Prothena Corporation plc Book Value 2011-2026 | PRTA

Book value is a financial metric that reflects the value of a company's assets minus its liabilities as of a specific date, according to accounting records. In simple terms, it is the amount that would remain for the owners of the company if all assets were sold and all debts paid off.

What is included in book value

Assets — all company resources: real estate, equipment, inventory, cash, accounts receivable, and others.
Liabilities — all debts and financial obligations: loans, accounts payable, taxes, and other obligations.

Features of the metric

Assessment of the company's "real" value
Book value shows how much the company is worth according to accounting data, that is, the value of its property taking debts into account.
Comparison with market capitalization
Comparing book value and the market price of shares helps to understand whether the company is overvalued or undervalued by the market.
Indicator of financial stability
If the book value is high, it indicates the company has significant assets, which reduces risks for investors.
Key component for financial ratios
Many metrics, such as the price-to-book ratio (P/B), use book value to analyze the attractiveness of shares.
