Key Takeaways
- The IASB replaced the IASC in 2001 and assumed responsibility for all existing IAS standards.
- IFRS Standards are required or permitted in over 140 jurisdictions, covering the majority of listed companies outside the United States.
- Auditors must track active IASB projects because a new or amended standard can change recognition, measurement, or disclosure requirements mid-engagement.
- The IASB's due process requires an exposure draft with a minimum 120-day comment period before any standard is finalised.
What is IASB (International Accounting Standards Board)?
The IASB sits within the IFRS Foundation, a not-for-profit organisation governed by a board of trustees. The IASB itself comprises 14 members appointed for renewable five-year terms, with geographic diversity requirements written into the Foundation Constitution (paragraphs 26–27). Each new or revised standard passes through a structured due process: research, discussion paper (optional), exposure draft, re-deliberation, and final issuance. The IFRS Interpretations Committee handles narrower application questions and refers broader issues back to the Board.
For practitioners, the IASB's output determines the accounting framework applied on most European statutory audits. When the IASB issues a new standard (as it did with IFRS 18 replacing IAS 1 for presentation of financial statements), auditors must assess whether clients have adopted the standard correctly and whether transitional provisions create measurement differences between reporting periods. The EU endorsement mechanism adds a layer: a standard issued by the IASB does not apply in the EU until the European Commission endorses it through the European Financial Reporting Advisory Group (EFRAG) process. This creates a timing gap that auditors need to track on every IFRS engagement.
Worked example: Rossi Alimentari S.p.A.
Client: Italian food production company, FY2025, revenue EUR 67M, IFRS reporter. The audit team must evaluate whether Rossi has correctly applied a newly effective IASB standard during the current reporting period.
Step 1 — Identify newly effective IASB standards
The engagement team reviews the IASB's effective date schedule for FY2025. Two amendments apply: amendments to IAS 21 (Lack of Exchangeability, effective 1 January 2025) and amendments to IAS 7 and IFRS 7 (Supplier Finance Arrangements, effective 1 January 2024 with first-year transition reliefs expiring in 2025). The team confirms EU endorsement status for both.
Step 2 — Assess IAS 21 amendment impact
Rossi sources raw materials from a subsidiary in Argentina. The Argentine peso has been subject to exchange restrictions. Under the IAS 21 amendment, Rossi must assess whether the peso is exchangeable at the measurement date and, if not, estimate the spot rate using an observable rate that reflects economic conditions. Rossi applies the official central bank rate adjusted for the parallel market premium, arriving at an estimated spot rate of ARS 1,420 per EUR compared to the official rate of ARS 1,180 per EUR. The difference produces a EUR 740,000 foreign currency translation adjustment on the subsidiary's net assets of approximately EUR 4.1M.
Step 3 — Evaluate supplier finance arrangement disclosures
Rossi participates in a reverse factoring programme with Banca Intesa covering EUR 8.2M in trade payables. The IFRS 7 amendments require disclosure of the carrying amount of financial liabilities in the programme, the line items in which those liabilities are presented, the range of payment due dates, and the type of supplier finance arrangement. Rossi has included these disclosures in Note 22 to the financial statements.
Conclusion: the audit file demonstrates that Rossi identified both IASB amendments and applied the IAS 21 exchangeability test with a documented estimation methodology. The supplier finance disclosures satisfy the IFRS 7 requirements. The approach is defensible because each step traces to the specific IASB paragraphs that took effect during FY2025.
Why it matters in practice
Teams at smaller firms often fail to perform a systematic new-standards assessment at the planning stage. ISA 315.13 requires the auditor to understand the applicable financial reporting framework. When a newly effective IASB standard changes recognition or measurement requirements (even through narrow-scope amendments), the risk assessment must reflect that change. Treating the framework as static from year to year is the gap.
Practitioners sometimes apply an IASB standard before it has received EU endorsement, or conversely fail to apply an endorsed standard because they reference the IASB effective date rather than the EU-endorsed effective date. The two dates can differ by six to eighteen months. IAS 8.30 governs early adoption, but early adoption of a non-endorsed standard is not permitted under EU-adopted IFRS.
IASB vs. FASB
| Dimension | IASB | FASB |
|---|---|---|
| Standards issued | IFRS and IAS | US GAAP (ASC Topics) |
| Jurisdiction | Over 140 countries; mandatory in the EU, UK, Australia, and others | United States (SEC registrants and entities following US GAAP) |
| Governance body | IFRS Foundation | Financial Accounting Foundation (FAF) |
| Due process timeline | Exposure draft with 120-day minimum comment period | Proposed ASU with 60- to 90-day comment period (extensible) |
| Principles vs. rules orientation | Principles-based with limited bright-line thresholds | Rules-based with specific quantitative criteria in many areas |
The distinction matters most on cross-border engagements. When a European IFRS reporter has a US-listed parent, the auditor must reconcile measurement differences between the two frameworks. The IASB and FASB ran a formal convergence programme from 2002 to 2014, narrowing gaps on revenue (IFRS 15 and ASC 606 are near-identical) and leases (IFRS 16 and ASC 842 diverge on lessee classification). Knowing which areas converged and which did not prevents misplaced reliance on one framework when auditing under the other.

Frequently asked questions
What is the difference between IAS and IFRS standards?
IAS standards were issued by the IASC (the IASB's predecessor body) before 2001. IFRS standards are issued by the IASB from 2003 onward. Both carry equal authority under the IFRS Foundation Constitution. The numbering simply reflects the issuing body. IAS standards remain in force until the IASB replaces them (as IFRS 18 replaces IAS 1, effective from 2027).
How does the IASB's due process affect my audit timeline?
A new IASB standard typically takes two to five years from project inception to final issuance. Once issued, the effective date is usually 12 to 18 months away. ISA 570.A2 and ISA 315.A60 expect auditors to consider the effect of standards issued but not yet effective on the going concern and risk assessments. Monitor the IASB work plan quarterly to avoid surprises at year-end.
Does the IASB have enforcement powers?
No. The IASB sets standards but has no authority to enforce them. Enforcement sits with national regulators and securities authorities. In the EU, the European Securities and Markets Authority (ESMA) coordinates enforcement of IFRS application across member states. In the Netherlands, the AFM inspects compliance as part of its statutory audit oversight under the Wta.
