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 & 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 & 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.) , IJmuiden (Netherlands), and Herzliya (Israel). 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 with the upside of probable and possible reserves. ATP operates its developments & reduces operating risks with projects that have a close proximity to developed markets for natural gas and oil; existing infrastructure of oil and natural gas pipelines and production/processing platforms; and a relatively stable regulatory environment (e.g. the Gulf of Mexico and the North Sea) for offshore natural gas and oil development and production.
