LEARN THE BASICS
Cash versus earnings: trace the bridge
Learn how working capital, noncash charges, and classification choices can separate net income from operating cash flow.
Begin with reconciliation, not a slogan
Under the indirect method, the operating section starts with net income and adjusts for noncash items and changes in operating assets and liabilities. Depreciation is added back because it reduced accounting income without using current-period cash. An increase in receivables commonly reduces operating cash flow because recognized sales have not all been collected.
Treat working capital as operating context
Inventory purchases can use cash before products are sold. Deferred revenue can bring cash in before revenue is recognized. Payables can temporarily preserve cash when suppliers have not yet been paid. These movements may reflect growth, seasonality, bargaining power, or stress; the direction alone does not identify the cause.
Separate recurring operations from financing
Debt issuance and stock issuance appear in financing cash flow, not operating cash flow. Selling property appears in investing cash flow even if it raises total cash. Free cash flow is a calculation, not a standardized GAAP subtotal, so compare definitions before comparing companies.
Look across compatible periods
One quarter can be distorted by annual bonuses, tax payments, inventory builds, or customer collection timing. Compare the same seasonal period and use several years when available. Then ask whether the balance-sheet changes and note disclosures support the explanation.
A worked example
A hypothetical company earns $120, records $30 of depreciation, sees receivables rise by $50, inventory rise by $20, and payables rise by $10. With no other adjustments, operating cash flow is $90.
| Bridge item | Cash-flow effect | Running total |
|---|---|---|
| Net income | Starting point | $120 |
| Depreciation | +$30 | $150 |
| Receivables increase | −$50 | $100 |
| Inventory increase | −$20 | $80 |
| Payables increase | +$10 | $90 |
The illustration omits taxes, stock compensation, deferred taxes, acquisitions, currency effects, and many other adjustments. Strong operating cash flow is not automatically sustainable, and weak operating cash flow is not automatically evidence of manipulation.
Questions to take into a report
- Which adjustments are noncash and which reflect timing?
- Are the working-capital movements seasonal or unusual?
- Does the company’s free-cash-flow definition match mine?
