The Department of Finance, in the previous budget, said they would look at it, so they had a series of consultations about the tax credit. They talked to a number of folks about it and I think made some small modifications to it.
Iain can add to that, but the holder of that public policy instrument is the Department of Finance, given that it's a tax measure. In the context of your committee's work, you might want to invite somebody from the Department of Finance to come and talk specifically about the tax credit.
