Calculate the book value per share, a valuation ratio that measures the amount of common equity value per share outstanding.
The book value per share is a fundamental valuation metric that reflects the net worth of a company attributed to each outstanding share of common stock.
The formula is as follows:
\[\text{Book Value per Share} = (\text{Total Shareholder Equity} - \text{Preferred Stock}) / \text{Weighted Average} (\text{Diluted}) \text{Shares}\]Also known as: BVPS, net asset value per share.
