3. Takata consider suitors: The troubled airbag maker Takata (TKTDY) is considering potential bidders following its deadly airbag recall.

Detroit-based company Key Safety Systems is a frontrunner for a deal.

An independent committee set up by the troubled Japanese firm recommended Key Safety Systems, Takata said in a statement over the weekend. It added that a final decision hasn't been made yet.

Key Safety Systems is the fourth-largest airbag maker in the world. Buying Takata would make it the second-largest, according to Valient Market Research.

Shares in Takata fell by 19% in Tokyo on Monday.
