Yes Ann, this is Ed Rapp. I will cover that one. Yes, you know, needless to say we are watching it very close. As you pointed out, you know, past dues did grow to about 3.35% net, and that is up, you know, from the 2.09 last year. But, you know, if you look at the write offs net of recoveries, just you know, 19 million for the quarter versus 12 million for last year. So that shows you from a write off perspective, you know, very much I would say under control. If you look at, you know, our allowance to loss ratios, you know, I think being well managed and I think we're in a good position in that regard. So I think we are well below the last downturn. If you go back to 2002 and kind of look at those numbers, the past dues then peaked about 4.78, you know, versus that 3.35 we are having now. Another critical one is that if you were the write offs at that point in time, you know, we peaked at about a .69% of the average retail portfolio and that's kind of more than double the annualized rate we saw in the second quarter of this year. So yes, you know, there is the softening in North America and probably some risk there, but, you know, I think it is being well managed and it is well below the kind of peaks that we saw from the pressure on the financial side in the 2002 period. I think the other thing on Cat financial that's important to note is that in terms of new retail business they had a record second quarter, over $4.6 billion globally of new retail business. And I think it just shows the benefit of the global expansion of Cat Finance, where they are benefitting from some of the growth globally that we are seeing in other parts of the business. Access to funding continues to be good. You know, the recent issuance on medium-term notes have been oversubscribed in the three to four to one type ratio, so we still have good access to funds. And I think overall Cat Finance is kind of doing what we expect them to do is, you know, just deliver good, sustainable earnings through, you know, the peaks and valleys.
