In a typical SFA transaction, the Company acquires an interest in a publicly traded company (each referred to as the "SFA Counterparty") through open market purchases, direct acquisitions from the SFA Counterparty, or a combination thereof. These interests can take the form of unrestricted common shares, restricted common shares, equity derivatives, or fair value receivables. Upon acquiring these interests, the Company and the SFA Counterparty enter into an SFA derivative arrangement. In cases where the Company acquires its interests in the SFA Counterparty through open market purchases, the SFA generally requires an up-front payment from the SFA Counterparty to the Company. The amount of this payment equals the cost paid by the Company for those interests, less a shortfall amount in certain cases. To fund the shortfall portion of the initial investment, the Company will utilize available cash on hand or available financing. The SFA stipulates that the Company must make a payment to the SFA Counterparty on a certain maturity date. Depending on the terms of the SFA, this payment may Importantly, the SFA does not not Furthermore, SFAs usually include a provision allowing the Company to terminate the SFA, either in whole or in part, before its maturity by making an agreed-upon payment based on an amount defined in the agreement (the “Reset Price”).

These obligations may not not may The Company accounts for SFA transactions as follows: ● The interests in public companies that it owns are carried at fair value. Refer to note 8 ● The derivative obligation arising from the SFA is also carried at fair value. Fair value represents the amount the Company would need to pay to settle the SFA obligation at any reporting period date.

[1]The junior subordinated notes listed represent debt the Company owes to the two trusts noted above. The total par amount owed by the Company to the trusts is $49,614. However, the Company owns the common stock of the trusts in a total par amount of $1,489. The Company pays interest (and at maturity, principal) to the trusts on the entire $49,614 junior notes outstanding. However, the Company receives back from the trusts the pro rata share of interest and principal on the common stock held by the Company. These trusts are VIEs and the Company does not consolidate them even though the Company holds the common stock. The Company carries the common stock on its balance sheet at a value of $0. The junior subordinated notes are recorded at a discount to par. When factoring in the discount, the yield to maturity of the junior subordinated notes as of September 30, 2023 on a combined basis was 21.74% assuming the variable rate in effect on the last day of the reporting period remains in effect until maturity.[2]Represents the interest rate in effect as of the last day of the reporting period.

[1]An adjustment is included because the Company would have incurred a higher income tax expense or realized a higher income tax benefit, as applicable, if the LLC Units had been converted at the beginning of the period.[2]The LLC Units not held by Cohen & Company Inc. (that is, those held by the non-controlling interest) may be redeemed and exchanged into shares of the Company on a ten-for-one basis. The LLC Units not held by Cohen & Company Inc. are redeemable, at the member’s option at any time, for (i) cash in an amount equal to the average of the per share closing prices of the Common Stock for the ten consecutive trading days immediately preceding the date the Company receives the member’s redemption notice, or (ii) at the Company’s option, one tenth of a share of the Common Stock, subject, in each case, to appropriate adjustment upon the occurrence of an issuance of additional shares of the Common Stock as a dividend or other distribution on the outstanding Common Stock, or a further subdivision or combination of the outstanding shares of the Common Stock. These LLC Units are not included in the computation of basic earnings per share. These LLC Units enter into the computation of diluted net income (loss) per common share when the effect is not anti-dilutive using the if-converted method.
