HG: Good afternoon everybody. Your Excellencies I'm Hadley Gamble on CNBC anchor in the Middle East and I'm joined now by the CEO of NASDAQ. I want to kick off by market volatility we've seen so much movement in pricing over the last several days in particular. We've a lot of comments about this. I got to speak with Christine Lagarde head of the IMF. She was essentially saying to me that this was a market correction this wasn't something that she hadn't been expecting at some point in the future. But I want to ask you about what that means in terms of the markets themselves. There's a lot of speculation about what's been behind these price moves and has it been technologies has it been algorithm's has it been a guy are you concerned at all about what we've seen over the last several days in terms of the regulation.
