Notes

Ascent Resources plc has a diversified portfolio of hydrocarbon exploration and development interests across five countries in Europe: Italy, Switzerland, Hungary, Slovenia and Netherlands. Its portfolio contains a solid base of field redevelopment projects with selected exposure to exploration upside. The portfolio is focussed on gas and, with the exception of the shallow water Netherlands project, all of its projects are located onshore where operating and development costs are substantially lower than they would be offshore.
