Currency translation impactDifferent “reporting” currencies lead to different results:

Changes in different reporting currencies are not readily comparablesuch effects are neither gains nor losses but mainly mathematical effects=> size of the effects reflects global positioning of sales and costs=> rule of thumb of mathematical impact at Ciba:

1% change in USD/CHF = CHF 6-7 million EBIT impact Don’t extrapolate1% change in EUR/CHF = CHF 5-6 million EBIT impact with larger changes
