IFRS 17, a few years in: what it actually changed

Few topics have dominated the insurance industry over the last decade quite like IFRS 17. There were project teams, steering committees, consultants, model rebuilds, system migrations and enough workshops to last several careers.

Now that implementation is largely complete, many Actuaries, students and insurance professionals still have the same question: what actually is IFRS 17?

The good news is that the core idea is much simpler than most presentations make it sound.

The 30-second explanation

IFRS 17 changed when insurance companies recognise profit. That's it. Not cash. Not premiums. Profit.

Under the old accounting standard (IFRS 4), insurers had considerable flexibility in how they reported results. IFRS 17 was introduced to improve consistency, transparency and comparability across the industry.

Profit should be recognised as insurance services are provided, not simply when cash is received.

If an insurer receives a premium today for five years of insurance coverage, IFRS 17 says the profit should emerge gradually over those five years. Simple concept. Extremely complex implementation.

Think about Netflix

Imagine you buy a Netflix subscription for the next 12 months. Netflix receives your money today. But have they earned all of that revenue immediately?

Not really. They still owe you twelve months of service. Most people would agree it makes sense to recognise that revenue gradually over the year.

Insurance works in a similar way. Just because an insurer receives cash today doesn't mean all of the associated profit belongs to today. The insurer still owes future insurance coverage.

Why did IFRS 17 happen?

Before IFRS 17, comparing insurers could be surprisingly difficult. Two insurers selling very similar products could report very different profits. Investors wanted:

• Better transparency
• Better comparability
• Better visibility of future profitability
• Better understanding of risk

IFRS 17 was designed to provide exactly that.

What actually changed?

Insurance companies still collect premiums, pay claims, pay commissions, buy reinsurance and manage expenses. The economics didn't change. The reporting did.

A useful way to think about it: IFRS 4 asked "Did we make money this year?" IFRS 17 asks "Where did we make money, have we actually earned it yet, and how much uncertainty remains?"

The reporting is far more granular and far more focused on future profitability.

The big idea: matching profit to service

This is the most important concept in IFRS 17. Imagine an insurer sells a five-year policy today. The company might already know the policy is expected to be profitable. But has it earned all of that profit yet?

No. It still has five years of insurance coverage to provide. IFRS 17 therefore tries to match profit recognition with insurance service delivery.

The insurer earns the profit gradually as it provides coverage — not simply when the premium arrives.

The famous CSM (without the jargon)

One of the most talked-about IFRS 17 concepts is the Contractual Service Margin (CSM). The easiest way to think about the CSM is as a bucket holding future profit.

Imagine an insurer sells a profitable policy and expects to make €100 profit overall. IFRS 17 doesn't allow the insurer to immediately recognise the entire €100. Instead:

• The expected profit goes into the CSM
• The CSM sits on the balance sheet
• The profit is released gradually over the life of the contract

The profit exists. It simply hasn't been earned yet.

What about Risk Adjustment?

Another important concept is the Risk Adjustment (RA). Think of this as a margin for uncertainty.

A simple analogy: you estimate a house renovation will cost €20,000. Experience tells you unexpected things always happen. So you budget €23,000 instead. That extra €3,000 is effectively a contingency buffer.

The Risk Adjustment works similarly. Insurance claims are uncertain. The RA reflects the additional compensation an insurer requires for accepting that uncertainty. Higher uncertainty generally means a larger Risk Adjustment.

The simplified IFRS 17 flow

At its simplest, every insurance contract looks something like this:

• Premium received
• Expected claims
• Expected expenses
• Risk Adjustment
• Future profit (CSM)
• Profit released over time

This is effectively the journey from premium received to profit recognised.

The concept everyone remembers: onerous contracts

This is where IFRS 17 became much stricter. Suppose an insurer sells a policy today and the Actuaries estimate: premium €1,000, claims €850, expenses €100, Risk Adjustment €100. The economics suggest the policy will lose money overall.

If you already know the business is expected to lose money, don't wait years to tell investors. The loss must be recognised immediately.

These are called onerous contracts.

Why would a product lose money on day one?

A common reaction is: "surely insurers don't knowingly sell loss-making business?" Usually they don't. But several things can create an expected loss:

• Aggressive pricing — cutting prices to win market share until premiums no longer cover expected costs
• Inflation — claims costs rising faster than expected, motor being a classic example
• Poor assumptions — claims frequency, severity or policyholder behaviour differing from expectations
• New products — limited historical experience, greater uncertainty, higher chance of losses

What happens when a contract becomes onerous?

This is where the phrase "profits are recognised gradually but losses are recognised immediately" starts to make sense.

If the contract is profitable, expected future profit goes into the CSM and emerges gradually over time. If the contract is loss-making, there is no future profit bucket. Instead:

• The expected loss hits the P&L immediately
• A loss component is established on the balance sheet
• Future reporting reflects that loss position

Good news is delayed. Bad news is recognised immediately. Accountants call this prudence. Most investors would call it common sense.

Why does this matter?

IFRS 17 makes poor-performing business much easier to identify. Management teams can no longer rely on future profitable business to mask loss-making portfolios. Investors can more easily see:

• Poor pricing
• Weak underwriting
• Deteriorating claims experience
• Unprofitable growth

As a result, there is often greater focus on writing profitable business rather than simply writing more business.

Why Actuaries suddenly became even more important

One of the biggest consequences of IFRS 17 was how closely Actuarial and finance teams became linked. Before IFRS 17, Actuarial models and accounting systems could often operate relatively independently.

After IFRS 17, cash flow projections, assumptions, reserving and future profitability all matter more. Actuarial models now directly influence reported profits, balance sheet values, insurance revenue and financial reporting.

The accounting standard may have been written by accountants. But much of the information feeding it comes from Actuarial models.

Why did implementation cost so much?

Students often ask why insurers spent years implementing this. Because IFRS 17 wasn't just an accounting update. It required changes across:

• Actuarial models
• Finance systems
• Data infrastructure
• Reporting processes
• Governance frameworks
• Controls and audit procedures

Many insurers effectively rebuilt large parts of their reporting ecosystem. For some companies, implementation programmes lasted several years.

A few years later: was it worth it?

Opinions remain mixed. Supporters argue IFRS 17 provides better transparency, comparability, visibility of future earnings and understanding of profitability. Critics argue it introduced significant complexity, higher reporting costs, more operational burden and greater reliance on assumptions.

The truth probably lies somewhere in the middle.

What students and early-career Actuaries should know

You do not need to become an IFRS 17 expert overnight. Most qualified Actuaries only work with parts of the framework. However, understanding these concepts will help enormously:

• Profit is recognised over time
• Future profits sit in the CSM
• Risk Adjustments reflect uncertainty
• Loss-making contracts are recognised immediately
• Cash flow modelling drives much of the reporting
• Actuarial models now play a larger role in financial statements

Those ideas alone will put you ahead of many graduates entering the profession.

Final thoughts

A few years after implementation, IFRS 17 has become part of everyday insurance reporting. The project teams have largely disappeared. The consultants have mostly moved on.

What remains is a framework designed to make insurance profits better reflect economic reality. Whether it achieved that perfectly is still debated. But one thing is certain: IFRS 17 permanently moved Actuaries closer to the centre of financial reporting.

If you remember only one thing: IFRS 17 is about matching profit to service. If the profit relates to future coverage, it is recognised gradually. If a loss is already expected, it is recognised immediately. Everything else is really just detail.
