I'd add that it's also a function of revaluing the assets, and then determining if the return on asset value is appropriate.
Take a small restaurant. Grandad bought the building 50 years ago. That's long since paid off.
The restaurant makes say 10k a month. Good honest business. But the building/land is worth say a million.
The owners don't care, it's paid off. The business makes a good living.
So I come along and offer 500k for the business. That's basically 4 years profit up front. They want to retire soon, so that's good deal. But I turn around and sell the land for a mil. I've made a big profit, and since rent is now 10k, in only a few months the restaurant goes under.
The root problem is that the business is delivering a really poor return on asset value. Which opens the door to someone buying the assets, not the business.
