Assets - Liabialities = Net worth. Assets could include intagible assets though. Intangibles are something that you cannot touch. For example, the Lee Haney "name" may be valued at $6M. Could he go to the bank and hand over his name for $6M? Obviously not.
Not to downplay the success of Lee Haney, just saying fiancial terms can be misleading. Since intangibles are not a hard asset, their value is strictly a valuation based on opinion.
I worked for a company that had to write down their asset value by $1B becasue their earning power in the market had declined, therefore, lowering the valuation of thier intangible.
