First of all, in the increase, you're right, the 2 big increase areas were the billing and the uncollectible. And the majority of that was due to the implementation of the new system, which as of '13, we stabilized ERP. We see '14 as the year to stabilize even further CIS and EAM. Also, the other increase, as you noted, that was temporary labor that we used and leveraging efficiencies of ERP. In terms of the decreases, we continue to look at preventative maintenance. We continue in terms of the implementation of automation, for example, across our system, looking at our -- the fastest and smartest technology for communication protocol of ensuring that we can commoditize the purchase of meters. We can tie it into reading pressure flows, et cetera. So in terms of decreases, we're working on all of those. Let me back up a little bit though. Remember the goal, the chart we showed at Investor Day. It's to hold O&M as flat as we can, and in order to offset the increased depreciation and amortization, which was $26.2 million incrementally higher in '13 and '12, and because we're investing, the capital significantly in '14 will also increase, we're having to look at all of the O&M expenses. So if I look at each category, there are certain things we can do in each category, but all of our employees and our teams have the goal of trying to keep O&M flat so that we can have experiences like I described in Indiana in the rate case. And we have the implementation of CIS, EAM. We have not seen the efficiencies yet from that because the implementation was in '13. This year, in '14, we will be looking to leverage those systems the way we are looking to leverage ERP and start seeing some of those over the next 1, 2, 3, 4 and 5 years. So we're just at the beginning of that process.
