Toronto-based CI Financial Income Fund is planning to offer to buy DundeeWealth for about C$2.6 billion ($2.6 billion). The deal would produce Canada's biggest mutual-fund company. Bank of Nova Scotia, Canada's second-largest bank, recently offered to buy 18 per cent of DundeeWealth for C$348 million, or C$12.76 a share. CI’s unsolicited C$20.25 a share, stock only, offer is a 52 per cent premium to Dundee's closing share price of C$13.31. If the new deal goes ahead, each DundeeWealth share would be swapped for 0.75 of a CI Financial share, and CI would assume C$150 million in debt, as long as Bank of Nova Scotia's bid for the stake of DundeeWealth is abandoned.
