Conceptual and Regulatory Framework (Advanced)

Advanced study of the conceptual framework underpinning corporate reporting and the regulatory environment governing financial reporting. The IASB standard-setting process: IFRS Foundation governance (Trustees, Monitoring Board), IASB and IFRS Interpretations Committee composition and roles, due process for standard-setting (research, exposure draft, comment period, redeliberations, final standard, post-implementation review), International Sustainability Standards Board (ISSB) sister-board for sustainability standards. IFRS vs UK GAAP comparison: FRS 102 (the main UK standard for medium and small entities) — key differences from IFRS in revenue recognition, leases (not adopted IFRS 16 yet), financial instruments (simpler classification), goodwill amortisation (mandatory vs impairment-only), retirement benefits, deferred tax. UK regulatory environment: Financial Reporting Council (FRC) - role as standard-setter, monitor of audit quality, professional oversight; Financial Conduct Authority (FCA) — Listing Rules and Disclosure Guidance and Transparency Rules; Prudential Regulation Authority (PRA); proposed Audit Reporting and Governance Authority (ARGA) reform. Current issues in financial reporting: post-implementation reviews (IFRS 9, 15, 16), changes to IAS 1 (Presentation of Financial Statements — revisions on liabilities), IAS 12 (deferred tax on assets and liabilities arising from a single transaction), IAS 8 (definition of accounting estimates). Sustainability reporting: ISSB IFRS S1 (general requirements for sustainability-related disclosures) and IFRS S2 (climate-related disclosures), TCFD recommendations, EU CSRD, UK Sustainability Disclosure Requirements (SDR). Integrated reporting (<IR>) framework. Alternative Performance Measures (APMs) — ESMA guidelines, FRC concerns over use of non-GAAP measures.

IASB and the Standard-Setting Process

The IFRS Foundation is the not-for-profit international body responsible for issuing IFRS standards globally. Its governance structure ensures international standard-setting is carried out with public oversight, technical expertise, and due process.

IFRS Foundation governance structure:

BodyRole
Monitoring Board Public-interest oversight. Includes IOSCO, FCA, US SEC. Oversees the Trustees.
Trustees Govern the Foundation; appoint IASB and ISSB members; secure funding; oversee due process. ~22 trustees from diverse geographies.
IASB (International Accounting Standards Board) Issue IFRS Accounting Standards. ~14 members, full-time, technical experts. Set agenda for standard-setting.
ISSB (International Sustainability Standards Board) Issue IFRS Sustainability Disclosure Standards. Sister body to IASB; established 2021.
IFRS Interpretations Committee (IFRIC) Interpret IFRS standards; address application questions. Issues IFRIC interpretations.
IFRS Advisory Council Strategic advice; broad stakeholder input

The IASB due process for new standards:

  1. Research / agenda decision: identify potential project; staff papers; consultation
  2. Discussion paper (optional): preliminary views; broad public consultation
  3. Exposure Draft (ED): detailed proposals; minimum 90-day public comment period
  4. Redeliberations: IASB considers comments; may issue revised ED
  5. Final standard: published with Basis for Conclusions explaining decisions
  6. Post-implementation review (PIR): typically 2-3 years after effective date; assess whether standard is achieving objectives

Key principles of due process:

  • TRANSPARENCY: meetings webcast; papers published
  • FULL CONSULTATION: minimum comment periods; outreach in different jurisdictions
  • ACCOUNTABILITY: Trustees oversee; Monitoring Board provides public oversight
  • EVIDENCE-BASED: research, field tests, cost-benefit analysis
  • VOTING: 8 of 14 IASB members must approve a final standard

Recent IASB developments:

  • IFRS 17 Insurance Contracts effective 2023 (replacing IFRS 4)
  • IFRS 18 Presentation and Disclosure in Financial Statements (effective 2027 — replacing IAS 1)
  • IFRS 19 Subsidiaries Without Public Accountability (reduced disclosures option)
  • Multiple amendments to IAS 1, IAS 12, IAS 8, IFRS 16
  • Sustainability standards via ISSB

UK adoption process:

  • UK adopted IFRS for listed companies' consolidated accounts since 2005
  • Post-Brexit (1 Jan 2021): UK has its own endorsement process via UK Endorsement Board (UKEB)
  • UKEB reviews each new IFRS for UK applicability before mandatory adoption
  • Generally has aligned with IASB but can deviate
  • FRC oversees UKEB

IFRS vs UK GAAP (FRS 102)

UK financial reporting framework:

StandardApplied to
IFRS (UK-endorsed) Listed companies' consolidated accounts (mandatory); other entities by choice
FRS 100 Application of Financial Reporting Requirements — sets out which framework applies
FRS 101 Reduced Disclosure Framework — qualifying entities (subsidiaries) using IFRS recognition/measurement with reduced disclosures
FRS 102 Main UK GAAP standard for medium-sized and small entities. Significantly simpler than full IFRS.
FRS 105 Micro-entities — even simpler regime

Key differences — IFRS vs FRS 102:

1. Revenue Recognition:

  • IFRS 15: detailed 5-step model
  • FRS 102: simpler approach, but FRS 102 was AMENDED in 2024 to ALIGN with IFRS 15 (effective from accounting periods beginning 1 January 2026)

2. Leases:

  • IFRS 16: ALL leases on balance sheet (right-of-use asset + lease liability)
  • FRS 102: lessees split between operating and finance leases (operating off-balance-sheet) — DIFFERENT from IFRS 16
  • FRS 102 amended in 2024 — converging WITH IFRS 16 but with simplifications. Effective 2026.

3. Financial Instruments:

  • IFRS 9: complex classification (amortised cost, FVOCI, FVTPL); business model + SPPI tests; expected credit losses
  • FRS 102: simpler classifications; basic incurred loss model historically (now moving towards expected credit losses)

4. Goodwill:

  • IFRS 3: NO AMORTISATION; impairment testing only (annual)
  • FRS 102: SYSTEMATIC AMORTISATION over useful life (default 10 years if not reliably estimable)
  • Significant difference — IFRS may have higher goodwill on the balance sheet for longer

5. Investment Property:

  • IAS 40: choice of cost or fair value model
  • FRS 102: fair value model REQUIRED (where reliably measurable)

6. Retirement Benefits (Defined Benefit):

  • IAS 19: complex measurement; remeasurements through OCI
  • FRS 102: similar approach for medium-sized entities; some simplifications for small entities (group defined contribution treatment for participating in group plan)

7. Deferred Tax:

  • IAS 12: temporary differences approach (full provision)
  • FRS 102: timing differences approach + some "timing differences plus" — historically less aggressive than IAS 12
  • Recent FRS 102 amendments aligning closer to IAS 12

8. Investment in Associates / JVs:

  • IAS 28 / IFRS 11: equity method standard
  • FRS 102: equity method or cost model permitted in individual entity accounts

Why use FRS 102 vs IFRS?

  • FRS 102: simpler, less burden, less disclosure
  • IFRS: required for listed; useful for international comparisons
  • FRS 102 still produces "true and fair" view; not inferior — just different
  • Most UK private companies use FRS 102; smaller entities use FRS 105

FRS 102 periodic review (2024):

  • FRC conducted comprehensive review
  • Major changes: revenue recognition aligned with IFRS 15; lease accounting aligned with IFRS 16 (with simplifications)
  • Effective for accounting periods beginning on or after 1 January 2026
  • Significant transition for FRS 102 reporters

UK Regulatory Environment

UK financial reporting is overseen by multiple regulators with overlapping but distinct roles.

Financial Reporting Council (FRC):

  • Independent regulator for accounting, auditing, and corporate governance
  • Sets UK accounting standards (FRS 100-105)
  • Oversees UK Endorsement Board (UKEB) for IFRS adoption
  • Monitors quality of audit firms and audits (audit firm inspections)
  • Sets the UK Corporate Governance Code (for listed companies) and UK Stewardship Code
  • Enforces accounting standards via Audit and Actuarial Discipline (AAD) and Corporate Reporting Review
  • Investigates failures (e.g., Carillion, BHS, Patisserie Valerie)

FRC enforcement powers:

  • Reviews of corporate accounts: identification of poor reporting
  • "Direction" to amend accounts (under s.456 Companies Act 2006)
  • Penalties on auditors for poor work
  • Disciplinary actions against accountants/auditors

Audit Reform — Towards ARGA:

  • Following Carillion, BHS, Patisserie Valerie scandals: government-commissioned reports (Brydon, Kingman, CMA)
  • Proposed: Audit, Reporting and Governance Authority (ARGA) to replace FRC
  • Stronger powers: direct intervention; statutory force; enhanced auditor regulation
  • Implementation timeline: legislation expected but delayed; specific date uncertain
  • Goal: restore public confidence in audit and corporate reporting

Financial Conduct Authority (FCA):

  • Conducts business regulator for UK financial services
  • Listing Authority for the UK's primary listing markets
  • Listing Rules: requirements for premium listing (most demanding) and standard listing
  • Disclosure Guidance and Transparency Rules (DTRs): periodic financial reporting; market disclosures
  • Listing Rules require IFRS adoption for premium listed
  • Sanctions: censures, fines, restrictions on activities

Listing Rules — key reporting requirements:

  • Annual report and accounts (PUBLISHED within 4 months of year-end)
  • Half-yearly financial report (within 3 months of half-year end)
  • Audited consolidated financial statements (IFRS)
  • Compliance statement on UK Corporate Governance Code (premium listing)
  • Sustainability disclosures (TCFD; planning for ISSB)
  • Disclosure of related party transactions

Prudential Regulation Authority (PRA):

  • Part of the Bank of England
  • Prudential supervision of banks, building societies, insurers, major investment firms
  • Sets capital and liquidity requirements (BASEL III implementation)
  • Reporting requirements: detailed regulatory returns
  • Reviews accounting policies for prudential implications (e.g., expected credit losses on loans)

Companies House:

  • Registers UK companies; receives filed accounts
  • Public access to filings
  • Penalties for late filing
  • Companies House reform (2024): improvements to data accuracy, beneficial ownership registers

HMRC:

  • Tax authority — interest in financial reporting for CT purposes
  • Some accounting policies have direct tax implications (e.g., revenue recognition; lease accounting)
  • HMRC may request specific accounting treatments for tax purposes

International coordination:

  • UK active in IOSCO (International Organization of Securities Commissions)
  • International Forum of Independent Audit Regulators (IFIAR)
  • Post-Brexit: UK retains close cooperation with EU regulators

Sustainability Reporting and ISSB Standards

Sustainability reporting has become a major frontier in corporate reporting. The IFRS Foundation established the ISSB in November 2021 to develop GLOBAL sustainability reporting standards.

International Sustainability Standards Board (ISSB):

  • Sister board to IASB under IFRS Foundation
  • Develops IFRS Sustainability Disclosure Standards
  • Building on TCFD (Task Force on Climate-related Financial Disclosures), CDSB, VRF, IIRC
  • Aims for global consistency in sustainability reporting

IFRS S1 — General Requirements for Disclosure of Sustainability-Related Financial Information:

  • Effective for annual reporting periods beginning 1 January 2024
  • Establishes the FOUNDATION for sustainability disclosures
  • Four pillars (aligned with TCFD):
    • Governance: oversight of sustainability risks/opportunities
    • Strategy: how sustainability matters affect business
    • Risk management: identification, assessment, management of risks
    • Metrics and targets: data to evaluate performance
  • Materiality: investor-focused (financial materiality — what affects enterprise value)
  • Reporting boundary: same as the financial statements
  • Connectivity: sustainability info connected to financial statements

IFRS S2 — Climate-Related Disclosures:

  • Effective same date as S1 (1 January 2024)
  • SPECIFIC requirements for climate-related disclosures
  • Builds on TCFD:
    • Physical risks (acute weather events; chronic temperature changes)
    • Transition risks (regulatory; technology; market; reputation)
    • Climate-related opportunities
  • Required disclosures:
    • Greenhouse gas emissions (Scope 1, 2, 3 — reporting all three)
    • Climate scenario analysis
    • Transition plans
    • Industry-specific metrics (drawing on SASB standards)
    • Capital deployment and management of climate-related risks

UK adoption:

  • UK Sustainability Disclosure Standards (UK SDS) being developed
  • Expected to broadly endorse IFRS S1 and S2 for UK companies
  • UK Sustainability Disclosure Requirements (SDR) being implemented for retail investors and asset managers (FCA)
  • UK Streamlined Energy and Carbon Reporting (SECR): mandatory for large companies (since 2019)

EU comparison:

  • EU CSRD (Corporate Sustainability Reporting Directive): mandatory for large EU companies and EU subsidiaries of non-EU groups
  • EU ESRS (European Sustainability Reporting Standards): more comprehensive than ISSB; double materiality (financial + impact materiality)
  • UK has chosen the more focused investor-led ISSB approach
  • Multinationals may need to comply with both regimes

Other major sustainability frameworks:

FrameworkFocusStatus
TCFD Climate financial disclosures Foundation for IFRS S2; widely adopted
GRI (Global Reporting Initiative) Broad sustainability impacts Most-used global standard for sustainability
SASB Industry-specific financial materiality Now part of ISSB; embedded in S1/S2
CDSB Climate disclosure Consolidated into ISSB
VRF (Value Reporting Foundation) Integrated reporting + SASB Consolidated into ISSB

Integrated reporting (<IR>):

  • Holistic single report covering both financial and sustainability matters
  • Six "capitals": financial, manufactured, intellectual, human, social/relationship, natural
  • Tells the "value creation story"
  • Now part of the ISSB framework
  • Voluntary in most jurisdictions

Current Issues and Recent Changes

Corporate reporting is a constantly evolving area. Recent developments and ongoing issues:

Recent IFRS amendments (2022-2024):

1. IAS 1 amendments — Classification of Liabilities (2020, effective 2024):

  • Clarifies when liabilities are classified as current or non-current
  • Based on rights existing AT END of reporting period (not subsequent events)
  • Conditions met after period end: assess as if existed at year-end
  • Only "substantive" rights count

2. IAS 1 amendments — Disclosure of Accounting Policies (2021, effective 2023):

  • Requires disclosure of MATERIAL accounting policies (not "significant")
  • Less repetition of standard policies
  • More entity-specific and useful disclosures

3. IAS 8 amendments — Definition of Accounting Estimates (2021, effective 2023):

  • Clearer distinction between accounting policies (changed retrospectively) and estimates (changed prospectively)
  • Helps consistency in applying changes

4. IAS 12 amendments — Deferred Tax on Single Transactions (2021, effective 2023):

  • Clarifies deferred tax accounting on transactions giving rise to BOTH a deferred tax asset and a deferred tax liability (e.g., leases — IFRS 16 right-of-use asset and lease liability)
  • Recognise both DTA and DTL even though net effect may be small

5. IAS 12 amendments — Pillar Two (2023):

  • Temporary mandatory exception from recognising deferred tax assets/liabilities for Pillar Two top-up taxes
  • Practical relief due to complexity of computing deferred tax for global minimum tax

6. IFRS 18 — Presentation and Disclosure (effective 2027):

  • Replaces IAS 1 entirely
  • New SOPL structure with categories (operating, investing, financing)
  • Subtotals for "Operating profit" and "Profit before financing and tax"
  • Management-defined performance measures (MPMs) — required disclosure of how derived
  • Aimed at improving comparability

Post-implementation reviews:

  • IFRS 9 (Financial Instruments): PIR completed 2022; refining classification, ECL model
  • IFRS 15 (Revenue): PIR completed 2024; mostly working well; clarifying license accounting
  • IFRS 16 (Leases): PIR underway 2024-2026

Cryptocurrency and digital assets:

  • No specific IFRS standard yet — applies existing standards by analogy
  • IAS 38 (Intangible) most commonly applied — but limitations
  • Inventory if held for trading; financial asset if cash-like
  • FASB (US) recently updated to fair value for crypto held by non-traders
  • IFRS likely to follow with specific guidance

Rate-regulated activities:

  • Long-running IASB project
  • Regulated industries (utilities) have unique business model
  • "Regulatory deferral accounts" recognise impact of rate regulation
  • IFRS 14 currently allows existing GAAP for first-time adopters; permanent solution being developed

Management commentary / strategic report:

  • UK strategic report (Companies Act 2006 s.414C): narrative including business model, KPIs, risks
  • IASB Practice Statement 1 on Management Commentary (revised draft)
  • FRC has issued guidance on strategic report content
  • Increasing focus on non-financial information and sustainability

Digital reporting (XBRL):

  • Inline XBRL (iXBRL) mandatory for UK Companies House since 2011 for most entities
  • FCA requires structured European Single Electronic Format (ESEF) for listed companies' annual reports
  • Tagging requirements increasingly detailed

Alternative Performance Measures (APMs)

Alternative Performance Measures (APMs) are non-GAAP measures used by companies to provide additional information about performance. Common examples: EBITDA, "underlying profit", "adjusted earnings", "constant currency", "like-for-like".

Why companies use APMs:

  • Show "core" or "underlying" performance excluding "one-off" items
  • Compare performance year-on-year on a consistent basis
  • Strip out non-cash items (depreciation, amortisation) for cash-generation analysis
  • Industry-specific measures (e.g., RevPAR for hotels, like-for-like sales for retail)
  • Highlight metrics they want investors to focus on

Concerns and abuses:

  • "Cherry picking" what to exclude — often excluding bad news, including good
  • "Underlying profit" often consistently higher than statutory profit
  • Inconsistency over time (definition changes)
  • Difficulty comparing across companies (different definitions)
  • Excluding "non-recurring" items that recur every year
  • Promoting non-GAAP over GAAP measures

ESMA / FCA / FRC Guidelines on APMs:

  • ESMA Guidelines on APMs (2015) — applied by FCA in UK
  • Apply to companies with publicly traded securities
  • Supplemented by FRC guidance

Key requirements:

  1. Define: explain how the APM is calculated
  2. Reconcile: to nearest GAAP measure
  3. Explain why used: relevance to investors
  4. Consistency: same definition each period (changes explained)
  5. NOT MORE PROMINENT than GAAP measures: GAAP must come first
  6. Comparatives: at least one year of comparative APM
  7. Identify items excluded: explain what makes them "exceptional" or "underlying"

Common APMs and considerations:

APMCommon useConcerns
EBITDA Cash-generation proxy; debt capacity Ignores capital intensity; non-comparable definitions
Underlying profit / "adjusted EBITDA" "Recurring" performance What is/isn't included? Often manipulated
Like-for-like sales Same-store growth (retail) Definition of "like-for-like" varies
Free cash flow Discretionary cash generation Capex definitions vary; some exclude lease payments
Constant currency Underlying revenue trend Selective exchange rate basis

FRC concerns:

  • Annual review reports highlight common APM weaknesses
  • Frequent issues:
    • "One-off" items recurring year after year
    • Reconciliation not clear or complete
    • APM more prominent than GAAP figures
    • Inconsistent application across periods
    • Misleading labelling
  • FRC reviews can require amendments

IFRS 18 impact (effective 2027):

  • Introduces concept of "Management-defined Performance Measures" (MPMs)
  • Required to disclose IF an MPM is used in PUBLIC communications
  • Reconciliation, definition, why used
  • Brings APMs into the audited financial statements (rather than just narrative report)
  • Should improve transparency and discipline around APMs

Best practice for APMs:

  • Define clearly and consistently
  • Reconcile fully to GAAP
  • Apply consistently each period
  • Explain rationale
  • Don't make them more prominent than GAAP
  • Apply judgement honestly — don't systematically exclude bad news
  • Audit committee review

Examiner Focus

CR exam questions on the framework typically test (1) understanding of WHO sets standards and HOW; (2) differences between IFRS and FRS 102 (particularly post-2026 reform); (3) regulatory environment; (4) sustainability reporting (rapidly evolving area). Be prepared to discuss CURRENT issues — examiners want awareness of recent developments, not just historical understanding.

Common Pitfall

IFRS vs FRS 102 differences are nuanced. The big differences (lease accounting, goodwill amortisation, revenue recognition) are CHANGING with FRS 102 reform effective 2026. For exam purposes, know both: pre-2026 differences AND the post-2026 alignment. Understand WHICH standards remain different (e.g., FRS 102 will still mandate goodwill amortisation; IFRS will continue impairment-only).

Study Tip

Standard-setting due process is examinable: Research → Discussion paper (optional) → Exposure draft (90-day comment) → Redeliberations → Final standard → Post-implementation review. Understand the role of each step. Voting threshold: 8 of 14 IASB members must approve standards.

Examiner Focus

Sustainability reporting (ISSB, IFRS S1 and S2) is a new and growing topic. Effective from accounting periods beginning 1 January 2024. Four-pillar TCFD-aligned structure: governance, strategy, risk management, metrics and targets. UK developing UK SDS based on ISSB. EU CSRD different (double materiality). These differences are exam-worthy.

Watch Out

APM regulation: must be defined, reconciled to nearest GAAP measure, explained, consistent year-on-year, NOT more prominent than GAAP figures. Common abuses: "one-off" items recurring; cherry-picking exclusions; inconsistent definitions. ESMA/FCA/FRC enforcement. IFRS 18 (2027) will introduce "Management-defined Performance Measures" with disclosure requirements bringing APMs into audited statements.

Study Tip

UK regulators can be confused. FRC = independent standard-setter and audit/governance regulator (proposed to be replaced by ARGA). FCA = listing authority + listed company disclosures. PRA = prudential regulation of banks/insurers (Bank of England). UKEB = post-Brexit IFRS endorsement. These are distinct roles — questions often test understanding of WHICH regulator does WHAT.

Study Tip

Recent IFRS amendments are exam-relevant. IAS 1 amendments (current/non-current liabilities; material accounting policies); IAS 8 (definition of accounting estimates); IAS 12 (deferred tax on transactions giving rise to both DTA/DTL — leases; Pillar Two relief). These technical updates are often tested.

Key Definitions

IFRS Foundation

International, not-for-profit body issuing IFRS standards. Governance: Monitoring Board (public oversight), Trustees (governance), IASB (accounting standards), ISSB (sustainability standards), IFRIC (interpretations).

IASB due process

Standard-setting steps: research / agenda decision → discussion paper (optional) → exposure draft (90+ day comment) → redeliberations → final standard → post-implementation review (2-3 years after effective date). 8 of 14 IASB members must approve standards.

UK Endorsement Board (UKEB)

Post-Brexit body established 2021. Reviews each new IFRS for UK applicability before mandatory adoption. Generally aligned with IASB. Overseen by FRC.

FRS 102

Main UK GAAP standard for medium and small entities. Differs from IFRS in: revenue (simpler — being aligned to IFRS 15 from 2026); leases (operating leases off-BS — being aligned to IFRS 16 from 2026); financial instruments (simpler); goodwill (mandatory amortisation, default 10 years); investment property (fair value required).

FRC (Financial Reporting Council)

UK independent regulator for accounting, auditing, governance. Sets UK accounting standards. Oversees UKEB. Monitors audit quality. Sets UK Corporate Governance Code. Investigates failures (Carillion, Patisserie Valerie, BHS). Being replaced by ARGA (proposed).

ARGA (proposed)

Audit, Reporting and Governance Authority — proposed replacement for FRC. Stronger powers, statutory force, enhanced auditor regulation. Following Carillion etc. Implementation timeline uncertain — legislation pending.

FCA Listing Rules

UK premium and standard listing requirements. IFRS for premium listed; annual report within 4 months; half-yearly within 3 months; UK Corporate Governance Code compliance statement; sustainability disclosures.

ISSB (International Sustainability Standards Board)

IFRS Foundation's sister board (established 2021) for sustainability standards. Issues IFRS Sustainability Disclosure Standards (S1, S2 effective 1 January 2024). Builds on TCFD, CDSB, VRF, IIRC.

IFRS S1

General Requirements for Disclosure of Sustainability-Related Financial Information. Four-pillar structure (governance, strategy, risk management, metrics and targets). Investor-focused (financial materiality). Effective 1 January 2024.

IFRS S2

Climate-Related Disclosures. Builds on TCFD. Required: Scope 1, 2, 3 emissions; climate scenario analysis; transition plans; industry-specific metrics. Aligns with SASB standards. Effective 1 January 2024.

TCFD

Task Force on Climate-related Financial Disclosures. Foundational framework adopted globally for climate disclosures. Four pillars: governance, strategy, risk management, metrics and targets. Now embedded in IFRS S2.

EU CSRD vs ISSB

EU's Corporate Sustainability Reporting Directive (mandatory for large EU companies + EU subsidiaries of non-EU groups) uses ESRS — comprehensive with DOUBLE MATERIALITY (financial + impact). ISSB more focused: investor-led financial materiality only. Multinationals may need to comply with both.

Integrated reporting (<IR>)

Holistic single report covering financial and sustainability. Six capitals: financial, manufactured, intellectual, human, social/relationship, natural. Tells "value creation story". Now part of ISSB framework. Voluntary in most jurisdictions.

APM (Alternative Performance Measure)

Non-GAAP performance measure (EBITDA, underlying profit, like-for-like sales, etc.). Must be defined, reconciled to GAAP, explained, used consistently, NOT more prominent than GAAP. ESMA/FCA/FRC guidelines apply. IFRS 18 will require disclosure of "Management-defined Performance Measures" (MPMs) from 2027.

IFRS 18

Presentation and Disclosure in Financial Statements. Replaces IAS 1 from 2027. New SOPL structure with categories (operating, investing, financing); subtotals for operating profit and profit before financing and tax; management-defined performance measures disclosed.

Key Formulas

Worked Examples

Key Takeaways

  • IFRS Foundation governance: Monitoring Board (public oversight) → Trustees → IASB (accounting) + ISSB (sustainability). Due process: research → ED (90+ days) → redeliberations → final standard → PIR. UK post-Brexit: UKEB endorses IFRS for UK use. 8 of 14 IASB members approve standards.
  • UK GAAP framework: FRS 100 (application); FRS 101 (reduced disclosures for qualifying entities using IFRS recognition); FRS 102 (main UK GAAP for medium/small); FRS 105 (micro-entities). Key differences from IFRS: leases (operating off-BS — aligning 2026); goodwill (mandatory amortisation, default 10 yrs); revenue (simpler — aligning 2026); investment property (FV required); financial instruments (simpler).
  • UK regulators: FRC (standards, audit oversight, governance code) → being replaced by ARGA; FCA (Listing Rules, DTRs, listed disclosures); PRA (prudential reg of banks/insurers); UKEB (IFRS endorsement). Companies House (filings); HMRC (tax interest in accounting).
  • Sustainability reporting: ISSB sister to IASB. IFRS S1 (general requirements) and IFRS S2 (climate) effective 1 January 2024. Four-pillar TCFD structure (governance, strategy, risk management, metrics and targets). Scope 1, 2, 3 emissions; scenario analysis; transition plans.
  • EU CSRD/ESRS: more comprehensive, double materiality (financial + impact). UK: SDS being developed based on ISSB (investor-led financial materiality only). Multinationals may need to comply with both regimes.
  • Recent IFRS amendments: IAS 1 (current/non-current liabilities; material accounting policies); IAS 8 (accounting estimates); IAS 12 (DTA/DTL on single transactions; Pillar Two relief). IFRS 18 (2027) replacing IAS 1 with new SOPL categories.
  • APMs (Alternative Performance Measures): non-GAAP measures (EBITDA, underlying profit, like-for-like). Must be defined, reconciled to GAAP, explained, consistent, NOT more prominent. Common abuses: recurring "one-offs", selective exclusions. IFRS 18 introduces MPM disclosure requirements.
  • Current issues: cryptocurrency accounting (no specific IFRS — applying IAS 38 by analogy); rate-regulated activities; FRS 102 reform 2026 (revenue + leases convergence); digital reporting (iXBRL, ESEF). Public scrutiny of corporate reporting following major audit failures (Carillion, BHS) driving reform towards ARGA.
