The First Clerk was the official title for the personal financial assistant to the Grand Nagus. Grand Nagus Smeet and his First Clerk were both assassinated after a dramatic drop in the Ferengi Market Exchange. Quark briefly held this position until Grand Nagus Zek fired him for spreading rumors about Zek's lover and Quark's own mother, Ishka. (DS9: "Ferengi Love Songs").
