Consider a merger of two firms (each with a 25 percent share) who compete with five smaller firms each with a 10 percent share. (This generates a post-merger HHI of 3000)

Moreover, assume the merger will generate some efficiencies, but also draws complaints from three customers.

A detailed analysis concludes that the market is correctly defined and barriers to entry exist. However, the evidence supporting a competitive concern is mixed as the five fringe firms might be able to expand to restore competition. (This is assumed to result in one disagreement in the staff analyses.)

Finally, the review indicates that only 30 percent of the business of the acquired firm is in the market of competitive concern.

Summing up, we find:

• HHI - 3000

• Efficiencies - 1

• Customer Complaints - 3

• Disputes - 1

• Overlap - 30

If the user desires to include the overlap variable this should generate an 88 (88.16) percent change of a complaint.
