Generally the way we underwrite development deals is that we use our market forecast for rents, the same market forecast that drive our operating assumptions and all that. So they could be flat, they could be up. In majority of cases, today they're up, and actually we've been exceeding those expectations and pretty much most of the development that we've been stabilizing. So in other words, we've been underestimating rental growth. Cap rates, by and large, we don't underwrite cap rate compression in our developments at all. In fact, I would say that in a few of them right now we have baked in some cap rate -- slight cap rate expansion. So I think the normal margins, as you've heard me say many times, I think in a normalized market when you're buying land at markets, for spec should be around 15 and for a very high credit build-to-suit should be as low as 10, so the average should be 12, 13, 14, depending on the mix. So you can think of -- forget about the 38. The 38 is just a goofy number in some unusual cases. It's real money but it's not a sustainable number. I think, yes, we've been averaging in the high teens, call it 19, and if the average is 14, should be, that means there's 5 points of excess margin and if land is 25% of the total investment, 5 points on 25% means that your land is undervalued by 20%. That's the quick math. It depends on parcel by parcel, but that would be the quick math. So I don't know, our land bank is $1.8 billion, and if you apply the 20% to it, you could argue that it's worth $350 million, more than that.
