Ann: Investor Presentation October 2012 , page-43

top 20 updated to 29/10/12, so effectively updating for the 1.24m that were traded 24/10/12. Camac only sold ~300k that day so say HSBC had the rest (900k) that leaves HSBC with 800k as at 29/10 (they had 1.69m 26/10)

Camac 5.4m at 29/10 (confirmed on T20), HSBC 0.8m (my estimate),envelope calcs have 3.46m traded since then but yet to settle -

Thu 25th 275,000
Fri 26th 643,278
Mon 29th 1,753,158
Tue 30th 795,875 (not included the off market 30k)
Total 3.46m

Total overhang as low as 2.75m (5.4+0.8-3.46) if it is only HSBC and Camac selling. I'm hoping that gets cleaned up in the next few days.

btw - Thanks for the video link Dist!!
