Item 5.01 Changes in Control of Registrant.
The description of the Transaction under Item 8.01 is incorporated herein by reference. As a result of the Transaction, Weatherford-Bermuda became a direct, wholly-owned subsidiary of Weatherford-Switzerland. Item 8.01 Other Events.
On February 26, 2009, Weatherford-Bermuda and Weatherford-Switzerland completed a share exchange transaction under the terms of a share exchange agreement, dated as of December 10, 2008 (the "Share Exchange Agreement"), effected by way of a scheme of arrangement under Bermuda law (the "Scheme of Arrangement"), for purposes of changing our place of incorporation from Bermuda to Switzerland (collectively, the "Transaction"). In the Transaction, each holder of Weatherford-Bermuda Common Shares outstanding immediately prior to the Transaction received one Weatherford-Switzerland Registered Share in exchange for each outstanding Weatherford-Bermuda Common Share. As a result of the Transaction, Weatherford-Bermuda became a direct, wholly-owned subsidiary of Weatherford-Switzerland.
Prior to the Transaction, the Weatherford-Bermuda Common Shares were registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and listed on the New York Stock Exchange ("NYSE") under the symbol "WFT." As a result of the Transaction, all of the Weatherford-Bermuda Common Shares were exchanged for Weatherford-Switzerland Registered Shares. Accordingly, Weatherford-Bermuda requested that the NYSE file with the Securities and Exchange Commission (the "Commission") a Form 25 to remove the Weatherford-Bermuda Common Shares from listing on the NYSE. Weatherford-Bermuda expects to file a Form 15 with the Commission to terminate the registration of the Weatherford-Bermuda Common Shares and suspend its reporting obligations under Sections 13 and 15(d) of the Exchange Act.
Pursuant to Rule 12g-3(a) promulgated under the Exchange Act, the Weatherford-Switzerland Registered Shares are deemed registered under Section 12(b) of the Exchange Act. The Weatherford-Switzerland Registered Shares were approved for listing on the NYSE and began trading under the symbol "WFT," the same symbol under which the Weatherford-Bermuda Common Shares previously traded, on February 26, 2009.
