What book value per share means
Book value per share estimates the common shareholders’ accounting equity represented by each share. It can help compare a company’s balance-sheet value over time, although market value can differ substantially from book value.
How book value per share is calculated
TickerStat calculates book value per share as SEC-reported common shareholders’ equity divided by reported period-end common shares. Preferred equity is subtracted when separately reported, and basic weighted-average shares are used only when period-end shares are unavailable. Fiscal periods can differ from calendar years, so exact period-end dates are included.
