- The notes to the accounts often hold the details that matter, including related-party transactions, contingent liabilities and going-concern statements.
- Auditor changes, qualified opinions, late filings and changes of accounting period are signals to examine, and each can have an innocent explanation.
- Comparing filings across years and group companies, and recording what was filed and when, turns a set of documents into usable evidence.
A set of annual accounts is written to meet a legal obligation. Its authors decide what to include within the limits the rules allow, and the rules for smaller companies often require very little. The primary statements give totals. The detail, where there is any, sits in the notes, in the auditor's report and in the record of when and how the documents were filed. Reading a filing well means reading those parts closely and asking what the figures imply about the business.
The notes to the accounts
The notes are where obligations and relationships are disclosed, and they repay slow reading.
- Related-party transactions. Sales, purchases, loans and guarantees involving directors, shareholders or companies under common control can show where value moves and who benefits.
- Contingent liabilities. Guarantees, pending litigation and claims that have not yet crystallised may matter more than anything on the balance sheet.
- Going concern. A statement that the company depends on the continued support of a shareholder or lender identifies that dependence, and a material uncertainty disclosed by the directors or the auditor deserves attention.
- Events after the balance sheet date. Disposals, refinancings, the loss of major contracts and changes of ownership after the year end are often disclosed here first.
- Directors' loans and intercompany balances. Amounts owed to or by directors and group companies can be large relative to the business and can move in ways the main figures do not explain.
Signals in the filing record
The history of a company's filings can say as much as their content. A change of auditor may follow a fee dispute, a group reorganisation or a routine tender, and it may also follow a disagreement. A qualified opinion means the auditor found a material problem in part of the accounts, or could not obtain enough evidence on it. An adverse opinion or a disclaimer of opinion signals something more serious. An emphasis of matter paragraph leaves the opinion unmodified while drawing attention to an issue the auditor considers fundamental to understanding the accounts. In each case the wording should be read in full, because it usually explains the issue.
Late filing is another signal. It can reflect illness, a change of accountant or simple disorganisation. It can also reflect difficulty in agreeing the figures. A change of accounting period, particularly one that extends the period or is repeated, can delay the point at which results must be published. Each of these merits a note and a question. None of them is a finding on its own.
When the figures and the story disagree
A company's stated activity should be visible in its numbers. A business that describes itself as a manufacturer should show stock, plant and staff costs of some kind. A trading company should show a cost of sales that bears a sensible relationship to turnover. A consultancy with substantial revenue and no employees, or a holding company with large receivables from parties it does not name, raises questions that the filing does not answer.
Comparisons sharpen these questions. Figures for several consecutive years show trends, sudden changes and reclassifications. Filings by companies in the same group should broadly reconcile, so that a balance owed by one company appears as a balance due to another. Differences in year end, currency or timing can explain small gaps, and larger ones need an explanation. Directors and addresses shared across companies can also point to related entities that the accounts do not name.
An anomaly in a filing is a question to be answered, and it is rarely an answer in itself.
Interpreting with care
Most anomalies have a possible innocent explanation. Accounts are prepared under different frameworks, and businesses restructure for tax, financing and administrative reasons that are entirely proper. In some jurisdictions small companies may keep the profit and loss account off the public record and may be exempt from audit, although such exemptions are being narrowed in some places. Availability also differs widely between countries. In some, private company accounts are public. In others, little is filed or access is restricted, and conditions can change. Reading a filing in its legal and local context is part of reading it correctly.
The filing record should be captured as it stood. Note the date each document was filed, the period it covers, whether it was later amended or replaced, and the date of access. A later reader may need to know what was on the public record at a particular time, and registries sometimes correct or remove documents.
We read filings as evidence of what a company chose to disclose, and when. We look for the points where disclosures, timing and figures do not fit together, and we test those points against other sources before drawing any conclusion. Where an anomaly remains unexplained, our reports describe it precisely and set out what further work would resolve it.
