And then, in terms of the reduction in the brokerage count and the low-producing brokers, is it market conditions that are really driving them out, maybe to what extent are you squeezing them out? And when we think about a small producer versus a large producer, are you making money on the small producers, I assume you still are, or is that actually the small producers kind of a net negative for LPL unless they have a chance to really growing up to be much bigger? Is it kind of in your best interest to see them maybe move to a different career?
Mark Stephen Casady - Chairman & Chief Executive Officer: Well, I think you said it quite well. It's not unusual when you have moments of stress that somebody looks at the range of their economic activities. I grew up at a small town in Indiana, we have LPL advisors there, often that advisor will do the securities businesses, their primary means, but they may also be an insurance agent, they may also be an accountant. And so they have other businesses they're involved with. And typically in times like this, they assess, geez, my time better spent on one of the other activities where I can make better income or just, again, have a simpler life as things may go. So, it's exactly what you'd expect in the market where individuals make those decisions. It's also our business owners, remember that we have 4,600 business partners here who oversee their offices and their business and they're making a decision about exactly your point, which, is it economic to have this person in my space doing what they're doing, that may be in more a suburban location or even urban location, maybe they had someone who they put into place a couple of years ago and they're making decisions to see that that person isn't going to grow, as you suggest. And then finally, the third category are those that we look at, and again, reach that same conclusion. We've given them a couple of years, they haven't succeeded in the business the way we thought they would. And therefore, they're just not going to grow into something that makes sense for them to be involved in the business with us. Generally, we make money at lower levels of production, down to even $100,000 is just not a very much of a quantum of profits and the extent to which that takes away our focus from practices that are growing. We always want to focus on those practices that can grow and have good opportunity to continue to help their investors.
