In the security option arena, the Nasdaq-100 index option (NDX) is listed on the CBOE, AMEX, Boston Options Exchange, and International Securities Exchange. The contract is a modified market capitalization-weighted index representing 100 of the largest non-financial domestic and international issues listed on the Nasdaq Stock Market. The index was created in 1985 with a base value set to 250 on February 1 of that year. The index level subsequently was halved on January 3, 1994, after reaching a level of nearly 800 on December 31, 1993. Each of these four options exchanges list smaller Mini-Nasdaq-100 Index options contracts (MNX), as well, which are 1/10 the size of NDX.
Because these contracts are fungible, contract specifications at these exchanges mirror one another.
|Price Interval||Strike price intervals are at least $2.50 for certain near-the-money series in near-term expiration months when the Full-size or Mini Nasdaq 100 Index is at a level below 200, and 5 point strike price intervals for other options series with expirations up to one year, and at least 10 point strike price intervals for longer-term options.|

|Settlement Type||A.M., cash settlement|
|Settlement Value||The exercise-settlement value, NDS, is calculated based on the Nasdaq Official Opening Price (NOOP) for each of the component securities on the last business day before the expiration date (usually a Friday). In the event a component security in the Nasdaq 100 Index does not have a Nasdaq Official Opening Price on Settlement Day, the closing price from the previous trading day will be used to calculate the Settlement Value. The exercise-settlement amount is equal to the difference between the exercise-settlement value, NDS, and the exercise price of the option, multiplied by $100. Exercise will result in delivery of cash on the business day following expiration.|
