Net-net versus double net
Net-net investing is frequently confused with "double net," which is another important term for some investors. However, the two couldn't be more different in meaning, even if they look the same on the surface.
Net-net investing involves buying an undervalued stock for less than its liquidation value; "double net" is a common lease for real estate investment trust (REIT) investors to encounter. In a double net lease, the tenants pay their rent plus their portion of the property taxes and insurance on the portion (or entire) building they've leased.
How to perform a net-net calculation
Determining whether or not a company is a good target for a net-net strategy is pretty simple if you have a short list of companies. All you need is the current stock price of the company, the value of its current assets, the value of its total liabilities, and the total number of shares it has issued.
