(22) Commission Notice: Guidelines on the effect on trade concept contained in Articles 81 and 82 of the Treaty (‘Guidelines on the effect on trade’) (OJ C 101, 27.4.2004, p. 81), section 2.4. The Commission may use market shares to assess whether there may be an effect on trade, but that assessment does not necessarily require that relevant markets be defined and market shares calculated (see paragraph 48 of the Guidelines on the effect on trade), and the Commission is under no obligation to do so.
