Underlying
The NASDAQ-100® Index is a modified market capitalizationweighted index 
composed of securities issued by 100 of the largest non-financial companies 
listed on the Nasdaq Stock Market.
The value of the Index equals the aggregate value of the Index share weights, 
also known as the Index Shares, of each of the Index Securities multiplied 
by each such security’s Last Sale Price on Nasdaq (which may be the Nasdaq 
Official Closing Price), and divided by the divisor of the Index. If trading in an 
Index Security is halted on its primary listing market, the most recent Last Sale 
Price for that security is used for all index computations until trading on such 
market resumes. Likewise, the most recent Last Sale Price is used if trading in 
a security is halted on Nasdaq before the market is open. Nasdaq calculates 
and disseminates the NASDAQ-100® Index once per second from 09:30:01 
to 17:16:00 ET. The closing value of the Index may change up until 17:15:00 
ET due to corrections to the Last Sale Price of the Index Securities. The Index 
began on January 31, 1985 at a base value of 125.00, as adjusted.

Settlement Value
Settlement Value Symbol: XQO
Cash settlement - equal to the difference between the final settlement value 
and the strike price of the contract, multiplied by $100. Exercise will result in 
delivery of cash on the business day following expiration.
The NDX final settlement value, XQO, is calculated at the open of trading on the 
expiration date (usually a Friday) based on the Nasdaq Official Opening Price 
(NOOP) that day for each of the component securities. In the event a component 
security in the NASDAQ-100® Index does not have a NOOP, the last sale price of 
that security on NASDAQ will be used to calculate the XQO settlement value.
