A Managed Meta Data Term - Where is it being used?

Hi,

I have a number of Terms in my Managed Meta Data Term Store that I would like to delete.  Before deleting I need to know in which lists/libraries in my farm they are being used.

Is it possible to find out where a term is being used in the farm?  Moving the term is not an option.  Is my only option to Deprecate the terms and see who complains?

Thanks in advance,

Mark
