According to letters filed on the Federal Trade Commission (FTC) website, the matter was investigated after Zuffa purchased Strikeforce for a reported $34 million dollars in 2011.
The investigation was to see if Zuffa was in violation of Section 7 of the Clayton Act or Section 5 of the Federal Trade Commission Act.
In both cases, the FTC found that Zuffa did no wrong doing in their business dealings to acquire the MMA promotion.
According to the letter issued by Secretary Donald J. Clark, “This action is not to be construed as a determination that a violation may not have occurred, just as the pendency of an investigation should not be construed as a determination that a violation has occurred. The Commission reserves the right to take such further action as the public interest may require”
The FTC was alerted to Zuffa purchasing Strikeforce by a letter from the Culinary Worker’s Union in Sept 2011 claiming the company was violating anti-trust laws.
After the investigation was conducted by the FTC, no such violation was found to have occurred.
