Net current asset value (NCAV) is Benjamin Graham's conservative estimate of a company's liquidation value, first described in Security Analysis (1934). Unlike working capital or net working capital, which subtract only current liabilities from current assets, NCAV subtracts a company's *total* liabilities — current and long-term — from its current assets. The result approximates what would be left for shareholders if the company's current assets (cash, receivables, inventory) were liquidated at book value and every liability, including long-term debt, was paid off in full, before assigning any value at all to fixed assets, intangibles, or the business as a going concern.
Graham used NCAV as the basis for his "net-net" investing strategy: buying stocks trading at a market capitalization below their NCAV, on the theory that the market price offered a margin of safety even if the business itself never generated another dollar of profit. A company can have positive working capital while still failing the NCAV test, since NCAV also has to absorb the company's long-term obligations.
NCAV per share divides this figure by shares outstanding, making it directly comparable to the stock's trading price — a company trading below its NCAV per share is, by this measure, priced below its liquidation value.
