Which Nigerian Banks Has A Principal Manager Grade?

I have heard of the following grades in Nigerian banks:

Executive Director
General Manager ---------------------(SVP)
Deputy General Manager --------------(VP)
Assistant General Manager ------------(AVP)
Principal Manager
Senior Manager ----------------------(SEA)
Manager -----------------------------(EA)
Deputy Manager
Assistant Manager
Senior Banking Officer
Banking Officer
Assistant Banking Officer
PIT

It appears most banks do not use the Principal Manager grade, can bank workers please state their bank and help confirm if their bank uses it or not?

Also where in the grades does a First Vice President in UBA's capital markets fall?
