<s>[INST] The next text is a question of a member of the European parliament:"As part of the planned reform of the application of the rules on competition laid down in the Treaty, it is reported that the Commission is about to propose an overall reduction in the number of vertical barriers to trade.  Does the Commission realise that the proposed threshold of 40 % of market share might result in the closure of all the breweries in Luxembourg? Individual breweries there do have more than 40 per cent of market share, so they will no longer be able to conclude exclusive contracts. However, competing undertakings from the surrounding regions, which have less than a 40 % share of their domestic market but whose production is far greater than the entire production of Luxembourg, will be able to conclude such contracts. The small Luxembourg breweries will surely go under in the competition and survival war fought by the """"""""big names"""""""" which have extensive resources. That cannot be the objective of the new rules, and the Commission should realise this.  Is the Commission thinking of adapting its definition of the reference market to the situation in the real world, i.e. to define as a domestic market (of course, then with a lower reference figure for market share) the market in which actual competition ultimately takes place between undertakings? If not, would it not be more sensible for it to consider the supra-regional aspects of the innovations?"
