Report: Private equity partners up for Arconic bid

A group of four large private equity firms are working on a joint bid for aluminum parts maker Arconic, per Reuters.

Why it's a big deal: Because this could signal that big buyout firms are beginning to get over their decade-old aversion to large club deals.

Plus, Arconic remains under pressure from aluminum tariffs, including ones on Canada that were not rescinded as part of the recent trade deal.

• The club reportedly includes The Blackstone Group, The Carlyle Group, Onex Corp. and Canada Pension Plan Investment Board
• Apollo Global Management was first mentioned as a suitor back in July, and reportedly remains interested.
• Arconic has a market cap of around $10.5 billion, plus another $5 billion in debt.
