I generally feel like leveraged buyouts for numbers into the billions are just inside jobs for those selling.
Stay with me for a sec.
So the seller makes a closed door deal with the "buyer" to funnel money back to them personally after the sale is done. So in this case, say, they commit 3.6bn to the "buyers" and pocket 3bn for themselves. Almost the entire purchase is leveraged, with the expectation that it will become unsustainable and go bankrupt shortly after the purchase.
The buyers don't really give a shit, they'll write it off, collect whatever they can from insurance, etc. They didn't really want to company anyways, so they let it fold.
The money they took home from the deal with the seller is entirely theirs, the company bears the weight of the debt and the consequences of defaulting on the debt, so the execs that made the move are basically free and clear.
Everyone wins, except, you know, the poors who work at the purchased company, the banks, who don't give a shit, and insurance people, which... Nobody gives a fuck about them...
At the end of the day, the execs of the purchasing company get rich, the sellers get rich, and that's the fucking point.
If the sellers instead just closed up shop, they would get maybe a fraction of the money they would from selling it, mainly in selling off assets... It would be a pittance compared to this scheme.
All they need to do is find someone they can buy out the morals of, to complete the deal. This is surprisingly easy in the corpo world.
