A lot of comments praising this summary, but I'll criticize it: it's still too verbose, and misses the point. Meta wants to fund this project, but doesn't want the debt on own its books (because it would impact its vanity AA credit rating). Debt investors are happy to finance a special purpose vehicle guaranteed (in a non debt way) by Meta at a credit rating almost as good as Meta's (say, A). No one is confused this…
So… ‘vanity’ ratings… what’s the point of them then.
So if a company drops their AA rating it could force them out of a lot of funds and investment vehicles.
This complicated vehicle where the debt and assets are in another LLC isn’t actually tricking anyone in finance. If you’re reading about it from blogs then it’s already common knowledge. The structure isn’t actually a one way trick, it’s a set of tradeoffs and protections for the company. They probably could have achieved better terms going direct but with higher risk.
