Ms Derville Rowland:

In respect to the price differentiation, before we sent out that letter we had already had meetings with the different businesses to establish what they tell us their practices are. We wrote the letter to be clear and specific about our high-level intent, and we have been told by some that they are not operating any price differentiation. We have been told by others that they actually charge existing customers less than new customers, and we have been told by others that new customers get discounts. That is only from our point of view the tip of the iceberg, because that is at a preliminary level. Precisely because we need to establish in a great degree of granularity - because of the new innovations - what is going on, we are doing this deeper investigation as we discussed at the specific hearing addressing that. I hope that answers Deputy Doherty's question.
