The Kinghorn family-controlled Sigma Alpha International has split up responsibility for research and advisory in the asset consultancy it purchased, CPG, with Brett Westbrook taking on a new role as well.

The new head of advisory at CPG will be Andrew Vallner, an actuary most recently at Denison but before that at CPG predecessor group Grove Advisory.

The managing director of Sigma Alpha International (SAIL), Graham Morrow, said Vallner had good relationships with local councils, of which CPG advises 45 around Australia.

Morrow said Vallner’s appointment would leave Simon Ibbotsen free to run the investment research function of CPG.

Brett Westbrook, meanwhile, will build the implemented consulting platform that will be branded under SAIL, but leverage the CPG investment research.

Despite the recent departures of veteran CPG consultants Peter Williamson, John Parrish and Phillip Chow, Morrow said most of the research “grunt” remained intact at the firm.

The frm’s largest advisory client remains its minority owner, WA Local Government Superannuation Scheme.

It recently lost an advisory contract with Amcor’s staff superannuation fund, which has switched, in the first instance, to an advisory contract with Russell Investments..
