A structure to run business efficiently using practiced methods is always a good thing. However from what little I have understood, the goal of Private Equity is to maximize the dollar value on their investment. Somehow they have settled with the playbook that running a business even profitably isn't the best idea. Instead its much more profitable to take over the struggling business at good price, squeeze everything possible from the assets (thats where PE seem to be investing their expertise unfortunately) over duration of time. Update the books in a manner that it saves money on taxes and carry forwards the loss, making money in the process.
My favorite is to sell the building(s) to their private real estate company and lease back. Then IPO the company and keep the rent coming on a 25 year lease.
