Exercise notices properly tendered on any business day will result in delivery of the underlying stock on the third business day following exercise.
Position and Exercise Limits:
Limits vary according to the number of outstanding shares and past six-month trading volume of the underlying stock. The largest in capitalization and most frequently traded stocks have an option position limit of 250,000 contracts (with adjustments for splits, re-capitalizations, etc.) on the same side of the market; smaller capitalization stocks have position limits of 200,000, 75,000, 50,000 or 25,000 contracts (with adjustments for splits, re-capitalizations, etc.) on the same side of the market. The number of contracts on the same side of the market that may be exercised within any five consecutive business days is equal to the position limit. Equity option positions must be aggregated with equity LEAPS positions on the same underlying for position and exercise limit purposes. Exemptions may be available for certain qualified hedging strategies.
