Specialty insurance underwriting plays a critical role in markets shaped by dislocation, heightened uncertainty, or generally greater complexity. Typically, higher margins are required to compensate for higher levels of volatility, but navigating this volatility is no easy task.
What Is Specialty?
Around 1000 BC, David defeated the larger, better-armed Goliath with a sling and a stone, highlighting that battles can be won through scale (Goliath) or skill (David). In insurance, neither is inherently superior, and many companies use both scale and skill across teams, business units, or subsidiaries.
Specialty risks are those excluded from standard insurance. Take inland marine, which covers property that is in transit, is under construction, has high values, or has other idiosyncratic traits. This could run the gamut from medical equipment to infrastructure to bitcoin mining to fine art. These are all excluded in common property coverage, and each requires a highly bespoke solution.
There are four types of specialty insurance risk:
Expertise. These risks require a deep understanding of the exposure and underlying loss drivers, along with prior experience and a healthy dose of battle scars. Classic liability examples would be grain elevators, snow-plow operators, or liquor liability. Inland marine is the quintessential property example. Tax liability is a niche professional lines class, focused on unintended tax liability associated with transactions or other changes in tax treatment.
Structure. These are property and liability coverages with unique structural characteristics. The classic example is excess & surplus, where freedom of rate and form gives underwriters flexibility on terms and pricing. Alternative risk transfer, often for larger clients, similarly varies retention, limits, caps, coverage options, and more. Channel relationships (binding authority, MGAs) may also include variable, loss-sensitive performance features.
Dislocation. For these, the demand for insurance exceeds the supply, resulting in excess rate. Often, the lack of supply is due to loss-driven distress, leading to the pullback of capacity. Cat-exposed property generally represents this risk in any hard market point in the cycle.
Service. These risks require solutions in addition to risk transfer, which in turn requires non-insurance expertise. Examples include property engineering, cyber risk mitigation, or auto telematics. The intention could be to prevent or mitigate loss or provide some insight that allows an insurance carrier to have superior risk selection.
These archetypes aren't mutually exclusive, as some businesses can have several of these features. I tend to de-emphasize certain specialized risks, especially those with higher volatility across the insurance cycle such as terror or remote-return-period property, like earthquake or other non-peak zone perils. These can be profitable but (in my view) resemble picking up pennies in front of a steamroller. It works until it doesn't, and when it goes bad, the losses can be severe.
Specialty can also mean emerging risks with little track record and higher uncertainty, such as intellectual property or contingency, two of the more recent P&C market innovations – which also happen to be distressed insurance products where ultimate losses were underestimated.
Specialty Underwriting Requires Slingshot Precision
Specialty underwriting is about skill over scale. It requires more nimbleness, creativity, and precision than standard risk. There are six core pillars of great specialty underwriting:
1. Scale within the niche. Average line size needs to be balanced relative to the total portfolio. Losses inevitably will happen, and without scale there is less room for error. Balance is commonly measured by premium-to-limit ratios, to ensure there is enough depth to reasonably absorb loss when it happens.
2. Surgical underwriting thesis. Every specialty segment needs a clear rationale. The underwriter might have some unique edge or expertise. In any case, markets inevitably shift, and usually specialty niches become less attractive over time once the crowd catches on and there is more capital availability. Cycle management is a critical feature for any underwriting thesis.
3. Quantifying upside and downside. It's difficult to plan for precise outcomes, particularly in a short horizon. Underwriters need to understand the stochastic distribution of results – the probability of profit relative to the probability of loss. Underwriting and actuarial need to be deeply intertwined with underwriters who understand the quantification of the upside/downside, and actuaries needing business judgment, so the quantification is not mechanical and superficial.
4. Street smarts. It's critical to understand when math might be wrong and avoid over-reliance on models. This applies to any catastrophe model, any probable maximum loss (PML) calculation, and any return on capital model with diversified capital. Street smarts means appreciating that models are directional at best.
5. Exceptional talent. Great specialty portfolios are built by talented and passionate underwriters. Not just technically strong but with market followership across all stakeholders: brokers, reinsurers, and other underwriters. Great underwriters are humble, appreciating what is unknown. The best underwriters have passion, which they exude when they talk about their business.
6. Portfolio Balance. Given specialty's inherent volatility, it requires a portfolio of niches, ideally with non-stacking, non-correlating exposure. Diverse exposures will lower the standard deviation of results, meaning, the overall average performance should be less volatile. Portfolio breadth also allows more flexibility to dial up or dial down specific niches in response to the market cycle. There is a critical caveat, the need to avoid "de-worsification." Every niche needs to have a strong thesis and favorable outlook, or it risks dragging on results.
Conclusion
Like David defeating Goliath, specialty underwriting is all about precision and skill honed through practice. Success in specialty lines requires ensuring every line has a clear thesis for market success, a path to scale within the niche, and the right balance of risk and reward.
