The credits are tied to these jobs actually being created, so no jobs => no credits => no problem :)

I do not have any faith that government will actually enforce the requirement, I have seen it many many many where a company promises X number of jobs for Y tax break, then the actual jobs create is FAR FAR FAR less so the government just passed a new ordinance to adjust X to what ever the company did so they still get the credits even though that did not honor the original deal.
