Machines that create value need money before the value shows up: shelves stocked before customers pay, a decade of drug research before the first prescription. Opportunity arrives bigger than the founder's savings, so businesses raise outside money. Every rupee raised, anywhere on earth, takes one of two forms:
What are the two claims on a business?
- Debt, a fixed claim. The lender is promised, say, 10% a year and the money back. Boom or stumble, the promise is the same, and it is paid first, on pain of default.
- Equity (ownership), the residual claim. The owner gets whatever is left after suppliers, employees, the taxman, and lenders. No promises, no ceiling, no floor above zero. Equity eats last, and sometimes eats extraordinarily well.
Hold on to that. Debt is fixed, and equity is the residual, forever. Problem 2 will make you feel how differently the same bakery year lands on each claim. All of Phase 1's accounting is, in one sense, bookkeeping of what belongs to which claim. The balance sheet's Assets = Liabilities + Equity is this paragraph written as an equation.

What is a joint-stock company?
Then came the invention that changed everything. The joint-stock company splits ownership into thousands, today billions, of identical transferable shares. It had three consequences:
- Big pools of capital. No single fortune could fund a railway or a semiconductor fab. Ten thousand small fortunes can.
- Limited liability. A shareholder can lose only what they paid, and creditors can't come after your house. Without this, no sane stranger would buy a sliver of a business they don't control.
- Separation of ownership and management. Owners hire managers, which is wonderfully efficient and permanently dangerous, because managers may serve themselves. File this away, because question 3 exists to deal with it.
A little history to hang it on. The English East India Company (1600) and the Dutch VOC (1602) were the first great joint-stock enterprises, and the VOC's freely traded shares in Amsterdam make it the modern ancestor of every listed company. The Buttonwood Agreement of 1792 seeded the NYSE. Bombay's banyan-tree brokers formalized in 1875 into today's BSE, Asia's oldest exchange. The NSE brought fully electronic nationwide trading from 1994. DMart trades on NSE and BSE, and Costco on Nasdaq. It's the same 400-year-old idea.
