Fair Value Disclosures [Text Block] | NOTE 5. Authoritative accounting guidance defines fair value, establishes a framework for measuring fair value, and establishes a fair value hierarchy which prioritizes the inputs to valuation techniques. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market. Valuation techniques that are consistent with the market or income approach are used to measure fair value. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value are classified and disclosed in one three Level 1 Level 2 Level 3 The following tables present the carrying values and estimated fair values at December 31, 2020 September 30, 2020 December 31, 2020 Total Estimated Assets Carrying Value Level 1 Level 2 Fair Value Cash $ 27,965,000 $ 27,965,000 $ — $ 27,965,000 Cash deposits with clearing organizations 686,000 686,000 — 686,000 Receivables from broker-dealers and clearing organizations 5,198,000 — 5,198,000 5,198,000 Forgivable loans receivable 4,608,000 — 4,608,000 4,608,000 Other receivables, net 10,593,000 — 10,593,000 10,593,000 $ 49,050,000 $ 28,651,000 $ 20,399,000 $ 49,050,000 Liabilities Accrued commissions and payroll payable $ 17,993,000 $ — $ 17,993,000 $ 17,993,000 Accounts payable and accrued expenses 9,374,000 — 9,374,000 9,374,000 $ 27,367,000 $ — $ 27,367,000 $ 27,367,000 September 30, 2020 Total Estimated Assets Carrying Value Level 1 Level 2 Fair Value Cash $ 27,327,000 $ 27,327,000 $ — $ 27,327,000 Cash deposits with clearing organizations 686,000 686,000 — 686,000 Receivables from broker-dealers and clearing organizations 3,367,000 — 3,367,000 3,367,000 Forgivable loans receivable 4,269,000 — 4,269,000 4,269,000 Other receivables, net 12,394,000 — 12,394,000 12,394,000 $ 48,043,000 $ 28,013,000 $ 20,030,000 $ 48,043,000 Liabilities Accrued commissions and payroll payable $ 15,445,000 $ — $ 15,445,000 $ 15,445,000 Accounts payable and accrued expenses 9,656,000 — 9,656,000 9,656,000 $ 25,101,000 $ — $ 25,101,000 $ 25,101,000 The following tables present the financial assets and liabilities measured at fair value on a recurring basis at December 31, 2020 September 30, 2020 December 31, 2020 Total Estimated Assets Carrying Value Level 1 Level 2 Level 3 Fair Value Securities owned: Corporate stocks $ 216,000 $ 216,000 $ — $ — $ 216,000 Municipal bonds 236,000 236,000 — — 236,000 Restricted stock 696,000 — 696,000 — 696,000 Corporate bonds 323,000 323,000 — 323,000 Warrants 3,181,000 — 2,140,000 1,041,000 3,181,000 $ 4,652,000 $ 452,000 $ 3,159,000 $ 1,041,000 $ 4,652,000 Liabilities Contingent consideration $ 10,702,000 $ — $ — $ 10,702,000 $ 10,702,000 $ 10,702,000 $ — $ — $ 10,702,000 $ 10,702,000 September 30, 2020 Total Estimated Assets Carrying Value Level 1 Level 2 Level 3 Fair Value Securities owned: Corporate stocks $ 137,000 $ 137,000 $ — $ — $ 137,000 Municipal bonds 332,000 332,000 — — 332,000 Restricted stock 529,000 — 529,000 — 529,000 Corporate bonds 438,000 — 438,000 — 438,000 Warrants 3,303,000 — 2,228,000 1,075,000 3,303,000 $ 4,739,000 $ 469,000 $ 3,195,000 $ 1,075,000 $ 4,739,000 Liabilities Contingent consideration $ 10,401,000 $ — $ — $ 10,401,000 $ 10,401,000 $ 10,401,000 $ — $ — $ 10,401,000 $ 10,401,000 Changes in Level 3 three December 31, 2020 Beginning Balance as of September 30, 2020 Net realized Gain or (losses) Net Change in Unrealized Appreciation (Depreciation) Purchases Sales Transfer Into Level 3 (a) Transfer Out of Level 3 Ending Balance as of December 31, 2020 Assets Warrants $ 1,075,000 $ — $ (34,000 ) $ — $ — $ — $ — $ 1,041,000 See changes in Level 3 three December 31, 2020 7.

This model takes into account the underlying securities' current market values, the underlying securities' market volatility, the terms of the warrants, exercise prices, and the risk-free return rate. A discount is applied for the warrants' lack of marketability. The discount is based on the value of a protective put. Debt securities are valued based on recently executed transactions. |
