Major Companies to Drop Presciption Drug Benefits Under Obamacare?

From the AP:

"The health care overhaul will cost U.S. companies billions and make them more likely to drop prescription drug coverage for retirees because of a change in how the government subsidizes those benefits.

In the first two days after the law was signed, three major companies — Deere & Co., Caterpillar Inc. and Valero Energy — said they expect to take a total hit of $265 million to account for smaller tax deductions in the future."

"Generally, retirees would prefer to stay with prescription drug coverage provided by their companies as opposed to enrolling in a Medicare Part D plan, said Marilyn Moon, a health care economist with the nonpartisan American Institutes for Research.

She said most of the company-sponsored plans are more generous and almost none have the coverage gap that comes with Part D plans."

UPDATE: Ed Morrisey at Hot Air elaborates:

"Over the past year, I’ve repeatedly warned about the dangers of static tax analysis. That process considers changes in tax policy without considering its impact on behavior. The closure of this 'loophole,' as Robert Gibbs called it yesterday, is a perfect example of this stunted thinking.

The Democrats in Congress argued that they would gain $5.4 billion in revenue by eliminating the tax break enacted in the 2003 Medicare Part D program as an incentive for businesses to keep their retirees out of the Medicare system. Instead, they have given businesses a reason to dump their retirees out of the private networks and into the Part D system now. Not only will the expected tax revenues never appear, but now we will have to spend a lot more money covering those prescriptions out of public funds. The seniors in these programs will suffer most of all, as the Part D coverage is vastly inferior to the private plans offered by businesses in the private sector."
