Interpretation boundary
HSR transactions are notifications reported under the federal premerger program, not a census of every U.S. merger. A reported transaction can involve multiple filings, and the adjusted denominator removes matters for which the agencies could not issue a Second Request.
Second Requests and public enforcement actions are different stages with different timing rules. Their counts must not be treated as a finding that every reviewed or reported transaction was anticompetitive.
Early termination statistics reflect requests and agency action under the rules operating in each fiscal year. Policy and publication changes make this series unsuitable as a standalone measure of enforcement intensity.
