In business, net worth (sometimes called net liabilities) is the total assets minus total outside liabilities of an individual or a company. For a company, this is called shareholders' preference and may be referred to as book value. Net worth is stated as at a particular year in time. In the case of an individual, the term estate is used in relation to deceased individuals in probate. For businesses, the term is used in the context of fraudulent law and on the dissolution of the company.
Net worth in business is generally based on the value of all assets and liabilities at the carrying value which is the value as expressed on the financial statements. To the extent items on the balance sheet do not express their true (market) value, the net worth will also be inaccurate.
Net worth in this formulation is not an expression of the market value of the firm: the firm may be worth more (or less) if sold as a going concern.
On reading the balance sheet, if the accumulated losses exceed the shareholder's equity, it is a negative value for net worth.
