Ann: Investor Presentation - May 2015, page-22

Looks like a couple of the Top 20 holders are selling out at these prices, hence the downward pressure on price.

The two biggest culprits hold less than 5% individually hence why we're not seeing notices for reductions in substantial holdings, but between the both of them they still hold 21.5 mill which is months worth at today's rate if they are looking for a complete exit.

Also, tough to identify who the new shares were issued to as they look to all be hidden in nominee accounts.
