On September 16, 2010, the United Kingdom's Office of Fair Trading (“OFT”) and the Competition Commission (“CC”) published the final version of their new joint Merger Assessment Guidelines (“Guidelines”). The Guidelines expand and revise the previous guidance published separately by OFT and CC in various publications and attempt to clarify the 2002 Enterprise Act.
Key revisions compared to previous guidance include the following:
New Guidelines expand the concept of 'theories of harm' and uses such theories in assessing whether or not a substantial lessening of competition (“SLC”) has been created by the merger. The Guidelines explain that a merger gives rise to an SLC when it has any impact on rivalry that is likely to cause harm to customers. Therefore, evidence on likely adverse effects will be a key factor in the assessment.
