John Dawson
Management
Okay. Good morning, ladies and gentlemen. I am John Dawson, Head of Investor Relations at National Grid, and it's my pleasure to welcome you here today to National Grid's first half results presentation for 2012-'13. Shortly, I'll hand you over to Steve Holliday who will kick off the presentation. But before I do, a few notices. Before we start, can I please ask you, as usual, to turn off your mobile phones, and as usual, we will have a question-and-answer session at the end, could I ask you to you to use some microphones, and please state your name and organization. In today's presentation, Andrew and Steve will refer to various profit and other measures, unless otherwise stated, these will be adjusted for timing of storms and all operating profit and interest costs are at constant currency. Finally, our presentation today may contain forward-looking statements. I need to draw your attention to the cautionary statements in the presentation and in your pack and at the start of the online presentation for those dialing in. Please refer to these when you consider our comments today. Just a reminder, you will find all of the materials for today's presentation and additional fact sheets on our website and on our Investor Relations app. Without further ado, let me hand you over to Steve.
