Assurant had a decent thing going decided to dabble in the exchange and are now gone.
United had a decent thing going decided to dabble in the marketplace and is suffering huge financial losses.
Cigna pulls out of Florida three weeks before open enrollment due to fraud.
Assurant's market penetration was spotty at best before 2014. Their decision to enter the exchange had nothing to do with their losses. They still would have lost their arse as an off-exchange player only.
UHC sat out 2014 then decided to play in 2015. I suspect their recent backpeddling had more to do with seeing loss figures for 2014 players plus DC pulling the plug on reinsurance reimbursement.
Cigna was another minor player with a limited IFP footprint. Not the first time they have entered and then left the market.
