ATP Oil & Gas Corporation, incorporated in 1991, is an offshore oil and gas development and production company operating in the Gulf of Mexico and the North Sea. The primary objectives of the company are to develop already-discovered reserves not strategic to major or exploration-oriented oil and gas companies and to achieve a high rate of return for ATP from such low-risk developmental projects. ATP s expansion from operations on the Outer Continental Shelf into deepwater in the Gulf of Mexico and extension into the North Sea significantly increase the opportunities for the company. ATP became a public company in February 2001 and is traded on the NASDAQ under the symbol ATPG.
