ACCA FR: The Bonus Issue vs Rights Issue Mistake in EPS Calculations

Earnings per share questions in ACCA Financial Reporting (FR) are supposed to be a reliable source of marks: the formula is simple, and the technique is examinable in a very consistent way sitting after sitting. Yet a specific error keeps showing up in examiner feedback — candidates apply bonus issue treatment to a rights issue, or rights issue treatment to a bonus issue, and lose marks on a question that should have been a comfortable pass. Understanding exactly why these two share capital events are treated so differently under IAS 33 Earnings Per Share is the fix, and it is worth mastering properly rather than half-remembering under exam pressure.

The underlying EPS mechanics are covered in more general depth in our practical guide to IAS 33; this post focuses specifically on where bonus and rights issue adjustments get confused, because that confusion is a distinct and very fixable exam-technique problem within the wider EPS topic. For the full ACCA Financial Reporting syllabus context, EPS sits within the financial statement analysis and reporting requirements at Applied Skills level.

Why the two events are not treated the same way

The basic EPS calculation divides profit attributable to ordinary shareholders by the weighted average number of ordinary shares in issue during the period. The whole point of that weighting is to fairly reflect how much shareholders' capital actually contributed to the period's earnings — shares issued for cash part-way through the year are only weighted for the portion of the year they were outstanding, because the company only had the benefit of that additional capital for part of the year.

A bonus issue (also called a capitalisation issue or scrip issue) breaks that logic completely, because no new resources come into the business at all. Existing shareholders simply receive additional shares in proportion to their existing holding, funded out of reserves — the company is not richer, and shareholders have not put in a cent of new money. Because nothing real has changed except the number of shares in issue, IAS 33 requires the bonus issue to be treated as if it had always existed, for every period presented in the financial statements, with no time-weighting whatsoever.

A rights issue is different in substance, because it does raise new cash — but not at full market value. Shares are offered to existing shareholders below the current market price, which means every rights issue is really two things bundled together: a genuine issue of shares at fair value, and a bonus element hidden inside the discount. IAS 33 requires that bonus element to be stripped out and adjusted for in exactly the same retrospective way as a pure bonus issue, while the genuine capital-raising element is time-weighted in the normal way, because that portion did bring real new resources into the business partway through the year.

The bonus issue treatment

For a bonus issue, IAS 33 requires two things candidates commonly forget to do together:

• Apply the bonus issue to the weighted average number of shares for the current period as though the additional shares had been in issue for the entire year — there is no need to time-weight based on the actual date the bonus shares were issued.
• Restate the comparative (prior year) EPS by applying the same bonus fraction retrospectively, so the prior year figure is presented on a like-for-like basis with the current year. Skipping this restatement is one of the most frequent marks lost on this topic, because it is easy to treat the bonus issue as a current-year-only adjustment.

The logic is straightforward once you separate it from the rights issue mechanic: since no new resources were raised, there is nothing to time-weight, and since the number of shares has permanently changed, every period shown needs to reflect that new share count — otherwise you would be comparing this year's earnings, spread over more shares, against last year's EPS calculated on the old, smaller share count, which would understate the apparent improvement or decline in performance.

The rights issue treatment

A rights issue takes more steps, and this is where the second common mistake appears — candidates remember to time-weight but forget the bonus fraction adjustment, or apply the bonus fraction to the wrong part of the calculation. The standard sequence is:

• Calculate the theoretical ex-rights price (TERP) — the theoretical price of a share immediately after the rights issue, based on a weighted combination of the number of shares held before the issue (at the actual market price) and the new shares issued (at the discounted rights price).
• Derive the bonus fraction, calculated as the actual cum-rights market price divided by the TERP. This fraction isolates the “free” bonus element embedded in the discounted rights price.
• Apply the bonus fraction to the shares in issue before the rights date, then combine this with the actual number of shares in issue after the rights date, time-weighted for the portion of the year each was outstanding — because the new shares genuinely did raise cash and were only in the business for part of the year.
• Restate the comparative EPS by multiplying the prior year's reported EPS by the same bonus fraction — the rights issue equivalent of the bonus issue restatement above, and just as often forgotten.

In short: a rights issue needs both techniques applied together — the bonus-style retrospective adjustment for the discount element, and ordinary time-weighting for the genuine new-capital element — while a bonus issue needs only the retrospective adjustment, with no time-weighting at all.

A quick way to check which treatment applies

Before doing any arithmetic, ask a single question: did the company receive new cash at full market value, or not? If the answer is no — nothing was received, or shares were issued below fair value — a bonus-style retrospective adjustment applies to that element, full stop. If the answer is yes and the shares were issued at fair value, ordinary time-weighting applies with no bonus fraction needed at all. A rights issue sits in between, because it is genuinely both at once, which is exactly why it requires the TERP and bonus fraction step rather than one treatment or the other. Reading the question carefully for the phrase “rights issue” versus “bonus issue” or “capitalisation issue” sounds obvious, but under exam time pressure it is precisely the distinction that gets skipped — leading candidates to default to whichever technique they practised most recently rather than the one the question actually describes.

This same discipline of checking the underlying substance before applying a standard, rather than pattern-matching to the most recently practised technique, is worth building generally in FR — our piece on common IFRS 15 five-step model errors covers a very similar exam-technique trap in revenue recognition.

FAQ

Do I ever need to time-weight a bonus issue?

No. A bonus issue is applied retrospectively to the whole of every period presented, with no time-weighting, because it does not raise any new resources — it only changes the number of shares representing the same underlying equity.

What happens if a rights issue and a bonus issue both occur in the same period?

Work through them in the order they occurred, applying the appropriate technique to each — the bonus fraction adjustment for the rights issue's discount element, and the straightforward retrospective adjustment for the bonus issue — and make sure the comparative EPS is restated for both events, not just one.

Why does the comparative EPS need restating at all if the prior year's figures were already correct at the time?

Because EPS is a trend indicator, and comparing this year's EPS (calculated on the new, larger share count) against last year's EPS calculated on the old share count would distort the trend. IAS 33 restates the comparative so both years are presented on a consistent share-count basis, giving a meaningful like-for-like comparison.
