FRS 102 Transition

Choosing the right transition approach — and getting the opening balances right — is the most important step in your FRS 102 2026 preparation.

The two transition approaches

Entities applying the 2026 FRS 102 amendments for the first time must choose one of two transition methods. The choice affects comparatives, disclosure requirements, and the complexity of the transition calculation.

Full retrospective

Apply the standard as if it had always been in effect. Restate all comparative periods presented in the financial statements.

  • Provides full comparability
  • Requires historical lease data going back to commencement
  • More complex and time-consuming
  • Opening adjustment recognised in retained earnings at the earliest period presented

Modified retrospective

Recognise the cumulative effect at the transition date only. No restatement of comparatives.

  • Simpler to apply in practice
  • Comparatives remain under old FRS 102
  • Adjustment recognised in opening retained earnings at transition date
  • Additional disclosures required to explain the approach

Most entities are expected to choose the modified retrospective approach. It is simpler, requires less historical data, and is consistent with how most entities applied the equivalent IFRS 16 transition.

Modified retrospective: practical expedients

Under the modified retrospective approach, a number of practical expedients are available to reduce the transition workload:

  • Use of hindsight: when determining the lease term for contracts that contain options, entities may use hindsight — i.e. they can assess the option in light of facts and circumstances that exist at the transition date rather than at the original commencement date.
  • Single discount rate: entities may apply a single discount rate to a portfolio of leases with reasonably similar characteristics (e.g. similar remaining terms, similar asset classes, similar currencies), rather than determining a rate for each individual lease.
  • Short-term and low-value exemptions: leases that would qualify as short-term or low-value under the new standard do not need to be recognised on the balance sheet at transition.
  • Operating leases previously disclosed: the opening lease liability can be measured at the present value of the remaining lease payments, discounted at the IBR at the transition date — rather than requiring a full reconstruction from the original commencement date.

Opening balance calculation

Under the modified retrospective approach, the steps to calculate opening balances at the transition date are:

  1. Identify all in-scope leases as at the transition date
  2. For each lease, determine the remaining lease payments including any escalation
  3. Apply the incremental borrowing rate at the transition date to discount those payments to present value — this gives the opening lease liability
  4. The ROU asset is typically set equal to the opening lease liability (adjusted for any prepayments or accruals relating to the lease)
  5. Deferred tax is recognised on any temporary difference between the carrying amounts of the ROU asset and lease liability where applicable
  6. The net difference is recognised as an adjustment to opening retained earnings

Required disclosures at transition

The financial statements for the first period of adoption must include:

  • The transition method applied (full or modified retrospective)
  • Any practical expedients used
  • The weighted average IBR applied at the transition date
  • A reconciliation of operating lease commitments previously disclosed to the opening lease liability recognised
  • The carrying amounts of ROU assets and lease liabilities at transition
