What it means
The cash flow statement is the only one of the three main financial statements that deals purely in money that moved. The profit and loss account contains estimates, accruals and non cash charges, and the balance sheet is a snapshot of values at a single date, but the cash flow statement records what actually entered and left the bank.
That makes it the natural starting point for anyone sceptical about a set of results. The first thing an analyst looks at is the shape of the three sections.
A mature, healthy business typically shows positive operating cash flow, negative investing cash flow as it replaces and expands assets, and negative financing cash flow as it repays debt and pays dividends. A different shape is not automatically bad, but it always deserves an explanation.
The second check is the relationship between operating cash flow and net profit. If cash consistently runs well below profit, cash is being absorbed somewhere, usually in growing receivables or stock, and if the gap widens over several periods it is a genuine warning sign.
Dividing operating cash flow by net profit gives a quality of earnings ratio that many investors treat as a first filter. The third area is capital spending.
Subtracting capital expenditure from operating cash flow gives free cash flow, the money genuinely available for debt repayment, dividends and acquisitions, and it is worth splitting maintenance spending from expansion spending where the disclosure allows. A business whose free cash flow depends on deferring necessary replacement is borrowing from its own future.
Finally, analysis should always cover more than one year. A single period can be distorted by the timing of a large receipt or a delayed supplier payment, so three to five years of the same statement, read side by side, is far more revealing than any single column of figures.
In practice
Real-world examples.
Example
An investor reviewing a fast growing online retailer sees profit rising 40% while operating cash flow falls. The cash flow statement shows stock up $6,000,000, revealing that growth is being bought by filling warehouses rather than by selling more efficiently.
Example
A bank credit team assesses a printing firm whose operating cash flow comfortably exceeds profit every year. The difference is depreciation on presses bought a decade earlier, and the analyst flags that replacement spending will soon reduce free cash flow sharply.
Example
A charity's finance committee compares three years of cash flow statements and finds operating cash flow positive in each year, but only because a restricted grant arrived early in one of them. The committee changes its reporting to show restricted and unrestricted cash separately.
Think of it
“Cash flow statement analysis is studying the cash flow statement to understand financial health.
Formula
Calculation
Quality of earnings ratio = operating cash flow / net profit
Free cash flow = operating cash flow - capital expenditure
Net change in cash = operating + investing + financing cash flows
A home textiles wholesaler reports net profit of $2,000,000 and operating cash flow of $3,000,000 for the year.
The quality of earnings ratio is $3,000,000 / $2,000,000 = 1.5, which means every dollar of reported profit was backed by $1.50 of cash, a comfortable position.
Capital expenditure was $1,200,000, so free cash flow is $3,000,000 - $1,200,000 = $1,800,000. Investing cash flow was -$1,200,000 and financing cash flow was -$500,000 after loan repayments and dividends.
Net change in cash = $3,000,000 - $1,200,000 - $500,000 = $1,300,000. With opening cash of $2,000,000, the closing balance is $2,000,000 + $1,300,000 = $3,300,000.Case study
Seen in the real world.
The following is an illustrative and fictional scenario. Waverly Home Textiles, an invented importer and wholesaler, reported record profits of $2,400,000 and its management team expected a straightforward refinancing. The bank's analyst asked for three years of cash flow statements rather than the summary pack the company usually supplied.
The analysis showed operating cash flow of $2,900,000, $1,600,000 and $300,000 across the three years against rising profits throughout. Receivables had grown from 52 days to 91 days as Waverly chased volume with large retailers on extended terms, and the profit was real but was sitting in customer accounts rather than in the bank.
Waverly's fictional board used the finding to restructure its commercial terms, introducing early settlement discounts and a firm credit limit per account. Two years later profit was slightly lower, operating cash flow had recovered to $2,200,000, and the refinancing completed at a lower margin than the original request.
Watch out
Common mistakes.
- Reading only the closing cash balance at the foot of the statement and ignoring which section produced the movement.
- Celebrating positive operating cash flow that was achieved by stretching suppliers, since delayed payables flatter cash for one period and reverse in the next.
- Analysing a single year in isolation, when the value of the statement comes almost entirely from the trend across several periods.
Questions
People also ask.
Which section matters most?
The operating section, because it shows whether the core business generates cash, and the other two mainly explain what was done with it or how a shortfall was funded.
What does negative investing cash flow mean?
Usually that the company is buying assets, which is normal and often healthy, while persistently positive investing cash flow can mean the business is selling assets to stay afloat.
Is a quality of earnings ratio below 1.0 always a concern?
Not in a single period, especially during rapid growth, but a ratio below 1.0 for three consecutive years usually means profit is not converting into cash and deserves investigation.
