Section 8 of the Clayton Act,as modified by the Antitrust Amendments Act of 1990,prohibits the same individuals from controlling competing corporations when those individuals are:

A) shareholders.
B) directors or senior officers.
C) mid-level officers.
D) managerial employees.

Until 1990,the statute's prohibition against interlocks was limited in scope because it barred only interlocking directorates.Nothing in the original language of Section 8 prohibited a person from serving as an officer of two competing corporations,or as an officer of one firm and a director of its competitor.The Antitrust Amendments Act of 1990,however,expanded the scope of the statute by including senior officers (defined as officers elected or chosen by the board of directors)within its reach.
