General Motors has named Walter Borst as its vice president and Promark Global Advisors CEO, reporting to GM vice chairman and CFO Chris Liddell from 1 May.
Promark is a wholly-owned asset management subsidiary of GM focused mainly on the management of retirement plan assets, including GM’s pension plans assets.
Borst – GM vice president and treasurer since 2003 – will also continue as chairman of the Opel supervisory board.
“Walter has done an outstanding job as treasurer,” said Liddell. “He is a great fit to lead the team managing a crucial part of GM, the US$115bn in assets at Promark.”
Borst succeeds Nancy Everett, who has announced her intention to leave the company from 1 June. In 2007, Everett restructured the portfolio to hedge against volatility.
“Nancy was a valuable contributor during one of the most difficult times in the financial market’s history,” said Liddell. “Under her leadership, Promark delivered consistent performance for its clients, often outperforming the market.”
