New for 2015: Obamacare insurers' opt-out clause

“These insurers will sell you some Obamacare—at least as long as the government is footing the bill for most of their customers.
Insurers doing business on HealthCare.gov will be allowed to terminate their health plans if there’s a halt on federal tax credits that help most Obamacare customers buy the coverage, according to new language for 2015 contracts.
The language giving insurers the new opt-out does make clear, however, that individual state laws still may force insurers to continue the coverage.”
