Spatial index has bounding box of -400, -90, 400, 90

I'm doing some inspection of the spatial indexes of various layers stored on our SQL Server.  Something I've noticed is that many of our WGS84 and NAD83 layers have a spatial index with a bounding box of (-400, -90, 400, 90). 


The -90 to 90 range on the y coordinates makes some sense, but where does the -400 to 400 range on the x coordinates come from?


Just for some context, these layers come from many different sources and have been added going back many years.  Most of these layers have an extent much less than the entire globe.


Can anyone explain how this bounding box was determined?  Is this a bad sign? Are we doing something wrong?


Thanks for any insight.
