AFTER_EQUAL takes two dates, and checks if the first one comes at the same time, or after the second.



AFTER_EQUAL(e.date_of_domicile, e.date_of_founding)

This expression checks whether a company gained domicile in its current country at the same time, or after it was founded. If the expression evaluates to 'true', the company could have been founded in a different country than where it is currently domiciled.
