I was waiting for this. What happened is that after 29 years of organic growth under the ownership of the founding family, they sold out to some highly leveraged venture fund. Four years later we were in the depths of the financial crisis and the sell out valuation was obviously ridiculous and the loans that funded the buyout were unsustainable.Bavaria effectively went bust, and their parent company lost around €1bn in a debt-for-equity swap, in 2009.
The high finance people wanted to get the liability cleared off their books so the loans were sold on at 10% of face value. I don't this this counts as an operational crash of the Bavaria business.
