Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	(7) Fair Value Measurements – Fair value, as defined by US GAAP, 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 in the principal or most advantageous market. US GAAP establishes a hierarchy in determining the fair value of an asset or liability. The fair value hierarchy has three levels of inputs, both observable and unobservable. US GAAP requires the utilization of the lowest possible level of input to determine fair value. Level 1 inputs include quoted market prices in an active market for identical assets or liabilities. Level 2 inputs are market data, other than Level 1 inputs, that are observable either directly or indirectly. Level 2 inputs include quoted market prices for similar assets or liabilities, quoted market prices in an inactive market, and other observable information that can be corroborated by market data. Level 3 inputs are unobservable and corroborated by little or no market data. At March 31, 2021 and December 31, 2020, the Company had no financial assets or liabilities measured at fair value on a recurring basis or nonrecurring basis that would require disclosure. The Company had the following nonfinancial assets measured on a nonrecurring basis that were recorded at fair value during 2020. At December 31, 2020, the Advance Auto store in Middletown, Ohio was written down to its estimated fair value of $82,500 after completing our long-lived asset valuation analysis. The resulting impairment charge of $78,376 was included in earnings for the fourth quarter of 2020. The fair value of the property was based upon comparable sales of similar properties, which are considered Level 2 inputs in the valuation hierarchy.
