A valuation of an investment company's shares calculated by subtracting any liabilities from the market value of the firm's assets and dividing the difference by the number of shares outstanding. This factor illustrates the amount a shareholder would receive for each share owned if the fund sold all its assets (stocks, bonds, and so forth) at their current market value, paid off any outstanding debts with the proceeds, and then distributed the remainder to the stockholders. In general, net asset value per share is the price an investor would receive when selling a fund's shares back to the fund. Net asset value per share is similar in concept to book value per share for other types of firms.
