Mr. Stephen Groarke:

We will come back to the committee with the specific dates. My understanding is that there was a variety of different contracts and there was not a hard cut-off between what we call the price promise and the appropriate rate. Even within those types of contract, there were variations. To my knowledge, there was no hard date before and after which we were offering different types of contracts.

I suggest we might come back with that detail because it is a more complex matter than the question assumes.
