Definition
Book Value per Share (BVPS) is the net accounting value of a company’s assets attributable to each equity share — the “break-up value” if the company were liquidated at recorded balance-sheet values:
Book Value per Share = Total Shareholders’ Equity ÷ Total Shares Outstanding
Total Shareholders’ Equity under Ind AS equals: Equity Share Capital + Securities Premium + General Reserve + Retained Earnings (Surplus) + Other Comprehensive Income (OCI) cumulative balance. OCI includes unrealised gains/losses on FVTOCI equity instruments, remeasurement of defined benefit liabilities, and foreign currency translation differences — making book value more volatile under Ind AS than under predecessor Indian GAAP. Book Value per Share is the denominator in the Price-to-Book (P/B) ratio.
How It Is Computed
From Ind AS financial statements (SEBI LODR 2015 Regulation 34 annual filings):
- Total Shareholders’ Equity: “Total Equity” line from the Ind AS Schedule III balance sheet — use the figure attributable to owners of the parent, excluding non-controlling interest, for per-share computation.
- Total Shares Outstanding: from Statement of Changes in Equity or Schedule of Share Capital in the annual report. Use shares outstanding at period end (not weighted average, unlike EPS).
- Tangible Book Value (TBV): subtract goodwill and other intangibles (Ind AS 103) from Total Equity. Banks and financial analysts prefer TBV because intangibles have uncertain realisable value in a distress scenario.
What High/Low Values Signal
A market-to-book ratio above 1× (market price > book value) is the norm for profitable, growing companies — investors pay a premium for future earning potential above the accountant’s recorded net assets. This gap (the “franchise value” or “intangible premium”) relates to Tobin’s Q ratio (market value of assets ÷ replacement cost) — studied in macroeconomics to measure aggregate investment incentives (Hayashi 1982, Econometrica).
When market price falls below book value (P/B < 1×), the market signals either: (a) book assets are overstated relative to realisable value (common for stressed NBFC/bank loan books), (b) future ROE is expected below cost of equity, or (c) the company is in distress. The historical academic literature (Fama-French 1993) finds such “value stocks” (high book-to-market) earned higher subsequent returns on average — replicated in India by Agarwalla, Jacob & Varma (2014).
Sector Dependency
Book value is most meaningful for asset-heavy sectors where balance sheet assets closely approximate economic value: banks (loan portfolios, investment securities), mining and natural resources (mining rights, reserves), real estate, and capital equipment manufacturers. For asset-light businesses — software, pharmaceutical formulations, branded FMCG — book value severely understates economic value. Human capital, client relationships, and IP are unrecorded at economic value on the balance sheet. P/E or EV/EBITDA is more useful for such companies.
Worked Example
State Bank of India (NSE: SBIN) — FY2025 standalone results (BSE filing, May 2025)
Approximate figures from SBI FY2025 standalone Ind AS annual results:
- Total Shareholders’ Equity (attributable to owners): ₹3,97,000 crore
- Total Shares Outstanding: approximately 892 crore
BVPS ≈ ₹3,97,000 Cr ÷ 892 Cr ≈ ₹445 per share
At approximately ₹810 (NSE, April 2025): P/B ≈ ₹810 ÷ ₹445 ≈ 1.82×
SBI’s P/B of ~1.8× reflects improving ROE (~17–18%), declining NPA ratios, and franchise value of its large branch and customer network. PSU bank sector median P/B is approximately 1.4×; private bank median approximately 2.5–3.5×, illustrating the premium for higher-quality franchises. All figures are approximate; verify with current filings.
Caveats
- OCI volatility: Ind AS FVTOCI adjustments create quarter-to-quarter book value swings without operational meaning — particularly for banks holding large equity investment portfolios. Track “core book value” excluding OCI.
- Historical cost accounting: Assets are carried at historical cost less depreciation, not replacement cost. Old industrial plants may have near-zero book value but substantial replacement cost.
- Goodwill: Post-acquisition goodwill can be a large fraction of equity. Goodwill impairment (Ind AS 36) can instantly destroy book value — highlighting the importance of tangible book value.
- Buybacks: Share buybacks reduce equity and share count simultaneously. EPS and ROE rise; book value per share may rise or fall depending on the relative magnitudes.
