The yield amount of Structured Notes could either be known beforehand and the entire nominal value or a part thereof is paid out depending on the development of the underlying assets. Or the yield amount, just as for Structured Bonds, is not known beforehand and depends on how well the underlying assets perform. Unlike Structured Bonds the price is less dependent on the development of interest rates, but is more sensitive to the development of underlying assets, especially if the underlying asset approaches the capital protection barrier. The yield to maturity is not calculated, however in structured notes with a fixed yield, an aliquot interest return (AIR) is count on.
