Transocean Announces Redeems Zero Coupon Convertible Debentures

Transocean Inc. announced that it has called its Zero Coupon Convertible Debentures due May 2020 and its 1.5 percent Convertible Debentures due 2021 for redemption on November 15, 2007. The redemption price is $710.29 per $1,000 principal amount of the Zero Coupon Convertible Debentures and $1,000 (plus accrued and unpaid interest) per $1,000 principal amount of the 1.5 percent Convertible Debentures. The Zero Coupon Convertible Debentures and the 1.5 percent Convertible Debentures are convertible into ordinary shares at a rate of 8.1566 and 13.8627, respectively. The right of a holder of a debenture to convert the debenture into ordinary shares will terminate at the close of business on November 14, 2007 in the case of the Zero Coupon Convertible Debentures and on November 9, 2007 in the case of the 1.5 percent Convertible Debentures. If all holders convert before the redemption date, we expect to issue 5,756,702 ordinary shares upon conversion based on the debentures outstanding as of September 30, 2007. The aggregate face value of the debentures was $426 million as of September 30, 2007, and the cost to redeem the debentures is expected to be approximately $421 million, including accrued and unpaid interest, assuming none of the debentures are converted. Transocean expects to recognize a loss on retirement of the notes during the fourth quarter of 2007 of approximately $5 million and plans to use existing cash balances and borrowings under our existing revolving credit facility to fund the redemption.
