Net Book Value

In accounting, an asset's original price minus depreciation and amortization. For example, if a company bought piece of technological equipment for $100,000 with an absolute physical life of ten years and a patent lasting 20 years, one would account the net book value as the original price and subtract $10,000 per year (for depreciation due to reduced physical life) and $5,000 per year (for amortization).

In accounting a company, the net book value is the value of the company's assets minus the value of its liabilities and intangible assets. Put another way, the book value is the shareholders' equity, or how much the company would be worth if it paid of all of its debts and liquidated immediately. It is also known as the written-down value.
