The Foundation

Stichting Investor Loss Compensation (SILC), established under Dutch law on 15 July 2021, aims to protect and represent the interests of investors and participants when corporations and their individuals act dishonestly, causing significant financial harm to you and the market. Airbus had materially misrepresented and omitted key facts during the height of its scheme to offer and pay bribes via its employees, executives, and business partners to government officials and airline executives around the world in order to obtain illegal business advantages and win orders on hundreds of aircraft. SILC has brought a collective proceeding against Airbus and other related parties in the Netherlands and seeks to obtain fair and adequate damages for affected investors. Joining this claim is a step forward in holding Airbus and others accountable for their actions.

The foundation is unique in its use of the new act on the collective damages claims, WAMCA (Wet Collectieve Afwikkeling Massaschade), which came into force in the Netherlands on January 1st, 2020 and provides an efficient mechanism for collective redress allowing SILC to resolve the claims of all investors in a coordinated manner. If and when needed, SILC will also litigate the claims in various other jurisdictions in order to make investors and participants whole.

The Team

The Foundation is being advised by a leading group of attorneys, academics, and professionals from around the world. These professionals are highly respected and recognized as outstanding leaders around the world in the fields of collective redress and the administration of collective actions.
