Royal London Asset Management has been appointed by the Northern Ireland National Assembly's pension trustees to manage members' pensions.
RLAM will now manage funds worth £3m after winning what it describes as a competitive tender for the business.
The fund will form part of RLAM's pooled pension fund launched last June.
RLAM has £18bn in funds under management, including around
£2.5bn from institutional pension funds. The company says it has won seven out of 14 pitches for pension funds over the last 12 months.
Director of sales and marketing Howard Daldorph says: “We are delighted to have been awarded the mandate after a competitive tender.
“The appointment continues our successful start to the year and reaffirms our determination to broaden our UK client base.”
Northern Ireland National Assembly chairman Denis Watson says: “RLAM offered a compelling investment track record and an intelligent outlook.
The managers have a structured and disciplined approach to stock selection, which it clearly delivered in the past.”
