The access, as I say, will be available for costs incurred up to January 31, 2010. To the extent that you had a contract for, let's say, $30,000 worth of work and one-third of it had been completed by the end of January 31, you would have eligibility for that $10,000 worth at that point. It doesn't necessarily mean the whole project has to be done; only that for which you're going to claim the credit has to be done by that date.
On October 27th, 2009. See this statement in context.
