IFRS 1 First-time Adoption of IFRS

IFRS 1 governs the very first set of financial statements an entity prepares under IFRS. Its aim is a transparent, comparable starting point: it requires you to apply IFRS as if you always had — with a defined set of exemptions and exceptions to keep the exercise practical. This guide covers the transition date, the opening balance sheet, the reconciliations and the common exemptions.

When IFRS 1 applies

IFRS 1 applies to an entity's first IFRS financial statements — the first annual statements in which it makes an explicit and unreserved statement of compliance with IFRS. It applies once. After that, ordinary IFRS and IAS 8 govern subsequent changes.

The transition date and the opening statement of financial position

Two dates frame the exercise. The reporting date is the end of the first IFRS reporting period. The date of transition to IFRS is the beginning of the earliest period for which full comparative information is presented — usually one year earlier, giving one comparative year.

At the date of transition the entity prepares an opening IFRS statement of financial position. This is the launch pad for everything that follows, and preparing it means:

  • recognising all assets and liabilities that IFRS requires;
  • derecognising items that IFRS does not permit as assets or liabilities;
  • reclassifying items from their previous-GAAP category to the category IFRS requires; and
  • remeasuring all recognised items in accordance with IFRS.

The net effect of these adjustments is recognised directly in retained earnings(or, where appropriate, another category of equity) at the transition date — not in profit or loss — because they relate to events before the entity moved to IFRS.

Reconciliations — the heart of the first IFRS report

To let users understand how the change affected the numbers, IFRS 1.24 requires the first IFRS financial statements to include reconciliations from previous GAAP to IFRS:

  • a reconciliation of equity at two dates — the date of transition, and the end of the latest period presented in the entity's most recent annual previous-GAAP statements;
  • a reconciliation of total comprehensive income for the latest period in the entity's most recent annual previous-GAAP statements.

The reconciliations must give enough detail to understand the material adjustments. If previous GAAP errors are identified in the process, they are distinguished from changes in accounting policy. Together these reconciliations are typically the most scrutinised part of a transition.

The general rule and its two categories of relief

The default is full retrospective application of the IFRS in force at the reporting date. Because that can be onerous or even impossible, IFRS 1 provides two kinds of carve-out:

  • Mandatory exceptions — areas where retrospective application is prohibited because it would rely on hindsight. These include estimates (your IFRS estimates at the transition date must be consistent with the estimates made under previous GAAP, unless there is objective evidence of error), and certain aspects of derecognition, hedge accounting and non-controlling interests.
  • Optional exemptions — reliefs an entity may elect to reduce cost. Common ones are described next.

Common optional exemptions

  • Deemed cost — measure an item of property, plant and equipment (or certain intangibles and investment property) at its fair value at the transition date and use that as deemed cost, avoiding a full retrospective cost reconstruction. A previous-GAAP revaluation can also serve as deemed cost.
  • Business combinations — elect not to restate combinations that occurred before the transition date, freezing the previous-GAAP carrying amounts (subject to specified adjustments and an impairment test of goodwill).
  • Cumulative translation differences — reset the foreign currency translation reserve to zero at the transition date, so only post-transition differences are tracked.
  • Leases — practical reliefs on applying IFRS 16 at transition; and exemptions covering share-based payments, borrowing costs and decommissioning liabilities, among others.

Each exemption is a genuine policy choice with consequences for the opening numbers and future depreciation or amortisation, so they are chosen deliberately and disclosed.

Presentation and additional disclosures

Beyond the reconciliations, IFRS 1 asks for enough explanation for users to understand the move to IFRS. If deemed cost is used for items of property, plant and equipment, the entity discloses, for each such line item in the opening statement, the aggregate of those fair values and the aggregate adjustment to the carrying amounts reported under previous GAAP. Where an entity presents an interim report under IAS 34 for part of its first IFRS year, comparable reconciliations are provided there as well.

The first IFRS statements present at least one year of comparatives on a full IFRS basis, and the accounting policies used are applied consistently across all periods presented — the opening balance sheet, the comparative year and the first IFRS reporting year — using the IFRS effective at the reporting date, even where some of those requirements were not yet mandatory in the earlier periods. That consistency is what makes the comparatives genuinely comparable.

How it connects

First-time adoption is the moment your reporting shifts onto the IAS 1 framework, and the practical accounting differences it surfaces are set out in the IFRS versus local GAAP guide. If your group crosses a control threshold on adoption, pair this with IFRS 10 consolidation.
