IFRS 1: First-time Adoption of International Financial Reporting Standards

The ‘OBJECTIVE’ of IFRS 1 is to Ensure that an Entity’s first IFRS financial statements, and its Interim financial reports for part of the period covered by those ‘Financial Statements‘, contain high quality information.

International Financial Reporting Standards

Standard · IASB Issued 2003 · Last Amended 2024  |  Effective for annual periods beginning on or after 1 January 2004

IFRS 1 establishes the procedures an entity must follow when it adopts International Financial Reporting Standards (IFRS) for the first time as the basis for its general-purpose financial statements.

The standard’s central requirement is straightforward: a first-time adopter must apply IFRS in full, retrospectively, as if it had always used the standards with specific, carefully bounded exemptions and exceptions to manage cost and practicability.

The result is financial statements that are transparent, comparable across entities and periods, and provide a faithful starting point for IFRS reporting going forward.

Applicability

Scope of IFRS 1

IFRS 1 applies to an entity whose first IFRS financial statements are its initial annual financial statements in which it explicitly and unreservedly states compliance with IFRS. An entity qualifies as a first-time adopter if, and only if, it did not present IFRS-compliant financial statements in the immediately preceding period.

Typical scenarios that trigger IFRS 1 application include:

Local GAAP to IFRS

An entity previously reporting under national standards (e.g., US GAAP, UK GAAP, Indian AS) that now adopts IFRS as its reporting framework.

Initial Public Offering

A company listing on a stock exchange that requires IFRS-compliant financial statements for the first time, having previously reported only for internal purposes.

Regulatory Mandate

A jurisdiction legislates the adoption of IFRS for public interest entities, requiring all qualifying companies to transition by a specified date.

Re-adoption of IFRS

An entity that previously used IFRS, then switched to local GAAP, and now returns to IFRS; IFRS 1 applies again unless an exemption exists.

Key Definition: First IFRS Financial Statements

The entity’s first IFRS financial statements are the first annual financial statements in which the entity adopts IFRS by an explicit and unreserved statement of compliance with IFRS in accordance with IAS 1 Presentation of Financial Statements.

The Process

Transition Steps Under IFRS 1

IFRS 1 establishes a structured pathway to ensure the opening IFRS balance sheet provides a high-quality, reliable foundation. The following key steps guide the transition:

01

Identify the Transition Date

The transition date is the beginning of the earliest period for which the entity presents full comparative IFRS information, generally the start of the prior year.

02

Prepare the Opening Balance Sheet

At the transition date, prepare a statement of financial position that complies with IFRS in force at the end of the first IFRS reporting period.

03

Recognize Required Assets & Liabilities

Recognize all assets and liabilities required by IFRS. Derecognize items not permitted under IFRS. Reclassify items as required by IFRS.

04

Apply Measurement Requirements

Measure all recognised assets and liabilities applying IFRS retrospectively, unless an optional exemption or mandatory exception applies.

05

Apply Exemptions & Exceptions

Elect any applicable optional exemptions to reduce the cost of transition, and comply with all five mandatory exceptions.

06

Disclose & Reconcile

Provide comparative information and detailed reconciliations explaining the effect of the transition from previous GAAP to IFRS.

“The objective of IFRS 1 is to ensure that an entity’s first IFRS financial statements, and its interim financial reports for part of the period covered by those financial statements, contain high-quality information that is transparent for users.”

Key Dates in the IFRS 1 Timeline

T − 2 years (minimum)

Transition Date

The beginning of the earliest comparative period presented in the entity’s first IFRS financial statements. All IFRS principles are applied from this date onwards.

T − 1 year

Start of Comparative Period

The beginning of the period that will be presented as comparative information in the first IFRS report. Accounting policies must be consistent with IFRS throughout.

T

End of First IFRS Reporting Period

The date of the first complete set of IFRS financial statements, including balance sheet, income statement, other comprehensive income, cash flows, notes, and the IFRS 1 disclosures.

Cost Relief Provisions

Optional Exemptions

IFRS 1 provides a range of optional exemptions from full retrospective application. These are voluntary, an entity chooses whether to apply each exemption based on its circumstances. They exist because full retrospective application may be impractical or cost-prohibitive in certain areas.

Business Combinations

An entity need not restate business combinations that occurred before the transition date under IFRS 3. A prospective approach is permitted.

Property, Plant & Equipment

Fair value or a revaluation may be used as deemed cost for PP&E at the transition date, avoiding costly retrospective depreciation calculations.

Employee Benefits

Cumulative actuarial gains and losses may be recognized in full at the transition date without restating the corridor method retrospectively.

Cumulative Translation Differences

Cumulative translation differences for all foreign operations may be deemed zero at the transition date, simplifying currency conversion history.

Compound Financial Instruments

If the liability component of a compound instrument has been extinguished at transition, there is no need to split equity and liability retrospectively.

Share-Based Payments

An entity is not required to apply IFRS 2 to equity instruments granted on or before certain dates, reducing the retrospective measurement burden.

Leases

Entities may rely on previous GAAP assessments of lease classification rather than reassessing from inception under IFRS 16, subject to conditions.

Insurance Contracts

First-time adopters may apply transitional provisions of IFRS 17 rather than full retrospective application, easing the complexity of restating long-tail contracts.

Non-Negotiable Rules

Mandatory Exceptions

Unlike optional exemptions, mandatory exceptions prohibit retrospective application. A first-time adopter must not apply IFRS retrospectively in these five areas, the IASB concluded that the costs and subjectivity risks of doing so would undermine the reliability of financial information.

Estimates

Estimates at the transition date must be consistent with estimates made under previous GAAP (after adjustments for GAAP differences), unless there is objective evidence of error. Hindsight is not permitted.

Derecognition of Financial Instruments

Financial assets and liabilities derecognised before the transition date under previous GAAP are not reinstated. The derecognition is accepted as a fait accompli.

Hedge Accounting

Only hedging relationships that meet IFRS 9’s qualifying criteria as of the transition date may be reflected in hedge accounting. Prior hedges not qualifying must be unwound.

Non-Controlling Interests

Certain IFRS 10 requirements regarding non-controlling interests are applied prospectively from the transition date only, not retrospectively.

Classification & Measurement of Financial Assets

The classification of financial assets is based on facts and circumstances existing at the transition date rather than at the original recognition date.

Transparency Requirements

Disclosure Requirements

The disclosure requirements under IFRS 1 are extensive. Their purpose is to help users understand the financial impact of the transition and to assess how the opening IFRS numbers differ from what was reported under previous GAAP. Key disclosures include:

  • Equity reconciliation: A reconciliation of equity reported under previous GAAP to IFRS equity, for both the transition date and the end of the latest period presented in the most recent previous GAAP financial statements.
  • Total comprehensive income reconciliation: A reconciliation of the total comprehensive income reported under previous GAAP to IFRS, for the comparative period.
  • Explanatory notes: Sufficient explanation of material adjustments to the balance sheet, income statement, and cash flows to enable users to understand the transition effects.
  • Errors corrected: Disclosure of any errors identified in previous GAAP financial statements that are corrected as part of the IFRS transition.
  • Fair value as deemed cost: Where an entity has used fair value as deemed cost for any asset or liability, disclosure of the aggregate of those fair values and the aggregate adjustment.
  • Optional exemptions elected: Disclosure of which optional exemptions the entity has elected to apply, enabling users to compare across first-time adopters.
  • Interim reports: If an entity presents IFRS interim reports in the year of transition, additional reconciliation disclosures are required under IFRS 1.32–33.
“The reconciliations required by IFRS 1 are among the most insightful disclosures in any financial report, they lay bare the full effect of accounting policy differences on reported wealth and performance.”
Key Differences

IFRS 1 vs. Transitioning from US GAAP

While IFRS and US GAAP have converged on many issues, significant differences remain. Entities transitioning from US GAAP to IFRS commonly encounter adjustments in the following areas:

Common Questions

Frequently Asked Questions

What is IFRS 1 and why does it exist?
IFRS 1 exists because transitioning to a new set of accounting standards is complex and potentially costly. Without a dedicated standard, entities would face inconsistent approaches to the transition i.e. undermining comparability. IFRS 1 provides a structured, cost-effective pathway that ensures the opening IFRS balance sheet is transparent and reliable, while allowing practical exemptions where full retrospection would be unnecessarily burdensome.
What is the “deemed cost” concept in IFRS 1?
Deemed cost is an amount used as a surrogate for the cost (or depreciated cost) that would otherwise be determined under IFRSs. IFRS 1 allows an entity to use fair value at the transition date as the deemed cost of items like PP&E, investment property, and intangibles. This avoids the need to reconstruct historical cost and depreciation records going back decades, which may be impractical or unavailable.
Does IFRS 1 apply to interim financial reports?
Yes. If an entity presents an interim financial report under IAS 34 for part of the period covered by its first IFRS financial statements, IFRS 1 requirements apply. The interim report must include reconciliations showing the impact of the transition on equity and profit or loss for the comparable interim period, enabling investors to track the effect of IFRS adoption throughout the year.
Can an entity choose not to restate comparative periods?
No. IFRS 1 requires at least one year of IFRS comparative information. The general rule is full retrospective application from the transition date. The optional exemptions reduce the scope of retrospective restatement in specific areas, but they do not allow an entity to entirely avoid presenting comparative IFRS information. The comparative period must be presented under IFRS alongside the full reconciliation disclosures.
How does IFRS 1 affect goodwill from past acquisitions?
Under the IFRS 1 business combinations exemption, goodwill from pre-transition acquisitions is generally taken at its previous GAAP carrying amount at the transition date (with adjustments for differences between IFRS and previous GAAP). Crucially, goodwill is no longer amortised under IFRS as it is subject to annual impairment testing under IAS 36. Any amortisation charged under previous GAAP since the acquisition is not reversed, but prospective amortisation ceases.
What happens to deferred taxes at transition?
Deferred taxes under IAS 12 must be recognised on all temporary differences arising from the transition adjustments. IFRS 1 does not provide exemptions in this area; entities must recognise all deferred tax assets and liabilities that IFRS requires, including those arising from fair value adjustments, IFRS 16 lease capitalisation, and other transition adjustments. The deferred tax impact is taken through retained earnings in the opening IFRS balance sheet.
