Context This Form 4 reports share sales (dispositions) rather than purchases or option exercises. Sales by insiders can be for many personal or tax-related reasons and are not, by themselves, a definitive signal about the company’s outlook. The filing shows at least part of the sale came from an entity Mr. Slusky controls (Abalone Cove LLLP).
