MGM Assurance has penned a deal with Pavilion Asset Management which will see Pavilion managing MGM's £1.4bn in assets.
The agreement also sees MGM's investment director Gregor Logan joining the Pavilion Board as chief investment officer.
The new combined fund management team will operate out of MGM's City offices and comprise the majority of both existing teams.
After the deal, Pavilion now has £3.1bn under management.
MGM chief executive Gerard Healy says: “We are looking forward to developing the working partnership with Pavilion and widening the investment choice available to our policyholders, appointed representatives and supporting IFAs. We see this as bringing together highly complementary skills and believe it provides an excellent fit for all parties.”
