Investment in Non-Marketable Securities	Note 6 Investment in Non-Marketable Securities On January 15, 2021, the Capstone acquired a minority interest in a consumer products company, Diamond Products, LLC (“Diamond”), a sexual wellness holding company. The structure of the transaction was as follows: i) Brookstone Acquisition Partners XXI Corporation (“Brookstone XXI”) contributed its approximately 95% equity interest in Diamond, which represented approximately 62% equity ownership on a fully-diluted basis, to Diamond Products Holdings, LLC (“DPH”); ii) The Company formed Capstone Beta LLC (“Beta”) as a wholly-owned subsidiary, and Beta purchased a portion of Brookstone XXI’s interest in DPH; iii) Beta issued a promissory note to Brookstone XXI in the original principal amount of $8.0 million, bearing interest at 1% per annum over a 36 month term, and secured its obligations thereunder by pledging Beta’s interests in DPH; and iv) As additional credit support, Capstone issued a limited payment guaranty to Brookstone XXI in the amount of 10% of the principal amount of Beta’s promissory note. The terms of the promissory note issued by Beta to Brookstone XXI include provisions whereby in the event that the membership interests in Diamond are sold or otherwise disposed of, any proceeds received by Beta are to be utilized to prepay the promissory note to Brookstone XXI and Brookstone XXI’s remaining recourse for the remaining note balance, if any, is limited to the pledged collateral (Beta’s membership interest in DPH) and the $800.0 thousand limited payment guarantee provide by Capstone. DPH was structured to hold one asset, the membership interest in Diamond, and accordingly upon the sale or other disposition of the membership interests in Diamond, the sole recourse of payment by Brookstone XXI is the $800.0 thousand limited payment guarantee. In summary, the intent of Brookstone XXI and the special committee of Capstone’s independent directors entering into this arrangement was to limit Capstone’s downside risk to $800.0 thousand. The 20% minority investment in DPH represented an effective 19% equity interest in Diamond and approximately 12% on a fully-diluted basis. The Company does not have the ability to exercise significant influence over operating and financial policies of Diamond and DPH. On November 9, 2023 in connection with a restructuring and recapitalization transaction of Diamond’s operating entities, Diamond and other related party entities affiliated with Brookstone XXI entered into a transaction that sold 100% of the membership interest in Diamond inclusive of Beta’s minority interest in Diamond via its membership interest in DPH to a third party. No cash consideration was received in this transaction. Rather, the primary consideration received by the selling parties was the release of guarantees of senior debt of Diamond operating entities. The third party assumed none of the $8.0 million debt liability and no other consideration was transferred. As a result, the Company’s wrote-off its equity investment in DPH from $8.0 million to zero, and recognized a $7.2 million gain on debt extinguishment from Brookstone XXI’s debt forgiveness which was consistent with the terms of the note agreement that limited Captone’s risk upon sale or disposition of Diamond’s membership interests to the $800.0 thousand limited guaranty provided by Capstone which is the net amount of the loss recognized in the 2023 statement of operations from this transaction. The remaining unsecured debt liability $800.0 thousand plus accrued interest will remain on the Company’s balance sheet with a maturity date of June 30, 2026.
