Corporate Reporting · Advanced Level
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:
| Body | Role |
|---|---|
| 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:
- Research / agenda decision: identify potential project; staff papers; consultation
- Discussion paper (optional): preliminary views; broad public consultation
- Exposure Draft (ED): detailed proposals; minimum 90-day public comment period
- Redeliberations: IASB considers comments; may issue revised ED
- Final standard: published with Basis for Conclusions explaining decisions
- 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:
| Standard | Applied 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:
| Framework | Focus | Status |
|---|---|---|
| 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:
- Define: explain how the APM is calculated
- Reconcile: to nearest GAAP measure
- Explain why used: relevance to investors
- Consistency: same definition each period (changes explained)
- NOT MORE PROMINENT than GAAP measures: GAAP must come first
- Comparatives: at least one year of comparative APM
- Identify items excluded: explain what makes them "exceptional" or "underlying"
Common APMs and considerations:
| APM | Common use | Concerns |
|---|---|---|
| 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

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.
