Dear Fellow Shareholder: December 28, 2006

The Caldwell & Orkin Market Opportunity Fund (the “Fund”) gained 4.31% in the 6-month period ended October 31, 2006. For the 12 months ended October 31, 2006, the Fund rose 1.17%. And, since commencement of active management on August 24, 1992 through October 31, 2006, the Fund generated a 9.80% average annual return while maintaining a low market risk profile and with little reliance upon the movement of the stock market (see pages 4, 5 and 6). Of course, past performance is no guarantee of future results.

Since we began actively managing the Fund on August 24, 1992, the Fund’s price movements have correlated very little (2.89%) with the price movements of the S&P 500 with Income index (S&P 500). The Fund’s beta (a measure of volatility) is -0.08. An S&P 500 index fund has a 100% correlation to the market and a beta of 1.00. The Fund’s lack of correlation to the market indicates that its performance is not attributable to that of the index. (Statistical computations by Ned Davis Research, Inc.)

Management Discussion and Analysis

The Market Opportunity Fund opened the six-month review period on May 1, 2006 positioned 53.26% long, -40.31% short and 6.43% in cash and cash equivalents, resulting in a 12.95% net long exposure. Our largest long sector exposure was to select biomedical and biotechnology companies. These investments represented opportunities tied to the fortunes of the compounds or technologies unique to these companies. We also held limited short exposure to the sector dependent on a given company’s prospects. Our largest short exposure was to the market itself through exchange-traded funds (ETFs), followed by mortgage related finance companies and residential and commercial builders. For quite some time we have been watching the housing bubble inflate, and these companies stood to lose ground during the deflating process, particularly in the financing sector, which is vulnerable to rising credit losses.

We maintained our slightly net long positioning during early May (see the Equity Investment Position chart on page 6), then shifted to net short in mid-May as the markets started deteriorating. Inflation fears ignited by continued high energy and commodity costs, and evidence that those higher costs were permeating through the economy, spooked investors who feared that the Federal Reserve would continue its campaign of raising interest rates. In addition, central banks around the world shifted into a hawkish mode by raising interest rates. This global tightening drained liquidity from the financial markets, resulting in falling stock prices.

The shorts did well in May. From the S&P 500’s high on May 5, 2006 through month-end, the short portfolio returned 4.80%, versus a -4.08% loss for the S&P 500. Our higher beta longs, however, which are more sensitive to market volatility, got hit harder than the general market during the earliest days of the market’s decline. The risk profile of the longs was reduced shortly

after the initial setback by selling higher beta stocks. For the full month the Fund slipped - -1.02%, compared to losses of -2.93% and -6.19% for the S&P and NASDAQ, respectively.

We exited May -9.5% net short, and in June adjusted the asset allocation to take advantage of the falling market. By mid-June the Fund was almost -32% net short. The Fund rose 1.82% during June, while the S&P 500 gained 0.15% and the NASDAQ fell -0.31%. At its June 28 meeting, the Fed announced another 0.25% hike in interest rates, but also signaled a pause may be in order. Anticipating a less hawkish Fed, we had already reverted back to a market neutral posture before the Fed’s announcement was released. We closed the quarter 99.2% invested and 1.2% net long.

The market started off on a positive note in July, coming on the heels of a late Q2-end rally. We held S&P 500 Depositary Receipts (SPY) and NASDAQ-100 Shares (QQQQ), both exchange-traded funds, which gave us broad exposure to the rising market. Builders and mortgage & related financial services companies topped the short sector exposure. The rally fizzled a few days into July, and we went back to a net-short tack. The Fund, propelled by the shorts, rose 2.08% in July, compared to a 0.66% gain for the S&P 500 and a loss of -3.71% for the NASDAQ.

The markets turned back up in mid August after the Federal Reserve passed over an opportunity to raise the Fed Funds rate. We shifted from a net short to a net long position, and covered all the homebuilding shorts. We stuck with the subprime mortgage-centric lender shorts, shorted restaurants, and beefed-up our electric utility longs. The moves were advantageous, as the longs rose 2.57% and the shorts declined only -0.16%. The portfolio returned 1.22% in August, compared to a 2.30% rise for the S&P 500. We closed the month 98.5% invested and 6.2% net long. During September, declines in energy prices gave the market traction, and we reined in more shorts while adding to long positions, including technology exposure due to improving fundamentals. The longs did well in September, rising 3.69%, but the shorts took a beating, declining -8.44%. Fortunately, they represented a smaller slice of the overall portfolio. For the month, the Fund dipped -0.69% compared to a 2.60% rise in the S&P 500.

We opened October 94.1% invested and 31.2% net long. Falling energy prices and a generally positive market climate gave the market additional traction. The Fund rose 0.87% for the month, and the S&P was up 3.33%. We closed the review period positioned 61.96% long, -25.89% short (36.07% net long), 9.66% in U.S. Treasury Bills and 2.49% in cash and cash equivalents.

Outlook

The market continues to move forward. Energy prices remain tempered (though high by historical standards they are down from their peaks, and are thus viewed by consumers as acceptable), and corporate merger and acquisition activity has increased. We’ve maintained our net long asset allocation and as of the date of this letter the Fund is positioned 37.98% net long.

As our Shareholders know, we’ve been keenly tracking the subprime mortgage sector for quite some time. While our shorts in the sector were early, (we were swimming against a tide of liquidity unleashed by the Fed, which in our view only exacerbated the problem), our conviction and diligence to the general themes of the over-extended consumer and a housing bubble (which merge with subprime mortgage lending) are now paying off. Lately, many such companies have been in the news, and not because they wanted to be there or because they want to consolidate all your debts into one easy payment (no equity and no income verification required).

We recently asked Ned Davis Research, Inc. how long it has been since the last 10% decline in the S&P 500. The answer: over 3.5 years — the last 10% drop ended March 11, 2003. Between May 14, 1928 and November 27, 2002 (the start of the last decline), the stock market has averaged a 10% correction every seven months. Over the last 10-years, a 10% correction has occurred every 12 months, still a far cry from the 3.5 year “safe zone.” This does not mean we will have a 10% correction any time soon, but it does suggest that investors should be wary. We are.

Postscript

The Fund’s Annual Meeting of Shareholders was reconvened on November 3, 2006, and the results of the Fund’s Proxy vote were tallied and reported. We are pleased to announce that all proposals put before Shareholders passed. To date, we have made only one change based on the investment restriction amendments approved by Shareholders. On November 17, 2006 we began investing in options, since former Investment Restriction No. 14 (which prohibited the Fund from investing in options) was deleted. More specifically, we began purchasing put options. Like short sales, put options allow us to capitalize on falling share prices (or a falling market), and give us another tool to use to hedge both stock and market risk. There are, or course, risks involved with using options. Those risks are addressed in the Supplement to the Fund’s Statement of Additional Information dated November 7, 2006, which is available on the Fund’s website, www.CaldwellOrkin.com, or by calling the Fund at 800-237-7073. We have no plans to implement any of the other changes that were approved.

On behalf of all of us at Caldwell & Orkin, I wish you and your families a happy and healthy New Year, and I thank you for your continued support.

Sincerely,

Michael B. Orkin, CFA
Portfolio Manager and Chief Investment Officer

The Fund’s investment objective is to provide long-term capital growth with a short-term focus on capital preservation. We use active asset allocation — the opportunistic shifting of assets between long stock positions, short stock positions (selling borrowed stock and attempting to replace the borrowed securities in the future at a lower price), bonds and cash equivalents — to manage exposure to market risk (the risk that the broad market declines, taking good companies down with it). Short positions are taken with the intent of making money when those stocks we judge to be overvalued fall. In addition to the above investment instruments and subsequent to the Annual Meeting of Shareholders which was reconvened on November 3, 2006, we have also begun to use options, specifically the purchase of put options. The first puts were purchased on November 17, 2006. Additional information on our use of options is included in the Postscript section of this letter.

Importantly, one of the risks of a long / short (or hedged) investment approach is that the Fund may lose money in a rising stock market since short positions and put options generally decline in value as the market rises. A disciplined investment process emphasizing both fundamental research and technical analysis is used to manage stock risk (the risk that a stock underperforms due to company-specific reasons).

An investment in the Fund involves many other risks in addition to those mentioned above. For a complete discussion of these risks, as well as the expenses associated with investing in the Fund, please request a copy of the Fund’s Prospectus by calling (800) 237-7073. In summary, our goal is to make money over a full market cycle, but with less stomach churn.

The performance data quoted represents past performance. Past performance does not predict future performance, and does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. The investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Current performance may be higher or lower than the performance data quoted. To obtain performance information current to the most recent month-end, please call (800) 237-7073. Fund holdings, industry and asset allocations are subject to change without notice. The Fund’s performance assumes the reinvestment of income, dividend and capital gain distributions, if any.

1	Performance figures represent past performance and do not indicate future results. The returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. See additional performance disclosure on page 3.
2	The S&P 500 with Income index (“S&P 500”) is a widely recognized unmanaged index of U.S. Stocks. The S&P 500 figures do not reflect any fees or expenses, nor do they reflect the use of short positions. There is no unmanaged index currently available which reflects the use of both long and short positions. We cannot predict the Fund’s future performance, but we expect that our investment strategy, which includes the use of short sales, will cause the Fund’s performance to fluctutate independently from the S&P 500. While the portfolio is hedged, our stategy may prevent the Fund from participating in market advances, yet it may offer the Fund downside protection during market declines.
3	Effective August 24, 1992, the Caldwell & Orkin Market Opportunity Fund changed its investment objective to provide long-term capital growth with a short-term focus on capital preservation through investment selection and asset allocation. Prior to that time, the Fund was passively managed and indexed to the largest 100 over-the-counter (OTC) stocks.

CALDWELL & ORKIN MARKET OPPORTUNITY FUND

DISCLOSURE OF FUND EXPENSES (UNAUDITED)

We believe it is important for you to understand the impact of fees and expenses on your investment in the Caldwell & Orkin Market Opportunity Fund. As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees and brokerage commissions (if applicable); and (2) ongoing costs, including management fees, dividend expenses on securities sold short, and other Fund expenses (“operating expenses”). All mutual funds have operating expenses. Operating expenses are deducted from a fund’s gross income, and directly reduce the investment return of the Fund. A fund’s operating expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following example is intended to help you understand your ongoing costs (in dollars and cents) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The below example is based on an investment of $1,000.00 invested at the beginning of the period and held for the entire period indicated, May 1, 2006 through October 31, 2006. The table below illustrates the Fund’s expenses in two ways:

Based on Actual Fund Returns

The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Based on a Hypothetical 5% Return for Comparison Purposes

The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare 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 the shareholder reports of the 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 redemption fees or brokerage commissions. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

					Annualized			Expenses Paid
	Beginning Account		Ending Account		Expense			During Period *
	Value 5/1/2006		Value 10/31/2006		Ratio			5/1/2006-10/31/2006
Actual Fund Return	$	1,000.00	$	1,043.10		1.60	%	$	8.24
Hypothetical 5% Annual	$	1,000.00	$	1,017.14		1.60	%	$	8.13
Return before expenses

* Expenses are equal to the Fund’s annualized expense ratio of 1.60%, multiplied by the average account value over the period, multiplied by 184, and divided by 365 (to reflect the one-half year period).

CALDWELL & ORKIN MARKET OPPORTUNITY FUND

NOTES TO FINANCIAL STATEMENTS

October 31, 2006 (Unaudited)

The Caldwell & Orkin Market Opportunity Fund (the “Fund”) is the only active investment portfolio of The Caldwell & Orkin Funds, Inc. (“Caldwell & Orkin”), an open-end, diversified management investment company registered under the Investment Company Act of 1940, as amended, and incorporated under the laws of the State of Maryland on August 15, 1989. Prior to June, 1992, Caldwell & Orkin’s name was The OTC Select-100 Fund, Inc. and consisted of only one portfolio, The OTC Select-100 Fund. The shareholders of The OTC Select-100 Fund subsequently approved changing the corporate name from The OTC Select-100 Fund, Inc. to The Caldwell & Orkin Funds, Inc. and to amend the investment objective and policies of The OTC Select-100 Fund. As a result of such amendment, The OTC Select-100 Fund was renamed and its assets and objectives were those of the Caldwell & Orkin Aggressive Growth Fund. In August, 1996, the Board of Directors of Caldwell & Orkin approved changing the name of the Caldwell & Orkin Aggressive Growth Fund to the Caldwell & Orkin Market Opportunity Fund. The Fund’s objectives are to provide long-term capital growth with a short-term focus on capital preservation through investment selection and asset allocation. The Fund seeks to outperform the stock market over the long-term, as measured by indices such as the S&P 500 with Income.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Securities Valuation

Securities are stated at the closing price on the date at which the net asset value (“NAV”) is being determined. If the date of determination is not a trading date, the last bid price is used for a value instead. Short-term investments having a maturity of 60 days or less at the time of the purchase are stated at amortized cost, which approximates market value. Any assets or securities for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Fund’s Board of Directors in accordance with the Fund’s Fair Value Pricing Policy.

Share Valuation

The NAV per share of the Fund is calculated by dividing the sum of the value of the securities held by the Fund, plus cash or other assets, minus all liabilities (including estimated accrued expenses) by the total number of shares outstanding for the Fund, rounded to the nearest cent. The Fund’s shares will not be priced on the days on which the New York Stock Exchange is closed for trading. The offering and redemption price per share for the Fund is equal to the Fund’s NAV per share. The Fund charges a 2.00% redemption fee on shares held less than six months. These fees are deducted from the redemption proceeds otherwise payable to the shareholder. The Fund will retain the fee charged as paid-in capital and such fees become part of the Fund’s daily NAV calculation.

Securities Transactions And Related Investment Income

Securities transactions are accounted for on trade date. Dividend income is recorded on the ex-dividend date and interest income is recorded as earned. Realized gains and losses from investment transactions are determined using the specific identification method.

Cash

The Fund maintains cash available for the settlement of securities transactions and capital shares reacquired. Available cash is invested daily in money market instruments.

NOTES TO FINANCIAL STATEMENTS – (Continued)

October 31, 2006 (Unaudited)

Income Taxes

The Funds intend to continue to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all taxable income to their shareholders. Therefore, no federal income tax provision is required.

At April 30, 2006, the Caldwell & Orkin Market Opportunity Fund had a net capital loss carryforward of $26,128,760, of which $22,081,637 expires in 2011 and $4,047,123 expires 2014. This amount will be available to offset like amounts of any future taxable gains through the respective expiration periods. At April 30, 2006, the Fund deferred, on a tax basis, post-October losses of $2,835,450, which will be recognized in the following year.

For the year ended April 30, 2006, the Fund made a distribution of $0.1874 per share from ordinary income. No distribution was made from capital gains.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

2.

COMMITMENTS AND OTHER RELATED PARTY TRANSACTIONS

The Fund has entered into a management agreement with C&O Funds Advisor, Inc. (the “Adviser”) pursuant to which the Adviser provides space, facilities, equipment and personnel necessary to perform administrative and investment management services for the Fund. The management agreement provides that the Adviser is responsible for the actual management of the Fund’s portfolio. For such services and expenses assumed by the Adviser, the Fund pays a monthly advisory fee at incremental annual rates as follows:

	The Fund has entered into a distribution agreement with IFS Fund Distributors, Inc. (the “Distributor”) pursuant to which the Distributor provides broker/dealer services for the Fund. The Distributor is responsible for the sales and redemptions of the Fund’s shares. The Distributor does not charge the Fund for these services.
	C&O Funds Advisor, Inc. is a wholly-owned subsidiary of Caldwell & Orkin, Inc. IFS Fund Distributors, Inc. and Integrated Investment Services, Inc. (the Fund’s transfer, redemption and dividend disbursing agent) are affiliates by reason of common ownership.
3.	INVESTMENT PORTFOLIO TRANSACTIONS

Investment Purchases and Sales

For the six months ended October 31, 2006, purchases of investments and proceeds from sales of investments (excluding securities sold short and short-term investments) totaled $206,154,720,and $202,081,899 respectively.

Short Sales and Segregated Cash

Short sales are transactions in which the Fund sells a security it does not own, in anticipation of a decline in the market value of that security. To initiate such a transaction, the Fund must borrow the security to deliver to the buyer upon the short sale; the Fund is then obligated to replace the security borrowed by purchasing it in the open market at some later date, completing the transaction.

The Fund will incur a loss if the market price of the security increases between the date of the short sale and the date on which the Fund replaces the borrowed security. The Fund will realize a gain if the security declines in value between those dates.

All short sales must be fully collateralized. The Fund maintains the collateral in segregated accounts consisting of cash and/or U.S. Government securities sufficient to collateralize the market value of its short positions. Typically, the segregated cash with brokers and other financial institutions exceeds the minimum required. Deposits with brokers for securities sold short are invested in money market instruments.

The Fund may also sell short “against the box”, i.e., the Fund enters into a short sale as described above, while holding an offsetting long position in the same security which it sold short. If the Fund enters into a short sale against the box, it will segregate an equivalent amount of securities owned by the Fund as collateral while the short sale is outstanding.

The Fund limits the value of its short positions (excluding short sales “against the box”) to 60% of the Fund’s total net assets. At October 31, 2006, the Fund had 26% of its total net assets in short positions.

For the six months ended October 31, 2006, the cost of investments purchased to cover short sales and the proceeds from investments sold short were $240,624,991 and $218,235,450, respectively.

7.	RECENT ACCOUNTING PRONOUNCEMENTS
	On July 13, 2006, the Financial Accounting Standards Board (“FASB”) released FASB Interpretation No. 48 “Accounting for Uncertainty in Income Taxes” (“FIN 48”). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 clarifies the accounting for income taxes, by prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. FIN 48 requires that a “more-likely-than-not” threshold be met before the benefit of a tax position may be recognized in the financial statements and prescribes how such benefit should be measured. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, Management is evaluating the implications of FIN 48 and its impact in the financial statements has not yet been determined.
	IN September 2006, FASB issued FASB Statement No. 157, “Fair Value Measurement” (“SFAS 157”), which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. Management believes the adoption of SFAS 157 will not have a material impact on the Fund’s financial position or results of operations.

CALDWELL & ORKIN MARKET OPPORTUNITY FUND
DIRECTOR APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT (unaudited)

The Board of Directors of The Caldwell & Orkin Funds, Inc. (the “Board”) is responsible for overseeing management of the Caldwell & Orkin Market Opportunity Fund (the “Fund”). As required by law, on an annual basis the Board determines whether to continue the Fund’s Investment Advisory Agreement (the “Agreement”) with C&O Fund Advisors, Inc. (the “Adviser”), the manager of the Fund.

The Board met in person at the office of Caldwell & Orkin, Inc., Norcross, Georgia on June 21, 2006 to discuss, among other agenda items, renewal of the Agreement between the Fund and the Adviser. Prior to the meeting, the Directors that are not “interested persons” of the Fund (the “Independent Directors”) and their independent legal counsel requested and received (i) a memorandum from Kilpatrick Stockton LLP (legal counsel to the Adviser) regarding the issues and legal standards the Board should consider in evaluating whether to renew the Agreement between the Fund and the Adviser; and (ii) a memorandum from the Adviser to the Board which included, among other things, the Adviser’s Form ADV; information about the Fund’s personnel, policies and financial circumstances; data regarding the Fund’s performance record and the performance records of a universe of the Fund’s peers; and information about the Fund’s expense ratio and management fees, and the expense ratios, management fees and other expense of a universe of the Fund’s peers.

Prior to the general Board meeting, the Independent Directors and their independent legal counsel met in executive session to review the materials presented, and to discuss the investment management and administrative services provided by the Adviser to the Fund, the income and expenses of the Adviser related to the Fund and related information about the Fund.

In addition to meeting in executive session, the Independent Directors and their independent legal counsel also met with management of the Adviser in their consideration of the Agreement. Throughout the deliberation process, the Independent Directors were advised by their counsel.

As a part of their evaluation process, the Independent Directors considered various factors they determined to be relevant, including the material factors detailed below. None of the factors was a sole determining factor; rather, consideration of all the factors formed the basis for the Independent Directors’ decision. The material factors considered by the Independent Directors included, without limitation, the following:

(i)	The nature, extent, and quality of the services provided by the Adviser. In this regard, the Board reviewed the services being provided by the Adviser to the Fund including, without limitation, its investment advisory and administrative services since the Fund’s inception, its coordination of services and distribution efforts for the Fund over the years, and its provision of officers to the Fund (including the Fund’s chief compliance officer) without additional compensation. After reviewing the foregoing information, the Board concluded that the quality, extent and nature of the services provided by the Advisor was satisfactory and adequate for the Fund
(ii)	The investment performance of the Fund and Adviser. In this regard, the Board compared the performance of the Fund with the performance of benchmark index and comparable funds managed by other advisers. The Board also considered the consistency of the Adviser’s management of the Fund with the Fund’s investment objective and policies, and long-term performance of the Fund and the Adviser’s separate accounts. Following further discussion, the Board concluded that the investment performance of the Fund and Adviser was acceptable for purposes of consideration of the renewal of the Agreement.
(iii)	costs of the services to be provided and profits to be realized by the Adviser and its affiliates from the relationship with the Fund. In this regard, the Board considered the Adviser’s staffing, personnel and methods of operating; the financial condition of the Adviser and the level of commitment to the Fund and the Adviser by the principals of the Adviser; the asset levels of the Fund; and the overall expenses of the Fund. The Board noted the Fund’s expense limitation agreement with the Adviser and also considered potential benefits for the Adviser in managing the Fund, including promotion of the Adviser’s name, the ability for the Adviser to place small accounts into the Fund, and the potential for the Adviser to generate soft dollars from Fund

24

CALDWELL & ORKIN MARKET OPPORTUNITY FUND
DIRECTOR APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT (continued)

trades that may benefit the Adviser’s clients other than the Fund. The Board then compared the fees and expenses of the Fund (including the management fee) to other funds comparable to the Fund in terms of the type of fund, the style of investment management (including, in particular, the use of short selling as part of the Fund’s principal investment strategy) and the nature of the investment strategy and markets invested in, among other factors. The Board also discussed that the fees were generally lower than other funds employing long-short strategies and that the overall Fund expense ratio was satisfactory in light of the Fund’s objectives and strategies. Following this comparison and upon further consideration and discussion of the foregoing, the Board concluded that the fees to be paid to the Adviser by the Fund were fair and reasonable.

(iv)

The extent to which economies of scale would be realized as the Fund grows, and whether advisory fee levels reflect these economies of scale for the benefits of the Fund’s investors. In this regard, the Board considered the Fund’s fee arrangements with the Adviser, the Fund’s fee arrangements with other service providers, and the expense limits that are included in the Fund’s Investment Advisory Agreement. The Board considered the Fund’s fee level break points, and noted that shareholders benefit from economies of scale as the Adviser’s management fees are reduced as asset levels increase. Following further discussion of the Fund’s current asset levels and fee breakpoints, the Board determined that the Fund’s fee arrangements with the Adviser reflect economies of scale for the benefit of shareholders.

Based upon its evaluation of the information, materials and factors described above, the Directors, including all of the Independent Directors, concluded for the Fund: (i) that the terms (including, without limitation, the fees) of the Agreement were reasonable and fair in light of the nature and quality of services performed by the Advisor; (ii) that they were satisfied with the Adviser’s services, personnel and investment strategy; and (iii) that it was in the best interest of the Fund and its shareholders to renew the Agreement.

Approval of Amendment to the Investment Advisory Agreement

After the Board approved the renewal of the Agreement, the Board addressed the issue of amending the management fee, noting that the Fund’s management fee is lower than some of its relevant peers. The Board noted that the Fund is more labor intensive to run than many long-only funds, yet the Fund carries a lower management fee. After a discussion of the management fee and the Agreement, the Board noted that the Agreement was 13 years old and questioned whether it may need to be amended. The Board considered whether the CCO’s compensation, currently paid by the Adviser, should be partly paid by the Fund. The Board then discussed the appropriateness of having at least a portion of the CCO’s compensation under the complete control of the Board and payable by the Fund. The Board also discussed the extra cost that the new CCO requirements had placed on the Adviser, particularly given that the Adviser’s fees are already lower than some peer funds. The Board noted that per the terms of the current Agreement, the Adviser is responsible for paying all compensation of officers of the Fund who are affiliated persons of the Adviser, and, as an employee of the Adviser, he was technically an affiliate. The Fund’s counsel noted that any change to the Agreement to allow the Fund to pay a portion of the CCO’s compensation would require shareholder approval and that such an amendment could be included in an upcoming shareholder proxy vote. After extensive discussion, the Directors, including all of the Independent Directors, voted to approve an amendment to the Agreement that would allow a portion of the CCO’s compensation to be paid by the Fund.

The Board then directed Fund management to submit the amendment to the Agreement to the Fund’s shareholders for approval. The Fund’s shareholders approved the amendment to the Agreement to allow a portion of the CCO’s compensation to be paid by the Fund in a shareholder meeting that commenced on October 4, 2006 and reconvened on November 3, 2006.
