When we refer to the change in our sales on a “comparable” basis, we mean that we exclude the impact of exchange rate movements and changes in Group structure (acquisitions and divestments of interests in entities and rights to products, and changes in consolidation method for consolidated entities).

We exclude the impact of exchange rates by recalculating sales for the prior period on the basis of exchange rates used in the current period. We exclude the impact of acquisitions by including sales from the acquired entity or product rights for a portion of the prior period equal to the portion of the current period during which we owned them, based on sales information we receive from the party from whom we make the acquisition.

Similarly, we exclude sales in the relevant portion of the prior period when we have sold an entity or rights to a product.

For a change in consolidation method, the prior period is recalculated on the basis of the method used for the current period.
