FRS 102 vs IFRS: Intangible Asset Rules

Introduction

UK companies face a consequential choice in how they account for intangible assets. UK-listed groups must report under IFRS (specifically IAS 38 for intangible assets and IFRS 3 for business combinations). Private companies, charities, and smaller groups can choose FRS 102, the UK's own GAAP framework designed to be proportionate to entity size while maintaining reporting quality.

The differences between FRS 102 and IFRS in treating intangible assets are not trivial. Goodwill treatment — amortised under FRS 102 versus annually impairment-tested under IFRS — is perhaps the most well-known divergence and has direct implications for reported profits, balance sheet values, and PE exit planning. But the differences extend further: intangible asset recognition in business combinations, development cost treatment, and useful-life rules all diverge in ways that affect financial outcomes.

For UK SMEs planning for growth, investment, or exit, understanding these differences is not academic — it shapes reporting choices that may affect valuation multiples, investor perception, and tax efficiency.

Goodwill Treatment: The Defining Difference

FRS 102: Amortisation

Under FRS 102 Section 19, goodwill arising from a business combination must be amortised over its useful life. If the useful life cannot be reliably estimated, FRS 102 caps it at 10 years. There is no option to not amortise.

Impact: Goodwill amortisation charges reduce reported profits each year in a predictable, straight-line pattern. This provides earnings smoothing and a tax shield (goodwill amortisation is typically tax-deductible). Many private equity owners prefer this approach because it creates a defined, predictable P&L impact rather than the cliff-edge risk of impairment.

IFRS: Annual impairment testing

Under IFRS, goodwill is not amortised. Instead, it must be tested annually for impairment (under IAS 36) by comparing the carrying amount of the cash-generating unit (CGU) to its recoverable amount.

Impact: No amortisation charge reduces reported profits — earnings appear higher. However, impairment is a binary risk: the goodwill balance sits on the balance sheet unchanged until a sudden, potentially large write-down. This creates earnings volatility and can trigger covenant issues if impairment is substantial.

Business Combinations

Intangible asset recognition

The recognition test itself differs. FRS 102 requires an acquired intangible to meet both tests before separate recognition is mandatory, with an option to recognise those meeting only one; IFRS 3 requires recognition when either test is met. The 2024 FRS 102 Periodic Review left this test unchanged. IFRS 3 also provides significantly more guidance on identifying and separately recognising intangible assets. In practice, an IFRS 3 PPA will typically identify more intangible assets and less goodwill than a FRS 102 Section 19 PPA for the same transaction.

Development Costs

Both frameworks allow capitalisation of development costs under conditions:

The practical difference is subtle but important: IAS 38 makes capitalisation mandatory when criteria are met, while FRS 102 allows more judgement in determining when the threshold is crossed. Some FRS 102 reporters choose a more conservative approach, expensing development costs that might be capitalised under IFRS.

Revaluation

Both frameworks offer a revaluation model, and in both it is rarely used, because few intangible assets trade in an active market. Freely transferable licences and quotas are the usual examples; patents, brands and customer relationships almost never qualify.

Impairment

Impairment reversal: now aligned

FRS 102 once allowed a goodwill impairment to be reversed in limited circumstances. The 2015 amendments to FRS 102, which followed the Companies Act changes implementing the EU Accounting Directive, removed that option. Under both frameworks a goodwill impairment is now permanent, while an impairment of another intangible asset can be reversed if the reasons for it no longer apply.

Useful life: the difference that remains

FRS 102 treats every intangible asset as having a finite useful life (18.19). Where the life cannot be reliably estimated, it may not exceed 10 years (18.20). IAS 38 allows an indefinite useful life where there is no foreseeable limit to the period of benefit (IAS 38.88); such an asset is not amortised but is tested for impairment every year.

Choosing Between Frameworks

Factors favouring FRS 102

• Private company not planning a near-term listing
• PE ownership preferring predictable goodwill amortisation
• Cost sensitivity — FRS 102 compliance is generally less expensive
• Development cost policy — the choice to expense development costs remains available
• Simplicity — fewer intangible assets to identify and value in PPAs

Factors favouring IFRS

• Listed company (mandatory for UK group accounts)
• International investor base expecting IFRS comparability
• Preparing for listing or cross-border M&A within 2-3 years
• International subsidiaries already on IFRS
• Growth company wanting to capitalise development costs (mandatory under IAS 38)

Practical Example: PE Exit Planning

A PE fund acquires a UK mid-market services company for £60 million, with £25 million allocated to goodwill. The fund plans a 5-year hold period before exit.

Under FRS 102 (5-year useful life estimate)

Total P&L impact: £25 million of amortisation charges over the hold period. In a share purchase, this consolidated goodwill attracts no corporation tax relief, so the charge reduces reported profit without reducing tax.

Under IFRS (no amortisation, annual impairment test)

Reported earnings are £5 million higher each year (no amortisation). Goodwill sits on the balance sheet at £25 million. If the business performs well, no impairment triggers — but the risk of a sudden write-down always exists.

Transition Considerations

Companies transitioning from FRS 102 to IFRS (e.g., ahead of a listing) must consider:

• Goodwill: Under the IFRS 1 business-combinations exemption that most companies use, goodwill is carried forward at its FRS 102 carrying amount and amortisation stops. It must be tested for impairment at the transition date and every year after.
• Intangible assets: May need to identify and recognise additional intangibles that were subsumed in goodwill under FRS 102.
• Development costs: Capitalisation becomes mandatory (not discretionary) when IAS 38 criteria are met.

These transition adjustments can materially change reported assets and equity, and should be planned well in advance of the transition date.

Conclusion

FRS 102 and IFRS represent different points on the simplicity-versus-comparability spectrum. For UK private companies, FRS 102 offers pragmatic simplicity with the strategic advantage of goodwill amortisation. For listed companies and those preparing for listing, IFRS provides the international comparability and detailed intangible asset recognition that the capital markets expect.

The right choice depends on the company's current size, ownership structure, growth trajectory, and likely exit route. For related comparisons, see IAS 38 vs ASC 350 for the IFRS vs US GAAP perspective, and IFRS 3 vs ASC 805 for PPA-specific differences.
