IFRS 17's Big Judgment Call: Nailing Your Risk Adjustment Confidence Level

IFRS 17 has introduced several new concepts, but few provoke as much discussion as the Risk Adjustment for non-financial risk (RA). Think of the RA as the 'price of uncertainty'—the compensation an insurer requires for bearing the unpredictable nature of insurance claims. At the heart of this calculation lies a critical judgment call: selecting the confidence level. This single choice significantly impacts your balance sheet and profit emergence, making it a key focus for management, auditors, and investors.

So, What Exactly is a Confidence Level?

In simple terms, a confidence level represents the probability that the provisions you’ve set aside (your best estimate liability plus the RA) will be sufficient to cover future obligations. If you select a 75% confidence level, you are essentially stating that you are 75% confident your reserves are adequate. A higher confidence level, like 90%, implies a larger RA buffer, reflecting greater prudence and a higher degree of certainty.

The Core Dilemma: Freedom vs. Justification

IFRS 17 doesn't prescribe a specific confidence level. This flexibility allows companies to reflect their unique risk profiles and management philosophies. However, this freedom comes with a significant responsibility: you must disclose and rigorously justify your chosen level. The decision creates a direct trade-off. A higher confidence level leads to a larger RA, lower day-one profits, but potentially smoother profit release in the future. A lower confidence level results in a smaller RA and higher initial profits, but greater volatility in future earnings if experience turns out worse than expected.

The Three Pillars of a Strong Justification

How do you build a defensible and logical case for your chosen confidence level? Your justification should stand on three core pillars.

1. Alignment with Corporate Risk Appetite

Your RA confidence level should not exist in an accounting vacuum. It must be a direct reflection of your company's overall risk management framework and stated risk appetite. If your board has approved a risk appetite statement that emphasizes capital preservation and earnings stability, a higher confidence level is a natural and justifiable choice. The key is to create a clear, documented link between your strategic risk philosophy and your IFRS 17 accounting policy.

2. The Nature of the Insurance Risk

Not all risks are created equal. The characteristics of the underlying insurance contracts should heavily influence your confidence level. For example, a portfolio of long-tail liability business, with its inherent uncertainty and potential for extreme events, would warrant a higher confidence level than a predictable, high-frequency, short-tail motor insurance portfolio with extensive historical data. Key factors to consider include contract duration, data quality, and the complexity of claim patterns.

3. Consistency and Comparability

While you can use different confidence levels for different portfolios, the principles behind those choices must be consistent. Stakeholders, especially analysts, will be looking for a coherent story. You must be able to explain why one portfolio is assigned an 85% confidence level while another is at 75%. Documenting a clear methodology for setting confidence levels based on risk characteristics ensures internal consistency and enhances the credibility of your financial statements.

More Than Just a Number

Selecting and justifying the RA confidence level is far more than a technical compliance task. It is a strategic communication tool that tells a story about how your organization views and manages uncertainty. A well-justified confidence level demonstrates a deep understanding of your business and provides stakeholders with valuable insight into the prudence and risk philosophy embedded in your financial results.
