Here's the information so far released:
You see, the thing about companies, banks and people doing due diligence is that you just never know who they're going to reach out to.
And we're all 6 degrees removed from the next person in any chain sequence.
So word gets around.
FYI: mutual NDA expired
"We're all 6 degrees removed from the next person in any chain sequence" probably means "At most, there are six degrees of separation between any two people. But in a small industry, there are much fewer, and word gets around faster."
The key is the first line: "doing due diligence". Ideally, the laws provide additional protection to consumers in business/consumer relations. The idea is that the relationship is asymmetrical: the business side is professional, and the consumer side is not, so the business can screw the consumer any number of ways, and the law tries to protect consumers. Of course, that's the whole point of things like binding arbitration causes: to tip the balance back in the favor of the businesses.
Businesses dealing with businesses, professional investors, banks and the like, are treated as equals, and therefore, before any collaboration, investment, loan or the like, are required to do "due diligence", where they evaluate the company's operational basis, identify any risks, unsafe practices, what their cashflow is like, etc.: the specifics depend on for what the diligence is done (obligatory wikipedia link:
https://en.wikipedia.org/wiki/Due_diligence).
To take a case: when CIG (or RSI or whatever shell company it was) applied for the Coutts loan, someone over in Coutts had to do due diligence. In a case like that, it would not be unexpected to say "Let's look at the books"; one of the major factors in determining whether to give a loan and on what terms would be how likely the company is to pay it back.
If I were to speculate, for a specialized field, they might call in an outside consultant to give their opinion. IANAL, but such a persone person would have to sign an NDA, and, while that NDA might have an expiration date, that doesn't mean that a person with access to privileged information could speak freely about that information, especially in a way that might be damaging to the business.
My best guess: he's got some "big source" that confirms what we've all known -- CIG and its 20 other manifestations are nearly out of money, and have been trying behind the scenes to keep afloat by proposing gruesome arrangements to third parties. But that's a guess, and it could be anything: for example, that Ortwin, Chris and Erin got kicked out of the Concorde Room for performing Satanic rituals and animal sacrifices while blasting the latest Kanye West album.
