Michael Lazaridis sold enough shares to have a 4.99% ownership stake in Blackberry. Below 5% he is no longer required to file with the SEC if he wishes to dispose of any more equity.
The material part of his SEC filing is:
(c) On December 23, 2013, 1258701 sold 3,166,893 Shares at an average price per share of $7.55 and on December 24, 2013, 1258701 sold 333,107 Shares at an average price per share of $7.63, in each case through open market sales.
What a vote of confidence. He raised $26.45 million out of these transactions, which would have been a quarter billion had he done this three years ago!
