I compared the old policy with the new and could see only two differences. In the case of the old policy an ownership takeover was an exceptional circumstance not requiring notification, now in the new it does. The second difference was that the new policy recommends or guides directors to make trades in a tighter time frame, specifically in the, I think it was four days or so, after announcements.

Overall my impression was that there wasn't a great deal to worry about it in the policy change it just seemed to be routine. Being seen to be doing the right thing sort of stuff. Recently there had been a minor slip up in reporting a transaction in a very small number of shares by one of the directors.
