The Form 4 was filed by Eric Polis when restricted shares owned by ASI Technology Corporation and its subsidiary were sold in a private transaction. This is stated on the form. Eric Polis had beneficial ownership over those shares and, as a member of the EDIG BOD, had to file a timely Form 4 when they were sold.
Jerry Polis, who also had beneficial ownership of those shares, has no requirement to file Form 4's after such transactions. As a greater than 5% owner, he only has to file an annual update of his holdings. However, as I posted on RB several months ago, Jerry Polis had sold a few million shares last year and the year before.
