One thing I am a little curious about, and something that IR wasn't able to answer, is why property operating expenses and taxes have both been increasing pretty significantly over the last few quarters. Not sure if it's a function of the renovated properties or not, but in order to get an accurate NOI figure, we really need to know where property operating expenses and taxes cap out. Do they increase forever as properties are redeveloped or should that expense growth taper off at some point? Any ideas?
