|The Morgan Stanley Index options family (Biotech, Retail and Oil Services) consists of large actively traded stocks that, based on the research of Morgan Stanley, are the leading companies in their respective sectors. CBOE is the leader in index option trading and is pleased to offer three more sector-specific index products which investors can use to enhance their portfolios.|
|Morgan Stanley Biotech Index (MVB), Morgan Stanley Oil Services Index (MGO) and Morgan Stanley Retail Index (MVR) are equal dollar weighted, meaning that the component securities are represented in approximate equal dollar values. The indexes are re-balanced quarterly after the close of trading on the third Friday of March, June, September, and December. Index divisors were initially calculated to yield a benchmark valued of 100.00 on June 15, 2001. If necessary, a divisor adjustment is made to ensure continuity of the index value. The newly adjusted portfolio becomes the basis for the index value on the first day following the quarterly adjustment. The number of shares of each component stock in the index will remain fixed between quarterly reviews except in the event of certain types of corporate actions. Morgan Stanley Index Options, with European-style exercise, are calculated based on the opening prices of component securities on the business day prior to expiration, and are cash settled.|
