How Parametric Insurance Can Help Your Commercial Clients

When traditional coverage leaves your clients vulnerable to exclusions or sublimits, or when protection against specific perils is simply unavailable, it’s time to take a different approach: parametric insurance.

Parametric insurance has been around for many years, but with increased data granularity and availability, these special policies are now widely available to fill coverage gaps under admitted policies. This new approach is made possible by recent advances in data collection, artificial intelligence (AI)-powered analytics and the Internet of Things (IoT).

Unlike traditional indemnity products, where claims are adjusted, parametric insurance has a fixed payout based on pre-negotiated limits for pre-defined event severity. Parametric solutions are invaluable for insuring a range of risks, from weather-driven construction delays to flood, wildfire, named windstorms, tornado and hail events. Because parametric coverage is not tied to physical damage, it can cover the full economic impact of a loss event, even without physical damage to insured property.

An increasing number of carriers are using complementary parametric solutions to underwrite difficult natural perils because they cover the occurrence of the event rather than the impact of the loss, offering much greater certainty and much faster payment. With more predictable claim sizes, carriers can evaluate their total exposure across risk classes with greater accuracy and efficiency, allowing them greater comfort in insuring against more difficult perils.

The clarity and transparency of parametric triggers and contracts allow the insured, the broker and the carrier to know exactly what is due—with claims settlements made in days, not months or years.

Parametric insurance is a helpful tool for the hospitality sector. For example, the operators of a Florida resort saw that a major hurricane landing near them could cause a long-tail revenue loss. The resort had traditional business interruption coverage with its property policy, but it came with many limits and restrictions that required physical damage to the insured property for the coverage to kick in.

The building was constructed to withstand events up to a Category 3 hurricane with no physical damage, but the area around the resort—the main draw for tourists—could be heavily impacted. The operators would suffer not only an immediate revenue loss from the few days preceding and during the hurricane, but also the extended decline in revenue from the “loss of attraction,” which occurs when tourists change their vacation plans.

That long-term income impact, along with the costs associated with preparing for the storm, cleaning up debris afterwards, and even physical damage if it did occur, is all eligible loss under the resort’s parametric hurricane policy. It covers the full economic impact of an event from the first dollar lost and can be utilized in many unique ways. The speed of claims settlement is a bonus, allowing the insureds to begin recovery significantly faster.

Parametric insurance is also gaining popularity within the construction sector. Lenders financing the construction of an office block may insist on flood insurance during the build. However, it is almost always excluded from builders risk policies. Parametric flood coverage utilizing on-site sensors fills that gap. It can cover material costs and any liquidated damages the builder might incur due to construction delays.

Parametric insurance has evolved in many other ways to provide bespoke protection against clients’ difficult-to-insure risks. It is now widely used to transfer away many risks which have traditionally been considered uninsurable. Because underwriters insure the event, not the loss, prior claims history is not a factor in the rating, and policies cover the full economic impact.
