Yes. Simon, it's Nadir. Why don't I take the CapEx and then Bob can address any kind of technical question. I think if you slide back first, it really, to me, is a follow-on to the question we just had. We are absolutely committed to the strategy to drive growth in monetizing of data, and the backbone of that is IT-based networks that are conducive to data. So we're first with the LTE, we're the fastest. And in '13, we'll continue to rollout LTE to, I'll call it, a broader footprint. We have a couple of regions in the country that, Simon, and for competitive reasons, we won't get into specifics that we'll be targeting to shore up, I'll call it infill, and in some cases, scroll [ph]. And I think that will create more opportunities for penetration gain for ourselves, and I'm sure some of you will figure out where that is, but that shapes up the wireless side. A lot of like say the requirements on wireless now are frankly related to capacity and rolling out the backhaul and the requirements for data. On the wireline side, we continue to move forward in terms of what we would call setting up for IP networks and that means our chair [ph] of migration, that means faster speeds as we go forward, intensifying our network. And to a certain extent, we're also looking to expand a bit more into the business market where we're seeing great success, in fact, the limitation right now in terms of growing our market share has been very much where we have reached right to the business. So that's got some investment in there. And finally, speed, speed for Internet. We are the fastest. We firmly believe in remaining the fastest and all of that is contained in our guidance. The one last thing I'd say is that we feel we're very well positioned in Ontario, and we've got some shoring up that we'll be doing in the Atlantic to make sure that we're consistently fastest across our footprint.
