FAC Program Eligibility Deadline February 28
Under current law, Federal Additional Compensation payments of $25 weekly, funded by the American Recovery and Reinvestment Act, will not be available to people whose claims are effective after February 28, 2010. If your claim began prior to February 28, you will continue to receive the additional $25 weekly until your claim ends or until the program ends September 4, 2010, whichever comes first.

The U.S. Congress is currently considering legislation that would extend the eligibility time period for Federal Additional Compensation payments.

I knew they would have to mark a cutoff time, Im glad AWI posted something at least more than 5 days in advance. Bottom line is, you get it now then your good through Sept or when you claim exhausts.
