IAS 34: interim financial reporting

Annual accounts tell investors what happened last year. By the time they arrive, the news can be months old. Listed companies therefore also publish short reports during the year, usually every three or six months, so that shareholders can see how the business is doing. International Accounting Standard (IAS) 34, Interim Financial Reporting, sets out what those reports must contain and how the numbers are worked out.

This topic covers the scope of IAS 34, the content and periods of an interim report, the rules for recognition and measurement, how estimates are used, and the Nigerian reporting rules for listed companies set by the Securities and Exchange Commission (SEC). The previous topics covered the standards for annual presentation. The next topic covers related party disclosures.

In November 2025 Question 6(a) the interim reporting rules were tested together with held-for-sale accounting.

Key terms in plain English

Syllabus check

IAS 34 is examinable at this level. It supports Syllabus Area B, item 1(b), on applying IFRS standards to reporting issues, and links to the Nigerian regulatory framework in Area A. This topic covers:

• the objective and scope of interim reporting;
• the minimum content and the periods for which statements are presented;
• recognition and measurement in interim periods, and the use of estimates;
• the quarterly and half-yearly reporting duties of Nigerian listed companies.

CAMA 2020, the SEC and interim reports

The Companies and Allied Matters Act 2020 (CAMA 2020) governs annual statements. Interim reporting by listed companies is mainly a securities law matter, but CAMA 2020 supplies the accounting records and the signing and website duties that sit behind it.

Scope of IAS 34

IAS 1 (and IFRS 18 from 2027) requires statements at least annually. Many companies must report more often, for example half-yearly or quarterly, because a stock exchange or regulator requires it. IAS 34 does not make interim reporting compulsory and does not set the frequency. It sets the form and content. It encourages listed companies to publish an interim report and to file it within 60 days of the end of the interim period.

A company that says its interim report complies with IAS 34 must comply with all of it.

Form and content of an interim report

As a minimum an interim report includes:

1. a condensed statement of financial position;
2. a condensed statement of profit or loss and other comprehensive income, as a single condensed statement or a condensed profit or loss statement followed by a condensed comprehensive income statement;
3. a condensed statement of changes in equity;
4. a condensed statement of cash flows; and
5. selected explanatory notes.

The statement showing profit or loss must also show basic and diluted earnings per share for the period. A company may give a full set of statements if it wishes, and if it does, the full set must comply with IAS 1. The report focuses on new activities, events and circumstances since the last annual statements. It does not repeat information already reported.

Periods to be presented

For a company with a 31 December year end that publishes a half-yearly report to 30 June 2027:

A company that reports quarterly also shows the three-month profit or loss figures for the latest quarter and the same quarter last year, alongside the year-to-date figures. Note that the statement of financial position compares with the last year end, not with the same date last year.

Recognition and measurement

The basic rule is that an interim report is a part of the year, not a separate year. So:

• Same policies. Use the same accounting policies as in the latest annual statements, unless a policy has changed since then.
• Year-to-date measurement. Items are measured on a year-to-date basis. If a company writes inventory down to zero in the first quarter and sells it in the second, the six-month figures show no write-down and the first-quarter write-down is reversed.
• Normal recognition tests apply. An asset or liability is recognised in an interim report only if it meets the definitions and recognition criteria at that date. Costs are not deferred just because they will benefit later in the year.

Interim reporting relies more on estimates than annual reporting does, but the report must still be reliable and relevant.

Interim reporting in Nigeria

Listed companies in Nigeria must also meet the Nigerian Exchange Group (NGX) listing rules and the SEC rules. As the Institute of Chartered Accountants of Nigeria (ICAN) teaches them:

Quarterly reports

• Public quoted companies prepare a quarterly report under International Financial Reporting Standards (IFRS), so IAS 34 applies.
• It is filed with the SEC, and at the same time with the securities exchange and the public, within 30 days of the quarter end.
• It comes with a certification letter signed by the CEO and CFO.
• The notes must cover items such as changes in accounting policy, seasonality, changes in estimates, issues and repayments of debt and equity, dividends, segment information, significant events after the period, business combinations, restructuring, discontinued operations, correction of prior errors, inventory write-downs, impairment and reversals, litigation settlements, debt defaults, related party transactions, and acquisitions, disposals and commitments for property, plant and equipment.
• The signed quarterly statements of financial position, profit or loss and other comprehensive income and cash flows are published in at least one national daily newspaper. The policy notes and other information are put on the company’s website, whose address is shown in the newspaper notice.

Half-yearly returns

Public companies file half-yearly returns with the SEC within 30 days of the half-year end. They cover general information, corporate governance, unclaimed dividends and the audit committee, with an undertaking certifying reliability signed by the company secretary, chief internal auditor, financial controller, managing director, board chairman and chairman of the audit committee.

The rules in more depth

Why year-to-date measurement

If each quarter were measured on its own, a loss in the first quarter that reverses in the second would show up twice and the second quarter would look better than it really is. Measuring from the start of the year means the half-year figures equal what an annual report would show at 30 June.

Why tax uses the expected full-year rate

Tax is charged on annual profit. If profit is lower in the first half and higher in the second, applying each period’s tax separately would give unfair rates. Using the expected annual effective rate spreads tax fairly.

Why development costs cannot be capitalised early

Capitalising costs in anticipation of meeting the criteria would let a company move expenses out of the interim period on a hope. The recognition tests apply on the reporting date, interim or not.

Seasonal businesses

Costs that occur unevenly during the year are not spread or deferred unless the same treatment would be right at year end. The seasonality is explained in the notes instead.

Worked example: interim tax and inventory

1. Expected annual effective tax rate.
   ₦90m ÷ ₦300m = 30%.
2. Interim tax charge.
   ₦120m × 30% = ₦36 million, even if the actual current tax paid on first-half profits looks different.
3. Inventory. Measured year-to-date, the inventory was sold at a profit, so no write-down is needed at 30 June. The first-quarter write-down of ₦5 million is reversed, so the six-month results show none.
4. Policies. Mela uses the same policies as in its last annual statements.
5. Periods presented. Statement of financial position at 30 June 2027 and 31 December 2026. Profit or loss, changes in equity and cash flows for six months to 30 June 2027 and 2026.
6. Nigeria. As a listed company, Mela files a quarterly report within 30 days of each quarter end with the CEO and CFO certification letter, and posts the notes on its website (consistent with s. 374(6) and s. 405 of CAMA 2020).

How to score full marks

• Open with the IAS 34 rules. Same policies, year-to-date measurement. In Question 6(a) of November 2025, these earned the first 1.5 marks.
• List the five condensed components and mention earnings per share.
• Give the periods in a table. The statement of financial position compares with the last year end. The others compare with the same period last year.
• Use the right estimate rule for each item. Tax at the expected annual rate, pension roll-forward, provisions updated without an expert.
• For Nigerian questions, give 30 days, the CEO and CFO certification, newspaper publication and website notes.
• If a question mixes standards, apply IAS 34 first and then the other standard for the numbers. The Lawson question needed held-for-sale accounting, which a later topic covers.

Common mistakes in the exam

• Saying IAS 34 requires companies to report quarterly or half-yearly. It does not set the frequency.
• Comparing the interim statement of financial position with the same date last year. It compares with the last year end.
• Measuring a quarter on a stand-alone basis instead of year-to-date.
• Capitalising development costs that do not yet meet the criteria.
• Applying the interim period’s actual tax instead of the expected annual rate.
• Ignoring the Nigerian requirement for the CEO and CFO certification.
• Giving a full set of statements and saying it complies with IAS 34 without applying IAS 1.

Quick revision

• IAS 34 sets content, not frequency. File within 60 days (encouraged).
• Condensed: financial position, profit or loss and other comprehensive income (OCI), changes in equity, cash flows, selected notes, plus earnings per share.
• Same policies. Year-to-date. Normal recognition tests.
• Intangibles: normal criteria. Tax: expected annual rate. Pension: roll forward. Provisions: update without expert. Inventory: estimates.
• Nigeria: quarterly report within 30 days, CEO and CFO certification, newspaper and website. Half-yearly returns within 30 days.
• CAMA 2020: ss. 374(1), 374(6), 377, 378, 405.
