VIA Rail Canada, Montreal, is planning to increase its exposure to alternatives. The C$1.4 billion (U.S.$965 million) defined benefit plan is considering the move as a result of a recently completed asset allocation study. The rail system expects a high rate of return and will diversify its portfolio, said Chris Caswell, director of corporate financial services. In addition, VIA will consider adding currency overlay management. Mr. Caswell cited the plans high foreign exposure and its need to manage risk as reasons for adopting currency overlay. There is no timeline for a decision, he said.
