Good morning and welcome to the United Therapeutics Corporation Second Quarter 2018 Earnings call. My name is Brian and I will be your conference operator today. All participants will be in listen-only mode until the question and answer portion of this earnings call. If you would like to ask a question during that time, simply press star then the number one key on your telephone keypad. If you would like to withdraw your question, press pound on your telephone keypad. I would now like to turn the conference call over to James Edgemond, Chief Financial Officer of United Therapeutics.
