Equity is the residual: Equity = Assets − Liabilities. Presented properly, though, it's a layered history of everything the owners ever put in, everything the business ever earned and kept, and everything ever handed back. Learn to read the layers and the equity section becomes the fastest biography of a company you can find. We'll build it layer by layer, in the order events create them.
How is shareholders equity built, layer by layer?
Layer 1: Share capital (at face value). Every share carries a face value (US: par value), a legal denomination fixed in the charter documents. The share-capital line is simply shares issued and paid up × face value. In India, face values are conventionally ₹10 (the traditional default), ₹2 or ₹1. Companies split ₹10 shares into ₹1 or ₹2 shares as prices rise, to keep the ticket small. Reliance Industries keeps ₹10. TCS, Asian Paints, ITC and HDFC Bank are ₹1, and Infosys is ₹5. US par values are deliberately token. Microsoft's is $0.00000625 per share, and a few cents is typical. Par exists for legal mechanics, not economics.

Three things to hard-wire:
- Face value has nothing to do with worth. MRF's shares have a ₹10 face value and have traded above ₹1,00,000 each (as of mid-2026). MRF has simply never split. A ₹1-face share isn't "cheaper" than a ₹10-face share in any economic sense.
- Indian dividend arithmetic quotes off face value. A "250% dividend" on a ₹10 face value means ₹25 per share. That's 250% of ₹10, not of the market price. On a ₹1 face, a "3,300% dividend" is ₹33 per share. Ignore the theatrical percentages and compute per-share rupees.
- Authorized capital (the ceiling the charter permits) ≥ issued ≥ subscribed ≥ paid-up, which is what's actually on the balance sheet. For healthy listed companies these last three are effectively equal.
Layer 2: Securities premium (India) / Additional paid-in capital, APIC (US) / Share premium (IFRS). Nobody sells shares at face value after day one. When Kaveri Labs issues a ₹10-face share at ₹90, share capital rises ₹10 and securities premium rises ₹80. The premium is real owners' money, usually far larger than share capital itself. Indian company law restricts what it can be applied to (Companies Act 2013, Section 52). The permitted uses are issuing fully-paid bonus shares, writing off share/debenture issue expenses, premium payable on redemption, and funding buybacks. It can't simply be paid out as a dividend. US APIC has no such statutory fence. It's the same economic layer with fewer rules.
Layer 3: Retained earnings (US) / Retained earnings or "surplus" (India). This is the engine room: Closing RE = Opening RE + Net income − Dividends − Transfers to other reserves, give or take a few direct adjustments you'll meet later. It's cumulative since inception. A mature compounder's equity is dominated by this line, because the business has financed itself. Meet a 30-year-old company whose retained earnings dwarf its share capital and premium combined, and you're looking at a self-funding machine. Meet one that keeps issuing fresh shares to grow, and the owners are funding it. Dilution is the price.
What are the reserves in Indian other equity?
Layer 3a: India's reserve family (the "reserves & surplus" zoo). Under Schedule III (Division II), everything except equity share capital is bundled as "Other equity," and the notes break it into named reserves. You need to be able to identify each animal:
| Reserve | Created by | Can pay dividends from it? | What it tells you |
|---|---|---|---|
| Securities premium | Share issues above face | No (Sec 52 uses only) | How much owners paid in above face |
| Retained earnings / surplus | Accumulated profits | Yes (it's the natural source) | The self-funding engine |
| General reserve | Voluntary transfer out of profits (a pre-2013 law required it before paying dividends; now optional) | Yes — it's a "free reserve" | A legacy habit of conservatism; economically identical to retained earnings |
| Capital reserve | Capital-type events, not operations: bargain-purchase gains on acquisitions (the Ind AS carve-out routes these here via OCI), forfeited shares, certain grants | No — not from operations, not distributable | Money that arrived without being earned by the business |
| Capital redemption reserve (CRR) | Statutory transfer (= face value of shares bought back/redeemed) when buybacks are funded from free reserves (Sec 69) | No — locked | The legal footprint of past buybacks |
| Revaluation surplus | Upward revaluation of PP&E via OCI (Ind AS/IFRS option) | No — unrealized | Book value inflated by valuation, not cash |
| Share options outstanding | ESOP expense accumulating until exercise (M1.09) | No | Stock compensation in transit to share capital |
| OCI reserves (FVOCI, hedge, FX translation) | Items parked in OCI (see Layer 5) | No | Unrealized swings held out of P&L |
For analysis, separate free reserves (retained earnings, general reserve) from capital-type reserves (capital reserve, CRR, revaluation surplus). Free reserves are distributable and reflect earned, kept profit. Capital-type reserves aren't. Picture a company boasting "₹5,000 crore of reserves" where half is revaluation surplus. It has earned far less than the headline suggests.
And kill the beginner's misreading now: reserves are not cash. Reserves are on the claims side. They say whose the assets are, not what they are. A company with ₹18,000 crore of reserves may hold ₹400 crore of cash. The rest of the owners' claim is standing in factories, inventory and receivables. Reserves were never a vault, and the money is already at work.
What is treasury stock?
Layer 4: Treasury stock (US), and why India mostly has none. When a US company buys back its own shares and holds them, the cost shows up as treasury stock, a negative (contra-equity) line carried at cost. Coca-Cola is the classic exhibit. Decades of buybacks have built a treasury line around −$52bn against total equity of roughly $25–27bn (illustrative, FY24 scale; pull the 10-K). Treasury shares carry no votes or dividends and can be reissued for ESOPs or acquisitions. Nearly everyone uses the cost method. A par-value method exists, but it's rarely used. Under the cost method, equity falls by the cash paid, and no gain or loss on your own shares ever touches the P&L.
Many US companies instead retire repurchased shares immediately (Microsoft and Apple do), charging the buyback against common stock/APIC and retained earnings. Push that far enough and you get accounting's great party trick. Apple's retained earnings are negative, a deficit of around $19bn (illustrative FY24 scale). The deficit comes from buybacks and dividends exceeding everything Apple ever accumulated, with no losses involved. The balance sheet records financing history, not health.
India runs a different regime. Bought-back shares must be extinguished within seven days of completing the buyback (Companies Act 2013, Sec 68(7)), so there's no warehousing. Share capital shrinks immediately and the CRR transfer from Layer 3a records the retirement. India's one sighting of "treasury shares" is ESOP-trust holdings, which consolidated Ind AS statements deduct from equity, treasury-style.
What other layers sit in equity?
Layer 5: Accumulated other comprehensive income (AOCI). You already know OCI from the income statement. It covers gains and losses that are real but unrealized, or non-operating enough that standard-setters route them around net income. AOCI is where they accumulate on the balance sheet: foreign-currency translation of overseas subsidiaries, fair-value moves on FVOCI investments, cash-flow-hedge reserves, pension remeasurements. Watch the signs. A US multinational after a strong-dollar decade will show deeply negative translation AOCI, because its foreign subsidiaries' equity shrank in dollar terms. Microsoft's AOCI is around −$6bn (illustrative, FY24 scale). India presents the same content as named reserves inside Other equity and has no single AOCI caption.
Layer 6: Non-controlling interest (NCI, formerly "minority interest"). It appears only in consolidated statements. Say the parent owns 75% of a subsidiary. Consolidation puts 100% of the subsidiary's assets and liabilities on the group balance sheet, so the 25% of its equity that belongs to outsiders has to be shown as a claim. NCI is inside total equity but outside "equity attributable to owners of the parent." For per-share arithmetic you use only the parent's slice: Book value per share = Equity attributable to owners ÷ shares outstanding. Full consolidation mechanics, including how NCI is first measured, come in the equity module ahead.
A note on preference shares. Indian company law calls them share capital, but Ind AS/IFRS classify by substance. A redeemable preference share with a mandatory dividend is debt, a borrowing on the balance sheet. Only perpetual, discretionary-dividend preference capital stays in equity. US GAAP similarly pushes mandatorily redeemable preferred toward liabilities. When you see "preference shares," ask whether the company has to pay. If it does, it's debt wearing equity's clothes.
Shareholders equity formula
Here's the whole build on one line:
Total equity = Contributed capital (share capital + premium) + Earned capital (retained earnings + free reserves) + Accumulated OCI − Treasury stock + NCI
