The Shares to which this Schedule 13D relates were acquired for an aggregate purchase price of $21,246,660.70, inclusive of brokerage commissions. Funds for the purchase were obtained from the available working capital of the Fund, which may include borrowings under portfolio margin agreements with the Fund's custodians. Positions in the Shares to which this Schedule 13D relates may be held in margin accounts and may be pledged as collateral security for the repayment of debit balances in such accounts. Since other securities may be held in such margin accounts, it may not be possible to determine the amounts, if any, of margin used to purchase the Shares.

The Reporting Persons purchased the Shares based on the Reporting Persons' belief that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable. With respect to the preliminary proxy statement on Schedule 14A filed by the Issuer on October 16, 2025, the Reporting Persons have communicated their belief that the proposals are not approvable in their current form to the Issuer. The Reporting Persons are supportive of an orderly winding up process that promptly distributes the trust account to Class A shareholders and proportionally allocates settlement proceeds, net of expenses, between the Class A and Class F shareholders. No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer's financial position and investment strategy, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with management and the Board, engaging in discussions with shareholders of the Issuer or other third parties about the Issuer and the Reporting Persons' investment, including potential business combinations or dispositions involving the Issuer or certain of its businesses, making recommendations or proposals to the Issuer concerning changes to the capitalization, ownership structure, board structure (including board composition), potential business combinations or dispositions involving the Issuer or certain of its businesses, or suggestions for improving the Issuer's financial and/or operational performance, purchasing additional Shares, selling some or all of their Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares, including swaps and other derivative instruments, or changing their intention with respect to any and all matters referred to in Item 4.

Percentage of Class

The aggregate percentage of Shares reported owned by the Reporting Persons is based on 13,724,863 Shares outstanding as of August 14, 2025, which is the total number of Shares outstanding as reported on the cover page of the Issuer's Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on August 14, 2025. As of the close of business on October 21, 2025, the Fund beneficially owned 1,875,115 Shares, constituting approximately 13.7% of the Issuers outstanding Shares. Cable Car, as the general partner of the Fund, may be deemed the beneficial owner of the 1,875,115 Shares owned by the Fund.
