The nonprofit shareholder representative As You Sow filed a lawsuit in the federal district court for the District of Columbia to compel the insurance company Chubb Limited to include As You Sow’s climate change-related shareholder proposal in the proxy materials for Chubb’s 2026 shareholder meeting. The complaint described the proposal as asking Chubb to “commission a report assessing whether it would benefit Chubb and its insureds for Chubb to pursue compensation from responsible third parties to offset the cost of insuring against losses stemming from climate change.” The complaint alleged that Chubb gave notice to the U.S. Securities and Exchange Commission on January 13, 2026 that it intended to exclude the proposal from its proxy materials on the grounds that the proposal qualifies for an exception to the rule requiring inclusion in proxy materials of properly submitted proposals. The exception cited by Chubb applies to proposals that deal with matters relating to the company’s “ordinary business operations.”
