Thanks for taking the trouble to ID the source. I actually found it as well and was about to post an apology.
The only number I was right is the 11% owned by Keith Barron (3,830,000 x 4 = 15,320,000 divided by about 134 million shares o/s = 11.4%). Anyway, management and the inistitutions control about 75% of ARU and only 25% are held by the retail investors.
Again, I would check and verify my source in the future.
