"The board also sought advice on the DNZ proposal, noting that there is a lack of clarity or certainty in this proposal at the current time," MFL said.
DNZ wanted to take over Argosy and challenged a $32.5 million internalisation payment to current management-contract holder, ANZ's OnePath.
"That sum has since been lowered to $20 million but the deal is yet to be voted on.
"MFL believes there is merit in exploring merger opportunities in addition to and alongside corporatisation, and has sought assurances from the Argosy independent directors that they will actively pursue these objectives for the benefit of all Argosy unitholders as soon as internalisation has been achieved," MFL said.
"Achieving internalisation is the preferred outcome, with the benefits fully accruing to Argosy unitholders.
"MFL does not want to put that outcome at risk while other alternatives are explored, which would likely see the benefits of internalisation shared."
