Thanks, Madam Chair. So, yeah, it looks like there's more coming towards us in terms of O and M for roads that are built and we never really understand the O and M when we build them. But I had asked if any of this work is covered -- or should have been covered through any kind of guarantee or, you know, we build the thing, presumably the people that build it have some sort of responsibility to build it to some kind of standard and there's a guarantee period or something for performance. Are we outside of that range now so all of this stuff is coming out of our own pocket or is there any kind of guarantee period built into these things when we build roads. Thanks, Madam Chair.
