We think this is a really important change. Obviously we are facing demographic challenges in this country that are going to continue to make the provision of health care challenging. We recognize that, in many cases, people will need to have a doctor to provide services for them in their health care situation.
In many cases, though, nurse practitioners can play an important role. This measure was to acknowledge that as an important issue moving forward. We believe that by doing this, it will create an opportunity for our system to be more cost-effective and also to give people the appropriate level of care they need from the appropriate provider. It's recognizing expertise where expertise exists and being efficient at the same time, which is a very positive outcome.
