Tokio Marine Holdings expands risk management strategy with Cotality Insurance Solutions

IRVINE, Calif., August 14, 2025 — Tokio Marine Holdings, Inc., the holding company for Tokio Marine Group, one of the world’s largest and longest-standing insurance groups active in 45 countries, and Cotality™, a leading provider of property information, analytics, and data-driven solutions, have expanded their collaboration to help Tokio Marine companies better assess and manage the risk of secondary natural perils in the United States.

As part of this initiative, Tokio Marine Holdings is now leveraging the Cotality Severe Convective Storm Catastrophe Risk Model to more precisely evaluate property-level risk from severe convective storms—the most damaging secondary peril in the United States.

“In light of the recent experience with secondary perils we’ve placed greater emphasis on model validation and developing a more comprehensive view of risk,” said Luke Wood, VP Head of Nat Cat R&D at Tokio Marine Holdings. “Following thorough evaluations, we found the Cotality Severe Convective Storm model to be a robust model – in terms of methodology, components and loss validations - to further refine our view of risk leveraging available functionality. We look forward to partnering with the Cotality team of experts to enhance our view of severe convective storm risk in the U.S.”

The Cotality team constantly evolves its U.S. Severe Convective Storm Risk Model to reflect the shifting nature of these perils across the country.

“We’re committed to continuously evolving our models to reflect the real-world complexity of secondary perils,” said Mikhail Palatnik, Cotality’s Senior Vice President of Product Management. “Our work with Tokio Marine Holdings underscores how embracing advanced, data-driven solutions to navigate today’s risk landscape provides greater confidence and precision in managing risk.”
