An independent nonprofit education, research and advocacy organization, the American Antitrust Institute (AAI), sent a letter to the United States Sentencing Commission, asking the Commission to amend a key portion of the formula it uses to calculate fines for antitrust offenses. AAI requested that the Commission increase the standard presumption of illegal overcharge it uses to calculate fines from ten percent to twenty percent. If adopted, this increase would at least double the current fines for illegal price fixing and similar collusion offenses.
