"Humana announced that it expects to tap the three risk adjustment mechanisms in ObamaCare for between $250 and $450 million in 2014. This amounts to about 25 percent of the insurer's expected exchange revenue. This money is needed to offset losses that the insurer will take as a result of slower enrollment in its ObamaCare plans, and a skewed risk pool that weighs more heavily toward older and less healthy members than it originally budgeted. More than half of the money will come from the $25 billion reinsurance pool that ObamaCare provides (collected through a tax on employer-sponsored health plans). The other half will come mostly from the risk corridors."
