Airbag certificates offer conditional capital protection against downside losses to a predefined minimum level while allowing unlimited participation in upside movements. They provide protection similar to an airbag in a car, protecting effectively up to a point but not for severe crashes. The protection level does not change over the lifetime of the product. While airbag certificates offer upside potential if the underlying trades sideways or lower, investors must understand the risks, as protection is only provided up to the minimum level and not beyond.
