Item 4: Advisory business Services

ACK Asset Management LLC (“ACKAM”) has been in business since 2005. ACKAM serves as the investment adviser to ACK Asset Partners LP and ACK Asset Partners (Cayman) Ltd, both of which invest their assets in ACK Asset Master Fund LP, as well as the investment adviser to ACK Asset Partners II, LP. Collectively, these private funds are referred to as “Private Funds” or “Clients” herein. ACK Asset GP II LLC (“ACK GP”), an affiliate of ACKAM, serves as the general partner of the private funds that are organized as limited partnerships. ACKAM and ACK GP are collectively referred to as “ACK” or the “Adviser” throughout this brochure. ACK provides investment advisory services to the Private Funds based on the investment objectives described in their offering documents and does not tailor investment advice to individual investors. The Private Funds are neither registered under the Securities Act of 1933, as amended, nor registered under the Investment Company Act of 1940, as amended. Accordingly, interests in the Private Funds are offered exclusively to investors satisfying the applicable eligibility and suitability requirements either in private placement transactions within the United States or in certain offshore jurisdictions. The firm is owned by Richard S. Meisenberg and John H. Reilly III, Managing Members. As of December 31,2025, ACK managed discretionary client assets valued at approximately $1,068,346,088. ACK does not manage assets on a non-discretionary basis.

Item 5: Fees and compensation Fees

ACK typically charges investors in the Private Funds a management fee that ranges between 1.00% and 1.50% per annuum of the assets under management depending on when investors initially invested in a respective Private Fund and subject to fee caps as described in the Private Fund’s offering documents. The management fee is paid quarterly in advance based on the balance of each investors account as of the beginning of each quarter. ACK is also eligible to earn performance-based compensation (“incentive allocation”) in the amount of 20% of annual net profits of each Private Fund attributable at the Investor level, subject to a loss recovery mechanism as discussed in each respective Private Funds offering documents. ACKAM or the General Partner may, in their sole discretion, waive or reduce the fee to fund investors who are members, principals, employees or affiliates of ACK, relatives of such persons and certain large or strategic investors and have done so on occasion. The Private Funds have entered into agreements (“Side Letters”) with certain investors that result in different terms of an investment in the Private Fund than the terms applicable to other investors including, but not limited to, rights to receive reduced management and incentive fees or additional reports and enhanced disclosure of certain events. As a result of such Side Letters, certain investors have received additional benefits which other investors do not receive. Such agreements are entered into by such investors without the consent of other investors in such Private Funds; additionally, except as may be required by “most-favored-nations” clauses, such agreements usually need not be disclosed to other investors. Client assets invested in money market funds managed by independent managers, including funds at custodian banks, broker-dealers or other custodians, may be subject to management fees, trading costs and other expenses charged by the manager of these funds which are in addition to management fees charged by the Adviser. ACK’s fees are exclusive of the Private Funds operating and other expenses including (without limitation): investment expenses (e.g., expenses which the Adviser determines to be related to the investment of a Private Fund’s capital, such as brokerage commissions, clearing and settlement charges, bank service fees and interest expenses), custodial fees, legal expenses, ongoing offering expenses, internal and external accounting expenses, auditing and tax preparation expenses, custodial and prime brokerage expenses, premiums for liability insurance covering the Private Funds, the Adviser and their respective agents, fees

and expenses of the Administrator, fees and out-of-pocket expenses of any service company retained to provide fund accounting, bookkeeping and administrative services. To the extent that expenses to be borne by the Partnership are paid by the Investment Manager, the Investment Manager will be reimbursed by the Partnership for such expenses.

Item 8: Methods of analysis, investment strategies and risk of loss Investment strategies and risks

Investing in securities involves risk of loss that clients should be prepared to bear. ACK advises clients pursuant to a long/short equity strategy focused on small and mid-capitalization stocks with the potential to deliver significant capital appreciation and strong absolute returns with strong capital preservation characteristics. These descriptions of strategies which ACK may use should not be understood as limiting ACK’s investment activities. ACK may engage in investment strategies for its client accounts not described here that ACK considers consistent with clients’ overall investment program. Client investment programs may be speculative and entail substantial risks. There can be no assurance that the investment objectives will be achieved or that investment results might not vary substantially on a monthly, quarterly, or annual basis. Certain investment practices can, in certain circumstances, increase the adverse impact to which client’s portfolios may be subject to. ACK looks for fundamental changes in companies and catalysts that can drive growth. ACK monitors the macroeconomic environment to identify secular and cyclical trends that can drive long and short opportunities in certain sectors and industries in the economy. Valuation is a key part of the investment equation in both the long and short side of ACK’s managed portfolios. The short side is managed to add both alpha to the overall portfolio and serve as a hedge during down markets. The Adviser believes that the small capitalization segment of the United States stock market is relatively inefficient. Typically, small capitalization companies have limited sell-side research coverage. Since small capitalization companies outnumber their large cap counterparts by a ratio of more than 10-to-1, the Adviser believes there is often limited institutional analysis by buy-side firms. In aggregate, more than eighty percent of companies listed on New York Stock Exchange, American Stock Exchange, and the NASDAQ Stock Market fall into the bottom quintile in market capitalization. The Adviser believes there are many instances

of inefficiencies in the small capitalization segment because the major new money being invested in equities has gravitated towards larger, more liquid securities (issuers with market capitalizations of $1.5 billion or more). The Adviser feels this is especially true in areas where positive fundamental change has already occurred but is not evident in reported earnings, as well as in areas where there are steps in place for positive fundamental change to occur, which steps are not yet evident. The Adviser seeks to target companies with strong management teams that have experience in their fields and proven track records for success. The Adviser views company management teams as partners in investments and values insider ownership. The Adviser seeks to communicate its suggestions to company management and convey how such suggestions will impact their wealth. The Adviser expects to invest in companies that have high equity components for management compensation. The Adviser’s research process has a strong emphasis on free cash flow generation (“FCF”). In addition to balance sheet and income statement analysis, the Adviser will follow a company’s internal cash generation and the ways the company invests that cash for shareholder returns. The Adviser will typically use FCF yield as an important valuation metric and will generally build its own detailed earnings and cash flow models for its investments, creating bottom-up estimates utilizing publicly available information from management, customers, suppliers and competitors. The Adviser seeks to identify business models with high recurring revenue components, defendable niche businesses and pricing power in their markets. The Adviser recognizes that these “ideal” investments are rare and intends to concentrate investments in these opportunities when possible. The Adviser recognizes that timing of an investment is very important and intends to utilize money flows and identify catalysts to pick the entry price. While ACK will invest primarily in publicly traded equities on behalf of its client accounts, ACK may also invest in privately issued securities of both public and private companies including, from time to time, investment in privately issued securities of public companies (“PIPES”) that generally involve contractual obligations by the issuer to take certain actions such as registering the securities for resale. Material Risks. The list of risk factors below is not a complete enumeration or explanation of the risks involved in an investment through ACK or any of the client portfolios it manages. For investors or potential investors in Private Funds managed by ACK, refer to the private placement memorandum and other Private Fund documents, such as the limited partnerships agreement, for a complete description of risks associated with the Private Fund(s). Trading in Small and Mid-Capitalization Markets. ACK invests in the stocks of small and midcapitalization companies. The earnings and prospects of these companies are generally more volatile than larger companies. Small and mid-capitalization companies may experience higher failure rates than do larger companies. While ACK believes they often provide significant potential for appreciation, such stocks, particularly smaller-capitalization stocks, involve higher risks in some respects than do investments in stocks of larger companies. For example, prices of such stocks are often more volatile than prices of largecapitalization stocks. In addition, due to thin trading in some such stocks, an investment in these stocks may be more illiquid than that of larger capitalization stocks. The trading volume of the securities of these companies is normally less than that of larger companies and, therefore, may disproportionately affect their market price, tending to make them fall more in response to selling pressure than is the case with larger companies. These securities entail more risk (and potentially more benefit) than investments in shares of companies with higher market capitalizations because of market conditions in general, especially in times of market volatility and illiquidity. In addition, failed expectations concerning particular industries or companies and negative analyst comments could have a relatively dramatic effect on the prices of these securities. High Growth Industry Related Risks. ACK may invest its client assets in high growth companies, which may allocate, or may have allocated, greater than usual amounts to research and product development. The securities of such companies may experience above-average price movements associated with the perceived prospects of success of the research and development programs. In addition, these companies could be adversely affected by lack of commercial acceptance of a new product or products or by technological change and obsolescence. Some of these companies may have limited operating histories.

As a result, these companies may face undeveloped or limited markets, have limited products, have no proven profit-making history, may operate at a loss or with substantial variations in operating results from period to period, have limited access to capital and/or be in the developmental stages of their businesses. Further, many high growth companies with proprietary technology rely on a combination of patent, copyright, trademark and trade secret protection and non-disclosure agreements to establish and protect their proprietary rights, which may be essential to the growth and profitability of the company. There can be no assurance that a particular company will be able to protect these rights or will have the financial resources to do so, or that competitors will not develop or patent technologies that are substantially equivalent or superior to the technology of a company in which ACK invests client assets. Conversely, other companies may make infringement claims against such companies, which could have a material adverse effect on these companies. The markets in which many high growth companies operate are extremely competitive. New technologies and improved products and services are continually being developed, rendering older technologies, products and services obsolete. Competition can result in significant downward pressure on pricing. There can be no assurance that these companies will successfully penetrate their markets or establish or maintain competitive advantages. Non-Diversification/Concentration. ACK may invest client accounts primarily in the equity securities of a small number of issuers and will likely be invested primarily in United States issuers. In addition, in certain cases, client accounts may be concentrated in a small number of issuers. Accordingly, a client’s portfolio may be subject to more rapid change in value than would be the case if ACK elected not to concentrate on certain issuers or maintained a wider diversification among industries, geographic areas, types of securities and issuers. Leverage. While the use of certain forms of leverage including margin borrowing, structured products or derivative instruments can substantially improve the return on invested capital, such use may also increase the adverse impact to which a client portfolio may be subject to. Borrowings will usually be from securities brokers and dealers and will typically be secured by a client’s securities and other assets. Under certain circumstances, such a broker-dealer may demand an increase in the collateral that secures portfolio obligations and if the portfolio were unable to provide additional collateral, the broker-dealer could liquidate assets held in the account to satisfy the portfolio’s obligations to the broker-dealer. Liquidation in that manner could have extremely adverse consequences. In addition, the amount of the borrowings and the interest rates on those borrowings, which will fluctuate, will have a significant effect on the portfolio’s profitability. Options. ACK may trade in put and call options, which are highly specialized activities and entail greater than ordinary investment risks. Trading put and call options can result in large amounts of leverage because option premiums paid or received by an investor are small in relation to the market value of the investments underlying the options. As a result, the leverage offered by trading in options could cause an investor’s asset value to be subject to more frequent and wider fluctuations than would be the case if the investor did not invest in options. PIPES-Contractual Risk and Regulatory Framework. As mentioned above, ACK may invest in PIPES. Unlike the purchase of freely tradable common stock in the open market, the PIPES investments generally involve contractual obligations by the issuer of such securities requiring the issuer to take certain actions, such as registering the securities or, in the case of convertible securities, issuing the underlying securities upon exercise of convertible securities and registering the underlying securities with the appropriate federal and state authorities for resale. There can be no assurances that any issuer will succeed in registering for public resale the securities held by client portfolios or that registration of securities pursuant to any such arrangement will create liquidity. SPACs (special purpose acquisition companies). SPACs are companies without any revenue or operating history that raise capital in initial public offerings (IPOs) for the purpose of acquiring an operating company. SPACs are offered at a set price as units with two components: shares of common stock and a

Item 7: Types of clients

ACK’s clients are the Private Funds. Investors in the Private Funds are not considered advisory clients of ACK and cannot participate in investment decisions. The minimum investment amount in the Private Funds is $500,000. The minimum investment amount may be waived by the General Partner or Adviser and has been so waived for certain investors.

Item 6: Performance-based fees and side-by-side management Conflicts of interest

The Adviser has entered into performance fee arrangements with the Private Funds. The Adviser structures any performance or incentive fee arrangement subject to Section 205(a)(1) of the Investment Advisers Act of 1940 in accordance with the available exemptions thereunder, including the exemption set forth in Rule 205-3. In measuring clients' assets for the calculation of performance-based fees, the Adviser includes realized and unrealized capital gains and losses. Performance-based fee arrangements may create an incentive for the Adviser to recommend investments that may be riskier or more speculative than those which would be recommended under a different fee arrangement. Such fee arrangements also create an incentive to favor higher fee-paying accounts over other accounts in the allocation of investment opportunities. The Adviser has procedures designed to ensure that all clients are treated fairly and equally and to mitigate this conflict from influencing the allocation of investment opportunities among clients. Investment opportunities are typically allocated pari passu.

Item 10: Other financial industry activities and affiliations Conflicts of interest

Neither ACK nor any of its management persons are registered, or have an application pending to register, as a broker-dealer, futures commission merchant, commodity pool operator, a commodity trading advisor, or as a registered representative or associated person of such entities. ACK GP, which is a Delaware limited liability company, is the General Partner of three of the Private Funds managed by ACK. Richard S. Meisenberg and John H. Reilly III are the managing members of ACK GP. Currently, ACK does not have any client accounts other than the Private Funds which, as explained in Item 4, consist of four Private Funds sponsored by ACK. All Private Funds are typically managed on a pari passu basis.

Item 11: Code of ethics, participation or interest in client transactions and personal trading Conflicts of interest

ACK strives to adhere to the highest industry standards of integrity, professionalism and trust. To this end, ACK has adopted a Code of Ethics (the “Code”) that generally requires ACK employees to comply with all applicable federal securities laws, place the interests of clients first, avoid conflicts of interest, not take inappropriate advantage of the employee’s position, adhere to certain restrictions with respect to the receipt and giving of gifts and safeguard confidential information. Each employee is required to report to ACK’s Chief Compliance Officer any known or suspected violations of the Code or law. ACK has implemented procedures relating to personal securities transactions and insider trading that are designed to mitigate the associated conflicts of interest. These procedures include specific trade reporting and pre-clearance requirements. According to the Code, ACK employees arrange to have duplicates of certain brokerage statements, a quarterly holdings report provided to ACK or have setup automatic, electronic capture of their personal trading. ACK’s Chief Compliance Officer or his designee reviews a sample of personal transaction and holdings to ensure that such transactions have been conducted in a manner consistent with the Code. Except with respect to certain exempted transactions, no ACK employee may purchase or sell any security without first obtaining pre-clearance pursuant to the approval process set forth in the Code. One of the fundamental principles of the Code is that managing members, officers and employees of ACK have a fiduciary duty to place Client interests ahead of ACK’s interest or their own and to conduct all personal securities transactions in a manner that does not interfere with Client transactions or otherwise take unfair advantage of the relationship of the managing member, officer or employee to Clients. ACK provides all personnel with a copy of the current Code and such personnel are required to provide ACK with a written acknowledgement of their receipt of the Code and understanding of its requirements on an annual basis. Training is provided for employees with respect to the Code and their duties under it. An existing or prospective client or Private Fund investor may obtain a copy of the Code by contacting Andres Aguirre, Chief Compliance Officer, at (914) 358-3299 and/or via electronic mail to aaguirre@ackasset.com. Insider Trading Policy. ACK has adopted an "Insider Trading” policy in accordance with Advisers Act Section 204A, which prohibits the misuse of material nonpublic information by ACK and all of its personnel. In addition, the Code contains restrictions on using inside information to engage in any personal transactions to disclose any material nonpublic information. In accordance with these policies, to prevent trading of public securities based on material, non-public information, ACK maintains and regularly updates a “restricted” securities list of companies about which ACK employees may have material, non-public information. Any ACK managing member, officer, employee or other access person who fails to observe the abovedescribed policies risks serious sanctions, including dismissal and personal liability.

Gift & Entertainment Policy. Our employees may occasionally give or receive gifts, meals or entertainment, subject to compliance with applicable laws, regulations and ACK’s policies and procedures. ACK’s policy addresses conflicts of interest related to gifts and entertainment, including the appearance of having given or received something of value that could influence ACK’s business decisions or the business decisions of clients. The policy requires the reporting and preclearance, when possible, of gifts, meals and entertainment given or received which exceed certain thresholds. In addition, our employees are prohibited from soliciting the receipt of gifts, meals or entertainment. Senior management periodically reviews summaries of gifts and entertainment activity to detect trends of abuse, conflicts of interest, or possible violations of the policy.

Item 12: Brokerage practices Conflicts of interest

Best Execution. In determining the ability of a broker or dealer to provide best execution of securities transactions, ACK considers a number of factors, including the execution capabilities required by the transactions; the importance of speed, efficiency and confidentiality; the broker or dealer's apparent familiarity with sources from or to whom particular securities might be purchased or sold; the reputation and perceived soundness of the broker or dealer; as well as other matters relevant to the selection of a broker or dealer for portfolio transactions. ACK does not accept client directed brokerage. Commission Rates or Equivalents. ACK will endeavor to be aware of the current level of the charges of eligible brokers and to minimize the expenses incurred for effecting portfolio transactions to the extent consistent with clients' interests and objectives. Although ACK generally seeks competitive commission rates, it will not necessarily pay the lowest commission or commission equivalent. Transactions may involve specialized services on the part of the broker or dealer involved and thereby entail higher commissions or their equivalents than would be the case with other transactions requiring more routine services. Commission rates are generally higher for small and mid-cap equities. Use of Soft Dollar Arrangements. When appropriate under its discretionary authority and consistent with its duty to obtain best execution, ACK may direct brokerage transactions for client accounts to brokerdealers who provide ACK with research and brokerage services. The brokerage commissions used to acquire these services are known as "soft dollars." ACK uses its prime broker to execute soft dollar trades or may have the prime broker step out trades to other soft dollar brokers used by ACK. ACK only utilizes soft dollars to the extent they comply with Section 28(e) of the Securities Exchange Act of 1934, which provides a "safe harbor" that allows ACK to pay for research and brokerage services with soft dollars. In determining whether a service or product qualifies as research or brokerage, ACK must evaluate whether the service or product provides lawful and appropriate assistance to it in carrying out its investment decision-making responsibilities. Brokerage and research services that may be provided under Section 28(e) include: (1) furnishing advice as to the capital of securities, the advisability of investing in, purchasing or selling securities, and the availability of securities or purchasers or sellers of securities; (2) furnishing analyses and reports and sponsoring seminars or conferences concerning industries, issuers, securities, economic factors and trends, portfolio strategy, and the performance of accounts; and (3) effecting securities transactions and performing functions incidental thereto (such as clearance, settlement, and custody). Section 28(e) permits ACK, under certain circumstances, to cause clients to pay brokers and dealers a commission for effecting portfolio transactions in excess of the commission another broker or dealer would have charged to effect such transactions. Broker-dealers typically provide a bundle of services, including research and execution. The services provided can be either proprietary (created and provided by the broker-dealer, including tangible research products as well as access to analysts and traders) or third-party research (created by a third party but provided by the broker-dealer). ACK may use soft dollars to acquire either type. It may not be possible to place a value on the special executions or on the research services ACK receives from broker dealers effecting security transactions. Accordingly, ACK may pay brokerdealers commissions for effecting clients' portfolio transactions in excess of amounts other broker-dealers would have charged for effecting similar transactions if ACK determines in good faith that such amounts

are reasonable in relation to the benefit of the brokerage and/or research services provided by those brokerdealers, viewed either in terms of a particular transaction or ACK’s overall duty to its discretionary clients. Examples of services which ACK has paid for with client commissions during the last fiscal year include certain market publications and commentaries, research and data reports, economic forecasts, Bloomberg and similar 28(e) permitted services. The receipt of research in exchange for soft dollars benefits ACK by allowing ACK, at no cost, to supplement its own research and analysis activities. This creates a conflict of interest which ACK recognizes, in which ACK may select brokers based on the research they provide ACK through the use of soft dollars, rather than best execution services they may provide or lower execution costs to the client. ACK mitigates this conflict by periodically reviewing the execution quality and commission rates charged by its various brokerdealers. Research or brokerage services obtained in this manner are used in servicing all of ACK’s clients’ accounts. Block Trading and Trade Allocation. ACK portfolio managers will aggregate orders where appropriate for the participating clients and consistent with ACK’s duty to seek best execution. This practice may enable ACK to seek more favorable executions and net prices for the combined order. However, ACK is not obligated to aggregate orders if portfolio management decisions for different Private Funds are made separately or if ACK determines that aggregating trades would be inconsistent with ACK’s investment management duties or with any investment objectives, guidelines or restrictions applicable to a particular Private Fund. All orders placed for execution on an aggregated basis are subject to ACK's allocation policies and procedures. Trades are typically allocated among Private Funds on a pari passu basis. Cross Trades. To the extent permitted by applicable law and client governing documents, ACK can effect “cross transactions” between client accounts. ACK will only recommend such transactions if it reasonably believes that such transactions are consistent with the best interests of each Client involved and at prices that ACK believes constitutes a fair valuation. Trade Errors. ACK’s goal is to execute trades seamlessly on behalf of Clients. However, trade errors can occur for a variety of reasons. It is ACK’s policy to ensure that any trade error is identified and corrected in an expeditious manner, and that reasonable steps are taken to mitigate trading losses. Wherever possible, erroneous trades will be cancelled with the broker-dealer. If an incorrect trade entry cannot be cancelled, ACK will promptly enter into a corrective transaction and investigate the matter to determine a resolution. The goal of error correction is to return Clients to the position as if the error had not occurred (to make the client “whole”) in terms of the originally intended trade, the erroneous trade, and transaction costs. However, ACK is responsible only for its own errors and not for the errors of others. If a trade error is caused by a third party, such as a broker-dealer, ACK will take reasonable steps to recover from the third party the losses resulting from that error. Additional Services. The General Partner may select one or more firms to serve as prime broker (“Prime Broker”) to hold the funds and securities of, and execute transactions for, each Private Fund, consistent with ACK’s effort to seek best execution. In addition to custody and execution, a Prime Broker may provide other core functions (such as reporting, clearing, financing, securities lending, and client service) as well as value-added services (such as capital introductions, advanced research and analytics and technology services) to the Private Fund. ACK may choose which broker effects a particular transaction and, on occasion, the amount of commission the Private Fund pays for such trade. ACK may on occasion “trade away” for specific trades, executing trades through brokers other than the Prime Broker in an effort to gain access to greater inventory or better price or execution.

Item 14: Client referrals and other compensation Conflicts of interest

Currently, ACK does not employ any promoters. However, ACK has in the past and may again in the future enter into agreements to compensate third parties for client referrals. Any such referral arrangements will comply with the relevant “testimonials and endorsements” portions of the "advertising rule" (Advisers Act Rule 206(4)-1). In particular, compensated third party referral arrangements will be subject to a written agreement between ACK and the third party and all required disclosures will be made. Prime Brokers or other brokerage firms may also solicit Investors for the Private Funds as described above. Such solicitations will comply with applicable law.

Item 9: Disciplinary information

Registered investment advisers are required to disclose all material facts regarding any legal or disciplinary events that would be material to the evaluation of the Adviser or the integrity of its management. ACK has no applicable disciplinary information.

Item 13: Review of accounts

As described in Item 4, ACK is the investment adviser to four Private Funds sponsored by ACK. ACK’s portfolio managers review accounts on an ongoing basis. In addition, ACK’s Chief Compliance Officer periodically reviews the Private Funds to ensure adherence to stated investment objectives, investment restrictions and limitations, as well as to Adviser's trading and trade allocation policies and procedures. ACK provides quarterly letters to each investor in the Private Funds. In addition, investors receive monthly statements of changes in net asset value and performance. ACK may also create customized reports at a Clients' request. In certain instances, the Chief Compliance Officer may prepare periodic reports confirming compliance with stated account limitations and restrictions.

Item 15: Custody

ACK GP, as General Partner to the Private Funds, is deemed to have custody of those Private Fund assets through its ability to access and control these assets and withdraw them from custodial accounts. ACK satisfies its regulatory obligation by ensuring that each Private Fund is subject to an audit at least annually by an independent public accountant that is registered with, and subject to regular inspection by, the Public Company Accounting Oversight Board, and requires that each Private Fund distribute its audited financial statements to all investors within 120 days of the end of its fiscal year.

Item 16: Investment discretion

ACK has investment discretion authority over the Private Funds subject to each Private Funds’ investment objectives, investment strategy and investment restrictions, if any. Such authority is granted to ACK contractually pursuant to the Private Funds' respective official subscription documents.

Item 17: Voting client securities

ACK has adopted Proxy Voting Policies and Procedures, which it believes are reasonably designed to ensure that proxies are voted in the best interest of Private Funds and in accordance with its fiduciary duties and Rule 206(4)-6 under the Advisers Act. ACK’s policies and procedures contain procedures designed to address potential conflicts of interest that may arise between ACK and the Private Funds which may include, but not limited to, information barriers and/or engaging a third party to independently advise how a particular proxy should be voted. ACK has sole and exclusive authority and responsibility to vote all proxies on behalf of the Private Funds. As such, neither the Private Funds nor their investors may direct how ACK should vote on a particular proxy.

Please contact Andres Aguirre, Chief Compliance Officer, at (914) 358-3299 and/or via electronic mail to aaguirre@ackasset.com if you would like a record of how proxies for your shares were voted or a copy of the Adviser’s proxy voting policies and procedures.

Item 18: Financial information

A registered investment adviser is required to provide certain financial information or disclosures about its financial condition. ACK has no financial commitment that impairs its ability to meet contractual and fiduciary commitments to clients and has not been the subject of a bankruptcy proceeding.

Stakes it holds

ACK Asset Management LLC has told the SEC it owns more than 5% of 4 companies, latest first (Schedules 13D and 13G).
