FRS 102 debt modifications: Common accounting pitfalls and what finance teams need to know

In an environment of higher borrowing costs, refinancing activity and evolving lender relationships, many businesses are renegotiating their debt arrangements.

Whether a company secures an extension to its repayment schedule, amends interest terms, capitalises interest through payment-in-kind (PIK) arrangements, or undertakes a broader refinancing exercise, the accounting consequences can be significant. Yet debt modifications remain one of the most misunderstood areas of UK GAAP.

Why debt modifications matter

Businesses often renegotiate borrowing arrangements to support growth, preserve liquidity or respond to changing market conditions. Common changes include extending loan maturities, revising repayment schedules, deferring or capitalising interest, and amending covenant terms.

While these changes may make commercial sense, they can result in unexpected accounting consequences under FRS 102, and, in some cases, lead to unexpected gains or losses in the profit and loss account.

The key question: Is the modification substantial?

The first step is determining whether the modification is substantial or non-substantial, as this drives the accounting treatment.

Unlike IFRS 9, FRS 102 does not provide a detailed definition of what constitutes a substantial modification. Instead, companies are required to apply professional judgement and develop an approach that is reasonable and applied consistently. This flexibility can be useful, but it also creates risk if a clear accounting policy has not been established.

Can companies use the IFRS 9 10% test?

In practice, many finance teams look to IFRS 9 for guidance.

Under IFRS 9, entities often compare the present value of cash flows before and after the modification, discounted using the original effective interest rate. If the difference exceeds 10%, the modification is generally considered substantial.

While this approach is widely used, FRS 102 does not require it. The 10% test is often adopted because it provides a structured framework that is familiar to auditors, lenders and other stakeholders, but it is not mandatory.

Whatever methodology is chosen, consistency is key.

Accounting for a substantial modification

Where a modification is assessed as substantial, the original liability is generally treated as having been extinguished and replaced with a new financial liability.

This can lead to derecognition of the original debt, recognition of a new financial liability and a gain or loss being recorded in profit or loss. Any related fees are usually expensed as part of the transaction.

For some businesses, the impact on reported results can be more significant than expected.

Accounting for a non-substantial modification

Where the modification is not considered substantial, a different accounting treatment typically applies.

Instead of derecognising the original liability, the carrying value of the debt is adjusted to reflect the revised cash flows. Any resulting modification adjustment is recognised through profit or loss, while fees are generally amortised over the remaining loan term.

Although the accounting may appear simpler, careful modelling is still required to ensure the revised carrying amount is calculated appropriately.

Five common debt modification mistakes

1. Treating the IFRS 9 10% test as mandatory

One of the most common misconceptions is that the IFRS 9 approach must be applied under FRS 102. This is not the case. FRS 102 allows companies to develop their own reasonable and consistently applied methodology.

2. Ignoring changes in instrument classification

A modified loan may not necessarily remain within the same FRS 102 category.

For example, a loan previously classified as a “basic financial instrument” under Section 11 may, following modification, contain features that require treatment under Section 12 as a more complex financial instrument.

This issue is frequently overlooked.

3. Incorrect treatment of fees

Transaction fees can materially affect the outcome of modification calculations.

Failure to properly incorporate fees and costs can lead to incorrect conclusions regarding the significance of the modification and the resulting accounting treatment.

4. Missing embedded derivatives

Restructured lending arrangements sometimes introduce features such as conversion rights, contingent returns or other embedded derivative characteristics.

Where present, these may require separate accounting consideration. Failing to identify them can result in material financial reporting errors.

5. Inadequate disclosures

Even where the accounting treatment itself is appropriate, disclosures relating to modified debt are often insufficient.

Investors, lenders and auditors increasingly expect clear explanations regarding the nature of modifications, the judgements applied and the resulting accounting impacts.

Looking beyond the accounting entry

The effects of a debt modification rarely stop at the loan balance itself.

Changes can have a knock-on impact on profitability, net assets, distributable reserves, covenant calculations, business valuations and going concern assessments. In some cases, these wider consequences can be more significant than the initial accounting adjustment.

For that reason, finance teams should consider the impact across the entire financial model, rather than focusing solely on the accounting treatment at the modification date.

What auditors focus on

During an audit, debt modifications often attract significant scrutiny because they involve complex judgements and potentially material financial statement impacts. Areas frequently challenged include:

• The substantial versus non-substantial assessment
• Selection of discount rates
• Calculation methodology
• Treatment of fees
• Instrument classification
• Assessment of embedded derivatives
• Adequacy of disclosures

Robust documentation is therefore essential.

How Gravita can help

Our accounting advisory and audit specialists regularly assist clients with loan restructurings, refinancing projects, shareholder and convertible loan amendments, debt-for-equity transactions and covenant renegotiations.

We help finance teams navigate complex technical requirements while ensuring the accounting outcome reflects the commercial substance of the arrangement. Just as importantly, we work with businesses early in the process so potential accounting impacts can be understood before revised terms are agreed.

Thinking about modifying your borrowings?

Before signing revised loan terms, it is worth taking the time to understand the accounting implications. A change that makes sense commercially can sometimes have an unexpected effect on profits, distributable reserves, banking covenants or financial statement disclosures.

At Gravita, we regularly advise businesses, lenders and finance teams on debt restructurings, refinancing arrangements and loan modifications under FRS 102. Our experience shows that even seemingly simple amendments can give rise to complex accounting judgements with far-reaching consequences.

If you’re considering modifying your borrowing arrangements, our technical accounting team can help you assess the impact and avoid surprises further down the line.
