Fair Value Disclosures [Text Block]	NOTE 10 – FAIR VALUE ACCOUNTING Financial instruments measured at fair value are classified into one of three levels in the fair value hierarchy according to the significance of the inputs used in making the measurement. The three levels of the fair value hierarchy are as follows: Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 — Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3 — Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity). The Company’s marketable equity securities are valued using quoted market prices in active markets and as such are classified within Level 1 of the fair value hierarchy. The fair value of the marketable equity securities was $1,402 as of November 30, 2020 ($935 as of November 30, 2019), calculated as the quoted market price of the marketable equity security multiplied by the quantity of shares held by the Company.
