Summary
Sun Life Financial and Wilton Re have formalized a strategic partnership to create Windsor Life Re, a newly established reinsurer designed to scale the acquisition and management of life and annuity blocks. The partnership was announced on August 25, 2026, and involves a definitive agreement to deploy approximately $900 million in capital, with Sun Life and Wilton Re each committing roughly one-third of the total equity capitalization. The remaining capital structure details suggest additional third-party or external funding components to reach the full $900 million target.
Windsor Life Re will be domiciled in both the U.S. and Bermuda, positioning it to operate within multiple regulatory regimes while maintaining operational flexibility. The reinsurer will immediately assume an initial in-force block of approximately $1.7 billion from Wilton Re, with additional business expected to be ceded on a quota share basis going forward. At full scale, the vehicle is projected to manage approximately $10 billion in assets, reflecting the partners' ambitions to establish a significant player in the life and annuity reinsurance market.
Asset management capabilities will be anchored by SLC Management, Sun Life's global institutional alternatives platform, which has been designated as the lead asset manager for Windsor Life Re's investments. This arrangement leverages Sun Life's depth in insurance-linked asset management while capitalizing on Wilton Re's demonstrated expertise in identifying, acquiring, and optimizing in-force life and annuity blocks—a specialized skill set within the reinsurance sector. The partnership combines complementary strengths: Wilton Re's sourcing and underwriting capabilities in block acquisitions with Sun Life's institutional investment management and risk management infrastructure.
The transaction is subject to regulatory approvals and is expected to commence operations in the first half of 2027. Advisory support for the transaction included Jefferies and Sidley Austin on behalf of Sun Life, while Ardea Partners, Wells Fargo, and Debevoise & Plimpton represented Wilton Re.
