Why would they lose their investment
you just told me above they know all about growing the game
listen I’ll give you a tip since you don’t understand, private equity is a terrible way to try and grow a sport
but as a league fan I’m overjoyed Union did this and you can see already it’s impact
I was right you don't understand basic economics.
The Six Nations, like NZR set up a new company. This company controls the revenue that comes from the product, i.e TV rights, sponsorship, ticket sales. That company is then part sold to Private equity and the stake holders of that company take out "dividend" from that sale.
This company is a limited liability company, meaning that only the company is responsible for its debts.
Should this company go bust and the assets are liquidated, the assets being only the intangible tv rights sponsorship contracts and the like, then the shares become worthless. The PE company loses their investment and the countries get to set up a new company to start again at no real loss.
Of course the PE company wants to maximise the return on that investment so they help grow the game.
Like I said, its basic economics, even you should be able to understand that.
