Full press release

Legal & General (‘L&G’) today announces that the L&G Mastertrust has passed £20bn in assets under management (AUM)2 , making it the first commercial master trust in the UK to reach the milestone.

Established a decade ago as one of the first master trusts in the UK, the L&G Mastertrust today supports 275 participating employers, looking after the retirement savings of over 1.8 million members. In the past two years alone, the Mastertrust’s AUM has grown by 67%, the number of participating employers by 53% and the number of underlying members by 50%3.

Since the introduction of auto-enrolment in 2012, the master trust market has continuously evolved to meet the investment, cost and governance needs of employers and employees, aiming to combine the benefits of scale and flexibility to help deliver the retirement outcomes that members deserve.

The L&G Mastertrust’s investment proposition seeks to meet the changing requirements of members both up to and into retirement. Supported by Legal & General Investment Management (LGIM), the largest UK-based asset manager, the L&G Mastertrust has prioritised sustainable returns4 , flexible decumulation options and increasing the role of private markets across the Mastertrust’s default funds to achieve greater diversification and potential sources of returns across asset classes.

At the same time, the L&G Mastertrust has prioritised the member experience in the administration of their pensions, supporting employers and members through challenging periods such as the Covid-19 pandemic and the current cost-of-living crisis to prioritise resilience, long-term retirement outcomes for the UK population. 

These objectives are underpinned by the scheme’s robust governance, led by the Board of Trustees. Earlier this month, Legal & General announced the appointment of Robert Waugh as the new Chair of Trustees for the L&G Mastertrust5.

Legal & General supports over 4.7 million members across its Defined Contribution (DC) business as the largest provider in the UK6.

Stuart Murphy. Co-Head of Defined Contribution at Legal & General Investment Management (LGIM): “We’re proud that so many clients have put their faith in us over the years by choosing to join the L&G Mastertrust. Becoming the first commercial Mastertrust to reach £20bn in AUM is a real achievement for the scheme, testament to the hard work of our investment team, the scheme’s administrators and the board of trustees, who have delivered excellent outcomes across the day-to-day running and governance of the Mastertrust.

“We believe our scale enhances our potential to offer greater financial stability, further investment in services and economies of scale which can help to deliver value for members. Looking ahead, our ambition is to continue to build on our scale, improving retirement outcomes and financial wellbeing for members, while contributing to a better future through responsible investing.”

Dermot Courtier, Independent chair of the L&G Mastertrust: “This latest milestone follows significant announcements from the L&G Mastertrust Trustees in recent years, including the launch of a Member Advisory Panel, which invites a group of members to meet quarterly with Trustees and provide feedback, as well as the Mastertrust’s public Net Zero commitment. The Mastertrust Employer Group, which brings up to 100 employers together every quarter, celebrates its 10-year anniversary this year.”
