As I said, there are limited disclosures, just like the Chinese. In this case meaningless - I ask who owns this and you say "Blackrock" and "Northern Trust" as if you've answered the question. "Northern Trust" is not a who, it is just another layer of "secret ownership" to use the magazine's phraseology. I still have no idea who owns Exxon-Mobil - it is a secret, to use their phrase.
