The document outlines a pilot project to collect data on the impacts of illicit trade on leading companies in the Stockholm OMX 30 stock market index. The project is funded by the Swedish Confederation of Enterprise and will involve sending questionnaires and conducting interviews with companies to anonymously obtain estimates of losses in sales volumes, trademark damage, and countermeasure costs due to illicit trade both within and outside of Sweden. The collected data aims to provide evidence to increase political prioritization of addressing illicit trade and its effects on businesses.
