Investa Listed Funds Management Ltd., the responsible entity for Investa Office Fund, is seeking more information as to how Investa Commercial Property Fund's recently confirmed strategic alliance deal with Macquarie Group Ltd. will affect Blackstone Group LP's standing A$3.14 billion bid for the fund.

As part of the Macquarie-Investa partnership, a 50% stake in Investa Office Management Holdings Pty. Ltd., the holding company to Investa Listed, was sold to Macquarie Real Estate Investment Holding (Australia) Pty. Ltd.

Investa Commercial said the platform transaction does not restrict it from voting on the takeover, pursuant to the s253E section of the Australia's Corporations Act, because its responsible entity and Investa Office Fund's manager are no longer associates to the Blackstone target.

However, Investa Listed said the law "is technical and complex" so it will need to examine whether or not Investa Commercial may vote on the takeover. It added that it asked Investa Commercial to confirm that all protocols and undertakings with Investa Office Management and Investa Property Group to protect Investa Office Fund are still in place and will be implemented and honored in light of the Macquarie deal.

Investa Commercial also said that it has not decided yet on how it will vote its roughly 19.9973% stake in the Australian office fund at an Aug. 21 meeting of Investa Office unit holders for the private equity giant's proposal.
