The factors that are generally taken into account in determining whether restrictions in vertical agreements fall within the scope of Article 101(1) are listed in the Commission`s vertical guidelines, namely: suppliers` position on the market; the buyer`s position in the market; competing market positions; barriers to entry; ready to be placed on the market; the level of trade concerned by the agreement; and the nature of the product concerned. The position of suppliers in the market is probably the most important of these factors. Explain the analytical framework applicable to the assessment of vertical restraints in relation to anti-dominant positions. Are there general exceptions to the anti-dominant rules for certain types of agreements that contain vertical restraints? If so, please describe. .
