CBO said that this year's tax cuts have changed the incentives for businesses and made it less attractive to pay for insurance, meaning fewer will decide to do so. Instead, they'll choose to pay a penalty to the government, totaling $13 billion in higher fees over the next decade.
This. One of my clients who has five years to go before he can retire from Eastman Chemical, just last week told me that Eastman Chemical is dropping their insurance coverage and is electing to pay the $10,000,000 annual fine because the fine is cheaper. I haven't seen or read anything else to corroborate this, though.
