On an ongoing basis, management evaluates its estimates and judgments, including, among other items, those related to fair value of investments, revenue recognition, accrued expenses, financing operations, fair value of goodwill, fixed asset lives and impairment, lease right-of-use assets and impairment, deferred tax assets, liabilities and valuation allowance, other assets, the present value of lease liabilities, and contingencies and litigation.

The estimate of the allowance for doubtful accounts, which is the recorded allowance for doubtful accounts and bad debt expense, is based on management’s assessment of current economic conditions and historical collection experience with each customer. Specific customer receivables are considered past due when they are outstanding beyond their contractual terms and are written off from the allowance for doubtful accounts when an account or invoice is individually determined to be uncollectible.

Income (Loss) Per Share Basic income (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of shares of common stock outstanding during the period. In periods of net loss, diluted loss per share is calculated similarly to basic loss per share because the impact of all potentially dilutive common shares is anti-dilutive. In periods of net income, diluted earnings per share is computed using the more dilutive of the “two-class method” or the “treasury method.” Dilutive earnings per share under the “two-class method” is calculated by dividing net income available to common stockholders as adjusted for the participating securities, by the weighted-average number of shares outstanding plus the dilutive impact of all other potentially dilutive common shares, consisting primarily of common shares underlying common stock equity incentives. Dilutive earnings per share under the “treasury method” is calculated by dividing net income available to common stockholders by the weighted-average number of shares outstanding plus the dilutive impact of all potentially dilutive common shares, consisting primarily of common shares underlying common stock equity incentives.

Fair Value Disclosures [Text Block]	NOTE 5. GAAP defines fair value as the amount that would be received from the sale of an asset or paid for the transfer of a liability in an orderly transaction between market participants at the measurement date, and establishes a hierarchy for disclosing assets and liabilities measured at fair value based on the inputs used to value them. The fair value hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs. Observable inputs are based on market pricing data obtained from sources independent of the Company. Unobservable inputs reflect management’s judgment about the assumptions market participants would use in pricing the asset or liability. The fair value hierarchy includes three ● Level I - inputs are quoted prices in active markets as of the measurement date for identical assets and liabilities that the Company has the ability to access. This category includes exchange-traded mutual funds and equity securities; ● Level II - inputs are inputs other than quoted prices included in Level I that are observable for the asset or liability, either directly or indirectly. Level II inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates or yield curves, that are observable at commonly quoted intervals; this category includes mortgage-backed securities, asset-backed securities, corporate debt securities, certificates of deposit, commercial paper, U.S. agency and municipal debt securities, U.S. Treasury securities, and derivative contracts; and ● Level III - inputs are unobservable inputs for the asset or liability and include situations where there is little, if any, market activity for the asset or liability. The measurements are highly subjective. The availability of observable inputs can vary and is affected by a variety of factors. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is the greatest for assets or liabilities categorized in Level III. In certain cases, the inputs used to measure fair value may The following table presents information about the Company’s assets measured at fair value as of the years ended December 31, 2022 December 31, 2021.

Earnings Per Share, Policy [Policy Text Block]	Income (Loss) Per Share Basic income (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of shares of common stock outstanding during the period. In periods of net loss, diluted loss per share is calculated similarly to basic loss per share because the impact of all potentially dilutive common shares is anti-dilutive. In periods of net income, diluted earnings per share is computed using the more dilutive of the “two-class method” or the “treasury method.” Dilutive earnings per share under the “two-class method” is calculated by dividing net income available to common stockholders as adjusted for the participating securities, by the weighted-average number of shares outstanding plus the dilutive impact of all other potentially dilutive common shares, consisting primarily of common shares underlying common stock equity incentives. Dilutive earnings per share under the “treasury method” is calculated by dividing net income available to common stockholders by the weighted-average number of shares outstanding plus the dilutive impact of all potentially dilutive common shares, consisting primarily of common shares underlying common stock equity incentives.
