Bain effectively risked nothing to make a killing and ensure Toys-R-Us would eventually file for bankruptcy due to an unsustainable debt load. Banks are happy to loan Bain money for these schemes because Bain makes a killing on them and private equity almost always finds a sucker dumb enough to buy the zombie company off them. (Every once in a while the zombie goes south so fast private equity is left holding the bag).
For loans to the zombie company the terms are punishing enough the bank only needs the zombie to survive for a limited amount of time.
The part I don't understand yet is who is the dumb money buying shares in these hollowed-out debt-laden husks from the private capital vultures? It almost always ends up badly. Even when it doesn't the upside isn't great.
FWIW Guitar Center is almost certainly headed for the same end and for the same reason.
Is this based on reliable statistics or on highly visible anecdotes? Perhaps the "dumb money" isn't as dumb as you think.
Note - not all PE firms do this (big or small) but it is a common strategy that does earn them money.
The junior debt, of course, has nothing pledged to back it at all. Junior debt in leveraged buyouts is pure gambling.
The people who issued the debt (made loans to the company to buy back its outstanding shares) are sophisticated investors who saw the balance sheets of the company and thought they were likely to get paid back. If things had worked out, they'd have made an above-market interest rate. They also knew what would happen if things didn't work out (the present situation is a typical downside for LBO capital). They didn't lose all their money -- they made 7.375% interest for 15 years. If they get 50% of the capital back through bankruptcy, that's a total return of 160%. Not the worst investment over the last 15 years, though obviously Apple would have been better.
This is a variant of the 80s era stuff in the movie Wall St. When WalMart was expanding regional players like Ames, Jamesway, etc would do this. You could tell when it was happening because the stores would be stuffed to the brim with stuff before the bankruptcy.
