Thank you.
This morning you, Ray, from SARM, asked us to continue with OUI. Jill, I've heard you say, and I think your recommendation states, that we should move quickly to the GROU program for this year. Given that it was not as effective as we had expected it to be, why would you continue to ask us to move towards GROU?
I'd appreciate a brief answer, because I have a number of other questions.
