As Street Talk revealed, IOOF's board was due to sign off on the final details at a meeting on Sunday night after its deal team, including banker Citi and law firm Allen & Overy, secured the acquisition agreement with NAB.
IOOF is expected to pitch itself as the largest wealth manager in Australia - bigger than the biggest bank-owned platform, Westpac, and bigger than long-time rival AMP.
