Thank you, operator, and good morning, everyone. Thank you for joining us on today's call. Michael Neidorff, Chairman and Chief Executive Officer; and Bill Scheffel, Executive Vice President and Chief Financial Officer of Centene, will host this morning's call. The call is expected to last about 45 minutes, and may also be accessed through our website at centene.com. A replay of the call will be available shortly after the completion of the call, also at our website, at centene.com or by dialing (877) 344-7529 in the U.S. and Canada or in other countries by dialing (412) 317-0088. The playback number for both of the call -- call-ins, is 10026527. Any remarks that Centene may make about future expectations, plans and prospects constitute forward-looking statements for purposes of the Safe Harbor provision under the Private Securities Litigation Reform Act of 1995. Actual results may differ materially from those indicated by these forward-looking statements as a result of various important factors, including those discussed in Centene's most recently form -- filed Form 10-Q, dated today, April 23, 2013, and other public SEC filings. Centene anticipates that subsequent events and developments will cause its estimates to change. While the company may elect to update these forward-looking statements at some point in the future, we specifically disclaim any obligation to do so. As a reminder, our next Investor Day is Monday, June 17, 2013, in New York City. Please mark your calendars for that. And also, later this morning, at 10:00 a.m. Central Time, we'll have a webcast of Centene's annual shareholders meeting available, and you can access that link at centene.com in the Investors section of our website. With that, I'd like to turn the call over to our Chairman and CEO, Michael Neidorff. Michael?
