The Business Price Has a Margin of Safety Compared to the Business Value

The business price in this equation, has a margin of safety compared to the business value. When i put em in, i'm looking for 50 % discount. I don't think warren buffet uses fty % any more. But i've seen berkshire step in and start buying companies with less than a 50%. In fact, just recently they started buying more bank of america. And there's no way that's out of 50 % margin of safety right now, in my opinion. So when you do this, just make sure that you are getting a large enough margin of safety that you feel confident in buying the company.
