ATP Oil & Gas Corporation

ATP Oil & Gas Corporation (NASDAQ: ATPG) is engaged in the acquisition, development and production of natural gas and oil properties in the Gulf of Mexico and the North Sea. ATP acquires and develops properties, many of which have proved undeveloped reserves (“PUD’s”) at the time of acquisition that are economically attractive to ATP, but not strategic to exploration-oriented oil and gas companies. Such strategy provides ATP with the assets to develop and produce without the risk, cost and time involved in traditional exploration. Since its inception in 1991, the company has had an exceptionally strong development success record of 98% of taking projects to production that were previously undeveloped and non-producing. ATP is headquartered in Houston, Texas, with additional offices in Guildford, Surrey (U.K.) and IJmuiden (Netherlands). ATP trades on the NASDAQ Global Select Market under the symbol ATPG.

ATP creates value for its shareholders through the acquisition and development of significant proved undeveloped reserves frequently with the upside of probable and possible reserves.
