Expiration time is the time of day by which all exercise notices must be received on the expiration date. Technically, the expiration time is currently 11: 59AM on the expiration date, but public holders of option contracts must indicate their desire to exercise no later than 5: 30PM on the business day preceding the expiration date. The times are Eastern Time. See also Expiration Date.
