Aetna is the latest of the big five U.S. health insurers to announce its withdrawal from exchanges selling subsidized health plans. It is withdrawing from 11 of 15 state exchanges, established under the Affordable Care Act to provide a centralized market for standardized policies eligible for subsidies. The law, usually known as Obamacare, is reducing the number of uninsured, with about 13 million people signing up for plans in the year ending in February. But some private insurers, needed for the whole setup to work, seem unable to make money.
