SWITZERLAND – Swissca Portfolio Management’s chief executive Roman von Ah has left with immediate effect, the company said in a statement.

The board of directors of Swissca Holding announced that Dr von Ah would be leaving as a result of “diverging opinions about management and organisation”. Andreas Suter, also a member of the executive board of Swissca Holding, and chief financial and logistics officer for the parent, is leaving for the same reason.

Hans-Joerg von Euw, a member of the executive board of Swissca Portfolio Management, will take over Dr von Ah’s role as chief executive on an interim basis. Gerard Fischer will permanently replace Suter.

A spokesman said that the replacement process would soon be underway.

Swissca Portfolio Management is the subsidiary of Swissca Holding, a company owned by the Swiss cantonal banks. Swissca Portfolio Management manages the Swissca funds, cantonal bank portfolios and pensions.

It manages 31 billion Swiss francs (19.8 billion euros).
