Obamacare insurers will not receive any payments for the 2015 coverage year from a federal program designed to help them ease losses.

Insurers are asking for about $5.8 billion from the federal government for 2015 in Obamacare’s risk corridor program, according to an estimate from Brian Blase of the right-leaning think tank Mercatus Center. However, the Centers for Medicare and Medicaid Services said last week that all payments would go toward paying off the money owed the insurers for 2014.
