Automobile Insurance Reform

Study guide: Exam 6C

Automobile Insurance Reform is the periodic legislative restructuring of a province's compulsory auto product — changing what is covered, who may sue, and how much benefit is payable — undertaken when premiums become politically unaffordable. Reform targets cost, because under rate regulation the only durable way to lower price is to lower the cost of the product.

\text{Premium} \approx \frac{\text{Frequency} \times \text{Severity}}{1 - \text{Expense \& Profit}}

• The reform cycle repeats across provinces and decades: costs rise faster than approved rates → affordability crisis and availability problems → legislative reform reducing benefits or access to tort → an initial premium reduction → cost creep back through claiming behaviour, judicial interpretation and inflation → the next crisis. Candidates should be able to narrate this cycle and explain why each stage follows.
• The levers, roughly in order of savings delivered:
  • Restricting access to tort — a threshold or deductible on pain-and-suffering claims.
  • Capping or defining benefits — the Minor Injury Guideline cap, Catastrophic Impairment definitions, medical/rehabilitation limits.
  • Converting coverage to first-party — Direct Compensation Property Damage, no-fault accident benefits.
  • Attacking cost drivers directly — fraud investigation, towing and storage regulation, treatment protocols, dispute-resolution reform.
• Estimating reform savings is the actuary's hard problem, and the standard errors are: assuming full and immediate effect; ignoring cost migration to the benefit heads left uncapped; ignoring behavioural response by claimants, counsel and providers; and ignoring judicial reinterpretation that erodes a definition over time.
• Savings emerge over the payout tail, so the first-year premium effect and the ultimate cost effect are different numbers. Filing one as the other is a classic error.
• Ontario (repeatedly since 1990) and Alberta (the 2004 minor-injury cap and subsequent reviews) are the two reform histories the syllabus covers in detail; the pattern in each is the same.

Pricing an Enacted Reform A province enacts a reform effective January 1 that caps minor-injury awards. An insurer's actuary must reflect it in a rate filing for policies written during the following twelve months. Bodily injury is 55\% of total loss cost, and industry analysis estimates the cap removes 20\% of BI cost.

The insurer's data covers accident years before the reform. Outline the calculation and the traps.

Answer The reform adjustment applies to the BI portion only:

\begin{align*}
\text{Savings} &= 0.55 \times 0.20 \\
&= 0.11
\end{align*}

So historical loss costs are multiplied by 1 - 0.11 = 0.89 to restate them at the post-reform benefit level, before trending forward.

The traps, each of which has produced a rejected filing:

• Order of operations. Restate to the current benefit level first, then trend. Trending unadjusted history and then applying the reform factor gives a different (and wrong) answer, because trend compounds on the pre-reform cost base.
• Trend period. Post-reform, the BI trend itself may differ from the historical trend — a cap converts part of a severity-driven trend into a frequency-driven one. Continuing to use the historical BI trend can overstate future cost.
• Migration. If minor-injury claimants shift to accident-benefit heads or press for a Catastrophic Impairment designation, part of the 20\% reappears elsewhere. A prudent filing quantifies this rather than assuming it away.
• Erosion. The 20\% is an estimate at enactment. Once courts begin interpreting the cap's boundary, savings historically shrink. The filing should say so and the FCT adverse scenario should test it.
