4.6 Cases data requirements

4.6.1 Case (i) : only Klimisch 1 studies available

By contribution of a category (1) report (“reliable without restrictions”), the share of that
contributor is considered as paid for the relevant end point. This applies also for any other
parties who contribute reports of equal quality. The cost allocation against this end-point is
then borne only by the remaining (non-contributory) parties. If any reports are jointly owned
by a number of contributors, each would be considered to have met his obligation for that
endpoint from a cost share perspective.

4.6.2 Case (ii) : Klimisch 1 & 2 studies available

If reports from both category (1) and (2) (“reliable with restrictions”) are available for
the same end point, the report with the higher rating will be used as the key study for cost
allocation purposes. Contributors supplying a lower rated report contribute according to the
difference in value of their study to the key one selected. Other (non-contributory) parties
support the cost on the basis of the key study value.

4.6.3 Case (iii) : Only Klimisch 2 studies available

If a report of category (1) standard is not in existence and only one or more reports
of category (2) are available, the report with the highest assigned value will be selected
as the key study for cost allocation. Contributory members will pay by difference (as above)
whilst others will support the cost on the basis of the key study value.
