Mechanics:

• Each Australian Accounting Standard specifies applicability and any Tier 2 disclosure exemptions (paragraph 10; BC81–BC83).
• Entities applying Tier 2 cannot claim compliance with IFRSs (paragraph 14).
• First-time adopters and entities moving between Tiers follow specific transition rules, which may require applying AASB 1 (First-time Adoption) or using the AASB 108 retrospective route, depending on whether the entity previously applied the recognition and measurement requirements (paragraphs 17–23; 18A; 19–20A; Appendix C and D).
• Short-term and targeted transitional reliefs are provided for some entities (see Appendix E and the amendments described in the Compilation Details and Basis for Conclusions on subsequent amending Standards such as AASB 2014‑2, AASB 2020‑2, AASB 2022‑2).

Who pays and who decides

• Who pays: entities preparing GPFS pay the compliance costs — accounting, restatement, audit and internal systems work required to meet Tier 1 or Tier 2 requirements, and any one-off costs when transitioning between bases of accounting (see BC11–BC13; BC88–BC96; paragraphs 18–21).
• Who decides: the AASB sets the two-tier framework and identifies additional Australian-specific entities deemed publicly accountable (Appendix B; BC26). Individual entities decide whether to elect Tier 1 where eligible (paragraph 13; BC39; BC60). Regulators can require Tier 1 for particular entities (paragraph 15; BC40–BC41).

Incentives, trade-offs and implementation risks (mechanisms, not judgments)

• Incentives:

  • Entities may choose Tier 1 voluntarily to state IFRS compliance or to meet parent or investor expectations (paragraphs 13–14; BC39; BC60).
  • Eligibility for Tier 2 reduces ongoing disclosure costs by design (paragraph 9; BC19).

• Trade-offs and opportunity costs:

  • Tier 2 reduces disclosure burden but prevents stating IFRS compliance (paragraph 14), so an entity trades lower disclosure cost for the loss of an IFRS compliance statement.
  • Transition choices (apply AASB 1 vs AASB 108) change the extent of retrospective restatement required and therefore affect costs and comparability (paragraphs 18–20A; BC11–BC13; BC17–BC21).

• Implementation risks and compliance burden:

  • Determining whether an entity is publicly accountable or which regulator will require Tier 1 may involve judgement and coordination with regulators (Appendix A and B; BC26; BC61–BC65).
  • Transitioning entities may incur significant effort to restate comparatives, consolidate for the first time, or remeasure assets and liabilities, and the Standard contains detailed, varied rules depending on prior reporting (paragraphs 18–21; 19B; 20A; BC88–BC96; BC5–BC24 of the 2022‑2 Basis for Conclusions).
  • Multiple cross-references to other Standards (notably AASB 1 and AASB 108) and accompanying guidance increase procedural complexity (paragraphs 17–23; Appendix C and D; BC8–BC21).

Concentrated benefits, diffuse costs and discretionary points in the law

• Concentrated benefits: entities that qualify for Tier 2 (non-publicly accountable entities) receive the direct, ongoing benefit of reduced disclosures (paragraph 9; BC19).
• Diffuse costs: users of financial statements and regulators may face some loss of disclosure detail; the Standard relies on regulators to require Tier 1 where needed (paragraph 15; BC40–BC41).
• Points of discretion: the AASB clarified Australian-specific categories of publicly accountable entities (Appendix B; BC26) and delegated to other regulators roles in tier determination (BC40–BC41). That regulatory role creates a locus of decision-making outside the Standard itself.

Transitional relief and temporary measures

• Appendix E lists optional short-term exemptions for certain entities applying Tier 2 early (E1–E7), for example relief from distinguishing correction of errors from changes in accounting policy for some early periods, and relief from restating comparatives in limited early-adoption cases (Appendix E paragraphs E1–E7).
• Subsequent amendments (see Compilation Details and Basis for Conclusions on AASB 2014‑2 and AASB 2022‑2) adjusted transition and reapplication rules in response to practical concerns such as entities that previously prepared special purpose financial statements or unconsolidated Tier 2 GPFS being required to present consolidated GPFS for the first time (see BC2–BC4 of AASB 2022‑2 and paragraph 20A).
