That's my read of this.
ObamaCare gives HHS the authority to make unlimited grants to help states create Exchanges. But that authority expires on December 31, 2014. HHS just issued an announcement that they will issue grants right up to midnight on December 31—and that some of those grants will be so big that they will last for five years:
Q4: What is the last day that a State can spend its award?
A4: Grantees are encouraged to drawdown funding within their budget period (up to one year for Level One and up to three years for Level Two grants); however, at the recommendation of CCIIO’s State Officer and at the discretion of the Grant Management Officer, grantees may receive a no-cost extension that will allow them to spend funding up to the expiration date of the project period. At HHS’s discretion, a project period can be extended for a maximum of five years past the date of the award. Note, however, that all spending of §1311(a) funds awarded under a cooperative agreement must be consistent with the scope of the statute, FOA, and terms and conditions of the awarded cooperative agreement. [Emphasis added.]
The last sentence is there just to make sure no one suspects them of violating the law, wink-wink.
Since HHS can make unlimited grants in the first year that Exchanges are supposed to operate (2014), this means HHS is trying to pay for the operating expenses of some states' Exchanges for six years (2014-2019).
