MBS MID MORNING: just a tick or two weaker

4.0's - 99-23

4.5's - 101-04

5.0's 102-03

All these levels a tick or two down from previous.

operational houskeeping note: we are spending a few days working intensively with our developers to roll out our new platform.  Today may be another day without a massive amount of content, but of course, we'll stay on top of price updates.  This is temporary and next week, things will be better than before.
