Sure. And the competitive frame has certainly evolved. And while we at one time thought that many of the new entrants might show up to be competitors in the new undergraduate, not-for-profit, four-year loan origination business, that has not really materialized. And so, we think about the competitive frame, one for new undergraduate, not-for-profit, four-year loans, that frame has remained relatively static. On the other hand, as had been discussed already in this call, there are a series of people who are reaching for growth and looking to do refinancing. And while we are the largest private student loan provider of funding, remember that that market is only a $10 billion in originations each year as a ballpark number and that the federal government is putting out about $95 billion in additional balances each year. So, when we look at the sheer bulk of student loan funding, it is certainly not with us. Having said that, people have come and gone over the last couple of years in regard to both fin tech efforts as well as the ability for them to put those items on either their balance sheet or to pass these assets through to an ultimate investor. So, there's been quite a bit of volatility if we look at the list of people who would be our talking points two years ago versus today in the refi market. Having said all that, as Steve correctly points out, our refi for us has this most activity when a person graduates from school, has their six months of freedom before they have to make a payment, shows up and all of a sudden they have a bill that’s due sort of this month. And so, there's a natural tendency to say, boy, how do I get my average cash flow to be a little more positive each month. Look around for refinancing and sometimes they find it, sometimes not. If, however, if nothing occurs during that first 16 to 18 months of activity, it tends to be the case the portfolio settles down, people just doing what they are doing, the payment becomes automatic and we move along. So, the competitive frame for the originations hasn't changed much. The competitive frame in regard to refis has changed quite a bit. Some players in, some more aggressive. It has been noted some of the economics are relatively unfavorable. And our portfolio, as it matures, goes through a period when people consider other payment options and then they move along. And so, we're watching this segment by segment. As Steve says, the sum total of all the activity in regard to both the originations as well as the refinancing has caused us to revamp our thinking on the average life of a loan that would be originated this afternoon from 6.2 years to 6.1 years. And has not changed at all our ROEs or our cut-off decisions in regard to the amount of risk we can take given the revenue stream.
