Prosperity
Prosperity was a state of heightened financial well-being.
Upon his retirement from being the Grand Nagus, Zek appointed Rom to be his successor, explaining the role metaphorically as "It's a great responsibility to stand at the bow of the Ferengi ship of state. A Nagus has to navigate the waters of the Great Material Continuum, avoid the shoals of bankruptcy and seek the strong winds of prosperity." (DS9: "The Dogs of War")
