(a) RETURNS REPRESENT PAST PERFORMANCE AND DO NOT GUARANTEE FUTURE RESULTS. TOTAL RETURNS AND AVERAGE ANNUAL RETURNS REFLECT CHANGES IN SHARE PRICE AND 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. PERFORMANCE RETURNS FOR PERIODS LESS THAN ONE YEAR ARE NOT ANNUALIZED. 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. INVESTORS SHOULD CAREFULLY CONSIDER THE INVESTMENT OBJECTIVES, RISKS, CHARGES, AND EXPENSES OF THE FUND BEFORE INVESTING. THE PROSPECTUS CONTAINS MORE INFORMATION ABOUT THIS AND OTHER MATTERS AND SHOULD BE READ CAREFULLY BEFORE INVESTING. THE CLASS AAA SHARE NAVS PER SHARE ARE USED TO CALCULATE PERFORMANCE FOR THE PERIODS PRIOR TO THE ISSUANCE OF CLASS A SHARES, CLASS B SHARES, AND CLASS C SHARES ON DECEMBER 31, 2003 AND CLASS I SHARES ON JANUARY 11, 2008. THE ACTUAL PERFORMANCE OF THE CLASS B SHARES AND CLASS C SHARES WOULD HAVE BEEN LOWER DUE TO THE ADDITIONAL 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 S&P 500 INDEX AND THE RUSSELL 1000 GROWTH INDEX ARE UNMANAGED INDICATORS OF STOCK MARKET PERFORMANCE. DIVIDENDS ARE CONSIDERED REINVESTED. YOU CANNOT INVEST DIRECTLY IN AN INDEX. (b) INCLUDES THE EFFECT OF THE MAXIMUM 5.75% SALES CHARGE AT THE BEGINNING OF THE PERIOD.

THE GAMCO GROWTH FUND DISCLOSURE OF FUND EXPENSES (UNAUDITED) For the Six Month Period from January 1, 2008 through June 30, 2008 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.

See accompanying notes to financial statements. 8 THE GAMCO GROWTH FUND NOTES TO FINANCIAL STATEMENTS (UNAUDITED) 1. ORGANIZATION. The GAMCO Growth Fund (the "Fund") was organized on October 24, 1986 as a Massachusetts business trust. The Fund is a diversified open-end management investment company registered under the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund's primary objective is capital appreciation. The Fund commenced investment operations on April 10, 1987. 2. SIGNIFICANT ACCOUNTING POLICIES. The preparation of financial statements in accordance with 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 of Trustees (the "Board") so determines, by such other method as the Board shall determine in good faith to reflect its fair market value. Portfolio securities traded on more than one national securities exchange or market are valued according to the broadest and most representative market, as determined by Gabelli Funds, LLC (the "Adviser"). Portfolio securities primarily traded on 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 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 9 THE GAMCO GROWTH FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) - 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: INVESTMENTS IN SECURITIES VALUATION INPUTS (MARKET VALUE) -------------- Level 1 - Quoted Prices $ 784,429,355 Level 2 - Other Significant Observable Inputs 28,746,690 -------------- TOTAL $ 813,176,045 ============== 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. 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. SECURITIES TRANSACTIONS AND INVESTMENT INCOME. Securities transactions are accounted for on the trade date with realized gain or loss on investments determined by using the identified cost method. Interest income (including amortization of premium and accretion of discount) is recorded on the accrual basis. Premiums and discounts on debt securities are amortized using the effective yield to maturity method. Dividend income is recorded on the ex-dividend date except for certain dividends which are recorded as soon as the Fund is informed of the dividend. DETERMINATION OF NET ASSET VALUE AND CALCULATION OF EXPENSES. Certain administrative expenses are common to, and allocated among, various affiliated funds. Such allocations are made on the basis of each Fund's average net assets or other criteria directly affecting the expenses as determined by the Adviser pursuant to procedures established by the Board. 10 THE GAMCO GROWTH FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) In calculating the net asset value ("NAV") per share of each class, investment income, realized and unrealized gains and losses, redemption fees, and expenses other than class specific expenses are allocated daily to each class of shares based upon the proportion of net assets of each class at the beginning of each day. Distribution expenses are borne solely by the class incurring the expense. CUSTODIAN FEE CREDITS 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 equal to 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 shareholders if any are recorded on the ex-dividend date. Distributions to shareholders are based on income and capital gains as determined in accordance with federal income tax regulations, which may differ from income and capital gains as determined under U.S. generally accepted accounting principles. These differences are primarily due to differing treatments of income and gains on various investment securities held by the Fund, timing differences, and differing characterizations of distributions made by the Fund. 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. No distributions were made during the fiscal year ended December 31, 2007. PROVISION FOR INCOME TAXES. The Fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"). It is the policy of the Fund to comply with the requirements of the Code applicable to regulated investment companies and to distribute substantially all of its net investment company taxable income and net capital gains. Therefore, no provision for federal income taxes is required. At December 31, 2007, the Fund had net capital loss carryforwards for federal income tax purposes of $821,106,933, which are available to reduce future required distributions of net capital gains to shareholders. $469,914,764 is available through 2010; $350,050,494 is available through 2011; and $1,141,675 is available through 2012. The following summarizes the tax cost of investments and the related unrealized appreciation/(depreciation) at June 30, 2008: GROSS GROSS UNREALIZED UNREALIZED NET UNREALIZED COST APPRECIATION DEPRECIATION APPRECIATION ------------- ------------ -------------- -------------- Investments ... $ 772,541,340 $ 97,224,774 $ (56,590,069) $ 40,634,705 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. 11 THE GAMCO GROWTH FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) 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 Trustees of the Fund who are affiliated persons of the Adviser. The Fund pays each Trustee who is not considered to be an affiliated person an annual retainer of $6,000 plus $1,000 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 Chairmen of the Audit Committee, Proxy Voting Committee, and the Lead Trustee receive an annual fee of $1,000. Trustees 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. Gabelli & Company, Inc. ("Gabelli & Company"), an affiliate of the Adviser, serves as distributor of the Fund. Under the Class AAA, Class A, Class B, and Class C Share Plans, payments are authorized to Gabelli & Company at annual rates of 0.25%, 0.25%, 1.00%, and 1.00%, respectively, of the average daily net assets of those classes, the annual limitations under each Plan. Such payments are accrued daily and paid monthly. 5. PORTFOLIO SECURITIES. Purchases and proceeds from the sales of securities for the six months ended June 30, 2008, other than short-term securities and U.S. Government obligations, aggregated $289,355,251 and $342,046,434, 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 $20,591,656 and $23,888,675, respectively. 6. TRANSACTIONS WITH AFFILIATES. During the six months ended June 30, 2008, the Fund paid brokerage commissions on security trades of $14,600 to Gabelli & Company. Additionally, Gabelli & Company informed the Fund that it received $6,275 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 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. 7. LINE OF CREDIT. The Fund participates in an unsecured line of credit of up to $75,000,000, and may borrow up to 10% of its net assets from the custodian for temporary borrowing purposes. Borrowings under this arrangement bear interest at 0.75% above the federal funds rate on outstanding balances. This amount, if any, would be shown as "interest expense" in the Statement of Operations. During the six months ended June 30, 2008, there were no borrowings under the line of credit. 12 THE GAMCO GROWTH FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) 8. SHARES OF BENEFICIAL INTEREST. The Fund offers five classes of shares - Class AAA Shares, Class A Shares, Class B Shares, Class C Shares, and Class I Shares. Class AAA Shares and Class I Shares are offered to investors without a front-end sales charge. Class A Shares are subject to a maximum front-end sales charge of 5.75%. Class B Shares are subject to a contingent deferred sales charge ("CDSC") upon redemption within six years of purchase and automatically convert to Class A Shares approximately eight years after the original purchase. The applicable CDSC is equal to a declining percentage of the lesser of the NAV per share at the date of the original purchase or at the date of redemption, based on the length of time held. Class C Shares are subject to a 1.00% CDSC for one year after purchase. Class B Shares are available only through exchange of Class B Shares of other funds distributed by Gabelli & Company. Class I Shares were first issued on January 11, 2008. The Fund imposes a redemption fee of 2.00% on all classes of shares that are redeemed or exchanged on or before the seventh day after the date of a purchase. The redemption fee is deducted from the proceeds otherwise payable to the redeeming shareholders and is retained by the Fund. The redemption fees retained by the Fund during the six months ended June 30, 2008 and the fiscal year ended December 31, 2007 amounted to $837 and $2,333, respectively. The redemption fee does not apply to redemptions of shares where (i) the shares were purchased through automatic reinvestment of distributions, (ii) the redemption was initiated by the Fund, (iii) the shares were purchased through programs that collect the redemption fee at the program level and remit them to the Fund, or (iv) the shares were purchased through programs that the Adviser determines to have appropriate anti-short-term trading policies in place or as to which the Adviser has received assurances that look-through redemption fee procedures or effective anti-short-term trading policies and procedures are in place. Transactions in shares of beneficial interest were as follows: SIX MONTHS ENDED JUNE 30, 2008 YEAR ENDED (UNAUDITED) DECEMBER 31, 2007 ------------------------------ ------------------------------------ SHARES AMOUNT SHARES AMOUNT ------------- -------------- ----------------- ---------------- CLASS AAA CLASS AAA Shares sold.......... 902,643 $ 29,958,552 1,554,938 $ 52,014,192 Shares redeemed......

INDEMNIFICATIONS. The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 10. OTHER MATTERS. 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. 14 THE GAMCO GROWTH FUND BOARD CONSIDERATION AND RE-APPROVAL OF INVESTMENT ADVISORY AGREEMENT (UNAUDITED) At its meeting on February 27, 2008, the Board of Trustees ("Board") of the Fund approved the continuation of the investment advisory agreement with the Adviser for the Fund on the basis of the recommendation by the trustees 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 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 long-term performance of the Fund against a peer group of large cap growth funds chosen by Lipper as being comparable. The Independent Board Members noted that the Fund's performance was in the top one-third of the funds in its category for the one, three, and five year periods. PROFITABILITY. The Independent Board Members reviewed summary data regarding the profitability of the Fund to the Adviser both with an administrative overhead charge and without such a charge. The Independent Board Members also noted that a small portion of the Fund's portfolio transactions were executed by an affiliated broker and that the affiliated broker received distribution fees and minor amounts of sales commissions. The Independent Board Members also noted that a 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, and 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. SHARING OF ECONOMIES OF SCALE. The Independent Board Members noted that the investment advisory fee schedule for the Fund does not take into account any potential economies of scale that may develop. 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 to similar expense ratios of the peer group of large-cap growth 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 and the Fund's size were above average within this group. The Independent Board Members also noted that the advisory fee structure was the same as that in effect for most of the Gabelli funds. The Independent Board Members were presented with, but did not consider to be material to their decision, various information comparing the advisory fee to the fee for other types of accounts managed by affiliates of the Adviser. CONCLUSIONS. The Independent Board Members concluded that the Fund enjoyed highly experienced portfolio management services, good ancillary services, and a good performance record. The Independent Board Members also concluded that the Fund's expense ratios and the profitability to the Adviser of managing the Fund were reasonable in light of the Fund's performance and that economies of scale were not a significant factor in their thinking at this time. 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 advisory agreement to the full Board. 15 THE GAMCO GROWTH FUND One Corporate Center Rye, New York 10580-1422 800-GABELLI 800-422-3554 FAX: 914-921-5118 WEBSITE: www.gabelli.com E-MAIL: info@gabelli.com Net Asset Value per share available daily by calling 800-GABELLI after 6:00 P.M.
