OMERS subsidiary invests in IOF as plot thickens over ownership of vehicle. : Australia’s Investa Commercial Property Fund (ICPF) has agreed to sell half of its 19.99% stake in Investa Office Fund (IOF) to Oxford Properties, the real estate arm of Canadian pension fund OMERS. As part of the arrangement, ICPF said it will not vote in favour of Blackstone’s AUD3.1bn (€1.98bn) bid to take over IOF which was due to be held at an extraordinary shareholder meeting next week. The move follows a number of ownership changes relating to ICPF and IOF, two large core Australian property funds.
