When a company transitions from IFRS to FRS 102 (typically due to de-listing or voluntary change), significant balance sheet restatements often occur. This guide covers the major accounting policy changes, the "deemed cost" option, and audit considerations.

Why Transition from IFRS to FRS 102?

Key point: Transition requires restatement of comparative financial statements to FRS 102 basis. This is material accounting policy change; full year-on-year comparison required.

Major IFRS to FRS 102 Changes

1. Property, Plant & Equipment (Most Material)

IFRS Approach:

FRS 102 Approach:

Transition Mechanics:

Use deemed cost election: treat revalued IFRS amount as deemed cost at transition date (no reversal of prior revaluation gains). Going forward, depreciate the deemed cost balance.

Example: Building originally cost £5m (IFRS), revalued to £8m (IFRS). At FRS 102 transition (1 Jan 2026):
— Deemed cost = £8m (the revalued IFRS amount)
— Accumulated depreciation reset to £0
— Going forward, depreciate £8m over remaining useful life
— Revaluation gain of £3m retained in equity (not reversed)

2. Investment Property

IFRS Approach:

FRS 102 Approach:

Transition Decision:

If no active market, FRS 102 allows cost model. Write-down IFRS fair value to cost (often a significant loss).

3. Leases (Major Change)

IFRS 16:

FRS 102:

Transition Impact:

De-recognize IFRS 16 ROU assets and lease liabilities; reverse to expense treatment. Often reduces reported assets significantly.

Lease impact (typical): Company with £20m ROU asset + £18m lease liability (IFRS 16). Upon FRS 102 transition, de-recognize both. Report lease payments as operating expense instead. Balance sheet shrinks; P&L more volatile (but normalized over years).

4. Deferred Tax

IFRS:

FRS 102:

Transition:

If transitioning to SE status, de-recognize all deferred tax (material P&L benefit in transition year).

5. Financial Instruments

IFRS 9:

FRS 102:

Transition Reclassification:

Transition Year Adjustments (Summary)

Typical P&L Impact (First FRS 102 Year)

Item Impact
Lease de-recognition (operating lease) Increases profit (ROU asset/liability reversed; lease now expense)
Deferred tax de-recognition (if SE) Increases profit (DTA loss reverses)
Investment property fair value →’ cost Decreases profit (write-down loss)
Revaluation asset use of deemed cost Neutral (no immediate impact; affects depreciation going forward)

Audit Red Flags: IFRS to FRS 102 Transition

Red Flag 1: Deemed Cost Not Used for Revaluations

Finding: Revalued IFRS assets reversed to original cost at transition (incorrect).

Auditor action: Use deemed cost (retain revalued amount); adjust for depreciation only.

Red Flag 2: Leases Not Reclassified

Finding: IFRS 16 ROU assets retained in balance sheet under FRS 102 (unsupported lease classification).

Auditor action: Assess operating vs finance lease status; de-recognize if operating; adjust balance sheet.

Red Flag 3: Comparatives Not Restated

Finding: First FRS 102 year (2026) presented under FRS 102; prior year comparatives still under IFRS.

Auditor action: Restate comparatives to FRS 102 basis; reconcile transition differences.

Red Flag 4: Investment Property Fair Value Retained Despite No Market

Finding: Property valued at IFRS fair value (£5m) despite no active market; FRS 102 allows cost method, but cost is £3m.

Auditor action: Determine if active market exists; if not, use cost method; write down to £3m; recognize loss.

Real-Life Case Study: Moving From IFRS to FRS 102

Scenario. A subsidiary previously consolidated under group IFRS switches to standalone FRS 102 to cut reporting cost.

On transition. It prepares an opening balance sheet at the transition date, applying FRS 102 retrospectively but using the available transition exemptions. The biggest adjustment: capitalised development costs and certain fair-value gains treated differently, plus reinstating goodwill amortisation. Each change is explained in a transition reconciliation.

Takeaway. Transition is not a fresh start, it is a retrospective restatement with targeted exemptions, and it requires reconciliations of equity and profit from the old to the new framework so users can see the effect of the switch.
