Thank you, William. Thank you, William, and good morning, everyone. Thank you for joining us on our 2018 second quarter earnings results conference call. Michael Neidorff, Chairman and Chief Executive Officer, and Jeff Schwaneke, Executive Vice President and Chief Financial Officer of Centene, will host this morning's call, which can also be accessed through our Web site at Centene.com. A replay will be available shortly after the call's completion also at Centene.com or by dialing 877-344-7529 in the U.S. and Canada, or in other countries by dialing 412-317-0088.

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 filed Form 10-Q dated today, July 24, 2018, the 10-K -- most recent 10-K we filed on February 20, 2018 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. This call will also refer to certain non-GAAP measures, that’s Generally Accepted Accounting Principles, non-GAAP measures, a reconciliation of these measures with the most directly comparable GAAP measures can be found in our second quarter 2018 press release, which is available on our Web site at centene.com under the Investors section. Finally, a reminder that our third quarter earnings results call will be held on Tuesday October 23, at 8:30 Eastern Time, followed by our next Investor Day on Friday, December 14, which as always will be held in New York City. And with that, I'd like to turn the call over to our Chairman and CEO, Michael Neidorff. Michael?
