Early retiree insurance costs are significant for many employers, and one of ObamaCare’s selling points was $5 billion in new funds to be given away to companies to cover those costs. But the fund won’t help much and businesses won’t get the benefits they were promised, because the fund is so small it will quickly run out. “Confusion over how the money will be distributed is frustrating employers, consultants and applicants say. ‘They’re already getting nervous,’ said Derek Guyton, a partner and actuary with human resources consultancy Mercer LLC in Chicago. ‘At some point, the money will just run out,’ he insists. Mr. Guyton said midsize employers are questioning whether it’s worth applying for the funding since it requires time-consuming calculations.”
