Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value MeasurementsUnder the FASB ASC 820, Fair Value Measurements and Disclosures, a fair value measurement is determined based on the assumptions that a market participant would use in pricing an asset or liability. A three-tiered hierarchy draws distinctions between market participant assumptions based on (i) observable inputs such as quoted prices in active markets (Level 1), (ii) inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2) and (iii) unobservable inputs that require the Company to use present value and other valuation techniques in the determination of fair value (Level 3).4.

In fiscal year 2020, the Company sold all 200,000 shares of Calavo common stock for a total of $11,048,000, recognizing a loss of $6,299,000.
