A NORMAL COURSE BUYBACK WOULD HAVE TAKEN YEARS TO EXECUTE.
Limits on daily and monthly volume would have taken a long, long time. It makes sense on a regular basis now that the big chunk of shares is out of circulation to buy and eliminate smaller lots daily and monthly.
It will add over $40 million per year in dividends in less than 18 months and going forward and add over $400 million in market cap value per share because of PE multiples.
If you don't get it, you are slow.
