- cannot help you there, Bruce, but in the UK every company with sensible SOPs will say 'YES'.
EUOPS says:
"..the commander shall declare an emergency when calculated usable fuel on landing, at the nearest adequate aerodrome where a safe landing can be performed, is less than final reserve fuel."
but does not specify the 'may be less' than scenario which is where a PAN call is normal - but that is really commonsense..
