Armour said Jan. 3 that it has raised up to $500 million in equity commitments from an investor group led by Aquiline Capital Partners. Armour said it will use the funds to form a new reinsurance group, Armour Group Ltd, which will co-invest in global P&C run-off transactions in parallel with the group’s affiliates. The former Armour holding company is also renaming itself Trebuchet Holdings and transferring the Armour brand name to the new group.
