On the first-time buyers versus existing customers, you've heard us say in the past that, historically, as a Company, we have been a roughly 50/50 mix of first-time buyers and existing customers. As 2008, 2009, 2010, 2011 rolled around, that number got to be 40% first-time buyers and 60% existing customers. We have said that we aspire to get back towards that 50/50 number. Exactly when that will happen -- whether that will be in two years or three years or four years -- I can't tell you, except to say that, that is our goal. And the reason for that is, why do we want more first-time buyers? Obviously, first-time buyers do a number of different things for us. A, they have a tendency to, over time, add more ownership during the course of their time. Secondly, they bring a new set of referrals to us that we have not heretofore seen. We get another management fee, another exchange company fee, as a result of all that. And, they have a slightly higher propensity to finance their purchase, which we make money off of financing. What happened in 2015 was a little bit of a pleasant surprise to us when we rolled out our new owner-recognition levels in the first quarter of last year. The take-up rate from our existing owners was meaningful, driving that 10% increase in contract sales on a quarter-over-quarter basis 2015 versus 2014. As a result, it kind of skewed that existing customer versus first-time buyer number by, call it 1 point, 1.5 points, something like that. So, when you get all that to the end of the year, we didn't make as much progress in 2015 as to changing the mix of first-time buyers and existing customers. I would say we moved it by maybe 1.5, 2 points, but we certainly have every intention and aspiration to do so further in the coming years.
