Thank you for the question.
It does indeed depend on the sector; there is no magic threshold.
We have guidelines for mergers, for example. A 35% threshold is an indicator that there might be competition problems. For example, there would be a problem if the market share was higher than 35% after a merger. The act, however, does not allow us to challenge a merger solely on the basis of concentration thresholds.
You really have to look at each sector individually. It depends on the facts and the data. Concentration is an important factor when we look at competition.
