The John Turner Construction Group has completed a full scheme buy-in with Aviva.
The deal, which was completed in March, secures the benefits of 18 deferred members and one pensioner.
The deal was completed without additional funding from the sponsor, and full buyout and wind-up will now take place.
Broadstone provided investment, administrative, actuarial and annuity broking services while CMS provided legal advice.
Aviva bulk purchase annuity deal manager, Andrew Shaposhnikov, said: "We're pleased to be the provider that's given long-running support to the scheme and look forward to working with Broadstone and the trustees to complete the final steps in the scheme's risk reduction journey. The scheme transacted through our new streamlined service, Aviva Clarity, which underlines our commitment to helping well-prepared schemes of all sizes, to secure member benefits via a simple, robust, and efficient process."
