Settlement Value		The exercise-settlement value is calculated using the opening (first) reported sales price in the primary market of each component stock on the last business day (usually a Friday) before the expiration date. If a stock in the index does not open on the day in which the exercise-settlement value is determined, the last reported sales price will be used in calculating the exercise-settlement value.

Exercise will result in delivery of cash on the business day following expiration.
