The cash flow statement: where the money went

Cash flow splits movement of money into three activities: operating (running the business), investing (buying or selling long-lived assets and investments) and financing (debt and equity: borrowing, repaying, issuing shares, paying dividends).

A healthy mature company usually shows positive operating cash, negative investing cash (it is investing), and financing that is either modestly positive (raising capital) or negative (returning it).

Accounting books a sale when it is earned rather than when the money lands. Revenue can rise while cash sits in receivables, and reported profit can rise while inventory swallows the cash.

The cash flow statement is the check on the income statement: it strips out non-cash accounting entries and shows what actually arrived.

Operating cash flow minus capital spending is free cash flow (FCF), the cash genuinely available to pay down debt, buy back shares, pay dividends or reinvest.

FCF is harder to dress up than earnings, which is why many investors treat it as the more honest bottom line.

Repeated years of reported profit with negative operating cash flow, funded by new shares or new debt, is the classic pattern behind most accounting blow-ups.

It does not prove anything is wrong: some fast-growing businesses consume cash by design. It does mean that the business model depends on continued financing.
