Listing and first trading day of Weatherford on 17 November 2010
The Management Committee of SIX Swiss Exchange is weighing the possibility of including Weatherford International in the SMI and SLI on an extraordinary basis. For that to occur, the stock - based on its order book turnover and average market capitalization during the months of December, January and February - must rank at least 15th for inclusion in the SMI and 20th for inclusion in the SLI. Determination of the ranking will be made in accordance with the current rules governing the SMI index family.
Upon fulfillment of the aforementioned criteria, Weatherford will be added to the SMI and/or SLI after the close of trading on the Eurex monthly expiration date of 18 March 2011 for effect as of 21 March 2011.
