Net gain on legal contingencies. We recognized a net gain on legal contingencies of $96.9 million in 2006, primarily from settlement of pending patent litigation, net of costs incurred. On July 7, 2006, we entered into a settlement agreement with Alcon, Inc., Alcon Laboratories, Inc., and Alcon Manufacturing Ltd. (collectively, Alcon) regarding all pending patent litigation between us and Alcon. The settlement required Alcon to pay us a lump-sum payment of $121 million which was received in July 2006 and was accounted for in the third quarter. The parties agreed to dismiss all pending patent litigation in Delaware and Texas, agreed not to sue each other regarding the patents at issue in those cases, and cross-licensed patents covering existing features of commercially available phacoemulsification products.
