The cash flow statement

Profit is an opinion formed under rules. Cash is a fact about a bank account. That is an overstatement, and it is close enough to be the most useful sentence in this subject.

The three sections

Cash from operating activities. Money generated by the business doing its job. Starts from profit before tax and adjusts back to cash: adding non-cash charges like depreciation, removing items belonging elsewhere like interest, and adjusting for working capital changes.

Cash from investing activities. Buying and selling long-term assets — capital expenditure, acquisitions, purchases and sales of investments. Usually negative for a growing company, and that is healthy.

Cash from financing activities. Dealings with lenders and owners — borrowing, repaying, paying interest and dividends, issuing or buying back shares.

The three sum to the change in cash on the balance sheet.

Why it is harder to arrange

The judgements that shape profit — when revenue is recognised, how long an asset lasts, what provision is adequate — have far less grip on cash.

A company can recognise revenue on goods shipped to a distributor who has not paid. Profit rises. Cash does not. The difference is sitting in receivables on the balance sheet, visible to anyone comparing the two statements.

That gap can persist for a while. It cannot persist indefinitely, because eventually the receivable is collected or written off, and the write-off is the reckoning. Which is why the most useful habit in this subject is a multi-year comparison:

Over five years, how much did the company report as profit, and how much cash did operations actually produce?

A business where the second is consistently well below the first is reporting profits it is not collecting. It may be growing fast — chapter 11 — or it may have a problem. Either way you now know to ask.

Free cash flow

free cash flow = cash from operations − capital expenditure

Cash left after keeping the business running and investing in it. This is the number that could, in principle, be paid out, used to repay debt, or reinvested at the owners' discretion. Chapter 20 builds valuation on it.

One honest difficulty: capital expenditure includes both maintenance (replacing what wore out) and growth (new capacity). A company spending heavily on growth has low free cash flow and may be doing exactly the right thing. Companies rarely split the two, so free cash flow is most useful across several years and alongside chapter 9's returns on capital — which say whether the spending is earning anything.

Reading the pattern

The three sections together describe a company's stage and health better than any single ratio.

Operating	Investing	Financing	What it usually means
Positive	Negative	Negative	Mature and healthy: generating cash, investing, returning the rest
Positive	Very negative	Positive	Growing: generating cash but raising more to expand faster
Negative	Negative	Positive	Early stage or in trouble: burning cash and funding it externally
Positive	Positive	Negative	Possibly selling assets to pay down debt — worth understanding why

None of these is automatically good or bad. The third describes a startup and also a failing company, and the difference is whether the burn is buying something. But each raises a different question, and that is what you want from a first read.

Three specific checks

Interest paid against finance costs. The income statement's finance cost is accrual; interest paid in the cash flow statement is cash. A persistent gap means interest is being accrued and not paid, or capitalised into assets.

Tax paid against tax expense. Same logic. Large deferred tax means the accounting charge and the cash are diverging.

Dividends paid against profit. Whether distributions are covered by what the business actually generated, which is chapter 3 of the equity subject's payout ratio in cash terms.

The order to read in

Start here, not with profit.

If operating cash flow is healthy and roughly tracks profit over several years, the income statement can be trusted and you can proceed. If it does not, everything else in the accounts needs reading sceptically — because the one number that is hard to arrange is disagreeing with the one that is not.

The point

Cash either arrived or it did not, which makes this statement the hardest to arrange. Compare profit with operating cash flow over five years, not one. Free cash flow is operations less capital expenditure, and the pattern across the three sections tells you which kind of company you are looking at.
