Risk corridor data released on October 1 by the administration shows that insurers lost a lot of money on Affordable Care Act (ACA) plans in 2014. The ACA established a three-year risk corridor program to transfer funds from insurers with lower-than-expected medical claims on ACA plans, i.e., profitable insurers, to insurers with higher-than-expected claims, i.e., insurers with losses. Despite administration claims that incoming payments from profitable insurers would cover losses from unprofitable ones, the risk corridor program shortfall exceeded $2.5 billion in 2014. Insurers with lower-than-anticipated claims owed about $360 million, and insurers with higher-than-anticipated claims requested about $2.9 billion from the program.
