Key benefits of parametric insurance

Icon

Transparent Terms

Policies are built on measurable triggers—like rainfall or temperature—so clients and their brokers know exactly when payouts occur. No fine print, no ambiguity.

Icon

Fast, Predictable Payouts

Once a triggering event occurs, payment is issued quickly and automatically—no need for on-site assessments or lengthy claims processes.

Icon

Customized Coverage

We work closely with brokers to build each policy around the client’s specific risk and budget profile, providing protection where traditional insurance often cannot.

Flexible Use of Funds

Payouts are based on the severity of natural events occurring, not solely on proven losses, giving clients immediate access to funds and empowering them to cover any type of financial loss, not just for physical damage.

Tornadoes are a recurring and destructive peril in Oklahoma, often impacting large areas in a matter of minutes. For Native Nations, these events can disrupt economic activity, cultural preservation, and essential community services.

Parametric Tornado Solution for Native Nations in Oklahoma

A Native Nation in Oklahoma faced significant disruption following a damaging tornado event.

Problem

A Native Nation in Oklahoma was impacted by an EF-2 tornado. The local government realized that their traditional insurance policy provided insufficient coverage for property damage across wide areas, including visitor centers and cultural landmarks. As a result, repairs were delayed, postponing the reopening of centers and historical sites. The extended closures disrupted community engagement, reduced visitor traffic, and led to increased financial losses.

Solution

To address this coverage gap, the Native Nation relied on Descartes’ EF Scale Tornado parametric insurance. Once the insured location was hit, the policy triggered a swift payout based on the pre-agreed EF Scale payout structure, enabling the community to resume operations without unnecessary delay.

Result

For this event, with an aggregate limit of $20 million, an EF-2 tornado would trigger a 60% payout, resulting in a $12 million payout to support repairs, reopening efforts, and financial recovery.
