SEI announces acquisition of Atlas Master Trust from Capita

In October 2021, SEI announced the acquisition of Atlas, Capita’s defined contribution (DC) master trust. Subject to regulatory approval, the deal extends a successful, long-term strategic partnership between SEI and Capita and positions the SEI Master Trust to continue delivering best-of-breed service at scale.

If ‘master trust’ reads as yet another confusing financial term, allow us to tell you what it really means for your organisation and pension scheme members.

By definition, it’s a framework that combines workplace defined contribution pension schemes from different employers under one organisational umbrella.

But by our reckoning, it’s much more.

One hundred and forty-six thousand members with approximately £2.0 billion* in the SEI Master Trust can look forward to a better retirement by virtue of the value for members that our economies of scale provide.

Other master trusts can legitimately make the same scale claim but few can call on investment expertise responsible for overseeing over £1 trillion* in assets globally.

This capability sets us apart in the master trust market. For 50+ years, SEI has been a growing force in helping everyone—from institutions to individuals—invest towards their unique goals guided by our global outlook and reach.

Combine these qualities with a 15-year track record in running a master trust in the UK and we believe our solution is clearly worth considering.

Ultimately, we believe in looking after your members brilliantly - up to, into, and through retirement.

Decades of investment know-how has informed our constant refining of technology to sharpen performance and focus on outcomes, giving our independent trustee board powerful tools to deliver on those beliefs. Download our brochure below to find out more.
