriate disciplinary or preventive action may include a letter of censure, suspension, dismissal or, in the event of criminal or other serious violations of law, notification of the Securities and Exchange Commission or other appropriate law enforcement authorities.

Waivers Of Code Of Ethics

Except as otherwise provided in this Code of Ethics, the CCO is responsible for applying this Code of Ethics to specific situations in which questions are presented to the CCO and has the authority to interpret this Code of Ethics in any particular situation. The CCO shall take all action he or she considers appropriate to investigate any actual or potential violations reported under this Code of Ethics.

Revised: July 30, 2014

The CCO is authorized to consult, as appropriate, with counsel to the affected Company, the Advisory Group or the Independent Directors, and is encouraged to do so.

The Board of Directors of the affected Company is responsible for granting waivers of this Code of Ethics, as appropriate. Any changes to or waivers of this Code of Ethics will, to the extent required, be disclosed on Form N-CSR, or otherwise, as provided by Securities and Exchange Commission rules.

Recordkeeping

Each Company will maintain and preserve for a period of not less than six (6) years from the date an action is taken, the first two (2) years in an easily accessible place, a copy of the information or materials supplied to the Boards of Directors pursuant to this Code of Ethics:

• that provided the basis for any amendment or waiver to this Code of Ethics; and

• relating to any violation of this Code of Ethics and sanctions imposed for such violation, together with a written record of the approval or action taken by the relevant Board of Directors.

Confidentiality

All reports and records prepared or maintained pursuant to this Code of Ethics shall be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code of Ethics, such matters shall not be disclosed to anyone other than the Independent Directors and their counsel, the Companies and their counsel, the Advisory Group and its counsel and any other advisors, consultants or counsel retained by the Directors, the Independent Directors or any committee of Directors.

Amendments

This Code of Ethics may not be amended as to any Company except in written form, which is specifically approved by a majority vote of the affected Company’s Directors, including a majority of its Independent Directors.

No Rights Created

This Code of Ethics is a statement of certain fundamental principles, policies and procedures that govern each of the Senior Officers in the conduct of the Companies’ business. It is not intended to and does not create any rights in any employee, investor, supplier, competitor, shareholder or any other person or entity.
