HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF 1976
A law passed by President Ford that requires large companies to file a report with the Federal Trade Commission and Department of Justice before completing a merger, acquisition or tender offer so that government regulators can determine whether the transaction would violate antitrust laws.
The Hart-Scott-Rodino Antitrust Improvements Act of 1976 requires any investor seeking to acquire a 15% stake or a stake valued at more than $15 million in a security to file with the government. The form is called a premerger notification report (PNR), with the filing marking the beginning of the 30 day review. The acquiring company must also pay a filing fee which can change from year to year.
