Our Business

The services and insurance coverages we provide protect our clients, allow them to rebuild after major losses and help families build wealth through homeownership. Helping our clients manage uncertainty begins with assessing and addressing risks and collaborating to build resilience in a world facing heightened climate perils and evolving societal demands.

Enterprise Risk Management Strategy

Our Enterprise Risk Management (ERM) team formally identifies and integrates sustainability topics, including climate change and climate-related risks, into our Risk Register and extends that analysis to specific climate-related business risk evaluations in line with the Taskforce for Climate-related Financial Disclosures (TCFD) recommendations. With a focus on sustainability performance, we annually review these evaluations and validate the underlying data annually. See our TCFD Report (page 7).

  • Risk management responsibilities are delegated across our organization through a “Three Lines of Defense” approach to risk governance. See the detailed table below.
  • The Board and its committees oversee governance, operations and executive performance, with sustainability risks integrated across key risk categories. These risks are outlined in our policies and in assigning committee responsibilities. See our Definitive Proxy Statement on Form 14A, filed with the Securities and Exchange Commission on March 24, 2026, pages 14-17, for a detailed description of our Board and committees’ oversight responsibilities.
  • Specific areas of research and focus in 2025 included U.S. wildfires; Hawaiian, Caribbean and Indian tropical cyclones; Canadian severe convective storms; and Italian natural catastrophes.

Evaluating Environmental Exposures: Our Approach

As a global insurer, we integrate environmental considerations into underwriting decisions for thermal coal-related business. This policy applies to our global insurance operations and covers existing and new thermal coal mines and coal-fired power plants. Underwriters must identify high-risk accounts, defined as insureds that derive 30% or more of revenue from thermal coal mining or power generation. Through our governance process, flagged accounts are escalated for review. Our UK insurance companies also apply sector-specific guidelines for Arctic energy exploration and production and oil sands mining and surface extraction. These policies define the scope and screening parameters for the assessment and escalation referral process for business accounts in these environmentally sensitive sectors.

Powering Progress: Next-Generation Energy Solutions

We are taking steps to address climate challenges and support our insureds through our specialty insurance products and solutions:
