FRS 102 Transition

FRS 102 requires a single transition approach, modified retrospective. Getting the opening balances right is the most important step in your FRS 102 2026 preparation.

A single transition approach

Entities applying the 2026 FRS 102 amendments for the first time use the modified retrospective approach. Unlike IFRS 16, which offered a choice, FRS 102 does not permit full retrospective transition, so comparatives are not restated.

Modified retrospective (required)

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

  • Simpler to apply in practice
  • Comparatives remain on the previous FRS 102 basis
  • Adjustment recognised in opening retained earnings at the date of initial application
  • Additional disclosures required to explain the approach

Full retrospective (not available)

Restating every comparative as if the rules had always applied, as some companies did under IFRS 16, is not an option under FRS 102.

  • Not permitted by the amended FRS 102
  • No need to rebuild schedules back to each lease's commencement
  • Less historical data to gather
  • One consistent method across all preparers

The modified retrospective approach is required because it is simpler and needs less historical data. It is similar to one of the modified approaches that was permitted on transition to IFRS 16.

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:

  • That the modified retrospective approach has been applied
  • 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
