Disclosing Key Assumptions under IAS 36: A Practical Guide for High-Risk Sectors

In today’s dynamic business environment, assumptions play a critical role in financial reporting, particularly for companies operating in sectors exposed to significant climate-related and regulatory risks. IAS 36 Impairment of Assets requires entities to disclose key assumptions used in determining recoverable amounts of cash-generating units (CGUs). These assumptions are vital because even minor changes can lead to material adjustments in financial statements.

The International Accounting Standards Board (IASB), through its near-final illustrative examples, emphasizes the importance of transparent and comprehensive disclosure of such assumptions. This article explores how businesses should apply IAS 36 to enhance disclosure quality and build stakeholder trust.

IFRS Guidance on Assumptions Disclosure

IAS 36 requires disclosures about:

• Key assumptions used in measuring recoverable amounts, especially for goodwill and intangible assets.

• Approach to determining values assigned to those assumptions.

• Sensitivity analysis where a reasonably possible change could lead to impairment.

This information helps users assess the robustness of management’s judgments and the degree of uncertainty in valuation estimates.

Practical Application from IASB Example

The IASB’s illustrative example focuses on a high-emission entity exposed to greenhouse gas emission regulations. Here are key takeaways:

• The entity considers future emission allowance costs (price of emission allowances and regulatory developments) as key assumptions in its impairment test.

• These assumptions are reasonable and supportable, reflecting management’s best estimate of economic conditions.

• Disclosure includes:

  • Key assumptions such as future carbon pricing and regulatory requirements.

  • How these assumptions were derived and whether they align with external data.

  • Sensitivity analysis: Showing the impact on CGU value if assumptions change.

Insight: Businesses must go beyond quantitative figures and explain why assumptions were chosen, how they reflect expected future conditions, and their potential volatility.

Best Practices for Compliance

1. Identify Key Assumptions Early
   Focus on variables with the highest sensitivity—such as carbon prices, energy costs, or interest rates.

2. Document Assumption Sources
   Clearly indicate whether assumptions are based on internal projections, market data, or regulatory guidance.

3. Perform Sensitivity Analysis
   Disclose how much assumptions can change before impairment occurs.

4. Ensure Consistency
   Align assumptions across financial reporting, sustainability disclosures, and management commentary.

Strategic Insights for Businesses

Transparent disclosure of assumptions is not just an accounting compliance exercise—it’s a strategic communication tool. Investors and regulators increasingly demand clarity on how businesses plan for uncertainties such as climate change, regulatory shifts, and market volatility. Effective assumption disclosure:

• Enhances investor confidence.

• Supports ESG integration.

• Reduces litigation and reputational risks.

As business environments evolve and risks become more multifaceted—ranging from climate-related regulatory changes to economic volatility—the expectations of investors, regulators, and other stakeholders for clear, consistent, and comprehensive disclosures have grown exponentially. Transparency is no longer optional; it is a strategic imperative that directly influences market confidence and organizational credibility.

IAS 36’s disclosure requirements, combined with the IASB’s latest illustrative guidance, highlight the critical role of rigorous documentation of assumptions and sensitivity analysis in financial reporting. These disclosures provide stakeholders with valuable insight into management’s decision-making process, the resilience of cash-generating units, and the potential impacts of changes in key variables such as emission allowance costs, interest rates, and commodity prices.

For companies in high-risk sectors, the challenge lies not only in complying with technical IFRS standards but in ensuring disclosures are decision-useful—enabling investors to understand the uncertainties that could affect future performance. This calls for a proactive approach: integrating financial reporting with sustainability and risk management strategies, leveraging technology to model scenarios, and aligning disclosures across all corporate communication platforms.
