The index was created in 1985 with a base value set to 250 on February 1 of that year. After reaching a level of nearly 800 on December 31, 1993, the index level was halved on January 3, 1994.

In-,at- and out-of-the-money strike prices are initially listed. New series are generally added when the underlying trades through the highest or lowest strike price available.

Exercise Style:
June and December. Up to 24 months. The near-term series converts to MNX two business days following June and December expirations. New MML series are normally added on the first business day of January and July.

Last Trading Day:
Trading in MNX/MML options (see "Expiration Months" above) will ordinarily cease on the business day (usually a Thursday) preceding the day on which the exercise & settlement value is calculated.

Settlement of Option Exercise:
MML options cannot be exercised. Once converted (see above), MML options assume the exercise specifications of MNX options. The exercise-settlement value for MNX options, XMS, is computed by dividing the NDX settlement value, NDS, by a factor of 10. Exercise will result in delivery of cash on the business day following expiration.

Position Limit and Exercise Limits:
No position and exercise limits are in effect. Each member (other than a market-maker) or member organization that maintains an end of day aggregate position in excess of 100,000 contracts in NDX, MNX and MML (10 MNX, 10 MML or 10 Mini-NDX options equal 1 NDX full value contract) for its proprietary account or for the account of a customer, shall report certain information to the Department of Market Regulation. The member must report information as to whether such position is hedged and, if so, a description of the hedge employed. A report must be filed when an account initially meets the aforementioned applicable threshold. Thereafter, a report must be filed for each incremental increase of 25,000 contracts. Reductions in an options position do not need to be reported. However, any significant change to the hedge must be reported.

Margin:
Purchases of puts or calls with 9 months or less until expiration must be paid in full. Writers of uncovered puts or calls must deposit / maintain 100% of the option proceeds* plus 15% of the aggregate contract value (current index level x $100) minus the amount by which the option is out-of-the-money, if any, subject to a minimum for calls of option proceeds* plus 10% of the aggregate value and a minimum for puts of option proceeds* plus 10% of the aggregate exercise price amount. (*For calculating maintenance margin, use option current market value instead of option proceeds.) Additional margin may be required pursuant to Exchange Rule 12.10.

8:30 a.m. - 3:15 p.m. Central Time (Chicago time).
