The partnership will be capitalized at approximately US$900 million, with Sun Life and Wilton Re each contributing roughly one-third of total equity capitalization, alongside a third capital source. Windsor Life Re will operate as a U.S. and Bermuda-domiciled reinsurer, establishing a foundation for sustained growth through Wilton Re's established sourcing and underwriting capabilities. The vehicle will initially reinsure an in-force block of approximately US$1.7 billion from Wilton Re, with additional future business to be ceded on a quota share basis, enabling both organic and acquisition-driven expansion.

SLC Management, Sun Life's global institutional alternatives asset manager, has been designated as the lead asset manager for Windsor Life Re and will have the authority to manage up to US$10 billion in total investments. This arrangement leverages SLC Management's established expertise in insurance asset management and its diversified multi-asset investment platform, designed to optimize returns while maintaining appropriate risk parameters for reinsurance operations.

The partnership is structured to capitalize on Wilton Re's longstanding track record in in-force block acquisitions, its deal sourcing capabilities, and its specialized underwriting expertise in life and annuity business. By combining these capabilities with Sun Life's institutional asset management platform and insurance infrastructure, the partnership positions Windsor Life Re to compete effectively in a concentrated market for block acquisitions.

Windsor Life Re is expected to commence operations in the first half of 2027, allowing time for regulatory approvals, capital deployment, and operational infrastructure development prior to launch.
