Definition: Trading style
Legal persons often use initials, an acronym, or a trading style instead of their official name in their business or administrative relations. The official name of a local unit is generally the same as the enterprise that controls it, though different local units within an enterprise may use different trading styles (also known as "signboard names" or "commercial names").
