Thank you very much.
We thank our guests for your attendance today. This is very helpful.
I'm trying to understand. Mr. McBain, in your earliest comments you talked about core and non-core activities. It would seem to me you have farmed out the non-core activities to various service providers, and that's been a function that you've handled, it would seem, since 1998.
What's the distinction between core and non-core services, the distinction between those things that you might farm out relative to those things that are maintained internally? Could you clarify that for me, please?
