Reading Financial Statements: Balance Sheet, Income & Cash Flow

A company reports a record profit and runs out of money in the same year. That isn't fraud and it isn't rare — it's what happens when you read one statement and skip the other two, because profit and cash are genuinely different things.

Three statements, three different questions

The balance sheet is a photograph taken on one date: everything the company owns, everything it owes, and the difference between them. It has no duration — it describes an instant, which is why it's always dated rather than given a period.

The income statement covers a stretch of time — a quarter or a year — and reports revenue minus expenses to arrive at net income. This is where 'profit' lives, and it is built on accounting rules about when revenue counts as earned and when a cost counts as incurred.

The cash flow statement covers the same stretch and tracks only money that actually moved, sorted into operating, investing and financing activities. It exists precisely because the income statement's judgements can drift a long way from the bank balance, and it's the one experienced readers open first.

The equation that has to hold

Assets = Liabilities + Shareholders' Equity. This is an identity rather than a finding — it balances by construction, which is where the balance sheet gets its name.

Read it as a sentence about funding. Everything the company owns had to be paid for somehow, and there are exactly two sources: money borrowed from lenders, and money belonging to owners. The equation just says those add up.

Rearranged, it's more useful: Equity = Assets − Liabilities. That's the residual claim owners have if everything were sold and every debt settled. It's also called book value, and it's what the price-to-book ratio in the next lesson compares a share price against. Note that it can be negative, and a company with negative equity is not necessarily failing — years of buybacks can produce it.

Why cash flow is the honest one

Revenue is generally recorded when it's earned, not when the customer pays. That's a reasonable rule, and it opens a gap: a company can book a large sale, report the profit, and be holding an invoice rather than money.

The gap appears on the balance sheet as accounts receivable and on the cash flow statement as an outflow adjustment. So a business whose net income is healthy while operating cash flow is negative is usually one whose customers haven't paid — which may be a timing quirk, or may be revenue recognised too aggressively, or customers who cannot pay.

Any single quarter can diverge innocently. A persistent gap across several periods is the signal, and it's the reason 'earnings quality' is a phrase at all. Cash is the hardest number in the filings to shade, because it either arrived or it didn't.
