Liberty Mutual Foundation launches $600M endowment amid corporate giving uncertainty

Liberty Mutual Foundation has announced the establishment of a $600 million endowment, providing long-term funding stability amid uncertainty in corporate philanthropy. The Boston-based insurer's charitable arm will fund the endowment by transferring assets from Liberty Mutual entities. The move comes as corporate giving faces headwinds from tariff-driven uncertainty, rising costs and tax law changes. Foundation chair Melanie Foley said the endowment will enable increased grantmaking beyond its roughly $50 million annual baseline and provide security for nonprofit partners. The endowment will primarily benefit Boston-area organisations focused on housing stability, workforce development and climate resiliency. Liberty Mutual Foundation supported over 500 nonprofits last year, including the American Red Cross and Boys & Girls Clubs of America. The announcement places the foundation among those with over $100 million in assets.

Liberty Mutual and Floodbase launch instant parametric flood quoting for US commercial market

Floodbase and Liberty Mutual have launched an instant quoting application for parametric flood insurance in the US commercial market. The solution, powered by Floodbase Platform's new API, enables wholesale and retail brokers to price parametric flood covers in minutes, replacing a traditionally time-consuming process. The application targets small to midsized commercial businesses, where two-thirds of modelled US flood losses remain underinsured. Parametric flood coverage has matured as a complement to traditional property insurance, covering non-damage business interruption losses whilst addressing rising National Flood Insurance Program premiums. The new API allows brokers and managing general agents to integrate parametric flood insurance into automated quoting workflows, making previously bespoke placements accessible at scale. Liberty Mutual's pricing engine delivers multiple optimised structures and pricing options through the platform.
