Adverse Selection
The tendency for higher-risk insureds to seek coverage more aggressively, creating a pool skewed toward worse-than-average risks.
What It Is
Adverse selection occurs when there is an information asymmetry between the insured and the carrier, resulting in a disproportionate number of higher-risk entities seeking insurance. The insured typically knows more about their risk profile than the carrier, and those with greater exposure are more motivated to obtain coverage, while low-risk entities may forgo coverage or self-insure.
In commercial insurance, adverse selection manifests in several ways. A business that knows it has environmental contamination issues is more likely to seek pollution liability coverage. A company that recently fired its CFO and expects a lawsuit is more likely to pursue D&O coverage. A property owner in a flood zone is more likely to buy flood insurance than one on high ground.
Carriers combat adverse selection through underwriting, waiting periods, exclusions, and mandatory coverage pools. Detailed applications and questionnaires aim to reduce the information gap. Waiting periods prevent applicants from purchasing coverage after a loss has already occurred. Prior-acts exclusions in claims-made policies address known incidents. For some lines, like workers compensation, coverage is mandatory, which eliminates adverse selection by bringing all risks into the pool.
Why It Matters for Brokers
Brokers experience the effects of adverse selection when carriers impose restrictive underwriting requirements, exclusions, or surcharges on new business. Understanding adverse selection helps brokers anticipate why underwriters ask specific questions on applications and why certain coverages have extensive questionnaires. Brokers can also help clients obtain better terms by providing thorough disclosure that reduces the carrier's perception of information asymmetry.
Real-World Example
A technology company approaches a broker for its first cyber liability policy after learning that several competitors in its space have been breached. The carrier's application asks detailed questions about the company's security posture, recent security audits, and whether it has knowledge of any incidents. The company discloses a minor phishing incident that was contained. The underwriter offers coverage with a prior-acts exclusion for the 90-day period before the policy inception, addressing the adverse selection concern while still providing coverage going forward. Premium is $24,000 with the exclusion versus $31,000 without it.
Common Mistakes
- 1Advising clients to withhold negative information from applications, which both constitutes fraud and prevents the underwriter from properly addressing adverse selection through policy terms.
- 2Not understanding why underwriters impose restrictive terms on new business placements, missing an opportunity to negotiate by addressing the carrier's adverse selection concerns directly.
