Book Value Per Share, Last Interim Period

What is the definition of BV PS Interim?

Book Value Per Share - or Net Asset Value Per Share - is a measure of shareholder's equity determined on a per-share basis. Book value per share is calculated by subtracting liabilities and the value of any outstanding preferred stock from assets and dividing the remainder by the number of outstanding shares of stock. Book value per share reflects accounting valuation and not necessarily market valuation. However, should the company go into liquidation, the book value per share is a proxy for the value remaining for common shareholders after all debtors are paid.
