Related Parties	Note I - Related Parties In March 2015, two of the Company’s executive officers invested in a start-up customer, Petzila, Inc. (“Petzila”). The executive officers’ investments constituted less than 2% (individually and in aggregate) of the outstanding beneficial ownership of Petzila, according to information provided by Petzila to the executive officers. On April 30, 2018, the Company foreclosed on its security interest and held a public sale of the assets in accordance with the requirements of Article 9 of the California Uniform Commercial Code. The Company acquired all of the assets of Petzila as the winning bidder at the public sale by a credit bid of $3,500,000, the aggregate amount of Petzila’s liability to the company. Concurrent with the foreclosure sale, the Company entered into an Asset Purchase Agreement with Wagz whereby the Company sold the assets to Wagz for $350,000 cash, 600,000 shares of Wagz common stock and an earn-out based on sales by Wagz generated from use of the assets through July 31, 2022. The earn-out is $6.00 per unit of a product specified in the asset purchase agreement and any upgrade to such product. The fair value of the non-cash consideration consisted of $600,000 for the 600,000 shares of Wagz common stock which is recorded within other assets. The Company determined the fair value of the equity using the price per common share received by Wagz in the most recent financing transaction, a level 3 input.
