Cash flow statement

The cash flow statement is one of the three core financial statements. It tracks every cash inflow and outflow that occurred during a defined accounting period, a quarter or a full year. Where the income statement measures profitability and the balance sheet measures financial position, the cash flow statement measures liquidity: the actual movement of cash through the business.

It's structured into three sections. Operating activities comes first and captures the cash generated or consumed by the core business, starting from net income and adjusting for non-cash items like depreciation and amortisation and for changes in working capital. Investing activities comes second and records cash spent on or received from long term assets, primarily capital expenditure, acquisitions, and disposals. Financing activities comes last and covers cash flows between the company and its capital providers, including debt issuances and repayments, equity raises, share repurchases, and dividends paid.

Each section isolates a different dimension of cash behaviour: operating cash flow reveals whether the business model itself generates cash or consumes it, investing cash flow reflects the intensity of capital deployment, and financing cash flow shows how the company is managing its capital structure and returning value to shareholders. Free cash flow, one of the most widely used metrics in financial analysis, is derived from this statement as operating cash flow less capital expenditure.

Unlike the balance sheet, which is a snapshot, the cash flow statement covers a span of time and measures flows, and unlike the income statement, it's largely immune to accrual accounting judgments: revenue recognition timing and depreciation policy affect reported earnings but don't change cash. Capitalisation decisions are the main exception: capitalising a cost leaves total cash unchanged but moves the outflow from operating to investing activities, which lifts operating cash flow. Even so, it remains the most difficult statement to manipulate and the most trusted signal of underlying economic performance.

It's the essential complement to the income statement. When the two diverge, a company reporting strong earnings but weak operating cash flow, it's almost always a signal worth investigating. Experienced analysts treat the gap between net income and operating cash flow as one of the most informative figures in the entire set of financial statements.
