Usually, the final payout is the amount invested, plus the gain in the underlying stock or index times a note-specific "participation rate", which can be more or less than 100%. For example, if the underlying equity gains 50% during the investment period and the participation rate is 80%, the investor receives 1.40 dollars for each dollar invested. If the equity remains unchanged or declines, the investor still receives one dollar per dollar invested (as long as the issuer does not default). Generally, the participation rate is better in longer maturity notes, since the total amount of interest given up by the investor is higher.
