Why it Matters?

Per se treatment eliminates the procompetitive justification defense entirely, which means the litigation concentrates on whether an agreement existed rather than whether it harmed competition. Information exchange among competitors is the recurring gray area, since sharing current pricing data can support an agreement inference while exchanging historical aggregated data through a neutral administrator generally does not. Compliance program design turns on that distinction.
