Why employer-sponsored health care is headed for a fall — in one revealing chart

By shifting insurance to the employee, the Affordable Care Act presents an opportunity for U.S. companies to radically redefine the role they play in the health care system.

The ACA could save S&P 500 companies nearly $700 billion through 2025, about 4 percent of those companies’ current market capitalization.

If all U.S. companies with 50 or more employees made the switch, the total savings to businesses could be as high as $3.25 trillion through 2025.

The shift benefits employers the most as the government and consumers take on a larger funding role.
