Not necessarily bad design, Dennis.  Optionality (zero-or-one to one 
relationships) can be considered here.  For example, a Mortgage 
application done in a single table might have 200 fields, 100 of which 
were irrelevant if the applicant didn't pass the first qualification review.  
Why waste all that unused space in your design?
