Article 8

For the purposes of applying the market-share thresholds laid down in Article 3 the following rules shall apply:
(a) the market share shall be calculated on the basis of market sales value data; if market sales value data are not available, estimates based on other reliable market information, including market sales volumes, may be used to establish the market share of the undertaking concerned;
(b) the market share shall be calculated on the basis of data relating to the preceding calendar year;
(c) the market share held by the undertakings referred to in point (e) of the second subparagraph of Article 1(2) shall be apportioned equally to each undertaking having the rights or the powers listed in point (a) of the second subparagraph of Article 1(2);
(d) the market share of a licensor on a relevant market for the licensed technology rights shall be calculated on the basis of the presence of the licensed technology rights on the relevant market(s) (that is the product market(s) and the geographic market(s)) where the contract products are sold, that is on the basis of the sales data relating to the contract products produced by the licensor and its licensees combined;
(e) if the market share referred to in Article 3(1) or (2) is initially not more than 20 % or 30 % respectively, but subsequently rises above those levels, the exemption provided for in Article 2 shall continue to apply for a period of two consecutive calendar years following the year in which the 20 % threshold or 30 % threshold was first exceeded.
