Do not follow. The shares that were put up as collateral is Biocell shares. From the 10k (12/31/2014)--
"On September 29, 2014, the Company closed a transaction whereby it sold its ownership stake in BioCells, amounting to 50.004% of the outstanding shares of BioCells to Diego Rissola, who is the current President and Chairman of the Board of BioCells and a shareholder prior to the transaction.Pursuant to the Agreement, the Shares are pledged by the Purchaser in favor of the Company to secure the Purchaser’s performance under the Agreement, as are an additional 4,503 Class B shares held by the Purchaser". I wouldn't use Yahoo as a source, only the SEC filings. Am I wrong?
