Well, it's a good question. And Chris, maybe you can be helpful with this, because Grace, I hate to ask you because you're so brand new. But as we look to the model and built it in, everybody, all division leaders participate, you have the revenue growth, which is somewhat easier to predict because you can look at existing sales trends and build it up and we know from history what our accounts generally deliver and over what time period they generally deliver. So revenue tends to be the easiest part, Tien-tsin, of putting that plan together. What is somewhat more capricious is what cost will be involved, what initiatives that we don't announce on these calls because they're not yet public, we're working on and what that might cost and all that and how that plays into what the actual number will be. And then on the bottom line, how the depreciation and amortization schedules work in all the tax rates and tax credits, so that tends to be somewhat more difficult. So we feel pretty good about the revenue, and if we feel good about the rate -- well, we feel good about all of that, otherwise we wouldn't be guiding it. But I wouldn't say that the metrics in Q4 are the result of anything except, if you will, all the fewer cards from the risk controls sort of plateauing and then a reacceleration of growth with the first time we've had active card growth in quite a while showing that we're now building active cards. So if you think of the train of revenue, first you have to sell a card, then it has to be successfully activated, then it has to be used and reloaded and then the revenue begins so that growth in active cards and all the new rollouts in October, I would describe as the beginning, the engine of the train. And then as it flows through the year, it becomes fairly easy to predict if you were sitting in those meetings with us. So I think we have pretty good -- we have confidence. But of course, anything can go bump in the night and so we acknowledge that.
Tien-tsin Huang - JP Morgan Chase & Co, Research Division: Yes, totally understand. So just thinking about the margins, I know you've had a couple of questions on expenses. Just margin expansion of 30 bps. I think you've mentioned $10 million in incremental savings from the GE acquisition. So it does seem like you're spending a little bit more than average in '14. So just to put more detail to that, is it customer acquisition cost, proactive marketing? I don't think it's commissions, but just trying to -- a few more answers to that.
