We analyze whether or not the purpose of the concentration is to obtain dominance and whether or not competition in the market has declined. We have noted that the number of refineries has decreased, but that does not mean that we are finished with companies that may, according to our analysis, put pressure on the market. We believe, in fact, that the decrease in the number of refineries has led to greater efficiencies in the sector.
I will ask my colleague to say a few words about the comparisons that we have done, for instance, between the refinery margins in the United States and in Canada. The group of witnesses who follow us will be able to provide you with other details as well.
