Have you tried removing some of the quad-spaces? The terms are arranged 
like this (pardon my ASCII art):

             XYZ
... =      -----       = ...
       ______ABC_bizbax

where the _ here represents literal spaces in. Presumably this is meant 
to align things just so, but it creates, well, a bunch of whitespace.
