I thank our guests for their opening statement. I listened to their comprehensive views, and while I had to step out of the meeting for a few moments to attend the Seanad, I heard the vast bulk of their and members' contributions. Hardly a debate goes by in which Brexit is not mentioned, and it has become part of our being, our fibre and everything we do and think about, whether that is flights, roaming charges, exports or operations. We all know people who work in multinationals and small businesses, and the revenue of the State will be affected one way or another by it.

Forecasts are forecasts and models are models, but will our guests give us some insight into how the modelling works? What are the variables that produce the outputs?
