I\'m worried about the sales of the range of fragrances we launched two years ago. In the first year, sales have increased steadily. However, since the beginning of this year, sales have fallen by almost 10%. The reason for this is clear. Several films in SE Asia copy our designs and are now flooding the French market with them. This became a serious problem. Last month, I organised a team of investigators. Up to now, they have found many counterfeit goods, which the police seized and impounded. Yesterday, I contacted several firms who informed me that they had similar problems. They all lost sales because of counterfeiting.
