Use of Estimates  The preparation of financial statements in conformity with U.S. GAAP requires management to make assumptions and estimates 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.  C. Adoption of New Accounting Standards  In May 2014, 2014 09, Revenue from Contracts with Customers (Topic 606 2014 09 not 2014 09.

First, the Company sometimes grant to employees and directors restricted common stock in Cohen & Company Inc. These grants vest over a period of time and only have service based vesting criteria. In these cases, the Company determines the fair value of the grants by taking the closing stock price of Cohen & Company, Inc. on the grant date and multiplying it by the number of restricted shares granted. The recipient is entitled to dividends during the vesting period but they are paid only if (and to the extent) the restricted share grant ultimately vests. The Company recognizes the expense over the service period on a straight line basis. The Company assumes no Second, the Company sometimes grants to employees operating units of the Operating LLC. These grants also vest over a period of time and only have service based vesting criteria. Because there is a fixed exchange ratio between units of the Operating LLC and shares of Cohen & Company Inc., the fair value of the grant is calculated by taking the closing stock price of Cohen & Company, Inc. on the grant date, adjusting for the exchange ratio, and then multiplying by the number of units of the Operating LLC granted. The recipient is entitled to distributions during the vesting period but they are paid only if (and to the extent) the unit grant ultimately vests. The Company recognizes the expense over the service period on a straight line basis. The Company assumes no Third, employees sometimes invest in the membership interests of consolidated SPAC sponsor entities. Because these entities are consolidated and the employees are investing in the consolidated company's non-controlling interest, these equity interests fall under ASC 718. not no S. Accounting for Income Taxes  Cohen & Company Inc. is treated as a C corporation for United States federal and state income tax purposes.  The Company's voting-controlled subsidiary, the Operating LLC, is treated as a pass-through entity for U.S. federal income tax purposes and in most of the states in which it does business. However, in the periods presented, the Operating LLC or its subsidiaries have been subject to entity level income taxes in the United Kingdom, Spain, France, New York City, and Philadelphia.  The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the U.S. GAAP and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.  The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not 23  The Company's policy is to record penalties and interest as a component of income tax expense (benefit) in the consolidated statements of operations.

The Company invests in the sponsor entities of SPACs. The sponsor entities are limited liability companies (each an "LLC") that pool their members' interests and invest in the private placement of a SPAC. The SPAC will also raise funds in a public offering and seek to complete a business combination within an agreed upon time frame. The SPAC will use the proceeds raised from the private placement to pay transaction and operating expenses during the period it is seeking a business combination. The proceeds of the public offering are placed in an interest bearing trust and can only be used to complete the business combination. Generally, the public investors must approve any business combination prior to its effectiveness. If a business combination is not may • The sponsor entities are LLCs that give all important decision making rights to their respective managing member. Furthermore, the other members of the LLC cannot replace the managing member. Accordingly, the Company has concluded that the sponsor entities are VIEs and the managing member has the power to direct its most important economic activities. In all cases where the Company is the managing member of a sponsor entity, it has also had a significant economic interest in such sponsor entity and therefore consolidates such sponsor entity. • In all cases where the Company has consolidated a sponsor entity, it has determined that the sponsor entity's private placement investment in the SPAC which it sponsors should be treated as an equity method investment during the SPAC's pre-business combination period. Furthermore, because of the difficulty of determining the fair value of such an investment in the SPAC's pre-business combination period, the Company has chosen to not • If a SPAC completes its business combination, the sponsor entity's investment in the SPAC will be converted to a combination of unrestricted and restricted shares in the post-business combination SPAC. At this point (assuming the Company consolidates the sponsor entity), the Company will account for the shares received at fair value. It will reclassify any remaining equity method investment to other investments, at fair value and record principal transactions income for the difference. The Company will record non-controlling interest expense for the SPAC shares that are distributable to the non-controlling interest holders of the sponsor entity. The fair value of the unrestricted shares received is equal to the public trading price of the SPAC on the date of the business combination. The fair value of the restricted shares received is adjusted downwards from the public trading price for certain sale restrictions imposed (generally, they are restricted for sale for some time period and subject to certain hurdle prices before they become freely tradeable). The Company uses a Monte Carlo simulation model to determine the appropriate discount to place on shares that are subject to hurdle prices. In the case of a SPAC business combination where the Company consolidates the sponsor entity, generally there is also an equity-based compensation entry to be recorded at the date of the business combination. See equity-based compensation section above. The Company will continue to mark the sponsor entity's investment in the SPAC to market and record principal transactions income or loss and offsetting non-controlling interest income or expense until the sponsor entity itself distributes all of the SPAC shares it owns to its members and liquidates. At that point, the Company will hold the SPAC shares directly (rather than through a consolidated subsidiary) and will record principal transaction income and loss until the SPAC shares themselves are liquidated. • The Company will also invest in sponsor entities that it does not not not not • If a SPAC completes a business combination and the Company has an equity method investment in the associated sponsor entity, the sponsor entity will record income equal to the difference between the fair value of the restricted and unrestricted shares it receives and the carrying value of its equity method investment in the SPAC. The Company will recognize its share of this gain as income from equity method affiliates. The sponsor entity will continue to mark its investment in the SPAC to market after the business combination and the Company will recognize its share of the change in fair value as income or loss from equity method affiliates. Once the sponsor entity distributes the Company's share of the SPAC shares it owns, the Company will reclassify its investment from investment in equity method affiliate to other investments, at fair value as the Company will hold the SPAC shares directly (rather than through an equity method investee). The Company will then record principal transactions income and loss until the SPAC shares themselves are liquidated. • If a SPAC liquidates and the Company has an investment in it (either directly in the case of consolidated sponsor entities or indirectly in the case of equity method sponsor entities), the Company will write off its remaining equity method balance and record loss on equity method investment. In the case of consolidated sponsor entities, the Company will also record an offsetting entry to non-controlling interest.  Y.

The Company then recorded non-controlling interest expense or compensation expense related to the Sponsor Shares distributable to the non-controlling interest holders in the Insurance SPAC Sponsor Entities. If the non-controlling interest holder was an employee, the Company recorded the expense as equity-based compensation expense. Otherwise, the expense was recorded as non-controlling interest expense. Subsequent to the closing of the Insurance SPAC Merger, any change in the fair value of the shares held by the Insurance SPAC Sponsor Entities has been recorded as a component of principal transactions and other income.

First, the Company sometimes grant to employees and directors restricted common stock in Cohen & Company Inc. These grants vest over a period of time and only have service based vesting criteria. In these cases, the Company determines the fair value of the grants by taking the closing stock price of Cohen & Company, Inc. on the grant date and multiplying it by the number of restricted shares granted.

Income Tax, Policy [Policy Text Block]	S. Accounting for Income Taxes  Cohen & Company Inc. is treated as a C corporation for United States federal and state income tax purposes.  The Company's voting-controlled subsidiary, the Operating LLC, is treated as a pass-through entity for U.S. federal income tax purposes and in most of the states in which it does business. However, in the periods presented, the Operating LLC or its subsidiaries have been subject to entity level income taxes in the United Kingdom, Spain, France, New York City, and Philadelphia.  The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the U.S. GAAP and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

Investments in Special Purpose Acquisition Companies ("SPACs") Sponsor Entitles [Policy Text Block]	X. The Company invests in the sponsor entities of SPACs. The sponsor entities are limited liability companies (each an "LLC") that pool their members' interests and invest in the private placement of a SPAC. The SPAC will also raise funds in a public offering and seek to complete a business combination within an agreed upon time frame. The SPAC will use the proceeds raised from the private placement to pay transaction and operating expenses during the period it is seeking a business combination. The proceeds of the public offering are placed in an interest bearing trust and can only be used to complete the business combination. Generally, the public investors must approve any business combination prior to its effectiveness. If a business combination is not may • The sponsor entities are LLCs that give all important decision making rights to their respective managing member. Furthermore, the other members of the LLC cannot replace the managing member. Accordingly, the Company has concluded that the sponsor entities are VIEs and the managing member has the power to direct its most important economic activities. In all cases where the Company is the managing member of a sponsor entity, it has also had a significant economic interest in such sponsor entity and therefore consolidates such sponsor entity. • In all cases where the Company has consolidated a sponsor entity, it has determined that the sponsor entity's private placement investment in the SPAC which it sponsors should be treated as an equity method investment during the SPAC's pre-business combination period. Furthermore, because of the difficulty of determining the fair value of such an investment in the SPAC's pre-business combination period, the Company has chosen to not • If a SPAC completes its business combination, the sponsor entity's investment in the SPAC will be converted to a combination of unrestricted and restricted shares in the post-business combination SPAC. At this point (assuming the Company consolidates the sponsor entity), the Company will account for the shares received at fair value. It will reclassify any remaining equity method investment to other investments, at fair value and record principal transactions income for the difference. The Company will record non-controlling interest expense for the SPAC shares that are distributable to the non-controlling interest holders of the sponsor entity. The fair value of the unrestricted shares received is equal to the public trading price of the SPAC on the date of the business combination. The fair value of the restricted shares received is adjusted downwards from the public trading price for certain sale restrictions imposed (generally, they are restricted for sale for some time period and subject to certain hurdle prices before they become freely tradeable). The Company uses a Monte Carlo simulation model to determine the appropriate discount to place on shares that are subject to hurdle prices. In the case of a SPAC business combination where the Company consolidates the sponsor entity, generally there is also an equity-based compensation entry to be recorded at the date of the business combination. See equity-based compensation section above. The Company will continue to mark the sponsor entity's investment in the SPAC to market and record principal transactions income or loss and offsetting non-controlling interest income or expense until the sponsor entity itself distributes all of the SPAC shares it owns to its members and liquidates. At that point, the Company will hold the SPAC shares directly (rather than through a consolidated subsidiary) and will record principal transaction income and loss until the SPAC shares themselves are liquidated. • The Company will also invest in sponsor entities that it does not not not not • If a SPAC completes a business combination and the Company has an equity method investment in the associated sponsor entity, the sponsor entity will record income equal to the difference between the fair value of the restricted and unrestricted shares it receives and the carrying value of its equity method investment in the SPAC. The Company will recognize its share of this gain as income from equity method affiliates. The sponsor entity will continue to mark its investment in the SPAC to market after the business combination and the Company will recognize its share of the change in fair value as income or loss from equity method affiliates. Once the sponsor entity distributes the Company's share of the SPAC shares it owns, the Company will reclassify its investment from investment in equity method affiliate to other investments, at fair value as the Company will hold the SPAC shares directly (rather than through an equity method investee). The Company will then record principal transactions income and loss until the SPAC shares themselves are liquidated. • If a SPAC liquidates and the Company has an investment in it (either directly in the case of consolidated sponsor entities or indirectly in the case of equity method sponsor entities), the Company will write off its remaining equity method balance and record loss on equity method investment. In the case of consolidated sponsor entities, the Company will also record an offsetting entry to non-controlling interest.

[1]	Represents the interest rate in effect as of the last day of the reporting period.
[2]	The holder of the 2017 Convertible Note may convert all or any part of the outstanding principal amount at any time prior to maturity into units of membership interests of the Operating LLC at a conversion price of $1.45 per unit, subject to customary anti-dilution adjustments. Units of membership interests of the Operating LLC not held by Cohen & Company Inc. may, with certain restrictions, be redeemed and exchanged into shares of the Cohen & Company Inc. common stock, par value $0.01 per share ("Common Stock") on a tenfor- one basis. Therefore, the 2017 Convertible Note can be converted into Operating LLC units of membership interests and then redeemed and exchanged into Common Stock at an effective conversion price of $14.50. See note 21.
[3]	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 December 31, 2020 on a combined basis was 11.58% assuming the variable rate in effect on the last day of the reporting period remains in effect until maturity.

[1]	The Operating LLC units of membership interests 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 Operating LLC units of membership interests 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 units are not included in the computation of basic earnings per share. These 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.
[2]	An adjustment is included because the Company would have incurred a higher income tax expense or realized a higher income tax benefit if the Operating LLC units of membership interests had been converted at the beginning of the period.
[3]	Potentially diluted securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows: Year Ended December 31, 2020 2019 2018 2017 Convertible Note 1,034,483 1,034,483 - 2013 Convertible Notes 414,882 352,292 274,917 Restricted Common Stock 15,101 26,380 - Restricted Operating LLC units 3,752 - - 1,468,218 1,413,155 274,917
