Index Components
Multiplier:
$100.
Strike Prices:
Strike prices are set above and below the index level in increments of 2 1/2 or 5 points.

Expiration Date:
Saturday following the third Friday of the expiration month.
Expiration Months:
Generally, up to three near-term months plus up to three additional months on the March quarterly cycle (March, June, September, December).
Exercise Style:
European - GTC options generally may be exercised only on the last business day before expiration.
Last Trading Day:
Trading in GTC options will ordinarily cease on the business day (usually a Thursday) preceeding the day on which the exercise-settlement value is calculated.
Settlement of Option Exercise:
Exercise will result in delivery of cash on the business day following expiration. The exercise-settlement value, GTZ, is calculated using the first (opening) 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 on which the exercise-settlement value is determined, the last reported sales price in the primary market will be used in calculating the exercise-settlement value. The exercise-settlement amount is equal to the difference between the exercise-settlement value and the exercise price of the option, multiplied by $100.
Position and Exercise Limits:
The position and exercise limits are 100,000 contracts on the same side of the market with no more than 60,000 contracts in the near-term expiration month. An index option hedge exemption for public customers may be available for certain diversified portfolios, which may expand the position limit up to an additional 75,000 contracts. In addition, proprietary accounts of member organizations may receive an exemption up to 200,000 contracts for the purpose of facilitating public customer orders.
Margin:
Purchases of puts or calls with 9 months or less until expiration must be paid for 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 contract 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.
