NGG earnings call for the period ending March 31, 2019.: Welcome to our full year results presentation and a special welcome also to everybody who's watching this online. As always, we're going to start with safety. There are no planned fire alarm tests this morning, so if you hear an alarm, we do need to leave the building through these doors and then out from reception. And I would also like to draw your attention to the cautionary statement that's included in your packs. And as always, there will be a Q&A at the end of this presentation.
