AMP has so far been unable to sell its private markets business to US-based Ares Management Corporation, after a preliminary agreement lapsed.
The wealth manager on Monday said the 30-day heads of agreement with Ares to sell AMP Capital's markets business had concluded.
The two businesses continue to work on a sale.
In October, Ares offered to buy AMP but talks fell through. The two later tried for a joint venture on the markets business.
Shares were down 0.56 per cent to $1.33 at 1102 AEDT.
