The headline of the article is actually to some extent misleading, because it does not indicate, that the proposal was turned down, but that is mentioned in the article. And yes, depending on the structure, this could really move the needle for BRK.
I also find the article interesting, because the content of the article gives some indication of, what's passing the desks of Mr. Buffett and Mr. Munger of potential stuff. This is [was?] huge.
This could not take place without the involvement of both BRK at top level and the 3G people. Those 3G people are really into the space of huge deals now.
