The statement of cash flows reports every movement in a company's cash, cash equivalents and restricted cash over a reporting period, sorted into three sections. It is also the statement professionals get wrong most often. Audit Analytics ranked cash flows the fourth most-cited accounting issue in US restatements from 2003 to 2022, and the most-cited issue among large accelerated filers.
Those three numbers frame the whole topic. The format looks mechanical, the reporting practice is nearly uniform, and the rules underneath are about to move. Most textbooks in circulation this year still teach the pre-amendment version.
What Is the Statement of Cash Flows?
It is the reconciliation between accrual profit and actual cash. The income statement records revenue when earned. The statement of cash flows records money when it moves. The gap between those two is the entire point of the document.
Two standards govern it. ASC 230 in US GAAP, issued as SFAS 95 in 1987 and not substantially revised since. IAS 7 in IFRS.
Both require the statement to explain the change in cash and cash equivalents. Cash equivalents means short-term, highly liquid holdings with an original maturity of three months or less. Since ASU 2016-18, US filers must also show the change in restricted cash and restricted cash equivalents inside that same total.
The bottom line of the statement is not a performance measure. It is a reconciling figure that must tie exactly to the movement in the cash line on the balance sheet.
What Do the Three Sections Show?
Operating covers the trading cycle. Investing covers long-term assets. Financing covers capital providers. Classification is where marks and restatements are lost, because several common items sit on a boundary and the correct side differs by standard.
The boundary column is not a list of edge cases invented by lecturers. The FASB issued ASU 2016-15 specifically because eight classification questions had no clear answer in US GAAP, including debt prepayment penalties and proceeds from insurance settlements.
That update took effect for public business entities in fiscal years beginning after 15 December 2017. Private entities followed a year later.
How Do You Build One?
You need three inputs. Two consecutive balance sheets, one income statement, and the notes covering disposals, revaluations and dividends. Everything else is derived.
Start with the operating section under the indirect method. Take the profit figure, then reverse every item inside it that did not move cash, and every item that moved cash into a different section.
Three adjustment families cover almost all of it. Non-cash charges such as depreciation, amortisation and impairment get added back. Gains and losses on asset disposals get reversed, because the real cash appears in investing. Working capital movements get applied by direction: inventory up means cash down, payables up means cash up.
Notice that profit of 84,000 produced 98,000 of operating cash. A company can also run the reverse. Rising profit with falling operating cash is the pattern that tells you receivables or inventory are absorbing everything the income statement reports.
Investing and financing are simpler because they are built from gross movements rather than reconciliations. Reconstruct each non-current asset account and each borrowing account from opening balance, additions, disposals and closing balance. The missing figure is your cash flow.
AskSia exists for exactly this kind of problem: one where the answer sits across a balance sheet, an income statement, three notes and a lecture slide, and no single source contains it. Attach all of them, and the workspace cross-references rather than making you hold four documents in your head at once.
Why Do Most Firms Choose Indirect?
Both standard setters prefer the direct method. ASC 230-10-45-25 encourages it. Almost nobody uses it.
One caution about that split, because almost every article repeating it omits the provenance. The familiar "98% use indirect" line traces to survey research from the 1990s and to Krishnan and Largay's 2000 study, not to a current census. ICAEW restated the position in 2025 in softer terms: the vast majority of US companies and apparently a majority of IFRS entities use the indirect method.
The direction is not in doubt. The precision is.
For coursework this matters in a practical way. Exams still test both, because the direct method forces you to convert each income statement line to a cash basis, which is the harder skill even though it is the rarer practice. The financial accounting cheatsheet keeps both formats side by side for revision.
What Changes Under IFRS 18?
The IASB issued IFRS 18 in April 2024. It replaces IAS 1 and amends IAS 7, and it applies to annual periods beginning on or after 1 January 2027. Application is retrospective, so comparatives from 2026 must be restated.
Two changes hit the cash flow statement directly.
First, the indirect method no longer starts from profit before tax. It starts from the new operating profit subtotal that IFRS 18 requires on the face of the income statement. Second, the accounting policy choices for interest and dividends are removed.
The final column carries an exception worth knowing. Entities whose specified main business activity is lending, investing or insurance classify interest and dividend flows according to that activity, which pushes them into operating for a bank. Your first-year unit will almost certainly set questions on the general case.
Meanwhile the FASB has a live project on targeted improvements to ASC 230, aimed at reorganising the statement for financial institutions and adding a disclosure about cash interest received. A separate research project on broader improvements remains on its agenda, including whether some digital assets qualify as cash equivalents.
Where Do Students Lose Marks?
Sign errors dominate. An increase in a current asset is a cash outflow, and an increase in a current liability is a cash inflow. Reverse either one and the reconciliation still looks plausible but fails to tie.
Reconstruction is the second. Questions rarely hand you disposal proceeds. They give an opening carrying amount, a closing carrying amount, depreciation for the year and a gain or loss, and expect you to derive the cash. That is precisely the skill the Monash ACX2100 module names in its title, and the same skill the ACX2100 unit breakdown flags as the highest-weighted exam component.
Non-cash transactions are the third. A bonus issue, an asset acquired under a lease, or debt converted to equity never touches the cash statement, but both ASC 230 and IAS 7 require disclosure of them.
The fix is repetition under time pressure rather than re-reading the chapter. Build a Flashcards deck from the classification table above so the operating-investing-financing call becomes automatic, then run Mock Exam mode on full reconstruction questions with the clock on. If a specific adjustment keeps failing, the accounting workspace will re-explain it against your own worked attempt rather than a textbook example.
Frequently Asked Questions
What is a cash flow statement with an example?
A cash flow statement reports the change in cash across three sections. The worked reconciliation above shows the operating section in full: profit of 84,000, depreciation added back at 26,000, a disposal loss reversed at 4,000, and working capital movements of negative 18,000, positive 11,000 and negative 9,000, producing net operating cash of 98,000. Investing would then show the actual disposal proceeds and any asset purchases. Financing would show share issues, dividends paid and borrowing movements. The three subtotals combine to the net change in cash, which must equal the difference between the opening and closing cash balances on the balance sheet. If it does not tie, one item has been classified twice or omitted. Use that tie-out as your first check on every practice question before you review individual lines.
How do you write a cash flow statement?
Work from two consecutive balance sheets, the income statement for the period, and the notes on disposals, leases and dividends. Under the indirect method, open with profit, add back non-cash charges such as depreciation and impairment, reverse gains and losses on asset disposals, then apply working capital movements by direction. Build investing and financing by reconstructing each account: opening balance, plus additions, less disposals or repayments, equals closing balance, with the cash figure as the missing number. Under IFRS from 1 January 2027 your starting point becomes operating profit rather than profit before tax. Finish by confirming the net change equals the movement in cash on the balance sheet, then add the required disclosure of non-cash transactions. Practise the reconstruction step separately from the reconciliation step, because most marks are lost in reconstruction.
What are the five rules of cash flow?
No standard publishes a list of five rules, so treat any article offering one as a teaching device rather than authority. What ASC 230 and IAS 7 actually impose are five decisions. Which balances count as cash, cash equivalents and, for US filers since ASU 2016-18, restricted cash. Which of the three sections each flow belongs to. Whether operating cash is presented by the direct or indirect method. How interest and dividends are classified, which becomes prescriptive under IFRS from 2027 rather than a policy choice. And which material non-cash transactions require separate disclosure. Every exam question tests one or more of those five, in some combination. Check your unit's prescribed standard before answering a classification question, since the correct side of the line differs between US GAAP and IFRS on interest and overdrafts.
Where can I find a statement of cash flows?
For a listed US company, open its Form 10-K on the SEC's EDGAR database and go to the financial statements section, where the statement of cash flows follows the income statement and balance sheet. Quarterly figures appear in Form 10-Q. Companies reporting under IFRS publish it in their annual report, usually as the third or fourth primary statement. Both formats show three years of data for annual filings, which lets you compare operating cash against reported profit over time rather than in a single period. For coursework you rarely need a live filing. Set questions supply the underlying balance sheets and notes instead, because the assessed skill is construction rather than retrieval. If your unit asks you to analyse a real filer, pick one from your own market so the standard matches what you have been taught.
What is the purpose of the statement of cash flows?
Its purpose is to show what accrual accounting hides. Revenue is recognised when earned, not when collected, so a business can report growing profit while cash drains into receivables and inventory. The statement makes that visible by separating trading cash from investment and financing activity. Standard setters treat it as important enough to keep revising: the FASB has a live targeted-improvements project on ASC 230, and the IASB amended IAS 7 through IFRS 18 with effect from 1 January 2027. The SEC's Chief Accountant devoted a formal statement to it in December 2023, noting that preparers and auditors do not always apply the same rigour here as to other statements. For revision, pair this statement with the accrual concepts in your first-year unit rather than studying it in isolation, since every adjustment traces back to an accrual rule. Students preparing for credit-by-exam routes can start with the CLEP financial accounting syllabus outline.
It reports movement, not quality. A company can post strong operating cash by stretching suppliers or selling receivables, and neither shows on the face of the statement.
It is also period-bound. Timing near a reporting date shifts a flow from one year to the next without any economic change.
And its classification is only as reliable as the judgement behind it, which is the honest reading of the restatement data at the top of this article. ASC 230 is principles-based, so preparers make calls, and calls can be wrong. Treat cash flow figures as a starting question rather than a verdict, and check the notes on non-cash transactions before drawing any conclusion from a subtotal.
