What is a cash flow statement?
Short answer: A cash flow statement explains the change in cash and cash equivalents during a reporting period. It classifies cash flows as operating, investing or financing activities and reconciles opening cash to closing cash.
Operating activities generally arise from the company's main revenue-producing activities. Investing activities include acquiring or disposing of long-term assets and investments. Financing activities change contributed equity and borrowings. The categories answer different questions: whether operations produce cash, how much the company reinvests, and how capital providers fund or withdraw cash.
Direct and indirect operating cash flow
The direct method shows major classes of operating cash receipts and payments. The indirect method begins with profit and adjusts for non-cash expenses, non-operating items included in profit, and movements in operating assets and liabilities. An increase in trade receivables usually reduces cash relative to revenue because recognised sales have not yet been collected. An increase in trade payables usually increases cash relative to expense because payment has been deferred.
The statement ends with cash and cash equivalents that reconcile to the statement of financial position, subject to required disclosures such as foreign exchange effects and components of cash. Cash equivalents are short-term, highly liquid investments meeting the applicable definition. A bank balance is not automatically available cash if it is restricted.
Example
A company starts the quarter with 600 of cash and reports profit before tax of 1,050. To derive operating cash under the indirect method, finance adds back 240 of depreciation, deducts a 300 increase in receivables, deducts a 150 increase in inventory and adds a 110 increase in payables. It then deducts 180 of tax paid. Operating cash flow is 770: 1,050 + 240 - 300 - 150 + 110 - 180. The company spends 500 on equipment, receives 400 from a new loan and repays 120 of principal. Net cash increases by 550 because 770 - 500 + 400 - 120 equals 550. Closing cash is therefore 1,150. A separate reconciliation confirms that amount against the balance sheet.
How it is interpreted
Operating cash should be analysed across several periods. A strong month can result from collecting old invoices, reducing inventory or delaying suppliers rather than from improved current trading. Capital expenditure should be separated between maintenance, growth and acquisitions where reliable records allow. Financing inflows improve cash but create repayment, interest or ownership consequences that the statement alone does not measure.
Why it matters in financing and a sale
Management uses cash flow to plan payroll, suppliers, investment and funding. Lenders compare recurring cash generation with interest, scheduled principal and covenant requirements. Investors and buyers test whether earnings convert to cash, whether working capital is sustainable and how much capital expenditure is needed to maintain operations. The analysis often feeds a debt-capacity assessment and a valuation bridge.
Classification risks and qualifications
A frequent analytical error is calling loan proceeds operating cash. Other pitfalls include treating EBITDA as cash flow, overlooking restricted balances, omitting cash paid in an acquisition, or reading a working-capital release as permanent performance. Classification rules differ across accounting frameworks, including for interest and dividend cash flows. The example above starts with profit before tax and assumes the related financing effects are treated consistently; a statutory statement must use the starting point and classifications required for its reporting period and framework. For IFRS reporters applying IFRS 18, which is effective for annual reporting periods beginning on or after 1 January 2027 with earlier application permitted, related IAS 7 amendments require operating profit as the indirect-method starting point and change interest and dividend classifications, with specific rules for entities whose main business activities involve investing or providing financing to customers. US GAAP requirements differ. Significant non-cash transactions are excluded from cash movements but may require disclosure. Local law and loan documents can impose additional reporting definitions.
